Sun Dec 15 13:01:17 1996 David L. Levine <levine@cs.wustl.edu>
* ace/OS.i: removed spurious "*/" after an #endif. Thanks to Harry
Gunnarsson for pointing this out.
* ace/Naming_Context.cpp: reordered initializations in default ctor
to match declaration order
* ace/Svc_Conf_y.cpp: added parens to a couple of combined
assignments/conditionals to avoid compiler warnings
* include/makeinclude/platform_sunos5_sunc++*.GNU: reverted
SOLINK step back to creating real .so files, because it
seems to be necessary, sometimes, for template instantiation
* netsvcs/lib/Server_Logging_Handler.cpp: removed ACE_INLINE's
* tests/MM_Shared_Memory_Test.cpp: declare shm_key as char[]
instead of char *, so that the string gets put into the data
segment rather than the text segment. The string gets modified,
which causes a core dump with the g++/SunOS5.5 build if the string
is in the text segment.
Sun Dec 15 10:29:20 1996 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu>
* netsvcs/servers/svc.conf: Removed the "lib" prefix for the
netsvcs DLL. This is now added automatically by the
ACE::ldfind() operation.
* ace/SString.cpp (ACE_CString): Removed the #pragmas for Win32.
They aren't necessary since we should replace the ACE_USHORT16
cast with a char cast. Thanks to Amos Shapira <amos@dsi.co.il>
for reporting this.
Sat Dec 14 14:25:38 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* build/SunOS5.5/tests/UPIPE_SAP_Test.cpp (main): Fixed several
minor bugs with UPIPE_SAP_Test.cpp.
* ace/OS.i (thr_join): Added implementations for Solaris threads
and most versions of POSIX pthreads where ACE_hthread_t and
ACE_thread_t are the same type!
* ace/OS: Began adding hooks so that we can eventually move away
from the current split between ACE_thread_t and ACE_hthread_t
and unify them via ACE_Thread_ID.
* ace/{OS,Thread}.h: Changed the interface of thr_getprio() so
that it takes an int & rather than an int *.
* ace/OS.i (thr_getprio): Fixed a minor bug for Win32 where we
weren't depositing the thread priority into the return value!
* Makefile: Changed the order in which things are built so that
netsvcs are built right after libACE, followed by the tests.
Sat Dec 14 11:54:22 1996 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu>
* apps/Gateway/Gateway/Consumer_Map: Change the Consumer_Map class
so that it was no longer templatized. There isn't any point in
doing this since we aren't going to be changing these types for
this application.
* apps/Gateway/Gateway: Factored out the code for selecting the
concurrency strategy into a separate *.h file called
Concurrency_Strategy.h.
* apps/Gateway/Gateway: Began revising the Gateway application to
use the new ACE Event Channel.
* ace/Svc_Handler: Now that we've got put() and svc() with no-op
defaults in class ACE_Task_Base, we don't need them in
ACE_Svc_Handler anymore, so I removed them!
* ace/Task: Finally got sick of having to provide no-op
open()/put()/close() routines in all ACE_Task subclasses, so I
changed these methods from pure virtual to virtual with default
no-op behavior. Updated all the tests, as well.
Sat Dec 14 11:39:15 1996 David L. Levine <levine@cs.wustl.edu>
* ace/{Module,Stream,Svc_Handler,Synch_T,Task_T}.cpp and Synch_T.i:
removed ACE_INLINE qualifier from functions in .cpp files; in
the case of Synch_T, moved ACE_INLINE functions from .cpp to .i file
* apps/Gateway/Gateway/Routing_Table.cpp,
examples/ASX/Event_Server/Event_Server/Peer_Router.cpp,
examples/ASX/UPIPE_Event_Server/Peer_Router.cpp:
removed ACE_INLINEs from .cpp files
* ace/CORBA_Handler.h and ace/Token_Collection.{h,cpp}:
changed __INLINE__ to __ACE_INLINE__
* ace/Svc_Conf_y.cpp: commented out unused arguments to
suppress compiler complaints
Fri Dec 13 22:07:11 1996 David L. Levine <levine@cs.wustl.edu>
* include/makeinclude/platform_sunos5_sunc++*.GNU: replaced
SOLINK step in build of shared objects for SunOS5 with SunC++
with symlink from .so to .o file.
* ace/config-vxworks*.h: added ACE_NEEDS_SYSTIME_H to VxWorks
configs because it's needed with inlining
* include/makeinclude/platform_vxworks*.GNU: cleaned up VxWorks
config files
Fri Dec 13 00:53:34 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace: Replaced all uses of
#if defined (.....) // ....
with
#if defined (.....) /* ... */
so that broken C++ compilers won't complain. Thanks to
John Cosby <John.D.Cosby@cpmx.saic.com> for reporting this.
* ace/Thread.i: Updated the signature of getprio() and setprio()
so that they take ACE_hthread_t. Thanks to Wayne Vucenic
<wvucenic@netgate.net> for finding this.
* Reran all the tests on NT and Solaris. Everything seems to
work. Therefore, incremented the version number to 4.1 and put
it out for ftp and http.
Thu Dec 12 18:51:04 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* tests/Priority_Task_Test.cpp (svc): Added a new test to exercise
the new "priority" feature of ACE_OS::thr_create()
(which is also available to ACE_Task).
* ace/Thread: Added getprio() and setprio() methods to ACE_Thread.
Fri Dec 13 13:44:12 1996 David L. Levine <levine@cs.wustl.edu>
* ace/config-vxworks*.h: added ACE_NEEDS_SYSTIME_H to VxWorks
configs because it's needed with inlining
* include/makeinclude/platform_vxworks*.GNU: cleaned up VxWorks
config files
Thu Dec 12 18:51:04 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace: Added a new macro called ACE_UNUSED_ARG() to keep
the compiler from outputting warnings about unused
arguments. So far, this is mostly done for Win32, but it
should be easy to do it for other compilers. Thanks
to Matthias for these changes.
* ace/OS.cpp: Added support so that thread priorities will
automatically be set when we spawn threads using
ACE_OS::thr_create().
* ace/OS.cpp: Simplified the logic for handling NULL thr_handles
and thr_ids. Now, we set all this stuff in one place at the
beginning of the function, rather than recomputing it all over
the place.
* ace/config-aix-{3.2.5,4.1.x}.h: Added the
ACE_HAS_RECURSIVE_THR_EXIT_SEMANTICS flag.
* ace/Thread_Manager.cpp (ACE_Thread_Control): Conditionally
compiled the logic for calling this->exit() in the destructor
for ACE_Thread_Control so that we only make this call if
ACE_HAS_RECURSIVE_THR_EXIT_SEMANTICS is *not* set. This will
prevent infinite recursion on platforms like AIX. Thanks to
Chris Lahey for reporting this.
* apps/Gateway/Gateway/Channel.cpp (recv_peer): Added the logic
that makes sure we don't get screwed up by partial headers.
Thanks to Chris Cleeland for this.
Thu Dec 12 20:55:02 1996 David L. Levine <levine@cs.wustl.edu>
* include/makeinclude/platform_sunos5_sunc++*.GNU: removed
SOLINK step in build of shared objects for SunOS5 with SunC++:
it's not necessary.
Thu Dec 12 03:48:26 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* ace/Naming_Context: Modified ACE_Naming such that on Win32, you
can use ACE_Registry_Name_Space.
* ace/Registry_Name_Space: ACE_Registry_Name_Space is a Name_Space
which uses ACE_Registry as the persistence mechanism. Win32
clients of ACE_Naming can now start using (the more robust and
reliable) Registry persistence without any major code changes.
* tests/Naming_Test.cpp: Added the use of Registry_Name_Space to
the test if we are on Win32 and UNICODE is turned on.
* examples/Registry: Fixed UNICODE behavior of the tests
Wed Dec 11 20:33:28 1996 Douglas C. Schmidt <schmidt@lindy.cs.wustl.edu>
* ace/Synch_T.h: Added a warning that indicates why it isn't
possible to use ACE_Process_Condition<ACE_Process_Mutex> on
Win32...
* tests/TSS_Test.cpp: Moved the Errno class to a file
TSS_Test_Errno.h and replaced the Errno class with the #include
"TSS_Test_Errno.h" to work around "features" with AIX C++'s
template instantiation scheme.
* ace/OS.i (inet_aton): Replaced the use of ((ACE_UINT32) -1) with
((ACE_UINT32) ~0). I expect this is more portable...
* tests/run_tests.bat: Added "Service_Config_Test" to the
run_tests.bat file.
Tue Dec 10 22:59:26 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* tests: Added Service_Config_Test to Win32 makefiles.
* ace/OS.i (inet_aton): We need to cast htonl to (long)
* tests: Added/Fixed UNICODE behavior of the following:
MM_Shared_Memory_Test.cpp
Mem_Map_Test.cpp
Mutex_Test.cpp
Naming_Test.cpp
Process_Mutex_Test.cpp
SPIPE_Test.cpp
Time_Service_Test.cpp
Tokens_Test.cpp
UPIPE_SAP_Test.cpp
* netsvcs/lib: Added/Fixed UNICODE behavior of the following:
ACE_TS_Clerk_Processor::poolname_
Tue Dec 10 00:33:08 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* tests/Service_Config_Test.cpp (main): Added a new method called
run_test() to ensure that ACE_Service_Config daemon is destroyed
before we try to end the test.
* ace/OS.i (inet_aton): We need to cast -1 to (ACE_UINT32).
* tests/Process_Mutex_Test.cpp (main): Added a minor change to
make gcc happy by moving the definition of int i *outside* the
loop. Thanks to Thilo Kielmann
<kielmann@informatik.uni-siegen.de> for reporting this.
* ace/OS.h: gcc complains about memcmp, memcpy, strcmp, and strcpy
(from ACE_OS::) being used before defined inline. This is due
to the include of SString.h at the end of OS.h. So I reordered
things in accordance to the changes from Thilo Kielmann
<kielmann@informatik.uni-siegen.de>.
* build/SunOS5.5/examples/Shared_Malloc/test_multiple_mallocs.cpp:
Changed the definition of char *base_addr to void *base_addr.
* ace/Memory_Pool.cpp (ACE_MMAP_Memory_Pool_Options): Changed the
definition of char *base_addr to void *base_addr.
* Put out what is hopefully the final beta release of 4.0.33.
* ace/Message_Queue: Added the enqueue() method again to maintain
backwards compatibility. Thanks to Karlheinz for pointing out
the need for this.
* ace/Service_Config.h: The svc.conf factory functions were
begin defined as extern "C", but the function pointer defined in
the ACE_Static_Svc_Descriptor struct is not declared as extern
"C", therefore, there was a mismatch. Here's how to fix this:
In Service_Config.h, before the struct ACE_Static_Svc_Descriptor
add:
extern "C" {
typedef ACE_Service_Object *(*ACE_SERVICE_ALLOCATOR)(void);
}
Then in the struct alloc_ field was changed as follows:
from: ACE_Service_Object *(*alloc_)(void);
to: ACE_SERVICE_ALLOCATOR alloc_;
Thanks to Chuck Gehr for this.
* ace/Memory_Pool.cpp (commit_backing_store_name): Changed uses of
"counter" from int to size_t to remove warnings.
* ace/ACE.cpp: Reimplemented the ACE::daemonize() method to
conform to the latest version in Richard Steven's new UNP book.
* ace/INET_Addr.cpp (set): Replaced the use of ACE_OS::inet_addr()
with ACE_OS::inet_aton(). Thanks to W. Richard Stevens for this
idea ;-).
* ace/OS: Added a new function called inet_aton(), which is based
on a new POSIX socket addressing function that is non-ambiguous
in its return value (unlike inet_addr).
* tests: Added a new Service_Config_Test.cpp to make sure that the
timeout features mentioned below work.
* ace/Service_Config.cpp: Changed the implementation of
run_{reactor,proactor,reactorEx}_event_loop so that it returns
if the corresponding handle_events() method times out.
Thanks to Phil Logan <phill@in.ot.com.au> for reporting
this.
* ace/LSOCK_Stream: Moved get_remote_addr() from the private part
of the class and implemented it using get_local_addr(). This
fixes problems that previously occurred when using the
ACE_Connector with ACE_LSOCK_Stream. Thanks to Stuart Powell
<stuartp@in.ot.com.au> for this suggestion.
Mon Dec 9 22:03:30 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* examples/Threads: Updated the test.mak and test.mdp files to
reflect the new name changes. Thanks to Matthias for this.
* ace/ACE.cpp (ldfind): Added new code that will work if the
"base" part of the filename to look for is the same on both UNIX
and NT. The library name will be made up of three parts
[ACE_DLL_PREFIX]base part[ACE_DLL_SUFFIX], where prefix is "lib"
on UNIX and nothing on NT and suffix is ".dll" on NT and ".so"
on UNIX. If either prefix or suffix are missing from the
filename you supply to ldfind they will be added
automagically. This all will work independent from the pathname,
which will be treated completely separately from the filename
and can contain either UNIX style or NT style separators.
Examples:
Source NT UNIX
===============================================================
netsvc netsvc.dll libnetsvc.so
(PATH will be evaluated) (LD_LIBRARY_PATH evaluated)
libnetsvc.dll libnetsvc.dll libnetsvc.dll + warning
netsvc.so netsvc.so + warning libnetsvc.so
..\../libs/netsvc ..\..\libs\netsvc.dll ../../libs/libnetsvc.so
(absolute path used) (absolute path used)
The first and the last of these 4 examples is the way the new
functionality is supposed to be used. You simple supply the
pathname and the base part of the filename and ldfind will
figure everything out.
Thanks to Tilo Chris for this code.
* ace/OS.h: Added a new macro called ACE_DLL_PREFIX, which is
defined to "" on Win32 and "lib" on UNIX. Thanks to Tilo for
this.
* ace/Reactor.cpp (detach): After further thought, I
have commented out the
eh->reactor (0);
call since I don't think we really need it.
* ace/Reactor.cpp (detach): There was a problem with
ACE_Reactor::detach().
The following lines:
// Reinitialize the Reactor pointer to 0.
eh->reactor (0);
should be moved before:
eh->handle_close (handle, mask);
This will render the reactor handle not available in the
handle_close method but at least handle_close can delete itself.
Thanks to Luca for reporting this.
* examples/Reactor/Ntalker: Replaced the use of ACE_OS::getopt()
with the ACE_Get_Opt iterator. Thanks to Alexandre Karev
<Alexandre.Karev@cern.ch> for suggesting this.
* ace/OS.h: Moved the #endif /* ACE_HAS_DCETHREADS ||
ACE_HAS_PTHREADS */ once again in order to make sure that the
right things happen when #if defined (ACE_HAS_THREADS) is
*false*. Thanks to Robert Lyng <RLyng@msmail.hsii.ccare.com>
for reporting this.
Mon Dec 9 02:06:48 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* ace/SString: Made accessors return const references.
* ace/OS.h: Added macro ACE_WIDE_STRING which allows the
conversion of char* to wchar_t* when UNICODE is turned on.
* ace: Added/Fixed UNICODE behavior of the following:
/* Local_Name_Space */
ACE_Local_Name_Space_T::context_file_
/* ACE */
ACE::basename
/* Token */
ACE_Token::ACE_Token
/* Synch */
ACE_File_Lock::ACE_File_Lock
/* SPIPE_Addr */
ACE_SPIPE_Addr::addr_to_string
ACE_SPIPE_Addr::set
/* FILE_Addr */
ACE_FILE_Addr::addr_to_string
/* DEV_Addr */
ACE_DEV_Addr::addr_to_string
/* Addr */
ACE_Addr::addr_to_string
ACE_Addr::string_to_addr
Note: These two were removed from the base class since they are
not common to all Address classes.
/* Malloc */
ACE_Allocator_Adapter::ACE_Allocator_Adapter
ACE_Malloc::ACE_Malloc
/* Process */

Sun Dec 8 19:00:45 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu>
* ace/Reactor.cpp (handle_events): Updated this method to use the
ACE_Countdown_Time::update method after the mutex has been
acquired.
* ace/Time_Value.cpp (update): Added an ACE_Countdown_Time::update
method that calls stop and start. This is useful for methods
such as ACE_Reactor::handle_events that need to update timeout
values after acquiring locks, but before waiting on the
demultiplexing mechanism (e.g. select).
* ace/ReactorEx.cpp (handle_events): Modularized the
implementation of handle_events. Now it uses helper functions
to significantly simplify the implementation. Also updated the
header file documentation.
* ace/Timer_Queue: Added a timer_skew_ data member and accessor
methods to ACE_Timer_Queue. Also added an expire method that
calls gettimeofday and adds the timer_skew_ for you. These
changes will help simplify Reactor, Proactor, and ReactorEx
code.
* ace/Reactor : Removed timer_skew_. This code now just calles
timer_queue->expire () with no parameters. Very clean.
* ace/ReactorEx : Removed timer_skew_ code.
* ace/Proactor : Removed timer_skew_ code.
* examples/Proactor/test_proactor.cpp: Fixed this application so
that it exits when all the data has been sent and received.
Previously, it used a cool timeout mechanism to "guess" when all
the data had been received. Ahh, but we can't have too much
fun, or people start to get nervous.
* ace/Service_Config.cpp (run_reactorEx_event_loop (Time_Value)):
Fixed the implementation of this method. It now handles
reactorEx events until end_reactorEx_event_loop is called, or
the specified time value expires. Also fixed the
run_proactor_event_loop (Time_Value) method.
* examples/ReactorEx/test_timeout.cpp: Added a new example
application that shows how to use
Service_Config::run_reactorEx_event_loop with timeouts. Check
the examples/ReactorEx/README file for more details.
* examples/Proactor/test_timeout.cpp: Added a new example
application that shows how to use
Service_Config::run_proactor_event_loop with timeouts. Yes, this
screams for common dispatcher interfaces for Reactor, Proactor,
and ReactorEx.
Sun Dec 8 10:27:19 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Service_Manager.cpp (init): Changed all uses of "int port"
to "u_short port" to be consistent with socket types.
* ace/ACE.cpp (bind_port): Changed all uses of "int port" to
"u_short port" to be consistent with socket types.
* ace/Remote_Name_Space.cpp: Changed all uses of "int port" to
"u_short port" to be consistent with socket types.
* ace/SV_Semaphore_{Simple,Complex}: Changed all uses of "int n"
to "u_short n" to be consistent with the SYSV types!
* ace/OS.h: Moved the location of the ACE_HAS_USING_KEYWORD macros
until *after* we #include "ace/Time_Value.h". Thanks to
Matthias for this.
* ace/Signal.cpp: Finished implementing the
ace_signal_handlers_dispatching logic, which wasn't done
entirely earlier. Thanks to Alexandre Karev
<Alexandre.Karev@cern.ch> for reporting this.
* netsvcs/servers/main.cpp (main): Fixed several small bugs in the
netsvcs main test program. Thanks to Alexandre Karev
<Alexandre.Karev@cern.ch> for finding this.
* ace/Reactor: Removed the timer_skew_ data member from the
ACE_Reactor since this is now covered by the
ACE_Timer_Queue.
* ace/Reactor.cpp (handle_events): Added the new version of the
ACE_Countdown_Time to simplify the code.
* ace/Time_Value: Added a new class called ACE_Countdown_Time,
which is used by the Reactor, ReactorEx, and Proactor to keep
track of how much time elapsed.
* ace/config-win32-msvc4.0.h: Added a change that forces the MSVC
compiler to reference the proper Winsock - lib during linking of
ACE. This change is necessary because a) in the release version
the link to the winsock.lib was completly missing and b) only
wsock32.lib has been included (which is wrong when WinSock2 is
used). Thanks to Matthias for this.
* ace/Module.cpp (ACE_Module): Added code to zero-out the
q_pair_[2] pointers. Thanks to Matthias for this.
* tests: Removed the argv name from most main() functions so that
we don't get warnings...
* examples/Threads: Fixed some errors in the threads examples
directory, most of which are ambigious overloads. Also included
a (MSVC 4.1) makefile for all tests in this directory. Thanks
to Matthias for this.
* examples/Threads: Renamed all the files by removing the word
"test_" at the beginning. This is redundant!
* tests/TSS_Test.cpp: If we are running AIX (i.e., if
ACE_TEMPLATES_REQUIRE_PRAGMA), then conditionally avoid
compiling this test program because it doesn't work unless we
split off class Errno due to AIX's rules for generating
templates. This is too much work to get right...
* ace/OS.i (thr_self): Updated the conditional compilation tests
so that we check for ACE_HAS_THREAD_SELF first. Thanks to Chris
Lahey for this.
* ace/{config-osf1-3.2.h,config-aix-4.1.x.h}: Updated this file so
that is has the new ACE_HAS_THREAD_SELF macro, which indicates
that the platform uses thread_self() rather than pthread_self().
* ace/config-aix-4.1.x.h: According to Chris Lahey
<Chris_Lahey@cccis.com>, AIX 4.1.x should have ACE_HAS_PTHREADS
rather than ACE_HAS_DCETHREADS.
* ace/Thread_Manager: Removed the thread_descriptor_i() methods
and replaced them by generalizing the find() method to become
find_thread() and find_hthread(). Thanks to Hamutal Yanay
<Hamutal_Yanay@mail.icomverse.com> for suggesting this.
Sun Dec 8 14:39:53 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu>
* ace/Timer_Queue: Added a timer_skew_ data member and accessor
methods to ACE_Timer_Queue. Also added an expire method
that calls gettimeofday and adds the timer_skew_ for you. These
changes will help simplify Reactor, Proactor, and ReactorEx
code.
Sat Dec 7 01:14:04 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* tests/Process_Mutex_Test.cpp: Added new test which checks the
functionality of a ACE_Process_Mutex. Abandoned mutexes can be
created by selecting the correct command-line arguments.
* examples/Reactor/ReactorEx/test_reactorEx.cpp: Reverted back to
old scheme which does not utilize traits.
* ace/Task_T.h: Removed the synchronization trait in Task. This is
because template typedefs are only supported by a few
platforms. Sigh ;-)
Sat Dec 7 16:55:37 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Thread_Manager.cpp: Because thread_descriptor_i() only returns
0 or -1 on failure the code for
ACE_Thread_Manager::thr_self(ACE_hthread_t &) should read:
if (-1 == this->thread_descriptor_i (id, td))
return -1;
handle = &td.thr_handle_;
Thanks to Matthias for reporting this.
* ace/OS: Added a new static instance of ACE_thread_key_t to work
around the pthreads implementation on MVS (which doesn't store
TSS keys as ints!). Thanks to Chuck Gehr for reporting this.
* ace/config-mvs.h: Added #define ACE_TEMPLATES_REQUIRE_SOURCE for
MVS C++. Thanks to Chuck Gehr for reporting this.
* ace/Signal.cpp: ace_dispatcher was being set to
ace_signal_handlers_dispatch() which calls
ACE_Sig_Handlers::dispatch (when ACE_HAS_SIC_C_FUNC is defined),
whereas it was set to ACE_SigHanlder::dispatch (no s) if not
defined. I intended to set this to ace_signal_handler_dispatch
(no s). Thanks to Chuck Gehr for reporting this.
* ace/Makefile: Fixed a small typo where I wasn't matching char
*getenv in the sed regular expression.
* ace/{OS,Synch}: Moved various classes around so that things will
compile correctly when ACE_WIN32 is defined but ACE_HAS_THREADS
is *not* defined. Thanks to Robert Lyng
<RLyng@msmail.hsii.ccare.com> for reporting this.
Sat Dec 7 16:55:37 1996 Matthias Kerkhoff <make@cs.tu-berlin.de>
* ace/Module: Added some values to the enum so Module clients
can decide whether the reader, the writer or both should be
automatically deleted.
* ace/{Stream,Module,Task}: Changed some function arguments
from u_long to int (because enums are represented as ints).
* ace/Task: Added a new virtual function to ACE_Task_Base
(module_closed), which by default calls
ACE_Task_Base::close(1). Please note the changed flags
argument. This allows clients to differ between calls
originated from a Module and/or Stream from those which
result from ~ACE_Task_Exit(). ~ACE_Task_Exit() calls
ACE_Task_Base::close(0). This may be or not be a problem to
existing applications. It may (hopefully not)
be neccessary to change ACE_Task_Base::module_close back to
calling ACE_Task_Base::close(0).
Fri Dec 06 14:44:20 1996 David L. Levine <levine@cs.wustl.edu>
* ace/OS.cpp: added ::spa () function to allow command line args
to be passed to programs in VxWorks
* ace/OS.i: (ACE_OS::gettimeofday): VxWorks returns nsec instead
of usec, so convert
Fri Dec 6 01:21:48 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* examples/Reactor/ReactorEx/test_reactorEx.cpp: Rewrote the
example such that the test now uses the new Notification
Strategy scheme in ACE. This allows a message queue consumer to
wait in ReactorEx without spawning a new thread, or creating
extra Win32 events. This make the example smaller and much
cleaner.
* ace/Task_T.h: Added synchronization trait to Task.
* ace/Task_T.i (msg_queue): Added a check to delete the old
message_queue if we had created it.
* ace/ReactorEx.cpp (remove_handler): Removed the call to set
reactorEx of the event handler to zero becauses the event
handler may no longer be there after the handle_close()
completes.
Thu Dec 05 21:18:49 1996 David L. Levine <levine@cs.wustl.edu>
* ace/OS.cpp (thr_create): Oops, needed to add another check if
thr_id == 0 before assigning *thr_handle = *thr_id, for systems
such as Solaris 2.4 that don't have PTHREADS.
Wed Dec 4 09:09:56 1996 David L. Levine <levine@cs.wustl.edu>
* ace/Log_Msg.cpp (log): added printout to stderr before call
to exit(). Silent calls to exit() are bad :-}
* performance-tests/Synch-Benchmarks/Options.cpp (print_results):
only use rusage if ACE_HAS_PRUSAGE_T is #defined
* examples/IPC_SAP/SOCK_SAP/CPP-in{client,server}.cpp:
use blocking connect on VxWorks
* ace/config-vxworks*.h: added ACE_LACKS_MPROTECT and
ACE_HAS_STRERROR
* include/makeinclude/platform_vxworks*: removed INCLDIRS and
added indlib.o to GreenHills LIBS
* Makefile (cleanrelease and release): changed "rm -r" of
ACE.tar.gz to "rm -f", that's probably what was meant
Wed Dec 4 00:27:07 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* ace/config-win32-msvc*.0.h: Added NOMINMAX.
* ace/Registry: Removed NOMINMAX and
VC_PLUS_PLUS_NESTED_CLASS_PROBLEM flags from the header file.
The VC_PLUS_PLUS_NESTED_CLASS_PROBLEM flag is no longer needed
and NOMINMAX is defined at the project level. Thanks to
Matthias Kerkhoff <make@cs.tu-berlin.de> for suggesting this.
Mon Dec 2 14:13:44 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace: Changed all occurrences of ACE_Event_Handler
reactorex() to reactorEx() to be consistent. Thanks to
Matthias for suggesting this.
* ace/Message_Queue.cpp (close): We didn't allocate the memory for
the notification_strategy_, so we darn well can't delete it!
Thanks to Matthias for finding this.
* ace/Log_Msg.cpp (ACE_TSS_cleanup): Made the ACE_TSS_cleanup
function extern "C" for MVS C++ and compilers like it... Thanks
to Chuck Gehr for reporting this.
* tests/Naming_Test.cpp (main): Added delete ns_context to close
things down and free up the semaphores. Thanks to David Levine
for suggesting this.
* examples/Reactor/Misc/test_demuxing.cpp (handle_input): Fixed a
"typo" where we were accessing mb->msg_priority() *after*
deleting it! Thanks to Matthias for finding this.
Mon Dec 2 09:57:15 1996 David L. Levine <levine@cs.wustl.edu>
* tests/run_tests.*: updated lists of tests to be run
* tests/*.cpp: removed trailing .cpp from argument to
ACE_START_TEST because it would appear in the log file name
Mon Dec 2 00:08:51 1996 Douglas C. Schmidt <schmidt@lambada.cs.wustl.edu>
* ace/Log_Record.cpp (dump): There was an error on line 19 of
Log_Record.cpp:
ACE_DEBUG ((LM_DEBUG, "\npid_ = %s\n", this->pid_));
should be changed to:
ACE_DEBUG ((LM_DEBUG, "\npid_ = %d\n", this->pid_));
Thanks to Sandro Doro <alex@aureus.sublink.org> for reporting
this.
* examples/Reactor/Misc/test_handle_set.cpp: Updated the test to
remove a warning caused by sloppy nesting of loop counters.
Mon Dec 2 00:23:23 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* ace/Strategies.{h,cpp}: Update the base-class and added
documentation.
* tests/test_config.h: Added ACE_INIT_LOG, ACE_APPEND_LOG and
ACE_APPEND_LOG to facilitate the appending of log messages to a
file. Also changed Pipe_Test to use this new mechanism.
* test/Naming_Test: Changed test to use "lite" implementation to
speed things up.
* netsvcs/lib: Fixed multiple type mismatch warnings.
* ace/ReactorEx: Fixed syntax errors in recently modified
ReactorEx.* files
* ace/ace.{mdp.mak}: Added Strategies.cpp to VC++ makefile.
Sun Dec 1 19:19:02 1996 Douglas C. Schmidt <schmidt@lambada.cs.wustl.edu>
* ace/Service_Config: Moved the #inclusion of ace/Proactor.h and
ace/ReactorEx.h from the *.h file to the *.cpp file to avoid
problems with circular dependencies.
* ace/Reactor: Added a new parameter to the Reactor's
initialization methods so that we can install a subclass of
ACE_Timer_Queue. This is in anticipation of Tim's new
"real-time" implementation of a timer queue.
* ace/Reactor: Changed the internal Reactor name
ACE_Notification_Handler to ACE_Reactor_Notify to be consistent
with the ACE_ReactorEx_Notify class.
* examples/Reactor/Misc/test_demuxing.cpp: Revised this test so
that it now illustrates the new notification mechanism of the
ACE_Message_Queue class.
* examples/Reactor/Misc: Changed the name of the signal_tester.cpp
file to test_demuxing.cpp, which is really what this does.
* ace/{Strategies,Message_Queue}: Created a suite of
"Notification Strategies" that are used with the new
ACE_Message_Queue notification scheme. This works as
follows:
1. There's a new virtual hook method on ACE_Message_Queue
called notify(). Whenever a new Message_Block is
enqueued the notify() hook is called. By default, this
does nothing.
2. If you want to do something with the notify() hook, you
have two choices:
a. You can subclass from ACE_Message_Queue and
override this method. This is an example of the
"Template Method" pattern.
b. You can configure an ACE_Notification_Strategy *
into an ACE_Message_Queue. An
ACE_Notification_Strategy is the vehicle for
extending the behavior of ACE_Message_Queue wrt
notification *without subclassing*. Thus, it's an
example of the Bridge/Strategy patterns.
3. ACE_Notification_Strategy is defined in
ace/Strategies.{h,cpp}. There are two pre-defined
subclasses:
a. ACE_Reactor_Notification_Strategy -- integrates the
ACE_Message_Queue notification into the
ACE_Reactor::notify() method.
b. ACE_ReactorEx_Notification_Strategy -- integrates
the ACE_Message_Queue notification into the
ACE_ReactorEx::notify() method.
Both of these can be used almost identically in order to
seamlessly integrate multiple threads of control, inserting
ACE_Message_Blocks in one or more ACE_Message_Queues, with
the various ACE event demultiplexors (i.e., ACE_Reactor
and ACE_ReactorEx).
* ace: Created a new pair of files called Strategies_T.cpp and
Strategies_T.h and move the template ACE_*Strategies classes
into those files. This was necessary since there are now new
non-template notification strategies in Strategies.{h,cpp}.
* ace/Message_Queue: Created a new "notification hook" mechanism
that makes it possible for event demuxers (like ACE_Reactor and
ACE_ReactorEx) to be informed automatically when a Message_Block
is inserted into the Message_Queue. This is useful for
sitations where you'd like to integrate multiple threads (each
of which is pumping data into an ACE_Message_Queue) with an
ACE_Reactor or an ACE_ReactorEx. Thanks to Matthias Kerkhoff
<make@cs.tu-berlin.de> and Luca for suggesting this.
* ace/Synch.h: Modified the implementation of
ACE_Null_Condition_Mutex::wait() so that it always returns -1
and sets errno to ETIME. This reflects the fact that if you'll
never be awakened if you "sleep" on a Null_Condition...
* ace/ReactorEx: Generalized the ACE_ReactorEx so that its
notify() method now behaves like the ACE_Reactor, i.e., it can
queue up ACE_Event_Handlers that are dispatched in the ReactorEx
thread of control.
* tests: Renamed the Shared_Memory_MM_Test.cpp to
MM_Shared_Memory_Test.cpp and remove the
Shared_Memory_SV_Test.cpp since it was redundant to the
SV_Shared_Memory_Test.cpp.
* tests/SV_Shared_Memory_Test.cpp (main): Revised the SVSV IPC
shared memory test to be more robust.
* ace/SV_Semaphore_Simple.cpp (open): If the char *name == 0 then
use ACE_DEFAULT_SEM_KEY instead.
* ace/Memory_Pool: Generalized the ACE_Shared_Memory_Pool so that
there can be more than 1 shared memory pool active at a time
(similar to what we did for ACE_MMAP_Memory_Pool).
* ace/Memory_Pool.h: There was an unnecessary
ACE_SV_Semaphore_Complex in ACE_Shared_Memory_Pool that was left
over from earlier days. I've removed this.
* ace/Memory_Pool.cpp (ACE_Shared_Memory_Pool): Revised
the constructor so that if we get a NULL pool_name we'll
initialize the
* examples/Makefile: Added the System_V_IPC and Shared_Memory
directories.
* ace/Message_Queue.h: Added a virtual destructor to
ACE_Message_Queue so that it can be destroyed appropriately,
even if subclassed.
* ace/Message_Queue.h: Renamed enqueue() to enqueue_prio() to be
consistent with the other names (e.g., enqueue_head() and
enqueue_tail(). Updated the test programs to reflect this.
Sun Dec 1 12:06:46 1996 David L. Levine <levine@cs.wustl.edu>
* ace/config-vxworks*.h: Removed #define ACE_HAS_STRBUF_T:
copy and paste error
Sun Dec 1 00:15:45 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* ace/OS.h: ACE_NEW_RETURN and ACE_NEW were reverted back to the
old implementation. This is temporary till the infinite loop
problem with ACE_ERROR, ACE_DEBUG and ACE_TRACE being called
from ACE_Log_Msg::instance() is fixed.
* ace/Synch.h: Repositioned ACE_Semaphore such that there are no
problems in compiling ACE_Process_Semaphore under Win32.
* ace/config-win32-msvc4.0.h: Changed ACE_HAS_STL to
ACE_HAS_STANDARD_CPP_LIBRARY which is more descriptive (and what
is expected by stdcpp.h).
* ace/Registry.h: Added the setting of NOMINMAX and
VC_PLUS_PLUS_NESTED_CLASS_PROBLEM flags so that STL behaves
properly.
* ace/Log_Msg.cpp (open): Fixed a small bug such that msg_ostream
is only set this to cerr if it hasn't already been set.
* STL: Updated the STL directory will latest code from
http://www.rahul.net/terris/ and also added the original
readme2.stl file. Created ACE_Changes which has the list of
changes made to the STL distribution.
Sat Nov 30 12:02:00 1996 Douglas C. Schmidt <schmidt@lambada.cs.wustl.edu>
* ace/OS.h: Added a new pragma that disables warning #4097 in
MSVC++ (typedef-name used as synonym for class-name). This
keeps Win32 clients from getting warning on Win32. Thanks to
Matthias Kerkhoff <make@cs.tu-berlin.de> for this.
* ace/Log_Msg.cpp: Created a new macro called ACE_NEW_RETURN_I,
which is used withing ACE_Log_Msg::instance(). We can't afford
to call ACE_LOG_MSG->instance() from within
ACE_Log_Msg::instance() or else we will recurse infinitely!
Thanks to Irfan for finding this.
* ace/OS.i (mprotect): Added a #if !defined (ACE_LACKS_MPROTECT)
conditional compilation directive to support the EPLX real time
OS from CDC (based on LYNX). Thanks to Alexandre Karev
<karev@cern.ch> for reporting this.
Sat Nov 20 12:23:45 1996 Prashant Jain <pjain@merengue.cs.wustl.edu>
* tests/Naming_Test.cpp (main): Added code that creates a unique
backing store name and removes the backing store every time
the test is run.
Fri Nov 29 12:54:12 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Stream.cpp (open): Changed tail->close() and head->close()
to delete tail and delete head now that we've got our new
changes.
* ace/Module: Moved the destructor from the private part of the
class to the public part and changed things so that close() no
longer "deletes this." This is too confusing and error-prone.
In addition, changed the Module destructor so that it will try
to call close() only if close hasn't already been called.
* ace/Synch.h: Moved ACE_Process_Semaphore out of the
ACE_HAS_THREADS section since this is available on platforms
that don't have threads.
* Now that Log_Msg.h is being #included in OS.h, I removed all
other #includes of Log_Msg.h throughout the rest of ACE.
* ace/OS.h: Rearranged the definition of the ACE_NEW and
ACE_NEW_RETURN macros so that they come at the end of OS.h.
This enables us to #include "ace/Log_Msg.h" here, as well, so
that we can make use of the ACE_LOG_MSG macro in the definition
of ACE_NEW and ACE_NEW_RETURN.
* ace/Singleton.cpp (instance): Updated the ACE_Singleton
implementation to use the new ACE_NEW and ACE_NEW_RETURN macros.
* ace/OS.h: Revised the ACE_NEW and ACE_NEW_RETURN macros so that
they check to see if the constructor of the newly allocated
object failed (i.e., by checking the ACE_LOG_MSG->op_status()
value).
* tests/Reactors_Test.cpp: Added an ACE_ASSERT() after each
Reactor we create in order to make sure it worked.
* tests/Reactors_Test.cpp: Added an ACE_Service_Config daemon
instance within main() in order to ensure that the Reactor is
cleaned up appropriately. This avoids problems with NT 4.0,
where there seems to be a bug if you don't shut down sockets
explicitly when the process exits.
* tests/Pipe_Test.cpp (main): Improved the pipe test so that it
automatically iterates multiple times in order to test whether
there are problems with rapidly opening and closing NT socket
handles...
Thu Nov 28 03:07:48 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* netsvcs: netsvcs.mak and netsvcs.mdp were changed such that
it becomes easier to find ace.lib while compiling netsvcs.lib.
* tests/Pipe_Test.cpp: Add more instances of ACE_Pipes to the test
and also added an option to close down the pipe.
Thu Nov 28 00:53:16 1996 Douglas C. Schmidt <schmidt@lambada.cs.wustl.edu>
* ace/config-sunos4-g++.h: This config file contained two
exclusive definitions
#define ACE_HAS_SVR4_SIGNAL_T
and
#define ACE_HAS_SUNOS4_SIGNAL_T
The first one was moved out. Thanks to Alexandre Karev
<akg@na47sun05.cern.ch> for reporting this.
* ace/OS.h:
#elif defined (ACE_HAS_SUNOS4_SIGNAL_T)
was changed from
typedef void (*ACE_SignalHandler)(void);
typedef void (*ACE_SignalHandlerV)(void);
to
typedef void (*ACE_SignalHandler)(...);
typedef void (*ACE_SignalHandlerV)(...);
to make gcc happy. The first one was moved out. Thanks to
Alexandre Karev <akg@na47sun05.cern.ch> for reporting this.
* ace/Pipe.cpp (close): Arrgh! Fixed a total braino where we
weren't using ACE_OS::closesocket() to close down the Win32
ACE_Pipe implementation, which uses sockets... Thanks to Irfan
and Tilo for helping me figure this one out!
* tests/CPP_Test.cpp: Completely reworked this test so that it
should run correctly on Win32 and UNIX.
Wed Nov 27 16:50:17 1996 Douglas C. Schmidt <schmidt@lambada.cs.wustl.edu>
* Put out a new beta of ACE 4.0.33.
* tests/Mutex_Test.cpp (test): Fixed the test() function so that
it doesn't use the ACE_Thread_Control unless we explicitly want
to use threads.
* tests/test_config.h: Added addition information about the
process id and thread id of the main thread.
* ace/Synch.h: Speed things up a bit by conditionally #including
"ace/SV_Semaphore_Complex.h" only if we are compiling on a
non-Win32 platform or a POSIX platform. Thanks to Matthias
Kerkhoff <make@cs.tu-berlin.de> for this.
* ace/SV_Semaphore_Complex.h: Incorporated the new ACE_USING
macro, which is useful if you have
class b {
a()
};
class d : private b {
b::a() // still works, but depriciated
using b::a() // should be used instead
};
Thanks to Matthias Kerkhoff <make@cs.tu-berlin.de> for this.
* ace/OS.h: Added a new macro called ACE_USING, which is used to
distinguish between platforms that support namespace "using"
semantics and those that don't. Thanks to Matthias Kerkhoff
<make@cs.tu-berlin.de> for this.
* examples/Misc/test_XtReactor[12].cpp: Had to add the infamous
#define String XtString before including Xm/PushB.h. Also, there
were some references to XtReactor when the class is now
ACE_XtReactor. Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl>
for reporting this.
* ace/XtReactor.cpp (ACE_XtReactor): timeout_ was not being
initialized on the constructor, and that caused a core dump.
Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting
this.
* ace/SOCK.h: Put the open() call in the protected part of the
class since we generally don't want clients to call this
directly. Thanks to Eric Newton <ecn@clark.net> for pointing
this out.
* ace/ACE.cpp: Fixed a bug where sin.sin_family was being set
rather than sin.sin_len. Thanks to Chuck Gehr
<gehr@sweng.stortek.com> for reporting this.
* ace/ACE.cpp: Enhanced the ACE::{send_n,recv_n} methods so that
they check to see if errno == EWOULDBLOCK when ACE_OS::send() or
ACE_OS::recv() returns -1. If that's the case, then they keep
iterating.
Thanks to Mehdi TABATABAI <Mehdi.TABATABAI@ed.gva.sita.int> for
this suggestion.
* ace/Log_Msg.h: Fixed ACE_RETURN so that it only has 1 parameter
if ACE_NLOGGING is enabled. Thanks to Antonio Tortorici
<antonio@rh0011.roma.tlsoft.it> for reporting this.
* ace/config-vxworks*.h: Added ACE_NTRACE macros so that
tracing doesn't magically turn on!
* ace/Task.cpp (activate): the &ACE_Task_Base::svc_run() argument
needs a cast to ACE_THR_FUNC, because that's what
ACE_Thread_Manager::spawn_n() requires. On VxWorks,
ACE_THR_FUNC functions return an int, while svc_run() returns
void *. Thanks to David Levine for this.
* ace/Thread_Manager.cpp (kill_thr): I was mistakenly passing in
the thr_handle_ where I should have been passing in the thr_id_.
In addition, made sure we don't set errno to the wrong value...
Thanks to Ross Dargahi <rossd@acm.org> for reporting this.
* ace/{Synch_T,Synch}.h: If we don't actually own the lock
anymore, don't try to do a release. Thanks to Jonathan Biggar
<jon@sems.com> for reporting this bug.
* ace/ACE.cpp (handle_timed_complete): Added an ex_handles mask so
that non-blocking connects will work correctly on Win32. Thanks
to Antonio Tortorici <antonio@rh0011.roma.tlsoft.it> for
reporting this fix.
* ace/Message_Queue.h: Updated the documentation to stress the
fact that the timeouts are specified in *absolute* time, rather
than in relative time. Thanks to Bob Dunmire <bobd@titan.com>
for reporting this.
* tests/test_config.h: Modified the ACE_END_TEST macro so that the
log file is closed. This works around a problem on VxWorks
where destructors of static objects don't get closed
automatically. Thanks to David Levine for this fix.
* ace/OS.i (rand_r): Added a fix for Digital UNIX so that rand_r
works correctly in MT settings. Thanks to Thilo Kielmann
<kielmann@informatik.uni-siegen.de> for this.
Wed Nov 27 16:12:00 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu>
* ace/Stream.cpp: Fixed a bug in ACE_Stream::open to
allow applications to specify a tail or a head without
having to specify both. This was needed by the ACE_Pipeline
application since it only needs a Pipeline-specific tail
(not a head).
Tue Nov 26 18:00:25 1996 Douglas C. Schmidt <schmidt@lambada.cs.wustl.edu>
* ace: Functions should not be declared with ACE_INLINE in a
.cpp file. Fixed this problem in the following files:
SPIPE_Acceptor.cpp:116:ACE_INLINE
TLI_Acceptor.cpp:145:ACE_INLINE int
TLI_Acceptor.cpp:192:ACE_INLINE
Task.cpp:121:ACE_INLINE int
Task.cpp:130:ACE_INLINE void
* ace/{OS,Thread}: Added Chuck Gehr's suggested change for the
pthread_keycreate() routine, which must take extern "C"
functions on MVC C++. This fix isn't perfect, but it should
allow the ACE library to build...
* man: Updated all of the manual pages and HTML files.
* ace/Signal.cpp: Updated the code so that we don't try to
register a static C++ dispatch method if ACE_HAS_SIG_C_FUNC is
defined. This fixes problems with the MVS C++ compiler...
Thanks to Chuck Gehr for this suggestion.
* ace/OS.h: Added extern "C" { } wrappers around the signal
handling mechanisms if ACE_HAS_SIG_C_FUNC is defined. This
fixes problems with the MVS C++ compiler... Thanks to Chuck
Gehr for this suggestion.
* ace/Reactor.cpp (open): Moved the initialization of the
ACE_Timer_Queue field to *before* the handler_rep_.open() call.
We do this first in case the handler_rep_ call fails (which it
sometimes does on Win32 when we restart applications quickly due
to the use of sockets as a notification mechanism). At least
this way the timer_queue_ isn't 0, so we can still use the
Reactor as a timer... Thanks to Tilo Christ for motivating
me to fix this.
* ace/OS.i: Apparently, DIGITAL_UNIX gethostbyname() returns
thread-specific storage, so we can use this for
gethostbyname_r().
* ace/OS.i: Need to add:
#else
after line 3268: return (size_t) ACE_OS::sysconf (_SC_THREAD_STACK_MIN);
otherwise we get a compile error:
line 3296.1: CBC1331(W) Return value of type "unsigned int" is expected
This is because no code ends up getting generated. Thanks to Chuck
Gehr for this fix.
* ace/OS.i (ACE_PTHREAD_CLEANUP_PUSH): Removed an extraneous set
of parens. Thanks to Chuck Gehr for this fix.
* ace/OS.cpp (thr_create): Oops, needed to add a check if thr_id
== 0 before assigning *thr_handle = *thr_id! Thanks to Prashant
for finding this.
Tue Nov 26 21:06:13 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* ace/Pipe.cpp (open): This change relates to Win32 code only.
Removed the reuse_addr flag to acceptor.open() so that we don't
try to reuse the acceptor socket immediately. Apparently, this
causes no end of trouble on Win32 as the following connect()
call fails (randomly). Now it should be possible to create
multiple ACE_Pipes in one process and hence create multiple
Reactors also without any problems.
* tests/Pipe_Test.cpp: Added a ACE_Pipe test to check for the
creation of multiple pipes in a process. Also changed the
relevant makefiles and scripts.
Tue Nov 26 11:27:33 1996 David L. Levine <levine@cs.wustl.edu>
* tests/{CPP_Test,Mutex_Test,Shared_Memory_MM_Test,SPIPE_Test}.cpp:
added VXWORKS support for these tests by spawning a new thread
instead of forking a new process (the same as on Win32)
* netsvcs/clients/Naming/Client/Client_Test.cpp (open): Added a
return 0 for success.
* ace/Singleton.h: Modified the use of the ACE_NEW_RETURN macro so
we not only check if new has failed, but also check that the
constructor has succeeded. If it hasn't, we bail out... Thanks
to Luca for this suggestion.
* ace/Log_Msg: Added a 4th parameter to log_hexdump() in order to
print out a comment. Thanks to Luca for this.
* ace/ACE.cpp (ldfind): Changed the implementation to look for
ACE_DLL_SUFFIX rather than '.' since '.' might exist in the
pathname already...
* Removed all the NT-specific svc.conf files and updated the other
files to use the new "auto-dll-suffix" feature in ACE.
* ace/Synch_T.cpp (ts_get): Fixed a nasty bug introduced by recent
changes to ACE_TSS<>::ts_get(). The ACE_Mutex should be
ACE_Thread_Mutex. This should fix lots of nasty run-time bugs
seen with recent versions of the ACE 0.33 beta...
Tue Nov 26 14:40:00 1996 David L. Levine <levine@cs.wustl.edu>
* Log_Msg.cpp: fake out TSS on VxWorks in Log_Msg::instance()
by using a spare field in the task control block
* tests/{CPP_Test,Mutex_Test,Shared_Memory_MM_Test,SPIPE_Test}.cpp:
added VXWORKS support for these tests by spawning a new
thread instead of forking a new process (the same as on
Win32)
* OS.h: VxWorks can't handle the ACE_THR_FUNC typedef if
it's in the extern "C" block, so I moved it back out.
Also, the horrible GreenHills hack is no longer required.
* OS.i: there's an ACE_OS_CALL_RETURN before a ::strncpy() call,
I changed it to ACE_OS_CALL.
* OS.i: Added call to VxWorks ::mkdir()
* Pipe.cpp: VxWorks doesn't know about TCP_NODELAY.
* INET_Addr.cpp: get_host_name() is missing a return
statement, on VxWorks only
* Thread_Manager.i: in ACE_Thread_Control::thr_mgr(), there
were two consecutive return statements, removed the first
one.
* Time_Request_Reply.{h,cpp}: GreenHills warns that "type
qualifiers are meaningless" for declaration of const
ACE_UINT32 time(), so I removed them.
* UPIPE_Stream.cpp, line 95: warning: integer conversion
resulted in a change of sign, so we cast n to int.
* Map_Manager.cpp: in ACE_Map_Manager::resize_i(), variable
foo is unnecessary, so we omitted it.
* tests/CPP_Test.cpp (and a few others) have references to
argv[0]:
Tue Nov 26 03:15:22 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* tests: Added Map_Manager_Test and Message_Queue_Test to
makefiles (NT and UNIX) and one-button scripts.
* tests: (Barrier_Test.cpp Buffer_Stream_Test.cpp Mutex_Test.cpp
Priority_Buffer_Test.cpp Recursive_Mutex_Test.cpp
Shared_Memory_MM_Test.cpp) Fixed typos mainly and other small
changes. Also fixed logging file problems so to make logging
of tests more accurate.
Mon Nov 25 00:23:40 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* performance-tests/Synch-Benchmarks/Options.cpp (Options):
Reordered the initialization of data members to keep G++ from
complaining.
* performance-tests/Synch-Benchmarks/pipe_thr_test.cpp: Changed
some types so that we don't get warnings.
* tests/Mutex_Test.cpp (test): Added a "return 0". Thanks to
David Levine for reporting this.
* ace/TTY_IO.cpp: Rearranged some definitions so that we don't get
"unused variable" warnings from g++.
* ace/SOCK_Dgram.cpp (recv): Rearranged some definitions so that
we don't get "unused variable" warnings from g++.
* tests/Priority_Buffer_Test.cpp (consumer): Fixed a typo -- I was
missing a *... Thanks to David Levine for reporting this.
* ace/OS.h (ACE_SVC_FACTORY_DECLARE): Changed the macro so that it
defines a function with `extern "C"' linkage in order to be
consistent.
* ace/OS.cpp (thr_create): Moved the conditional compilation test
for ACE_HAS_THR_C_FUNC outside of ACE_HAS_SETKIND_NP since MVS
doesn't have this! Thanks to Chuck Gehr for this info.
* ace/OS.i (thr_sigsetmask): Replaced the tests for
ACE_HAS_DCETHREADS and ACE_HAS_SETKIND_NP with
ACE_LACKS_PTHREAD_THR_SIGSETMASK, which is more appropriate.
* ace/OS.cpp (ace_mutex_lock_cleanup_adapter): Changed the
signature so that it returns "void" rather than "void *".
Thanks to Chuck Gehr for this.
* ace/OS.h: Removed #include <sys/param.h> to avoid problems on
MVS. Thanks to Chuck Gehr for this.
* ace/config-sunos5.5-sunc++-4.1.h: It looks like SunC++ 4.1 still
doesn't fix their template typedefs bugs. So I've commented
this out in the config file. Thanks to Fred LaBar
<flabar@fallschurch.esys.com> for reporting this.
* ace/ACE.cpp (ldfind): Added support for a new feature that will
append the default suffix (e.g., ".dll" or ".so") for a shared
library on the current platform to the name of the file if it
cannot find an suffix. It will also check that a provided
suffix will match the default suffix for that platform and if it
doesn't it will produce a log entry with a warning. This change
will allow unified svc.conf-files for both UNIX and WinNT.
Thanks to Tilo Christ <christ@swl.fh-heilbronn.de> for this.
* ace/OS.cpp (thr_create): Came up with a remarkably clever scheme
that should make it possible to utilize the ACE library *without
change* on MVS, where the frigging C++ compiler requires all
functions passed to pthread_create() have an extern "C" linkage.
The trick was to generalize the thread adapter mechanism used
for Win32.
* ace/OS: Added a new macro called ACE_PTHREAD_CLEANUP_PUSH that
selects the right mechanism (e.g., ace_spawn_adapter or not) for
passing functions to pthread_cleanup_push().
* ace/config-mvs.h: Added a new macro called ACE_HAS_THR_C_FUNC
which expresses the fact that the MVS C++ compiler *must* have
an extern "C" function passed to pthread_create().
* ace/OS.h: Modified all uses of ACE_OS::mutex_lock_cleanup() to
use the extern "C" ace_spawn_adapter() on platforms MVS like MVS
that can't deal with non-C functions to pthread_create. Thanks
to Chuck Gehr for reporting this.
* ace/OS.cpp (thr_create): Added Chuck Gehr's patches for MVS.
Sun Nov 24 12:30:45 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace: Added Chuck Gehr's <gehr@sweng.stortek.com> config-mvs.h
file!
* ace: Began adding support for WinSock 2.0. Thanks to Luca for
this.
* ace/UPIPE_{Acceptor,Connector,Stream}: Updated the UPIPE
components so that they keep a reference count that keeps track
of the number of "owners" (which should always be 2 -- one for
the connector-side and one for the acceptor-side). By keeping
this count, we can ensure that we don't close down the
underlying ACE_Stream until both sides have called close().
This will remove a nasty bug that was lurking in some of the
tests.
* ace/Message_Block.h: Added a new copy() method that assumes the
buf passed in is a NUL-terminated string.
* tests/UPIPE_SAP_Test.cpp: Modified this test so that threads
exit in a well-defined order. This should prevent problems on
Win32.
* ace/OS.i: Changed SIGNAL_SAFE_OS_CALLS to
ACE_HAS_SIGNAL_SAFE_OS_CALLS to be consistent...
* ace/config-vxworks*.h: Removed the SIGNAL_SAFE_OS_CALLS #define
from the VxWorks config files. There's no need to use this by
default.
* ace/Event_Handler: Moved all the default implementations of the
virtual methods in ACE_Event_Handler from the *.i file to the
*.cpp and made them no longer be inlines. This will fix some
problems with some compilers (e.g., MSVC++ 4.1) and is also more
reasonable since there's really no purpose for inlining these
virtual functions since they are rarely called. Thanks to James
Michael Dwyer <jdwyer@knox.edu> for reporting this problem.
Sat Nov 23 12:39:03 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Svc_Conf.y: Changed the parser so that it accepts DLL
pathnames that lack *.dll or *.so suffixes. This is necessary
so that we can automatically append the correct suffix depending
on the platform. Thanks to Tilo Christ
<christ@swl.fh-heilbronn.de> for suggesting this.
* ace/Makefile: Updated the Makefile so that it will automatically
insert the appropriate so that conditions for include of
ace/OS.h can be checked correctly.
Fri Nov 22 18:12:49 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/OS.i (thr_sigsetmask): DCE threads (at least as implemented
by Digital) have no means for setting the signal mask on a
per-thread basis. Therefore, modified the code so that it
correctly returns ACE_NOTSUP_RETURN(-1) for DCEthreads. Thanks
to Thilo Kielmann <kielmann@informatik.uni-siegen.de> for
chasing this down.
* performance-tests/Synch-Benchmarks/synch_driver.cpp (run_test):
Fixed this implementation so that it will shut down correctly
when a signal occurs or a timeout occurs (whichever comes
first).
Fri Nov 22 08:02:39 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* ace.{mdp,mak}: Changed ace.mak so that it links with the
non-debug version of Microsoft's multithreaded dll when compiled
with the release option
Thu Nov 21 10:37:40 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Service_Config: Changed the implementation of the
Service_Config class so that it no longer inherits from
ACE_Event_Handler. This was causing problems because the new
reactor() method in the ACE_Event_Handler was conflicting with
the static reactor() method on ACE_Service_Config.
* ace/OS.cpp (detach): Since we no longer use an
ACE_Recursive_Thread_Mutex, we can remove the line
else if (ACE_TSS_Cleanup::lock_.get_nesting_level () > 1)
// ...
Thanks to Matthias Kerkhoff <make@cs.tu-berlin.de> for
reporting this.
* ace/Thread_Manager.cpp (spawn_n): Replaced int i with size_t i
to avoid warnings between signed and unsigned values.
* ace: There is an easy way to speed up the "Update dependencies"
in MSVC. Just keep the the compiler from complaining about
missing header by inserting a comment like below in the
#include-directives which are not used in Win32.
Therefore, instead of
#include <somefile.h>
we use
#include /**/ <somefile.h>
Please let me know if this causes problems for any
pre-processors. Thanks to Matthias Kerkhoff
<make@cs.tu-berlin.de> for this suggestion!
* ace/OS.cpp: Added support for AfxBeginThread in
ACE_OS::thr_create() and ACE_OS::exit(). Now ACE should work
with MFC when you give the THR_USE_AFX flag to
ACE_OS::thr_create()! Thanks to Matthias Kerkhoff
<make@cs.tu-berlin.de> for this!
* ace/Malloc_T.cpp (avail_chunks): Changed the return value to
ssize_t so we can return -1 if we can't get the lock. Thanks to
Tilo for reporting this.
* ace/config-sunos4-sun3.x.h: Added new #ifdefs for Sun C++ 3.0.1
on SunOS 4.1.3. Thanks to Eric Parker <eparker@credence.com>
for these fixes.
* ace/Stack.h: Added a new method called peek() to the
ACE_Unbounded_Queue classes so that the first element can be
retrieved without removing it. Thanks to Luca for this
suggestion.
* ace/SString.cpp (ACE_CString): Changed ACE_CString so that it
uses memcpy() rather than str(n)cpy() so that we can store any
structure into it. Thanks to Luca for this suggestion.
* ace/Acceptor: Since we moved the reactor() accessors to
ACE_Event_Handler we can omit these from the Acceptor and
Svc_Handler.
* ace: Updated the ACE_Reactor and ACE_ReactorEx so that they
automatically sets the pointers in ACE_Event_Handlers. Thanks
to Luca for this suggestion.
* ace/Event_Handler: Added pointers to all the ACE demultiplexors
(e.g., ACE_Reactor, ACE_ReactorEx, and ACE_Proactor) to
ACE_Event_Handler, along with set/get accessor methods. This
supports a very common use-case where an event handler keeps
track of its demultiplexor. Thanks to Luca for this suggestion.
* ace/OS.cpp: Since we do not use the recursion count from the
Recursive Mutex any more in ACE_TSS_Cleanup::exit() we can
replace the Recursive Mutex by a regular ACE_Thread_Mutex that
is recursive on NT natively and more efficient. Thanks to
Detlef for suggesting this.
* ace/OS.cpp: Since we do not use the recursion count from the
Recursive Mutex any more in ACE_TSS_Cleanup::exit() we can
replace the Recursive Mutex by a regular ACE_Thread_Mutex that
is recursive on NT natively and more efficient. Thanks to
Detlef for suggesting this.
* ace: Backed out all of Detlef's changes to ACE_OS and
ACE_TSS::ts_get(). It turns out that this is unnecessary since
he reimplemented ACE_TSS_Cleanup so that it no longer needs to
hold the lock when callbacks are made. Once again, Detlef
proves that he's a macho man, not a boy ;-)
Thu Nov 21 08:12:51 1996 David L. Levine <levine@cs.wustl.edu>
* include/makeinclude/platform_sunos5_sunc++_4.1.GNU:
put back the LD definition
* include/makeinclude/platform_osf1_4.0_g++.GNU:
added LD definition to work with latest wrapper_macros.GNU
Wed Nov 20 10:32:52 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* tests: Mutex_Test.cpp Priority_Buffer_Test.cpp
Reader_Writer_Test.cpp Thread_Pool_Test.cpp were changed
slightly to remove some compile time warnings.
Wed Nov 20 21:35:28 1996 David L. Levine <levine@cs.wustl.edu>
* ace/Svc_Conf_l.cpp: added #include of ace/config.h so that
conditions for include of ace/OS.h can be checked.
Wed Nov 20 02:38:40 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Service_Config.cpp: Moved the definition of logger_key_ to
OS.h and changed it to a macro (ACE_LOGGER_KEY) so that it will
be portable to Win32 and UNIX. Thanks to Tilo for reporting
this.
* ace/OS: Changed the return value of ACE_OS::getgid() from uid_t
to gid_t to be POSIX compliant.
* ace/OS.cpp (thr_create): Fixed a typo where we were assigning
stacksize rather than size. Thanks Thilo.
* ace/OS.cpp (thr_create): Added a new piece of code for
ACE_NEEDS_HUGE_THREAD_STACKSIZE, which is necessary to create a
larger per-thread stack size in order to run ACE_Log_Msg::log.
Thanks to Thilo for this.
* tests/TSS_Test.cpp: Changed the name of the static variable
"lock" to "cout_lock" to avoid a potential namespace clash on
Digital UNIX. Thanks to Thilo Kielmann for reporting this.
* ace/SOCK_Dgram.cpp (recv): Added a cast (char *)
io_vec->iov_base so that this would work correctly on platforms
where iov_base is a void * (e.g., AIX and HP/UX). Thanks to
Alan Stewart for the change.
* ace/OS.h: Added a few new changes for Digital UNIX 4.0a. These
should fix problems with ctime_r() and asctime_r(). Thanks to
Dave Trumble for the fixes.
* tests/UPIPE_SAP_Test.cpp: Disabled this test if we don't have
threads and (STREAM Pipes or Win32). Thanks to Thilo Kielmann's
<kielmann@informatik.uni-siegen.de> for this info.
Tue Nov 19 23:09:08 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu>
* ace/Log_Record.cpp (print): Added a call to ACE_OS::fflush
before returning. This change was suggested by Luca in order to
help prevent messages from getting lost when applications exit.
We're unsure of the affects this will have on performance, so we
may change this back in the future.
Tue Nov 19 00:06:57 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* Released a beta version of ACE 4.0.33 for testing.
* ace/TTY_IO.h: Added the ACE_Export macro before the ACE_TTY_IO
class to make things work correctly for Win32 DLLs. Thanks
to William L. Gerecke <gerecke@rayva.org> for fixing this.
* ace/OS.h: Improved the support for RLIMIT_NOFILE. Thanks to
Alan Stewart <axs2@osi.com> for reporting this.
* ace/OS.h: Removed the following code from OS.h because
it is causing problems on some platforms:
#if (!defined (timespec) && !defined (m88k))
#define timestruc_t struct timespec
#endif /* timespec */
Thanks to Fred LeBar for reporting this.
* ace/OS.cpp (thr_create): Needed to create an
ACE_OS::NULL_hthread so that we can assign the "NULL thread
handle" on POSIX platforms. Thanks to Alan Stewart
<axs2@osi.com> for reporting this.
* ace/OS.i: The HP/UX C++ compiler is unable to grok inline
functions with multiple returns. So I recoded the
ACE_OS::event* methods to avoid this. Thanks to Alan Stewart
<axs2@osi.com> for reporting this.
* ace/OS.h: Moved the "undef" of t_errno until after the inclusion
of mman.h and dlfcn.h to prevent problems with DU4.0a. Thanks
to David Trumble <trumble@steosf.nio.dec.com> for reporting
this.
* ace/Pipe.cpp (open): Fixed a typo where
this->ACE_SOCK::set_option() was being used instead of
writer.set_option(). Thanks to Tilo Christ
<christ@swl.fh-heilbronn.de> for reporting this.
* ace/Message_Queue.h: Fixed a bug where
ACE_Message_Queue <ACE_SYNCH_1> &queue_;
should be:
ACE_Message_Queue <ACE_SYNCH_2> &queue_;
Thanks to Rick Orr <rorr@costello.den.csci.csc.com> for
reporting this.
* apps/Makefile: Updated the Makefile so that it no longer tries
to look for Synch-Benchmarks. Thanks to Amos Shapira
<amos@dsi.co.il> for reporting this.
* ace/Activation_Queue.cpp (dequeue): Added a sanity check to make
sure that we actually deleted the first element in the queue.
Thanks to Andres Kruse <Andres.Kruse@cern.ch> for reporting
this.
* include/makeinclude/platform_sunos5_sunc++_4.1.GNU: Added a
minor change to remove the libACE.a archive prior to creating a
new one. This works around bugs with the SunOS 4.x C++
compiler. Thanks to Andres Kruse <Andres.Kruse@cern.ch> for
reporting this.
* ace/Malloc_T.cpp (avail_chunks): Added Fred LeBar's code and
comments for computing the available chunks.
* tests/Mutex_Test.cpp: Rewrote the Mutex_Test so that it behaves
correctly on UNIX and Win32. Thanks to Irfan for reporting the
problem.
* ace/Log_Msg.cpp (sync): Somehow, the statement that updated the
pid_ after sync() is called following a fork() got removed, so I
put it back in.
* ace/config-sunos5.*-g++.h: Added the
-D_REENTRANT flag to the config files for the G++ version of
ACE. This fixes a nasty problem that otherwise arises when
compiling on SunOS 5.x. Thanks to Hanan Herzog
<hanan@wallenda.stanford.edu> for reporting this.
Tue Nov 19 21:14:15 1996 David L. Levine <levine@cs.wustl.edu>
* performance-tests/Synch-Benchmarks/Benchmark.{h,cpp}:
use thread ID class for VxWorks as well as Pthreads.
* OS.i, config-{osf1-4.0,sunos5.[45]}-g++.h: Moved GNU
#include <cstring> out of config files and into OS.i.
* ace/Svc_Conf_l.cpp: added #include of ace/OS.h for HPUX and
VxWorks.
* ace/Token.cpp: reordered initializations in Ace_Queue_Entry
ctor to match declaration order.
Mon Nov 18 00:47:27 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/OS.h: Added a new #define called ACE_HAS_BROKEN_CONVERSIONS
to workaround problems with the HP/UX C++ compiler, which
doesn't seem to be able to grok foo->operator T *(). Thanks to
Alan Stewart <axs2@osi.com> for reporting this bug and the fix.
Also updated the config-hpux*.h files with this define.
* examples/Misc: Added a new test (test_get_opt.cpp) which
exercises the ACE_Get_Opt class.
Sun Nov 17 13:00:02 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Get_Opt: Replaced the GNU-based implementation of class
ACE_Get_Opt with an implementation based on BSD UNIX. The
advantage here is that the BSD version is not encumbered by the
GNU GPL. Thus, ACE has no more dependencies on GNU GPL. Thanks
to James Hu <jxh@cs.wustl.edu> for finding the BSD code.
Mon Nov 18 00:13:25 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu>
* ace/stdcpp.h: Added this file to ACE. This file contains the
portability ugliness for the Standard C++ Library. As
implementations of the "standard" emerge, this file will need to
be updated. Although not very useful now, we are gearing up for
a support for STL on UNIX and NT.
* ace/OS.h: Added an include "ace/stdcpp.h".
* ace/Log_Record.h (ACE_Log_Record): Removed the iostream include
mess that got accidentally committed to the release.
Sun Nov 17 00:13:25 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu>
* For some totally evil reason, MSVC++ will not allow any use of
the "allocator" symbol. It's an STL thing. As a result, I've
had to change all of the following files to rename allocator to
alloc: Local_Name_Space_T.cpp, Map_Manager.cpp, Malloc_T.cpp,
Message_Block.cpp, Read_Buffer.cpp, SString.cpp. The root
of the problem can be seen by compiling the code below:
template <class TYPE>
class foo {};
int foo; // compile error because of the foo<> class.
int main () { return 0; }
* Service_Config.{h,cpp}: We have to change the allocator
accessors to alloc. This is probably going to break
many things. If necessary, we can conditionally compile in the
old accessors for platforms that are not using STL and MSVC++.
* ace/Task.h: Added ACE_Export macros to the class definitions.
Sun Nov 17 13:00:02 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace: Added Thilo Kielmann's <kielmann@informatik.uni-siegen.de>
patches for OSF/1 4.0a.
* ace/OS: Revised the implementation of ACE_OS::asctime_r() and
ACE_OS::ctime_r() to simplify common cases. However, this may
have broken some code on OSF/1 4.0a. Can someone please check
this?
* tests/SPIPE_Test.cpp: Conditionally compiled this file so that
we only build the SPIPE test if (1) we're running on Win32 or
(2) ACE_HAS_STREAM_PIPES. Thanks to David Levine for this
suggestion.
* ace/OS.i (ctime_r): Fixed a typo that was caused by a misplaced
#endif. Thanks to Eshel Liran <liran@macs.biu.ac.il> for
reporting this.
* ace/Time_Value: Disabled ACE_TRACE within these method in order
to prevent infinite recursion.
* ace/Log_Record: Originally, when verbose mode was enabled you
can get the date and time down to the seconds. However, it is
useful for performance testings to have milliseconds displayed
in the log. To accomplish this, I changed ACE_Log_Msg and
ACE_Log_Record to they also keep track of and print the microsec
time, as well. Thanks to Luca for suggesting this.
* ace/Map_Manager.cpp: updated all the ACE_Map_Manager methods so
their read and write Guards use the ACE_*_GUARD macros.
* ace/Malloc_T.cpp: Updated all the ACE_Malloc methods so their
read and write Guards use the ACE_*_GUARD macros.
* ace/OS.cpp (svc_run): Added an ACE_DEBUG announcing that an
exception has propagated beyond the outermost svc_run()
function. Thanks to Luca for this suggestion.
* tests/test_config.h: VxWorks passes in a NULL argv (arrghhh...).
Therefore, to work around this in the ./tests directory, I changed
the ACE_START_TEST macro to take a NAME parameter, and then I
added the following local variable:
const char *program = argv ? argv[0] : NAME;
Thanks to David Levine for this fix.
Sat Nov 16 12:01:08 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* examples/Threads/test_tss2.cpp: Added Detlef's new test for
ACE_TSS.
* ace/Synch_T.cpp (ts_get): Added Detlef's changes to fix deadlock
problems with ACE_TSS on NT.
Fri Nov 15 18:01:26 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/ACE_SOCK_Stream.cpp: NT will signal an abortive close
to the opposite party if a socket is closed before all of its
data has been sent out. According to the NT SDK-docs, you should
do a shutdown before the closesocket() in order to prepare a
graceful close. Thus, I've placed an
ACE_SOCK_Stream::close_writer() method just before the call to
ACE_SOCK::close() in the new close() of the ACE_SOCK_Stream
class. Thanks to Tilo Christ <christ@swl.fh-heilbronn.de> for
this suggestion.
* ace/INET_Addr.cpp: The function ACE_INET_Addr::addr_to_string
was a virtual function that is also inline and defined in the .i
file. Some compilers have a problem with this, so I moved it
into the *.cpp file. In addition, its sister function was also
virtual and is defined as:
ACE_INLINE int
ACE_INET_Addr::string_to_addr (const char s[])
in the .cpp file. I removed the ACE_INLINE directive. Thanks
to Fred LaBar <flabar@fallschurch.esys.com> for reporting this.
Thu Nov 14 16:20:20 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Malloc_T.cpp: Added a new method to ACE_Malloc that will
return the number of chunks available on the free list. Thanks
to Fred Labar <flabar@fallschurch.esys.com> for this.
Wed Nov 13 01:22:16 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/ReactorEx.cpp (handle_events): I've changed siginfo_t on
Win32 (which was previously typedef'd to int) so that it has the
following structure:
struct siginfo_t
{
siginfo_t (ACE_HANDLE handle);
ACE_HANDLE si_handle_;
// Win32 HANDLE that has become signaled.
};
Then, I've changed the ACE_ReactorEx::handle_events() method to
look like this:
// Assign the ``signaled'' HANDLE so that callers can get
// it.
siginfo_t sig (relative_handles[relative_index]);
if (relative_handlers[relative_index]->handle_signal
(0, &sig) == -1)
Thus, you can refer to the signaled handle as
si_handle_
within the handle_signal() call back. Thanks to Matthias
Kerkhoff <make@cs.tu-berlin.de> for suggesting this.
* ace/System_Time.h: Made ACE_System_Time::get_local_time() a
static member function. Thanks to Matthias Kerkhoff
<make@cs.tu-berlin.de> for suggesting this.
* ace/Message_Queue.h: The internal variables for counting the
bytes stored in the queue were declared as of type int (in
Message_Queue.h). But they are set (e.g. with
ACE_Message_Queue::ACE_Message_Queue) with values of size_t.
When running tests/Priority_Buffer_Test, the high_water_mark_ is
preset with the value LONG_MAX. While assigning this value from
size_t to int, this becomes -1 and the queue is always believed
to be full :-( The fix is to change the internal data structures
in Message_Queue.h from int to size_t. Thanks to Thilo Kielmann
<kielmann@informatik.uni-siegen.de> for reporting this.
* tests: Fixed problems with the following three tests:
Priority_Buffer_Test.cpp
Reader_Writer_Test.cpp
UPIPE_SAP_Test.cpp
When these are compiled with gcc on Digital UNIX 4.0a the static
ACE_Thread_Manager thr_mgr; was never getting initialized due to
gcc compiler bugs. The fix is to replace the static thread
manager with the ACE_Service_Config::thr_mgr() singleton.
Thanks to Thilo Kielmann <kielmann@informatik.uni-siegen.de> for
pointing this out.
Tue Nov 12 19:43:12 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Thread_Manager.cpp (spawn_n): Was missing a 0 after ?.
Thanks to Thilo Kielmann <kielmann@informatik.uni-siegen.de> for
reporting this.
* ace/Log_Msg.h: Created a new macro call ACE_ERROR_BREAK(X) {
ACE_ERROR(X); break;} for use within switch and loop statements.
Thanks to Luca for this idea.
* ace/Pipe.cpp: Enabled the "reuse addr" flag for accepting and
connecting the Win32 version of ACE_Pipe. Thanks to Luca for
reporting this problem.
* ace/OS.i (thr_join): ACE_Thread::join () has a default second
parameter (the status) set to 0. This is not handled in
ACE_OS::thr_join(). To avoid getting a system error in NT we
handle this as we did with ACE_OS::thr_create() and the
thr_handle parameter.
* ace/config-irix6.2-sgic++.h: Updated the set of patches required
for IRIX 6.2. Thanks to Amos Shapira for reporting this.
Sun Nov 10 15:40:17 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu>
* ace/Token_Invariants.cpp: Moved static data
declarations out of ACE_Token_Invariant_Manager::instance and
into the header file. This is supposed to help with a g++
problem on VxWorks.
Sun Nov 10 13:22:03 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Pipe.cpp (open): Set the loopback socket into TCP_NODELAY
mode so that we don't block for 200 ms... Thanks to Luca
Priorelli <lucapri@mbox.vol.it>.
* ace/Thread_Manager: Created a new version of spawn_n() that
gives parameters for stack, stack_size, and also for the
assigned ACE_hthread_t's. Thanks to Thilo Kielmann
<kielmann@informatik.uni-siegen.de> for suggesting this.
Sun Nov 10 13:56:38 1996 Prashant Jain <pjain@merengue.cs.wustl.edu>
* tests/Reactors_Test.cpp (main): Fixed the test so that the
output of the test goes to a log file instead of STDOUT.
Sat Nov 9 11:23:13 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Synch.i: Fixed a bug in ACE_Thread_Mutex_Guard.
The call:
this->owner_ == block ? this->lock_.acquire () : this->lock_.tryacquire ();
should be
this->owner_ = block ? this->lock_.acquire () : this->lock_.tryacquire ();
Thanks to Alexander Smundak <sasha@migration.com> for reporting
this.
Sat Nov 9 01:44:15 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* ace/Message_Queue: Added forward and reverse iterators to
Message_Queue. Also, added typedefs to Message_Queue for
ITERATOR, and REVERSE_ITERATOR. This makes the Queue like an STL
collection and also makes it easier to use since you don't have
to define types for the iterators. Please see
test/Message_Queue_Test.cpp for an example.
* ace/Map_Manager: Added reverse iterator to Map_Manager. Also,
added typedefs to Map_Manager for ENTRY, ITERATOR, and
REVERSE_ITERATOR. This makes the Map more like an STL collection
and also makes it easier to use since you don't have to define
types for the iterators and the entry. Please see
test/Map_Manager_Test.cpp for an example. Note that the new
typedefs does not break existing code.
Fri Nov 8 20:04:26 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Malloc.h: Fixed a typo on line 176 that reads:
#include "ace/Sync_T.h"
It should read:
#include "ace/Synch_T.h"
Thanks to Todd Barkalow <todd_barkalow@stortek.com> for
reporting this.
Wed Nov 6 00:38:02 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Pipe: Added the const qualifier to the following methods:
ACE_HANDLE ACE_Pipe::read_handle (void) const;
ACE_HANDLE ACE_Pipe::write_handle (void) const;
Thanks to Luca for reporting this.
* ace/config-win32-msvc4.0.h: Redefined
ACE_LACKS_STATIC_DATA_MEMBER_TEMPLATES since it looks like
MSVC++ 4.0 still doesn't work. Maybe this is fixed in 4.2?
Tue Nov 5 03:09:44 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Strategies.cpp: I'd forgotten to update one of the
accept(*svc_handler) calls to use the new
accept(svc_handler->peer()) syntax.
* netsvcs/lib/Server_Logging_Handler.cpp: Added a cast to
(COUNTER) 0 when initializing ::request_count_ to avoid problems
on Win32. Thanks to Luca for pointing this out.
* ace/Thread_Manager: Added a new thr_self() method that return
the unique ID of the thread. This is not strictly necessary
(because a thread can always just call <ACE_Thread::thr_self>).
However, we put it here to be complete. Thanks to Hamutal Yanay
<Hamutal_Yanay@mail.icomverse.com> for suggesting this.
* ace/OS.cpp (thr_create): I was accidentally closing down
::CloseHandle (thr_handle) (where thr_handle is a HANDLE *) when
I should have been doing a ::CloseHandle (handle) instead.
Thanks to Luca for finding this!
Tue Nov 5 14:26:32 1996 David Levine <levine@cs.wustl.edu>
* include/makeinclude/wrapper_macros.GNU: Changed LINK.{c,cc}
commands to use LD instead of CXX. Changed all platform macros
files (except for g++ on VxWorks) to correspond.
* tests/run_tests.sh: changed -e test to -f for portability and
reordered tests. Thanks to Michael Michael Rueger
<m_rueger@SYSCOMP.DE> for originally creating run_tests.sh, and
for maintaining it, and to Alan Stewart <axs2@osi.com> for
suggesting fixes/enhancements.
* tests/Time_Service_Test.cpp and Tokens_Test.cpp: changed to
return 0 on success instead of 42
Fri Nov 1 03:53:39 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* STL: Added STL files to $WRAPPER_ROOT/STL. This code is a
modified version (changes for VC++ compiler) of the publicly
available implementation of STL from HP. Currently,
ACE_Registry uses these STL classes.
Fri Nov 1 00:25:01 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/CORBA_Handler.cpp (process_events): There was a very subtle
race condition in the ACE_MT_CORBA_Handler. process_events()
accessed the singleton directly without taking the mutex. At
startup the process_event thread is kicked off from the
constructor and the instance_ is set. Hence the race. The
solution is to attempt to take the mutex before accessing the
instance. Thanks to David Artus <david.artus@sbil.co.uk> for
reporting the problem and providing the fix.
* ace/Log_Msg.cpp (log): Improved the performance of the Log_Msg
mechanism by not doing any parsing of the format string if the
user has disabled this priority.
* ace/Reactor.cpp: Added a chance for the open() method of the
Notification_Pipe failing. Thanks to Luca for pointing this
out.
* ace/Reactor.cpp (handle_events): Added a change to the semantics
of the ACE_Reactor so that it doesn't fall out of the event loop
when signals arrive that it handles. Thanks to Stuart Powell
<stuartp@in.ot.com.au> for this fix.
* ace/Service_Repository.cpp (remove): Fixed a bug with
Service_Record::remove() that was failing if there were only two
records and we are removing the first one. Thanks to Alex
Villazon <villazon@cui.unige.ch> for reporting this.
* ace: Recompiled everything on Solaris with G++ and CC and it
seems to work fine.
* ace/Module: Replaced the use of char * with const char * for
assigning the Module a name.
* ace: Split the Task.{cpp,i.h} file into Task_T.{cpp,i,h} in
order to factor out the new non-template ACE_Task_Base and
ACE_Task_Exit classes. This is required for GCC-based compilers
that include the *.cpp files...
Thu Oct 31 00:36:38 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Malloc_T.h: Made the destructor of ACE_Allocator_Adapter
virtual.
* ace/Thread: Reorganized the ACE_Thread so that the
ACE_HAS_THREADS #ifdef is no longer required...
* ace/Strategies.h: Changed all the destructors to be virtual so
that G++ will stop complaining...
* ace/Thread_Manager: Reorganized the ACE_Thread_Manager so that
the ACE_HAS_THREADS #ifdef is no longer required...
* ace/config-win32-msvc4.0.h: Added Dieter Quehl's great hack to
get ACE to compile correctly on Win32 with MFC!
* ace/Task: I've rearranged the implementation of ACE_Task<>
in the following way:
1. Defined a non-template class ACE_Task_Base from which the
ACE_Task<...> inherits (instead of inheriting from
Ace_Service_Object, which ACE_Task_Base now inherits from.
2. Move all methods that don't depend on the <ACE_MT_SYNCH> or
<ACE_NULL_SYNCH> modifers from the ACE_Task template to
ACE_Task_Base.
There are two motivations for making this change:
1. It reduces ``template bloat'' by factoring out common
code that can be shared between ACE_Task<ACE_MT_SYNCH>
and ACE_Task<ACE_NULL_SYNCH>.
2. It makes it possible for the Thread_Manager to use
ACE_Task_Base *'s for managing groups of ACE_Tasks
in a fully polymorphic manner.
Note that the new changes don't break any existing code that
uses ACE_Task. Thanks to Hamutal Yanay
<Hamutal_Yanay@hub.comverse.com> and Ari Erev's
<Ari_Erev@comverse.com> for suggesting these changes.
* ace/Thread_Manager: Changed the use of ACE_Task<ACE_SYNCH> to
ACE_Service_Object because this avoids nasty problems with
template type conflicts. The right solution is probably to
create a new non-template base class for ACE_Task called
ACE_Task_Base and move all the ACE_Task operations into there
that don't involve the Message_Queue directly. I'll need to
think more about this...
* ace/SOCK_Stream: Added new timed send_n() and recv_n() methods,
which use the underlying timed ACE::send() and ACE::recv()
calls.
* ace/ACE.cpp: Added new timed send_n() and recv_n() methods,
which use the underlying timed ACE::send() and ACE::recv()
calls.
Wed Oct 30 00:27:21 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/OS.h: Changed MAXHOSTNAMELEN on Win32 from
(MAX_COMPUTERNAME_LENGTH+1) (which is around 16 or so) to 256.
Thanks to Tilo Christ <christ@swl.fh-heilbronn.de> for this
suggestion.
* ace: Made #define STRICT a compile time option if the
ACE_HAS_STRICT flag is enabled. This prevents ACE from breaking
existing application (i.e., non-ACE) code. Thanks to Karlheinz
for pointing this out!
* ace/Synch_T.cpp: Fixed a typo in ACE_Condition<MUTEX>::wait
(void).
return ACE_OS::cond_wait (&this->cond_, this->mutex_.lock_);
should read
return ACE_OS::cond_wait (&this->cond_, &this->mutex_.lock_);
Thanks to Dieter Quehl <dietrich.quehl@med.siemens.de> for
reporting this!
* ace/Svc_Handler.h: Removed the operator ACE_PEER_STREAM &() from
the ACE_Svc_Handler class since we don't need it anymore due to
the changes below.
* ace/{Acceptor,Connector}.cpp: Removed the use of operator
ACE_PEER_STREAM &() in the Acceptor::accept() and
Connector::connect() code and replaced it with
svc_handler->peer(). This works much better and is more
intuitive.
Wed Oct 30 00:30:00 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* Registry: Added a Name Service implementation to ACE based on
Win32 Registry. The ACE_Registry interface is inspired by the
interface specified in the CORBA Naming Service Specification.
The implementation is done through Win32 Reg*() functions.
Other than providing an OO wrapper for the Win32 Reg*()
functions, ACE_Registry provides an abstraction for iteration
over the elements of the Registry. This only works on Win32
platforms (unless you are brave enough to reimplement the
Win32 Registry API on UNIX and link it in underneath ACE!).
* ace/Local_Name_Space_T.cpp: Moved SEH out of methods of
Name_Space_Map to the methods of Local_Name_Space. Some of
the calls to Local_Name_Space methods used the allocator to
either malloc or find or free shared memory. Adding SEH to these
methods ensured that any exception raised due to remapping would
be caught and handled appropriately.
Also, to fool the stupid MFC compiler, we added _i methods
so that it stopped bitching about destructors not getting called
correctly.
* Added three new tests to /examples/Naming. Thanks to Lothar for
providing these tests.
Tue Oct 29 18:10:09 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/ACE.cpp (send): Integrated a new and simpler version of
timed ACE::send(). Thanks to Vital Aza <va3@cs.wustl.edu> for
coming up with this.
* ace/XtReactor.cpp: When the ACE_Reactor is constructed it
creates the notify pipe and registers it with the attach()
method. The XtReactor overloads this method BUT because the
attach occurs when constructing the base class ACE_Reactor, the
ACE_Reactor attach() is called not the XtReactor attach(). This
means that the notify pipe is registered with the ACE_Reactor
event handling code not the XtReactor and so notfications don't
work. To get around this we simply close and re-opened the
notification handler in the constructor of the XtReactor.
Thanks to Rodney Skinner <rods@in.ot.com.au> for this fix.
* ace/XtReactor.cpp (schedule_timer): The ACE_Reactor returns a
timer_id from it's equivalent call but the XtReactor always
returns 0. To fix this we simply replaced the "return 0;" in
the function with "return result;" Thanks to Rodney Skinner
<rods@in.ot.com.au> for reporting this.
Tue Oct 29 00:02:44 1996 Douglas C. Schmidt <schmidt@lambada.cs.wustl.edu>
* ace/config-win32-msvc4.0.h: Defined the STRICT symbol based on a
suggestion from Luca. STRICT type checking in WINDOWS.H
enhances type safety for Windows programs by using distinct
types to represent all the different HANDLES in Windows. So for
example, STRICT prevents you from mistakenly passing an HPEN to
a routine expecting an HBITMAP. Note that if you have STRICT
type checking enabled in one file, but not in another, the C++
compiler will generate different external link symbols for a
single function. This will result in link-time errors If you are
mixing STRICT and non-STRICT code, you must be aware of linkage
inconsistencies. In general, all MFC programming and all C++
should be done with STRICT. If you have legacy C code, then not
using STRICT is acceptable
* ace/OS.cpp (thr_create): Added a special check for the situation
where we have both ACE_HAS_PTHREADS and ACE_HAS_STHREADS
defined. In this case, we are running on Solaris, where
ACE_thread_t and ACE_hthread_t are the same. Therefore, we can
copy the value of the *thr_id into the *thr_handle. This
ensures that the ACE_Thread_Manager behaves correctly with
respect to suspending and resuming threads and ACE_Tasks.
* ace/Trace.cpp (ACE_Trace): Changed the use of LM_DEBUG to
LM_TRACE in the constructor and destructor. Thanks to Luca for
this!
* ace/OS.i: Added a cast to of (HMODULE) handle so that the STRICT
macro would work correctly for Win32. Thanks to Luca for this.
* ace/config-win32-msvc4.0.h: According to Luca, ACE compiles file
with ACE_LACKS_STATIC_DATA_MEMBER_TEMPLATES undefined on NT. So
I undefined it! If there are any problems with this, please let
me know.
* ace/SOCK_Dgram: Added Luca Priorelli <lucapri@mbox.vol.it>
implementation of recv() for SOCK Dgrams that allows clients to
read from a socket without having to provide a buffer to read.
* examples/Threads/test_task_four.cpp: This is a new test
program to test the new interfaces. Thanks to Hamutal Yanay
& Ari Erev for this.
* tests/test_config.h: Added a call to the new ACE_OS::mkdir()
wrapper to create the log directory if one doesn't already
exist. This should solve some nasty problems with NT reported
by Tilo Christ <christ@swl.fh-heilbronn.de>.
* ace/OS.h: Added a new macro ACE_DEFAULT_DIR_PERMS and changed
the spelling of the existing ACE_DEFAULT_PERMS to
ACE_DEFAULT_FILE_PERMS, which is more accurate.
Mon Oct 28 21:35:12 1996 Douglas C. Schmidt <schmidt@lambada.cs.wustl.edu>
* ace/OS.h: Added a wrapper for the mkdir() system call. We need
it for some of the tests.
* ace/Task: Changed the name of ACE_Task_Exit<>::set_this() to
ACE_Task_Exit<>::set_task(). Thanks to Hamutal Yanay & Ari Erev
for suggesting this.
* ace/{Task,Thread_Manager}: Integrated Hamutal
<Hamutal_Yanay@hub.comverse.com> Yanay & Ari Erev's
<Ari_Erev@comverse.com> enhancements to add ACE_Task support
to the ACE_Thread_Manager. This allows the ACE_Thread_Manager to
know about ACE_Tasks directly, rather than knowing
indirectly via their lower-level thread IDs. The changes
are described below:
- Added a parameter to the activate() method. It is used to
pass an ACE_Task* to spawn_n().
- Modified suspend() and resume() to call
thrMgr->suspend_task() and thrMgr->resume_task() instead of
thrMgr->suspend_grp() and thrMgr->resume_grp().
- Added an ACE_Task * parameter to spawn_n().
- Added an ACE_Task * parameter to append_thr().
- append_thr() uses the ACE_Task * input parameter to
initialize the thread descriptor.
- Added the following methods:
apply_task()
suspend_task()
resume_task()
kill_task()
resume_task()
cancel_task()
find_task()
num_tasks_in_group()
num_threads_in_tasks()
task_list()
thread_list()
hthread_list()
set_grp() Like the current set_grp() but gets an ACE_Task *
as input.
get_grp() Like the current set_grp() but outputs an
ACE_Task *.
wait_task()
wait_group()
Sun Oct 27 11:25:00 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/OS: modified the ACE_OSCALL_RETURN macro so that we'll
no longer have zillions of warnings about _result not
used...
* ace/Synch_T: Changed the use of ACE_Mutex for ACE_TSS to
ACE_Thread_Mutex.
* ace: Added the necessary template specializations to get ACE
compiled correctly with G++.
* ace/Log_Msg.h: There were some places in the ACE_{DEBUG,ERROR}
macros that should have been using __ace_error but there still
using errno (which is wrong since this might be changed due to
side-effects of calling ACE_Log_Msg::instance()). I found this
problem due to the use of -Wall with G++! As a result of this
fix, ACE now compiles much more cleanly with gcc -Wall.
* ace/Strategy: Improved the scheme used to define the PEER_ADDR
type of the ACE_Accept_Strategy so that it will work correctly
on platforms whose C++ compilers aren't quite up to handling all
variants of template typedefs. In particular, many platforms
don't support the use of template typedefs in parameter names...
* ace/OS: HP/UX omitted the const in the prototype of
const_timewait(). Therefore, I added a new typedef to handle
this and updated all the HP/UX config*.h files.
* ace: Added a new config file (config-sunos5.5-sunc++-4.1.h)
which reflects the fact that SunC++ 4.1 fixes template bugs that
prevented earlier versions from supporting template typedefs
correctly. The new config file #defines
ACE_HAS_TEMPLATE_TYPEDEFS.
Sat Oct 26 02:22:25 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace: On the advice of David Levine, I compiled ACE with gcc
-Wall and started to fix lots of minor warnings (e.g.,
misordered data member initializations).
* ace/Local_Tokens.h: Changed the destructors of ACE_Mutex_Token,
ACE_RW_Token, ACE_Token_Proxy, and ACE_RW_Token to be virtual.
* ace/Synch_T.h: Changed the destructor of ACE_TSS to be virtual.
* ace/OS: Changed the prototype of ACE_OS::select() so that it
uses const ACE_Time_Value *.
* Updated all uses of ACE_Malloc to use the new ACE_*_MEMORY_POOL
#defines. This makes it possible to use the ACE_Malloc<> scheme
with lame C++ compilers.
* ace/ACE: Changed the interface of the new timed send/recv calls
to use ACE_Time_Value *, which makes it easier to determine
the blocking semantics at runtime. Thanks to Bill Fulton
<bill@fasttrack2.bscc.bls.com> for suggesting this.
Sat Oct 26 15:55:02 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* ace/OS.h: We determined that MSVC++ is capable of supporting
template typedefs. Therefore, we can enable the
ACE_HAS_TEMPLATE_TYPEDEFS flag, which makes life much easier for
end users!
Fri Oct 25 23:16:16 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* examples/Shared_Malloc/test_multiple_mallocs.cpp: Added a new
test that demonstrates the new ability of ACE_Malloc<> to to
handle multiple mallocs rooted at different base addresses.
* ace/Memory_Pool: Fixed this stuff so that it works even when C++
compilers can't grok template typedefs.
* ace: Put all the macros that handle the fact that many C++
compilers have broken template implementations into one place
(OS.h), rather than having this spread out in many files.
* In ACE_MMAP_Memory_Pool::init_acquire (), we reset errno to 0 in
the case where the file already exists (and errno == EEXIST).
* Added an ACE_*_Memory_Pool_Options class to each Memory Pool
class. The Options class allows detailed parameters to be passed
to the constructor of the Memory Pool class. Since a typedef'd
Options class was added to every Memory Pool class, this gave us
the ability to use traits in ACE_Malloc and
ACE_Allocator_Adapter to construct generic Memory Pools that can
be initialized uniquely for each instance of ACE_Malloc. Note
that this new feature only works for C++ compilers that support
template typedefs correctly (e.g., MSVC++ 4.x, SunC++ 4.1,
and the AIX C++ compiler).
* Added additional constructors to ACE_Malloc and
ACE_Allocator_Adapter to allow Options to be passed in to Memory
Pool.
* Added an extra field in ACE_Name_Options which allows
specification of the base address of the memory pool. This is
now used by ACE_Local_Name_Space::create_manager() to create an
ACE_Allocator_Adapter. This now allows us to have multiple
ACE_Naming_Context simultaneously in the same process address
space.
* Also added error checking for constructors (in
ACE_Local_Name_Space and ACE_Malloc) by checking errno
values. This is a "hack" since we currently do not use exception
handling.
Thu Oct 24 02:43:11 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* examples/Connection/misc/Makefile: The Makefile in
ACE_wrappers/examples/Connection/misc seems to have been
truncated. I replaced it. Thanks to Alan Stewart
<axs2@osi.com> for reporting this.
* examples/IPC_SAP/SOCK_SAP/CPP-{inclient,inserver}.cpp: Updated
these examples to use the new timed send()/recv() operations.
* ace/SOCK_IO: Added timed send()/recv() methods, using the base
level implementations in class ACE.
* ace/ACE: Added timed send()/recv() methods.
Wed Oct 23 19:56:45 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* examples/IPC_SAP/SOCK_SAP/CPP-inclient.cpp (main): Changed the
behavior of the test program so that it doesn't take a
local_addr, but rather will use the default (this prevents a
common problem that happens when users run the test without
reading the README file).
* ace/ACE.cpp: Added a new method (get_flags) that returns the
current setting of flags associated with handle.
* Start of a brave new world: ACE is now under CVS version
control... Thanks to David Levine and Chris Cleeland
for making this happen.
Sat Oct 19 12:33:56 1996 David L. Levine <levine@cs.wustl.edu>
* added ACE threads mappings to VxWorks 5.2 tasks in OS.*.
NOTE: this is _untested_ at this point, but only affects
VxWorks code
* changed name of first argument of ACE_OS::sigprocmask() and
ACE_OS::thr_sigsetmask() from "signum" to "how" to better
represent what it really is.
Wed Oct 16 01:59:40 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Log_Record.cpp (print): added Luca's suggestion for checking
if host_name == 0 for the ostream version of print(), as well.
* Released version of ACE 4.0.32 for testing.
* ace/Synch.h: Added many small fixes for HP/UX 10.x. Thanks to
Alan Stewart <axs2@osi.com> for providing these.
* ace/OS.h: Added many new ACE_LACKS* and ACE_HAS* macros to
support the MVS port. Thanks to Chuck Gehr
<gehr@sweng.stortek.com> for these.
Tue Oct 15 11:56:59 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/OS.h: in a continuing effort to protect the ACE namespace,
I've changed ace/OS.h around lines 127-137 so that "SYNCH" and
"SYNCH_MUTEX", etc. are prefixed with "ACE_". Thanks to Alan
Stewart <axs2@osi.com> for suggesting this.
* ace/Local_Tokens.h: Removed an unnecessary parameter name
that was unused. Thanks to Stuart Powell <stuartp@in.ot.com.au>
for reporting this.
Tue Oct 15 17:03:37 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu>
* ace/ReactorEx.cpp (handle_events): Fixed a bug in handle_events
so that the correct handlers get called when multiple handles
become signaled simultaneously. Thanks to Ari Erev
<Ari_Erev@comverse.com> for pointing out this bug. I also took
this opportunity to fix a bug when handlers are removed during
handle_events.
* examples/Reactor/ReactorEx/test_remove_handler.cpp: Added a new
application that tests how the ReactorEx services simultaneous
events and removes handlers. This example also illustrates the
use of the new ACE_Events wrapper. Check
examples/Reactor/ReactorEx/README for more details.
Mon Oct 14 11:43:18 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* tests: Added a new version of run_tests.sh, which was
contributed by Michael Rueger <mike@SYSCOMP.DE>.
* examples/Logger/simple-server/Logging_Handler.cpp (handle_input)
and examples/Logger/Acceptor-server/server_loggerd.cpp
(handle_input): Changed from stderr to cerr to work around bugs
with the C run-time libraries on Win32. Thanks to Tilo Christ
<christ@swl.fh-heilbronn.de> for suggesting this.
Mon Oct 14 11:09:42 1996 Prashant Jain <pjain@merengue.cs.wustl.edu>
* ace/Local_Name_Space_T.cpp (remap): Added processor specific
stuff to remap(). The code was taken from the book "Win32
Network Programming" by Ralph Davis (p.18) and takes care of
cases specific to the 80x86 processor. The code ensures that the
registers are set properly when we continue execution after an
exception.
Sun Oct 13 21:18:38 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Log_Record.cpp (print): Added a test to make sure that the
value returned from ctime_r != 0 (e.g., if time_stamp_ == -1) in
order to avoid crashes.
* examples/Logger/client/logging_app.cpp (main): Moved the
construction of the ACE_Log_Record log_record object into the
loop so that it will be recreated each time through. If this
isn't done, then we'll be continually "encoding" values into
network byte order that have already been encoded and screwing
things up on little-endian machines (such as Intel). Thanks to
Irfan and Tilo Christ <christ@swl.fh-heilbronn.de> for pointing
me in the right direction on this.
* ace/Log_Record.cpp: Changed the default constructor so that it
gives default initializations to the data members.
* examples/Logger/Acceptor-server/server_loggerd.cpp (handle_input):
Fixed a couple of typos where
Logging_Handler::handle_input (int)
should be:
Logging_Handler::handle_input (ACE_HANDLE)
and
size_t len;
should be:
ssize_t len;
Thanks to Irfan for finding these.
Sat Oct 12 08:48:23 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* Released a beta version of ACE 4.0.32 for testing.
* ace/Log_Record.cpp: rewrote the code a bit to try and avoid
problems on NT when host_name == 0.
* ace/Log_Record.cpp: Changed the use of ACE_OS::ctime() to
ACE_OS::ctime_r() to avoid problems that might arise when
ACE_Log_Record::print() is called from multiple threads.
* ace/Log_Record.cpp: Commented out calls to ACE_TRACE to avoid
weird problems with circular dependencies. Thanks to Luca
Priorelli <lucapri@mbox.vol.it> for suggesting this.
* build/SunOS5.5/examples/Makefile: Added the Logger directory to
the list of targets that are build automatically by Make.
Fri Oct 11 17:13:03 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace: Fixed lots of small warnings revealed when using the
Greenhills compiler on VxWorks. Thanks to David Levine for
this.
* ace/Pipe.h: In Pipe.h, the return value of ACE_Pipe::close()
isn't explicitly declared, so some compilers gag. Thanks to
David Levine for this.
Thu Oct 10 12:05:55 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Thread.cpp: Correctly wrapped the methods in the *.cpp file
so that they are ignored if threads *aren't* supported.
* ace/Service_Repository.cpp (remove): Added the ACE_MT in front
of all the ACE_GUARD* macros that utilize ACE_Thread* locks in
order to ensure that ACE compiles correctly on all non-MT
platforms.
* examples/Shared_Malloc/Malloc.cpp: Removed the special purpose
class for PROCESS_MUTEX since ACE_Process_Mutex will now work
for non-MT platforms.
* examples/Misc/test_dump.cpp: Changed all occurrences of
cerr << "string " << this << endl;
to
cerr << "string " << (u_long) this << endl;
to work around problems with IRIX 5.3. Thanks to Tilo Christ
<christ@swl.fh-heilbronn.de> for reporting this.
* ace/config-linux.h: Added a // in front of a stray comment line.
Thanks to Neil Cohen for pointing this out.
* ace/config-hpux-10.x-g++.h: Added a new config file for HP/UX
10.x which should fix some problems with templates by using the
G++ compiler. Thanks to <afarahat@CCGATE.HAC.COM> for
contributing this.
Wed Oct 9 14:34:19 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/OS: Changed the logic of socket initialization, which has
been moved out of ACE_SOCK and into ACE_OS. This makes it
possible to program more fully at the ACE_OS API (if such a
crazy thing is really necessary ;-)).
* examples/IPC_SAP/SOCK_SAP/C-in{client,server}.cpp: Fixed up the
client and server apps so they will work on NT
(i.e., replaced the use of int with ACE_HANDLE). Thanks to Joe
DeAngelis <bytor@faxint.com> for suggesting this.
* ace/Synch.h: Now that we've got support for POSIX semaphores on
Solaris, then we'll use them (when they are supported...) as the
implementation of ACE_Process_Semaphore rather than using the
slower ACE_SV_Semaphore_Complex stuff...
* ace/OS.{h,i}: Added David Levine's support for named POSIX
semaphores. If ACE_HAS_POSIX_SEM is defined, then ACE_Semaphore
will construct a named POSIX semaphore if passed a non-null
name, or an unamed POSIX semaphore if passed a null name. This
is a great addition because POSIX semaphores are more powerful
and useful than the Solaris UI semaphores. Unfortunately,
Solaris 2.5 doesn't support them (yet).
Tue Oct 8 16:00:00 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu>
* ace/OS: Integrated Irfan's encapsulation/emulation for Win32
Events at the ACE_OS level. A new structure ACE_event_t was
created to support Events on non-WIN32 platforms. On WIN32
platforms ACE_event_t is just a HANDLE. On non-WIN32 platforms,
ACE_event_t uses a combination of mutexes, condition variables,
and counters to emulate Events. Both auto-reset and manual-reset
events are supported.
* ace/Synch: Integrated Irfan's encapsulation/emulation for Win32
Events at the C++ wrappers level. There are three wrappers that
were created: ACE_Event, ACE_Auto_Event, and ACE_Manual_Event.
ACE_Event is a wrapper for the ACE_event_t structure. It
provides functionality for signal, wait, pulse, and reset on an
event. ACE_Event supports both auto-reset and manual-reset
events. However, specializations of ACE_Event were created
(ACE_Manual_Event and ACE_Auto_Event) to make it easier to use
Events.
* examples/Threads/test_manual_event.cpp: A test for manual-reset
events. The test involves the creation and use of a barrier
which uses an ACE_Manual_Event.
* examples/Threads/test_auto_event.cpp: A test for auto-reset
events. The test involves the use of an ACE_Auto_Event for
signaling threads.
Tue Oct 8 15:45:01 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/DEV.cpp (ACE_DEV): Removed a stray call to
ACE_IO_SAP::dump(). Thanks to Brad Flood <BFLOOD@tcs.lmco.com>
for this fix.
* ace/OS.i: Added ACE_HAS_CHARPTR_SOCKOPT for VxWorks. Thanks to
David Levine for this.
* ace/Dump.cpp (instance): Added an ACE_MT() macro around the
ACE_GUARD_RETURN macro so that this will compile correctly on
non-threaded platforms. Thanks to David Levine for this.
* ace/OS.h: the declaration of ACE_OS::msgctl needs "struct
msqid_ds" instead of just "msqid_ds" to compile with the
Greenhills C++ compiler. Thanks to David Levine for this...
* ace/Local_Name_Space_T.h: Added #include "ace/Local_Name_Space.h"
to avoid a problem during template generation. Thanks to
Chris Lahey for this fix.
* ace/OS.i (getprotobynumber_r): Added a pair of fixes from Chris
Lahey to get the ACE wrappers for the getprotoby*_r() methods to
compile on AIX.
* examples/Threads: Added two new examples (test_auto_event.cpp
and test_manual_event.cpp) that exercise the new ACE_Event
mechanisms.
* ace/Synch: Integrated Irfan's encapsulation/emulation for Win32
Events at the C++ wrappers level.
* ace/OS: Integrated Irfan's encapsulation/emulation for Win32
Events at the ACE_OS level.
Fri Oct 4 08:32:47 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/OS.i: Added David Levine's new ACE_OS::mktemp() implementation.
Wed Oct 2 13:26:20 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/SV_Message_Queue.i: Changed the casts of (msgbuf *) to
(void *).
* ace/OS.i: Added David Levine's implementation of inet_addr() for
VxWorks.
* ace/OS.i: Continued to merge together various parts of Win32 and
UNIX to reduce redundancies.
Tue Oct 1 15:03:42 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/OS.i: Added Chuck Gehr's new changes to ACE_OS::mutex_init()
and ACE_OS::cond_init() to handle the MVS Pthreads madness.
* ace/OS.i: Added zillions of #ifdefs for VXWORKS. It's amazing
these guys call themselves POSIX compliant -- lots of stuff is
missing. Thanks to David Levine for doing this!
* ace/OS.cpp: Added David Levine's implementation of mktemp()
for platforms that don't support it.
* ace/OS.h: Added a bunch of minor changes for VXWORKS. In
addition, started to factor out common #ifdefs to make the code
easier to maintain.
* ace/OS.h: Added a new macro for ACE_LACKS_UTSNAME, and factored
this out for both VxWorks and Win32.
* ace/Time_Value.h: Added support for 2 VXWORKSisms: (1) we need
to #include sys/times.h rather than the standard UNIX sys/time.h
and (2) we need to change const timeval & to const struct
timeval & to keep the Greenhills compiler happy. Thanks to
David Levine for this.
* ace/INET_Addr.cpp: Added support for the insane VXWORKS
hostGetByName() function. Yikes! Thanks to David Levine for
this.
* ace/Memory_Pool.cpp: Added a new #define called ACE_LACKS_SBRK
and ACE_LACKS_SYSV_SHMEM, which is enabled on Win32 and VxWorks.
Thanks to David Levine for reporting this.
* ace/OS.h: Added new macros that #define ETIME for platforms like
VxWorks that don't support it, but do support ETIMEDOUT.
* ace/OS.h: Added placeholder #defines for USYNC_PROCESS and
USYNC_THREAD when !defined (ACE_HAS_THREADS). Thanks to Neil
Cohen for reporting this.
Tue Oct 1 00:42:35 1996 Douglas C. Schmidt <schmidt@polka.cs.wustl.edu>
* ace/Message_Block.cpp (size): Member base_ of ACE_Message_Block
was being set to the new memory pointer before the old contents
are saved in method size. So the line
this->base_ = buf;
was moved to a place some lines below. Thanks to Marco Sommerau
<sommerau@informatik.uni-stuttgart.de> for detecting this.
* ace/Message_Queue.cpp: Changed the implementation of the
enqueue_i() method so that FIFO order is maintained when
messages of the same priority are inserted consecutively.
Thanks to Jay Denkberg <jay_denkberg@comverse.com> for
suggesting this.
Mon Sep 30 22:59:38 1996 Douglas C. Schmidt <schmidt@polka.cs.wustl.edu>
* ace/OS.i (thr_yield): Added a new macro ACE_HAS_YIELD_VOID_PTR
to make pthread_yield work on MVS. Thanks to Chuck Gehr
<gehr@sweng.stortek.com> for this fix.
* ace/OS: Added a new macro called ACE_HAS_TIMEZONE_GETTIMEOFDAY
that handles problems on MVS. Thanks to Chuck Gehr
<gehr@sweng.stortek.com> for this fix.
Mon Sep 30 13:45:10 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu>
* ace/Local_Tokens.h: Updated some documentation in all the Token
files.
Mon Sep 30 18:01:12 1996 Prashant Jain <pjain@merengue.cs.wustl.edu>
* netsvcs/lib/: Renamed files Logger.{h,cpp} to
Logging_Strategy.{h,cpp} to avoid confusion with Server_Logging
and Client_Logging stuff. In addition, I modified the affected
files, including Makefile, README, and the config files in the
tests directory.
Sun Sep 29 12:47:37 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/OS.h: Added Chuck Gehr <gehr@sweng.stortek.com> fixes for
MVS to enable signals to work correctly.
* ace/Time_Value.h: Added an extern "C" { } block around #include
<pthreads.h> to solve a problem with Linux. Thanks to Padhu
Ramalingam <padhu@magicnet.net> for reporting this.
* netsvcs/lib/Server_Logging_Handler.cpp: Changed the
initialization of a static template object from ::request_count_
(0L) to ::request_count_ = 0L. Thanks to Gonzalo Diethelm
<gonzo@ing.puc.cl> for reporting this.
* ace/Remote_Tokens.h: Moved the inclusion of "Singleton.h" from
Remote_Tokens.cpp to Remote_Tokens.h. This should avoid
template instantiation problems on some platforms (e.g., Irix
6.2).
* ace/config-irix6.2-sgic++.h: Changed ACE_HAS_SIGINFO to
ACE_HAS_SIGINFO_T and added ACE_HAS_UCONTEXT_T. Thanks to
Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting this.
* ace/Token_Invariants.h: The ctor/dtor were private and the
compiler would not allow a template of the class to be created.
I switched them to public, but I wish there was a better way...
Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting
this.
* ace/Synch_T.h: #include'd "ace/Event_Handler.h". Thanks to
Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting this.
* ace/Synch.h: The parameter name gives warnings when
instantiating templates. Thanks to Gonzalo Diethelm
<gonzo@ing.puc.cl> for reporting this.
* ace/Process: Changed the definition of the get_pid() method to
getpid() to avoid a conflict with Irix. Thanks to Gonzalo
Diethelm <gonzo@ing.puc.cl> for reporting this.
* ace/Log_Msg.cpp (log): Added another #elif !defined (ACE_WIN32)
to handle logging for OS platforms that (1) aren't Win32 and (2)
are versions of UNIX that don't support STREAM pipes. Thanks to
Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting this.
* ace/Acceptor.cpp (handle_signal): Erased the signum parameter
name to avoid a nasty warning about arguments not used when
instantiating templates. Thanks to Gonzalo Diethelm
<gonzo@ing.puc.cl> for reporting this.
* ace/OS.h: Added the ACE_Export symbol to the definition of
ACE_Str_Buf. This makes it compile and link on NT. Thanks to
Prashant for noticing this (our favorite Win32ism...).
* ace/Thread.h (ACE_Thread): Removed a default argument for one of
the ACE_Thread::join() wrappers so this won't be ambiguous with
the other join() wrapper.
* ace/OS: Added a new wrapper for strtok_r().
Sun Sep 29 16:12:01 1996 Prashant Jain <pjain@merengue.cs.wustl.edu>
* netsvcs/lib/: Renamed the project file for Win32 from lib.mdp to
netsvcs.mdp. Also the original project file did not include some
files such as Naming_Handler.cpp and Server_Logging_Handler.cpp
and I fixed that. Finally removed two files System_Time.{h,cpp}
which are already present in ace/.
Sat Sep 28 16:34:56 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/OS: Added a new overloaded select() method that takes a
const ACE_Time_Value &. This is useful for situations where you
are passing in ACE_Time_Value::zero.
Fri Sep 27 16:20:46 1996 Douglas C. Schmidt <schmidt@polka.cs.wustl.edu>
* ace/ACE: Added a fix for the fact that VxWork's write() call
doesn't take a const char *.
* ace: Started adding support for VxWorks and GreenHills compiler,
e.g., added the config-vxwork-ghs-1.8.h file. Thanks to David
Levine <levine@cs.wustl.edu> for getting this rolling!
Thu Sep 26 00:15:46 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Timer_Queue: Changed the public interface methods to be
virtual in order to make it possible to override them in
subclasses. This makes it feasible to implement different types
of Timers.
* ace/OS: Added a wrapper for the strspn() string call. Thanks to
Irfan for noticing this omission.
* ace/Synch_T.cpp (wait): Changed the line:
return ACE_OS::cond_wait (&this->cond_, this->mutex_);
to
return ACE_OS::cond_wait (&this->cond_, &this->mutex_.lock_);
Thanks to Dieter Quehl <dietrich.quehl@med-iss1.med.siemens.de>
for noticing this.
* ace/config-sunos5.4-g++.h: Removed the #define for
ACE_HAS_BROKEN_RANDR and replaced the ACE_HAS_SVR4_SIGNAL_T with
ACE_HAS_CONSISTENT_SIGNAL_PROTOTYPES since it looks like the
latest gcc release (2.7.2) fixes this in their own header files.
Sat Sep 21 10:45:43 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/OS.h: Added a new #define called ACE_HAS_BROKEN_MSG_H to the
config-osf1-3.2.h file and used it in OS.h to work around
problems with <msg.h> prototypes on that platform.
Fri Sep 20 00:15:29 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* Released version 4.0.31 for testing.
* ace/Pipe.cpp: Initialize handles_ to ACE_INVALID_HANDLE in
default constructor. Thanks to Tim Harrison for pointing this
out.
* ace: Copied in new versions of ace.{mak,mdp} for Win32.
* ace: Added TTY_IO.cpp to the Makefile.
* ace/config-win32-msvc[24].0.h: Updated the config file so that
it *doesn't* #define ACE_HAS_STRBUF_T since this type clearly
isn't available on Win32!
* ace: Modified all of OS.i and config-*.h files so that they
would be consisten with respect to handling the size_t and int
differences in socket implementations. Thanks to Chuck Gehr
<gehr@sweng.stortek.com> for helping with this for AIX.
* ace/ACE.h (ACE): Added a new method called max_handles() that
returns the maximum number of open handles currently supported
by the process.
* examples/Reactor/Misc/signal_tester.cpp: Revised the test to
utilize the new idioms for programming with signals.
* ace/OS.h: added a new #define called ACE_DEV_NULL that defaults
to "/dev/null" on UNIX and "nul" on NT. Thanks to David Trumble
<trumble@steosf.nio.dec.com> for reporting this fix.
* ace/Log_Msg.cpp: Added some checks to make sure that we don't
try to strdup() if we are passed a NULL pointer. Thanks to Luca
for suggesting this.
* ace/OS: Move ACE_Str_Buf into OS.{h,i} and remove the Str_Buf.h
file.
* Makefile: Added the "performance-tests" directory to the list of
directories we build when making ACE.
* ace: Moved the definition of strbuf from Str_Buf.h into OS.h.
Thanks to Irfan for recommending this.
* ace/Makefile: Added some additional sed magic on the
Svc_Conf_y.cpp file in order to remove the very last warnings
from MSVC++!
Thu Sep 19 00:00:17 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Service_Config.cpp (open): Only initialize the logger to use
STDERR if the user hasn't already set the ACE_Log_Msg::flags().
Thanks to Tom Leith <trl@icon-stl.net> for suggesting this.
* ace/OS: Removed all traces of the ACE_HAS_INT_SOCKNAME and
ACE_HAS_LENPTR_SOCKOPT since Chris Lahey's new fixes for AIX
obviate the need for these.
* ace/OS.i: Only #include <rpc/rpc.h> if the platform has RPC!
Thanks to Chuck Gehr <gehr@sweng.stortek.com> for suggesting
this.
* ace: Removed all uses of ACE_HAS_SETOWN and replaced them with
explicit tests for F_SETOWN and FASYNC. This is more portable.
Thanks to Chuck Gehr <gehr@sweng.stortek.com> for suggesting
this.
* ace/OS: Added a new #define called ACE_HAS_SIZET_SOCKET_LEN to
handle platforms where the length parameter of bind(),
connect(), accept(), etc. uses size_t rather than int. This
helps to get ACE working on MVS. Thanks to Chuck Gehr
<gehr@sweng.stortek.com> for suggesting this.
* ace/OS: Added Chris Lahey's fixes that make the
getprotoby{name,number}_r() functions work for AIX.
* ace: Changed the ACE_HAS_STRUCT_HOSTENT_DATA to
ACE_HAS_STRUCT_NETDB_DATA because we use a single symbol to
refer to all of the odd netdb.h stuff that AIX has...
* ace: Changed all uses of:
iovec *iovp = (iovec *) alloca (total_tuples * sizeof *iovp);
to
iovec *iovp = (iovec *) alloca (total_tuples * sizeof (iovec));
to keep the AIX compiler from complaining (falsely) about using
iovp before it is initialized. Thanks to Chris Lahey for
reporting this.
* ace/OS.h: Added Chris Lahey's changes that handle AIX's
_XOPEN_EXTENDED_SOURCE features without polluting all the socket
implementations!
* ace/Thread.cpp (spawn_n): Removed an unreferenced local variable
so that the Win32 compiler doesn't complain.
* ace/OS.h: Added the definition for strbuf{} for NT.
* ace: Removed the msg_hack.h file since it had OSF and DEC
copyright info in it. Replaced this with Antonio Tortorici's
<antonio@rh0011.roma.tlsoft.it> clever use of _KERNEL and the
new ACE_LACKS_SYSV_MSQ_PROTOS.
* ace/INET_Addr.h: Updated the documentation to indicate more
clearly the use of getservbyname().
* ace/OS.cpp (thr_create): Added basic hooks to support the use of
AfxBeginThread on Win32. This is necessary to allow ACE to work
seemlessly with MFC applications. Added an THR_USE_AFX flag
that can be "or'd" in with the other thread flags in calls to
ACE_OS::thr_create(). If this flag is enabled *and* if we are
compiling with ACE_HAS_MFC enabled, then AfxBeginThread() is
called rather than _beginthreadex().
* ace/INET_Addr.h (set): Fixed a typo in the documentation for
set() (the order of "host:port" was backwards...). Thanks to
Brad Flood <BFLOOD@tcs.lmco.com> for reporting this.
Wed Sep 18 00:36:01 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/SOCK_IO.cpp: Added a new recv() method that allows a client
to read from a socket without having to provide a buffer to
read. This method determines how much data is in the socket,
allocates a buffer of this size, reads in the data, and returns
the number of bytes read. The caller is responsible for
deleting the memory. Thanks to Luca Priorelli
<lucapri@mbox.vol.it> for suggesting this.
* ace/OS.h: Added a special #ifdef for IRIX 6.2 threads so that
THR_BOUND and THR_SCOPE_SYSTEM are different. Thanks to Gonzalo
Diethelm <gonzo@ing.puc.cl> for reporting this.
* ace/Message_Block.i (msg_class): Added a new "class" of messages
to ACE_Message_Block: MB_USER. This is useful for writing
extensible applications a la Microslush Windows MSG stuff...
Tue Sep 17 16:38:44 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Message_Block: Changed the signature of the
ACE_Message_Block constructors (and init()) so that they take
const char * rather than char *. In addition, changed the
definition of one of the constructors (and init()) so that it
takes a size field in addition to the buffer.
* ace/Message_Block.cpp (size): Fixed a bug in the
ACE_Message_Block::size() method -- we were failing to deal with
allocators and ownership correctly during a resize. Thanks to
Amos Shapira <amos_shapira@mail.icomverse.com> for reporting
this.
* ace/Naming_Context.cpp: Removed the source of yet another
warning about "inconsistent dll linkage. dllexport assumed."
* ace/Mem_Map.cpp (map_it): Added a cast to size_t (file_len)
because by this time we know that file_len >= 0. This avoids
yet another warning on WinNT!
* ace/Reactor.h: Fixed the remaining warnings about
"signed/unsigned mismatch" in Win32 by changing the type of
cur_size_ from size_t to ssize_t.
* ace/Log_Msg.cpp: Modified the code so that on NT we use
ACE_SPIPE_Msg rather than ACE_FIFO_Send_Msg. Thanks to Luca
Priorelli <lucapri@mbox.vol.it> for suggesting this.
* ace/OS.i: Implemented the and put[p]msg() wrappers by being
smart about allocating and copying data.
* ace/TTY_IO.cpp (control): There was one too many end parentheses
on line 192 of TTY_IO.cpp. Thanks to Dave Trumble
<trumble@steosf.nio.dec.com> for reporting this fix.
* ace/Log_Msg.cpp (local_host): Fixed the use of program_name_ and
local_host_ so that they strdup() the values passed by the
users, rather than copying pointers. This avoids problems if
the user doesn't pass in static memory. Thanks to Luca
Priorelli <lucapri@mbox.vol.it> for reporting this. Somehow
this change got lost and I've reapplied it...
* ace/Log_Record.cpp (round_up): Added an extra + 1 to the length
since otherwise the final '\0' gets lots if len is a multiple of
8. Thanks to Luca Priorelli <lucapri@mbox.vol.it> for reporting
this. Somehow this change got lost and I've reapplied it.
* ace/Memory_Pool.h: removed #if defined (ACE_HAS_SIGINFO_T) logic
from both handle_signal() definitions (ACE_Shared_Memory_Pool
and ACE_MMAP_Memory_Pool). Thanks to Chris Lahey for fixing
this.
* ace/OS.h: Moved the define of SA_RESTART below the #include for
signal.h. Otherwise SA_RESTART will always be defined by OS.h,
since SA_RESTART is defined on AIX in signal.h. Thanks to Chris
Lahey for fixing this.
* ace/OS.h: Added some new #pragmas to suppress harmless warnings
for the MSVC++ compiler.
Tue Sep 17 13:20:53 1996 Prashant Jain <pjain@merengue.cs.wustl.edu>
* ace/Local_Name_Space_T.cpp: Modified ACE_Local_Name_Space::
create_manager () so that all three naming scopes use the
database variable defined in Name Options. This allows us to
specify different names for databases for all three naming
contexts. However, it is imporant to note that this can lead to
potential problems where, for example, a process may use the
same name for PROC_LOCAL database as an already existing
NET_LOCAL database.
Mon Sep 16 01:31:21 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* examples/Logger/simple-server/Logging_Handler: get_handle(),
handle_input(), and handle_close() want the right types
(ACE_HANDLE instead of int). Thanks to Luca Priorelli
<lucapri@mbox.vol.it> for reporting these.
* examples/Logger/simple-server/Logging_Acceptor.cpp: Fixed a typo
(Log_Mskg.h should be Log_Msg.h of course...). In addition,
changed the use of -1 to ACE_INVALID_HANDLE. Thanks to Luca
Priorelli <lucapri@mbox.vol.it> for reporting these.
* ace: Changed all uses of ACE_HAS_ACE_INLINED_OSCALLS to
ACE_HAS_INLINED_OSCALLS. This was a vestiage of a global
replace gone amok. Thanks to Alan Stweart <Axs2@osi.com> for
reporting this!
* ace/Log_Msg.cpp (open): Added a check for the OSTREAM flag in
the ACE logger. Thanks to Rick Orr
<rorr@costello.den.csci.csc.com> for noticing this.
* Released version 4.0.30 for testing.
* netsvcs/clients/Naming/Dump_Restore/Dump_Restore.cpp
(Dump_Restore): Deleted an extra "return 0;" within a
constructor (duh...).
* examples/Threads/test_process_{semaphore,mutex}.cpp (main):
Fixed some annoying G++ compiler bug related problems. We need
to use old-style C casts to prevent ambiguous parsing.
* examples/ASX/Event_Server/Transceiver/transceiver: Rewrote this
example to illustrate how to use the ACE_Connector and
ACE_Svc_Handler.
* examples/ASX/Event_Server/Transceiver/transceiver: Finally clued
in and realized that it is just not suitable to implement the
event server transceiver with separate threads for input and
output. It is simply to non-portable to get these shut down
gracefully. I think John Ousterhout was right -- threads are
evil!
* examples/ASX/Event_Server: Merged the Consumer/Supplier
directories into a single Transceiver directory to reflect the
fact that the Consumer and Supplier were completely symmetrical!
* ace/Module.cpp (close): Don't delete the Tasks in a Module if
there are still threads running in them. Otherwise we'll end up
with a big mess.
Mon Sep 16 15:50:45 1996 Prashant Jain <pjain@merengue.cs.wustl.edu>
* performance-tests/Misc/test_naming.cpp: Added a new test to the
performance-tests directory called test_naming which simply does
performance testing on Naming Service. The test runs both the
SYNC and the NO-SYNC version of Naming Service.
Mon Sep 16 15:22:52 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu>
* ace/Proactor.cpp (initiate): Added a check for
ERROR_NETNAME_DELETED after ReadFile/WriteFile. Now the
initiating handler is immediately dispatched for EOF *and*
closed connections. Thanks to Luca Priorelli
<lucapri@mbox.vol.it> for suggesting this change.
Sun Sep 15 00:55:59 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* Fixed all uses of ACE_Service_Config::end_event_loop() and
ACE_Service_Config::run_event_loop() to be
ACE_Service_Config::end_reactor_event_loop() and
ACE_Service_Config::run_reactor_event_loop() since we now have
to consider the other event loops (e.g., Proactor and ReactorEx)
and it doesn't seem right to relegate those to 2nd class status.
* ace: Finally got fed up with all the #ifdefs required to deal
with extended signals and just changed the
ACE_Event_Handler::handle_signal() method to always use the
extended signal interface. Fortunately, we can use default
values to hid this from callers (though you may need to change
your class definitions if you were assuming the
handle_signal(int) interface.
* ace/Memory_Pool.h: Changed all the methods of the various
Memory_Pool classes to be virtual so that subclasses can
selectively override them. This shouldn't affect performance
since all existing use cases work directly with the "derived"
classes themselves, so there shouldn't be any overhead since the
compiler can use direct calls rather than virtual function
calls.
* ace/OS.cpp (thr_create): Changed the call to CreateThread() to
_beginthreadex() and the call to ExitThread() to _endthreadex()
for Win32 in order to make ACE threads work correctly with
Win32. Thanks to James Mansion <james@wgold.demon.co.uk> for
recommending this.
* ace/ACE: Added two new static functions: read_adapter() and
register_stdin_handler(). These are useful when writing code
that must demultiplexing ACE_STDIN on both Win32 and UNIX. This
works around Win32 limitations that don't allow us to select()
on non-sockets (such as ACE_STDIN).
* examples/ASX/CCM_App/SC_Server.cpp: Updated this
test so that it should now work correctly on Win32, where it
isn't possible to select() on STDIN...
* ace/Synch_T: Added a new class to ACE called "ACE_Test_and_Set."
As this name implies, this class implements an atomic ``test and
set'' abstraction. This has all sorts of useful implications,
particularly because it is a template that can be paramaterized
by the type of LOCK (e.g., ACE_Null_Mutex, ACE_Thread_Mutex,
etc.) and the type of TYPE (e.g., int, double, sig_atomic_t,
etc.). In addition, because this "is-a" ACE_Event_Handler it
instances can be registered with the Reactor and used to shut
down event hoops gracefully upon receipt of certain signals
(e.g., SIGINT). In fact, I've redone many of the example
applications (e.g., ./examples/Logger/server/server_loggerd.cpp)
to illustrate how this works.
Sun Sep 15 20:40:17 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu>
* ace/ReactorEx.cpp (notify): I've redesigned this code.
Previously, ReactorEx was explicitly managing a handle that it
kept in handles_[0]. handles_[0] was used to implement
ReactorEx::notify, which allowed other threads to wake up the
thread waiting in ReactorEx::handle_events. Now ReactorEx has
an Event_Handler (ReactorEx_Notify) that is registered in the
constructor of ReactorEx. This allows us to treat events from
handles_[0] just like every other event (i.e. by dispatching to
handles_[0]->handle_signal). One of the results of this change
is that code in remove_handler() is simplified a bit.
Sun Sep 15 17:56:52 1996 Prashant Jain <pjain@merengue.cs.wustl.edu>
* ace/Naming_Context.cpp: Added a new flag to the constructor and
open() method of ACE_Naming_Context that allows us to specify
which Memory_Pool to use when creating ACE_Local_Name_Space
(that is choose between ACE_MMap_Memory_Pool and
ACE_Lite_MMap_Memory_Pool).
* ace/Memory_Pool.cpp: Added a new class called
ACE_Lite_MMap_Memory_Pool which subclasses ACE_MMap_Memory_Pool
and overrides the sync method so that it is a no-op.
* ace/Local_Name_Space.cpp: Made some siginificant changes in
ACE_Local_Name_Space. Here is what the problem was:
ACE_Name_Space_Map (which is an ACE_Map_Manager) used an
ACE_RW_Process_Mutex for synchronization. However, since the Map
was kept in shared memory and was shared by all the processes,
it got instantiated only by the first process which came
along. Therefore, only the first process got around to creating
and initializing the lock.
In fixing the problem, we made some other changes to
ACE_Local_Name_Space and ACE_Name_Space_Map. Both classes are
now template classes. ACE_Local_Name_Space needs to be
parameterized with a Memory_Pool (thus giving us a hook to
implement the NO-SYNC option) as well as a LOCK.
ACE_Name_Space_Map needs to be parameterized by an ALLOCATOR
which is created by ACE_Local_Name_Space. Note that the reason
we need to parameterize ACE_Name_Space_Map is so that we can
pass an ACE_Allocator_Adapter (which subclasses from
ACE_Allocator) with every method. It is not possible to pass an
ACE_Allocator since the ::remap() method relies on an
allocator() method defined on the ALLOCATOR that is passed in
(and ACE_Allocator does not define an allocator() method).
The purpose of the class ACE_Name_Space_Map still remains the
same. It IS_A Map_Manager and provides the hook to set the
allocator to the process specific one. However, none of its
methods acquire any locks. For that reason, the Map_Manager is
parameterized with the Null_Mutex. All synchronization takes
place inside ACE_Local_Name_Space. ACE_Naming_Context
instantiates ACE_Local_Name_Space (depending upon the scope) and
by default parameterizes it with ACE_MMap_Memory_Pool and
ACE_RW_Process_Mutex.
Also made some more fixes to ACE_Local_Name_Space. In
create_manager(), after we create the allocator, we now check to
see if the backing store was created successfully and if not, we
return -1.
Sat Sep 14 00:00:31 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* examples/Logger: Renamed the original server directory to
"simple-server" and added a new directory called
"Acceptor-server" which implements the Logger using the
ACE_Acceptor. Note that almost all of the implementation code
disappears!
* ace/Local_Name_Server_T.cpp: Removed the name_server_map_ array
and replaced it with the ACE_NAME_SERVER_MAP #define, which is
now contained in OS.h.
* ace/Malloc.h: Added "virtual ... = 0" to the bind() and
trybind() methods of the ACE_Allocator since they should be pure
virtual functions...
* ace/Synch{_T}: Separated out the wait (ACE_Time_Value *) and
wait (void) methods in order to optimize the call sequence for
the common case when there is no timeout.
* ace/Synch: Added a new wait(ACE_Thread_Mutex &) method to
ACE_Condition_Thread_Mutex so that we are consistent with the
templated ACE_Condition_Mutex.
* include/makeinclude: Changed uses of -pic to -PIC because ACE is
now creating more than 2082 symbols. It's probably time to
split up the library...
* ace/DEV_IO: Moved the ACE_DEV_Addr instance from ACE_DEV_IO into
ACE_DEV so that it will be available for the ACE_DEV_Connector.
This fixes a bug that prevented us from using the ACE_Connector
in conjunction with the ACE_DEV_* classes. Thanks to Karlheinz
for clarifying what had to occur.
Fri Sep 13 00:16:32 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/OS.h: Changed the order of #includes so that <assert.h>
comes before <sys/stat.h>. This fixes some bugs with the
Siemens SVR4 C++. Thanks to Antonio Tortorici
<antonio@rh0011.roma.tlsoft.it> for this fix
* ace/ACE.cpp (handle_timed_complete): Added yet another weird
hack to deal with the insanity that is TLI...
* ace/Synch.cpp: Replaced all uses of ACE_Thread_Mutex_Guard with
ACE_GUARD macros in order to avoid problems when mutexes fail.
* ace/OS.h: Changed the definition of the ACE_*GUARD macros so
that they are always enabled, even when we turn off ACE_MT_SAFE.
This avoids a nasty semantic problem for components that use
ACE_Process_Mutex. Thanks to Avraham Nash
<Avraham_Nash@praxisint.com> for reporting this problem.
* ace/OS: Removed ACE_OS::fork_exec() since its functionality has
been subsumed by ACE_Process.
* ace/Thread_Manager: Added a new thread_descriptor_i() method
that *doesn't* grab the lock in order to avoid deadlocks.
* include/makeinclude/platform_sunos5_sunc++.GNU (CXX): had to add
the -pta option so that we achieve template closure in ACE.
* include/makeinclude: Added -lthread to the
platform_sunos5_sunc++.GNU file. I don't know how this slipped
through the cracks!
* ace/{DEV_IO,FILE_IO,SOCK_IO,SPIPE_Stream}: Fixed a braino with
alloca where I was failing to multiply by sizeof (iovec). Isn't
C great? ... Thanks to Chuck Gehr <gehr@sweng.stortek.com> for
reporting this.
* ace/SOCK_Dgram_Mcast.cpp: Added two changes to the ACE multicast
code in order to get it to work on Win32. The first change is
to put the IP_ADD_MEMBERSHIP setsockopt() call *after* the
bind() (in shared_open()). The second is to convert the
ACE_INET_Addr::get_ip_address() from host byte order into
network byte order. Thanks to Todd L. Montgomery
<tmont@cerc.wvu.edu> and Steve Weismuller
<spweismu@rsoc.rockwell.com> for helping with this.
* examples/Threads/test_barrier2.cpp: Incorporated Karlheinz's
new ACE_Barrier test program.
* ace/Synch.h: Added Karlheinz's ACE_Null_Barrier class.
Fri Sep 13 00:30:50 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu>
* tests/{Tokens_Test,Time_Service_Test}.cpp: Updated tests to use
ACE_Process instead of ACE_OS::fork_exec.
* ace/Process.cpp: Added a new ACE_Process abstraction that is a
Portable encapsulation for creating new processes. It allows
assignment of STDIN, STDOUT, and STDERR of the new process. On
UNIX, ACE_Process uses fork and exec. On Win32, it uses
CreateProcess. Since we can set the standard handles, we can
mimic UNIX pipes on Win32 by building chains of processes. This
class should be used instead ACE_OS::fork_exec.
* examples/OS/Process/process.cpp (main): Added new example
application to show how to use ACE_Process.
Thu Sep 12 00:55:25 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/DEV_IO: Added methods get_local_addr() and get_remote_addr()
so that ACE_Connector will work correctly. Thanks to Brad Flood
<BFLOOD@tcs.lmco.com> for reporting this.
* ace/Thread_Manager.cpp (thr_self): Added a fix to solve the
problem that Win32 GetCurrentThread() returns a pseudo-handle
rather than a real handle. Now, we just look things up using
the thread id rather than the thread handle. Thanks to Luca
Priorelli" <lucapri@mbox.vol.it> for clarifying this.
* ace/Proactor.cpp (initiate): Fixed an incorrect set of return
values -- they were reversed. Thanks to Brad Flood
<BFLOOD@tcs.lmco.com> for reporting this.
* ace/OS.i (thr_cmp): Added a check for
!defined(ACE_HAS_SETKIND_NP) to avoid a problem with OSF/1.
Thanks to Martin Schoeckle <schoeckle@ike.uni-stuttgart.de> for
reporting this.
* examples/IPC_SAP/DEV_SAP: Updated these examples to use the new
ACE_TTY_IO classes.
* ace: Moved the TTY_IO code from the
examples/IPC_SAP/DEV_SAP/{reader,writer} directories into the
files TTY_IO.{h,cpp} in the main part of ACE and integrated Brad
Flood's <BFLOOD@tcs.lmco.com> changes for Win32.
* ace/DEV_IO.i: Changed the mapping of send_n() and recv_n()
methods to use write_n() and read_n() respectively so they will
work on NT. Thanks to Brad Flood <BFLOOD@tcs.lmco.com> for
reporting this.
* ace/Thread_Manager.h: Implemented a non-synchronized version of
the lookup function for the <hthread_descriptor>. This version
assumes that the lock is help. We need this to avoid
intra-class method deadlock on systems (such as Solaris) that
lack recursive mutexes.
* ace/Log_Msg.cpp (ACE_Log_Msg): made sure to initialize
ACE_Log_Msg::thr_handle_ to 0. I'm not sure how this got
changed... Thanks to Luca Priorelli <lucapri@mbox.vol.it> for
reporting this.
* examples/Reactor/ReactorEx/test_reactorEx.cpp
(register_thread_exit_hook): Changed hthread_t to ACE_hthread_t.
Thanks to Luca Priorelli <lucapri@mbox.vol.it> for reporting
this.
* apps/Gateway/Gateway/Channel.h: Due to inconsistencies between
the semantics of sockets and TLI with respect to establishing
non-blocking connections it's not a good idea to use TLI in
conjunction with select(). Therefore, I've #if 0'd out the use
of TLI in the Gateway application.
Wed Sep 11 00:25:38 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/ACE.cpp (handle_timed_complete): Fixed a typo that was
failing to set n = ACE::recv(...). In addition, rethought how
we figure out if a connection completes for the nth time...
* ace/TLI.cpp (open): Modified the implementation of open() so
that if oflag == 0 it is given an initial value of O_RDWR.
Otherwise we'll get a "badflags" t_errno.
* ace/Connector.h (connect): Modified connect() so that the
default value of the flags parameter is O_RDWR. This is
necessary to make TLI_Connector::connect() work correctly by
default.
* examples/Logger: Updated the example logger client and server to
illustrate more clearly how things like the Singleton Reactor
and the ACE_Reactor timer mechanism work. Thanks to Joe
DeAngelis <bytor@faxint.com> for suggesting this.
* ace/Pipe: Added a new constructor that makes it possible to
initialize the <ACE_Pipe> from the <read> and <write> handles.
Thanks to Stevan Warwick (sjw@aesthetic.com) for suggesting
this.
* config-irix5.3-sgic++.h: Added #define for ACE_NEEDS_SYSTIME_H.
Thanks to Stevan Warwick (sjw@aesthetic.com) for reporting this.
* examples/Logger/server/Client_Acceptor: Fixed some stray
mis-uses of int that should have been ACE_HANDLE. Thanks to
Luca Priorelli" <lucapri@mbox.vol.it> for reporting this.
* ace/{ACE,Log_Msg}.cpp: Added fixes for hexdump(). Thanks to
Luca Priorelli" <lucapri@mbox.vol.it> for supplying these.
* ace/Reactor.cpp (ACE_Reactor): Fixed a typo: "this->max_handlep1
()" should be "this->handler_rep_.max_handlep1 ()". Thanks to
Scott Shupe <shupes@mitre.org> for reporting this.
* apps/Orbix-Examples/Event_Comm: Added a bunch of changes to make
this application compile with Orbix 2.0. Thanks to Mike
O'Malley <momalley@caesun16.msd.ray.com> for the fixes.
* ace/OS.cpp (thr_create): Added yet another fix for the IRIX 6.2
pthreads implementation. Thanks to Gonzalo Diethelm
<gonzo@ing.puc.cl> for reporting this.
* ace/config-irix6.2-sgic++.h: Changed ACE_HAS_IRIX53_GETTIMEOFDAY
to ACE_HAS_IRIX_GETTIMEOFDAY because this also seems to be the
case for IRIX 6.2... Thanks to Gonzalo Diethelm
<gonzo@ing.puc.cl> for reporting this.
* ace/TLI_{Connector,Acceptor}.cpp: Added tests against NULL
pointers to avoid segmentation faults when the TLI
implementation doesn't allocate memory for the udata and opt
fields of netbuf structures.
* ace/Mem_Map.i (ACE_Mem_Map): Added an accessor so that callers
can get the name of the filename that is being used as the
backing store. Thanks to the James Mansion
<james@wgold.demon.co.uk> for recommending this.
Tue Sep 10 00:26:52 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/OS.cpp (thr_create): Modified the thr_create()
implementation for Win32 so that if the caller doesn't care
about this value we can avoid a HANDLE leak. Thanks to the
James Mansion <james@wgold.demon.co.uk> for recommending this.
* ace/Thread.cpp (ACE_Thread): Moved both definitions of spawn_n()
into the Thread.cpp since they have loops and don't benefit from
being inlined.
* ace/Svc_Handler.h: Moved operator delete() into the public part
of the class in order to make various compilers happy...
* ace/OS.i (ACE_OS): Fixed the #define that selects the (union
wait *) alternative of wait(). This original was protected by
ACE_LACKS_POSIX_PROTO, but it should be ACE_HAS_UNION_WAIT.
* performance-tests: Created a new directory that will contain all
of the ACE performance tests. Move the Synch-Benchmarks and the
TTCP tests from ./apps into here, and also moved the
test_mutex.cpp and test_singleton.cpp files from
./examples/{Threads,Misc}, respectively. Thanks to Tim Harrison
for this suggestion.
* ace/OS.i (ACE_OS): in WIN32 closesocket() returns 0 if call is
OK, so I changed the return value to be the other way around.
Thanks to Luca Priorelli <lucapri@mbox.vol.it> for reporting
this.
* ace: Changed the ACE_NO_POSIX_PROTO #define to something more
meaningful: ACE_LACKS_POSIX_PROTO. Thanks to Jonathan Biggar
<jon@sems.com> for suggesting this.
* ace/config-sunos4-g++.h: Added the #define ACE_NEEDS_SYSTIME_H.
Thanks to Alexandre Karev <akg@na47sun05.cern.ch> for reporting
this.
* ace/OS: Fixed a bunch of pthreads portability problems that
showed up on OSF/1 4.0. Also added support for asctime_r() and
ctime_r() for OSF/1 4.0. Thanks to Dave Trumble
<trumble@steosf.nio.dec.com> for reporting these fixes.
* ace/Synch_T.cpp (ACE_TSS_Read_Guard): Removed a stray "new" that
was causing problems for the ACE_NEW macro. Thanks to Dave
Trumble <trumble@steosf.nio.dec.com> for reporting this.
* ace/Local_Tokens.h: Fixed a broken use of "friend", which was
missing the keyword "class." Thanks to Dave Trumble
<trumble@steosf.nio.dec.com> for reporting this.
* ace/config-osf1-4.0.h: Included Dave Trumble's
<trumble@steosf.nio.dec.com> config file for OSF/1 4.0.
* include/makeinclude/platform_osf1_4.0.GNU: Included Dave
Trumble's <trumble@steosf.nio.dec.com> platform macros file for
OSF/1 4.0. Also renamed platform_osf1.GNU to
platform_osf1_3.2.GNU to deal with the new version.
* ace/Proactor: There wasn't a way to destroy an
ACE_Overlapped_File object without closing the ACE_HANDLE
attached to it. Therefore, I added a flag that keeps track of
whether we have to delete this or not. Thanks to Amos Shapira
<amos_shapira@mail.icomverse.com> for suggesting this.
* examples/Threads/test_future[12].cpp: Updated the tests to use
the new call() semantics in order to shut down the Scheduler's
event loop gracefully.
* ace/Method_Object.cpp: Added a return value to the call()
routine. This can be used to indicate to the caller that it is
necessary to shut down the event loop.
Mon Sep 9 02:07:08 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Service_Config.cpp (ACE_Service_Config): #ifdef's out the
registration of signal handling to control reconfiguration on
Win32 since it doesn't really handle signals very well. Thanks
to John Morey <jmorey@tbi.com> for bringing this to my
attention.
* ace/CORBA_Handler: Replaced CORBA_[123] with ACE_CORBA_[123].
* examples/CORBA: Updated the test programs to work portably
across different versions of Orbix.
* ace/OS: Added a new wrapper for the getcwd() call.
* examples/Threads/test_recursive_mutex.cpp: Added the use of
ACE_Guard<> to illustrate how these work with the
ACE_Recursive_Thread_Mutex. Thanks to Gonzalo Diethelm
<gonzo@ing.puc.cl> for motivating me to do this.
* examples/Threads/test_process_{mutex,semaphore}: Added two new
tests to illustrate how the ACE_Process_Mutex and
ACE_Process_Semaphore work, respectively.
* ace/Synch: Replaced the implementation of ACE_Process_Semaphore
to use SV_Semaphore_Complex on UNIX platforms in order to get
the same semantics for Win32 and for UNIX. Thanks to the James
Mansion <james@wgold.demon.co.uk> for recommending this.
* ace/OS.h: Added some parens around the ACE BIT* macros so that
the precedence levels would be dealt with correctly and we don't
get any nasty surprises...
* ace/{Synch_T,Synch}: Modified the implementation of all the
*acquire()/release() methods so they keep track of whether they
own the mutex. Thus, if a code path needs to give up the mutex
within the lifetime of the mutex, and it calls mutex_.release(),
then the destructor will not call it again. Thanks to the James
Mansion <james@wgold.demon.co.uk> for recommending this.
* ace/{Synch_T,Synch}: Changed the name of the field result_ to
owner_ for the ACE_Thread_Muetx_Guard and ACE_Guard. This is
more representative of the true purpose of this field.
* ace/Synch: Updated ACE_Thread_Mutex_Guard so that it has the
same interface and semantics of ACE_Guard. Thanks to the
ever-vigilant James Mansion <james@wgold.demon.co.uk> for
noticing this.
* examples/Log_Msg/test_log_msg.cpp (main): Added a test of the
new ACE_Log_Msg::priority_mask() functionality.
* ace/Log_Msg.cpp: Added a new method called priority_mask(),
which updates the new thread-specific priority_mask_ data member
with the new mask and returns the old mask. This is useful for
applications written using ACE_Log_Msg. Often, these have log()
calls with low priority such as LM_DEBUG that don't need to be
printed, but for which the logging code should not be removed.
The priority_mask() scheme makes it possible to selective enable
printing of certain priorities. Thanks to Rochi Febo Dommarco
<rocky@alter.it> for suggesting this.
* netsvcs/clients/Logger/indirect_logging.cpp (main): Modified the
test program so that it randomly selects logging priorities that
are powers of two.
* ace/Log_Priority.h: Renumbered the LM_* logging flags so that
they are all powers of two. This makes it easy to implement a
scheme for selectively printing only certain logging values.
Sun Sep 8 10:46:40 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/Proactor.cpp: Fixed up the error handling in ACE_Proactor so
that it returns an error both in case of "bad errors," as well
as when ACE_WIN32 isn't defined. Thanks to Amos Shapira
<amos_shapira@mail.icomverse.com> for reporting this.
Sun Sep 8 14:11:08 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu>
* examples/Reactor/Proactor/README: Updated the test_proactor.cpp
and README files to clarify the relationship between the
Proactor and ReactorEx. This example uses the Proactor as the
main event loop (not the Reactor or ReactorEx). Thus, this
application can only do overlapped I/O and timers
asynchronously. To be able to react to other Win32 events, see
the ACE_ReactorEx and the examples/Reactor/ReactorEx/ test.
Thanks to Amos Shapira <amos_shapira@mail.icomverse.com> for
pointing out the ambiguity.
Sat Sep 7 14:09:21 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/Task.cpp: Enhanced the activate() method so that the caller
can set the priority and the thread group id. Thanks to
Karlheinz for this suggestion.
* ace/OS.h: Added default values of 0 for the trailing arguments
for the {mutex,sema,cond}_init() methods.
* examples/Threads/test_mutex.cpp: Added a new test program that
illustrates the difference between implementations of thread
mutex wrappers that use inheritance and dynamic binding vs. the
ACE approach (which doesn't use inheritance and dynamic
binding). The results I got on my SPARCstation 20 model 712 is
included in the source file. Thanks to James Mansion
<james@wgold.demon.co.uk> for motivating me to write this.
* examples/Misc/test_singleton.cpp: Added a new test program that
illustrates the performance of using the Double-Checked Locking
pattern compared with the standard "Mutex::acquire()/release()"
approach. Thanks to Jim Coplien <cope@research.bell-labs.com>
for encouraging me to get these performance numbers.
Tue Sep 3 00:38:47 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/XtReactor: Added minor fixes to XtReactor to fix complaints
about "bool" not being defined and the destructor
~ACE_XtReactor() has already having a body. Thanks to Andres
Kruse <Andres.Kruse@cern.ch> for these fixes.
* ace/Mem_Map.cpp: Make sure that this->length_ is initialized to
0 in ACE_Mem_Map::map (). Thanks to James Mansion
<james@wgold.demon.co.uk> for pointing this out.
* ace/Thread.i (spawn_n): In ACE_Thread::spawn_n the sense of the
following check is wrong:
for (i = 0; i < n; i++)
// Bail out if error occurs.
if (ACE_OS::thr_create (func, arg, flags, &t_id, 0, priority,
stack == 0 ? 0 : stack[i],
stack_size == 0 ? 0 : stack_size[i]) != 0)
thread_ids[i] = t_id;
else
break;
The '!=' should be '=='. Thanks to James Mansion
<james@wgold.demon.co.uk> for pointing this out.
* include/makeinclude/rules.local.GNU (MAKEFILE): Changed the
$WRAPPER_ROOT/include/makeinclude/rules.local.GNU line that
says:
sed -e "s:$(WRAPPER_ROOT);$$(WRAPPER_ROOT);g" \
so that the double dollar is now "\$$" (prefixed the first
dollar sign with a backslash). If not, my shell will try to
execute WRAPPER_ROOT for some reason. With "\$$" it works as it
should. Thanks to Marius Kjeldahl <marius@funcom.no> for
reporting this.
* Released version 4.0.29 for testing.
* ace/OS.i (thr_getspecific): Added a new case for OSF/1. Thanks
to Martin Schoeckle <schoeckle@ike.uni-stuttgart.de> for
reporting this.
* ace/Thread_Manager.cpp (spawn_i): Removed an invalid
initialization of ACE_hthread_t = 0, which doesn't work on all
pthreads platforms because pthreads uses a struct in some
implementations. Thanks to Martin Schoeckle
<schoeckle@ike.uni-stuttgart.de> for reporting this.
* man: Updated all the nroff and html documentation to conform to
the latest version of ACE.
* netsvcs/lib/{Name_Handler,TS_Server_Handler}.cpp: Fixed
some mistakes in the ACE_TEMPLATES_REQUIRE_SPECIALIZATION
code so that all the services can be linked together without
multiply defined symbols.
* netsvcs/lib/Name_Handler.cpp: Fixed a spot where we weren't
passing in an lvalue to send_request(). Why this wasn't showing
up earlier I don't know, but GCC caught it!
Mon Sep 2 00:47:00 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/Thread_Manager.cpp: Updated all comparisons of ACE_thread_t
and ACE_hthread_t so that they use the ACE_OS::thr_equal() and
ACE_OS::thr_cmp() methods, respectively. Thanks very much to
Martin Schoeckle <schoeckle@ike.uni-stuttgart.de> for identify
the need for this.
* ace/OS: Added a new method called thr_cmp() which compares two
ACE_hthread_t values for equality. Unfortunately, we can't just
compare these directly via == because on some platforms they are
implemented as structs. Right now, I'm assuming that if
ACE_HAS_TID_T is enabled that we can compare tid_t's using ==.
If this turns out to be incorrect (e.g., if tid_t's are also
implemented as structs, please let me know).
* ace/Future: Changed the overloaded result() method to a pair of
get()/set() methods.
* tests/test_config.h: Fixed a bug in the reset() routine. This
was originally deleting the global static ace_file_stream.
However, this was causing segmentation faults if destructors for
objects local to main() were trying to write to the output file.
Therefore, instead of deleting the ostream, we simply flush()
it!
In addition, also renamed the various functions in test_config.h
to make sure they don't conflict with any other names by
prefixing them with ace_test_...
* ace: Added many small fixes for IRIX 6.2. Thanks to Gonzalo
Diethelm <gonzo@ing.puc.cl> for reporting all of these!
* ace/OS: Added a wrapper for the UNIX syscon() system call.
* ace/LSOCK.cpp (recv_handle): Rearranged the casts so that things
work correctly on platforms with odd definitions ot struct
iovec. Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl> for
reporting this.
* ace/Task.cpp (ACE_Task_Exit): Rearranged the order in which we
shut down a Task via the Task_Exit hook so that we first
decrement the count of the threads in the task and *then* call
its close() hook. This guards against cases where the close()
hook does something crazy like "delete this".
* ace/XtReactor.h: Changed #include "X11/Intrinsic.h" to #include
<X11/Intrinsic.h>. Thanks to Gonzalo Diethelm
<gonzo@ing.puc.cl> for suggesting this.
* ace/Future.cpp (ACE_Future): Added some strategic "consts" to
the assignment operator and copy constructor for ACE_Future and
ACE_Future_Rep.
* examples/Threads/test_task_three.cpp (main): Revised the test so
that it will shut itself down automatically when all the threads
have finished.
* examples/Threads/test_task_two.cpp (main): Revised this test so
that it doesn't run forever, but only runs either 1000 times or
as many times as the user specifies on the command line. Thanks
to Gonzalo Diethelm <gonzo@ing.puc.cl> for suggesting this.
* ace/OS.i: Added an extra #else for thr_sigsetmask(),
thr_min_stack(), and thr_kill() for weirdo platforms that don't
conform to the other threading APIs...
Sun Sep 1 20:15:28 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* examples/ASX/Message_Queue: Changed the use of read(0, ...) and
write(1, ...) to ACE_OS::read(ACE_STDIN, ...) and
ACE_OS::write(ACE_STDOUT, ...) in buffer_stream.cpp and
bounded_buffer.cpp.
* ace/OS.i: Fixed the errno mapping of the cond_timedwait()
functions so that they set errno to ETIME rather than EBUSY when
timeouts occur. This is necessary to support Solaris and POSIX
pthreads semantics on Win32.
* build/SunOS5.5/examples/ASX/Message_Queue/buffer_stream.cpp:
Modified the example somewhat so that it uses the Singleton
thr_mgr() method from ACE_Service_Config.
Sun Sep 1 17:29:58 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu)
* ace/ACE.cpp (map_errno): Added a new static method to the ACE
class. This method allows us to map troublesome win32 errno
values (e.g. WSAEWOULDBLOCK) to values that standard C strerr
function understands. Thank you Microsoft.
* ace/Log_Msg.cpp (log): Added a call to ACE::map_errno to the %p
option. Now the ACE logger can begin to map Win32 error values
into meaningful strings.
* netsvcs/lib/lib.mdp: Added a project file for the netsvcs
library. This builds a dll into ace/netsvcs.dll (not into the
netsvcs/lib directory). This reduces the number of paths needed
in %PATH%.
* examples/Tokens: Renamed this directory netsvsc/clients/Tokens.
* ace/ace.mdp: Removed wsock32.lib from the ace files listing.
The problem is that we can't assume where MSDEV is installed. I
added wsock32.lib and advapi32.lib to the
build/settings/link/library_modules line.
* ace/config-win32-msvc4.0.h: Disabled the "C4355: 'this' : used
in base member initializer list" warning. Thanks to Amos
Shapira for figuring this out for us. Although "this" is
unneeded for win32, it is required for compilers on other
platforms (e.g., AIX).
* ace/Message_Queue.cpp (dequeue_head_i): Andres Kruse pointed out
that we weren't doing head_->prev (0), when dequeuing!
Tue Aug 27 21:00:25 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* include/makeinclude/platform_sunos5_sunc++_4.1.GNU (CXX): Added
Andres Kruse's changes for SunC+ 4.1.
* ace: Fixed line # 12 of ace/config-sunos4-sun4.1.4.h,
which read:
"#define ACE_HAS_SVSV_IPC" (ACE_HAS_ ess vee ess vee _IPC)
to
"#define ACE_HAS_SYSV_IPC" (ACE_HAS_ ess wye ess vee _IPC)
Fix another problem:
#define ACE_LACKS_THREAD_STACK_ADDR (OS.cpp)
was inconsistently defined in:
#define ACE_LACKS_THREAD_STACK_ADDRESS (config-aix-4.1.x.h)
Thanks to Alan Stweart <Axs2@osi.com> for reporting
this!
Mon Aug 26 00:34:05 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* Updated all of ACE such that the ACE_GUARD* macros now all take
the name of the ACE_*Guard* that they will use as the scoped
locking object. This is important for several reasons:
1. It make it more clear what is going on in the code, rather
than hiding behind the macros!
2. It is now possible to have multiple ACE_GUARD* macros in the
same scope by calling each scoped locking object a different
name. This is used in the Local_Tokens.cpp file.
* ace/Synch.h (ACE_Null_Mutex_Guard): Added the locked() method so
that this signature will conform to the one expected of
ACE_Guard.
* tests: Added a new file Test_Future.cpp, which tests the new ACE
Futures mechanism using Active Obejcts. Thanks to Andres Kruse
<kruse@cern.ch> for contributing this test.
* ace: Added three new files: Future.{h,cpp},
Method_Object.{h,cpp}, and Activation_Queue.{h,cpp}, which
implement Polymorphic Futures. Thanks to Andres Kruse
<kruse@cern.ch> for contributing these.
* ace/Stream.cpp (dump): Replaced LM_INFO with LM_DEBUG.
Sun Aug 25 21:57:57 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace: Rather than using operator new directly, most of ACE now
uses the ACE_NEW and ACE_NEW_RETURN macros. For instance,
rather than writing:
if (token_manager_ == 0)
token_manager_ = new ACE_Token_Manager;
we should write:
if (token_manager_ == 0)
ACE_NEW_RETURN (token_manager_, ACE_Token_Manager, 0);
The reason for this is that it makes it much easier to ensure
that all dynamic memory allocation errors are treated uniformly.
I've updated the entire ACE library code tonight to make this
usage consistent whenever possible.
Sat Aug 24 11:51:38 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/Time_Value.h: Simplified various things so that the nasty
macros necessary to build DLLs on Win32 will be simplier. In
addition, I will only #include <sys/time.h> for those platforms
that don't already do this in <time.h> (i.e., if
ACE_NEEDS_SYSTIME_H is defined in config.h). Please let me know
if you run across any platforms like this.
* ace/TLI_{Connector,Acceptor}: Added two additional parameters at
the end of the connect() and accept() methods, respectively, so
that the ACE TLI wrappers can be used with X.25. Thanks to Ajit
Sagar <asagar@spdmail.spd.dsccc.com> for suggesting this fix.
* ace: Integrated Eric Newton's XtReactor into the Makefile. If
you want to include this into ACE, make sure to define
ACE_HAS_XT in the config.h file.
* examples/Misc: Integrated the XtReactor tests.
* ace/OS.i (getservbyname,gethostby*): Fixed a suble omission --
any calls to socket function should be wrapped by the
ACE_SOCKCALL_RETURN macro in order to make the errnos work
correctly on Win32.
* ace/OS: Added support for the getprotoby{name,number} wrappers.
Thanks to Joe DeAngelis <bytor@faxint.com> for suggesting this.
* ace/Connector.cpp: Fixed a subtle bug in the ACE_Connector.
The problem centered around the following line in
cleanup_AST():
if (this->handler_map_.find (handle, ast) == -1)
This lookup always failed because the key, the handle of the
service handler, was always -1. The service handler's handle is
not set until a successful connection is made and connector
transfers ownership of the handle to the service handler. The
fix for this is to store the ACE_HANDLE in the ACE_Svc_Tuple
*separately* from the ACE_Svc_Handler. Thanks to Bill Gerecke
<gerecke@rayva.org> for being so persistent in tracking this
down.
* ace/ARGV.cpp (ACE_ARGV): Added a nifty new constructor that
converts argv-style vectors of strings into a single string
(this is the reverse of what the original constructor does!).
* ace/ACE: Added a new utility method called strecpy(), which
copies <t> to <s>, returning a pointer to the end of the copied
region (rather than the beginning, a la <strcpy>.
Thu Aug 22 15:43:58 1996 <harrison@samba.cs.wustl.edu>
* ace/OS.h: Changed the interface of ACE_OS::fork_exec (char
*const argv[]). (There is no longer a separate const char *path
parameter. Now, argv[0] must be the full path name to the
executable.
* tests/Time_Service_Test.cpp: Updated the Time Service
one-button test to use the new ACE_OS::fork_exec. I didn't
event break it.
* tests/Tokens_Test.cpp: Updated the Tokens one-button test to
use the new ACE_OS::fork_exec. It actually works now.
* tests/test_config.h: Added some more #defines to help simplify
path differences between NT and UNIX. Perhaps these should be
moved into OS.h?
Thu Aug 22 13:46:58 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/Thread_Manager.cpp (ACE_Thread_Control): The status_ member
in ACE_Thread_Control() was not being initialized! This caused
Purify to complain loudly about invalid memory accesses. I have
added an initialiser to ACE_Thread_Control::ACE_Thread_Control
to set status_ to 0. Thanks to Ross Dargahi <rossd@krinfo.com>
for reporting this.
* ChangeLog: The ACE configuration files "config-irix*.h" defined
'ACE_HAS_SIGINFO' to indicate that IRIX supports SVR4 extended
signals. This should be 'ACE_HAS_SIGINFO_T' instead. Thanks to
Craig Johnston <johnston@tortilla.ds.boeing.com> for reporting
this.
Wed Aug 21 21:09:01 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* ace/Time_Value.h: Added an extra condition, #if defined
(ACE_BUILD_DLL) so that ACE_Svc_Export evaluates to
something. Previously, it was evaluating to nothing in some
files such as Naming_Context.cpp where we were doing #define
ACE_BUILD_DLL and not #define ACE_BUILD_SVC_DLL.
Wed Aug 21 00:33:17 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/ACE.cpp (format_hexdump): Fixed a minor bug in
format_hexdump(). If the buffer to dump is a multiple of 16 it
prints an extra blank line. ALso fixed the code to use spaces
rather than tabs and put an extra space between the first 8 HEX
bytes and the second. Thanks to Luca Priorelli
<lucapri@mbox.vol.it> for this code.
* ace/Log_Msg.h (ACE_HEX_DUMP): Added a new logging macro:
#define ACE_HEX_DUMP(X) \
do { int __ace_error = errno; \
ACE_Log_Msg *ace___ = ACE_Log_Msg::instance (); \
ace___->set (__FILE__, __LINE__, 0, errno, ace___->restart (),
ace___->msg_ostream ()); \ ace___->log_hexdump X; \
} while (0)
which makes it possible to dump info in HEX. Thanks to Luca
Priorelli <lucapri@mbox.vol.it> for suggesting this.
* ace/config-win32-msvc4.0.h: Added
#define _WINSOCKAPI_
To avoid multiple inclusions. Thanks to Luca Priorelli
<lucapri@mbox.vol.it> for suggesting this.
* ace/OS.h: enclosed the #define of WIN32_LEAN_AND_MEAN macro
definition between #ifndef ... #endif to avoid compiler
warnings. Thanks to Luca Priorelli <lucapri@mbox.vol.it> for
suggesting this.
* ace/SOCK.cpp (win32_fini): Fixed a potential problem in ACE
where any code of the form:
ACE_DEBUG ((LM_DEBUG, "%d", GetLastError()));
will reset errno a couple of times before GetLastError() gets
called. So the result is always 0. The fix is to say:
int ret = GetLastError();
ACE_DEBUG ((LM_DEBUG, "%d", ret));
Thanks to Luca Priorelli <lucapri@mbox.vol.it> for noticing
this.
* ace/Connector.cpp (create_AST): Was missing a return 0; if we
successfully register a cancellation id. Thanks to William
L. Gerecke <gerecke@rayva.org> for reporting this bug.
* ace/Module.h: Added a non-existent friend class to get ACE
to stop complaining
private:
friend class ACE_Shutup_GPlusPlus; // Turn off g++ warning
~ACE_Module (void);
// *Must* use dynamic allocation.
Thanks to Eric Newton for the suggestion.
* ace/Svc_Conf.y (ace_create_service_type): Removed some stray
calls to ACE_ERROR that were left over from earlier
configurations of ACE. Thanks to Gonzalo Diethelm
<gonzo@ing.puc.cl> for reporting this.
* ace/Log_Msg.cpp (instance): Fixed the #ifdefs so that
ACE_MT_SAFE implies ACE_HAS_THREAD_SPECIFIC_STORAGE. Thanks to
Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting the need for
this.
Tue Aug 20 13:09:55 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* INET_Addr.cpp, line 84: Irix's C++ is not able to determine
whether to use the set(u_short,ACE_UINT32,int) or the
set(u_short,const char [],int), since on Irix, INADDR_ANY is 0.
I cast the value so that the call would read set(port,
ACE_UINT32(INADDR_ANY)) and everything went fine. Thanks to
Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting this.
* ace/Synch[_T]: Added a new wait() method that takes a first
parameter which is the mutex used to serialize access to the
condition. This is useful if you want to store the
ACE_Condition object in shared memory (in which case, the use of
a reference to mutex_t doesn't work!). Thanks to Mark Patton
<mark_patton@ftw.paging.mot.com> for recommending this approach.
* ace/Task.h: Added a forward template declaration for
ACE_Task_Exit so that it will compile on HP/UX. Thanks to Tim
Ottinger <tottinge@csci.csc.com> for pointing this out.
* ace: changed line 19 of ace/Str_Buf.h from
#include "OS.h"
to:
#include "ace/OS.h"
Fixed similar problems with OS.h at line 1154 and Dump.h at line
150. Thanks to Alan Stewart <axs2@osi.com> for reporting this.
Tue Aug 20 20:18:49 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* tests/TSS_Test.cpp (main): Fixed a small typo. I was referencing
the wrong variable but didn't catch it since it was in the #if
!defined (ACE_HAS_THREADS) section. Fixed the typo and also
renamed the variable called big_count to iterations. Thanks to
Tim Ottinger <tottinge@csci.csc.com> for pointing this out.
Mon Aug 19 19:25:50 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* {examples,apps,tests}: Removed the use of zerop from these
files, as well...
* ace/{Acceptor.cpp,Name_Proxy.cpp,Token.i}: Removed the use of
zerop from these files, as well...
* ace/Connector.cpp (connect_svc_handler): It looks like our good
friend ACE_Time_Value::zerop isn't getting initialized correctly
on Win32. Therefore, I've replaced it with a direct use of
&ACE_Time_Value::zero.
* ace/Time_Value.cpp: Removed the static pointer variable "zerop"
since there was no guarantee it was getting intialized before it
is used! Instead of using ACE_Time_Value::zerop, use
&ACE_Time_Value::zero. Thanks to William L. Gerecke
<gerecke@rayva.org> for reporting this problem.
* ace/OS: Added zillions of changes to make ACE compile with OSF/1
and its DCE threads implementation. Thanks to Martin Schoeckle
<schoeckle@ike.uni-stuttgart.de> for sending these.
* ace/config-osf1-3.2.h: Updated this file with fixes for OSF/1 by
Martin Schoeckle <schoeckle@ike.uni-stuttgart.de>.
* ace/ACE.cpp (handle_timed_complete): Added new logic to
ACE::handle_timed_complete() so that it sets errno to
ECONNREFUSED if the connection is refused by the server. When
you issue an asynchronous connect request, to complete it, you
will use complete() with a timeout. However, complete can fail,
and then it will deallocate any resource, (i.e. close down the
socket handle), also for timeout expiration. So, a user
interested in retrying to complete a connection while the
timeout expires will not use complete(); but rather will use
handle_timed_complete(). In fact, using handle_timed_complete()
the user could detect the reason of a failure (by examining
errno) and decide how to proceed. In the old ACE version the
problem was that, if handle_timed_complete() failed because of
the recv() returning 0, errno remained unchanged and so its
value could be quite misleading with respect to the reasons of
the failure. Thanks to Antonio Tortorici
<antonio@rh0011.roma.tlsoft.it> for this fix and the explanation
above.
* ace/OS.h: Added support for Borland 5.0's uint64. Thanks to
Hani Yakan <hani@i-online.com> for suggesting the strategy to
accomplish this.
Mon Aug 19 15:52:07 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* tests: Added new macros to the test_config.h file in order to
simplify the testing.
Mon Aug 19 00:21:22 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* Re-released version 4.0.28 for testing (will change the version
number after Tim gives me the new Token stuff).
* {netsvcs/lib,tests/test_config.h}: Removed spurious dependencies
on fstream.h and iostream.h. Thanks to Alan Stewart
<axs2@osi.com> for reporting this.
Sat Aug 17 17:25:49 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/Reactor: Removed the use of "inline" in the Reactor.cpp
files because this was causing problems with some
compilers/linkers. Thanks to Gonzalo Diethelm
<gonzo@ing.puc.cl> for recommending this.
* examples/Misc/test_XtReactor1.cpp: Added a new test of the
XtReactor, courtesy of Eric Newton <ecn@clark.net>.
* ace/config-hpux-10.x.h: According to Eugene K. Plaude
<jec@r-style.msk.su>, HP-UX 10.01 supports user-level threads
based on the pthreads interface specified by POSIX in 1003.4a,
Draft 4 (which is basically DCE threads). Therefore, I've
enabled the ACE_HAS_DCETHREADS symbol in the config-hpux-10.x.h
configuration file. If this isn't correct, please let me know.
Sat Aug 17 02:18:39 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu)
* examples/Tokens/manual/README: Added a new Token example
application. The manual test gives users a text-based
interactive interface to local or remote tokens. This is
extremely useful for manually testing the token server and
setting up deadlock scenarios. See the README file for more
details.
* examples/Tokens/deadlock/README: Updated the deadlock example
application to test the new deadlock detection algorithm for
readers/writer locks. I also added the use of Token Invariants
to ensure correctness of the mutexes and readers/writer locks.
See the README file for more details.
Fri Aug 16 22:16:05 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu)
* ace/Token_Manager.cpp: Updated all Token code to use
ACE_OS::last_error instead of errno.
Fri Aug 16 00:03:24 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* After a long hiatus, released version 4.0.28 for testing.
Thu Aug 15 21:04:35 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* man: Updated all the ACE manual pages and html pages to reflect
recent changes.
* netsvcs/lib/Server_Logging_Handler.cpp: Fixed an omitted
"ACE_BUILD_SVC_DLL" that was causing linker errors on NT.
Thanks to Luca Priorelli <lucapri@mbox.vol.it> for reporting
this.
* examples/Log_Msg/test_log_msg.cpp: Added a test for the new
log_hexdump() function.
* ace/Log_Msg.cpp (log_hexdump): Integrated the log_hexdump() code
into the ACE Log_Msg abstraction. Thanks to Luca Priorelli
<lucapri@mbox.vol.it> for fixing this and for Todd Montgomery
for originally supplying the code.
* ace/Signal.cpp (ACE_Sig_Handlers): Moved the #endif /* HPUX */
down to the end of the file so that it works correctly on HPUX.
Thanks to Eric C. Newton <ecn@clark.net> for report this bug.
* ace/OS.i: Updated the behavior of thr_join() so that it will do
a ::CloseHandle after getting the exit status. Thanks to the
ever vigilant James Mansion
(mansionj@lonnds.ml.com) for noticing this.
* examples: Finally added Tim and Prashant's examles/OS directory,
which contains a test that illustrates a "portable" means to
spawn processes on NT and UNIX.
* ace/Malloc_T.cpp (next): Added an overloaded next() method that
returns the name that is bound to the pointer in the
Malloc_Iterator. This is useful in order to differentiate
entries in the pool based on their name. Thanks to Kim Gillies
<gillies@noao.edu> for suggesting this.
* ace: Changed all uses of thread_t, thread_key_t, mutex_t,
rwlock_t, sema_t, cond_t, etc. to ACE_* in order to avoid
polluting the name space. Also switched from using macros to
using typedefs whereever possible. Thanks to Gonzalo Diethelm
<gonzo@ing.puc.cl> for recommending this.
* ace/System_Time.cpp: Added template specializations for
templates used in the ACE_System_Time class. This should solve
some nasty undefined templates problems with GCC... Thanks to
Joseph DeAngelis <bytor@faxint.com> for pointing out the
problem.
* ace/Name_Space.cpp: Fixed the file Name_Space.cpp as follows:
// Name_Space.cpp
#define ACE_BUILD_DLL
//#include "Name_Space.h"
#include "ace/Name_Space.h"
Thanks to Eugene K. Plaude <jec@r-style.msk.su> for fixing this!
* ace/config-hpux-10.x.h: Added support for TLI since according to
Eugene K. Plaude <jec@r-style.msk.su> this should work. If not,
please let me know.
Wed Aug 14 21:29:46 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* examples/Reactor/Logger: rearranged the Logger directory so it
would be more clear what the client and server programs did and
how to run them.
* examples: Merged the contents of the SVR4 examples directory
into the IPC_SAP/SOCK_SAP directory so that we can remove the
SVR4 directory altogether (it wasn't contributing much...).
* examples: Removed the vestigal Win32 tests since ACE now runs on
Win32 and we don't need a separate test directory.
* netsvcs/client: Renamed the file remaining file in this
directory to logging_app.cpp since I moved the other file to the
examples/Reactor/Logger directory.
* ace/Reactor.cpp (check_handles): If eh->get_handle() returns -1
the select() code will index the [-1] element of an array. To
fix this, I've added a check of the value returned from
eh->get_handle(). Thanks to Eric C. Newton <ecn@clark.net> for
reporting this.
* ace/OS.i (sema_wait): Fixed a subtle bug in the Pthreads
wrappers that surfaced on the SGI IRIX 6.2 port. There was some
code that looked like this:
pthread_cleanup_push();
int result = 0;
...
pthread_cleanup_pop();
return result;
However, on Irix 6.2, the push introduces a new scope that is
closed by the pop, so result goes out of scope before returning.
Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl> for pointing this
out.
* ace/OS.h: Changed the definition of pthread_mutex_t and
pthread_cond_t to mutex_t and cond_t to be consistent with other
usage in ACE. Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl> for
pointing this out.
Wed Aug 14 01:25:47 1996 <harrison@samba.cs.wustl.edu>
* ace/SPIPE_Acceptor.cpp: Added the PIPE_TYPE_MESSAGE |
PIPE_READMODE_MESSAGE flags to CreateNamedPipe pipe options so
that data is received in messages rather than as a stream. This
is consistent with the behavior of the SPIPE_Connector. When we
have time, we need to extend the interface so that stream pipes
are also supported, as well.
* SPIPE_Acceptor.cpp: Made the ACE SPIPE in and out buffer sizes
10 k. The previous size was just 512 bytes. This larger buffer
size helps decrease flow control.
Tue Aug 13 23:21:46 1996 <harrison@samba.cs.wustl.edu>
* examples/Connection/blocking: Updated the blocking SPIPE example
application to use a pool of threads in the proactor to handle
incoming client messages. The SPIPE-acceptor example
illustrates how named pipes are used on NT. Once the server
establishes a connection to a single client, it spawns a thread
pool to handle incoming requests via the proactor event
loop. That is, a separate thread from the pool is used to
process each message sent by a client. The size of the thread
pool can be specified by command-line arguments. This example
leverages the queueing performed by the NT kernel to trivially
implement a thread pool architecture. See
examples/Connection/blocking/README for more details.
* Service_Config.h: Added a <thread> parameter (with a default
size of 0) to the proactor accessor method. This allows
applications to specify the size of the thread pool that can
block on Proactor::handle_events.
Tue Aug 13 02:30:58 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/Task: Added a new public interface called thr_count(). This
returns a count of the number of threads running within a Task.
If the value returned is 0, then the Task is a Passive Object.
If the value returns is > 0 the task is an Active Object, and
the value is a count of the number of threads running within the
object at this snapshot of time.
* ace/OS: I implemented Karlheinz's suggested optimizations for
the ACE condition variable implementation under Win32. Here's
the deal... The original implementation used an internal_mutex
to ensure that access to the count of the number of waiters was
serialized between the waiter and signaler threads. The new
implementation is designed so that only the waiter threads
access the waiter count. Therefore, we can utilize the
external_mutex to serialize access to this, thus eliminating the
need for the internal_mutex. However, this means that code
*must* be written using the standard condition variable idiom,
i.e.,
int resources ()
{
external_mutex.acquire ();
// ...
cond.signal ();
external_mutex.release ();
}
Rather than like this:
int resources ()
{
external_mutex.acquire ();
// ...
external_mutex.release ();
cond.signal ();
}
which is what some thread programming books recommend as an
optimization. However, you should be careful not to use this
form since it can lead to "lost wakeup" bugs caused by the fact
that the implementation of ACE_OS::cond_signal will test if the
waiter count > 0 *without holding any locks*!!!
Fortunately, ensuring this shouldn't be a problem since most ACE
code uses the following idiom:
int resources ()
{
ACE_Guard mon (external_mutex);
// ...
cond.signal ();
// Destructor of mon releases external_mutex.
}
Clearly, there are subtle tradeoffs between performance and
programmability here...
* ace/Synch: Updated all of the ACE semaphore wrappers to take the
new "max" value as their final constructor argument.
* ace/OS: Added a new default argument to the end of the
sema_init() method. This allows us to specify the maximum value
of the semaphore (this is only important on NT). Currently, it
is hard-coded to 0x7fffffff in uses. The new approach makes it
possible to set the max to a different value. Thanks to
Karlheinz for requesting this.
* ace/Message_Queue.cpp: Added an implementation of the dump().
Thanks Karlheinz.
* ace/Synch.cpp: Added an implementation of the dump() method.
Thanks Karlheinz.
* ace: Updated all usage of ACE_Thread_Mutex_Guard so that it now
uses the ACE_GUARD* macros correctly. Thanks to Chris Eich
<Chris_Eich@optilink.optilink.dsccc.com> for pointing out the
need for this.
* examples/Threads: Added Karlheinz's new test_barrier2.cpp test
program that makes sure that the ACE_Message_Queues are working
correctly when accessed by multiple threads.
* netsvcs/lib/Server_Logging_Handler.cpp (handle_logging_record):
Fixed an errant use of ACE_Guard, which wasn't properly checking
of the Guard acquired the lock. Thanks to Chris Eich
<Chris_Eich@optilink.optilink.dsccc.com> for pointing this out.
* ace/OS.h (ACE_GUARD): Added default "ace_mon" implementations of
type ACE_Null_Mutex even in cases where there's no threading
defined so that code accessing ace_mon.release() and
ace_mon.acquire() will compile correctly.
* apps/Gateway/Gateway/Channel.h: Fixed the code so
that we don't try to use TLI if the platform doesn't support it
(instead, we'll use sockets). Thanks to Marius Kjeldahl
<marius@funcom.no> for reporting this problem.
* examples/ASX/Event_Server/{Supplier,Consumer}: Fixed the code so
that we don't try to use TLI if the platform doesn't support it
(instead, we'll use sockets). Thanks to Marius Kjeldahl
<marius@funcom.no> for reporting this problem.
Mon Aug 12 14:50:47 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* examples/Misc: Added Eric Newton's <ecn@clark.net> test case for
his XtReactor integration.
* ace: Included Eric Newton's <ecn@clark.net> code that integrates
ACE with the Xt event loop. This still needs a bit of work
(e.g., making it thread-safe and incorporating signal support), so
I haven't added it to the Makefile yet. If someone can take the
time to fix it up, I'll be happy to integrate it into ACE.
* ace/Message_Queue.cpp (dequeue_head): Fixed the mother of all
bugs in the ACE_Message_Queue implementation... The problem was
that I was trying to be too clever by optimizing the number of
Condition::signal() calls by only calling signal() when the
queue changed state from empty to non-empty (or full to
non-full). It turns out that this optimization works fine for a
single producer/consumer case, but fails when there are multiple
consumers. The fix was just to call signal() every time. This
should be ok because the underlying Condition variable
implementation will perform the optimization in the correct
fashion. Thanks to the omniscient Karlheinz for detecting this
problem and reporting it.
Sun Aug 11 15:52:07 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* tests: Made minor changes to test_config.h, SPIPE_Test.cpp, and
UPIPE_SAP_Test.cpp to accomodate the change made to SPIPE_Addr.
SPIPE_Addr now accepts a string of the form [host:]port and then
creates the rendezvous point. Originally, SPIPE_Addr would
assume that the string being passed in was the actual rendezvous
point.
Sat Aug 10 18:41:21 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* netsvcs/lib/Logger.cpp (init): Added a new service to netsvcs
called ACE_Logger which allows us to control the output of all
the services. The ACE_Logger service can be invoked with
different flags (such as STDERR|OSTREAM) which in turn sets
ACE_Log_Msg to direct the output of all the services to the
appropriate stream(s). Note that if a service needs to stay
unaffected from ACE_Logger, it should be invoked before
ACE_Logger gets invoked. Also note that like other services in
netsvcs, ACE_Logger can also be dynamically linked in.
Sat Aug 10 14:23:07 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* Added Steve Huston's <shuston@ultranet.com> patches to get ACE
to compile on UnixWare 2.01. This mostly involved changes to
the internal types used by the socket wrappers. Thanks Steve!
Fri Aug 9 01:34:19 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* examples/ASX/UPIPE_Event_Server/Options.cpp (print_results):
Added a typedef to avoid problems if a platform doesn't support
prusage_t. Thanks to Marius Kjeldahl <marius@funcom.com> for
reporting this.
* include/makeinclude/platform_linux_pthread.GNU. The line that
say:
LIBS = -lpthreads -lstdc++
was modified to say:
LIBS += -lpthreads -lstdc++
Thanks to Marius Kjeldahl <marius@funcom.com> for reporting
this.
Fri Aug 9 18:26:16 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* ace/Local_Name_Space.cpp (reset): Fixed a subtle (yet very
annoying bug). In switching contexts a test program would hang
after a certain number of switches. Having gone through the code
thoroughly and with the aid of Purify, the bug was narrowed down
to an extraneous delete taking place in
ACE_Name_Space::reset(). Essentially, we do not need to delete
ACE_Name_Space_Map::instance() which is actually the
SHARED_MALLOC since it gets deleted in the destructor of
ACE_Local_Name_Space.
Thu Aug 8 17:55:20 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* ace/SPIPE_Addr.cpp (set): Implemented
ACE_SPIPE_Addr::string_to_addr(). Modified ACE_SPIPE_Addr::set()
using code provided by Brad Flood to create the rendezvous
point. Note that originally ACE_SPIPE_Addr constructor and set()
would take the actual rendezvous point but now they rely on
being passed a string which is of the format "[host]:port"
(where host is optional). The rendezvous point is then created
by extracting from the string the hostname (if any) and also
using the port number as the unique pipe name. Note that this
approach works on both UNIX and Win32.
Mon Aug 5 20:15:59 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* ace/OS.i (last_error): Fixed a typo. In the set and get methods
last_error(), there should be a check for "if defined
(ACE_WIN32)" and not "if defined (ACE_HAS_WIN32)"
Wed Aug 7 00:21:42 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/Log_Msg.h: Replaced all uses of errno *following calls to
ACE_Log_Msg::instance()* so that we first cache errno in a local
variable called __ace_errno. We need to do this because
ACE_Log_Msg::instance() can reset errno == 0. Thanks to
Tim for pointing this out.
Mon Aug 5 20:15:59 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* ace/OS.i (last_error): Fixed a typo. In the set and get methods
last_error(), there should be a check for
"if defined (ACE_WIN32)" and not "if defined (ACE_HAS_WIN32)"
Sat Aug 3 14:52:32 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* examples/Win32/win32_client.cpp: Changed ACE_GUARD_RETURN to
ACE_GUARD in the method Errno::flags since the return type is
void.
* examples/Connection/non_blocking/CPP-connector.cpp: Made some
minor changes to get things compiling on Win32. The call to
handle_close now takes zero as the first argument (which is
never used). Also the arguments to ACE_SERVER_ADDRESS are now
swapped (hostname followed by port number) to be consistent with
the change made to the macro. Thanks to Brad Flood for
suggesting these changes.
* examples/Connection/non_blocking/CPP-acceptor.cpp: Made minor
changes to some of the methods to make sure all control paths
return a value. Also changed the default port number to
ACE_DEFAULT_SERVER_PORT_STR to match what the connector tries to
connect to. Thanks to Brad Flood <BFLOOD@slc.unisysgsg.com> for
suggesting these changes.
* ace/OS.h (ACE_SERVER_ADDRESS): Modified the macro
ACE_SERVER_ADDRESS so that it creates a string of a server
address with a "host:port" format. Previously the order was
reversed. Thanks to Brad Flood for suggesting this change.
Sat Aug 3 00:07:26 1996 Douglas C. Schmidt (schmidt@lambada.cs.wustl.edu)
* ace: Fixed problems with recursive tracing of ACE_TRACE by
commenting out certain constructors in IPC_SAP.cpp,
FIFO_Send_Msg.cpp, FIFO_Send.cpp, and FIFO.cpp. Thanks to
Karlheinz for finding and reporting these fixes.
Fri Aug 2 22:19:05 1996 Douglas C. Schmidt (schmidt@lambada.cs.wustl.edu)
* ace/ACE.cpp (format_hexdump): Fixed an infamous "off by one" bug
that was causing this to fail on Win32 (time to switch to Java? ;-)).
Thanks to lucapri@mbox.vol.it for finding this.
Thu Aug 1 14:08:30 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/CORBA_Handler.cpp (activate_service): Fixed a typo caused by
an omitted ENDTRY. Thanks to Garrett Conaty
<gconaty@outbackinc.com> for noticing this.
Mon Jul 29 10:03:16 1996 Douglas C. Schmidt (schmidt@lambada.cs.wustl.edu)
* examples/Win32/win32_client.cpp: There was a typo in one of the
ACE_GUARD macros. Thanks to Tim Ottinger
<tottinge@csci.csc.com> for pointing this out.
Mon Jul 22 12:41:22 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* ace/Local_Name_Space.cpp (reset): Added a new method
ACE_Name_Space_Map::reset() which deletes the instance of
ACE_Name_Space_Map. This forces instance() to create a new
instance using a new context file in the case of the context
having changed. I make use of this in
ACE_Local_Name_Space::create_manager().
Fri Jul 19 12:28:07 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* ace/System_Time.cpp (get_master_system_time): Modified
ACE_System_Time::get_master_system_time() so that if an entry
for the time is not found in shared memory (indicating that no
Clerk is running), then we should just return the local time of
the host.
* netsvcs/lib/TS_Clerk_Handler.cpp (update_time): Modified
ACE_TS_Clerk_Handler::update_time() so that if the Clerk is not
connected to any servers, is sets the delta time to zero
allowing clients to then use the local time of the host.
Wed Jul 17 22:19:53 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* ace/UPIPE_Connector.cpp (connect): Added an #ifdef around the
check of ACE_OS::isastream (handle) in
ACE_UPIPE_Connector::connect() since the call is not supported
on NT.
Thu Jul 11 22:22:57 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu)
* ace/OS.i (kill): Modified ACE_OS::kill so that it works on NT.
It takes a process ID, creates a handle for the associated
process, and calls TerminateProcess on the handle. This is
actually pretty dangerous according to the NT documentation.
Can majorly confuse DLLs. Does the same old thing on UNIX.
* ace/OS.cpp (fork_exec): Added a fork_exec operation to ACE_OS.
This works on UNIX and NT. It combines the forking and exec'ing
into one call. This has to be combined since Win32
CreateProcess only starts applications from scratch (unlike UNIX
fork).
* examples/OS/test_os.cpp: Added a new example application to test
the new ACE_OS::fork_exec and ACE_OS::kill operations.
Tue Jul 9 13:04:14 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/Service_Manager.cpp (reconfigure_services): To improve
portability on Win32 and UNIX I replaced the use of a signal to
trigger reconfiguration to instead make a call to the new
ACE_service_Config::reconfig_occurred() method. This should
actually perform the same as the original approach, since all
the signal handler ever did was to set this flag! Thanks to
Karlheinz for pointing out the need for this.
* ace/Service_Config.h: Added a new static public method called
reconfig_occurred(sig_atomic_t) to set if a reconfiguration
should take place the next time through the event loop.
Mon Jul 8 14:20:01 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* ace/Time_Value.h: Added "ACE_Export" before all global operators
to allow them to be dll-exportable on NT.
Mon Jul 8 13:12:05 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/{Message_Block,DEV_IO,SPIPE_Stream}.cpp: Fixed several more
cases of delete array that should have been delete [] array.
Thanks to Tom Leith for pointing out some of these. I can hear
the ghost of James Mansion coming closer... ;-)
* INSTALL: Added tips on how to install ACE on a Win32 platform
that lacks a network card.
* ChangeLog: Split ChangeLog-96 into two files (ChangeLog-96a and
ChangeLog-96b) since it was becoming quite large! Thanks to
Chris Lahey for pointing this out.
* ace/Stream.cpp: Was missing a "return 0;" at the end of the
close() method. Thanks to Tom Leith <trl@icon-stl.net> for
finding this.
Mon Jul 8 14:20:01 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* ace/Time_Value.h: Added "ACE_Export" before all global operators
to allow them to be exportable from Win32 DLLs.
Sun Jul 7 10:34:48 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* Released version 4.0.27 for testing.
* config-sunos5.5*.h: Removed all uses of ACE_HAS_SVR4_SIGNAL_T in
the config files since Solaris 2.5 has consistent signal and
sigaction types (at last!).
* Installed and compiled ACE successfully with the new SunC++ 4.1
compiler on Solaris 2.5. However, there seems to be major
problems with the interaction of the SunC++ exception handling
runtime system and the Solaris multi-threading mechanisms. This
is causing the ACE multi-threading tests to bomb with
segmentation faults inside of the _ex_unwind() library function.
If you read the /opt/SUNWspro_3.1/READMEs/c++ file you'll see
why this problem is occurring (apparently due to bugs in the
Solaris libC.so.5 C++ runtime library).
There seem to be two fixes for this problem:
1. Add the following to *all* threads (including main):
#include <exception.h>
void *my_thread_entry_point (void *) {
set_terminate (abort);
set_unexpected (abort);
// Do real work...
}
This is the approach recommended by the README file in
SUNWspro_3.1. However, it is *clearly* a horrible hack and
very non-portable (therefore, I deem it worthy of Microsoft
;-)).
2. Compile ACE (and applications?) with -noex in order to avoid
this bug. This is clearly not desirable either since it
precludes the use of exception handling with C++ and threads
on Solaris...
Since ACE doesn't use exceptions internally on Solaris option 2
seems like the best approach for the time being. When Sun gets
it act together and releases a bug-free library and C++
software, I'll fix ACE accordingly.
* tests: Integrated the latest of Prashant's "one-button" tests
into the main ACE release. These will run on both UNIX and
Win32 now.
* ace/UPIPE_Stream.cpp (recv): Changed the semantics of the
ACE_UPIPE_Stream::recv (char *, size_t, ACE_Time_Value *)
method. Currently, the behavior is to block until *exactly* N
bytes are read. However, this is incorrect for 2 reasons:
1. It makes it hard to write a server that doesn't know
precisely how big the messages are from the client. In
particular, if the receiver doesn't know how big the buffer
messages are from the client it will block indefinitely!
2. It is redundant with respect to the
ACE_UPIPE_Stream::recv_n(), which also blocks until all N
bytes are received.
Therefore, I've made the new UPIPE_Stream::recv() method block
only until it's received the first block of data that allows it
to fulfill its size request, or anything that is smaller than
that size.
* ace/OS.cpp (thr_create): Since POSIX pthreads doesn't provide an
equivalent of THR_NEW_LWP in the pthreads_attr_* functions, I've
added an emulation that should work for Solaris. Basically, if
THR_NEW_LWP is set when ACE_OS::thr_create() is called, we use
the ACE_OS::thr_{get,set}concurrency methods to increase the
number of LWPs by one.
* ace/Message_Block: Changed the default high water mark for an
ACE_Message_Queue from 4K to 16K. This is useful since it
allows applications to buffer more information before blocking.
* ace/Log_Msg: Added a pair of operations that allow applications
to acquire and release the synchronization lock used internally
by the ACE_Log_Msg implementation. This allows applications to
hold the lock atomically over a number of calls to ACE_Log_Msg,
which is useful for composite operations like the following:
// Make sure the following operations are run atomically!
ACE_LOG_MSG->acquire ();
while (c != '!')
{
if (c_stream.recv (&c, 1) == -1)
ACE_DEBUG ((LM_DEBUG,
"(%t) buffer recv from supplier failed\n"));
else
ACE_DEBUG ((LM_DEBUG, "%c", c));
}
ACE_LOG_MSG->release ();
* examples/IPC_SAP/UPIPE_SAP: Revised all of the UPIPE_Stream
tests to make them more consistent and correct with respect to
the new changes.
* ace/Stream.cpp (link_i): There was a bug in the link_i() logic
because we weren't also linking the other stream back to our
stream.
* ace/UPIPE_{Acceptor,Connector}: Modified both of these classes
so that they don't
* ace/Stream.cpp (close): Modified close() so that it now detects
"double-closes" and ignores anything but the first one.
* ace/UPIPE_Stream: Updated this class so that it no longer
inherits from ACE_Stream (previously ACE_UPIPE_Stream had
inherited from *both* ACE_Stream *and* ACE_SPIPE). There are
several reasons we shouldn't inherit from ACE_Stream:
1. There are operations on ACE_Stream that don't make any sense
on ACE_UPIPE_Stream (e.g., link(), unlink()).
2. ACE_Stream isn't really designed to be subclassed (e.g.,
it doesn't have virtual methods).
3. Not inheriting makes the interface cleaner, e.g., we now use
send() and recv() methods consistently, rather than
send_msg()/put() and recv_msg()/get().
4. The return values from the I/O methods are now more
consistent than they were before.
* ace/Message_Block: The signature for the copy() method was
incorrect. It should have been copy (const char *, .....)
rather than copy (char *, ....).
* examples/IPC_SAP/UPIPE_SAP: Together with Prashant, fixed up the
ACE_UPIPE_Stream tests so they more cleverly
(and correctly) utilize and illustrate various ACE concurrency
features.
Sat Jul 6 18:28:55 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/Stream.cpp: Fixed some obscure bugs with Stream::unlink()
and Stream::link(). These bugs were triggered by the
ACE_UPIPE_Stream tests. We need to make sure that we don't have
race conditions in the order in which ACE_UPIPE_Stream close()
down. Prashant and I fixed this problem by (1) adding a lock to
unlink() and link() and then creating unlink_i() and link_i() to
perform the work and (2) being more careful about trying to
unlink our side and the other side of a linked Stream.
* ace/config-linux.h: According to Istvan Buki
<istvan.buki@infoboard.be>, Linux now supports the
send_msg()/recv_msg() system calls, as well as UNIX domain
sockets. Therefore, I've updated the config-linux*.h file to
remove the existing restrictions. If this turns out not to be
the case, please let me know.
* ace/LSOCK.cpp (recv_handle): Added a change to some casts to
make ACE compile with Linux. Thanks to Istvan Buki
<istvan.buki@infoboard.be> for reporting this.
* apps/Gateway/Gateway/File_Parser.cpp (readword): Removed
yet another use of:
for (int x; foo(x); )
{
}
x = 10;
Which is now a deprecated feature of C++.
* include/makeinclude: added the -lw library to the GNU G++
platform*.GNU file in order to pick up the wide-character string
functions.
Fri Jul 5 18:11:44 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* Re-released version 4.0.26 for testing.
* ace/CORBA_Handler.cpp (activate_service): Revised the code to
use the Orbix macros for TRY/CATCH rather than try/catch. We
need this to make legacy code work! Thanks to Irfan for
pointing this out.
* ace/Thread_Manager: Fixed a bunch of typos that grelims snuck
in. Thanks to Jack Erickson <jack@cibc.com> for reporting this.
* examples/IPC_SAP/TLI_SAP/ftp-server.cpp: Fixed some typos that
were causing problems on AIX. Thanks to Greg Wilson
<gvwilson@vnet.ibm.com> for reporting this.
* examples/Reactor/Misc/test_time_value.cpp (operator<<): Added a
"const" in front of the ACE_Time_Value & in order to make things
work correctly on AIX. Thanks to Greg Wilson
<gvwilson@vnet.ibm.com> for reporting this.
* ace/SPIPE_Acceptor: Fixed some missing "returns" that had sprung
up in the #else arm of the SPIPE code. Thanks to Greg Wilson
<gvwilson@vnet.ibm.com> for reporting this.
* apps/Synch-Benchmarks/Benchmark: Fixed a typo that was causing
the application to fail to compile on AIX. Thanks to Greg
Wilson <gvwilson@vnet.ibm.com> for reporting this.
* Changed all uses of virtual int init (int, char **) to virtual
int init (int, char *[]) to workaround bugs with MSVC++...
* ace/OS.h: for POSIX pthreads, changed the definition of the
THR_SCOPE_SYSTEM macro so that it has the same value as
THR_BOUND. If this isn't done, then things don't quite work
right when we implement the ACE_OS::thr_create() wrapper.
Thu Jul 4 13:17:35 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/Thread_Manager: Added a new method called thr_self() that
*does* return a real handle that can be used by
WaitForMultipleObjects, etc. Note that this new approach
cleverly caches this handle in TSS in order to cut down on
search time. Thanks to Jesper for pointing this technique out.
* ace/OS.i (thr_self): After receiving comments from Jesper, undid
the earlier change today that was returning a duplicated handle
for ACE_OS::thr_self(). It turns out this is a bad idea because
the handle most typically doesn't get released, which leads to
handle leaks.
* ace/Thread_Manager: Added a new private method called
check_state(). This method extends existing code to be smarter
about how we check to see what "state" (e.g., suspended,
cancelled, etc.) a thread is in. The original code
(which was a macro called ACE_CHECK_STATE) didn't behave
correctly if we asked about the state of a thread that was
different from ourselves!
* ace/Thread: Modified the public interface to
ACE_Thread::spawn_n() so that it now takes a void *stack[] and
size_t stack_size[]. If stack != 0 it is assumed to be an array
of n pointers to the base of the stacks to use for the threads
being spawned. Likewise, if stack_size != 0 it is assumed to be
an array of n values indicating how big each of the
corresponding stacks are. This is useful since now we can spawn
a group of threads each of which has its own custom stack and/or
stack size. Thanks to Ashish Singhai
<singhai@delirius.cs.uiuc.edu> for pointing out the need for
this.
* apps/Synch-Benchmarks: Updated the Synch benchmarks so that most
of them work again. The trick is *not* to use ACE_OS::sleep ()
(which doesn't seem to be thread-friendly...) but instead to use
ACE_OS::select() as a timer.
* man: updated the manual pages and html pages to reflect all the
recent changes.
* ace/Malloc_T.cpp (open): Added a check to make sure that if
init_acquire() fails we don't let this go by undetected...
Thanks to Karlheinz for pointing out the need for this.
* ace/OS.i (thr_getconcurrency): Fixed a subtle bug with the
ACE_OS::thr_getconcurrency() function. I was mistakenly using
ACE_ADAPT_RETVAL for the result of ::thr_getconcurrency(), which
is clearly wrong!
* ace/Service_Record.cpp (remove): Fixed a typo that was causing
the removals of Modules in a dynamically configured Stream to go
into infinite loops.
* ace/OS.i (thr_self): Modified the ACE_OS::thr_self (hthread_t &)
function so that it will return a *duplicate* of the current
thread's pseudo-handle returned by GetCurrentThread(). This
change is necessary because the pseudo-handle returned by
GetCurrentThread() is pretty useless (e.g., it can't be used by
any other thread to "wait" for this thread to exit). This new
behavior is used in the examples/Reactor/ReactorEx test program.
* ace/Service_Config.cpp: I'd forgotten to assign the
delete_svc_rep_ flag when dynamically allocating the svc_rep_.
This is fixed now.
Wed Jul 3 20:09:44 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* Added a new subdirectory called $WRAPPER_ROOT/tests that
contains the first phase of the ACE regression tests.
* ace/Reactor.cpp (check_handles): Fixed an earlier fix with the
ACE_Reactor::wait_for_multiple_events() method. The earlier fix
had changed the exit condition of do/while loop to be
while (nfound == -1 && this->handle_error () >= 0);
However, this was causing signal handling to break...
Therefore, the right fix is to keep the exit test as:
while (nfound == -1 && this->handle_error () > 0);
and instead fix handle_errors() so that it returns 1 if we're
able to fix a bad handle... Thanks to Prashant and Irfan for
tracking this down.
* ace/OS: Finally broken down and added a new pair of ACE_OS
functions called "last_error()". These basically call
SetLastError/GetLastError on Win32 or they set/get errno on
UNIX.
* ace/config-linux.h: Fixed an annoying problem with
struct msghdr in Linux by adding
#define msg_accrights msg_control
#define msg_accrightslen msg_controllen
to the config-linux*.h files. Thanks to Michael R"uger
<m_rueger@syscomp.de> for suggesting this.
* ace/SOCK_IO.cpp (recv): Fixed a "bug" where
ACE_SOCK_IO::{send,recv} allocates with:
iovec *iovp = new iovec[total_tuples];
But deletes with:
delete iovp;
Thanks to the ever vigilant James Mansion
(mansionj@lonnds.ml.com) for noticing this.
Tue Jul 2 23:48:38 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu)
* ace/Service_Config.h: Added ReactorEx to the singleton resources
that the Service_Configurator holds. This includes accessors,
destruction hooks, and event loop methods.
* examples/Reactor/ReactorEx/README: There is a new example
application for the ReactorEx. Please check out
examples/Reactor/ReactorEx/README for details.
Tue Jul 2 18:43:12 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* Released version 4.0.25 for testing.
* examples/ASX/Message_Queue/priority_buffer.cpp: Added a new test
program that illustrates the use of the new Message_Queue
priority scheme.
* ace/Message_Queue: Added new support for prioritized message
enqueueing into the ACE_Message_Queue. Now, when an application
uses ACE_Message_Queue::enqueue() the new Message_Block is
inserted into the queue according to its msg_priority(). When
dequeue_head() is used the item retrieved will then be the item
of "highest priority" (priorities range from 0 to MAX_LONG).
Note that the semantics of the existing enqueue methods,
enqueue_head() and enqueue_tail(), remain unchanged.
* ace/Message_Block: Changed the type of the priority in a message
block to u_long rather than u_char. This gives us a much
greater range of priorities!
Mon Jul 1 01:12:08 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu)
* ace/Thread.h: Changed a couple of mistyped comments. Thanks
to the eagle eyes of Andres Kruse for noticing this.
* ace/OS: added more comprehensive support for UNICODE to
both the Win32 and UNIX OS adaptation layer. This new
support automagically selects the appropriate implementation
(i.e., either char * or wchar_t *) for the string comparison
routines (which are used in places like ACE_Mem_Map).
* ace/Service_Config: Split up the ACE_Service_Config::close()
method into two parts: close_svcs() and close_singletons().
This makes it possible to remove svc.conf services without
destroying Singletons like the Proactor, Reactor, etc. Thanks
to Karlheinz for recommending this.
* ace/Service_Config: Added flags for remembering who created the
Singleton Proactor, Allocator, Thread_Manager, and
Service_Repository (in addition to the Reactor, which I did last
week). If we created these Singletons, then we are responsible
for freeing them up. Thanks to Karlheinz for pointing out the
need for this.
Mon Jul 1 16:26:27 1996 Prashant Jain (pjain@merengue.cs.wustl.edu)
* ace/Connector.cpp: Added two new arguments to connect () namely,
"int flags" and "int perms". The Connector can now pass these
two arguments to its template arguments (e.g., SOCK_Connector,
SPIPE_Connector, etc.) when calling their connect() method. A
consequence of doing this was that we had to modify the
signature of the connect() method on some of the IPC_SAP classes
(e.g., TLI_Connector, SOCK_Connector, and LSOCK_Connector).
Note that these changes may break some existing code,
particularly with TLI_Connector (see below), so beware...
* ace/TLI_Connector.cpp: Changed the order of the connect()
arguments to be more consistent with the rest of the IPC_SAP
classes used with the Connector. Please note that existing
examples which use TLI_Connector may need to be modified as a
result of this change.
* ace/OS.i (open): Modified ACE_OS::open() to use the argument
perms to turn the flag FILE_FLAG_OVERLAPPED on and off for
Win32.
* ace/Service_Config.cpp (end_proactor_event_loop): Added new
methods run_proactor_event_loop() and end_proactor_event_loop()
which call handle_events on the Proactor.
Mon Jul 1 02:15:34 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu)
* ace/Proactor.h: Made ACE_Proactor an ACE_Event_Handler so that
it can be registered with the ACE_ReactorEx. ACE_Proactor
associates the same global HANDLE with every overlapped I/O
operation. This global HANDLE can be registered with the
ACE_ReactorEx. Therefore, by using the
ACE_Proactor::handle_signal method as an adapter, we can now
dispatch overlapped I/O and other "waitable" objects from a one
ACE_ReactorEx running in a single thread of control. Thanks to
James Mansion <mansionj@lonnds.ml.com> for setting us on the
right path!
* ace/ReactorEx.h: Added a ACE_ReactorEx to encapsulate Win32
WaitForMultipleObjects(). The ACE_ReactorEx handle_events()
method calls ACE_Event_Handler::handle_signal when the
corresponding Win32 HANDLE becomes signaled. This gives us a
uniform abstraction for dispatching all "waitable" objects on
Win32, including events related to I/O completion ports and
events related to other forms of NT synchronization (such as
mutexes, semaphores, threads, etc.).
* ace/Timer_Queue.h (calculate_timeout): Added a calculate_timeout
method to ACE_Timer_Queue. Also removed the same method from
ACE_Reactor. This is so Reactor, ReactorEx, and Proactor can
all reuse the calculations required by the Timer_Queue without
duplicating code.
