Thu Jan 2 00:42:21 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* examples/ASX/Event_Server: Completely rewrote and retested the
ACE Event Server example. The new code is *much* easier to
understand, has many more comments, is more robust, and compiles
much faster since I removed many of the templates.
* examples/ASX/Event_Server/Tranceiver/tranceiver.cpp: Fixed the
tranceiver so that it shuts down correctly when the Event_Server
exits.
* examples/Connection/non_blocking/CPP-connector.cpp: Fixed a
problem where we were trying to select() on ACE_STDIN on Win32.
Naturally, this doesn't work, so we used the
ACE::register_stdin_handler() to fix this. Thanks to
Samuel_Bercovici <Samuel_Bercovici_at_EFT__AD2@mail.icomverse.com>
for reporting this.
* examples/ASX/Event_Server/Event_Server/Options: Changed the
Options class to be a Singleton...
* ace/Task.h: Added "const" method qualifier to accessor methods
like is_reader() and is_writer().
Wed Jan 1 00:10:47 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu>
* ace/Message_Block: Added a new static release() method that
behaves like the non-static method release(), except that it
checks if <mb> is 0. This is similar to CORBA::release(), which
is useful if you want to eliminate lots of checks for NULL
pointers before calling release() on them.
* Updated all places in ACE where we use
ACE_Event_Handler::READ_MASK when we should be using
ACE_Event_Handler::ACCEPT_MASK.
* examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp:
Changed the name of the acceptor class from Handle_Thr_Stream to
Handle_Thr_Acceptor, which is more accurate.
* ace/Reactor: Since we've now got an
ACE_Event_Handler::ACCEPT_MASK (intended primarily to accept
connections asynchronously using Win32 overlapped I/O) we can
now use this with the ACE_Reactor, as well. In particular, any
time that we are registering a "passive-mode" socket acceptor we
can now specify ACE_Event_Handler::ACCEPT_MASK. This is much
more intuitive than using the READ_MASK (which never made any
sense...). The ACE_Reactor now treats the ACCEPT_MASK as a
READ_MASK internally, so you can still use READ_MASK if you'd
like (i.e., this change doesn't break any existing code).
* ace/Event_Handler: Changed "get_priority" and "set_priority" to
simply "priority(void)" and "priority(int)" to be more
consistent with other parts of ACE.
* apps/Gateway/Gateway: Updated the Gateway so that the
concurrency strategies can now be specified on the
command-line (or in the svc.conf file), rather than being
determined at compile-time. This is much more flexible.
See the ./apps/Gateway/Gateway/README file for details.
* apps/Gateway/Gateway: Verified that all the multi-threading
strategies still work.
* ace/Message_Block.cpp (ACE_Message_Block): Make sure that we
"release" the continuation field, rather than delete it, since
its reference count may be > 1.
* ace/Log_Msg.cpp (log): Change the abort_prog logic a bit so that
we always print a message to stderr if we're exiting,
regardless... Thanks to David Levine for pointing this out.
* apps/Gateway/Gateway: Moved all of the configuration file
parsing logic *outside* of the Event_Channel into the Gateway
class so that we wouldn't have unnecessary dependencies.
* apps/Gateway/Gateway: Redesigned the Gateway so that the
Proxy_Handlers (i.e., the Consumer_Proxy and Supplier_Proxy)
most of their work to the Event_Channel. This "lightweight
proxy" design is an improvement since it is now possible to
emulate the COS Event Channel semantics within the Event_Channel
"kernel."
* Happy new year! Let's start a new ChangeLog to celebrate the
new year.
