Some of the thread support code (threads.c, coop.c, etc.) used to live
in a separate directory called threads. In April 1997, that dir was
merged with libguile; this is the ChangeLog from the old directory.
Please put new entries in the ordinary ChangeLog.
Mon Feb 24 21:48:12 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* configure.in: Added AM_MAINTAINER_MODE
Fri Feb 21 23:52:16 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* Makefile.am (modincludedir, modinclude_HEADERS): Added until
libthreads is integrated into libguile, otherwise people who try
to use Guile from an independent application will have trouble
finding libguile/../threads/threads.h.
Sat Jan 11 18:35:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
* Makefile.am (noinst_HEADERS): Added coop-defs.h so that it gets
distributed.
Tue Jan 7 14:05:35 1997 Mikael Djurfeldt <mdj@kenneth>
* coop-defs.h: Added includes which define `time_t'.
Sun Jan 5 15:07:07 1997 Jim Blandy <jimb@floss.cyclic.com>
* Makefile.am (EXTRA_DIST): Add .cvsignore.
* Makefile.am (libthreads_a_SOURCES): Add threads.h. I think this
is right...
(noinst_HEADERS): Remove it from here.
* Makefile.in: Rebuilt.
Thu Jan 2 15:15:16 1997 Mikael Djurfeldt <mdj@kenneth>
These changes separates threads declarations which everybody wants
to see (coop-defs.h) from declarations internal to the threads
module (coop-threads.h), thereby solving the "-I ../qt" problem.
(This is not the final solution. All files in the threads
directory should be moved into libguile since 1. it is too tightly
interconnected with libguile internals to be a separate module and
2. it is actually quite small. When doing this, things can be
organized in a more natural way.)
* coop-defs.h: New file.
* coop-threads.c: Added #include "coop-threads.h"
* coop-threads.h: Moved coop_t struct and threads macros to
coop-defs.h. Added #include "coop-defs.h".
* threads.h: Changed #include "coop-threads.h" --> #include
"coop-defs.h".
Mon Dec 9 17:20:39 1996 Tom Tromey <tromey@cygnus.com>
* Makefile.am (.c.x): Use guile-snarf.
(INCLUDES): Search for headers in libguile source and build
directories.
Mon Dec 2 20:37:07 1996 Tom Tromey <tromey@cygnus.com>
* PLUGIN/greet: Removed.
* Makefile.am, aclocal.m4: New files.
* configure.in: Updated for Automake.
Sun Nov 10 18:21:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
* Makefile.in (uninstall_threads): rmdir -f isn't portable;
use rm -rf instead.
Sun Nov 10 17:41:21 1996 Jim Blandy <jimb@floss.cyclic.com>
* Makefile.in, configure.in: When threads are disabled,
short-circuit the `install' and `uninstall' Makefile targets too.
Sat Nov 2 21:29:33 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* threads.c: Added #include "dynwind.h".
Added scheme level procedure `single-active-thread?'.
* mit-pthreads.c, mit-pthreads.h: Port completed but untested.
* coop-threads.h: Increased SCM_THREAD_SWITCH_COUNT from 10 to 50
to decrease overhead at the cost of granularity.
* coop.c, coop-threads.h: Made coop_global_runq and
coop_global_sleepq visible globally.
* coop-threads.c (scm_single_thread_p): New function.
Thu Oct 24 22:37:03 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* threads.c: #include "dynwind.h"
* coop-threads.c (scm_threads_mark_stacks): Removed unused
variable.
* coop.c (coop_qput, coop_all_qput, coop_all_qremove): Removed
unused variable.
Wed Oct 9 19:46:00 1996 Jim Blandy <jimb@floss.cyclic.com>
* Makefile.in: Doc fixes.
* Makefile.in (ancillary): Corrected spelling from `ancillery'.
* Makefile.in (source, h_files, ancillary): Updated to describe
the actual contents of the tree.
(PLUGIN_distfiles): New variable.
(dist-dir): New target, to create a sub-tree of a distribution.
* Makefile.in (all): Depend on @target_all@ instead of
libthreads.a, so the configure script can make this makefile do
nothing when threads aren't in use.
* configure.in: If we using cooperative threads, then let
@target_all@ expand to libthreads.a; otherwise, let it expand to
the empty string.
Sat Oct 5 18:40:09 1996 Mikael Djurfeldt <mdj@kenneth>
* threads.c, threads.h (scm_init_threads, scm_threads_init): Added
stack base pointer argument so that main thread can be initialized
properly.
* configure.in: Added lines to set default -g flag in CFLAGS and
LDFLAGS.
* coop-threads.c: Added argument checking to scheme level
procedures. Change the way threads are launched.
* threads.h: Added #include "procs.h"
Added macros SCM_THREADP, SCM_MUTEXP and SCM_CONDVARP.
Wed Oct 2 14:36:44 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
* coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
scm_threads_free_condvar): free --> scm_must_free
* coop-threads.h: Added macros SCM_THREAD_LOCAL_DATA and
SCM_SET_THREAD_LOCAL_DATA.
Tue Oct 1 00:05:54 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
* coop-threads.c (scm_threads_mark_stacks): scm_save_regs_gc_mark
is already in root state (should it really?). Don't allocate it
locally; Remove extra argument to scm_mark_locations.
* coop-threads.h: Changed #include <qt.h> --> #include "../qt/qt.h"
(SCM_THREAD_INITIALIZE_STORAGE, SCM_DEFER_INTS, SCM_ALLOW_INTS,
SCM_REDEFER_INTS, SCM_REALLOW_INTS, scm_coop_create_info_type):
Removed; Declaration of scm_coop_create_info removed. Added
definition of SCM_THREADS_SWITCHING_CODE.
* coop-threads.c: Removed gscm_type objects. Renamed all
gscm_threads_<type>_die --> scm_threads_free_<type> and let them
return freed size as smob freeing code normally does. Removed
thread creation mutex and thread creation info structure.
(gscm_threads_thread_equal, gscm_pthread_delete_info,
scm_threads_init): Removed.
(scm_threads_init_coop_threads): Removed allocation of thread
local data. Removed initialization of thread creation mutex.
Renamed scm_threads_init_coop_threads --> scm_threads_init.
(scm_threads_mark_stacks): Mark root object instead of local
protects.
(launch_thread): thunk and handler is passed as a scheme list.
Call scm_with_new_root instead of scm_with_dynamic_root. Let
scm_with_new_root care about thread local variables. Removed
unlocking of creation mutex.
(scm_call_with_new_thread): Remove initialization of create info
structure and locking of creation mutex. Do smob allocation.
(scm_join_thread): Extract thread data in a new way.
(scm_make_mutex): Do smob allocation.
(scm_lock_mutex, scm_unlock_mutex): Extract thread data in a new
way.
(scm_make_condition_variable): Do smob allocation.
(scm_wait_condition_variable, scm_signal_condition_variable):
Extract thread data in a new way.
* threads.c: Don't use files "no-threads.[hc]". Removed old code
for creation of thread, mutex and condition-variable objects.
Added smobs instead. Use scm_threads_free_<type> for freeing.
(scm_init_threads): Moved scm_add_feature ("threads") to
feature.c.
* threads.h: Added declaration of scm_init_threads. Added macro
selectors SCM_THREAD_DATA, SCM_MUTEX_DATA and SCM_CONDVAR_DATA.
* coop-threads.c, coop-threads.h, coop.c, fsu-pthreads.h,
mit-pthreads.c, mit-pthreads.h, threads.c, threads.h: Replaced
"gscm" --> "scm" everywhere. Lots of name changes to concord with
new Guile.
Thu Apr 4 10:19:56 1996 Tom Tromey <tromey@creche.cygnus.com>
Fixed CFLAGS usage:
* Makefile.in (XCFLAGS): New macro.

* configure.in (CFLAGS): Use "test !=", not "! test".
Fri Mar 29 11:51:18 1996 Anthony Green <green@snuffle.cygnus.com>

Added dummy yield function.
Tue Mar 26 15:17:42 1996 Anthony Green (green@gerbil.cygnus.com)

among multiple cooperative threads. Replaces system call.

* coop.c (COOP_STKSIZE): Boosted default stack size.
