Some of the thread support code (threads.c, coop.c, etc.) used to live
2
in a separate directory called threads. In April 1997, that dir was
3
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
11
Fri Feb 21 23:52:16 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
13
* Makefile.am (modincludedir, modinclude_HEADERS): Added until
14
libthreads is integrated into libguile, otherwise people who try
15
to use Guile from an independent application will have trouble
16
finding libguile/../threads/threads.h.
18
Sat Jan 11 18:35:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
20
* Makefile.am (noinst_HEADERS): Added coop-defs.h so that it gets

Tue Jan 7 14:05:35 1997 Mikael Djurfeldt <mdj@kenneth>
25
* coop-defs.h: Added includes which define `time_t'.
27
Sun Jan 5 15:07:07 1997 Jim Blandy <jimb@floss.cyclic.com>
29
* Makefile.am (EXTRA_DIST): Add .cvsignore.
31
* Makefile.am (libthreads_a_SOURCES): Add threads.h. I think this
33
(noinst_HEADERS): Remove it from here.
34
* Makefile.in: Rebuilt.

Thu Jan 2 15:15:16 1997 Mikael Djurfeldt <mdj@kenneth>
38
These changes separates threads declarations which everybody wants
39
to see (coop-defs.h) from declarations internal to the threads
40
module (coop-threads.h), thereby solving the "-I ../qt" problem.
41
(This is not the final solution. All files in the threads
42
directory should be moved into libguile since 1. it is too tightly
43
interconnected with libguile internals to be a separate module and
44
2. it is actually quite small. When doing this, things can be
45
organized in a more natural way.)
47
* coop-defs.h: New file.
49
* coop-threads.c: Added #include "coop-threads.h"
51
* 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

69
Sun Nov 10 18:21:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
71

74
Sun Nov 10 17:41:21 1996 Jim Blandy <jimb@floss.cyclic.com>
76
* Makefile.in, configure.in: When threads are disabled,
77
short-circuit the `install' and `uninstall' Makefile targets too.
79
Sat Nov 2 21:29:33 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
81
* threads.c: Added #include "dynwind.h".
82

84
* mit-pthreads.c, mit-pthreads.h: Port completed but untested.

* Makefile.in (source, h_files, ancillary): Updated to describe
111
the actual contents of the tree.
112
(PLUGIN_distfiles): New variable.
113
(dist-dir): New target, to create a sub-tree of a distribution.
115
* Makefile.in (all): Depend on @target_all@ instead of
116
libthreads.a, so the configure script can make this makefile do
117
nothing when threads aren't in use.
118
* configure.in: If we using cooperative threads, then let
119
@target_all@ expand to libthreads.a; otherwise, let it expand to

147
* coop-threads.c (scm_threads_mark_stacks): scm_save_regs_gc_mark

is already in root state (should it really?). Don't allocate it
149
locally; Remove extra argument to scm_mark_locations.
151
* coop-threads.h: Changed #include <qt.h> --> #include "../qt/qt.h"
152

168
(launch_thread): thunk and handler is passed as a scheme list.
169
Call scm_with_new_root instead of scm_with_dynamic_root. Let

scm_with_new_root care about thread local variables. Removed
171
