1 2005-07-21 Matthias Clasen <mclasen@redhat.com>
3 * === Released 2.7.4 ===
5 2005-07-15 Matthias Clasen <mclasen@redhat.com>
7 * === Released 2.7.3 ===
9 2005-07-09 Tor Lillqvist <tml@novell.com>
11 * Makefile.am: Don't use the scripts in build/win32 to compile
12 gmodule.rc into a resource object file. (This means we lose the
13 build number increment magic, but I doubt it was that useful
14 anyway.) Instead use windres directly. To pass the normal .o file
15 produced by windres through libtool, which wants .lo files, pass
16 it directly to the linker using a -Wl option.
18 * gmodule.rc.in: Thus replace BUILDNUMBER with 0.
20 2005-07-08 Matthias Clasen <mclasen@redhat.com>
22 * === Released 2.7.2 ===
24 2005-06-30 Matthias Clasen <mclasen@redhat.com>
26 * === Released 2.7.1 ===
28 2005-06-30 Matthias Clasen <mclasen@redhat.com>
30 * gmodule-ar.c: Include stdlib.h
32 2005-06-26 Tor Lillqvist <tml@novell.com>
34 * Makefile.am: libtool installs/uninstalls the import library, no
35 need to do it ourselves. Do still install/uninstall the .def file,
38 2005-06-24 Tor Lillqvist <tml@novell.com>
40 * Makefile.am (install-libtool-import-lib): Current GNU tools do
41 understand the PRIVATE keyword.
43 2005-06-10 Matthias Clasen <mclasen@redhat.com>
45 * === Released 2.7.0 ===
47 2005-01-07 Matthias Clasen <mclasen@redhat.com>
49 * === Released 2.6.1 ===
51 2004-12-31 Tor Lillqvist <tml@iki.fi>
53 * gmodule.c (g_module_open): It's wrong to call g_file_test() with
54 more than one test (both G_FILE_TEST_EXISTS and _IS_REGULAR). (It
55 would succeed even if the pathname existed as a nonregular file.)
56 Just G_FILE_TEST_IS_REGULAR works fine. (#162594)
58 2004-12-16 Matthias Clasen <mclasen@redhat.com>
60 * === Released 2.6.0 ===
62 2004-12-06 Tor Lillqvist <tml@iki.fi>
66 * gmodule.[hc]: Win32 DLL ABI stability cruft like in ../glib.

72 2004-11-12 Matthias Clasen <mclasen@redhat.com>
74 * === Released 2.5.6 ===
76 2004-11-04 Tor Lillqvist <tml@iki.fi>
78 * gmodule-win32.c (_g_module_open): Argument is in UTF-8. Use wide
79 character Win32 API if present.
81 * gmodule.c (parse_libtool_archive, g_module_open): Convert file
82 name to UTF-8 before storing in the error message string.
84 * gmodule.c (parse_libtool_archive): Use g_open().

114 Tue May 11 23:23:21 2004 Matthias Clasen <maclas@gmx.de>
116 * gmodule-ar.c (_g_module_open): Make it compile on AIX.
117 (#141159, Michael Wilson)
119 2004-03-31 Tor Lillqvist <tml@iki.fi>
121 * gmodule-win32.c (_g_module_build_path): On Cygwin, use the "cyg"
122 prefix, and accept also the normal "lib". (#138403, Roger Leigh)
124 Tue Feb 24 14:09:21 2004 Owen Taylor <otaylor@redhat.com>
126 * === Released 2.3.3 ===
128 Sun Feb 22 02:28:43 2004 Matthias Clasen <maclas@gmx.de>
130 Bug #85930, Laurent Vivier:
132 * gmodule-ar.c: Implementation of native module management for AIX.
134 * gmodule.c: Support gmodule-ar.c
136 2003-01-01 Tor Lillqvist <tml@iki.fi>
138 * gmodule-win32.c (_g_module_build_path): Use g_ascii_strcasecmp().
140 Tue Dec 3 20:56:19 2002 Owen Taylor <otaylor@redhat.com>
142 * gmodule.c (g_module_open): Properly refcount the
143 main module if it is already open. (#98648)
145 Sat Mar 2 14:46:17 2002 Owen Taylor <otaylor@redhat.com>
147 * gmodule-beos.c (_g_module_build_path) * gmodule-dyld.c (_g_module_build_path)
148 gmodule-dl.c (_g_module_build_path): Use G_MODULE_SUFFIX rather than
149 a hardcoded ".so". (#72803)
151 Sun Feb 17 18:15:22 2002 Owen Taylor <otaylor@redhat.com>
153 * gmodule.c (g_module_open): Fix typo when checking
154 if file + module_suffix exists. (Miroslaw Dobrzanski-Neumann,
157 2001-11-24 Tor Lillqvist <tml@iki.fi>
159 * Makefile.am: Remove rule for testgmodule.exp, too.
161 2001-11-22 Tor Lillqvist <tml@iki.fi>
163 * gmodule-win32.c: Current w32api headers do include tlhelp32.h,
164 so no need to have an extract from it here.
166 Mon Nov 19 16:12:12 2001 Owen Taylor <otaylor@redhat.com>
168 * Makefile.am makefile.msc.in makefile.mingw.in: Remove
169 testgmodule and associated plugin files; we don't need _both_ this
170 and ../tests/module-test.c
172 2001-11-16 Michael Meeks <michael@ximian.com>
174 * gmodule.c (parse_libtool_archive): fix leak.
176 2001-10-30 Dan Winship <danw@ximian.com>
178 * Makefile.am (EXTRA_DIST): Add gmodule-dyld.c
180 2001-10-23 Tor Lillqvist <tml@iki.fi>
182 * Makefile.am: (Win32): If we have built the MSVC import library,
183 install it. Install the gcc import library. Also support
186 2001-10-09 Tor Lillqvist <tml@iki.fi>
188 * gmodule-win32.c (_g_module_build_path): More Unix compatibility:
189 Add "lib" prefix in case the module name doesn't already have it,
190 except if it ends with ".dll" (in which case it probably already
191 is the name of an existing DLL). This is needed for instance for
192 the gdk-pixbuf loaders, which are called "lib*.dll", but
193 gdk-pixbuf-io calls g_module_build_path without the "lib" prefix.
195 2001-10-03 jacob berkman <jacob@ximian.com>
197 * libgplugin_a.c: (gplugin_a_module_func):
198 * gmodule.h: s/retrive/retrieve/
200 2001-09-25 Tor Lillqvist <tml@iki.fi>
202 * makefile.mingw.in: Fix missing end @ in @LT_CURRENT@.
204 * makefile.msc.in: Use same DLL and import library names as
207 2001-09-19 Tor Lillqvist <tml@iki.fi>
209 * gmodule.rc.in: Correct InternalName and OriginalFilename to
210 match what we actually produce.
212 2001-09-18 Tor Lillqvist <tml@iki.fi>
214 * Makefile.am: On Win32, pass a dummy -rpath flag to libtool when
215 building libgplugin_[ab].la, otherwise libtool doesn't create a
216 DLL, but a static archive.
218 2001-07-20 Hans Breuer <hans@breuer.org>
220 * makefile.msc.in : reflect glib move
222 2001-05-21 Mark Murnane <Mark.Murnane@ireland.sun.com>
224 * gmodule.c (g_str_check_suffix): Modified type of string_len
225 and suffix_len to be gsize. Properly accommodates return from
228 2001-05-29 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
230 * gmodule.c (g_module_set_error_unduped): Do not g_strdup, as
231 promised in the function name.
233 Tue May 29 12:57:51 2001 Tim Janik <timj@gtk.org>
235 * gmodule.c (g_module_symbol): erk, strconcat needs NULL as last arg.
236 make sure we pass module name with suffix into backend open.
238 Mon May 28 20:19:25 2001 Tim Janik <timj@gtk.org>
240 * gmodule.c (g_module_open): as a last resort, if we can't access()
241 the module, leave it up to the platform backends to find it.
242 (fixes implicit search patch loading i broke with my last
243 commit, spotted by Padraig O'Briain).
245 Thu May 24 03:43:12 2001 Tim Janik <timj@gtk.org>
247 * gmodule.c (g_module_open): reordered code so we have a single
248 module loading point (for reliable error messages). do access()
249 tests to figure plausible file names.
250 make error messages more verbose so users canfigure what's going on.
252 2001-04-20 Dan Winship <danw@ximian.com>
254 * gmodule-dyld.c: gmodule implementation for Darwin/Mac OS X
257 * gmoduleconf.h.in: Add gmodule-dyld support
259 * testgmodule.c (main): Fix spelling
261 2001-03-13 Tor Lillqvist <tml@iki.fi>
263 From Edward M. Lee <tailbert@yahoo.com>:
265 * gmodule-win32.c (_g_module_build_path): use (cygwin friendly) dir
268 2001-03-12 Tor Lillqvist <tml@iki.fi>
270 * Makefile.am (libgplugin_a_la_LIBADD, libgplugin_b_la_LIBADD):
271 Link with the libgmodule la only on Win32.
273 2001-03-10 Tor Lillqvist <tml@iki.fi>
275 * Makefile.am: Use the _LIBADD dependency on libglib only on the
276 Win32 platform (including Cygwin).
278 2001-03-07 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
280 * Makefile.am, makefile.mingw.in, makefile.msc.in: Set
281 G_LOG_DOMAIN to \"GModule\" instead of g_log_domain_gmodule.
283 * gmodule.def, gmodule.h, gmodule.c: Removed g_log_domain_gmodule.
285 2001-02-21 Tor Lillqvist <tml@iki.fi>
287 * gmodule.h: Use G_BEGIN_DECLS and G_END_DECLS. Define
288 G_MODULE_EXPORT correctly on Cygwin, too.
290 * gmodule-win32.c (_g_module_open): Convert path to Windows format
293 * Makefile.am (libglib): Use libglib-1.3.la from
294 top_builddir. Invoke libtool with -no-undefined for Win32 and
297 2001-02-17 Havoc Pennington <hp@pobox.com>
299 Applied patch from Soeren Sandmann:
301 * gmodule.c (g_module_error): G_CONST_RETURN
302 (g_module_name): G_CONST_RETURN
304 Sat Feb 17 07:27:15 2001 Tim Janik <timj@gtk.org>
306 * gmodule.c: work around platforms that have broken RTLD_GLOBAL.
308 2001-01-27 Tor Lillqvist <tml@iki.fi>
310 * gmodule.c: (Win32) Need <io.h> for open() and close().
312 2000-12-22 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
314 * gmodule.c: Make g_module_open more tolerant wrt to the module
315 name. First it tries to open the module as named, if that fails,
316 it checks, whether it is a libtool archive and parses it, if that
317 fails it appends the systems shared library suffix
318 (i.e. ".so") (if not already found) and tries again and if that
319 fails it tries to append the ".la" libtool suffix (if not already
320 found) and parses it.
322 * gmodule.c: Lock recursive mutex during most module functions for
325 * gmodule-dl.c: Return an error from _g_module_symbol only, if
326 dlerror says so. All other functions return an error as well, if
327 dlerror returns NULL.
329 * testgmodule.c: Thanks to the above change the #ifdefs have
332 2000-10-15 Raja R Harinath <harinath@cs.umn.edu>
334 * Makefile.am (BUILT_EXTRA_DIST): New variable.
335 (dist-hook): Handle $(BUILT_EXTRA_DIST).
337 2000-09-28 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
339 * gmodule.h: Moved declaration of g_log_domain_gmodule up before
340 the inclusion of glib.h to make it compile on non-gcc compilers.
342 2000-07-22 Tor Lillqvist <tml@iki.fi>
344 * makefile.mingw.in: Remove leftover gmodule-win32res.o stuff. The
345 build-dll script automagically handles resources.
347 2000-07-20 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
349 * libgplugin_a.c, testgmodule.c: Use g_path_get_basename instead
350 of the deprecated g_basename.
352 2000-07-19 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
354 * gmodule.h: include glib.h before doing extern "C". Makes some C++
355 compiler happy. Reported by Denis Vakatov
356 <vakatov@peony.nlm.nih.gov>.
358 2000-07-19 Tor Lillqvist <tml@iki.fi>
360 * gmodule-win32.c: Don't #include <tlhelp32.h> when compiling with
361 gcc, as it isn't provided. Declaration of a needed struct (from
362 www.microsoft.com) inserted instead.
364 2000-05-13 Tor Lillqvist <tml@iki.fi>
366 * makefile.mingw.in: New file, with gmodule stuff
367 moved from ../makefile.mingw.in.
369 * Makefile.am: Add to EXTRA_DIST, and add rule to make makefile.mingw.
371 2000-05-02 Tor Lillqvist <tml@iki.fi>
373 * gmodule-win32.c: No need to include <psapi.h>
375 2000-03-23 Tor Lillqvist <tml@iki.fi>
377 * gmodule-win32.c (_g_module_symbol): When looking for symbols in
378 the "main" module we must search both the main program and all
379 currently loaded DLLs. Not only the main program, or even just the
380 DLLs loaded as gmodules. Libglade requires this.
382 Thus we need to get a list of all modules in the current
383 process. There are two alternative APIs to do this: PSAPI and
384 Toolhelp. The former is only available on NT (including Win2k),
385 the latter on Win9x and Win2k. Check which one works, and use
388 First check for the symbol in the main program, and if not found
389 there, in all the modules.
391 Code for using PSAPI and Toolhelp was borrowed from the Dr. Mingw
392 tool written by José Fonseca <em96115@fe.up.pt>. Thanks.
394 2000-03-04 Tor Lillqvist <tml@iki.fi>
396 * gmodule-win32.c: Call g_win32_error_message() to get the error
401 * gmodule.c: Remove LibMain functions that were needed by LCC,
402 which is not a supported compiler.
404 * testgmodule.c (main): Test for G_MODULE_IMPL ==
405 G_MODULE_IMPL_WIN32, not G_OS_WIN32.
407 * gmoduleconf.h.win32: Remove LCC stuff from here, too.
409 Wed Mar 1 05:34:47 2000 Tim Janik <timj@gtk.org>
411 * gmodule-beos.c (_g_module_symbol): do not return NULL symbols.
413 * gmodule-os2.c: removed NetBSD specific defines.
414 (_g_module_self): set an error message for unsupported behaviour.
416 * gmodule-beos.c: many coding style fixups.
420 (_g_module_symbol): bunch of memory leaks plugged.
422 * gmodule-dl.c: make sure the error message returned from dlerror()
423 is always != NULL, by using a wrapper function fetch_dlerror(). based
424 on a patch to fix _g_module_symbol() for NetBSD from Scott Presnell
427 * gmodule-dld.c: minor indentation.
429 * gmodule-win32.c: minor cleanups.
431 * merges from glib-1-2.
433 Sat Feb 19 19:43:29 2000 Tim Janik <timj@gtk.org>
435 * testgmodule.c (main): added test to check that not yet bound symbols
436 in shared libraries of the main module are retrievable, from David Gero.
438 2000-01-13 Martin Baulig <martin@home-of-linux.org>
440 * gmodule.c (g_module_open): Check whether `check_init' is not NULL
441 before we attempt to call it.
443 Sun Oct 3 19:30:52 PDT 1999 Manish Singh <yosh@gimp.org>
446 * testgmodule.c: use G_OS stuff
448 Sat Jul 24 20:47:18 1999 Tim Janik <timj@gtk.org>
450 * merged changes from GLib-1-2 branch.
452 1999-05-06 Tor Lillqvist <tml@iki.fi>
454 * gmodule.c: Remove LibMain.
456 Sat May 1 10:58:57 PDT 1999 Manish Singh <yosh@gimp.org>
458 * Makefile.am: use -avoid-version and -module for test plugins
460 Mon Apr 19 08:43:59 1999 ape@lrdpf.spacetec.no (Asbjorn Pettersen)
462 * Makefile.am (EXTRA_DIST): Add gmodule-os2.c
464 Wed Apr 7 20:12:58 1999 ape@lrdpf.spacetec.no (Asbjorn Pettersen)
466 * gmodule-os2.c: OS/2 specific file for gmodule.
467 * gmodule.c (_g_module_open): Add gmodule-os2.c if G_MODULE_IMPL_OS2.
468 * gmoduleconf.h.in: Add G_MODULE_IMPL_OS2.
470 Fri Apr 23 09:03:48 1999 Tim Janik <timj@gtk.org>
472 * gmodule.c (g_module_symbol): removed inline variable assignment.
473 s/CHECK_ERROR/SUPPORT_OR_RETURN/ to make the code more self descriptive.
475 Wed Feb 10 12:06:30 1999 Tim Janik <timj@gtk.org>
477 * gmodule.c (CHECK_ERROR): be more descriptive on unsupported systems.
479 Wed Feb 10 07:56:33 1999 Tim Janik <timj@gtk.org>
481 * gmodule.c (g_module_error): fixed errernerous code wrt to thread
482 specific error string allocation handling.
484 Thu Jan 21 12:40:11 EST 1999 Jeff Garzik <jgarzik@pobox.com>
486 * gmodule-dl.c (_g_module_build_path):
487 Add braces to eliminate an ambiguous else warning.
489 1999-01-16 Tor Lillqvist <tml@iki.fi>
491 * gmodule-dl.c gmodule-dld.c: In
492 _g_module_build_path, don't add the "lib" prefix and
493 ".so" or ".sl" suffix if already there.
495 * gmodule-win32.c: Likewise for the ".dll" suffix.
497 1998-12-10 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
499 * gmodule.c: Made it MT safe, the g_module_error() is now thread
502 Fri Nov 20 14:43:44 1998 Tim Janik <timj@gtk.org>
504 * gmodule.c (_g_module_build_path): added empty default imlementation
505 so gmodule.so compiles on systems that are not yet supported, fix from
506 Erik Bagfors <bagfors@hpc2n.umu.se>.
508 1998-11-13 Nuno Ferreira <nmrf@rnl.ist.utl.pt>
510 * Makefile.am (INCLUDES): The previous commit message is wrong
511 about the -I$(top_srcdir) being redundant. I put it back.
513 Wed Nov 11 23:23:22 EST 1998 Jeff Garzik <jgarzik@pobox.com>
515 * Makefile.am : INCLUDES is the right way to add to CFLAGS, not
516 DEFS. Also there are bugs with '+=' in makefiles.
517 Got rid of DEFS line by moving G_LOG_DOMAIN setting into INCLUDES.
518 Removed redundant -I from INCLUDES.
520 Tue Oct 27 04:00:11 1998 Tim Janik <timj@gtk.org>
522 * testgmodule.c (main): changed the #ifdef WIN32 test to NATIVE_WIN32,
523 this needs to be more constistent throughout the code, do we go for
524 NATIVE_WIN32 or WIN32?
526 * gmodule.c (LibMain): special cased the #ifdef __LCC__ case for
527 NATIVE_WIN32, since lcc maybe used on other platforms as well.
528 * libgplugin_a.c (LibMain):
529 * libgplugin_b.c (LibMain):
530 likewise. not sure i like this special requirement for lcc in here.
532 * gmodule-dl.c (_g_module_build_path):
533 feature empty "" directories and prepend the module name with "lib".
535 * gmodule-dld.c (_g_module_build_path):
536 * gmodule-win32.c (_g_module_build_path):
537 feature empty "" directories.
539 * we need some more magic in the _g_module_build_path variants
540 so we don't append/prepend lib and .so, .sl or .dll for those names
541 that already contain it.
543 * applied patch from Tor Lillqvist for g_module_build_path() and
546 1998-10-20: Tor Lillqvist <tml@iki.fi>
548 * gmodule/gmodule-win32.c:
551 * gmodule/gmodule.c gmodule/gmodule.h:
552 Added the funcion g_module_build_path that builds the path to
553 a module file, decorating the name according to the system's
554 conventions. Added the Windows implementation.
556 * gmodule/libgplugin_a.c gmodule/libgplugin_b.c:
557 Added LibMain for LCC-Win32.
559 * gmodule/testgmodule.c:
560 Handle Windows dll names.
562 1998-10-25 Raja R Harinath <harinath@cs.umn.edu>
564 * gmodule.h: Remove `#pragma }'.
565 * gmoduleconf.h.in: Likewise.
567 Wed Oct 21 19:58:27 1998 Tim Janik <timj@gtk.org>
569 * gmodule.c (g_module_symbol): fixed a string pointer bug that could
570 cause garbage error messages from g_module_symbol() for systems that
573 Mon Sep 21 01:54:48 1998 Tim Janik <timj@gtk.org>
576 * gmodule.c: renamed old _de_init functionality to _unload.
577 modules are now expected to export:
578 G_MODULE_EXPORT const gchar* g_module_check_init (GModule *module);
580 G_MODULE_EXPORT void g_module_unload (GModule *module);
581 returning a string other than NULL from g_module_check_init() will
582 prevent the module from being loaded. a call to g_module_make_resident()
583 from g_module_unload() will prevent the module from being unloaded and
584 still make it resident.

589 * gmodule.c: implemented g_module_make_resident() which can be
590 used to make modules resident.
591 fixed a buglet about the optional "g_module_de_init" function in
592 modules, which could get invoked twice on very obscure occasions.
594 Tue Sep 15 14:57:30 1998 Owen Taylor <otaylor@redhat.com>
596 * Makefile.am: Update to libtool-1.2b,
597 change library versioning scheme to drop LT_RELEASE
598 from the -l line, while keeping it in the soname.
600 Thu Aug 20 07:08:16 1998 Tim Janik <timj@gtk.org>
602 * gmodule.c: provide no operation implementation for the underlying
603 _g_module_* functions, so we at least compile on systems that have
604 neither of G_MODULE_IMPL_DL or G_MODULE_IMPL_DLD.
606 Mon Aug 17 03:41:52 1998 Tim Janik <timj@gtk.org>
609 * gmodule.c (g_module_open): changed the return type for the
610 GModuleCheckInit function to be a string, describing the error
612 (g_module_symbol): show the failing symbol on error messages.
614 Fri Aug 14 02:24:39 1998 Tim Janik <timj@gtk.org>
616 * Makefile.am: feature the G_LOG_DOMAIN macro to set the log domain
617 to "GModule" upon compilation. we currently have to add this definition
618 to the DEFS variable.
619 * testgmodule.c: we need an ugly #undef G_LOG_DOMAIN at the start
620 of this file currently, since automake doesn't support per target
623 Mon Aug 10 03:35:57 1998 Tim Janik <timj@gtk.org>
625 * gmodule.c: minor changes to internal interface.
627 * gmodule-dld.c: put some comments into the files, and provided
628 better error checking for shl_findsym(). whish i had a system to
631 Mon Aug 10 02:18:31 1998 Tim Janik <timj@gtk.org>
633 * Makefile.am (lib_LTLIBRARIES): for now, skip the dependency on
634 -lglib for libgmodule-1.1.la, libgplugin_a.la and libgplugin_b.la
635 since this clashes with inter-library-dependencies for not installed
636 libraries. glib-config takes care of this for the usuall case, but
637 there needs to be a better way...
639 Sun Aug 9 15:57:38 1998 Tim Janik <timj@gtk.org>
641 * testgmodule.c: test program for GModule.
643 * libgplugin_b.c: test plugins for testgmodule.c.
646 * gmodule.c: GModule library implementation, which is basically
647 a wrapper about system specifc dynamic loading facilities.

651 * ChangeLog start for gmodule.
