glib/gmodule/ChangeLog

2001-01-27  Tor Lillqvist  <tml@iki.fi>

	* gmodule.c: (Win32) Need <io.h> for open() and close().

2000-12-22  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* gmodule.c: Make g_module_open more tolerant wrt to the module
	name. First it tries to open the module as named, if that fails,
	it checks, whether it is a libtool archive and parses it, if that
	fails it appends the systems shared library suffix
	(i.e. ".so") (if not already found) and tries again and if that
	fails it tries to append the ".la" libtool suffix (if not already
	found) and parses it.

	* gmodule.c: Lock recursive mutex during most module functions for
	safety.

	* gmodule-dl.c: Return an error from _g_module_symbol only, if
	dlerror says so. All other functions return an error as well, if
	dlerror returns NULL.

	* testgmodule.c: Thanks to the above change the #ifdefs have
	vanished.

2000-10-15  Raja R Harinath  <harinath@cs.umn.edu>

	* Makefile.am (BUILT_EXTRA_DIST): New variable.
	(dist-hook): Handle $(BUILT_EXTRA_DIST).

2000-09-28  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* gmodule.h: Moved declaration of g_log_domain_gmodule up before
	the inclusion of glib.h to make it compile on non-gcc compilers.

2000-07-22  Tor Lillqvist  <tml@iki.fi>

	* makefile.mingw.in: Remove leftover gmodule-win32res.o stuff. The
	build-dll script automagically handles resources.

2000-07-20  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* libgplugin_a.c, testgmodule.c: Use g_path_get_basename instead
	of the deprecated g_basename.

2000-07-19  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* gmodule.h: include glib.h before doing extern "C". Makes some C++
	compiler happy. Reported by Denis Vakatov
	<vakatov@peony.nlm.nih.gov>.

2000-07-19  Tor Lillqvist  <tml@iki.fi>

	* gmodule-win32.c: Don't #include <tlhelp32.h> when compiling with
	gcc, as it isn't provided. Declaration of a needed struct (from
	www.microsoft.com) inserted instead.

2000-05-13  Tor Lillqvist  <tml@iki.fi>

	* makefile.mingw.in: New file, with gmodule stuff
	moved from ../makefile.mingw.in.

	* Makefile.am: Add to EXTRA_DIST, and add rule to make makefile.mingw.

2000-05-02  Tor Lillqvist  <tml@iki.fi>

	* gmodule-win32.c: No need to include <psapi.h>

2000-03-23  Tor Lillqvist  <tml@iki.fi>

	* gmodule-win32.c (_g_module_symbol): When looking for symbols in
	the "main" module we must search both the main program and all
	currently loaded DLLs. Not only the main program, or even just the
	DLLs loaded as gmodules.  Libglade requires this.

	Thus we need to get a list of all modules in the current
	process. There are two alternative APIs to do this: PSAPI and
	Toolhelp. The former is only available on NT (including Win2k),
	the latter on Win9x and Win2k. Check which one works, and use
	that.

	First check for the symbol in the main program, and if not found
	there, in all the modules.

	Code for using PSAPI and Toolhelp was borrowed from the Dr. Mingw
	tool written by Jos<6F> Fonseca <em96115@fe.up.pt>. Thanks.

2000-03-04  Tor Lillqvist  <tml@iki.fi>

	* gmodule-win32.c: Call g_win32_error_message() to get the error
	message strings.

	* libgplugin_a.c
	* libgplugin_b.c
	* gmodule.c: Remove LibMain functions that were needed by LCC,
	which is not a supported compiler.

	* testgmodule.c (main): Test for G_MODULE_IMPL ==
	G_MODULE_IMPL_WIN32, not G_OS_WIN32.

	* gmoduleconf.h.win32: Remove LCC stuff from here, too. 

Wed Mar  1 05:34:47 2000  Tim Janik  <timj@gtk.org>

	* gmodule-beos.c (_g_module_symbol): do not return NULL symbols.

	* gmodule-os2.c: removed NetBSD specific defines.
	(_g_module_self): set an error message for unsupported behaviour.

	* gmodule-beos.c: many coding style fixups.
	(_g_module_open):
	(_g_module_self):
	(_g_module_close):
	(_g_module_symbol): bunch of memory leaks plugged.

	* gmodule-dl.c: make sure the error message returned from dlerror()
	is always != NULL, by using a wrapper function fetch_dlerror(). based
	on a patch to fix _g_module_symbol() for NetBSD from Scott Presnell
	<srp@zgi.com>.

	* gmodule-dld.c: minor indentation.

	* gmodule-win32.c: minor cleanups.

	* merges from glib-1-2.

Sat Feb 19 19:43:29 2000  Tim Janik  <timj@gtk.org>

	* testgmodule.c (main): added test to check that not yet bound symbols
	in shared libraries of the main module are retrievable, from David Gero.

2000-01-13  Martin Baulig  <martin@home-of-linux.org>

	* gmodule.c (g_module_open): Check whether `check_init' is not NULL
	before we attempt to call it.

Sun Oct  3 19:30:52 PDT 1999 Manish Singh <yosh@gimp.org>

	* gmodule.h
	* testgmodule.c: use G_OS stuff

Sat Jul 24 20:47:18 1999  Tim Janik  <timj@gtk.org>

	* merged changes from GLib-1-2 branch.

1999-05-06  Tor Lillqvist  <tml@iki.fi>

	* gmodule.c: Remove LibMain.

Sat May  1 10:58:57 PDT 1999 Manish Singh <yosh@gimp.org>

	* Makefile.am: use -avoid-version and -module for test plugins

Mon Apr 19 08:43:59 1999  ape@lrdpf.spacetec.no  (Asbjorn Pettersen)

	* Makefile.am (EXTRA_DIST): Add gmodule-os2.c

Wed Apr  7 20:12:58 1999  ape@lrdpf.spacetec.no  (Asbjorn Pettersen)

	* gmodule-os2.c: OS/2 specific file for gmodule.
	* gmodule.c (_g_module_open): Add gmodule-os2.c if G_MODULE_IMPL_OS2.
	* gmoduleconf.h.in: Add G_MODULE_IMPL_OS2.

Fri Apr 23 09:03:48 1999  Tim Janik  <timj@gtk.org>

	* gmodule.c (g_module_symbol): removed inline variable assignment.
	s/CHECK_ERROR/SUPPORT_OR_RETURN/ to make the code more self descriptive.

Wed Feb 10 12:06:30 1999  Tim Janik  <timj@gtk.org>

	* gmodule.c (CHECK_ERROR): be more descriptive on unsupported systems.

Wed Feb 10 07:56:33 1999  Tim Janik  <timj@gtk.org>

	* gmodule.c (g_module_error): fixed errernerous code wrt to thread
	specific error string allocation handling.

Thu Jan 21 12:40:11 EST 1999  Jeff Garzik  <jgarzik@pobox.com>

	* gmodule-dl.c (_g_module_build_path):
	Add braces to eliminate an ambiguous else warning.

1999-01-16  Tor Lillqvist  <tml@iki.fi>

	* gmodule-dl.c gmodule-dld.c: In
 	_g_module_build_path, don't add the "lib" prefix and
 	".so" or ".sl" suffix if already there.

	* gmodule-win32.c: Likewise for the ".dll" suffix.

1998-12-10  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* gmodule.c: Made it MT safe, the g_module_error() is now thread
	specific.

Fri Nov 20 14:43:44 1998  Tim Janik  <timj@gtk.org>

	* gmodule.c (_g_module_build_path): added empty default imlementation
	so gmodule.so compiles on systems that are not yet supported, fix from
	Erik Bagfors <bagfors@hpc2n.umu.se>.

1998-11-13  Nuno Ferreira  <nmrf@rnl.ist.utl.pt>

	* Makefile.am (INCLUDES): The previous commit message is wrong
	about the -I$(top_srcdir) being redundant. I put it back.

Wed Nov 11 23:23:22 EST 1998 Jeff Garzik <jgarzik@pobox.com>

	* Makefile.am : INCLUDES is the right way to add to CFLAGS, not 
	DEFS.  Also there are bugs with '+=' in makefiles.
	Got rid of DEFS line by moving G_LOG_DOMAIN setting into INCLUDES.
	Removed redundant -I from INCLUDES.

Tue Oct 27 04:00:11 1998  Tim Janik  <timj@gtk.org>

	* testgmodule.c (main): changed the #ifdef WIN32 test to NATIVE_WIN32,
	this needs to be more constistent throughout the code, do we go for
	NATIVE_WIN32 or WIN32?

	* gmodule.c (LibMain): special cased the #ifdef __LCC__ case for
	NATIVE_WIN32, since lcc maybe used on other platforms as well.
	* libgplugin_a.c (LibMain): 
	* libgplugin_b.c (LibMain): 
	likewise. not sure i like this special requirement for lcc in here.

	* gmodule-dl.c (_g_module_build_path): 
	feature empty "" directories and prepend the module name with "lib".

	* gmodule-dld.c (_g_module_build_path): 
	* gmodule-win32.c (_g_module_build_path): 
	feature empty "" directories.

	* we need some more magic in the _g_module_build_path variants
	so we don't append/prepend lib and .so, .sl or .dll for those names
	that already contain it.

	* applied patch from Tor Lillqvist for g_module_build_path() and
	windows support.

1998-10-20: Tor Lillqvist <tml@iki.fi>

	* gmodule/gmodule-win32.c:
	New file.

	* gmodule/gmodule.c gmodule/gmodule.h:
	Added the funcion g_module_build_path that builds the path to
	a module file, decorating the name according to the system's
	conventions.  Added the Windows implementation.

	* gmodule/libgplugin_a.c gmodule/libgplugin_b.c:
	Added LibMain for LCC-Win32.

	* gmodule/testgmodule.c:
	Handle Windows dll names.

1998-10-25  Raja R Harinath  <harinath@cs.umn.edu>

	* gmodule.h: Remove `#pragma }'.
	* gmoduleconf.h.in: Likewise.

Wed Oct 21 19:58:27 1998  Tim Janik  <timj@gtk.org>

	* gmodule.c (g_module_symbol): fixed a string pointer bug that could
 	cause garbage error messages from g_module_symbol() for systems that
	NEED_USCORE.

Mon Sep 21 01:54:48 1998  Tim Janik  <timj@gtk.org>

	* gmodule.h: 
	* gmodule.c: renamed old _de_init functionality to _unload.
	modules are now expected to export:
	G_MODULE_EXPORT const gchar* g_module_check_init (GModule *module);
	and
	G_MODULE_EXPORT void g_module_unload (GModule *module);
	returning a string other than NULL from g_module_check_init() will
 	prevent the module from being loaded. a call to g_module_make_resident()
	from g_module_unload() will prevent the module from being unloaded and
	still make it resident.

Thu Sep 17 06:34:22 1998  Tim Janik  <timj@gtk.org>

	* gmodule.h: 
	* gmodule.c: implemented g_module_make_resident() which can be
	used to make modules resident.
	fixed a buglet about the optional "g_module_de_init" function in
	modules, which could get invoked twice on very obscure occasions.

Tue Sep 15 14:57:30 1998  Owen Taylor  <otaylor@redhat.com>

	* Makefile.am: Update to libtool-1.2b,
	change library versioning scheme to drop LT_RELEASE
	from the -l line, while keeping it in the soname.

Thu Aug 20 07:08:16 1998  Tim Janik  <timj@gtk.org>

	* gmodule.c: provide no operation implementation for the underlying
	_g_module_* functions, so we at least compile on systems that have
 	neither of G_MODULE_IMPL_DL or G_MODULE_IMPL_DLD.

Mon Aug 17 03:41:52 1998  Tim Janik  <timj@gtk.org>

	* gmodule.h:
	* gmodule.c (g_module_open): changed the return type for the
	GModuleCheckInit function to be a string, describing the error
	condition.
	(g_module_symbol): show the failing symbol on error messages.

Fri Aug 14 02:24:39 1998  Tim Janik  <timj@gtk.org>

	* Makefile.am: feature the G_LOG_DOMAIN macro to set the log domain
	to "GModule" upon compilation. we currently have to add this definition
	to the DEFS variable.
	* testgmodule.c: we need an ugly #undef G_LOG_DOMAIN at the start
	of this file currently, since automake doesn't support per target
	_CFLAGS yet.

Mon Aug 10 03:35:57 1998  Tim Janik  <timj@gtk.org>

	* gmodule.c: minor changes to internal interface.
	* gmodule-dl.c: 
	* gmodule-dld.c: put some comments into the files, and provided
	better error checking for shl_findsym(). whish i had a system to
 	test this stuff on.

Mon Aug 10 02:18:31 1998  Tim Janik  <timj@gtk.org>

	* Makefile.am (lib_LTLIBRARIES): for now, skip the dependency on
	-lglib for libgmodule-1.1.la, libgplugin_a.la and libgplugin_b.la
	since this clashes with inter-library-dependencies for not installed
	libraries. glib-config takes care of this for the usuall case, but
	there needs to be a better way...

Sun Aug  9 15:57:38 1998  Tim Janik  <timj@gtk.org>

	* testgmodule.c: test program for GModule.
	* libgplugin_a.c: 
	* libgplugin_b.c: test plugins for testgmodule.c.

	* gmodule.h: 
	* gmodule.c: GModule library implementation, which is basically
	a wrapper about system specifc dynamic loading facilities.

Sun Aug  9 10:31:05 1998  Tim Janik  <timj@gtk.org>

	* ChangeLog start for gmodule.
