* configure.in: Determine the suffix of the shared librarries for
this system. This is done analogous to
ltconfig.sh. G_MODULE_SUFFIX in glibconfig.h is set to either
"sl", "dll", or (most often) "so".
* tests/Makefile.am, tests/module-test.c,
tests/libmoduletestplugin_a.c, tests/libmoduletestplugin_b.c:
Added new testcase for gmodule. This is mostly copied from
gmodule/testgmodule.c, but unlike that is is quiet. (Why BTW are
some tests that verbose, not to say loquacious...)
* 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.
* glib/glib-sections.txt: Added G_MODULE_SUFFIX.
* glib/tmpl/modules.sgml: Updated.

removed dummy structure definitions for struct _GCache, _GTree, _GTimer,
Tue Oct 27 03:00:50 1998 Tim Janik <timj@gtk.org>
* glib.h: removed dummy structure definitions for struct _GCache,
_GTree, _GTimer, _GMemChunk, _GListAllocator and _GStringChunk.
* gutils.c: implement glib's inline functions _after_ all include
statements have been processed.
removed Tor's MAXPATHLEN check since there already was one supplied
further down in this file.
(LibMain): special cased the #ifdef __LCC__ case for NATIVE_WIN32,
since lcc maybe used on other platforms as well. why in hell is this
stuff required?
(g_get_any_init): for windows, if the user name is supplied, use it as
realname also.
in general, if there is no homedir specified, use the tmpdir that
we already figured.
* gtimer.c (g_timer_elapsed): changed a g_assert() statement to
g_return_if_fail().
* applied glib-tml-981020-0.patch for WIN32 portability, added some
comments and g_return_if_fail() statements, minor indentation fixes.

1998-10-20: Tor Lillqvist <tml@iki.fi>
* README.win32 glib.def gmodule.def
* glibconfig.h.win32 gmodule/gmoduleconf.h.win32:
New files for the Windows port. The .def files list exported
symbols for the Microsoft linker and compatibles.
* configure.in:
Added checks for some platform-dependent headers: pwd.h sys/param.h
sys/select.h sys/time.h sys/times.h unistd.h, and the function lstat.
* gerror.c:
Conditionalized inclusion of system-dependent headers. Changes
for Windows: no gdb to do a stack trace. Just call abort().
* glib.h:
Changes for Windows:
Added macros G_DIR_SEPARATOR, G_DIR_SEPARATOR_S for
platform-dependent file name syntax elements. Added macros
G_SEARCHPATH_SEPARATOR, G_SEARCHPATH_SEPARATOR_S for
platform-dependent search path syntax conventions.
Added pragmas for Microsoft C to make it more pedantic.
Marked GLib's global variables for export from DLL.
Added the function g_strescape that escapes backslashes.
Added functions g_path_is_absolute and g_path_skip_root to
handle platform-dependent file name syntax.
Added the function g_getenv that expands environment variables
that contain references to other environment variables, as is
typical on Windows NT.
Added the GIOChannel structure which is used to encapsulate the
IPC mechanism used by the GIMP's plug-ins, and possibly other
things later. On Unix a GIOChannel encapsulates just a file
descriptor. On Windows it contains a file handle from _pipe() and a
few other things related to the implementation of gdk_input_add
and GIMP plug-in communication. Subject to change.
Removed duplicate declarations of the version variables.
For the Microsoft compiler, declare own implementation of
ftruncate and the <dirent.h> functions.
* gmem.c:
Define a symbolic name for the profiling table size.
* gmessages.c:
Conditionalized inclusion of unistd.h. On Windows, output using
stdio to stdout.
* gscanner.c:
Conditionalized inclusion of unistd.h. Added changes for
Microsoft C. Added CR to the skipped character set. Added small
workaround for MSC compiler bug in g_scanner_cur_value.
* gstrfuncs.c:
Added the function g_strescape, which escapes the backslash
character. Needed especially when printing Windows filenames.
* gtimer.c:
Conditionalized inclusion of unistd.h and sys/time.h. Added
implementations for Windows.
* gutils.c:
Conditionalized inclusion of platform-dependent headers. Use
the platform-independent file name syntax macros.
Conditionalize code on platform-dependent features. Added the
functions g_path_is_absolute g_path_skip_root and g_getenv.
Added the GIOChannel-related functions. Added
compiler-dependent Unix compatibility functions for Windows.
* makefile.lcc makefile.msc:
New files. Compiler-specific makefiles for LCC-Win32 and
Microsoft C. Only Microsoft C is actually supported currently.
* testglib.c:
Added pathname check cases for Windows. Added workaround for
bug in the Microsoft runtime library. Improved some tests a bit.
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.

sys/select.h sys/time.h sys/times.h unistd.h, and the function lstat.
* gerror.c:
Conditionalized inclusion of system-dependent headers. Changes
for Windows: no gdb to do a stack trace. Just call abort().
* glib.h:
Changes for Windows:
Added macros G_DIR_SEPARATOR, G_DIR_SEPARATOR_S for
platform-dependent file name syntax elements. Added macros
G_SEARCHPATH_SEPARATOR, G_SEARCHPATH_SEPARATOR_S for
platform-dependent search path syntax conventions.
Added pragmas for Microsoft C to make it more pedantic.
Marked GLib's global variables for export from DLL.
Added the function g_strescape that escapes backslashes.
Added functions g_path_is_absolute and g_path_skip_root to
handle platform-dependent file name syntax.
Added the function g_getenv that expands environment variables
that contain references to other environment variables, as is
typical on Windows NT.
Added the GIOChannel structure which is used to encapsulate the
IPC mechanism used by the GIMP's plug-ins, and possibly other
things later. On Unix a GIOChannel encapsulates just a file
descriptor. On Windows it contains a file handle from _pipe() and a
few other things related to the implementation of gdk_input_add
and GIMP plug-in communication. Subject to change.
Removed duplicate declarations of the version variables.
For the Microsoft compiler, declare own implementation of
ftruncate and the <dirent.h> functions.
* gmem.c:
Define a symbolic name for the profiling table size.
* gmessages.c:
Conditionalized inclusion of unistd.h. On Windows, output using
stdio to stdout.
* gscanner.c:
Conditionalized inclusion of unistd.h. Added changes for
Microsoft C. Added CR to the skipped character set. Added small
workaround for MSC compiler bug in g_scanner_cur_value.
* gstrfuncs.c:
Added the function g_strescape, which escapes the backslash
character. Needed especially when printing Windows filenames.
* gtimer.c:
Conditionalized inclusion of unistd.h and sys/time.h. Added
implementations for Windows.
* gutils.c:
Conditionalized inclusion of platform-dependent headers. Use
the platform-independent file name syntax macros.
Conditionalize code on platform-dependent features. Added the
functions g_path_is_absolute g_path_skip_root and g_getenv.
Added the GIOChannel-related functions. Added
compiler-dependent Unix compatibility functions for Windows.
* makefile.lcc makefile.msc:
New files. Compiler-specific makefiles for LCC-Win32 and
Microsoft C. Only Microsoft C is actually supported currently.
* testglib.c:
Added pathname check cases for Windows. Added workaround for
bug in the Microsoft runtime library. Improved some tests a bit.
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.

Determine the suffix of the shared librarries for this system. This is
2000-12-22 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Determine the suffix of the shared librarries for
this system. This is done analogous to
ltconfig.sh. G_MODULE_SUFFIX in glibconfig.h is set to either
"sl", "dll", or (most often) "so".
* tests/Makefile.am, tests/module-test.c,
tests/libmoduletestplugin_a.c, tests/libmoduletestplugin_b.c:
Added new testcase for gmodule. This is mostly copied from
gmodule/testgmodule.c, but unlike that is is quiet. (Why BTW are
some tests that verbose, not to say loquacious...)
* 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.
* glib/glib-sections.txt: Added G_MODULE_SUFFIX.
* glib/tmpl/modules.sgml: Updated.

Changes for 64-bit cleanliness, loosely based on patch from Mark Murnane.
Wed Jun 20 12:00:54 2001 Owen Taylor <otaylor@redhat.com>
Changes for 64-bit cleanliness, loosely based on patch
from Mark Murnane.
* gconvert.c (g_convert/g_convert_with_fallback): Remove
workarounds for since-fixed GNU libc bugs. Minor
doc fix.
* gconvert.[ch]: Change gint to gsize/gssize as
appropriate.
* gconvert.c (g_locale/filename_to/from_utf8): Fix incorrect
computation of bytes_read / bytes_written.
* gfileutils.[ch] (g_file_get_contents): Make length
out parameter 'gsize *len'.
* ghook.c (g_hook_compare_ids): Don't compare a
and b as 'a - b'.
* gmacros.h (GSIZE_TO_POINTER): Add GPOINTER_TO_SIZE,
GSIZE_TO_POINTER.
* gmain.c (g_timeout_prepare): Rewrite to avoid
overflows. (Fixes bug when system clock skews
backwards more than 24 days.)
* gmarkup.[ch]: Make lengths passed to callbacks
gsize, length for g_markup_parse-context_parse(),
g_markup_escape_text() gssize.
* gmessages.[ch] (g_printf_string_upper_bound): Change
return value to gsize.
* gmessages.c (printf_string_upper_bound): Remove
a ridiculous use of 'inline' on a 300 line function.
* gstring.[ch]: Represent size of string as a gsize,
not gint. Make parameters to functions take gsize,
or gssize where -1 is allowed.
* gstring.c (g_string_erase): Make
g_string_erase (string, pos, -1) a synonym for
g_string_truncate for consistency with other G*
APIs.
* gstrfuncs.[ch]: Make all functions taking a string
length, take a gsize, or gssize if -1 is allowed.
(g_strstr_len, g_strrstr_len). Also fix some boundary
conditions in g_str[r]str[_len].
* gutf8.c tests/unicode-encoding.c: Make parameters that
are byte lengths gsize, gssize as appropriate. Make
character offsets, other counts, glong.
* gasyncqueue.c gcompletion.c
timeloop.c timeloop-basic.c gutils.c gspawn.c.
Small 64 bit cleanliness fixups.
* glist.c (g_list_sort2, g_list_sort_real): Fix functions
that should have been static.
* gdate.c (g_date_fill_parse_tokens): Fix extra
declaration that was shadowing another.
* tests/module-test.c: Include string.h
Mon Jun 18 15:43:29 2001 Owen Taylor <otaylor@redhat.com>
* gutf8.c (g_get_charset): Make argument
G_CONST_RETURN char **.

* configure.in: Determine the suffix of the shared librarries for

"sl", "dll", or (most often) "so".
* tests/Makefile.am, tests/module-test.c,

Added new testcase for gmodule. This is mostly copied from
gmodule/testgmodule.c, but unlike that is is quiet. (Why BTW are
some tests that verbose, not to say loquacious...)
* 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

* gmodule-dl.c: Return an error from _g_module_symbol only, if

version bump to 1.1.3, binary age 0, interface age 0.
Sun Aug 16 20:28:27 1998 Tim Janik <timj@gtk.org>
* version bump to 1.1.3, binary age 0, interface age 0.
* glib.h: be nice to platforms that don't have gint64 and don't
issue #warning on every compilation. since glib doesn't require
gint64 itself, packages that need gint64 should test for this
themselves.
* glib.h:
* gutils.c: added a new function g_vsnprintf().
Fri Aug 14 16:41:53 1998 Tim Janik <timj@gtk.org>
* glib.h: added static inline functions for bit mask tests:
g_bit_nth_lsf, g_bit_nth_msf and g_bit_storage.
Fri Aug 13 14:23:37 1998 Tim Janik <timj@gtk.org>
* glib.h:
* gmessages.c:
revised the message handling system, which is now based on a new
mechanism g_log*. most of the assertment macros got adapted to
feature the new g_log() call with an additional specification of
the log level in a preprocessor macro G_LOG_DOMAIN. if G_LOG_DOMAIN
is undefined upon the includion of glib.h, it'll be defined with a
value of (NULL) and thus preserves the original bahaviour for
warning and error messages. the message handler setting functions
for g_warning, g_error and g_message are only provided for backwards
compatibility and might get removed somewhen.
* Makefile.am: feature the G_LOG_DOMAIN macro to set the log domain
to "GLib" upon compilation. we currently have to add this definition
to the DEFS variable.
* testglib.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.
* glib.h: changed some gints to gbooleans, made a few const corrections,
removed some superfluous G_STMT_START{}G_STMT_END wrappers, added some
in other required places.
* gnode.c:
(g_node_prepend):
(g_node_insert_before):
(g_node_insert):
(g_node_append_data):
(g_node_prepend_data):
(g_node_insert_data_before):
(g_node_insert_data):
(g_node_append):
return (node), so these macros/functions can be usefully chained with
g_node_new().

removed dummy structure definitions for struct _GCache, _GTree, _GTimer,
Tue Oct 27 03:00:50 1998 Tim Janik <timj@gtk.org>
* glib.h: removed dummy structure definitions for struct _GCache,
_GTree, _GTimer, _GMemChunk, _GListAllocator and _GStringChunk.
* gutils.c: implement glib's inline functions _after_ all include
statements have been processed.
removed Tor's MAXPATHLEN check since there already was one supplied
further down in this file.
(LibMain): special cased the #ifdef __LCC__ case for NATIVE_WIN32,
since lcc maybe used on other platforms as well. why in hell is this
stuff required?
(g_get_any_init): for windows, if the user name is supplied, use it as
realname also.
in general, if there is no homedir specified, use the tmpdir that
we already figured.
* gtimer.c (g_timer_elapsed): changed a g_assert() statement to
g_return_if_fail().
* applied glib-tml-981020-0.patch for WIN32 portability, added some
comments and g_return_if_fail() statements, minor indentation fixes.
ChangeLog entry from Tor Lillqvist is appended.
* glib.h (struct dirent): use lower case structure members.
* glib.h:
* makefile.lcc:
* makefile.msc:
s/COMPILING_GLIB/GLIB_COMPILATION/
1998-10-20: Tor Lillqvist <tml@iki.fi>
* README.win32 glib.def gmodule.def
* glibconfig.h.win32 gmodule/gmoduleconf.h.win32:
New files for the Windows port. The .def files list exported
symbols for the Microsoft linker and compatibles.
* configure.in:
Added checks for some platform-dependent headers: pwd.h sys/param.h
sys/select.h sys/time.h sys/times.h unistd.h, and the function lstat.
* gerror.c:
Conditionalized inclusion of system-dependent headers. Changes
for Windows: no gdb to do a stack trace. Just call abort().
* glib.h:
Changes for Windows:
Added macros G_DIR_SEPARATOR, G_DIR_SEPARATOR_S for
platform-dependent file name syntax elements. Added macros
G_SEARCHPATH_SEPARATOR, G_SEARCHPATH_SEPARATOR_S for
platform-dependent search path syntax conventions.
Added pragmas for Microsoft C to make it more pedantic.
Marked GLib's global variables for export from DLL.
Added the function g_strescape that escapes backslashes.
Added functions g_path_is_absolute and g_path_skip_root to
handle platform-dependent file name syntax.
Added the function g_getenv that expands environment variables
that contain references to other environment variables, as is
typical on Windows NT.
Added the GIOChannel structure which is used to encapsulate the
IPC mechanism used by the GIMP's plug-ins, and possibly other
things later. On Unix a GIOChannel encapsulates just a file
descriptor. On Windows it contains a file handle from _pipe() and a
few other things related to the implementation of gdk_input_add
and GIMP plug-in communication. Subject to change.
Removed duplicate declarations of the version variables.
For the Microsoft compiler, declare own implementation of
ftruncate and the <dirent.h> functions.
* gmem.c:
Define a symbolic name for the profiling table size.
* gmessages.c:
Conditionalized inclusion of unistd.h. On Windows, output using
stdio to stdout.
* gscanner.c:
Conditionalized inclusion of unistd.h. Added changes for
Microsoft C. Added CR to the skipped character set. Added small
workaround for MSC compiler bug in g_scanner_cur_value.
* gstrfuncs.c:
Added the function g_strescape, which escapes the backslash
character. Needed especially when printing Windows filenames.
* gtimer.c:
Conditionalized inclusion of unistd.h and sys/time.h. Added
implementations for Windows.
* gutils.c:
Conditionalized inclusion of platform-dependent headers. Use
the platform-independent file name syntax macros.
Conditionalize code on platform-dependent features. Added the
functions g_path_is_absolute g_path_skip_root and g_getenv.
Added the GIOChannel-related functions. Added
compiler-dependent Unix compatibility functions for Windows.
* makefile.lcc makefile.msc:
New files. Compiler-specific makefiles for LCC-Win32 and
Microsoft C. Only Microsoft C is actually supported currently.
* testglib.c:
Added pathname check cases for Windows. Added workaround for
bug in the Microsoft runtime library. Improved some tests a bit.
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.
