NEWS file update for upcoming release of GLib + GModule version 1.1.3,

Browse Source 
Mon Sep 21 02:22:12 1998  Tim Janik  <timj@gtk.org>

        * NEWS file update for upcoming release of GLib + GModule
        version 1.1.3, binary age 0, interface age 0. (GModule uses
        the same version numbers as GLib.)

        * glib.h: swap the inclusion of of float.h and limits.h to work
        around a egcs 1.1 oddity on Solaris 2.5.1 (fix provided by
        Per Abrahamsen  <abraham@dina.kvl.dk>).

        * glib.h:
        * gscanner.c: renamed the GValue union to GTokenValue, this should
        not affect source compatibility in most cases.

        * ghash.c: added some g_return_if_fail() statements. make
        g_hash_table_lookup_node() an inline function so we save an extra
        function invokation on lookups.

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.

Overview of Changes in GLib 1.1.3:
* New library gmodule included which basically wraps dlopen() facilities.
* New GModule mechanism (implemented in an extra library) which wraps dynamic
object code loading facilities in a portable manner.
* glib-config features extra "glib" (old behaviour remains) and "gmodule"
(add libgmodule.so to the --libs output) arguments now. this can also
be specified as fourth argument to the AM_PATH_GLIB() macro.
* Overhaul of the `inline' autoconfiguration stuff, so inlining should be
sufficiently supported on all systems that allow inlining now.
* New g_log() mechanism for logging of messages at different log levels,
associated with certain log domains (define -DG_LOG_DOMAIN for your module).
associated with certain log domains (define -DG_LOG_DOMAIN for your library).
* New inline functions for bit masks tests.
* GNode functions now return the newly allocated node.
* GNode macros (and functions) now return the newly allocated node.
* New macro G_VA_COPY() to work around va_list copying oddities on some
platforms. the non-static g_vsprintf() function vanished in favour of
a publically exported g_strdup_vprintf().
* New utility functions for string and printf-like format handling .
People that used the former g_vsprintf() would definitely want to read the
associated ChangeLog entries (grep for printf).
* New utility functions:
g_strndup(), g_on_error_query(), g_on_error_stack_trace(), g_strdup_printf(),
g_strdup_vprintf(), g_printf_string_upper_bound(), g_spaced_primes_closest(),
g_strnfill(), g_memdup().
* Overhaul of the array implementations, this contains some source incompatible
changes. Again, the ChangeLog is much more informative (grep for garray.c).
* The internals of the g_dataset mechanism are now exported through the
new g_datalist_* API (this is also the underlying implementation for the
keyed data of GtkObjects).
* New function g_atexit(), use of the ATEXIT() macro is discouraged.
* Better configure checks for ansi compliance.
* Libtool update to version 1.2b.
* Lotsa bug fixes and cleanups as always ;)

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.
