The +list below attempts to summarise, but not every change is listed. + +* Major changes to threading and synchronisation + - threading is now always enabled in GLib + - support for custom thread implementations (including our own internal + support for errorcheck mutexes) has been removed + - a whole lot of dead code (to deal with the non-threaded case) has + been ripped out. This includes the racy path of GMainContext that + caused deadlocks with respect to child process exits in + single-threaded programs (such as gtester). + - libgthread is now an empty shell and g_thread_init() is no longer + required (and has been deprecated) + - GMutex and GCond can now be statically allocated without explicit + initialisation. Dynamic allocation for these types is deprecated. + - new types GRecMutex and GRWLock can also be statically allocated + without explicit initialisation. + - GPrivate can now be statically allocated and has an improved API. + Dynamic allocation of GPrivate is deprecated. + - GStaticMutex, GStaticRecMutex, GStaticRwLock, GStaticPrivate are + deprecated. + - GCond now uses monotonic time internally and a new API takes + monotonic time for timed waits, deprecating the wallclock API + - removal of the insane macro indirection used in the previous + implementation of threading and synchronisation APIs + - use SRWLock and CONDITION_VARIABLE APIs when available on Windows + (Vista and later) and emulate them on XP + - leaks of G(Static)Private-allocated data on some cases of thread exit + have been fixed + - simplified new thread creation API with the old API deprecated. The + concept of joinability has disappeared (all threads are joinable) as + have priority levels, 'bound'ness (ie: kernel vs. userspace threads) + and ability to manipulate the stack size. + - GThread is now a refcounted type + - other implementation details changed + +* Move headers for some deprecated functionality to a separate + deprecated/ directory. + +* New support for attribute-based deprecations to issue compiler + warnings instead of breaking the build and/or giving warnings about + implicit declarations (and possibly miscompiling). + +* GCache has been deprecated (after its last use was removed from our + platform over a year ago). + +* It is no longer possible to include individual headers (like + "ghash.h") -- you must #include . + +* The misguided experiment of allowing the program to stumble along with + missing GSettings schemas is now over -- the abort is back. + +* Clarify that fork() is not valid while using GMainContext. This is + because the internal resources of the GMainContext end up being shared + by both processes. We had an assert here but it was breaking existing + (valid) use cases as well, so it has been removed for now. + +* GApplication + - add ::shutdown signal as logical dual to ::startup + - don't use a GMainLoop: iterate the GMainContext directly (improves + quit logic) + +* Several portability fixes for Windows, OpenBSD, Solaris + +* Add new GValue API to specifically deal in signed chars (in case the + platform defines 'char' as unsigned) + +* Use CLOCK_MONOTONIC unconditionally if the libc has support at compile + time (ie: stop checking for kernel support at runtime). + +* SOCKS proxy and resolver improvements + +* Fix the spelling of G_IO_FLAG_IS_WRITABLE (was WRITEABLE) and + introduce a macro for backwards compatibility. + +* GDBus: many code generation updates and improvements + +* GVariant: + - new g_variant_new_from_fixed_array() API + - substantial docs improvements/clarifications + +* mount monitoring is now based on /proc/mounts (where available) + instead of mtab + +* new macros G_SOURCE_CONTINUE and G_SOURCE_REMOVE for returning from + GSourceFunc (so you don't have to remember what TRUE and FALSE mean) + +* use xlocale functions where available to avoid too much heavy lifting + in functions like g_ascii_strtod() + +* GMappedFile can now be created from an fd + +* error message strings grammar/i18n fixes + +* many docs updates + +* Partial list of bugs closed: + 70598 Unify GStaticMutex and GMutex. + 320888 optimization for g_main_context_wakeup + 398418 GChildWatch race condition? + 527214 g_timer_elapsed() returns random values + 580505 add a way to set/get name for a thread + 583511 race condition means g_main_loop_quit() does not work + 592715 Document that g_str_hash() and g_int_hash() are not NULL safe + 631413 Add macros for GSourceFunc return values + 632049 not immediately clear what g_variant_get_fixed_array expects + 640212 "Error stating file" is not a friendly message + 640293 Use xlocale functions to implement g_ascii_strtod() + 640975 Check that error exists before trying to set it + 643934 GApplication lacking a logical dual for the ::startup signal + 651268 assertion failed in GDBus worker thread + 653987 g_key_file_get_integer cannot interpret trailing spaces + 654412 Documentation for g_variant_get_child_value unclear + 654563 info capplet: Failed to calculate disk space + 655366 missing GSettings schemas lead to obscure crashes + 657992 Add glib__private__() API to share between glib,gio + 658188 _set_as_last_used_for_type generates a broken mimeapps.list + 658206 gsocks5proxy.c has invalid gettext use + 658207 glib-compile-schemas says "can not" + 658558 simpleaction: Fix documentation of :enabled + 658683 clean up charset/language threading issues + 658692 add introspection annotations to g_time_val_from_iso8601() + 658715 Duplicite strings + 658769 Invalid reuse of GError in GThreadedResolver + 658806 sign error in string hash implementation + 658976 gdbus-codegen's C namespace option needs to support Ugly_Case + 659070 gdbus-codegen generated code segfaults when property changes + 659082 gdbus-codegen: Single letter namespaces get dropped from names + 659212 GMappedFile should fail on non-regular files + 659324 _SPLICE_CLOSE_TARGET doesn't mark the output stream as closed + 659423 Use adaptive mutexes when available + 659427 Move deprecated code to a separate directory + 659646 gdbus-codegen produce code that warnings at build + 659690 Possible build warning in code generated by gdbus-codegen + 659699 property name collision when generating code for "Connection" + 659754 Add API to GMappedFile that allows to pass FD + 659838 incorrect types in introspection for g_object_bind_property + 659866 pthread_rwlock_t requires defined __USE_UNIX98 + 659870 gvalue: Fix signedness of g_value_get_char() + 659889 glib-2.29.92/gio-2.0.pc.in has a wrong line. + 659920 Missing setter for read/write property 'closed' of GIOStream + 659923 Add g_variant_new_fixed_array() function + 660013 Remove old g_atomic configure cruft + 660096 glib/rwlock tests failure (tests asserted) + 660130 Possible loss of user data when updating mimeapps.list + 660147 tracker causes g_critical in "gsettings list-recursively" + 660413 Make G_ASSERT_STATIC work with clang + 660498 Generated test code fails when the codegen changes + 660511 Use /proc/mounts for monitoring mounts, not /etc/mtab + 660536 Expose options for /etc/fstab entries + 660635 Deprecate g_thread_foreach + 660637 Pending dbus method calls not canceled on connection loss + 660739 kill off g_{mutex,cond}_{new,free}() + 660740 make GThread more standard + 660741 g_cond_timedwait is a disaster + 660743 macro wrappers for g_once_init_enter/leave + 660744 finish killing g_thread_init() + 660745 GPrivate leaks on Windows + 660791 [gio] Improve doc for g_file_make_directory_with_parents() + 660843 asyncqueue-test is broken + 660849 Remove cruft from g_strerror and g_strsignal + 660886 GDBusProxy: don't drop/complain about unknown props/signals + 660887 g_slice_set_config() is broken + 660994 Add g_main_context_ref_thread_default() + 661255 gio: enable test_peer regression test for OpenBSD + 661318 tests use pthread without appropriate compiler/linker flags + 661421 Applications fail to initialize on GNU Hurd - commit + 661438 Implement G_GNUC_DEPRECATED/G_GNUC_DEPRECATED_FOR on Visual C++ + 661763 desktop-app-info: Add support for X-GNOME-Keywords + +* Translations updates: + Belarusian + Brazilian Portuguese + British English + Bulgarian + Catalan + Catalan (Valencian) + Czech + Danish + Esperanto + French + Gujarati + Hebrew + Hungarian + Italian + Lithuanian + Norwegian bokmål + Oriya + Polish + Russian + Serbian + Simplified Chinese + Slovak + Slovenian + Spanish + Tamil + Vietnamese + Overview of changes from GLib 2.29.18 to 2.29.90 ================================================ -- 2.7.4
