glib-2.74.0

[Douglas R. Reno]

New minor version

[Xi Ruoyao]

One significant change in this release is glib now depends on pcre2, instead of pcre.

[Xi Ruoyao]

Testsuite needs LC_ALL=C or glib / spawn-test fails (with LANG=zh_CN.UTF-8 on my system).

2.73.1

Overview of changes in GLib 2.73.1

  finding which iconv implementation to use (work by Eli Schwartz) (!2734)

  source (work by Philip Withnall) (!2733)

  Benjamin Berg) (#1941)

2.73.2

Overview of changes in GLib 2.73.2, 12-07-2022
==============================================

* Replace PCRE1 with PCRE2: This is a major change to drop the libpcre1
  dependency and use libpcre2 instead, while preserving the behaviour and API of
  GRegex. G_REGEX_OPTIMIZE and G_REGEX_JAVASCRIPT_COMPAT are now deprecated
  and became a no-op, while other flags are adapted accordingly to the new API
  (work by Aleksei Rybalkin, Philipp Withnall) (!2529, #1085)

  objects disposal (work by Peter Bloomfield) (!2776, #2672, #2676)

  Trevisan) (!2766)

  (!2788)

2.73.3

Overview of changes in GLib 2.73.3, 05-08-2022
==============================================

* Revitalize G_REGEX_OPTIMIZE flag and use it to enable PCRE JIT compiler (work
  by Aleksei Rybalkin) (!2817)

* Fix some regressions due to the PCRE2 port (work
  by Aleksei Rybalkin, Mamoru TASAKA and Marco Trevisan) (!2814, !2827, #2694,
  #2699, #2700)

* Fix a pidfd leak that was introduced in the previous release (work by
  Christian Hergert) (#2708)

* Support compilation without a C++ toolchain (work by James Hilliard) (!2822)

* GDBus: Use namespace-friendly protocol for Linux message buses, and optionally
  other connections (work by Simon McVittie) (!2832)

* Fix potential races in multi-threaded signal connections handling (work by
  Marco Trevisan) (!2823)

* Add back gio-launch-desktop to redirect stdout/stderr of launched
  GDesktopAppInfo's to the journal with proper parent (work by Simon McVittie)
  (!2818, !2819, #2682)

* Executables that are invoked when installing other software, typically
  from packaging system triggers, can now be installed into
  architecture-dependent locations. Unix OS distributors who install
  GLib for more than one architecture in parallel (multiarch or multilib
  installations) should consider building with -Dmultiarch=true, installing
  the bin/glib-compile-schemas and bin/gio-querymodules symbolic links in
  packages for the primary architecture, and omitting those symlinks from
  packages for secondary architectures. (work by Simon McVittie) (!2818)

* Some enumerators introduced in previous releases have been changed, for better
  introspection results:
  - G_MARKUP_PARSE_FLAGS_NONE renamed to G_MARKUP_DEFAULT_FLAGS
  - G_TLS_CERTIFICATE_FLAGS_NONE renamed to G_TLS_CERTIFICATE_NO_FLAGS
  - G_APPLICATION_FLAGS_NONE was deprecated, use G_APPLICATION_DEFAULT_FLAGS now
  (work by Emmanuele Bassi) (!2835)

* gfileinfo: Implement xattr attribute removal (work by madmurphy) (#1187)

* Add support to --delete option to gio set, to unset a file attribute (work by
  codeboybebop) (#2588)

* Improve default value of glib_debug option: G_ENABLE_DEBUG will be defined
  only if using `--buildtype=debug` or enabled via `-Dglib_debug`, but it
  won't ever be set if an optimized build is requested (specifically if the
  optimization level is not `0` or `g`) as it may be the case when using
  `--buildtype=debugoptimized` (work by Michael Catanzaro) (!2851)

* Probably the first revision of any GNOME module ever released from Cuba :)

* Bugs fixed:
 - #566 support using the PCRE JIT
