glib 2.39.0

About GLib
==========

GLib is the low-level core library that forms the basis for projects
such as GTK+ and GNOME. It provides data structure handling for C,
portability wrappers, and interfaces for such runtime functionality as
an event loop, threads, dynamic loading, and an object system.

News
====

 * prep for the 2.40 series (version macros, docs index, etc.)

 * GNotification

   - new API for sending persistent notifications via the desktop shell

   - notifications persist when the application has quit and clicking on
     them can restart the application with an action (via
     DBusActivatable)

 * GSubprocess

   - new API for launching subprocesses

   - nice GIO integration like async functions, cancellability, etc.

   - a convenient communicate() API inspired by the same API in Python

   - related: the gspawn API now has a CLOEXEC flag for the created
     pipes for stdin/stdout/stderr

 * New gapplication(1) commandline tool

   - intended to be used with DBusActivatable apps

   - can be used for launching apps, opening files, invoking application
     actions and listing apps and actions

   - bash tab completion is supported

 * GDesktopAppInfo changes:

   - g_file_get_path() can implicitly cause a FUSE mount so don't call
     it until we know we need it (for an app that doesn't support URIs)

   - don't crash when trying to load from a keyfile with
     DBusActivatable=true

   - remove some dead code, refactor the search path handling a bit and
     do a large-scale whitespace cleanup (prep work for the pending
     desktop file index)

 * File monitors

   - fix broken handling of mount point monitoring

   - remove some strange use of GObject::constructor() from the base
     class and inotify backend

   - fix GFileMonitor to work in the non-default main context even when
     the main context is not running (or is blocked)

   - add internal private API for easily creating a file monitor in the
     GLib worker thread

 * GSettings

   - g_settings_list_children: only list viable schemas.  This fixes a
     longstanding issue where 'gsettings list-recursively' will crash
     when there are invalid schemas installed

   - don't accept invalid paths on g_settings_new_with_path, etc.

 * GIO

   - GFile now has a thumbnail::is-valid attribute to check if the
     thumbnail in thumbnail::path needs to be regenerated

   - GDBusProxy now has a flag to control autostarting of services at
     construction time

   - for GSeekable, properly introduce the concept of "resizable" vs.
     "fixed-sized" streams in the docs, explaining the expected
     semantics of the interface in each case

   - fix some cases in GMemoryOutputStream that were violating the above
     expectations (which may cause a slight API incompatibility)

   - clean up GCredentials code and add support for Hurd and Solaris

   - improve splicing by using different codepaths for the case where we
     have real _read_async() and _write_async() implementations on the
     stream vs. the case where they are internally emulated (via
     dispatching the sync variant of the call in a thread)

 * GKeyFile

   - fix a leak in g_key_file_get_(u)int64 when we fail to parse the
     value as an integer

   - add long-requested API g_key_file_save_to_file()

 * Portability improvements

   - avoid using O_DIRECTORY on platforms that don't have it

   - be careful about systems that define SOCK_CLOEXEC but don't
     actually support it (like Hurd)

   - only use SA_RESTART if it exists

 * Other small API changes/additions

   - a pair of functions to support matching strings for the type of
     search functionality that you'd expect to have with things like
     GtkSearchBar.  This will also be used by the desktop file index.

   - g_str_is_ascii() with obvious purpose

   - g_test_expect_message() no longer appears to allow you to catch
     G_LOG_ERROR messages

 * GMainContext/GSource

   - fix handling of overflowing the 'next source id' counter

   - g_source_remove() will not throw a critical in the case that you
     try to remove a non-existent source.  We expect that there is some
     code in the wild that will fall afoul of this new critical but
     considering that we now reuse source IDs, this code is already
     broken and should probably be fixed.

   - simplify handling of the 'current dispatching source' to not
     require use of a linked list

 * GObject

   - the long-broken (and leaky) pattern of destroying a just-allocated
     object from inside of a custom GObject::constructor is now
     officially completely illegal and will abort the program

 * Unicode: update to 6.3.0

 * Bug fixes

   - g_file_copy() now falls back to pathname queryinfo.  This should
     clear up the bugs with copying from some GVfs backends (afp,
     gphoto, archive, at least).

   - fix an out-of-bounds read in the xdgmime code

   - fix a typo in the /org/freedesktop/DBus path on the object manager
     client

   - skip emitting path_namespace='/' in match rules in order to
     workaround a bug in the D-Bus daemon and fix our own implementation
     (which shared exactly the same bug)

   - fix crashes on precondition violations for GParamSpec constructors

   - many other small fixups (see bug list)

  * Many documentation improvements
