Overview of changes from GLib 2.38.0 to GLib 2.39.0
|
||||
====================================================
|
||||
|
||||
* 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
|
||||
