Some desktop file directories, like /usr/local/share/applications may be
missing on some systems.
When we try to inotify on these directories, this will result in a
every-4-seconds poll being setup which is quite bad.
This is an issue that should be fixed in inotify itself but the problem
is much larger there. For now, we can work around it in GDesktopAppInfo
by refusing to monitor missing directories.
We may get some spurious notifications of changes in the case that
/usr/local/share or /usr/local/share/applications is created without
actually adding desktop files, but spurious changes can already be
reported in other cases, so that's OK. We won't get (user-visible)
notification for a simple case of a completely unrelated file being
created (however we cannot avoid the wakeup in this case due to how
inotify works). That's probably pretty theoretical, though, since files
in /usr don't change much and for the home directory we're likely to
have at least ~/.config and ~/.local existing.

We use "tweaks" structures to track how a particular directory impacts
the list of added, removed and default applications. We maintain this
set of tweaks for each directory, in a hash table, keyed by unaliased
mime type name, in order to facilitate fast lookups.
A typo in the logic for creating and maintaining the uniqueness of these
structures was causing the default app to be selected incorrectly from
time to time. Fix that.
Expand the functionality of g_desktop_app_info_set_desktop_env() to
include the possibility of passing strings containing ':' characters (as
some apps, such as gnome-session, are directly passing the value of
XDG_CURRENT_DESKTOP). At the same time, deprecate it, since now we get
the list from the environment variable for ourselves.
Modify the checks in g_desktop_app_info_get_show_in() to deal with
multiple items listed in XDG_CURRENT_DESKTOP. For example, if we find
that we have
XDG_CURRENT_DESKTOP=GNOME-Classic:GNOME
and a desktop file contains:
OnlyShowIn=GNOME
then we will show this file because of the fallback to GNOME. If the
file _also_ contains the line:
NotShowIn=GNOME-Classic
Then we will not show it, because GNOME-Classic comes before GNOME in
XDG_CURRENT_DESKTOP.

Redo the code for type-based selection of applications (all,
recommended, default, fallback) based on the new DesktopFileDir
structures that we introduced last cycle.
At the same time, we expand the functionality to add support for the new
features of the specification:
- moving ~/.local/share/applications/mimeapps.list to ~/.config/
- per-desktop default applications (via XDG_CURRENT_DESKTOP)
- sysadmin customisation of defaults (via /etc/xdg/mimeapps.list)
- deprecation of the old defaults.list, favouring the use of
/usr/share/applications/mimeapps.list (or gnome-mimeapps.list) to
accomplish the same
We modify the mimeapps testcase to check for mimeapps.list having been
created in XDG_CONFIG_HOME instead of XDG_DATA_HOME.
The modification is a net reduction of code (due to less duplication in
bookkeeping). It is also an increase in performance and reduction in
memory consumption (due to simplified data structures). Finally, it
removes the stat-based timestamp checking in favour of the
GFileMonitor-based approach that was already being used in the
implementation of DesktopFileDir (in order to know if we had to rescan
the desktop files themselves).

The app launch context may just not support startup notification,
in which case, g_app_launch_context_get_startup_notify_id() will
return NULL.
Failure to take this into account leads to criticals like this:
gnome-session[8489]: GLib-CRITICAL: g_variant_new_take_string: assertion 'string != NULL' failed
gnome-session[8489]: GLib-CRITICAL: g_variant_new_variant: assertion 'value != NULL' failed
gnome-session[8489]: GLib-CRITICAL: g_variant_get_type: assertion 'value != NULL' failed
gnome-session[8489]: GLib-CRITICAL: g_variant_type_is_subtype_of: assertion 'g_variant_type_check (type)' failed

Add the basename from the first component of the Exec line to the list of
strings to search for via g_desktop_app_info_search().
We treat Exec as a fairly strong match -- just below the visible name.
Add a testcase to make sure everything is working OK.

Since all element markup is now gone from the doc comments,
we can turn off the gtk-doc sgml mode, which means that from
now on, docbook markup is no longer allowed in doc comments.
To make this possible, we have to replace all remaining
entities in doc comments by their replacement text, & -> &
and so on.
Add missing (allow-none) annotations to
g_desktop_app_info_launch_uris_as_manager(). Tested with
python -c "from gi.repository import GLib, Gio; Gio.DesktopAppInfo.new('gcalctool.desktop').launch_uris_as_manager([], None, GLib.SpawnFlags.SEARCH_PATH|GLib.SpawnFlags.STDOUT_TO_DEV_NULL, None, None, None, None)"
which is necessary to do a launch_uris() without leaking stdout.

It makes sense to match on GenericName in case an application does
not provide any keywords, but the Keywords field has been added
to explicitly support the search case, while GenericName was used
to be displayed in menus, so it makes more sense to consider
Keywords more (or equally) relevant for search.

The first time this function is called we load all of the keyfiles in
the directory, ignoring the 'Hidden' ones and build an index out of the
interesting fields using g_str_tokenize_and_fold().
We do prefix matching on the tokens to find relevent desktop files.
Right now this is implemented as a hashtable that we iterate over,
checking prefixes on each token. This could possibly be sped up by
creating an array, but it's already pretty fast...
https://bugzilla.gnome.org/show_bug.cgi?id=711557
In each DesktopFileDir, store a list of desktop files for that
directory. This speeds up opening desktop files by name because we can
skip statting in directories that we know don't have the file and also
speeds up _get_all() because we can avoid enumeration.
This also improves our support for dealing with names like
'kde4/kate.desktop' (equivalent to kde4-kate.desktop) since we find out
about all of these files are the start and don't need to guess about
which '-' to change to a '/'. It also means that we can easily deal
with more than one level of such prefixes.
We use a file monitor to watch for changes, invalidating our lists when
we notice them.

Fix up a lot of whitespace issues in this file since we're about to do
some pretty serious rewriting here anyway...
Add some fold markers while we're at it.
Change the search path to be a global array of 'DesktopFileDir' structures and
change the 'get' function to an 'ensure' function.
This is just a straight-up refactor. Future patches will expand the
DesktopFileDir structure.
Rather than always calling out to g_file_get_path() (which
might block, whatever the documentation might say), postpone
the call until we actually need it.

A previous version of the patch had OnlyShowIn support for desktop file
actions. This was removed from the spec and the patch rewritten, but
this bit of documentation slipped through. Remove it.
For some time, the desktop file specification has supported "additional
application actions". This is intended to allow for additional methods
of starting an app, such as a mail client having a "Compose New Message"
action that brings up the compose window instead of the folder list.
This patch adds support for this with a relatively minimal API.
In the case that the application is a GApplication and DBusActivatable,
desktop actions are translated into GActions that have been added to the
application with g_action_map_add_action(). This more or less closes
the loop on being able to activate an application with an action
invocation (instead of 'activate').

There are two benefits to this:
1) We can centralize any operating system specific knowledge of
close-vs-EINTR handling. For example, while on Linux we should never
retry, if someone cared enough later about HP-UX, they could come by
and change this one spot.
2) For places that do care about the return value and want to provide
the caller with a GError, this function makes it convenient to do so.
Note that gspawn.c had an incorrect EINTR loop-retry around close().

gnome-session needs to know the startup id that was given to
a started app; this was not available via GAppLaunchContext.
This commit adds a ::launched signal to get this information.
At the same time, turn the launch_failed vfunc into a signal
as well.

gnome-session still uses EggDesktopFile, since GDesktopAppInfo is
missing a handful of APIs that are needed to implement the
autostart spec. This patch adds the minimum that is required.
https://bugzilla.gnome.org/show_bug.cgi?id=688497
Many (if not "almost all") programs that spawn other programs via
g_spawn_sync() or the like simply want to check whether or not the
child exited successfully, but doing so requires use of
platform-specific functionality and there's actually a fair amount of
boilerplate involved.
This new API will help drain a *lot* of mostly duplicated code in
GNOME, from gnome-session to gdm. And we can see that some bits even
inside GLib were doing it wrong; for example checking the exit status
on Unix, but ignoring it on Windows.

We need to ignore the defaults.list item only when there
was a mimetype handler found in a previous mimetype, not
if one was found for the same mimetype as the one that
is listed in defaults.list (same for the new-style defaults).
There was an issue when looking up the default handler
for a type where a supertype was listed in defaults.list.
We would pick the default for the parent type even if
there was a handler for the more specific type.
In the case of the new-style defaults marking (
"Default Applications" in mimeapps.list) we were already
checking for a more specific handler befor using a default,
but we also need to do a similar check for the defaults.list
case.
https://bugzilla.gnome.org/show_bug.cgi?id=678944
This essentially adds an accessor for the MimeType field in desktop files,
to retrieve the list of all mime types supported by an application.
The interface though is part of GAppInfo, so it could be implemented
in the future by other backends.

If the launch context is a GAppLaunchContext, and not a
GdkAppLaunchContext, then g_app_launch_context_get_display will return
NULL because the get_display virtual method is undefined. The DISPLAY
might still be inherited from the parent process, in which case
overwriting it with NULL breaks the launch.
This is a regression introduced in:
