cdf0a50c69 gdesktopappinfo: Fix validation of XDG_CURRENT_DESKTOP
Split out XDG_CURRENT_DESKTOP handling to a separate function and make
sure that it drops all the invalid entries properly. Earlier a bad
entry could slip through the checks by sitting just after another bad
entry, like in env being set to `invalid1!:invalid2!`, where
`invalid2!` could slip the checks.

88fe78137d gdesktopappinfo: Fix unnecessarily copied and leaked URI list
When an app is spawned using g_desktop_app_info_launch_uris_with_spawn
it will expand the various token in the app's commandline with the
URIs of the files to open. The expand_macro() function that is used for
this advances the pointer to the URI list to show up to which entries
it used.

To not loose the pointer to the list head a duplicate of the URI list
was actually passed to expand_macro(). However, it's not necessary to
create a copy of the URI list for that as expand_macro() will only
change which element the pointer will point to.

This behaviour actually caused the duplicated list to be leaked as the
the list pointer is NULL once all URIs are used up by expand_macro()
and thus nothing was freed at the end of the function.

00bfb3ab44 tree: Fix various typos and outdated terminology
This was mostly machine generated with the following command:
```
codespell \
    --builtin clear,rare,usage \
    --skip './po/*' --skip './.git/*' --skip './NEWS*' \
    --write-changes .
```
using the latest git version of `codespell` as per [these
instructions](https://github.com/codespell-project/codespell#user-content-updating).

Then I manually checked each change using `git add -p`, made a few
manual fixups and dropped a load of incorrect changes.

There are still some outdated or loaded terms used in GLib, mostly to do
with git branch terminology. They will need to be changed later as part
of a wider migration of git terminology.

If I’ve missed anything, please file an issue!

2b533ca99a gdesktopappinfo: Use sh rather than gio-launch-desktop
There were some problems about where to install `gio-launch-desktop` to
support multiarch systems without circular dependencies. Simon McVittie
suggested that, actually, given the current set of platforms supported
by `GDesktopAppInfo` (they’re all POSIX), we could just use `sh`.

That simplifies things nicely. `gio-launch-desktop` can always be
resurrected (and the multiarch debate continued and resolved) if needed
in future.

bffe058550 gdesktopappinfo: Allocate DesktopFileDir structs dynamically
`DesktopFileDir` pointers are passed around between threads: they are
initially created on the main thread, but a pointer to them is passed to
the GLib worker thread in the file monitor callback
(`desktop_file_dir_changed()`).

Accordingly, the `DesktopFileDir` objects either have to be
 (1) immutable;
 (2) reference counted; or
 (3) synchronised between the two threads
to avoid one of them being used by one thread after being freed on
another. Option (1) changed with commit 99bc33b6 and is no longer an
option. Option (3) would mean blocking the main thread on the worker
thread, which would be hard to achieve and is against the point of
having a worker thread. So that leaves option (2), which is implemented
here.

5ca9eca632 gdesktopappinfo: add get_string_list() function
The X-Flatpak-RenamedFrom key is used in .desktop files to identify past
names for the desktop file. It is defined to be a list of strings.
However, there was previously no correct way to retrieve a list of
strings from the GKeyFile wrapped by GDesktopAppInfo, short of
re-parsing the file with GKeyFile.

Note that doing something like:

    g_strsplit (g_desktop_app_info_get_string (...), ";", -1)

is not correct: the raw value "a\;b;" represents the one-element list
["a;b"], but g_key_file_get_string() rejects the sequence "\;", and so
g_desktop_app_info_get_string() returns NULL in this case. (Of course, a
.desktop file with a semicolon in its name is a pathological case.)

Add g_desktop_app_info_get_string_list(), a trivial wrapper around
g_key_file_get_string_list(), similar to g_desktop_app_info_get_string()
and co.

The change from g_key_file_free() to g_key_file_unref() in the test is
needed because g_key_file_free() clears the contents of the keyfile.
This is fine for all the fields which are eagerly loaded and copied into
GDesktopAppInfo, but not when we want to access arbitrary stuff from the
keyfile.

d501bd0dbe gdesktopappinfo: Gracefully handle NULL URIs when passed to expand_macro()
If an application calls g_app_info_launch_uris() with a GList that includes
NULL values in some of its data members, and GIO ends up internally calling
g_desktop_app_info_launch_uris_with_spawn() for whatever reason (e.g. no
D-Bus session available), expand_macro() will crash due to the invalid data.

As this is considered a programmer error, use g_return_val_if_fail() in those
situations to prevent the crash from happening, but printing a warning anyway.

e5ed410c8c Avoid calling Standard C string/array functions with NULL arguments
glibc string.h declares memcpy() with attribute(nonnull(1,2)), causing
calls with NULL arguments to be treated as undefined behaviour.
This is consistent with ISO C99 and C11, which state that passing 0
to string functions as an array length does not remove the requirement
that the pointer to the array is a valid pointer.
gcc -fsanitize=undefined catches this while running OSTree's test suite.

Similarly, running the GLib test suite reports similar issues for
qsort(), memmove(), memcmp().

3301b852a2 GDesktopAppInfo: support bus activation with '-'
GApplication has accepted any valid bus name as an application ID since
before the time of D-Bus activation.  This includes bus names with '-'.
Several applications have even attempted support bus activation with
these names, going as far as installing D-Bus service files, without
realising that they are silently falling back to fork()/exec() on
account of the name containing a dash.

The reason for the problem is that D-Bus object paths cannot contain
dashes.  We solved this problem privately in an unspecified way inside
of GApplication but substituting '_' in this case, but never made this
part of the Desktop Entry Specification.

The fact that these apps with '-' in the desktop file names aren't
actually using D-Bus activation is beside the point: their intent here
was clear.  Let's avoid forcing them to rename their desktop files again
by simply accepting '-' in desktop file names and munging the path in
the way that GApplication did so historically.

The new path escaping code here has been copied more or less verbatim
from GApplication's own code for the same purpose, with only the removal
of one irrelevant part.

An update to the desktop entry specification will follow.

2bb898c60f app info: tweak default application algorithm
Always run the full algorithm for a given mime type before considering
fallback types.

This includes considering installed applications capable of handling a
particular mimetype, even if such an app is not explicitly marked as
default, and there is a default app for a less-specific type.

Specifically, this often helps with cases of installing apps that can
handle a particular subtype of text/plain.  We want to take those apps
in preference to a generic text editor, even if that editor is listed as
the default for text/plain and there is no default listed for the more
specific type.

Because of the more holistic approach taken by the algorithm, it is now
more complicated, but it also means that we can do more work while
holding the lock.  In turn, that lets us avoid duplicating some strings,
which is nice.

2737ab3201 substantially rework file monitors
Remove all event merging and dispatch logic from GFileMonitor.  The only
implementation of GFileMonitor outside of glib is in gvfs and it already
does these things properly.

Get rid of GLocalDirectoryMonitor.  We will use a single class,
GLocalFileMonitor, for both directory and file monitoring.  This will
prevent every single backend from having to create two objects
separately (eg: ginotifydirectorymonitor.c and ginotifyfilemonitor.c).

Introduce GFileMonitorSource as a thread-safe cross-context dispatch
mechanism.  Put it in GLocalFileMonitor.  All backends will be expected
to dispatch via the source and not touch the GFileMonitor object at all
from the worker thread.

Remove all construct properties from GLocalFileMonitor and remove the
"context" construct property from GFileMonitor.  All backends must now
get the information about what file to monitor from the ->start() call
which is mandatory to implement.

Remove the implementation of rate limiting in GFileMonitor and add an
implementation in GLocalFileMonitor.  gvfs never did anything with this
anyway, but if it wanted to, it would have to implement it for itself.
This was done in order to get the rate_limit field into the
GFileMonitorSource so that it could be safely accessed from the worker
thread.

Expose g_local_file_is_remote() internally for NFS detection.

With the "is_remote" functionality exposed, we can now move all
functions for creating local file monitors to a proper location in
glocalfilemonitor.c

Port the inotify backend to adjust to the changes above.  None of the
other backends are ported yet.  Those will come in future commits.

5a0a85e444 gdesktopappinfo: Fix copy/paste typo from e24e89b
Commit e24e89b accidentally ironically introduced a typo when replacing
the code with symbolic contents. Specifically, "Added Associations" was
replaced with "Default Applications" when reading defaults.list, giving
a warning about the file containing a "Default Applications" group.

If this was intended, it should have not been lumped in with a cleanup.

3b8bc8bacf GDesktopAppInfo: avoid inotify on missing dirs
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.

08efbda733 GDesktopAppInfo: fix default app logic
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.

5a5e16e93c AppInfo: use XDG_CURRENT_DESKTOP for OnlyShowIn
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.

6fd5a8cdaa GDesktopAppInfo: rewrite content type code
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).

86ce3bf48e gdesktopappinfo: keep a list of files in the dirs
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.

6dc5c118e4 Implement the Desktop Action specification
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().

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.
