This is a follow-up to commit 614adf8a75,
which started generating two new files as part of the test; they need to
be cleaned up before distcheck will pass.
Ideally, the test should run a temporary directory and wipe that
directory itself before exiting, but that’s a bit of a big change to
make right now. Deferred to

In file gio/gtestdbus.c, function watch_parent, there is a loop which
waits for commands sent from the parent process and kills all processes
recorded in 'pids_to_kill' array on parent process exit. The detection
of parent process exit is done by calling g_poll and checking whether
the returned event is G_IO_HUP. However, 'revents' is a bit mask, and
we should use a bitwise-AND check instead of the equality check here.
It seems to work fine on Linux, but it fails on FreeBSD because the
g_poll returns both G_IO_IN and G_IO_HUP on pipe close. This means the
watcher process continues waiting for commands after the parent process
exit, and g_io_channel_read_line returns G_IO_STATUS_EOF with 'command'
set to NULL. Then the watcher process crashes with segfault when calling
sscanf because 'command' is NULL. Since the test result is already
reported by the parent process as 'OK', this kind of crash is likely to
be unnoticed unless someone checks dmesg messages after the test:

If the watcher process crashes before killing the dbus-daemon process
spawned by the parent process, the dbus-daemon process will keep running
after all tests complete. Due to the implementation of 'communicate'
function in Python subprocess, it causes meson to crash. 'communicate'
assumes the stdout and stderr pipes are closed when the child process
exits, but it is not true if processes forked by the child process
doesn't exit. It causes Python subprocess 'communicate' function to
block on the call to poll until the timeout expires even if the test
finishes in a few seconds. Meson assumes the timeout exception always
means the test is still running. It calls 'communicate' again and
crashes because pipes no longer exist.

Previously, glocalfile.c would not set file system metadata for
the free/used key for file systems which reported 0 free space. This is
because some file systems don’t set that metadata when you call
statfs(), so we can’t reliably report it. However, some do, and they
can legitimately set f_bavail and f_bfree to 0 if the file system is
full.
In order to avoid that, always set the file system metadata unless the
file system is FUSE or ncpfs.
This is a partial revert of commit 0b9f24c1e1: instead of the changes
made in that commit, I think we should maintain a blacklist of file
systems which are known to not correctly report free space.

Similar issue was fixed with commit f929d148, but it's happening again.
Define G_MESSAGES_DEBUG=all when running CI to ensure we won't regress

In order to determine whether to trash a file to the home directory, we
compare its st_dev to our home directory's st_dev field.
This is the wrong thing to do on overlayfs when deleting files, because
st_dev contains the ID of the filesystem providing the file (which can
be the lower or upper filesystem), but directories always return the ID
of the overlayfs. Thus the comparison fails and we are unable to trash
the file.
Fix this by checking st_dev of the parent directory when we are deleting
a file.
Also adjust `test_trash_not_supported` for this - make its st_dev check
look at the parent directory's `st_dev` rather than the temporary file's
own.
Fixes#1027.

On Windows st_ctime field is the file creation time.

We now send the fallback SCSV, meaning use of this function will cause
modern servers to immediately terminate the connection, so let's warn
API users to expect that behavior and be crystal clear that this
function should only be used as a fallback when a normal connection
attempt has already failed.
Also, the documentation is mostly duplicated between the property and
the function, so let's just reference the function documentation from
the property.
7efd76dd67 added these configure time tests to work around a bug
with older Android. Since the test didn't take Windows into account it
wrongfully applied the workaround on Windows too, breaking the build.
With meson this wasn't an issue since the check is skipped on Windows there
and our CI didn't catch this issue.
Change the test to run on Android only for meson and autotools.
This also makes it clear that the test+code can be dropped again if we stop
supporting older Android versions at some point.
GLib currently tries to use FAM volume monitor for monitoring files
within home on NFS. If FAM support is not available, it fallbacks by
default to GInotifyFileMonitor. I think we should fallback to
GPollFileMonitor instead, because inotify is not reliable on NFS,
which may cause issues for dconf. With this patch, it should be safe to
not build libgiofam and still be sure that dconf works properly if home
is mounted on NFS. I think this might be a first step to remove FAM
support from GLib completely, because gamin is buggy and dead for
several years already. Gamin just polls files on NFS anyway. This
change applies on files only, because GPollFileMonitor seems doesn't
support dirs, however it should be enough for dconf. The other
drawback is that one can't set poll timeout currently. Just a note
that this can still be overwritten by GIO_USE_FILE_MONITOR.
Releasing GVolumeMonitor before g_volume_mount finish cause that
g_volume_get_mount returns NULL, because the mount is not correctly
propagated to the volume.

The gresource code uses libelf if available but that also depends on mmap but isn't
guarded with HAVE_MMAP. This can make the build fail under MSYS2 where a mingw version
of libelf exists but there is no mmap.
Instead of guarting the libelf code with HAVE_LIBELF add a new macro named USE_LIBELF
which is only defined if libelf and mmap support are available.
Also install the mingw libelf version for CI so we catch similar errors in the future.
It is a bug if we distribute files which are generated at build time —
they should be built on the machine which is compiling GLib, not be
shipped in the tarball.

ninja-generated one, with the exception of man pages and gtk-doc HTML

The new python module, added with 0.46, works with Python 2 and 3 and
allows to pass a path for the interpreter to use, if the need arises.
Previously the meson build set PYTHON, used in the shebang line of
the scripts installed by glib, to the full path of the interpreter.
The new meson module doesn't expose that atm, but we should set it to
a executable name anyway, and not a full path.
Several of our tools are installed and are used by other projects to
generate code. However, there is no 'install' when projects use glib
as a subproject.
We need some way for glib to 'provide' these tools so that when some
project uses glib as a subproject, find_program('glib-mkenums') will
transparently return the glib-mkenums we just built.
Starting from Meson 0.46, this can be done with the
`meson.override_find_program()` function.
As a bonus, the Meson GNOME module will also use these
'overriden'/'provided' programs instead of looking for them in PATH.

check_expected_events is heavily modified in this commit to tolerate
event loss and allow renaming to be reported as creation and deletion.
This fixes test failure on FreeBSD.
Previously, kqueue file monitor only add event sources for directories
regardless of the type of the file being monitored. Doing so may be
possible on inotify, but it is not sufficient on kqueue. Watching a
directory on kqueue doesn't report changes made to files under it, and
we must watch files themselves to get notified. This problem is fixed
by adding a second watch for non-directory file monitors, and the result
is that we are now able to receive 'CHANGED' and 'ATTRIBUTE_CHANGED'
events for non-directory files.
Since having two watches on one file monitor requires many code changes
to work properly, this commit also changes the following things:
- NOTE_ALL macro is now replaced by note_all inline function. Since the
kqueue backend is shared by all BSD operating systems, there are a
few difference between these systems. It is easier to do '#ifdef'
check in a function than in a macro.
- Both g_kqueue_file_monitor_callback and g_kqueue_file_monitor_cancel
now holds a lock before accessing kqueue_sub structs. This fixes a
crash when these two functions are called from different threads,
causing g_kqueue_file_monitor_callback to access freed memory.
- 'mask' variable in g_kqueue_file_monitor_callback is now removed.
The usage of 'mask' was wrong because of the 'mask > 0' check.
'CHANGED' event has value 0 so the 'mask > 0' check made it
impossible to emit 'CHANGED' events.
- kqueue-missing scans can now be triggered from the kqueue event
callback instead of always waiting for 4 seconds.
- Don't remove a file from kqueue on unlink unless its hard link count
has dropped to zero.
- Don't use 'else if' in the check of 'fflags'. It is possible for a
kevent to have multiple flags set.
- Don't use g_file_monitor_emit_event directly. Always use
g_file_monitor_source_handle_event to report events.
Events submitted to g_file_monitor_emit_event are delivered
immediately, but events sent to g_file_monitor_source_handle_event
are scheduled by GLocalFileMonitor. If we mix the two, the order of
events will be wrong and tests will fail.
- Report 'CHANGES_DONE_HINT' immediately after 'CREATED' if the file
created is not a regular file. This is copied from ih_event_callback.
GVfs utils used to have bash completion, which was pretty useful. However,
it hasn't been ported to gio tool unfortunately. GLib provides completion
for various utils already, so it would be nice to provide completion also
for gio tool. I've updated old bash completion code and merged with some
my old unmerged fixes.
The gvfs completion used "gvfs-ls --show-completions" helper. This mentioned
option hasn't been obviously ported to "gio list" and the proposed completion
doesn't add this option in "gio list" to not pollute the codes, but maybe it
is a bit slower as consequence.
The proposed bash completion suggests subcommands, uris and paths including
the remote mounts. It contains some workarounds, especially because of proper
handling of paths with colons and other special chars (like spaces)...
Since it’s deprecated in favour of positional arguments, including it in
the help output is confusing.

This is useful for projects who want to describe their D-Bus interfaces

Previously, calling:
g_dbus_is_supported_address ("some-imaginary-transport:", NULL)
correctly returned FALSE; but calling:

crashed with:
GLib-GIO:ERROR:../gio/gdbusaddress.c:434:g_dbus_is_supported_address:
assertion failed: (ret || (!ret && (error == NULL || *error != NULL)))
This was because, if the address component did not start with a known
transport, no error was set. Fix this, reusing an error string used by
the corresponding else branch in g_dbus_address_connect(), and adjust
the test to pass both NULL and non-NULL GError **s to this function in
every test case. This case:
g_assert (!g_dbus_is_supported_address ("some-imaginary-transport:foo=bar;unix:path=/this/is/valid", NULL));
would have caught this bug with a non-NULL GError **.
The way things were before: a FreedesktopNotification struct is
allocated before the dbus call, and this same struct is possibly re-used
for other dbus calls. If the server becomes unavailable, the callback
will be invoked after the call times out, which leaves a long time where
other dbus calls can happen, re-using the same FreedesktopNotification
as user data. When the first call times out, the callback is invoked,
and the user data is freed. Subsequent calls that used the same user
data will time out later on, and try to free a pointer that was already
freed, hence segfaults.
This bug can be reproduced in Cinnamon 3.6.7, as mentioned in:
<https://github.com/linuxmint/Cinnamon/issues/7491>
This commit fixes that by always allocating a new
FreedesktopNotification before invoking dbus_call(), ensuring that the
callback always have a valid user data.

On an Android build, API 22, at least, I got a:
> warning: "UNIX_PATH_MAX" redefined
We were currently defining it as:
> #define UNIX_PATH_MAX sizeof (((struct sockaddr_un *) 0)->sun_path)
Whereas Android's headers define this variable of sockaddr_un as:
> char sun_path[UNIX_PATH_MAX];
So by definition, we will still get the right result in the end by just
using the original value of UNIX_PATH_MAX.
C_IN macro was added years ago in bcbaf1bef0, using same value as the
internal code of Android with the reasonning that "some parts of the API
used by the resolver objects is not public in the Android NDK (yet)".
Well since then things are changed, since it is definitely available (at
least on the API 22 of Android which I am using) in the public header
arpa/nameser_compat.h.
Let's just add a #ifndef to handle both cases when you build with an
older or recent API.
Meson has the ability to classify tests according to "suites", a list of
tags. This is especially useful when we want to run specific sets of
tests — e.g. only GLib's tests — instead of the whole test suite. It
also allows us to classify special tests, like "slow" ones, so that we
can only run them when needed.
FIONREAD ioctl on Linux reports the size of payload on UDP sockets.
However, other systems usually add internal header size to the reported
size, which vary between different operating systems and socket types.
To make it work on more systems, we should follow what we do on Windows
instead of using this unreliable FIONREAD ioctl.
This fixes socket test on FreeBSD.
libelf, just like libc, is not a single project. It is an interface
which can be implemented independently by different operating systems.
Therefore, we cannot expect all systems to provide a .pc file, and we
should fallback to cc.find_library and cc.has_function like what we
already do in autotools build.
Non-glibc gettext implementation seems to decide the language from
LC_MESSAGES environment variable instead of LC_MESSAGES locale, so
we should set both environment variable and locale when running tests
which need translation from specific languages.
G_IO_ERROR_NOT_SUPPORTED is used as parameter for g_set_io_error(),
however, errno is expected instead and thus error code is set to 0,
which is wrong. Let's use ENOTSUP instead.
To be honest, I am not sure why, but in some special environments (e.g.
our CI integration) can happen, that file device number is different from
parent device number. Return "Unable to find or create trash directory for
%s" error from g_local_file_trash() in that case and also set

This happens because the trash backend doesn't monitor files on system

Main changes were:
- take into account that style variants are added to the list of icon
names.
- In the test of icons set with 3 names ("first", "testicon" and
"last"), I also changed "first" to "first-symbolic" so that we can
test in such a case that the variant is the regular icon (only for
this name, out of the 3).
- Finally icon hashes are necessarily changed, and since emblems are
sorted by their hash in emblem icons, I had to invert an order which
was now different in one of the tests.
... a theme icon.
Otherwise fallbacks of the added icon name are not added to the list (if
use-default-fallbacks is set), nor is the regular/symbolic variant. Also
if we do not recreate the finale list from scratch, sorting of icons and
their variants may end up wrong.
To this end, let's keep around the icon names used for initialization,
separate from the finale name list.
When a themed icon is constructed with several input icon names, add the
variants (symbolic as well as level fallbacks) for every icon names, not
only the first one.
The search order is: first icon name, then its level fallbacks, then
second icon name, then its level fallbacks, then all style variants
(symbolic or regular, opposite to requested style) keeping the same
order again.
This fixes the contenttype GIO unit test.
Whatever the preferred icon style is (symbolic, regular or the requested
style), fallbacking to the other style in case of absent variant is
better than not finding any icon at all.
Also style fallbacking should be managed separately from property
"use-default-fallbacks". Default fallbacks are meant for the process of
getting up in context levels (as separated by dashes in icon name). Even
though it also uses dash characters in format, this is a different
concept as the variant of styles.
Without this commit for instance, if an icon only had a symbolic
variant, and the theme had "-gtk-icon-style" set to "regular" while your
GTK+ application requested the regular icon name, you were getting no
icons, and the application would look completely broken.
Now one would at least fallback to the symbolic icon as last resort
(which is infinitely better than having no icons).
Autoconf macro AC_HEADER_MAJOR doesn't define a macro in config.h when
major is defined in sys/types.h. This was not a problem because major
is assumed to be always available. However, commit aefffa3fbc
changes this assumption in order to fix build on systems without major,
which causes code using major to be disabled on systems putting major
in sys/types.h.
This commit defines a new macro MAJOR_IN_TYPES for both autotools and
meson builds to make major useful on these systems again.
gio-querymodules-wrapper.py is copied from glib-networking. This python
wrapper script is needed because meson.build cannot check for DESTDIR
env variable itself, unlike Makefile.am. It is used to update
giomodule.cache file when installing GIO modules like fam.
The previously implementation considered a file to be a mountpoint if
its parent is on a different device. / is its own parent, so by this
definition it is not a mountpoint.
But / is (generally) listed in fstab, and fstab(5) defines the
directories it contains to be mountpoints. This attribute should follow
that definition (and reasonable expectation): the root directory is a
mountpoint.
So, add a special-case for the case where the file's parent has the same
st_dev and st_ino as the file, which is true only at the root.
Test this attribute at / (only on POSIX), /proc (but only on Linux), and
at many files and directories created by the test suite (which cannot be
mountpoints).
Sometimes file monitor events may be slow to emit. Using g_idle_add
makes it less possible for events to be scheduled later than the main
loop quit, preventing test failure caused by missing events.
This fixes test failure on FreeBSD.
The check in _ke_is_excluded, which causes GKqueueFileMonitor to
fallback to GPollFileMonitor when it returns TRUE, was made to prevent
file monitor from blocking unmount of removable drives on systems not
supporting O_EVTONLY flag in open. However, since g_mount_can_unmount
always returns TRUE on Unix-like platforms, the check always returns
TRUE on non-standard mount points, which is very likely to cause all
programs on the desktop to use the polling fallback if GNOME is
installed in a different prefix for development. This makes the desktop
sluggish and results in bad developer experience on *BSD.
Kqueue isn't good at detecting rapid file creation and deletion. It
tends to miss events because events returned by the kernel don't include
filename information. Since the size of struct kevent is fixed, it is
probably not possible to extend the API to include file names without
breaking ABI. Therefore, we disables the test here to avoid test failure
that is impossible to fix in a reliable way.
The test 'file' uses non-standard '--bytes' option when running du,
which may cause error on non-GNU systems. To keep the test working,
we skips the du check as if we don't find a du command when du fails.
-export-dynamic is a libtool flag. It is also supported by GCC as an
undocumented flag, but it is not supported by Clang. Since we don't use
libtool in meson, we should use -Wl,--export-dynamic instead.
In master, it is already possible to build GLib using Visual Studio
using Meson[1] for some time, so we should focus on maintaining only the
Meson build files for building GLib with Visual Studio.
[1]: There are caveats when building with Visual Studio 2008, namely
that one needs to use the mt command to embed the manifests that
are generated with the .exe/DLLs, for all builds, and that in the
case where the compilation hangs on Visual Studio 2008 x64, as a
workaround, should stop the build by terminating all cl.exe tasks
and change the compiler optimization flag from /O2 (full speed) to
/O1 (optimize for size), due to compiler optimization issues.
Change G_FILE_ATTRIBUTE_ACCESS_CAN_TRASH logic to be consistent
with recent g_local_file_trash changes, i.e. set this to FALSE for

New bugs appears periodically in nautilus/gvfs/glib components that not
all trashed files are shown in trash:///. It used to be problem mostly
for "bind mounts" and btrfs subvolumes only. Currently, it is also
problem for nfs, cifs and other filesystems, which have been recently
added by commmit 0d69462f on the list of system internal filesystems.
This happens because the trash backend doesn't monitor files on system
internal mounts. Such behavior is not against the trash-spec, however,
we should be consistent within GNOME.
This behavior has the nice side-effect that it solves issues with hangs
on network filesystems: https://gitlab.gnome.org/GNOME/glib/issues/605,
because those are currently on the system internal filesystem list.

Commit faf9440908 made the bash completion more

Remove the error case when --dest is not specified. To keep the completion

completion after --session/--system/--address have been supplied, so we can
complete its argument. Additionally, if --dest isn't specified then we can't
complete --object-path or --signal, so guard these completions accordingly.

When completing, we parse the options that the user has typed so far. Up
until now we've been doing this without ignoring unknown options. This
leads to broken completions when the user has typed an incomplete
parameter.
For example, when doing the following:
$ gdbus emit --session --obj<tab>
We expect --object-path to be completed, but it is currently not. What
happens is that we fail to parse the options, therefore don't act on
--session and so don't connect to the session bus, then we early-exit
because we need to know which bus to operate on for later completions.
Instead we can ignore the half-completed --obj, parse --session, get
connected to the bus and then move on to the later completion code.

Building against libmount installed into a non-default prefix wasn’t
working, as we were using #include <libmount/libmount.h> rather than
the correct #include <libmount.h> — all the mount.pc pkg-config files
set `Cflags: -I${includedir}/libmount`.
Fixing this while retaining the fallback support for versions of
libmount without a pkg-config file would have been tricky (we would need
to work out a suitable -I flag to set in LIBMOUNT_CFLAGS) to still be
able to use the correct #include path). Thankfully, libmount gained
pkg-config support a long time ago, so I think we can safely drop the
fallback code. In particular, Debian Jessie, Ubuntu Trusty, and CentOS 5
all ship a mount.pc file.

res_query() uses global state in the form of the struct __res_state
which contains the contents of resolv.conf (and other things). On Linux,
this state seems to be thread-local, so there is no problem. On OS X,
however, it is not, and hence multiple res_query() calls from parallel
threads will compete and return bogus results.
The fix for this is to use res_nquery(), introduced in BIND 8.2, which
takes an explicit state argument. This allows us to manually store the
state thread-locally. If res_nquery() isn’t available, we fall back to
res_query(). It should be available on OS X though. As a data point,
it’s available on Fedora 27.
There’s a slight complication in the fact that OS X requires the state
to be freed using res_ndestroy() rather than res_nclose(). Linux uses
res_nclose().
(See, for example, the NetBSD man page:
https://www.unix.com/man-page/netbsd/3/res_ninit/. The Linux one is
incomplete and not so useful:
http://man7.org/linux/man-pages/man3/resolver.3.html.)
The new code will call res_ninit() once per res_nquery() task. This is
not optimal, but no worse than before — since res_query() was being
called in a worker thread, on Linux, it would implicitly initialise the
thread-local struct __res_state when it was called. We’ve essentially
just made that explicit. In practical terms, this means a
stat("/etc/resolv.conf") call per res_nquery() task.
In future, we could improve this by using an explicit thread pool with
some manually-created worker threads, each of which initialises a struct
__res_state on spawning, and only updates it on receiving
the #GResolver::reload signal.

Some projects use child schemas in an odd way: they link children which
already have their path pre-defined. This causes the child schema (and
its keys) to be printed out twice:
- once because it is, itself, a non-relocatable schema
- once, as a recursion from its parent
We can avoid this by not recursing into child schemas that are
non-relocatable (on the assumption that they will be enumerated
elsewhere).

Commit 281e3010 narrowed the race between GCancellable::cancelled and
GCancellableSource's finalize(), but did not prevent it: there was
nothing to stop cancellation from occurring after the refcount drops
to 0, but before g_source_unref_internal() bumps it back up to 1 to
run finalize().
GCancellable cannot be expected to detect that situation, because the
only way it has to detect last-unref is finalize(), but in that
situation finalize() hasn't happened yet.
Instead of detecting last-unref, relax the precondition a little
to make it detect finalization: priv is only poisoned (set to NULL)
after the finalize() function has been called, so we can assume that
GCancellable has already seen finalize() by then.

* W32 File attributes (which stat() doesn't report); in particular, this allows
symlinks to be correctly identified
* Full, 64-bit time, guaranteed (g_stat() uses 32-bit st_*time on 32-bit Windows)
* Allocated file size (as a W32 replacement for the missing st_blocks)
st_mode remains unchanged (thus, no S_ISLNK), so when these are given back to
glib users (via g_stat(), for example, which is now implemented by calling g_win32_stat_utf8),
this field does not contain anything unexpected.
g_lstat() now calls g_win32_lstat_utf8(), which works on symlinks the way it's supposed to.
Also adds the g_win32_readlink_utf8() function, which behaves like readlink()
(including its inability to return 0-terminated strings and inability to say how large
the output buffer should be; these limitations are purely for compatibility with
existing glib code).
Thus, symlink support should now be much better, although far from being complete.
A new W32-only test in gio/tests/file.c highlights the following features:
* allocated size
* 64-bit time
* unique file IDs

The GAsyncResult documentation didn't specify the context in which the
GAsyncReadyCallback is expected to be invoked. Since asynchronous
operations can be implemented in various ways involving GSources,
threads and coroutines, it is useful to mention what the standard
expections are.
Unfortunately, since this was left undefined for so long, we can only
phrase it as a suggestion, and not as a hard requirement.

Commit 53ed180 improved mtab processing, however, also introduced bug

Fix get_mounts_timestamp() to not use a stat'ed mtime for /proc/ files.
Instead, use mount_poller_time if /proc/ watch is running, or otherwise
return a new generated timestamp to always assume mounts-changed, which
is safer than previous behaviour of always assuming mounts-not-changed
(as mtime never changes for /proc/ files when queried from the same
process).
We say it's safer because allows caches depending on:
g_unix_mounts_get(&time_read)
g_unix_mounts_changed_since()
to drop possibly outdated/duplicated values, as that was the case for the
GIO mounts cache used in gio/glocalfile.c which provides mount info for
g_file_query_filesystem_info() call, as described in below referenced bug.
This fix complements related commit bd9e266e11https://bugzilla.gnome.org/show_bug.cgi?id=787731
Add testcase for function g_file_query_filesystem_info()
reporting outdated info for "filesystem::readonly" attribute
when said attribute was different in a previous mounted
partition in the same device (as GIO maintains a mounts cache
per 'st_dev' stat() member).
To trigger a mount operation, testcase uses program 'bindfs'
instead of 'mount --bind' as bindfs does not require root
privileges. And 'fusermount -u' command is used to unmount said
bindfs mount.
As a reference in Fedora, 'bindfs' is installed from 'bindfs'
package and 'fusermount' from 'fuse' package (this one is installed
by default as being part of 'System Tools' group).
The test creates a directory with a file in it, then mounts it
readonly over another directory (the mountpoint), it then checks
that g_file_query_filesystem_info() for the file in it indeed reports
"filesystem::readonly" as TRUE. Then unmounts and mounts again this
time rw (not readonly), it then checks again if g_file_query_filesystem_info()
is reporting "filesystem::readonly" as TRUE, if that's the case, it
confirms the bug by opening said file in write mode.
Testcase is only added for Unix builds.

I’m unsure what the original reasoning for returning TRUE by default
from supports_dtls was, but it is not backwards-compatible. If a
pre-existing GTlsBackend implementation never implements the
supports_dtls vfunc, the supports_dtls() method will magically return
TRUE rather than FALSE.
Since any backend which does implement DTLS should be implementing the
supports_dtls vfunc (and no DTLS-supporting backends have actually been
merged yet; see bug #697908), it seems safer to make this slight API
break in the name of backwards compatibility than to leave it as
returning TRUE incorrectly.

Language bindings have so far been unable to implement the GListModel
interface because the ::get_item virtual function returns a
non-bindable type (gpointer). The `gpointer` type gets translated into
`void` by G-I meaning that get_item() implementations can't return any
items.
We can set the return type of the get_item() vfunc explicitly to
GObject, which fixes the issue.
This patch also removes the existing (type GObject) annotation on
g_list_model_get_item(), which is necessary because if its return type
matches that of the get_item() vfunc, G-I connects the two and
propagates the 'skip' annotation from one to the other resulting in the
get_item() vfunc being hidden. There's no API break here because the
'skip' annotation makes g_list_model_get_item() invisible to G-I users
anyway.

It's not likely that the runtime of a bound language using the
introspection supports running in a process forked by a foreign
library, so that a closure programmed in that language would work
safely.
Any programming environment supporting that would probably have
its own advanced facilities for process spawning, or be able
to access the GLib spawning APIs via raw C bindings (still
represented in the introspection, (skip) only adds a flag)
and do any low-level preparatory dances as necessary for the
forked runtime.
Note that there are other APIs making use of GSpawnChildSetupFunc,
but they are usable with the closure nullified, and we cannot annotate
the closure parameters away because that would break the annotated API
for bindings; accordingly to bug #738176 comment #3, the current bindings'
users are expected to pass null.

See bug #786456 for a detailed analysis of the situation which can cause
this (in summary, if a g_subprocess_wait_async() call is cancelled on a

The problem was that the GCancellable callback handler was
unconditionally returning a result for the GTask for
g_subprocess_wait_async(), even if that GTask had already returned a
result and the callback was being invoked after the GTask had been
removed from the pending_waits list.
Fix that by checking whether the GTask is still in the pending_waits
list before returning a result for it.

Prevent the situation where errno is set by function A, then function B
is called (which is typically _(), but could be anything else) and it
overwrites errno, then errno is checked by the caller.
errno is a horrific API, and we need to be careful to save its value as
soon as a function call (which might set it) returns. i.e. Follow the
pattern:
int errsv, ret;
ret = some_call_which_might_set_errno ();
errsv = errno;
if (ret < 0)
puts (strerror (errsv));
This patch implements that pattern throughout GLib. There might be a few
places in the test code which still use errno directly. They should be
ported as necessary. It doesn’t modify all the call sites like this:
if (some_call_which_might_set_errno () && errno == ESOMETHING)
since the refactoring involved is probably more harmful than beneficial
there. It does, however, refactor other call sites regardless of whether
they were originally buggy.

Unlike g_application_register, there is no public API to unregister the
GApplication from D-Bus. Therefore, if the GApplication is set up
manually without using g_application_run, then neither can the
GApplicationImpl be destroyed nor can dbus_unregister be called before
destruction.
This is fine as long as no sub-class has implemented dbus_unregister.
If they have, their method method will be called after destruction, and
they should be prepared to deal with the consequences.
As long as there is no public API for unregistering, let's demote the
assertion to a WARNING. Bravehearts who don't use g_application_run
can continue to implement dbus_unregister, but they would have been

When building glib as a subproject, #include's for xdp-dbus.h from xdp-dbus.c
and for gdbus-daemon-generated.h from gdbus-daemon-generated.c were generated as
being prefixed with the subproject prefix, eg
#include "subproject/glib/gio/gdbus-daemon-generated.h".
That failed since the root of the build directory is obviously not part of the
include path when building a subproject.
Passing --output-directory @OUTDIR@ to gdbus-codegen and removing @OUTDIR@ from
--generate-c-code fixes the issue.
meson.source_root() returns the toplevel source directory
of the toplevel project, thus the paths were wrong when using
it. Simply using files() gets us the right path

With meson from git dependencies of dependencies are no
longer added automatically and recursively to the linker
lines. Meaning dependencies that are used have to be
passed directly and explicitly or we'll get linker errors.
Need to fix up some of the tests a little, because the
test binary will not necessarily be run from the current
build sub-directory, and the build directory structure
might not always be a mirror of the source directory
structure, so pass location of glib-mkenums and
glib-compile-scheme and such directly.
This reduces the build-time dependencies of glib to only Python 3,
Meson, and git. Git is also optional if you provide a tarball in
which the subproject directories already exist.
The Python port was done by Jussi Pakkanen on bugzilla:
https://bugzilla.gnome.org/show_bug.cgi?id=779332
This version contains some fixes from that and also changes all
instances of `@` to `\u0040` because Meson does not yet provide a
configure_file() mode that ignores unknown @MACRO@ values.
This is a stub-only library that can be used while building against
MSVC and contains no i18n machinery at all.
The dependencies added indirectly use the libintl.h header, and when
built as a subproject, the header won't be in a path known the
pre-processor.
Don't use it project-wide for building everything. Otherwise
symbols for shared modules won't be exposed, e.g. in the
resourceplugin used by the gio resource unit test.
giomodule test needed symbol visibility pragmas added. This is needed on
Windows anyway, so it's better to do it this way rather than disabling
-fvisibility=hidden for the test modules.
Disable gio tests on Windows, fix .gitignore to not ignore
config.h.meson, and add more things to it.
Rename the library file naming and versioning to match what Autotools
outputs, e.g., libglib-2.0.so.0.5000.2 on Linux, libglib-2.0-0.dll and
glib-2.0-0.dll on Windows with MSVC.
Several more tiny fixes, more executables built and installed, install
pkg-config and m4 files, fix building of gobject tests.

g_build_filename() returns a gchar*, but it was stored in a const gchar*

For historical reasons, the reference dbus-daemon responds to most
method calls on all object paths. However, the canonical path
of the object implementing the o.fd.DBus interface is
/org/freedesktop/DBus, and in some environments (notably AppArmor
with the <abstractions/dbus-session-strict> abstraction) only this
path is allowed.

deprecates all other object paths, and when adding new APIs we will
only make them available on the canonical object path.

Otherwise, we might end up returning TRUE from
g_app_info_launch_default_for_uri but with a set error parameter. This
will lead to confusing results depending on how the caller checks for
errors. Checking error != NULL indicats the call failed but checking the
return value indicates that it succeeded.
There are a few places where commit 18a33f72 replaced valid (nullable)
(optional) annotations with just (optional). That has a different
meaning.
(nullable) (optional) can only be applied to gpointer* parameters, and
means that both the gpointer* and returned gpointer can be NULL. i.e.
The caller can pass in NULL to ignore the return value; and the returned
value can be NULL.
(optional) can be applied to anything* parameters, and means that the
anything* can be NULL. i.e. The caller can pass in NULL to ignore the
return value. The return value cannot be NULL.

We currently assume that the OpenURI portal should be used
unconditionally when running inside a flatpak sandbox. While
the portal is what we usually want, there are exceptions:
Yelp is now included in the GNOME runtime to allow displaying
help without exporting the user documentation, and the sandboxed
app itself may register a scheme handler.
To account for those cases transparently, always try the normal
code path first and only fall back to calling the portal when
that fails.

These calls cause race warnings from tsan, but are not a thread safety
problem, because we can only ever observe single bit changes: all
modifications to the GSource.flags field are done with a lock held; all
reads are of independent fields, so no intermediate state can ever be
observed. This assumes that a non-atomic read will consistently give us
an old value or a new value.
In any case, these g_source_is_destroyed() calls can happen from any
thread, and the state could be changed from another thread immediately
after the call returns; so the checks are pointless. In addition,
calling g_source_set_ready_time() or g_source_destroy() on a destroyed
source is not a problem.

Calling the D-Bus method for the OpenURI portal "protects" the logic from
not ever having the remote method running in case the xdg-desktop-portal
process is not yet running and the caller quits quickly after the call.
This should not be a problem as the method returns immediately (regardless
of the user making a selection), but making it synchronous would prevent
situations where the OpenURI method would never be called because of D-Bus
dropping the message after the caller dies, without explicitly waiting for
a reply.

It was suggested that the project files be moved here as we don't actually
need to go two directory layers from $(srcroot), and would help us to
standardize on things in the future across the board.
When performing the verify and building the error string there were two
possibilities of an infinite loop. The first is the missing twos-complement
to unset the bit in the filtered flags. The second is the lack of handling
G_SUBPROCESS_FLAGS_NONE which can return a valid GFlagsValue (and cannot
unset the bit since the value is zero).
This walks all known values in the GSubprocessFlags type class and check
if they are set. This has the benefit that we don't call needless functions
which walk the same table as well as avoiding mutating values to build
the error string.

GDatagramBased allows connection-oriented and connection-less sockets,
but does not allow stream-based sockets (because it’s datagram-based).
So it supports SCTP and UDP, but not TCP.
Clarify that in the documentation, and people sometimes confuse
connection-oriented with stream-based, due to the prevalence of TCP.
Use mnt_context_get_mtab instead of using mnt_context_get_table(), since
that's the recommended way of accessing mtab/mountinfo information, and

g_socket_listener_add_address() is synchronous; all of the events will

The two known use-cases for autolaunching are:
* X-forwarding: "ssh -Y myhost myapp" resulting in a
session bus on myhost but an X server on the original host
* Legacy desktop environments on OSs without D-Bus integration:
e.g. running a single GNOME or KDE app under fvwm or something,
without a session dbus-daemon being started by either systemd,
gnome-session, or OS integration scripts analogous to Debian's
/etc/X11/Xsession.d/75dbus_dbus-launch
In either case, an X11 DISPLAY is also needed.
"dbus-launch --autolaunch" doesn't do anything useful when unable
to connect to an X11 display; this has been the case since the feature
was added in 2006, and is useful to avoid "split brain" situations in
which two processes that ought to be part of the same session end up
on separate session buses. Since dbus commit 407c111 in 2011,
libdbus hasn't even attempted to run "dbus-launch --autolaunch"
unless getenv("DISPLAY") returns non-null in the parent: this avoids
doing a relatively complicated fork-and-exec that is clearly not
going to lead to success. This commit gives GDBus the same policy.
This change was originally made to work around a race condition in
subprocess spawning (Debian bug #737380, GNOME bug #711090) but
it seems valid in its own right.
In my opinion as D-Bus maintainer, "dbus-launch --autolaunch" should
be considered to be an X11 feature, and any future D-Bus enhancements
(e.g. kdbus) or successors for X11 (e.g. Wayland, Mir) should obtain
a session bus address by other means - either a session manager
such as "systemd --user", gnome-session or Upstart, or a wrapper
for the user session like dbus-run-session(1).

In a vague attempt at ensuring the .stp scripts can be closely
associated with the .so files which they hard-code references to, rename
the scripts so they include the LT version — so that they are the .so
file name plus .stp.
This does not fix the fact that our .stp scripts will not work on
multiarch systems, as they are installed in an architecture-independent
directory (/usr/share/systemtap/tapset). At the moment, it is
recommended that any distribution who package the .stp files should
install them in the architecture-specific subdirectories of this (for
example, /usr/share/systemtap/tapset/x86-64).

This adds a new --c-generate-autocleanup option to gdbus-codegen
which can be used to instruct gdbus-codegen about what autocleanup
definitions to emit.
Doing this unconditionally was found to interfere with existing

The new option takes an argument that can be
none, objects or all; to indicate whether to generate no
autocleanup functions, only do it for object types, or do it
for interface types as well. The default is 'objects', which

The use of past tense in g_task_had_error makes one assume that it

Projects requiring compatibility with GLib < 2.49 can get a

and using a typedef with a distinct name outside the library's

typedef AutoExampleAnimal ExampleAnimal;

g_autoptr (AutoExampleAnimal) animal = NULL;

gdbus-tool prints a hint about the expected arguments to a function call
in case of errors. Unfortunately, it prints this message on all errors.
I've seen this confuse users several times -- they go on tweaking the
arguments trying to get the correct type, even though they had it
correct in the first place.
Let's limit the hint to the case where it was actually invalid arguments
that triggered the problem. Also, adjust the code that prints the
message so that it will also report on the case that no arguments were
expected.
We could possibly get closer to what we want by comparing the list of
expected arguments with the parameter list, as it was parsed from the

When debugging a program or testing a change to an installed version, it
is often useful to be able to replace resources in the program or a
library, without recompiling.
To support this, for debugging and hacking purposes, it's now possible
to define a G_RESOURCE_OVERLAYS environment variable as a
colon-separated list of substitutions to perform when looking up
GResources.
A substitution has the form
"/org/gtk/libgtk=/home/desrt/gtk-overlay"
The part before the '=' is the resource subpath for which the overlay
applies. The part after is a filesystem path which contains files and
subdirectories as you would like to be loaded as resources with the
equivalent names.
In the example above, if an application tried to load a resource with
the resource path '/org/gtk/libgtk/ui/gtkdialog.ui' then GResource would
check the filesystem path '/home/desrt/gtk-overlay/ui/gtkdialog.ui'. If
a file was found there, it would be used instead.
Substitutions must start with a slash, and must not have a trailing
slash before the '='. It is possible to overlay the location of a
single resource with an individual file.
https://bugzilla.gnome.org/show_bug.cgi?id=765668
Replace the hand-written equivalent of this with the call to the
GHashTable built-in version to save a few lines of code.
The GResource code was written a couple of years before this function
existed.
Similarly, replace a set-mode usage of g_hash_table_insert() with a call
to g_hash_table_add().

GContextSpecificGroup has been somewhat broken for a rather long time:
when we remove the last reference on an object held in the group, we try
to clean up the source, but fail to actually remove it from the
mainloop.
We will soon stop emitting signals on the source (due to it having been
removed from the hash table) but any "in flight" signals will still be
delivered on the source, which continues to exist. This is a problem if
the event is being delivered just as the object is being destroyed.
This also means that we leave the source attached to the mainloop
forever (and next time will create a new one)...
This is demonstrated with the GtkAppChooser dialog which writes an
update to the mimeapps.list file just as it is closing, triggering the
app info monitor to fire just as it is being destroyed.
Karl Tomlinson correctly analysed the problem and proposed this fix.

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.

The documentation of g_file_info_copy_into() was misleading. The

that's just a stack variable local to this function. When
klass->get_mount_for_mount_path is called, it's given one const
parameter and the other is unused, so they're unchanged. 'klass'
doesn't seem it could be modified either inside that function.
It doesn't recurse infinitely, but seems to work correctly and pass the

Recent changes to file monitors removed the delay before events were
reported. Among other things, this caused the trash backend of gvfs to
notice trashed files sooner than before.
On noticing trashed files, the backend tries to read the info file to
discover (among other things) the original location of the file.
Unfortunately, g_local_file_trash() does a strange dance when trashing a
file. It does a loop of open(O_EXCL) in order to file an empty filename
in the trash to write an info file to, trashes the file, and only then
writes the contents of the info file. This means that at the time the
file is moved to the trash, the info file is an empty stub.
Change the order so that we write out the actual content of the info
file first. If the actual trash files then we will unlink the info file
anyway.

Previously, GLib returned text/plain for empty files.
This is important because people may want to open empty (eg:
just-created) text files with the text editor.
An unintended side-effect of b6fc1df022
caused GLib to start returning application/octet-stream instead of
text/plain for these files.
This commit is essentially a revert of that commit, with a different
solution: we move the special-case up a bit in the function and
hard-code it to text/plain.
This change does not exactly maintain the old behaviour: previously, a
"fast" lookup would have returned application/octet-stream on an empty
file and now it will return text/plain. I consider this to be an
improvement (since we're returning better data) and don't expect it to
cause problems.

We don't need to run binaries we just built in order to successfully

Since commit b74e2a7, we don't need to run glib-genmarshal when building
GIO; since commit f9eb9eed, all our tests (including the ones that do
need to run binaries we just built) are only built when running "make
check", instead of unconditionally at every build.
This means that we don't need to check for existing, native binaries
when cross-compiling, and fail the configuration step if they are not
found — which also means that you don't need to natively build GLib for
your toolchain, in order to cross-compile GLib.

gvfs commit b358ca "Make sure metadata is always returned by
query_writable_namespaces()" changed the
query_writable_namespaces vfunc to never return NULL, but the error
checking in g_daemon_file_query_writable_namespaces still assumes vfunc
failure implies NULL return value and GError set. This causes a memory
leak as on failure the GError will be set but the vfunc implementation
will have created its own default list so NULL will not be returned, and
the GError will never be cleared.
This commit directly checks if the GError is set to detect failures,
my_error is directly dereferenced in the error block anyway.
This also removes an unneeded call to g_file_attribute_info_new(); as
the vfunc always returns us a non-NULL GFileAttributeInfoList.

These tests clear up a misunderstanding of mine: Monitoring
nonexisting files and directories *does* work with the inotify
implementation, it just has a very long timeout for scanning
for missing locations, so the test needs to take that into
account.
This is meant for opaque, non-POSIX-like backends to indicate that the
URI is not persistent. Applications should look at
G_FILE_ATTRIBUTE_STANDARD_SYMLINK_TARGET for the persistent URI.
Examples of such backends could be a portal for letting sandboxed
applications access the file-system, or a database-backed storage like
Google Drive.
In these cases, the user visible file and folder names are different
from the real identifiers, used by the backend. So, a request to
create google-drive://user@gmail.com/foo/New\ File, would actually
lead to google-drive://user@gmail.com/foo/bar on the server even though
the user visible name is still "New File". Since the server-defined URI
is persistent and sanity-checked by the backend, it is recommended that
applications switch to it as soon as possible. Backends will try to
keep a mapping from "fake" to "real" URIs, but those are only on a
best effort basis. They might not be persistent or have the same
guarantees as the "real" URIs.

g_dbus_method_invocation_return_value(), etc, don't have GError
parameters (which makes sense since they won't usually return errors,
and there's not much you could do if they did), so in the rare case
when something does go wrong, they print a warning.
However, there is at least one situation where the warning is a bad
idea: if you are using private bus connections, and a client connects,
makes a request, and then disconnects before getting the response.
Given that there's nothing the caller can do to prevent this case from
getting hit (since the client might not disconnect until after the
call to g_dbus_method_invocation_return_value() starts) and given that
the server can never actually know for sure that the client has
received the response (it might disconnect after reading the response,
but before processing it), just kill the warning in this case.

Add a new test which checks that atomically replacing a file that
is being monitored by GFileMonitor produced the expected events.
The test can easily be expanded to cover other file monitoring
scenarios.
After the big file monitoring rewrite, we only put the IN_MOVED_FROM event
in the queue for such pairs. It matches INOTIFY_DIR_MASK and thus we call
ip_dispatch_event on it, but that function was filtering it out because
the filename in the 'from' event is the one of the temp file, not the
one we are monitoring. That name is in the 'to' event, so compare it as
well, and let the event passin that case.
There is another instance of this check in glocalfilemonitor.c, which is
corrected here as well.

exit-on-close for a DBus connection is a completely normal thing. On

I've seen several downstream reports of confusion as to what these

that they're so obtuse.
We're also printing them to stderr, when this is not an error.

A signal accumulator can return TRUE to continue signal emission, and
FALSE to stop signal emission. handle-local-options callbacks can return
« return a non-negative option if you have handled your options and
want to exit the process ».
Currently, g_application_handle_local_options_accumulator (the
accumulator for the handle-local-options signal) returns TRUE on
non-negative return value (ie continue signal emission), and returns
FALSE on negative return values (ie when the default option processing
should continue).
This return value seems backward as on >= 0 values, subsequent
handle-local-options callbacks could overwrite the 'exit request' from
the handler, while on < 0 values, the handle-local-options processing
could end up early if several callbacks are listening for this signal.
In particular, the default handler for this signal
(g_application_real_handle_local_options) always returns -1 and will
overwrite >= 0 return values from other handlers.
This commit inverts the check so that signal emission stops early when
one of the handle-local-options callbacks indicates it wants processing
to stop and the process to exit.

This is the right thing to do for the "a session is a user-session"
model implemented in dbus 1.9.14, which is described in

It also resembles sd-bus' behaviour, although sd-bus will only try
kdbus and XDG_RUNTIME_DIR/bus, and never runs dbus-launch.
On systems following the more traditional "a session is a login-session"
model, X_R_D/bus won't exist, so it is harmless to check for it before
falling back to X11 autolaunching. Again, this matches the behaviour
of current libdbus and sd-bus versions.

This matches libdbus' behaviour and the D-Bus Specification, in which

Cancellation of GPollFileMonitor is now handled correctly (in the sense
that no further signals will follow) but let's be extra paranoid and
disconnect our handler anyway, for good measure.

GPollFileMonitor emits CHANGES_DONE_HINT after CHANGED signals, but it
doesn't check to ensure that the file monitor wasn't cancelled before it
does that.
If the original signal caused the monitor to be unreffed, cancelled and
destroyed, we would still end up emitting an extra signal on it.
Avoid that by checking first for cancellation.

In order to maintain a logical stream of events, we need to make sure we
flush and queued change notifications before responding to any requests
for information from clients.
If we don't do this, it's possible that we emit an 'add' event that was
queued at the time of a 'DescribeAll' call _after_ the reply to that
call (which already contained the description of the new action).
In practice, this is not only logically incorrect, but it can also cause
problems. If a change to action 'state' or 'enabled' occurs after the
DescribeAll but before the signal has been dispatched, it will be
ignored because an 'add' signal is already pending. When that add
signal is sent, it will contain the correct data, but the receiver will
ignore it because it already saw the action in the DescribeAll reply.

The code here was returning gtk-directory and similar names as
fallback, with a comment claiming that these are 'builtin gtk'.
But they aren't, anymore, so just return the standard names.
This code used to look at the SCM_CREDENTIALS and ignore every message
not from uid 0. However, when user namespaces are in use this does not
work, as if uid 0 is not mapped you get overflowuid instead. Right now
this means we ignore all messages in such user namespaces and glib
apps hang on startup.
We can't look at pids either, as pid 0 is returned for processes
outside your pid namespace.
Instead the correct approach is to look at the sending sockaddr and
if the port id (nl_pid) is zero, then its from the kernel.

This test originally did not connect to the bus, which meant it was

When test_double_array() was added, environments like the Debian

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.

Make sure error handling on repeated <summary> and <description> is
being done properly, not resulting in glib-compile-schemas throwing a
critical.
https://bugzilla.gnome.org/show_bug.cgi?id=747542
Fix a couple of issues in error handling in glib-compile-schemas.
The first problem is that, in case of repeated <summary> or
<description> tags we were still allocating a GString which was never
being freed (due to the throwing of the error resulting in immediate
termination of the parse).
The second problem is that if the repeated <summary> tag also had
attributes, we would attempt to set the GError twice.
https://bugzilla.gnome.org/show_bug.cgi?id=747542
Bug 747209 introduced an error when multiple <summary> or <description>
tags are found for a single key in a GSettings schema. This check
should have been present from the start, but it was left out because the
schema compiler doesn't include these items in the cache file. Even
still -- part of the schema compiler's job is validation, and it should
be enforcing proper syntax here.
Repeated <summary> and <description> tags are a semi-common problem when
intltool has been misconfigured in the build system of a package, but
it's possible to imagine mistakes being made by hand as well.
The idea is that these problems would be caught during the build of a
package and maintainers would be forced to fix their build systems.
An unintended side-effect of this change, however, is that the schema
compiler started ignoring already-installed schemas that contained these
problems, when rebuilding the cache. This means that the installation
of _any_ application would cause the regeneration of the entire cache,
with these already-installed applications being excluded. Without the
schema in the cache, the application would crash on next startup.
The validation check in the gsettings m4 macro passes --strict to the
compiler, which is not used when rebuilding the cache after
installation. Pass this flag down into the parser and only throw the
error in case --strict was given. This will result in the (desired)
build failure without also causing already-installed apps to stop
functioning.
This means that we will not get even a warning about the invalid schema
file in the already-installed case, but that's fine. There is no sense
spamming the user with these messages when they are already quite fatal
for the developer at build time.

Add support for copying session data between client connections.
This is needed for implementing FTP over SSL. Most servers use a separate
session for each control connection and enforce sharing of each control
connection's session between the related data connection.
Copying session data between two connections is needed for two reasons:
1) The data connection runs on a separate port and so has a different
server_identity which means it would not normally share the session with
the control connection using the session caching currently implemented.
2) It is typical to have multiple control connections, each of which
uses a different session with the same server_identity, so only one of
these sessions gets stored in the cache. If a data connection is opened,
(ignoring the port issue) it may try and reuse the wrong control
connection's session, and fail.
This operation is conceptually the same as OpenSSL's SSL_copy_session_id
operation.

GTask used a 10-thread thread pool for g_task_run_in_thread() /
g_task_run_in_thread_sync(), but this ran into problems when task
threads blocked waiting for another g_task_run_in_thread_sync()
operation to complete. Previously there was a workaround for this, by
bumping up the thread limit when that case was detected, but deadlocks
could still happen if there were non-GTask threads involved. (Eg, task
A sends a message to thread X and waits for a response, but thread X
needs to complete task B in a thread before returning the response to
task A.)
So, allow GTask's thread pool to be expanded dynamically, by watching
it from the glib worker thread, and growing it (at an
exponentially-decreasing rate) if too much time passes without any
tasks completing. This should solve the deadlocking problems without
causing sudden breakage in apps that assume they can queue huge
numbers of tasks at once without consequences.

Fix that.
We declare the typedefs for GListModel and GListStore in giotypes.h, as
a matter of convention. This is not actually required, since the
typedef is emitted as part of the G_DECLARE_* macros.
The giotypes.h approach is only used to avoid cyclic dependencies
between headers, which is not a problem in this case.
Type redefinition is a C11 feature, and although it was around in some
compilers before then, gcc 4.2.1 (from 2007) is apparently still in wide
use, being the default compiler for OpenBSD.
Eventually, we will probably hit a case where we actually need to
redefine a type, but since we're not there yet, let's back off a bit.
This WIP patch moves the Windows Directory Monitoring code to the new
GLocalFileMonitor mechanism, and adds file monitoring in the process.
Progress from previous patch:
-File renames are now properly supported, but G_FILE_MONITOR_EVENT_MOVED_IN
and G_FILE_MONITOR_EVENT_MOVED_OUT needs to be investigated, as
ReadDirectoryChangesW() seems to send FILE_ACTION_REMOVED when a file is
moved out of a directory.
-Events are handled for both the long and short (8.3) variants of the
filenames, and files monitored will report changes when it is changed
via its short or long filenames.
Things to be done:
-Perhaps find out about attribute changes in files in a monitored
directory; if a file is monitored, attribute changes are correctly
handled.
-Investigate on G_FILE_MONITOR_EVENT_MOVED_OUT,
G_FILE_MONITOR_EVENT_MOVED_IN, G_FILE_MONITOR_EVENT_PRE_UNMOUNT,
G_FILE_MONITOR_EVENT_UNMOUNTED.
-Investigate on the "boredom" algoritm, and see how we can do it on

Completely rewrite the FAM file monitor. Major changes:
- now runs in the worker thread
- dispatches events in a threadsafe way via GFileMonitorSource
- uses unix fd source instead of a GIOChannel
- is now simple enough to fit into one short file
This is the bare minimal effort. This seems not to crash immediately,
but it definitely needs some better testing.
The backend is not in good shape. It could use some serious work.
Use the "interesting" value from g_file_monitor_source_handle_event() to
decide if we're currently being flooded by a stream of boring events.
The main case here is when one or more files is being written to and the
change events are all being rate-limited in the GFileMonitor frontends.
In that case, we become "bored" with the event stream and add a backoff
timeout. In the case that it is exactly one large file being written
(which is the common case) then leaving the event in the queue also lets
the kernel perform merging on it, so when we wake up, we will only see
the one event. Even in the case that the kernel is unable to perform
merging, the context switch overhead will be vastly reduced.
In testing, this cuts down on the number of wake ups during a large file
copy, by a couple orders of magnitude (ie: less than 1% of the number of
wake ups).
Return an "interesting" boolean from the event handler function on
GFileMonitorSource.
An event was "interesting" if it will result in a signal actually being
dispatched to the user. It is "uninteresting" if it only hit an
already-dirty rate limiter.
We will use this information to do some backing off in the backends when
faced with a flood of uninteresting events.
We generally assume that an IN_CREATE event is the start of a series of
events in which another process is doing this:
fd = creat (...) -> IN_CREATE
write (fd, ..) -> IN_MODIFY
write (fd, ..) -> IN_MODIFY
close (fd) -> IN_CLOSE_WRITE
and as such, we use the CHANGES_DONE_HINT event after CREATED in order
to show when this sequence of events has completed (ie: when we receive
IN_CLOSE_WRITE when the user closes the file).
Renaming a file into place is handled by IN_MOVED_FROM so we don't have
to worry about that.
There are many other cases, however, where a new file 'appears' in a
directory in its completed form already, and the kernel reports
IN_CREATE. Examples include mkdir, mknod, and the creation of
hardlinks. In these cases, there is no corresponding IN_CLOSE_WRITE
event and the CHANGES_DONE_HINT will have to be emitted by an arbitrary
timeout.
Try to detect some of these cases and report CHANGES_DONE_HINT
immediately.
This is not perfect. There are some cases that will not be reliably
detected. An example is if the user makes a hardlink and then
immediately deletes the original (before we can stat the new file).
Another example is if the user creates a file with O_TMPFILE. In both
of these cases, CHANGES_DONE_HINT will still eventually be delivered via
the timeout.
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.
Remove the hardwired 1 second event queue logic from inotify-kernel and
replace it with something vastly less complicated.
Events are now reported as soon as is possible instead of after a
delay.
We still must delay IN_MOVED_FROM events in order to look for the
matching IN_MOVED_TO events, and since we want to report events in order
this means that events behind those events can also be delayed. We
limit ourselves, however:
- no more than 100 events can be delayed at a time
- no event can be delayed by more than 10ms

Add a new internal constructor for GLocalFile (which itself is private).
This new constructor allows creating a GLocalFile from a dirname and a
basename, assuming that the dirname is already in canonical form and the
basename is a regular basename.
This will be used for creating GLocalFile instances from the file
monitoring code (for signal emissions).
For all of the effort spent ensuring that this algorithm would be
correctly threadsafe, I messed up the order of operations within a
single thread when porting to the new approach.
Fix that up.
Also: fix some overzealous asserting in the testcases. Since shutdown
is now lazy, we can never surely say !is_running at any particular point
in time.
This can be used to query whether the task has completed, in the sense
that it has had a result set on it, and has already – or will soon –
invoke its callback function.
Notifications for this property are emitted immediately after the task’s
main callback, in the same main context as that callback. This allows
for multiple bits of code to listen for completion of the GTask, which
opens the door for blocking on cancellation of the GTask and improved
handling of ‘pending’ behaviour.

arrive while waiting for a start. Attempting to deal with start and
stop in an asymmetric way could have lead to other weird situations,

g_application_bind_busy_property() had the restriction that only one

Add an implementation of non-thread-emulated async close of a GIOStream
if either of the underlying stream objects support it.
This prevents us from calling close() functions from another thread on
an object that may not be expecting that. It also allows us to skip the

delayed_close_free() calls g_object_unref() on a variable that is

GApplication set the prgname to the application's id when it was running
in service mode. This broke with the addition of new --app-id option,
because g_set_prgname() was called before parsing the options. Calling
it after option parsing doesn't work, because GOptionContext sets
prgname to argv[0] unconditionally.
Instead of changing the semantics of GOptionContext, simply remove this
functionality from GApplication. It is very unusual to have the prgname
set to the app id instead of the binary's name and might confuse people
when looking at logs etc.
When overriding local_command_line() from a subclass,
g_option_context_parse() might never be invokded. Thus, continue setting
the prgname to argv[0] in GApplication.

Make sure that we only match the _get_type() function name by
restricting the regexp to matching [A-Za-z0-9_]. We were matching on .*
before which means that if we had two _get_type() functions appearing on

the default rule of '*' being greedy).
This affected G_DECLARE_*_TYPE which puts several uses of _get_type()

When implementing blocking operations on top of
nonblocking sockets we should always first try to
perform the operation and then if needed handle
EAGAIN and wait with g_socket_wait_condition.
This is an optimization since we avoid calling
wait condition when it is not needed, but most
importantly this fixes hangs on win32 where some
events (in particular FD_WRITE) are only emitted
after the operation fails with EWOULDBLOCK.

Add a unit test that checks g_socket_new_from_fd by creating
a gsocket, obtaining its fd, duplicating the fd and then creating
a gsocket from the new fd. This shows a hang on win32 since the

because we wait for the condition without first trying to write
and windows signals the condition only after a EWOULDBLOCK error.

Fix two problems:
1) If g_socket_service_stop is called before the accept call is requeued,
then the reference count won't decrease and this code will hang forever:
while (G_OBJECT (service)->ref_count == ref_count)
g_main_context_iteration (NULL, TRUE);
2) Sometimes the testcase fails (maybe 1 in 200 times for me):
GLib-GIO:ERROR:socket-listener.c:73:connection_cb: assertion failed
(G_OBJECT (service)->ref_count == 2): (3 == 2)
Aborted (core dumped)
The problem is that depending on ordering, cancellation of the async
listener can require further main context iterations before it releases
the reference on the socket service. Furthermore, in some cases, it
requires at least one iteration.

Add G_IO_ERROR_CONNECTION_CLOSED as an alias for
G_IO_ERROR_BROKEN_PIPE, and also return it on ECONNRESET.
It doesn't really make sense to try to distinguish EPIPE and
ECONNRESET at the GLib level, since the exact choice of which error
gets returned in what conditions depends on the OS. Given that, we
ought to map the two errors to the same value, and since we're already
mapping EPIPE to G_IO_ERROR_BROKEN_PIPE, we need to map ECONNRESET to
that too. But the existing name doesn't really make sense for sockets,
so we add a new name.

This is a convenience method for creating a GNetworkAddress which is
guaranteed to return IPv4 and IPv6 loopback addresses. The program
cannot guarantee that 'localhost' will resolve to both types of
address, so programs which wish to connect to a local service over
either IPv4 or IPv6 must currently manually create an IPv4 and another
IPv6 socket, and detect which of the two are working. This new API
allows the existing GSocketConnectable machinery to be used to
automate that.

g_settings_has_signal_handlers() checks whether any of the signals has
pending handlers. However, g_signal_has_handler_pending() matches on
exact detail, even when passing 0. Subscribing to one of GSettings'
signals with a detail will fail this check and never connect to the
backend.
Fix this by calling has_handler_pending() with the key as detail as
well.

Add a GSocketListener test program. Currently the only test is a
regression test for bug 712570 (based on a standalone bug reproducer
provided by Ross Lagerwall).
If all users of a GThreadedSocketService release their references to the
service while a connection thread is running, the thread function will
release the last reference to the service which causes the finalize to
deadlock waiting for all threads to finish (because it's called from the
thread function).
To fix this, don't wait for all threads to finish in the service's
finalize method. Since the threads hold a reference to the service,
finalize should only be called when all threads are finished running (or
have unrefed the service and are about to finish).

If SSL 3.0 has been disabled (at the host, application, or library
level), then the "use-ssl3" property becomes a "fail-immediately"
property.
Despite the name, the point of the property wasn't really specifically
to use SSL 3.0; it was to allow fallback when talking to broken
servers that do SSL/TLS negotiation incorrectly and break when they
see unexpectedly-high version numbers. So if we can't fall back to SSL
3.0, then the "use-ssl3" property should fall back to TLS 1.0 instead
(since there are hosts that will reject a TLS 1.2 handshake, but
accept a TLS 1.0 one).
glib-networking is being updated to implement that behavior, so update
the documentation here.
https://bugzilla.gnome.org/show_bug.cgi?id=738633
In commit 8ff5668, we are subscribing the GSettings backend later, but this
meant that we need to initialize cache_lock earlier, as we might try to
use that lock before a change notification is issued to subscribe the
backend, which would then cause an access violation if we are trying to
read GSettings values, as that lock is used to access the Windows Registry.
Initialize cache_lock once we initialize the GSettings Registry backend,
and delete it upon finalize, so that g_settings_read_from_backend() can
proceed normally, even if the GSettings backend is not yet subscribed.

GSettings objects begin watching for changes as soon as they are created
in order that they can emit the "changed" signal.
In the case of dconf, if we want to be able to emit the changed signal,
we need to go on the bus and add some match rules. This requires
creating the dconf helper thread and also requires initialising GDBus
(which creates another thread).
Some users of GSettings are never interested in the "changed" signal.
One of these users is the glib-networking code that gets run every time
a new network connection is created.
Some users are reporting that they are annoyed that simply establishing
a network connection would spawn two extra threads and create a D-Bus
connection.
In order to avoid doing unnecessary work for these simple uses, delay
the subscription until we know that we will actually need to do it.
We do this in a simple way, using a simple argument: in order for the
user to care that a value changed then they must have:
1) watched for a change signal; and then
2) actually read a value
If the user didn't actually read a value then they cannot possibly be
interested in if the value changed or not (since they never knew the old
value to begin with and therefore would be unable to observe that it
ever changed, since they have nothing to compare the new value with).
This really is a behaviour change, however, and it does impact at least
one user: the 'monitor' functionality of the GSettings commandline tool,
which is interested in reporting changes without ever having known the
original values. We add a workaround to the commandline tool in order
to ensure that it continues to function properly.
It's also possible to argue that it is completely valid to have read a
value and _then_ established a change signal connection under the
(correct) assumption that it would not have been possible to miss a
change signal by virtue of not having returned to the mainloop.
Although this argument is true, this pattern is extremely non-idiomatic,
and the problem is easily avoided by doing things in the usual order.
We never really talked about change notification in the overview
documentation for GSettings, so it seems like now is a good time to add
some discussion, including the new rules for when one can expect change
signals to be emitted.

There are two consistent interpretations that could be taken for memory
handling of the 'invocation' parameter passed to the method_call() virtual
function of GDBusInterfaceVTable
- A reference is passed (transfer full) to the method_call() virtual function,
and that reference is then passed (transfer full) to the return_value/error
functions on GDBusMethodInvocation.
- An internal reference is retained from the point where method_call() is called
until the return_value/error function is called.
Since the return_value/error functions were already marked (transfer full),
we use the first interpretation, annotate the invocation parameter of
method call as (transfer full) and describe this in the documentation, along
with the idea that you are always supposed to call one of the return_value/error
functions.

da053e34 broke the tls-certificates test by requiring the backend to

Add an asynchronous version of _read_all().
This API is not fully consistent with the normal expectations of a
non-asynchronous version. Consistency between the sync and async version is
probably more important.
The API will still bind correctly, but access to all functionality will
not be available: specifically, in the case of an error, higher level
languages will be unable to determine how many bytes were successfully
read before the error. Most users will probably not want to use this
information anyway, so this is OK -- and if they do need the
information, then they can just write the loop for themselves.

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.
This patch changes the behavior of the following functions:
g_tls_certificate_new_from_pem
g_tls_certificate_new_from_file
g_tls_certificate_new_from_files
If more than one certificate is found it will try to load the chain.
It is assumed that the chain will be in the right order (top-level
certificate will be the last one in the file). If the chain cannot be
verified, the first certificate in the file will be returned as before.

g_thread_pool_push() only returns an error if it fails to spawn a new
thread. However, it unconditionally adds the task to its worker queue,
so:
• if _any_ threads exist in the pool, the task will eventually be
handled; and
• if _no_ threads exist in the pool, the task will be handled if one
is eventually successfully spawned.
If no more threads are ever spawned, the process probably has bigger
problems than a single GTask which is taking forever to complete.

For the GPtrArray example, several variables declared on the same line
is harder to read and to work with (to move, remove or comment a single
variable declaration).
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.
If a g_socket_client_connect_async() operation is cancelled between the
CONNECTING and CONNECTED events (i.e. while in the
g_socket_connection_connect_async() call), the code in
g_socket_client_connected_callback() would previously unconditionally
loop round and try the next socket address from the address enumerator
(by calling enumerator_next_async()). This would correctly handle the
cancellation and return from the overall task — but not before emitting
a spurious RESOLVING event.
Avoid emitting the spurious RESOLVING event by explicitly handling
cancellation at the beginning of g_socket_client_connected_callback().

A critical message is printed when a parameter of g_file_equal() is not

GResolver doesn't do full validation of its inputs, so in some of

G_RESOLVER_ERROR_NOT_FOUND is because the junk string was getting

there's no network on the machine then we'd get
G_RESOLVER_ERROR_INTERNAL instead in that case.
Windows does not like g_unlink() to be called on files whose file
descriptor is still open, so doing that would cause a permission
denied error. Since the fd is not used in that function after

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.

GDummyTlsConnection didn't implement the "interaction" property,
meaning you'd get warnings if you tried to set it while creating a
GTlsConnection when using the dummy backend. (Of course, trying to
create the GTlsConnection will fail anyway, but it ought to fail
without hitting any g_warnings.)
It was previously possible for GThreadedResolver to return an empty list
and no error in response to a g_resolver_lookup_by_name() call, if it
happened that all the addresses returned by getaddrinfo() could not be
converted from native addresses to GSocketAddresses.
Fix that by setting a G_RESOLVER_ERROR_NOT_FOUND if the returned list is
empty.
https://bugzilla.gnome.org/show_bug.cgi?id=728776
The documentation previously wasn’t clear about whether the GResolver
methods could return an empty list and no error. On balance, this seems
like a bad idea, and GResolver should commit to always return a
non-empty list, or an error (which should be G_RESOLVER_ERROR_NOT_FOUND
if the list would otherwise be empty).

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).

In the event that a GSettings object is being destroyed just as a change
signal is being delivered, the destroying thread will race with the
dconf worker thread for acquiring the lock on the GSettingsBackend.
If the signalling thread gets there first then the destroying thread
will block on the lock. The signalling thread adds a reference to the
GSettings object that is being destroyed and releases the lock. The
idea is that this should prevent the GSettings object from being
destroyed and thus maintain its entry in the list. Unfortunately, the
weak reference notify function is already running and as soon as we
release the lock, the list entry is removed.
The signalling thread crashes.
This bug is indicative of a serious problem encountered in many
situations where GObject instances are touched from multiple threads.
Ideally, we will move to a place where g_object_ref() is not called at
all on the GSettings object from the dconf worker thread and instead, a
dispatch will be done without holding a reference (similar to how
GAppInfoMonitor presently works). This would also prevent the
unfortunate case of someone dropping what they assume to be the last
reference on a GSettings object, only to have an already-pending signal
delivered once they return to the mainloop, crashing their program.
Making this change for GSettings (with multiple instances per thread,
the possibility of multiple backends and each instance being interested
in different events) is going to be extremely non-trivial, so it's not a
change that makes sense at this point in the cycle.
For now, we can do a relatively small and isolated tweak so that we
never access the list except under a lock. We still perform the bad
pattern of acquiring a ref in a foreign thread which means that we still
risk delivering a signal to a GSettings object that the user has assumed
is dead (unless they explicitly disconnect their signal handler). This
is a problem that we already had, however.
https://bugzilla.gnome.org/show_bug.cgi?id=710367
Change the order of the arguments on the (internal) keys_changed callback in
GSettingsListenerVTable.
This means that all functions in the table now fit the following signature:
void (* f) (GObject *target,
GSettingsBackend *backend,
const gchar *name_or_path,
gpointer origin_tag,
const gchar * const *names);
allowing the possibility of arguments ignored at the end.
This allows us to simplify our dispatch-to-thread code in GSettingsBackend,
making it a bit less generic.
So far, this should be a straight refactor.

On the splice for stdout or stderr completing, GSubprocess calls
_slice_finish() to collect the result.
We assume that a zero return value here means failure, but in fact this
function returns a gssize -- the number of bytes transferred, or -1 for

This causes GSubprocess to mistakenly think that it has an error when it
actually just has an empty buffer (as would be the case when collecting
stderr from a successful command).

In addition to the standard "192.168.1.1" format, there are numerous

except in phishing attempts. GLib wasn't supposed to be accepting
these addresses (neither g_hostname_is_ip_address() nor
g_inet_address_new_from_string() recognizes them), but getaddrinfo()
accepts them, and so the parts of gio that use getaddrinfo()
accidentally did accept those formats.

Our check for inotify_init1() being defined is broken. We happily
declare that inotify is supported, even if the check fails.
This was originally intended to check for inotify_init1 in the libc so
that we could fall back to inotify_init if it was not yet defined.
FreeBSD has a libinotify that emulates the inotify API via kqueue. It
installs a <sys/inotify.h> header and requires linking to -linotify. We
don't want to falsely detect working inotify in this case.
Treat the lack of inotify_init1() in the libc as a lack of inotify
support. This requires only a new libc -- we still support old kernels:
in the case that inotify1_init() fails, we fall back to inotify_init().

local_command_line.
As a special feature, you can have a %NULL @arg_data in a GOptionEntry

dictionary is available for inspection and modification by the
"handle-local-options" signal and can be forwarded to the primary
instance in cases of command line invocation (where it can be fetched
using g_application_command_line_get_options()).

If the action is stateful and the user doesn't have their own activate handler
then do some reasonable things for ourselves.
After a lot of experience using stateful GSimpleAction it turns out that
people almost always end up using it in the same ways:
A boolean-typed stateful action with no parameter is most likely going
to want to be toggled. Any other type of action that has the parameter
type equal to the state type probably intends for activation to
represent a request to change the state.
This patch implements those two cases. This will let people stop
writing their own trivial handlers over and over.

Clarify in the documentation that the commandline arguments passed
around by GApplication (to local_command_line and returned via
g_application_command_line_get_arguments()) are in the GLib filename
encoding (ie: UTF-8) on Windows, not the system code page.
Fix the mismatch that would result from having argv passed to
g_application_run() in main() on Windows (where it is in the system
code page) by ignoring argc/argv on Windows and calling
g_win32_get_command_line() for ourselves. Document this.
This might be a slight API break on Windows: we documented that it was
possible to call g_application_run() with arguments other than argc/argv
and now doing that will result in those arguments being ignored. It has
always been recommended practice to only call g_application_run() from
main() directly, however, and all of our code examples have shown only
this. We will see if this causes any issues and consider reevaluating

The default local_command_line handler has a fast return path for the
case that we handle the commandline by forwarding it to the primary
instance, but this doesn't account for the fact that we may want to
become a service.
Allow for this by making sure we don't take the fast path of the service
flag is set.
Add a --gapplication-service switch to the default implementation of
local_command_line. This name is unlikely to clash with any option used

When a normal application (neither service nor launcher) is launched with
exactly this one argument, G_APPLICATION_IS_SERVICE will be set.
The idea is that people will write their D-Bus service file with

When replacing a version of goa-daemon (from gnome-online-accounts)
by a newer version with some added interfaces, evolution-data-server

definition for this new interface.
Work-around this by returning earlier from the _notify() implementation,
rather than accessing invalid memory.

This function turns a varargs argument list into a string array,
but forgets to NULL-terminate it. This function was not covered
by unit tests...so it was broken.
The test reveals that there's something fishy with this monitor.
One has to call g_app_info_get_all() for it to start working,
and then it only works once.
The previous patch to simplify the GSettings commandline tool by making
more use of global variables went a bit too far and broke 'gsettings
monitor' when used without a specific key.
Fix that up again.
The static analyser (correctly) considers a type check to fail if the
variable is NULL. In this case, the address must be non-NULL as no error
was thrown by g_socket_connection_get_remote_address(), but the static
analyser doesn’t know this.
Add a non-NULL assertion anyway, both to shut the analyser up, and
because it’s good extra testing.

These prevent some false positives from the static analyser which are
caused by it not inspecting the invariants of

If the initial part of the header (‘MIME-TreeMagic’) is valid, but the
following line does not start with ‘[’ (i.e. is not a valid section
line), insert_matchlet() will be called with a NULL match pointer, and
will crash with a NULL pointer dereference.
Fix this by bailing out if a valid section line isn’t encountered before
the first insert_matchlet() call (i.e. between the header line and the
first data line).
Note that this has not been tested against a real treemagic file; the
fix is purely theoretical.

The static analyser will check dynamic type assertions and assume that
if they fail, the variable can either have the wrong type, or be NULL

In Windows development environments that have it, <unistd.h> is mostly
just a wrapper around several other native headers (in particular,
<io.h>, which contains read(), close(), etc, and <process.h>, which
contains getpid()). But given that some Windows dev environments don't
have <unistd.h>, everything that uses those functions on Windows
already needed to include the correct Windows header as well, and so
there is never any point to including <unistd.h> on Windows.
Also, remove some <unistd.h> includes (and a few others) that were
unnecessary even on unix.

Assume unix platforms support the original POSIX.1 standard.
Specifically, assume that if G_OS_UNIX, then we have chown(),
getcwd(), getgrgid(), getpwuid(), link(), <grp.h>, <pwd.h>,
<sys/types.h>, <sys/uio.h>, <sys/wait.h>, and <unistd.h>.
Additionally, since all versions of Windows that we care about also
have <sys/types.h>, we can remove HAVE_SYS_TYPES_H checks everywhere.
Also remove one include of <sys/times.h>, and the corresponding
configure check, since the include is not currently needed (and may
always have just been a typo for <sys/time.h>).
https://bugzilla.gnome.org/show_bug.cgi?id=710519
Assume all supported platforms implement C90, and therefore they
(correctly) implement atexit(), memmove(), setlocale(), strerror(),

(Also remove the configure check testing that "do ... while (0)" works
correctly; the non-do/while-based version of G_STMT_START and
G_STMT_END was removed years ago, but the check remained. Also, remove
some checks that configure.ac claimed were needed for libcharset, but
aren't actually used.)
Note that removing the g_memmove() function is not an ABI break even
on systems where g_memmove() was previously not a macro, because it
was never marked GLIB_AVAILABLE_IN_ALL or listed in glib.symbols, so
it would have been glib-internal since 2004.

Just copy the schemas to the builddir and compile them in place instead
of trying to mess around with creating the compiled file in a different

GSettings expects the usual situation of having the .xml files present

We need to check for the correct line endings on Windows (\r\n) for the

The first time this function is called we load all of the keyfiles in

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.

We need to use g_content_type_get_mime_type() to look up the mime type of
the file from the registry on the content type that was acquired on
Windows, as g_file_info_get_content_type() does not acquire the
file mime type (unlike on *NIX).
g_content_type_get_mime_type() on *NIX is more or less an no-op as it
simply returns the g_strdup()-ed version of the passed-in content type.
This will enable the resources test to pass on Windows.

g_object_set() allowed us to bypass the usual checks that the state

Add an API to read the summary and description from the .xml schema
files.
This will be used by dconf-editor and gnome-tweak-tool.
This API is a bit heavy -- it parses the XML and builds a table. It
also loads gettext domains for translation. It only does these things
if it is used, however, so it will not impact normal applications.
We store the summary/description in a pair of hash tables on the schema
source (which we have a backref to as of a few commits ago). We can't
use a global table because people might want to request summary and
description from non-default sources. We don't want to use per-schema
tables because we'd have to reparse the directory every time (since we
cannot guess which file a schema may have been in).

This code was added for use by the G_FILE_ATTRIBUTE_THUMBNAIL_IS_VALID
file attribute, but may end up being used elsewhere (e.g. in GVfs) as well.
As it’s dealing with untrusted external files, and the non-trivial PNG file
format, this commit adds several test cases to cover valid and invalid PNG
files.
The security model for the thumbnail verification code is that the user’s
cache directory is untrusted, and potentially any PNG file which is passed
to the verifier has been manipulated arbitrarily by an attacker.
This is a follow-up to commit fe7069749f.
https://bugzilla.gnome.org/show_bug.cgi?id=709898
This indicates whether the thumbnail (given by G_FILE_ATTRIBUTE_THUMBNAIL_PATH)
is valid — i.e. to represent the file in its current state. If
G_FILE_ATTRIBUTE_THUMBNAIL_IS_VALID is FALSE (for a normal _or_ failed
thumbnail) it means the file has changed since the thumbnail was generated, and
the thumbnail is out of date.
Part of checking thumbnail validity (by the spec) involves parsing
headers out of the thumbnail .png so we include some (small) code to do
that in a separate file. We will likely want to copy this code to gvfs
to do the same for GVfsFile.
Heavily based on a patch from Philip Withnall <philip.withnall@collabora.co.uk>
who suggested the feature and designed the API.

It is our intention that memory output streams should operate in two
distinct modes, depending on if a realloc function was provided or not.
In the case that we have a realloc function (resizable mode), we want
the stream to behave as if it were a file that started out empty. In
the case that we don't have a realloc function (fixed-sized mode), we
want the stream to behave as a block device would.
To this end, we introduce two changes in functionality:
- seeking to SEEK_END on a resizable stream will now seek to the end of
the valid data region, not to the end of the allocated memory (which
is really just an implementation detail)
- seeks past the end of the allocated memory size are now permitted,
but only on resizable streams. The next write will grow the buffer
(inserting zeros between).
Some tweaks to testcases were required in order not to break the build,
which indicates that this is an API break, but it seems unlikely that
anyone will be effected by these changes 'in the real world'.
Updates to documentation and further testcases are in following commits.
Based on a patch from Maciej Piechotka <uzytkownik2@gmail.com>.

Introduce the concept of "fixed" vs. "resizable" streams and document
how g_seekable_seek() works for each case.
