Bug #786580 triggered this warning to show up in the appinfo tests if
run on a machine where no terminal except xterm is installed (for
example, a build machine). Since we didn’t warn before if xterm but no
other terminals were installed, it seems reasonable to downgrade the
warning to a debug message.

That event is deprecated, and the kqueue backend can’t provide enough

Quite disappointed in the kqueue documentation for this: I cannot find a

In the vast majority of cases, we can avoid temporary
allocations for paths in g_resources_enumerate_children().
In the case we need to add a suffix "/", we can usually just
build the path on the stack. In other cases, we can completely
avoid the strdup, which appears to only have been added for
readability. If the path is really long, we fallback to doing
what we did before, and use g_strconcat().
In the case of Builder, this saved 5.3mb of temporary
allocations in the process of showing the first application
window.
https://bugzilla.gnome.org/show_bug.cgi?id=790275
Previously, the path canonicalization for resources had liberal use of
strlen() and memmove() while walking through the path. This patch avoids
any secondary strlen() and removes all use of memmove().
A single allocation is created up front as we should only ever need one
additional byte more than then length of the incoming path string.
To keep the implementation readable, the mechanics are kept in external
functions. memrchr() was not used due to its lack of portability.
This is faster in every test case I've tested. Paths that contain
relative ../ have the most speedup.

This commit adds new W32-only functions to gstdio.c,
and a new header file, gstdioprivate.h.
These functions are:
g_win32_stat_utf8()
g_win32_lstat_utf8()
g_win32_fstat()
and they fill a private structure, GWin32PrivateStat,
which has all the fields that normal stat has, as well as some
extras.
These functions are then used throughout glib and gio to get better
data about the system. Specifically:
* Full, 64-bit size, guaranteed (g_stat() is forced to use 32-bit st_size)
* Full, 64-bit file identifier (st_ino is 0 when normal stat() is used, and still is)
* 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

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

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.

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.

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.

The /etc/mtab file is still used by some distributions (e.g. Slackware),
so it has to be monitored instead of /proc/self/mountinfo in order to
avoid races between g_unix_mounts_get and "mounts-changed" signal. The
util-linux is built with --enable-libmount-support-mtab in that case and
mnt_has_regular_mtab is used for checks. Let's use mnt_has_regular_mtab
also to determine which file to monitor.

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
adequately notified.
This reverts commit c1ae1170fa.
https://bugzilla.gnome.org/show_bug.cgi?id=725950
Invoking the dbus_unregister virtual method during destruction is
problematic. It would happen after a sub-class has dropped its
references to its instance objects, and it is surprising to be asked to
unexport exported D-Bus objects after that.
This problem was masked as a side-effect of commit 21b1c390a3.
Let's ensure that it doesn't regress by asserting that dbus_unregister
has happened before destruction.
Based on a patch by Giovanni Campagna.

When using the Freedesktop backend for GNotification, it seems like a
better idea to map G_NOTIFICATION_PRIORITY_HIGH to NOTIFY_URGENCY_NORMAL
(instead of NOTIFY_URGENCY_CRITICAL) provided that the difference
between GNotification's NORMAL and HIGH priorities is minor.

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.
Changes to gdbus-codegen to support out-of-tree builds without
environment variables set (which you can't in Meson). We now add the
build directory to the Python module search path.
g_build_filename() returns a gchar*, but it was stored in a const gchar*
and then g_free()d, which is wrong and led to a warning about the const
qualifier being cast away.
The g_file_copy() documentation didn't mention if
G_FILE_COPY_ALL_METADATA was applicable or not, and users were led to
call g_file_copy_attributes() to specify it after the g_file_copy()
call, unless they checked the source (been there, done that).

FreeBSD, DragonflyBSD and NetBSD support O_NOFOLLOW, but they use error
numbers that are different from what POSIX standard specifies. They are
not going to change the behavior, and existing programs on these systems
already take advantage of this difference. To support them, we have to
add a check in GIO to use different error numbers on these systems.

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.
https://bugs.freedesktop.org/show_bug.cgi?id=101256 officially
deprecates all other object paths, and when adding new APIs we will
only make them available on the canonical object path.

For the files in gio/ (but not in gio/ sub-directories), only the *.[ch]
files were handled in commit 3bf4a720c3.
For the modified files in glib/tests/markups/, I've tested that
`make check` still succeeds.
After this commit,
$ git grep -in "GNU Library"
and
$ git grep -in "Library General"
return only results in COPYING files and in glib/libcharset/. The latter
was not updated because it's a copy.
$ git grep -in "version 2" | grep -iv "version 2\.1"
now doesn't return any LGPL license header.

If g_dbus_unwatch_name() is called from one thread at the same time as
the GDBusConnection is emitting ::disconnected in another thread, there
will be a race and the handler for ::disconnected may end up using
memory after it’s freed.
Fix this by serialising through the map_id_to_client, so that
on_connection_disconnected() atomically gets a strong reference to the
Client, or NULL.

Previously, this was done at the time of spawning the subprocess, which
meant the g_subprocess_launcher_*_environ() functions could not be used
to modify the parent process’ environment.
Change the code to copy the parent process’ environment when
