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.
Make it a bit more obvious when the DTLS methods aren’t implemented by a
particular TLS backend; return an invalid type rather than crashing.

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
GSubprocess which is already known to be dead).
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.
Thanks to Will Thompson for some very useful unit tests which reproduce
this (which will be pushed in the following commit).

Some of the dependencies' build systems for Visual Studio do not provide a
pkg-config file upon build, so we use find_library() for them when the
corresponding pkg-config files are not found during Visual Studio builds,
so that one will not need to make up pkg-config files for them, which
could be error-prone. These .lib names match the names that are built
with the officially supported build system that is used by their
respective Visual Studio support.
For ZLib, this will make gio-2.0.pc reflect on the zlib .lib based on
what is found, or whether we use the fallback/bundled ZLib, when we
don't have a pkg-config file for ZLib on MSVC. We still need to depend
on Meson to be updated to put the correct link argument for linking ZLib
in the pkg-config case.

Mention that it really is a good idea to save errno before doing
literally anything else after calling a function which could set it.
Signed-off-by: Philip Withnall <withnall@endlessm.com>
https://bugzilla.gnome.org/show_bug.cgi?id=785577
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.

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.

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
https://bugzilla.gnome.org/show_bug.cgi?id=784133
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).

add a check in GIO to use different error numbers on these systems.

Otherwise, we might end up returning TRUE from

(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
