It causes the tests to fail, which suggests some latent FD handling bug
on macOS (but not other platforms).
Unfortunately I’m unable to debug that due to not having access to a
macOS machine, and it’s blocking CI for the rest of the project.
So disable it on macOS for now, until someone with access to a macOS
machine can take a look.

Return `G_VARIANT_PARSE_ERROR_RECURSION` from `g_variant_parse()` if a
typedecl is found within a text-form variant which would cause any part
of the variant to exceed the maximum allowed recursion/nesting depth.
This fixes an oversight when `G_VARIANT_MAX_RECURSION_DEPTH` was
implemented, which allowed typedecls to effectively multiply the size of
an array if `g_variant_parse()` was parsing a text-form variant without
a top-level concrete type specified.

At the moment, glib assumes that if /etc/localtime is a symlink,
that it's a symlink to zoneinfo file.
Toolbx containers add an extra layer of indirection though, making
it a symlink to a symlink to a zoneinfo file.
This commit deals with the problem, by performing additional checks
on /etc/localtime and ignoring it if those check fail, falling back
instead to reading /etc/timezone.
The previous text was technically correct, but not very clear what
happens with the ownership of the key/value if it was not returned.
Elaborate on the fact, that the key/value is never destroyed, even if
not requested by the user.
I intuitively expected the function to behave differently, that is, to
destroy the key/value if (and only if) it was not returned. That is,
when the function does not return a pointer, then it would destroy it.
That would seem more consistent to me, where ownership is either
transferred to the caller, or the resource destroyed during the steal.
On the other hand, the existing behaviors is:
- is consistent with g_hash_table_steal() and never destroys key/value.
- behaves the same, regardless whether the key/value was returned.
So the existing behavior may be better.
Just elaborate on that detail in the doc.
An application must keep track of the file descriptors that it
has. Closing an invalid, non-negative file descriptor is usually
a bug, because it indicates somebody messed up the tracking.
On a single threaded application it may be fine, but EBADF is always a bug
in a multi threaded application because another thread might race
reusing the bad file descriptor. With GDBus and other glib API, it is very
common that your application has multiple threads running and this is
in fact a bug.
The assertion failure does not necessarily indicate that the bug
is in the caller. It could have been another part of the application
that wrongly closed the file descriptor.
Otherwise the test will fail when run in a non-English locale.

* Add a test to check that smaller string than prefix/suffix are
handled in g_str_has_*() functions.
* Add a tests on macro prefixed function and ensure that function
itselves are tested as well.
Compilers can emit optimized code for str|strn|mem)cmp(str,"literal")
at compile-time. This commit use the preprocessor to introduce this
kind of optimization for the functions g_str_has_prefix() and
g_str_has_suffix().

There is no guarantee that the thread pool will reach its limit afaict,
it depends how the system schedule the various threads. This fixes

GBookmarkFile has everything for being introspectable, but it lacks a
GType, because it can't be copied. So provide a copy function that
deeply copies all the bookmark structures.
Add tests for this.
In some bookmarks that we load the modified value may be not set, while
this may lead to a load error, we still can dump such file and this
would fail as we try to get a string from an invalid time.
Avoid this, because it would also lead to not writing a valid count
value, given that we'd pass NULL to g_strconcat too early.
This is like our other suite of g_set_*() based APIs to simplify and
improve correctness of setters for fields, properties, and more.
This implementation specifically handles setting string values that may
point to an offset within the current string by copying before free.
strcmp() is used directly (as opposed to g_strcmp0() due to it being in
gtestutils.h as well as to increase the chance that the compiler will
hoist the implementation.
Fixes#2747
There is currently no `dllimport` attribute on any of our function,
which prevents MSVC to optimize function calls.
To fix that issue, we need to redeclare all our visibility macros for
each of our libraries, because when compiling e.g. GIO code, we need
dllimport in GLIB headers and dllexport in GIO headers. That means they
cannot use the same GLIB_AVAILABLE_* macro.
Since that's a lot of boilerplate to copy/paste after each version bump,
this MR generate all those macros using a python script.
Also simplify the meson side by using `gnu_symbol_visibility : 'hidden'`
keyword argument instead of passing the cflag manually.
This leaves only API index to add manually into glib-docs.xml when
bumping GLib version. That file cannot be generated because Meson does
not allow passing a buit file to gnome.gtkdoc()'s main_xml kwarg
unfortunately.
Not that we ever expect it to fail. This is basically just to silence a
compiler warning with `-Werror=unused-result`.

Otherwise, the build will fail when the toolchain is static-only, even
with -Ddefault_library=static. I talked to a Meson developer in their
IRC channel, who told me that the correct fix was to ensure that
shared_library is only used if default_library != static.
g_str_equal() is a nicer API than strcmp()==0, and less error prone.
However, forcing a function call prevents compiler from doing
optimizations. In the case it is not used as callback to GHashTable,
provide a macro that calls strcmp directly. This also has the side
effect that it forces arguments to be `const char *` instead of
`gconstpointer` in the case it is not used as callback, which adds type
safety.
