Add a pair of functions for returning strings that don't need to be
freed. This is a bit of a hack but it will turn the 99% case of using
these functions from:
gchar *tmp;
tmp = g_test_build_filename (...);
fd = open (tmp, ...);
g_free (tmp);
to:
fd = open (g_test_get_filename (...), ...);
which is a pretty substantial win.

g_test_trap_fork() doesn't work on Windows and is potentially flaky on
unix anyway given the fork-but-don't-exec. Replace it with
g_test_trap_subprocess(), which re-spawns the same program with
arguments telling it to run a specific (otherwise-ignored) test case.
Make the existing g_test_trap_fork() unit tests be unix-only (they
never passed on Windows anyway), and add a parallel set of
g_test_trap_subprocess() tests.
Also fix the logic of gtestutils's "-p" argument (which is used by the
subprocess tests); previously if you had tests "/foo/bar" and
"/foo/bar/baz", and ran the test program with "-p /foo/bar/baz", it
would run "/foo/bar" too. Fix that and add tests.

Lots of people have variously asked for APIs like
g_variant_new_string_printf() in order to avoid having to use
g_strdup_printf(), create a GVariant using g_variant_new_string(), then
free the temporary string.
Instead of supporting that, plus a million other potential cases,
introduce g_variant_new_take_string() as a compromise.
It's not possible to write:
v = g_variant_new_take_string (g_strdup_printf (....));
to get the desired result and avoid the extra copies. In addition, it
works with many other functions.

There are two benefits to this:
1) We can centralize any operating system specific knowledge of
close-vs-EINTR handling. For example, while on Linux we should never
retry, if someone cared enough later about HP-UX, they could come by
and change this one spot.
2) For places that do care about the return value and want to provide
the caller with a GError, this function makes it convenient to do so.
Note that gspawn.c had an incorrect EINTR loop-retry around close().

Adding file descriptors to a GSource provides similar functionality to
the old g_source_add_poll() API with two main differences.
First: the list of handles is managed internally and therefore users are
prevented from randomly modifying the ->events field. This prepares us
for an epoll future where changing the event mask is a syscall.
Second: keeping the list internally allows us to check the ->revents for
events for ourselves, allowing the source to skip implementing
check/prepare. This also prepares us for the future by allowing an
implementation that doesn't need to iterate over all of the sources
every time.

When running a test program (ie, if g_test_init() has been called),
don't pop up a dialog box when a fatal error occurs. Just print the
message to stderr and exit.

We need to have some more discussion on this topic.
This reverts commits 86329ba44fc7662c0bad37955f0ec980a24be495 and

For some time now people have been asking for a way to check for type
compatibility between GVariant instances and format strings. There are
several APIs inside of GLib itself that would benefit from this.
This patch introduces a way to do that.
Add a variant of g_markup_collect_attributes() which will
ignore unknown attributes (such as those from different XML
namespaces) when parsing markup, rather than returning
G_MARKUP_ERROR_UNKNOWN_ATTRIBUTE as g_markup_collect_attributes()
does.

Many (if not "almost all") programs that spawn other programs via
g_spawn_sync() or the like simply want to check whether or not the
child exited successfully, but doing so requires use of
platform-specific functionality and there's actually a fair amount of
boilerplate involved.
This new API will help drain a *lot* of mostly duplicated code in
GNOME, from gnome-session to gdm. And we can see that some bits even
inside GLib were doing it wrong; for example checking the exit status
on Unix, but ignoring it on Windows.

The docs for GString should really mention GByteArray, and what makes
it different. Drop the comparison to Java which is dated and actually
inaccurate (because StringBuffer operates on Unicode).
While we're here, add g_string_free_to_bytes(), which further
complements the spread of GBytes-based API. For example, one can
create a buffer using GString, then send it off via
g_output_stream_write_bytes().

They make a full (deep) copy of a list.
In contrast with g_[s]list_copy(), these functions take a function as a argument
to make a copy of each list element, in addition to copying the list container itself.
The functions g_[s]list_copy() were reimplemented to just call the new functions
with NULL as the function argument, which will behave like current implementation.

There are cases when it should be possible to define at compile time
what range of functions and types should be used, in order to get,
or restrict, the compiler warnings for deprecated or newly added
types or functions.
For instance, if GLib introduces a deprecation warning on a type in
version 2.32, application code can decide to specify the minimum and
maximum boundary of the used API to be 2.30; when compiling against
a new version of GLib, this would produce the following results:
- all deprecations introduced prior to 2.32 would emit compiler
warnings when used by the application code;
- all deprecations introduced in 2.32 would not emit compiler
warnings when used by the application code;
- all new symbols introduced in 2.32 would emit a compiler warning.
Using this scheme it should be possible to have fairly complex
situations, like the following one:
assuming that an application is compiled with:
GLIB_VERSION_MIN_REQUIRED = GLIB_VERSION_2_30
GLIB_VERSION_MAX_ALLOWED = GLIB_VERSION_2_32
and a GLib header containing:
void function_A (void) GLIB_DEPRECATED_IN_2_26;
void function_B (void) GLIB_DEPRECATED_IN_2_28;
void function_C (void) GLIB_DEPRECATED_IN_2_30;
void function_D (void) GLIB_AVAILABLE_IN_2_32;
void function_E (void) GLIB_AVAILABLE_IN_2_34;
any application code using the above functions will get the following
compiler warnings:
function_A: deprecated symbol warning
function_B: deprecated symbol warning
function_C: no warning
function_D: no warning
function_E: undefined symbol warning
This means that it should be possible to gradually port code towards
non-deprecated API gradually, on a per-release basis.

Add new macros to disable -Wdeprecated-declarations around a piece of
code, using the C99 (and GNU89) _Pragma() operator. Replace the
existing use of #pragma for this in gio, and suppress the warnings in
gvaluearray.c as well.

Like GPtrArray has a "free function" that can be used to free memory
associated to each pointer in the array, GArray would benefit from
having a "clear function" that can be used to clear the content of
each element of the array when it's removed, or when the entire array
is freed.

Raised by Matthias in bgo#665685 but which I didn't spot until after pushing
commit 3ac7c35656649b1d1fcf2ccaa670b854809d4cd8.
Renames G_UNICHAR_MAX_DECOMPOSITION_LEN to G_UNICHAR_MAX_DECOMPOSITION_LENGTH
and fixes a few documentation issues.
See: bgo#665685
* Represents an immutable reference counted block of memory.
* This is basically the internal glib GBuffer structure exposed,
renamed, and with some additional capabilities.
* The GBytes name comes from python3's immutable 'bytes' type
* GBytes can be safely used as keys in hash tables, and have
functions for doing so: g_bytes_hash, g_bytes_equal
* GByteArray is a mutable form of GBytes, and vice versa. There
are functions for converting from one to the other efficiently:
g_bytes_unref_to_array() and g_byte_array_free_to_bytes()
* Adds g_byte_array_new_take() to support above functions

We clean up the detection of if we should do 'real' atomic operations or
mutex-emulated ones with the introduction of a new (public) macro:
G_ATOMIC_LOCK_FREE. If defined, our atomic operations are guaranteed to
be done in hardware.
We need to use __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 to determine if our
compiler supports GCC-style atomic operations from the gatomic.h header
because we might be building a program against GLib using a different
set of compiler options (or a different compiler) than was used to build
GLib itself.
Unfortunately, this macro is not available on clang, so it has currently
regressed to using the mutex emulation. A bug about that has been
opened here:
