GCC 8 on F29 complains:
../tests/gio-test.c: In function ‘main’:
../tests/gio-test.c:375:7: warning: ‘id’ may be used uninitialized in this function [-Wmaybe-uninitialized]
g_free (id);
^~~~~~~~~~~
In the normal case, when run without arguments, 'id' will be assigned
exactly once, so all is fine. If run with argument '0', 'id' will never
be assigned, so the warning is legit; but in that case the test program
will never exit. If run with any argument greater than 1, 'id' will be
assigned more than once but only the last incarnation will be freed.
Tweak the scope of the variable to match its use, and arrange for it to
be freed when its watch is destroyed.
Closures use a 16-bit atomic reference count, which is really slow
on certain ARM64 CPUs such as the Cortex-A57 (glib#1316). This is
non-trivial to solve, since the public struct field cannot be enlarged
to 32-bit while preserving ABI, and 16-bit atomic operations would be new
(and rather niche) API.
Until this can be solved properly (hopefully in GLib 2.59.x), cut down
the number of signal emission cycles and bump up the timeout in the
Meson build system, so that builds won't time out. We can't just take
another zero off the number of signal emission cycles, as was done in the
original version of this patch in Debian, because if we do that it can
result in test failures when the main thread starves the other threads.
ARM64 CPUs are backwards-compatible with 32-bit ARM, and the same
slowdown can be seen when building and testing 32-bit code on these
CPUs, so check for both 32- and 64-bit ARM.

This reverts commits:
• 9ddcc79502
• ae02adc3c3
g_date_time_format() supports a few non-standard format placeholders:
• %:z
• %::z
• %:::z
These are all gnulib strtime() extensions, and hence are not recognised
by the compiler when the function is annotated with G_GNUC_STRFTIME.
However, this wasn’t noticed when we originally merged this change
because the errors were disabled in the tests which covered those
placeholders.
* Wait for adder threads before deallocating crawler_array and
context_array to avoid use after-free and data race.
* Handle spurious wakeups around g_cond_wait.
* Avoid starting recurser_idle without context.
Fixes issue #1530.
If we tell clang that we're passing the arguments on to a compatible
printf call, it can see that we're doing it right, and won't warn us
about -Wformat-nonliteral. This follows up from commit abac67c0.

This makes it easier to debug test failures, by ensuring that g_debug()
and g_test_message() are printed as TAP diagnostics.

As we recently established, G_G*_FORMAT macros are for glib
functions *only*. It's not guaranteed that they will work for
C runtime printf() or scanf() variants, and indeed - in this case
they do not (GCC thinks that MSVCRT sscanf() requires %I64 prefix
for 64-bit values; whether that is true or not is irrelevant at this
point - we need to make the werror go away).
LPARAM is LONG_PTR which is the same as INT_PTR on Windows.
WPARAM is UINT_PTR.
HWND is a pointer.
(%p prints pointers without 0x prefix, hence the extra 0x).
These keep on taking just longer than 30s on my local machine when run
in parallel with the rest of the tests (i.e. with `ninja test`). Testing
them individually, they do terminate correctly.

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.
This brings the autotools-generated tarball in line with the
ninja-generated one, with the exception of man pages and gtk-doc HTML
output.

It's been 4 years and 8 development cycles since we introduced
G_ADD_PRIVATE and offset-based private data access. It is now
time to finally deprecate the old mechanism.
Closes: #699
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.
This fixes:

The existing implementation was completely incorrect (despite the fix in
commit 566e64a66) — it always compared GVariants by pointer, rather than
by value.
Reimplement it to compare them by value where possible, depending on
their type. The core of this implementation is g_variant_compare(). See
the documentation and tests for further details of the new sort order.
This adds documentation and tests.

Getting the canonical filename is a relatively common
operation when dealing with symbolic links.
This commit exposes GLocalFile's implementation of a
filename canonicalizer function, with a few additions
to make it more useful for consumers of it.
Instead of always assuming g_get_current_dir(), the
exposed function allows passing it as an additional
parameter.
This will be used to fix the GTimeZone code to retrieve
the local timezone from a zoneinfo symlink.
(Tweaked by Philip Withnall <withnall@endlessm.com> to drop g_autofree
usage and add some additional tests.)

All those logging functions already add a newline to any message they
print, so there’s no need to add a trailing newline in the message
passed to them.

It seems that when GLib is compiled without CFLAGS=-g, gdb can’t work
out the size of __glib_assert_msg, so assumes it’s 4 bytes — even on
64-bit systems. This causes it to not read the most significant 4 bytes
of the assertion message pointer, and hence it can’t print the stored
assertion message. This causes assert-msg-test to fail.
The upstream gdb bug is
https://sourceware.org/bugzilla/show_bug.cgi?id=22501.
Work around that by referencing and dereferencing __glib_assert_msg so
that gdb treats it as a pointer of sizeof(char*) rather than of the size
it incorrectly calculated from the library’s symbol table (or through
some other mystical process).

It is outdated and no longer effectively used. It was originally in
place to prevent rebuilding generated files (from a tarball) if the
right build tools (awk, Perl, indent) were not available. However, we no
longer use indent, we have hard-required awk for a while, and the only
places the @REBUILD@ substitution was still used were for
glib-genmarshal, which has recently been rewritten in Python (so no
longer depends on whether Perl is available).
Drop the whole lot.
