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.)

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It is outdated and no longer effectively used.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).

Commit 31fde56 changed the way the private data is laid out in memory by
putting it *before* the instance data to keep the offsets fixed
regardless of the number of many subclasses.
This means that the invariant testgobject was verifying is no longer

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.

The Meson build has fallen a bit behind the Autotools one, when it comes
to the internally built tools like glib-mkenums and glib-genmarshals.
We don't need to generate gmarshal.strings any more, and since the
glib-genmarshal tool is now written in Python it can also be used when
cross-compiling, and without indirection, just like we use glib-mkenums.
We can also coalesce various rules into a simple array iteration, with
minimal changes to glib-mkenums, thus making the build a bit more
resilient and without unnecessary duplication.
gen-casefold-txt.pl and gen-casemap-txt.pl are licensed under GPLv2+, so
they are not touched by this commit.

We don't need to run binaries we just built in order to successfully
build GLib and friends any more.
Since commit b74e2a7, we don't need to run glib-genmarshal when building
GIO; since commit f9eb9eed, all our tests (including the ones that do
need to run binaries we just built) are only built when running "make
check", instead of unconditionally at every build.
This means that we don't need to check for existing, native binaries
when cross-compiling, and fail the configuration step if they are not
found — which also means that you don't need to natively build GLib for
your toolchain, in order to cross-compile GLib.
We can also use the cross-compilation conditional, and skip those tests
that require a binary we just built in order to build.

It turns out that due to a recent gdm change, the inherited
signal mask has SIGUSR1 blocked - which is bad news for
tests using SIGUSR1. Fix the test by explicitly checking the
signal mask before using SIGUSR1.
The mapping-test is failing under gnome-continuous. I suspect this
is simply due to running many tests in parallel, and mapping-test
being racy. Replace the blind sleep by signals, to avoid the
races.
g_time_val_from_iso8601 was attempting to parse strings
having only a date, but failed to actually set the timeval
despite returning TRUE. Since the docs state that the function
only parses strings containing a date and a time, just return
FALSE in this case.
Also remove an incomplete testcase for this behaviour that was
just checking the boolean return value, but not timeval.
In Windows development environments that have it, <unistd.h> is mostly
just a wrapper around several other native headers (in particular,
<io.h>, which contains read(), close(), etc, and <process.h>, which
contains getpid()). But given that some Windows dev environments don't
have <unistd.h>, everything that uses those functions on Windows
already needed to include the correct Windows header as well, and so
there is never any point to including <unistd.h> on Windows.
Also, remove some <unistd.h> includes (and a few others) that were
unnecessary even on unix.

Recent changes to the properties testcase made invalid use of the GArray
free function. This free function takes a pointer to the item to be
freed, not the item itself. Since that item was a pointer to a GObject,
g_object_unref() was getting a GObject**, rather than a GObject*.
The use of GArray in this testcase is pretty questionable in the first
place, so just use C arrays instead.
This commit adds a test to ensure that during a signal emission, if
a signal handler gets disconnected, it won't be run, even if it would
have run before the disconnection.
Perform a substantial cleanup of the build system with respect to
building and installing testcases.
First, Makefile.decl has been renamed glib.mk and substantially
expanded. We intend to add more stuff here in the future, like canned
rules for mkenums, marshallers, resources, etc.
By default, tests are no longer compiled as part of 'make'. They will
be built when 'make check' is run. The old behaviour can be obtained
with --enable-always-build-tests.
--disable-modular-tests is gone (because tests are no longer built by
default). There is no longer any way to cause 'make check' to be a
no-op, but that's not very useful anyway.
A new glibtests.m4 file is introduced. Along with glib.mk, this
provides for consistent handling of --enable-installed-tests and
--enable-always-build-tests (mentioned above).
Port our various test-installing Makefiles to the new framework.
This patch substantially improves the situation in the toplevel tests/
directory. Things are now somewhat under control there. There were
some tests being built that weren't even being run and we run those now.
The long-running GObject performance tests in this directory have been
removed from 'make check' because they take too long.
As an experiment, 'make check' now runs the testcases on win32 builds,
by default. We can't run them under gtester (since it uses a pipe to
communicate with the subprocess) so just toss them in TESTS. Most of
them are passing on win32.
Things are not quite done here, but this patch is already a substantial
improvement. More to come.
After this patch, there is but one remaining use of g_thread_init(),
which is in tests/slice-threadinit.c, a testcase dedicated to testing
the functionality of gslice across a g_thread_init() boundary.
This testcase is pretty meaningless these days... probably we should
delete it.
This should be the last users that need to be ported.
For some of the oldschool non-gtester-ified tests, we call g_test_init()
from main() because it is necessary in order to use
g_test_build_filename().
testgobject.c and timeloop-closure.c are the only two tests in the
toplevel tests/ directory that depend on gobject, so move them to
tests/gobject/ along with the other gobject tests.
Both of these were in noinst_PROGRAMS and not TESTS, so keep them that
way when we move them.
Back in the far-off twentieth century, it was normal on unix
workstations for U+0060 GRAVE ACCENT to be drawn as "‛" and for U+0027
APOSTROPHE to be drawn as "’". This led to the convention of using
them as poor-man's ‛smart quotes’ in ASCII-only text.
However, "'" is now universally drawn as a vertical line, and "`" at a
45-degree angle, making them an `odd couple' when used together.
Unfortunately, there are lots of very old strings in glib, and also
lots of new strings in which people have kept up the old tradition,
perhaps entirely unaware that it used to not look stupid.
Fix this by just using 'dumb quotes' everywhere.

By having gdb execute "set print elements 0" before printing the assert

unlimited.
