If a given fd is being polled by multiple sources, we used to pass it
multiple times to g_poll(), which is technically illegal (and not
supported by the select()-based fallback implementation of poll() in
gpoll.c), and also made it more likely that we'd exceed the maximum
number of pollfds.
Fix it to merge together "duplicate" GPollFDs. The easiest way to do
this involves re-sorting context->poll_records into fd order rather
than priority order. This means we now have to walk the entire pollrec
list for every g_main_context_query() and g_main_context_poll(),
rather than only walking the list up to the current max_priority.
However, this will only have a noticeable effect if you have tons of
GPollFDs, and we're already too slow in that case anyway because of
other O(n) operations that happen too often. So this shouldn't change
much (and the new poll API will eventually let us be cleverer).
Remove some win32-specific code which did the same thing (but was
O(n^2)).

We called getopt() to try to find out of the platform on which we are
running defaults to strict POSIX-style argument handling (ie: flags
following the first filename are considered as further filenames rather
than flags).
This is the default case on BSDs, for example. It is also the case on
GNU systems with the POSIXLY_CORRECT environment variable set.
Unfortunately many of our tools rely on being able to accept commandline
arguments in the non-strict ordering and the code for making these calls
is spread widely (for example in Makefile fragments invoking some of our
build tools).
For this reason we need to revert the getopt() check and only enable
strict POSIX mode in the case that the application explicitly opts into
it using the _set_strict_posix() API.
This also fixs a failure to build on Windows due to missing getopt().

Add a "posixly correct" mode to GOption to stop parsing arguments as
soon as the first non-option argument is encountered.
We determine the default value on the basis of duplicating the behaviour
of the system getopt() implementation (which we directly check the
behaviour of at runtime). On GNU systems this allows the user to modify
our behaviour using POSIXLY_CORRECT.
The user can change the value by g_option_context_set_strict_posix(),
which might be useful for some usecases of GOptionContext (as mentioned
in the doc string of this new function).

Document that one must not use the "by id" source APIs with non-existent
IDs. The real justification behind this restriction is that the reuse
of source ids makes it unsafe to call these functions unless you're
absolutely sure that the source exists and it belongs to you. If you
call one of these functions on a source that may already have been
removed then you run the risk of finding someone else's source (with
your reused id).
This also bails us out of a slightly tricky situation with respect to
the threadsafety of g_main_context_find_source_by_id(). The fact that
this function doesn't return a reference implies that its return value
cannot be safely accessed unless we already know for sure that a
reference is being held elsewhere (by example, by the main context
itself if we know that the source has not been removed). The function
itself, however, performs an access to the value, which could result in
a crash.
If we mandate that it is only valid to call this function on
known-to-exist source IDs then we dodge this problem.

This confused me for a while, because it isn't the same as D-Bus.
Like GVariant, the D-Bus serialization needs an out-of-band
endianness and type indicator, but unlike GVariant, serialized
D-Bus objects encapsulate their own length (often by starting with
a byte-count). This does come at some redundancy cost, so I can see
why the more efficient GVariant format does this the way it does;
but it's a difference between D-Bus and GVariant that seems worth
calling out.
It's also relevant for the designers of file or message-framing
formats: with D-Bus serialization it would be feasible to say "the file
starts with a little-endian D-Bus variant, followed by...",
but in GVariant you wouldn't be able to deserialize the variant
unless you either assume that it extends to end-of-file, or have
an explicit length.

Practically no caller of these functions require atomic behaviour,
but the atomics are much slower than normal operations, which makes
it desirable to get rid of them. We have not done this before because
that would be a break of the ABI.
However, I recently looked into this and it seems that even if the
atomics *are* used for g_clear_* it is not ever safe to use this. The
atomics protects two threads that are racing to free a global/shared
object from freeing the object twice. However, any *user* of the global
object have no protection from the object being freed while in use,
because there is no paired operation the reads and refs the object
as an atomic unit (nor can such an operation be implemented using
purely atomic ops).
So, since nothing could safely have used the atomic aspects of these
functions I consider it acceptable to just remove it.

Detect the following two errors:
- attempting to unlock a mutex that is not locked
- attempting to clear a mutex that was not initialised or was

Both of these are fatal errors. We avoid using g_error() here because

If we have futex(2) then we can implement GMutex natively and gain a
substantial performance increase (vs. using pthreads).
This also avoids the need to allocate an extra structure in memory when
using GMutex or GCond: we can use the structure directly.
The main reason for the increase in performance is that our
implementation can be made more simple: we don't need to support the
array of options on pthread_mutex_t (which includes the possibility, for
example, of being recursive).
The result is a ~30% improvement in uncontended cases and a much larger
increase (3 to 4 times) in contended cases for a simple testcase.

When GLib had been told to expect message X, but then actually saw
message Y, it would log the "did not see expected message" error with
message Y's log level and domain, which makes no sense. Change it to

Also, include the expected domain in the error message, so that if
that's the reason why the expectation didn't match, you can tell that

Move width table generation into the gen-unicode-tables.pl script. This makes
updating the tables automatic without the previously required manual editing
required to insert the tables in the right place of the source code.
memcmp() is declared by glibc as follows:
/* Compare N bytes of S1 and S2. */
extern int memcmp (const void *__s1, const void *__s2, size_t __n)
__THROW __attribute_pure__ __nonnull ((1, 2));
despite the fact that it is valid to call it with a null pointer if the
size is zero.
gcc 4.9.0 contains a new optimisation that sees that we pass a pointer
to this function and concludes that it certainly must not be null,
removing a later check and thereby causing a crash.
We protect the invocation of memcmp() with a condition to prevent gcc
from making this false assumption (arguably under wrong advice from
glibc).
The code in g_wakeup_signal() is currently correct: it writes a 64-bit
counter increment value if the FD is an eventfd, and writes an arbitrary

However, the reasoning behind these buffer sizes is not clear, and the
mismatch between the allocated buffer size and the length passed to
write() in the pipe case could be mistaken for a bug.

Fortunately, both of these platforms seem to share

g_cond_wait_until() without races.
With this patch, we now require that one of pthread_condattr_setclock()
or pthread_cond_timedwait_relative_np() exists. A quick look around
suggests that this is true for all platforms that we care about.

https://bugzilla.gnome.org/show_bug.cgi?id=721947
Add g_option_context_parse_strv() that obeys the normal memory conventions for
dealing with a strv instead of assuming that we're dealing with the 'argv'
parameter to main().
This will help for using GOptionContext with GApplication.

The names of the month (and abbreviations) are specific to the Windows
system locale, so we need to use SetThreadLocale() to set the locale of
the running program to en-US so that it will parse "March" and "Sept" etc.
correctly.

Windows will not allow one to write to a temp file opened by g_mkstemp()
by opening another fd associated with it before one closes the fd that
is returned by g_mkstemp(), which will cause the test_save test to fail.
Fix this by using a variable to store the fd from g_mkstemp() and checking
it, and call close() on that variable before attempting to call
g_key_file_save_to_file() on the temp file as that will attempt to open
another fd (which would not work) associated with that temp file.

Fix some races introduced in be2c7b83c4
while keeping the property that multiple handlers for the same unix
signal all get dispatched.
Also fix the behaviour of the source checking for pending signals when
it's created. No matter what we do here (clear the pending flag or not)
there is something that can go wrong.
If we clear the flag, we may prevent other sources from being
dispatched. If we don't clear it, we may end up dispatching the same
source twice (if we manage to dispatch it from its own thread before the
GLib worker has a chance to run).
Instead, run the full dispatch procedure when a new source is added. It
actually doesn't matter what thread this runs in since the lock is held.

The existing tests were accidentally using the same test data
twice. Fix that, and add another set of tests that exercise
the filename collation special cases.
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.
This was a feature intended from the very beginning that somehow never
got written. It's a way to replace these sort of error messages out of
the GVariant parser:
1-2,10-15:unable to find a common type
with something in the style of the Vala compiler:
unable to find a common type:
[1, 2, 3, 'str']

Most GErrors, such as GSomethingError, have a function to get
their quark that looks like g_something_error_quark(),
so bindings (such as gtkmm) would expect GVariantParseError
to have g_variant_parse_error_quark(). Instead this had
g_variant_parser_get_error_quark().
This deprecates the old function and adds the correct one,
making life easier for gtkmm (and maybe others).

Change g_test_run() to return 1 on failure (rather than the number of
failed tests), and 77 if all tests are skipped (since automake and
some other test harnesses recognize that status code).
Previously g_test_run() returned the number of failed tests, but this
behavior was not documented, and at any rate, prior to 2.39,
g_test_run() would normally not return at all if an error occurred.

Allow g_test_trap_subprocess() to be used in a simple cases by
rerunning the same test case itself. This is accomplished by
passing %NULL as the test case name.

Since we are already building a deprecated function for compatibility
reasons, we don't really need to see a warning when it uses another
deprecated GLib function.
Commit e53caad4 makes _g_log_abort() noreturn by calling abort()
unconditionally.
However, it is useful to be able to skip some log_abort() with a
debugger, to reach a point of interest. Revert back to previous
behaviour. Make g_assert_warning() noreturn by calling abort().

When calculating the array sizes in get_contents_stdio(), there is a
possibility of overflow for very large files. Rearrange the overflow
checks to avoid this.
The code already handled some possibilities of files being too large, so
no new GError has been added to handle this; the existing
G_FILE_ERROR_FAILED is re-used.

This probably won’t crash, as it can only happen if (size == 0), but
add a check to be safe, and to shut up the static analyser.
This case can be reached with the following call:
gvs_read_unaligned_le(NULL, 0)
which can be called from:
gvs_tuple_get_child(value, index_)
with (value.data == NULL) and (value.size == 0).

Don't attempt to insert environmental variables in the hash table during
the test listenv that is an empty string, as GetEnvironmentStringsW() also
returns special enviroment variables which have empty strings as their
variable names, at least on Windows 7 and 8.

Make some of the conversion functions a bit more friendly to allocation
failure.
Even though the glib policy is to abort() on allocation failure by
default, it can be quite helpful to return an allocation error for
functions already providing a GError.
I needed a safer g_utf16_to_utf8() to solve crash on big clipboard
operations with win32, related to rhbz#1017250 (and coming gdk handling
bug).

g_test_init() was calling _g_messages_set_exit_on_fatal() from
subprocesses, to make fatal log messages call _exit() rather than
abort(), but the function name is sort of confusing, and we don't
really need it anyway, since g_log() can just call g_test_subprocess()
instead and decide for itself.
Likewise, update g_assertion_message() to do the check itself, rather
than calling into gmessages to do it, and fix
g_assertion_message_expr() to also check whether it should exit or
abort. (Previously it always called abort(), although this didn't
actually matter since that was dead code until
test_nonfatal_assertions was added.)
https://bugzilla.gnome.org/show_bug.cgi?id=711800
g_test_set_nonfatal_assertions() was a no-op, because
g_assertion_message() wasn't actually checking the
test_nonfatal_assertions flag. Fix that and add a test.
Also, g_test_set_nonfatal_assertions() has to set test_mode_fatal to
FALSE as well, or else a failed assertion will cause the test program
to abort at the end of the failed test.
Also, belatedly add this and the new g_assert_* methods to the docs.

g_array_remove_range and g_byte_array_remove_range return
a pointer to the array, g_ptr_array_remove_range returns
void. Since it is pretty harmless, make it return the array
too.

Declare that the previously-unused "..." argument to g_test_init() is
actually a NULL-terminated list of strings indicating testing options,
and add an option "no_g_set_prgname", which keeps g_test_init() from
calling g_set_prgname(). Then we can port glib/tests/option-argv0 to
use gtester, by passing that option.

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.

Assume unix platforms support the original POSIX.1 standard.
Specifically, assume that if G_OS_UNIX, then we have chown(),
getcwd(), getgrgid(), getpwuid(), link(), <grp.h>, <pwd.h>,
<sys/types.h>, <sys/uio.h>, <sys/wait.h>, and <unistd.h>.
Additionally, since all versions of Windows that we care about also
have <sys/types.h>, we can remove HAVE_SYS_TYPES_H checks everywhere.
Also remove one include of <sys/times.h>, and the corresponding
configure check, since the include is not currently needed (and may
always have just been a typo for <sys/time.h>).
https://bugzilla.gnome.org/show_bug.cgi?id=710519
Assume all supported platforms implement C90, and therefore they
(correctly) implement atexit(), memmove(), setlocale(), strerror(),
and vprintf(), and have <float.h> and <limits.h>.
(Also remove the configure check testing that "do ... while (0)" works
correctly; the non-do/while-based version of G_STMT_START and
G_STMT_END was removed years ago, but the check remained. Also, remove
some checks that configure.ac claimed were needed for libcharset, but
aren't actually used.)
Note that removing the g_memmove() function is not an ABI break even
on systems where g_memmove() was previously not a macro, because it
was never marked GLIB_AVAILABLE_IN_ALL or listed in glib.symbols, so
it would have been glib-internal since 2004.

Remove workarounds for NeXTStep (last released in 1995), SunOS (1994),

4.x (1999), and AIX 4.x (1999).
HP-UX 11 implements dlopen(), so dropping support for earlier versions
also lets us remove the HP-UX-specific gmodule-dld.

Since the initial addition of BeOS support in 1999, there has only
been one update to it (in 2005, and it wasn't even very big). GLib is
known to not currently build on Haiku (or presumably actual BeOS)
without additional patching, and the fact that there isn't a single
G_OS_BEOS check in gio/ is suspicious.
Additionally, other than the GModule implementation, all of the
existing G_OS_BEOS checks are either (a) "G_OS_UNIX || G_OS_BEOS", or
(b) random minor POSIXy tweaks (include this header file rather than
that one, etc), suggesting that if we were going to support Haiku, it
would probably be simpler to treat it as a special kind of G_OS_UNIX
(as we do with Mac OS X) rather than as its own completely different
thing.
So, kill G_OS_BEOS.

Skip the tests on inf/nan strings for the gvariant and strfuncs tests, and
skip the hex strings for the strtod tests in strfuncs as they are C99
features that are not yet supported by Visual C++ (even 2013). Use a
definition for NAN and INFINITY (that is also used in PyGObject) as
atof("NaN") and atof("Infinity") simply returns 0.0 (which is not a NAN)
in Visual C++ to fix the tests running there.
Also adapt to the format of g_ascii_formatd() when dealing with 1e99.

Use a Windows-style .bat script for the test_spawn_script() test, at least
when the code is built with Visual C++ (due to differences in how scripts
are written for shells and Windows cmd.exe), and account for Windows-style
line endings for that test too.
Let the MinGW builds (which are normally done in an MSYS BASH-style shell) continue to use the
*NIX-style script for that test.

Remove the parts about storing up the fd's in a data structure, but call
close() on the fd's. However, retain the _get_osfhandle() check on the
fd's when we iterate through the fd's as on fd values in the iteration may
well be invalid fd's. As a result, the invalid parameter handler is still
needed for newer Microsoft CRTs (8.0/2005+) for _get_osfhandle() to
make sure that the program does not abort when we check the validity of
fd's to be closed in the loop[1].

...Under various compilers when !G_DISABLE_CHECKS. Previously, the
messages that are logged differ depending whether GLib was built with GCC
or not. To simplify test cases, make all builds use a single output format
for g_return_if_fail(), g_return_val_if_fail(), g_return_if_reached(), and
g_return_val_if_reached(), by using the GCC-style format and replaceing
__PRETTY_FUNCTION__ with G_STRFUNC, so that it will work across various
compilers.
