g_utf8_make_valid was turned into a public API this cycle. However
now that it is public we should make the API more generic, allowing
the caller to specify the length. This is especially useful if
the function is called with a string that has \0 in the middle
or for chunks of a strings that are not nul terminated.
This is also consistent with most of the other utf8 utils.
Callers inside glib are updated to the new signature.

In my previous attempt to improve colored console output on Windows, we
called GetFileInformationByHandleEx() directly if we target Vista or
later, but the check macro for doing so via LoadLibrary() had a typo. Fix
this by correcting the check macro.

It has the same block size as SHA-512, so it just needs a new case in

As we currently cannot generate UUIDs with curly braces, or as URNs,
remove those from the possible valid UUIDs.
We do this separately to make it easier to re-add later, should we want
to enhance the coverage of our UUID functions.

Many UUID users will just need a random string, which can be generated
simply by calling the function g_uuid_string_random().

It’s hard to know whether trying to load a non-existent key file will
result in G_KEY_FILE_ERROR_NOT_FOUND or G_FILE_ERROR_NOENT; try to
improve the documentation to clarify that.

Clarify that g_key_file_get_integer() and g_key_file_get_integer_list()
both return G_KEY_FILE_ERROR_INVALID_VALUE if used to load a valid
integer which is out of range for a gint.
Don't refer to g_mkdtemp() when documenting g_mkdtemp_full() and
speaking about the function itself, and remove mention of flags in
aforementioned g_mkdtemp_full(), as it doesn't have such an argument
(but g_mkstemp_full() does).

It was suggested that the project files be moved here as we don't actually
need to go two directory layers from $(srcroot), and would help us to
standardize on things in the future across the board.
We kept seeing the glib testsuite hanging on our CI system in the
testcase for 642026. After some digging it turned out the jenkins slave
was misconfigured and its task limit was too low.
Add an assertion that the test thread has been created to more easily
spot this error condition as opposed to the test simply hanging.

... when tty terminal emulators (such as mintty) are used. This support
is however for Vista and later, so use of such terminals should have
support for ANSI color codes in their outputs, even on Windows 7/8/8.1/
https://bugzilla.gnome.org/show_bug.cgi?id=775468
Windows 10 begins to support color output on the console using ANSI
codes, but a few extra steps are required for this support, so we cannot
just use isatty() and expect colors to work in the outputs.
Instead, we use still use isatty() from the Windows CRT, and then enable
ENABLE_VIRTUAL_TERMINAL_PROCESSING if it returns true.
Also make the invalid parameter handler shared between gmessages.c and
gspawn-win32-helper.c, since it is basically intended to be a no-op stub.

Signed integer overflow is undefined behaviour, which the undefined
behaviour sanitizer detects.
Previously, if the compiler had implemented this in the obvious way
(overflowing signed multiplication wraps around mod 2**32), we would
have incorrectly classified addresses where one octet was, for example,
(2**32 + 42) as valid IP addresses, by treating that octet as though
it was 42.

glibc string.h declares memcpy() with attribute(nonnull(1,2)), causing
calls with NULL arguments to be treated as undefined behaviour.
This is consistent with ISO C99 and C11, which state that passing 0
to string functions as an array length does not remove the requirement
that the pointer to the array is a valid pointer.
gcc -fsanitize=undefined catches this while running OSTree's test suite.
Similarly, running the GLib test suite reports similar issues for
qsort(), memmove(), memcmp().

global variables in SystemTap are shared between all SystemTap scripts;

If we have an input parameter (or return value) we need to use (nullable).
However, if it is an (inout) or (out) parameter, (optional) is sufficient.
It looks like (nullable) could be used for everything according to the
Annotation documentation, but (optional) is more specific.
The GVariant documentation says you can assume that types of no more
than 32 bits may be assumed to be promoted to int by the usual
promotions. If we're going to document that, we should statically
assert that it's true, i.e. sizeof (int) >= sizeof (int32_t).
All reasonable modern platforms are either ILP32 (32-bit platforms),
LP64 (64-bit Linux, *BSD etc.), or LLP64 (64-bit Windows): there have
been ILP64 platforms in the past, but ILP64 has the compelling
disadvantage that {signed char, short, int} can't possibly provide
all of {int8_t, int16_t, int32_t} unless int is 32 bits long.

ISO C allows compilers to make enums smaller than int if their
enumerated values would all fit in the range of a smaller type.
In practice, I suspect that in relevant compilers, all enums whose
values fit in the range INT32_MIN to INT32_MAX (inclusive) are the same
size as int. ISO C allows compiler to break that assumption, but those
that do would break code that works fine in other compilers, making the
compiler look bad, for no significant benefit. I conjecture that such
compilers are not popular.
Let's statically assert that my assumption holds. If all goes well,
GLib will continue to compile on every relevant platform; if it
fails to compile on some platform as a result of this change, then
there are probably a lot of naive uses of enums that need auditing
for this assumption.

This code assumes that int is exactly 32 bits, and that pointers
are either 4 or 8 bits, on platforms with __ATOMIC_SEQ_CST.
In practice this is going to be true.
A previous attempt at this assertion placed the G_STATIC_ASSERT
at the top level in gatomic.h, but that broke anjuta, which
redefined __unused__ at the time. These assertions are about the
platform/compiler ABI, so it's sufficient to check them once,
while compiling GLib itself; accordingly, move them to the
implementation.

g_assert() gets completely compiled out if G_DISABLE_ASSERT is defined,
so applications should not depend on side effects of the expression in
an assertion.
Clarify that the arguments parameter can be zero if the function being
annotated just accepts a string format argument, and no varargs for it
(for example, if it takes a va_list of arguments instead).
Add some links to the GCC documentation for the `format` attribute.
This commit broke some tests, and I don't have the time
to fix up all the expected output, so I'll revert the changes
to the affected files for now.
This needs to be redone with the necessary test fixes.

According to https://msdn.microsoft.com/en-us/library/zs6wbdhx.aspx:
If stdout or stderr is not associated with an output stream (for
example, in a Windows application without a console window), the file
descriptor returned is -2. In previous versions, the file descriptor
returned was -1. This change allows applications to distinguish this
condition from an error.
Check if the stream exists and has an associated descriptor and return
G_LOG_WRITER_UNHANDLED if it's not the case.
