Certain compilers warn about unused functions if they are declared in
the header but are not inline. We require `static inline` support from
all compilers now.
Typically, this code will not be used, as the compilers we care about
implement vararg macro support; but this code path can still be hit on
some compilers (probably; unverified).

It can only fail if there’s been a leak or programmer error, so this is

Do the same for g_rw_lock_writer_lock().
It should be safe to use g_critical() for reporting the problems, since
GRWLock is not used in gmessages.c, and printing a critical seems better

This commit adds new W32-only functions to gstdio.c,
and a new header file, gstdioprivate.h.
These functions are:
g_win32_stat_utf8()
g_win32_lstat_utf8()
g_win32_fstat()
and they fill a private structure, GWin32PrivateStat,
which has all the fields that normal stat has, as well as some
extras.
These functions are then used throughout glib and gio to get better
data about the system. Specifically:
* Full, 64-bit size, guaranteed (g_stat() is forced to use 32-bit st_size)
* Full, 64-bit file identifier (st_ino is 0 when normal stat() is used, and still is)
* W32 File attributes (which stat() doesn't report); in particular, this allows
symlinks to be correctly identified
* Full, 64-bit time, guaranteed (g_stat() uses 32-bit st_*time on 32-bit Windows)
* Allocated file size (as a W32 replacement for the missing st_blocks)
st_mode remains unchanged (thus, no S_ISLNK), so when these are given back to
glib users (via g_stat(), for example, which is now implemented by calling g_win32_stat_utf8),
this field does not contain anything unexpected.
g_lstat() now calls g_win32_lstat_utf8(), which works on symlinks the way it's supposed to.
Also adds the g_win32_readlink_utf8() function, which behaves like readlink()
(including its inability to return 0-terminated strings and inability to say how large
the output buffer should be; these limitations are purely for compatibility with
existing glib code).
Thus, symlink support should now be much better, although far from being complete.
A new W32-only test in gio/tests/file.c highlights the following features:
* allocated size
* 64-bit time
* unique file IDs

The warnings issued when dealing with waitpid() raising ECHILD are
somewhat misleading: there are lots of reasons why waitpid() might
fail in this way, and we can't tell which one has happened.
In particular, passing a non-child or a non-pid, waiting for the same
pid elsewhere, or creating a duplicate watch for the same pid would
all fail in the same way.

As per further discussion on bug #781598, we can’t do this in GLib,

of GLib *must* do a header check (for example, using AC_CHECK_HEADERS)
and #include fcntl.h themselves.
It's ugly:
- The core method, g_iconv(), can't be annotated with good semantics.
- The error value of g_iconv_open() is not representable in today's

create or destroy a GData list, but they might still have an API

In fact, none of the functions dealing with GData** or a dataset
location pointer are likely to get sensible bindings anyway;
the annotations added are mostly to avoid memory unsafety
and leaks.

The HAVE_GOOD_PRINTF config variable determines whether we are able to
use the CRT-supplied *printf() functions directly, by determining whether
the CRT-supplied vsnprintf() and snprintf() functions support C99 well
enough.
This means, we need to build the gnulib subdir as a static lib in GLib, and use
the gnulib *printf() functions when:
-We are on Windows
-The CRT's vsnprintf() and snprintf() is not sufficiently C99-compliant.
This will fix the problem when the *printf() functions cause a CRT
abort() call on pre-2015 Visual Studio builds at least, and ensures that
the Visual Studio 2015+ builds will pass the printf tests in GLib, since
the *printf() in Visual Studio 2015/2017's CRT does not support the %n
format specifier, nor the positional parameters (which requires
different _*printf_p*() functions), as indicated by

Mention that it really is a good idea to save errno before doing

https://bugzilla.gnome.org/show_bug.cgi?id=785577
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.

WaitForMultipleObjectsEx() returns the index of the *first* handle that triggered the wakeup, and promises that all handles with lower index are still inactive. Therefore, don't check them, only check the handles with higher index. This removes the need of rearranging the handles (and, now, handle_to_fd) array, it's enough to take a pointer to the next item and use it as a new, shorter array.
https://bugzilla.gnome.org/show_bug.cgi?id=785468
Put all ptrs for GPollFDs that contribute handles into an array, the layout of which mirrors the handles array. This way finding GPollFD for a handle is a simple matter of knowing this handle's index in the handles array (which is something we always know). Removes the need to loop through all fds looking for the right one. And, with the message FD also passed along, it's now completely unnecessary to even pass fds to poll_rest() at all.
https://bugzilla.gnome.org/show_bug.cgi?id=785468
Instead of just indicating that messages should be polled for, save the pointer to GPollFD that contains G_WIN32_MSG_HANDLE, and pass it along. This way it won't be necessary to loop through all fds later on, searching for G_WIN32_MSG_HANDLE.
https://bugzilla.gnome.org/show_bug.cgi?id=785468
WaitForSingleObjectEx() is supposed to be a more efficient sleep method.
It waits on the handle of the current process. That handle will be signaled once the process terminates, and since we're *inside* the process, it'll never happen (and if it does, we won't care anymore).
The use of an alertable wait ensures that we wake up when a completion routine wants to run.

The original ready < nhandles - 1 can be re-written as ready + 1 < nhandles

WAIT_OBJECT_0 was not subtracted from ready in the if statement.

This reverts commit fd329f4853.
The commit changed the Introspection ABI, and it requires a change in
any application using an introspection-based language binding.
This is a stub-only library that can be used while building against
MSVC and contains no i18n machinery at all.
The dependencies added indirectly use the libintl.h header, and when
built as a subproject, the header won't be in a path known the
pre-processor.
Don't use it project-wide for building everything. Otherwise
symbols for shared modules won't be exposed, e.g. in the
resourceplugin used by the gio resource unit test.
Disable gio tests on Windows, fix .gitignore to not ignore
config.h.meson, and add more things to it.
Rename the library file naming and versioning to match what Autotools
outputs, e.g., libglib-2.0.so.0.5000.2 on Linux, libglib-2.0-0.dll and
glib-2.0-0.dll on Windows with MSVC.
Several more tiny fixes, more executables built and installed, install
pkg-config and m4 files, fix building of gobject tests.
Changes to gdbus-codegen to support out-of-tree builds without
environment variables set (which you can't in Meson). We now add the
build directory to the Python module search path.
Non-representable characters during UTF16->locale conversion
will cause gcov code to return an error, for which it will try
to use gettext, so that the error message is localized.
If such call is made while gettext is being initialized
(there's a g_once_init_enter up the stack), the thread will hang forever.
To solve this, use W32 API to do the UTF16->locale conversion
and don't use gettext when it returns an error.
Also optimize g_win32_locale_filename_from_utf8() a bit,
as we need more UTF16 and less UTF8 now.

The tool that extracts the translatable strings to .po files does not
cope with the G_GUINTX_FORMAT macros, so we preformat the numbers to
strings and use the strings in the translatable error messages.
Very often when we want to convert a string to number, we assume that
the string contains only a number. We have g_ascii_strto* family of
functions to do the conversion but they are awkward to use - one has
to check if errno is zero, end_ptr is not NULL and *end_ptr points to
the terminating nul and then do the bounds checking. Many projects
need this kind of functionality, so it gets reimplemented all the
time.
This commit adds some replacement functions that convert a string to a
signed or unsigned number that also follows the usual way of error
reporting - returning FALSE on failure and filling an error output
parameter.
The test_stdio_wrappers() test will spuriously fail if the mkdir-test
directory already exists and is non-empty, which can happen if a
previous test run has failed and left a coredump file in the directory.
Tighten up the error checking around the pre-test rmdir() call to catch
this failure.

GDateTime does overflow checks to see if the timestamp being passed in
is too big to be represented. However, it only does those after
converting from a timestamp to an interval, which involves some
multiplications and additions — and hence can overflow, and cause the
later bounds check to erroneously succeed. This results in a non-NULL
GDateTime being returned which represents completely the wrong date.
Fix the overflow checks (do them earlier) and add some unit tests.

There are a few places where commit 18a33f72 replaced valid (nullable)
(optional) annotations with just (optional). That has a different
meaning.
(nullable) (optional) can only be applied to gpointer* parameters, and
means that both the gpointer* and returned gpointer can be NULL. i.e.
The caller can pass in NULL to ignore the return value; and the returned
value can be NULL.
(optional) can be applied to anything* parameters, and means that the

Reformatted the docs for G_VARIANT_TYPE_UINT64 to avoid having a

that as a first element of the numbered list. The number being that
big probably makes gtk-doc to treat it as 1.

Temporarily increase the ref count of a GSource to 1 while calling its
finalize() callback, so that the finalize() implementation can call
GSource methods (like g_source_set_ready_time()) without causing
critical warnings. It’s safe to call those methods at this point, as the
source has been destroyed, but nothing has been freed.
This is an indirect way of fixing a race between GCancellable and
GCancellableSource, whereby the GCancellable::cancelled callback for the
GCancellableSource is not disconnected until the GCancellableSource’s
finalize() function is called. Previously, this meant there was a window
in which the GCancellableSource’s ref count was 0, but the ::cancelled
callback was still connected, and could legitimately be called as a
result of another thread calling g_cancellable_cancel() on the
GCancellable. The callback calls g_source_set_ready_time() on the
GSource, and there’s no thread-safe way of checking whether the GSource
has been destroyed. Instead, we have to change GSource so its ref count
is only decremented to 0 inside the locked section in
g_source_unref_internal() *after* the finalize() function has been
called, and hence after the GCancellable::cancelled callback has been
disconnected. The use of g_cancellable_disconnect() ensures that the
callback disconnection is thread safe.

Since commit e4ee307 ("Do not wake up main loop if change is from same
thread", bug 761102), GMainContext uses context->owner to decide if the
event loop is being run in the current thread. However, what really
matters is the phase in the prepare/query/poll/check/dispatch sequence.
Wakeups are only needed between the end of prepare and the end of poll,
and then only if prepare found that no sources were ready.
There is no need to take threads into account, because prepare, check
and all callers of conditional_wakeup all look at the new need_wakeup
flag inside LOCK_CONTEXT/UNLOCK_CONTEXT.
With this change, g_main_context_is_owner and g_main_context_wait are
the only functions for which acquire/release matters, just like before
commit e4ee307.

If encoding with small chunks such that the call to
g_base64_encode_close() has to deal with 0 < x < 24 bits of remaining
state, the encoding code would not correctly use zeroes to pad out the
state — it would use left-over state from an earlier iteration in the
encoding process.
This resulted in invalid base-64 encodings.

too.

now that it is public we should make the API more generic, allowing

the function is called with a string that has \0 in the middle
or for chunks of a strings that are not nul terminated.

Signed integer overflow is undefined behaviour, which the undefined

Previously, if the compiler had implemented this in the obvious way

(2**32 + 42) as valid IP addresses, by treating that octet as though

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.

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
