As per meson spec, returncode() produces unspecified data if
compiled() == false. Check compiled() first to avoid relying
upon unspecified data.
In addition, muon -- an implemetation of meson written in C goes
further and forbids returning unspecified data. This is a good
decision, but also makes it harder to support applications which
wrongly use meson API. Therefore, application needs to be fixed.
It is not only shorter than `not meson.is_cross_build() or
meson.has_exe_wrapper()` but also handle the case of cross compiling to
a compatible arch such as building for i386 on an amd64.
Move msvc warnings in meson.build file from line 24 to line 469 to group
them next to gcc/clang warnings. So it is easier to see warnings flags
for all platforms at once.
This reverts commit 4a4d9eb662.
It seems to cause build failures with `VsDevCmd.bat` 2022:
```
..\meson.build:2274:0: ERROR: Command "C:\Program Files\Meson\meson.exe runpython --version" failed with status 2.
```
Revert it for now until this can be fixed in Meson.

It can be treated like any other command, we don't need a full blown
module capable of building extensions just to get an ExternalProgram
executable that can be used to run scripts.
Since find_program has a builtin kwarg for requiring a given version, we
can avoid manually coding some checks and emitting a custom error.
When working with storage (especially GInputStream or GOutputStream) it
is preferred to use page-aligned buffers so that the operating system
can do page-mapping tricks as the operation passes through the kernel.
Another use case is allocating memory used for vectorised operations,
which must be aligned to specific boundaries.
POSIX and Windows, as well as the C11 specification, provide this kind
of allocator functions, and GLib already makes use of it inside GSlice.
It would be convenient to have a public, portable wrapper that other
projects can use.
Fixes: #2574
Glib cannot be built statically on Windows because glib, gobject and gio
modules need to perform specific initialization when DLL are loaded and
cleanup when unloaded. Those initializations and cleanups are performed
using the DllMain function which is not called with static builds.
Issue is known for a while and solutions were already proposed but never
merged (see: https://gitlab.gnome.org/GNOME/glib/-/issues/692). Last
patch is from version 2.36.x and since then the
"constructor/destructor" mechanism has been implemented and used in
other part of the system.
This patch takes back the old idea and updates it to the last version of
glib to allow static compilation on Windows.
WARNING: because DllMain doesn't exist anymore in static compilation
mode, there is no easy way of knowing when a Windows thread finishes.
This patch implements a workaround for glib threads created by calling
g_thread_new(), so all glib threads created through glib API will behave
exactly the same way in static and dynamic compilation modes.
Unfortunately, Windows threads created by using CreateThread() or
_beginthread/ex() will not work with glib TLS functions. If users need
absolutely to use a thread NOT created with glib API under Windows and
in static compilation mode, they should not use glib functions within
their thread or they may encounter memory leaks when the thread finishes.
This should not be an issue as users should use exclusively the glib API
to manipulate threads in order to be cross-platform compatible and this
would be very unlikely and cumbersome that they may mix up Windows native
threads API with glib one.
Closes#692
This code was skipping fsync on BTRFS because of an old guarantee about
the overwrite-by-rename behavior that no longer holds true. This has
been confirmed by the BTRFS developers to no longer be guaranteed since
Kernel 3.17 (August 2014), but it was guaranteed when this optimization
was first introduced in 2010.
This could result in empty files after crashes in applications using
g_file_set_contents(). Most prominently this might have been the cause
of dconf settings getting lost on BTRFS after crashes due to the
frequency with which such writes can happen in dconf.

Using ld_flags would work, but that does not propagate ldflags to users
of glib. Meson's dependency() call will propagate apple framework
dependencies to downstream users.
Previously they were only passed to the C compiler, which meant disabled
warnings were still emitted when (for example) including C headers from
C++ and ObjC files.

It is exactly the same wrap as the one in WrapDB but with a different
name. That fix error when multiple projects uses pcre and they don't
have the same wrap name:
meson.build:1:0: ERROR: Multiple wrap files provide 'libpcre' dependency: pcre.wrap and libpcre.wrap
This is what’s available in the new Debian Stable, so we can expect it
to be available pretty much everywhere.
Subsequent commits will clean up old workarounds.

Include the correct system headers for each test that meson performs.
This allows system capabilities to be detected correctly even if
implicit declaration of functions is considered an error.
This should maintain equivalent functionality, apart from that now you
have to pass `--force-fallback-for libpcre` to `meson configure` in
order to use the subproject; rather than specifying
`-Dinternal_pcre=true` to use the internal copy.
This also fixes#642, as the wrapdb copy of libpcre is version 8.37.

If libintl is built statically on macOS, linking it requires passing
"-framework CoreFoundation" to satisfy symbol dependencies. Use the

Make msvc_recommended_pragmas.h work better with clang-cl so that we can
use that to eliminate some warnings that are emitted as it also consumes
Microsoft compiler and SDK headers.
Also, for GLib builds, force-include msvc_recommended_pragmas.h for
clang-cl builds as well, as it becomes usable and useful there.
Fixes issue #2357.
Functions (_g_get_time_charset and _g_get_ctype_charset) to get LC_TIME and LC_CTYPE charset
by using nl_langinfo with _NL_TIME_CODESET and CODESET).
Another functions (_g_locale_time_to_utf8 and _g_locale_ctype_to_utf8) which uses thel and format
the input string accordingly.
Add new test cases with mixing UTF8 and non UTF8 LC_TIME along with UTF8
and non UTF8 LC_MESSAGES.
