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.

On Unix platforms, wait() and friends yield an integer that encodes
how the process exited. Confusingly, this is usually not the same as
the integer passed to exit() or returned from main(): conceptually it's
an integer encoding of this tagged union:
enum { EXITED, SIGNALLED, ... } tag;
union {
int exit_status; /* if EXITED */
struct {
int terminating_signal;
bool core_dumped;
} terminating_signal; /* if SIGNALLED */
...
} detail;
Meanwhile, on Windows, wait statuses and exit statuses are
interchangeable.
I find that it's clearer what is going on if we are consistent about
referring to the result of wait() as a "wait status", and the value
passed to exit() as an "exit status".
GSubprocess already gets this right: g_subprocess_get_status() returns
the wait status, while g_subprocess_get_exit_status() genuinely returns
the exit status. However, the GSpawn family of APIs has tended to
conflate the two.
Confusingly, g_spawn_check_exit_status() has always checked a wait
status, and it would not be correct to pass an exit status to it; so
let's deprecate it in favour of g_spawn_check_wait_status(), which
does the same thing that g_spawn_check_exit_status() always did.
Code that needs backwards-compatibility with older GLib can use:
#if !GLIB_CHECK_VERSION(2, 69, 0)
#define g_spawn_check_wait_status(x) (g_spawn_check_exit_status (x))
#endif

This works in the same way as g_variant_take_ref(), and for the same
reason.

Closes#1112
This adds g_tls_connection_get_protocol_version(),
g_tls_connection_get_ciphersuite_name(), and DTLS variants. This will
allow populating TLS connection information in the WebKit web inspector.
This is WIP because we found it's not quite possibly to implement
correctly with GnuTLS. See glib-networking!151.
This changeset exposes
* `not-valid-before`
* `not-valid-after`
* `subject-name`
* `issuer-name`
on GTlsCertificate provided by the underlying TLS Backend.
In order to make use of these changes,
see the related [glib-networking MR][glib-networking].
This change aims to help populate more of the [`Certificate`][wk-cert]
info in the WebKit Inspector Protocol on Linux.
This changeset stems from work in Microsoft Playwright to [add more info
into its HAR capture][pw] generated from the Inspector Protocol events
and will bring feature parity across WebKit platforms.

Because sometimes you don't want a lone "%s", and you don't
want the compiler yelling at you about format strings that
don't have any format in them.
Closes#663
It is cleaner to define glib_typeof() in a header included after
gversionmacros.h so we can use GLIB_VERSION_MIN_REQUIRED directly
instead of doing it everywhere glib_typeof() is used.
This allows introspection to properly handle them as GPatternSpec
methods, as per this deprecate g_pattern_match() and
g_pattern_match_string() functions.
Fall back to compiler version checks only when `__has_attribute()` is not
available.
clang-cl doesn't define `__GNU__`, but still accepts attributes. This change
gets rid of a lot of warnings when building GLib with clang-cl. For GCC and
non-cl Clang nothing should change.
This is basically glnx_steal_fd() from libglnx. We already had two
private implementations of it in GLib.

This adds g_string_replace(), a function that replaces instances of one string
with another in a GString. It allows the caller to specify the maximum number
of replacements to perform, and returns the number of replacements performed
to the caller.
Fixes: #225
This will replace the existing `g_memdup()` function, which has an
unavoidable security flaw of taking its `byte_size` argument as a
`guint` rather than as a `gsize`. Most callers will expect it to be a
`gsize`, and may pass in large values which could silently be truncated,
resulting in an undersize allocation compared to what the caller
expects.
This could lead to a classic buffer overflow vulnerability for many
callers of `g_memdup()`.
`g_memdup2()`, in comparison, takes its `byte_size` as a `gsize`.

That changes the return type of functions like g_object_ref() that can
break C++ applications like Webkit. Note that it is not an ABI break.
It must thus be opt-in the same way we did when adding this to
g_object_ref() for GNU C compilers in the first place. Unfortunately it
cannot be done directly in gmacros.h because GLIB_VERSION_2_68 is not
defined there, and gversionmacros.h cannot be included there because
there is some strict ordering in which those headers must be included.
This means that applications that does not define
GLIB_VERSION_MIN_REQUIRED will still get an API break, so we encourage
them to declare their minimum requirement to avoir such issues in the
future too.
I found myself wanting to know the test that is currently being run,
where e.g. __func__ would be inconvenient to use, because e.g. the place
the string was needed was not in the test case function. Using __func__
also relies on the test function itself containing the whole path, while
loosing the "/" information that is part of the test path.
These two APIs are useful to publish an object which path content is not
controlled (e.g. dynamically built or coming from external source).

Even if the modules in the given directory never get chosen to be used,
loading arbitrary code from a user-provided directory is not safe when
running as setuid, as the process’ environment comes from an untrusted
source.
Also ignore `GIO_EXTRA_MODULES`.
