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).

The static analyser (correctly) considers a type check to fail if the
variable is NULL. In this case, the address must be non-NULL as no error
was thrown by g_socket_connection_get_remote_address(), but the static
analyser doesn’t know this.
Add a non-NULL assertion anyway, both to shut the analyser up, and
because it’s good extra testing.

These prevent some false positives from the static analyser which are
caused by it not inspecting the invariants of
g_subprocess_communicate[_utf8]_finish() (i.e. that stdout and
stdout_str will always be set unless an error was returned).
They’re also good testing anyway.

If the initial part of the header (‘MIME-TreeMagic’) is valid, but the
following line does not start with ‘[’ (i.e. is not a valid section
line), insert_matchlet() will be called with a NULL match pointer, and
will crash with a NULL pointer dereference.
Fix this by bailing out if a valid section line isn’t encountered before
the first insert_matchlet() call (i.e. between the header line and the
first data line).
Note that this has not been tested against a real treemagic file; the
fix is purely theoretical.

In the case that (n_fds == 0 && fds == NULL), memcpy() would be called
against a NULL src pointer. Even though the number of bytes to copy is
0, avoid the possibility of a crash by only calling if fds is non-NULL.

The static analyser will check dynamic type assertions and assume that
if they fail, the variable can either have the wrong type, or be NULL
(which is correct). The analyser doesn’t know that other constraints in
the API ensure the variable is non-NULL.
Add a non-null assertion to help the static analyser and shut it up in
this case.

This can happen if the hash table lookup for ‘noncefile’ fails, and
hence the first ‘goto out’ is hit, at which point resolver is still
NULL.

Be a little bit more careful in regards to initializing a primitive type
variable before passing it by reference, as it could have random stuff
in the variable's address depending on the CRT, such as MSVCR110.DLL,
causing random, invalid stuff being written in that address.
This will fix this test when built with Visual Studio 2012.

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).

Warning C4819 in Visual Studio builds indicates an issue of Visual Studio
2005 and later running on East Asian locales of Windows, which likely
results in broken builds of GLib, Pango, GTK+, and possibly other GNOME
projects such as Cogl and Clutter (and is also an issue when building other
projects like QT and Firefox).
Treat this warning as an error as a result when building GLib-based items
on Visual Studio, and tell people how to remedy this issue correctly.
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_OS #ifdefs are only available once glibconfig.h has been
evaluated ; that is, after including glib headers.
Move this block down so it gets correctly evaluated.
Make it possible to skip the terminal-launching test simply
by setting DISPLAY= . Previously, you had to unset DISPLAY,
which is a little more cumbersome.

One testcase was launching appinfo-test from a GAppInfo that
does not have a filename. In this case, the G_LAUNCHED_DESKTOP_FILE
envvar is not exported. Make appinfo-test deal with that, without
spewing warnings.

The actions test tests the GSimpleActionGroup API. Maybe this
should be moved to use GActionMap, but for now, just disable
the deprecations.
There was also one test that wasn't actually hooked up, so
do that as well.
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.

When the function in the test program is inlined, all bets are
off whether the detection will work correctly or not. Make it
harder for the compiler to play games on us by making the
function recursive.

This is the sole piece of code in GLib where we make use of the
stack growing direction. And this test proves that we have been
getting the direction wrong all these years...
The signals queued while notify is frozen are emitted in
reverse order, while omitting duplicates. The lack of documentation
for this was pointed out in

Most _list_schemas() uses were to check for the availability
of a particular schema. g_settings_schema_source_lookup() is
a better way to do this.
