Interpret the value "help" for environment variables that
are passed to _g_io_module_get_default(), and print the
names and priorities of available extensions.
This lets users explore what is available, and can be helpful
in figuring out why a certain extension was chosen as default.
It is similar in spirit to what we already do with environment
variables like G_DEBUG.
They’re out of date. Probably best to leave the document unsigned, since
it’s supposed to be endorsed by all the GLib maintainers.

This is useful for debugging in many situations. It’ll be printed with
G_MESSAGES_DEBUG=GLib-GIO or G_MESSAGES_DEBUG=all.
Mostly I need it for debugging the default GNetworkMonitor, but it will
work for all GIO module implementations.

When we are in a sandboxed situation, bump the priority
of the keyfile settings backend above the dconf one,
so we use a keyfile inside the sandbox instead of requiring
holes in the sandbox for dconf.
Stacked databases and locks are dconf features that allow
management software like Fleet Commander to set system-wide
defaults and overrides centrally for applications.
This patch adds minimal support for the same to the keyfile
backend. We look for a keyfile named 'defaults' and a
lock-list named 'locks'.
Suitable files can be produced from a dconf database with
dconf dump and dconf list-locks, respectively.
The default location for these files is /etc/glib-2.0/settings/.
For test purposes, this can be overwritten with the
GSETTINGS_DEFAULTS_DIR environment variable.
Writes always go to the per-user keyfile.
Make it possible to instantiate a keyfile settings backend
without specifying parameters, by turning the arguments to
the new() function into construct-only properties. If no
filename is specified, default to
$XDG_CONFIG_HOME/glib-2.0/settings/keyfile
Rather than prefixing unsigned numbers with unary minus operators and
expecting the implicit cast to carry the correct value through, add an
explicit cast to a signed type before the unary minus is applied.
In all four cases, an overflow check has already been done.

It needs investigating and fixing properly, but let’s not let it disrupt
the CI in the meantime.

There's a race here, as revealed by Debian's buildds.
We call g_dbus_proxy_new() to create a proxy for the test server, with
callback proxy_ready() Then we call g_spawn_command_line_async() to
start the test server, and then start the main loop.
proxy_ready() assumes that the test server hasn't been started when it
is called. But there is no guarantee that these asynchronous operations
involving spawning a process won't happen in a different order that mean
the bus name *does* have an owner.
What we can do is move starting the server inside of proxy_ready(), so
we know that the test server isn't started until after the proxy is
created. We also add an assertion to check that it is indeed not running
before we execute it.
Rather than storing it as an invalid value in last_position, store it as
a separate boolean.
This introduces no functional changes, but should fix some warnings from
MSVC.

The subprocess needs to access the test_log_fd. If the file descriptors
are not left open, functions such as g_test_message may stomp on file
descriptors open by the subprocess and cause bad behavior of the test.
(Tweaked by Philip Withnall <bugzilla@tecnocode.co.uk> to fix review
comments.)
If we can't find the mount point for target or tmp (as currently
happens on Launchpad autobuilders, and perhaps relatedly, on a
development system that uses btrfs), that's probably not great but is
not really the point of this test.

In a minimal autobuilder environment, this test could conceivably be
the first thing to refer to ~/.local.
Modified by Iain Lane <laney@debian.org>: Don't try to create ~/.local
from tests, but skip if it doesn't exist.

In C++ we can use nullptr to ensure g_assert_[non]null() is only called
with pointers. This will introduce build failures in tests that would
have previously compiled, but only in C++, and only for code that
misused these macros. Code using the macros properly will be fine.
This change caught a couple bugs in WebKit's API tests, where I had
accidentally used these functions improperly. E.g. this is now a build
failure in C++:
g_assert_null(webkit_context_menu_get_n_items(menu)); /* Oops! */
Either I wanted to use cmpuint there, or I wanted to use
webkit_context_menu_get_items() to receive a GList* instead.
Another example that will no longer build in C++:
g_assert_null(0); /* Contrived, but 0 is not a pointer! */
So long, and thanks for everything. We’re a Meson-only shop now.
glib-2-58 will remain the last stable GLib release series which is
buildable using autotools.
We continue to install autoconf macros for autotools-using projects
which depend on GLib; they are stable API.

The behaviour of the Meson build has changed a little vs what we did in
autotools. In autotools, --enable-debug was a tristate (yes, no,
undefined), with all three options resulting in different macro
definitions.
In Meson, we have a bistate of --buildtype={debug,debugoptimized} vs
--buildtype=(anything else). There is no way to automatically define
G_DISABLE_ASSERT or G_DISABLE_CHECKS while building GLib — you need to
define them in your CPPFLAGS in your environment instead.

Drop mentions of autotools. In particular, update the list of configure
options to reflect what’s available in the Meson build.
Further work is needed as a follow-up to improve our handling of (what
was formerly) the --enable-debug option.
