Instead of using gtk_css_provider_get_default(), add a
static GtkCssProvider and fetch it instead. Creating
GtkCssProviders consume a bit more memory, so keeping
a single one alive is slightly more memory saving.
It relied on indices in arrays determining tile direction and
non-obvious bitmask logic to translate to _GTK_EDGE_CONSTRAINTS. Change
this to explicitly named edge constraints, and clear translation methods
that converts between mutters and GTK+s edge constraint formats.
An unnecessary memory optimization, storing the tile mode as a 2 bit
unsigned integer, was used. While saving a few bytes, it made debugging
harder. Remove the useless byte packing.
If texture allocation fails (e.g. on an old GPU with size limit 2048)
then `update_fbo` would return `FALSE` but leaves `priv->offscreen`
as non-NULL. So the next paint will try to use the offscreen with a
`NULL` texture and crashes. The solution is simply to ensure that
`priv->offscreen` is NULL if there is no `priv->texture`, so the default
(non-offscreen) paint path gets used instead.

If texture allocation fails (e.g. on an old GPU with size limit 2048)
then `cogl_texture_new_with_size` was trying to use the same CoglError
twice. The second time was after it had already been freed.

This will allow CoglFramebuffer and its implementations to be exposed
to GJS and other language bindings. This is a necessary part of the
bigger work to make framebuffer management explicit.
CoglOffscreen is effectively a CoglFramebuffer, but it isn't being marked as
such by the GType machinery. This makes it impossible for introspection to
correctly set this class up.
Fix that by adding a COGL_GTYPE_IMPLEMENT_INTERFACE() code into the declaration
of CoglOffscreen. This does not have any functional changes though.
This adds compilation testing using meson on the gitlab instance. It
uses a prebuild image built, described in .gitlab-ci/Dockerfile, based
on Fedora 29.
The image is build and published by running:
cd .gitlab-ci/
docker build -t registry.gitlab.gnome.org/gnome/mutter/master:v1 .
docker push registry.gitlab.gnome.org/gnome/mutter/master:v1
Resolves: https://gitlab.gnome.org/GNOME/mutter/merge_requests/132
Meson uses the 'dependencies' field to determine and
parallelize build steps, but that isn't entirely true
with 'link_with'; this might cause a race condition
when generating header files while trying to build
them.
Fix that by only using 'dependencies' instead of 'link_with'.
gudev and libudev might have different versions, and
since 361bf847 we require gudev >= 232 to be able to
use g_autoptr with gudev types.
Since the previous commit, however, the meson build
was using the same version for libudev and gudev.
Fix that by requiring different versions for gudev
(>= 232) and libudev (>= 228).
Continuous' latest udev version is 228, and that is
not going to change too soon. Since we do not depend
on udev 232 specific features or bugfixes, just lower
the minimum version and make Continouos happy.
This commit adds meson build support to mutter. It takes a step away
from the three separate code bases with three different autotools setups
into a single meson build system. There are still places that can be
unified better, for example by removing various "config.h" style files
from cogl and clutter, centralizing debug C flags and other configurable
macros, and similar artifacts that are there only because they were once
separate code bases.
There are some differences between the autotools setup and the new
meson. Here are a few:
The meson setup doesn't generate wrapper scripts for various cogl and
clutter test cases. What these tests did was more or less generate a
tiny script that called an executable with a test name as the argument.
To run particular tests, just run the test executable with the name of
the test as the argument.
The meson setup doesn't install test files anymore. The autotools test
suite was designed towards working with installed tests, but it didn't
really still, and now with meson, it doesn't install anything at all,
but instead makes sure that everything runs with the uninstalled input
files, binaries and libraries when running the test suite. Installable
tests may come later.
Tests from cogl, clutter and mutter are run on 'meson test'. In
autotools, only cogl and clutter tests were run on 'make check'.
The touch handling code uses evdev API, thus will not work on other
backends. Thus, put touch handling code behind runtime backend checks
and only include the code when native backend support is enabled.
Install include files in
$prefix/include/mutter-$apiversion/[clutter,cogl,...,meta]/, and
datafiles in /usr/share/mutter-$apiversion/.... We still would conflict
e.g. given that our gettext name is "mutter", and how keybindings are
installed, but it's a step in the right direction.
This is the filename convention you get when you define a shared module
in meson, and since there is no particular reason to not include the
"lib" prefix, lets make it easier to port it over. While at it,
de-duplicate the retrieval of the plugin name.
It'll be installed in the meta/ directory, so put the template files in
the corresponding directory in the tarball. This will also simplify the
port to meson.
While leaving the runtime checks in place, requiring xrandr 1.5 at build
time allows us to remove some seemingly unnecessary conditional
inclusion of functionality.
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
