Closes: #15807 by preloading API-related libraries for 3P plug-ins sake.
This will only work if the .appimage is run normally (without extract), because
when extracted its APPDIR can be placed on dirs with spaces unsupported by LD.
It also requires plug-ins to be built with the Debian used for the AppImage.
But there is nothing new under the sun, this rule is valid for all packages.
This reverts commit bc095d5c83.
Sandboxing XDG_DATA_DIRS, while can fix the crash due to share/mime,
on the other hand makes impossible to call share/applications
associated with such mimes on host.
So, since we bumped the AppImage to Debian Trixie so the Glib
crash due to mime is gone, we can (and should) revert the
wrong sandboxing without problems.
Fixes: #13001#13106#13492#13647#14779
AppImage jobs are now built with Trixie to adress #13001 and many others.
To have two Debian versions with less complexity possible, I needed to:
- Revert the prevalence of the AppImage CI (now nonreloc comes first);
- Revert the use of Clang on Debian (also to save 120MB from registry,
since we now have 4 Docker images, each one with its own STEP cache!).
In short, .gitlab-ci.yml will look more like before I changing it a lot.
Closes#13001
XDG_DATA_DIRS is a variable used by many deps (e.g. glib) to
find runtime data. So, let's point XDG_DATA_DIRS to the
appimage bundle so prevent unexpected data from the host.
This patch ports our MyPaint code to use the
MyPaintSurface2 API, allowing us to support
version 2 MyPaint Brushes correctly.
The API update lets us take into account
the zoom factor and rotation of the canvas
when drawing. It also adds a "Gain" option
to the GUI in order to control the strength
of the input's pressure (tablet or mouse).
As a caveat, this patch does not yet
implement spectral/pigment blending.
Seems it was used at runtime in the past but that is
not the case anymore. Indeed, it started to be bundled in
af79bbe028 due to an
error: before the Windows bundling unification the
crossbuilds "script" on .yml bundled all the 'share' dir.
Closes: #12929
This normalizes argv0, making the AppImage debuggable by gdb etc.
From now, the AppImage can't be run in pre-Bookworm (glibc < 2.36)
distros, but that use case was never officialy supported anyway.
We can't guarantee that the .so modules pointed by GIO_EXTRA_MODULES will
link properly to the bundled libc and other bundled deps in the AppImage.
So, by making our AppImage ignore that var we avoid errors on terminal due
to linking mismatch (e.g. on NixOS which sets that var by default).
