Unlike the other bindings (Lua, JS, Vala) where we only have a demo
plug-in, we actually have a bunch of interesting and useful Python
plug-ins.
Furthermore, we are running several Python scripts through GIMP during
our build (to generate a few images), so pygobject becomes a build
dependency anyway, even if it may not be a run dependency with
-Dpython=disabled.
This all becomes a bit confusing and in fact handling this case (of not
installing Python plug-ins) seems like an annoyance while we lose good
core plug-ins. So let's just make Python plug-ins mandatory. It's not
like Python is very controversial these days, and AFAWK, it is available
on every platform out there.
The original reason to skip these was because the new _list_ API were
introspected basically to a similar function signature, except with a
useless return value, at least in pygobject binding where the list size
was also returned.
Though it seems that in fact, only the docstring was wrong. The real
signature was apparently already the same.
See: https://gitlab.gnome.org/GNOME/pygobject/-/issues/352
Therefore since the _get_ naming is more consistent compared to other
existing function, let's re-integrate the _get_ functions for array of
items or images.
This basically reverts commit 15ec254148.
file plug-in testing.
The name and location of the xml results will be the same as for the
log file, but with the extension replaced by .xml.
Just some basic support is added which adds failed testcases when
a plug-in has a failure result, which should be the most common
case of failures.
Not all cases where we make errors in our test setup will generate
failed testcases yet, although they should show up in the number of
failures.
Disabled tests won't show up as skipped tests.
We also don't track time.
for gimp-tests.log
On Linux we may not have permission to create a log at our default
location, so we need to check for that.
First we should not init the log when our plug-in is asked for info.
Only create it when we actually run the import or export tests.
Second, try to catch the permission error and write a message either
in GIMP or in the terminal for non-interactive.
Copied over from the original separate work in:
https://gitlab.gnome.org/Wormnest/gimp-file-plugin-tests
After that further improved and changed and added more file format
tests.
Added meson.build files to integrate it in our build, but we do not
install it for releases.
