My web design skills are terrible, but it's better than nothing; I'm
sure this will lead to somebody filing a merge request to make the
test report look a lot better.
While we're at it, let's include the reftest images inside the report
itself, so we don't have to hunt them down.
The JUnit cover report is useful, but only up to a point; for instance,
it's not used unless it's part of a merge request. This means you don't
get a report if you're pushing to a branch that does not have an MR open.
With a simple Python script and some minimal templating, we can generate
an HTML report from the "I Can't Believe it's not JSON™" log that Meson
produces, and keep it as a CI artifact.
GitLab's CI will bail out at the first failure, which means the
JSON-to-JUnit conversion script won't run unless it's part of the same
script that we run for building an testing.
There where some problems (??) with ccache not detecting changes during meson
checks. Setting CCACHE_DISABLE during the meson execution makes ccache not use
the cache and pass things directly to the compiler.
Turns out that GCC errors out when building the GLib test suite, as it
now checks for overflows in allocator functions, and we're testing for
those.
This would not be an issue for GTK, but since we're building GLib as a
subproject, we get failures for those as well.
Until we can find out how to disable errors for subprojects, or fix the
GLib test suite not to trip up warnings in GCC, we're going to live
without compiler warnings treated as errors for a while.
xvfb doesn't like C.utf8 and returns XLocaleNotSupported.
While (afaik) C.utf8 and C.UTF.8 should be the same thing, and the former
is returned by locale -a on Fedora, switch to C.UTF-8 to make xvfb happy.
This makes gtk+:gdk tests pass.
