As part of my powerpc efforts I built glib on my way to building ...
something. This is on an iBook G4 with the original 4200 RPM drive from
~15 years ago, so old hardware.
In glib-2.68 test_timeout and test_timeout_slow are set to 60 and 180
respectively. I initially merged the increase-test-timeout changes to
apply to all architectures, and then changed the time to 240 before
changing it to 1800 during my testing. I've attached the build log from
that round.
As I understand it, the tests which are are tagged '+slow' get the
test_timeout_slow property, with the test taking the longest on that
machine was glib:glib+slow / gvariant, at 65 seconds. By comparison, on
my Ryzen 3900XT machine it took 2.58 seconds. I figured even at double
that time it still fell within the 180 seconds given by default in the
test suite so it was likely safe to remove the substitution entirely.
I don't have other suitably slow hardware to test on, but I am building
it on my aarch64 board too, so I should be able to say in a day or two
if it works there.
