The latter was discussed on IRC last year but I don't know if anyone has tried to investigate this yet. Nov 24 11:36:53 <groug> th_huth, Hi. FYI it seems that the meson conversion kinda broke 'make check SPEED=slow'. Test programs aren't passed '-m slow' Nov 24 11:51:42 <f4bug> th_huth: do you know who uses/tests SPEED=slow? Nov 24 11:52:03 <f4bug> th_huth: I thought this was a block-related feature Nov 24 11:52:44 <groug> f4bug, it is supposedly used by gitlab CI Nov 24 11:52:59 <groug> .gitlab-ci.yml: MAKE_CHECK_ARGS: check-qtest SPEED=slow Nov 24 12:50:53 <th_huth> groug, I'm also running make check SPEED=slow manually sometimes ... I guess that got lost in the conversion to ninja ... bonzini, did you ever try? Nov 24 12:51:03 <bonzini> no it shouldn't Nov 24 12:51:21 <th_huth> let me check... Nov 24 12:51:40 <bonzini> ah, the tests are chosen correctly but -m slow is lost Nov 24 12:52:02 <groug> yes that's what I see Nov 24 12:54:04 <groug> bonzini, missing bits in scripts/mtest2make.py ? Nov 24 12:54:28 <bonzini> groug: sort of, but assuming that all executables support -m slow wouldn't work Cc'ing Thomas and Paolo for additional details. > Best regards, > Christian Schoenebeck > >
