I'll update it to keep the hardcoded 10 jobs in place for now for the other pipelines. Trying to do too many things at once is only going to make it harder to get this landed, doubly so when you have no easy way to verify what you're doing :) > > - We now always pass `--state=failed,slow,save` via GIT_PROVE_OPTS. > > It doesn't hurt on platforms where we don't persist the state, so > > this further reduces boilerplate. > > > > - When running on Windows systems we set `--no-chain-lint` and > > `--no-bin-wrappers`.

The reason why I chose to use it is that there was indeed a bug already with the order of exports and modification of the vars after the export. So with that in mind it made sense to me to adapt it accordingly. > > Signed-off-by: Patrick Steinhardt <ps@xxxxxx> > > --- > > ci/lib.sh | 24 ++++++++++++++---------- > > 1 file changed, 14 insertions(+), 10 deletions(-) > > > > diff --git a/ci/lib.sh b/ci/lib.sh > > index 9ffdf743903..c7a716a6e3f 100755 > > --- a/ci/lib.sh > > +++ b/ci/lib.sh > > @@ -175,11 +175,7 @@ then > > # among *all* phases) > > cache_dir="$HOME/test-cache/$SYSTEM_PHASENAME" > > - export GIT_PROVE_OPTS="--timer --jobs 10 --state=failed,slow,save" > > - export GIT_TEST_OPTS="--verbose-log -x --write-junit-xml" > > - MAKEFLAGS="$MAKEFLAGS --jobs=10" > > - test windows_nt != "$CI_OS_NAME" || > > - GIT_TEST_OPTS="--no-chain-lint --no-bin-wrappers $GIT_TEST_OPTS" > > + GIT_TEST_OPTS="--write-junit-xml" > > elif test true = "$GITHUB_ACTIONS" > > then > > CI_TYPE=github-actions > > @@ -198,17 +194,25 @@ then > > cache_dir="$HOME/none" > > - export GIT_PROVE_OPTS="--timer --jobs 10" > > - export GIT_TEST_OPTS="--verbose-log -x --github-workflow-markup" > > - MAKEFLAGS="$MAKEFLAGS --jobs=10" > > - test windows != "$CI_OS_NAME" || > > - GIT_TEST_OPTS="--no-chain-lint --no-bin-wrappers $GIT_TEST_OPTS" > > + GIT_TEST_OPTS="--github-workflow-markup" > > else > > echo "Could not identify CI type" >&2 > > env >&2 > > exit 1 > > fi > > +MAKEFLAGS="$MAKEFLAGS --jobs=$(nproc)" > > +GIT_PROVE_OPTS="--timer --jobs $(nproc) --state=failed,slow,save" > > + > > +GIT_TEST_OPTS="$GIT_TEST_OPTS --verbose-log -x" > > +if test windows = "$CI_OS_NAME" > > +then > > + GIT_TEST_OPTS="$GIT_TEST_OPTS --no-chain-lint --no-bin-wrappers" > > +fi > > > > +export GIT_TEST_OPTS > > +export GIT_PROVE_OPTS > > I was wondering why we don't export MAKEFLAGS here but it is exported > earlier on before we set it.

I'll adapt it in the same way. Patrick
