That GPG vs --convert-graft-file thing really does have a bit of a fallout, doesn't it?

Well, in case of the GPG prereq there is an easy way: you could have just commented out that . "$TEST_DIRECTORY/lib-gpg.sh" line near the beginning of the test script. Just a single '#' character, it can't get much easier than that :) But yeah, this doesn't work with every prereq... > So I came up with a way, > and this patch reflects the cleaned-up version of that way. > > For convenience, the following two methods are now supported ways to > pretend that a prereq is not met: > > test_set_prereq !GPG > > and > > test_unset_prereq GPG I'm not sure this is the right way to do this. I wanted to run the whole test suite with all GPG tests skipped the other day. With this 'test_unset_prereq' I would have to modify all test scripts containing tests depending on the GPG prereq and add 'test_unset_prereq GPG', right? I rather modified 't/lib-gpg.sh', i.e. only a single file, instead of modifying the 13 test scripts that match the 'test_expect_[a-z]*[ ,]GPG[ ,]' regexp. I think we would be better served by an environment variable similar to $GIT_SKIP_TESTS, e.g. $GIT_SKIP_PREREQS, to list all the prereqs that should be skipped even if they were met. > Signed-off-by: Johannes Schindelin <johannes.schindelin@xxxxxx> > --- > Published-As: https://github.com/dscho/git/releases/tag/test-unset-prereq-v1 > Fetch-It-Via: git fetch https://github.com/dscho/git test-unset-prereq-v1 > t/test-lib-functions.sh | 14 +++++++++++++- > 1 file changed, 13 insertions(+), 1 deletion(-) Anyway, please add a bit of documentation with docstrings and/or in 't/README'. > > diff --git a/t/test-lib-functions.sh b/t/test-lib-functions.sh > index 7d620bf2a9a..76cd6630f29 100644 > --- a/t/test-lib-functions.sh > +++ b/t/test-lib-functions.sh > @@ -278,8 +278,20 @@ write_script () { > # The single parameter is the prerequisite tag (a simple word, in all > # capital letters by convention). > > +test_unset_prereq () { > + ! test_have_prereq "$1" || > + satisfied_prereq="${satisfied_prereq% $1 *} ${satisfied_prereq#* $1 }" > +} > + > test_set_prereq () { > - satisfied_prereq="$satisfied_prereq$1 " > + case "$1" in > + !*) > + test_unset_prereq "${1#!}" > + ;; > + *) > + satisfied_prereq="$satisfied_prereq$1 " > + ;; > + esac > } > satisfied_prereq=" " > lazily_testable_prereq= lazily_tested_prereq= > > base-commit: 1f1cddd558b54bb0ce19c8ace353fd07b758510d > -- > 2.17.0.windows.1.36.gdf4ca5fb72a >
