Change the GETTEXT_POISON compile-time + runtime GIT_GETTEXT_POISON test parameter to only be a GIT_TEST_GETTEXT_POISON=<non-empty?> runtime parameter, to be consistent with other parameters documented in "Running tests with special setups" in t/README. When I added GETTEXT_POISON in bb946bba76 ("i18n: add GETTEXT_POISON to simulate unfriendly translator", 2011-02-22) I was concerned with ensuring that the _() function would get constant folded if NO_GETTEXT was defined, and likewise that GETTEXT_POISON would be compiled out unless it was defined. But as the benchmark in my [1] shows doing a one-off runtime getenv("GIT_TEST_[...]") is trivial, and since GETTEXT_POISON was originally added the GIT_TEST_* env variables have become the common idiom for turning on special test setups. So change GETTEXT_POISON to work the same way. Now the GETTEXT_POISON=YesPlease compile-time option is gone, and running the tests with GIT_TEST_GETTEXT_POISON=[YesPlease|] can be toggled on/off without recompiling. This allows for conditionally amending tests to test with/without poison, similar to what 859fdc0c3c ("commit-graph: define GIT_TEST_COMMIT_GRAPH", 2018-08-29) did for GIT_TEST_COMMIT_GRAPH. Do some of that, now we e.g. always run the t0205-gettext-poison.sh test. I did enough there to remove the GETTEXT_POISON prerequisite, but its inverse C_LOCALE_OUTPUT is still around, and surely some tests using it can be converted to e.g. always set GIT_TEST_GETTEXT_POISON=. Notes on the implementation: * We still compile a dedicated GETTEXT_POISON build in Travis CI. Perhaps this should be revisited and integrated into the "linux-gcc" build, see ae59a4e44f ("travis: run tests with GIT_TEST_SPLIT_INDEX", 2018-01-07) for prior art in that area. Then again maybe not, see [2]. * We now skip a test in t0000-basic.sh under GIT_TEST_GETTEXT_POISON=YesPlease that wasn't skipped before. This test relies on C locale output, but due to an edge case in how the previous implementation of GETTEXT_POISON worked (reading it from GIT-BUILD-OPTIONS) wasn't enabling poison correctly. Now it does, and needs to be skipped. * The getenv() function is not reentrant, so out of paranoia about code of the form: printf(_("%s"), getenv("some-env")); call use_gettext_poison() in our early setup in git_setup_gettext() so we populate the "poison_requested" variable in a codepath that's won't suffer from that race condition. * We error out in the Makefile if you're still saying GETTEXT_POISON=YesPlease to prompt users to change their invocation. * We should not print out poisoned messages during the test initialization itself to keep it more readable, so the test library hides the variable if set in $GIT_TEST_GETTEXT_POISON_ORIG during setup. See [3]. See also [4] for more on the motivation behind this patch, and the history of the GETTEXT_POISON facility. 1. https://public-inbox.org/git/871s8gd32p.fsf@evledraar.gmail.com/ 2. https://public-inbox.org/git/20181102163725.GY30222@szeder.dev/ 3. https://public-inbox.org/git/20181022202241.18629-2-szeder.dev@gmail.com/ 4. https://public-inbox.org/git/878t2pd6yu.fsf@evledraar.gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> --- .travis.yml | 2 +- Makefile | 8 +------- ci/lib-travisci.sh | 4 ++-- gettext.c | 11 +++++++---- gettext.h | 9 +++------ git-sh-i18n.sh | 2 +- po/README | 13 ++++--------- t/README | 6 ++++++ t/lib-gettext.sh | 2 +- t/t0000-basic.sh | 2 +- t/t0205-gettext-poison.sh | 8 +++++--- t/t3406-rebase-message.sh | 2 +- t/t7201-co.sh | 6 +++--- t/t9902-completion.sh | 3 ++- t/test-lib-functions.sh | 8 ++++---- t/test-lib.sh | 22 +++++++++++++++++----- 16 files changed, 59 insertions(+), 49 deletions(-)
