i18n: make GETTEXT_POISON a runtime option 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> Signed-off-by: Junio C Hamano <gitster@pobox.com>

travis-ci: build with GCC 4.8 as well C99 'for' loop initial declaration, i.e. 'for (int i = 0; i < n; i++)', is not allowed in Git's codebase yet, to maintain compatibility with some older compilers. Our Travis CI builds used to catch 'for' loop initial declarations, because the GETTEXT_POISON job has always built Git with the default 'cc', which in Travis CI's previous default Linux image (based on Ubuntu 14.04 Trusty) is GCC 4.8, and that GCC version errors out on this construct (not only with DEVELOPER=1, but with our default CFLAGS as well). Alas, that's not the case anymore, becase after 14.04's EOL Travis CI's current default Linux image is based on Ubuntu 16.04 Xenial [1] and its default 'cc' is now GCC 5.4, which, just like all later GCC and Clang versions, simply accepts this construct, even if we don't explicitly specify '-std=c99'. Ideally we would adjust our CFLAGS used with DEVELOPER=1 to catch this undesired construct already when contributors build Git on their own machines. Unfortunately, however, there seems to be no compiler option that would catch only this particular construct without choking on many other things, e.g. while a later compiler with '-std=c90' and/or '-ansi' does catch this construct, it can't build Git because of several screenfulls of other errors. Add the 'linux-gcc-4.8' job to Travis CI, in order to build Git with GCC 4.8, and thus to timely catch any 'for' loop initial declarations. To catch those it's sufficient to only build Git with GCC 4.8, so don't run the test suite in this job, because 'make test' takes rather long [2], and it's already run five times in other jobs, so we wouldn't get our time's worth. [1] The Azure Pipelines builds have been using Ubuntu 16.04 images from the start, so I belive they never caught 'for' loop initial declarations. [2] On Travis CI 'make test' alone would take about 9 minutes in this new job (without running httpd, Subversion, and P4 tests). For comparison, starting the job and building Git with GCC 4.8 takes only about 2 minutes. Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

travis-ci: introduce a $jobname variable for 'ci/*' scripts A couple of 'ci/*' scripts are shared between different build jobs: 'ci/lib-travisci.sh', being a common library, is sourced from almost every script, while 'ci/install-dependencies.sh', 'ci/run-build.sh' and 'ci/run-tests.sh' are shared between the "regular" GCC and Clang Linux and OSX build jobs, and the latter two scripts are used in the GETTEXT_POISON Linux build job as well. Our builds could benefit from these shared scripts being able to easily tell which build job they are taking part in. Now, it's already quite easy to tell apart Linux vs OSX and GCC vs Clang build jobs, but it gets trickier with all the additional Linux-based build jobs included explicitly in the build matrix. Unfortunately, Travis CI doesn't provide much help in this regard. The closest we've got is the $TRAVIS_JOB_NUMBER variable, the value of which is two dot-separated integers, where the second integer indicates a particular build job. While it would be possible to use that second number to identify the build job in our shared scripts, it doesn't seem like a good idea to rely on that: - Though the build job numbering sequence seems to be stable so far, Travis CI's documentation doesn't explicitly states that it is indeed stable and will remain so in the future. And even if it were stable, - if we were to remove or insert a build job in the middle, then the job numbers of all subsequent build jobs would change accordingly. So roll our own means of simple build job identification and introduce the $jobname environment variable in our builds, setting it in the environments of the explicitly included jobs in '.travis.yml', while constructing one in 'ci/lib-travisci.sh' as the combination of the OS and compiler name for the GCC and Clang Linux and OSX build jobs. Use $jobname instead of $TRAVIS_OS_NAME in scripts taking different actions based on the OS and build job (when installing P4 and Git LFS dependencies and including them in $PATH). The following two patches will also rely on $jobname. Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

travis-ci: build Git during the 'script' phase Ever since we started building and testing Git on Travis CI (522354d70 (Add Travis CI support, 2015-11-27)), we build Git in the 'before_script' phase and run the test suite in the 'script' phase (except in the later introduced 32 bit Linux and Windows build jobs, where we build in the 'script' phase'). Contrarily, the Travis CI practice is to build and test in the 'script' phase; indeed Travis CI's default build command for the 'script' phase of C/C++ projects is: ./configure && make && make test The reason why Travis CI does it this way and why it's a better approach than ours lies in how unsuccessful build jobs are categorized. After something went wrong in a build job, its state can be: - 'failed', if a command in the 'script' phase returned an error. This is indicated by a red 'X' on the Travis CI web interface. - 'errored', if a command in the 'before_install', 'install', or 'before_script' phase returned an error, or the build job exceeded the time limit. This is shown as a red '!' on the web interface. This makes it easier, both for humans looking at the Travis CI web interface and for automated tools querying the Travis CI API, to decide when an unsuccessful build is our responsibility requiring human attention, i.e. when a build job 'failed' because of a compiler error or a test failure, and when it's caused by something beyond our control and might be fixed by restarting the build job, e.g. when a build job 'errored' because a dependency couldn't be installed due to a temporary network error or because the OSX build job exceeded its time limit. The drawback of building Git in the 'before_script' phase is that one has to check the trace log of all 'errored' build jobs, too, to see what caused the error, as it might have been caused by a compiler error. This requires additional clicks and page loads on the web interface and additional complexity and API requests in automated tools. Therefore, move building Git from the 'before_script' phase to the 'script' phase, updating the script's name accordingly as well. 'ci/run-builds.sh' now becomes basically empty, remove it. Several of our build job configurations override our default 'before_script' to do nothing; with this change our default 'before_script' won't do anything, either, so remove those overriding directives as well.
