Ævar Arnfjörð Bjarmason	6cdccfce1e	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>	6 years ago
SZEDER Gábor	aea8879a6a	travis-ci: include the trash directories of failed tests in the trace log The trash directory of a failed test might contain invaluable information about the cause of the failure, but we have no access to the trash directories of Travis CI build jobs. The only feedback we get from there is the build job's trace log, so... Modify 'ci/print-test-failures.sh' to create a tar.gz archive of the trash directory of each failed test, encode that archive with base64, and print the resulting block of ASCII text, so it gets embedded in the trace log. Furthermore, run tests with '--immediate' to faithfully preserve the failed state. Extracting the trash directories from the trace log turned out to be a bit of a hassle, partly because of the size of these logs (usually resulting in several hundreds or even thousands of lines of base64-encoded text), and partly because these logs have CRLF, CRCRLF and occasionally even CRCRCRLF line endings, which cause 'base64 -d' from coreutils to complain about "invalid input". For convenience add a small script 'ci/util/extract-trash-dirs.sh', which will extract and unpack all base64-encoded trash directories embedded in the log fed to its standard input, and include an example command to be copy-pasted into a terminal to do it all at the end of the failure report. A few of our tests create sizeable trash directories, so limit the size of each included base64-encoded block, let's say, to 1MB. And just in case something fundamental gets broken and a lot of tests fail at once, don't include trash directories when the combined size of the included base64-encoded blocks would exceed 1MB.

SZEDER Gábor	b2cbaa091c	travis-ci: don't repeat the path of the cache directory Some of our 'ci/*' scripts repeat the name or full path of the Travis CI cache directory, and the following patches will add new places using that path. Use a variable to refer to the path of the cache directory instead, so it's hard-coded only in a single place. Pay extra attention to the 32 bit Linux build: it runs in a Docker container, so pass the path of the cache directory from the host to the container in an environment variable. Note that an environment variable passed this way is exported inside the container, therefore its value is directly available in the 'su' snippet even though that snippet is single quoted. Furthermore, use the variable in the container only if it's been assigned a non-empty value, to prevent errors when someone is running or debugging the Docker build locally, because in that case the variable won't be set as there won't be any Travis CI cache.

SZEDER Gábor	b92cb86ea1	travis-ci: check that all build artifacts are .gitignore-d Every once in a while our explicit .gitignore files get out of sync when our build process learns to create new artifacts, like test helper executables, but the .gitignore files are not updated accordingly. Use Travis CI to help catch such issues earlier: check that there are no untracked files at the end of any build jobs building Git (i.e. the 64 bit Clang and GCC Linux and OSX build jobs, plus the GETTEXT_POISON and 32 bit Linux build jobs) or its documentation, and fail the build job if there are any present.

SZEDER Gábor	88e00b7033	travis-ci: don't store P4 and Git LFS in the working tree The Clang and GCC 64 bit Linux build jobs download and store the P4 and Git LFS executables under the current directory, which is the working tree that we are about to build and test. This means that Git commands like 'status' or 'ls-files' would list these files as untracked. The next commit is about to make sure that there are no untracked files present after the build, and the downloaded executables in the working tree are interfering with those upcoming checks. Therefore, let's download P4 and Git LFS in the home directory, outside of the working tree.

SZEDER Gábor	9cc2c76f5e	travis-ci: record and skip successfully built trees Travis CI dutifully builds and tests each new branch tip, even if its tree has previously been successfully built and tested. This happens often enough in contributors' workflows, when a work-in-progress branch is rebased changing e.g. only commit messages or the order or number of commits while leaving the resulting code intact, and is then pushed to a Travis CI-enabled GitHub fork. This is wasting Travis CI's resources and is sometimes scary-annoying when the new tip commit with a tree identical to the previous, successfully tested one is suddenly reported in red, because one of the OSX build jobs happened to exceed the time limit yet again. So extend our Travis CI build scripts to skip building commits whose trees have previously been successfully built and tested. Use the Travis CI cache feature to keep a record of the object names of trees that tested successfully, in a plain and simple flat text file, one line per tree object name. Append the current tree's object name at the end of every successful build job to this file, along with a bit of additional info about the build job (commit object name, Travis CI job number and id). Limit the size of this file to 1000 records, to prevent it from growing too large for git/git's forever living integration branches. Check, using a simple grep invocation, in each build job whether the current commit's tree is already in there, and skip the build if it is. Include a message in the skipped build job's trace log, containing the URL to the build job successfully testing that tree for the first time and instructions on how to force a re-build. Catch the case when a build job, which successfully built and tested a particular tree for the first time, is restarted and omit the URL of the previous build job's trace log, as in this case it's the same build job and the trace log has just been overwritten. Note: this won't kick in if two identical trees are on two different branches, because Travis CI caches are not shared between build jobs of different branches.

SZEDER Gábor	b4a2fdc9bd	travis-ci: create the cache directory early in the build process It seems that Travis CI creates the cache directory for us anyway, even when a previous cache doesn't exist for the current build job. Alas, this behavior is not explicitly documented, therefore we don't rely on it and create the cache directory ourselves in those build jobs that read/write cached data (currently only the prove state). In the following commit we'll start to cache additional data in every build job, and will access the cache much earlier in the build process. Therefore move creating the cache directory to 'ci/lib-travisci.sh' to make sure that it exists at the very beginning of every build job.

SZEDER Gábor	a8b8b6b87d	travis-ci: fine tune the use of 'set -x' in 'ci/' scripts The change in commit `4f2636667` (travis-ci: use 'set -x' in 'ci/' scripts for extra tracing output, 2017-12-12) left a couple of rough edges: - 'ci/run-linux32-build.sh' is executed in a Docker container and therefore doesn't source 'ci/lib-travisci.sh', which would enable tracing executed commands. Enable 'set -x' in this script, too. - 'ci/print-test-failures.sh' iterates over all the files containing the exit codes of all the executed test scripts. Since there are over 800 such files, the loop produces way too much noise with tracing executed commands enabled, so disable 'set -x' for this script. - 'ci/run-windows-build.sh' busily waits in a loop for the result of the Windows build, producing too much noise with tracing executed commands enabled as well. Disable 'set -x' for the duration of that loop. Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	7 years ago
SZEDER Gábor	4f26366679	travis-ci: use 'set -x' in 'ci/' scripts for extra tracing output While the build logic was embedded in our '.travis.yml', Travis CI used to produce a nice trace log including all commands executed in those embedded scriptlets. Since `657343a60` (travis-ci: move Travis CI code into dedicated scripts, 2017-09-10), however, we only see the name of the dedicated scripts, but not what those scripts are actually doing, resulting in a less useful trace log. A patch later in this series will move setting environment variables from '.travis.yml' to the 'ci/' scripts, so not even those will be included in the trace log. Use 'set -x' in 'ci/lib-travisci.sh', which is sourced in most other 'ci/*' scripts, so we get trace log about the commands executed in all of those scripts.

SZEDER Gábor	a1157b76eb	travis-ci: set GIT_TEST_HTTPD in 'ci/lib-travisci.sh' Commit `657343a60` (travis-ci: move Travis CI code into dedicated scripts, 2017-09-10) converted '.travis.yml's default 'before_install' scriptlet to the 'ci/install-dependencies.sh' script, and while doing so moved setting GIT_TEST_HTTPD=YesPlease for the 64-bit GCC and Clang Linux build jobs to that script. This is wrong for two reasons: - The purpose of that script is, as its name suggests, to install dependencies, not to set any environment variables influencing which tests should be run (though, arguably, this was already an issue with the original 'before_install' scriptlet). - Setting the variable has no effect anymore, because that script is run in a separate shell process, and the variable won't be visible in any of the other scripts, notably in 'ci/run-tests.sh' responsible for, well, running the tests. Luckily, this didn't have a negative effect on our Travis CI build jobs, because GIT_TEST_HTTPD is a tri-state variable defaulting to "auto" and a functioning web server was installed in those Linux build jobs, so the httpd tests were run anyway. Apparently the httpd tests run just fine without GIT_TEST_HTTPD being set, therefore we could simply remove this environment variable. However, if a bug were to creep in to change the Travis CI build environment to run the tests as root or to not install Apache, then the httpd tests would be skipped and the build job would still succeed. We would only notice if someone actually were to look through the build job's trace log; but who would look at the trace log of a successful build job?! Since httpd tests are important, we do want to run them and we want to be loudly reminded if they can't be run. Therefore, move setting GIT_TEST_HTTPD=YesPlease for the 64-bit GCC and Clang Linux build jobs to 'ci/lib-travisci.sh' to ensure that the build job fails when the httpd tests can't be run. (We could set it in 'ci/run-tests.sh' just as well, but it's better to keep all environment variables in one place in 'ci/lib-travisci.sh'.)

SZEDER Gábor	e3371e9260	travis-ci: move setting environment variables to 'ci/lib-travisci.sh' Our '.travis.yml's 'env.global' section sets a bunch of environment variables for all build jobs, though none of them actually affects all build jobs. It's convenient for us, and in most cases it works just fine, because irrelevant environment variables are simply ignored. However, $GIT_SKIP_TESTS is an exception: it tells the test harness to skip the two test scripts that are prone to occasional failures on OSX, but as it's set for all build jobs those tests are not run in any of the build jobs that are capable to run them reliably, either. Therefore $GIT_SKIP_TESTS should only be set in the OSX build jobs, but those build jobs are included in the build matrix implicitly (i.e. by combining the matrix keys 'os' and 'compiler'), and there is no way to set an environment variable only for a subset of those implicit build jobs. (Unless we were to add new scriptlets to '.travis.yml', which is exactly the opposite direction that we took with commit `657343a60` (travis-ci: move Travis CI code into dedicated scripts, 2017-09-10)). So move setting $GIT_SKIP_TESTS to 'ci/lib-travisci.sh', where it can trivially be set only for the OSX build jobs. Furthermore, move setting all other environment variables from '.travis.yml' to 'ci/lib-travisci.sh', too, because a couple of environment variables are already set there, and this way all environment variables will be set in the same place. All the logic controlling our builds is already in the 'ci/*' scripts anyway, so there is really no good reason to keep the environment variables separately.

SZEDER Gábor	bf427a9451	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>	7 years ago
SZEDER Gábor	83d1efe5d4	travis-ci: fix running P4 and Git LFS tests in Linux build jobs Linux build jobs on Travis CI skip the P4 and Git LFS tests since commit `657343a60` (travis-ci: move Travis CI code into dedicated scripts, 2017-09-10), claiming there are no P4 or Git LFS installed. The reason is that P4 and Git LFS binaries are not installed to a directory in the default $PATH, but their directories are prepended to $PATH. This worked just fine before said commit, because $PATH was set in a scriptlet embedded in our '.travis.yml', thus its new value was visible during the rest of the build job. However, after these embedded scriptlets were moved into dedicated scripts executed in separate shell processes, any variable set in one of those scripts is only visible in that single script but not in any of the others. In this case, 'ci/install-dependencies.sh' downloads P4 and Git LFS and modifies $PATH, but to no effect, because 'ci/run-tests.sh' only sees Travis CI's default $PATH. Move adjusting $PATH to 'ci/lib-travisci.sh', which is sourced in all other 'ci/' scripts, so all those scripts will see the updated $PATH value.
