Johannes Schindelin	c2160f2d19	ci: rename the library of common functions The name is hard-coded to reflect that we use Travis CI for continuous testing. In the next commits, we will extend this to be able use Azure DevOps, too. So let's adjust the name to make it more generic.

SZEDER Gábor	533033024a	travis-ci: don't run the test suite as root in the 32 bit Linux build Travis CI runs the 32 bit Linux build job in a Docker container, where all commands are executed as root by default. Therefore, ever since we added this build job in `88dedd5e7` (Travis: also test on 32-bit Linux, 2017-03-05), we have a bit of code to create a user in the container matching the ID of the host user and then to run the test suite as this user. Matching the host user ID is important, because otherwise the host user would have no access to any files written by processes running in the container, notably the logs of failed tests couldn't be included in the build job's trace log. Alas, this piece of code never worked, because it sets the variable holding the user name ($CI_USER) in a subshell, meaning it doesn't have any effect by the time we get to the point to actually use the variable to switch users with 'su'. So all this time we were running the test suite as root. Reorganize that piece of code in 'ci/run-linux32-build.sh' a bit to avoid that problematic subshell and to ensure that we switch to the right user. Furthermore, make the script's optional host user ID option mandatory, so running the build accidentally as root will become harder when debugging locally. If someone really wants to run the test suite as root, whatever the reasons might be, it'll still be possible to do so by explicitly passing '0' as host user ID. Finally, one last catch: since commit `7e72cfcee` (travis-ci: save prove state for the 32 bit Linux build, 2017-12-27) the 'prove' test harness has been writing its state to the Travis CI cache directory from within the Docker container while running as root. After this patch 'prove' will run as a regular user, so in future build jobs it won't be able overwrite a previously written, still root-owned state file, resulting in build job failures. To resolve this we should manually delete caches containing such root-owned files, but that would be a hassle. Instead, work this around by changing the owner of the whole contents of the cache directory to the host user ID.

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	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	7e72cfceed	travis-ci: save prove state for the 32 bit Linux build This change follows suit of `6272ed319` (travis-ci: run previously failed tests first, then slowest to fastest, 2016-01-26), which did this for the Linux and OSX build jobs. Travis CI build jobs run the tests parallel, which is sligtly faster when tests are run in slowest to fastest order, shortening the overall runtime of this build job by about a minute / 10%. Note, that the 32 bit Linux build job runs the tests suite in a Docker container and we have to share the Travis CI cache directory with the container as a second volume. Otherwise we couldn't use a symlink pointing to the prove state file in the cache directory, because that's outside of the directory hierarchy accessible from within the container.

Lars Schneider	657343a602	travis-ci: move Travis CI code into dedicated scripts Most of the Travis CI commands are in the '.travis.yml'. The yml format does not support functions and therefore code duplication is necessary to run commands across all builds. To fix this, add a library for common CI functions. Move all Travis CI code into dedicated scripts and make them call the library first.
