2019-09-20t/helper: ignore only executable filesLibravatar SZEDER Gábor1-5/+4
This patch conceptually reverts 44103f4197 (t/helper: ignore everything but sources, 2017-12-12). Back in those days we did have a lot of separate test helper executables under 't/helper', and its '.gitignore' did get out of sync every once in a while. Since then, however, most of those separate executables were integrated into a single 'test-tool' command [1], and new test helpers are added as new subcommands, so the chances of that '.gitignore' getting out of sync again are much lower. And even if a contributor were not careful enough and submits a patch that adds a new executable under 't/helper' but forgets to update '.gitignore' accordingly, our CI builds would catch it in a timely manner [2]. Ignoring everything but sources has the drawback that building an older version of Git (e.g. during bisecting) creates all those executables, and after going back to e.g. current 'master' the usual cleanup commands like 'make clean' or 'git clean -fd' don't remove them (the former doesn't know about them, and the latter doesn't remove ignored files). So let's ignore only the executable files under 't/helper/, i.e. 'test-tool' and the three other remaining executables that could not be integrated into 'test-tool' (no need to ignore object files, as they are already ignored by our toplevel '.gitignore'). [1] The topic starting with efd71f8913 (t/helper: add an empty test-tool program, 2018-03-24), and leading up to the merge commit 27f25845cf (Merge branch 'nd/combined-test-helper', 2018-04-11).

2017-12-12t/helper: ignore everything but sourcesLibravatar Stefan Beller1-38/+4
Compiled test helpers in t/helper are out of sync with the .gitignore files quite frequently. This can happen when new test helpers are added, but the explicit .gitignore file is not updated in the same commit, or when you forget to 'make clean' before checking out a different version of git, as the different version may have a different explicit list of test helpers to ignore. Fix this by having an overly broad ignore pattern in that directory: Anything, except C and shell source, will be ignored.

2017-10-01fsmonitor: add a performance testLibravatar Ben Peart1-0/+1
Add a test utility (test-drop-caches) that flushes all changes to disk then drops file system cache on Windows, Linux, and OSX. Add a perf test (p7519-fsmonitor.sh) for fsmonitor. By default, the performance test will utilize the Watchman file system monitor if it is installed. If Watchman is not installed, it will use a dummy integration script that does not report any new or modified files. The dummy script has very little overhead which provides optimistic results. The performance test will also use the untracked cache feature if it is available as fsmonitor uses it to speed up scanning for untracked files. There are 4 environment variables that can be used to alter the default behavior of the performance test: GIT_PERF_7519_UNTRACKED_CACHE: used to configure core.untrackedCache GIT_PERF_7519_SPLIT_INDEX: used to configure core.splitIndex GIT_PERF_7519_FSMONITOR: used to configure core.fsmonitor GIT_PERF_7519_DROP_CACHE: if set, the OS caches are dropped between tests The big win for using fsmonitor is the elimination of the need to scan the working directory looking for changed and untracked files. If the file information is all cached in RAM, the benefits are reduced.
