2018-10-19Merge branch 'bp/rename-test-env-var'Libravatar Junio C Hamano1-9/+2
Some environment variables that control the runtime options of Git used during tests are getting renamed for consistency. * bp/rename-test-env-var: t0000: do not get self-test disrupted by environment warnings preload-index: update GIT_FORCE_PRELOAD_TEST support read-cache: update TEST_GIT_INDEX_VERSION support fsmonitor: update GIT_TEST_FSMONITOR support preload-index: use git_env_bool() not getenv() for customization t/README: correct spelling of "uncommon"
2018-09-28preload-index: update GIT_FORCE_PRELOAD_TEST supportLibravatar Ben Peart1-2/+2
Rename GIT_FORCE_PRELOAD_TEST to GIT_TEST_PRELOAD_INDEX for consistency with the other GIT_TEST_ special setups and properly document its use. Add logic in t/test-lib.sh to give a warning when the old variable is set to let people know they need to update their environment to use the new variable.

2018-09-28fsmonitor: update GIT_TEST_FSMONITOR supportLibravatar Ben Peart1-7/+0
Rename GIT_FSMONITOR_TEST to GIT_TEST_FSMONITOR for consistency with the other GIT_TEST_ special setups and properly document its use. Add logic in t/test-lib.sh to give a warning when the old variable is set to let people know they need to update their environment to use the new variable. Remove the outdated instructions on how to run the test suite utilizing fsmonitor now that it is properly documented in t/README.

2018-02-07dir.c: ignore paths containing .git when invalidating untracked cacheLibravatar Nguyễn Thái Ngọc Duy1-0/+39
read_directory() code ignores all paths named ".git" even if it's not a valid git repository. See treat_path() for details. Since ".git" is basically invisible to read_directory(), when we are asked to invalidate a path that contains ".git", we can safely ignore it because the slow path would not consider it anyway. This helps when fsmonitor is used and we have a real ".git" repo at worktree top. Occasionally .git/index will be updated and if the fsmonitor hook does not filter it, untracked cache is asked to invalidate the path ".git/index". Without this patch, we invalidate the root directory unncessarily, which: - makes read_directory() fall back to slow path for root directory (slower) - makes the index dirty (because UNTR extension is updated). Depending on the index size, writing it down could also be slow. A note about the new "safe_path" knob. Since this new check could be relatively expensive, avoid it when we know it's not needed. If the path comes from the index, it can't contain ".git". If it does contain, we may be screwed up at many more levels, not just this one.

2017-11-10fsmonitor: store fsmonitor bitmap before splitting indexLibravatar Alex Vandiver1-0/+13
ba1b9cac ("fsmonitor: delay updating state until after split index is merged", 2017-10-27) resolved the problem of the fsmonitor data being applied to the non-base index when reading; however, a similar problem exists when writing the index. Specifically, writing of the fsmonitor extension happens only after the work to split the index has been applied -- as such, the information in the index is only for the non-"base" index, and thus the extension information contains only partial data. When saving, compute the ewah bitmap before the index is split, and store it in the fsmonitor_dirty field, mirroring the behavior that occurred during reading. fsmonitor_dirty is kept from being leaked by being freed when the extension data is written -- which always happens precisely once, no matter the split index configuration.

2017-10-01fsmonitor: add test cases for fsmonitor extensionLibravatar Ben Peart1-0/+304
Test the ability to add/remove the fsmonitor index extension via update-index. Test that dirty files returned from the integration script are properly represented in the index extension and verify that ls-files correctly reports their state. Test that ensure status results are correct when using the new fsmonitor extension. Test untracked, modified, and new files by ensuring the results are identical to when not using the extension. Test that if the fsmonitor extension doesn't tell git about a change, it doesn't discover it on its own. This ensures git is honoring the extension and that we get the performance benefits desired. Three test integration scripts are provided: fsmonitor-all - marks all files as dirty fsmonitor-none - marks no files as dirty fsmonitor-watchman - integrates with Watchman with debug logging To run tests in the test suite while utilizing fsmonitor: First copy t/t7519/fsmonitor-all to a location in your path and then set GIT_FORCE_PRELOAD_TEST=true and GIT_FSMONITOR_TEST=fsmonitor-all and run your tests. Note: currently when using the test script fsmonitor-watchman on Windows, many tests fail due to a reported but not yet fixed bug in Watchman where it holds on to handles for directories and files which prevents the test directory from being cleaned up properly.
