Here is V4 of Part 3 of my builtin FSMonitor series. This version has been updated to depend upon V8 of Part 2. * [] Feedback on V7 of Part 2 caused a minor change in a unit test in Part 3, so I'm resending Part 3 so that we can test the complete feature. * [] I also changed in Part 2 how some of the untracked cache tests were handled when FSMonitor is disabled, so I've made the corresponding changes here. Here is the range-diff from V3 to V4: 1: 779a15b38e = 1: 23bfb8c516 fsm-listen-win32: handle shortnames 2: 11d4a17b69 = 2: d14f171460 t7527: test FSMonitor on repos with Unicode root paths 3: 901fa32f6e = 3: 4db2370d04 t/helper/fsmonitor-client: create stress test 4: a8f0b2a525 = 4: f2c0569c90 fsmonitor-settings: bare repos are incompatible with FSMonitor 5: e32a8a7ea7 = 5: b2599bb9d2 fsmonitor-settings: stub in Win32-specific incompatibility checking 6: 5546339d96 = 6: 9ad6d87ccc fsmonitor-settings: VFS for Git virtual repos are incompatible 7: 1d2877efda = 7: 7652c79ab3 fsmonitor-settings: stub in macOS-specific incompatibility checking 8: 06d7f18676 = 8: 2f2a523552 fsmonitor-settings: remote repos on macOS are incompatible 9: 5ca97f482d = 9: 0297d80388 fsmonitor-settings: remote repos on Windows are incompatible 10: 6715143724 = 10: b6dfd609ad fsmonitor-settings: NTFS and FAT32 on MacOS are incompatible 11: ed1f723130 = 11: db5197b44b unpack-trees: initialize fsmonitor_has_run_once in o->result 12: 35c77b854b = 12: 3f154d0251 fsm-listen-darwin: ignore FSEvents caused by xattr changes on macOS 13: a5affb359c = 13: 4aade7b560 fsmonitor--daemon: cd out of worktree root 14: 087af5dfb6 = 14: d8ebac2a9b fsmonitor--daemon: prepare for adding health thread 15: e78eb20c1b = 15: 7fb0795e25 fsmonitor--daemon: rename listener thread related variables 16: 301fff5296 = 16: e90adcd06d fsmonitor--daemon: stub in health thread 17: c6b5bdd25e = 17: d9b91a998c fsm-health-win32: add polling framework to monitor daemon health 18: 13d11713a8 = 18: 0e95ee0d01 fsm-health-win32: force shutdown daemon if worktree root moves 19: 01c1a38c46 = 19: 48a590d202 fsm-listen-darwin: shutdown daemon if worktree root is moved/renamed 20: 0f0a5b5ca1 = 20: 36ab239fd9 fsmonitor: optimize processing of directory events 21: d8218d197a ! 21: 3010b22e69 t7527: FSMonitor tests for directory moves @@ Commit message Create unit tests to move a directory.
