[Sparse Index] Delete ignored files outside of cone #396

derrickstolee · 2021-07-05T14:19:23Z

The reason we didn't identify the memory problem in #395 was because our manual testing is too simplistic: We never build within one sparse-checkout definition and then switch to another one. If we did that, then we might have noticed that git sparse-checkout set will leave the ignored files alone within those newly-sparse directories.

This is somewhat unexpected from the user point of view: they say they don't want that directory anymore, but we are keeping all untracked files around! This only applies to ignored files, since we refuse to adjust the sparse-checkout definition over a modified or new (unignored) file.

Leaving these ignored files where they are removes any chance that the sparse index can get its correct performance benefits. For now, this behavior change is limited to the sparse index, so users can disable it by disabling the sparse index.

We will want to consult with upstream about this behavior before moving too far down this path. However, it might be a good idea to try this out on the experimental release.

Bonus: There was a bug in find_cache_entry() that is now fixed.

When a sparse directory leaves the sparse-checkout definition, we leave the ignored files in place. This then requires commands like 'git status' to expand a sparse index to find contained '.gitignore' files within the sparse directory. This test is marked as an expected failure, and the failures happen within the ensure_not_expanded lines. Signed-off-by: Derrick Stolee <[email protected]>

Looks good!

This test was very fragile because it shared an index across sparse and non-sparse behavior. Since that expansion and contraction could cause the index to lose its FS Monitor bitmap and token, behavior is fragile to changes in 'git sparse-checkout set'. Rewrite the test to use two clones of the original repo: full and sparse. This allows us to also keep the test files (actual, expect, trace2.txt) out of the repos we are testing with 'git status'.

When changing the scope of a sparse-checkout using cone mode, we might have some tracked directories go out of scope. The current logic removes the tracked files from within those directories, but leaves the ignored files within those directories. This is a bit unexpected to users who have given input to Git saying they don't need those directories anymore. Since these ignored files are typically build output or helper files from IDEs, the users should not need the files now that the tracked files are removed. If the tracked files reappear, then they will have newer timestamps than the build artifacts, so the artifacts will need to be regenerated anyway. Leaving these ignored files in the sparse directories makes it impossible to gain performance benefits in the sparse index. When we track into these directories, we need to know if the files are ignored or not, which might depend on the _tracked_ .gitignore file(s) within the sparse directory. This depends on the indexed version of the file, so the sparse directory must be expanded. By deleting the sparse directories when changing scope (or running 'git sparse-checkout reapply') we regain these performance benefits as if the repository was in a clean state. If users depend on ignored files within the sparse directories, then they have created a bad shape in their repository. This shape makes it impossible to get performance benefits using the sparse index, so they can workaround it (currently) by disabling the sparse index.

What happened to 70ade78?

The iterated search in find_cache_entry() was recently modified to include a loop that searches backwards for a sparse directory entry that matches the given traverse_info and name_entry. However, the string comparison failed to actually concatenate those two strings, so this failed to find a sparse directory when it was not a top-level directory. This caused some errors in rare cases where a 'git checkout' spanned a diff that modified files within the sparse directory entry, but we could not correctly find the entry.

What happened to 70ade78?

That's a very good question. It turns out I didn't finish a rebase, but even finishing that I didn't get that commit on top.

It's pushed now. Thanks for noticing.

This got some feedback that changed how the tests were working so they are more robust. This led to a new commit (0c1ecfb). ``` cbb0ab3 Merge branch 'sparse-index/merge' into vfs-2.33.0 acb8623 t7524: test no longer fails ``` Finally, the commits are merged into `vfs-2.33.0` and also we include a fix to a `microsoft/git` test that is no longer broken.

``` 6e74958 p2000: add 'git checkout -' test and decrease depth 3e1d03c p2000: compress repo names cd94f82 commit: integrate with sparse-index 65e79b8 sparse-index: recompute cache-tree e9a9981 checkout: stop expanding sparse indexes 4b801c8 t1092: document bad 'git checkout' behavior 71e3015 unpack-trees: resolve sparse-directory/file conflicts 5e96df4 t1092: test merge conflicts outside cone defab1b add: allow operating on a sparse-only index 9fc4313 pathspec: stop calling ensure_full_index 0ec03ab add: ignore outside the sparse-checkout in refresh() adf5b15 add: remove ensure_full_index() with --renormalize ``` These commits are equivalent to those already in `next` via gitgitgadget#999. ``` 80b8d6c Merge branch 'sparse-index/add' into stolee/sparse-index/add ``` This merge resolves conflicts with some work that happened in parallel, but is already in upstream `master`. ``` c407b2c t7519: rewrite sparse index test 9dad0d2 sparse-index: silently return when not using cone-mode patterns 2974920 sparse-index: silently return when cache tree fails e7cdaa0 unpack-trees: fix nested sparse-dir search 347410c sparse-checkout: create helper methods 4537233 attr: be careful about sparse directories 5282a86 sparse-index: add SPARSE_INDEX_MEMORY_ONLY flag 3a2f316 sparse-checkout: clear tracked sparse dirs fb47b56 sparse-checkout: add config to disable deleting dirs ``` These commits are the ones under review as of gitgitgadget#1009. Recent review made this less stable. It's a slightly different and more robust version of #396. > Note: I'm still not done with the feedback for upstream, but the remaining feedback is "can we add tests that cover these tricky technical bits?" and in `microsoft/git` these are already covered by the Scalar functional tests (since that's how they were found). ``` 080b02c diff: ignore sparse paths in diffstat d91a647 merge: make sparse-aware with ORT df49b5f merge-ort: expand only for out-of-cone conflicts cdecb85 t1092: add cherry-pick, rebase tests 0c1ecfb sequencer: ensure full index if not ORT strategy 406dfbe sparse-index: integrate with cherry-pick and rebase ``` These commits integrate with `git merge`, `git cherry-pick`, `git revert`, and `git rebase` as of gitgitgadget#1019. This got some feedback that changed how the tests were working so they are more robust. This led to a new commit (0c1ecfb). ``` cbb0ab3 Merge branch 'sparse-index/merge' into vfs-2.33.0 acb8623 t7524: test no longer fails ``` Finally, the commits are merged into `vfs-2.33.0` and also we include a fix to a `microsoft/git` test that is no longer broken.
