2022-01-14t1011: add testcase demonstrating accidental loss of user modificationsLibravatar Elijah Newren1-0/+21
If a user has a file with local modifications that is not marked as SKIP_WORKTREE, but the sparsity patterns are such that it should be marked that way, and the user then invokes a command like * git checkout -q HEAD^ or * git read-tree -mu HEAD^ Then the file will be deleted along with all the users' modifications. Add a testcase demonstrating this problem. Note: This bug only triggers if something other than 'HEAD' is given; if the commands above had specified 'HEAD', then the users' file would be left alone.

2022-01-13update-index: reduce scope of index expansion in do_reupdateLibravatar Victoria Dye1-1/+4
Replace unconditional index expansion in 'do_reupdate()' with one scoped to only where a full index is needed. A full index is only required in 'do_reupdate()' when a sparse directory in the index differs from HEAD; in that case, the index is expanded and the operation restarted. Because the index should only be expanded if a sparse directory is modified, add a test ensuring the index is not expanded when differences only exist within the sparse cone.

2022-01-13update-index: integrate with sparse indexLibravatar Victoria Dye1-0/+15
Enable use of the sparse index with `update-index`. Most variations of `update-index` work without explicitly expanding the index or making any other updates in or outside of `update-index.c`. The one usage requiring additional changes is `--cacheinfo`; if a file inside a sparse directory was specified, the index would not be expanded until after the cache tree is invalidated, leading to a mismatch between the index and cache tree. This scenario is handled by rearranging `add_index_entry_with_check`, allowing `index_name_stage_pos` to expand the index *before* attempting to invalidate the relevant cache tree path, avoiding cache tree/index corruption.

2022-01-13update-index: add tests for sparse-checkout compatibilityLibravatar Victoria Dye2-0/+168
Introduce tests for a variety of `git update-index` use cases, including performance scenarios. Tests are intended to exercise `update-index` with options that change the commands interaction with the index (e.g., `--again`) and with files/directories inside and outside a sparse checkout cone. Of note is that these tests clearly establish the behavior of `git update-index --add` with untracked, outside-of-cone files. Unlike `git add`, which fails with an error when provided with such files, `update-index` succeeds in adding them to the index. Additionally, the `skip-worktree` flag is *not* automatically added to the new entry. Although this is pre-existing behavior, there are a couple of reasons to avoid changing it in favor of consistency with e.g. `git add`: * `update-index` is low-level command for modifying the index; while it can perform operations similar to those of `add`, it traditionally has fewer "guardrails" preventing a user from doing something they may not want to do (in this case, adding an outside-of-cone, non-`skip-worktree` file to the index) * `update-index` typically only exits with an error code if it is incapable of performing an operation (e.g., if an internal function call fails); adding a new file outside the sparse checkout definition is still a valid operation, albeit an inadvisable one * `update-index` does not implicitly set flags (e.g., `skip-worktree`) when creating new index entries with `--add`; if flags need to be updated, options like `--[no-]skip-worktree` allow a user to intentionally set them All this to say that, while there are valid reasons to consider changing the treatment of outside-of-cone files in `update-index`, there are also sufficient reasons for leaving it as-is.

2022-01-13checkout-index: integrate with sparse indexLibravatar Victoria Dye1-1/+10
Add repository settings to allow usage of the sparse index. When using the `--all` option, sparse directories are ignored by default due to the `skip-worktree` flag, so there is no need to expand the index. If `--ignore-skip-worktree-bits` is specified, the index is expanded in order to check out all files. When checking out individual files, existing behavior in a full index is to exit with an error if a directory is specified (as the directory name will not match an index entry). However, it is possible in a sparse index to match a directory name to a sparse directory index entry, but checking out that sparse directory still results in an error on checkout. To reduce some potential confusion for users, `checkout_file(...)` explicitly exits with an informative error if provided with a sparse directory name. The test corresponding to this scenario verifies the error message, which now differs between sparse index and non-sparse index checkouts.

2022-01-13checkout-index: add --ignore-skip-worktree-bits optionLibravatar Victoria Dye1-10/+17
Update `checkout-index` to no longer refresh files that have the `skip-worktree` bit set, exiting with an error if `skip-worktree` filenames are directly provided to `checkout-index`. The newly-added `--ignore-skip-worktree-bits` option provides a mechanism to replicate the old behavior, checking out *all* files specified (even those with `skip-worktree` enabled). The ability to toggle whether files should be checked-out based on `skip-worktree` already exists in `git checkout` and `git restore` (both of which have an `--ignore-skip-worktree-bits` option). The change to, by default, ignore `skip-worktree` files is especially helpful for sparse-checkout; it prevents inadvertent creation of files outside the sparse definition on disk and eliminates the need to expand a sparse index when using the `--all` option. Internal usage of `checkout-index` in `git stash` and `git filter-branch` do not make explicit use of files with `skip-worktree` enabled, so `--ignore-skip-worktree-bits` is not added to them.

Add tests to cover `checkout-index`, with a focus on cases interesting in a sparse checkout (e.g., files specified outside sparse checkout definition). New tests are intended to serve as a baseline for existing and/or expected behavior and performance when integrating `checkout-index` with the sparse index.

Update t1092 test 'reset with pathspecs outside sparse definition' to verify index contents. The use of `rev-parse` verifies the contents of HEAD, not the index, providing no real validation of the reset results. Conversely, `ls-files` reports the contents of the index (OIDs, flags, filenames), which are then compared across checkouts to ensure compatible index states.

2022-01-10fmt-merge-msg: prevent use-after-free with signed tagsLibravatar Taylor Blau1-0/+8
When merging a signed tag, fmt_merge_msg_sigs() is responsible for populating the body of the merge message with the names of the signed tags, their signatures, and the validity of those signatures. In 02769437e1 (ssh signing: use sigc struct to pass payload, 2021-12-09), check_signature() was taught to pass the object payload via the sigc struct instead of passing the payload buffer separately. In effect, 02769437e1 causes buf, and sigc.payload to point at the same region in memory. This causes a problem for fmt_tag_signature(), which wants to read from this location, since it is freed beforehand by signature_check_clear() (which frees it via sigc's `payload` member). That makes the subsequent use in fmt_tag_signature() a use-after-free. As a result, merge messages did not contain the body of any signed tags. Luckily, they tend not to contain garbage, either, since the result of strstr()-ing the object buffer in fmt_tag_signature() is guarded: const char *tag_body = strstr(buf, "\n\n"); if (tag_body) { tag_body += 2; strbuf_add(tagbuf, tag_body, buf + len - tag_body); } Unfortunately, the tests in t6200 did not catch this at the time because they do not search for the body of signed tags in fmt-merge-msg's output. Resolve this by waiting to call signature_check_clear() until after its contents can be safely discarded. Harden ourselves against any future regressions in this area by making sure we can find signed tag messages in the output of fmt-merge-msg, too.

In commit bee8691f19 ("stash: restore untracked files AFTER restoring tracked files", 2021-09-10), we correctly identified that we should restore changes to tracked files before attempting to restore untracked files, and accordingly moved the code for restoring untracked files a few lines down in do_apply_stash(). Unfortunately, the intervening lines had some early return statements meaning that we suddenly stopped restoring untracked files in some cases. Even before the previous commit, there was another possible issue with the current code -- a post-stash-apply 'git status' that was intended to be run after restoring the stash was skipped when we hit a conflict (or other error condition), which seems slightly inconsistent.

2021-12-30sparse-checkout: refuse to add to bad patternsLibravatar Derrick Stolee1-2/+5
When in cone mode sparse-checkout, it is unclear how 'git sparse-checkout add <dir1> ...' should behave if the existing sparse-checkout file does not match the cone mode patterns. Change the behavior to fail with an error message about the existing patterns. Also, all cone mode patterns start with a '/' character, so add that restriction. This is necessary for our example test 'cone mode: warn on bad pattern', but also requires modifying the example sparse-checkout file we use to test the warnings related to recognizing cone mode patterns. This error checking would cause a failure further down the test script because of a test that adds non-cone mode patterns without cleaning them up. Perform that cleanup as part of the test now.

2021-12-30sparse-checkout: fix OOM error with mixed patternsLibravatar Derrick Stolee1-0/+11
Add a test to t1091-sparse-checkout-builtin.sh that would result in an infinite loop and out-of-memory error before this change. The issue relies on having non-cone-mode patterns while trying to modify the patterns in cone-mode. The fix is simple, allowing us to break from the loop when the input path does not contain a slash, as the "dir" pattern we added does not. This is only a fix to the critical out-of-memory error. A better response to such a strange state will follow in a later change.
