2020-02-04index-pack: downgrade twice-resolved REF_DELTA to die()Libravatar Jeff King1-4/+4
When we're resolving a REF_DELTA, we compare-and-swap its type from REF_DELTA to whatever real type the base object has, as discussed in ab791dd138 (index-pack: fix race condition with duplicate bases, 2014-08-29). If the old type wasn't a REF_DELTA, we consider that a BUG(). But as discussed in that commit, we might see this case whenever we try to resolve an object twice, which may happen because we have multiple copies of the base object. So this isn't a bug at all, but rather a sign that the input pack is broken. And indeed, this case is triggered already in t5309.5 and t5309.6, which create packs with delta cycles and duplicate bases. But we never noticed because those tests are marked expect_failure. Those tests were added by b2ef3d9ebb (test index-pack on packs with recoverable delta cycles, 2013-08-23), which was leaving the door open for cases that we theoretically _could_ handle. And when we see an already-resolved object like this, in theory we could keep going after confirming that the previously resolved child->real_type matches base->obj->real_type. But: - enforcing the "only resolve once" rule here saves us from an infinite loop in other parts of the code. If we keep going, then the delta cycle in t5309.5 causes us to loop infinitely, as find_ref_delta_children() doesn't realize which objects have already been resolved. So there would be more changes needed to make this case work, and in the meantime we'd be worse off. - any pack that triggers this is broken anyway. It either has a duplicate base object, or it has a cycle which causes us to bring in a duplicate via --fix-thin. In either case, we'd end up rejecting the pack in write_idx_file(), which also detects duplicates. So the tests have little value in documenting what we _could_ be doing (and have been neglected for 6+ years). Let's switch them to confirming that we handle this case cleanly (and switch out the BUG() for a more informative die() so that we do so).

2020-02-04notes.c: fix off-by-one error when decreasing notes fanoutLibravatar Johan Herland1-0/+6
As noted in the previous commit, the nature of the fanout heuristic in the notes code causes the exact point at which we increase or decrease the notes fanout to vary with the objects being annotated. Since the object ids generated by the test environment are deterministic (by design), the notes generated and tested by t3305 are always the same, and we therefore happen to see the same fanout behavior from one run to the next. Coincidentally, if we were to change the test environment slightly (say by making a test commit on an unrelated branch before we start the t3305 test proper), we not only see the fanout switch happen at different points, we also manage to trigger a _bug_ in the notes code where the fanout 1 -> 0 switch is not applied uniformly across the notes tree, but instead yields a notes tree like this: ... bdeafb301e44b0e4db0f738a2d2a7beefdb70b70 bff2d39b4f7122bd4c5caee3de353a774d1e632a d3/8ec8f851adf470131178085bfbaab4b12ad2a7 e0b173960431a3e692ae929736df3c9b73a11d5b eb3c3aede523d729990ac25c62a93eb47c21e2e3 ... The bug occurs when we are writing out a notes tree with a newly decreased fanout, and the notes tree contains unexpanded subtrees that should be consolidated into the parent tree as a consequence of the decreased fanout): Subtrees that happen to sit at an _even_ level in the internal notes 16-tree structure (in other words: subtrees whose path - "d3" in the example above - is unique in the first nibble - i.e. there are no other note paths that start with "d") are _not_ unpacked as part of the tree writeout. This error will repeat itself in subsequent note trees until the subtree is forced to be unpacked. In t3305 this only happens when the d38ec8f8 note is itself removed from the tree. The error is not severe (no information is lost, and the notes code is able to read/decode this tree and manipulate it correctly), but this is nonetheless a bug in the current implementation that should be fixed. That said, fixing the off-by-one error is not without complications: We must take into account that the load_subtree() call from for_each_note_helper() (that is now done to correctly unpack the subtree while we're writing out the notes tree) may end up inserting unpacked non-notes into the linked list of non_note entries held by the struct notes_tree. Since we are in the process of writing out the notes tree, this linked list is currently in the process of being traversed by write_each_non_note_until(). The unpacked non-notes are necessarily inserted between the last non-note we wrote out, and the next non-note to be written. Hence, we cannot simply hold the next_non_note to write in struct write_each_note_data (as we would then silently skip these newly inserted notes), but must instead always follow the ->next pointer from the last non-note we wrote.

2020-02-04t3305: check notes fanout more carefully and robustlyLibravatar Johan Herland1-25/+76
In short, before this patch, this test script: - creates many notes - verifies that all notes in the notes tree has a fanout of 1 - removes most notes - verifies that the notes in the notes tree now has a fanout of 0 The fanout verification only happened twice: after creating all the notes, and after removing most of them. This patch strengthens the test by checking the fanout after _each_ added/removed note: We assert that the switch from fanout 0 -> 1 happens exactly once while adding notes (and that the switch pervades the entire notes tree). Likewise, we assert that the switch from fanout 1 -> 0 happens exactly once while removing notes. Additionally, we decrease the number of notes left after removal, from 50 to 15 notes, in order to ensure that fanout 1 -> 0 transition keeps happening regardless of external factors[1]. [1]: Currently (with the SHA1 hash function and the deterministic object ids of the test environment) the fanout heuristic in the notes code happens to switch from 0 -> 1 at 109 notes, and from 1 -> 0 at 59 notes. However, changing the hash function or other external factors will vary these numbers, and the latter may - in theory - go as low as 15.

Apply a similar treatment as in the previous patch to pass a 'struct object_directory *' through the 'load_commit_graph_one_fd_st' initializer, too.

2020-02-04commit-graph.c: remove path normalization, comparisonLibravatar Taylor Blau1-3/+3
As of the previous patch, all calls to 'commit-graph.c' functions which perform path normalization (for e.g., 'get_commit_graph_filename()') are of the form 'ctx->odb->path', which is always in normalized form. Now that there are no callers passing non-normalized paths to these functions, ensure that future callers are bound by the same restrictions by making these functions take a 'struct object_directory *' instead of a 'const char *'. To match, replace all calls with arguments of the form 'ctx->odb->path' with 'ctx->odb' To recover the path, functions that perform path manipulation simply use 'odb->path'. Further, avoid string comparisons with arguments of the form 'odb->path', and instead prefer raw pointer comparisons, which accomplish the same effect, but are far less brittle. This has a pleasant side-effect of making these functions much more robust to paths that cannot be normalized by 'normalize_path_copy()', i.e., because they are outside of the current working directory. For example, prior to this patch, Valgrind reports that the following uninitialized memory read [1]: $ ( cd t && GIT_DIR=../.git valgrind git rev-parse HEAD^ ) because 'normalize_path_copy()' can't normalize '../.git' (since it's relative to but above of the current working directory) [2]. By using a 'struct object_directory *' directly, 'get_commit_graph_filename()' does not need to normalize, because all paths are relative to the current working directory since they are always read from the '->path' of an object directory. [1]: https://lore.kernel.org/git/20191027042116.GA5801@sigill.intra.peff.net. [2]: The bug here is that 'get_commit_graph_filename()' returns the result of 'normalize_path_copy()' without checking the return value.

2020-01-31sparse-checkout: fix cone mode behavior mismatchLibravatar Derrick Stolee1-0/+12
The intention of the special "cone mode" in the sparse-checkout feature is to always match the same patterns that are matched by the same sparse-checkout file as when cone mode is disabled. When a file path is given to "git sparse-checkout set" in cone mode, then the cone mode improperly matches the file as a recursive path. When setting the skip-worktree bits, files were not expecting the MATCHED_RECURSIVE response, and hence these were left out of the matched cone. Fix this bug by checking for MATCHED_RECURSIVE in addition to MATCHED and add a test that prevents regression.

If a user somehow creates a directory with an asterisk (*) or backslash (\), then the "git sparse-checkout set" command will struggle to provide the correct pattern in the sparse-checkout file. When not in cone mode, the provided pattern is written directly into the sparse-checkout file. However, in cone mode we expect a list of paths to directories and then we convert those into patterns. Even more specifically, the goal is to always allow the following from the root of a repo: git ls-tree --name-only -d HEAD | git sparse-checkout set --stdin The ls-tree command provides directory names with an unescaped asterisk. It also quotes the directories that contain an escaped backslash. We must remove these quotes, then keep the escaped backslashes. Use unquote_c_style() when parsing lines from stdin. Command-line arguments will be parsed as-is, assuming the user can do the correct level of escaping from their environment to match the exact directory names.

This matching only works if the patterns in the sparse-checkout file are those written by that command. Users can edit the sparse-checkout file and create patterns that cause the cone mode matching to fail. The cone mode patterns may end in "/*" but otherwise an un-escaped asterisk or other glob character is invalid. Add checks to disable cone mode when seeing these values. A later change will properly handle escaped globs. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-01-31t5318: don't pass non-object directory to '--object-dir'Libravatar Taylor Blau1-2/+2
In f237c8b6fe (commit-graph: implement git-commit-graph write, 2018-04-02) the test t5318.3 was introduced to ensure that calling 'git commit-graph write' in a repository with no packfiles does not write any commit-graph file(s). To exercise more paths in 'builtin/commit-graph.c', this test passes '--object-dir' to 'git commit-graph write', but the given argument refers to the working copy, not the object directory. Since the commit-graph sub-commands currently swallow these errors, this does not result in a test failure. But, it is only lucky that the test ends with no commit-graphs, since there were none to begin with. In preparation for a future commit where an '--object-dir' argument that does not match a known object directory will print out a failure, let's fix the test to still use '--object-dir', but pass the correct location to the object store instead of '.'.

2020-01-31diff: move diff.wsErrorHighlight to "basic" configLibravatar Jeff King1-0/+13
We parse diff.wsErrorHighlight in git_diff_ui_config(), meaning that it doesn't take effect for plumbing commands, only for porcelains like git-diff itself. This is mildly annoying as it means scripts like add--interactive, which produce a user-visible diff with color, don't respect the option. We could teach that script to parse the config and pass it along as --ws-error-highlight to the diff plumbing. But there's a simpler solution. It should be reasonably safe for plumbing to respect this option, as it only kicks in when color is otherwise enabled. And anybody parsing colorized output must already deal with the fact that color.diff.* may change the exact output they see; those options have been part of git_diff_basic_config() since its inception in 9a1805a872 (add a "basic" diff config callback, 2008-01-04). So we can just move it to the "basic" config, which fixes add--interactive, along with any other script in the same boat, with a very low risk of hurting any plumbing users.
