2020-01-30grep: ignore --recurse-submodules if --no-index is givenLibravatar Philippe Blain1-1/+10
Since grep learned to recurse into submodules in 0281e487fd (grep: optionally recurse into submodules, 2016-12-16), using --recurse-submodules along with --no-index makes Git die(). This is unfortunate because if submodule.recurse is set in a user's ~/.gitconfig, invoking `git grep --no-index` either inside or outside a Git repository results in fatal: option not supported with --recurse-submodules Let's allow using these options together, so that setting submodule.recurse globally does not prevent using `git grep --no-index`. Using `--recurse-submodules` should not have any effect if `--no-index` is used inside a repository, as Git will recurse into the checked out submodule directories just like into regular directories.

2020-01-28git rm submodule: succeed if .gitmodules index stat info is zeroLibravatar David Turner1-0/+7
The bug was that ie_match_stat() was used to compare if the stat info for the file was compatible with the stat info in the index, rather using ie_modified() to check if the file was in fact different from the version in the index. A version of this (with deinit instead of rm) was reported here: https://lore.kernel.org/git/CAPOqYV+C-P9M2zcUBBkD2LALPm4K3sxSut+BjAkZ9T1AKLEr+A@mail.gmail.com/ It seems that in that case, the user's clone command left the index with empty stat info. The mailing list was unable to reproduce this. But we (Two Sigma) hit the bug while using some plumbing commands, so I'm fixing it. I manually confirmed that the fix also repairs deinit in this scenario.

2020-01-27t5616: make robust to delta base changeLibravatar Jonathan Tan1-13/+23
Commit 6462d5eb9a ("fetch: remove fetch_if_missing=0", 2019-11-08) contains a test that relies on having to lazily fetch the delta base of a blob, but assumes that the tree being fetched (as part of the test) is sent as a non-delta object. This assumption may not hold in the future; for example, a change in the length of the object hash might result in the tree being sent as a delta instead. Make the test more robust by relying on having to lazily fetch the delta base of the tree instead, and by making no assumptions on whether the blobs are sent as delta or non-delta.

2020-01-27verify_filename(): handle backslashes in "wildcards are pathspecs" ruleLibravatar Jeff King1-0/+14
Commit 28fcc0b71a (pathspec: avoid the need of "--" when wildcard is used, 2015-05-02) allowed: git rev-parse '*.c' without the double-dash. But the rule it uses to check for wildcards actually looks for any glob special. This is overly liberal, as it means that a pattern that doesn't actually do any wildcard matching, like "a\b", will be considered a pathspec. If you do have such a file on disk, that's presumably what you wanted. But if you don't, the results are confusing: rather than say "there's no such path a\b", we'll quietly accept it as a pathspec which very likely matches nothing (or at least not what you intended). Likewise, looking for path "a\*b" doesn't expand the search at all; it would only find a single entry, "a*b". This commit switches the rule to trigger only when glob metacharacters would expand the search, meaning both of those cases will now report an error (you can still disambiguate using "--", of course; we're just tightening the DWIM heuristic). Note that we didn't test the original feature in 28fcc0b71a at all. So this patch not only tests for these corner cases, but also adds a regression test for the existing behavior.

2020-01-22submodule.c: use get_git_dir() instead of get_git_common_dir()Libravatar Philippe Blain1-0/+33
Ever since df56607dff (git-common-dir: make "modules/" per-working-directory directory, 2014-11-30), submodules in linked worktrees are cloned to $GIT_DIR/modules, i.e. $GIT_COMMON_DIR/worktrees/<name>/modules. However, this convention was not followed when the worktree updater commands checkout, reset and read-tree learned to recurse into submodules. Specifically, submodule.c::submodule_move_head, introduced in 6e3c1595c6 (update submodules: add submodule_move_head, 2017-03-14) and submodule.c::submodule_unset_core_worktree, (re)introduced in 898c2e65b7 (submodule: unset core.worktree if no working tree is present, 2018-12-14) use get_git_common_dir() instead of get_git_dir() to get the path of the submodule repository. This means that, for example, 'git checkout --recurse-submodules <branch>' in a linked worktree will correctly checkout <branch>, detach the submodule's HEAD at the commit recorded in <branch> and update the submodule working tree, but the submodule HEAD that will be moved is the one in $GIT_COMMON_DIR/modules/<name>/, i.e. the submodule repository of the main superproject working tree. It will also rewrite the gitfile in the submodule working tree of the linked worktree to point to $GIT_COMMON_DIR/modules/<name>/. This leads to an incorrect (and confusing!) state in the submodule working tree of the main superproject worktree. Additionally, if switching to a commit where the submodule is not present, submodule_unset_core_worktree will be called and will incorrectly remove 'core.wortree' from the config file of the submodule in the main superproject worktree, $GIT_COMMON_DIR/modules/<name>/config. Fix this by constructing the path to the submodule repository using get_git_dir() in both submodule_move_head and submodule_unset_core_worktree.

2020-01-22t2405: clarify test descriptions and simplify testLibravatar Philippe Blain1-20/+16
When 'checkout --to' functionality was moved to 'worktree add', tests were adapted in f194b1ef6e (tests: worktree: retrofit "checkout --to" tests for "worktree add", 2015-07-06). The calls were changed to 'worktree add' in this test (then t7410), but the test descriptions were not updated, keeping 'checkout' instead of using the new terminology (linked worktrees). Also, in the test each worktree is created in $TRASH_DIRECTORY/<leading-directory>/main, where the name of <leading-directory> carries some information about what behavior each test verifies. This directory structure is not mandatory for the tests; the worktrees can live next to one another in the trash directory. Clarify the tests by using the right terminology, and remove the unnecessary leading directories such that all superproject worktrees are directly next to one another in the trash directory.

2020-01-21fetch: document and test --refmap=""Libravatar Derrick Stolee1-0/+24
To prevent long blocking time during a 'git fetch' call, a user may want to set up a schedule for background 'git fetch' processes. However, these runs will update the refs/remotes branches due to the default refspec set in the config when Git adds a remote. Hence the user will not notice when remote refs are updated during their foreground fetches. In fact, they may _want_ those refs to stay put so they can work with the refs from their last foreground fetch call. This can be accomplished by overriding the configured refspec using '--refmap=' along with a custom refspec: git fetch --refmap='' <remote> +refs/heads/*:refs/hidden/<remote>/* to populate a custom ref space and download a pack of the new reachable objects. This kind of call allows a few things to happen: 1. We download a new pack if refs have updated. 2. Since the refs/hidden branches exist, GC will not remove the newly-downloaded data. 3. With fetch.writeCommitGraph enabled, the refs/hidden refs are used to update the commit-graph file. To avoid the refs/hidden directory from filling without bound, the --prune option can be included. When providing a refspec like this, the --prune option does not delete remote refs and instead only deletes refs in the target refspace. Update the documentation to clarify how '--refmap=""' works and create tests to guarantee this behavior remains in the future.

2020-01-16t7800: don't rely on reuse_worktree_file()Libravatar Jeff King1-3/+2
A test in t7800 tries to make sure that when git-difftool runs an external tool that fails, it stops looking at files. Our fake failing tool prints the file name it was asked to diff before exiting non-zero, and then we confirm the output contains only that file. However, this subtly relies on our internal reuse_worktree_file(). Because we're diffing between branches, the command run by difftool might see: - the git-stored filename (e.g., "file"), if we decided that the working tree contents were up-to-date with the object in the index and HEAD, and we could reuse them - a temporary filename (e.g. "/tmp/abc123_file") if we had to dump the contents from the object database If the latter case happens, then the test fails, because it's expecting the string "file". I discovered this when debugging something unrelated with reuse_worktree_file(). I _thought_ it should be able to be triggered by a racy-git situation, but running: ./t7800-difftool.sh --stress --run=2,13 never seems to fail. However, by my reading of reuse_worktree_file(), this would probably always fail under Cygwin, because it sets NO_FAST_WORKING_DIRECTORY. At any rate, since reuse_worktree_file() is meant to be an optimization that may or may not trigger, our test should be robust either way. Instead of checking the filename, let's just make sure we got a single line of output (which would not be true if we continued after the first failure).

2020-01-16t4018: drop "debugging" cat from hunk-header testsLibravatar Jeff King1-1/+0
We run a series of hunk-header tests in a loop, and each one does this: test_when_finished 'cat actual' && # for debugging only This is pretty pointless. When the test succeeds, we waste time running a useless cat process. If you're debugging a failure with "-i", then we won't run the when-finished part at all. So it helps only if you're running with something like "--verbose-log". Since we expect the tests to succeed most of the time, a better way to do this would be a helper that checks the output and dumps "actual" only when it fails. But it's probably not even worth the effort, as anyone debugging a failure could just run with "-i" and investigate the "actual" file themselves.

2020-01-16dir: treat_leading_path() and read_directory_recursive(), round 2Libravatar Elijah Newren1-1/+1
I was going to title this "dir: more synchronizing of treat_leading_path() and read_directory_recursive()", a nod to commit 777b42034764 ("dir: synchronize treat_leading_path() and read_directory_recursive()", 2019-12-19), but the title was too long. Anyway, first the backstory... fill_directory() has always had a slightly error-prone interface: it returns a subset of paths which *might* match the specified pathspec; it was intended to prune away some paths which didn't match the specified pathspec and keep at least all the ones that did match it. Given this interface, callers were responsible to post-process the results and check whether each actually matched the pathspec. builtin/clean.c did this. It would first prune out duplicates (e.g. if "dir" was returned as well as all files under "dir/", then it would simplify this to just "dir"), and after pruning duplicates it would compare the remaining paths to the specified pathspec(s). This post-processing itself could run into problems, though, as noted in commit 404ebceda01c ("dir: also check directories for matching pathspecs", 2019-09-17): For the case of git-clean and a set of pathspecs of "dir/file" and "more", this caused a problem because we'd end up with dir entries for both of "dir" "dir/file" Then correct_untracked_entries() would try to helpfully prune duplicates for us by removing "dir/file" since it's under "dir", leaving us with "dir" Since the original pathspec only had "dir/file", the only entry left doesn't match and leaves nothing to be removed. (Note that if only one pathspec was specified, e.g. only "dir/file", then the common_prefix_len optimizations in fill_directory would cause us to bypass this problem, making it appear in simple tests that we could correctly remove manually specified pathspecs.) That commit fixed the issue -- when multiple pathspecs were specified -- by making sure fill_directory() wouldn't return both "dir" and "dir/file" outside the common_prefix_len optimization path. This is where it starts to get fun. In commit b9670c1f5e6b ("dir: fix checks on common prefix directory", 2019-12-19), we noticed that the common_prefix_len wasn't doing appropriate checks and letting all kinds of stuff through, resulting in recursing into .git/ directories and other craziness. So it started locking down and doing checks on pathnames within that code path. That continued with commit 777b42034764 ("dir: synchronize treat_leading_path() and read_directory_recursive()", 2019-12-19), which noted the following: Our optimization to avoid calling into read_directory_recursive() when all pathspecs have a common leading directory mean that we need to match the logic that read_directory_recursive() would use if we had just called it from the root. Since it does more than call treat_path() we need to copy that same logic. ...and then it more forcefully addressed the issue with this wonderfully ironic statement: Needing to duplicate logic like this means it is guaranteed someone will eventually need to make further changes and forget to update both locations. It is tempting to just nuke the leading_directory special casing to avoid such bugs and simplify the code, but unpack_trees' verify_clean_subdirectory() also calls read_directory() and does so with a non-empty leading path, so I'm hesitant to try to restructure further. Add obnoxious warnings to treat_leading_path() and read_directory_recursive() to try to warn people of such problems. You would think that with such a strongly worded description, that its author would have actually ensured that the logic in treat_leading_path() and read_directory_recursive() did actually match and that *everything* that was needed had at least been copied over at the time that this paragraph was written. But you'd be wrong, I messed it up by missing part of the logic. Copy the missing bits to fix the new final test in t7300.

2020-01-16clean: demonstrate a bug with pathspecsLibravatar Derrick Stolee1-0/+9
b9670c1f5e (dir: fix checks on common prefix directory, 2019-12-19) modified the way pathspecs are handled when handling a directory during "git clean -f <path>". While this improved the behavior for known test breakages, it also regressed in how the clean command handles cleaning a specified file. Add a test case that demonstrates this behavior. This test passes before b9670c1f5e then fails after.

2020-01-15t5604: make hash independentLibravatar brian m. carlson1-2/+3
To make our values hash independent, we turn the directory of the object into "Y" and the file name into "Z" after having sorted items by their name. However, when using SHA-256, one of our file names begins with an "a" character, which means it sorts into the wrong place in the list, causing the test to fail. Since we don't care about the order of these items, just sort them after stripping actual hash contents, which means they'll work with any hash algorithm.

2020-01-15t5601: switch into repository to hash objectLibravatar brian m. carlson1-2/+2
This test performs a clone from outside any repository. Consequently, the hash algorithm used defaults to SHA-1. When the test is running with SHA-256, this results in an object ID that is not usable by the rest of the test. In order to ensure that we provide a usable value, switch into the source repository before hashing.

2020-01-15t5562: use $ZERO_OIDLibravatar brian m. carlson1-1/+1
This test uses $_z40 to express an all-zeros object ID, which doesn't work for SHA-256. Use $ZERO_OID instead, which is the right size for all hash values. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-01-15t5537: make hash size independentLibravatar brian m. carlson1-2/+6
This test modifies a pkt-line stream with sed to change a line with "shallow" to "unshallow". However, this modification is dependent on the size of the hash in use; with SHA-256, the pkt-line length is different, leading to the sed command having no effect. Use test_oid_cache to specify the correct values for each hash so that the test continues to work.
