2021-05-27t2080: fix cp invocation to copy symlinks instead of following themLibravatar Matheus Tavares1-1/+1
t2080 makes a few copies of a test repository and later performs a branch switch on each one of the copies to verify that parallel checkout and sequential checkout produce the same results. However, the repository is copied with `cp -R` which, on some systems, defaults to following symlinks on the directory hierarchy and copying their target files instead of copying the symlinks themselves. AIX is one example of system where this happens. Because the symlinks are not preserved, the copied repositories have paths that do not match what is in the index, causing git to abort the checkout operation that we want to test. This makes the test fail on these systems. Fix this by copying the repository with the POSIX flag '-P', which forces cp to copy the symlinks instead of following them. Note that we already use this flag for other cp invocations in our test suite (see t7001). With this change, t2080 now passes on AIX.

2021-05-05parallel-checkout: add tests for basic operationsLibravatar Matheus Tavares2-0/+271
Add tests to populate the working tree during clone and checkout using sequential and parallel mode, to confirm that they produce identical results. Also test basic checkout mechanics, such as checking for symlinks in the leading directories and the abidance to --force. Note: some helper functions are added to a common lib file which is only included by t2080 for now. But they will also be used by other parallel-checkout tests in the following patches.

It's been more than long enough for those users to get a headsup about this. So remove all the scaffolding that was left inplace after d03ebd411c6. I'm also removing the documentation entry, if anyone still has this left in their configuration they can do some source archaeology to figure out what it used to do, which makes more sense than exposing every git user reading the documentation to this legacy configuration switch.

2021-03-23format-patch: allow a non-integral version numbersLibravatar ZheNing Hu2-0/+58
The `-v<n>` option of `format-patch` can give nothing but an integral iteration number to patches in a series.  Some people, however, prefer to mark a new iteration with only a small fixup with a non integral iteration number (e.g. an "oops, that was wrong" fix-up patch for v4 iteration may be labeled as "v4.1"). Allow `format-patch` to take such a non-integral iteration number. `<n>` can be any string, such as '3.1' or '4rev2'. In the case where it is a non-integral value, the "Range-diff" and "Interdiff" headers will not include the previous version.

2021-03-22diff --no-index tests: test mode normalizationLibravatar Ævar Arnfjörð Bjarmason1-0/+55
When "git diff --no-index X Y" is run the modes of the files being differ are normalized by canon_mode() in fill_filespec(). I recently broke that behavior in a patch of mine[1] which would pass all tests, or not, depending on the umask of the git.git checkout. Let's test for this explicitly. Arguably this should not be the behavior of "git diff --no-index". We aren't diffing our own objects or the index, so it might be useful to show mode differences between files. On the other hand diff(1) does not do that, and it would be needlessly distracting when e.g. diffing an extracted tar archive whose contents is the same, but whose file modes are different. 1. https://lore.kernel.org/git/20210316155829.31242-2-avarab@gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-03-22pack-bitmap: avoid traversal of objects referenced by uninteresting tagLibravatar Patrick Steinhardt1-0/+14
When preparing the bitmap walk, we first establish the set of of have and want objects by iterating over the set of pending objects: if an object is marked as uninteresting, it's declared as an object we already have, otherwise as an object we want. These two sets are then used to compute which transitively referenced objects we need to obtain. One special case here are tag objects: when a tag is requested, we resolve it to its first not-tag object and add both resolved objects as well as the tag itself into either the have or want set. Given that the uninteresting-property always propagates to referenced objects, it is clear that if the tag is uninteresting, so are its children and vice versa. But we fail to propagate the flag, which effectively means that referenced objects will always be interesting except for the case where they have already been marked as uninteresting explicitly. This mislabeling does not impact correctness: we now have it in our "wants" set, and given that we later do an `AND NOT` of the bitmaps of "wants" and "haves" sets it is clear that the result must be the same. But we now start to needlessly traverse the tag's referenced objects in case it is uninteresting, even though we know that each referenced object will be uninteresting anyway. In the worst case, this can lead to a complete graph walk just to establish that we do not care for any object. Fix the issue by propagating the `UNINTERESTING` flag to pointees of tag objects and add a benchmark with negative revisions to p5310.

When the tool is invoked with "start-daemon", it spawns a "run-daemon" command in the background and waits for the server to become ready before exiting. (This helps make unit tests in t0052 more predictable and avoids the need for arbitrary sleeps in the test script.)

2021-03-19builtin/pack-objects.c: ignore missing links with --stdin-packsLibravatar Taylor Blau1-0/+38
When 'git pack-objects --stdin-packs' encounters a commit in a pack, it marks it as a starting point of a best-effort reachability traversal that is used to populate the name-hash of the objects listed in the given packs. The traversal expects that it should be able to walk the ancestors of all commits in a pack without issue. Ordinarily this is the case, but it is possible to having missing parents from an unreachable part of the repository. In that case, we'd consider any missing objects in the unreachable portion of the graph to be junk. This should be handled gracefully: since the traversal is best-effort (i.e., we don't strictly need to fill in all of the name-hash fields), we should simply ignore any missing links. This patch does that (by setting the 'ignore_missing_links' bit on the rev_info struct), and ensures we don't regress in the future by adding a test which demonstrates this case. It is a little over-eager, since it will also ignore missing links in reachable parts of the packs (which would indicate a corrupted repository), but '--stdin-packs' is explicitly *not* about reachability. So this step isn't making anything worse for a repository which contains packs missing reachable objects (since we never drop objects with '--stdin-packs').

2021-03-18t: annotate !PTHREADS tests with !FAIL_PREREQSLibravatar Jeff King2-3/+6
Some tests in t5300 and t7810 expect us to complain about a "--threads" argument when Git is compiled without pthread support. Running these under GIT_TEST_FAIL_PREREQS produces a confusing failure: we pretend to the tests that there is no pthread support, so they expect the warning, but of course the actual build is perfectly happy to respect the --threads argument. We never noticed before the recent a926c4b904 (tests: remove most uses of C_LOCALE_OUTPUT, 2021-02-11), because the tests also were marked as requiring the C_LOCALE_OUTPUT prerequisite. Which means they'd never have run in FAIL_PREREQS mode, since it would always pretend that the locale prereq was not satisfied. These tests can't possibly work in this mode; it is a mismatch between what the tests expect and what the build was told to do. So let's just mark them to be skipped, using the special prereq introduced by dfe1a17df9 (tests: add a special setup where prerequisites fail, 2019-05-13).

2021-03-18checkout: don't follow symlinks when removing entriesLibravatar Matheus Tavares1-0/+12
At 1d718a5108 ("do not overwrite untracked symlinks", 2011-02-20), symlink.c:check_leading_path() started returning different codes for FL_ENOENT and FL_SYMLINK. But one of its callers, unlink_entry(), was not adjusted for this change, so it started to follow symlinks on the leading path of to-be-removed entries. Fix that and add a regression test. Note that since 1d718a5108 check_leading_path() no longer differentiates the case where it found a symlink in the path's leading components from the cases where it found a regular file or failed to lstat() the component. So, a side effect of this current patch is that unlink_entry() now returns early in all of these three cases. And because we no longer try to unlink such paths, we also don't get the warning from remove_or_warn(). For the regular file and symlink cases, it's questionable whether the warning was useful in the first place: unlink_entry() removes tracked paths that should no longer be present in the state we are checking out to. If the path had its leading dir replaced by another file, it means that the basename already doesn't exist, so there is no need for a warning. Sure, we are leaving a regular file or symlink behind at the path's dirname, but this file is either untracked now (so again, no need to warn), or it will be replaced by a tracked file during the next phase of this checkout operation. As for failing to lstat() one of the leading components, the basename might still exist only we cannot unlink it (e.g. due to the lack of the required permissions). Since the user expect it to be removed (especially with checkout's --no-overlay option), add back the warning in this more relevant case.

2021-03-17bisect: peel annotated tags to commitsLibravatar Jeff King1-0/+12
This patch fixes a bug where git-bisect doesn't handle receiving annotated tags as "git bisect good <tag>", etc. It's a regression in 27257bc466 (bisect--helper: reimplement `bisect_state` & `bisect_head` shell functions in C, 2020-10-15). The original shell code called: sha=$(git rev-parse --verify "$rev^{commit}") || die "$(eval_gettext "Bad rev input: \$rev")" which will peel the input to a commit (or complain if that's not possible). But the C code just calls get_oid(), which will yield the oid of the tag. The fix is to peel to a commit. The error message here is a little non-idiomatic for Git (since it starts with a capital). I've mostly left it, as it matches the other converted messages (like the "Bad rev input" we print when get_oid() fails), though I did add an indication that it was the peeling that was the problem. It might be worth taking a pass through this converted code to modernize some of the error messages. Note also that the test does a bare "grep" (not i18ngrep) on the expected "X is the first bad commit" output message. This matches the rest of the test script.

2021-03-17t5606: run clone branch name test with protocol v2Libravatar Jonathan Tan1-1/+1
4f37d45706 ("clone: respect remote unborn HEAD", 2021-02-05) introduces a new feature (if the remote has an unborn HEAD, e.g. when the remote repository is empty, use it as the name of the branch) that only works in protocol v2, but did not ensure that one of its tests always uses protocol v2, and thus that test would fail if GIT_TEST_PROTOCOL_VERSION=0 (or 1) is used. Therefore, add "-c protocol.version=2" to the appropriate test. (The rest of the tests from that commit have "-c protocol.version=2" already added.)
