2021-11-19ssh signing: make sign/amend test more resilientLibravatar Fabian Stelzer2-2/+2
The test `amending already signed commit` is using git checkout to select a specific commit to amend. In case an earlier test fails and leaves behind a dirty index/worktree this test would fail as well. Using `checkout -f` will avoid interference by most other tests.

2021-11-19ssh signing: support non ssh-* keytypesLibravatar Fabian Stelzer2-1/+26
The user.signingKey config for ssh signing supports either a path to a file containing the key or for the sake of convenience a literal string with the ssh public key. To differentiate between those two cases we check if the first few characters contain "ssh-" which is unlikely to be the start of a path. ssh supports other key types which are not prefixed with "ssh-" and will currently be treated as a file path and therefore fail to load. To remedy this we move the prefix check into its own function and introduce the prefix `key::` for literal ssh keys. This way we don't need to add new key types when they become available. The existing `ssh-` prefix is retained for compatibility with current user configs but removed from the official documentation to discourage its use.

2021-11-11object-file: fix SEGV on free() regression in v2.34.0-rc2Libravatar Ævar Arnfjörð Bjarmason1-0/+8
Fix a regression introduced in my 96e41f58fe1 (fsck: report invalid object type-path combinations, 2021-10-01). When fsck-ing blobs larger than core.bigFileThreshold, we'd free() a pointer to uninitialized memory. This issue would have been caught by SANITIZE=address, but since it involves core.bigFileThreshold, none of the existing tests in our test suite covered it. Running them with the "big_file_threshold" in "environment.c" changed to say "6" would have shown this failure, but let's add a dedicated test for this scenario based on Han Xin's report[1]. The bug was introduced between v9 and v10[2] of the fsck series merged in 061a21d36d8 (Merge branch 'ab/fsck-unexpected-type', 2021-10-25). 1. https://lore.kernel.org/git/20211111030302.75694-1-hanxin.hx@alibaba-inc.com/ 2. https://lore.kernel.org/git/cover-v10-00.17-00000000000-20211001T091051Z-avarab@gmail.com/ Reported-by: Han Xin <chiyutianyi@gmail.com> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2021-11-10t/lib-gpg: avoid broken versions of ssh-keygenLibravatar Jeff King1-0/+6
The "-Y find-principals" option of ssh-keygen seems to be broken in Debian's openssh-client 1:8.7p1-1, whereas it works fine in 1:8.4p1-5. This causes several failures for GPGSSH tests. We fulfill the prerequisite because generating the keys works fine, but actually verifying a signature causes results ranging from bogus results to ssh-keygen segfaulting. We can find the broken version during the prereq check by feeding it empty input. This should result in it complaining to stderr, but in the broken version it triggers the segfault, causing the GPGSSH tests to be skipped.

2021-11-05t/lib-git.sh: fix ACL-related permissions failureLibravatar Adam Dinwoodie1-0/+1
As well as checking that the relevant functionality is available, the GPGSSH prerequisite check creates the SSH keys that are used by the test functions it gates. If these keys are created in a directory that has a default Access Control List, the key files can inherit those permissions. This can result in a scenario where the private keys are created successfully, so the prerequisite check passes and the tests are run, but the key files have permissions that are too permissive, meaning OpenSSH will refuse to load them and the tests will fail. To avoid this happening, before creating the keys, clear any default ACL set on the directory that will contain them. This step allowed to fail; if setfacl isn't present, that's a very likely indicator that the filesystem in question simply doesn't support default ACLs.

2021-11-03dir: fix directory-matching bugLibravatar Derrick Stolee1-0/+26
This reverts the change from ed49584 (dir: fix pattern matching on dirs, 2021-09-24), which claimed to fix a directory-matching problem without a test case. It turns out to _create_ a bug, but it is a bit subtle. The bug would have been revealed by the first of two tests being added to t0008-ignores.sh. The first uses a pattern "/git/" inside the a/.gitignores file, which matches against 'a/git/foo' but not 'a/git-foo/bar'. This test would fail before the revert. The second test shows what happens if the test instead uses a pattern "git/" and this test passes both before and after the revert. The difference in these two cases are due to how last_matching_pattern_from_list() checks patterns both if they have the PATTERN_FLAG_MUSTBEDIR and PATTERN_FLAG_NODIR flags. In the case of "git/", the PATTERN_FLAG_NODIR is also provided, making the change in behavior in match_pathname() not affect the end result of last_matching_pattern_from_list().

2021-10-29pull: --ff-only should make it a noop when already-up-to-dateLibravatar Junio C Hamano1-1/+15
Earlier, we made sure that "git pull --ff-only" (and "git -c pull.ff=only pull") errors out when our current HEAD is not an ancestor of the tip of the history we are merging, but the condition to trigger the error was implemented incorrectly. Imagine you forked from a remote branch, built your history on top of it, and then attempted to pull from them again. If they have not made any update in the meantime, our current HEAD is obviously not their ancestor, and this new error triggers. Without the --ff-only option, we just report that there is no need to pull; we did the same historically with --ff-only, too. Make sure we do not fail with the recently added check to restore the historical behaviour.

2021-10-28add, rm, mv: fix bug that prevents the update of non-sparse dirsLibravatar Matheus Tavares3-5/+73
These three commands recently learned to avoid updating paths outside the sparse checkout even if they are missing the SKIP_WORKTREE bit. This is done using path_in_sparse_checkout(), which checks whether a given path matches the current list of sparsity rules, similar to what clear_ce_flags() does when we run "git sparse checkout init" or "git sparse-checkout reapply". However, clear_ce_flags() uses a recursive approach, applying the match results from parent directories on paths that get the UNDECIDED result, whereas path_in_sparse_checkout() only attempts to match the full path and immediately considers UNDECIDED as NOT_MATCHED. This makes the function miss matches with leading directories. For example, if the user has the sparsity patterns "!/a" and "b/", add, rm, and mv will fail to update the path "a/b/c" and end up displaying a warning about it being outside the sparse checkout even though it isn't. This problem only occurs in full pattern mode as the pattern matching functions never return UNDECIDED for cone mode. To fix this, replicate the recursive behavior of clear_ce_flags() in path_in_sparse_checkout(), falling back to the parent directory match when a path gets the UNDECIDED result. (If this turns out to be too expensive in some cases, we may want to later add some form of caching to accelerate multiple queries within the same directory. This is not implemented in this patch, though.) Also add two tests for each affected command (add, rm, and mv) to check that they behave correctly with the recursive pattern matching. The first test would previously fail without this patch while the second already succeeded. It is added mostly to make sure that we are not breaking the existing pattern matching for directories that are really sparse, and also as a protection against any future regressions. Two other existing tests had to be changed as well: one test in t3602 checks that "git rm -r <dir>" won't remove sparse entries, but it didn't allow the non-sparse entries inside <dir> to be removed. The other one, in t7002, tested that "git mv" would correctly display a warning message for sparse paths, but it accidentally expected the message to include two non-sparse paths as well.

2021-10-25userdiff-cpp: back out the digit-separators in numbersLibravatar Johannes Sixt3-15/+15
The implementation of digit-separating single-quotes introduced a note-worthy regression: the change of a character literal with a digit would splice the digit and the closing single-quote. For example, the change from 'a' to '2' is now tokenized as '[-a'-]{+2'+} instead of '[-a-]{+2+}'. The options to fix the regression are: - Tighten the regular expression such that the single-quote can only occur between digits (that would match the official syntax). - Remove support for digit separators. I chose to remove support, because - I have not seen a lot of code make use of digit separators. - If code does use digit separators, then the numbers are typically long. If a change in one of the segments occurs, it is actually better visible if only that segment is highlighted as the word that changed instead of the whole long number. This choice does introduce another minor regression, though, which is highlighted in the test case: when a change occurs in the second or later segment of a hexadecimal number where the segment begins with a digit, but also has letters, the segment is mistaken as consisting of a number and an identifier. I can live with that. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
