2026-03-11t: allow use of "sed -E"Junio C Hamano
Since early 2019 with e62e225f (test-lint: only use only sed [-n] [-e command] [-f command_file], 2019-01-20), we have been trying to limit the options of "sed" we use in our tests to "-e <pattern>", "-n", and "-f <file>". Before the commit, we were trying to reject only "-i" (which is one of the really-not-portable options), but the commit explicitly wanted to reject use of "-E" (use ERE instead of BRE). The commit cites the then-current POSIX.1 (Issue 7, 2018 edition) to show that "even recent POSIX does not have it!", but the latest edition (Issue 8) documents "-E" as an option to use ERE. But that was 7 years ago, and that is a long time for many things to happen. Besides, we have been using "sed -E" without the check in question triggering in one of the scripts since 2022, with 461fec41 (bisect run: keep some of the post-v2.30.0 output, 2022-11-10). It was hidden because the 'E' was squished with another single letter option. t/t6030-bisect-porcelain.sh: sed -En 's/.*(bisect... This escaped the rather simple pattern used in the checker /\bsed\s+-[^efn]\s+/ and err 'sed option not portable...'; because -E did not appear as a singleton. Let's change the rule to allow the "-E" option, which nobody has complained against for the past 3 years. We rewrite our first use of the "-E" option so that it is caught by the old rule, primarily because we do not want to teach our mischievous developers how to smuggle in an unwanted option undetected by the test lint. And at the same time, loosen the pattern to allow "-E" the same way we allow "-n" and friends. Signed-off-by: Junio C Hamano <gitster@pobox.com>

"git merge-tree" has learned that the three trees involved in the 3-way merge only need to be trees, not necessarily commits. * js/merge-tree-3-trees: fill_tree_descriptor(): mark error message for translation cache-tree: avoid an unnecessary check Always check `parse_tree*()`'s return value t4301: verify that merge-tree fails on missing blob objects merge-ort: do check `parse_tree()`'s return value merge-tree: fail with a non-zero exit code on missing tree objects merge-tree: accept 3 trees as arguments
2024-02-23fill_tree_descriptor(): mark error message for translationJohannes Schindelin
There is an error message in that function to report a missing tree; In contrast to three other, similar error messages, it is not marked for translation yet. Mark it for translation, and while at it, make the error message consistent with the others by enclosing the SHA in parentheses. This requires a change to t6030 which expects the previous format of the commit message. Theoretically, this could present problems with existing scripts that use `git bisect` and parse its output (because Git does not provide other means for callers to discern between error conditions). However, this is unlikely to matter in practice because the most common course of action to deal with fatal corruptions is to report the error message to the user and exit, rather than trying to do something with the reported SHA of the missing tree.

2023-12-09bisect: always clean on resetJeff King
Usually "bisect reset" cleans up any refs/bisect/ refs, along with meta-files like .git/BISECT_LOG. But it only does so after deciding that a bisection is active, which it does by reading BISECT_START. This is usually fine, but it's possible to get into a confusing state if the BISECT_START file is gone, but other cruft is left (this might be due to a bug, or a system crash, etc). And since "bisect reset" refuses to do anything in this state, the user has no easy way to clean up the leftover cruft. While another "bisect start" would clear the state, in the interim it can be annoying, as other tools (like our bash prompt code) think we are bisecting, and for-each-ref output may be polluted with refs/bisect/ entries. Further adding to the confusion is that running "bisect reset $some_ref" skips the BISECT_START check. So it never realizes that there's no bisection active and does the cleanup anyway! So let's just make sure we always do the cleanup, whether we looked at BISECT_START or not. If the user doesn't give us a commit to reset to, we'll still say "We are not bisecting" and skip the call to "git checkout".

2023-11-02tests: teach callers of test_i18ngrep to use test_grepJunio C Hamano
They are equivalents and the former still exists, so as long as the only change this commit makes are to rewrite test_i18ngrep to test_grep, there won't be any new bug, even if there still are callers of test_i18ngrep remaining in the tree, or when merged to other topics that add new uses of test_i18ngrep. This patch was produced more or less with git grep -l -e 'test_i18ngrep ' 't/t[0-9][0-9][0-9][0-9]-*.sh' | xargs perl -p -i -e 's/test_i18ngrep /test_grep /' and a good way to sanity check the result yourself is to run the above in a checkout of c4603c1c (test framework: further deprecate test_i18ngrep, 2023-10-31) and compare the resulting working tree contents with the result of applying this patch to the same commit. You'll see that test_i18ngrep in a few t/lib-*.sh files corrected, in addition to the manual reproduction. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2023-01-22bisect: fix "reset" when branch is checked out elsewhereRubén Justo
Since 1d0fa89 (checkout: add --ignore-other-wortrees, 2015-01-03) we have a safety valve in checkout/switch to prevent the same branch from being checked out simultaneously in multiple worktrees. If a branch is bisected in a worktree while also being checked out in another worktree; when the bisection is finished, checking out the branch back in the current worktree may fail.

2023-01-13bisect: no longer try to clean up left-over `.git/head-name` filesJohannes Schindelin
As per the code comment, the `.git/head-name` files were cleaned up for backwards-compatibility: an old version of `git bisect` could have left them behind. Now, just how old would such a version be? As of 0f497e75f05 (Eliminate confusing "won't bisect on seeked tree" failure, 2008-02-23), `git bisect` does not write that file anymore. Which corresponds to Git v1.5.4.4. Even if the likelihood is non-nil that there might still be users out there who use such an old version to start a bisection, but then decide to continue bisecting with a current Git version, it is highly improbable. So let's remove that code, at long last.

2023-01-13bisect run: fix the error messageJohannes Schindelin
In d1bbbe45df8 (bisect--helper: reimplement `bisect_run` shell function in C, 2021-09-13), we ported the `bisect run` subcommand to C, including the part that prints out an error message when the implicit `git bisect bad` or `git bisect good` failed. However, the error message was supposed to print out whether the state was "good" or "bad", but used a bogus (because non-populated) `args` variable for it. This was fixed in [1], but as of [2] (when `bisect--helper` was changed to the present `bisect-state') the error message still talks about implementation details that should not concern end users. Fix that, and add a regression test to ensure that the intended form of the error message. 1. 80c2e9657f2 (bisect--helper: report actual bisect_state() argument on error, 2022-01-18 2. f37d0bdd42d (bisect: fix output regressions in v2.30.0, 2022-11-10) Helped-by: Elijah Newren <newren@gmail.com> Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Preceding commits fixed output and behavior regressions in d1bbbe45df8 (bisect--helper: reimplement `bisect_run` shell function in C, 2021-09-13), which did not claim to be changing the output of "git bisect run". But some of the output it emitted was subjectively better, so once we've asserted that we're back on v2.29.0 behavior, let's change some of it back: - We now quote the arguments again, but omit the first " " when printing the "running" line. - Ditto for other cases where we emitted the argument - We say "found first bad commit" again, not just "run success" Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Based-on-patch-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Đoàn Trần Công Danh <congdanhqx@gmail.com> Signed-off-by: Taylor Blau <me@ttaylorr.com>

When d1bbbe45df8 (bisect--helper: reimplement `bisect_run` shell function in C, 2021-09-13) reimplemented parts of "git bisect run" in C it changed the output we emitted so that: - The "running ..." line was now quoted - We lost the \n after our output - We started saying "bisect found ..." instead of "bisect run success" Arguably some of this is better now, but as d1bbbe45df8 did not advocate for changing the output, let's revert this for now. It'll be easy to change it back if that's what we'd prefer. This does not change the one remaining use of "command.buf" to emit the quoted argument, as that's new in d1bbbe45df8. Some of these cases were not tested for in the tests added in the preceding commit, I didn't have time to fleshen those out, but a look at f1de981e8b6 will show that the other output being adjusted here is now equivalent to what it was before d1bbbe45df8.

Add three failing tests which succeed on v2.29.0, but due to the topic merged at [1] (specifically [2]) have been failing since then. We'll address those regressions in subsequent commits. There was also a "regression" where: git bisect run ./missing-script.sh Would count a non-existing script as "good", as the shell would exit with 127. That edge case is a bit too insane to preserve, so let's not add it to these regression tests. There was another regression that 'git bisect' consumed some options that was meant to passed down to program run with 'git bisect run'. Since that regression is breaking user's expectation, it has been fixed earlier without this patch queued. 1. 0a4cb1f1f2f (Merge branch 'mr/bisect-in-c-4', 2021-09-23) 2. d1bbbe45df8 (bisect--helper: reimplement `bisect_run` shell function in C, 2021-09-13) Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Đoàn Trần Công Danh <congdanhqx@gmail.com> Signed-off-by: Taylor Blau <me@ttaylorr.com>

When we're running "git bisect run" with a command that expecting a "--log" or "--no-log" arguments, or one of those "--bisect-..." arguments, bisect--helper may mistakenly think those options are bisect--helper's option. We may fix those problems by passing "--" when calling from git-bisect.sh, and skip that "--" in bisect--helper. However, it may interfere with user's "--".

2022-05-11bisect: output state before we are ready to compute bisectionChris Down
Commit 73c6de06aff8 ("bisect: don't use invalid oid as rev when starting") changes the behaviour of `git bisect` to consider invalid oids as pathspecs again, as in the old shell implementation. While that behaviour may be desirable, it can also cause confusion. For example, while bisecting in a particular repo I encountered this: $ git bisect start d93ff48803f0 v6.3 $ ...which led to me sitting for a few moments, wondering why there's no printout stating the first rev to check. It turns out that the tag was actually "6.3", not "v6.3", and thus the bisect was still silently started with only a bad rev, because d93ff48803f0 was a valid oid and "v6.3" was silently considered to be a pathspec. While this behaviour may be desirable, it can be confusing, especially with different repo conventions either using or not using "v" before release names, or when a branch name or tag is simply misspelled on the command line. In order to avoid situations like this, make it more clear what we're waiting for: $ git bisect start d93ff48803f0 v6.3 status: waiting for good commit(s), bad commit known We already have good output once the bisect process has begun in earnest, so we don't need to do anything more there.

2022-01-19bisect--helper: double-check run command on exit code 126 and 127René Scharfe
When a run command cannot be executed or found, shells return exit code 126 or 127, respectively. Valid run commands are allowed to return these codes as well to indicate bad revisions, though, for historical reasons. This means typos can cause bogus bisect runs that go over the full distance and end up reporting invalid results. The best solution would be to reserve exit codes 126 and 127, like 71b0251cdd (Bisect run: "skip" current commit if script exit code is 125., 2007-10-26) did for 125, and abort bisect run when we get them. That might be inconvenient for those who relied on the documentation stating that 126 and 127 can be used for bad revisions, though. The workaround used by this patch is to run the command on a known-good revision and abort if we still get the same error code. This adds one step to runs with scripts that use exit codes 126 and 127, but keeps them supported, with one exception: It won't work with commands that cannot recognize the (manually marked) known-good revision as such. Run commands that use low exit codes are unaffected. Typos are reported after executing the missing command twice and three checkouts (the first step, the known good revision and back to the revision of the first step).

2021-04-30bisect--helper: use BISECT_TERMS in 'bisect skip' commandRamsay Jones
Commit e4c7b33747 ("bisect--helper: reimplement `bisect_skip` shell function in C", 2021-02-03), as part of the shell-to-C conversion, forgot to read the 'terms' file (.git/BISECT_TERMS) during the new 'bisect skip' command implementation. As a result, the 'bisect skip' command will use the default 'bad'/'good' terms. If the bisection terms have been set to non-default values (for example by the 'bisect start' command), then the 'bisect skip' command will fail. In order to correct this problem, we insert a call to the get_terms() function, which reads the non-default terms from that file (if set), in the '--bisect-skip' command implementation of 'bisect--helper'. Also, add a test[1] to protect against potential future regression.

2021-03-17bisect: peel annotated tags to commitsJeff King
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.

2020-11-19tests: mark tests relying on the current default for `init.defaultBranch`Johannes Schindelin
In addition to the manual adjustment to let the `linux-gcc` CI job run the test suite with `master` and then with `main`, this patch makes sure that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts that currently rely on the initial branch name being `master by default. To determine which test scripts to mark up, the first step was to force-set the default branch name to `master` in - all test scripts that contain the keyword `master`, - t4211, which expects `t/t4211/history.export` with a hard-coded ref to initialize the default branch, - t5560 because it sources `t/t556x_common` which uses `master`, - t8002 and t8012 because both source `t/annotate-tests.sh` which also uses `master`) This trick was performed by this command: $ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\ GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\ ' $(git grep -l master t/t[0-9]*.sh) \ t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh After that, careful, manual inspection revealed that some of the test scripts containing the needle `master` do not actually rely on a specific default branch name: either they mention `master` only in a comment, or they initialize that branch specificially, or they do not actually refer to the current default branch. Therefore, the aforementioned modification was undone in those test scripts thusly: $ git checkout HEAD -- \ t/t0027-auto-crlf.sh t/t0060-path-utils.sh \ t/t1011-read-tree-sparse-checkout.sh \ t/t1305-config-include.sh t/t1309-early-config.sh \ t/t1402-check-ref-format.sh t/t1450-fsck.sh \ t/t2024-checkout-dwim.sh \ t/t2106-update-index-assume-unchanged.sh \ t/t3040-subprojects-basic.sh t/t3301-notes.sh \ t/t3308-notes-merge.sh t/t3423-rebase-reword.sh \ t/t3436-rebase-more-options.sh \ t/t4015-diff-whitespace.sh t/t4257-am-interactive.sh \ t/t5323-pack-redundant.sh t/t5401-update-hooks.sh \ t/t5511-refspec.sh t/t5526-fetch-submodules.sh \ t/t5529-push-errors.sh t/t5530-upload-pack-error.sh \ t/t5548-push-porcelain.sh \ t/t5552-skipping-fetch-negotiator.sh \ t/t5572-pull-submodule.sh t/t5608-clone-2gb.sh \ t/t5614-clone-submodules-shallow.sh \ t/t7508-status.sh t/t7606-merge-custom.sh \ t/t9302-fast-import-unpack-limit.sh We excluded one set of test scripts in these commands, though: the range of `git p4` tests. The reason? `git p4` stores the (foreign) remote branch in the branch called `p4/master`, which is obviously not the default branch. Manual analysis revealed that only five of these tests actually require a specific default branch name to pass; They were modified thusly: $ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\ GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\ ' t/t980[0167]*.sh t/t9811*.sh Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-09-25bisect: don't use invalid oid as rev when startingChristian Couder
In 06f5608c14 (bisect--helper: `bisect_start` shell function partially in C, 2019-01-02), we changed the following shell code: - rev=$(git rev-parse -q --verify "$arg^{commit}") || { - test $has_double_dash -eq 1 && - die "$(eval_gettext "'\$arg' does not appear to be a valid revision")" - break - } - revs="$revs $rev" into: + char *commit_id = xstrfmt("%s^{commit}", arg); + if (get_oid(commit_id, &oid) && has_double_dash) + die(_("'%s' does not appear to be a valid " + "revision"), arg); + + string_list_append(&revs, oid_to_hex(&oid)); + free(commit_id); In case of an invalid "arg" when "has_double_dash" is false, the old code would "break" out of the argument loop. In the new C code though, `oid_to_hex(&oid)` is unconditonally appended to "revs". This is wrong first because "oid" is junk as `get_oid(commit_id, &oid)` failed and second because it doesn't break out of the argument loop. Not breaking out of the argument loop means that "arg" is then not treated as a path restriction (which is wrong).

2020-08-07bisect: introduce first-parent flagAaron Lipman
Upon seeing a merge commit when bisecting, this option may be used to follow only the first parent. In detecting regressions introduced through the merging of a branch, the merge commit will be identified as introduction of the bug and its ancestors will be ignored. This option is particularly useful in avoiding false positives when a merged branch contained broken or non-buildable commits, but the merge itself was OK.

06f5608c14 (bisect--helper: `bisect_start` shell function partially in C, 2019-01-02) adds a lax parser for `git bisect start` which could result in a segfault under a bad syntax call for start with custom terms. Detect if there are enough arguments left in the command line to use for --term-{old,good,new,bad} and abort with the same syntax error the original implementation will show if not. While at it, remove an unnecessary (and incomplete) check for unknown arguments and make sure to add a test to avoid regressions.

We advertise that the bisect log can be corrected in your editor before being fed to "git bisect replay", but some editors may turn the line endings to CRLF. Update the parser of the input lines so that the CR at the end of the line gets ignored. Were anyone to intentionally be using terms/revs with embedded CRs, replaying such bisects will no longer work with this change. I suspect that this is incredibly rare.

2019-07-01t6030: make test work with SHA-256brian m. carlson
Compute several object ID values instead of hard-coding them, and use test_oid_to_path to cleanly produce a path for an object. Note that the bisect code which is tested here remains sensitive to the hash algorithm in use because it uses the object ID to disambiguate between two equidistant commits. Fortunately, SHA-1 and SHA-256 disambiguate identically in the cases we care about, so there is no need to modify the test to accommodate this situation. However, if a further hash algorithm change occurs, this test may require some restructuring.

2019-03-01bisect: make diff-tree output prettierJeff King
After completing a bisection, we print out the commit we found using an internal version of diff-tree. The result is aesthetically lacking: - it shows a raw diff, which is generally less informative for human readers than "--stat --summary" (which we already decided was nice for humans in format-patch's output). - by not abbreviating hashes, the result is likely to wrap on most people's terminals - we don't use "-r", so if the commit touched files in a directory, you only get to see the top-level directory mentioned - we don't specify "--cc" or similar, so merges print nothing (not even the commit message!) Even though bisect might be driven by scripts, there's no reason to consider this part of the output as machine-readable (if anything, the initial "$hash is the first bad commit" might be parsed, but we won't touch that here). Let's make it prettier and more informative for a human reading the output. While we're tweaking the options, let's also switch to using the diff "ui" config. If we're accepting that this is human-readable output, then we should respect the user's options for how to display it. Note that we have to touch a few tests in t6030. These check bisection in a corrupted repository (it's missing a subtree). They didn't fail with the previous code, because it didn't actually recurse far enough in the diff to find the broken tree. But now we'll see the corruption and complain. Adjusting the tests to expect the die() is the best fix. We still confirm that we're able to bisect within the broken repo. And we'll still print "$hash is the first bad commit" as usual before dying; showing that is a reasonable outcome in a corrupt repository (and was what might happen already, if the root tree was corrupt).

2019-01-02bisect--helper: `get_terms` & `bisect_terms` shell function in CPranit Bauva
Reimplement the `get_terms` and `bisect_terms` shell function in C and add `bisect-terms` subcommand to `git bisect--helper` to call it from git-bisect.sh . Using `--bisect-terms` subcommand is a temporary measure to port shell function in C so as to use the existing test suite. As more functions are ported, this subcommand will be retired but its implementation will be called by some other methods. Also use error() to report "no terms defined" and accordingly change the test in t6030. We need to use PARSE_OPT_KEEP_UNKNOWN here to allow for parameters that look like options (e.g --term-good) but should not be parsed by cmd_bisect__helper(). This change is safe because all other cmdmodes have strict argc checks already.
