"core.commentChar=auto" that attempts to dynamically pick a suitable comment character is non-workable, as it is too much trouble to support for little benefit, and is marked as deprecated. * pw/3.0-commentchar-auto-deprecation: commit: print advice when core.commentString=auto config: warn on core.commentString=auto breaking-changes: deprecate support for core.commentString=auto
2025-08-26config: warn on core.commentString=autoPhillip Wood
As support for this setting was deprecated in the last commit print a warning (or die when WITH_BREAKING_CHANGES is enabled) if it is set. Avoid bombarding the user with warnings by only printing it (a) when running commands that call "git commit" and (b) only once per command. Some scaffolding is added to repo_read_config() to allow it to detect deprecated config settings and warn about them. As both "core.commentChar" and "core.commentString" set the comment character we record which one of them is used and tailor the warning message appropriately. Note the odd combination of die_message() followed by die(NULL) is to allow the next commit to insert a call to advise() in the middle.

Squelch false-positive compiler warning. * jk/revert-squelch-compiler-warning: revert: initialize const value
2025-08-04revert: initialize const valueJeff King
When building with clang-22 and DEVELOPER=1 mode, this warning causes us to fail compilation: builtin/revert.c:114:13: error: default initialization of an object of type 'const char' leaves the object uninitialized [-Werror,-Wdefault-const-init-var-unsafe] 114 | const char sentinel_value; | ^ The compiler is right that this code is a bit funny. We declare a const value without an initializer. It cannot be assigned to because of the const, but without an initializer it has no predictable value. So as a variable it can never have any useful function, and if we tried to look at it, we'd get undefined behavior. But it does have a function. We never use its value, but rather use its address as a sentinel value for some other variables: const char *gpg_sign = &sentinel_value; ...maybe set gpg_sign via parse_options... if (gpg_sign != &sentinel_value) ...we got a non-default value... Normally we'd use NULL as a sentinel value for a pointer, but it doesn't work here because we also want to detect --no-gpg-sign, which is marked by setting the pointer to NULL. We need a separate "this was not touched" value, which is what this sentinel variable gives us. So the code is correct as-is, but the sentinel variable itself is funny enough that it's understandable for a compiler warning to flag it. Let's try to appease the compiler. There are a few possible options: 1. Instead of a variable, we could just construct an artificial sentinel address like "1", "-1", etc. I think these technically fall afoul of the C standard (even if we do not access them, even constructing invalid pointers is not always allowed). But it's also something we do elsewhere, and even happens in some standard interfaces (e.g., mmap()'s MMAP_FAILED value). It does involve some annoying casts, though. 2. We can mark it as static. That gives it a definite value, but perhaps makes people wonder if the static-ness is important, when it's not. 3. We can just give it a value to shut the compiler up, even though nobody cares about that value. I went with (3) here as the smallest and most obvious change.

2025-04-17global: use designated initializers for optionsPatrick Steinhardt
While we expose macros for most of our different option types understood by the "parse-options" subsystem, not every combination of fields that has one as that would otherwise quickly lead to an explosion of macros. Instead, we just initialize structures manually for those variants of fields that don't have a macro. Callsites that open-code these structure initialization don't use designated initializers though and instead just provide values for each of the fields that they want to initialize. This has three significant downsides: - Callsites need to specify all values up to the last field that they care about. This often includes fields that should simply be left at their default zero-initialized state, which adds distraction. - Any reader not deeply familiar with the layout of the structure has a hard time figuring out what the respective initializers mean. - Reordering or introducing new fields in the middle of the structure is impossible without adapting all callsites. Convert all sites to instead use designated initializers, which we have started using in our codebase quite a while ago. This allows us to skip any default-initialized fields, gives the reader context by specifying the field names and allows us to reorder or introduce new fields where we want to.

2024-12-06diff.h: fix index used to loop through unsigned integerPatrick Steinhardt
The `struct diff_flags` structure is essentially an array of flags, all of which have the same type. We can thus use `sizeof()` to iterate through all of the flags, which we do in `diff_flags_or()`.

2024-09-30builtin/revert: fix leaking `gpg_sign` and `strategy` configPatrick Steinhardt
We leak the config values when `gpg_sign` or `strategy` options are being overridden via the command line. To fix this we need to free the old value, which requires us to figure out whether the value was changed via an option in the first place. The easy way to do this, which is to initialize local variables with `NULL`, doesn't work because we cannot tell the case where the user has passed e.g. `--no-gpg-sign`. Instead, we use a sentinel value for both values that we can compare against to check whether the user has passed the option.

2024-03-25cherry-pick: add `--empty` for more robust redundant commit handlingBrian Lyles
As with git-rebase(1) and git-am(1), git-cherry-pick(1) can result in a commit being made redundant if the content from the picked commit is already present in the target history. However, git-cherry-pick(1) does not have the same options available that git-rebase(1) and git-am(1) have. There are three things that can be done with these redundant commits: drop them, keep them, or have the cherry-pick stop and wait for the user to take an action. git-rebase(1) has the `--empty` option added in commit e98c4269c8 (rebase (interactive-backend): fix handling of commits that become empty, 2020-02-15), which handles all three of these scenarios. Similarly, git-am(1) got its own `--empty` in 7c096b8d61 (am: support --empty=<option> to handle empty patches, 2021-12-09). git-cherry-pick(1), on the other hand, only supports two of the three possiblities: Keep the redundant commits via `--keep-redundant-commits`, or have the cherry-pick fail by not specifying that option. There is no way to automatically drop redundant commits. In order to bring git-cherry-pick(1) more in-line with git-rebase(1) and git-am(1), this commit adds an `--empty` option to git-cherry-pick(1). It has the same three options (keep, drop, and stop), and largely behaves the same. The notable difference is that for git-cherry-pick(1), the default will be `stop`, which maintains the current behavior when the option is not specified. Like the existing `--keep-redundant-commits`, `--empty=keep` will imply `--allow-empty`. The `--keep-redundant-commits` option will be documented as a deprecated synonym of `--empty=keep`, and will be supported for backwards compatibility for the time being.

2023-04-10sequencer: use struct strvec to store merge strategy optionsPhillip Wood
The sequencer stores the merge strategy options in an array of strings which allocated with ALLOC_GROW(). Using "struct strvec" avoids manually managing the memory of that array and simplifies the code. Aside from memory allocation the changes to the sequencer are largely mechanical, changing xopts_nr to xopts.nr and xopts[i] to xopts.v[i]. A new option parsing macro OPT_STRVEC() is also added to collect the strategy options. Hopefully this can be used to simplify the code in builtin/merge.c in the future. Note that there is a change of behavior to "git cherry-pick" and "git revert" as passing “--no-strategy-option” will now clear any previous strategy options whereas before this change it did nothing.

2023-02-06sequencer API users: fix get_replay_opts() leaksÆvar Arnfjörð Bjarmason
Make the replay_opts_release() function added in the preceding commit non-static, and use it for freeing the "struct replay_opts" constructed for "rebase" and "revert". To safely call our new replay_opts_release() we'll need to stop calling it in sequencer_remove_state(), and instead call it where we allocate the "struct replay_opts" itself. This is because in e.g. do_interactive_rebase() we construct a "struct replay_opts" with "get_replay_opts()", and then call "complete_action()". If we get far enough in that function without encountering errors we'll call "pick_commits()" which (indirectly) calls sequencer_remove_state() at the end. But if we encounter errors anywhere along the way we'd punt out early, and not free() the memory we allocated. Remembering whether we previously called sequencer_remove_state() would be a hassle. Using a FREE_AND_NULL() pattern would also work, as it would be safe to call replay_opts_release() repeatedly. But let's fix this properly instead, by having the owner of the data free() it.

2022-05-31revert: --reference should apply only to 'revert', not 'cherry-pick'Junio C Hamano
As 'revert' and 'cherry-pick' share a lot of code, it is easy to modify the behaviour of one command and inadvertently affect the other. An earlier change to teach the '--reference' option and the 'revert.reference' configuration variable to the former was not careful enough and 'cherry-pick --reference' wasn't rejected as an error. It is possible to think 'cherry-pick -x' might benefit from the '--reference' option, but it is fundamentally different from 'revert' in at least two ways to make it questionable: - 'revert' names a commit that is ancestor of the resulting commit, so an abbreviated object name with human readable title is sufficient to identify the named commit uniquely without using the full object name. On the other hand, 'cherry-pick' usually [*] picks a commit that is not an ancestor. It might be even picking a private commit that never becomes part of the public history. - The whole commit message of 'cherry-pick' is a copy of the original commit, and there is nothing gained to repeat only the title part on 'cherry-picked from' message. [*] well, you could revert and then you can pick the original that was reverted to get back to where you were, but then you can revert the revert to do the same thing.

2022-05-26revert: optionally refer to commit in the "reference" formatJunio C Hamano
A typical "git revert" commit uses the full title of the original commit in its title, and starts its body of the message with: This reverts commit 8fa7f667cf61386257c00d6e954855cc3215ae91. This does not encourage the best practice of describing not just "what" (i.e. "Revert X" on the title says what we did) but "why" (i.e. and it does not say why X was undesirable). We can instead phrase this first line of the body to be more like This reverts commit 8fa7f667 (do this and that, 2022-04-25) so that the title does not have to be Revert "do this and that" We can instead use the title to describe "why" we are reverting the original commit. Introduce the "--reference" option to "git revert", and also the revert.reference configuration variable, which defaults to false, to tweak the title and the first line of the draft commit message for when creating a "revert" commit. When this option is in use, the first line of the pre-filled editor buffer becomes a comment line that tells the user to say _why_. If the user exits the editor without touching this line by mistake, what we prepare to become the first line of the body, i.e. "This reverts commit 8fa7f667 (do this and that, 2022-04-25)", ends up to be the title of the resulting commit. This behaviour is designed to help such a user to identify such a revert in "git log --oneline" easily so that it can be further reworded with "git rebase -i" later.

2021-03-31sequencer: fix edit handling for cherry-pick and revert messagesElijah Newren
save_opts() should save any non-default values. It was intended to do this, but since most options in struct replay_opts default to 0, it only saved non-zero values. Unfortunately, this does not always work for options.edit. Roughly speaking, options.edit had a default value of 0 for cherry-pick but a default value of 1 for revert. Make save_opts() record a value whenever it differs from the default. options.edit was also overly simplistic; we had more than two cases. The behavior that previously existed was as follows: Non-conflict commits Right after Conflict revert Edit iff isatty(0) Edit (ignore isatty(0)) cherry-pick No edit See above Specify --edit Edit (ignore isatty(0)) See above Specify --no-edit (*) See above (*) Before stopping for conflicts, No edit is the behavior. After stopping for conflicts, the --no-edit flag is not saved so see the first two rows. However, the expected behavior is: Non-conflict commits Right after Conflict revert Edit iff isatty(0) Edit iff isatty(0) cherry-pick No edit Edit iff isatty(0) Specify --edit Edit (ignore isatty(0)) Edit (ignore isatty(0)) Specify --no-edit No edit No edit In order to get the expected behavior, we need to change options.edit to a tri-state: unspecified, false, or true. When specified, we follow what it says. When unspecified, we need to check whether the current commit being created is resolving a conflict as well as consulting options.action and isatty(0). While at it, add a should_edit() utility function that compresses options.edit down to a boolean based on the additional information for the non-conflict case. continue_single_pick() is the function responsible for resuming after conflict cases, regardless of whether there is one commit being picked or many. Make this function stop assuming edit behavior in all cases, so that it can correctly handle !isatty(0) and specific requests to not edit the commit message.

2020-11-02merge,rebase,revert: select ort or recursive by config or environmentElijah Newren
Allow the testsuite to run where it treats requests for "recursive" or the default merge algorithm via consulting the environment variable GIT_TEST_MERGE_ALGORITHM which is expected to either be "recursive" (the old traditional algorithm) or "ort" (the new algorithm). Also, allow folks to pick the new algorithm via config setting. It turns out builtin/merge.c already had a way to allow users to specify a different default merge algorithm: pull.twohead. Rather odd configuration name (especially to be in the 'pull' namespace rather than 'merge') but it's there. Add that same configuration to rebase, cherry-pick, and revert. This required updating the various callsites that called merge_trees() or merge_recursive() to conditionally call the new API, so this serves as another demonstration of what the new API looks and feels like. There are almost certainly some callsites that have not yet been modified to work with the new merge algorithm, but this represents the ones that I have been testing with thus far.

2020-10-20Documentation: stylistically normalize references to Signed-off-by:Bradley M. Kuhn
Ted reported an old typo in the git-commit.txt and merge-options.txt. Namely, the phrase "Signed-off-by line" was used without either a definite nor indefinite article. Upon examination, it seems that the documentation (including items in Documentation/, but also option help strings) have been quite inconsistent on usage when referring to `Signed-off-by`. First, very few places used a definite or indefinite article with the phrase "Signed-off-by line", but that was the initial typo that led to this investigation. So, normalize using either an indefinite or definite article consistently. The original phrasing, in Commit 3f971fc425b (Documentation updates, 2005-08-14), is "Add Signed-off-by line". Commit 6f855371a53 (Add --signoff, --check, and long option-names. 2005-12-09) switched to using "Add `Signed-off-by:` line", but didn't normalize the former commit to match. Later commits seem to have cut and pasted from one or the other, which is likely how the usage became so inconsistent. Junio stated on the git mailing list in <xmqqy2k1dfoh.fsf@gitster.c.googlers.com> a preference to leave off the colon. Thus, prefer `Signed-off-by` (with backticks) for the documentation files and Signed-off-by (without backticks) for option help strings. Additionally, Junio argued that "trailer" is now the standard term to refer to `Signed-off-by`, saying that "becomes plenty clear that we are not talking about any random line in the log message". As such, prefer "trailer" over "line" anywhere the former word fits. However, leave alone those few places in documentation that use Signed-off-by to refer to the process (rather than the specific trailer), or in places where mail headers are generally discussed in comparison with Signed-off-by.

2019-07-02cherry-pick/revert: add --skip optionRohit Ashiwal
git am or rebase have a --skip flag to skip the current commit if the user wishes to do so. During a cherry-pick or revert a user could likewise skip a commit, but needs to use 'git reset' (or in the case of conflicts 'git reset --merge'), followed by 'git (cherry-pick | revert) --continue' to skip the commit. This is more annoying and sometimes confusing on the users' part. Add a `--skip` option to make skipping commits easier for the user and to make the commands more consistent. In the next commit, we will change the advice messages hence finishing the process of teaching revert and cherry-pick "how to skip commits".

2019-04-02checkout: inform the user when removing branch stateNguyễn Thái Ngọc Duy
After a successful switch, if a merge, cherry-pick or revert is ongoing, it is canceled. This behavior has been with us from the very early beginning, soon after git-merge was created but never actually documented [1]. It may be a good idea to be transparent and tell the user if some operation is canceled. I consider this a better way of telling the user than just adding a sentence or two in git-checkout.txt, which will be mostly ignored anyway. PS. Originally I wanted to print more details like warning: cancelling an in-progress merge from <SHA-1> which may allow some level of undo if the user wants to. But that seems a lot more work. Perhaps it can be improved later if people still want that. [1] ... and I will try not to argue whether it is a sensible behavior.

Note that the_hash_algo stays, even if we can easily replace it with repo->hash_algo. My reason is I still believe tying hash_algo to a struct repository is a wrong move.
