Some places in the code confused a variable that is *not* a boolean to enable color but is an enum that records what the user requested to do about color.

2025-09-16color: use git_colorbool enum type to store colorboolsJeff King1-1/+1
We traditionally used "int" to store and pass around the values defined by "enum git_colorbool" (which were originally just #define macros). Using an int doesn't produce incorrect results, but using the actual enum makes the intent of the code more clear. It would be nice if the compiler could catch cases where we used the enum and an int interchangeably, since it's very easy to accidentally check the boolean true/false of a colorbool like: if (branch_use_color) This is wrong because GIT_COLOR_UNKNOWN and GIT_COLOR_AUTO evaluate to true in C, even though we may ultimately decide not to use color. But C is pretty happy to convert between ints and enums (even with various -Wenum-* warnings). So this sadly doesn't protect us from such mistakes, but it hopefully does make the code easier to read.

2025-09-16color: use GIT_COLOR_* instead of numeric constantsJeff King1-1/+1
Long ago Git's decision to show color for a subsytem was stored in a tri-state variable: it could be true (1), false (0), or unknown (-1). But since daa0c3d971 (color: delay auto-color decision until point of use, 2011-08-17) we want to carry around a new state, "auto", which bases the decision on the tty-ness of stdout (rather than collapsing that "auto" state to a true/false immediately). That commit introduced a set of GIT_COLOR_* defines to represent each state: UNKNOWN, ALWAYS, NEVER, and AUTO. But it only used the AUTO value, and left alone code using bare 0/1/-1 values. And of course since then we've grown many new spots that use those bare values. Let's switch all of these to use the named constants. That should make the code a bit easier to read, as it is more obvious that we're representing a color decision.

2025-08-26config: warn on core.commentString=autoPhillip Wood1-0/+3
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.

2025-08-26breaking-changes: deprecate support for core.commentString=autoPhillip Wood1-0/+4
When "core.commentString" is set to "auto" then "git commit" will automatically select the comment character ensuring that it is not the first character on any of the lines in the commit message. This was introduced by commit 84c9dc2c5a2 (commit: allow core.commentChar=auto for character auto selection, 2014-05-17). The motivation seems to be to avoid commenting out lines from the existing message when amending a commit that was created with a message from a file. Unfortunately this feature does not work with: * commit message templates that contain comments. * prepare-commit-msg hooks that introduce comments. * "git commit --cleanup=strip --edit -F <file>" which means that it is incompatible with - the "fixup" and "squash" commands of "git rebase -i" as the comments added by those commands are then treated as part of the commit message. - the conflict comments added to the commit message by "git cherry-pick", "git rebase" etc. as these comments are then treated as part of the commit message. It is also ignored by "git notes" when amending a note. The issues with comments coming from a template, hook or file are a consequence of the design of this feature and are therefore hard to fix. As the costs of this feature outweigh the benefits, deprecate it and remove it in Git 3.0. If someone comes up with some patches that fix all the issues in a maintainable way then I'd be happy to see this change reverted. The next commits will add a warning and some advice for users on how they can update their config settings.

2025-07-29add-patch: add diff.context command line overridesLeon Michalak1-1/+15
This patch compliments the previous commit, where builtins that use add-patch infrastructure now respect diff.context and diff.interHunkContext file configurations. In particular, this patch helps users who don't want to set persistent context configurations or just want a way to override them on a one-time basis, by allowing the relevant builtins to accept corresponding command line options that override the file configurations. This mimics commands such as diff and log, which allow for both context file configuration and command line overrides.

2025-07-23config: drop `git_config()` wrapperPatrick Steinhardt1-2/+2
In 036876a1067 (config: hide functions using `the_repository` by default, 2024-08-13) we have moved around a bunch of functions in the config subsystem that depend on `the_repository`. Those function have been converted into mere wrappers around their equivalent function that takes in a repository as parameter, and the intent was that we'll eventually remove those wrappers to make the dependency on the global repository variable explicit at the callsite. Follow through with that intent and remove `git_config()`. All callsites are adjusted so that they use `repo_config(the_repository, ...)` instead. While some callsites might already have a repository available, this mechanical conversion is the exact same as the current situation and thus cannot cause any regression. Those sites should eventually be cleaned up in a later patch series. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2025-07-16commit: avoid scanning trailing comments when 'core.commentChar' is "auto"Ayush Chandekar1-1/+5
When core.commentChar is set to "auto", Git selects a comment character by scanning the commit message contents and avoiding any character already present in the message. If the message still contains old conflict comments (starting with a comment character), Git assumes that character is in use and chooses a different one. As a result, those existing comment lines are no longer recognized as comments and end up being included in the final commit message. To avoid this, skip scanning the trailing comment block when selecting the comment character. This allows Git to safely reuse the original character when appropriate, keeping the commit message clean and free of leftover conflict information. Background: The "auto" value for core.commentchar was introduced in the commit 84c9dc2c5a (commit: allow core.commentChar=auto for character auto selection, 2014-05-17) but did not exhibit this issue at that time. The bug was introduced in commit a6c2654f83 (rebase -m: fix --signoff with conflicts, 2024-04-18) where Git started writing conflict comments to the file at 'rebase_path_message()'.

The difference of two unsigned integers is defined to be unsigned, and therefore it is misleading to check whether it is greater than zero (instead, the more natural way would be to check whether the difference is zero or not).

2025-04-17global: use designated initializers for optionsPatrick Steinhardt1-14/+48
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.

2025-02-28path: drop `git_path()` in favor of `repo_git_path()`Patrick Steinhardt1-3/+5
Remove `git_path()` in favor of the `repo_git_path()` family of functions, which makes the implicit dependency on `the_repository` go away. Note that `git_path()` returned a string allocated via `get_pathname()`, which uses a rotating set of statically allocated buffers. Consequently, callers didn't have to free the returned string. The same isn't true for `repo_common_path()`, so we also have to add logic to free the returned strings. This refactoring also allows us to remove `repo_common_pathv()` as well as `get_pathname()` from the public interface.

2024-08-14config: fix leaking comment character configPatrick Steinhardt1-2/+5
When the comment line character has been specified multiple times in the configuration, then `git_default_core_config()` will cause a memory leak because it unconditionally copies the string into `comment_line_str` without free'ing the previous value. In fact, it can't easily free the value in the first place because it may contain a string constant. Refactor the code such that we track allocated comment character strings via a separate non-constant variable `comment_line_str_to_free`. Adapt sites that set `comment_line_str` to set both and free the old value that was stored in `comment_line_str_to_free`. This memory leak is being hit in t3404.

2024-06-11commit: fix leaking parents when calling `commit_tree_extended()`Patrick Steinhardt1-1/+2
When creating commits via `commit_tree_extended()`, the caller passes in a string list of parents. This call implicitly transfers ownership of that list to the function, which is quite surprising to begin with. But to make matters worse, `commit_tree_extended()` doesn't even bother to free the list of parents in error cases. The result is a memory leak, and one that the caller cannot fix by themselves because they do not know whether parts of the string list have already been released. Refactor the code such that callers can keep ownership of the list of parents, which is getting indicated by parameter being a constant pointer now.

Exit code is 0 in both cases (unlike without --include). This is also described in the TODO comment before the relevant testcase. Fix this by passing a character array to add_files_to_cache() to collect the pathspec matching information and error out if the given path is untracked. Also, amend the testcase to check for the error message and remove the TODO comment. Signed-off-by: Ghanshyam Thakkar <shyamthakkar001@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2024-04-03revision: optionally record matches with pathspec elementsJunio C Hamano1-1/+1
Unlike "git add" and other end-user facing commands, where it is diagnosed as an error to give a pathspec with an element that does not match any path, the diff machinery does not care if some elements of the pathspec do not match. Given that the diff machinery is heavily used in pathspec-limited "git log" machinery, and it is common for a path to come and go while traversing the project history, this is usually a good thing. However, in some cases we would want to know if all the pathspec elements matched. For example, "git add -u <pathspec>" internally uses the machinery used by "git diff-files" to decide contents from what paths to add to the index, and as an end-user facing command, "git add -u" would want to report an unmatched pathspec element. Add a new .ps_matched member next to the .prune_data member in "struct rev_info" so that we can optionally keep track of the use of .prune_data pathspec elements that can be inspected by the caller.

As part of our transition to multi-byte comment characters, let's take a NUL-terminated string pointer for strbuf_stripspace(), rather than a single character. We can continue to support its feature of ignoring comments by accepting a NULL pointer (as opposed to the current behavior of a NUL byte). All of the callers have to be adjusted, but they can all just pass comment_line_str (or NULL). Inside the function we detect comments by comparing the first byte of a line to the comment character. We'll adjust that to use starts_with(), which will match multiple bytes (though for now, of course, we still only allow a single byte, so it's academic).

2024-03-12environment: store comment_line_char as a stringJeff King1-2/+2
We'd like to eventually support multi-byte comment prefixes, but the comment_line_char variable is referenced in many spots, making the transition difficult. Let's start by storing the character in a NUL-terminated string. That will let us switch code over incrementally to the string format, and we can easily support the existing code with a macro wrapper (since we'll continue to allow only a single-byte prefix, this will behave identically). Once all references to the "char" variable have been converted, we can drop it and enable longer strings. We'll still have to touch all of the spots that create or set the variable in this patch, but there are only a few (reading the config, and the "auto" character selector).

2024-03-12commit: refactor base-case of adjust_comment_line_char()Jeff King1-2/+3
When core.commentChar is set to "auto", we check a set of candidate characters against the proposed buffer to see which if any can be used without ambiguity. But before we do that, we optimize for the common case that the default "#" is fine by just seeing if it is present in the buffer at all. The way we do this is a bit subtle, though: we assign the candidate character to comment_line_char preemptively, then check if it works, and return if it does. The subtle part is that sometimes setting comment_line_char is important (after we return, the important outcome is the fact that we have set the variable) and sometimes it is useless (if our optimization fails, we go on to do the more careful checks and eventually assign something else instead). To make it more clear what is happening (and to make further refactoring of comment_line_char easier), let's check our candidate character directly, and then assign as part of returning if it worked out.

These error messages say "new_index" as if that spelling has some significance to the end users (e.g. the file "$GIT_DIR/new_index" has some issues), but that is not the case at all.

Spell it "new index", as we are just telling the users that we failed to create a new index file.

2023-06-29commit -a -m: allow the top-level tree to become empty againJohannes Schindelin1-5/+2
In 03267e8656c (commit: discard partial cache before (re-)reading it, 2022-11-08), a memory leak was plugged by discarding any partial index before re-reading it. The problem with this memory leak fix is that it was based on an incomplete understanding of the logic introduced in 7168624c353 (Do not generate full commit log message if it is not going to be used, 2007-11-28). That logic was introduced to add a shortcut when committing without editing the commit message interactively. A part of that logic was to ensure that the index was read into memory: if (!active_nr && read_cache() < 0) die(...) Translation to English: If the index has not yet been read, read it, and if that fails, error out. That logic was incorrect, though: It used `!active_nr` as an indicator that the index was not yet read. Usually this is not a problem because in the vast majority of instances, the index contains at least one entry. And it was natural to do it this way because at the time that condition was introduced, the `index_state` structure had no explicit flag to indicate that it was initialized: This flag was only introduced in 913e0e99b6a (unpack_trees(): protect the handcrafted in-core index from read_cache(), 2008-08-23), but that commit did not adjust the code path where no index file was found and a new, pristine index was initialized. Now, when the index does not contain any entry (which is quite common in Git's test suite because it starts quite a many repositories from scratch), subsequent calls to `do_read_index()` will mistake the index not to be initialized, and read it again unnecessarily. This is a problem because after initializing the empty index e.g. the `cache_tree` in that index could have been initialized before a subsequent call to `do_read_index()` wants to ensure an initialized index. And if that subsequent call mistakes the index not to have been initialized, it would lead to leaked memory. The correct fix for that memory leak is to adjust the condition so that it does not mistake `active_nr == 0` to mean that the index has not yet been read. Using the `initialized` flag instead, we avoid that mistake, and as a bonus we can fix a bug at the same time that was introduced by the memory leak fix: When deleting all tracked files and then asking `git commit -a -m ...` to commit the result, Git would internally update the index, then discard and re-read the index undoing the update, and fail to commit anything.

2023-06-28config: pass kvi to die_bad_number()Glen Choo1-4/+6
Plumb "struct key_value_info" through all code paths that end in die_bad_number(), which lets us remove the helper functions that read analogous values from "struct config_reader". As a result, nothing reads config_reader.config_kvi any more, so remove that too. In config.c, this requires changing the signature of git_configset_get_value() to 'return' "kvi" in an out parameter so that git_configset_get_<type>() can pass it to git_config_<type>(). Only numeric types will use "kvi", so for non-numeric types (e.g. git_configset_get_string()), pass NULL to indicate that the out parameter isn't needed. Outside of config.c, config callbacks now need to pass "ctx->kvi" to any of the git_config_<type>() functions that parse a config string into a number type. Included is a .cocci patch to make that refactor. The only exceptional case is builtin/config.c, where git_config_<type>() is called outside of a config callback (namely, on user-provided input), so config source information has never been available. In this case, die_bad_number() defaults to a generic, but perfectly descriptive message. Let's provide a safe, non-NULL for "kvi" anyway, but make sure not to change the message.

2023-06-28config: add ctx arg to config_fn_tGlen Choo1-4/+6
Add a new "const struct config_context *ctx" arg to config_fn_t to hold additional information about the config iteration operation. config_context has a "struct key_value_info kvi" member that holds metadata about the config source being read (e.g. what kind of config source it is, the filename, etc). In this series, we're only interested in .kvi, so we could have just used "struct key_value_info" as an arg, but config_context makes it possible to add/adjust members in the future without changing the config_fn_t signature. We could also consider other ways of organizing the args (e.g. moving the config name and value into config_context or key_value_info), but in my experiments, the incremental benefit doesn't justify the added complexity (e.g. a config_fn_t will sometimes invoke another config_fn_t but with a different config value). In subsequent commits, the .kvi member will replace the global "struct config_reader" in config.c, making config iteration a global-free operation. It requires much more work for the machinery to provide meaningful values of .kvi, so for now, merely change the signature and call sites, pass NULL as a placeholder value, and don't rely on the arg in any meaningful way. Most of the changes are performed by contrib/coccinelle/config_fn_ctx.pending.cocci, which, for every config_fn_t: - Modifies the signature to accept "const struct config_context *ctx" - Passes "ctx" to any inner config_fn_t, if needed - Adds UNUSED attributes to "ctx", if needed Most config_fn_t instances are easily identified by seeing if they are called by the various config functions. Most of the remaining ones are manually named in the .cocci patch. Manual cleanups are still needed, but the majority of it is trivial; it's either adjusting config_fn_t that the .cocci patch didn't catch, or adding forward declarations of "struct config_context ctx" to make the signatures make sense. The non-trivial changes are in cases where we are invoking a config_fn_t outside of config machinery, and we now need to decide what value of "ctx" to pass. These cases are: - trace2/tr2_cfg.c:tr2_cfg_set_fl() This is indirectly called by git_config_set() so that the trace2 machinery can notice the new config values and update its settings using the tr2 config parsing function, i.e. tr2_cfg_cb(). - builtin/checkout.c:checkout_main() This calls git_xmerge_config() as a shorthand for parsing a CLI arg. This might be worth refactoring away in the future, since git_xmerge_config() can call git_default_config(), which can do much more than just parsing. Handle them by creating a KVI_INIT macro that initializes "struct key_value_info" to a reasonable default, and use that to construct the "ctx" arg.

I'm not sure if the other two callers would want to add a `--sparse` flag similar to add.c to get non-default behavior, but exposing this dependence will help if we ever decide we do want to add such a flag.

2023-06-16commit: pass --no-divider to interpret-trailersJeff King1-1/+2
When git-commit sees any "--trailer" options, it passes the COMMIT_EDITMSG file through git-interpret-trailers. But it does so without passing --no-divider, which means that interpret-trailers will look for a "---" divider to signal the end of the commit message. That behavior doesn't make any sense in this context; we know we have a complete and solitary commit message, not something we have to further parse. And as a result, we'll do the wrong thing if the commit message contains a "---" marker (which otherwise is not syntactically significant), inserting any new trailers at the wrong spot. We can fix this by passing --no-divider. This is the exact situation for which it was added in 1688c9a489 (interpret-trailers: allow suppressing "---" divider, 2018-08-22). As noted in the message for that commit, it just adds the mechanism, and further patches were needed to trigger it from various callers. We did that back then in a few spots, like ffce7f590f (sequencer: ignore "---" divider when parsing trailers, 2018-08-22), but obviously missed this one.

As a library that only interacts with other primitives, strbuf should not utilize the comment_line_char global variable within its functions. Therefore, add an additional parameter for functions that use comment_line_char and refactor callers to pass it in instead. strbuf_stripspace() removes the skip_comments boolean and checks if comment_line_char is a non-NUL character to determine whether to skip comments or not.

Instead of forcing the porcelain commands to always read the configuration variables related to the signing and verifying signatures, lazily initialize the necessary subsystem on demand upon the first use. This hopefully would make it more future-proof as we do not have to think and decide whether we should call git_gpg_config() in the git_config() callback for each command. A few git_config() callback functions that used to be custom callbacks are now just a thin wrapper around git_default_config(). We could further remove, git_FOO_config and replace calls to git_config(git_FOO_config) with git_config(git_default_config), but to make it clear which ones are affected and the effect is only the removal of git_gpg_config(), it is vastly preferred not to do such a change in this step (they can be done on top once the dust settled).

2022-11-21built-ins: use free() not UNLEAK() if trivial, rm dead codeÆvar Arnfjörð Bjarmason1-3/+3
For a lot of uses of UNLEAK() it would be quite tricky to release the memory involved, or we're missing the relevant *_(release|clear)() functions. But in these cases we have them already, and can just invoke them on the variable(s) involved, instead of UNLEAK(). For "builtin/worktree.c" the UNLEAK() was also added in [1], but the struct member it's unleaking was removed in [2]. The only non-"int" member of that structure is "const char *keep_locked", which comes to us via "argv" or a string literal[3]. We have good visibility via the compiler and tooling (e.g. SANITIZE=address) on bad free()-ing, but none on UNLEAK() we don't need anymore. So let's prefer releasing the memory when it's easy. For "bugreport", "worktree" and "config" we need to start using a "ret = ..." return pattern. For "builtin/bugreport.c" these UNLEAK() were added in [4], and for "builtin/config.c" in [1]. For "config" the code seen here was the only user of the "value" variable. For "ACTION_{RENAME,REMOVE}_SECTION" we need to be sure to return the right exit code in the cases where we were relying on falling through to the top-level. I think there's still a use-case for UNLEAK(), but hat it's changed since then. Using it so that "we can see the real leaks" is counter-productive in these cases. It's more useful to have UNLEAK() be a marker of the remaining odd cases where it's hard to free() the memory for whatever reason. With this change less than 20 of them remain in-tree. 1. 0e5bba53af7 (add UNLEAK annotation for reducing leak false positives, 2017-09-08) 2. d861d34a6ed (worktree: remove extra members from struct add_opts, 2018-04-24) 3. 0db4961c49b (worktree: teach `add` to accept --reason <string> with --lock, 2021-07-15) 4. 0e5bba53af7 and 00d8c311050 (commit: fix "author_ident" leak, 2022-05-12).

2022-11-21commit: discard partial cache before (re-)reading itÆvar Arnfjörð Bjarmason1-2/+5
The read_cache() in prepare_to_commit() would end up clobbering the pointer we had for a previously populated "the_index.cache_tree" in the very common case of "git commit" stressed by e.g. the tests being changed here. We'd populate "the_index.cache_tree" by calling "update_main_cache_tree" in prepare_index(), but would not end up with a "fully prepared" index. What constitutes an existing index is clearly overly fuzzy, here we'll check "active_nr" (aka "the_index.cache_nr"), but our "the_index.cache_tree" might have been malloc()'d already. Thus the code added in 11c8a74a64a (commit: write cache-tree data when writing index anyway, 2011-12-06) would end up allocating the "cache_tree", and would interact here with code added in 7168624c353 (Do not generate full commit log message if it is not going to be used, 2007-11-28).

2022-05-12commit: fix "author_ident" leakJunio C Hamano1-3/+6
Since 4c28e4ada03 (commit: die before asking to edit the log message, 2010-12-20), we have been "leaking" the "author_ident" when prepare_to_commit() fails. Instead of returning from right there, introduce an exit status variable and jump to the clean-up label at the end. Instead of explicitly releasing the resource with strbuf_release(), mark the variable with UNLEAK() at the end, together with two other variables that are already marked as such. If this were in a utility function that is called number of times, but these are different, we should explicitly release resources that grow proportionally to the size of the problem being solved, but cmd_commit() is like main() and there is no point in spending extra cycles to release individual pieces of resource at the end, just before process exit will clean everything for us for free anyway. This fixes a leak demonstrated by e.g. "t3505-cherry-pick-empty.sh", but unfortunately we cannot mark it or other affected tests as passing now with "TEST_PASSES_SANITIZE_LEAK=true" as we'll need to fix many other memory leaks before doing so. Incidentally there are two tests that always passes the leak checker with or without this change. Mark them as such. This is based on an earlier patch by Ævar, but takes a different approach that is more maintainable.

2022-04-13revisions API: have release_revisions() release "mailmap"Ævar Arnfjörð Bjarmason1-3/+2
Extend the the release_revisions() function so that it frees the "mailmap" in the "struct rev_info". The log family of functions now calls the clear_mailmap() function added in fa8afd18e5a (revisions API: provide and use a release_revisions(), 2021-09-19), allowing us to whitelist some tests with "TEST_PASSES_SANITIZE_LEAK=true". Unfortunately having a pointer to a mailmap in "struct rev_info" instead of an embedded member that we "own" get a bit messy, as can be seen in the change to builtin/commit.c. When we free() this data we won't be able to tell apart a pointer to a "mailmap" on the heap from one on the stack. As seen in ea57bc0d41b (log: add --use-mailmap option, 2013-01-05) the "log" family allocates it on the heap, but in the find_author_by_nickname() code added in ea16794e430 (commit: search author pattern against mailmap, 2013-08-23) we allocated it on the stack instead. Ideally we'd simply change that member to a "struct string_list mailmap" and never free() the "mailmap" itself, but that would be a much larger change to the revisions API. We have code that needs to hand an existing "mailmap" to a "struct rev_info", while we could change all of that, let's not go there now. The complexity isn't in the ownership of the "mailmap" per-se, but that various things assume a "rev_info.mailmap == NULL" means "doesn't want mailmap", if we changed that to an init'd "struct string_list we'd need to carefully refactor things to change those assumptions. Let's instead always free() it, and simply declare that if you add such a "mailmap" it must be allocated on the heap. Any modern libc will correctly panic if we free() a stack variable, so this should be safe going forward.

2022-03-07hooks: fix an obscure TOCTOU "did we just run a hook?" raceÆvar Arnfjörð Bjarmason1-7/+11
Fix a Time-of-check to time-of-use (TOCTOU) race in code added in 680ee550d72 (commit: skip discarding the index if there is no pre-commit hook, 2017-08-14). This obscure race condition can occur if we e.g. ran the "pre-commit" hook and it modified the index, but hook_exists() returns false later on (e.g., because the hook itself went away, the directory became unreadable, etc.). Then we won't call discard_cache() when we should have. The race condition itself probably doesn't matter, and users would have been unlikely to run into it in practice. This problem has been noted on-list when 680ee550d72 was discussed[1], but had not been fixed. This change is mainly intended to improve the readability of the code involved, and to make reasoning about it more straightforward. It wasn't as obvious what we were trying to do here, but by having an "invoked_hook" it's clearer that e.g. our discard_cache() is happening because of the earlier hook execution. Let's also change this for the push-to-checkout hook. Now instead of checking if the hook exists and either doing a push to checkout or a push to deploy we'll always attempt a push to checkout. If the hook doesn't exist we'll fall back on push to deploy. The same behavior as before, without the TOCTOU race. See 0855331941b (receive-pack: support push-to-checkout hook, 2014-12-01) for the introduction of the previous behavior. This leaves uses of hook_exists() in two places that matter. The "reference-transaction" check in refs.c, see 67541597670 (refs: implement reference transaction hook, 2020-06-19), and the "prepare-commit-msg" hook, see 66618a50f9c (sequencer: run 'prepare-commit-msg' hook, 2018-01-24). In both of those cases we're saving ourselves CPU time by not preparing data for the hook that we'll then do nothing with if we don't have the hook. So using this "invoked_hook" pattern doesn't make sense in those cases. The "reference-transaction" and "prepare-commit-msg" hook also aren't racy. In those cases we'll skip the hook runs if we race with a new hook being added, whereas in the TOCTOU races being fixed here we were incorrectly skipping the required post-hook logic. 1. https://lore.kernel.org/git/20170810191613.kpmhzg4seyxy3cpq@sigill.intra.peff.net/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Move the declaration of the date.c functions from cache.h, and adjust the relevant users to include the new date.h header. The show_ident_date() function belonged in pretty.h (it's defined in pretty.c), its two users outside of pretty.c didn't strictly need to include pretty.h, as they get it indirectly, but let's add it to them anyway. Similarly, the change to "builtin/{fast-import,show-branch,tag}.c" isn't needed as far as the compiler is concerned, but since they all use the "DATE_MODE()" macro we now define in date.h, let's have them include it. We could simply include this new header in "cache.h", but as this change shows these functions weren't common enough to warrant including in it in the first place. By moving them out of cache.h changes to this API will no longer cause a (mostly) full re-build of the project when "make" is run.

2021-07-14commit: integrate with sparse-indexDerrick Stolee1-0/+3
Update 'git commit' to allow using the sparse-index in memory without expanding to a full one. The only place that had an ensure_full_index() call was in cache_tree_update(). The recursive algorithm for update_one() was already updated in 2de37c536 (cache-tree: integrate with sparse directory entries, 2021-03-03) to handle sparse directory entries in the index. Most of this change involves testing different command-line options that allow specifying which on-disk changes should be included in the commit. This includes no options (only take currently-staged changes), -a (take all tracked changes), and --include (take a list of specific changes). To simplify testing that these options do not expand the index, update the test that previously verified that 'git status' does not expand the index with a helper method, ensure_not_expanded(). This allows 'git commit' to operate much faster when the sparse-checkout cone is much smaller than the full list of files at HEAD. Here are the relevant lines from p2000-sparse-operations.sh: Test HEAD~1 HEAD ---------------------------------------------------------------------------------- 2000.14: git commit -a -m A (full-v3) 0.35(0.26+0.06) 0.36(0.28+0.07) +2.9% 2000.15: git commit -a -m A (full-v4) 0.32(0.26+0.05) 0.34(0.28+0.06) +6.3% 2000.16: git commit -a -m A (sparse-v3) 0.63(0.59+0.06) 0.04(0.05+0.05) -93.7% 2000.17: git commit -a -m A (sparse-v4) 0.64(0.59+0.08) 0.04(0.04+0.04) -93.8% It is important to compare the full-index case to the sparse-index case, so the improvement for index version v4 is actually an 88% improvement in this synthetic example. In a real repository with over two million files at HEAD and 60,000 files in the sparse-checkout definition, the time for 'git commit -a' went from 2.61 seconds to 134ms. I compared this to the result if the index only contained the paths in the sparse-checkout definition and found the theoretical optimum to be 120ms, so the out-of-cone paths only add a 12% overhead.

2021-07-14status: use sparse-index throughoutDerrick Stolee1-0/+3
By testing 'git -c core.fsmonitor= status -uno', we can check for the simplest index operations that can be made sparse-aware. The necessary implementation details are already integrated with sparse-checkout, so modify command_requires_full_index to be zero for cmd_status(). In refresh_index(), we loop through the index entries to refresh their stat() information. However, sparse directories have no stat() information to populate. Ignore these entries. This allows 'git status' to no longer expand a sparse index to a full one. This is further tested by dropping the "-uno" option and adding an untracked file into the worktree. The performance test p2000-sparse-checkout-operations.sh demonstrates these improvements: Test HEAD~1 HEAD ----------------------------------------------------------------------------- 2000.2: git status (full-index-v3) 0.31(0.30+0.05) 0.31(0.29+0.06) +0.0% 2000.3: git status (full-index-v4) 0.31(0.29+0.07) 0.34(0.30+0.08) +9.7% 2000.4: git status (sparse-index-v3) 2.35(2.28+0.10) 0.04(0.04+0.05) -98.3% 2000.5: git status (sparse-index-v4) 2.35(2.24+0.15) 0.05(0.04+0.06) -97.9% Note that since HEAD~1 was expanding the sparse index by parsing trees, it was artificially slower than the full index case. Thus, the 98% improvement is misleading, and instead we should celebrate the 0.34s to 0.05s improvement of 85%. This is more indicative of the peformance gains we are expecting by using a sparse index. Note: we are dropping the assignment of core.fsmonitor here. This is not necessary for the test script as we are not altering the config any other way. Correct integration with FS Monitor will be validated in later changes.

2021-01-12shortlog: remove unused(?) "repo-abbrev" featureÆvar Arnfjörð Bjarmason1-1/+1
Remove support for the magical "repo-abbrev" comment in .mailmap files. This was added to .mailmap parsing in [1], as a generalized feature of the git-shortlog Perl script added earlier in [2]. There was no documentation or tests for this feature, and I don't think it's used in practice anymore. What it did was to allow you to specify a single string to be search-replaced with "/.../" in the .mailmap file. E.g. for linux.git's current .mailmap: git archive --remote=git@gitlab.com:linux-kernel/linux.git \ HEAD -- .mailmap | grep -a repo-abbrev # repo-abbrev: /pub/scm/linux/kernel/git/ Then when running e.g.: git shortlog --merges --author=Linus -1 v5.10-rc7..v5.10 | grep Merge We'd emit (the [...] is mine): Merge tag [...]git://git.kernel.org/.../tip/tip But will now emit: Merge tag [...]git.kernel.org/pub/scm/linux/kernel/git/tip/tip I think at this point this is just a historical artifact we can get rid of. It was initially meant for Linus's own use when we integrated the Perl script[2], but since then it seems he's stopped using it. Digging through Linus's release announcements on the LKML[3] the last release I can find that made use of this output is Linux 2.6.25-rc6 back in March 2008[4]. Later on Linus started using --no-merges[5], and nowadays seems to prefer some custom not-quite-shortlog format of merges from lieutenants[6]. You will still see it on linux.git if you run "git shortlog" manually yourself with --merges, with this removed you can still get the same output with: git log --pretty=fuller v5.10-rc7..v5.10 | sed 's!/pub/scm/linux/kernel/git/!/.../!g' | git shortlog Arguably we should do the same for the search-replacing of "[PATCH]" at the beginning with "". That seems to be another relic of a bygone era when linux.git patches would have their E-Mail subject lines applied as-is by "git am" or whatever. But we documented that feature in "git-shortlog(1)", and it seems more widely applicable than something purely kernel-specific. 1. 7595e2ee6ef (git-shortlog: make common repository prefix configurable with .mailmap, 2006-11-25) 2. fa375c7f1b6 (Add git-shortlog perl script, 2005-06-04) 3. https://lore.kernel.org/lkml/ 4. https://lore.kernel.org/lkml/alpine.LFD.1.00.0803161651350.3020@woody.linux-foundation.org/ 5. https://lore.kernel.org/lkml/BANLkTinrbh7Xi27an3uY7pDWrNKhJRYmEA@mail.gmail.com/ 6. https://lore.kernel.org/lkml/CAHk-=wg1+kf1AVzXA-RQX0zjM6t9J2Kay9xyuNqcFHWV-y5ZYw@mail.gmail.com/ Acked-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-10-20Documentation: stylistically normalize references to Signed-off-by:Bradley M. Kuhn1-1/+1
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.

The run_auto_gc() method is used in several places to trigger a check for repo maintenance after some Git commands, such as 'git commit' or 'git fetch'. To allow for extra customization of this maintenance activity, replace the 'git gc --auto [--quiet]' call with one to 'git maintenance run --auto [--quiet]'. As we extend the maintenance builtin with other steps, users will be able to select different maintenance activities. Rename run_auto_gc() to run_auto_maintenance() to be clearer what is happening on this call, and to expose all callers in the current diff. Rewrite the method to use a struct child_process to simplify the calls slightly. Since 'git fetch' already allows disabling the 'git gc --auto' subprocess, add an equivalent option with a different name to be more descriptive of the new behavior: '--[no-]maintenance'.

2020-08-17am: stop exporting GIT_COMMITTER_DATEPhillip Wood1-2/+2
The implementation of --committer-date-is-author-date exports GIT_COMMITTER_DATE to override the default committer date but does not reset GIT_COMMITTER_DATE in the environment after creating the commit so it is set in the environment of any hooks that get run. We're about to add the same functionality to the sequencer and do not want to have GIT_COMMITTER_DATE set when running hooks or exec commands so lets update commit_tree_extended() to take an explicit committer so we override the default date without setting GIT_COMMITTER_DATE in the environment.

2020-07-30strvec: rename struct fieldsJeff King1-1/+1
The "argc" and "argv" names made sense when the struct was argv_array, but now they're just confusing. Let's rename them to "nr" (which we use for counts elsewhere) and "v" (which is rather terse, but reads well when combined with typical variable names like "args.v"). Note that we have to update all of the callers immediately. Playing tricks with the preprocessor is hard here, because we wouldn't want to rewrite unrelated tokens.

2020-07-28strvec: convert builtin/ callers away from argv_array nameJeff King1-3/+3
We eventually want to drop the argv_array name and just use strvec consistently. There's no particular reason we have to do it all at once, or care about interactions between converted and unconverted bits. Because of our preprocessor compat layer, the names are interchangeable to the compiler (so even a definition and declaration using different names is OK). This patch converts all of the files in builtin/ to keep the diff to a manageable size. The conversion was done purely mechanically with: git ls-files '*.c' '*.h' | xargs perl -i -pe ' s/ARGV_ARRAY/STRVEC/g; s/argv_array/strvec/g; ' and then selectively staging files with "git add builtin/". We'll deal with any indentation/style fallouts separately. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-04-28Use OPT_CALLBACK and OPT_CALLBACK_FDenton Liu1-4/+4
In the codebase, there are many options which use OPTION_CALLBACK in a plain ol' struct definition. However, we have the OPT_CALLBACK and OPT_CALLBACK_F macros which are meant to abstract these plain struct definitions away. These macros are useful as they semantically signal to developers that these are just normal callback option with nothing fancy happening. Replace plain struct definitions of OPTION_CALLBACK with OPT_CALLBACK or OPT_CALLBACK_F where applicable. The heavy lifting was done using the following (disgusting) shell script: #!/bin/sh do_replacement () { tr '\n' '\r' | sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\s*0,\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK(\1,\2,\3,\4,\5,\6)/g' | sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK_F(\1,\2,\3,\4,\5,\6,\7)/g' | tr '\r' '\n' } for f in $(git ls-files \*.c) do do_replacement <"$f" >"$f.tmp" mv "$f.tmp" "$f" done The result was manually inspected and then reformatted to match the style of the surrounding code.

2020-04-16tests: write commit-graph with Bloom filtersDerrick Stolee1-3/+1
The GIT_TEST_COMMIT_GRAPH environment variable updates the commit- graph file whenever "git commit" is run, ensuring that we always have an updated commit-graph throughout the test suite. The GIT_TEST_COMMIT_GRAPH_CHANGED_PATHS environment variable was introduced to write the changed-path Bloom filters whenever "git commit-graph write" is run. However, the GIT_TEST_COMMIT_GRAPH trick doesn't launch a separate process and instead writes it directly. To expand the number of tests that have commits in the commit-graph file, add a helper method that computes the commit-graph and place that helper inside "git commit" and "git merge". In the helper method, check GIT_TEST_COMMIT_GRAPH_CHANGED_PATHS to ensure we are writing changed-path Bloom filters whenever possible.

2020-04-10merge: teach --autostash optionDenton Liu1-0/+2
In rebase, one can pass the `--autostash` option to cause the worktree to be automatically stashed before continuing with the rebase. This option is missing in merge, however. Implement the `--autostash` option and corresponding `merge.autoStash` option in merge which stashes before merging and then pops after. This option is useful when a developer has some local changes on a topic branch but they realize that their work depends on another branch. Previously, they had to run something like git fetch ... git stash push git merge FETCH_HEAD git stash pop but now, that is reduced to git fetch ... git merge --autostash FETCH_HEAD When an autostash is generated, it is automatically reapplied to the worktree only in three explicit situations: 1. An incomplete merge is commit using `git commit`. 2. A merge completes successfully. 3. A merge is aborted using `git merge --abort`. In all other situations where the merge state is removed using remove_merge_branch_state() such as aborting a merge via `git reset --hard`, the autostash is saved into the stash reflog instead keeping the worktree clean.

The transition plan anticipates that we will allow signatures using multiple algorithms in a single commit. In order to do so, we need to use a different header per algorithm so that it will be obvious over which data to compute the signature. The transition plan specifies that we should use "gpgsig-sha256", so wire up the commit code such that it can write and parse the current algorithm, and it can remove the headers for any algorithm when creating a new commit. Add tests to ensure that we write using the right header and that git fsck doesn't reject these commits.

2020-02-04commit-graph.h: store an odb in 'struct write_commit_graph_context'Taylor Blau1-1/+1
There are lots of places in 'commit-graph.h' where a function either has (or almost has) a full 'struct object_directory *', accesses '->path', and then throws away the rest of the struct. This can cause headaches when comparing the locations of object directories across alternates (e.g., in the case of deciding if two commit-graph layers can be merged). These paths are normalized with 'normalize_path_copy()' which mitigates some comparison issues, but not all [1]. Replace usage of 'char *object_dir' with 'odb->path' by storing a 'struct object_directory *' in the 'write_commit_graph_context' structure. This is an intermediate step towards getting rid of all path normalization in 'commit-graph.c'. Resolving a user-provided '--object-dir' argument now requires that we compare it to the known alternates for equality. Prior to this patch, an unknown '--object-dir' argument would silently exit with status zero. This can clearly lead to unintended behavior, such as verifying commit-graphs that aren't in a repository's own object store (or one of its alternates), or causing a typo to mask a legitimate commit-graph verification failure. Make this error non-silent by 'die()'-ing when the given '--object-dir' does not match any known alternate object store. [1]: In my testing, for example, I can get one side of the commit-graph code to fill object_dir with "./objects" and the other with just "objects".

2019-12-21commit --interactive: make it work with the built-in `add -i`Johannes Schindelin1-2/+6
The built-in `git add -i` machinery obviously has its `the_repository` structure initialized at the point where `cmd_commit()` calls it, and therefore does not look at the environment variable `GIT_INDEX_FILE`. But when being called from `commit --interactive`, it has to, because the index was already locked in that case, and we want to ask the interactive add machinery to work on the `index.lock` file instead of the `index` file. Technically, we could teach `run_add_i()`, or for that matter `run_add_p()`, to look specifically at that environment variable, but the entire idea of passing in a parameter of type `struct repository *` is to allow working on multiple repositories (and their index files) independently.

In ea9882bfc4 (commit: disable status hints when writing to COMMIT_EDITMSG, 2013-09-12) the intent was to disable status hints when writing to COMMIT_EDITMSG, because giving the hints in the "git status" like output in the commit message template are too late to be useful (they say things like "'git add' to stage", but that is only possible after aborting the current "git commit" session). But there is one case that the hints can be useful: When the current attempt to commit is rejected because no change is recorded in the index. The message is given and "git commit" errors out, so the hints can immediately be followed by the user. Teach the codepath to honor the configuration variable.

2019-12-18commit: forbid --pathspec-from-file --allAlexandr Miloslavskiy1-0/+3
I forgot this in my previous patch `--pathspec-from-file` for `git commit` [1]. When both `--pathspec-from-file` and `--all` were specified, `--all` took precedence and `--pathspec-from-file` was ignored. Before `--pathspec-from-file` was implemented, this case was prevented by this check in `parse_and_validate_options()` : die(_("paths '%s ...' with -a does not make sense"), argv[0]); It is unfortunate that these two cases are disconnected. This came as result of how the code was laid out before my patches, where `pathspec` is parsed outside of `parse_and_validate_options()`. This branch is already full of refactoring patches and I did not dare to go for another one. Fix by mirroring `die()` for `--pathspec-from-file` as well.

2019-12-06commit: give correct advice for empty commit during a rebasePhillip Wood1-5/+19
In dcb500dc16c (cherry-pick/revert: advise using --skip, 2019-07-02), `git commit` learned to suggest to run `git cherry-pick --skip` when trying to cherry-pick an empty patch. However, it was overlooked that there are more conditions than just a `git cherry-pick` when this advice is printed (which originally suggested the neutral `git reset`): the same can happen during a rebase. Let's suggest the correct command, even during a rebase. While at it, we adjust more places in `builtin/commit.c` that incorrectly assumed that the presence of a `CHERRY_PICK_HEAD` meant that surely this must be a `cherry-pick` in progress. Note: we take pains to handle the situation when a user runs a `git cherry-pick` _during_ a rebase. This is quite valid (e.g. in an `exec` line in an interactive rebase). On the other hand, it is not possible to run a rebase during a cherry-pick, meaning: if both `rebase-merge/` and `sequencer/` exist or CHERRY_PICK_HEAD and REBASE_HEAD point to the same commit , we still want to advise to use `git cherry-pick --skip`.

2019-06-21status: add status.aheadbehind settingJeff Hostetler1-1/+16
The --[no-]ahead-behind option was introduced in fd9b544a (status: add --[no-]ahead-behind to status and commit for V2 format, 2018-01-09). This is a necessary change of behavior in repos where the remote tracking branches can move very quickly ahead of the local branches. However, users need to remember to provide the command-line argument every time. Add a new "status.aheadBehind" config setting to change the default behavior of all git status formats.

2019-06-19commit-graph: create options for split filesDerrick Stolee1-1/+1
The split commit-graph feature is now fully implemented, but needs some more run-time configurability. Allow direct callers to 'git commit-graph write --split' to specify the values used in the merge strategy and the expire time. Update the documentation to specify these values.

2019-06-12commit-graph: collapse parameters into flagsDerrick Stolee1-1/+1
The write_commit_graph() and write_commit_graph_reachable() methods currently take two boolean parameters: 'append' and 'report_progress'. As we update these methods, adding more parameters this way becomes cluttered and hard to maintain. Collapse these parameters into a 'flags' parameter, and adjust the callers to provide flags as necessary.

2019-06-12commit-graph: return with errors during writeDerrick Stolee1-2/+3
The write_commit_graph() method uses die() to report failure and exit when confronted with an unexpected condition. This use of die() in a library function is incorrect and is now replaced by error() statements and an int return type. Return zero on success and a negative value on failure. Now that we use 'goto cleanup' to jump to the terminal condition on an error, we have new paths that could lead to uninitialized values. New initializers are added to correct for this. The builtins 'commit-graph', 'gc', and 'commit' call these methods, so update them to check the return value. Test that 'git commit-graph write' returns a proper error code when hitting a failure condition in write_commit_graph().

"git chery-pick" (and "revert" that shares the same runtime engine) that deals with multiple commits got confused when the final step gets stopped with a conflict and the user concluded the sequence with "git commit". Attempt to fix it by cleaning up the state files used by these commands in such a situation. * pw/clean-sequencer-state-upon-final-commit: fix cherry-pick/revert status after commit commit/reset: try to clean up sequencer state

2019-05-07doc: promote "git restore"Nguyễn Thái Ngọc Duy1-1/+1
The new command "git restore" (together with "git switch") are added to avoid the confusion of one-command-do-all "git checkout" for new users. They are also helpful to avoid ambiguous context. For these reasons, promote it everywhere possible. This includes documentation, suggestions/advice from other commands. One nice thing about git-restore is the ability to restore "everything", so it can be used in "git status" advice instead of both "git checkout" and "git reset". The three commands suggested by "git status" are add, rm and restore. "git checkout" is also removed from "git help" (i.e. it's no longer considered a commonly used command) Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2019-04-18merge: add scissors line on merge conflictDenton Liu1-5/+17
This fixes a bug where the scissors line is placed after the Conflicts: section, in the case where a merge conflict occurs and commit.cleanup = scissors. Next, if commit.cleanup = scissors is specified, don't produce a scissors line in commit if one already exists in the MERGE_MSG file.
