2024-04-03revision: optionally record matches with pathspec elementsJunio C Hamano
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.

2024-03-31checkout: omit "tracking" information on a detached HEADJunio C Hamano
By definition, a detached HEAD state is tentative and there is no configured "upstream" that it always wants to integrate with. But if you detach from a branch that is behind its upstream, e.g., $ git checkout -t -b main origin/main $ git checkout main $ git reset --hard HEAD^ $ git checkout --detach main you'd see "you are behind your upstream origin/main". This does not happen when you replace the last step in the above with any of these $ git checkout HEAD^0 $ git checkout --detach HEAD $ git checkout --detach origin/main Before 32669671 (checkout: introduce --detach synonym for "git checkout foo^{commit}", 2011-02-08) introduced the "--detach" option, the rule to decide if we show the tracking information used to be: If --quiet is not given, and if the given branch name is a real local branch (i.e. the one we can compute the file path under .git/, like 'refs/heads/master' or "HEAD" which stand for the name of the current branch", then give the tracking information. to exclude things like "git checkout master^0" (which was the official way to detach HEAD at the commit before that commit) and "git checkout origin/master^0" from showing tracking information, but still do show the tracking information for the current branch for "git checkout HEAD". The introduction of an explicit option "--detach" broke this subtley. The new rule should have been If --quiet is given, do not bother with tracking info. If --detach is given, do not bother with tracking info. Otherwise, if we know that the branch name given is a real local branch, or if we were given "HEAD" and "HEAD" is not detached, then attempt to show the tracking info. but it allowed "git checkout --detach master" to also show the tracking info by mistake. Let's tighten the rule to fix this. Reported-by: mirth hickford <mirth.hickford@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2024-03-14checkout: plug some leaks in git-restoreRubén Justo
In git-restore we need to free the pathspec and pathspec_from_file values from the struct checkout_opts. A simple fix could be to free them in cmd_restore, after the call to checkout_main returns, like we are doing [1][2] in the sibling function cmd_checkout. However, we can do even better. We have git-switch and git-restore, both of them spin-offs[3][4] of git-checkout. All three are implemented as thin wrappers around checkout_main. Considering this, it makes a lot of sense to do the cleanup closer to checkout_main. Move the cleanups, including the new_branch_info variable, to checkout_main. As a consequence, mark: t2070, t2071, t2072 and t6418 as leak-free.

2024-03-14checkout: fix interaction between --conflict and --mergePhillip Wood
When using "git checkout" to recreate merge conflicts or merge uncommitted changes when switching branch "--conflict" sensibly implies "--merge". Unfortunately the way this is implemented means that "git checkout --conflict=diff3 --no-merge" implies "--merge" violating the usual last-one-wins rule. Fix this by only overriding the value of opts->merge if "--conflicts" comes after "--no-merge" or "-[-no]-merge" is not given on the command line. The behavior of "git checkout --merge --no-conflict" is unchanged and will still merge on the basis that the "-[-no]-conflict" options are primarily intended to affect the conflict style and so "--no-conflict" should cancel a previous "--conflict" but not override "--merge". Of the four new tests the second one tests the behavior change introduced by this commit, the other three check that this commit does not regress the existing behavior.

2024-03-14checkout: cleanup --conflict=<style> parsingPhillip Wood
Passing an invalid conflict style name such as "--conflict=bad" gives the error message error: unknown style 'bad' given for 'merge.conflictstyle' which is unfortunate as it talks about a config setting rather than the option given on the command line. This happens because the implementation calls git_xmerge_config() to set the conflict style using the value given on the command line. Use the newly added parse_conflict_style_name() instead and pass the value down the call chain to override the config setting. This also means we can avoid setting up a struct config_context required for calling git_xmerge_config(). The option is now parsed in a callback to avoid having to store the option name. This is a change in behavior as now git checkout --conflict=bad --conflict=diff3 will error out when parsing "--conflict=bad" whereas before this change it would succeed because it would only try to parse the value of the last "--conflict" option given on the command line.

2024-02-13add-patch: classify '@' as a synonym for 'HEAD'Ghanshyam Thakkar
Currently, (restore, checkout, reset) commands correctly take '@' as a synonym for 'HEAD'. However, in patch mode different prompts/messages are given on command line due to patch mode machinery not considering '@' to be a synonym for 'HEAD' due to literal string comparison with the word 'HEAD', and therefore assigning patch_mode_($command)_nothead and triggering reverse mode (-R in diff-index). The NEEDSWORK comment suggested comparing commit objects to get around this. However, doing so would also take a non-checked out branch pointing to the same commit as HEAD, as HEAD. This would cause confusion to the user. Therefore, after parsing '@', replace it with 'HEAD' as reasonably early as possible. This also solves another problem of disparity between 'git checkout HEAD' and 'git checkout @' (latter detaches at the HEAD commit and the former does not). Trade-offs: - Some of the errors would show the revision argument as 'HEAD' when given '@'. This should be fine, as most users who probably use '@' would be aware that it is a shortcut for 'HEAD' and most probably used to use 'HEAD'. There is also relevant documentation in 'gitrevisions' manpage about '@' being the shortcut for 'HEAD'. Also, the simplicity of the solution far outweighs this cost. - Consider '@' as a shortcut for 'HEAD' even if 'refs/heads/@' exists at a different commit. Naming a branch '@' is an obvious foot-gun and many existing commands already take '@' for 'HEAD' even if 'refs/heads/@' exists at a different commit or does not exist at all (e.g. 'git log @', 'git push origin @' etc.). Therefore this is an existing assumption and should not be a problem.

2023-12-08config: handle NULL value when parsing non-boolsJeff King
When the config parser sees an "implicit" bool like: [core] someVariable it passes NULL to the config callback. Any callback code which expects a string must check for NULL. This usually happens via helpers like git_config_string(), etc, but some custom code forgets to do so and will segfault. These are all fairly vanilla cases where the solution is just the usual pattern of: if (!value) return config_error_nonbool(var); though note that in a few cases we have to split initializers like: int some_var = initializer(); into: int some_var; if (!value) return config_error_nonbool(var); some_var = initializer(); There are still some broken instances after this patch, which I'll address on their own in individual patches after this one.

The most important part of the refactoring is the separation of the guarding logic before making the call to die_if_checked_out() into the caller specific part (e.g., the logic that decides that the caller is trying to check out an existing branch) and the bypass due to the "--ignore-other-worktrees" option.

2023-06-28config: add ctx arg to config_fn_tGlen Choo
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.

2023-06-21merge-ll: rename from ll-mergeElijah Newren
A long term (but rather minor) pet-peeve of mine was the name ll-merge.[ch]. I thought it made it harder to realize what stuff was related to merging when I was working on the merge machinery and trying to improve it. Further, back in d1cbe1e6d8a ("hash-ll.h: split out of hash.h to remove dependency on repository.h", 2023-04-22), we have split the portions of hash.h that do not depend upon repository.h into a "hash-ll.h" (due to the recommendation to use "ll" for "low-level" in its name[1], but which I used as a suffix precisely because of my distaste for "ll-merge"). When we discussed adding additional "*-ll.h" files, a request was made that we use "ll" consistently as either a prefix or a suffix. Since it is already in use as both a prefix and a suffix, the only way to do so is to rename some files. Besides my distaste for the ll-merge.[ch] name, let me also note that the files ll-fsmonitor.h, ll-hash.h, ll-merge.h, ll-object-store.h, ll-read-cache.h would have essentially nothing to do with each other and make no sense to group. But giving them the common "ll-" prefix would group them. Using "-ll" as a suffix thus seems just much more logical to me. Rename ll-merge.[ch] to merge-ll.[ch] to achieve this consistency, and to ensure we get a more logical grouping of files.

2023-06-21add: modify add_files_to_cache() to avoid globalsElijah Newren
The function add_files_to_cache() is used by all three of builtin/{add, checkout, commit}.c. That suggests this is common library code, and should be moved somewhere else, like read-cache.c. However, the function and its helpers made use of two global variables that made straight code movement difficult: * the_index * include_sparse The latter was perhaps more problematic since it was only accessible in builtin/add.c but was still affecting builtin/checkout.c and builtin/commit.c without this fact being very clear from the code. 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. Modify add_files_to_cache() and its helpers to accept the necessary arguments instead of relying on globals.

2023-03-06parse-options: consistently allocate memory in fix_filename()Jeff King
When handling OPT_FILENAME(), we have to stick the "prefix" (if any) in front of the filename to make up for the fact that Git has chdir()'d to the top of the repository. We can do this with prefix_filename(), but there are a few special cases we handle ourselves. Unfortunately the memory allocation is inconsistent here; if we do make it to prefix_filename(), we'll allocate a string which the caller must free to avoid a leak. But if we hit our special cases, we'll return the string as-is, and a caller which tries to free it will crash. So there's no way to win. Let's consistently allocate, so that callers can do the right thing. There are now three cases to care about in the function (and hence a three-armed if/else): 1. we got a NULL input (and should leave it as NULL, though arguably this is the sign of a bug; let's keep the status quo for now and we can pick at that scab later) 2. we hit a special case that means we leave the name intact; we should duplicate the string. This includes our special "-" matching. Prior to this patch, it also included empty prefixes and absolute filenames. But we can observe that prefix_filename() already handles these, so we don't need to detect them. 3. everything else goes to prefix_filename() I've dropped the "const" from the "char **file" parameter to indicate that we're allocating, though in practice it's not really important. This is all being shuffled through a void pointer via opt->value before it hits code which ever looks at the string. And it's even a bit weird, because we are really taking _in_ a const string and using the same out-parameter for a non-const string. A better function signature would be: static char *fix_filename(const char *prefix, const char *file); but that would mean the caller dereferences the double-pointer (and the NULL check is currently handled inside this function). So I took the path of least-change here. Note that we have to fix several callers in this commit, too, or we'll break the leak-checking tests. These are "new" leaks in the sense that they are now triggered by the test suite, but these spots have always been leaky when Git is run in a subdirectory of the repository. I fixed all of the cases that trigger with GIT_TEST_PASSING_SANITIZE_LEAK. There may be others in scripts that have other leaks, but we can fix them later along with those other leaks (and again, you _couldn't_ fix them before this patch, so this is the necessary first step).
