'git checkout' and 'git worktree add' makes guesses based on a name of a remote-tracking branch, but does not give an error when such a remote-tracking branch cannot be uniquely identified, which has been corrected. * yn/worktree-ambiguous-remote-advice: worktree add: treat multiple matches with --guess-remote as an error worktree add: improve message for ambiguous remote branch name checkout: improve message for ambiguous remote branch name checkout: extract function to display advice for ambiguous remotes
2026-08-27checkout: improve message for ambiguous remote branch nameYoichi NAKAYAMA1-8/+20
When the user runs 'git checkout bar-topic' without specifying a remote, and there is no local branch named bar-topic, we try to guess which remote branch bar-topic refers to, then create a new branch named bar-topic that tracks the remote branch. If multiple remotes have a branch named bar-topic, we cannot determine a single remote. To make it easier to resolve the ambiguity, provide the names of the matching remotes for the specified branch name. To achieve that, add an optional feature to the `unique_tracking_name()` function that allows the matching remote names to be exposed to the caller.

2026-06-26refs: move parsing of "core.logAllRefUpdates" back into ref storesPatrick Steinhardt1-2/+5
In cc42c88945 (refs: extract out reflog config to generic layer, 2026-05-04) we have refactored how we parse "core.logAllRefUpdates" so that it happens in the generic layer. Unfortunately, this has worsened a preexisting issue where we may recurse when creating the reference store because of a chicken-and-egg problem between parsing the configuration and evaluating "onbranch" conditions. Prepare for a fix by essentially reverting that change so that we handle this setting in the respective backends again. The backends are already parsing other configuration anyway, so by moving the logic back in there we can ensure that all backend configuration is parsed the same way.

2026-06-07Merge branch 'ds/restore-sparse-index'Junio C Hamano1-6/+59
'git restore --staged' has been optimized to avoid unnecessarily expanding the sparse index when operating on paths within the sparse checkout definition, by handling sparse directory entries at the tree level. * ds/restore-sparse-index: restore: avoid sparse index expansion t1092: test 'git restore' with sparse index
2026-05-27restore: avoid sparse index expansionDerrick Stolee1-6/+59
Teach update_some() to handle sparse directory entries at the tree level rather than expanding the entire sparse index. When iterating a source tree during checkout/restore operations: - If a directory matches a sparse directory entry with the same OID, skip it entirely (no change needed). - If the OID differs and we are in non-overlay mode (e.g., restore --staged), update the sparse directory entry's OID in place. This is semantically correct because non-overlay mode removes paths not in the source tree anyway. - In overlay mode (e.g., checkout <tree> -- .), fall through to recursive descent so individual file entries are preserved correctly. Also switch from index_name_pos() to index_name_pos_sparse() for individual file lookups to avoid triggering ensure_full_index() when the file is already individually tracked in the index. Update the test expectation in t1092 to assert that 'restore --staged' no longer expands the sparse index.

"git checkout -m another-branch" was invented to deal with local changes to paths that are different between the current and the new branch, but it gave only one chance to resolve conflicts. The command was taught to create a stash to save the local changes. * hn/git-checkout-m-with-stash: checkout -m: autostash when switching branches checkout: rollback lock on early returns in merge_working_tree sequencer: teach autostash apply to take optional conflict marker labels sequencer: allow create_autostash to run silently stash: add --label-ours, --label-theirs, --label-base for apply
2026-04-29checkout -m: autostash when switching branchesHarald Nordgren1-92/+69
When switching branches with "git checkout -m", the attempted merge of local modifications may cause conflicts with the changes made on the other branch, which the user may not want to (or may not be able to) resolve right now. Because there is no easy way to recover from this situation, we discouraged users from using "checkout -m" unless they are certain their changes are trivial and within their ability to resolve conflicts. Teach the -m flow to create a temporary stash before switching and reapply it after. On success, the stash is silently applied and the list of locally modified paths is shown, same as a successful "git checkout" without "-m". If reapplying causes conflicts, the stash is kept and the user is told they can resolve and run "git stash drop", or run "git reset --hard" and later "git stash pop" to recover their changes.

2026-04-29checkout: rollback lock on early returns in merge_working_treeHarald Nordgren1-7/+22
merge_working_tree() acquires the index lock via repo_hold_locked_index() but several early return paths exit without calling rollback_lock_file(), leaving the lock held.

2026-03-03add-patch: split out `struct interactive_options`Patrick Steinhardt1-2/+2
The `struct add_p_opt` is reused both by our infra for "git add -p" and "git add -i". Users of `run_add_i()` for example are expected to pass `struct add_p_opt`. This is somewhat confusing and raises the question of which options apply to what part of the stack. But things are even more confusing than that: while callers are expected to pass in `struct add_p_opt`, these options ultimately get used to initialize a `struct add_i_state` that is used by both subsystems. So we are basically going full circle here. Refactor the code and split out a new `struct interactive_options` that hosts common options used by both. These options are then applied to a `struct interactive_config` that hosts common configuration. This refactoring doesn't yet fully detangle the two subsystems from one another, as we still end up calling `init_add_i_state()` in the "git add -p" subsystem. This will be fixed in a subsequent commit. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The config value `branch.autoSetupMerge` is parsed in `git_default_branch_config()` and stored in the global variable `git_branch_track`. This global variable can be overwritten by another repository when multiple Git repos run in the the same process. Move this value into `struct repo_config_values` in the_repository to retain current behaviours and move towards libifying Git. Since the variable is no longer a global variable, it has been renamed to `branch_track` in the struct `repo_config_values`.

However, the `--no-auto-advance` option does not auto advance, thereby allowing users the option to rework with files.

2026-02-09checkout: tell "parse_remote_branch" which command is calling itJunio C Hamano1-5/+24
When "git checkout <dwim>" and "git switch <dwim>" need to error out due to ambiguity of the branch name <dwim>, these two commands give an advise message with a sample command that tells the user how to disambiguate from the parse_remote_branch() function. The sample command hardcodes "git checkout", since this feature predates "git switch" by a large margin. To a user who said "git switch <dwim>" and got this message, it is confusing. Pass the "enum checkout_command", which was invented in the previous step for this exact purpose, down the call chain leading to parse_remote_branch() function to change the sample command shown to the user in this advise message. Also add a bit more test coverage for this "fail to DWIM under ambiguity" that we lack, as well as the message we produce when we fail.

The "git checkout", "git switch", and "git restore" commands share a single implementation, checkout_main(), which switches error message it gives using the usage string passed by each of these three front-ends. In order to be able to tweak behaviours of the commands based on which one we are executing, invent an enum that denotes which one of these three commands is currently executing, and pass that to checkout_main() instead. With this step, there is no externally visible behaviour change, as this enum parameter is only used to choose among the three usage strings. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2025-11-04refs: introduce wrapper struct for `each_ref_fn`Patrick Steinhardt1-4/+2
The `each_ref_fn` callback function type is used across our code base for several different functions that iterate through reference. There's a bunch of callbacks implementing this type, which makes any changes to the callback signature extremely noisy. An example of the required churn is e8207717f1 (refs: add referent to each_ref_fn, 2024-08-09): adding a single argument required us to change 48 files. It was already proposed back then [1] that we might want to introduce a wrapper structure to alleviate the pain going forward. While this of course requires the same kind of global refactoring as just introducing a new parameter, it at least allows us to more change the callback type afterwards by just extending the wrapper structure. One counterargument to this refactoring is that it makes the structure more opaque. While it is obvious which callsites need to be fixed up when we change the function type, it's not obvious anymore once we use a structure. That being said, we only have a handful of sites that actually need to populate this wrapper structure: our ref backends, "refs/iterator.c" as well as very few sites that invoke the iterator callback functions directly. Introduce this wrapper structure so that we can adapt the iterator interfaces more readily.

Sometimes code wants to die in a situation where it already has written an error message. To use the same error code as `die()` we have to use `exit(128)`, which is easy to get wrong and leaves magic numbers all over our codebase. Teach `die_message_builtin()` to not print any error when passed a `NULL` pointer as error string. Like this, such users can now call `die(NULL)` to achieve the same result without any hardcoded error codes.

As the "object-store.h" header is now equivalent to its low-level alternative we drop the latter and inline it into the former.

2025-04-15object-file: split out functions relating to object store subsystemPatrick Steinhardt1-0/+1
While we have the "object-store.h" header, most of the functionality for object stores is actually hosted in "object-file.c". This makes it hard to find relevant functions and causes us to mix up concerns. Split out functions relating to the object store subsystem into a new "object-store.c" file.

2025-03-10hash: stop depending on `the_repository` in `null_oid()`Patrick Steinhardt1-3/+3
The `null_oid()` function returns the object ID that only consists of zeroes. Naturally, this ID also depends on the hash algorithm used, as the number of zeroes is different between SHA1 and SHA256. Consequently, the function returns the hash-algorithm-specific null object ID. This is currently done by depending on `the_hash_algo`, which implicitly makes us depend on `the_repository`. Refactor the function to instead pass in the hash algorithm for which we want to retrieve the null object ID. Adapt callsites accordingly by passing in `the_repository`, thus bubbling up the dependency on that global variable by one layer. There are a couple of trivial exceptions for subsystems that already got rid of `the_repository`. These subsystems instead use the repository that is available via the calling context: - "builtin/grep.c" - "grep.c" - "refs/debug.c" There are also two non-trivial exceptions: - "diff-no-index.c": Here we know that we may not have a repository initialized at all, so we cannot rely on `the_repository`. Instead, we adapt `diff_no_index()` to get a `struct git_hash_algo` as parameter. The only caller is located in "builtin/diff.c", where we know to call `repo_set_hash_algo()` in case we're running outside of a Git repository. Consequently, it is fine to continue passing `the_repository->hash_algo` even in this case. - "builtin/ls-files.c": There is an in-flight patch series that drops `USE_THE_REPOSITORY_VARIABLE` in this file, which causes a semantic conflict because we use `null_oid()` in `show_submodule()`. The value is passed to `repo_submodule_init()`, which may use the object ID to resolve a tree-ish in the superproject from which we want to read the submodule config. As such, the object ID should refer to an object in the superproject, and consequently we need to use its hash algorithm. This means that we could in theory just not bother about this edge case at all and just use `the_repository` in "diff-no-index.c". But doing so would feel misdesigned. Remove the `USE_THE_REPOSITORY_VARIABLE` preprocessor define in "hash.c". Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2024-12-03refs: drop strbuf_ prefix from helpersJunio C Hamano1-1/+1
The helper functions (strbuf_branchname, strbuf_check_branch_ref, and strbuf_check_tag_ref) are about handling branch and tag names, and it is a non-essential fact that these functions use strbuf to hold these names. Rename them to make it clarify that these are more about "ref". Signed-off-by: Junio C Hamano <gitster@pobox.com>
2024-10-10checkout: refer to other-worktree branch, not refKristoffer Haugsbakk1-1/+1
We can only check out commits or branches, not refs in general. And the problem here is if another worktree is using the branch that we want to check out. Let’s be more direct and just talk about branches instead of refs. Also replace “be held” with “in use”. Further, “in use” is not restricted to a branch being checked out (e.g. the branch could be busy on a rebase), hence generalize to “or otherwise in use” in the option description.
