The output of git branch is modified to mark branches checked out in a linked worktree with a "+" and color them in cyan (in contrast to the current branch, which will still be denoted with a "*" and colored in green) This is meant to communicate to the user that the branches that are marked or colored will behave differently from other branches if the user attempts to check them out or delete them, since branches checked out in another worktree cannot be checked out or deleted.

2019-05-07branch: make create_branch accept a merge base revLibravatar Denton Liu1-4/+10
When we ran something like $ git checkout -b test master... it would fail with the message fatal: Not a valid object name: 'master...'. This was caused by the call to `create_branch` where `start_name` is expected to be a valid rev. However, git-checkout allows the branch to be a valid _merge base_ rev (i.e. with a "...") so it was possible for an invalid rev to be passed in. Make `create_branch` accept a merge base rev so that this case does not error out. As a side-effect, teach git-branch how to handle merge base revs as well.

2019-04-21worktree: update is_bare heuristicsLibravatar Jonathan Tan1-0/+24
When "git branch -D <name>" is run, Git usually first checks if that branch is currently checked out. But this check is not performed if the Git directory of that repository is not at "<repo>/.git", which is the case if that repository is a submodule that has its Git directory stored as "super/.git/modules/<repo>", for example. This results in the branch being deleted even though it is checked out. This is because get_main_worktree() in worktree.c sets is_bare on a worktree only using the heuristic that a repo is bare if the worktree's path does not end in "/.git", and not bare otherwise. This is_bare code was introduced in 92718b7438 ("worktree: add details to the worktree struct", 2015-10-08), following a pre-core.bare heuristic. This patch does 2 things: - Teach get_main_worktree() to use is_bare_repository() instead, introduced in 7d1864ce67 ("Introduce is_bare_repository() and core.bare configuration variable", 2007-01-07) and updated in e90fdc39b6 ("Clean up work-tree handling", 2007-08-01). This solves the "git branch -D <name>" problem described above. However... - If a repository has core.bare=1 but the "git" command is being run from one of its secondary worktrees, is_bare_repository() returns false (which is fine, since there is a worktree available). However, treating the main worktree as non-bare when it is bare causes issues: for example, failure to delete a branch from a secondary worktree that is referred to by a main worktree's HEAD, even if that main worktree is bare. In order to avoid that, also check core.bare when setting is_bare. If core.bare=1, trust it, and otherwise, use is_bare_repository().

In preparation for deprecating "-l", let's make sure we're using the recommended option ourselves. This patch just mechanically converts "branch -l" to "branch --create-reflog". Note that with the exception of the actual "--create-reflog" test, we could actually remove "-l" entirely from most of these callers. That's because these days core.logallrefupdates defaults to true in a non-bare repository.

This test checks that the "-l" option creates a reflog. But in fact we'd create one even without it, since the default in a non-bare repository is to do so. Let's unset the config so we can be sure our "-l" option is kicking in. Note that we can't do this with test_config, since that would leave the variable unset after our test finishes, confusing downstream tests (the helper is not not smart enough to restore the previous value, and just always runs test_unconfig).

Support for the --set-upstream option was removed in 52668846ea (builtin/branch: stop supporting the "--set-upstream" option, 2017-08-17). The change did not completely remove the command due to an issue noted in the commit's log message. So, a test was added to ensure that a command which uses the '--set-upstream' option fails instead of silently acting as an alias for the '--set-upstream-to' option due to option parsing features. To avoid confusion, clarify that the option is disabled intentionally in the corresponding test description. The test is expected to be around as long as we intentionally fail on seeing the '--set-upstream' option which in turn we expect to do for a period of time after which we can be sure that existing users of '--set-upstream' are aware that the option is no longer supported.

2018-05-23t: make many tests depend less on the refs being filesLibravatar David Turner1-9/+9
Many tests are very focused on the file system representation of the loose and packed refs code. As there are plans to implement other ref storage systems, let's migrate these tests to a form that test the intent of the refs storage system instead of it internals. This will make clear to readers that these tests do not depend on which ref backend is used. The internals of the loose refs backend are still tested in t1400-update-ref.sh, whereas the tests changed in this patch focus on testing other aspects. This patch just takes care of many low hanging fruits. It does not try to completely solves the issue.

2017-10-07refs_resolve_ref_unsafe: handle d/f conflicts for writesLibravatar Jeff King1-0/+10
If our call to refs_read_raw_ref() fails, we check errno to see if the ref is simply missing, or if we encountered a more serious error. If it's just missing, then in "write" mode (i.e., when RESOLVE_REFS_READING is not set), this is perfectly fine. However, checking for ENOENT isn't sufficient to catch all missing-ref cases. In the filesystem backend, we may also see EISDIR when we try to resolve "a" and "a/b" exists. Likewise, we may see ENOTDIR if we try to resolve "a/b" and "a" exists. In both of those cases, we know that our resolved ref doesn't exist, but we return an error (rather than reporting the refname and returning a null sha1). This has been broken for a long time, but nobody really noticed because the next step after resolving without the READING flag is usually to lock the ref and write it. But in both of those cases, the write will fail with the same errno due to the directory/file conflict. There are two cases where we can notice this, though: 1. If we try to write "a" and there's a leftover directory already at "a", even though there is no ref "a/b". The actual write is smart enough to move the empty "a" out of the way. This is reasonably rare, if only because the writing code has to do an independent resolution before trying its write (because the actual update_ref() code handles this case fine). The notes-merge code does this, and before the fix in the prior commit t3308 erroneously expected this case to fail. 2. When resolving symbolic refs, we typically do not use the READING flag because we want to resolve even symrefs that point to unborn refs. Even if those unborn refs could not actually be written because of d/f conflicts with existing refs. You can see this by asking "git symbolic-ref" to report the target of a symref pointing past a d/f conflict. We can fix the problem by recognizing the other "missing" errnos and treating them like ENOENT. This should be safe to do even for callers who are then going to actually write the ref, because the actual writing process will fail if the d/f conflict is a real one (and t1404 checks these cases). Arguably this should be the responsibility of the files-backend to normalize all "missing ref" errors into ENOENT (since something like EISDIR may not be meaningful at all to a database backend). However other callers of refs_read_raw_ref() may actually care about the distinction; putting this into resolve_ref() is the minimal fix for now. The new tests in t1401 use git-symbolic-ref, which is the most direct way to check the resolution by itself. Interestingly we actually had a test that setup this case already, but we only used it to verify that the funny state could be overwritten, not that it could be resolved. We also add a new test in t3200, as "branch -m" was the original motivation for looking into this. What happens is this: 0. HEAD is pointing to branch "a" 1. The user asks to rename "a" to "a/b". 2. We create "a/b" and delete "a". 3. We then try to update any worktree HEADs that point to the renamed ref (including the main repo HEAD). To do that, we have to resolve each HEAD. But now our HEAD is pointing at "a", and we get EISDIR due to the loose "a/b". As a result, we think there is no HEAD, and we do not update it. It now points to the bogus "a". Interestingly this case used to work, but only accidentally. Before 31824d180d (branch: fix branch renaming not updating HEADs correctly, 2017-08-24), we'd update any HEAD which we couldn't resolve. That was wrong, but it papered over the fact that we were incorrectly failing to resolve HEAD. So while the bug demonstrated by the git-symbolic-ref is quite old, the regression to "branch -m" is recent. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-09-24branch: fix "copy" to never touch HEADLibravatar Junio C Hamano1-5/+5
When creating a new branch B by copying the branch A that happens to be the current branch, it also updates HEAD to point at the new branch. It probably was made this way because "git branch -c A B" piggybacked its implementation on "git branch -m A B", This does not match the usual expectation. If I were sitting on a blue chair, and somebody comes and repaints it to red, I would accept ending up sitting on a chair that is now red (I am also OK to stand, instead, as there no longer is my favourite blue chair). But if somebody creates a new red chair, modelling it after the blue chair I am sitting on, I do not expect to be booted off of the blue chair and ending up on sitting on the new red one. Let's fix this before it hits 'next'. Those who want to create a new branch and switch to it can do "git checkout B" after doing a "git branch -c B", and if that operation is so useful and deserves a short-hand way to do so, perhaps extend "git checkout -b B" to copy configurations while creating the new branch B.

2017-08-24branch: fix branch renaming not updating HEADs correctlyLibravatar Nguyễn Thái Ngọc Duy1-0/+13
There are two bugs that sort of work together and cause problems. Let's start with one in replace_each_worktree_head_symref. Before fa099d2322 (worktree.c: kill parse_ref() in favor of refs_resolve_ref_unsafe() - 2017-04-24), this code looks like this: if (strcmp(oldref, worktrees[i]->head_ref)) continue; set_worktree_head_symref(...); After fa099d2322, it is possible that head_ref can be NULL. However, the updated code takes the wrong exit. In the error case (NULL head_ref), we should "continue;" to the next worktree. The updated code makes us _skip_ "continue;" and update HEAD anyway. The NULL head_ref is triggered by the second bug in add_head_info (in the same commit). With the flag RESOLVE_REF_READING, resolve_ref_unsafe() will abort if it cannot resolve the target ref. For orphan checkouts, HEAD always points to an unborned branch, resolving target ref will always fail. Now we have NULL head_ref. Now we always update HEAD. Correct the logic in replace_ function so that we don't accidentally update HEAD on error. As it turns out, correcting the logic bug above breaks branch renaming completely, thanks to the second bug. "git branch -[Mm]" does two steps (on a normal checkout, no orphan!): - rename the branch on disk (e.g. refs/heads/abc to refs/heads/def) - update HEAD if it points to the branch being renamed. At the second step, since the branch pointed to by HEAD (e.g. "abc") no longer exists on disk, we run into a temporary orphan checkout situation that has been just corrected to _not_ update HEAD. But we need to update HEAD since it's not actually an orphan checkout. We need to update HEAD to move out of that orphan state. Correct add_head_info(), remove RESOLVE_REF_READING flag. With the flag gone, we should always return good "head_ref" in orphan checkouts (either temporary or permanent). With good head_ref, things start to work again.

2017-07-09reflog-walk: stop using fake parentsLibravatar Jeff King1-2/+1
The reflog-walk system works by putting a ref's tip into the pending queue, and then "traversing" the reflog by pretending that the parent of each commit is the previous reflog entry. This causes a number of user-visible oddities, as documented in t1414 (and the commit message which introduced it). We can fix all of them in one go by replacing the fake-reflog system with a much simpler one: just keeping a list of reflogs to show, and walking through them entry by entry. The implementation is fairly straight-forward, but there are a few items to note: 1. We obviously must skip calling add_parents_to_list() when we are traversing reflogs, since we do not want to walk the original parents at all. As a result, we must call try_to_simplify_commit() ourselves. There are other parts of add_parents_to_list() we skip, as well, but none of them should matter for a reflog traversal: - We do not allow UNINTERESTING commits, nor symmetric ranges (and we bail when these are used with "-g"). - Using --source makes no sense, since we aren't traversing. The reflog selector shows the same information with more detail. - Using --first-parent is still sensible, since you may want to see the first-parent diff for each entry. But since we're not traversing, we don't need to cull the parent list here. 2. Since we now just walk the reflog entries themselves, rather than starting with the ref tip, we now look at the "new" field of each entry rather than the "old" (i.e., we are showing entries, not faking parents). This removes all of the tricky logic around skipping past root commits. But note that we have no way to show an entry with the null sha1 in its "new" field (because such a commit obviously does not exist). Normally this would not happen, since we delete reflogs along with refs, but there is one special case. When we rename the currently checked out branch, we write two reflog entries into the HEAD log: one where the commit goes away, and another where it comes back. Prior to this commit, we show both entries with identical reflog messages. After this commit, we show only the "comes back" entry. See the update in t3200 which demonstrates this. Arguably either is fine, as the whole double-entry thing is a bit hacky in the first place. And until a recent fix, we truncated the traversal in such a case anyway, which was _definitely_ wrong. 3. We show individual reflogs in order, but choose which reflog to show at each stage based on which has the most recent timestamp. This interleaves the output from multiple reflogs based on date order, which is probably what you'd want with limiting like "-n 30". Note that the implementation aims for simplicity. It does a linear walk over the reflog queue for each commit it pulls, which may perform badly if you interleave an enormous number of reflogs. That seems like an unlikely use case; if we did want to handle it, we could probably keep a priority queue of reflogs, ordered by the timestamp of their current tip entry.

2017-07-05reflog-walk: skip over double-null oid due to HEAD renameLibravatar Jeff King1-0/+11
Since 39ee4c6c2f (branch: record creation of renamed branch in HEAD's log, 2017-02-20), a rename on the currently checked out branch will create two entries in the HEAD reflog: one where the branch goes away (switching to the null oid), and one where it comes back (switching away from the null oid). This confuses the reflog-walk code. When walking backwards, it first sees the null oid in the "old" field of the second entry. Thanks to the "root commit" logic added by 71abeb753f (reflog: continue walking the reflog past root commits, 2016-06-03), we keep looking for the next entry by scanning the "new" field from the previous entry. But that field is also null! We need to go just a tiny bit further, and look at its "old" field. But with the current code, we decide the reflog has nothing else to show and just give up. To the user this looks like the reflog was truncated by the rename operation, when in fact those entries are still there. This patch does the absolute minimal fix, which is to look back that one extra level and keep traversing. The resulting behavior may not be the _best_ thing to do in the long run (for example, we show both reflog entries each with the same commit id), but it's a simple way to fix the problem without risking further regressions.

2017-06-18branch: add a --copy (-c) option to go with --move (-m)Libravatar Sahil Dua1-0/+215
Add the ability to --copy a branch and its reflog and configuration, this uses the same underlying machinery as the --move (-m) option except the reflog and configuration is copied instead of being moved. This is useful for e.g. copying a topic branch to a new version, e.g. work to work-2 after submitting the work topic to the list, while preserving all the tracking info and other configuration that goes with the branch, and unlike --move keeping the other already-submitted branch around for reference. Like --move, when the source branch is the currently checked out branch the HEAD is moved to the destination branch. In the case of --move we don't really have a choice (other than remaining on a detached HEAD) and in order to keep the functionality consistent, we are doing it in similar way for --copy too. The most common usage of this feature is expected to be moving to a new topic branch which is a copy of the current one, in that case moving to the target branch is what the user wants, and doesn't unexpectedly behave differently than --move would. One outstanding caveat of this implementation is that: git checkout maint && git checkout master && git branch -c topic && git checkout - Will check out 'maint' instead of 'master'. This is because the @{-N} feature (or its -1 shorthand "-") relies on HEAD reflogs created by the checkout command, so in this case we'll checkout maint instead of master, as the user might expect. What to do about that is left to a future change.

However, this wasn't caught because we were expecting the command to fail for other reason as mentioned above.

2017-03-21ref-filter: make combining --merged & --no-merged an errorLibravatar Ævar Arnfjörð Bjarmason1-0/+4
Change the behavior of specifying --merged & --no-merged to be an error, instead of silently picking the option that was provided last. Subsequent changes of mine add a --no-contains option in addition to the existing --contains. Providing both of those isn't an error, and has actual meaning. Making its cousins have different behavior in this regard would be confusing to the user, especially since we'd be silently disregarding some of their command-line input.

"git branch --list" takes the "--abbrev" and "--no-abbrev" options to control the output of the object name in its "-v"(erbose) output, but a recent update started ignoring them; this fixes it before the breakage reaches to any released version. * kn/ref-filter-branch-list: branch: honor --abbrev/--no-abbrev in --list mode

2017-02-20branch: record creation of renamed branch in HEAD's logLibravatar Kyle Meyer1-2/+3
Renaming the current branch adds an event to the current branch's log and to HEAD's log. However, the logged entries differ. The entry in the branch's log represents the entire renaming operation (the old and new hash are identical), whereas the entry in HEAD's log represents the deletion only (the new sha1 is null). Extend replace_each_worktree_head_symref(), whose only caller is branch_rename(), to take a reflog message argument. This allows the creation of the new ref to be recorded in HEAD's log. As a result, the renaming event is represented by two entries (a deletion and a creation entry) in HEAD's log. It's a bit unfortunate that the branch's log and HEAD's log now represent the renaming event in different ways. Given that the renaming operation is not atomic, the two-entry form is a more accurate representation of the operation and is more useful for debugging purposes if a failure occurs between the deletion and creation events. It would make sense to move the branch's log to the two-entry form, but this would involve changes to how the rename is carried out and to how the update flags and reflogs are processed for deletions, so it may not be worth the effort.

2017-02-20rename_ref: replace empty message in HEAD's logLibravatar Kyle Meyer1-0/+5
When the current branch is renamed, the deletion of the old ref is recorded in HEAD's log with an empty message. Now that delete_ref() accepts a reflog message, provide a more descriptive message by passing along the log message that is given to rename_ref(). The next step will be to extend HEAD's log to also include the second part of the rename, the creation of the new branch.

2016-06-17tests: use test_i18n* functions to suppress false positivesLibravatar Vasco Almeida1-3/+3
The test functions test_i18ncmp and test_i18ngrep pretend success if run under GETTEXT_POISON. By using those functions to test output which is correctly marked as translatable, enables one to detect if the strings newly marked for translation are from plumbing output. If they are indeed from plumbing, the test would fail, and the string should be unmarked, since it is not seen by users. Thus, it is productive to not have false positives when running the test under GETTEXT_POISON. This commit replaces normal test functions by their i18n aware variants in use-cases know to be correctly marked for translation, suppressing false positives.

2016-06-13refs: don't dereference on renameLibravatar David Turner1-0/+9
When renaming refs, don't dereference either the origin or the destination before renaming. The origin does not need to be dereferenced because it is presently forbidden to rename symbolic refs. Not dereferencing the destination fixes a bug where renaming on top of a broken symref would use the pointed-to ref name for the moved reflog. Add a test for the reflog bug.

When renaming a branch, currently only the HEAD of current working tree is updated, but it must update HEADs of all working trees which point at the old branch. This is the current behavior, /path/to/wt's HEAD is not updated: % git worktree list /path/to 2c3c5f2 [master] /path/to/wt 2c3c5f2 [oldname] % git branch -m master master2 % git worktree list /path/to 2c3c5f2 [master2] /path/to/wt 2c3c5f2 [oldname] % git branch -m oldname newname % git worktree list /path/to 2c3c5f2 [master2] /path/to/wt 0000000 [oldname] This patch fixes this issue by updating all relevant worktree HEADs when renaming a branch.

2016-02-22branch: die on config error when unsetting upstreamLibravatar Patrick Steinhardt1-0/+7
When we try to unset upstream configurations we do not check return codes for the `git_config_set` functions.

2016-02-22branch: report errors in tracking branch setupLibravatar Patrick Steinhardt1-1/+8
When setting up a new tracking branch fails due to issues with the configuration file we do not report any errors to the user and pretend setting the tracking branch succeeded. Setting up the tracking branch is handled by the `install_branch_config` function. We do not want to simply die there as the function is not only invoked when explicitly setting upstream information with `git branch --set-upstream-to=`, but also by `git push --set-upstream` and `git clone`. While it is reasonable to die in the explict first case, we would lose information in the latter two cases, so we only print the error message but continue the program as usual.

Alternate refs backends might store reflogs somewhere other than .git/logs. Change most test code that directly accesses .git/logs to instead use git reflog commands. There are still a few tests which need direct access to reflogs: to check reflog permissions, to manually create reflogs from scratch, to save/restore reflogs, to check the format of raw reflog data, and to remove not just reflog contents, but the reflogs themselves. All cases which don't need direct access have been modified. Signed-off-by: David Turner <dturner@twopensource.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
