"git rebase BASE BRANCH" rebased/updated the tip of BRANCH and checked it out, even when the BRANCH is checked out in a different worktree. This has been corrected. * es/do-not-let-rebase-switch-to-protected-branch: rebase: refuse to switch to branch already checked out elsewhere t3400: make test clean up after itself
2020-02-24rebase: refuse to switch to branch already checked out elsewhereEric Sunshine
The invocation "git rebase <upstream> <branch>" switches to <branch> before performing the rebase operation. However, unlike git-switch, git-checkout, and git-worktree which all refuse to switch to a branch that is already checked out in some other worktree, git-rebase switches to <branch> unconditionally. Curb this careless behavior by making git-rebase also refuse to switch to a branch checked out elsewhere.

2020-02-24t3400: make test clean up after itselfEric Sunshine
This test intentionally creates a file which causes rebase to fail, thus it is important that this file be deleted before subsequent tests are run which are not expecting such a failure. In the past, the common way to ensure cleanup (regardless of whether the test succeeded or failed) was either for the next test to perform the previous test's cleanup as its first step or to do the cleanup at global scope outside of any tests. With the introduction of 'test_when_finished', however, tests can be responsible for their own cleanup. Therefore, update this test to clean up after itself. A bit of history: This 'rm' invocation was moved from within the body of the following test to global scope by bffd750adf (rebase: improve error message when upstream argument is missing, 2010-05-31), which postdates, by about a month, introduction of 'test_when_finished' in 3bf7886705 (test-lib: Let tests specify commands to be run at end of test, 2010-05-02).

2020-02-16rebase: rename the two primary rebase backendsElijah Newren
Two related changes, with separate rationale for each: Rename the 'interactive' backend to 'merge' because: * 'interactive' as a name caused confusion; this backend has been used for many kinds of non-interactive rebases, and will probably be used in the future for more non-interactive rebases than interactive ones given that we are making it the default. * 'interactive' is not the underlying strategy; merging is. * the directory where state is stored is not called .git/rebase-interactive but .git/rebase-merge. Rename the 'am' backend to 'apply' because: * Few users are familiar with git-am as a reference point. * Related to the above, the name 'am' makes sentences in the documentation harder for users to read and comprehend (they may read it as the verb from "I am"); avoiding this difficult places a large burden on anyone writing documentation about this backend to be very careful with quoting and sentence structure and often forces annoying redundancy to try to avoid such problems. * Users stumble over pronunciation ("am" as in "I am a person not a backend" or "am" as in "the first and thirteenth letters in the alphabet in order are "A-M"); this may drive confusion when one user tries to explain to another what they are doing. * While "am" is the tool driving this backend, the tool driving git-am is git-apply, and since we are driving towards lower-level tools for the naming of the merge backend we may as well do so here too. * The directory where state is stored has never been called .git/rebase-am, it was always called .git/rebase-apply. For all the reasons listed above: * Modify the documentation to refer to the backends with the new names * Provide a brief note in the documentation connecting the new names to the old names in case users run across the old names anywhere (e.g. in old release notes or older versions of the documentation) * Change the (new) --am command line flag to --apply * Rename some enums, variables, and functions to reinforce the new backend names for us as well.

2020-02-16rebase: fix handling of restrict_revisionElijah Newren
restrict_revision in the original shell script was an excluded revision range. It is also treated that way by the am-backend. In the conversion from shell to C (see commit 6ab54d17be3f ("rebase -i: implement the logic to initialize $revisions in C", 2018-08-28)), the interactive-backend accidentally treated it as a positive revision rather than a negated one. This was missed as there were no tests in the testsuite that tested an interactive rebase with fork-point behavior.

2019-11-21t: teach test_cmp_rev to accept ! for not-equalsDenton Liu
In the case where we are using test_cmp_rev() to report not-equals, we write `! test_cmp_rev`. However, since test_cmp_rev() contains r1=$(git rev-parse --verify "$1") && r2=$(git rev-parse --verify "$2") && `! test_cmp_rev` will succeed if any of the rev-parses fail. This behavior is not desired. We want the rev-parses to _always_ be successful. Rewrite test_cmp_rev() to optionally accept "!" as the first argument to do a not-equals comparison. Rewrite `! test_cmp_rev` to `test_cmp_rev !` in all tests to take advantage of this new functionality. Also, rewrite the rev-parse logic to end with a `|| return 1` instead of &&-chaining into the rev-comparison logic. This makes it obvious to future readers that we explicitly intend on returning early if either of the rev-parses fail.

2019-09-03am: reload .gitattributes after patching itbrian m. carlson
When applying multiple patches with git am, or when rebasing using the am backend, it's possible that one of our patches has updated a gitattributes file. Currently, we cache this information, so if a file in a subsequent patch has attributes applied, the file will be written out with the attributes in place as of the time we started the rebase or am operation, not with the attributes applied by the previous patch. This problem does not occur when using the -m or -i flags to rebase. To ensure we write the correct data into the working tree, expire the cache after each patch that touches a path ending in ".gitattributes". Since we load these attributes in multiple separate files, we must expire them accordingly. Verify that both the am and rebase code paths work correctly, including the conflict marker size with am -3.

2019-08-27rebase: fast-forward --onto in more casesDenton Liu
Before, when we had the following graph, A---B---C (master) \ D (side) running 'git rebase --onto master... master side' would result in D being always rebased, no matter what. However, the desired behavior is that rebase should notice that this is fast-forwardable and do that instead. Add detection to `can_fast_forward` so that this case can be detected and a fast-forward will be performed. First of all, rewrite the function to use gotos which simplifies the logic. Next, since the options.upstream && !oidcmp(&options.upstream->object.oid, &options.onto->object.oid) conditions were removed in `cmd_rebase`, we reintroduce a substitute in `can_fast_forward`. In particular, checking the merge bases of `upstream` and `head` fixes a failing case in t3416. The abbreviated graph for t3416 is as follows: F---G topic / A---B---C---D---E master and the failing command was git rebase --onto master...topic F topic Before, Git would see that there was one merge base (C), and the merge and onto were the same so it would incorrectly return 1, indicating that we could fast-forward. This would cause the rebased graph to be 'ABCFG' when we were expecting 'ABCG'. With the additional logic, we detect that upstream and head's merge base is F. Since onto isn't F, it means we're not rebasing the full set of commits from master..topic. Since we're excluding some commits, a fast-forward cannot be performed and so we correctly return 0. Add '-f' to test cases that failed as a result of this change because they were not expecting a fast-forward so that a rebase is forced.

2019-03-20rebase: remove the rebase.useBuiltin settingÆvar Arnfjörð Bjarmason
Remove the rebase.useBuiltin setting, which was added as an escape hatch to disable the builtin version of rebase first released with Git 2.20. See [1] for the initial implementation of rebase.useBuiltin, and [2] and [3] for the documentation and corresponding GIT_TEST_REBASE_USE_BUILTIN option. Carrying the legacy version is a maintenance burden as seen in 7e097e27d3 ("legacy-rebase: backport -C<n> and --whitespace=<option> checks", 2018-11-20) and 9aea5e9286 ("rebase: fix regression in rebase.useBuiltin=false test mode", 2019-02-13). Since the built-in version has been shown to be stable enough let's remove the legacy version. As noted in [3] having use_builtin_rebase() shell out to get its config doesn't make any sense anymore, that was done for the purposes of spawning the legacy rebase without having modified any global state. Let's instead handle this case in rebase_config(). There's still a bunch of references to git-legacy-rebase in po/*.po, but those will be dealt with in time by the i18n effort. Even though this configuration variable only existed two releases let's not entirely delete the entry from the docs, but note its absence. Individual versions of git tend to be around for a while due to distro packaging timelines, so e.g. if we're "lucky" a given version like 2.21 might be installed on say OSX for half a decade. That'll mean some people probably setting this in config, and then when they later wonder if it's needed they can Google search the config option name or check it in git-config. It also allows us to refer to the docs from the warning for details. 1. 55071ea248 ("rebase: start implementing it as a builtin", 2018-08-07) 2. d8d0a546f0 ("rebase doc: document rebase.useBuiltin", 2018-11-14) 3. 62c23938fa ("tests: add a special setup where rebase.useBuiltin is off", 2018-11-14) 3. https://public-inbox.org/git/nycvar.QRO.7.76.6.1903141544110.41@tvgsbejvaqbjf.bet/ Acked-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Technically, the scripted version set ORIG_HEAD only in two spots (which really could have been one, because it called `git checkout $onto^0` to start the rebase and also if it could take a shortcut, and in both cases it called `git update-ref $orig_head`). Practically, it *implicitly* reset ORIG_HEAD whenever `git reset --hard` was called. However, what we really want is that it is set exactly once, at the beginning of the rebase. So let's do that.

2014-07-16rebase: omit patch-identical commits with --fork-pointJohn Keeping
When the `--fork-point` argument was added to `git rebase`, we changed the value of $upstream to be the fork point instead of the point from which we want to rebase. When $orig_head..$upstream is empty this does not change the behaviour, but when there are new changes in the upstream we are no longer checking if any of them are patch-identical with changes in $upstream..$orig_head. Fix this by introducing a new variable to hold the fork point and using this to restrict the range as an extra (negative) revision argument so that the set of desired revisions becomes (in fork-point mode): git rev-list --cherry-pick --right-only \ $upstream...$orig_head ^$fork_point This allows us to correctly handle the scenario where we have the following topology: C --- D --- E <- dev / B <- master@{1} / o --- B' --- C* --- D* <- master where: - B' is a fixed-up version of B that is not patch-identical with B; - C* and D* are patch-identical to C and D respectively and conflict textually if applied in the wrong order; - E depends textually on D. The correct result of `git rebase master dev` is that B is identified as the fork-point of dev and master, so that C, D, E are the commits that need to be replayed onto master; but C and D are patch-identical with C* and D* and so can be dropped, so that the end result is: o --- B' --- C* --- D* --- E <- dev If the fork-point is not identified, then picking B onto a branch containing B' results in a conflict and if the patch-identical commits are not correctly identified then picking C onto a branch containing D (or equivalently D*) results in a conflict. This change allows us to handle both of these cases, where previously we either identified the fork-point (with `--fork-point`) but not the patch-identical commits *or* (with `--no-fork-point`) identified the patch-identical commits but not the fact that master had been rewritten.

Since commit d44e712 (pull: support rebased upstream + fetch + pull --rebase, 2009-07-19), pull has actually chosen the most recent reflog entry which is an ancestor of the current branch if it can find one.

When we 'git rebase $upstream', git uses 'rev-parse --verify $current_branch' to find ORIG_HEAD. But if $current_branch is ambiguous, 'rev-parse --verify' emits a warning and returns a SHA1 anyway. When the wrong ambiguous choice is used, git-rebase fails non-gracefully: it emits a warning about failing to lock $current_branch, an error about being unable to checkout $current_branch again, and it might even decide the rebase is a fast-forward when it is not. In the 'rebase $upstream' case, we already know the unambiguous spelling of $current_branch is "HEAD". Fix git-rebase to find $orig_head unambiguously.

2012-07-25i18n: rebase: mark messages for translationJiang Xin
Mark messages in git-rebase.sh for translation. While doing this Jonathan noticed that the comma usage and sentence structure of the resolvemsg was not quite right, so correct that and its cousins in git-am.sh and t/t0201-gettext-fallbacks.sh at the same time. Some tests would start to fail with GETTEXT_POISON turned on after this update. Use test_i18ncmp and test_i18ngrep where appropriate to mark strings that should only be checked in the C locale output to avoid such issues.

2012-03-05Make git-{pull,rebase} message without tracking information friendlierCarlos Martín Nieto
The current message is too long and at too low a level for anybody to understand it if they don't know about the configuration format already. The text about setting up a remote is superfluous and doesn't help understand or recover from the error that has happened. Show the usage more prominently and explain how to set up the tracking information. If there is only one remote, that name is used instead of the generic <remote>. Also simplify the message we print on detached HEAD to remove unnecessary information which is better left for the documentation.

* jc/parse-date-raw: parse_date(): '@' prefix forces git-timestamp parse_date(): allow ancient git-timestamp
2012-02-04parse_date(): '@' prefix forces git-timestampJunio C Hamano
The only place that the issue this series addresses was observed where we read "cat-file commit" output and put it in GIT_AUTHOR_DATE in order to replay a commit with an ancient timestamp. With the previous patch alone, "git commit --date='20100917 +0900'" can be misinterpreted to mean an ancient timestamp, not September in year 2010. Guard this codepath by requring an extra '@' in front of the raw git timestamp on the parsing side. This of course needs to be compensated by updating get_author_ident_from_commit and the code for "git commit --amend" to prepend '@' to the string read from the existing commit in the GIT_AUTHOR_DATE environment variable.

2011-02-10rebase: use @{upstream} if no upstream specifiedMartin von Zweigbergk
'git rebase' without arguments is currently not supported. Make it default to 'git rebase @{upstream}'. That is also what 'git pull [--rebase]' defaults to, so it only makes sense that 'git rebase' defaults to the same thing. Defaulting to @{upstream} will make it possible to run e.g. 'git rebase -i' without arguments, which is probably a quite common use case. It also improves the scenario where you have multiple branches that rebase against a remote-tracking branch, where you currently have to choose between the extra network delay of 'git pull' or the slightly awkward keys to enter 'git rebase @{u}'. The error reporting when no upstream is configured for the current branch or when no branch is checked out is reused from git-pull.sh. A function is extracted into git-parse-remote.sh for this purpose.

2010-08-11unpack_trees: group error messages by typeMatthieu Moy
When an error is encountered, it calls add_rejected_file() which either - directly displays the error message and stops if in plumbing mode (i.e. if show_all_errors is not initialized at 1) - or stores it so that it will be displayed at the end with display_error_msgs(), Storing the files by error type permits to have a list of files for which there is the same error instead of having a serie of almost identical errors. As each bind_overlap error combines a file and an old file, a list cannot be done, therefore, theses errors are not stored but directly displayed.

2010-07-23rebase: protect against diff.renames configurationJunio C Hamano
We currently do not disable diff.renames configuration while rebase internally runs "format-patch" to feed "am -3". The end user configuration for "diff" should not affect the result produced by the higher level command that is related to "diff" only because internally it is implemented in terms of it. For that matter, I have a feeling that format-patch should not even look at diff.renames, but we seem to have been doing this for a long time so there is no easy way to fix this thinko. In any case, here is a much straightforward fix for "rebase". [jn: with test case from David] Reported-by: David D.
