2018-08-06rebase: start implementing it as a builtinPratik Karki1-773/+0
This commit imitates the strategy that was used to convert the difftool to a builtin. We start by renaming the shell script `git-rebase.sh` to `git-legacy-rebase.sh` and introduce a `builtin/rebase.c` that simply executes the shell script version, unless the config setting `rebase.useBuiltin` is set to `true`. The motivation behind this is to rewrite all the functionality of the shell script version in the aforementioned `rebase.c`, one by one and be able to conveniently test new features by configuring `rebase.useBuiltin`. In the original difftool conversion, if sane_execvp() that attempts to run the legacy scripted version returned with non-negative status, the command silently exited without doing anything with success, but sane_execvp() should not return with non-negative status in the first place, so we use die() to notice such an abnormal case. We intentionally avoid reading the config directly to avoid messing up the GIT_* environment variables when we need to fall back to exec()ing the shell script. The test of builtin rebase can be done by `git -c rebase.useBuiltin=true rebase ...` Signed-off-by: Pratik Karki <predatoramigo@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-06-27Fix use of strategy options with interactive rebasesElijah Newren1-1/+1
git-rebase.sh wrote strategy options to .git/rebase/merge/strategy_opts in the following format: '--ours' '--renormalize' Note the double spaces. git-rebase--interactive uses sequencer.c to parse that file, and sequencer.c used split_cmdline() to get the individual strategy options. After splitting, sequencer.c prefixed each "option" with a double dash, so, concatenating all its options would result in: -- --ours -- --renormalize So, when it ended up calling try_merge_strategy(), that in turn would run git merge-$strategy -- --ours -- --renormalize $merge_base -- $head $remote instead of the expected/desired git merge-$strategy --ours --renormalize $merge_base -- $head $remote Remove the extra spaces so that when it goes through split_cmdline() we end up with the desired command line.

2018-06-27git-rebase: make --allow-empty-message the defaultElijah Newren1-1/+1
rebase backends currently behave differently with empty commit messages, largely as a side-effect of the different underlying commands on which they are based. am-based rebases apply commits with an empty commit message without stopping or requiring the user to specify an extra flag. (It is interesting to note that am-based rebases are the default rebase type, and no one has ever requested a --no-allow-empty-message flag to change this behavior.) merge-based and interactive-based rebases (which are ultimately based on git-commit), will currently halt on any such commits and require the user to manually specify what to do with the commit and continue. One possible rationale for the difference in behavior is that the purpose of an "am" based rebase is solely to transplant an existing history, while an "interactive" rebase is one whose purpose is to polish a series before making it publishable. Thus, stopping and asking for confirmation for a possible problem is more appropriate in the latter case. However, there are two problems with this rationale: 1) merge-based rebases are also non-interactive and there are multiple types of rebases that use the interactive machinery but are not explicitly interactive (e.g. when either --rebase-merges or --keep-empty are specified without --interactive). These rebases are also used solely to transplant an existing history, and thus also should default to --allow-empty-message. 2) this rationale only says that the user is more accepting of stopping in the case of an explicitly interactive rebase, not that stopping for this particular reason actually makes sense. Exploring whether it makes sense, requires backing up and analyzing the underlying commands... If git-commit did not error out on empty commits by default, accidental creation of commits with empty messages would be a very common occurrence (this check has caught me many times). Further, nearly all such empty commit messages would be considered an accidental error (as evidenced by a huge amount of documentation across version control systems and in various blog posts explaining how important commit messages are). A simple check for what would otherwise be a common error thus made a lot of sense, and git-commit gained an --allow-empty-message flag for special case overrides. This has made commits with empty messages very rare. There are two sources for commits with empty messages for rebase (and cherry-pick): (a) commits created in git where the user previously specified --allow-empty-message to git-commit, and (b) commits imported into git from other version control systems. In case (a), the user has already explicitly specified that there is something special about this commit that makes them not want to specify a commit message; forcing them to re-specify with every cherry-pick or rebase seems more likely to be infuriating than helpful. In case (b), the commit is highly unlikely to have been authored by the person who has imported the history and is doing the rebase or cherry-pick, and thus the user is unlikely to be the appropriate person to write a commit message for it. Stopping and expecting the user to modify the commit before proceeding thus seems counter-productive. Further, note that while empty commit messages was a common error case for git-commit to deal with, it is a rare case for rebase (or cherry-pick). The fact that it is rare raises the question of why it would be worth checking and stopping on this particular condition and not others. For example, why doesn't an interactive rebase automatically stop if the commit message's first line is 2000 columns long, or is missing a blank line after the first line, or has every line indented with five spaces, or any number of other myriad problems? Finally, note that if a user doing an interactive rebase does have the necessary knowledge to add a message for any such commit and wants to do so, it is rather simple for them to change the appropriate line from 'pick' to 'reword'. The fact that the subject is empty in the todo list that the user edits should even serve as a way to notify them. As far as I can tell, the fact that merge-based and interactive-based rebases stop on commits with empty commit messages is solely a by-product of having been based on git-commit. It went without notice for a long time precisely because such cases are rare. The rareness of this situation made it difficult to reason about, so when folks did eventually notice this behavior, they assumed it was there for a good reason and just added an --allow-empty-message flag. In my opinion, stopping on such messages not desirable in any of these cases, even the (explicitly) interactive case.

2018-06-27git-rebase: error out when incompatible options passedElijah Newren1-0/+35
git rebase has three different types: am, merge, and interactive, all of which are implemented in terms of separate scripts. am builds on git-am, merge builds on git-merge-recursive, and interactive builds on git-cherry-pick. We make use of features in those lower-level commands in the different rebase types, but those features don't exist in all of the lower level commands so we have a range of incompatibilities. Previously, we just accepted nearly any argument and silently ignored whichever ones weren't implemented for the type of rebase specified. Change this so the incompatibilities are documented, included in the testsuite, and tested for at runtime with an appropriate error message shown. Some exceptions I left out: * --merge and --interactive are technically incompatible since they are supposed to run different underlying scripts, but with a few small changes, --interactive can do everything that --merge can. In fact, I'll shortly be sending another patch to remove git-rebase--merge and reimplement it on top of git-rebase--interactive. * One could argue that --interactive and --quiet are incompatible since --interactive doesn't implement a --quiet mode (perhaps since cherry-pick itself does not implement one). However, the interactive mode is more quiet than the other modes in general with progress messages, so one could argue that it's already quiet.

2018-06-01rebase: use the new git-rebase--preserve-merges.shAlban Gruin1-7/+25
Create a new type of rebase, "preserve-merges", used when rebase is called with -p. Before that, the type for preserve-merges was "interactive", and some places of this script compared $type to "interactive". Instead, the code now checks if $interactive_rebase is empty or not, as it is set to "explicit" when calling an interactive rebase (and, possibly, one of its submodes), and "implied" when calling one of its submodes (eg. preserve-merges) *without* interactive rebase. It also detects the presence of the directory "$merge_dir"/rewritten left by the preserve-merges script when calling rebase --continue, --skip, etc., and, if it exists, sets the rebase mode to preserve-merges. In this case, interactive_rebase is set to "explicit", as "implied" would break some tests. Signed-off-by: Alban Gruin <alban.gruin@gmail.com>
2018-04-26rebase -i: introduce --rebase-merges=[no-]rebase-cousinsJohannes Schindelin1-1/+11
When running `git rebase --rebase-merges` non-interactively with an ancestor of HEAD as <upstream> (or leaving the todo list unmodified), we would ideally recreate the exact same commits as before the rebase. However, if there are commits in the commit range <upstream>.. that do not have <upstream> as direct ancestor (i.e. if `git log <upstream>..` would show commits that are omitted by `git log --ancestry-path <upstream>..`), this is currently not the case: we would turn them into commits that have <upstream> as direct ancestor. Let's illustrate that with a diagram: C / \ A - B - E - F \ / D Currently, after running `git rebase -i --rebase-merges B`, the new branch structure would be (pay particular attention to the commit `D`): --- C' -- / \ A - B ------ E' - F' \ / D' This is not really preserving the branch topology from before! The reason is that the commit `D` does not have `B` as ancestor, and therefore it gets rebased onto `B`. This is unintuitive behavior. Even worse, when recreating branch structure, most use cases would appear to want cousins *not* to be rebased onto the new base commit. For example, Git for Windows (the heaviest user of the Git garden shears, which served as the blueprint for --rebase-merges) frequently merges branches from `next` early, and these branches certainly do *not* want to be rebased. In the example above, the desired outcome would look like this: --- C' -- / \ A - B ------ E' - F' \ / -- D' -- Let's introduce the term "cousins" for such commits ("D" in the example), and let's not rebase them by default. For hypothetical use cases where cousins *do* need to be rebased, `git rebase --rebase=merges=rebase-cousins` needs to be used.

2018-04-26rebase: introduce the --rebase-merges optionJohannes Schindelin1-0/+6
Once upon a time, this here developer thought: wouldn't it be nice if, say, Git for Windows' patches on top of core Git could be represented as a thicket of branches, and be rebased on top of core Git in order to maintain a cherry-pick'able set of patch series? The original attempt to answer this was: git rebase --preserve-merges. However, that experiment was never intended as an interactive option, and it only piggy-backed on git rebase --interactive because that command's implementation looked already very, very familiar: it was designed by the same person who designed --preserve-merges: yours truly. Some time later, some other developer (I am looking at you, Andreas! ;-)) decided that it would be a good idea to allow --preserve-merges to be combined with --interactive (with caveats!) and the Git maintainer (well, the interim Git maintainer during Junio's absence, that is) agreed, and that is when the glamor of the --preserve-merges design started to fall apart rather quickly and unglamorously. The reason? In --preserve-merges mode, the parents of a merge commit (or for that matter, of *any* commit) were not stated explicitly, but were *implied* by the commit name passed to the `pick` command. This made it impossible, for example, to reorder commits. Not to mention to move commits between branches or, deity forbid, to split topic branches into two. Alas, these shortcomings also prevented that mode (whose original purpose was to serve Git for Windows' needs, with the additional hope that it may be useful to others, too) from serving Git for Windows' needs. Five years later, when it became really untenable to have one unwieldy, big hodge-podge patch series of partly related, partly unrelated patches in Git for Windows that was rebased onto core Git's tags from time to time (earning the undeserved wrath of the developer of the ill-fated git-remote-hg series that first obsoleted Git for Windows' competing approach, only to be abandoned without maintainer later) was really untenable, the "Git garden shears" were born [*1*/*2*]: a script, piggy-backing on top of the interactive rebase, that would first determine the branch topology of the patches to be rebased, create a pseudo todo list for further editing, transform the result into a real todo list (making heavy use of the `exec` command to "implement" the missing todo list commands) and finally recreate the patch series on top of the new base commit. That was in 2013. And it took about three weeks to come up with the design and implement it as an out-of-tree script. Needless to say, the implementation needed quite a few years to stabilize, all the while the design itself proved itself sound. With this patch, the goodness of the Git garden shears comes to `git rebase -i` itself. Passing the `--rebase-merges` option will generate a todo list that can be understood readily, and where it is obvious how to reorder commits. New branches can be introduced by inserting `label` commands and calling `merge <label>`. And once this mode will have become stable and universally accepted, we can deprecate the design mistake that was `--preserve-merges`.

rebase --merge accepts --keep-empty but just ignores it, by using an implicit interactive rebase the user still gets the rename detection of a merge based rebase but with with --keep-empty support. If rebase --keep-empty without --interactive or --merge stops for the user to resolve merge conflicts then 'git rebase --continue' will fail. This is because it uses a different code path that does not create $git_dir/rebase-apply. As rebase --keep-empty was implemented using cherry-pick it has never supported the am options and now that interactive rebases support --signoff there is no loss of functionality by using an implicit interactive rebase.

2018-03-23rebase: update invocation of rebase dot-sourced scriptsWink Saville1-0/+1
Due to historical reasons, the backend scriptlets for "git rebase" are structured a bit unusually. As originally designed, dot-sourcing them from "git rebase" was sufficient to invoke the specific backend. However, it was later discovered that some shell implementations (e.g. FreeBSD 9.x) misbehaved by continuing to execute statements following a top-level "return" rather than returning control to the next statement in "git rebase" after dot-sourcing the scriptlet. To work around this shortcoming, the whole body of git-rebase--$backend.sh was made into a shell function git_rebase__$backend, and then the very last line of the scriptlet called that function. A more normal architecture is for a dot-sourced scriptlet merely to define functions (thus acting as a function library), and for those functions to be called by the script doing the dot-sourcing. Migrate to this arrangement by moving the git_rebase__$backend call from the end of a scriptlet into "git rebase" itself. While at it, remove the large comment block from each scriptlet explaining this historic anomaly since it serves no purpose under the new normalized architecture in which a scriptlet is merely a function library.

The git UI can be improved by addressing the error messages to those they help: inexperienced and casual git users. To this intent, it is helpful to make sure the terms used in those messages can be understood by this segment of users, and that they guide them to resolve the problem. In particular, failure to apply a patch during a git rebase is a common problem that can be very destabilizing for the inexperienced user. It is important to lead them toward the resolution of the conflict (which is a 3-steps process, thus complex) and reassure them that they can escape a situation they can't handle with "--abort".

2016-12-11rebase: add --quit to cleanup rebase, leave everything else untouchedNguyễn Thái Ngọc Duy1-1/+5
There are occasions when you decide to abort an in-progress rebase and move on to do something else but you forget to do "git rebase --abort" first. Or the rebase has been in progress for so long you forgot about it. By the time you realize that (e.g. by starting another rebase) it's already too late to retrace your steps. The solution is normally rm -r .git/<some rebase dir> and continue with your life. But there could be two different directories for <some rebase dir> (and it obviously requires some knowledge of how rebase works), and the ".git" part could be much longer if you are not at top-dir, or in a linked worktree. And "rm -r" is very dangerous to do in .git, a mistake in there could destroy object database or other important data. Provide "git rebase --quit" for this use case, mimicking a precedent that is "git cherry-pick --quit".

2016-06-17i18n: git-sh-setup.sh: mark strings for translationVasco Almeida1-1/+0
Positional arguments, such as $0, $1, etc, need to be stored on shell variables for use in translatable strings, according to gettext manual [1]. Add git-sh-setup.sh to LOCALIZED_SH variable in Makefile to enable extraction of string marked for translation by xgettext. Source git-sh-i18n in git-sh-setup.sh for gettext support. git-sh-setup.sh is a shell library to be sourced by other shell scripts. In order to avoid other scripts from sourcing git-sh-i18n twice, remove line that sources it from them. Not sourcing git-sh-i18n in any script that uses gettext would lead to failure due to, for instance, gettextln not being found.

2016-05-13Merge branch 'jc/commit-tree-ignore-commit-gpgsign'Junio C Hamano1-1/+4
"git commit-tree" plumbing command required the user to always sign its result when the user sets the commit.gpgsign configuration variable, which was an ancient mistake. Rework "git rebase" that relied on this mistake so that it reads commit.gpgsign and pass (or not pass) the -S option to "git commit-tree" to keep the end-user expectation the same, while teaching "git commit-tree" to ignore the configuration variable. This will stop requiring the users to sign commit objects used internally as an implementation detail of "git stash". * jc/commit-tree-ignore-commit-gpgsign: commit-tree: do not pay attention to commit.gpgsign
2016-05-03commit-tree: do not pay attention to commit.gpgsignJunio C Hamano1-1/+4
ba3c69a9 (commit: teach --gpg-sign option, 2011-10-05) introduced a "signed commit" by teaching the --[no]-gpg-sign option and the commit.gpgsign configuration variable to various commands that create commits. Teaching these to "git commit" and "git merge", both of which are end-user facing Porcelain commands, was perfectly fine. Allowing the plumbing "git commit-tree" to suddenly change the behaviour to surprise the scripts by paying attention to commit.gpgsign was not. Among the in-tree scripts, filter-branch, quiltimport, rebase and stash are the commands that run "commit-tree". If any of these wants to allow users to always sign every single commit, they should offer their own configuration (e.g. "filterBranch.gpgsign") with an option to disable signing (e.g. "git filter-branch --no-gpgsign"). Ignoring commit.gpgsign option _obviously_ breaks the backward compatibility, but it is easy to follow the standard pattern in scripts to honor whatever configuration variable they choose to follow. E.g. case $(git config --bool commit.gpgsign) in true) sign=-S ;; *) sign= ;; esac && git commit-tree $sign ...whatever other args... Do so to make sure that "git rebase" keeps paying attention to the configuration variable, which unfortunately is a documented mistake.

2016-01-13rebase: ignore failures from "gc --auto"Jeff King1-1/+1
After rebasing, we call "gc --auto" to clean up if we created a lot of loose objects. However, we do so inside an &&-chain. If "gc --auto" fails (e.g., because a previous background gc blocked us by leaving "gc.log" in place), then: 1. We will fail to clean up the state directory, leaving the user stuck in the rebase forever (even "git am --abort" doesn't work, because it calls "gc --auto"!). 2. In some cases, we may return a bogus exit code from rebase, indicating failure when everything except the auto-gc succeeded. We can fix this by ignoring the exit code of "gc --auto".

2015-04-28rebase: silence "git checkout" for noop rebaseJeff King1-1/+1
When the branch to be rebased is already up to date, we "git checkout" the branch, print an "up to date" message, and end the rebase early. However, our checkout may print "Switched to branch 'foo'" or "Already on 'foo'", even if the user has asked for "--quiet". We should avoid printing these messages at all, "--quiet" or no. Since the rebase is a noop, this checkout can be seen as optimizing out these other two checkout operations (that happen in a real rebase): 1. Moving to the detached HEAD to start the rebase; we always feed "-q" to checkout there, and instead rely on our own custom message (which respects --quiet). 2. Finishing a rebase, where we move to the final branch. Here we actually use update-ref rather than git-checkout, and produce no messages.

2014-07-16rebase: omit patch-identical commits with --fork-pointJohn Keeping1-3/+4
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.

When a user invokes $ git rebase -i @~3 with dirty files and rebase.autostash turned on, and exits the $EDITOR with an empty buffer, the autostash fails to apply. Although the primary focus of rr/rebase-autostash was to get the git-rebase--backend.sh scripts to return control to git-rebase.sh, it missed this case in git-rebase--interactive.sh.

2014-04-23git-rebase.sh: use the $( ... ) construct for command substitutionElia Pinto1-4/+4
The Git CodingGuidelines prefer the $(...) construct for command substitution instead of using the backquotes `...`. The backquoted form is the traditional method for command substitution, and is supported by POSIX. However, all but the simplest uses become complicated quickly. In particular, embedded command substitutions and/or the use of double quotes require careful escaping with the backslash character.

Commit 15a147e (rebase: use @{upstream} if no upstream specified, 2011-02-09) says: 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. but that isn't actually the case. 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. Add a '--fork-point' argument to git-rebase that can be used to trigger this behaviour.

2013-05-29rebase: implement --[no-]autostash and rebase.autostashRamkumar Ramachandra1-3/+42
This new feature allows a rebase to be executed on a dirty worktree or index. It works by creating a temporary "dangling merge commit" out of the worktree and index changes (via 'git stash create'), and automatically applying it after a successful rebase or abort. rebase stores the SHA-1 hex of the temporary merge commit, along with the rest of the rebase state, in either .git/{rebase-merge,rebase-apply}/autostash depending on the kind of rebase. Since $state_dir is automatically removed at the end of a successful rebase or abort, so is the autostash. The advantage of this approach is that we do not affect the normal stash's reflogs, making the autostash invisible to the end-user. This means that you can use 'git stash' during a rebase as usual. When the autostash application results in a conflict, we push $state_dir/autostash onto the normal stash and remove $state_dir ending the rebase. The user can inspect the stash, and pop or drop at any time. Most significantly, this feature means that a caller like pull (with pull.rebase set to true) can easily be patched to remove the require_clean_work_tree restriction.

2013-05-12rebase: prepare to do generic housekeepingRamkumar Ramachandra1-0/+7
On successful completion of a rebase in git-rebase--$backend.sh, the $backend script cleans up on its own and exits. The cleanup routine is however, independent of the $backend, and each $backend script unnecessarily duplicates this work: rm -rf "$state_dir" git gc --auto Prepare git-rebase.sh for later patches that return control from each $backend script back to us, for performing this generic cleanup routine. The code that this patch adds is currently unreachable, and will only start to be used when git-rebase--$backend.sh scripts are taught to return control in later patches. Another advantage is that git-rebase.sh can implement a generic finish_rebase() to possibly do additional tasks in addition to the cleanup.

* ph/rebase-original: rebase: find orig_head unambiguously
2013-04-23rebase: find orig_head unambiguouslyPhil Hord1-1/+1
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. Add a test in t3400-rebase.sh which creates an ambiguous branch name and rebases it implicitly with 'git rebase $other'.

2011-10-13pull,rebase: handle GIT_WORK_TREE betterJeff King1-1/+1
You can't currently run git-pull or git-rebase from outside of the work tree, even with GIT_WORK_TREE set, due to an overeager require_work_tree function. Commit e2eb527 documents this problem and provides the infrastructure for a fix, but left it to later commits to audit and update individual scripts. Changing these scripts to use require_work_tree_exists is easy to verify. We immediately call cd_to_toplevel, anyway. Therefore no matter which function we use, the state afterwards is one of: 1. We have a work tree, and we are at the top level. 2. We don't have a work tree, and we have died. The only catch is that we must also make sure no code that ran before the cd_to_toplevel assumed that we were already in the working tree. In this case, we will only have included shell libraries and called set_reflog_action, neither of which care about the current working directory at all.

The "restore" can be misinterpreted to imply that the original branch was somehow in a broken state during the rebase operation.

2011-05-27rebase: write a reflog entry when finishingJeff King1-1/+3
When we finish a rebase, our detached HEAD is at the final result. We update the original branch ref with this result, and then point the HEAD symbolic ref at the updated branch. We write a reflog for the branch update, but not for the update of HEAD. Because we're already at the final result on the detached HEAD, moving to the branch actually doesn't change our commit sha1 at all. So in that sense, a reflog entry would be pointless. However, humans do read reflogs, and an entry saying "rebase finished: returning to refs/heads/master" can be helpful in understanding what is going on.

'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.

git-rebase--interactive.sh will soon be sourced from git-rebase.sh. Align the names of variables used in these scripts to prepare for that. Some names in git-rebase--interactive.sh, such as "author_script" and "amend", are currently used in their upper case form to refer to a file and in their lower case form to refer to something else. In these cases, change the name of the existing lower case variable and downcase the name of the variable that refers to the file. Currently, git-rebase.sh uses mostly lower case variable names, while git-rebase--interactive.sh uses mostly upper case variable names. For consistency, downcase all variables, not just the ones that will be shared between the two script files.

The sub commands '--continue', '--skip' or '--abort' may only be used standalone according to the documentation. Other options following the sub command are currently not accepted, but options preceeding them are. For example, 'git rebase --continue -v' is not accepted, while 'git rebase -v --continue' is. Tighten up the check and allow no other options when one of these sub commands are used. Only check that it is standalone for non-interactive rebase for now. Once the command line processing for interactive rebase has been replaced by the command line processing in git-rebase.sh, this check will also apply to interactive rebase.

2011-02-10rebase: improve detection of rebase in progressMartin von Zweigbergk1-39/+41
Detect early on if a rebase is in progress and what type of rebase it is (interactive, merge-based or am-based). This prepares for further refactoring where am-based rebase will be dispatched to git-rebase--am.sh and merge-based rebase will be dispatched to git-rebase--merge.sh. The idea is to use the same variables whether the type of rebase was detected from rebase-apply/ or rebase-merge/ directories or from the command line options. This will make the code more readable and will later also make it easier to dispatch to the type-specific scripts. Also show a consistent error message independent of the type of rebase that was in progress and remove the obsolete wording about being in the middle of a 'patch application', since that (an existing "$GIT_DIR"/rebase-apply/applying) aborts 'git rebase' at an earlier stage.

2011-02-10rebase: refactor reading of stateMartin von Zweigbergk1-30/+23
The code reading the state saved in $merge_dir or $rebase_dir is currently spread out in many places, making it harder to read and to introduce additional state. Extract this code into one method that reads the state. Only extract the code associated with the state that is written when the rebase is initiated. Leave the state that changes for each commmit, at least for now. Currently, when resuming a merge-based rebase using --continue or --skip, move_to_original_branch (via finish_rb_merge) will be called without head_name and orig_head set. These variables are then lazily read in move_to_original_branch if head_name is not set (together with onto, which is unnecessarily read again). Change this by always eagerly reading the state, for both am-based and merge-based rebase, in the --continue and --skip cases. Note that this does not change the behavior for am-based rebase, which read the state eagerly even before this commit. Reading the state eagerly means that part of the state will sometimes be read unnecessarily. One example is when the rebase is continued, but stops again at another merge conflict. Another example is when the rebase is aborted. However, since both of these cases involve user interaction, the delay is hopefully not noticeable. The call_merge/continue_merge loop is not affected.

2011-01-26rebase: use explicit "--" with checkoutJeff King1-1/+1
In the case of a ref/pathname conflict, checkout will already do the right thing and checkout the ref. However, for a non-existant ref, this has two advantages: 1. If a file with that pathname exists, rebase will refresh the file from the index and then rebase the current branch instead of producing an error. 2. If no such file exists, the error message using an explicit "--" is better: # before $ git rebase -i origin bogus error: pathspec 'bogus' did not match any file(s) known to git. Could not checkout bogus # after $ git rebase -i origin bogus fatal: invalid reference: bogus Could not checkout bogus The problems seem to be trigger-able only through "git rebase -i", as regular git-rebase checks the validity of the branch parameter as a ref very early on.

For git-rebase.sh, --no-ff is a synonym for --force-rebase. For git-rebase--interactive.sh, --no-ff cherry-picks all the commits in the rebased branch, instead of fast-forwarding over any unchanged commits. --no-ff offers an alternative way to deal with reverted merges. Instead of "reverting the revert" you can use "rebase --no-ff" to recreate the branch with entirely new commits (they're new because at the very least the committer time is different). This obviates the need to revert the reversion, as you can re-merge the new topic branch directly.

If the user has exported the GREP_OPTIONS environment variable, the output from "grep" and "egrep" in scripted Porcelains may be different from what they expect. For example, we may want to count number of matching lines, by "grep" piped to "wc -l", and GREP_OPTIONS=-C3 will break such use. The approach taken by this change to address this issue is to protect only our own use of grep/egrep. Because we do not unset it at the beginning of our scripts, hook scripts run from the scripted Porcelains are exposed to the same insanity this environment variable causes when grep/egrep is used to implement logic (e.g. "grep | wc -l"), and it is entirely up to the hook scripts to protect themselves. On the other hand, applypatch-msg hook may want to show offending words in the proposed commit log message using grep to the end user, and the user might want to set GREP_OPTIONS=--color to paint the match more visibly. The approach to protect only our own use without unsetting the environment variable globally will allow this use case. Signed-off-by: Junio C Hamano <gitster@pobox.com>

git-am and git-rebase are talkative scripts. Teach them to be quiet when told, allowing them to speak only when they fail or experience errors.

Drop a handful of >&2 redirection; the rest of the program sends all the info messages to stdout, not to stderr.

2009-03-02git-rebase: Add --stat and --no-stat for producing diffstat on rebaseTor Arne Vestbø1-7/+18
The behavior of --verbose is unchanged, but uses a different state variable internally, so that the meaning of verbose output may be expanded without affecting the diffstat. This is also reflected in the documentation. The configuration option rebase.stat works the same was as merg.stat, but the default is currently false.

It does not make sense to provide multiple upstream branches to either git pull --rebase, or to git rebase, so disallow both. Signed-off-by: Jay Soffian <jaysoffian@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-02-13Teach rebase to rebase even if upstream is up to dateSverre Rabbelier1-5/+19
Normally, if the current branch is up to date, the rebase is aborted. However, it may be desirable to allow rebasing even if the current branch is up to date. When using the '--whitespace=fix' option -f is implied. Signed-off-by: Sverre Rabbelier <srabbelier@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-01-11rebase: learn to rebase root commitThomas Rast1-16/+40
Teach git-rebase a new option --root, which instructs it to rebase the entire history leading up to <branch>. This option must be used with --onto <newbase>, and causes commits that already exist in <newbase> to be skipped. (Normal operation skips commits that already exist in <upstream> instead.) One possible use-case is with git-svn: suppose you start hacking (perhaps offline) on a new project, but later notice you want to commit this work to SVN. You will have to rebase the entire history, including the root commit, on a (possibly empty) commit coming from git-svn, to establish a history connection. This previously had to be done by cherry-picking the root commit manually. Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-12-10rebase: improve error messages about dirty stateJeff King1-3/+6
If you have unstaged changes in your working tree and try to rebase, you will get the cryptic "foo: needs update" message, but nothing else. If you have staged changes, you get "your index is not up-to-date". Let's improve this situation in two ways: - for unstaged changes, let's also tell them we are canceling the rebase, and why (in addition to the "needs update" lines) - for the staged changes case, let's use language that is a little more clear to the user: their index contains uncommitted changes Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-10-06rebase --no-verifyNanako Shiraishi1-1/+6
It is sometimes desirable to disable the safety net of pre-rebase hook when the user knows what he is doing (for example, when the original changes on the branch have not been shown to the public yet). This teaches --no-verify option to git-rebase, which is similar to the way pre-commit hook is bypassed by git-commit. Signed-off-by: Nanako Shiraishi <nanako3@lavabit.com> Signed-off-by: Shawn O.
