2009-01-11rebase: learn to rebase root commitLibravatar Thomas 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 stateLibravatar Jeff 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-verifyLibravatar Nanako 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.

2008-09-30rebase: Support preserving merges in non-interactive modeLibravatar Andreas Ericsson1-3/+19
As a result of implementation details, 'git rebase' could previously only preserve merges in interactive mode. That limitation was hard for users to understand and awkward to explain. This patch works around it by running the interactive rebase helper git-rebase--interactive with GIT_EDITOR set to ':' when the user passes "-p" but not "-i" to the rebase command. The effect is that the interactive rebase helper is used but the user never sees an editor. The test-case included in this patch was originally written by Stephen Habermann <stephen@exigencecorp.com>, but has been extensively modified since its creation.

"git rebase" without arguments on initial startup showed: fatal: Needed a single revision invalid upstream This patch makes it show the ordinary usage string. If .git/rebase-merge or .git/rebase-apply/rebasing exists, git-rebase will die with a message saying that a rebase is in progress and the user should try --skip/--abort/--continue. If .git/rebase-apply/applying exists, git-rebase will die with a message saying that git-am is in progress, regardless how many arguments are given. If no arguments are given and .git/rebase-apply/ exists, but neither a rebasing nor applying file is in that directory, git-rebase dies with a message saying that rebase-apply exists and no arguments were given.

Since the files generated and used during a rebase are never to be tracked, they should live in $GIT_DIR. While at it, avoid the rather meaningless term "dotest" to "rebase", and unhide ".dotest-merge". This was wished for on the mailing list, but so far unimplemented.

2008-07-14git-rebase: report checkout failureLibravatar Junio C Hamano1-3/+1
When detaching the HEAD to the base commit, the "git checkout" command could fail if, for example, upstream contains a file that would overrwrite a local, untracked file. Unconditionally discarding the standard error stream was done to squelch the progress and notices back when checkout did not have -q option, but there is no reason to keep doing it anymore. Noticed by Robert Shearman. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-07-07Teach "am" and "rebase" to mark the original position with ORIG_HEADLibravatar Junio C Hamano1-1/+1
"merge" and "reset" leave the original point in history in ORIG_HEAD, which makes it easy to go back to where you were before you inflict a major damage to your history and realize that you do not like the result at all. These days with reflog, we technically do not need to use ORIG_HEAD, but it is a handy way nevertheless. This teaches "am" and "rebase" (all forms --- the vanilla one that uses "am" as its backend, "-m" variant that cherry-picks, and "--interactive") to do the same. The original idea and a partial implementation to do this only for "rebase -m" was by Brian Gernhardt; this extends on his idea. Signed-off-by: Junio C Hamano <gitster@pobox.com>

When rebasing or stashing, chances are that you do not care about dirty submodules, since they are not updated by those actions anyway. So ignore the submodules' states. Note: the submodule states -- as committed in the superproject -- will still be stashed and rebased, it is _just_ the state of the submodule in the working tree which is ignored.

2008-03-16rebase [--onto O] A B: omit needless checkoutLibravatar Junio C Hamano1-20/+32
This teaches "git rebase [--onto O] A B" to omit an unnecessary checkout of branch B before it goes on. "git-rebase" originally was about rebasing the current branch to somewhere else, and when the extra parameter to name which branch to rebase was added, it defined the semantics to the safest but stupid "first switch to the named branch and then operate exactly the same way as if we were already on that branch". But the first thing the real part of "rebase" does is to reset the work tree and the index to the "onto" commit. Which means the "rebase that branch" form switched the work tree to the tip of the branch only to immediately switch again to another commit. This was wasteful.

2008-03-16rebase -m: do not trigger pre-commit verificationLibravatar Junio C Hamano1-1/+1
When rebasing changes that contain issues that the pre-commit hook flags as problematic, the rebase cannot be continued. However, rebase is about transplanting commits that are already made with as little distortion as possible, and pre-commit check should not interfere. Earlier, c5b09fe (Avoid update hook during git-rebase --interactive, 2007-12-19) fixed "rebase -i", but "rebase -m" shared the same issue. Signed-off-by: Junio C Hamano <gitster@pobox.com>

The new option --rebasing is used internally for rebase to tell am that it is being used for its purpose. This would leave .dotest/rebasing to help "completion" scripts tell if the ongoing operation is am or rebase. Also the option at the same time stands for --binary, -3 and -k which are always given when rebase drives am as its backend.

When you have a file called HEAD in your work tree, many commands that our scripts feed "HEAD" to would complain about the rev vs path ambiguity. A solution is to form command line more carefully by appending -- to them, which makes it clear that we mean HEAD rev not HEAD file. This patch would apply to maint.

2007-09-23Supplant the "while case ... break ;; esac" idiomLibravatar David Kastrup1-3/+2
A lot of shell scripts contained stuff starting with while case "$#" in 0) break ;; esac and similar. I consider breaking out of the condition instead of the body od the loop ugly, and the implied "true" value of the non-matching case is not really obvious to humans at first glance. It happens not to be obvious to some BSD shells, either, but that's because they are not POSIX-compliant. In most cases, this has been replaced by a straight condition using "test". "case" has the advantage of being faster than "test" on vintage shells where "test" is not a builtin. Since none of them is likely to run the git scripts, anyway, the added readability should be worth the change. A few loops have had their termination condition expressed differently.

Earlier, "git rerere" was enabled by creating the directory .git/rr-cache. That is definitely not in line with most other features, which are enabled by a config variable. So, check the config variable "rerere.enabled". If it is set to "false" explicitely, do not activate rerere, even if .git/rr-cache exists. This should help when you want to disable rerere temporarily. If "rerere.enabled" is not set at all, fall back to detection of the directory .git/rr-cache.

Don't you just hate the fact sometimes, that git-rebase just applies the patches, without any possibility to edit them, or rearrange them? With "--interactive", git-rebase now lets you edit the list of patches, so that you can reorder, edit and delete patches. Such a list will typically look like this: pick deadbee The oneline of this commit pick fa1afe1 The oneline of the next commit ... By replacing the command "pick" with the command "edit", you can amend that patch and/or its commit message, and by replacing it with "squash" you can tell rebase to fold that patch into the patch before that.

When you want to amend the commit message of 3 commits before the tip of the current branch, say 'master', A--B--C--D--E(master) it is sometimes handy to make your head detached at that commit with: $ git checkout HEAD~3 ;# check out B $ git commit --amend ;# without modifying contents... to create: .B'(HEAD) / A--B--C--D--E(master) and then rebase 'master' branch onto HEAD with this: $ git rebase HEAD master to result in: .B'-C'-D'-E(master=HEAD) / A--B--C--D--E However, the current code interprets HEAD after it switches to the branch 'master', which means the rebase will not do anything. You have to say something unwieldly like this instead: $ git rebase $(git rev-parse HEAD) master This fixes it by expanding the $onto commit name before switching to the target branch.
