2011-11-30rebase -i: interrupt rebase when "commit --amend" failed during "reword"Libravatar Andrew Wong1-13/+23
"commit --amend" could fail in cases like the user empties the commit message, or pre-commit failed. When it fails, rebase should be interrupted and alert the user, rather than ignoring the error and continue on rebasing. This also gives users a way to gracefully interrupt a "reword" if they decided they actually want to do an "edit", or even "rebase --abort".

2011-10-17"rebase -i": support special-purpose editor to edit insn sheetLibravatar Peter Oberndorfer1-1/+14
The insn sheet used by "rebase -i" is designed to be easily editable by any text editor, but an editor that is specifically meant for it (but is otherwise unsuitable for editing regular text files) could be useful by allowing drag & drop reordering in a GUI environment, for example. The GIT_SEQUENCE_EDITOR environment variable and/or the sequence.editor configuration variable can be used to specify such an editor, while allowing the usual editor to be used to edit commit log messages. As usual, the environment variable takes precedence over the configuration variable. It is envisioned that other "sequencer" based tools will use the same mechanism.

2011-08-26rebase -i: clean error message for --continue after failed execLibravatar Matthieu Moy1-1/+17
After an "exec false" stops the rebase and gives the control back to the user, if changes are added to the index, "rebase --continue" fails with this message, which may technically be correct, but does not point at the real problem: .../git-rebase--interactive: line 774: .../.git/rebase-merge/author-script: No such file or directory We could try auto-amending HEAD, but this goes against the logic of .git/rebase-merge/author-script (see also the testcase 'auto-amend only edited commits after "edit"' in t3404-rebase-interactive.sh) to auto-amend something the user hasn't explicitely asked to edit. Instead of doing anything automatically, detect the situation and give a clean error message. While we're there, also clarify the error message in case '. "$author_script"' fails, which now corresponds to really weird senario where the author script exists but can't be read.

2011-06-19rebase -i -p: include non-first-parent commits in todo listLibravatar Andrew Wong1-2/+1
Consider this graph: D---E (topic, HEAD) / / A---B---C (master) \ F (topic2) and the following three commands: 1. git rebase -i -p A 2. git rebase -i -p --onto F A 3. git rebase -i -p B Currently, (1) and (2) will pick B, D, C, and E onto A and F, respectively. However, (3) will only pick D and E onto B, but not C, which is inconsistent with (1) and (2). As a result, we cannot modify C during the interactive-rebase. The current behavior also creates a bug if we do: 4. git rebase -i -p C In (4), E is never picked. And since interactive-rebase resets "HEAD" to "onto" before picking any commits, D and E are lost after the interactive-rebase. This patch fixes the inconsistency and bug by ensuring that all children of upstream are always picked. This essentially reverts the commit: d80d6bc146232d81f1bb4bc58e5d89263fd228d4 When compiling the todo list, commits reachable from "upstream" should never be skipped under any conditions. Otherwise, we lose the ability to modify them like (3), and create a bug like (4). Two of the tests contain a scenario like (3). Since the new behavior added more commits for picking, these tests need to be updated to account for the additional pick lines. A new test has also been added for (4).

2011-05-27rebase: write a reflog entry when finishingLibravatar Jeff 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.

2011-04-28git-rebase--interactive.sh: preserve-merges fails on merges created with no-ffLibravatar Andrew Wong1-1/+1
'git rebase' uses 'git merge' to preserve merges (-p). This preserves the original merge commit correctly, except when the original merge commit was created by 'git merge --no-ff'. In this case, 'git rebase' will fail to preserve the merge, because during 'git rebase', 'git merge' will simply fast-forward and skip the commit. For example: B / \ A---M / ---o---O---P---Q If we try to rebase M onto P, we lose the merge commit and this happens: A---B / ---o---O---P---Q To correct this, we simply do a "no fast-forward" on all merge commits when rebasing. Since by the time we decided to do a 'git merge' inside 'git rebase', it means there was a merge originally, so 'git merge' should always create a merge commit regardless of what the merge branches look like. This way, when rebase M onto P from the above example, we get: B / \ A---M / ---o---O---P---Q Signed-off-by: Andrew Wong <andrew.kw.w@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-02-10rebase -i: remove unnecessary state rebase-rootLibravatar Martin von Zweigbergk1-19/+0
Before calling 'git cherry-pick', interactive rebase currently checks if we are rebasing from root (if --root was passed). If we are, the '--ff' flag to 'git cherry-pick' is omitted. However, according to the documentation for 'git cherry-pick --ff', "If the current HEAD is the same as the parent of the cherry-picked commit, then a fast forward to this commit will be performed.". This should never be the case when rebasing from root, so it should not matter whether --ff is passed, so simplify the code by removing the condition.

Extract the code for writing the state to rebase-apply/ or rebase-merge/ when a rebase is initiated. This will make it easier to later make both interactive and non-interactive rebase remember the options used. Note that non-interactive rebase stores the sha1 of the original head in a file called orig-head, while interactive rebase stores it in a file called head. Change this by writing to orig-head in both cases. When reading, try to read from orig-head. If that fails, read from head instead. This protects users who upgraded git while they had an ongoing interactive rebase, while still making it possible to remove the code that reads from head at some point in the future.

The hints in the current "instruction sheet" template look like so: # Rebase 3f14246..a1d7e01 onto 3f14246 # # Commands: # p, pick = use commit # r, reword = use commit, but edit the commit message # e, edit = use commit, but stop for amending # s, squash = use commit, but meld into previous commit # f, fixup = like "squash", but discard this commit's log message # x <cmd>, exec <cmd> = Run a shell command <cmd>, and stop if it fails # # If you remove a line here THAT COMMIT WILL BE LOST. # However, if you remove everything, the rebase will be aborted. # This does not make it clear that the format of each line is <insn> <commit id> <explanatory text that will be printed> but the reader will probably infer that from the automatically generated pick examples above it. What about the "exec" instruction? By analogy, I might imagine that the format of that line is "exec <command> <explanatory text>", and the "x <cmd>" hint does not address that question (at first I read it as taking an argument <cmd> that is the name of a shell). Meanwhile, the mention of <cmd> makes the hints harder to scan as a table. So remove the <cmd> and add some words to remind the reader that "exec" runs a command named by the rest of the line. To make room, it is left to the manpage to explain that that command is run using $SHELL and that nonzero status from that command will pause the rebase. Wording from Junio.

2011-01-26rebase: use explicit "--" with checkoutLibravatar Jeff 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.

2010-08-13git-rebase--interactive.sh: rework skip_unnecessary_picksLibravatar Brandon Casey1-9/+14
Commit cd035b1c introduced the exec command to interactive rebase. In doing so, it modified the way that skip_unnecessary_picks iterates through the list of rebase commands so that it avoided collapsing multiple spaces into a single space. This is necessary for example if the argument to the exec command contains a path with multiple spaces in it. The way it did this was by reading each line of rebase commands into a single variable, and then breaking the individual components out using echo, sed, and cut. It used the individual broken-out components for decision making, and was still able to write the original line to the output file from the variable it had saved it in. But, since we only really need to look at anything other than the first element of the line when a 'pick' command is encountered, and even that is only necessary when we are still searching for "unnecessary" picks, and since newer rebase commands like 'exec' may not even require a sha1 field, let's make our read statement parse its input into a "command" variable, and a "rest" variable, and then only break out the sha1 from $rest, and call git-rev-parse, when absolutely necessary. I think this future proofs this subroutine, avoids calling git-rev-parse unnecessarily, and possibly with bogus arguments, and still accomplishes the goal of not mangling the $rest of the rebase command.

The typical usage pattern would be to run a test (or simply a compilation command) at given points in history. The shell command is ran (from the worktree root), and the rebase is stopped when the command fails, to give the user an opportunity to fix the problem before continuing with "git rebase --continue". This needs a little rework of skip_unnecessary_picks, which wasn't robust enough to deal with lines like exec >"file name with many spaces" in the todolist. The new version extracts command, sha1 and rest from each line, but outputs the line itself verbatim to avoid changing the whitespace layout.

2010-07-25git-rebase--interactive.sh: use printf instead of echo to print commit messageLibravatar Brandon Casey1-6/+6
On systems with an echo which defaults to the XSI-conformant behavior (Solaris, or others using Ksh), echo will interpret certain backslashed characters as control sequences. This can cause a problem for interactive rebase when it is used to rebase commits whose commit "subject" (the first line) contains any of these backslashed sequences. In this case, echo will substitute the control sequence for the backslashed characters and either the rebased commit message will differ from the original, or the rebase process will fail. Neither is desirable. So work around this issue by replacing the echo statements used to print out portions of the commit message, with printf. Also, add a test to test for this breakage.

2010-07-14add configuration variable for --autosquash option of interactive rebaseLibravatar Heiko Voigt1-0/+4
If you use this feature regularly you can now enable it by default. In case the user wants to override this config on the commandline --no-autosquash can be used to force disabling. Signed-off-by: Heiko Voigt <hvoigt@hvoigt.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2010-07-05rebase-i: style fixLibravatar Junio C Hamano1-5/+6
Case arms should align with "case" and "esac". Do not cat a file into a pipeline; just make the downstream command read from the file. Having a while statement as a downstream of a pipe is fine, but the loop should begin on its own line. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-06-11rebase -i: Abort cleanly if new base cannot be checked outLibravatar Ian Ward Comfort1-1/+2
Untracked content in the working tree may prevent rebase -i from checking out the new base onto which it wants to replay commits, if the new base commit includes files at those (now untracked) paths. Currently, rebase -i dies uncleanly in this situation, updating ORIG_HEAD and leaving a useless .git/rebase-merge directory, with which the user can do nothing useful except rebase --abort. Make rebase -i abort the procedure itself instead, as non-interactive rebase already does, and add a test for this behavior.
