2017-07-27rebase -i: also expand/collapse the SHA-1s via the rebase--helperLibravatar Johannes Schindelin1-25/+2
This is crucial to improve performance on Windows, as the speed is now mostly dominated by the SHA-1 transformation (because it spawns a new rev-parse process for *every* line, and spawning processes is pretty slow from Git for Windows' MSYS2 Bash).

2017-07-27rebase -i: do not invent onelines when expanding/collapsing SHA-1sLibravatar Johannes Schindelin1-1/+6
To avoid problems with short SHA-1s that become non-unique during the rebase, we rewrite the todo script with short/long SHA-1s before and after letting the user edit the script. Since SHA-1s are not intuitive for humans, rebase -i also provides the onelines (commit message subjects) in the script, purely for the user's convenience. It is very possible to generate a todo script via different means than rebase -i and then to let rebase -i run with it; In this case, these onelines are not required. And this is where the expand/collapse machinery has a bug: it *expects* that oneline, and failing to find one reuses the previous SHA-1 as "oneline". It was most likely an oversight, and made implementation in the (quite limiting) shell script language less convoluted. However, we are about to reimplement performance-critical parts in C (and due to spawning a git.exe process for every single line of the todo script, the expansion/collapsing of the SHA-1s *is* performance-hampering on Windows), therefore let's fix this bug to make cross-validation with the C version of that functionality possible.

2017-07-27rebase -i: remove useless indentationLibravatar Johannes Schindelin1-7/+7
The commands used to be indented, and it is nice to look at, but when we transform the SHA-1s, the indentation is removed. So let's do away with it. For the moment, at least: when we will use the upcoming rebase--helper to transform the SHA-1s, we *will* keep the indentation and can reintroduce it. Yet, to be able to validate the rebase--helper against the output of the current shell script version, we need to remove the extra indentation.

2017-07-27rebase -i: generate the script via rebase--helperLibravatar Johannes Schindelin1-21/+23
The first step of an interactive rebase is to generate the so-called "todo script", to be stored in the state directory as "git-rebase-todo" and to be edited by the user. Originally, we adjusted the output of `git log <options>` using a simple sed script. Over the course of the years, the code became more complicated. We now use shell scripting to edit the output of `git log` conditionally, depending whether to keep "empty" commits (i.e. commits that do not change any files). On platforms where shell scripting is not native, this can be a serious drag. And it opens the door for incompatibilities between platforms when it comes to shell scripting or to Unix-y commands. Let's just re-implement the todo script generation in plain C, using the revision machinery directly. This is substantially faster, improving the speed relative to the shell script version of the interactive rebase from 2x to 3x on Windows. Note that the rearrange_squash() function in git-rebase--interactive relied on the fact that we set the "format" variable to the config setting rebase.instructionFormat. Relying on a side effect like this is no good, hence we explicitly perform that assignment (possibly again) in rearrange_squash().

2017-02-09rebase -i: use the rebase--helper builtinLibravatar Johannes Schindelin1-0/+13
Now that the sequencer learned to process a "normal" interactive rebase, we use it. The original shell script is still used for "non-normal" interactive rebases, i.e. when --root or --preserve-merges was passed. Please note that the --root option (via the $squash_onto variable) needs special handling only for the very first command, hence it is still okay to use the helper upon continue/skip. Also please note that the --no-ff setting is volatile, i.e. when the interactive rebase is interrupted at any stage, there is no record of it. Therefore, we have to pass it from the shell script to the rebase--helper. Note: the test t3404 had to be adjusted because the the error messages produced by the sequencer comply with our current convention to start with a lower-case letter.

2017-01-07rebase--interactive: count squash commits above 10 correctlyLibravatar Jeff King1-1/+1
We generate the squash commit message incrementally running a sed script once for each commit. It parses "This is a combination of <N> commits" from the first line of the existing message, adds one to <N>, and uses the result as the number of our current message. Since f2d17068fd (i18n: rebase-interactive: mark comments of squash for translation, 2016-06-17), the first line may be localized, and sed uses a pretty liberal regex, looking for: /^#.*([0-9][0-9]*)/ The "[0-9][0-9]*" tries to match double digits, but it doesn't quite work. The first ".*" is greedy, so if you have: This is a combination of 10 commits. it will eat up "This is a combination of 1", leaving "0" to match the first "[0-9]" digit, and then skipping the optional match of "[0-9]*". As a result, the count resets every 10 commits, and a 15-commit squash would end up as: # This is a combination of 5 commits. # This is the 1st commit message: ... # This is the commit message #2: ... and so on .. # This is the commit message #10: ... # This is the commit message #1: ... # This is the commit message #2: ... etc, up to 5 ... We can fix this by making the ".*" less greedy. Instead of depending on ".*?" working portably, we can just limit the match to non-digit characters, which accomplishes the same thing.

2016-07-29rebase-interactive: drop early check for valid identLibravatar Jeff King1-3/+0
Since the very inception of interactive-rebase in 1b1dce4 (Teach rebase an interactive mode, 2007-06-25), there has been a preemptive check, before looking at any commits, to see whether the user has a valid name/email combination. This is convenient, because it means that we abort the operation before even beginning (rather than just complaining that we are unable to pick a particular commit). However, it does the wrong thing when the rebase does not actually need to generate any new commits (e.g., a fast-forward with no commits to pick, or one where the base stays the same, and we just pick the same commits without rewriting anything). In this case it may complain about the lack of ident, even though one would not be needed to complete the operation. This may seem like mere nit-picking, but because interactive rebase underlies the "preserve-merges" rebase, somebody who has set "pull.rebase" to "preserve" cannot make even a fast-forward pull without a valid ident, as we bail before even realizing the fast-forward nature. This commit drops the extra ident check entirely. This means we rely on individual commands that generate commit objects to complain. So we will continue to notice and prevent cases that actually do create commits, but with one important difference: we fail while actually executing the "pick" operations, and leave the rebase in a conflicted, half-done state. In some ways this is less convenient, but in some ways it is more so; the user can then manually commit or even "git rebase --continue" after setting up their ident (or providing it as a one-off on the command line).

2016-07-28rebase-interactive: trim leading whitespace from progress countLibravatar Johannes Sixt1-1/+1
Interactive rebase uses 'wc -l' to write the current patch number in a progress report. Some implementations of 'wc -l' produce spaces before the number, leading to ugly output such as Rebasing ( 3/8) Remove the spaces using a trivial arithmetic evaluation. Before 9588c52 (i18n: rebase-interactive: mark strings for translation) this was not a problem because printf was used to generate the text. Since that commit, the count is interpolated directly from a shell variable into the text, where the spaces remain. The total number of patches does not have this problem even though it is interpolated from a shell variable in the same manner, because the variable is set by an arithmetic evaluation. Later in the script, there is a virtually identical case where leading spaces are trimmed, but it uses a pattern substitution: todocount=$(git stripspace --strip-comments <"$todo" | wc -l) todocount=${todocount##* } I did not choose this idiom because it adds a line of code, and there is already an arithmetic evaluation in the vicinity of the line that is changed here.

2016-06-29rebase -i: restore autostash on abortLibravatar Patrick Steinhardt1-0/+1
When we abort an interactive rebase we do so by calling `die_abort`, which cleans up after us by removing the rebase state directory. If the user has requested to use the autostash feature, though, the state directory may also contain a reference to the autostash, which will now be deleted. Fix the issue by trying to re-apply the autostash in `die_abort`. This will also handle the case where the autostash does not apply cleanly anymore by recording it in a user-visible stash.

2016-05-31rebase -i: remove an unnecessary 'rerere' invocationLibravatar Johannes Sixt1-1/+0
Interactive rebase uses 'git cherry-pick' and 'git merge' to replay commits. Both invoke the 'rerere' machinery when they fail due to merge conflicts. Note that all code paths with these two commands also invoke the shell function die_with_patch when the commands fail. Since commit 629716d2 ("rerere: do use multiple variants") the second operation of the rerere machinery can be observed by a duplicated message "Recorded preimage for 'file'". This second operation records the same preimage as the first one and, hence, only wastes cycles. Remove the 'git rerere' invocation from die_with_patch. Shell function die_with_patch can be called after the failure of "git commit", too, which also calls into the rerere machinery, but it does so only after a successful commit to record the resolution. Therefore, it is wrong to call 'git rerere' from die_with_patch after "git commit" fails.

2016-05-14always quote shell arguments to test -z/-nLibravatar Jeff King1-2/+2
In shell code like: test -z $foo test -n $foo that does not quote its arguments, it's easy to think that it is actually looking at the contents of $foo in each case. But if $foo is empty, then "test" does not see any argument at all! The results are quite subtle. POSIX specifies that test's behavior depends on the number of arguments it sees, and if $foo is empty, it sees only one. The behavior in this case is: 1 argument: Exit true (0) if $1 is not null; otherwise, exit false. So in the "-z $foo" case, if $foo is empty, then we check that "-z" is non-null, and it returns success. Which happens to match what we expected. But for "-n $foo", if $foo is empty, we'll see that "-n" is non-null and still return success. That's the opposite of what we intended! Furthermore, if $foo contains whitespace, we'll end up with more than 2 arguments. The results in this case are generally unspecified (unless the first part of $foo happens to be a valid binary operator, in which case the results are specified but certainly not what we intended). And on top of this, even though "test -z $foo" _should_ work for the empty case, some older shells (reportedly ksh88) complain about the missing argument. So let's make sure we consistently quote our variable arguments to "test". After this patch, the results of: git grep 'test -[zn] [^"]' are empty.

2016-05-10rebase--interactive: avoid empty list in shell for-loopLibravatar Jeff King1-0/+1
The $strategy_opts variable contains a space-separated list of strategy options, each individually shell-quoted. To loop over each, we "unwrap" them by doing an eval like: eval ' for opt in '"$strategy_opts"' do ... done ' Note the quoting that means we expand $strategy_opts inline in the code to be evaluated (which is the right thing because we want the IFS-split and de-quoting). If the variable is empty, however, we ask the shell to eval the following code: for opt in do ... done without anything between "in" and "do". Most modern shells are happy to treat that like a noop, but reportedly ksh88 on AIX considers it a syntax error. So let's catch the case that the variable is empty and skip the eval altogether (since we know the loop would be a noop anyway).

If the user explicitly specified a merge strategy or strategy options, continue to use that strategy/option after "rebase --continue". Add a test of the corrected behavior. If --merge is specified or implied by -s or -X, then "strategy and "strategy_opts" are set to values from which "strategy_args" can be derived; otherwise they are set to empty strings. Either way, their values are propagated from one step of an interactive rebase to the next via state files. "do_merge", on the other hand, is *not* propagated to later steps of an interactive rebase. Therefore, making the initialization of "strategy_args" conditional on "do_merge" being set prevents later steps of an interactive rebase from setting it correctly. Luckily, we don't need the "do_merge" guard at all. If the rebase was started without --merge, then "strategy" and "strategy_opts" are both the empty string, which results in "strategy_args" also being set to the empty string, which is just what we want in that situation. So remove the "do_merge" guard and derive "strategy_args" from "strategy" and "strategy_opts" every time.

Recent update to "rebase -i" that tries to sanity check the edited insn sheet before it uses it has become too picky on Windows where CRLF left by the editor is turned into a trailing CR on the line read via the "read" built-in command. * gr/rebase-i-drop-warn: rebase-i: work around Windows CRLF line endings t3404: "rebase -i" gets broken when insn sheet uses CR/LF line endings
2015-10-28rebase-i: work around Windows CRLF line endingsLibravatar Junio C Hamano1-0/+12
Editors on Windows can and do save text files with CRLF line endings, which is the convention on the platform. We are seeing reports that the "read" command in a port of bash to the environment however does not strip the CRLF at the end, not adjusting for the same convention on the platform. This breaks the recently added sanity checks for the insn sheet fed to "rebase -i"; instead of an empty line (hence nothing in $command), the script was getting a lone CR in there. Special case a lone CR and treat it the same way as an empty line to work this around. This patch (also) passes the test with Git for Windows, where the issue was seen first.

"git rebase -i" had a minor regression recently, which stopped considering a line that begins with an indented '#' in its insn sheet not a comment, which is now fixed. * gr/rebase-i-drop-warn: rebase-i: loosen over-eager check_bad_cmd check rebase-i: explicitly accept tab as separator in commands
2015-10-05rebase-i: loosen over-eager check_bad_cmd checkLibravatar Matthieu Moy1-33/+29
804098bb (git rebase -i: add static check for commands and SHA-1, 2015-06-29) tried to check all insns before running any in the todo list, but it did so by implementing its own parser that is a lot stricter than necessary. We used to allow lines that are indented (including comment lines), and we used to allow a whitespace between the insn and the commit object name to be HT, among other things, that are flagged as an invalid line by mistake. Fix this by using the same tokenizer that is used to parse the todo list file in the new check. Whether it's a good thing to accept indented comments is debatable (other commands like "git commit" do not accept them), but we already accepted them in the past, and some people and scripts rely on this behavior. Also, a line starting with space followed by a '#' cannot have any meaning other than being a comment, hence it doesn't harm to accept them as comments.

2015-10-02rebase-i: explicitly accept tab as separator in commandsLibravatar Matthieu Moy1-2/+2
The git-rebase-todo is parsed several times with different parsers. In principle, the user input is normalized by transform_todo_ids and further parsing can be stricter. In case the user wrote pick deadbeef<TAB>commit message the parser of transform_todo_ids was considering the sha1 to be "deadbeef<TAB>commit", and was leaving the tab in the transformed sheet. In practice, this went unnoticed since the actual command interpretation was done later in do_next which did accept the tab as a separator. Make it explicit in the code of transform_todo_ids that tabs are accepted. This way, code that mimicks it will also accept tabs as separator. A similar construct appears in skip_unnecessary_picks, but this one comes after transform_todo_ids, hence reads the normalized format, so it needs not be changed.
