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).

2016-03-16Merge branch 'jc/sane-grep'Libravatar Junio C Hamano1-1/+2
Recent versions of GNU grep is pickier than before to decide if a file is "binary" and refuse to give line-oriented hits when we expect it to, unless explicitly told with "-a" option. As our scripted Porcelains use sane_grep wrapper for line-oriented data, even when the line may contain non-ASCII payload we took from end-user data, use "grep -a" to implement sane_grep wrapper when using an implementation of "grep" that takes the "-a" option. * jc/sane-grep: rebase-i: clarify "is this commit relevant?" test sane_grep: pass "-a" if grep accepts it
2016-03-10rebase-i: clarify "is this commit relevant?" testLibravatar Junio C Hamano1-1/+2
While I was checking all the call sites of sane_grep and sane_egrep, I noticed this one is somewhat strangely written. The lines in the file sane_grep works on all begin with 40-hex object name, so there is no real risk of confusing "test $(...) = ''" by finding something that begins with a dash, but using the status from sane_grep makes it a lot clearer what is going on.

2015-12-11rebase -i: remember merge options beyond continue actionsLibravatar Fabian Ruch1-11/+7
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.

In case of error, print the error, stop git rebase and prompt the user to fix with 'git rebase --edit-todo' or to abort. This allows to avoid doing half of a rebase before finding an error and giving back what's left of the todo list to the user and prompt him to fix when it might be too late for him to do so (he might have to abort and restart the rebase).

Check if commits were removed (i.e. a line was deleted) and print warnings or stop git rebase depending on the value of the configuration variable rebase.missingCommitsCheck. This patch gives the user the possibility to avoid silent loss of information (losing a commit through deleting the line in this case) if he wants. Add the configuration variable rebase.missingCommitsCheck. - When unset or set to "ignore", no checking is done. - When set to "warn", the commits are checked, warnings are displayed but git rebase still proceeds. - When set to "error", the commits are checked, warnings are displayed and the rebase is stopped. (The user can then use 'git rebase --edit-todo' and 'git rebase --continue', or 'git rebase --abort') rebase.missingCommitsCheck defaults to "ignore".

2015-05-22rebase -i: fix post-rewrite hook with failed exec commandLibravatar Matthieu Moy1-5/+5
Usually, when 'git rebase' stops before completing the rebase, it is to give the user an opportunity to edit a commit (e.g. with the 'edit' command). In such cases, 'git rebase' leaves the sha1 of the commit being rewritten in "$state_dir"/stopped-sha, and subsequent 'git rebase --continue' will call the post-rewrite hook with this sha1 as <old-sha1> argument to the post-rewrite hook. The case of 'git rebase' stopping because of a failed 'exec' command is different: it gives the opportunity to the user to examine or fix the failure, but does not stop saying "here's a commit to edit, use --continue when you're done". So, there's no reason to call the post-rewrite hook for 'exec' commands. If the user did rewrite the commit, it would be with 'git commit --amend' which already called the post-rewrite hook. Fix the behavior to leave no stopped-sha file in case of failed exec command, and teach 'git rebase --continue' to skip record_in_rewritten if no stopped-sha file is found.

2015-04-29rebase -i: redo tasks that die during cherry-pickLibravatar Phil Hord1-0/+16
When rebase--interactive processes a task, it removes the item from the todo list and appends it to another list of executed tasks. If a pick (this includes squash and fixup) fails before the index has recorded the changes, take the corresponding item and put it on the todo list again. Otherwise, the changes introduced by the scheduled commit would be lost. That kind of decision is possible since the cherry-pick command signals why it failed to apply the changes of the given commit. Either the changes are recorded in the index using a conflict (return value 1) and rebase does not continue until they are resolved or the changes are not recorded in the index (return value neither 0 nor 1) and rebase has to try again with the same task.

These days, we try to use the full 40-hex object names internally to avoid ambiguity that can arise after rebase starts running. Newly created objects during the rebase may share the same prefix with existing commits listed in the insn sheet. These object names are shortened just before invoking the sequence editor to present the insn sheet to the end user, and then expanded back to full object names when the editor returns. But the code still used the shortened names when preparing the insn sheet for the very first time, resulting "7 hexdigits or more" output to the user.

2014-07-16rebase: omit patch-identical commits with --fork-pointLibravatar John Keeping1-1/+1
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.

2014-04-17rebase: avoid non-function use of "return" on FreeBSDLibravatar Kyle J. McKay1-0/+15
Since a1549e10, 15d4bf2e and 01a1e646 (first appearing in v1.8.4) the git-rebase--*.sh scripts have used a "return" to stop execution of the dot-sourced file and return to the "dot" command that dot-sourced it. The /bin/sh utility on FreeBSD however behaves poorly under some circumstances when such a "return" is executed. In particular, if the "dot" command is contained within a function, then when a "return" is executed by the script it runs (that is not itself inside a function), control will return from the function that contains the "dot" command skipping any statements that might follow the dot command inside that function. Commit 99855ddf (first appearing in v1.8.4.1) addresses this by making the "dot" command the last line in the function. Unfortunately the FreeBSD /bin/sh may also execute some statements in the script run by the "dot" command that appear after the troublesome "return". The fix in 99855ddf does not address this problem. For example, if you have script1.sh with these contents: run_script2() { . "$(dirname -- "$0")/script2.sh" _e=$? echo only this line should show [ $_e -eq 5 ] || echo expected status 5 got $_e return 3 } run_script2 e=$? [ $e -eq 3 ] || { echo expected status 3 got $e; exit 1; } And script2.sh with these contents: if [ 5 -gt 3 ]; then return 5 fi case bad in *) echo always shows esac echo should not get here ! : When running script1.sh (e.g. '/bin/sh script1.sh' or './script1.sh' after making it executable), the expected output from a POSIX shell is simply the single line: only this line should show However, when run using FreeBSD's /bin/sh, the following output appears instead: should not get here expected status 3 got 1 Not only did the lines following the "dot" command in the run_script2 function in script1.sh get skipped, but additional lines in script2.sh following the "return" got executed -- but not all of them (e.g. the "echo always shows" line did not run). These issues can be avoided by not using a top-level "return" in script2.sh. If script2.sh is changed to this: main() { if [ 5 -gt 3 ]; then return 5 fi case bad in *) echo always shows esac echo should not get here ! : } main Then it behaves the same when using FreeBSD's /bin/sh as when using other more POSIX compliant /bin/sh implementations. We fix the git-rebase--*.sh scripts in a similar fashion by moving the top-level code that contains "return" statements into its own function and then calling that as the last line in the script.

2014-03-17rebase -i: do not "echo" random user-supplied stringsLibravatar Uwe Storbeck1-1/+1
In some places we "echo" a string that comes from a commit log message, which may have a backslash sequence that is interpreted by the command (POSIX.1 allows this), most notably "dash"'s built-in 'echo'. A commit message which contains the string '\n' (or ends with the string '\c') may result in a garbage line in the todo list of an interactive rebase which causes the rebase to fail. To reproduce the behavior (with dash as /bin/sh): mkdir test && cd test && git init echo 1 >foo && git add foo git commit -m"this commit message ends with '\n'" echo 2 >foo && git commit -a --fixup HEAD git rebase -i --autosquash --root Now the editor opens with garbage in line 3 which has to be removed or the rebase fails.

2013-11-26remove #!interpreter line from shell librariesLibravatar Jonathan Nieder1-6/+3
In a shell snippet meant to be sourced by other shell scripts, an opening #! line does more harm than good. The harm: - When the shell library is sourced, the interpreter and options from the #! line are not used. Specifying a particular shell can confuse the reader into thinking it is safe for the shell library to rely on idiosyncrasies of that shell. - Using #! instead of a plain comment drops a helpful visual clue that this is a shell library and not a self-contained script. - Tools such as lintian can use a #! line to tell when an installation script has failed by forgetting to set a script executable. This check does not work if shell libraries also start with a #! line. The good: - Text editors notice the #! line and use it for syntax highlighting if you try to edit the installed scripts (without ".sh" suffix) in place. The use of the #! for file type detection is not needed because Git's shell libraries are meant to be edited in source form (with ".sh" suffix). Replace the opening #! lines with comments. This involves tweaking the test harness's valgrind support to find shell libraries by looking for "# " in the first line instead of "#!" (see v1.7.6-rc3~7, 2011-06-17). Suggested by Russ Allbery through lintian. Thanks to Jeff King and Clemens Buchacher for further analysis. Tested by searching for non-executable scripts with #! line: find . -name .git -prune -o -type f -not -executable | while read file do read line <"$file" case $line in '#!'*) echo "$file" ;; esac done The only remaining scripts found are templates for shell scripts (unimplemented.sh, wrap-for-bin.sh) and sample input used in tests (t/t4034/perl/{pre,post}).

2013-08-25rebase -i: fix short SHA-1 collisionLibravatar Junio C Hamano1-0/+30
The 'todo' sheet for interactive rebase shows abbreviated SHA-1's and then performs its operations upon those shortened values. This can lead to an abort if the SHA-1 of a reworded or edited commit is no longer unique within the abbreviated SHA-1 space and a subsequent SHA-1 in the todo list has the same abbreviated value. For example: edit f00dfad first pick badbeef second If, after editing, the new SHA-1 of "first" also has prefix badbeef, then the subsequent 'pick badbeef second' will fail since badbeef is no longer a unique SHA-1 abbreviation: error: short SHA1 badbeef is ambiguous. fatal: Needed a single revision Invalid commit name: badbeef Fix this problem by expanding the SHA-1's in the todo list before performing the operations.

When "merge.log" config is set, "rebase --preserve-merges" will add the log lines to the message of the rebased merge commit. A rebase should not modify a commit message automatically. Teach "git-rebase" to ignore that configuration by passing "--no-log" to the git-merge call. Signed-off-by: Ralf Thielow <ralf.thielow@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
