rebase: omit patch-identical commits with --fork-point

2014-07-16T20:07:40Z

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.

rebase -i: handle "Nothing to do" case with autostash

2014-05-19T22:36:24Z

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. Since this case is unlike the other cases which return control for housekeeping, assign it a special return status and handle that return value explicitly in git-rebase.sh.

git-rebase.sh: use the $( ... ) construct for command substitution

2014-04-23T22:17:02Z

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. The patch was generated by: for _f in $(find . -name "*.sh") do sed -i 's@`$.*$`@$(\1)@g' ${_f} done and then carefully proof-read.

Revert "rebase: fix run_specific_rebase's use of "return" on FreeBSD"

2014-04-17T17:15:27Z

This reverts commit 99855ddf4bd319cd06a0524e755ab1c1b7d39f3b. The workaround 99855ddf introduced to deal with problematic "return" statements in scripts run by "dot" commands located inside functions only handles one part of the problem. The issue has now been addressed by not using "return" statements in this way in the git-rebase--*.sh scripts. This workaround is therefore no longer necessary, so clean up the code by reverting it.
