From 8cbc57ca1109ba455c6098654b7d732a01fd89fd Mon Sep 17 00:00:00 2001 From: Phil Hord Date: Tue, 28 Apr 2015 18:55:20 -0400 Subject: rebase -i: redo tasks that die during cherry-pick 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. Add a test cases for regression testing to the "rebase-interactive" test suite.
