From fc4a6735ee10b7699c22dfb58a9dd40f225e51bd Mon Sep 17 00:00:00 2001 From: Phillip Wood Date: Tue, 19 Mar 2019 19:03:07 +0000 Subject: sequencer: always discard index after checkout As the checkout runs in a separate process our index will be out of date so it should be discarded. The existing callers are not doing this consistently so do it here to avoid the callers having to worry about it. This fixes some test failures that happen if do_interactive_rebase() is called without forking rebase--interactive which we will implement shortly. Running git rebase -i master topic starting on master created empty todo lists because all the commits in topic were marked as cherry-picks. After topic was checked out in prepare_branch_to_be_rebased() the working tree contained the contents from topic but the index contained master and the cache entries were still valid. This meant that diff_populate_filespec() which loads the blobs when calculating patch-id's ended up reading the contents for master from the working tree which actually contained topic.

Using a string for onto, restrict_revision and upstream, was a hangover from the scripted version of rebase. The functions that use these variables are updated to take a `struct commit`.
