Before this change the --no-reschedule-failed-exec config option would be overridden by the config. This bug happened because of the particulars of how "rebase" works v.s. most other git commands when it comes to parsing options and config: When we read the config and parse the CLI options we correctly prefer the --no-reschedule-failed-exec option over rebase.rescheduleFailedExec=true in the config. So far so good. However the --reschedule-failed-exec option doesn't take effect when the rebase starts (we'd just create a ".git/rebase-merge/reschedule-failed-exec" file if it was true). It only takes effect when the exec command fails, at which point we'll reschedule the failed "exec" command. Since we only wrote out the positive ".git/rebase-merge/reschedule-failed-exec" under --reschedule-failed-exec, but nothing with --no-reschedule-failed-exec we'll forget that we asked not to reschedule failed "exec", and would happily re-read the config and see that rebase.rescheduleFailedExec=true is set. So the config will effectively override the user having explicitly disabled the option on the command-line. Even more confusingly: Since rebase accepts different options based on its state there wasn't even a way to get around this with "rebase --continue --no-reschedule-failed-exec" (but you could of course set the config with "rebase -c ..."). I think the least bad way out of this is to declare that for such options and config whatever we decide at the beginning of the rebase goes. So we'll now always create either a "reschedule-failed-exec" or a "no-reschedule-failed-exec file at the start, not just the former if we decided we wanted the feature. With this new worldview you can no longer change the setting once a rebase has started except by manually removing the state files discussed above. I think making it work like that is the the least confusing thing we can do. In the future we might want to learn to change the setting in the middle by combining "--edit-todo" with "--[no-]reschedule-failed-exec", we currently don't support combining those options, or any other way to change the state in the middle of the rebase short of manually editing the files in ".git/rebase-merge/*". The bug being fixed here originally came about because of a combination of the behavior of the code added in d421afa0c66 (rebase: introduce --reschedule-failed-exec, 2018-12-10) and the addition of the config variable in 969de3ff0e0 (rebase: add a config option to default to --reschedule-failed-exec, 2018-12-10).
