From 84df4560ed92a771d38081ecca2d40ca35811907 Mon Sep 17 00:00:00 2001 From: Martin von Zweigbergk Date: Sun, 6 Feb 2011 13:43:53 -0500 Subject: [PATCH] rebase: extract code for writing basic state Extract the code for writing the state to rebase-apply/ or rebase-merge/ when a rebase is initiated. This will make it easier to later make both interactive and non-interactive rebase remember the options used. Note that non-interactive rebase stores the sha1 of the original head in a file called orig-head, while interactive rebase stores it in a file called head. Change this by writing to orig-head in both cases. When reading, try to read from orig-head. If that fails, read from head instead. This protects users who upgraded git while they had an ongoing interactive rebase, while still making it possible to remove the code that reads from head at some point in the future.
