From cfc5789ada444423232fa1533f401b5972eb3f6c Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 25 Dec 2009 00:30:51 -0800 Subject: resolve-undo: record resolved conflicts in a new index extension section When resolving a conflict using "git add" to create a stage #0 entry, or "git rm" to remove entries at higher stages, remove_index_entry_at() function is eventually called to remove unmerged (i.e. higher stage) entries from the index. Introduce a "resolve_undo_info" structure and keep track of the removed cache entries, and save it in a new index extension section in the index_state. Operations like "read-tree -m", "merge", "checkout [-m] " and "reset" are signs that recorded information in the index is no longer necessary. The data is removed from the index extension when operations start; they may leave conflicted entries in the index, and later user actions like "git add" will record their conflicted states afresh.
