2015-11-06filter-branch: skip index read/write when possibleJeff King
If the user specifies an index filter but not a tree filter, filter-branch cleverly avoids checking out the tree entirely. But we don't do the next level of optimization: if you have no index or tree filter, we do not need to read the index at all. This can greatly speed up cases where we are only changing the commit objects (e.g., cementing a graft into place). Here are numbers from the newly-added perf test: Test HEAD^ HEAD --------------------------------------------------------------- 7000.2: noop filter 13.81(4.95+0.83) 5.43(0.42+0.43) -60.7% Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>
