Merge branch 'nd/split-index'
An experiment to use two files (the base file and incremental changes relative to it) to represent the index to reduce I/O cost of rewriting a large index when only small part of the working tree changes. * nd/split-index: (32 commits) t1700: new tests for split-index mode t2104: make sure split index mode is off for the version test read-cache: force split index mode with GIT_TEST_SPLIT_INDEX read-tree: note about dropping split-index mode or index version read-tree: force split-index mode off on --index-output rev-parse: add --shared-index-path to get shared index path update-index --split-index: do not split if $GIT_DIR is read only update-index: new options to enable/disable split index mode split-index: strip pathname of on-disk replaced entries split-index: do not invalidate cache-tree at read time split-index: the reading part split-index: the writing part read-cache: mark updated entries for split index read-cache: save deleted entries in split index read-cache: mark new entries for split index read-cache: split-index mode read-cache: save index SHA-1 after reading entry.c: update cache_changed if refresh_cache is set in checkout_entry() cache-tree: mark istate->cache_changed on prime_cache_tree() cache-tree: mark istate->cache_changed on cache tree update ...
