Hi,
previous rounds (without api) are at $gmane/202752, $gmane/202923,
$gmane/203088 and $gmane/203517, the previous rounds with api were at
$gmane/229732 and $gmane/230210. Thanks to Duy for reviewing the the
last round and Junio and Ramsay for additional comments.
Changes since the previous round:
read-cache: move index v2 specific functions to their own file
- set istate->ops to NULL in discard_index
read-cache: add index reading api
- style fixes
- instead of using internal_ops struct, do for_each_index_entry in
read-cache.c
grep.c: use index api
- remove duplicate call to match_pathspec_depth
ls-files.c: use index api
- load the whole index if there is a trai
documentation: add documentation of the index-v5 file format
- fix typo
- change the position of nfile and ndir in the index file
- document that the conflicts are also stored in the fileentries
block
- document invalid flag
read-cache: read index-v5
- restrict partial loading a bit more, by being more careful when
adjusting the pathspec
- move the ondisk structs from cache.h to read-cache-v5.c
- merge for and while loop in read_entries
- keep a directory tree instead of a flat list when reading the
directories
- ce_queue_push moved to read-cache: write index-v5 using a next_ce
pointer instead of the next pointer that's already used by
name-hash.
- fix reading if there are extensions that are not yet supported
- ignore entries that have the invalid flag set
read-cache: read cache-tree in index-v5
- use the tree structure which is now used in read index-v5
read-cache: write index-v5
- simplify compile_directory_data
changes to the index file format:
- store the number of files before the number of directories in the
header, so that the file command still can recognize the number of
files in the repository correctly.
- store all staged entries in the fileentries block. Doesn't hurt
the performance a lot but simplifies the code.
- add an invalid flag for entries that should be ignored. currently
unused but respected when reading. will be used once the conflict
resolution is done by flipping a bit in the conflict entries at the
end of the index.
added commits:
- read-cache: use fixed width integer types
- read-cache: clear version in discard_index()
- read-cache: Don't compare uid, gid and ino on cygwin
- introduce GIT_INDEX_VERSION environment variable
- test-lib: allow setting the index format version
