- + filter-branch: stash away ref map in a branch

+* mh/mmap-packed-refs (2017-09-25) 21 commits
+  (merged to 'next' on 2017-09-29 at 3639417666)
+ + packed-backend.c: rename a bunch of things and update comments
+ + mmapped_ref_iterator: inline into `packed_ref_iterator`
+ + ref_cache: remove support for storing peeled values
+ + packed_ref_store: get rid of the `ref_cache` entirely
+ + ref_store: implement `refs_peel_ref()` generically
+ + packed_read_raw_ref(): read the reference from the mmapped buffer
+ + packed_ref_iterator_begin(): iterate using `mmapped_ref_iterator`
+ + read_packed_refs(): ensure that references are ordered when read
+ + packed_ref_cache: keep the `packed-refs` file mmapped if possible
+ + packed-backend.c: reorder some definitions
+ + mmapped_ref_iterator_advance(): no peeled value for broken refs
+ + mmapped_ref_iterator: add iterator over a packed-refs file
+ + packed_ref_cache: remember the file-wide peeling state
+ + read_packed_refs(): read references with minimal copying
+ + read_packed_refs(): make parsing of the header line more robust
+ + read_packed_refs(): only check for a header at the top of the file
+ + read_packed_refs(): use mmap to read the `packed-refs` file
+ + die_unterminated_line(), die_invalid_line(): new functions
+ + packed_ref_cache: add a backlink to the associated `packed_ref_store`
+ + prefix_ref_iterator: break when we leave the prefix
+ + ref_iterator: keep track of whether the iterator output is ordered
 
- "git fast-export" with -M/-C option issued "copy" instruction on a
- path that is simultaneously modified, which was incorrect.
+ Operations that do not touch (majority of) packed refs have been
+ optimized by making accesses to packed-refs file lazy; we no longer
+ pre-parse everything, and an access to a single ref in the
+ packed-refs does not touch majority of irrelevant refs, either.

+  (merged to 'next' on 2017-09-28 at 497214603c)
+ + t7406: submodule.<name>.update command must not be run from .gitmodules
 
- The delta format used in the packfile cannot reference data at
- offset larger than what can be expressed in 4-byte, but the
- generator for the data failed to make sure the offset does not
- overflow.  This has been corrected.
 
+* sd/branch-copy (2017-09-24) 4 commits

- + diff-delta: fix encoding size that would not fit in "unsigned int"
+ "git branch" learned "-c/-C" to create a new branch by copying an
+ existing one.
 
- The machinery to create xdelta used in pack files received the
- sizes of the data in size_t, but lost the higher bits of them by
- storing them in "unsigned int" during the computation, which is
- fixed.
