I wanted to do v2.15-rc0 today but it seems that this has to slip,
with too many topics still in flight in 'next' among which many are
fixes, one is even a fix for a recent regression.

Docfix.

(merged to 'next' on 2017-09-25 at c7550033df)
+ filter-branch: use hash-object instead of mktag

+ filter-branch: reset $GIT_* before cleaning up

+ parse-options: only insert newline in help text if needed
+ parse-options: write blank line to correct output stream
+ t0040,t1502: Demonstrate parse_options bugs
(merged to 'next' on 2017-09-24 at e479bce0ff)
+ git-rebase: don't ignore unexpected command line arguments
+ rev-parse parseopt: interpret any whitespace as start of help text
+ rev-parse parseopt: do not search help text for flag chars
+ t1502: demonstrate rev-parse --parseopt option mis-parsing

"git filter-branch" cannot reproduce a history with a tag without
the tagger field, which only ancient versions of Git allowed to be
created. This has been corrected.
Recent versions of "git rev-parse --parseopt" did not parse the
option specification that does not have the optional flags (*=?!)
correctly, which has been corrected.


* ik/userdiff-html-h-element-fix (2017-09-24) 1 commit
(merged to 'next' on 2017-09-25 at e3cbe89672)
+ userdiff: fix HTML hunk header regexp
* bw/git-clang-format (2017-10-01) 1 commit
(merged to 'next' on 2017-10-02 at ee84c89b07)
+ clang-format: adjust line break penalties
(this branch is used by sb/git-clang-format.)

The built-in pattern to detect the "function header" for HTML did
not match <H1>..<H6> elements without any attributes, which has
been fixed.


* jc/merge-x-theirs-docfix (2017-09-25) 1 commit
(merged to 'next' on 2017-09-26 at 5a7d954982)
+ merge-strategies: avoid implying that "-s theirs" exists

The documentation for '-X<option>' for merges was misleadingly
written to suggest that "-s theirs" exists, which is not the case.


* jk/describe-omit-some-refs (2017-09-17) 1 commit
(merged to 'next' on 2017-09-24 at c373c71279)
+ describe: fix matching to actually match all patterns
(this branch is used by mk/describe-match-with-all.)

"git describe --match" learned to take multiple patterns in v2.13
series, but the feature ignored the patterns after the first one
and did not work at all. This has been fixed.


* jk/diff-blob (2017-09-22) 1 commit
(merged to 'next' on 2017-09-25 at 38286c8ff5)
+ cat-file: handle NULL object_context.path

"git cat-file --textconv" started segfaulting recently, which
has been corrected.


* jk/doc-read-tree-table-asciidoctor-fix (2017-09-24) 1 commit
(merged to 'next' on 2017-09-25 at 070163b964)

A docfix.


* jk/fallthrough (2017-09-22) 3 commits
(merged to 'next' on 2017-09-25 at ad96c37620)
+ consistently use "fallthrough" comments in switches
+ curl_trace(): eliminate switch fallthrough
+ test-line-buffer: simplify command parsing

Many codepaths have been updated to squelch -Wimplicit-fallthrough
warnings from Gcc 7 (which is a good code hygiene).


* jm/status-ignored-directory-optim (2017-09-19) 1 commit
(merged to 'next' on 2017-09-24 at ca50f5ed41)
+ Improve performance of git status --ignored

"git status --ignored", when noticing that a directory without any
tracked path is ignored, still enumerated all the ignored paths in
the directory, which is unnecessary. The codepath has been
optimized to avoid this overhead.


* js/win32-lazyload-dll (2017-09-26) 1 commit
(merged to 'next' on 2017-09-26 at 04577bf1c5)
+ Win32: simplify loading of DLL functions

Add a helper in anticipation for its need in a future topic RSN.


* jt/fast-export-copy-modify-fix (2017-09-21) 1 commit
(merged to 'next' on 2017-09-24 at c02bfe1902)
+ fast-export: do not copy from modified file

"git fast-export" with -M/-C option issued "copy" instruction on a
path that is simultaneously modified, which was incorrect.


* ks/doc-use-camelcase-for-config-name (2017-09-25) 1 commit
(merged to 'next' on 2017-09-26 at 7b4d2115af)

+ leak_pending: use `object_array_clear()`, not `free()`
+ commit: fix memory leak in `reduce_heads()`

Memory leaks in various codepaths have been plugged.


* mk/describe-match-with-all (2017-09-20) 2 commits

+ describe: teach --match to handle branches and remotes
+ Merge branch 'jk/describe-omit-some-refs' into mk/describe-match-with-all

"git describe --match <pattern>" has been taught to play well with
the "--all" option.


* mk/diff-delta-avoid-large-offset (2017-08-11) 1 commit
(merged to 'next' on 2017-09-26 at b4983ac027)
+ diff-delta: do not allow delta offset truncation

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.


* mk/diff-delta-uint-may-be-shorter-than-ulong (2017-08-10) 1 commit
(merged to 'next' on 2017-09-26 at 0ccd9346d7)
+ diff-delta: fix encoding size that would not fit in "unsigned int"

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.


* rj/no-sign-compare (2017-09-22) 4 commits
(merged to 'next' on 2017-09-25 at 71ee264ce6)
+ ALLOC_GROW: avoid -Wsign-compare warnings
+ cache.h: hex2chr() - avoid -Wsign-compare warnings
+ commit-slab.h: avoid -Wsign-compare warnings
+ git-compat-util.h: xsize_t() - avoid -Wsign-compare warnings

Many codepaths have been updated to squelch -Wsign-compare
warnings.


* rs/mailinfo-qp-decode-fix (2017-09-24) 1 commit
(merged to 'next' on 2017-09-25 at d48c594041)
+ mailinfo: don't decode invalid =XY quoted-printable sequences

"git mailinfo" was loose in decoding quoted printable and produced
garbage when the two letters after the equal sign are not
hexadecimal. This has been fixed.


* rs/resolve-ref-optional-result (2017-09-24) 3 commits

+ refs: pass NULL to resolve_ref_unsafe() if hash is not needed
+ refs: pass NULL to refs_resolve_ref_unsafe() if hash is not needed
+ refs: make sha1 output parameter of refs_resolve_ref_unsafe() optional

Code clean-up.


* sb/doc-config-submodule-update (2017-09-24) 1 commit

* sb/merge-commit-msg-hook (2017-09-22) 1 commit
(merged to 'next' on 2017-09-25 at 096e0502a8)
+ Documentation/githooks: mention merge in commit-msg hook

As "git commit" to conclude a conflicted "git merge" honors the
commit-msg hook, "git merge" that records a merge commit that
cleanly auto-merges should, but it didn't.
* sb/merge-commit-msg-hook (2017-09-22) 1 commit
(merged to 'next' on 2017-09-25 at 096e0502a8)
+ Documentation/githooks: mention merge in commit-msg hook

Add documentation for a topic that has recently graduated to the
'master' branch.

* er/fast-import-dump-refs-on-checkpoint (2017-09-29) 2 commits
- SQUASH???
- fast-import: checkpoint: dump branches/tags/marks even if object_count==0

The checkpoint command "git fast-import" did not flush updates to
refs and marks unless at least one object was created since the
last checkpoint, which has been corrected, as these things can
happen without any new object getting created.

* mh/mmap-packed-refs (2017-09-25) 21 commits

+ 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

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.

- builtin/: add UNLEAKs

Many variables that points at a region of memory that will live

+ fast-import: checkpoint: dump branches/tags/marks even if object_count==0

Doc updates.
The checkpoint command "git fast-import" did not flush updates to
refs and marks unless at least one object was created since the
last checkpoint, which has been corrected, as these things can
happen without any new object getting created.

Will merge to 'master'.

- technical doc: add a design doc for hash function transition

Lay out plans for weaning us off of SHA-1.

- mru: use double-linked list from list.h

The first step to getting rid of mru API and using the

Needs review.
Outreachy.

Backports a moral equivalent of 2015 fix to the poll emulation from
the upstream gnulib to fix occasional breakages on HPE NonStop.

Needs review.

Recent versions of "git rev-parse --parseopt" did not parse the
option specification that does not have the optional flags (*=?!)
correctly, which has been corrected.

Looking mostly ready. Further comments?

* 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

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.

Will merge to 'master'.

. colors: git_default_config() does not read color.ui
. Revert "color: check color.ui in git_default_config()"

Recent tip of 'master' and 'maint' (at least as of v2.14.2) has a
regression in "git add -p" for those who set ui.color=always in
their configuration, caused by us being overly aggressive in
allowing plumbing commands to honor the configuration to fix a
fallout from an earlier change that made everybody, even the
plumbing commands, to automatically color its output by default.
Revert it for now from the released version (and to be released
one) until we come up with a different fix to the problem.

"git branch" learned "-c/-C" to create and switch to a new branch
by copying an existing one.

Will merge to 'master'.
