Here are the topics that have been cooking.  Commits prefixed with
'-' are only in 'pu' (proposed updates) while commits prefixed with
'+' are in 'next'.  The ones marked with '.' do not appear in any of
the integration branches, but I am still holding onto them.

We may have to start thinking about 2.10.2; there are about a dozen
and half fixes accumulated on the 'maint' front.

You can find the changes described here in the integration branches
of the repositories listed at

* da/mergetool-diff-order (2016-10-11) 4 commits
  (merged to 'next' on 2016-10-11 at 3d1b98c16d)
 + mergetool: honor -O<orderfile>
 + mergetool: honor diff.orderFile
 + mergetool: move main program flow into a main() function
 + mergetool: add copyright

 "git mergetool" learned to honor "-O<orderfile>" to control the
 order of paths to present to the end user.

* dt/http-empty-auth (2016-10-04) 1 commit
  (merged to 'next' on 2016-10-10 at 10b7b0a6a5)
 + http: http.emptyauth should allow empty (not just NULL) usernames

 http.emptyauth configuration is a way to allow an empty username to
 pass when attempting to authenticate using mechanisms like
 Kerberos.  We took an unspecified (NULL) username and sent ":"
 (i.e. no username, no password) to CURLOPT_USERPWD, but did not do
 the same when the username is explicitly set to an empty string.

* jk/alt-odb-cleanup (2016-10-10) 18 commits
  (merged to 'next' on 2016-10-10 at d2ed6b6d21)
 + alternates: use fspathcmp to detect duplicates
 + sha1_file: always allow relative paths to alternates
 + count-objects: report alternates via verbose mode
 + fill_sha1_file: write into a strbuf
 + alternates: store scratch buffer as strbuf
 + fill_sha1_file: write "boring" characters
 + alternates: use a separate scratch space
 + alternates: encapsulate alt->base munging
 + alternates: provide helper for allocating alternate
 + alternates: provide helper for adding to alternates list
 + link_alt_odb_entry: refactor string handling
 + link_alt_odb_entry: handle normalize_path errors
 + t5613: clarify "too deep" recursion tests
 + t5613: do not chdir in main process
 + t5613: whitespace/style cleanups
 + t5613: use test_must_fail
 + t5613: drop test_valid_repo function
 + t5613: drop reachable_via function
 (this branch is used by jk/quarantine-received-objects.)

 Codepaths involved in interacting alternate object store have
 been cleaned up.

* jk/clone-copy-alternates-fix (2016-10-05) 1 commit
  (merged to 'next' on 2016-10-10 at 8154134c8c)
 + clone: detect errors in normalize_path_copy

 "git clone" of a local repository can be done at the filesystem
 level, but the codepath did not check errors while copying and
 adjusting the file that lists alternate object stores.

* jk/quarantine-received-objects (2016-10-10) 5 commits
  (merged to 'next' on 2016-10-10 at 0fd3e3b2ef)
 + tmp-objdir: do not migrate files starting with '.'
 + tmp-objdir: put quarantine information in the environment
 + receive-pack: quarantine objects until pre-receive accepts
 + tmp-objdir: introduce API for temporary object directories
 + check_connected: accept an env argument
 (this branch uses jk/alt-odb-cleanup.)

 In order for the receiving end of "git push" to inspect the
 received history and decide to reject the push, the objects sent
 from the sending end need to be made available to the hook and
 the mechanism for the connectivity check, and this was done
 traditionally by storing the objects in the receiving repository
 and letting "git gc" to expire it.  Instead, store the newly
 received objects in a temporary area, and make them available by
 reusing the alternate object store mechanism to them only while we
 decide if we accept the check, and once we decide, either migrate
 them to the repository or purge them immediately.

* jk/ref-symlink-loop (2016-10-10) 2 commits
  (merged to 'next' on 2016-10-11 at ac5c35f87f)
 + files_read_raw_ref: prevent infinite retry loops in general
 + files_read_raw_ref: avoid infinite loop on broken symlinks

 A stray symbolic link in $GIT_DIR/refs/ directory could make name
 resolution loop forever, which has been corrected.

* js/regexec-buf (2016-10-10) 1 commit
  (merged to 'next' on 2016-10-11 at 466a26548c)
 + configure.ac: improve description of NO_REGEX test

 A follow-up to an already graduated topic.

* js/reset-usage (2016-10-11) 1 commit
  (merged to 'next' on 2016-10-11 at 61ad4a7c0e)
 + reset: fix usage

 Message fix-up.

* nd/commit-p-doc (2016-10-05) 1 commit
  (merged to 'next' on 2016-10-10 at 5a9996dd7b)
 + git-commit.txt: clarify --patch mode with pathspec

 Documentation for "git commit" was updated to clarify that "commit
 -p <paths>" adds to the current contents of the index to come up
 with what to commit.

* rs/cocci (2016-10-10) 2 commits
  (merged to 'next' on 2016-10-11 at bbd6a88402)
 + use strbuf_add_unique_abbrev() for adding short hashes, part 3
 + remove unnecessary NULL check before free(3)

 Code cleanup.

* rs/pretty-format-color-doc-fix (2016-10-11) 1 commit
  (merged to 'next' on 2016-10-11 at f0ae64bcbd)
 + pretty: fix document link for color specification

 Small doc update.

* sb/submodule-config-doc-drop-path (2016-10-11) 1 commit
  (merged to 'next' on 2016-10-11 at 28fc3e53f9)
 + documentation: improve submodule.<name>.{url, path} description

 The "submodule.<name>.path" stored in .gitmodules is never copied
 to .git/config and such a key in .git/config has no meaning, but
 the documentation described it and submodule.<name>.url next to
 each other as if both belong to .git/config.  This has been fixed.

* dk/worktree-dup-checkout-with-bare-is-ok (2016-10-14) 1 commit
  (merged to 'next' on 2016-10-17 at 24594d3e56)
 + worktree: allow the main brach of a bare repository to be checked out

 In a worktree connected to a repository elsewhere, created via "git
 worktree", "git checkout" attempts to protect users from confusion
 by refusing to check out a branch that is already checked out in
 another worktree.  However, this also prevented checking out a
 branch, which is designated as the primary branch of a bare
 reopsitory, in a worktree that is connected to the bare
 repository.  The check has been corrected to allow it.

 Will merge to 'master'.

* jc/cocci-xstrdup-or-null (2016-10-12) 1 commit
  (merged to 'next' on 2016-10-17 at 55ceaa465a)
 + cocci: refactor common patterns to use xstrdup_or_null()

 Code cleanup.

 Will merge to 'master'.

* tb/convert-stream-check (2016-10-12) 2 commits
 - convert.c: stream and fast search for binary
 - read-cache: factor out get_sha1_from_index() helper

 End-of-line conversion sometimes needs to see if the current blob
 in the index has NULs and CRs to base its decision.  We used to
 always get a full statistics over the blob, but in many cases we
 can return early when we have seen "enough" (e.g. if we see a
 single NUL, the blob will be handled as binary).  The codepaths
 have been optimized by using streaming interface.

 Waiting for review.

* jk/ambiguous-short-object-names (2016-10-12) 1 commit
 - t1512: become resilient to GETTEXT_POISON build

 A test fixup to recently graduated topic.

 Will merge to 'next'.

* jk/merge-base-fork-point-without-reflog (2016-10-12) 1 commit
 - merge-base: handle --fork-point without reflog

 "git rebase" immediately after "git clone" failed to find the fork
 point from the upstream.

 Will merge to 'next'.

* jk/upload-pack-use-prio-queue (2016-10-11) 1 commit
 - upload-pack: use priority queue in reachable() check

 Code clean-up and performance improvement to reduce use of
 timestamp-ordered commit-list by replacing it with a priority
 queue.

 Will merge to 'next'.

* jk/fetch-quick-tag-following (2016-10-14) 1 commit
 - fetch: use "quick" has_sha1_file for tag following

 When fetching from a remote that has many tags that are irrelevant
 to branches we are following, we used to waste way too many cycles 
 when checking if the object pointed at by a tag (that we are not
 going to fetch!) exists in our repository too carefully.

 Will merge to 'next'.

* jt/trailer-with-cruft (2016-10-14) 6 commits
 - trailer: support values folded to multiple lines
 - trailer: allow non-trailers in trailer block
 - trailer: make args have their own struct
 - trailer: streamline trailer item create and add
 - trailer: use list.h for doubly-linked list
 - trailer: improve const correctness

 Update "interpret-trailers" machinery and teaches it that people in
 real world write all sorts of crufts in the "trailer" that was
 originally designed to have the neat-o "Mail-Header: like thing"
 and nothing else.

 Waiting for review.

* mm/send-email-cc-cruft-after-address (2016-10-14) 1 commit
 - parse_mailboxes: accept extra text after <...> address

 "git send-email" attempts to pick up valid e-mails from the
 trailers, but people in real world write non-addresses there, like
 "Cc: Stable <add@re.ss> # 4.8+", which broke the output depending
 on the availability and vintage of Mail::Address perl module.

 Will merge to 'next'.

* jc/bundle (2016-03-03) 6 commits
 - index-pack: --clone-bundle option
 - Merge branch 'jc/index-pack' into jc/bundle
 - bundle v3: the beginning
 - bundle: keep a copy of bundle file name in the in-core bundle header
 - bundle: plug resource leak
 - bundle doc: 'verify' is not about verifying the bundle

 The beginning of "split bundle", which could be one of the
 ingredients to allow "git clone" traffic off of the core server
 network to CDN.

 While I think it would make it easier for people to experiment and
 build on if the topic is merged to 'next', I am at the same time a
 bit reluctant to merge an unproven new topic that introduces a new
 file format, which we may end up having to support til the end of
 time.  It is likely that to support a "prime clone from CDN", it
 would need a lot more than just "these are the heads and the pack
 data is over there", so this may not be sufficient.

 Will discard.

* mh/connect (2016-06-06) 10 commits
 - connect: [host:port] is legacy for ssh
 - connect: move ssh command line preparation to a separate function
 - connect: actively reject git:// urls with a user part
 - connect: change the --diag-url output to separate user and host
 - connect: make parse_connect_url() return the user part of the url as a separate value
 - connect: group CONNECT_DIAG_URL handling code
 - connect: make parse_connect_url() return separated host and port
 - connect: re-derive a host:port string from the separate host and port variables
 - connect: call get_host_and_port() earlier
 - connect: document why we sometimes call get_port after get_host_and_port

 Rewrite Git-URL parsing routine (hopefully) without changing any
 behaviour.

 It has been two months without any support.  We may want to discard
 this.

* kn/ref-filter-branch-list (2016-05-17) 17 commits
 - branch: implement '--format' option
 - branch: use ref-filter printing APIs
 - branch, tag: use porcelain output
 - ref-filter: allow porcelain to translate messages in the output
 - ref-filter: add `:dir` and `:base` options for ref printing atoms

 - ref-filter: introduce symref_atom_parser() and refname_atom_parser()
 - ref-filter: introduce refname_atom_parser_internal()
 - ref-filter: make "%(symref)" atom work with the ':short' modifier
 - ref-filter: add support for %(upstream:track,nobracket)
 - ref-filter: make %(upstream:track) prints "[gone]" for invalid upstreams
 - ref-filter: introduce format_ref_array_item()
 - ref-filter: move get_head_description() from branch.c
 - ref-filter: modify "%(objectname:short)" to take length
 - ref-filter: implement %(if:equals=<string>) and %(if:notequals=<string>)
 - ref-filter: include reference to 'used_atom' within 'atom_value'
 - ref-filter: implement %(if), %(then), and %(else) atoms

 The code to list branches in "git branch" has been consolidated
 with the more generic ref-filter API.

 Rerolled.
 Needs review.

* ec/annotate-deleted (2015-11-20) 1 commit

 Follow-on to dk/gc-idx-wo-pack topic, to clean up stale
 .bitmap and .keep files.

 Has been waiting for a reroll for too long.

 . WIPWIP
 . WIP: diff-b-m
 - diffcore-rename: allow easier debugging
 - diffcore-rename.c: add locate_rename_src()
 - diffcore-break: allow debugging

 "git diff -B -M" produced incorrect patch when the postimage of a
 completely rewritten file is similar to the preimage of a removed
 file; such a resulting file must not be expressed as a rename from
 other place.

 The fix in this patch is broken, unfortunately.

 Will discard.

 A minor regression fix for "git submodule".

 It seems that POSIX emulation layer of Windows is not cooperating;

* jk/abbrev-auto (2016-10-03) 1 commit
 - find_unique_abbrev: move logic out of get_short_sha1()
 (this branch uses lt/abbrev-auto.)

 Updates the way approximate count of total objects is computed
 while attempting to come up with a unique abbreviated object name,
 which in turn needs to estimate how many hexdigits are necessary to
 ensure uniqueness.

 Undecided.

* nd/ita-empty-commit (2016-09-28) 3 commits
 - commit: don't be fooled by ita entries when creating initial commit
 - diff-lib.c: enable --shift-ita in index_differs_from()
 - Resurrect "diff-lib.c: adjust position of i-t-a entries in diff"

 When new paths were added by "git add -N" to the index, it was
 enough to circumvent the check by "git commit" to refrain from
 making an empty commit without "--allow-empty".  The same logic
 prevented "git status" to show such a path as "new file" in the
 "Changes not staged for commit" section.

 Expecting a reroll.

 + abbrev: prepare for new world order
 + abbrev: add FALLBACK_DEFAULT_ABBREV to prepare for auto sizing
 (this branch is used by jk/abbrev-auto.)

 Allow the default abbreviation length, which has historically been
 7, to scale as the repository grows.  The logic suggests to use 12
 hexdigits for the Linux kernel, and 9 to 10 for Git itself.

 was not rich enough to differentiate a signature made by an expired
 key, a signature made by a revoked key, etc.  New output letters
 have been assigned to express them.

 Will merge to 'master'.

  (merged to 'next' on 2016-10-17 at f5c20df38b)
 + wt-status: begin error messages with lower-case
 + wt-status: teach has_{unstaged,uncommitted}_changes() about submodules
 + wt-status: export also the has_un{staged,committed}_changes() functions
 + wt-status: make the require_clean_work_tree() function reusable
 + pull: make code more similar to the shell script again
 + pull: drop confusing prefix parameter of die_on_unclean_work_tree()

 The require_clean_work_tree() helper was recreated in C when "git
 pull" was rewritten from shell; the helper is now made available to
 other callers in preparation for upcoming "rebase -i" work.

* bw/ls-files-recurse-submodules (2016-10-10) 4 commits
  (merged to 'next' on 2016-10-17 at f0e398946a)
 + ls-files: add pathspec matching for submodules
 + ls-files: pass through safe options for --recurse-submodules
 + ls-files: optionally recurse into submodules
 + git: make super-prefix option

 "git ls-files" learned "--recurse-submodules" option that can be
 used to get a listing of tracked files across submodules (i.e. this
 only works with "--cached" option, not for listing untracked or
 ignored files).  This would be a useful tool to sit on the upstream
 side of a pipe that is read with xargs to work on all working tree
 files from the top-level superproject.

 Will merge to 'master'.

 - contrib/long-running-filter: add long running filter example
 - convert: add filter.<driver>.process option
 - convert: prepare filter.<driver>.process option
 - convert: make apply_filter() adhere to standard Git error handling
 - pkt-line: add functions to read/write flush terminated packet streams
 - pkt-line: add packet_write_gently()
 - pkt-line: add packet_flush_gently()
 - pkt-line: add packet_write_fmt_gently()
 - pkt-line: extract set_packet_header()
 - pkt-line: rename packet_write() to packet_write_fmt()
 - run-command: add clean_on_exit_handler
 - run-command: move check_pipe() from write_or_die to run_command
 - convert: modernize tests
 - convert: quote filter names in error messages

 The smudge/clean filter API expect an external process is spawned
 to filter the contents for each path that has a filter defined.  A
 new type of "process" filter API has been added to allow the first
 request to run the filter for a path to spawn a single process, and
 all filtering need is served by this single process for multiple
 paths, reducing the process creation overhead.

* hv/submodule-not-yet-pushed-fix (2016-10-10) 3 commits
 - batch check whether submodule needs pushing into one call
 - serialize collection of refs that contain submodule changes
 - serialize collection of changed submodules

 The code in "git push" to compute if any commit being pushed in the
 superproject binds a commit in a submodule that hasn't been pushed
 out was overly inefficient, making it unusable even for a small
 project that does not have any submodule but have a reasonable
 number of refs.

 Waiting for review.

* sg/fix-versioncmp-with-common-suffix (2016-09-08) 5 commits
 - versioncmp: cope with common leading parts in versionsort.prereleaseSuffix
 - versioncmp: pass full tagnames to swap_prereleases()
 - t7004-tag: add version sort tests to show prerelease reordering issues
 - t7004-tag: use test_config helper
 - t7004-tag: delete unnecessary tags with test_when_finished

 The prereleaseSuffix feature of version comparison that is used in
 "git tag -l" did not correctly when two or more prereleases for the
 same release were present (e.g. when 2.0, 2.0-beta1, and 2.0-beta2
 are there and the code needs to compare 2.0-beta1 and 2.0-beta2).

 Waiting for a reroll.

* sb/push-make-submodule-check-the-default (2016-10-10) 2 commits
 - push: change submodule default to check when submodules exist
 - submodule add: extend force flag to add existing repos

 Turn the default of "push.recurseSubmodules" to "check" when
 submodules seem to be in use.

* jc/pull-rebase-ff (2016-07-28) 1 commit
 - pull: fast-forward "pull --rebase=true"

 "git pull --rebase", when there is no new commits on our side since
 we forked from the upstream, should be able to fast-forward without
 invoking "git rebase", but it didn't.

 Needs a real log message and a few tests.

* ex/deprecate-empty-pathspec-as-match-all (2016-06-22) 1 commit
  (merged to 'next' on 2016-09-21 at e19148ea63)
 + pathspec: warn on empty strings as pathspec

 Originally merged to 'next' on 2016-07-13

 An empty string used as a pathspec element has always meant
 'everything matches', but it is too easy to write a script that
 finds a path to remove in $path and run 'git rm "$paht"', which
 ends up removing everything.  Start warning about this use of an
 empty string used for 'everything matches' and ask users to use a
 more explicit '.' for that instead.

 The hope is that existing users will not mind this change, and
 eventually the warning can be turned into a hard error, upgrading
 the deprecation into removal of this (mis)feature.

 Will hold to see if people scream.

 + merge: drop 'git merge <message> HEAD <commit>' syntax

 Stop supporting "git merge <message> HEAD <commit>" syntax that has
 been deprecated since October 2007, and issues a deprecation
 warning message since v2.5.0.

 It has been reported that git-gui still uses the deprecated syntax,
 which needs to be fixed before this final step can proceed.
