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.
v2.8-rc0 has been tagged; this is a preview for the next release.
In previous cycles, I often left many topics in 'next' when tagging
this zero-th preview, but eventually merged them before the final.
I decided to do things a bit differently for this cycle: a topic,
once it hits 'next', will not be rewound and only refined and
corrected with incremental updates, so the only effect such a late
merge to 'master' before the final is that some topics are not as
widely tested on 'master' before the final one is tagged.
So this -rc0 is deliberately aggressive in that it includes all
topics that have been cooking in 'next' that I think we can fix bugs
that might still lurking in them before the final (it merges 25
topics since the last batch to 'master'). The topics not merged to
this preview, on the other hand, will not be considered for 2.8
final, even though I might later succumb to the temptation to pick
up ones that are in 'next' as of today ;-)
You can find the changes described here in the integration branches of the
repositories listed at

+ credential-cache--daemon: disallow relative socket path
+ credential-cache--daemon: refactor check_socket_directory
The "credential-cache" daemon process used to run in whatever
directory it happened to start in, but this made umount(2)ing the
filesystem that houses the repository harder; now the process
chdir()s to the directory that house its own socket on startup.

"git merge-tree" used to mishandle "both sides added" conflict with
its own "create a fake ancestor file that has the common parts of

been updated to use the usual "3-way merge with an empty blob as
the fake common ancestor file" approach used in the rest of the

(merged to 'next' on 2016-02-25 at ca8cbb0)
+ tests: rename work-tree tests to *work-tree*
Traditionally, the tests that try commands that work on the
contents in the working tree were named with "worktree" in their
filenames, but with the recent addition of "git worktree"
subcommand, whose tests are also named similarly, it has become
harder to tell them apart. The traditional tests have been renamed
to use "work-tree" instead in an attempt to differentiate them.
* mm/push-default-warning (2016-02-25) 1 commit

(merged to 'next' on 2016-02-25 at 1e412f0)
+ submodule: try harder to fetch needed sha1 by direct fetching sha1
When "git submodule update" did not result in fetching the commit
object in the submodule that is referenced by the superproject, the
command learned to retry another fetch, specifically asking for
that commit that may not be connected to the refs it usually
fetches.
* sb/submodule-module-list-fix (2016-02-24) 1 commit
(merged to 'next' on 2016-02-25 at 21be607)
+ submodule helper list: respect correct path prefix
A helper function "git submodule" uses since v2.7.0 to list the
modules that match the pathspec argument given to its subcommands
(e.g. "submodule add <repo> <path>") has been fixed.

The internal API to interact with "remote.*" configuration
variables has been streamlined.

* jk/credential-clear-config (2016-02-26) 1 commit
- credential: let empty credential specs reset helper list
The credential.helper configuration variable is cumulative and
there is no good way to override it from the command line. As
a special case, giving an empty string as its value now serves
as the signal to clear the values specified in various files.
* jk/submodule-c-credential (2016-02-25) 1 commit
- git: submodule honor -c credential.* from command line

propagate configuration variables related to credential helper
down to the submodules.

* js/am-3-merge-recursive-direct (2015-10-12) 2 commits
- am: make a direct call to merge_recursive
- merge_recursive_options: introduce the "gently" flag
The merge_recursive_generic() function has been made a bit safer to
call from inside a process. "git am -3" was taught to make a direct
call to the function when falling back to three-way merge.
Being able to make a direct call would be good in general, but as a
performance thing, the change needs to be backed up by numbers.
Needs review.
I haven't gone through the "gently" change with fine toothed comb;
I can see that the change avoids calling die(), but I haven't made
sure that the program states (e.g. what's in the in-core index) are
adjusted sensibly when it returns to the caller instead of dying,
or the codepaths that used to die() are free of resource leaks.
The original code certainly did not care the program states at the
point of dying exactly because it knew it is going to exit, but now
they have to care, and they need to be audited.

. 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.

- upload-pack: add deepen-since to cut shallow repos based on time
- shallow.c: implement a generic shallow boundary finder based on rev-list
- fetch-pack: use a separate flag for fetch in deepening mode
- fetch-pack: use a common function for verbose printing
- fetch-pack: use skip_prefix() instead of starts_with()
- upload-pack: move rev-list code out of check_non_tip()
- upload-pack: tighten number parsing at "deepen" lines
- upload-pack: use skip_prefix() instead of starts_with()
- upload-pack: move "unshallow" sending code out of deepen()

- upload-pack: move shallow deepen code out of receive_needs()
- transport-helper.c: refactor set_helper_option()
- remote-curl.c: convert fetch_git() to use argv_array
The existing "git fetch --depth=<n>" option was hard to use
correctly when making the history of an existing shallow clone
deeper. A new option, "--deepen=<n>", has been added to make this
easier to use. "git clone" also learned "--shallow-since=<date>"
and "--shallow-exclude=<tag>" options to make it easier to specify
"I am interested only in the recent N months worth of history" and
"Give me only the history since that version".
Needs review.
* jk/pack-idx-corruption-safety (2016-02-25) 3 commits

+ use_pack: handle signed off_t overflow
+ nth_packed_object_offset: bounds-check extended offset
+ t5313: test bounds-checks of corrupted/malicious pack/idx files
The code to read the pack data using the offsets stored in the pack
idx file has been made more carefully check the validity of the
data in the idx.
Will merge to 'master'.

+ t: add tests for diff.renames (true/false/unset)
+ t4001-diff-rename: wrap file creations in a test
+ Documentation/diff-config: fix description of diff.renames
The end-user facing Porcelain level commands like "diff" and "log"

"git p4 submit" attempts to do a rebase, which would fail if done

"git commit --dry-run" reported "No, no, you cannot commit." in one

(this branch is used by dt/refs-backend-lmdb and sb/submodule-init.)
A major part of "git submodule update" has been ported to C to take
advantage of the recently added framework to run download tasks in
