Merge branch 'jc/ls-files-i-dir' into pu

"git ls-files --exclude=t -i" did not consider anything under t/
as excluded, as it did not pay attention to exclusion of leading
paths while walking the index.  Other two users of excluded() are
also updated.

Not urgent; probably early post 1.7.11.

* jc/ls-files-i-dir:
  dir.c: make excluded() file scope static
  unpack-trees.c: use path_excluded() in check_ok_to_remove()
  builtin/add.c: use path_excluded()
  path_excluded(): update API to less cache-entry centric
Merge branch 'nd/stream-index-pack' into pu

Use streaming API to read from the object store to avoid having to hold
a large blob object in-core while running index-pack.

Not urgent; probably early post 1.7.11.

By Nguyễn Thái Ngọc Duy
* nd/stream-index-pack:
  index-pack: use streaming interface for collision test on large blobs
  index-pack: factor out unpack core from get_data_from_pack
  index-pack: use streaming interface on large blobs (most of the time)
  index-pack: hash non-delta objects while reading from stream
Merge branch 'nd/stream-pack-objects' into pu

Not urgent; probably early post 1.7.11.

  pack-objects: use streaming interface for reading large loose blobs
Merge branch 'jk/no-more-pre-exec-callback' into pu

On hold for 6 months until ancient "less" goes extinct.

* jk/no-more-pre-exec-callback:
  pager: drop "wait for output to run less" hack
Merge branch 'mm/push-default-switch-warning' into pu

Will merge to next after 1.7.11.

Hopwefully we can have a solidly tested series early in 1.7.12 or
1.7.13 at the latest.

By Matthieu Moy
* mm/push-default-switch-warning:
  push: start warning upcoming default change for push.default
Merge branch 'js/submodule-relative' into pu

Makes "git submodule" deal with nested submodule structure where a
module is contained within a module whose origin is specified as a
relative URL to its superproject's origin.

Not urgent; probably early post 1.7.11.

By Jon Seymour
* js/submodule-relative:
  submodule: fix handling of superproject origin URLs like foo, ./foo and ./foo/bar
  submodule: fix sync handling of some relative superproject origin URLs
  submodule: document failure to handle relative superproject origin URLs
  submodule: additional regression tests for relative URLs
Merge branch 'jk/no-op-push-message' into pu

Rewords the status message of "git push" that pushed only one ref
differently from "Everything up-to-date", to give a bit more help to
people who get the message when their current branch is not pushed.

By Jeff King
* jk/no-op-push-message:
  improve no-op push output
Merge branch 'nl/http-proxy-more' into pu

I queued only the later two patches from this series, even though they do
not make much sense without the first one that seems to need a bit more
work, so that we won't forget.

By Jeff King (1) and Nelson Benitez Leon (1)
* nl/http-proxy-more:
  http: rename HTTP_REAUTH to HTTP_AUTH_RETRY
  http: Avoid limit of retrying request only twice
Merge branch 'sg/bash-prompt' into pu

This is only the "correction" bits taken from the beginning of a larger
series that is to be rerolled.  The first two are tangled with Felipe's
topic so a reroll, if comes, should build on top of them.

By SZEDER Gábor
* sg/bash-prompt:
  completion: respect $GIT_DIR
  completion: use __gitdir() in _git_log()
  tests: add tests for the bash prompt functions in the completion script
  tests: move code to run tests under bash into a helper library
Merge branch 'fc/git-prompt-script' into pu

The last remaining sticking point is what to do with the duplicated shell
function.

By Felipe Contreras
* fc/git-prompt-script:
  completion: split __git_ps1 into a separate script
  completion: remove executable mode
Merge branch 'jc/run-hook-env-1' into pu

Not urgent.

Updates run_hook() API to be much less specific to "commit".  It would
only be useful if people start doing more interesting things with hooks.

* jc/run-hook-env-1:
  run_hook(): enhance the interface to pass arbitrary environment
Merge branch 'jc/apply-3way' into pu

"git apply" learns to wiggle the base version and perform three-way merge
when a patch does not exactly apply to the version you have.

It turns out that it is somewhat unpleasant to handle add/add conflicts in
this code, but it seems necessary if we want to use "apply -3" to replace
the use of "apply --build-fake-ancestor" followed by the slow "merge" in
"am -3".

* jc/apply-3way:
  apply -3: add failing test for add/add conflicts
  apply: fix an incomplete message
  apply: refactor "previous patch" logic
  apply: a bit more comments on PATH_TO_BE_DELETED
  apply: document --3way option
  apply: allow rerere() upon --3way results
  apply: register conflicted stages to the index
  apply: plug the three-way merge logic in
  apply: fall back on three-way merge
  apply: accept -3/--3way command line option
  apply: split load_preimage() helper function out
  apply: refactor read_file_or_gitlink()
  apply: clear_image() clears things a bit more

Conflicts:
	builtin/apply.c
Merge branch 'jc/maint-push-refs-all' into pu

Allows pushing and fetching refs/stash.
Not ready.
There still seem to be other bugs hiding (e.g. try pushing twice).

* jc/maint-push-refs-all:
  get_fetch_map(): tighten checks on dest refs
  fetch/push: allow refs/*:refs/*
Merge branch 'jc/split-blob' into pu

Not ready.

I finished the streaming checkout codepath, but as explained in
127b177 (bulk-checkin: support chunked-object encoding, 2011-11-30),
these are still early steps of a long and painful journey. At least
pack-objects and fsck need to learn the new encoding for the series
to be usable locally, and then index-pack/unpack-objects needs to
learn it to be used remotely.

Given that I heard a lot of noise that people want large files, and
that I was asked by somebody at GitTogether'11 privately for an
advice on how to pay developers (not me) to help adding necessary
support, I am somewhat dissapointed that the original patch series
that was sent almost two months ago still remains here without much
comments and updates from the developer community. I even made the
interface to the logic that decides where to split chunks easily
replaceable, and I deliberately made the logic in the original patch
extremely stupid to entice others, especially the "bup" fanboys, to
come up with a better logic, thinking that giving people an easy
target to shoot for, they may be encouraged to help out. The plan is
not working :-(.

* jc/split-blob:
  chunked-object: streaming checkout
  chunked-object: fallback checkout codepaths
  bulk-checkin: support chunked-object encoding
  bulk-checkin: allow the same data to be multiply hashed
  new representation types in the packstream
  packfile: use varint functions

	builtin/pack-objects.c
	streaming.c
