  silence git gc --auto --quiet output
Merge branch 'jk/no-more-pre-exec-callback' into pu

(Originally merged to 'next' on 2012-07-23)

Will defer until the end of the 2012.
while waiting for older "less" to go extinct.

* jk/no-more-pre-exec-callback:
  pager: drop "wait for output to run less" hack
Merge branch 'mk/maint-graph-infinity-loop' into pu

The --graph code fell into infinite loop when asked to do what the
code did not expect ;-)

Anybody who worked on --graph wants to comment?

* mk/maint-graph-infinity-loop:
  graph.c: infinite loop in git whatchanged --graph -m
Merge branch 'nd/wildmatch' into pu

Allows pathname patterns in .gitignore and .gitattributes files
with double-asterisks "foo/**/bar" to match any number of directory
hiearchies.

It was pointed out that some symbols that do not have to be global
are left global.
Will wait for a reroll.

Merge branch 'tx/relative-in-the-future' into pu

Not my itch; rewritten an earlier submission by Tom Xue into
somewhat more maintainable form, though it breaks existing i18n.

Waiting for a voluteer to fix it up.
Otherwise may discard.

* tx/relative-in-the-future:
  date: show relative dates in the future
  date: refactor the relative date logic from presentation
Merge branch 'jc/maint-push-refs-all' into pu

Allows pushing and fetching everything including refs/stash.
This is broken (see the log message there).

Not ready.

* jc/maint-push-refs-all:
  get_fetch_map(): tighten checks on dest refs
  [BROKEN] fetch/push: allow refs/*:refs/*
Merge branch 'jx/test-real-path' into pu

Running tests with the "trash" directory elsewhere with the "--root"
option did not work well if the directory was specified by a symbolic
link pointing at it.

Seems broken as it makes $(pwd) and TRASH_DIRECTORY inconsistent.
Needs rerolling.

* jx/test-real-path:
  test: set the realpath of CWD as TRASH_DIRECTORY
Merge branch 'as/test-tweaks' into pu

Various minor tweaks to the test framework to paint its output
lines in colors that match what they mean better.

Has the "is this really blue?" issue Peff raised resolved???

* as/test-tweaks:
  tests: paint unexpectedly fixed known breakages in bold red
  tests: test the test framework more thoroughly
  [SQUASH] t/t0000-basic.sh: quoting of TEST_DIRECTORY is screwed up
  tests: refactor mechanics of testing in a sub test-lib
  tests: paint skipped tests in bold blue
  tests: test number comes first in 'not ok $count - $message'
  tests: paint known breakages in bold yellow
Merge branch 'ms/contrib-thunderbird-updates' into pu

Update helper to send out format-patch output using Thunderbird.
Seems to have design regression for silent users.

* ms/contrib-thunderbird-updates:
  [SQUASH] minimum fixup
  Thunderbird: fix appp.sh format problems
Merge branch 'mb/remote-default-nn-origin' into pu

When the user does not specify what remote to interact with, we
often attempt to use 'origin'.  This can now be customized via a
configuration variable.

Expecting a reroll.

"The first remote becomes the default" bit is better done as a
separate step.

* mb/remote-default-nn-origin:
  Teach get_default_remote to respect remote.default.
  Test that plain "git fetch" uses remote.default when on a detached HEAD.
  Teach clone to set remote.default.
  Teach "git remote" about remote.default.
  Teach remote.c about the remote.default configuration setting.
  Rename remote.c's default_remote_name static variables.

Conflicts:
	builtin/remote.c
	t/t5505-remote.sh
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 long time 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" fanbois, 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

Conflicts:
	builtin/pack-objects.c
	streaming.c
	t/t1050-large.sh
Merge branch 'ph/credential-refactor' into pu

Attempts to refactor to share code among OSX keychain, Gnome keyring
and Win32 credential helpers.

* ph/credential-refactor:
  wincred: port to generic credential helper
  osxkeychain: port to generic credential helper implementation
  gnome-keyring: port to generic helper implementation
  contrib: add generic credential helper
Merge branch 'jl/submodule-rm' into pu

"git rm submodule" cannot blindly remove a submodule directory as
its working tree may have local changes, and worse yet, it may even
have its repository embedded in it.  Teach it some special cases
where it is safe to remove a submodule, specifically, when there is
no local changes in the submodule working tree, and its repository
is not embedded in its working tree but is elsewhere and uses the
gitfile mechanism to point at it.

Replacement sent but was still iffy around conflicted merge cases.

* jl/submodule-rm:
  Teach rm to remove submodules unless they contain a git directory
Merge branch 'jc/xprm-generation' into pu

A toy to analyze how bad the clock skews are in histories of real
world projects.

* jc/xprm-generation:
  test-generation: compute generation numbers and clock skews
Merge branch 'nd/pretty-placeholder-with-color-option' into pu

Rerolled, but haven't picked it up yet.

* nd/pretty-placeholder-with-color-option:
  [SQUASH] do not use real-sb without initializing
  pretty: support right alignment
  pretty: support placeholders %C+ and %C-
  pretty: share code between format_decoration and show_decorations
Merge branch 'as/check-ignore' into pu

Expecting a further reroll to follow-up review comments.

* as/check-ignore:
  [SQUASH-FIX] 283d072 (Add git-check-ignore sub-command, 2012-09-20)

Merge branch 'da/mergetool-custom' into pu

The actual external command to run for mergetool backend can be
specified with difftool/mergetool.$name.cmd configuration
variables, but this mechanism was ignored for the backends we
natively support.

Will merge to 'next'.

* da/mergetool-custom:
  mergetool--lib: Allow custom commands to override built-ins
Merge branch 'rr/test-use-shell-path-not-shell' into pu
