Merge branch 'jc/grep-pcre-loose-ends' into pu

"git log -F -E --grep='<ere>'" failed to use the given <ere>
pattern as extended regular expression, and instead looked for the
string literally.  The early part of this series is a fix for it.

The last two are very wrong and need to be redone by refactoring
the configuration handling of "grep.*" part.

* jc/grep-pcre-loose-ends:
  log: honor grep.* configuration
  log --grep: accept --basic-regexp and --perl-regexp
  log --grep: use the same helper to set -E/-F options as "git grep"
  revisions: initialize revs->grep_filter using grep_init()
  grep: move pattern-type bits support to top-level grep.[ch]
  grep: move the configuration parsing logic to grep.[ch]
  builtin/grep.c: make configuration callback more reusable
Merge branch 'fa/vcs-svn' into pu

A follow-up to a GSoC project, but seems not quite ready.
Will discard.

* fa/vcs-svn:
  vcs-svn: remove repo_tree
  vcs-svn/svndump: rewrite handle_node(), begin|end_revision()
  vcs-svn/svndump: restructure node_ctx, rev_ctx handling
  svndump: move struct definitions to .h
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.
Will discard.

* 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

	builtin/pack-objects.c

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 'jc/xprm-generation' into pu

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

Stalled mostly due to lack of responses.

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

  pretty: support %C(auto[,N]) to turn on coloring on next placeholder(s)
  pretty: split parsing %C into a separate function
  pretty: share code between format_decoration and show_decorations
Merge branch 'as/check-ignore' into pu

  Update directory listing API doc to match code
Merge branch 'jk/lua-hackery' into pu

Interesting exercise. When we do this for real, we probably would want
to wrap a commit to make it more like an "object" with methods like
"parents", etc.

* jk/lua-hackery:
  pretty: fix up one-off format_commit_message calls
  Minimum compilation fixup
  Makefile: make "lua" a bit more configurable
  add a "lua" pretty format
  add basic lua infrastructure
  pretty: make some commit-parsing helpers more public

Conflicts:
	pretty.c
Merge branch 'nd/attr-match-optim-more' into pu

Start laying the foundation to build the "wildmatch" after we can
agree on its desired semantics.

* nd/attr-match-optim-more:
  attr: more matching optimizations from .gitignore
  gitignore: make pattern parsing code a separate function

Conflicts:
	dir.c

Need to address the installation half if this is to be any useful.
