Merge branch 'er/doc-fast-import-done' into pu

Parked in 'pu' in case ESR responds with "Sorry, forgot to sign-off".

* er/doc-fast-import-done:
  fast-import: document the --done option
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.

Waiting for a Tested-by.

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

"git checkout -b --opt y" errors out saying that creating a new
branch to check it out and grabbing contents for paths out of a
commit are incompatible operations.  While it is technically correct
(the command line wants to create a new branch whose name is "--opt"
and check it out, and there shouldn't be anything else left on the
command line, but there is "y"), "--opt" is not a valid name of the
branch to begin with, so even without "y", the command will not
succeed.  Treat this case specially to complain that "--opt" is not
a valid branch name.

* nd/checkout-branch-name-check:
  checkout: verify new branch name's validity early
Merge branch 'jc/merge-bases' into pu

Optimises the "merge-base" computation a bit, and also updates its
users that do not need the full merge-base information to call a
cheaper subset.  The most important one is the second from the tip
done by Thomas.

Needs sign-off.

* jc/merge-bases:
  get_merge_bases_many(): walk from many tips in parallel
  in_merge_bases(): omit unnecessary redundant common ancestor reduction
  http-push: use in_merge_bases() for fast-forward check
  receive-pack: use in_merge_bases() for fast-forward check
  in_merge_bases(): support only one "other" commit
Merge branch 'jc/add-delete-default' into pu

"git add dir/" updated modified files and added new files, but does
not notice removed files, which may be "Huh?" to some users.  They
can of course use "git add -A dir/", but why should they?

Resurrected from graveyard, as I thought it was a worthwhile thing
to do in the longer term; waiting for comments.

* jc/add-delete-default:
  git add: notice removal of tracked paths by default
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.

Anybody interested in fixing 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 '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 'ph/credential-refactor' into pu

Adds a new credential helper to support Gnome keyring and attempts
to refactor to share code among OSX keychain, Gnome keyring and
Win32 credential helpers.

Waiting for test results with the tip one
to decide whether the series should be rerolled or reduced to only
the first one.

* ph/credential-refactor:
  wincred: port to generic credential helper (UNTESTED)
  osxkeychain: port to generic credential helper implementation
  gnome-keyring: port to generic helper implementation
  contrib: add generic credential helper
  contrib: add credential helper for GnomeKeyring

  Pass nr_heads to filter_refs() by reference
  Pass nr_heads to everything_local() by reference
  Pass nr_heads to do_pack_ref() by reference
  Let fetch_pack() inform caller about number of unique heads
  filter_refs(): do not check the same head_pos twice
  fetch-pack.c: name local variables more consistently
  fetch_pack(): reindent function decl and defn

Merge branch 'cn/branch-set-upstream-to' into pu

"git branch --set-upstream origin/master" is a common mistake to
create a local branch 'origin/master' and set it to integrate with
the current branch.  With a plan to deprecate this option, introduce
"git branch (-u|--set-upstream-to) origin/master" that sets the
current branch to integrate with 'origin/master' remote tracking
branch.

Wainting for a reroll
that tightens its error checking.

* cn/branch-set-upstream-to:
  branch: deprecate --set-upstream and show help if we detect possible mistaken use
  branch: add --unset-upstream option
  branch: introduce --set-upstream-to

The tip ones should be squashed in.
Waiting for a reroll.

  vcs-svn/svndump: restructure node_ctx, rev_ctx handling
  svndump: move struct definitions to .h
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.

* jl/submodule-rm:
  Teach rm to remove submodules unless they contain a git directory
Merge branch 'js/compat-itimer' into pu

Pieces to support compilation on __TANDEM.

* js/compat-itimer:
  Support for setitimer() on platforms lacking it

Conflicts:

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.

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
