Merge branch 'da/p4merge-mktemp' into pu

Create an empty file in $TMPDIR instead of using an empty file in
the local directory (but why?).

* da/p4merge-mktemp:
  mergetools/p4merge: Honor $TMPDIR for the /dev/null placeholder
Merge branch 'er/python-version-requirements' into pu

Will merge to 'next' after getting an Ack on the top-squash.

* er/python-version-requirements:
  (squash???) remote-helpers/git/__init__.py needs sys before checking sys.hexversion
  Python scripts: check minimum compatible version after auditing
Merge branch 'mb/gitweb-highlight-link-target' into pu

Expecting a reroll.

* mb/gitweb-highlight-link-target:
  Highlight the link target line in Gitweb using CSS
Merge branch 'mp/complete-paths' into pu

The completion script used to let the default completer to suggest
pathnames, which gave too many irrelevant choices (e.g. "git add"
would not want to add an unmodified path).  Teach it to use a more
git-aware logic to enumerate only relevant ones.

Waiting for area-experts review.

* mp/complete-paths:
  git-completion.bash: add support for path completion

Conflicts:
	contrib/completion/git-completion.bash
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 'jc/maint-name-rev' into pu

"git name-rev" names the given revision based on a ref that can be
reached in the smallest number of steps from the rev, but that is
not useful when the caller wants to know which tag is the oldest one
that contains the rev.  This teaches a new mode to the command that
uses the oldest ref among those which contain the rev.

I am not sure if this is worth it; for one thing, even with the help
from notes-cache, it seems to make the "describe --contains" even
slower. Also the command will be unusably slow for a user who does
not have a write access (hence unable to create or update the
notes-cache).

Stalled mostly due to lack of responses.

* jc/maint-name-rev:
  describe --contains: use "name-rev --algorithm=weight"
  name-rev --algorithm=weight: tests and documentation
  name-rev --algorithm=weight: cache the computed weight in notes
  name-rev --algorithm=weight: trivial optimization
  name-rev: --algorithm option
  name_rev: clarify the logic to assign a new tip-name to a commit
  name-rev: lose unnecessary typedef

Conflicts:
	builtin/name-rev.c
Merge branch 'fc/remote-bzr' into pu

New remote helper for bzr (v3).  With minor fixes, this may be ready
for 'next'.

* fc/remote-bzr:
  (fixup) test-bzr.sh: fix multi-line string assignment
  remote-bzr: detect local repositories
  remote-bzr: add support for older versions of bzr

  Add new remote-bzr transport helper
Merge branch 'fc/remote-testgit-feature-done' into pu

Needs review and Ack (or Nack) from people involved in the remote
helper interface for this to move forward.

* fc/remote-testgit-feature-done:
  remote-testgit: properly check for errors
Merge branch 'mo/cvs-server-updates' into pu

Needs review by folks interested in cvsserver.

* mo/cvs-server-updates:
  t9402: Use TABs for indentation
  t9402: Rename check.cvsCount and check.list

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 re-roll.

"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:

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 '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
Merge branch 'jc/doc-default-format' into pu

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

* jc/doc-default-format:
  [SQAUSH] allow "cd Doc* && make DEFAULT_DOC_TARGET=..."
  Allow generating a non-default set of documentation
Merge branch 'as/check-ignore' into pu

Duy helped to reroll this.

Expecting a re-roll.

* as/check-ignore:

Merge branch 'jc/doc-maintainer' into pu

An early draft that is still incomplete.

* jc/doc-maintainer:
  update "howto maintain git"
Merge branch 'zk/clean-report-failure' into pu

"git clean" states what it is going to remove and then goes on to
remove it, but sometimes it only discovers things that cannot be
removed after recursing into a directory, which makes the output
confusing and even wrong.

* zk/clean-report-failure:
  git-clean: Display more accurate delete messages

Conflicts:
	dir.c
Merge branch 'jc/merge-blobs' (early part) into pu

* 'jc/merge-blobs' (early part):
  merge-tree: add comments to clarify what these functions are doing
  merge-tree: lose unused "resolve_directories"
  merge-tree: lose unused "flags" from merge_list
  Which merge_file() function do you mean?
Merge branch 'rj/maint-cygwin-say-color' into pu

Even though I do not think of a cleaner way to do this, I am not
happy with the way how $GIT_TEST_PRINT and $GIT_TEST_PRINT_LN are
interpolated into the command line with token splitting at $IFS.

Will discard, per discussion with the author.

* rj/maint-cygwin-say-color:
  tests: Allow customization of how say_color() prints
Merge branch 'jc/unpack-file-in-tmpdir' into pu

Throw-away "how about this" to teach unpack-file to use $TMPDIR to
store its output.

Will discard.

* jc/unpack-file-in-tmpdir:
  unpack-file: allow output to be in $TMPDIR
