Merge branch 'jk/branch-at-publish-rebased' into pu

Give an easier access to the tracking branches from "other" side in
a triangular workflow by introducing B@{publish} that works in a
similar way to how B@{upstream} does.

Meant to be used as a basis for whatever Ram wants to build on.

Will hold.

* jk/branch-at-publish-rebased:
  t1507 (rev-parse-upstream): fix typo in test title
  implement @{publish} shorthand
  branch_get: provide per-branch pushremote pointers
  branch_get: return early on error
  sha1_name: refactor upstream_mark

# Conflicts:
# 	remote.c
Merge branch 'rb/merge-prepare-commit-msg-hook' into pu

Expose more merge states (e.g. $GIT_DIR/MERGE_MODE) to hooks that
run during "git merge".  The log message stresses too much on one
hook, prepare-commit-msg, but it would equally apply to other hooks
like post-merge, I think.

* rb/merge-prepare-commit-msg-hook:
  merge: drop unused arg from abort_commit method signature
  merge: make prepare_to_commit responsible for write_merge_state
  t7505: ensure cleanup after hook blocks merge
  t7505: add missing &&
Merge branch 'po/everyday-doc' into pu

This may make the said command to emit something, but the source is
not meant to be formatted into a manual pages to begin with, and
also its contents are a bit stale.  It may be a good first step in
the right direction, but needs more work to at least get the
mark-up right before public consumption.

Will hold.

* po/everyday-doc:
  Make 'git help everyday' work

* ks/tree-diff-more:
  tree-diff: reuse base str(buf) memory on sub-tree recursion
  tree-diff: no need to call "full" diff_tree_sha1 from show_path()
  tree-diff: rework diff_tree interface to be sha1 based
  tree-diff: remove special-case diff-emitting code for empty-tree cases

  tree-diff: consolidate code for emitting diffs and recursion in one place
  tree-diff: show_tree() is not needed
  tree-diff: no need to pass match to skip_uninteresting()
  tree-diff: no need to manually verify that there is no mode change for a path
  combine-diff: move changed-paths scanning logic into its own function
  combine-diff: move show_log_first logic/action out of paths scanning
Merge branch 'cc/interpret-trailers' into pu

Will replace with the latest one and then merge to 'next'.

* cc/interpret-trailers:
  Documentation: add documentation for 'git interpret-trailers'
  trailer: add tests for commands using env variables
  trailer: set author and committer env variables
  trailer: add tests for trailer command
  trailer: execute command from 'trailer.<name>.command'

  trailer: parse trailers from input file
  trailer: process command line trailer arguments
  trailer: read and process config information
  trailer: process trailers from file and arguments

Merge branch 'jl/submodule-recursive-checkout' into pu

* jl/submodule-recursive-checkout:
  Teach checkout to recursively checkout submodules
  submodule: teach unpack_trees() to update submodules
  submodule: teach unpack_trees() to repopulate submodules
  submodule: teach unpack_trees() to remove submodule contents
  submodule: prepare for recursive checkout of submodules
Merge branch 'hv/submodule-ignore-fix' into pu

Teach "git add" to be consistent with "git status" when changes to
submodules are set to be ignored, to avoid surprises after checking
with "git status" to see there isn't any change to be further added
and then see that "git add ." adds changes to them.

I think a reroll is coming, so this may need to be replaced, but I
needed some practice with heavy conflict resolution.  It conflicts
with two changes to "git add" that have been scheduled for Git 2.0
quite badly, and I think I got the resolution right this time.

* hv/submodule-ignore-fix:
  disable complete ignorance of submodules for index <-> HEAD diff
  always show committed submodules in summary after commit
  teach add -f option for ignored submodules
  fix 'git add' to skip submodules configured as ignored
Merge branch 'kb/fast-hashmap-pack-struct' into pu

I am inclined to drop this; an alternative is to replace it with
the "more portable" one that uses #pragma, which I am willing to
try doing so on 'pu', though.

* kb/fast-hashmap-pack-struct:
  hashmap.h: make sure map entries are tightly packed
Merge branch 'rv/send-email-cache-generated-mid' into pu

* rv/send-email-cache-generated-mid:
  git-send-email: Cache generated message-ids, use them when prompting
  git-send-email: add optional 'choices' parameter to the ask sub
Merge branch 'jk/gitweb-utf8' into pu

Various fixes to gitweb.

Drew Northup volunteered to take a look into this ($gmane/226216)
but nothing seems to have happened since then.

* jk/gitweb-utf8:
  gitweb: Fix broken blob action parameters on blob/commitdiff pages
  gitweb: Don't append ';js=(0|1)' to external links
  gitweb: Make feed title valid utf8
  gitweb: Fix utf8 encoding for blob_plain, blobdiff_plain, commitdiff_plain, and patch
Merge branch 'jc/format-patch' into pu

A new option to send a single patch to the standard output to be
appended at the bottom of a message.  I personally have no need for
this, but it was easy enough to cobble together.  Tests, docs and
stripping out more MIMEy stuff are left as exercises to interested
parties.

* jc/format-patch:
  format-patch: --inline-single
  format-patch: rename "no_inline" field

# Conflicts:
# 	builtin/log.c

* jc/show-branch:
  show-branch: use commit slab to represent bitflags of arbitrary width
  show-branch.c: remove "all_mask"
  show-branch.c: abstract out "flags" operation

  show-branch.c: update comment style

Merge branch 'rj/read-default-config-in-show-ref-pack-refs' into pu

The changes themselves are probably good, but it is unclear what
basic setting needs to be read for which exact operation.

$gmane/228294

* rj/read-default-config-in-show-ref-pack-refs:
  ### DONTMERGE: needs better explanation on what config they need
  pack-refs.c: Add missing call to git_config()

Merge branch 'tr/merge-recursive-index-only' into pu

Will hold.

* tr/merge-recursive-index-only:
  merge-recursive: -Xindex-only to leave worktree unchanged
  merge-recursive: internal flag to avoid touching the worktree
  merge-recursive: remove dead conditional in update_stages()
Merge branch 'tg/perf-lib-test-perf-cleanup' into pu

Add test_perf_cleanup shell function to the perf suite, that allows
the script writers to define a test with a clean-up action.

Will hold.

* tg/perf-lib-test-perf-cleanup:
  perf-lib: add test_perf_cleanup target
  perf-lib: split starting the test from the execution
Merge branch 'yt/shortened-rename' into pu

Attempts to give more weight on the fact that a filepair represents
a rename than showing substring of the actual path when diffstat
lines are not wide enough.

I am not sure if that is solving a right problem, though.

* yt/shortened-rename:
  SQUASH??? style fixes and s/omit/shorten/ where appropriate
  diff.c: keep arrow(=>) on show_stats()'s shortened filename part to make rename visible
Merge branch 'jt/commit-fixes-footer' into pu

There is an ongoing discussion around this topic; in general I am
fairly negative on a new feature that is too narrow and prefer a
more generic solution that can be tailored for specific needs, as
many people stated in the thread.

cc/interpret-trailers could be such a generic solution (although
there don't seem to be much concensus yet).

* jt/commit-fixes-footer:
  commit: Add -f, --fixes <commit> option to add Fixes: line
Merge branch 'jc/create-directories-microopt' into pu

Of unknown value until tested on non-Linux platforms (especially
Windows).

* jc/create-directories-microopt:
  checkout: most of the time we have good leading directories
Merge branch 'bl/blame-full-history' into pu

By disabling the tree-same optimization (which is consistent with
the default behaviour of "git log"-family of commands), make "git
blame" sometimes produce different result from the original code.

Because the "git blame" output can give result for each line from
only one lineage of the history, however, this can be only useful
when you are lucky---unlike "--full-history" of "git log"-family,
where we can show commits from both lineages of histories with an
equal weight.  See $gmane/240392 for more detailed discussion.

* bl/blame-full-history:
  blame: new option --prefer-first to better handle merged cherry-picks
