When running "fetch -q", a long silence while the sender side
computes the set of objects to send can be mistaken by proxies as
dropped connection.  The server side has been taught to send a small
empty messages to keep the connection alive.

* jk/upload-pack-keepalive:
  upload-pack: bump keepalive default to 5 seconds
  upload-pack: send keepalive packets during pack computation

Instead of typing four capital letters "HEAD", you can say "@" now,
e.g. "git log @".

* fc/at-head:
  Add new @ shortcut for HEAD
  sha1-name: pass len argument to interpret_branch_name()

"git check-ignore" follows the same rule as "git add" and "git
status" in that the ignore/exclude mechanism does not take effect
on paths that are already tracked.  With "--no-index" option, it
can be used to diagnose which paths that should have been ignored
have been mistakenly added to the index.

* dw/check-ignore-sans-index:
  check-ignore: Add option to ignore index contents

From the commit log template, remove irrelevant "advice" messages
that are shared with "git status" output.

* mm/commit-template-squelch-advice-messages:
  commit: disable status hints when writing to COMMIT_EDITMSG
  wt-status: turn advice_status_hints into a field of wt_status
  commit: factor status configuration is a helper function

Give "update-refs" a "--stdin" option to read multiple update
requests and perform them in an all-or-none fashion.

* bk/refs-multi-update:
  update-ref: add test cases covering --stdin signature
  update-ref: support multiple simultaneous updates
  refs: add update_refs for multiple simultaneous updates
  refs: add function to repack without multiple refs
  refs: factor delete_ref loose ref step into a helper
  refs: factor update_ref steps into helpers
  refs: report ref type from lock_any_ref_for_update
  reset: rename update_refs to reset_refs

Just like "make -C <directory>", make "git -C <directory> ..." to
go there before doing anything else.

* nr/git-cd-to-a-directory:
  t0056: "git -C" test updates
  git: run in a directory given with -C option

Work around a bug in FreeBSD shell that caused a regression to "git
rebase" in v1.8.4.  May need to be later applied to 'maint'.

* mm/rebase-continue-freebsd-WB:
  rebase: fix run_specific_rebase's use of "return" on FreeBSD

Fix a minor regression in v1.8.3.2 and later that made it
impossible to base your local work on anything but a local branch
of the upstream repository you are tracking from.

* jh/checkout-auto-tracking:
  t3200: fix failure on case-insensitive filesystems
  branch.c: Relax unnecessary requirement on upstream's remote ref name
  t3200: Add test demonstrating minor regression in 41c21f22
  Refer to branch.<name>.remote/merge when documenting --track
  t3200: Minor fix when preparing for tracking failure
  t2024: Fix &&-chaining and a couple of typos

When the webserver responds with "405 Method Not Allowed", it
should tell the client what methods are allowed with the "Allow"
header.

* bc/http-backend-allow-405:
  http-backend: provide Allow header for 405

Micro optimize hash function used in the object hash table.

* np/lookup-object-hashing:
  lookup_object: remove hashtable_index() and optimize hash_obj()

Just like "git checkout -" knows to check out and "git merge -"
knows to merge the branch you were previously on, "git cherry-pick"
now understands "git cherry-pick -" to pick from the previous
branch.

* hu/cherry-pick-previous-branch:
  cherry-pick: allow "-" as abbreviation of '@{-1}'

"git status" now omits the prefix to make its output a comment in a
commit log editor, which is not necessary for human consumption.

We may want to tighten the output to omit unnecessary trailing blank
lines, but that does not have to be in the scope of this series.

* mm/status-without-comment-char:
  t7508: avoid non-portable sed expression
  status: add missing blank line after list of "other" files
  tests: don't set status.displayCommentPrefix file-wide
  status: disable display of '#' comment prefix by default
  submodule summary: ignore --for-status option
  wt-status: use argv_array API
  builtin/stripspace.c: fix broken indentation

Make "foo^{tag}" to peel a tag to itself, i.e. no-op., and fail if
"foo" is not a tag.  "git rev-parse --verify v1.0^{tag}" would be a
more convenient way to say "test $(git cat-file -t v1.0) = tag".

* rh/peeling-tag-to-tag:
  peel_onion: do not assume length of x_type globals
  peel_onion(): add support for <rev>^{tag}

"git branch -v -v" (and "git status") did not distinguish among a
branch that does not build on any other branch, a branch that is in
sync with the branch it builds on, and a branch that is configured
to build on some other branch that no longer exists.

* jx/branch-vv-always-compare-with-upstream:
  status: always show tracking branch even no change
  branch: report invalid tracking branch as gone

When there is no sufficient overlap between old and new history
during a fetch into a shallow repository, we unnecessarily sent
objects the sending side knows the receiving end has.

* nd/fetch-into-shallow:
  Add testcase for needless objects during a shallow fetch
  list-objects: mark more commits as edges in mark_edges_uninteresting
  list-objects: reduce one argument in mark_edges_uninteresting
  upload-pack: delegate rev walking in shallow fetch to pack-objects
  shallow: add setup_temporary_shallow()
  shallow: only add shallow graft points to new shallow file
  move setup_alternate_shallow and write_shallow_commits to shallow.c

* jk/config-int-range-check:
  compat/mingw.h: define PRId64

Provide PRId64 alongside PRIuMAX.

Instead of repeating the text to record as the commit log message
and string we expect to see in "log" output, use the same variable
to avoid them going out of sync.

Use different names for test files in different directories to
improve our chance to catch future breakages that makes "-C <dir>"
go to a place that is different from what was specified.

Some people still use rather old versions of bash, which cannot grok
some constructs like 'printf -v varname' the prompt and completion
code started to use recently.

* bc/completion-for-bash-3.0:
  contrib/git-prompt.sh: handle missing 'printf -v' more gracefully
  t9902-completion.sh: old Bash still does not support array+=('') notation
  git-completion.bash: use correct Bash/Zsh array length syntax

Fixes a minor bug in "git rebase -i" (there could be others, as the
root cause is pretty generic) where the code feeds a random, data
dependeant string to 'echo' and expects it to come out literally.

* mm/no-shell-escape-in-die-message:
  die_with_status: use "printf '%s\n'", not "echo"

* jl/some-submodule-config-are-not-boolean:
  avoid segfault on submodule.*.path set to an empty "true"

Output from "git log --full-diff -- <pathspec>" looked strange,
because comparison was done with the previous ancestor that touched
the specified <pathspec>, causing the patches for paths outside the
pathspec to show more than the single commit has changed.

* tr/log-full-diff-keep-true-parents:
  log: use true parents for diff when walking reflogs
  log: use true parents for diff even when rewriting

The auto-tag-following code in "git fetch" tries to reuse the same
transport twice when the serving end does not cooperate and does
not give tags that point to commits that are asked for as part of
the primary transfer.  Unfortunately, Git-aware transport helper
interface is not designed to be used more than once, hence this
does not work over smart-http transfer.

* jc/transport-do-not-use-connect-twice-in-fetch:
  builtin/fetch.c: Fix a sparse warning
  fetch: work around "transport-take-over" hack
  fetch: refactor code that fetches leftover tags
  fetch: refactor code that prepares a transport
  fetch: rename file-scope global "transport" to "gtransport"
  t5802: add test for connect helper

Send a large request to read(2)/write(2) as a smaller but still
reasonably large chunks, which would improve the latency when the
operation needs to be killed and incidentally works around broken
64-bit systems that cannot take a 2GB write or read in one go.

* sp/clip-read-write-to-8mb:
  Revert "compat/clipped-write.c: large write(2) fails on Mac OS X/XNU"
  xread, xwrite: limit size of IO to 8MB

* jk/mailmap-incomplete-line:
  mailmap: handle mailmap blobs without trailing newlines

While normalizing a URL, we forgot that the buffer that holds it
could be relocated when it grows, which was a brown-paper-bag bug
that can lead to a crash introduced on 'master' post 1.8.4 release.

  urlmatch.c: recompute pointer after append_normalized_escapes

"git cvsserver" computed the permission mode bits incorrectly for
executable files.

When send-email comes up with an error message to die with upon

"git-svn" used with SVN 1.8.0 when talking over https:// connection
dumped core due to a bug in the serf library that SVN uses.  Work
it around on our side, even though the SVN side is being fixed.

* uh/git-svn-serf-fix:
  git-svn: fix termination issues for remote svn connections

* fc/contrib-bzr-hg-fixes:
  contrib/remote-helpers: quote variable references in redirection targets

The implementation of "add -i" has a crippling code to work around
ActiveState Perl limitation but it by mistake also triggered on Git

* ks/p4-view-spec:
  git p4: implement view spec wildcards with "p4 where"
  git p4 test: sanitize P4CHARSET

A packfile that stores the same object more than once is broken and
will be rejected by "git index-pack" that is run when receiving data
over the wire.

* jk/duplicate-objects-in-packs:
  t5308: check that index-pack --strict detects duplicate objects
  test index-pack on packs with recoverable delta cycles
  add tests for indexing packs with delta cycles
  sha1-lookup: handle duplicate keys with GIT_USE_LOOKUP
  test-sha1: add a binary output mode

We made sure that we notice the user-supplied GIT_DIR is actually a
gitfile, but did not do the same when the default ".git" is a gitfile.

* nd/git-dir-pointing-at-gitfile:
  Make setup_git_env() resolve .git file when $GIT_DIR is not specified

If a build-time fallback is set to "cat" instead of "less", we
should apply the same "no subprocess or pipe" optimization as we
apply to user-supplied GIT_PAGER=cat.
