Junio C Hamano 7ba06bc3d0 Merge branch 'pw/rebase-i-internal'

  rebase: use a common action enum
  rebase -i: use struct rebase_options in do_interactive_rebase()
  rebase -i: use struct rebase_options to parse args
  rebase -i: use struct object_id for squash_onto
  rebase -i: use struct commit when parsing options
  rebase -i: remove duplication
  rebase -i: combine rebase--interactive.c with rebase.c
  rebase: use OPT_RERERE_AUTOUPDATE()
  rebase: rename write_basic_state()
  rebase: don't translate trace strings
  sequencer: always discard index after checkout

Junio C Hamano 2bfb182bc5 Merge branch 'ew/repack-with-bitmaps-by-default'
The connectivity bitmaps are created by default in bare
repositories now; also the pathname hash-cache is created by
default to avoid making crappy deltas when repacking.

* ew/repack-with-bitmaps-by-default:
  pack-objects: default to writing bitmap hash-cache
  t5310: correctly remove bitmaps for jgit test

Junio C Hamano 5b51f0d38d Merge branch 'js/partial-clone-connectivity-check'
During an initial "git clone --depth=..." partial clone, it is
pointless to spend cycles for a large portion of the connectivity
check that enumerates and skips promisor objects (which by
definition is all objects fetched from the other side).  This has
been optimized out.

* js/partial-clone-connectivity-check:
  t/perf: add perf script for partial clones
  clone: do faster object check for partial clones

Junio C Hamano caa227ff45 Merge branch 'js/misc-doc-fixes'

which has been corrected.

Junio C Hamano ce2a18f2b1 Merge branch 'cc/replace-graft-peel-tags'
When given a tag that points at a commit-ish, "git replace --graft"
failed to peel the tag before writing a replace ref, which did not
make sense because the old graft mechanism the feature wants to
mimick only allowed to replace one commit object with another.

Junio C Hamano 4ab701b2ee Merge branch 'km/empty-repo-is-still-a-repo'
Running "git add" on a repository created inside the current
repository is an explicit indication that the user wants to add it
as a submodule, but when the HEAD of the inner repository is on an
unborn branch, it cannot be added as a submodule.  Worse, the files
in its working tree can be added as if they are a part of the outer
repository, which is not what the user wants.  These problems are
being addressed.

Junio C Hamano 96379f043f Merge branch 'en/merge-directory-renames'
"git merge-recursive" backend recently learned a new heuristics to
infer file movement based on how other files in the same directory
moved.  As this is inherently less robust heuristics than the one
based on the content similarity of the file itself (rather than
based on what its neighbours are doing), it sometimes gives an
outcome unexpected by the end users.  This has been toned down to
leave the renamed paths in higher/conflicted stages in the index so
that the user can examine and confirm the result.

* en/merge-directory-renames:
  merge-recursive: switch directory rename detection default
  merge-recursive: give callers of handle_content_merge() access to contents
  merge-recursive: track information associated with directory renames

Josh Steadmon dfa33a298d clone: do faster object check for partial clones
For partial clones, doing a full connectivity check is wasteful; we skip
promisor objects (which, for a partial clone, is all known objects), and
enumerating them all to exclude them from the connectivity check can
take a significant amount of time on large repos.

At most, we want to make sure that we get the objects referred to by any
wanted refs. For partial clones, just check that these objects were
transferred.

Phillip Wood 460bc3ce73 rebase -i: run without forking rebase--interactive
When the builtin rebase starts an interactive rebase it parses the
options and then repackages them and forks
`rebase--interactive`. Separate the option parsing in
cmd_rebase__interactive() from the business logic to allow interactive
rebases can be run without forking `rebase__interactive` by calling
run_rebase_interactive() directly.

Starting interactive rebases without forking makes it easy to debug
the sequencer without worrying about attaching to child
processes. Ævar has also reported that some of the rebase perf tests
are 30% faster [1].

This patch also makes it easy to remove cmd_rebase__interactive() in
the future when git-legacy-rebase.sh and
git-rebase--preserve-merges.sh are retired.

them.

Phillip Wood 0609b741a4 rebase -i: combine rebase--interactive.c with rebase.c
In order to run `rebase -i` without forking `rebase--interactive` it
will be convenient to have all the code from rebase--interactive.c in
rebase.c. This is a straight forward copy of the code from
rebase--interactive.c, it will be simplified slightly in the next
commit.

Phillip Wood 6023c928aa rebase: use OPT_RERERE_AUTOUPDATE()
As we have a macro for this it makes sense to use it. Having
cmd_rebase() and cmd_rebase__interactive() use the same values for
this option will be helpful when we start running interactive rebases
without forking rebase--interactive.

Phillip Wood fc4a6735ee sequencer: always discard index after checkout
As the checkout runs in a separate process our index will be out of date
so it should be discarded. The existing callers are not doing this
consistently so do it here to avoid the callers having to worry about
it.

This fixes some test failures that happen if do_interactive_rebase() is
called without forking rebase--interactive which we will implement
shortly. Running

  git rebase -i master topic

starting on master created empty todo lists because all the commits in
topic were marked as cherry-picks. After topic was checked out in
prepare_branch_to_be_rebased() the working tree contained the contents
from topic but the index contained master and the cache entries were
still valid. This meant that diff_populate_filespec() which loads the
blobs when calculating patch-id's ended up reading the contents for
master from the working tree which actually contained topic.

Johannes Schindelin b7ce24d095 Turn git serve into a test helper
The `git serve` built-in was introduced in ed10cb952d (serve:
introduce git-serve, 2018-03-15) as a backend to serve Git protocol v2,
probably originally intended to be spawned by `git upload-pack`.

However, in the version that the protocol v2 patches made it into core
Git, `git upload-pack` calls the `serve()` function directly instead of
spawning `git serve`; The only reason in life for `git serve` to survive
as a built-in command is to provide a way to test the protocol v2
functionality.

Meaning that it does not even have to be a built-in that is installed
with end-user facing Git installations, but it can be a test helper
instead.

Let's make it so.

Denton Liu d540b70c85 merge: cleanup messages like commit
This change allows git-merge messages to be cleaned up with the
commit.cleanup configuration or --cleanup option, just like how
git-commit does it.

We also give git-pull the option of --cleanup so that it can also take
advantage of this change.

Finally, add testing to ensure that messages are properly cleaned up.
Note that some newlines that were added to the commit message were
removed so that if a file were read via -F, it would be copied
faithfully.
