eebfe40962 t5562: avoid non-portable "export FOO=bar" construct
Commit 6c213e863a ("http-backend: respect CONTENT_LENGTH for
receive-pack", 2018-07-27) adds a test which uses the non-portable
export construct. Replace it with "FOO=bar && export FOO" instead.

6c213e863a http-backend: respect CONTENT_LENGTH for receive-pack
Push passes to another commands, as described in
https://public-inbox.org/git/20171129032214.GB32345@sigill.intra.peff.net/

As it gets complicated to correctly track the data length, instead transfer
the data through parent process and cut the pipe as the specified length is
reached. Do it only when CONTENT_LENGTH is set, otherwise pass the input
directly to the forked commands.

Add tests for cases:

* CONTENT_LENGTH is set, script's stdin has more data, with all combinations
  of variations: fetch or push, plain or compressed body, correct or truncated
  input.

* CONTENT_LENGTH is specified to a value which does not fit into ssize_t.

6c301adb0a fetch: do not pass ref-prefixes for fetch by exact SHA1
When v2.18.0-rc0~10^2~1 (refspec: consolidate ref-prefix generation
logic, 2018-05-16) factored out the ref-prefix generation code for
reuse, it left out the 'if (!item->exact_sha1)' test in the original
ref-prefix generation code. As a result, fetches by SHA-1 generate
ref-prefixes as though the SHA-1 being fetched were an abbreviated ref
name:

 $ GIT_TRACE_PACKET=1 bin-wrappers/git -c protocol.version=2 \
	fetch origin 12039e008f
[...]
 packet:        fetch> ref-prefix 12039e008f
 packet:        fetch> ref-prefix refs/12039e008f9a4e3394f3f94f8ea897785cb09448
 packet:        fetch> ref-prefix refs/tags/12039e008f9a4e3394f3f94f8ea897785cb09448
 packet:        fetch> ref-prefix refs/heads/12039e008f9a4e3394f3f94f8ea897785cb09448
 packet:        fetch> ref-prefix refs/remotes/12039e008f9a4e3394f3f94f8ea897785cb09448
 packet:        fetch> ref-prefix refs/remotes/12039e008f9a4e3394f3f94f8ea897785cb09448/HEAD
 packet:        fetch> 0000

If there is another ref name on the command line or the object being
fetched is already available locally, then that's mostly harmless.
But otherwise, we error out with

 fatal: no matching remote head

since the server did not send any refs we are interested in.  Filter
out the exact_sha1 refspecs to avoid this.

This patch adds a test to check this behavior that notices another
behavior difference between protocol v0 and v2 in the process.  Add a
NEEDSWORK comment to clear it up.

5971b0836e sequencer: ensure labels that are object IDs are rewritten
When writing the todo script for --rebase-merges, we try to find a label
for certain commits.  If the label ends up being a valid object ID, such
as when we merge a detached commit, we want to rewrite it so it is no
longer a valid object ID.

However, the code path that does this checks for its length to be
equivalent to GIT_SHA1_RAWSZ, which isn't correct, since what we are
reading is a hex object ID.  Instead, check for the length being
equivalent to that of a hex object ID.  Use the_hash_algo so this code
works regardless of the hash size.

5340d47107 t990X: use '.git/objects' as 'deep inside .git' path
Tests t9902-completion.sh and t9903-bash-prompt.sh each have tests
that check what happens when we are "in the '.git' directory" and
when we are "deep inside the '.git' directory".

To test the case when we are "deep inside the '.git' directory" the
test scripts used to perform a `cd .git/refs/heads`.

As there are plans to implement other ref storage systems, let's
use '.git/objects' instead of '.git/refs/heads' as the "deep inside
the '.git' directory" path.

This makes it clear to readers that these tests do not depend on
which ref backend is used.

The internals of the loose refs backend are still tested in
t1400-update-ref.sh.

123f631761 git-p4: add unshelve command
This can be used to "unshelve" a shelved P4 commit into
a git commit.

For example:

  $ git p4 unshelve 12345

The resulting commit ends up in the branch:
   refs/remotes/p4/unshelved/12345

If that branch already exists, it is renamed - for example
the above branch would be saved as p4/unshelved/12345.1.

git-p4 checks that the shelved changelist is based on files
which are at the same Perforce revision as the origin branch
being used for the unshelve (HEAD by default). If they are not,
it will refuse to unshelve. This is to ensure that the unshelved
change does not contain other changes mixed-in.

The reference branch can be changed manually with the "--origin"
option.

The change adds a new Unshelve command class. This just runs the
existing P4Sync code tweaked to handle a shelved changelist.

cbc5cf7ce5 t: make many tests depend less on the refs being files
Many tests are very focused on the file system representation of the
loose and packed refs code. As there are plans to implement other
ref storage systems, let's migrate these tests to a form that test
the intent of the refs storage system instead of it internals.

This will make clear to readers that these tests do not depend on
which ref backend is used.

The internals of the loose refs backend are still tested in
t1400-update-ref.sh, whereas the tests changed in this patch focus
on testing other aspects.

This patch just takes care of many low hanging fruits. It does not
try to completely solves the issue.

71cdbb3d4a Merge branch 'tb/test-apfs-utf8-normalization'
A test to see if the filesystem normalizes UTF-8 filename has been
updated to check what we need to know in a more direct way, i.e. a
path created in NFC form can be accessed with NFD form (or vice
versa) to cope with APFS as well as HFS.

* tb/test-apfs-utf8-normalization:
  test: correct detection of UTF8_NFD_TO_NFC for APFS

"git pack-objects" needs to allocate tons of "struct object_entry"
while doing its work, and shrinking its size helps the performance
quite a bit.

c67de747f4 Merge branch 'en/rename-directory-detection-reboot'
Rename detection logic in "diff" family that is used in "merge" has
learned to guess when all of x/a, x/b and x/c have moved to z/a,
z/b and z/c, it is likely that x/d added in the meantime would also
want to move to z/d by taking the hint that the entire directory
'x' moved to 'z'.  A bug causing dirty files involved in a rename
to be overwritten during merge has also been fixed as part of this
work.  Incidentally, this also avoids updating a file in the
working tree after a (non-trivial) merge whose result matches what
our side originally had.

* en/rename-directory-detection-reboot: (36 commits)
  merge-recursive: fix check for skipability of working tree updates
  merge-recursive: make "Auto-merging" comment show for other merges
  merge-recursive: fix remainder of was_dirty() to use original index
  merge-recursive: fix was_tracked() to quit lying with some renamed paths
  t6046: testcases checking whether updates can be skipped in a merge
  merge-recursive: avoid triggering add_cacheinfo error with dirty mod
  merge-recursive: move more is_dirty handling to merge_content
  merge-recursive: improve add_cacheinfo error handling
  merge-recursive: avoid spurious rename/rename conflict from dir renames
  directory rename detection: new testcases showcasing a pair of bugs
  merge-recursive: fix remaining directory rename + dirty overwrite cases
  merge-recursive: fix overwriting dirty files involved in renames
  merge-recursive: avoid clobbering untracked files with directory renames
  merge-recursive: apply necessary modifications for directory renames
  merge-recursive: when comparing files, don't include trees
  merge-recursive: check for file level conflicts then get new name
  merge-recursive: add computation of collisions due to dir rename & merging
  merge-recursive: check for directory level conflicts
  merge-recursive: add get_directory_renames()

The functionality of "$GIT_DIR/info/grafts" has been superseded by
the "refs/replace/" mechanism for some time now, but the internal

  Remove obsolete script to convert grafts to replace refs
  technical/shallow: describe why shallow cannot use replace refs
  technical/shallow: stop referring to grafts

"git gc" in a large repository takes a lot of time as it considers
to repack all objects into one pack by default.  The command has
been taught to pretend as if the largest existing packfile is
marked with ".keep" so that it is left untouched while objects in
other packs and loose ones are repacked.

  pack-objects: show some progress when counting kept objects
  gc --auto: exclude base pack if not enough mem to "repack -ad"
