starting with "ERR". Replace it with a less confusing error message.
Also update the documentation describing the fetch-pack/upload-pack
protocol (pack-protocol.txt) to indicate that "ERR" can be sent in the
place of "ACK" or "NAK". In practice, this has been done for quite some
time by other Git implementations (e.g. JGit sends "want $id not valid")
and by Git itself (since commit bdb31ea: "upload-pack: report "not our

that it does not have. (This is uncommon, but can happen if a repository

receive-pack: drop tmp_objdir_env from run_update_hook
Since 722ff7f87 (receive-pack: quarantine objects until
pre-receive accepts, 2016-10-03), we have to feed the
pre-receive hook the tmp_objdir environment, so that git
programs run from the hook know where to find the objects.
That commit modified run_update_hook() to do the same, but
there it is a noop. By the time we get to the update hooks,
we have already migrated the objects from quarantine, and so
tmp_objdir_env() will always return NULL. We can drop this
useless call.
Note that the ordering here and the lack of support for the
update hook is intentional. The update hook calls are
interspersed with actual ref updates, and we must migrate
the objects before any refs are updated (since otherwise
those refs would appear broken to outside processes). So the
only other options are:
- remain in quarantine for the _first_ ref, but not the
others. This is sufficiently confusing that it can be
rejected outright.
- run all the individual update hooks first, then migrate,
then update all the refs. But this changes the repository
state that the update hooks see (i.e., whether or not
refs from the same push are updated yet or not).
So the functionality is fine and remains unchanged with this
patch; we're just cleaning up a useless and confusing line
of code.

t6500: wait for detached auto gc at the end of the test script
The last test in 't6500-gc', 'background auto gc does not run if
gc.log is present and recent but does if it is old', added in a831c06a2 (gc: ignore old gc.log files, 2017-02-10), may sporadically
trigger an error message from the test harness:
rm: cannot remove 'trash directory.t6500-gc/.git/objects': Directory not empty
The test in question ends with executing an auto gc in the backround,
which occasionally takes so long that it's still running when
'test_done' is about to remove the trash directory. This 'rm -rf
$trash' in the foreground might race with the detached auto gc to
create and delete files and directories, and gc might (re-)create a
path that 'rm' already visited and removed, triggering the above error
message when 'rm' attempts to remove its parent directory.
Commit bb05510e5 (t5510: run auto-gc in the foreground, 2016-05-01)
fixed the same problem in a different test script by simply
disallowing background gc. Unfortunately, what worked there is not
applicable here, because the purpose of this test is to check the
behavior of a detached auto gc.
Make sure that the test doesn't continue before the gc is finished in
the background with a clever bit of shell trickery:
- Open fd 9 in the shell, to be inherited by the background gc
process, because our daemonize() only closes the standard fds 0,
1 and 2.
- Duplicate this fd 9 to stdout.
- Read 'git gc's stdout, and thus fd 9, through a command
substitution. We don't actually care about gc's output, but this
construct has two useful properties:
- This read blocks until stdout or fd 9 are open. While stdout is
closed after the main gc process creates the background process
and exits, fd 9 remains open until the backround process exits.
- The variable assignment from the command substitution gets its
exit status from the command executed within the command
substitution, i.e. a failing main gc process will cause the test
to fail.
Note, that this fd trickery doesn't work on Windows, because due to
MSYS limitations the git process only inherits the standard fds 0, 1
and 2 from the shell. Luckily, it doesn't matter in this case,
because on Windows daemonize() is basically a noop, thus 'git gc
--auto' always runs in the foreground.
And since we can now continue the test reliably after the detached gc
finished, check that there is only a single packfile left at the end,
i.e. that the detached gc actually did what it was supposed to do.
Also add a comment at the end of the test script to warn developers of
future tests about this issue of long running detached gc processes.

unpack-trees: avoid duplicate ODB lookups during checkout
Teach traverse_trees_recursive() to not do redundant ODB
lookups when both directories refer to the same OID.
In operations such as read-tree and checkout, there will
likely be many peer directories that have the same OID when
the differences between the commits are relatively small.
In these cases we can avoid hitting the ODB multiple times
for the same OID.
This patch handles n=2 and n=3 cases and simply copies the
data rather than repeating the fill_tree_descriptor().
================
On the Windows repo (500K trees, 3.1M files, 450MB index),
this reduced the overall time by 0.75 seconds when cycling
between 2 commits with a single file difference.
string-list: use ALLOC_GROW macro when reallocing string_list
Use ALLOC_GROW() macro when reallocing a string_list array
rather than simply increasing it by 32. This is a performance
optimization.
During status on a very large repo and there are many changes,
a significant percentage of the total run time is spent
reallocing the wt_status.changes array.
This change decreases the time in wt_status_collect_changes_worktree()
from 125 seconds to 45 seconds on my very large repository.
This produced a modest gain on my 1M file artificial repo, but
broke even on linux.git.

config: resolve symlinks in conditional include's patterns
$GIT_DIR returned by get_git_dir() is normalized, with all symlinks
resolved (see setup_work_tree function). In order to match paths (or
patterns) against $GIT_DIR char-by-char, they have to be normalized
too. There is a note in config.txt about this, that the user need to
resolve symlinks by themselves if needed.
The problem is, we allow certain path expansion, '~/' and './', for
convenience and can't ask the user to resolve symlinks in these
expansions. Make sure the expanded paths have all symlinks resolved.
PS. The strbuf_realpath(&text, get_git_dir(), 1) is still needed because

files-backend: replace submodule_allowed check in files_downcast()
files-backend.c is unlearning submodules. Instead of having a specific
check for submodules to see what operation is allowed, files backend
now takes a set of flags at init. Each operation will check if the
required flags is present before performing.
For now we have four flags: read, write and odb access. Main ref store
has all flags, obviously, while submodule stores are read-only and have
access to odb (*).
The "main" flag stays because many functions in the backend calls
frontend ones without a ref store, so these functions always target the
main ref store. Ideally the flag should be gone after ref-store-aware
api is in place and used by backends.
(*) Submodule code needs for_each_ref. Try take REF_STORE_ODB flag
out. At least t3404 would fail. The "have access to odb" in submodule is
a bit hacky since we don't know from he whether add_submodule_odb() has

The left and right base directories were pointed to the buf field of

A contrived test case shows the problem where a file with a long enough
name to force the strbuf to grow is up-to-date (hence the code path is
used where the work tree's version of the file is reused), and then a
file that is not up-to-date needs to be written (hence the code path is
used where checkout_entry() uses the previously recorded base_dir that
is invalid by now).
Let's just copy the base_dir strings for use with checkout_entry(),
never touch them until the end, and release them then. This is an easily

authentication", 2016-01-26), if the user specified an invalid HTTP
proxy option in the configuration, then the option parsing silently
fails and NULL will be passed to curl as a proxy. This forces curl to
fall back to detecting the proxy configuration from the environment,
causing the http.proxy option ignoring.
Fix this issue by checking the proxy option parsing result. If parsing
failed then print an error message and die. Such behaviour allows the
user to quickly figure the proxy misconfiguration and correct it.

http: honor empty http.proxy option to bypass proxy
Curl distinguishes between an empty proxy address and a NULL proxy
address. In the first case it completely disables proxy usage, but if
the proxy address option is NULL then curl attempts to determine the
proxy address from the http_proxy environment variable.
According to the documentation, if the http.proxy option is set to an
empty string, git should bypass proxy and connect to the server
directly:
export http_proxy=http://network-proxy/
cd ~/foobar-project
git config remote.origin.proxy ""
git fetch
Previously, proxy host was configured by one line:
Commit 372370f167 ("http: use credential API to handle proxy
authentication", 2016-01-26) parses the proxy option, then extracts the
proxy host address and updates the curl configuration, making the
previous call a noop:
But if the proxy option is empty then the proxy host field becomes NULL.
This forces curl to fall back to detecting the proxy configuration from
the environment, causing the http.proxy option to not work anymore.
Fix this issue by explicitly handling http.proxy being set the empty
string. This also makes the code a bit more clear and should help us
avoid such regressions in the future.

An empty line should stop any pending in-body headers, and start the
actual body parsing.
This also modifies the original test for the in-body headers to actually
have a real commit body that starts with spaces, and changes the test to
check that the long line matches _exactly_, and doesn't get extra data
from the body.

push: propagate remote and refspec with --recurse-submodules
Teach "push --recurse-submodules" to propagate, if given a name as remote, the
provided remote and refspec recursively to the pushes performed in the
submodules. The push will therefore only succeed if all submodules have a
remote with such a name configured.
Note that "push --recurse-submodules" with a path or URL as remote will not
propagate the remote or refspec and instead use the default remote and refspec
configured in the submodule, preserving the current behavior.

"git tag/branch/for-each-ref" family of commands long allowed to
filter the refs by "--contains X" (show only the refs that are
descendants of X), "--merged X" (show only the refs that are

diff: submodule inline diff to initialize env array.
David reported:

This happens, because we do not properly initialize the environment
in which the diff is run in the submodule. That means we inherit the
environment from the main process, which sets environment variables.
(Apparently we do set environment variables which we do not set
when not in a submodules, i.e. the .git directory is linked)
This commit, just like fd47ae6a5b (diff: teach diff to display
submodule difference with an inline diff, 2016-08-31) introduces bad
test code (i.e. hard coded hash values), which will be cleanup up in
a later patch.
