3c78e97d5d Revert "t/lib-git-daemon: record daemon log"
This reverts commit 314a73d658 (t/lib-git-daemon: record daemon log,
2018-01-25), which let tests use the output of git-daemon.

The previous commit removed the last user of deamon.log in the tests,
there's no good way to make checking for output in the log
race-proof.  Revert this commit as well, to make sure others are not
tempted to use daemon.log in tests in the future, which would lead to
racy tests.

The original commit had one change that still makes sense, namely
switching read/echo for "read -r" and "printf", which relays the data
more faithfully.  Don't revert that piece here, as it is still a
useful change.

d45cec4bea test-lib: translate SIGTERM and SIGHUP to an exit
Right now if a test script receives SIGTERM or SIGHUP (e.g., because a
test was hanging and the user 'kill'-ed it or simply closed the
terminal window the test was running in), the shell exits immediately.
This can be annoying if the test script did any global setup, like
starting apache or git-daemon, as it will not have an opportunity to
clean up after itself. A subsequent run of the test won't be able to
start its own daemon, and will either fail or skip the tests.

Instead, let's trap SIGTERM and SIGHUP as well to make sure we do a
clean shutdown, and just chain it to a normal exit (which will trigger
any cleanup).

This patch follows suit of da706545f7 (t: translate SIGINT to an exit,
2015-03-13), and even stole its commit message as well.

5826b7b595 test-lib: check Bash version for '-x' without using shell arrays
One of our test scripts, 't1510-repo-setup.sh' [1], still can't be
reliably run with '-x' tracing enabled, unless it's executed with a
Bash version supporting BASH_XTRACEFD (since v4.1).  We have a lengthy
condition to check the version of the shell running the test script,
and disable tracing if it's not executed with a suitable Bash version
[2].

This condition uses non-portable shell array accesses to easily get
Bash's major and minor version number.  This didn't seem to be
problematic, because the simple commands expanding those array
accesses are only executed when the test script is actually run with
Bash.  When run with Dash, the only shell I have at hand that doesn't
support shell arrays, there are no issues, as it apparently skips
right over the non-executed simple commands without noticing the
non-supported constructs.

Alas, it has been reported that NetBSD's /bin/sh does complain about
them:

  ./test-lib.sh: 327: Syntax error: Bad substitution

where line 327 contains the first ${BASH_VERSINFO[0]} array access.

To my understanding both shells are right and conform to POSIX,
because the standard allows both behaviors by stating the following
under '2.8.1 Consequences of Shell Errors' [3]:

  "An expansion error is one that occurs when the shell expansions
  define in wordexp are carried out (for example, "${x!y}", because
  '!' is not a valid operator); an implementation may treat these as
  syntax errors if it is able to detect them during tokenization,
  rather than during expansion."

Avoid this issue with NetBSD's /bin/sh (and potentially with other,
less common shells) by hiding the shell array syntax behind 'eval'
that is only executed with Bash.

6d54f528c7 completion: treat results of git ls-tree as file paths
Let's say there are files named 'foo bar.txt', and 'abc def/test.txt' in
repository. When following commands trigger a completion:

    git show HEAD:fo<Tab>
    git show HEAD:ab<Tab>

The completion results in bash/zsh:

    git show HEAD:foo bar.txt
    git show HEAD:abc def/

Where the both of them have an unescaped space in paths, so they'll be
misread by git. All entries of git ls-tree either a filename or a
directory, so __gitcomp_file() is proper rather than __gitcomp_nl().

Note the commit f12785a3, which handles quoted paths properly. Like this
case, we should dequote $cur_ for ?*:* case. For example, let's say
there is untracked directory 'abc deg', then trigger a completion:

    git show HEAD:abc\ de<Tab>
    git show HEAD:'abc de<Tab>
    git show HEAD:"abc de<Tab>

should uniquely complete 'abc def', but bash completes 'abc def' and
'abc deg' instead. In zsh, triggering a completion:

    git show HEAD:abc\ def/<Tab>

should complete 'test.txt', but nothing comes. The both problems will be
resolved by dequoting paths.

__git_complete_revlist_file() passes arguments to __gitcomp_nl() where
the first one is a list something like:

    abc def/Z
    foo bar.txt Z

where Z is the mark of the EOL.

- The trailing space of blob in __git ls-tree | sed.
  It makes the completion results become:

      git show HEAD:foo\ bar.txt\ <CURSOR>

  So git will try to find a file named 'foo bar.txt ' instead.

- The trailing slash of tree in __git ls-tree | sed.
  It makes the completion results on zsh become:

      git show HEAD:abc\ def/ <CURSOR>

  So that the last space on command like should be removed on zsh to
  complete filenames under 'abc def/'.

7a478b36aa zsh: complete unquoted paths with spaces correctly
The following is the description of -Q flag of zsh compadd [1]:

    This flag instructs the completion code not to quote any
    metacharacters in the words when inserting them into the command
    line.

Let's say there is a file named 'foo bar.txt' in repository, but it's
not yet added to the repository. Then the following command triggers a
completion:

    git add fo<Tab>
    git add 'fo<Tab>
    git add "fo<Tab>

The completion results in bash:

    git add foo\ bar.txt
    git add 'foo bar.txt'
    git add "foo bar.txt"

While them in zsh:

    git add foo bar.txt
    git add 'foo bar.txt'
    git add "foo bar.txt"

The first one, where the pathname is not enclosed in quotes, should
escape the space with a backslash, just like bash completion does.
Otherwise, this leads git to think there are two files; foo, and
bar.txt.

The main cause of this behavior is __gitcomp_file_direct(). The both
implementions of bash and zsh are called with an argument 'foo bar.txt',
but only bash adds a backslash before a space on command line.

07098b81a4 Simplify handling of setup_git_directory_gently() failure cases.
setup_git_directory_gently() expects two types of failures to
discover a git directory (e.g. .git/):

  - GIT_DIR_HIT_CEILING: could not find a git directory in any
	parent directories of the cwd.
  - GIT_DIR_HIT_MOUNT_POINT: could not find a git directory in
	any parent directories up to the mount point of the cwd.

Both cases are handled in a similar way, but there are misleading
and unimportant differences. In both cases, setup_git_directory_gently()
should:

  - Die if we are not in a git repository. Otherwise:
  - Set nongit_ok = 1, indicating that we are not in a git repository
	but this is ok.
  - Call strbuf_release() on any non-static struct strbufs that we
	allocated.

Before this change are two misleading additional behaviors:

  - GIT_DIR_HIT_CEILING: setup_nongit() changes to the cwd for no
	apparent reason. We never had the chance to change directories
	up to this point so chdir(current cwd) is pointless.
  - GIT_DIR_HIT_MOUNT_POINT: strbuf_release() frees the buffer
	of a static struct strbuf (cwd). This is unnecessary because the
	struct is static so its buffer is always reachable. This is also
	misleading because nowhere else in the function is this buffer
	released.

This change eliminates these two misleading additional behaviors and
deletes setup_nogit() because the code is clearer without it. The
result is that we can see clearly that GIT_DIR_HIT_CEILING and
GIT_DIR_HIT_MOUNT_POINT lead to the same behavior (ignoring the
different help messages).

During review, this change was amended to additionally include:

  - Neither GIT_DIR_HIT_CEILING nor GIT_DIR_HIT_MOUNT_POINT may
	return early from setup_git_directory_gently() before the
	GIT_PREFIX environment variable is reset. Change both cases to
	break instead of return. See GIT_PREFIX below for more details.

  - GIT_DIR_NONE: setup_git_directory_gently_1() never returns this
	value, but if it ever did, setup_git_directory_gently() would
	incorrectly record that it had found a repository. Explicitly
	BUG on this case because it is underspecified.

  - GIT_PREFIX: this environment variable must always match the
	value of startup_info->prefix and the prefix returned from
	setup_git_directory_gently(). Make how we handle this slightly
	more repetitive but also more clear.

  - setup_git_env() and repo_set_hash_algo(): Add comments showing
	that only GIT_DIR_EXPLICIT, GIT_DIR_DISCOVERED, and GIT_DIR_BARE
	will cause setup_git_directory_gently() to call these setup
	functions. This was obvious (but partly incorrect) before this
	change when GIT_DIR_HIT_MOUNT_POINT returned early from
	setup_git_directory_gently().

cce99cd8c6 commit-graph: writing missing parents is a BUG
When writing a commit-graph, we write GRAPH_MISSING_PARENT if the
parent's object id does not appear in the list of commits to be
written into the commit-graph. This was done as the initial design
allowed commits to have missing parents, but the final version
requires the commit-graph to be closed under reachability. Thus,
this GRAPH_MISSING_PARENT value should never be written.

However, there are reasons why it could be written! These range
from a bug in the reachable-closure code to a memory error causing
the binary search into the list of object ids to fail. In either
case, we should fail fast and avoid writing the commit-graph file
with bad data.

Remove the GRAPH_MISSING_PARENT constant in favor of the constant
GRAPH_EDGE_LAST_MASK, which has the same value.

2d103c31c2 pack-protocol.txt: accept error packets in any context
In the Git pack protocol definition, an error packet may appear only in
a certain context. However, servers can face a runtime error (e.g. I/O
error) at an arbitrary timing. This patch changes the protocol to allow
an error packet to be sent instead of any packet.

Without this protocol spec change, when a server cannot process a
request, there's no way to tell that to a client. Since the server
cannot produce a valid response, it would be forced to cut a connection
without telling why. With this protocol spec change, the server can be
more gentle in this situation. An old client may see these error packets
as an unexpected packet, but this is not worse than having an unexpected
EOF.

Following this protocol spec change, the error packet handling code is
moved to pkt-line.c. Implementation wise, this implementation uses
pkt-line to communicate with a subprocess. Since this is not a part of
Git protocol, it's possible that a packet that is not supposed to be an
error packet is mistakenly parsed as an error packet. This error packet
handling is enabled only for the Git pack protocol parsing code
considering this.

strncat() has the same quadratic behavior as strcat() and is
difficult-to-read and bug-prone.  While it hasn't yet been a
problem in git iself, strncat() found it's way into 'master'
of cgit and caused segfaults on my system.

b4583d5595 doc/config: do a better job of introducing 'worktree.guessRemote'
The documentation for this option jumps right in with "With `add`",
without explaining that `add` is a sub-command of "git worktree".
Together with rather odd grammatical structure of the remainder of the
sentence, the description can be difficult for newcomers to understand.
Clarify by improving the grammar and mentioning "git worktree add"
explicitly.

f24eaf4a21 t5570: drop racy test
t5570 being racy has been reported twice separately on the mailing
list [*1*, *2*].

To make the test race proof, we'd either have to introduce another
fifo the test snippet is waiting on, or somehow convincing "cat" to
flush (and let us know when it has).  Which really implies killing the
daemon, and wait()ing on cat to process the EOF and exit.  And that
makes the tests a lot more expensive if we have to start the daemon
for each snippet.

As this is a test for a relatively minor fix (according to the author)
in 19136be3f8 ("daemon: fix off-by-one in logging extended
attributes", 2018-01-24), drop it to avoid this racyness.  It doesn't
seem worth making the test code much more complex, or slowing down all
tests just to keep this one.

ec0c5798ee revision: use commit graph in get_reference()
When fetching into a repository, a connectivity check is first made by
check_exist_and_connected() in builtin/fetch.c that runs:

  git rev-list --objects --stdin --not --all --quiet <(list of objects)

If the client repository has many refs, this command can be slow,
regardless of the nature of the server repository or what is being
fetched. A profiler reveals that most of the time is spent in
setup_revisions() (approx. 60/63), and of the time spent in
setup_revisions(), most of it is spent in parse_object() (approx.
49/60). This is because setup_revisions() parses the target of every ref
(from "--all"), and parse_object() reads the buffer of the object.

Reading the buffer is unnecessary if the repository has a commit graph
and if the ref points to a commit (which is typically the case). This
patch uses the commit graph wherever possible; on my computer, when I
run the above command with a list of 1 object on a many-ref repository,
I get a speedup from 1.8s to 1.0s.

Another way to accomplish this effect would be to modify parse_object()
to use the commit graph if possible; however, I did not want to change
parse_object()'s current behavior of always checking the object
signature of the returned object.

33311fa1ad ref-filter: add deltabase option
Add new formatting option: deltabase.
If the object is stored as a delta on-disk, this expands
to the 40-hex sha1 of the delta base object.
Otherwise, expands to the null sha1 (40 zeroes).
We have same option in cat-file command.
Hopefully, in the end I will remove formatting code from
cat-file and reuse formatting parts from ref-filter.

ff509c585e t/helper/test-repository: celebrate independence from the_repository
dade47c06c (commit-graph: add repo arg to graph readers, 2018-07-11)
brought more independence from the_repository to the commit graph, however
it was not completely independent of the_repository, as the previous
patches show.

To ensure we're not accessing the_repository by accident, we'd ideally
assign NULL to the_repository to trigger a segfault on access.

We currently have a temporary hack in cache.h, which relies on
the_hash_algo (which is a short form of the_repository->hash_algo) to
be set, so we cannot do that. The next best thing is to set all fields of
the_repository to 0, so any accidental access is more likely to be found.

In push_submodule(), because we do not actually need access to objects
in the submodule, do not invoke add_submodule_odb().
(for_each_remote_ref_submodule() does not require access to those
objects, and the actual push is done by spawning another process,
which handles object access by itself.)

This code of push_submodule() is exercised in t5531 and continues
to work, showing that the submodule odbc is not needed.

957da75802 stripspace: allow -s/-c outside git repository
v2.11.0-rc3~3^2~1 (stripspace: respect repository config, 2016-11-21)
improved stripspace --strip-comments / --comentlines by teaching them
to read repository config, but it went a little too far: when running
stripspace outside any repository, the result is

	$ git stripspace --strip-comments <test-input
	fatal: not a git repository (or any parent up to mount point /tmp)

That makes experimenting with the stripspace command unnecessarily
fussy.  Fix it by discovering the git directory gently, as intended
all along.

b62eb1d2f4 git-status.txt: render tables correctly under Asciidoctor
Asciidoctor removes the indentation of each line in these tables, so the
last lines of each table have a completely broken alignment.

Similar to 379805051d ("Documentation: render revisions correctly under
Asciidoctor", 2018-05-06), use an explicit literal block to indicate
that we want to keep the leading whitespace in the tables.

Because this gives us some extra indentation, we can remove the one that
we have been carrying explicitly. That is, drop the first four spaces of
indentation on each line. With Asciidoc (8.6.10), this results in
identical rendering before and after this commit, both for git-status.1
and git-status.html.
