Earlier we added "-Wformat-security" to developer builds, assuming

Merge branch 'so/cherry-pick-always-allow-m1'

"git cherry-pick -m1" was forbidden when picking a non-merge
commit, even though there _is_ parent number 1 for such a commit.
This was done to avoid mistakes back when "cherry-pick" was about
picking a single commit, but is no longer useful with "cherry-pick"
that can pick a range of commits. Now the "-m$num" option is
allowed when picking any commit, as long as $num names an existing
parent of the commit.

Technically this is a backward incompatible change; hopefully
nobody is relying on the error-checking behaviour.

* so/cherry-pick-always-allow-m1:
t3506: validate '-m 1 -ff' is now accepted for non-merge commits
t3502: validate '-m 1' argument is now accepted for non-merge commits

object-store: use one oid_array per subdirectory for... René Scharfe Sun, 6 Jan 2019 16:45:52 +0000 (17:45 +0100)

object-store: use one oid_array per subdirectory for loose cache

The loose objects cache is filled one subdirectory at a time as needed.
It is stored in an oid_array, which has to be resorted after each add
operation. So when querying a wide range of objects, the partially
filled array needs to be resorted up to 255 times, which takes over 100
times longer than sorting once.

Use one oid_array for each subdirectory. This ensures that entries have
to only be sorted a single time. It also avoids eight binary search
steps for each cache lookup as a small bonus.

The cache is used for collision checks for the log placeholders %h, %t
and %p, and we can see the change speeding them up in a repository with
ca. 100 objects per subdirectory:

$ git count-objects
26733 objects, 68808 kilobytes

worktree: allow to (re)move worktrees with uninitialized submodules

Uninitialized submodules have nothing valueable for us to be worried
about. They are just SHA-1. Let "worktree remove" and "worktree move"
continue in this case so that people can still use multiple worktrees
on repos with optional submodules that are never populated, like
sha1collisiondetection in git.git when checked out by doc-diff script.

Note that for "worktree remove", it is possible that a user
initializes a submodule (*), makes some commits (but not push), then
deinitializes it. At that point, the submodule is unpopulated, but the
precious new commits are still in

$GIT_COMMON_DIR/worktrees/<worktree>/modules/<submodule>

directory and we should not allow removing the worktree or we lose
those commits forever. The new directory check is added to prevent
this.

(*) yes they are screwed anyway by doing this since "git submodule"
would add submodule.* in $GIT_COMMON_DIR/config, which is shared
across multiple worktrees. But it does not mean we let them be
screwed even more.

test-lib: add the '--stress' option to run a test repea... SZEDER Gábor Sat, 5 Jan 2019 01:08:59 +0000 (02:08 +0100)

test-lib: add the '--stress' option to run a test repeatedly under load

Unfortunately, we have a few flaky tests, whose failures tend to be
hard to reproduce. We've found that the best we can do to reproduce
such a failure is to run the test script repeatedly while the machine
is under load, and wait in the hope that the load creates enough
variance in the timing of the test's commands that a failure is
evenually triggered. I have a command to do that, and I noticed that
two other contributors have rolled their own scripts to do the same,
all choosing slightly different approaches.

To help reproduce failures in flaky tests, introduce the '--stress'
option to run a test script repeatedly in multiple parallel jobs until
one of them fails, thereby using the test script itself to increase
the load on the machine.

The number of parallel jobs is determined by, in order of precedence:
the number specified as '--stress=<N>', or the value of the
GIT_TEST_STRESS_LOAD environment variable, or twice the number of
available processors (as reported by the 'getconf' utility), or 8.

Make '--stress' imply '--verbose -x --immediate' to get the most
information about rare failures; there is really no point in spending
all the extra effort to reproduce such a failure, and then not know
which command failed and why.

To prevent the several parallel invocations of the same test from
interfering with each other:

- Include the parallel job's number in the name of the trash
directory and the various output files under 't/test-results/' as
a '.stress-<Nr>' suffix.

- Add the parallel job's number to the port number specified by the
user or to the test number, so even tests involving daemons
listening on a TCP socket can be stressed.

- Redirect each parallel test run's verbose output to
't/test-results/$TEST_NAME.stress-<nr>.out', because dumping the
output of several parallel running tests to the terminal would
create a big ugly mess.

For convenience, print the output of the failed test job at the end,
and rename its trash directory to end with the '.stress-failed'
suffix, so it's easy to find in a predictable path (OTOH, all absolute
paths recorded in the trash directory become invalid; we'll see
whether this causes any issues in practice). If, in an unlikely case,
more than one jobs were to fail nearly at the same time, then print
the output of all failed jobs, and rename the trash directory of only
the last one (i.e. with the highest job number), as it is the trash
directory of the test whose output will be at the bottom of the user's
terminal.

Based on Jeff King's 'stress' script.

test-lib-functions: introduce the 'test_set_port' helpe... SZEDER Gábor Sat, 5 Jan 2019 01:08:58 +0000 (02:08 +0100)

test-lib-functions: introduce the 'test_set_port' helper function

Several test scripts run daemons like 'git-daemon' or Apache, and
communicate with them through TCP sockets. To have unique ports where
these daemons are accessible, the ports are usually the number of the
corresponding test scripts, unless the user overrides them via
environment variables, and thus all those tests and test libs contain
more or less the same bit of one-liner boilerplate code to find out
the port. The last patch in this series will make this a bit more
complicated.

Factor out finding the port for a daemon into the common helper
function 'test_set_port' to avoid repeating ourselves.

Take special care of test scripts with "low" numbers:

- Test numbers below 1024 would result in a port that's only usable
as root, so set their port to '10000 + test-nr' to make sure it
doesn't interfere with other tests in the test suite. This makes
the hardcoded port number in 't0410-partial-clone.sh' unnecessary,
remove it.

- The shell's arithmetic evaluation interprets numbers with leading
zeros as octal values, which means that test number below 1000 and
containing the digits 8 or 9 will trigger an error. Remove all
leading zeros from the test numbers to prevent this.

Note that the 'git p4' tests are unlike the other tests involving
daemons in that:

- 'lib-git-p4.sh' doesn't use the test's number for unique port as
is, but does a bit of additional arithmetic on top [1].

- The port is not overridable via an environment variable.

With this patch even 'git p4' tests will use the test's number as
default port, and it will be overridable via the P4DPORT environment
variable.

[1] Commit fc00233071 (git-p4 tests: refactor and cleanup, 2011-08-22)
introduced that "unusual" unique port computation without
explaining why it was necessary (as opposed to simply using the
test number as is). It seems to be just unnecessary complication,
and in any case that commit came way before the "test nr as unique
port" got "standardized" for other daemons in commits c44132fcf3
(tests: auto-set git-daemon port, 2014-02-10), 3bb486e439 (tests:
auto-set LIB_HTTPD_PORT from test name, 2014-02-10), and

later.

test-lib: consolidate naming of test-results paths

There are two places where we strip off any leading path components
and the '.sh' suffix from the test script's pathname, and there are
four places where we construct the name of the 't/test-results'
directory or the name of various test-specific files in there. The
last patch in this series will add even more.

Factor these out into helper variables to avoid repeating ourselves.

test-lib: parse command line options earlierSZEDER Gábor Sat, 5 Jan 2019 01:08:55 +0000 (02:08 +0100)

test-lib: parse command line options earlier

'test-lib.sh' looks for the presence of certain options like '--tee'
and '--verbose-log', so it can execute the test script again to save
its standard output and error. It looks for '--valgrind' as well, to
set up some Valgrind-specific stuff. These all happen before the
actual option parsing loop, and the conditions looking for these
options look a bit odd, too. They are not completely correct, either,
because in a bogus invocation like './t1234-foo.sh -r --tee' they
recognize '--tee', although it should be handled as the required
argument of the '-r' option. This patch series will add two more
options to look out for early, and, in addition, will have to extract
these options' stuck arguments (i.e. '--opt=arg') as well.

So let's move the option parsing loop and the couple of related
conditions following it earlier in 'test-lib.sh', before the place
where the test script is executed again for '--tee' and its friends.

test-lib: parse options in a for loop to keep $@ intact

'test-lib.sh' looks for the presence of certain options like '--tee'
and '--verbose-log', so it can execute the test script again to save
its standard output and error, and to do so it needs the original
command line options the test was invoked with.

The next patch is about to move the option parsing loop earlier in
'test-lib.sh', but it is implemented using 'shift' in a while loop,
effecively destroying "$@" by the end of the option parsing. Not
good.

As a preparatory step, turn that option parsing loop into a 'for opt
in "$@"' loop to preserve "$@" intact while iterating over the
options, and taking extra care to handle the '-r' option's required
argument (or the lack thereof).

test-lib: extract Bash version check for '-x' tracing

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].

Move this check out from the option parsing loop, so other options can
imply '-x' by setting 'trace=t', without missing this Bash version
check.

config.mak.dev: add -Wall, primarily for -Wformat, to help autoconf users

801fa63a90 ("config.mak.dev: add -Wformat-security", 2018-09-08)
added the "-Wformat-security" to the flags set in config.mak.dev.
In the gcc man page this is documented as:

If -Wformat is specified, also warn about uses of format
functions that represent possible security problems. [...]

The commit did however not add the "-Wformat" flag, but instead
relied on the fact that "-Wall" is set in the Makefile by default
and that "-Wformat" is part of "-Wall".

Unfortunately, those who use config.mak.autogen generated with the
autoconf to configure toolchain do *not* get "-Wall" in their CFLAGS
and the added -Wformat-security had no effect. Worse yet, newer
versions of gcc (gcc 8.2.1 in this particular case) warn about the
lack of "-Wformat" and thus compilation fails only with this option
set.

We could fix it by adding "-Wformat", but in general we do want all
checks included in "-Wall", so let's add it to config.mak.dev to
cover more cases.

map_sha1_file_1() checks if the file it is about to mmap() is empty and

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.

test-lib: translate SIGTERM and SIGHUP to an exitSZEDER Gábor Sun, 30 Dec 2018 19:16:22 +0000 (20:16 +0100)

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.

transport-helper: drop read/write errno checks

Since we use xread() and xwrite() here, EINTR, EAGAIN, and
EWOULDBLOCK retries are already handled for us, and we will
never see these errno values ourselves. We can drop these
conditions entirely, making the code easier to follow.

transport-helper: use xread instead of read

This fix was needed on HPE NonStop NSE and NSX where SSIZE_MAX is less than
BUFFERSIZE resulting in EINVAL. The call to read in transport-helper.c
was the only place outside of wrapper.c where it is used instead of xread.

test-lib: check Bash version for '-x' without using... SZEDER Gábor Thu, 3 Jan 2019 11:43:17 +0000 (12:43 +0100)

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.

completion: treat results of git ls-tree as file pathsChayoung You Tue, 1 Jan 2019 14:05:09 +0000 (23:05 +0900)

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/'.

zsh: complete unquoted paths with spaces correctlyChayoung You Tue, 1 Jan 2019 14:05:08 +0000 (23:05 +0900)

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.

Simplify handling of setup_git_directory_gently() failu... Erin Dahlgren Thu, 27 Dec 2018 23:36:29 +0000 (15:36 -0800)

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().

commit-graph: writing missing parents is a BUGDerrick Stolee Wed, 19 Dec 2018 20:14:07 +0000 (12:14 -0800)

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.

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.

t5570: drop racy testThomas Gummerer Thu, 20 Dec 2018 16:41:50 +0000 (16:41 +0000)

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.
