Users of the parse_options_concat() API function need to allocate
extra slots in advance and fill them with OPT_END() when they want
to decide the set of supported options dynamically, which makes the
code error-prone and hard to read. This has been corrected by tweaking
the API to allocate and return a new copy of "struct option" array.

On OSX `wc` prefixes the output of numbers with whitespace, such
that the `commit_count` would be "SP <NUMBER>". When using that in
git submodule update --init --depth=$commit_count
the depth would be empty and the number is interpreted as the
pathspec. Fix this by not using `wc` and rather instruct rev-list
to count.
Another way to fix this is to remove the `=` sign after the
`--depth` argument as then we are allowed to have more than just one
whitespace between `--depth` and the actual number. Prefer the
solution of rev-list counting as that is expected to be slightly
faster and more self-contained within Git.

Avoid waking up the readers for unnecessary context switches for

It is unlikely any HTTP/1.x server would want to read a CGI

Instead, I'd expect HTTP servers want to minimize syscall and

submodule--helper: use parallel processor correctly
When developing another patch series I had a temporary state in
which git-clone would segfault, when the call was prepared in
prepare_to_clone_next_submodule. This lead to the call failing,
i.e. in `update_clone_task_finished` the task was scheduled to be
tried again. The second call to prepare_to_clone_next_submodule
would return 0, as the segfaulted clone did create the .git file
already, such that was not considered to need to be cloned again. I
was seeing the "BUG: ce was a submodule before?\n" message, which
was the correct behavior at the time as my local code was
buggy. When trying to debug this failure, I tried to use printing
messages into the strbuf that is passed around, but these messages
were never printed as the die(..) doesn't flush the `err` strbuf.
When implementing the die() in 665b35ecc (2016-06-09, "submodule--helper:
initial clone learns retry logic"), I considered this condition to be
a severe condition, which should lead to an immediate abort as we do not
trust ourselves any more. However the queued messages in `err` are valuable
so let's not toss them out by immediately dying, but a graceful return.
Another thing to note: The error message itself was misleading. A return
value of 0 doesn't indicate the passed in `ce` is not a submodule any more,
but just that we do not consider cloning it any more.

commit-slab.h: avoid duplicated global static variables
The gigantic define_commit_slab() macro repeats the definition of a
static variable that occurs earlier in the macro text. The purpose of
the repeated definition at the end of the macro is that it takes the
semicolon that occurs where the macro is used.
We cannot just remove the first definition of the variable because it
is referenced elsewhere in the macro text, and defining the macro later
would produce undefined identifier errors. We cannot have a "forward"
declaration, either. (This works only with "extern" global variables.)
The solution is to use a declaration of a struct that is already defined
earlier. This language construct can serve the same purpose as the
duplicated static variable definition, but without the confusion.

parameter.
In nedmalloc()'s reimplementation of strdup(), Postel's Law is heeded
and NULL parameters are handled gracefully. GCC 6 complains about that
now because it thinks that NULL cannot be passed to strdup() anyway.
Because the callers in this project of strdup() must be prepared to
call any implementation of strdup() supplied by the platform, so it
is pointless to pretend that it is OK to call it with NULL.
Remove the conditional based on NULL-ness of the input; this
squelches the warning. Check the return value of malloc() instead

If the trace code cannot open a specified file, or does not
understand the contents of the GIT_TRACE variable, it falls
back to printing trace output to stderr.
This is an attempt to be helpful, but in practice it just
ends up annoying. The user was trying to get the output to
go somewhere else, so spewing it to stderr does not really
accomplish that. And as it's intended for debugging, they
can presumably re-run the command with their error
corrected.
So instead of falling back, this patch disables bogus trace
keys for the rest of the program, just as we do for write
errors. We can drop the "Defaulting to..." part of the error
message entirely; after seeing "cannot open '/foo'", the
user can assume that tracing is skipped.

This function has no callers, and is not likely to gain any
because it's confusing to use.
It unconditionally complains to stderr, but _doesn't_ die.
Yet any caller which wants a "gentle" write would generally
want to suppress the error message, because presumably
they're going to write a better one, and/or try the
operation again.
And the check_pipe() call leads to confusing behaviors. It
means we die for EPIPE, but not for other errors, which is
confusing and pointless.
On top of all that, it has unusual error return semantics,
which makes it easy for callers to get it wrong.

If we get a write error writing to a trace descriptor, the

You don't really need to see:
warning: unable to write trace for GIT_TRACE_PACKET: Bad file descriptor
hundreds of times. We could fallback to tracing to stderr,
as we do in the error code-path for open(), but there's not
much point. If the user fed us a bogus descriptor, they're
probably better off fixing their invocation. And if they
didn't, and we saw a transient error (e.g., ENOSPC writing
to a file), it probably doesn't help anybody to have half of
the trace in a file, and half on stderr.

trace: correct variable name in write() error message
Our error message for write() always mentions GIT_TRACE,
even though we may be writing for a different variable
entirely. It's also not quite accurate to say "fd given by
GIT_TRACE environment variable", as we may hit this error
based on a filename the user put in the variable (we do
complain and switch to stderr if the file cannot be opened,
but it's still possible to hit a write() error on the
descriptor later).
So let's fix those things, and switch to our more usual
"unable to do X: Y" format for the error.

The error messages for the trace code are often multi-line;
the first line gets a nice "warning:", but the rest are
left-aligned. Let's give them an indentation to make sure
they stand out as a unit.
While we're here, let's also downcase the first letter of
each error (our usual style), and break up a long line of
advice (since we're already using multiple lines, one more
doesn't hurt).
We also replace "What does 'foo' for GIT_TRACE mean?". While
cute, it's probably a good idea to give more context, and
follow our usual styles. So it's now "unknown trace value
for 'GIT_TRACE': foo".

Right now we just fprintf() straight to stderr, which can
make the output hard to distinguish. It would be helpful to
give it one of our usual prefixes like "error:", "warning:",
etc.
It doesn't make sense to use error() here, as the trace code
is "optional" debugging code. If something goes wrong, we
should warn the user, but saying "error" implies the actual
git operation had a problem. So warning() is the only sane
choice.
Note that this does end up calling warn_routine() to do the
formatting. This is probably a good thing, since they are
clearly trying to hook messages before they make it to
stderr. However, it also means that in theory somebody who
tries to trace from their warn_routine() could cause a loop.
This seems rather unlikely in practice (we've never even
overridden the default warn_builtin routine before, and
recent discussions to do so would just install a noop
routine).

1. it checks for EPIPE and converts it into a signal death
2. it prints a message to stderr on error
The first thing does not help us, and actively hurts.
Generally we would simply die from SIGPIPE in this case,
unless somebody has taken the time to ignore SIGPIPE for the
whole process. And if they _did_ do that, it seems rather
silly for the trace code, which otherwise takes pains to
continue even in the face of errors (e.g., by not using
write_or_die!), to take down the whole process for one
specific type of error.
Nor does the second thing help us; it just makes it harder
to write our error message, because we have to feed bits of
it as an argument to write_or_whine_pipe(). Translators
never get to see the full message, and it's hard for us to
customize it.
Let's switch to just using write_in_full() and writing our
own error string. For now, the error is identical to what
write_or_whine_pipe() would say, but now that it's more
under our control, we can improve it in future patches.

t7063: work around FreeBSD's lazy mtime update feature
Let's start with the commit message of [1] from freebsd.git [2]
Sync timestamp changes for inodes of special files to disk as late
as possible (when the inode is reclaimed). Temporarily only do
this if option UFS_LAZYMOD configured and softupdates aren't
enabled. UFS_LAZYMOD is intentionally left out of
/sys/conf/options.
This is mainly to avoid almost useless disk i/o on battery powered
machines. It's silly to write to disk (on the next sync or when
the inode becomes inactive) just because someone hit a key or
something wrote to the screen or /dev/null.
PR: 5577 [3]
The short version of that, in the context of t7063, is that when a
directory is updated, its mtime may be updated later, not
immediately. This can be shown with a simple command sequence
One would expect that the date shown in `ls` would be one second from
`date`, but it's 10 seconds later. If we put another `ls -lTd .` in
front of `sleep 10`, then the date of the last `ls` comes as
expected. The first `ls` somehow forces mtime to be updated.
t7063 is really sensitive to directory mtime. When mtime is too "new",
git code suspects racy timestamps and will not trigger the shortcut in
untracked cache, in t7063.24 and eventually be detected in t7063.27
We have two options thanks to this special FreeBSD feature:
1) Stop supporting untracked cache on FreeBSD. Skip t7063 entirely
when running on FreeBSD
2) Work around this problem (using the same 'ls' trick) and continue
to support untracked cache on FreeBSD
I initially wanted to go with 1) because I didn't know the exact
nature of this feature and feared that it would make untracked cache
work unreliably, using the cached version when it should not.
Since the behavior of this thing is clearer now. The picture is not
that bad. If this indeed happens often, untracked cache would assume
racy condition more often and _fall back_ to non-untracked cache code
paths. Which means it may be less effective, but it will not show
wrong things.
This patch goes with option 2.
PS. For those who want to look further in FreeBSD source code, this
flag is now called IN_LAZYMOD. I can see it's effective in ext2 and
ufs. zfs is not affected.
Gerrit has a "superproject subscription" feature[1], that triggers a
commit in a superproject that is subscribed to its submodules.
Conceptually this Gerrit feature can be done on the client side with
Git via (except for raciness, error handling etc):
while [ true ]; do
git -C <superproject> submodule update --remote --force
git -C <superproject> commit -a -m "Update submodules"
git -C <superproject> push
done
for each branch in the superproject. To ease the configuration in Gerrit
a special value of "." has been introduced for the submodule.<name>.branch
to mean the same branch as the superproject[2], such that you can create a
new branch on both superproject and the submodule and this feature
continues to work on that new branch.
Now we find projects in the wild with such a .gitmodules file.
The .gitmodules used in these Gerrit projects do not conform
to Gits understanding of how .gitmodules should look like.
This teaches Git to deal gracefully with this syntax as well.
The redefinition of "." does no harm to existing projects unaware of
this change, as "." is an invalid branch name in Git, so we do not
expect such projects to exist.

There is an optimization used in "git diff $treeA $treeB" to borrow
