The inferred size is passed first to st_mult, which allows the division

As a basic type safety check it makes sure the sizes of source and

COPY_ARRAY is safe to use with NULL as source pointer iff 0 elements are

Although we now run highlight on files which do not end up highlighted,
performance is virtually unaffected because when we call highlight, it
is used for escaping HTML. In the case that highlight is used, gitweb
calls sanitize() instead of esc_html(), and the latter is significantly
slower (it does more, being roughly a superset of sanitize()). Simple
benchmark comparing performance of 'blob' view of files without syntax
highlighting in gitweb before and after this change indicates ±1%
difference in request time for all file types. Benchmark was performed

create_default_files() is supposed to be fed the path to ".git" that
looks as if it is at the top of the working tree, and decide if that
location matches the actual worktree being used. This comparison allows
"git init" to decide if core.worktree needs to be recorded in the
working tree.
In the current code, however, we feed the return value from
get_git_dir(), which can be totally different from what the function

the ".git" at the top of the working tree, we end up feeding the actual
path that the file points at.

Make init_db() save it and have it passed to create_default_files() as a

needs_work_tree_config() to fix this.

init: correct re-initialization from a linked worktree
When 'git init' is called from a linked worktree, we treat '.git'
dir (which is $GIT_COMMON_DIR/worktrees/something) as the main
'.git' (i.e. $GIT_COMMON_DIR) and populate the whole repository skeleton
in there. It does not harm anything (*) but it is still wrong.
Since 'git init' calls set_git_dir() at preparation time, which
indirectly calls get_common_dir() and correctly detects multiple
worktree setup, all git_path_buf() calls in create_default_files() will
return correct paths in both single and multiple worktree setups. The
only thing left is copy_templates(), which targets $GIT_DIR, not
$GIT_COMMON_DIR.
Fix that with get_git_common_dir(). This function will return $GIT_DIR
in single-worktree setup, so we don't have to make a special case for
multiple-worktree here.

fetch-pack: do not reset in_vain on non-novel acks
The MAX_IN_VAIN mechanism was introduced in commit f061e5f ("fetch-pack:
give up after getting too many "ack continue"", 2006-05-24) to stop ref
negotiation if a number of consecutive "have"s have been sent with no
corresponding new acks. This is to stop the client from digging too deep
in an irrelevant side branch in vain without ever finding a common
ancestor. A use case (as described in that commit) is the scenario in
which the local repository has more roots than the remote repository.
However, during a negotiation in which stateless RPCs are used,
MAX_IN_VAIN will (almost) never trigger (in the more-roots scenario
above and others) because in each new request, the client has to inform
the server of objects it already has and knows the server has (to remind
the server of the state), which the server then acks.
Make fetch-pack only consider, as new acks for the purpose of
MAX_IN_VAIN, acks for objects for which the client has never received an
ack before in this session.

ident: handle NULL ai_canonname
We call getaddrinfo() to try to convert a short hostname
into a fully-qualified one (to use it as an email domain).
If there isn't a canonical name, getaddrinfo() will
generally return either a NULL addrinfo list, or one in
which ai->ai_canonname is a copy of the original name.
However, if the result of gethostname() looks like an IP
address, then getaddrinfo() behaves differently on some
systems. On OS X, it will return a "struct addrinfo" with a
NULL ai_canonname, and we segfault feeding it to strchr().
This is hard to test reliably because it involves not only a
system where we we have to fallback to gethostname() to come
up with an ident, but also where the hostname is a number
with no dots. But I was able to replicate the bug by faking
a hostname, like:
and running "git var GIT_AUTHOR_IDENT" on an OS X system.
Before this patch it segfaults, and after we correctly
complain of the bogus "user@1.(none)" address (though this
bogus address would be suitable for non-object uses like
writing reflogs).

and since the child clones inherit the parent stderr, then
both processes would come to the same decision by default.
If the parent clone was asked for "--quiet", we passed down
"--quiet" to the child. However, if stderr was not a tty and
the user specified "--progress", we did not propagate this
to the child.
That's a minor bug, but things got much worse when we
switched recently to submodule--helper's update_clone
command. With that change, the stderr of the child clones
are always connected to a pipe, and we never output
progress at all.
This patch teaches git-submodule and git-submodule--helper
how to pass down an explicit "--progress" flag when cloning.
The clone command then decides to propagate that flag based
on the cloning decision made earlier (which takes into
account isatty(2) of the parent process, existing --progress
or --quiet flags, etc). Since the child processes always run
without a tty on stderr, we don't have to worry about
passing an explicit "--no-progress"; it's the default for
them.
This fixes the recent loss of progress during recursive
clones. And as a bonus, it makes:
git clone --recursive --progress ... 2>&1 | cat
work by triggering progress explicitly in the children.

verify_packfile: check pack validity before accessing data
The verify_packfile() does not explicitly open the packfile;
instead, it starts with a sha1 checksum over the whole pack,
and relies on use_pack() to open the packfile as a side
effect.
If the pack cannot be opened for whatever reason (either
because its header information is corrupted, or perhaps
because a simultaneous repack deleted it), then use_pack()
will die(), as it has no way to return an error. This is not
ideal, as verify_packfile() otherwise tries to gently return
an error (this lets programs like git-fsck go on to check
other packs).
Instead, let's check is_pack_valid() up front, and return an
error if it fails. This will open the pack as a side effect,
and then use_pack() will later rely on our cached
descriptor, and avoid calling die().

A recently introduced test checks the result of 'git status' after
setting the executable bit on a file. This check does not yield the
expected result when the filesystem does not support the executable
bit.
What we care about is that a file added with "--chmod=+x" has
executable bit in the index and that "--chmod=+x" (or any other
options for that matter) does not muck with working tree files.
The former is tested by other existing tests, so let's check the
latter more explicitly and only under POSIXPERM prerequisite.

We need to use this function whenever the buffer we want to pass to
regexec(3) may have been mmap(2)ed (and is hence not NUL-terminated).
Note: the original motivation for this patch was to fix a bug where
`git diff -G <regex>` would crash. This patch converts more callers,
though, some of which allocated to construct NUL-terminated strings,
or worse, modified buffers to temporarily insert NULs while calling
regexec(3). By converting them to use regexec_buf(), the code has
become much cleaner.

regex: add regexec_buf() that can work on a non NUL-terminated string
We just introduced a test that demonstrates that our sloppy use of
regexec() on a mmap()ed area can result in incorrect results or even
hard crashes.
So what we need to fix this is a function that calls regexec() on a
length-delimited, rather than a NUL-terminated, string.
Happily, there is an extension to regexec() introduced by the NetBSD
project and present in all major regex implementation including
Linux', MacOSX' and the one Git includes in compat/regex/: by using
the (non-POSIX) REG_STARTEND flag, it is possible to tell the
regexec() function that it should only look at the offsets between
pmatch[0].rm_so and pmatch[0].rm_eo.
That is exactly what we need.
Since support for REG_STARTEND is so widespread by now, let's just
introduce a helper function that always uses it, and tell people
on a platform whose regex library does not support it to use the
one from our compat/regex/ directory.

regex: -G<pattern> feeds a non NUL-terminated string to regexec() and fails
When our pickaxe code feeds file contents to regexec(), it implicitly
assumes that the file contents are read into implicitly NUL-terminated
buffers (i.e. that we overallocate by 1, appending a single '\0').
This is not so.
In particular when the file contents are simply mmap()ed, we can be
virtually certain that the buffer is preceding uninitialized bytes, or
invalid pages.
Note that the test we add here is known to be flakey: we simply cannot
know whether the byte following the mmap()ed ones is a NUL or not.
Typically, on Linux the test passes. On Windows, it fails virtually
every time due to an access violation (that's a segmentation fault for
you Unix-y people out there). And Windows would be correct: the
regexec() call wants to operate on a regular, NUL-terminated string,
there is no NUL in the mmap()ed memory range, and it is undefined
whether the next byte is even legal to access.
When run with --valgrind it demonstrates quite clearly the breakage, of
course.
Being marked with `test_expect_failure`, this test will sometimes be
declare "TODO fixed", even if it only passes by mistake.
This test case represents a Minimal, Complete and Verifiable Example of
a breakage reported by Chris Sidi.
