Similar to the "grep -F -i" case, we can't use kws on icase search
outside ascii range, so we quote the string and pass it to regcomp as
a basic regexp and let regex engine deal with case sensitivity.
The new test is put in t7812 instead of t4209-log-pickaxe because
lib-gettext.sh might cause problems elsewhere, probably.

In the previous change in this function, we add locale support for
single-byte encodings only. It looks like pcre only supports utf-* as
multibyte encodings, the others are left in the cold (which is
fine).
We need to enable PCRE_UTF8 so pcre can find character boundary
correctly. It's needed for case folding (when --ignore-case is used)
or '*', '+' or similar syntax is used.
The "has_non_ascii()" check is to be on the conservative side. If
there's non-ascii in the pattern, the searched content could still be
in utf-8, but we can treat it just like a byte stream and everything
should work. If we force utf-8 based on locale only and pcre validates
utf-8 and the file content is in non-utf8 encoding, things break.

Similar to the previous commit, we can't use kws on icase search
outside ascii range. But we can't simply pass the pattern to
regcomp/pcre like the previous commit because it may contain regex
special characters, so we need to quote the regex first.
To avoid misquote traps that could lead to undefined behavior, we
always stick to basic regex engine in this case. We don't need fancy
features for grepping a literal string anyway.
basic_regex_quote_buf() assumes that if the pattern is in a multibyte
encoding, ascii chars must be unambiguously encoded as single
bytes. This is true at least for UTF-8. For others, let's wait until
people yell up. Chances are nobody uses multibyte, non utf-8 charsets
anymore.

The ustar format represents timestamps as seconds since the
epoch, but only has room to store 11 octal digits. To
express anything larger, we need to use an extended header.
This is exactly the same case we fixed for the size field in
the previous commit, and the solution here follows the same
pattern.
This is even mentioned as an issue in f2f0267 (archive-tar:
use xsnprintf for trivial formatting, 2015-09-24), but since
it only affected things far in the future, it wasn't deemed
worth dealing with. But note that my calculations claiming
thousands of years were off there; because our xsnprintf
produces a NUL byte, we only have until the year 2242 to fix
this.
Given that this is just around the corner (geologically
speaking, anyway), and because it's easy to fix, let's just
make it work. Unlike the previous fix for "size", where we
had to write an individual extended header for each file, we
can write one global header (since we have only one mtime
for the whole archive).
There's a slight bit of trickiness there. We may already be
writing a global header with a "comment" field for the
commit sha1. So we need to write our new field into the same
header. To do this, we push the decision of whether to write
such a header down into write_global_extended_header(),
which will now assemble the header as it sees fit, and will
return early if we have nothing to write (in practice, we'll
only have a large mtime if it comes from a commit, but this
makes it also work if you set your system clock ahead such
that time() returns a huge value).
Note that we don't (and never did) handle negative
timestamps (i.e., before 1970). This would probably not be
too hard to support in the same way, but since git does not
support negative timestamps at all, I didn't bother here.
After writing the extended header, we munge the timestamp in
the ustar headers to the maximum-allowable size. This is
wrong, but it's the least-wrong thing we can provide to a
tar implementation that doesn't understand pax headers (it's
also what GNU tar does).

The ustar format has a fixed-length field for the size of
each file entry which is supposed to contain up to 11 bytes
of octal-formatted data plus a NUL or space terminator.
These means that the largest size we can represent is
077777777777, or 1 byte short of 8GB. The correct solution
for a larger file, according to POSIX.1-2001, is to add an
extended pax header, similar to how we handle long
filenames. This patch does that, and writes zero for the
size field in the ustar header (the last bit is not
mentioned by POSIX, but it matches how GNU tar behaves with
--format=pax).
This should be a strict improvement over the current
behavior, which is to die in xsnprintf with a "BUG".
However, there's some interesting history here.
Prior to f2f0267 (archive-tar: use xsnprintf for trivial
formatting, 2015-09-24), we silently overflowed the "size"
field. The extra bytes ended up in the "mtime" field of the
header, which was then immediately written itself,
overwriting our extra bytes. What that means depends on how
many bytes we wrote.
If the size was 64GB or greater, then we actually overflowed
digits into the mtime field, meaning our value was
effectively right-shifted by those lost octal digits. And
this patch is again a strict improvement over that.
But if the size was between 8GB and 64GB, then our 12-byte
field held all of the actual digits, and only our NUL
terminator overflowed. According to POSIX, there should be a
NUL or space at the end of the field. However, GNU tar seems
to be lenient here, and will correctly parse a size up 64GB
(minus one) from the field. So sizes in this range might
have just worked, depending on the implementation reading
the tarfile.
This patch is mostly still an improvement there, as the 8GB
limit is specifically mentioned in POSIX as the correct
limit. But it's possible that it could be a regression
(versus the pre-f2f0267 state) if all of the following are
true:
1. You have a file between 8GB and 64GB.
2. Your tar implementation _doesn't_ know about pax
extended headers.
3. Your tar implementation _does_ parse 12-byte sizes from
the ustar header without a delimiter.
It's probably not worth worrying about such an obscure set
of conditions, but I'm documenting it here just in case.

The ustar format only has room for 11 (or 12, depending on
some implementations) octal digits for the size and mtime of
each file. For values larger than this, we have to add pax
extended headers to specify the real data, and git does not
yet know how to do so.
Before fixing that, let's start off with some test
infrastructure, as designing portable and efficient tests
for this is non-trivial.
We want to use the system tar to check our output (because
what we really care about is interoperability), but we can't
rely on it:
1. being able to read pax headers
2. being able to handle huge sizes or mtimes
3. supporting a "t" format we can parse
So as a prerequisite, we can feed the system tar a reference
tarball to make sure it can handle these features. The
reference tar here was created with:
dd if=/dev/zero seek=64G bs=1 count=1 of=huge
touch -d @68719476737 huge
tar cf - --format=pax |
head -c 2048
using GNU tar. Note that this is not a complete tarfile, but
it's enough to contain the headers we want to examine.
Likewise, we need to convince git that it has a 64GB blob to
output. Running "git add" on that 64GB file takes many
minutes of CPU, and even compressed, the result is 64MB. So
again, I pre-generated that loose object, and then took only
the first 2k of it. That should be enough to generate 2MB of
data before hitting an inflate error, which is plenty for us
to generate the tar header (and then die of SIGPIPE while
streaming the rest out).
The tests are split so that we test as much as we can even
with an uncooperative system tar. This actually catches the
current breakage (which is that we die("BUG") trying to
write the ustar header) on every system, and then on systems
where we can, we go farther and actually verify the result.

It is sometimes useful to be able to read exactly N bytes from a
pipe. Doing this portably turns out to be surprisingly difficult
in shell scripts.
We want a solution that:
- is portable
- never reads more than N bytes due to buffering (which
would mean those bytes are not available to the next
program to read from the same pipe)
- handles partial reads by looping until N bytes are read
(or we see EOF)
- is resilient to stray signals giving us EINTR while
trying to read (even though we don't send them, things
like SIGWINCH could cause apparently-random failures)
Some possible solutions are:
- "head -c" is not portable, and implementations may
buffer (though GNU head does not)
- "read -N" is a bash-ism, and thus not portable
- "dd bs=$n count=1" does not handle partial reads. GNU dd
has iflags=fullblock, but that is not portable
- "dd bs=1 count=$n" fixes the partial read problem (all
reads are 1-byte, so there can be no partial response).
It does make a lot of write() calls, but for our tests
that's unlikely to matter. It's fairly portable. We
already use it in our tests, and it's unlikely that
implementations would screw up any of our criteria. The
most unknown one would be signal handling.
- perl can do a sysread() loop pretty easily. On my Linux
system, at least, it seems to restart the read() call
automatically. If that turns out not to be portable,
though, it would be easy for us to handle it.
That makes the perl solution the least bad (because we
conveniently omitted "length of code" as a criterion).
It's also what t9300 is currently using, so we can just pull
the implementation from there.

The "git" command prepends the exec-path to the PATH environment
variable for processes it spawns. That is how ". git-sh-setup" in
our scripted Porcelains can find the dot-sourced file in the
exec-path location that is not usually on user's PATH.
When t2300 runs, because it is not spawned by the "git" command, the
scriptlet being tested did not run with a realistic setting of PATH
environment. It lacked the exec-path on the PATH, and failed to
find the dot-sourced file. A recent update to t2300 attempted to
fix this, with "PATH=$(git --exec-path):$PATH", which has been the
recommended way around v1.6.0 days (a script whose original was
written before that release that survives to this day is likely to
have such a line).
However, the "git --exec-path" command outputs C:\path\to\exec\dir
(not /c/path/to/exec/dir) on Windows; the recent update failed to
consider the problem that comes from it.
Even though Git itself, when doing the equivalent internally, does
so in a platform native way (i.e. on Windows, C:\path\to\exec\dir is
prepended to the existing value of %PATH% using ';' as a component
separator), the result is further massaged by bash and gets turned
into $PATH that uses /c/path/to/exec/dir with ':' separating the
components, which is the form understood by bash, so scripted
Porcelains find commands from PATH correctly.
An end user script written in shell, however, cannot prepend
"C:\path\to\exec\dir:" to the existing value of $PATH and expect
bash to magically turn it into the form it understands. In other
words, "PATH=$(git --exec-path):$PATH" does not work as an emulation
of what "Git" internally does to the PATH on Windows.
To correctly emulate how exec-path is prepended to the PATH
environment internally on Windows, we'd need to convert
C:\git-sdk-64\usr\src\git to at least /c\git-sdk-64\usr\src\git
ourselves before prepending it to PATH.

Commit 7501b59 (perf: make the tests work in worktrees,
2016-05-13) introduced the use of "git rev-parse --git-path"
in the perf-lib setup code. Because the to-be-tested version
of git is at the front of the $PATH when this code runs,
this means we cannot use modern versions of t/perf to test
versions of git older than v2.5.0 (when that option was
introduced).
This is a symptom of a more general problem. The t/perf
suite is essentially independent of git versions, and
ideally we would be able to run the most modern and complete
set of tests across many historical versions (to see how
they compare). But any setup code they run is therefore
required to use the lowest common denominator we expect to
test.
So let's introduce a new variable, $MODERN_GIT, that we can
use both in perf-lib and in the test setup to get a reliable
set of git features (we might change git and break some
tests, of course, but $MODERN_GIT is tied to the same
version of git as the t/perf scripts, so they can be fixed
or adjusted together).
This commit fixes the "--git-path" case, but does not
mass-convert existing setup code to use $MODERN_GIT. Most
setup code is fairly vanilla and will work with effectively
all versions. But now the tool is there to fix any other
issues we find going forward.

When we want to know the local timezone offset at a given

However, there's some juggling between time_t and "struct

tm_to_time_t().
If that function returns an error (e.g., because it only

we treat as a time_t, and is clearly bogus, leading to
bizarre timestamps (that seem to always adjust the time back

It's not a good idea for local_tzoffset() to simply die

If you use "repack -adk" currently, we will pack all objects
that are already packed into the new pack, and then drop the
old packs. However, loose unreachable objects will be left
as-is. In theory these are meant to expire eventually with
"git prune". But if you are using "repack -k", you probably
want to keep things forever and therefore do not run "git
prune" at all. Meaning those loose objects may build up over
time and end up fooling any object-count heuristics (such as
the one done by "gc --auto", though since git-gc does not
support "repack -k", this really applies to whatever custom
scripts people might have driving "repack -k").
With this patch, we instead stuff any loose unreachable
objects into the pack along with the already-packed
unreachable objects. This may seem wasteful, but it is
really no more so than using "repack -k" in the first place.
We are at a slight disadvantage, in that we have no useful
ordering for the result, or names to hand to the delta code.
However, this is again no worse than what "repack -k" is
already doing for the packed objects. The packing of these
objects doesn't matter much because they should not be
accessed frequently (unless they actually _do_ become
referenced, but then they would get moved to a different
part of the packfile during the next repack).

The usual way to do a full repack (and what is done by
git-gc) is to run "repack -Ad --unpack-unreachable=<when>",
which will loosen any unreachable objects newer than
"<when>", and drop any older ones.
This is a safer alternative to "repack -ad", because
"<when>" becomes a grace period during which we will not
drop any new objects that are about to be referenced.
However, it isn't perfectly safe. It's always possible that
a process is about to reference an old object. Even if that
process were to take care to update the timestamp on the
object, there is no atomicity with a simultaneously running
"repack" process.
So while unlikely, there is a small race wherein we may drop
an object that is in the process of being referenced. If you
do automated repacking on a large number of active
repositories, you may hit it eventually, and the result is a
corrupted repository.
It would be nice to fix that race in the long run, but it's
complicated. In the meantime, there is a much simpler
strategy for automated repository maintenance: do not drop
objects at all. We already have a "--keep-unreachable"
option in pack-objects; we just need to plumb it through
from git-repack.
Note that this _isn't_ plumbed through from git-gc, so at
this point it's strictly a tool for people doing their own
advanced repository maintenance strategy.

There are two types of string_lists: those that own the
string memory, and those that don't. You can tell the
difference by the strdup_strings flag, and one should use
either STRING_LIST_INIT_DUP, or STRING_LIST_INIT_NODUP as an
initializer.
Historically, the normal all-zeros initialization has
corresponded to the NODUP case. Many sites use no
initializer at all, and that works as a shorthand for that
case. But for a reader of the code, it can be hard to
remember which is which. Let's be more explicit and actually
have each site declare which type it means to use.
This is a fairly mechanical conversion; I assumed each site

If a repository contains more than one root commit, then its HEAD
reflog may contain multiple "creation events", i.e. entries whose
"from" value is the null sha1. Listing such a reflog currently stops
prematurely at the first such entry, even when the reflog still
contains older entries. This can scare users into thinking that their
reflog got truncated after 'git checkout --orphan'.
Continue walking the reflog past such creation events based on the
preceeding reflog entry's "new" value.
The test 'symbolic-ref writes reflog entry' in t1401-symbolic-ref
implicitly relies on the current behavior of the reflog walker to stop
at a root commit and thus to list only the reflog entries that are
relevant for that test. Adjust the test to explicitly specify the
number of relevant reflog entries to be listed.

This output format prevents format-patch output from breaking
readers if somebody copy+pasted an mbox into a commit message.
Unlike the traditional "mboxo" format, "mboxrd" is designed to
be fully-reversible. "mboxrd" also gracefully degrades to
showing extra ">" in existing "mboxo" readers.
This degradation is preferable to breaking message splitting
completely, a problem I've seen in "mboxcl" due to having
multiple, non-existent, or inaccurate Content-Length headers.
"mboxcl2" is a non-starter since it's inherits the problems
of "mboxcl" while being completely incompatible with existing

CSS is widely used, motivating it being included as a built-in pattern.
It must be noted that the word_regex for CSS (i.e. the regex defining
what is a word in the language) does not consider '.' and '#' characters
(in CSS selectors) to be part of the word. This behavior is documented
by the test t/t4018/css-rule.
The logic behind this behavior is the following: identifiers in CSS
selectors are identifiers in a HTML/XML document. Therefore, the '.'/'#'
character are not part of the identifier, but an indicator of the nature
of the identifier in HTML/XML (class or id). Diffing ".class1" and
".class2" must show that the class name is changed, but we still are
selecting a class.
Logic behind the "pattern" regex is:
1. reject lines ending with a colon/semicolon (properties)
2. if a line begins with a name in column 1, pick the whole line

perf: make the tests work without a worktree
If you ask rev-list for:
git rev-list --count --use-bitmap-index HEAD
we optimize out the actual traversal and just give you the
number of bits set in the commit bitmap. This is faster,
which is good.
But if you ask to limit the size of the traversal, like:
git rev-list --count --use-bitmap-index -n 100 HEAD
we'll still output the full bitmapped number we found. On
the surface, that might even seem OK. You explicitly asked
to use the bitmap index, and it was cheap to compute the
real answer, so we gave it to you.
But there's something much more complicated going on under
the hood. If we don't have a bitmap directly for HEAD, then
we have to actually traverse backwards, looking for a
bitmapped commit. And _that_ traversal is bounded by our
`-n` count.
This is a good thing, because it bounds the work we have to
do, which is probably what the user wanted by asking for
`-n`. But now it makes the output quite confusing. You might
get many values:
- your `-n` value, if we walked back and never found a
bitmap (or fewer if there weren't that many commits)
- the actual full count, if we found a bitmap root for
every path of our traversal with in the `-n` limit
- any number in between! We might have walked back and
found _some_ bitmaps, but then cut off the traversal
early with some commits not accounted for in the result.
So you cannot even see a value higher than your `-n` and say
"OK, bitmaps kicked in, this must be the real full count".
The only sane thing is for git to just clamp the value to a
maximum of the `-n` value, which means we should output the
exact same results whether bitmaps are in use or not.
The test in t5310 demonstrates this by using `-n 1`.
Without this patch we fail in the full-bitmap case (where we
do not have to traverse at all) but _not_ in the
partial-bitmap case (where we have to walk down to find an
actual bitmap). With this patch, both cases just work.
I didn't implement the crazy in-between case, just because
it's complicated to set up, and is really a subset of the
full-count case, which we do cover.

When upload-pack serves a client request, it turns to
pack-objects to do the heavy lifting of creating a
packfile. There's no easy way to intercept the call to
pack-objects, but there are a few good reasons to want to do
so:
1. If you're debugging a client or server issue with
fetching, you may want to store a copy of the generated
packfile.
2. If you're gathering data from real-world fetches for
performance analysis or debugging, storing a copy of
the arguments and stdin lets you replay the pack
generation at your leisure.
3. You may want to insert a caching layer around
pack-objects; it is the most CPU- and memory-intensive
part of serving a fetch, and its output is a pure
function[1] of its input, making it an ideal place to
consolidate identical requests.
This patch adds a simple "hook" interface to intercept calls
to pack-objects. The new test demonstrates how it can be
used for debugging (using it for caching is a
straightforward extension; the tricky part is writing the
actual caching layer).
This hook is unlike the normal hook scripts found in the
"hooks/" directory of a repository. Because we promise that
upload-pack is safe to run in an untrusted repository, we
cannot execute arbitrary code or commands found in the
repository (neither in hooks/, nor in the config). So
instead, this hook is triggered from a config variable that
is explicitly ignored in the per-repo config.
The config variable holds the actual shell command to run as
the hook. Another approach would be to simply treat it as a
boolean: "should I respect the upload-pack hooks in this
repo?", and then run the script from "hooks/" as we usually
do. However, that isn't as flexible; there's no way to run a
hook approved by the site administrator (e.g., in
"/etc/gitconfig") on a repository whose contents are not
trusted. The approach taken by this patch is more
fine-grained, if a little less conventional for git hooks
(it does behave similar to other configured commands like
diff.external, etc).
[1] Pack-objects isn't _actually_ a pure function. Its
output depends on the exact packing of the object
database, and if multi-threading is used for delta
compression, can even differ racily. But for the
purposes of caching, that's OK; of the many possible
outputs for a given input, it is sufficient only that we
output one of them.

In t5500::check_prot_host_port_path(), diagport is not a variable
used elsewhere and the function is not recursively called so this

(besides, the function liberally clobbers other variables without
making them "local").
t7403::reset_submodule_urls() overrides the "root" variable used
in the test framework for no good reason; its use is not about
temporarily relocating where the test repositories are created.
This assignment can be made not to clobber the variable by moving
them into the subshells it already uses. Its value is always
$TRASH_DIRECTORY, so we could use it instead there, and this
function that is called only once and its two subshells may not be
necessary (instead, the caller can use "git -C $there config" and
set a value that is derived from $TRASH_DIRECTORY), but this is a

The one-shot environment variable syntax:
FOO=BAR some-program
is unportable when some-program is actually a shell
function, like test_must_fail (on some shells FOO remains
set after the function returns, and on others it does not).
We sometimes get around this by using env, like:
test_must_fail env FOO=BAR some-program
But that only works because test_must_fail's arguments are
themselves a command which can be run. You can't run:
env FOO=BAR test_must_fail some-program
because env does not know about our shell functions. So
there is no equivalent for test_commit, for example, and one
must resort to:
(
FOO=BAR
export FOO
test_commit
)
which is a bit verbose. Let's add a version of "env" that
works _inside_ the shell, by creating a subshell, exporting
variables from its argument list, and running the command.

penalize being on a side branch of a merge. The logic has been
updated to favor using the tag with the oldest tagger date, which
is a lot easier to explain to the end users: "We describe a commit
in terms of the (chronologically) oldest tag that contains the
commit."

In regular repositories $source_git and $objects_dir contain relative

Empty lines between functions are shown by grep -W, as it considers them
to be part of the function preceding them. They are not interesting in
most languages. The previous patches stopped showing them for diff -W.
Stop showing empty lines trailing a function with grep -W. Grep scans
the lines of a buffer from top to bottom and prints matching lines
immediately. Thus we need to peek ahead in order to determine if an
empty line is part of a function body and worth showing or not.
Remember how far ahead we peeked in order to avoid having to do so
repeatedly when handling multiple consecutive empty lines.

Add a test demonstrating that git grep -W prints empty lines following
the function context we're actually interested in. The modified test
file makes it necessary to adjust three unrelated test cases.

The function trim_common_tail() exits early if context lines are
requested. If -U0 and -W are specified together then it can still trim
context lines that might belong to a changed function. As a result
that function is shown incompletely.
Fix that by calling trim_common_tail() only if no function context or
fixed context is requested. The parameter ctx is no longer needed now;
remove it.
While at it fix an outdated comment as well.

Empty lines between functions are shown by diff -W, as it considers them
to be part of the function preceding them. They are not interesting in
most languages. The previous patch stopped showing them in the special
case of a function added at the end of a file.
Stop extending context to those empty lines by skipping back over them
from the start of the next function.

If a new function and a preceding empty line is appended, diff -W shows
the previous function in full in order to provide context for that empty
line. In most languages empty lines between sections are not
interesting in and off themselves and showing a whole extra function for
them is not what we want.
Skip empty lines when checking of the appended chunk starts with a
function line, thereby avoiding to extend the context just for them.

If lines are added at the end of a file, diff -W shows the whole file.
That's because get_func_line() only considers the pre-image and gives up
if it sees a record index beyond its end.
Consider the post-image as well to see if the added lines already make
up a full function. If it doesn't then search for the previous function
line by starting from the bottom of the pre-image, thereby avoiding to
confuse get_func_line().
Reuse the existing label called "again", as it's exactly where we need
to jump to when we're done handling the pre-context, but rename it to
"post_context_calculation" in order to document its new purpose better.

Remove the tests that checked against a fixed result and replace them
with more focused checks of desired properties of the created diffs.
That way we get more detailed and meaningful diagnostics.
Store test file contents in files in a subdirectory in order to avoid
cluttering the test script with them.
Use tagged commits to store the changes to test diff -W against instead
of using changes to the worktree. Use the worktree instead to try and
apply the generated patch in order to validate it.
Document unwanted features: trailing empty lines, too much context for
appended functions, insufficient context at the end with -U0.

Since `git worktree add` uses `git checkout` when `[<branch>]` is used,
and `git checkout -` is already supported, it makes sense to allow the
same shortcut in `git worktree add`.
