When c5c31d33 (grep: move pattern-type bits support to top-level
grep.[ch], 2012-10-03) introduced grep_commit_pattern_type() helper
function, the intention was to allow the users of grep API to having
to fiddle only with .pattern_type_option (which can be set to "fixed",
"basic", "extended", and "pcre"), and then immediately before compiling
the pattern strings for use, call grep_commit_pattern_type() to have
it prepare various bits in the grep_opt structure (like .fixed,
.regflags, etc.).
However, grep_set_pattern_type_option() helper function the grep API
internally uses were left as an external function by mistake. This
function shouldn't have been made callable by the users of the API.
Later when the grep API was used in revision traversal machinery,
the caller then mistakenly started calling the function around
34a4ae55 (log --grep: use the same helper to set -E/-F options as
"git grep", 2012-10-03), instead of setting the .pattern_type_option
field and letting the grep_commit_pattern_type() to take care of the
details.
This caused an unnecessary bug that made a configured
grep.patternType take precedence over the command line options
(e.g. --basic-regexp, --fixed-strings) in "git log" family of
commands.

When accessing a blob for a diff, we may try to reuse file
contents in the working tree, under the theory that it is
faster to mmap those file contents than it would be to
extract the content from the object database.
When we have to filter those contents, though, that
assumption does not hold. Even for our internal conversions
like CRLF, we have to allocate and fill a new buffer anyway.
But much worse, for external clean filters we have to exec
an arbitrary script, and we have no idea how expensive it
may be to run.
So let's skip this optimization when conversion into git's
"clean" form is required. This applies whenever the
"want_file" flag is false. When it's true, the caller
actually wants the smudged worktree contents, which the
reused file by definition already has (in fact, this is a
key optimization going the other direction, since reusing
the worktree file there lets us skip smudge filters).

When the GPG prereq is not set, we do not run test 34. That
test changes the directory of the test script as a side
effect (something we usually frown on, but which matches the
style of the rest of this script). When test 35 (the
url-scrubbing test) runs, it expects to be in the directory
from test 34. If it's not, the test fails; we are in a
different sub-repo, our test-commit is built on a different
history, and the push becomes a non-fast-forward.
We can fix this by unconditionally moving to the directory
we expect (again, against our usual style but matching how
the rest of the script operates).
As an additional protection, let's also switch from "make a
new commit and push to master" to just "push to a new
branch". We don't care about the branch name; we just want
_some_ ref update to trigger the status output. Pushing to a
new branch is less likely to run into problems with
force-updates, changing the checked-out branch, etc.

When reporting broken links between commits/trees/blobs, it would be
quite helpful at times if the user would be told how the object is
supposed to be reachable.
With the new --name-objects option, git-fsck will try to do exactly
that: name the objects in a way that shows how they are reachable.
For example, when some reflog got corrupted and a blob is missing that
should not be, the user might want to remove the corresponding reflog
entry. This option helps them find that entry: `git fsck` will now
report something like this:

and displayed as being "Not Committed Yet".
However, when blaming a file that is not known to the current HEAD,

Allowing such a blame is useful when the new file added to the index

Commit 3cf773e (cache-tree: fix writing cache-tree when CE_REMOVE is
present - 2012-12-16) skips i-t-a entries when building trees objects
from the index. Unfortunately it may skip too much.
The code in question checks if an entry is an i-t-a one, then no tree
entry will be written. But it does not take into account that
directories can also be written with the same code. Suppose we have
this in the index.
a-file
subdir/file1
subdir/file2
subdir/file3
the-last-file
We write an entry for a-file as normal and move on to subdir/file1,
where we realize the entry name for this level is simply just
"subdir", write down an entry for "subdir" then jump three items ahead
to the-last-file.
That is what happens normally when the first file in subdir is not an
i-t-a entry. If subdir/file1 is an i-t-a, because of the broken
condition in this code, we still think "subdir" is an i-t-a file and
not writing "subdir" down and jump to the-last-file. The result tree
now only has two items: a-file and the-last-file. subdir should be
there too (even though it only records two sub-entries, file2 and
file3).
If the i-t-a entry is subdir/file2 or subdir/file3, this is not a
problem because we jump over them anyway. Which may explain why the
bug is hidden for nearly four years.
Fix it by making sure we only skip i-t-a entries when the entry in
question is actual an index entry, not a directory.

When we tried to fix in 58461bd (t1308: do not get fooled by symbolic
links to the source tree, 2016-06-02) an obscure case where the user
cd's into Git's source code via a symbolic link, a regression was
introduced that affects all test runs on Windows.
The original patch introducing the test case in question was careful to
use `$(pwd)` instead of `$PWD`.
This was done to account for the fact that Git's test suite uses shell
scripting even on Windows, where the shell's Unix-y paths are
incompatible with the main Git executable's idea of paths: it only
accepts Windows paths.
It is an awkward but necessary thing, then, to use `$(pwd)` (which gives
us a Windows path) when interacting with the Git executable and `$PWD`
(which gives the shell's idea of the current working directory in Unix-y
form) for shell scripts, including the test suite itself.
Obviously this broke the use case of the Git maintainer when changing
the working directory into Git's source code directory via a symlink,
i.e. when `$(pwd)` does not agree with `$PWD`.
However, we must not fix that use case at the expense of regressing
another use case.
Let's special-case Windows here, even if it is ugly, for lack of a more
elegant solution.

Commit 47abd85 (fetch: Strip usernames from url's before

The primary purpose there was to avoid sticking passwords in

The push side does not have the merge-commit problem, but it
probably should avoid printing them to stderr. We can reuse

Note that for this to come up, the credentials would have to
appear either on the command line or in a git config file,
neither of which is particularly secure. So people _should_
be switching to using credential helpers instead, which
makes this problem go away. But that's no excuse not to

For blobs, we want to make sure the on-disk data is not corrupted
(i.e. can be inflated and produce the expected SHA-1). Blob content is
opaque, there's nothing else inside to check for.
For really large blobs, we may want to avoid unpacking the entire blob
in memory, just to check whether it produces the same SHA-1. On 32-bit
systems, we may not have enough virtual address space for such memory
allocation. And even on 64-bit where it's not a problem, allocating a
lot more memory could result in kicking other parts of systems to swap
file, generating lots of I/O and slowing everything down.
For this particular operation, not unpacking the blob and letting
check_sha1_signature, which supports streaming interface, do the job
is sufficient. check_sha1_signature() is not shown in the diff,
unfortunately. But if will be called when "data_valid && !data" is
false.
We will call the callback function "fn" with NULL as "data". The only
callback of this function is fsck_obj_buffer(), which does not touch
"data" at all if it's a blob.

When merge_recursive() decides what the correct blob object merge
result for a path should be, it uses update_file_flags() helper
function to write it out to a working tree file and then calls
add_cacheinfo(). The add_cacheinfo() function in turn calls
make_cache_entry() to create a new cache entry to replace the
higher-stage entries for the path that represents the conflict.
The make_cache_entry() function calls refresh_cache_entry() to fill
in the cached stat information. To mark a cache entry as
up-to-date, the data is re-read from the file in the working tree,
and goes through convert_to_git() conversion to be compared with the
blob object name the new cache entry records.
It is important to note that this happens while the higher-stage
entries, which are going to be replaced with the new entry, are
still in the index. Unfortunately, the convert_to_git() conversion
has a misguided "safer crlf" mechanism baked in, and looks at the
existing cache entry for the path to decide how to convert the
contents in the working tree file. If our side (i.e. stage#2)
records a text blob with CRLF in it, even when the system is
configured to record LF in blobs and convert them to CRLF upon
checkout (and back to LF upon checkin), the "safer crlf" mechanism
stops us doing so.
This especially poses a problem during a renormalizing merge, where
the merge result for the path is computed by first "normalizing" the
blobs involved in the merge by using convert_to_working_tree()
followed by convert_to_git() with "safer crlf" disabled. The merge
result that is computed correctly and fed to add_cacheinfo() via
update_file_flags() does _not_ match what refresh_cache_entry() sees
by converting the working tree file via convert_to_git().
We can work this around by not refreshing the new cache entry in
make_cache_entry() called by add_cacheinfo(). After add_cacheinfo()
adds the new entry, we can call refresh_cache_entry() on that,
knowing that addition of this new cache entry would have removed the
stale cache entries that had CRLF in stage #2 that were carried over
before the renormalizing merge started and will not interfere with
the correct recording of the result.

For the record, this output is not perfect. A single giant ref can
push all refs very far to the right and likely be wrapped around. We
may have a few options:
- exclude these long lines smarter
- break the line after "->", exclude it from column width calculation
- implement a new format, { -> origin/}foo, which makes the problem

- reverse all the arrows so we have "* <- looong-ref", again still

In POSIX shells, a program which exits due to a signal
generally has an exit code of 128 plus the signal number.
However, ksh uses 256 plus the signal number. We've
accounted for that in t0005, but not in other tests. Let's
pull out the logic so we can use it elsewhere.
It would be nice for debugging if this additionally printed
errors to stderr, like our other test_* helpers. But we're
going to need to use it in other places besides the innards
of a test_expect block. So let's leave it as generic as
possible.
Note that we also leave the magic "3" for Windows out of the
generic helper. This is an artifact of the way we use
raise() to kill ourselves in test-sigchain.c, and will not
necessarily apply to all programs. So it's better to keep it
out of the helper, to reduce the chance of confusing it with
a real call to exit(3).

This reverts commit 4d5520053 (grep: make it clear i-t-a entries are
ignored, 2015-12-27) and adds an alternative fix to maintain the -L
--cached behavior.
4d5520053 caused 'git grep' to no longer find matches in new files in
the working tree where the corresponding index entry had the "intent to
add" bit set, despite the fact that these files are tracked.
The content in the index of a file for which the "intent to add" bit is
set is considered indeterminate and not empty. For most grep queries we
want these to behave the same, however for -L --cached (files without a
match) we don't want to respond positively for "intent to add" files as
their contents are indeterminate. This is in contrast to files with
empty contents in the index (no lines implies no matches for any grep
query expression) which should be reported in the output of a grep -L
--cached invocation.
Add tests to cover this case and a few related cases which previously
lacked coverage.

In the previous change in this function, we add locale support for

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

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.
