Commit d53c2c6 (mingw: fix t9700's assumption about
directory separators, 2016-01-27) uses perl's "/r" regex
modifier to do a non-destructive replacement on a string,
leaving the original unmodified and returning the result.
This feature was introduced in perl 5.14, but systems with
older perl are still common (e.g., CentOS 6.5 still has perl
5.10). Let's work around it by providing a helper function
that does the same thing using older syntax.
While we're at it, let's switch to using an alternate regex
separator, which is slightly more readable.

When 592ce208 (index-pack: use strip_suffix to avoid magic numbers,
2014-06-30) refactored the code to derive names of .idx and .keep
files from the name of .pack file, a copy-and-paste typo crept in,
mistakingly attempting to create and store the keep message file in
the .idx file we just created, instead of .keep file.
As we create the .keep file with O_CREAT|O_EXCL, and we do so after
we write the .idx file, we luckily do not clobber the .idx file, but
because we deliberately ignored EEXIST when creating .keep file
(which is justifiable because only the existence of .keep file
matters), nobody noticed this mistake so far.

Once upon a time, you could use "--local-env-vars" and
"--resolve-git-dir" outside of any git repository, but they
had to come first on the command line. Commit 68889b4
(rev-parse: remove restrictions on some options, 2013-07-21)
put them into the normal option-parsing loop, fixing the
latter. But it inadvertently broke the former, as we call
setup_git_directory() before starting that loop.
We can note that those options don't care even conditionally
about whether we are in a git repo. So it's fine if we
simply wait to setup the repo until we see an option that
needs it.
However, there is one special exception we should make:
historically, rev-parse will set up the repository and read
config even if there are _no_ options. Some of the
tests in t1300 rely on this to check "git -c $config"
parsing. That's not mirroring real-world use, and we could
tweak the test. But t0002 uses a bare "git rev-parse" to
check "are we in a git repository?". It's plausible that
real-world scripts are relying on this.
So let's cover this case specially, and treat an option-less
"rev-parse" as "see if we're in a repo".

A v2 pack index file can specify an offset within a packfile
of up to 2^64-1 bytes. On a system with a signed 64-bit
off_t, we can represent only up to 2^63-1. This means that a
corrupted .idx file can end up with a negative offset in the
pack code. Our bounds-checking use_pack function looks for
too-large offsets, but not for ones that have wrapped around
to negative. Let's do so, which fixes an out-of-bounds
access demonstrated in t5313.
Signed-off-by: Jeff King <peff@peff.net>
Signed-off-by: Junio C Hamano <gitster@pobox.com>
If a pack .idx file has a corrupted offset for an object, we
may try to access an offset in the .idx or .pack file that
is larger than the file's size. For the .pack case, we have
use_pack() to protect us, which realizes the access is out
of bounds. But if the corrupted value asks us to look in the
.idx file's secondary 64-bit offset table, we blindly add it
to the mmap'd index data and access arbitrary memory.
We can fix this with a simple bounds-check compared to the
size we found when we opened the .idx file.
Note that there's similar code in index-pack that is
triggered only during "index-pack --verify". To support
both, we pull the bounds-check into a separate function,
which dies when it sees a corrupted file.
It would be nice if we could return an error, so that the
pack code could try to find a good copy of the object
elsewhere. Currently nth_packed_object_offset doesn't have
any way to return an error, but it could probably use "0" as
a sentinel value (since no object can start there). This is
the minimal fix, and we can improve the resilience later on
top.

Our on-disk .pack and .idx files may reference other data by
offset. We should make sure that we are not fooled by
corrupt data into accessing memory outside of our mmap'd
boundaries.
This patch adds a series of tests for offsets found in .pack
and .idx files. For the most part we get this right, but
there are two tests of .idx files marked as failures: we do
not bounds-check offsets in the v2 index's extended offset
table, nor do we handle .idx offsets that overflow a signed
off_t.
With these tests, we should have good coverage of all
offsets found in these files. Note that this doesn't cover
.bitmap files, which may have similar bugs.

This is the test missing from fb86e32 (git remote: allow adding

Both remote add and remote rename use a slightly different hand-rolled
check if the remote exits. The hand-rolled check may have some subtle
cases in which it might fail to detect when a remote already exists.
One such case was fixed in fb86e32 ("git remote: allow adding remotes
agreeing with url.<...>.insteadOf"). Another case is when a remote is
configured as follows:
[remote "foo"]
vcs = bar
If we try to run `git remote add foo bar` with the above remote
configuration, git segfaults. This change fixes it.
In addition, git remote rename $existing foo with the configuration for
foo as above silently succeeds, even though foo already exists,
modifying its configuration. With this patch it fails with "remote foo
already exists".

When converting the git remote command to a builtin in 211c89 ("Make
git-remote a builtin"), a few calls to check if a remote exists were
converted from:
if (!exists $remote->{$name}) {
[...]
to:
remote = remote_get(argv[1]);
if (!remote)
[...]
The new check is not quite correct, because remote_get() never returns
NULL if a name is given. This leaves us with the somewhat cryptic error
message "error: Could not remove config section 'remote.test'", if we
are trying to remove a remote that does not exist, or a similar error if
we try to rename a remote.
Use the remote_is_configured() function to check whether the remote
actually exists, and die with a more sensible error message ("No such
remote: $remotename") instead if it doesn't.

If --force is not given but -B is, we should not proceed if the given

but it kicks in too late when "git branch --force" is already
executed. As a result, even though we correctly refuse to create a new

The get_sha1() function generally returns an error code
rather than dying, and we sometimes speculatively call it
with something that may be a revision or a pathspec, in
order to see which one it might be.
If it sees a bogus ":/" search string, though, it complains,
without giving the caller the opportunity to recover. We can
demonstrate this in t6133 by looking for ":/*.t", which
should mean "*.t at the root of the tree", but instead dies
because of the invalid regex (the "*" has nothing to operate
on).
We can fix this by returning an error rather than calling
die(). Unfortunately, the tradeoff is that the error message
is slightly worse in cases where we _do_ know we have a rev.
E.g., running "git log ':/*.t' --" before yielded:
fatal: Invalid search pattern: *.t
and now we get only:
fatal: bad revision ':/*.t'
There's not a simple way to fix this short of passing a
"quiet" flag all the way through the get_sha1() stack.

When specifying both revisions and pathnames, we allow
"<rev> -- <pathspec>" to be spelled without the "--" as long
as it is not ambiguous. The original logic was something
like:
1. Resolve each item with get_sha1(). If successful,
we know it can be a <rev>. Verify that it _isn't_ a
filename, using verify_non_filename(), and complain of
ambiguity otherwise.
2. If get_sha1() didn't succeed, make sure that it _is_
a file, using verify_filename(). If not, complain
that it is neither a <rev> nor a <pathspec>.
Both verify_filename() and verify_non_filename() rely on
check_filename(), which definitely said "yes, this is a
file" or "no, it is not" using lstat().
Commit 28fcc0b (pathspec: avoid the need of "--" when
wildcard is used, 2015-05-02) introduced a convenience
feature: check_filename() will consider anything with
wildcard meta-characters as a possible filename, without
even checking the filesystem.
This works well for case 2. For such a wildcard, we would
previously have died and said "it is neither". Post-28fcc0b,
we assume it's a pathspec and proceed.
But it makes some instances of case 1 worse. We may have an
extended sha1 expression that contains meta-characters
(e.g., "HEAD^{/foo.*bar}"), and we now complain that it's
also a filename, due to the wildcard characters (even though
that wildcard would not match anything in the filesystem).
One solution would be to actually expand the pathname and
see if it matches anything on the filesystem. But that's
potentially expensive, and we do not have to be so rigorous
for this DWIM magic (if you want rigor, use "--").
Instead, we can just use different rules for cases 1 and 2.
When we know something is a rev, we will complain only if it
meets a much higher standard for "this is also a file";
namely that it actually exists in the filesystem. Case 2
remains the same: we use the looser "it could be a filename"
standard introduced by 28fcc0b.
We can accomplish this by pulling the wildcard logic out of
check_filename() and putting it into verify_filename(). Its
partner verify_non_filename() does not need a change, since
check_filename() goes back to implementing the "higher
standard".
Besides these two callers of check_filename(), there is one
other: git-checkout does a similar DWIM itself. It hits this
code path only after get_sha1() has returned failure, making
it case 2, which gets the special wildcard treatment.
Note that we drop the tests in t2019 in favor of a more
complete set in t6133. t2019 was not the right place for
them (it's about refname ambiguity, not dwim parsing
ambiguity), and the second test explicitly checked for the
opposite result of the case we are fixing here (which didn't
really make any sense; as shown by the test_must_fail in the
test, it would only serve to annoy people).

It used to be that:
git config --global user.email "(none)"
was a viable way for people to force themselves to set user.email in
each repository. This was helpful for people with more than one
email address, targeting different email addresses for different
clones, as it barred git from creating a commit unless the user.email
config was set in the per-repo config to the correct email address.
A recent change, 19ce497c (ident: keep a flag for bogus
default_email, 2015-12-10), however, declared that an explicitly
configured user.email is not bogus, no matter what its value is, so
this hack no longer works.
Provide the same functionality by adding a new configuration
variable user.useConfigOnly; when this variable is set, the
user must explicitly set user.email configuration.
