13e0b0d3dc use_pack: handle signed off_t overflow
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.

47fe3f6ef0 nth_packed_object_offset: bounds-check extended offset
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.

a1283866ba t5313: test bounds-checks of corrupted/malicious pack/idx files
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.

27852b2c53 branch: report errors in tracking branch setup
When setting up a new tracking branch fails due to issues with
the configuration file we do not report any errors to the user
and pretend setting the tracking branch succeeded.

Setting up the tracking branch is handled by the
`install_branch_config` function. We do not want to simply die
there as the function is not only invoked when explicitly setting
upstream information with `git branch --set-upstream-to=`, but
also by `git push --set-upstream` and `git clone`. While it is
reasonable to die in the explict first case, we would lose
information in the latter two cases, so we only print the error
message but continue the program as usual.

a31eeae27f remote: use remote_is_configured() for add and rename
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".

cc8e538d45 remote: actually check if remote exits
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.

beb6f24bee worktree add -B: do the checkout test before update branch
If --force is not given but -B is, we should not proceed if the given
branch is already checked out elsewhere. add_worktree() has this test,
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
worktree, we have already updated the branch and mess up the other
checkout.

Repeat the die_if_checked_out() test again for this specific case before
"git branch" runs.

0ebf4a2af3 worktree: fix "add -B"
Current code does not update "symref" when -B is used. This string
contains the new HEAD. Because it's empty "git worktree add -B" fails at
symbolic-ref step.

Because branch creation is already done before calling add_worktree(),
-B is equivalent to -b from add_worktree() point of view. We do not need

aac4fac168 get_sha1: don't die() on bogus search strings
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.

df714f81a7 check_filename: tighten dwim-wildcard ambiguity
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).

4d5c295696 ident: add user.useConfigOnly boolean for when ident shouldn't be guessed
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.

6129c930b2 test-lib: limit the output of the yes utility
On Windows, there is no SIGPIPE. A consequence of this is that the
upstream process of a pipe does not notice the death of the downstream
process until the pipe buffer is full and writing more data returns an
error. This behavior is the reason for an annoying delay during the
execution of t7610-mergetool.sh: There are a number of test cases where
'yes' is invoked upstream. Since the utility is basically an endless
loop it runs, on Windows, until the pipe buffer is full. This does take
a few seconds.

The test suite has its own implementation of 'yes'. Modify it to produce
only a limited amount of output that is sufficient for the test suite.
The amount chosen should be sufficiently high for any test case, assuming
that future test cases will not exaggerate their demands of input from
an upstream 'yes' invocation.

0769854f3d object name: introduce '^{/!-<negative pattern>}' notation
To name a commit, you can now use the :/!-<negative pattern> regex
style, and consequentially, say

    $ git rev-parse HEAD^{/!-foo}

and it will return the hash of the first commit reachable from HEAD,
whose commit message does not contain "foo". This is the opposite of the
existing <rev>^{/<pattern>} syntax.

The specific use-case this is intended for is to perform an operation,
excluding the most-recent commits containing a particular marker. For
example, if you tend to make "work in progress" commits, with messages
beginning with "WIP", you work, then it could be useful to diff against
"the most recent commit which was not a WIP commit". That sort of thing
now possible, via commands such as:

    $ git diff @^{/!-^WIP}

The leader '/!-', rather than simply '/!', to denote a negative match,
is chosen to leave room for additional modifiers in the future.

0d0bac67ce transport: drop support for git-over-rsync
The git-over-rsync protocol is inefficient and broken, and
has been for a long time. It transfers way more objects than
it needs (grabbing all of the remote's "objects/",
regardless of which objects we need). It does its own ad-hoc
parsing of loose and packed refs from the remote, but
doesn't properly override packed refs with loose ones,
leading to garbage results (e.g., expecting the other side
to have an object pointed to by a stale packed-refs entry,
or complaining that the other side has two copies of the
refs[1]).

This latter breakage means that nobody could have
successfully pulled from a moderately active repository
since cd547b4 (fetch/push: readd rsync support, 2007-10-01).

We never made an official deprecation notice in the release
notes for git's rsync protocol, but the tutorial has marked
it as such since 914328a (Update tutorial., 2005-08-30).
And on the mailing list as far back as Oct 2005, we can find
Junio mentioning it as having "been deprecated for quite
some time."[2,3,4]. So it was old news then; cogito had
deprecated the transport in July of 2005[5] (though it did
come back briefly when Linus broke git-http-pull!).

Of course some people professed their love of rsync through

  No. You're using rsync because you're actively doing
  something _wrong_.

The deprecation sentiment was reinforced in 2008, with a
mention that cloning via rsync is broken (with no fix)[7].

Even the commit porting rsync over to C from shell (cd547b4)
lists it as deprecated! So between the 10 years of informal
warnings, and the fact that it has been severely broken
since 2007, it's probably safe to simply remove it without
further deprecation warnings.

1a8630dc3b convert: treat an empty string for clean/smudge filters as "cat"
Once a lower-priority configuration file defines a clean or smudge
filter, there is no convenient way to override it to produce as-is
output.  Even though the configuration mechanism implements "the
last one wins" semantics, you cannot set them to an empty string and
expect them to work, as apply_filter() would try to run the empty
string as an external command and fail.  The conversion is not done,
but the function would still report a failure to convert.

Even though resetting the variable to "cat" (i.e. pass the data back
as-is and report success) is an obvious and a viable way to solve
this, it is wasteful to spawn an external process just as a
workaround.

Instead, teach apply_filter() to treat an empty string as a no-op
filter that always returns successfully its input as-is without
conversion.

4539a8982c mingw: do not bother to test funny file names
MSYS2 actually allows to create files or directories whose names contain
tabs, newlines or colors, even if plain Win32 API cannot access them.
As we are using an MSYS2 bash to run the tests, such files or
directories are created successfully, but Git itself has no chance to
work with them because it is a regular Windows program, hence limited by
the Win32 API.

With this change, on Windows otherwise failing tests in
t3300-funny-names.sh, t3600-rm.sh, t3703-add-magic-pathspec.sh,
t3902-quoted.sh, t4016-diff-quote.sh, t4135-apply-weird-filenames.sh,

75e005ec54 mingw: avoid illegal filename in t9118
On Windows' file systems, file names with trailing dots are forbidden.
The POSIX emulation layer used by Git for Windows' Subversion emulates
those file names, therefore the test adding the file would actually
succeed, but when we would ask git.exe (which does not leverage the
POSIX emulation layer) to check out the tree, it would fail.

Let's just guard the test using a filename that is illegal on Windows

The colon is used by check-ignore to separate paths from other output

It is actually not at all necessary to make the path of the global

fd318a941d mingw: work around pwd issues in the tests
In Git for Windows' SDK, the tests are run using a Bash that relies on
the POSIX emulation layer MSYS2 (itself a friendly fork of Cygwin). As
such, paths in tests can be POSIX paths. As soon as those paths are
passed to git.exe (which does *not* use the POSIX emulation layer),
those paths are converted into Windows paths, though. This happens
for command-line parameters, but not when reading, say, config variables.

To help with that, the `pwd` command is overridden to return the Windows
path of the current working directory when testing Git on Windows.

However, when talking to anything using the POSIX emulation layer, it is
really much better to use POSIX paths because Windows paths contain a
colon after the drive letter that will easily be mistaken for the common
separator in path lists.

So let's just use the $PWD variable when the POSIX path is needed.

This lets t7800-difftool.sh, t9400-git-cvsserver-server.sh,
t9402-git-cvsserver-refs.sh and t9401-git-cvsserver-crlf.sh pass in Git
for Windows' SDK.

Note: the cvsserver tests require not only the `cvs` package (install
it into Git for Windows' SDK via `pacman -S cvs`) but also the Perl
SQLite bindings (install them into Git for Windows' SDK via
`cpan DBD::SQLite`).

9d1d2b7fad git: remove an early return from save_env_before_alias()
When help.autocorrect is in effect, an attempt to auto-execute an
uniquely corrected result of a misspelt alias will result in an
irrelevant error message.  The codepath that causes this calls
save_env_before_alias() and restore_env() in handle_alias(), and
that happens twice.  A global variable orig_cwd is allocated to hold
the return value of getcwd() in save_env_before_alias(), which is
then used in restore_env() to go back to that directory and finally
free(3)'d there.

However, save_env_before_alias() is not prepared to be called twice.
It returns early when it knows it has already been called, leaving
orig_cwd undefined, which is then checked in the second call to
restore_env(), and by that time, the memory that used to hold the
contents of orig_cwd is either freed or reused to hold something
else, and this is fed to chdir(2), causing it to fail.  Even if it
did not fail (i.e. reading of the already free'd piece of memory
yielded a directory path that we can chdir(2) to), it then gets
free(3)'d.

Fix this by making sure save_env() does do the saving when called.

While at it, add a minimal test for help.autocorrect facility.

a1f32964da mingw: disable mkfifo-based tests
MSYS2 (the POSIX emulation layer used by Git for Windows' Bash) actually
has a working mkfifo. The only problem is that it is only emulating
named pipes through the MSYS2 runtime; The Win32 API has no idea about
named pipes, hence the Git executable cannot access those pipes either.

The symptom is that Git fails with a '<name>: No such file or directory'
because MSYS2 emulates named pipes through special-crafted '.lnk' files.

The solution is to tell the test suite explicitly that we cannot use
named pipes when we want to test on Windows.

This lets t4056-diff-order.sh, t9010-svn-fe.sh and t9300-fast-import.sh

fc56c7b34b mingw: accomodate t0060-path-utils for MSYS2
On Windows, there are no POSIX paths, only Windows ones (an absolute
Windows path looks like "C:\Program Files\Git\ReleaseNotes.html", under
most circumstances, forward slashes are also allowed and synonymous to
backslashes).

So when a POSIX shell (such as MSYS2's Bash, which is used by Git for
Windows to execute all those shell scripts that are part of Git) passes
a POSIX path to test-path-utils.exe (which is not POSIX-aware), the path
is translated into a Windows path. For example, /etc/profile becomes
C:/Program Files/Git/etc/profile.

This path translation poses a problem when passing the root directory as
parameter to test-path-utils.exe, as it is not well defined whether the
translated root directory should end in a slash or not. MSys1 stripped
the trailing slash, but MSYS2 does not.

Originally, the Git for Windows project patched MSYS2's runtime to
accomodate Git's regression test, but we really should do it the other
way round.

To work with both of MSys1's and MSYS2's behaviors, we simply test what
the current system does in the beginning of t0060-path-utils.sh and then
adjust the expected longest ancestor length accordingly.

It looks quite a bit tricky what we actually do in this patch: first, we
adjust the expected length for the trailing slash we did not originally
expect (subtracting one). So far, so good.

But now comes the part where things work in a surprising way: when the
expected length was 0, the prefix to match is the root directory. If the
root directory is converted into a path with a trailing slash, however,
we know that the logic in longest_ancestor_length() cannot match: to
avoid partial matches of the last directory component, it verifies that
the character after the matching prefix is a slash (but because the
slash was part of the matching prefix, the next character cannot be a
slash). So the return value is -1. Alas, this is exactly what the
expected length is after subtracting the value of $rootslash! So we skip
adding the $rootoff value in that case (and only in that case).

Directories other than the root directory are handled fine (as they are
specified without a trailing slash, something not possible for the root
directory, and MSYS2 converts them into Windows paths that also lack
trailing slashes), therefore we do not need any more special handling.

Thanks to Ray Donnelly for his patient help with this issue.

`plink.exe` a real `.exe`.
