shortlog: skip format/parse roundtrip for internal traversal
The original git-shortlog command parsed the output of
git-log, and the logic went something like this:
1. Read stdin looking for "author" lines.
2. Parse the identity into its name/email bits.
3. Apply mailmap to the name/email.
4. Reformat the identity into a single buffer that is our
"key" for grouping entries (either a name by default,
or "name <email>" if --email was given).
The first part happens in read_from_stdin(), and the other
three steps are part of insert_one_record().
When we do an internal traversal, we just swap out the stdin
read in step 1 for reading the commit objects ourselves.
Prior to 2db6b83d18 (shortlog: replace hand-parsing of
author with pretty-printer, 2016-01-18), that made sense; we
still had to parse the ident in the commit message.
But after that commit, we use pretty.c's "%an <%ae>" to get
the author ident (for simplicity). Which means that the
pretty printer is doing a parse/format under the hood, and
then we parse the result, apply the mailmap, and format the
result again.
Instead, we can just ask pretty.c to do all of those steps
for us (including the mailmap via "%aN <%aE>", and not
formatting the address when --email is missing).
And then we can push steps 2-4 into read_from_stdin(). This
speeds up "git shortlog -ns" on linux.git by about 3%, and
eliminates a leak in insert_one_record() of the namemailbuf
strbuf.

slashes at the beginning.
This may need to be heavily tested before it gets unleashed to the

may be unexpected fallouts in the path normalization.

If we get a repo path like "-repo.git", we may try to invoke

upload-pack will interpret it as a set of bogus options. But
let's reject this before we even run the sub-program, since
we would not want to allow any mischief with repo names that
actually are real command-line options.
You can still ask for such a path via git-daemon, but there's no
security problem there, because git-daemon enters the repo itself
and then passes "." on the command line.

connect: reject dashed arguments for proxy commands
If you have a GIT_PROXY_COMMAND configured, we will run it
with the host/port on the command-line. If a URL contains a
mischievous host like "--foo", we don't know how the proxy
command may handle it. It's likely to break, but it may also
do something dangerous and unwanted (technically it could
even do something useful, but that seems unlikely).
We should err on the side of caution and reject this before
we even run the command.
The hostname check matches the one we do in a similar
circumstance for ssh. The port check is not present for ssh,
but there it's not necessary because the syntax is "-p
<port>", and there's no ambiguity on the parsing side.
It's not clear whether you can actually get a negative port
to the proxy here or not. Doing:
git fetch git://remote:-1234/repo.git
keeps the "-1234" as part of the hostname, with the default
port of 9418. But it's a good idea to keep this check close
to the point of running the command to make it clear that
there's no way to circumvent it (and at worst it serves as a
belt-and-suspenders check).

connect: reject ssh hostname that begins with a dash
When commands like "git fetch" talk with ssh://$rest_of_URL/, the
code splits $rest_of_URL into components like host, port, etc., and
then spawns the underlying "ssh" program by formulating argv[] array
that has:
- the path to ssh command taken from GIT_SSH_COMMAND, etc.
- dashed options like '-batch' (for Tortoise), '-p <port>' as
needed.
- ssh_host, which is supposed to be the hostname parsed out of
$rest_of_URL.
- then the command to be run on the other side, e.g. git
upload-pack.
If the ssh_host ends up getting '-<anything>', the argv[] that is
used to spawn the command becomes something like:
which obviously is bogus, but depending on the actual value of
"<anything>", will make "ssh" parse and use it as an option.
Prevent this by forbidding ssh_host that begins with a "-".

t/lib-proto-disable: restore protocol.allow after config tests
The tests for protocol.allow actually set that variable in
the on-disk config, run a series of tests, and then never
clean up after themselves. This means that whatever tests we
run after have protocol.allow=never, which may influence
their results.
In most cases we either exit after running these tests, or
do another round of test_proto(). In the latter case, this happens to
work because:
1. Tests of the GIT_ALLOW_PROTOCOL environment variable
override the config.
2. Tests of the specific config "protocol.foo.allow"
override the protocol.allow config.
3. The next round of protocol.allow tests start off by
setting the config to a known value.
However, it's a land-mine waiting to trap somebody adding
new tests to one of the t581x test scripts. Let's make sure
we clean up after ourselves.

credential-cache: interpret an ECONNRESET as an EOF
Since commit 612c49e94d ("credential-cache: add tests for XDG
functionality", 17-03-2017), the cygwin build has been failing all the
new tests added by that commit. In particular, the 'git credential-cache
exit' command, as part of the test cleanup code, has been die-ing with
the message:
fatal: read error from cache daemon: Connection reset by peer
As this git command is part of an && chain in a 'test_when_finished'
call, the remaining test cleanup is not happening, so practically all
remaining tests fail due to the unexpected presence of various socket
files and directories.
A simple means of getting the tests to pass, is to simply ignore the
failure of 'git credential-cache exit' command and make sure all test
cleanup is done. For example, the diff for test #12 would look like:
... and so on for all remaining tests. While this does indeed make all
tests pass, it is not really a solution.
As an aside, while looking to debug this issue, I added the '--debug'
option to the invocation of the 'git-credential-cache--daemon' child
process (see the spawn_daemon() function). This not only fixed the tests,
but also stopped git-credential-cache exiting with a failure. Since the
only effect of passing '--debug' was to suppress the redirection of stderr
to the bit-bucket (/dev/null), I have no idea why this seems to fix the
protocol interaction between git and git-credential-cache--daemon. (I
did think that maybe it was a timing issue, so I tried sleeping before
reading from the daemon on Linux, but that only slowed down the tests!)
All descriptions of the "Connection reset by peer" error, that I could
find, say that the peer had destroyed the connection before the client
attempted to perform I/O on the connection. Since the daemon does not
respond to an "exit" message from the client, it just closes the socket
and deletes the socket file (via the atexit handler), it seems that the
expected result is for the client to receive an EOF. Indeed, this is
exactly what seems to be happening on Linux. Also a comment in
credential-cache--daemon.c reads:
else if (!strcmp(action.buf, "exit")) {
/*
* It's important that we clean up our socket first, and then
* signal the client only once we have finished the cleanup.
* Calling exit() directly does this, because we clean up in
* our atexit() handler, and then signal the client when our
* process actually ends, which closes the socket and gives
* them EOF.
*/
exit(0);
}
On cygwin this is not the case, at least when not passing --debug to the
daemon, and the read following the "exit" gets an error with errno set
to ECONNRESET.
In order to suppress the fatal exit in this case, check the read error
for an ECONNRESET and return as if no data was read from the daemon.
This effectively converts an ECONNRESET into an EOF.

sub-process: refactor handshake to common function
Refactor, into a common function, the version and capability negotiation
done when invoking a long-running process as a clean or smudge filter.
This will be useful for other Git code that needs to interact similarly
with a long-running process.
As you can see in the change to t0021, this commit changes the error
message reported when the long-running process does not introduce itself
with the expected "server"-terminated line. Originally, the error
message reports that the filter "does not support filter protocol
version 2", differentiating between the old single-file filter protocol
and the new multi-file filter protocol - I have updated it to something
more generic and useful.

However, with MSys2, we no longer need that because we have a proper

When attempting to blame a non-existing path, git should show an error
message like this:
$ git blame e83c51633 -- nonexisting-file
fatal: no such path nonexisting-file in e83c51633
Since the recent commit 835c49f7d (blame: rework methods that
determine 'final' commit, 2017-05-24) the revision name is either
missing or some scrambled characters are shown instead. The reason is
that the revision name must be duplicated, because it is invalidated
when the pending objects array is cleared in the meantime, but this
commit dropped the duplication.
Restore the duplication of the revision name in the affected functions
(find_single_final() and find_single_initial()).
