63b1a175ee t: make 'test_i18ngrep' more informative on failure
When 'test_i18ngrep' can't find the expected pattern, it exits
completely silently; when its negated form does find the pattern that
shouldn't be there, it prints the matching line(s) but otherwise exits
without any error message.  This leaves the developer puzzled about
what could have gone wrong.

Make 'test_i18ngrep' more informative on failure by printing an error
message including the invoked 'grep' command and the contents of the
file it had to scan through.

Note that this "dump the scanned file" part is not quite perfect, as
it dumps only the file specified as the function's last positional
parameter, thus assuming that there is only a single file parameter.
I think that's a reasonable assumption to make, one that holds true in
the current code base.  And even if someone were to scan multiple
files at once in the future, the worst thing that could happen is that
the verbose error message won't include the contents of all those
files, only the last one.  Alas, we can't really do any better than
this, because checking whether the other positional parameters match a
filename can result in false positives: 't3400-rebase.sh' and
't3404-rebase-interactive.sh' contain one test each, where the
'test_i18ngrep's pattern verbatimly matches a file in the trash
directory.

fd29d7b9d7 t: validate 'test_i18ngrep's parameters
Some of the previous patches in this series fixed bogus
'test_i18ngrep' invocations:

  - Two invocations where the tested git command's standard output is
    directly piped into 'test_i18ngrep'.  While convenient, this is an
    antipattern, because the pipe hides the git command's exit code,
    and the test could continue even if the command exited with error.

  - Two invocations that had neither a filename parameter nor anything
    piped into their standard input, yet both managed to remain
    unnoticed for years.  A third similarly bogus invocation is
    currently lurking in 'pu' for a couple of weeks now.

Prevent similar mistakes in the future by validating 'test_i18ngrep's
parameters requiring that

  - The last parameter names an existing file to be read, effectively
    forbidding piping into 'test_i18ngrep'.

    Note that this change will also forbid cases where 'test_i18ngrep'
    would legitimately read its standard input, e.g. when its standard
    input is redirected from a file, or when a git command's standard
    output is first written to an intermediate file, which is then
    preprocessed by a non-git command before the results are piped
    into 'test_i18ngrep'.  See two of the previous patches for the
    only such cases we had in our test suite.  However, reliably
    preventing the piping antipattern is arguably more important than
    supporting these cases, which can be easily worked around by
    opening the file directly or using an intermediate file anyway.

  - There are at least two parameters, not including the optional '!'
    to negate the pattern.  This ought to catch corner cases when
    'test_i18ngrep' looks for the name of an existing file on its
    standard input; the above check would miss this case becase the
    filename as pattern would be the last parameter.

    Note that this is not quite perfect, as it doesn't account for any
    'grep --options' given as parameters.  However, doing so would be
    far too complicated, considering that patterns can start with
    dashes as well, and in the majority of the cases we don't use any
    such options anyway.

927c1a643a t5510: consolidate 'grep' and 'test_i18ngrep' patterns
One of the tests in 't5510-fetch.sh' checks the output of 'git fetch'
using 'test_i18ngrep', and while doing so it prefilters the output
with 'grep' before piping the result into 'test_i18ngrep'.

This prefiltering is unnecessary, with the appropriate pattern
'test_i18ngrep' can do it all by itself.  Furthermore, piping data
into 'test_i18ngrep' will interfere with the linting that will be
added in a later patch.

a4ca4553e0 t5812: add 'test_i18ngrep's missing filename parameter
The second 'test_i18ngrep' invocation in the test 'curl redirects
respect whitelist' is missing its filename parameter.  This has
remained unnoticed since its introduction in f4113cac0 (http: limit
redirection to protocol-whitelist, 2015-09-22), because it would only
cause the test to fail if Git was built with a sufficiently old
libcurl version.  The test's two ||-chained 'test_i18ngrep'
invocations are supposed to check that either one of the two patterns
is present in 'git clone's error message.  As it happens, the first
invocation covers the error message from any reasonably up-to-date
libcurl, thus the second invocation, the one without the filename
parameter, isn't executed at all.  Apparently no one has run the test
suite's httpd tests with such an old libcurl in the last 2+ years, or
at least they haven't bothered to notify us about the failed test.

Fix this by consolidating the two patterns into a single extended
regexp, eliminating the need for an ||-chained second 'test_i18ngrep'
invocation.

ed15e58efe daemon: fix length computation in newline stripping
When git-daemon gets a pktline request, we strip off any
trailing newline, replacing it with a NUL. Clients prior to
5ad312bede (in git v1.4.0) would send:

  git-upload-pack repo.git\n

and we need to strip it off to understand their request.
After 5ad312bede, we send the host attribute but no newline,
like:

  git-upload-pack repo.git\0host=example.com\0

Both of these are parsed correctly by git-daemon. But if
some client were to combine the two:

  git-upload-pack repo.git\n\0host=example.com\0

we don't parse it correctly. The problem is that we use the
"len" variable to record the position of the NUL separator,
but then decrement it when we strip the newline. So we start
with:

  git-upload-pack repo.git\n\0host=example.com\0
                             ^-- len

and end up with:

  git-upload-pack repo.git\0\0host=example.com\0
                           ^-- len

This is arguably correct, since "len" tells us the length of
the initial string, but we don't actually use it for that.
What we do use it for is finding the offset of the extended
attributes; they used to be at len+1, but are now at len+2.

We can solve that by just leaving "len" where it is. We
don't have to care about the length of the shortened string,
since we just treat it like a C string.

No version of Git ever produced such a string, but it seems
like the daemon code meant to handle this case (and it seems
like a reasonable thing for somebody to do in a 3rd-party
implementation).

4414a15002 t/lib-git-daemon: add network-protocol helpers
All of our git-protocol tests rely on invoking the client
and having it make a request of a server. That gives a nice
real-world test of how the two behave together, but it
doesn't leave any room for testing how a server might react
to _other_ clients.

Let's add a few test helper functions which can be used to
manually conduct a git-protocol conversation with a remote
git-daemon:

  1. To connect to a remote git-daemon, we need something
     like "netcat". But not everybody will have netcat. And
     even if they do, the behavior with respect to
     half-duplex shutdowns is not portable (openbsd netcat
     has "-N", with others you must rely on "-q 1", which is
     racy).

     Here we provide a "fake_nc" that is capable of doing
     a client-side netcat, with sane half-duplex semantics.
     It relies on perl's IO::Socket::INET. That's been in
     the base distribution since 5.6.0, so it's probably
     available everywhere. But just to be on the safe side,
     we'll add a prereq.

  2. To help tests speak and read pktline, this patch adds
     packetize() and depacketize() functions.

I've put fake_nc() into lib-git-daemon.sh, since that's
really the only server where we'd need to use a network
socket.  Whereas the pktline helpers may be of more general
use, so I've added them to test-lib-functions.sh. Programs
like upload-pack speak pktline, but can talk directly over
stdio without a network socket.

NUL, we try to write those attributes to the log. We do so
with a "%s" format specifier, which will only show
characters up to the first NUL.

That's enough for printing a "host=" specifier. But since
dfe422d04d (daemon: recognize hidden request arguments,
2017-10-16) we may have another NUL, followed by protocol
parameters, and those are not logged at all.

Let's cut out the attempt to show the whole string, and
instead log when we parse individual attributes. We could
leave the "extended attributes (%d bytes) exist" part of the
log, which in theory could alert us to attributes that fail
to parse. But anything we don't parse as a "host=" parameter
gets blindly added to the "protocol" attribute, so we'd see
it in that part of the log.

19136be3f8 daemon: fix off-by-one in logging extended attributes
If receive a request like:

  git-upload-pack /foo.git\0host=localhost

we mark the offset of the NUL byte as "len", and then log
the bytes after the NUL with a "%.*s" placeholder, using
"pktlen - len" as the length, and "line + len + 1" as the
start of the string.

This is off-by-one, since the start of the string skips past
the separating NUL byte, but the adjusted length includes
it. Fortunately this doesn't actually read past the end of
the buffer, since "%.*s" will stop when it hits a NUL. And
regardless of what is in the buffer, packet_read() will
always add an extra NUL terminator for safety.

As an aside, the git.git client sends an extra NUL after a
"host" field, too, so we'd generally hit that one first, not
the one added by packet_read(). You can see this in the test
output which reports 15 bytes, even though the string has
only 14 bytes of visible data. But the point is that even a
client sending unusual data could not get us to read past
the end of the buffer, so this is purely a cosmetic fix.

314a73d658 t/lib-git-daemon: record daemon log
When we start git-daemon for our tests, we send its stderr
log stream to a named pipe. We synchronously read the first
line to make sure that the daemon started, and then dump the
rest to descriptor 4. This is handy for debugging test
output with "--verbose", but the tests themselves can't
access the log data.

Let's dump the log into a file, as well, so that future
tests can check the log. There are a few subtleties worth
calling out here:

  - we'll continue to send output to descriptor 4 for
    viewing/debugging, which would imply swapping out "cat"
    for "tee". But we want to ensure that there's no
    buffering, and "tee" doesn't have a standard way to
    ask for that. So we'll use a shell loop around "read"
    and "printf" instead. That ensures that after a request
    has been served, the matching log entries will have made
    it to the file.

  - the existing first-line shell loop used read/echo. We'll
    switch to consistently using "read -r" and "printf" to
    relay data as faithfully as possible.

  - we open the logfile for append, rather than just output.
    That makes it OK for tests to truncate the logfile
    without restarting the daemon (the OS will atomically
    seek to the end of the file when outputting each line).
    That allows tests to look at the log without worrying
    about pollution from earlier tests.

02adf84ab8 t5570: use ls-remote instead of clone for interp tests
We don't actually care about the clone operation here; we
just want to know if we were able to actually contact the
remote repository. Using ls-remote does that more
efficiently, and without us having to worry about managing
the tmp.git directory.

b6947af229 t5601-clone: test case-conflicting files on case-insensitive filesystem
A recently introduced regression caused a segfault at clone time on
case-insensitive filesystems when filenames differing only in case are
present. This bug has already been fixed (repository: pre-initialize
hash algo pointer, 2018-01-18), but it's not the first time similar
problems have arisen. Therefore, introduce a test to catch this case and
protect against future regressions.

e26f7f19b6 repository: pre-initialize hash algo pointer
There are various git subcommands (among them, clone) which don't set up
the repository (that is, they lack RUN_SETUP or RUN_SETUP_GENTLY) but
end up needing to have information about the hash algorithm in use.
Because the hash algorithm is part of struct repository and it's only
initialized in repository setup, we can end up dereferencing a NULL
pointer in some cases if we call one of these subcommands and look up
the empty blob or empty tree values.

A "git clone" of a project that has two paths that differ only in
case suffers from this if it is run on a case insensitive platform.
When the command attempts to check out one of these two paths after
checking out the other one, the checkout codepath needs to see if
the version that is already on the filesystem (which should not
happen if the FS were case sensitive) is dirty, and it needs to
exercise the hashing code at that point.

In the future, we can add a command line option for this or read it
from the configuration, but until we're ready to expose that
functionality to the user, simply initialize the repository
structure to use the current hash algorithm, SHA-1.

Running git clone --single-branch --mirror -b TAGNAME previously
triggered the following error message:

	fatal: multiple updates for ref 'refs/tags/TAGNAME' not allowed.

This error condition is handled in files_initial_transaction_commit().

42c7f7ff9 ("commit_packed_refs(): remove call to `packed_refs_unlock()`", 2017-06-23)
introduced incorrect unlocking in the error path of this function,
which changes the error message to

	fatal: BUG: packed_refs_unlock() called when not locked

Move the call to packed_refs_unlock() above the "cleanup:" label
since the unlocking should only be done in the last error path.
