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.

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.

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

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.

remained unnoticed since its introduction in e304aeba2 (t5541: test
more combinations of --progress, 2012-05-01), because that
'test_i18ngrep' is supposed to check that the given pattern is not

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).

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.

If we receive a request with extended attributes after the
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.

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.

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.

In a0a967568e ("update-index --split-index: do not split if $GIT_DIR is
read only", 2014-06-13), we tried to make sure we can still write an
index, even if the shared index can not be written.
We did so by just calling 'do_write_locked_index()' just before
'write_shared_index()'. 'do_write_locked_index()' always at least
closes the tempfile nowadays, and used to close or commit the lockfile
if COMMIT_LOCK or CLOSE_LOCK were given at the time this feature was
introduced. COMMIT_LOCK or CLOSE_LOCK is passed in by most callers of
'write_locked_index()'.
After calling 'write_shared_index()', we call 'write_split_index()',
which calls 'do_write_locked_index()' again, which then tries to use the
closed lockfile again, but in fact fails to do so as it's already
closed. This eventually leads to a segfault.
Make sure to write the main index only once.

In a96d3cc3f6 ("cache-tree: reject entries with null sha1", 2017-04-21)
we made sure that broken cache entries do not get propagated to new
trees. Part of that was making sure not to re-use an existing cache
tree that includes a null oid.
It did so by dropping the cache tree in 'do_write_index()' if one of
the entries contains a null oid. In split index mode however, there
are two invocations to 'do_write_index()', one for the shared index
and one for the split index. The cache tree is only written once, to
the split index.
As we only loop through the elements that are effectively being
written by the current invocation, that may not include the entry with
a null oid in the split index (when it is already written to the
shared index), where we write the cache tree. Therefore in split
index mode we may still end up writing the cache tree, even though
there is an entry with a null oid in the index.
Fix this by checking for null oids in prepare_to_write_split_index,
where we loop the entries of the shared index as well as the entries for
the split index.
This fixes t7009 with GIT_TEST_SPLIT_INDEX. Also add a new test that's
more specifically showing the problem.

For 'add -i' and 'add -p', the only action we can take on a dirty
submodule entry is update the index with a new value from its HEAD. The
content changes inside (from its own index, untracked files...) do not
matter, at least until 'git add -i' learns about launching a new
interactive add session inside a submodule.
Ignore all other submodules changes except HEAD. This reduces the number
of entries the user has to check through in 'git add -i', and the number
of 'no' they have to answer to 'git add -p' when dirty submodules are
present.
