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.

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.

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.

read-cache: don't write index twice if we can't write shared index
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.

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.

Split index mode only has a few dedicated tests, but as the index is
involved in nearly every git operation, this doesn't quite cover all the
ways repositories with split index can break. To use split index mode
throughout the test suite a GIT_TEST_SPLIT_INDEX environment variable
can be set, which makes git split the index at random and thus
excercises the functionality much more thoroughly.
As this is not turned on by default, it is not executed nearly as often
as the test suite is run, so occationally breakages slip through. Try
to counteract that by running the test suite with GIT_TEST_SPLIT_INDEX
mode turned on on travis.
To avoid using too many cycles on travis only run split index mode in
the linux-gcc target only. The Linux build was chosen over the Mac OS
builds because it tends to be much faster to complete.
The linux gcc build was chosen over the linux clang build because the
linux clang build is the fastest build, so it can serve as an early
indicator if something is broken and we want to avoid spending the extra
cycles of running the test suite twice for that.

split-index: don't write cache tree with null oid entries
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.

read-cache: fix reading the shared index for other repos
read_index_from() takes a path argument for the location of the index
file. For reading the shared index in split index mode however it just
ignores that path argument, and reads it from the gitdir of the current
repository.
This works as long as an index in the_repository is read. Once that
changes, such as when we read the index of a submodule, or of a
different working tree than the current one, the gitdir of
the_repository will no longer contain the appropriate shared index,
and git will fail to read it.
For example t3007-ls-files-recurse-submodules.sh was broken with
GIT_TEST_SPLIT_INDEX set in 188dce131f ("ls-files: use repository
object", 2017-06-22), and t7814-grep-recurse-submodules.sh was also
broken in a similar manner, probably by introducing struct repository
there, although I didn't track down the exact commit for that.
be489d02d2 ("revision.c: --indexed-objects add objects from all
worktrees", 2017-08-23) breaks with split index mode in a similar
manner, not erroring out when it can't read the index, but instead
carrying on with pruning, without taking the index of the worktree into
account.
Fix this by passing an additional gitdir parameter to read_index_from,
to indicate where it should look for and read the shared index from.
read_cache_from() defaults to using the gitdir of the_repository. As it
is mostly a convenience macro, having to pass get_git_dir() for every
call seems overkill, and if necessary users can have more control by
using read_index_from().

path. But that is not the case in Git for Windows' test suite, there are

merge-recursive: do not look at the index during recursive merge
When merging another branch into ours, if their tree is the same as
the common ancestor's, we can declare that our tree represents the
result of three-way merge. In such a case, the recursive merge
backend incorrectly used to create a commit out of our index, even
when the index has changes.
A recent fix attempted to prevent this by adding a comparison
between "our" tree and the index, but forgot that this check must be
restricted only to the outermost merge. Inner merges performed by
the recursive backend across merge bases are by definition made from
scratch without having any local changes added to the index. The
call to index_has_changes() during an inner merge is working on the
index that has no relation to the merge being performed, preventing
legitimate merges from getting carried out.
Fix it by limiting the check to the outermost merge.

Ever since we started building and testing Git on Travis CI (522354d70
(Add Travis CI support, 2015-11-27)), we build Git in the
'before_script' phase and run the test suite in the 'script' phase
(except in the later introduced 32 bit Linux and Windows build jobs,
where we build in the 'script' phase').
Contrarily, the Travis CI practice is to build and test in the
'script' phase; indeed Travis CI's default build command for the
'script' phase of C/C++ projects is:
./configure && make && make test
The reason why Travis CI does it this way and why it's a better
approach than ours lies in how unsuccessful build jobs are
categorized. After something went wrong in a build job, its state can
be:
- 'failed', if a command in the 'script' phase returned an error.
This is indicated by a red 'X' on the Travis CI web interface.
- 'errored', if a command in the 'before_install', 'install', or
'before_script' phase returned an error, or the build job exceeded
the time limit. This is shown as a red '!' on the web interface.
This makes it easier, both for humans looking at the Travis CI web
interface and for automated tools querying the Travis CI API, to
decide when an unsuccessful build is our responsibility requiring
human attention, i.e. when a build job 'failed' because of a compiler
error or a test failure, and when it's caused by something beyond our
control and might be fixed by restarting the build job, e.g. when a
build job 'errored' because a dependency couldn't be installed due to
a temporary network error or because the OSX build job exceeded its
time limit.
The drawback of building Git in the 'before_script' phase is that one
has to check the trace log of all 'errored' build jobs, too, to see
what caused the error, as it might have been caused by a compiler
error. This requires additional clicks and page loads on the web
interface and additional complexity and API requests in automated
tools.
Therefore, move building Git from the 'before_script' phase to the
'script' phase, updating the script's name accordingly as well.
'ci/run-builds.sh' now becomes basically empty, remove it. Several of
our build job configurations override our default 'before_script' to
do nothing; with this change our default 'before_script' won't do
anything, either, so remove those overriding directives as well.

stash: don't delete untracked files that match pathspec
Currently when 'git stash push -- <pathspec>' is used, untracked files
that match the pathspec will be deleted, even though they do not end up
in a stash anywhere.
This is because the original commit introducing the pathspec feature in
git stash push (df6bba0937 ("stash: teach 'push' (and 'create_stash') to
honor pathspec", 2017-02-28)) used the sequence of 'git reset <pathspec>
&& git ls-files --modified <pathspec> | git checkout-index && git clean
<pathspec>'.
The intention was to emulate what 'git reset --hard -- <pathspec>' would
do. The call to 'git clean' was supposed to clean up the files that
were unstaged by 'git reset'. This would work fine if the pathspec
doesn't match any files that were untracked before 'git stash push --
<pathspec>'. However if <pathspec> matches a file that was untracked
before invoking the 'stash' command, all untracked files matching the
pathspec would inadvertently be deleted as well, even though they
wouldn't end up in the stash, and are therefore lost.
This behaviour was never what was intended, only blobs that also end up
in the stash should be reset to their state in HEAD, previously
untracked files should be left alone.
To achieve this, first match what's in the index and what's in the
working tree by adding all changes to the index, ask diff-index what
changed between HEAD and the current index, and then apply that patch in
reverse to get rid of the changes, which includes removal of added
files and resurrection of removed files.

* js/sequencer-cleanups:
sequencer: do not invent whitespace when transforming OIDs
sequencer: report when noop has an argument
sequencer: remove superfluous conditional
sequencer: strip bogus LF at end of error messages
rebase: do not continue when the todo list generation failed
"git merge -s recursive" did not correctly abort when the index is
dirty, if the merged tree happened to be the same as the current
HEAD, which has been fixed.

submodule: submodule_move_head omits old argument in forced case
When using hard reset or forced checkout with the option to recurse into
submodules, the submodules need to be reset, too.
It turns out that we need to omit the duplicate old argument to read-tree
in all forced cases to omit the 2 way merge and use the more assertive
behavior of reading the specific new tree into the index and updating
the working tree.

When there is a one way merge, each submodule needs to be one way merged
as well, if we're asked to recurse into submodules.
In case of a submodule, check if it is up-to-date, otherwise set the
flag CE_UPDATE, which will trigger an update of it in the phase updating
the tree later.

t/lib-submodule-update.sh: fix test ignoring ignored files in submodules
It turns out that the test replacing a submodule with a file with
the submodule containing an ignored file is incorrectly titled,
because the test put the file in place, but never ignored that file.
When having an untracked file Instead of an ignored file in the
submodule, git should refuse to remove the submodule, but that is
a bug in the implementation of recursing into submodules, such that
the test just passed, removing the untracked file.
Fix the test first; in a later patch we'll fix gits behavior,
that will make sure untracked files are not deleted.

It has been reported that strategy arguments are not passed to `git
merge` correctly when rebasing interactively, preserving merges.
The reason is that the strategy arguments are already quoted, and then
quoted again.
