sha1_file: allow link_alt_odb_entries to handle arbitrary repositories

Actually this also allows read_info_alternates and link_alt_odb_entry to
handle arbitrary repositories, but link_alt_odb_entries is the most
interesting function in this set of functions, hence the commit subject.

These functions span a strongly connected component in the function
graph, i.e. the recursive call chain might look like

-> link_alt_odb_entries
-> link_alt_odb_entry
-> read_info_alternates
-> link_alt_odb_entries

That is why we need to convert all these functions at the same time.

sha1_file: add repository argument to link_alt_odb_entryStefan Beller Fri, 23 Mar 2018 17:21:04 +0000 (18:21 +0100)

sha1_file: add repository argument to link_alt_odb_entry

Add a repository argument to allow the link_alt_odb_entry caller to be
more specific about which repository to act on. This is a small
mechanical change; it doesn't change the implementation to handle
repositories other than the_repository yet.

Since the implementation does not yet work with other repositories,
use a wrapper macro to enforce that the caller passes in
the_repository as the first argument. It would be more appealing to
use BUILD_ASSERT_OR_ZERO to enforce this, but that doesn't work
because it requires a compile-time constant and common compilers like
gcc 4.8.4 do not consider "r == the_repository" a compile-time
constant.

This and the following three patches add repository arguments to
link_alt_odb_entry, read_info_alternates, link_alt_odb_entries
and prepare_alt_odb. Three out of the four functions are found
in a recursive call chain, calling each other, and one of them
accesses the repositories `objectdir` (which was migrated; it
was an obvious choice) and `ignore_env` (which we need to keep in
the repository struct for clarify); hence we will pass through the
repository unlike just the object store object + the ignore_env flag.

The approximate_object_count() function maintains a rough count of
objects in a repository to estimate how long object name abbreviates
should be. Object names are scoped to a repository and the
appropriate length may differ by repository, so the object count
should not be global.

repository: introduce raw object store fieldStefan Beller Fri, 23 Mar 2018 17:20:55 +0000 (18:20 +0100)

repository: introduce raw object store field

The raw object store field will contain any objects needed for access
to objects in a given repository.

This patch introduces the raw object store and populates it with the
`objectdir`, which used to be part of the repository struct.

As the struct gains members, we'll also populate the function to clear
the memory for these members.

In a later step, we'll introduce a struct object_parser, that will
complement the object parsing in a repository struct: The raw object
parser is the layer that will provide access to raw object content,
while the higher level object parser code will parse raw objects and
keeps track of parenthood and other object relationships using 'struct
object'. For now only add the lower level to the repository struct.

repository: delete ignore_env memberNguyễn Thái Ngọc Duy Sat, 3 Mar 2018 11:35:58 +0000 (18:35 +0700)

repository: delete ignore_env member

This variable was added because the repo_set_gitdir() was created to
cover both submodule and main repos, but these two are initialized a
bit differently so ignore_env == 0 means main repo, while ignore_env
!= 0 is submodules.

Since the difference part (env variables) has been moved out of
repo_set_gitdir(), this function works the same way for both repo
types and ignore_env is not needed anymore.

getenv() is supposed to work on the main repository only. This delayed

submodule and main repositories.

It does not make sense that generic repository code contains handling
of environment variables, which are specific for the main repository
only. Refactor repo_set_gitdir() function to take $GIT_DIR and
optionally _all_ other customizable paths. These optional paths can be
NULL and will be calculated according to the default directory layout.

Note that some dead functions are left behind to reduce diff
noise. They will be deleted in the next patch.

travis-ci: don't fail if user already exists on 32 bit Linux build job

The 32 bit Linux build job runs in a Docker container, which lends
itself to running and debugging locally, too. Especially during
debugging one usually doesn't want to start with a fresh container
every time, to save time spent on installing a bunch of dependencies.
However, that doesn't work quite smootly, because the script running
in the container always creates a new user, which then must be removed
every time before subsequent executions, or the build script fails.

Make this process more convenient and don't try to create that user if
it already exists and has the right user ID in the container, so
developers don't have to bother with running a 'userdel' each time
before they run the build script.

The build job on Travis CI always starts with a fresh Docker
container, so this change doesn't make a difference there.

travis-ci: don't run the test suite as root in the 32 bit Linux build

Travis CI runs the 32 bit Linux build job in a Docker container, where
all commands are executed as root by default. Therefore, ever since
we added this build job in 88dedd5e7 (Travis: also test on 32-bit
Linux, 2017-03-05), we have a bit of code to create a user in the
container matching the ID of the host user and then to run the test
suite as this user. Matching the host user ID is important, because
otherwise the host user would have no access to any files written by
processes running in the container, notably the logs of failed tests
couldn't be included in the build job's trace log.

Alas, this piece of code never worked, because it sets the variable
holding the user name ($CI_USER) in a subshell, meaning it doesn't
have any effect by the time we get to the point to actually use the
variable to switch users with 'su'. So all this time we were running
the test suite as root.

Reorganize that piece of code in 'ci/run-linux32-build.sh' a bit to
avoid that problematic subshell and to ensure that we switch to the
right user. Furthermore, make the script's optional host user ID
option mandatory, so running the build accidentally as root will
become harder when debugging locally. If someone really wants to run
the test suite as root, whatever the reasons might be, it'll still be
possible to do so by explicitly passing '0' as host user ID.

Finally, one last catch: since commit 7e72cfcee (travis-ci: save prove
state for the 32 bit Linux build, 2017-12-27) the 'prove' test harness
has been writing its state to the Travis CI cache directory from
within the Docker container while running as root. After this patch
'prove' will run as a regular user, so in future build jobs it won't
be able overwrite a previously written, still root-owned state file,
resulting in build job failures. To resolve this we should manually
delete caches containing such root-owned files, but that would be a
hassle. Instead, work this around by changing the owner of the whole
contents of the cache directory to the host user ID.

travis-ci: don't repeat the path of the cache directory

Some of our 'ci/*' scripts repeat the name or full path of the Travis
CI cache directory, and the following patches will add new places
using that path.

Use a variable to refer to the path of the cache directory instead, so
it's hard-coded only in a single place.

Pay extra attention to the 32 bit Linux build: it runs in a Docker
container, so pass the path of the cache directory from the host to
the container in an environment variable. Note that an environment
variable passed this way is exported inside the container, therefore
its value is directly available in the 'su' snippet even though that
snippet is single quoted. Furthermore, use the variable in the
container only if it's been assigned a non-empty value, to prevent
errors when someone is running or debugging the Docker build locally,
because in that case the variable won't be set as there won't be any
Travis CI cache.

travis-ci: use 'set -e' in the 32 bit Linux build job

The script 'ci/run-linux32-build.sh' running inside the Docker
container of the 32 bit Linux build job uses an && chain to break the
build if one of the commands fails. This is problematic for two
reasons:

- The && chain is broken, because there is this in the middle:

test -z $HOST_UID || (CI_USER="ci" && useradd -u $HOST_UID $CI_USER) &&

Luckily it is broken in a way that it didn't lead to false
successes. If installing dependencies fails, then the rest of the
first && chain is skipped and execution resumes after the ||
operator. At that point $HOST_UID is still unset, causing
'useradd' to error out with "invalid user ID 'ci'", which in turn
causes the second && chain to abort the script and thus break the
build.

- All other 'ci/*' scripts use 'set -e' to break the build if one of
the commands fails. This inconsistency among these scripts is
asking for trouble: I forgot about the && chain more than once
while working on this patch series.

Enable 'set -e' for the whole script and for the commands executed
under 'su' as well.

While touching every line in the 'su' command block anyway, change
their indentation to use a tab instead of spaces.

daemon: fix length computation in newline strippingJeff King Thu, 25 Jan 2018 00:58:54 +0000 (19:58 -0500)

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).

t/lib-git-daemon: add network-protocol helpersJeff King Thu, 25 Jan 2018 00:58:19 +0000 (19:58 -0500)

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.

daemon: handle NULs in extended attribute stringJeff King Thu, 25 Jan 2018 00:56:20 +0000 (19:56 -0500)

daemon: handle NULs in extended attribute string

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 attributesJeff King Thu, 25 Jan 2018 00:56:07 +0000 (19:56 -0500)

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.

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.

the arguments passed so they make a bit more sense - for instance
cherry-pick currently passes different arguments depending on whether

changed things so that when squashing rebase would pass 'squash' as
the argument to the hook but that has been lost.

I think that it would make more sense to pass 'message' for revert and
cherry-pick -x/-s (i.e. cases where there is a new message or the
current message in modified by the command), 'squash' when squashing
with a new message and 'commit HEAD/CHERRY_PICK_HEAD'

In a0a967568e ("update-index --split-index: do not split if $GIT_DIR is

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.

Use MOVE_ARRAYSZEDER Gábor Mon, 22 Jan 2018 17:50:09 +0000 (18:50 +0100)

Use MOVE_ARRAY

Use the helper macro MOVE_ARRAY to move arrays. This is shorter and
safer, as it automatically infers the size of elements.

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.
