1c96642326 sparse: allow '{ 0 }' to be used without warnings
In standard C, '{ 0 }' can be used as an universal zero-initializer.
However, Sparse complains if this is used on a type where the first
member (possibly nested) is a pointer since Sparse purposely wants
to warn when '0' is used to initialize a pointer type.

Legitimaly, it's desirable to be able to use '{ 0 }' as an idiom
without these warnings [1,2]. To allow this, an option have now
been added to Sparse:
    537e3e2dae univ-init: conditionally accept { 0 } without warnings

So, add this option to the SPARSE_FLAGS variable.

Note: The option have just been added to Sparse. So, to benefit
      now from this patch it's needed to use the latest Sparse
      source from kernel.org. The option will simply be ignored
      by older versions of Sparse.

b0df0c16ea stateless-connect: send response end packet
Currently, remote-curl acts as a proxy and blindly forwards packets
between an HTTP server and fetch-pack. In the case of a stateless RPC
connection where the connection is terminated before the transaction is
complete, remote-curl will blindly forward the packets before waiting on
more input from fetch-pack. Meanwhile, fetch-pack will read the
transaction and continue reading, expecting more input to continue the
transaction. This results in a deadlock between the two processes.

This can be seen in the following command which does not terminate:

	$ git -c protocol.version=2 clone https://github.com/git/git.git --shallow-since=20151012
	Cloning into 'git'...

whereas the v1 version does terminate as expected:

	$ git -c protocol.version=1 clone https://github.com/git/git.git --shallow-since=20151012
	Cloning into 'git'...
	fatal: the remote end hung up unexpectedly

Instead of blindly forwarding packets, make remote-curl insert a
response end packet after proxying the responses from the remote server
when using stateless_connect(). On the RPC client side, ensure that each
response ends as described.

A separate control packet is chosen because we need to be able to
differentiate between what the remote server sends and remote-curl's
control packets. By ensuring in the remote-curl code that a server
cannot send response end packets, we prevent a malicious server from
being able to perform a denial of service attack in which they spoof a
response end packet and cause the described deadlock to happen.

0181b600a6 pkt-line: define PACKET_READ_RESPONSE_END
In a future commit, we will use PACKET_READ_RESPONSE_END to separate
messages proxied by remote-curl. To prepare for this, add the
PACKET_READ_RESPONSE_END enum value.

In switch statements that need a case added, die() or BUG() when a
PACKET_READ_RESPONSE_END is unexpected. Otherwise, mirror how
PACKET_READ_DELIM is implemented (especially in cases where packets are
being forwarded).

74b082ad34 remote-curl: error on incomplete packet
Currently, remote-curl acts as a proxy and blindly forwards packets
between an HTTP server and fetch-pack. In the case of a stateless RPC
connection where the connection is terminated with a partially written
packet, remote-curl will blindly send the partially written packet
before waiting on more input from fetch-pack. Meanwhile, fetch-pack will
read the partial packet and continue reading, expecting more input. This
results in a deadlock between the two processes.

For a stateless connection, inspect packets before sending them and
error out if a packet line packet is incomplete.

d63ae31962 t5608: avoid say() and use "skip_all" instead for consistency
Printing a message directly to stdout could affect TAP processing
and is not really needed, as there is a standard way to skip all
tests that could be used instead, while printing an equivalent
message.

While at it; update the message to better reflect that since
a85efb5985 (t5608-clone-2gb.sh: turn GIT_TEST_CLONE_2GB into a bool,
2019-11-22), the enabling variable should be a recognized boolean
(ex: true, false, 1, 0) and get rid of the prerequisite that used
to guard all the tests, since "skip_all" is just much faster and
idempotent.

bb2198fb91 checkout: improve error messages for -b with extra argument
When we try to create a branch "foo" based on "origin/master" and give
git commit -b an extra unsupported argument "bar", it confusingly
reports:

   $ git checkout -b foo origin/master bar
   fatal: 'bar' is not a commit and a branch 'foo' cannot be created from it

   $ git checkout --track -b foo origin/master bar
   fatal: 'bar' is not a commit and a branch 'foo' cannot be created from it

That's wrong, because it very well understands that "origin/master" is
supposed to be the start point for the new branch and not "bar".  Check
if we got a commit and show more fitting messages in that case instead:

   $ git checkout -b foo origin/master bar
   fatal: Cannot update paths and switch to branch 'foo' at the same time.

   $ git checkout --track -b foo origin/master bar
   fatal: '--track' cannot be used with updating paths

16ab794b82 checkout: add tests for -b and --track
Test git checkout -b with and without --track and demonstrate unexpected
error messages when it's given an extra (i.e. unsupported) path
argument.  In both cases it reports:

   $ git checkout -b foo origin/master bar
   fatal: 'bar' is not a commit and a branch 'foo' cannot be created from it

The problem is that the start point we gave for the new branch is
"origin/master" and "bar" is just some extra argument -- it could even
be a valid commit, which would make the message even more confusing.  We
have more fitting error messages in git commit, but get confused; use
the text of the rights ones in the tests.

4d9005ff5d bisect--helper: avoid segfault with bad syntax in start --term-*
06f5608c14 (bisect--helper: `bisect_start` shell function partially in C,
2019-01-02) adds a lax parser for `git bisect start` which could result
in a segfault under a bad syntax call for start with custom terms.

Detect if there are enough arguments left in the command line to use for
--term-{old,good,new,bad} and abort with the same syntax error the original
implementation will show if not.

While at it, remove an unnecessary (and incomplete) check for unknown
arguments and make sure to add a test to avoid regressions.

fffd0cf520 completion: don't override given stash subcommand with -p
df70b190 (completion: make stash -p and alias for stash push -p,
2018-04-20) wanted to make sure "git stash -p <TAB>" offers the same
completion as "git stash push -p <TAB>", but it did so by forcing the
$subcommand to be "push" whenever then "-p" option is found on the
command line.

This harms any subcommand that can take the "-p" option---even when the
subcommand is explicitly given, e.g. "git stash show -p", the code added
by the change would overwrite the $subcommand the user gave us.

Fix it by making sure that the defaulting to "push" happens only when
there is no $subcommand given yet.

fe747043dc fsck: detect more in-tree d/f conflicts
If the conflict candidate file name from the top of the stack is not a
prefix of the current candiate directory then we can discard it as no
matching directory can come up later.  But we are not done checking the
candidate directory -- the stack might still hold a matching file name,
so stay in the loop and check the next candidate file name.

fc12aa7bfd t1450: increase test coverage of in-tree d/f detection
Exercise the case of putting a conflict candidate file name back on the
stack because a matching directory might yet come up later.

Do that by factoring out the test code into a function to allow for more
concise notation in the form of parameters indicating names of trees
(with trailing slash) and blobs (without trailing slash) in no
particular order (they are sorted by git mktree).  Then add the new test
case as a second function call.

81861288a9 builtin/checkout: simplify metadata initialization
When we call init_checkout_metadata in reset_tree, we want to pass the
object ID of the commit in question so that it can be passed to filters,
or if there is no commit, the tree.  We anticipated this latter case,
which can occur elsewhere in the checkout code, but it cannot occur
here.  The only case in which we do not have a commit object is when
invoking git switch with --orphan.  Moreover, we can only hit this code
path without a commit object additionally with either --force or
--discard-changes.

In such a case, there is no point initializing the checkout metadata
with a commit or tree because (a) there is no commit, only the empty
tree, and (b) we will never use the data, since no files will be smudged
when checking out a branch with no files.  Pass the all-zeros object ID
in this case, since we just need some value which is a valid pointer.

3697caf4b9 config: let feature.experimental imply protocol.version=2
Git 2.26 used protocol v2 as its default protocol, but soon after
release, users noticed that the protocol v2 negotiation code was prone
to fail when fetching from some remotes that are far ahead of others
(such as linux-next.git versus Linus's linux.git).  That has been
fixed by 0b07eecf6e (Merge branch 'jt/v2-fetch-nego-fix',
2020-05-01), but to be cautious, we are using protocol v0 as the
default in 2.27 to buy some time for any other unanticipated issues to
surface.

To that end, let's ensure that users requesting the bleeding edge
using the feature.experimental flag *do* get protocol v2.  This way,
we can gain experience with a wider audience for the new protocol
version and be more confident when it is time to enable it by default
for all users in some future Git version.

Implementation note: this isn't with the rest of the
feature.experimental options in repo-settings.c because those are tied
to a repository object, whereas this code path is used for operations
like "git ls-remote" that do not require a repository.

166528d698 Merge branch 'fscache-and-sparse-checkout'
When updating the skip-worktree bits in the index to align with new
values in a sparse-checkout file, Git scans the entire working
directory with lstat() calls. In a sparse-checkout, many of these
lstat() calls are for paths that do not exist.

Enable the fscache feature during this scan.

In a local test of a repo with ~2.2 million paths, updating the index
with `git read-tree -m -u HEAD` with a sparse-checkout file containing
only `/.gitattributes` improved from 2-3 minutes to 15-20 seconds.

More work could be done to stop running lstat() calls when recursing
into directories that are known to not exist.
