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

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.

transport: extract common fetch_pack() call
In the switch statement, the difference between the `protocol_v2` and
`protocol_v{1,0}` arms is a preparatory call to die_if_server_options() in
the latter. The fetch_pack() call is identical in both arms. However,
since this fetch_pack() call has so many parameters, it is not
immediately obvious that the call is identical in both cases.
Extract the common fetch_pack() call out of the switch statement so that
code duplication is reduced and the logic is more clear for future
readers. While we're at it, rewrite the switch statement as an if-else
tower for increased clarity.

git-sparse-checkout.txt: add missing '
Where we explain the 'reapply' command, we don't properly wrap it in
single quote marks like we do with the other commands: We omit the
closing mark ("'reapply") and this ends up being rendered literally as
"'reapply". Add the missing "'".

The first list item follows immediately on the paragraph where we

huge paragraph. (With AsciiDoc, everything is fine after that, but with
Asciidoctor, we get some minor follow-on errors.) Add an empty line --
with a list continuation ("+") -- to make the first list item render ok.

t4210: detect REG_ILLSEQ dynamically and skip affected tests
7187c7bbb8 (t4210: skip i18n tests that don't work on FreeBSD, 2019-11-27)
adds a REG_ILLSEQ prerequisite, and to do that copies the common branch in
test-lib and expands it to include it in a special case for FreeBSD.
Instead; test for it using a previously added extension to test-tool and
use that, together with a function that identifies when regcomp/regexec
will be called with broken patterns to avoid any test that would otherwise
rely on undefined behaviour.
The description of the first test which wasn't accurate has been corrected,
and the test rearranged for clarity, including a helper function that avoids
overly long lines.
Only the affected engines will have their tests suppressed, also including
"fixed" if the PCRE optimization that uses LIBPCRE2 since b65abcafc7
(grep: use PCRE v2 for optimized fixed-string search, 2019-07-01) is not
available.

t/helper: teach test-regex to report pattern errors (like REG_ILLSEQ)
7187c7bbb8 (t4210: skip i18n tests that don't work on FreeBSD, 2019-11-27)
adds a REG_ILLSEQ prerequisite to avoid failures from the tests added in 4e2443b181 (log tests: test regex backends in "--encode=<enc>" tests,
2019-06-28), but hardcodes it to be only enabled in FreeBSD.
Instead of hardcoding the affected platform, teach the test-regex helper,
how to validate a pattern and report back, so it can be used to detect the
same issue in other affected systems (like DragonFlyBSD or macOS).
While at it, refactor the tool so it can report back the source of the
errors it founds, and can be invoked also in a --silent mode, when needed,
for backward compatibility. A missing flag has been added and the code
reformatted, as well as updates to the way the parameters are handled, for
consistency.
To minimize changes, it is assumed the regcomp error is of the right type
since we control the only caller, and is also assumed to affect both basic
and extended syntax (only basic is tested, but both behave the same in all
three affected platforms since they use the same function).
