Hi team,

please review German translation update for Git 2.48. There are about 40 new or updated messages.
Update window closes on 5 January, so I'll send a PR to the l10n coordinator by 4 January at the latest.

Thanks
Ralf

bulk-checkin: fix segfault with unsafe SHA1 backend
9218c0b 
In 1b9e9be (csum-file.c: use unsafe SHA-1 implementation when
available, 2024-09-26) we have converted our `struct hashfile` to use
the unsafe SHA1 backend, which results in a significant speedup. One
needs to be careful with how to use that structure now though because
callers need to consistently use either the safe or unsafe variants of
SHA1, as otherwise one can easily trigger corruption.

As it turns out, we have one inconsistent usage in our tree because we
directly initialize `struct hashfile_checkpoint::ctx` with the safe
variant of SHA1, but end up writing to that context with the unsafe
ones. This went unnoticed so far because our CI systems do not exercise
different hash functions for these two backends, and consequently safe
and unsafe variants are equivalent. But when using SHA1DC as safe and
OpenSSL as unsafe backend this leads to a crash an t1050:

builtin/fast-import: fix segfault with unsafe SHA1 backend
106140a 
Same as with the preceding commit, git-fast-import(1) is using the safe
variant to initialize a hashfile checkpoint. This leads to a segfault
when passing the checkpoint into the hashfile subsystem because it would

The segfault is only exposed in case the unsafe and safe backends are

unix-socket: fix memory leak when chdir(3p) fails
c5fe29f 
When trying to create a Unix socket in a path that exceeds the maximum
socket name length we try to first change the directory into the parent
folder before creating the socket to reduce the length of the name. When
this fails we error out of `unix_sockaddr_init()` with an error code,
which indicates to the caller that the context has not been initialized.
Consequently, they don't release that context.

This leads to a memory leak: when we have already populated the context
with the original directory that we need to chdir(3p) back into, but
then the chdir(3p) into the socket's parent directory fails, then we
won't release the original directory's path. The leak is exposed by
t0301, but only when running tests in a directory hierarchy whose path
is long enough to make the socket name length exceed the maximum socket
name length:

    Direct leak of 129 byte(s) in 1 object(s) allocated from:

    SUMMARY: LeakSanitizer: 5 byte(s) leaked in 1 allocation(s).

As the `branch` variable may contain a string constant obtained from
parsing command line arguments we cannot free the leaking variable
directly. Instead, introduce a new `branch_to_free` variable that only
ever gets assigned the allocated string and free that one to plug the
leak.

It is unclear why the leak isn't flagged when running the test via our
Makefile.

config.mak.uname: only set NO_REGEX on cygwin for v1.7
064eed3 
Commit 92f63d2 ("Cygwin 1.7 needs compat/regex", 2013-07-19) set
the NO_REGEX build variable because the platform regex library failed
some of the tests (t4018 and t4034), which passed just fine with the
compat library.

After some time (maybe a year or two), the platform library had been
updated (with an import from FreeBSD, I believe) and now passed the full
test-suite. This would be about the time of the v1.7 -> v2.0 transition
in 2015. I had a patch ready to send, but just didn't get around to
submitting it to the list. At some point in the interim, the official
cygwin git package used the autoconf build system, which sets the
NO_REGEX variable to use the platform regex library functions. The new
meson build system does likewise.

The cygwin platform regex library, in addition to now passing the tests
which formerly failed, now passes an 'test_expect_failure' test in the
t7815-grep-binary test file. In particular, test #12 'git grep .fi a'
which determines that the regex pattern '.' matches a NUL character.
The commit f96e567 ("grep: use REG_STARTEND for all matching if
available", 2010-05-22) added the test in question, but it does not
give any indication as to why the test was framed as an expected fail,
rather than a 'positive' test that the 'git grep' command fails to
match a NUL. Note that the previous test #11 was also originally
marked in that commit as a 'test_expect_failure', but was flipped to
an 'success' test in commit 7e36de5 ("t/t7008-grep-binary.sh: un-TODO
a test that needs REG_STARTEND", 2010-08-17).

In order to produce the same NO_REGEX configuration from autoconf, meson
and make, modify config.mak.uname to only set NO_REGEX for cygwin v1.7.
In addition, skip test t7815.12 on cygwin, by adding the !CYGWIN pre-
requisite to the test header, which (among other things) removes an
'...; please update test(s)' comment.
