libidn-1.42 released [stable]

[Simon Josefsson]

This is to announce libidn-1.42, a stable release.

GNU Libidn is a fully documented implementation of the Stringprep,
Punycode and IDNA2003 specifications.  Libidn's purpose is to encode and
decode internationalized domain name strings.  There are native C, C#
and Java libraries.  Be aware that IDNA2003 and libidn are primarily for
historic or compatibility use, and libidn2 is the successor with
IDNA2008 and Unicode TR46 implementation and also provides a
compatibility layer for GNU libidn.

There have been 65 commits by 3 people in the 81 weeks since 1.41.

See the NEWS below for a brief summary.

For a summary of changes and contributors, see:
  https://git.sv.gnu.org/gitweb/?p=libidn.git;a=shortlog;h=v1.42
or run this command from a git-cloned libidn directory:
  git shortlog v1.41..v1.42

Here are the compressed sources and a GPG detached signature:

Here are the SHA1 and SHA256 checksums:

  32234b883584c190e73a8b479903ad5f4f5bd39b  libidn-1.42.tar.gz
  1sGZ3NgG5P4nk2DLSwg0mg05Vg7VSP/RzK3ajN7LRyM=  libidn-1.42.tar.gz

Verify the base64 SHA256 checksum with cksum -a sha256 --check
from coreutils-9.2 or OpenBSD's cksum since 2007.

Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify libidn-1.42.tar.gz.sig

The signature should match the fingerprint of the following key:

  pub   ed25519 2019-03-20 [SC]
        B1D2 BD13 75BE CB78 4CF4  F8C4 D73C F638 C53C 06BE
  uid   Simon Josefsson <simon@josefsson.org>

If that command fails because you don't have the required public key,
or that public key has expired, try the following commands to retrieve
or refresh it, and then rerun the 'gpg --verify' command.

  gpg --locate-external-key simon@josefsson.org

  gpg --recv-keys 51722B08FE4745A2

  wget -q -O- 
'https://savannah.gnu.org/project/release-gpgkeys.php?group=libidn&download=1' 
| gpg --import -

As a last resort to find the key, you can try the official GNU
keyring:

  wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg
  gpg --keyring gnu-keyring.gpg --verify libidn-1.42.tar.gz.sig

NEWS

* Noteworthy changes in release 1.42 (2024-01-13) [stable]

** Bump required gettext version to 0.19.8 for musl-libc.

** Compiler warning improvements.
As before, compiler warnings are enabled by default.  You may disable
them using ./configure --disable-gcc-warnings or turn them into fatal
errors using ./configure --enable-gcc-warnings=error to add -Werror
and sensible -Wno-error='s.  Based on gnulib's manywarnings, see
<https://www.gnu.org/software/gnulib//manual/html_node/manywarnings.html>.

** Fix type confusion on LLP64/Windows platforms.
While libidn has worked using cygwin libc, it has never worked on
ucrt/msvcrt libc.  Report and tiny patch by Francesco Pretto in
<https://lists.gnu.org/archive/html/help-libidn/2022-02/msg00000.html>.

** tests: Added script tests/standalone.sh suitable for integrators.
The main purpose is to test a system-installed libidn, suitable for
distributor checking (a'la Debian's autopkgtest/debci).  It may also
be used to test a newly built libidn outside the usual 'make check'
infrastructure.  To check that your system libidn is working, invoke
the script with `srcdir` as an environment variable indicating where
it can be find the source code for libidn's tests/ directory (it will
use the directory name where the script is by default):

tests/standalone.sh

To check that a newly built static libidn behaves, invoke:

env STANDALONE_CFLAGS="-Ilib lib/.libs/libidn.a" tests/standalone.sh

To check that a newly built shared libidn behaves, invoke:

env srcdir=tests STANDALONE_CFLAGS="-Ilib -Wl,-rpath lib/.libs 
lib/.libs/libidn.so" tests/standalone.sh

If the libidn under testing is too old and has known bugs, that should
cause tests to fail, which is intentional.

** Updated translations.

** Update gnulib files and build fixes.
