* tests/init.cfg (require_timeout_): New function, from grep.
(require_valgrind_): Use it, to kill -9 after 3 seconds, because the
default SIGINT was insufficient.
* tests/init.cfg (require_utf8_locale_): Solaris 10's /usr/bin/tr
silently malfunctions with multibyte input, so attempt to find a
better one, trying /usr/xpg4/bin/tr and "gtr".
Failing that, skip the test. Reported by Collin Funk in
https://lists.gnu.org/r/diffutils-devel/2025-02/msg00004.html
* bootstrap.conf (gnulib_modules): Add c32isspace, c32tolower.
* lib/Makefile.am (noinst_HEADERS): Add mbcel.h.
(libdiffutils_a_SOURCES): Add mbcel.c
* lib/mbcel.c, lib/mbcel.h: New files.
* src/io.c: Include mbcel.h, uchar.h.
(hash): 2nd arg is now hash_value, not merely unsigned char,
since the caller might pass a char32_t now.
(find_and_hash_each_line): Support multi-byte input.
* src/util.c: Include mbcel.h, uchar.h.
(lines_differ): New args S1LEN, S2LEN, needed for mbcel_scan.
Caller changed. Support multi-byte input.
* tests/ignore-case: New file.
* tests/Makefile.am (TESTS): Add it.
* tests/ignore-tab-expansion: Add UTF-8 test.
* tests/init.cfg (require_utf8_locale_): New function.
* tests/side-by-side: Use it. Add a column-counting test.
* tests/init.cfg (stderr_fileno_): Reject valgrind if it reports a
"Serious error" on a trival use of ‘diff’. Without this patch, on
RHEL 8.4 when I compile diffutils with a GCC 11.2.0 that I built
myself, ‘valgrind diff’ spits out messages like WARNING: Serious
error when reading debug info / When reading debug info from diff:
Ignoring non-Dwarf2/3/4 block in .debug_info’ and this causes the
strip-trailing-cr test to fail. I guess valgrind complains
because the valgrind version 3.16.0 that came with RHEL 8.4 cannot
grok the debug entries generated by GCC 11.2.0.
Run "make update-copyright" and then...
* gnulib: Update to latest with copyright year adjusted.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.
Run "make update-copyright" and then...
* gnulib: Update to latest with copyright year adjusted.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.
* tests/init.cfg: New file, for require_valgrind_ definition (from coreutils).
* tests/Makefile.am (PATH): Don't set stderr_fileno_ here, since it is
now initialized in init.cfg.
