On the current AArch64 buildbot the default 20s timeout is not
enough to run this test, it seems
make test t=locale/tst-localedef-path-norm
takes about 25s, so i increased the timeout to 30s.
During testing of localedef running in a minimal container
there were several error cases which were hard to diagnose
since they appeared as strerror (errno) values printed by the
higher level functions. This change adds three new verbose
messages for potential failure paths. The new messages give
the user the opportunity to use -v and display additional
information about why localedef might be failing. I found
these messages useful myself while writing a localedef
container test for --no-hard-links.
Since the changes cleanup the code that handle codeset
normalization we add tst-localedef-path-norm which contains
many sub-tests to verify the correct expected normalization of
codeset strings both when installing to default paths (the
only time normalization is enabled) and installing to absolute
paths. During the refactoring I created at least one
buffer-overflow which valgrind caught, but these tests did not
catch because the exec in the container had a very clean heap
with zero-initialized memory. However, between valgrind and
the tests the results are clean.
The new tst-localedef-path-norm passes without regression on
x86_64.

The locale/tst-locale-locpath test unsets LANG, then runs a test with
test_wrapper_env and expects LANG to remain unset for that test. This
does not work for cross-testing with cross-test-ssh.sh when sshd (on
the system specified as an argument to cross-test-ssh.sh) is
configured to have a default LANG setting.
The general design used in cross testing, after commit
8540f6d2a7 ("Don't require test wrappers
to preserve environment variables, use more consistent environment.",
6 June 2014), is that environment settings required by tests should be
passed explicitly to $(test-wrapper-env). This patch changes
tst-locale-locpath.sh to pass an explicit LANG= rather than expecting
"unset LANG" to be in effect for the program run under
test_wrapper_env. Note that this does slightly change the environment
in which the test is run natively (empty LANG instead of unset LANG)
but that difference does not appear relevant to what it is trying to
test.
Tested for Arm that this fixes the failure seen for that test in
cross-testing.
I've updated copyright dates in glibc for 2020. This is the patch for
the changes not generated by scripts/update-copyrights and subsequent
build / regeneration of generated files. As well as the usual annual
updates, mainly dates in --version output (minus libc.texinfo which
previously had to be handled manually but is now successfully updated
by update-copyrights), there is a fix to
sysdeps/unix/sysv/linux/powerpc/bits/termios-c_lflag.h where a typo in
the copyright notice meant it failed to be updated automatically.
Please remember to include 2020 in the dates for any new files added
in future (which means updating any existing uncommitted patches you
have that add new files to use the new copyright dates in them).

The patch is non-exhaustive. Apart from architecture-specific code

-Wimplicit-fallthrough=3 (the default level with -Wextra; my
inclination is to adjust those comments to match rather than
downgrading to -Wimplicit-fallthrough=1 to allow any comment), or one
place where I thought the implicit fallthrough was not correct and so

Downstream distributions need consistent sets of hardlinks in
order for rpm to operate effectively. This means that even if
locales are built with a high level of parallelism that the
resulting files need to have consistent hardlink counts. The only
way to achieve this is with a post-install hardlink pass using a
program like 'hardlink' (shipped in Fedora).
If the downstream distro wants to post-process the hardlinks then
the time spent in localedef looking up sibling directories and
processing hardlinks is wasted effort.
To optimize the build and install pass we add a --no-hard-links
option to localedef to avoid doing the hardlink optimziation for
size.
Tested on x86_64 with 'make localedata/install-locale-files'
before and after. Without the patch we have files with 100+
hardlink counts. After the patch and running with --no-hard-links
all link counts are 1. This patch also alters the convenience
target 'make localedata/install-locale-files' to use the new
option.

Continuing fixes for -Os build issues shown with build-many-glibcs.py,
this patch adds uses of DIAG_* to disable -Wmaybe-uninitialized in two
more places where code inlined from strcoll / wcscoll is wrongly
diagnosed as possibly using uninitialized structure fields. (All
these warnings in different places for these functions are I think
essentially the same bug.)
Tested with build-many-glibcs.py for alpha-linux-gnu and
mips-linux-gnu that this fixes the -Os build failures for those
configurations with GCC 7.
* locale/weightwc.h (findidx): Ignore -Wmaybe-uninitialized for

The findidx functions used in implementing strcoll / wcscoll already
use DIAG_IGNORE_Os_NEEDS_COMMENT for spurious -Wmaybe-uninitialized
warnings that appear with -Os. In building with GCC 7 for x86_64 with
-Os, I find there are additional such warnings, for the same structure
elements, which are spurious for the same reasons given in the
existing comments (and this was also reported for MIPS with GCC 5 in
bug 21313). This patch adds corresponding uses of DIAG_* in the
places that get the additional warnings.
Tested for x86_64 with -Os that this eliminates those warnings and so
allows the build to progress further.

Some languages (Slavic, Baltic, etc.) require a genitive case of the
month name when formatting a full date (with the day number) while
they require a nominative case when referring to the month standalone.
This requirement cannot be fulfilled without providing two forms for
each month name. From now it is specified that nl_langinfo(MON_1)
series (up to MON_12) and strftime("%B") generate the month names in
the grammatical form used when the month is a part of a complete date.
If the grammatical form used when the month is named by itself is needed,
the new values nl_langinfo(ALTMON_1) (up to ALTMON_12) and
strftime("%OB") are supported. This new feature is optional so the
languages which do not need it or do not yet provide the updated

There were several problems with checking the array size in the past,
for example BZ#356, caused by incorrectly assuming that every locale
token represents one element. In fact, if a token represented
a subarray, for example an array of month names or characters category
and it appeared at the end of the array the compiler assumed that
the array ends just after the first element of the subarray.
A workaround used in the past was to skip some categories while testing,
for example LC_CTYPE. Now when we are about to add alternative month
names to LC_TIME (BZ#10871) this will fail again.

Locales using SHIFT_JIS and SHIFT_JISX0213 character maps are not ASCII
compatible. In order to build locales using these character maps, and
have localedef exit with a status of 0, we add new option to localedef
to disable or enable specific warnings. The options are --no-warnings
and --warnings, to disable and enable specific warnings respectively.
The options take a comma-separated list of warning names. The warning
names are taken directly from the generated warning. When a warning
that can be disabled is issued it will print something like this: foo is
not defined [--no-warnings=foo]
For the initial implementation we add two controllable warnings; first
'ascii' which is used by the localedata installation makefile target to
install SHIFT_JIS and SHIFT_JISX0213-using locales without error; second
'intcurrsym' which allows a program to use a non-standard international
currency symbol without triggering a warning. The 'intcurrsym' is
useful in the future if country codes are added that are not in our
current ISO 4217 list, and the user wants to avoid the warning. Having
at least two warnings to control gives an example for how the changes
can be extended to more warnings if required in the future.
These changes allow ja_JP.SHIFT_JIS and ja_JP.SHIFT_JISX0213 to be
compiled without warnings using --no-warnings=ascii. The
localedata/Makefile $(INSTALL-SUPPORTED-LOCALES) target is adjusted to
automatically add `--no-warnings=ascii` for such charmaps, and likewise
localedata/gen-locale.sh is adjusted with similar logic.

In "Is it OK to write ASCII strings directly into locale source files?"
https://sourceware.org/ml/libc-alpha/2017-07/msg00807.html there is
universal consensus that we do not have to keep writing <Uxxxx> symbolic
characters in locale files.
Ulrich Drepper's historical comment was that symbolic characters were
used for the eventuality of converting the source files to any encoding
system. Fast forward to today and UTF-8 is the standard. So the
requirement of <Uxxxx> is hard to justify.
Zack Weinberg's excellent scripts are coming along we can use these to
find instances of human errors in the scripts:
https://sourceware.org/ml/libc-alpha/2017-07/msg00860.htmlhttps://sourceware.org/ml/libc-alpha/2017-08/msg00136.html
It still won't be easy to distinguish from i for í, but that's still the
case for <Uxxxx> characters which humans can't read either.
Since we all agreed that we should be able to use non-symbolic (<Uxxxx>)
characters in locale files, the following change removes the verbose
warning that is raised if you use non-symbolic characters in the locale
file.

Therefore to support non-builtin locales with similar "" int_curr_symbol
we adjust the LC_MONETARY parser to allow the normal 4-character
int_curr_symbol *and* the empty "" no symbol. Anything else remains
invalid.
Tested by building all the locales. Tested also with a custom C.UTF-8

The error and warning handling in localedef, locale, and iconv
is a bit of a mess.
We use ugly constructs like this:
WITH_CUR_LOCALE (error (1, errno, gettext ("\
cannot read character map directory `%s'"), directory));
to issue errors, and read error_message_count directly from the
error API to detect errors. The problem with that is that the
code also uses error to print warnings, and informative messages.
All of this leads to problems where just having warnings will
produce an exit status as-if errors had been seen.
To fix this situation I have adopted the following high-level
changes:
* All errors are counted distinctly.
* All warnings are counted distinctly.
* All informative messages are not counted.
* Increasing verbosity cannot generate *more* errors, and
it previously did for errors conditional on verbose,
this is now fixed.
* Increasing verbosity *can* generate *more* warnings.
* Making the output quiet cannot generate *fewer* errors,
and it previously did for errors conditional on be_quiet,
this is now fixed.
* Each of error, warning, and informative message has it's
own function to call defined in record-status.h, and they
are: record_error, record_warning, and record_verbose.
* The record_error function always records an error, but
conditional on be_quiet may not print it.
* The record_warning function always records a warning,
but conditional on be_quiet may not print it.
* The record_verbose function only prints the verbose
message if verbose is true and be_quiet is false.
This has allowed the following fix:
* Previously any warnings were being treated as errors
because they incremented error_message_count, but now
we properly return an exit status of 1 if there are
warnings but output was generated.
All of this allows localedef to correctly decide if errors,
or warnings were present, and produce the correct exit code.
The locale and iconv programs now also use record-status.h
and we have removed the WITH_CUR_LOCALE hack, and instead
have internal push_locale/pop_locale functions centralized
in the record routines.
