commit 2ab8b74567dc0a9a3c98696e6444881997dd6c49
Author: Carlos O'Donell <carlos@redhat.com>

localedef: Update LC_MONETARY handling (Bug 28845)
ISO C17, POSIX Issue 7, and ISO 30112 all allow the char*
types to be empty strings i.e. "", integer or char values to
be -1 or CHAR_MAX respectively, with the exception of
decimal_point which must be non-empty in ISO C. Note that
the defaults for mon_grouping vary, but are functionaly
equivalent e.g. "\177" (no further grouping reuqired) vs.
"" (no grouping defined for all groups).
We include a broad comment talking about harmonizing ISO C,
POSIX, ISO 30112, and the default C/POSIX locale for glibc.
We reorder all setting based on locale/categories.def order.
We soften all missing definitions from errors to warnings when
defaults exist.
Given that ISO C, POSIX and ISO 30112 allow the empty string
we change LC_MONETARY handling of mon_decimal_point to allow
the empty string. If mon_decimal_point is not defined at all
then we pick the existing legacy glibc default value of
<U002E> i.e. ".".
We also set the default for mon_thousands_sep_wc at the
same time as mon_thousands_sep, but this is not a change in
behaviour, it is always either a matching value or L'\0',
but if in the future we change the default to a non-empty
string we would need to update both at the same time.
Tested on x86_64 and i686 without regressions.
Tested with install-locale-archive target.
Tested with install-locale-files target.

+ /* Generally speaking there are 3 standards the define the default,
+ warning, and error behaviour of LC_MONETARY. They are ISO/IEC TR 30112,
+ ISO/IEC 9899:2018 (ISO C17), and POSIX.1-2017. Within 30112 we have the
+ definition of a standard i18n FDCC-set, which for LC_MONETARY has the
+ following default values:
+ int_curr_symbol ""
+ currency_symbol ""
+ mon_decimal_point "<U002C>" i.e. ","

+ p_sep_by_space -1
+ n_cs_precedes -1
+ n_sep_by_space -1
+ p_sign_posn -1
+ n_sign_posn -1
+ Under 30112 a keyword that is not provided implies an empty string ""
+ for string values or a -1 for integer values, and indicates the value
+ is unspecified with no default implied. No errors are considered.
+ The exception is mon_grouping which is a string with a terminating
+ CHAR_MAX.
+ For POSIX Issue 7 we have:
+ https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap07.html
+ and again values not provided default to "" or -1, and indicate the value
+ is not available to the locale. The exception is mon_grouping which is
+ a string with a terminating CHAR_MAX. For the POSIX locale the values of
+ LC_MONETARY should be:
+ int_curr_symbol ""
+ currency_symbol ""
+ mon_decimal_point ""
+ mon_thousands_sep ""
+ mon_grouping "\177" i.e. CHAR_MAX
+ positive_sign ""
+ negative_sign ""
+ int_frac_digits -1
+ frac_digits -1

+ p_sep_by_space -1

+ p_sign_posn -1
+ n_sign_posn -1
+ int_p_cs_precedes -1

+ int_n_cs_precedes -1
+ int_n_sep_by_space -1
+ int_p_sign_posn -1
+ int_n_sign_posn -1
+ Like with 30112, POSIX also considers no error if the keywords are
+ missing, only that if the cateory as a whole is missing the referencing
+ of the category results in unspecified behaviour.
+ For ISO C17 there is no default value provided, but the localeconv
+ specification in 7.11.2.1 admits that members of char * type may point
+ to "" to indicate a value is not available or is of length zero.
+ The exception is decimal_point (not mon_decimal_point) which must be a
+ defined non-empty string. The values of char, which are generally
+ mapped to integer values in 30112 and POSIX, must be non-negative
+ numbers that map to CHAR_MAX when a value is not available in the
+ locale.
+ In ISO C17 for the "C" locale all values are empty strings "", or
+ CHAR_MAX, with the exception of decimal_point which is "." (defined
+ in LC_NUMERIC). ISO C17 makes no exception for mon_grouping like
+ 30112 and POSIX, but a value of "" is functionally equivalent to
+ "\177" since neither defines a grouping (though the latter terminates
+ the grouping).
+
+ Lastly, we must consider the legacy C/POSIX locale that implemented
+ as a builtin in glibc and wether a default value mapping to the
+ C/POSIX locale may benefit the user from a compatibility perspective.
+
+ Thus given 30112, POSIX, ISO C, and the builtin C/POSIX locale we
+ need to pick appropriate defaults below. */

commit 1c7a34567d21fbd3b706c77cd794956b43daefe7
Author: Carlos O'Donell <carlos@redhat.com>
Date: Thu Feb 3 16:01:52 2022 -0500
localedata: Do not generate output if warnings were present.
With LC_MONETARY parsing fixed we can now generate locales
without forcing output with '-c'.
Removing '-c' from localedef invocation is the equivalent of
using -Werror for localedef. The glibc locale sources should
always be clean and free from warnings.
We remove '-c' from both test locale generation and the targets
used for installing locales e.g. install-locale-archive, and
install-locale-files.
Tested on x86_64 and i686 without regressions.
Tested with install-locale-archive target.
Tested with install-locale-files target.
