data and which LC_MONETARY and LC_NUMERIC values it is derived from.
In newlocale(3) and setlocale(3), check for the existing entries and on
miss, create a new entry. This is currently not using a lock for the
list as the worst case is a small memory leak.
Provide LC_GLOBAL_LOCALE in a way that works with all locale functions.
Merge constant data used by the initial global locale and the C locale.
Drop function call layer for _current_locale() and directly return the
locale reference, not a pointer to it. Use protected access for global
variables, so that libc references can avoid the GOT overhead.
called. Use this to implement newlocale and provide duplocale/freelocale
as well. Based on patches by Takehiko Nozaki with simplications and fix
for the init order by myself.
2. unfortunately hppa's MB_LEN_MAX is defined incorrectly 6 instead of 32
so we have to add more setlocale(3) __RENAME func, __setlocale50.
3. move setlocale1.c and setlocale32.c to lib/libc/compat/locale/*
prepareing for next libc major crunk.
4. bump libc minor version.
ok'ed by core and releng.
(thanks for agc@, snj@ and i'm sorry for long time patience).
[libc]
- localeio.[ch] and lc*.[ch] in src/lib/libc/locale was replaced by
new locale-db implementation using citrus_db backend,
see src/lib/libc/citrus/citrus_lc_*.[ch].
- add citrus_bcs_strtou?l.c. don't use strtou?l locale implementation
internally, because they're locale-aware function.
- add some stubs for multi-locale issue, see {current,global}_locale.c.
- remove some obsolete file, setrunelocale.c, ___runetype_mb.c.
- remove __savectype() from ctypeio.[ch].
[tools]
- mklocale(1): add new option ``-t'' that generates new style
LC_{MONETARY,NUMERIC,TIME,MESSAGES} locale-db format.
- chrtbl(1): added ctypeio.[ch] for __savectype().
[locale-db]
- added en_US.US-ASCII locale.
- removed some shareable locale definition file:
en_US.US-ASCII -> en_US.ISO8859-1, en_US.UTF-8
zh_CN.eucCN -> zh_CN.GB18030
and more...see src/share/locale/*/Makefile.
- remove obsoleted locale sr_YU, added new locale sr_ME, sr_RS.
- change locale name ja_JP.ISO2022-JP* -> ja_JP.ISO-2022-JP*
for X11's locale.alias file alignments.
- fix regression test, wrong wcs?width(3), NAN/INF usage.
i tested release-build following arch:
i386, amd64, hpc{mips,arm,sh}, sparc64, vax.
citrus_lc_*.[ch] also can read old-plain-text style locale-db.
so that backward compatibility is keeped, but lc*.[ch] can't read
new citrus_db'ed locale-db and localeio.c never check sanity,
so forward compatibility is broken ;-<
old mklocale(1) doesn't know -t option, so you have to rebuild toolchain.
gencat(1) generated message catalogs. Make sure that it is handled
properly. (I missed this previously.)
Add some additional sanity checks on the locale path as the value may
come from the envrionment.
LC_NUMERIC.
The code used to load LC_TIME was refactored in to a more general routine.
This common routine is now used to load LC_TIME along with the newly added
categories.
Changes discussed with/reviewed by christos.
argunemt and with a string containing many slashes for the second argument.
This bug may cause setlocale() to destroy static datas.
If a setuid program calls this function as 'setlocale(LC_ALL, "");',
this might be vulnerable, although there are few programs having such
vulnerability. This bug probably affects every versions of NetBSD,
including 1.4, 1.5 and 1.6.
XXX: This part of setlocale is unseemly, thus we had better rewrite it in
the future.
have magic number check in locale modules.
rename: lib/libc/locale/setlocale_sb.c -> setlocale1.c
NOTE: this commit does not enable multibyte locale support, yet.
ld.elf_so with citrus locale, it bombs.
XXX this is shortterm workaround. if you are willing to test citrus locale,
use RUNE=yes in libc/locale/Makefile.inc.
for LC_ALL, return success if at least on of categories was loaded
successfully, error if no category was loaded; in the latter case, we don't
need to back off locale changes, since none happened
shot-term TODO:
- enable multibyte locales. this includes loadable locale modules
(#ifdef DLRUNE).
- populate LC_CTYPE definition files.
- other functions such as iconv()
- make libc functions more friendly with multibyte.
- multilingualize other LC_xx
- torture tests
XXX don't forget to "make depend" when you rebuild libc, multibyte.c is
moved from lib/libc/stdlib to lib/libc/locale.
- MB_LEN_MAX is increased to 32.
- To ensure binary compatibility for old executables
under multibyte locale, versioned setlocale is added.
- __mb_len_cur definision is added in setlocale.c
and enable it in stdlib.h .
It is also important for multibyte locale stuffs,
but I just forgot.
loadlocale() fails - since only LC_CTYPE is implemented and all
other categories return error, code never got to actually
load the ctype locales, as first category tried was LC_COLLATE
and it always failed
