            Bug ID: 16905
           Summary: New collation for hanzi
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: localedata
          Assignee: unassigned at sourceware dot org

hanzi collation by stroke

Please find attached the collation for hanzi(chinese characters) to be
considered for inclusion in glibc.

The order is based on the stroke data from http://www.cns11643.gov.tw/

There is already iso14651_t1_pinyin in glibc, so I just named this file as
iso14651_t1_stroke which may not be a proper name.

--- Comment #1 from 趙惟倫 <bluebat at member dot fsf.org> ---
I have realized, according to bug 14095, that this file may have nothing to do
with iso14651.

The license of data from http://www.cns11643.gov.tw/ looks BSD-like, so I have
forked a project https://github.com/bluebat/cfs11643

Should this collation be named as cfs11643_stroke ?

            Bug ID: 16965
           Summary: tst-strtod-round fails on 32-bit sparc
           Product: glibc

tst-strtod-round fails on 32-bit sparc with the following errors:

-0x0.0000000000000001p-16382 (FE_UPWARD)

Digging into the code, the issue is that __mpn_rshift is called with cnt = 0,
while stdlib/rshift.c explicitly says that cnts should satisfy 0 < CNT <
BITS_PER_MP_LIMB. In this case, the code end up doing a logical shift right of
the same size than the register (32 bit there), which is undefined in the C
standard.

While the problem appears on sparc for this specific value, I believe that it
is possible to find values which do not work on architectures which only use
the lower part of the register to get the shift amount. This includes for
example mips or aarch64.

Patch will follow soon on the mailing list.

--- Comment #18 from Mike FABIAN <maiku.fabian at gmail dot com> ---
(In reply to Pravin S from comment #14)

I checked the scripts Pravin used and the resulting UTF-8 file.

I found only one minor problem:

In some cases, both UnicodeData.txt and EastAsianWidth.txt have information
about width. For example, EastAsianWidth.txt has:

    302A..302D;W     # Mn     [4] IDEOGRAPHIC LEVEL TONE MARK..IDEOGRAPHIC
ENTERING TONE MARK

which gives us width 2 for these 4 characters (because of “W”) but
UnicodeData.txt has:

    302A;IDEOGRAPHIC LEVEL TONE MARK;Mn;218;NSM;;;;;N;;;;;
    302B;IDEOGRAPHIC RISING TONE MARK;Mn;228;NSM;;;;;N;;;;;
    302C;IDEOGRAPHIC DEPARTING TONE MARK;Mn;232;NSM;;;;;N;;;;;
    302D;IDEOGRAPHIC ENTERING TONE MARK;Mn;222;NSM;;;;;N;;;;;

which would give width 0 (because of “NSM”).

I changed Pravin’s script a bit to prefer the information from
EastAsianWidth.txt in case of conflicts.

Pravin has already merged my change into his git repository.

The range check already rejects names that are 16 characters or longer.  If you
are getting EINVAL that means you are trying to set the name of a thread in a
different process.
