sah_RU locale file for glibc

Dear maintainers,

I created glibc locale data for Yakut (Sakha) language (sah_RU) and want to submit it.

Please find attached the locale definition for sah_RU to be
considered for inclusion in glibc.

Git repo: https://github.com/qfoxxy/glibc-sah_RU

sah_RU locale file for glibc

Thank you for providing this new locale file. Here is my review:

>escape_char  /
>comment_char  %

This is correct but I think there is no need to have two spaces after "escape_char" and "comment_char".

Also, as stated in bug 1123, here should be the legal formula starting with:
"% This file is part of the GNU C Library and contains locale data."

See: https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=a4cea54

>% Yakut (Sakha) locale for Russian Federation
>% Source: Valery Timiriliyev
>% Email: timiriliyev@gmail.com

Probably it does not matter much but there is no need to put "none" in parentheses.

I don't understand what is this "Repertoiremap" comment.  I suggest to remove it.

We have agreed to remove this line because this is misleading.  See:

I haven't tested this but I've compared the source code with the Yakut alphabet as described in Wikipedia.  Looks good.  Please ignore the Unicode issues of my browser. :-)

THE MAJOR ISSUE HERE: The abday and day arrays must always start with Sunday.  If you want to display Monday first it will be specified elsewhere.

CLDR says that Wednesday abbreviation should be "сэ" while yours is "ср".  We tend to trust CLDR more so please consider changing to "сэ" or report an issue to CLDR.

Friday: CLDR says "Бээтиҥсэ" while your version is "бээтинсэ".  I believe that it's CLDR's bug to start with the uppercase "Б" because all other letters are lowercase (please report an issue) but there is still the difference "ҥ" vs. "н".  Please switch to CLDR version or report an issue to CLDR.

CLDR says "Клн" and "Мсу" here while your version is "кул" and "муус".  I believe it's CLDR bug to start with uppercase but I'd rather believe CLDR regarding other letters.  Regarding uppercase vs. lowercase: for the languages which don't need different grammatical cases for standalone vs. formatting month names CLDR suggests that standalone month names can start with uppercase while formatting can start with lowercase.

September: CLDR says "Блҕ" while your version is "бал".  Same comment as above.

I suggest adding commas after the month names at the end of each line to avoid confusion.  One may think that "ыам ыйа бэс ыйа" is a single month name with a line broken inside.

I am confused here: CLDR says "ыам ыйа" if the month name is standalone (same as your version so probably it is correct) but "Ыам ыйын" when it is in a formatting context.  Which version is correct, modulo upper/lowercase?

Same comment everywhere above.  Additionally, for August CLDR consequently says "атырдьых" while your version says "атырдьах".  Please fix.

Typo: s/Abreviated/Abbreviated, and please don't exceed 80 chars per line.

Please don't use non-ASCII characters in the data.  We have agreed to use the ASCII characters directly so it is correct to write "%a %Y" but "с" should be "<U0441>" instead.

It seems that it's not a problem to skip "first_workday" here but please add to avoid confusion:

Correct but we have agreed that "+" and "1" should be included in yesexpr
and "-" and "0" should be included in noexpr.
See: https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=f982160

Please include "yesstr" and "nostr" here.  They should contain "yes" and "no" in Yakut language, respectively.  Their capitalization should be based on the regular grammar rules, not assuming that they are in the beginning of the sentence.

It would be nice if you could provide country_isbn, otherwise this section LGTM.

Now when you fix these bugs please provide a patch instead of a file.  The patch should add this file and add the language to localedata/SUPPORTED.  Though, I'm not sure ATM if the new line in localedata/SUPPORTED should be "sah_RU/UTF-8" or "sah_RU.UTF-8/UTF-8".  Please see some examples of patches which add a new language:

Note that the file locale/iso-639.def already contains a line for Yakut language but please verify if it is correct.  It says "Yakut" while you provide "Yakut (Sakha)".  I believe your version is correct.

ru_RU contains:

copy "i18n"

include  "translit_combining";""

I think all characters must be there because the “i18n” file is
generated by Python scripts from Unicode data and contains all
characters in Unicode.

So unless Yakut needs any changes to the character classes in that
“i18n” file, using that should be fine (for example Turkish needs
differences in “toupper” and “tolower” because of the ı <-> I and
i <-> İ pairs of lowercase/uppercase letters).

And if Yakut doesn’t need special translit rules, using
copy "ru_RU" should be fine.

The relevant part at the link Rafal gave is:

    WEEKSTARTDATE specifies the base of the abday and day lists

    first_weekday specifies the offset of the first day-of-week in the
    abday and day lists

    For compatibility reasons, all locales should set WEEKSTARTDATE on
    19971130 (Sunday) and base the abday and day lists appropriately,
    and set first_weekday 1 or 2 depending to whether their week
    actually starts on Sunday or Monday.

So you should set "first_weekday 2" if you want to display Monday in
the first column of a calendar but start the abday arrays with Sunday

I think "sah_RU/UTF-8" is better.

A patch to add sah_RU language

The original file converted to a patch.

Also, since after writing the original patch we have agreed to use the raw ASCII characters instead of <U00.. sequences wherever this is 100% nondestructive I have converted most of them to ASCII.  No other errors fixed so the comments above are still valid.  Could you please respond, Valery?
Comment 6 Rafal Luzynski 2018-06-20 23:33:33 UTC
Now since the support of standalone (nominative, alternative) and full date format (genitive, non-alternative) month names has been added to glibc and Yakut language seems to use this feature (e.g., "May" - "ыам ыйа"; but "1st of May" - "1 Ыам ыйын") I find this patch incomplete.  It needs an update or at least an explanation from a native speaker.  For example, I am not sure if it is correct that CLDR lists the "Months - Wide - Formatting" uppercased except December while "Months - Wide - Standalone" are lowercased.

Comment 9 Rafal Luzynski 2018-07-12 10:16:13 UTC
I must say that I'm impressed with the high quality of this patch. However, here are some nitpicks:

+% ab_alt_mon - The alternative abbreviations for the months
+% - тохс, олун, кул, муус, ыам, бэс, от, атыр, бал, алт, сэт, ахс
+ab_alt_mon  "<U0442><U043E><U0445><U0441>";"<U043E><U043B><U0443><U043D>";/
+            "<U043A><U0443><U043B>";"<U043C><U0443><U0443><U0441>";/
+            "<U044B><U0430><U043C>";"<U0431><U044D><U0441>";/
+            "<U043E><U0442>";"<U0430><U0442><U044B><U0440>";/
+            "<U0431><U0430><U043B>";"<U0430><U043B><U0442>";/
+            "<U0441><U044D><U0442>";"<U0430><U0445><U0441>"
+% abmon and ab_alt_mon are actually identical.

There is no need to provide ab_alt_mon if it is identical to abmon. This is not destructive but so far we have never added ab_alt_mon when it was identical to abmon (and alt_mon when it was identical to mon). The point is that these arrays are identical in majority of languages and we don't want to disturb them.

> +mon         "<U0442><U043E><U0445><U0441><U0443><U043D><U043D><U044C><U0443>";/

What about using a plain space (" ") instead of "<U0020>"?

Could you please use ASCII characters wherever they are ASCII, that is "^" instead of "<U005E>" and so on? So it should be:

+yesexpr "^[+1yY<U0434><U0414><U044D><U042D>]"
+noexpr "^[-0nN<U043D><U041D><U0441><U0421>]"

+copy "ru_RU"

Good but it could also contain the Sakha translations for "Mr.", "Mrs.", and so on. However, ru_RU has the same problem. On the other hand, I don't think this information is actually used by any real application.

Same here, ASCII could be used.
Comment 10 Rafal Luzynski 2018-07-12 19:46:12 UTC
More updates:

Here is "<U0025><U0025>" which decodes to "%%" - double percent sign, I'm pretty sure this is a typo.

2. I think we need an entry in NEWS, same as for Lower Sorbian: https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=a1e0c5f The explanation is: normally we don't mention explicitly newly added languages in NEWS (they are added automatically but this time we mention the languages which distinguish between mon and alt_mon. I think it is fair not to omit the languages which are newly added and also distinguish between mon and alt_mon. This is true for both Lower Sorbian and Yakut.
Comment 11 Rafal Luzynski 2018-07-12 20:50:37 UTC
> +% FIXME: Not sure if all letters from Yakut alphabet are there.
> +copy "ru_RU"

Yes, it contains all letters from Yakut alphabet.  ru_RU contains “copy "i18n"” and i18n contains all letters from all alphabets (to a reasonable extent): https://sourceware.org/git/?p=glibc.git;a=blob;f=localedata/locales/i18n_ctype;hb=HEAD

I'm removing this comment.

This fails with these error messages:

I think that whole this section must be reworked.  Also:

> +% Ҕ after Г

The default sort order is:

> "г" < " ⷢ" < "Г" < "ѓ" < "Ѓ" < "ґ" < "Ґ" < "ғ" < "Ғ" < "ӻ" < "Ӻ" < "ҕ" < "Ҕ" < "ӷ" < "Ӷ" < "д" < ...

I think that this reorder will produce:

> "г" < "ҕ" < " ⷢ" < "Г" < "Ҕ" < "ѓ" < "Ѓ" < "ґ" < "Ґ" < "ғ" < "Ғ" < "ӻ" < "Ӻ" < "ӷ" < "Ӷ" < "д" < ...

I think that instead you would like:

> "г" < " ⷢ" < "Г" < "ѓ" < "Ѓ" < "ґ" < "Ґ" < "ғ" < "Ғ" < "ӻ" < "Ӻ" < "ӷ" < "Ӷ" < "ҕ" < "Ҕ" < "д" < ...

which means you must put "Cyrillic GHE with middle hook" after "Cyrillic GHE with descender" rather than just after "Cyrillic GHE".  Yes, this inconvenient.

The same comment about other reorders.

I didn't expected reaction like this. Thanks.

> What about using a plain space (" ") instead of "<U0020>"?
Sure. I'll replace the Unicode codes for ASCII characters with the characters themselves.

> Here is "<U0025><U0025>" which decodes to "%%" - double percent sign, I'm pretty sure this is a typo.
Because that field is identical to that of ru_RU, I'll just copy it from there.

> I think we need an entry in NEWS
I have to provide it?

> I think that whole this section must be reworked.
Yes, I need some time to sort this out.

In Yakut alphabet only one letter placed in non-standard position: "Һ". In all other Cyrillic alphabet is usually comes after "Х", but in our alphabet it's after "С" (because actually Һ is allophone of С in Yakut language). I think only that letter need to be included in LC_COLLATE, isn't it?

(Things are getting too complicated for my level of English, sorry if you can't understand what I've written :)

I saw several locales using "%%" and many more using exactly the same format but with a single "%". I guess it is a typo copied several times.

I've already adjusted sah_RU to contain the same as ru_RU.

You or me or whoever. I've added this already in the attached patch.

I've checked the Yakut alphabet in Wikipedia and I've added this change and also some more:

* "Ҕ" after "Ӷ" and before "Д" (otherwise would be between "Ӻ" and "Ӷ"),
* "Дь" after "Ԃ" and before "Ҙ" (otherwise would be between "Дӹ" and "Дҍ"),
* "Ҥ" after "Ԋ" (otherwise would be between "Ԣ" and "Њ"),
* immediately followed by "Нь" (which otherwise would be between "Нӹ" and "Нҍ") and by "О",
* "Ө" is by default after "Ӧ" and before "Ӫ", I think it is fine and I leave it unchanged,
* also "Ү" is by default after "Ӯ" and before "Ұ", also I think that no change is needed.

I still can't understand what is the "<PCL>" symbol in your collating rules. If you can't explain then I will remove it and use the symbols which I can understand.

I can't see any problem with your English but my English is also not perfect. :-)

New locale: Yakut (Sakha) (version 4)

Hopefully this is the final version.  Changes since the v3:

* Symbols like <YAK-GHE> converted to lowercase (<yak-ghe> and so on).
* "<PCL>" no longer used as this is probably outdated/old/unsupported etc.
* Missing symbols <d-soft-sign-digraph> and <n-soft-sign-digraph> added.
* Added a comment explaining how the Yakut alphabet looks + Wikipedia link.

Looks good.

It also compiles and installs without error.

The GNU C Library

The GNU C Library version 2.28 is now available.

The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.

The GNU C Library is primarily designed to be a portable
and high performance C library.  It follows all relevant
standards including ISO C11 and POSIX.1-2008.  It is also
internationalized and has one of the most complete
internationalization interfaces known.

The GNU C Library webpage is at http://www.gnu.org/software/libc/

Packages for the 2.28 release may be downloaded from:

The mirror list is at http://www.gnu.org/order/ftp.html

NEWS for version 2.28

Major new features:

* The localization data for ISO 14651 is updated to match the 2016
  Edition 4 release of the standard, this matches data provided by
  Unicode 9.0.0.  This update introduces significant improvements to the
  collation of Unicode characters.  This release deviates slightly from
  the standard in that the collation element ordering for lowercase and
  uppercase LATIN script characters is adjusted to ensure that regular
  expressions with ranges like [a-z] and [A-Z] don't interleave e.g. A
  is not matched by [a-z].  With the update many locales have been
  updated to take advantage of the new collation information.  The new
  collation information has increased the size of the compiled locale
  archive or binary locales.

* The GNU C Library can now be compiled with support for Intel CET, AKA
  Intel Control-flow Enforcement Technology.  When the library is built
  with --enable-cet, the resulting glibc is protected with indirect
  branch tracking (IBT) and shadow stack (SHSTK).  CET-enabled glibc is
  compatible with all existing executables and shared libraries.  This
  feature is currently supported on i386, x86_64 and x32 with GCC 8 and
  binutils 2.29 or later.  Note that CET-enabled glibc requires CPUs
  capable of multi-byte NOPs, like x86-64 processors as well as Intel
  Pentium Pro or newer.  NOTE: --enable-cet has been tested for i686,
  x86_64 and x32 on non-CET processors.  --enable-cet has been tested
  for x86_64 and x32 on CET SDVs, but Intel CET support hasn't been
  validated for i686.

* The GNU C Library now has correct support for ABSOLUTE symbols
  (SHN_ABS-relative symbols).  Previously such ABSOLUTE symbols were
  relocated incorrectly or in some cases discarded.  The GNU linker can
  make use of the newer semantics, but it must communicate it to the
  dynamic loader by setting the ELF file's identification (EI_ABIVERSION
  field) to indicate such support is required.

* Unicode 11.0.0 Support: Character encoding, character type info, and
  transliteration tables are all updated to Unicode 11.0.0, using
  generator scripts contributed by Mike FABIAN (Red Hat).

* <math.h> functions that round their results to a narrower type are added
  from TS 18661-1:2014 and TS 18661-3:2015:

  - fadd, faddl, daddl and corresponding fMaddfN, fMaddfNx, fMxaddfN and
    fMxaddfNx functions.

  - fsub, fsubl, dsubl and corresponding fMsubfN, fMsubfNx, fMxsubfN and
    fMxsubfNx functions.

  - fmul, fmull, dmull and corresponding fMmulfN, fMmulfNx, fMxmulfN and
    fMxmulfNx functions.

  - fdiv, fdivl, ddivl and corresponding fMdivfN, fMdivfNx, fMxdivfN and
    fMxdivfNx functions.

* Two grammatical forms of month names are now supported for the following
  languages: Armenian, Asturian, Catalan, Czech, Kashubian, Occitan, Ossetian,
  Scottish Gaelic, Upper Sorbian, and Walloon.  The following languages now
  support two grammatical forms in abbreviated month names: Catalan, Greek,
  and Kashubian.

* Newly added locales: Lower Sorbian (dsb_DE) and Yakut (sah_RU) also
  include the support for two grammatical forms of month names.

* Building and running on GNU/Hurd systems now works without out-of-tree

* The renameat2 function has been added, a variant of the renameat function
  which has a flags argument.  If the flags are zero, the renameat2 function
  acts like renameat.  If the flag is not zero and there is no kernel
  support for renameat2, the function will fail with an errno value of
  EINVAL.  This is different from the existing gnulib function renameatu,
  which performs a plain rename operation in case of a RENAME_NOREPLACE
  flags and a non-existing destination (and therefore has a race condition
  that can clobber the destination inadvertently).

* The statx function has been added, a variant of the fstatat64
  function with an additional flags argument.  If there is no direct
  kernel support for statx, glibc provides basic stat support based on
  the fstatat64 function.

* IDN domain names in getaddrinfo and getnameinfo now use the system libidn2
  library if installed.  libidn2 version 2.0.5 or later is recommended.  If
  libidn2 is not available, internationalized domain names are not encoded
  or decoded even if the AI_IDN or NI_IDN flags are passed to getaddrinfo or
  getnameinfo.  (getaddrinfo calls with non-ASCII names and AI_IDN will fail
  with an encoding error.)  Flags which used to change the IDN encoding and
  deprecated.  They no longer have any effect.

* Parsing of dynamic string tokens in DT_RPATH, DT_RUNPATH, DT_NEEDED,
  DT_AUXILIARY, and DT_FILTER has been expanded to support the full
  range of ELF gABI expressions including such constructs as
  '$ORIGIN$ORIGIN' (if valid).  For SUID/GUID applications the rules
  have been further restricted, and where in the past a dynamic string
  token sequence may have been interpreted as a literal string it will
  now cause a load failure.  These load failures were always considered
  unspecified behaviour from the perspective of the dynamic loader, and
  for safety are now load errors e.g. /foo/${ORIGIN}.so in DT_NEEDED
  results in a load failure now.

* Support for ISO C threads (ISO/IEC 9899:2011) has been added.  The
  implementation includes all the standard functions provided by

  - thrd_current, thrd_equal, thrd_sleep, thrd_yield, thrd_create,
    thrd_detach, thrd_exit, and thrd_join for thread management.

  - mtx_init, mtx_lock, mtx_timedlock, mtx_trylock, mtx_unlock, and
    mtx_destroy for mutual exclusion.

  - call_once for function call synchronization.

  - cnd_broadcast, cnd_destroy, cnd_init, cnd_signal, cnd_timedwait, and
    cnd_wait for conditional variables.

  - tss_create, tss_delete, tss_get, and tss_set for thread-local storage.

  Application developers must link against libpthread to use ISO C threads.

Deprecated and removed features, and other changes affecting compatibility:

* The nonstandard header files <libio.h> and <_G_config.h> are no longer
  installed.  Software that was using either header should be updated to
  use standard <stdio.h> interfaces instead.

* The stdio functions 'getc' and 'putc' are no longer defined as macros.
  This was never required by the C standard, and the macros just expanded
  to call alternative names for the same functions.  If you hoped getc and
  putc would provide performance improvements over fgetc and fputc, instead
  investigate using (f)getc_unlocked and (f)putc_unlocked, and, if
  necessary, flockfile and funlockfile.

* All stdio functions now treat end-of-file as a sticky condition.  If you
  read from a file until EOF, and then the file is enlarged by another
  process, you must call clearerr or another function with the same effect
  (e.g. fseek, rewind) before you can read the additional data.  This
  corrects a longstanding C99 conformance bug.  It is most likely to affect
  programs that use stdio to read interactive input from a terminal.
  (Bug #1190.)

* The macros 'major', 'minor', and 'makedev' are now only available from
  the header <sys/sysmacros.h>; not from <sys/types.h> or various other
  headers that happen to include <sys/types.h>.  These macros are rarely
  used, not part of POSIX nor XSI, and their names frequently collide with
  user code; see https://sourceware.org/bugzilla/show_bug.cgi?id=19239 for
  further explanation.

  <sys/sysmacros.h> is a GNU extension.  Portable programs that require
  these macros should first include <sys/types.h>, and then include
  <sys/sysmacros.h> if __GNU_LIBRARY__ is defined.

* The tilegx*-*-linux-gnu configurations are no longer supported.

* The obsolete function ustat is no longer available to newly linked
  binaries; the headers <ustat.h> and <sys/ustat.h> have been removed.  This
  function has been deprecated in favor of fstatfs and statfs.

* The obsolete function nfsservctl is no longer available to newly linked
  binaries.  This function was specific to systems using the Linux kernel
  and could not usefully be used with the GNU C Library on systems with
  version 3.1 or later of the Linux kernel.

* The obsolete function name llseek is no longer available to newly linked
  binaries.  This function was specific to systems using the Linux kernel
  and was not declared in a header.  Programs should use the lseek64 name
  for this function instead.

  getaddrinfo and getnameinfo functions have been deprecated.  The behavior
  previously selected by them is now always enabled.

  the getaddrinfo and getnameinfo functions have been deprecated.  The STD3
  restriction (rejecting '_' in host names, among other things) has been
  removed, for increased compatibility with non-IDN name resolution.

* The fcntl function now have a Long File Support variant named fcntl64.  It
  is added to fix some Linux Open File Description (OFD) locks usage on non
  LFS mode.  As for others *64 functions, fcntl64 semantics are analogous with
  fcntl and LFS support is handled transparently.  Also for Linux, the OFD
  locks act as a cancellation entrypoint.

* The obsolete functions encrypt, encrypt_r, setkey, setkey_r, cbc_crypt,
  ecb_crypt, and des_setparity are no longer available to newly linked
  binaries, and the headers <rpc/des_crypt.h> and <rpc/rpc_des.h> are no
  longer installed.  These functions encrypted and decrypted data with the
  DES block cipher, which is no longer considered secure.  Software that
  still uses these functions should switch to a modern cryptography library,
  such as libgcrypt.

* Reflecting the removal of the encrypt and setkey functions above, the
  macro _XOPEN_CRYPT is no longer defined.  As a consequence, the crypt
  function is no longer declared unless _DEFAULT_SOURCE or _GNU_SOURCE is

* The obsolete function fcrypt is no longer available to newly linked
  binaries.  It was just another name for the standard function crypt,
  and it has not appeared in any header file in many years.

* We have tentative plans to hand off maintenance of the passphrase-hashing
  library, libcrypt, to a separate development project that will, we hope,
  keep up better with new passphrase-hashing algorithms.  We will continue
  to declare 'crypt' in <unistd.h>, and programs that use 'crypt' or
  'crypt_r' should not need to change at all; however, distributions will
  need to install <crypt.h> and libcrypt from a separate project.

  In this release, if the configure option --disable-crypt is used, glibc
  will not install <crypt.h> or libcrypt, making room for the separate
  project's versions of these files.  The plan is to make this the default
  behavior in a future release.

Changes to build and runtime requirements:

  GNU make 4.0 or later is now required to build glibc.

Security related changes:

  CVE-2016-6261, CVE-2016-6263, CVE-2017-14062: Various vulnerabilities have
  been fixed by removing the glibc-internal IDNA implementation and using
  the system-provided libidn2 library instead.  Originally reported by Hanno
  Böck and Christian Weisgerber.

  CVE-2017-18269: An SSE2-based memmove implementation for the i386
  architecture could corrupt memory.  Reported by Max Horn.

  CVE-2018-11236: Very long pathname arguments to realpath function could
  result in an integer overflow and buffer overflow.  Reported by Alexey

  CVE-2018-11237: The mempcpy implementation for the Intel Xeon Phi
  architecture could write beyond the target buffer, resulting in a buffer
  overflow.  Reported by Andreas Schwab.
