I'm filing this case for Jan "Honza" Hnatek, Jan "Jenda" Lana, and
Ning "Harry" Fu as a self-review and automatic approval case since
there is no new architectural change with this case and at the same time,
this is yet another locale EOF with similar cases in the past.
If you disagree, let me know and I'll promote this case to a fast track.

4. Technical Description
OVERVIEW
We have 113 so-called short form locale names being provided and
supported at Solaris such as "ar", "de", "fr_CH", and so on that are
constant sources of customer confusions (and thus also service requests or
customer inquiries) and, for us, a maintenance headache.
The reason for the customer confusions is that such locale names are not
fully qualified with other possible attributes in the names thereby have
inherent ambiguities in identifying intended territory, codeset, or both.
As a background information, all modern POSIX-like operating systems
including Solaris, AIX, HP-UX, and various Linux distributions provide
and support locale names with the following convention [1]:
language_territory.codes...@modifier]
where the "language" is a 2-letter language code from ISO 639 [2],
the "territory" is a 2-letter uppercase territory code from ISO 3166 [3],
the "codeset" is one of the widely accepted codeset names in the industry,
and the optional "@modifier" is an arbitrary string denoting an extra
attribute that is specific to the locale such as a collation order.
The reason why this is a maintenance headache for us is due to that for
almost all of them sans "ar" and "ja" locales, we already have corresponding
fully qualified long form locale names being supported in Solaris and, in fact,
the short form locales are implemented and supported simply by having numerous
symbolic links to the long form locales. (There are a few hundreds of symbolic
links in this aspect.)
There are also six long form locale names that are no longer correct due to
the changes in ISO 639 and ISO 3166 and requiring new locale names going
forward [2, 3, 4, 5, 6]:
Locales with deprecated codes Locales with new codes
----------------------------- ----------------------
no_NO.ISO8859-1 at bokmal nb_NO.ISO8859-1
no_NO.ISO8859-1 at nynorsk nn_NO.ISO8859-1
sh_BA.UTF-8 bs_BA.UTF-8
sh_BA.ISO8859-2 at bosnia bs_BA.ISO8859-2
sr_CS.UTF-8 sr_ME.UTF-8, sr_RS.UTF-8
sr_YU.ISO8859-5 sr_ME.ISO8859-5, sr_RS.ISO8859-5
And a long form locale name of th_TH.ISO8859-11 that is merely a symbolic link
which also should be mapped to th_TH.TIS620.
With this project, the project team would like to EOF the 120 locales
described at above and also the actual list shown at the "PROPOSED
INTERFACE CHANGES AND RELEASE BINDING" subsection at below.
DETAILS ON THE EOF
Once approved by ARC and Solaris P-Team, we will do the EOF announcement at
an S10 UR Release Notes with [7] and do the EOF execution at OpenSolaris and
Solaris Next.
The EOF announcement text will describe our intention that the locale names
will be obsoleted in future releases of Solaris and OpenSolaris and provide
a mapping table which will list the locale names that should be used instead.
Since we don't have "ar_EG.ISO8859-6" locale at this point, for a proper
migration of the "ar" locale, we will create "ar_EG.ISO8859-6" locale as soon
as possible as recorded in [8].
While we think that the "ja" can be mapped to "ja_JP.eucJP" locale we have,
since they are slightly different such that the "ja" locale conforms to
the traditional specification from earlier Solaris releases and
the "ja_JP.eucJP" locale conforms to "UI-OSF Japanese Environment
Implementation Agreement Version 1.1", if we get customer escalation,
we may need to revert the EOF and re-deliver the "ja" locale.
(A side note: As a separate project, to aid customer transitions, we will also
try to provide a transparent locale mapping and alias support mechanism at
libc so that even after the EOF execution is done, customers with old locale
names will still be supported as much as possible.)
