@bug 4123370 4091969 4118731 4182108 4778440
The "at-test" tag was removed from this file, because there's no way to
run this test in an automated test harness. It depends on having various
different locales installed on the machine, and on Windows it depends
on the user going to the "Regional Settings" control panel and changing
the settings before running the test for each bug. We can run this test
manually from time to time to ensure that there has been no regression,
but it's not automated. -- lwerner, 7/6/98
INSTRUCTIONS FOR RUNNING THIS TEST
==================================
This test is designed to check for problems in the JVM code that initializes the
default Java locale (the locale returned by Locale.getDefault()) from the system
locale settings (or from command-line arguments). Since detecting a regression
usually requires setting the environment up in some way prior to running the test,
this is a manual test.
The test simply prints out the internal ID and display name of the default Java locale,
and the name of the default Java character encoding. It passes if these are what
you expect them to be, and fails if they're not.
Bug #4091969:
To test for bug #4091969, run this test on a Korean-localized version of
Windows, with the default locale set to Korean. You should get "ko_KR"
as the default locale.
Bug #4123370:
One part of bug #4123370 duplicates bug #4091969, which is covered by the
instructions above.
To test the unique part of bug #4123370, use the "Regional Settings" control
panel to set the currect locale to each of the different Spanish-language locales.
Run this test once for each Spanish-language locale. You should see the appropriate
locale ID and name for each locale. Both "Spanish - Traditional Sort" and
"Spanish - Modern Sort" should produce "es_ES" and "Spanish (Spain)".
Bug #4118731:
The basic issue here was that we had changed so that calling getDisplayName()
on a locale that didn't include a country code no longer included a country
name (instead of picking a default country name, as before), which is the
right answer. The problem is we weren't always getting back a system default
locale from Solaris that includes a country code, even though we should.
To test this, set the system default locale to a locale that doesn't include
a country code, such as "fr" or "de", using (in the C shell) "setenv LC_ALL fr"
(or whatever the locale ID you want is). Running PrintDefaultLocale should
still produce a locale ID, and a locale display name, that include a country
code (and country name). [Remember to make sure the locale is actually installed
first.]
To test the specific complaint in the bug, use "setenv LC_ALL ja". Also pay
special attention to Solaris locale IDs that don't match the corresponding java
locales, such as "su" (which should turn into "fi_FI"), "cz" (which should turn
into "cs_CZ"), and "en_UK" (which should turn into "en_GB").
Bug #4079167:
Test this bug the same way you test bug #4118731. Set the locale to each of
the specified locale IDs (e.g., "setenv LC_ALL japanese"), and then run
PrintDefaultLocale. You should get the following results:
Solaris ID Java ID Java display name Encoding
========== ======= ==================== ========
japanese ja_JP Japanese (Japan) --
korean ko_KR Korean (South Korea) --
tchinese zh_TW Chinese (Taiwan) --
big5 zh_TW Chinese (Taiwan) Big5
(Where "--" is marked for "encoding," the result isn't important-- it's the
default encoding for that locale, which we don't test. It should be something
plausible. Also note that this test presupposed you actually have locales
with these names installed on your system.)
Bug #4154559, 4778440:
Set the locale to Norwegian (Bokmal) and Norwegian (Nynorsk) using the
Regional Settings control panel on Windows. For each setting, run this program.
You should see no_NO and no_NO_NY, respectively.
Bug #4182108:
Test this bug the same way you test bug #4118731. Set the locale to
each of the specified locale IDs (e.g., "setenv LC_ALL japanese"), and
then run PrintDefaultLocale. You should get the following results:
Solaris ID Java ID Encoding
========== ======= ========
cz cs_CZ --
su fi_FI --
fr.ISO8859-15 fr_FR ISO8859-15
fr.ISO8859-15@euro fr_FR ISO8859-15
Where "--" is marked for "encoding," the result isn't important-- it's
the default encoding for that locale, which we don't test. It should be
something plausible. Also note that this test presupposed you actually
have locales with these names installed on your system.
As of this writing, there is a bug in Solaris or in the 8859-15/euro
patch for 2.6 (Solaris patch 106842-01) which causes nl_langinfo() to
return the wrong value for 8859-15 locales. As a result, the encoding
returned by this test is currency ISO8859-1 for 8859-15 locales.
Bug #4778440, 5005601, 5074060, 5107154:
Run the "deflocale" tool found in "data" directory (deflocale.sh on Unix,
deflocale.exe on Windows), and check the following:
4778440: Check that iw_IL is the default locale if the OS's locale is
Hebrew, and in_ID for Indonesian.
5005601: For Norwegian locales, no_NO is selected for Bokmal, and no_NO_NY
is selected for Nynorsk.
5074060, 5107154: On Windows XP ServicePack 2, check the default locales for the
following Windows locales. Compare with the golden data (deflocale.win):
Bengali - India
Croatian - Bosnia and Herzegovina
Bosnian - Bosnia and Herzegovina
Serbian (Latin) - Bosnia and Herzegovina
Serbian (Cyrillic) - Bosnia and Herzegovina
Welsh - United Kingdom
Maori - New Zealand
