[jira] [Created] (LUCENE-4020) Tests may not be repeatable across
different platforms/ JVMs due to different locale/ timezone being picked.
Dawid Weiss created LUCENE-4020:
-----------------------------------
Summary: Tests may not be repeatable across different platforms/ JVMs due to different locale/ timezone being picked.
Key: LUCENE-4020
URL: https://issues.apache.org/jira/browse/LUCENE-4020
Project: Lucene - Java
Issue Type: Bug
Reporter: Dawid Weiss
Assignee: Dawid Weiss
Priority: Minor
Fix For: 4.0
This is because the source array can be/ is different for each system/ JVM. So this pick is not repeatable for example:
{code}
/**
* Return a random Locale from the available locales on the system.
*/
public static Locale randomLocale(Random random) {
Locale locales[] = Locale.getAvailableLocales();
return locales[random.nextInt(locales.length)];
}
{code}
I don't think there is much we can do to make it repeatable (other than maybe enforcing locale using system property).

-------------------------------------
don't we need to also take care to still consume the same number of random bits
when these params are specified?

Hoss Man commented on LUCENE-4020:
----------------------------------
straw man suggestion:
change the impl of randomLocale(Random) to ensure that it only returns Locale objects that can be round tripped...
{code}
public static Locale randomLocale(final Random outerRandom) {
// consume a fixed amount of randomness from outerRandom
final Random random = new Random(outerRandom.nextLong());
Locale locales[] = Locale.getAvailableLocales();
Locale result = null;
for (int i = 0; i < 100; i++) {
Locale candidate = locales[random.nextInt(locales.length)];
try {
Locale roundTrip = localeForName(candidate.toString());
if (candidate.equals(roundTrip)) {
result = candidate;
break;
}
} catch (Exception e) {
// :NOOP: ... go around again
}
}
if (null == result) {
throw new YourJvmIsFuckedException("Gave up trying to pick a random Locale")
}
return result;
}

but your jvm isnt fucked, and we should test the new java 7 locales.
Its just this idea of roundtripping without using anything but java7 BCP47 apis is fucked.

Robert Muir commented on LUCENE-4020:
-------------------------------------
Patch is on 4021 for round trip parsing (in 6 and 7). It should also work across 6 and 7,
e.g. in on java6 we emit th_TH_TH, on java7 th_TH_TH_#u-nu-thai, but both are constructed as th_TH_TH.
This is ok because of the backwards mechanism (Special Cases) listed in http://docs.oracle.com/javase/7/docs/api/java/util/Locale.htm

-------------------------------------
I think the "reproduce with" line should explicitly state the timezone and locale picked for the test. Granted, certain combinations will be invalid on other JVMs/ systems, but at least it's explicit what should be used?

Hoss Man commented on LUCENE-4020:
----------------------------------
so the exception name isn't great ... but the point is there should be a decent number of Locales that work, and we should be able to try N times to find one, nad if we really don't then give up because we can't run a reproducible test.
(or hell: don't give up .. try 100 times and if we still don't get one that round trips just use whatever we did get and let the user deal with the fact that they can't pass that locale back in to reproduce if it fails)

different platforms/ JVMs due to different locale/ timezone being picked.

-------------------------------------
It'll fail on 1.7 and those darn script variant locales should they be picked for the test... The first time it does, I'll think what to do about it.
