Subject [jira] [Commented] (LUCENE-6431) Make extrasfs reproducible
Date Fri, 17 Apr 2015 11:07:58 GMT


Robert Muir commented on LUCENE-6431:

I'm not worried about "randomness" of this thing at all. That's a false economy.

Reproducibility has to be number one. I'll commit this and anything else is sugar-on-top.

> Today this is really bad, it can easily cause non-reproducible test failures. Its a per-class
thing, but its decisions are based on previous events happening for that class (e.g. directory
> Even using the filename can't work, its setup so early in the process, before test framework
even ensures and similar exist. Even disregarding that, test files use a temp
directory facility and those names are not reproducible (they depend on what already exists,
e.g. from a previous test run).
