Robert Muir commented on LUCENE-5874:
-------------------------------------
Can you comment on the proposal on LUCENE-5858 instead?
I argue there we should remove such ancient codecs from rotation: its annoying
because they dont support the full feature set and just causes a bunch of
wasted time debugging and false failures.
Furthermore this doesn't really bring any value anymore, it doesnt find bugs in
these old codecs, it just brings pain.
Instead we have a better testing directly against old codecs, we have the
mechanism to test these guys directly (various "unit" tests like
BaseXXXFormatTestCase).
We could do this before trying to split out a jar, just as a step.
> Allow choosing latest default codec (not random)

> Project: Lucene - Core
> Issue Type: Test
> Components: modules/test-framework
> Reporter: David Smiley
>
> Within the Lucene/Solr tests, I can see that we want to widely test the
> various Lucene Codecs. And so a test can use a black-list @SuppressCodecs
> when certain codecs are known not to work with certain tests. But there is
> no white-list nor white-list by capabilities (e.g. saying you need term
> vectors that support payloads).
> In external applications that are using the test infrastructure, this is
> annoying. An application generally wants to test with only the codec that
> ships as default with the particular Lucene version they use. Now sure, this
> could be done by using "-Dtests.codec=Lucene46" , or having your
> \@BeforeClass explicitly do Codec.setDefault(Codec.forName("Lucene46")). But
> in both these cases, you have to call out a specific version; you can't
> simply ask for whatever the latest is for the Lucene version you're using
> that's on your classpath. So what I propose is two things: a whitelist
> annotation \@LuceneTestCase.Codecs and a value "CURRENT" (to align with the
> LUCENE_CURRENT naming convention). In this way a test could use the latest
> Codec and not hit a random failure the first time around just because
> Lucene3x or some other old codec was chosen.
