[jira] Updated: (LUCENE-2586) move intblock/sep codecs into test
[ https://issues.apache.org/jira/browse/LUCENE-2586?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael McCandless updated LUCENE-2586:
---------------------------------------
Attachment: LUCENE-2586.patch
Attached patch.
It can't be applied because it's a bunch of svn mv's...
But the gist is that intblock/sep in core are now "abstract", moved into test as "MockFixedIntBlock" and "MockSep".

> The intblock and sep codecs in core exist to make it easy for people to try different low-level algos for encoding ints.
> Sep breaks docs, freqs, pos, skip data, payloads into 5 separate files (vs 2 files that standard codec uses).
> Intblock further enables the docs, freqs, pos files to encode fixed-sized blocks of ints at a time.
> So an app can easily "subclass" these codecs, using their own int encoder.
> But these codecs are now concrete, and they use dummy low-level block int encoder (eg encoding 128 ints as separate vints).
> I'd like to change these to be abstract, and move these dummy codecs into test.
> The tests would still test these dummy codecs, by rotating them in randomly for all tests.
> I'd also like to rename IntBlock -> FixedIntBlock, because I'm trying to get a VariableIntBlock working well (for int encoders like Simple9, Simple16, whose block size varies depending on the particular values).
