Dawid Weiss commented on COMPRESS-320:
--------------------------------------
I created a pull request on github, here:
https://github.com/apache/commons-compress/pull/8
It contains four commits (can be flattened if needed, but I'd preserve the
history as it allows cleaner separation of previous behavior vs. the one after
a patch). The change is fully backward compatible. If one calls
{{getNextEntry}} in succession, the call will now be much faster since block
decompression for solid archives is deferred until really needed. This,
together with COMPRESS-333 would also resolve COMPRESS-291 since one can now
now both selectively scan the archive and decompress arbitrary items.

> Key: COMPRESS-320
> URL: https://issues.apache.org/jira/browse/COMPRESS-320
> Project: Commons Compress
> Issue Type: Improvement
> Components: Archivers
> Reporter: Bill Chen
> Priority: Minor
>
> I guess these must be one of the most wanted features and it should be very
> simple to implement (as I have done one in 126 lines).
> Most (if not all) of the infrastructure is already there, including an index
> of all files. And, with some careful coding, the capability to read any of
> them in any order concurrently was not difficult to add.
> My code uses loads of lambda and reflection stuff, but I am happy to
> contribute a clean Java 5/6 implementation.
