Subject [jira] [Commented] (COMPRESS-320) File listing and random access of 7Z files
Date Sun, 28 Feb 2016 19:51:18 GMT


Dawid Weiss commented on COMPRESS-320:

Oh, I didn't take it the wrong way, no worries at all. I just think it's not "resolvable"
and I tried to explain why. It's much like the 7z format not being suitable for streaming
decompression (because the metadata is kept at the end of the stream, which kind of defeats
the whole idea) -- this is a "won't fix" resolution for me.

> 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.
