Subject [compress] in-place updates of archive contents
Date Fri, 25 May 2012 14:21:32 GMT

I'm looking for a archive format and library that allows to update a archive entry w/o copying
the whole file as necessary with zip file format.

From what I've seen, tar may be possible but the compress API does not state this use case
explicitly? Is this supported?
I also saw the ChangeSetPerformer API but the test cases mostly use cpio and zip, Thus, I'm
not sure.

Thanks for any pointers on how to create an updatable archive w/o copying a 1gb++ archive
