Hi, As I mentioned earlier I'd like to get patch 1446489 (support for zip64 extensions in the zipfile module) in python 2.5. The patch should be perfectly safe, it comes with unittests and a documentation update. I'm also using this version of zipfile in (closed-source) projects to handle huge zipfiles.
There are two backward incompatbile changes, both minor. First of all ZipInfo will lose the file_offset attribute because calculating it when opening a zipfile is very expensive (it basically requires a full scan of the zipfile). This should be harmless, I couldn't come up with a usecase other then reimplementing the read method outside of zipfile. The second incompatibility is that zipfile will try to raise an error when the zipfile gets to large, instead of reducing the zipfile to garbage as the current revision of zipfile does. The major changes in the patch are: support for ZIP64 extensions which make it possible to handle zipfiles that are larger than 2 GByte in size and a significant speed-up of zipfile opening when dealing with zipfiles that contain a large amount of files. These are in one patch because large zipfiles support isn't very useful when opening the zipfile takes more than 30 seconds.
