[issue19894] zipfile ignores deflate level settings in zipinfo object

[Jens Diemer]

Jens Diemer added the comment:

IMHO it should be possible to set compression level not only for DEFLATE.
And it should be similar with the tarfile API.

Seems that http://bugs.python.org/issue21417 will cover this.

[issue19894] zipfile ignores deflate level settings in zipinfo object

[Richard Milne]

New submission from Richard Milne:

Reading the pkzip APPNOTE and the documentation for the zipfile module, I was 
under the impression that I could set the DEFLATE compression level, on a 
per-file basis, for each file added to an archive, by setting the appropriate 
bits in zipinfo.flag_bits.

You can't. Hence the attached patch, which updates the docs, tests and module 
source to enables this ability and makes the user aware of it.
