Martin Panter added the comment: I’m not sure that is perfectly correct. It really does default to -1, and that is passed to the underlying zlib library (-1 = Z_DEFAULT_COMPRESSION). It is the zlib library that decides that this means 6, but in theory I guess it could be configured or modified in the future with a different default. Perhaps we should clarify the text in the documentation (including the doc string) to say this instead?
At the very least, the documentation should continue to say that -1 is acceptable, and what it means. ---------- nosy: +martin.panter stage: -> patch review versions: +Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26244> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
