Serhiy Storchaka added the comment: No, on the contrary, it is not such easy to fix, and the patch is incorrect. Sorry that it is not clear either. The size of the header with extra args depends on the size of the file. The file size can be changed in the process of compressing, and compressed size may be larger than uncompressed size, exceeding 32-bit boundary. Rewriting the header with extra args, we can overwrite compressed data.
I was put off the issue for further more careful research. Thanks for the reminder. One solution is always (even for smallest files) to write 64-bit sizes when allowZip64 is true. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9720> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
