Category: Python Library Group: Python 2.3 Status: Open Resolution: None Priority: 5 Submitted By: Robert Kiendl (kxroberto) Assigned to: Nobody/Anonymous (nobody) Summary: ZipFile __del__/close problem with longint/long files Initial Comment: >From a user (py2.3.4 based app) I got only this small trace: I cannot reproduce it easily: --- sync complete: 6 files (0+6), 3488210kB copied. --- 1795.9 Seconds (100.0% CPU Time) Exception exceptions.OverflowError: 'long int too large to convert to int' in <bound method ZipFile.__del__ of <zipfile.ZipFile instance at 0x009D9D50>> ignored ---------------------------------------------------------------------- Comment By: Alan McIntyre (ESRG) (alanmcintyre) Date: 2005-04-14 15:30 Message: Logged In: YES user_id=1115903 Oh, silly me, I didn't notice this: "3488210kB copied," which is of course >2GB (don't know if your number indicates pre- or post-compression though). I'm assuming this means that you're bumping into the limits of the zip file format. Since this sort of thing happens occasionally in some applications I maintain, I will look at making a patch for ZipFile that will at least tell you when you exceed file format limits (either individual file size or total archive file size). ---------------------------------------------------------------------- Comment By: Alan McIntyre (ESRG) (alanmcintyre) Date: 2005-04-14 15:17 Message: Logged In: YES user_id=1115903 How do you reproduce it? I have seen that exception pop up when trying to add a file >2GB to an archive (although in that case it occurred during the call to ZipFile.write rather than __del__). It looks to me like writing the end-of-zip-archive record - during close(), which is called by __del__() - would give this exception if the contents of the archive were > 2GB, but I haven't tried this out to be sure. If that's what's causing the problem, then it would appear to me that it's just a limitation of the ZIP file format, but maybe the ZipFile object could detect this and raise a less cryptic exception. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1182788&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
