Category: Python Library Group: None Status: Open Resolution: None Priority: 5 Submitted By: A. Murat EREN (meren) Assigned to: Nobody/Anonymous (nobody) Summary: tarfile can't extract some tar archives.. Initial Comment: Here is a small demo to reproduce the same problem: -----------------8<-----------------8<-----------------8<-----------------8<--- [EMAIL PROTECTED] /home/meren $ wget ftp://ftp.sleepycat.com/releases/db.1.85.tar.gz (...) 100%[============>] 270,953 17.13K/s ETA 00:00 20:21:09 (15.25 KB/s) - `db.1.85.tar.gz' saved [270,953] [EMAIL PROTECTED] /home/meren $ file db.1.85.tar.gz db.1.85.tar.gz: gzip compressed data, from Unix [EMAIL PROTECTED] /home/meren $ python >>> tar = tarfile.open("db.1.85.tar.gz", "r:gz") >>> for tarinfo in tar: ... print tarinfo.name ... db.1.85 db.1.85/btree db.1.85/btree/Makefile.inc db.1.85/btree/bt_close.c db.1.85/btree/bt_conv.c db.1.85/btree/bt_debug.c db.1.85/btree/bt_delete.c db.1.85/btree/btree.h db.1.85/btree/bt_get.c db.1.85/btree/bt_open.c (...) >>> for tarinfo in tar: ... tar.extract(tarinfo) ... >>> Ctrl + D [EMAIL PROTECTED] /home/meren $ ls db* db.1.85 db.1.85.tar.gz [EMAIL PROTECTED] /home/meren $ file db.1.85 db.1.85: empty [EMAIL PROTECTED] /home/meren $ cat db.1.85 [EMAIL PROTECTED] /home/meren $ ----------------->8----------------->8----------------->8----------------->8--- Also this file is extracting with the same result too: ftp://ftp.linux.org.tr/pub/mirrors/gentoo/distfiles/ncompress-4.2.4.tar.gz This thing is very rarely happening, but it is happening. Also, I could extract these archives properly via the native 'tar' binary.. Thanks in advance, Ciao. ---------------------------------------------------------------------- >Comment By: A.

Murat EREN (meren) Date: 2005-10-25 18:36 Message: Logged In: YES user_id=718263 I figured out that this is a very pesky problem. The problem is coming from the tar archives themselves. Simply, the "tarinfo.isdir()" check in the library returns false for the directories and they are extracting like a regular file.. How did they create these fool archives I don't know, and I couldn't reproduce similar buggy archives by myself. It would be nice to know. Because of the problem is not in the python library, it is very difficult to implement an efficent workaround to properly extract this kind of buggy tar archives. I'm going to attach a dirty workaround to show the idea (is anyone reading these reports?).. Ciao.. ---------------------------------------------------------------------- Comment By: A.
