Category: Extension Modules Group: None Status: Open Resolution: None Priority: 5 Submitted By: Alex Roitman (rshura) >Assigned to: Neal Norwitz (nnorwitz) Summary: bsddb: segfault on db.associate call with Txn and large data Initial Comment: Problem confirmed on Python2.3.5/bsddb4.2.0.5 and Python2.4.2/bsddb4.3.0 on Debian sid and Ubuntu Breezy. It appears, that the associate call, necessary to create a secondary index, segfaults when: 1. There is a large amount of data 2. Environment is transactional. The http://www.gramps-project.org/files/bsddb/testcase.tar.gz contains the example code and two databases, pm.db and pm_ok.db -- both have the same number of keys and each data item is a pickled tuple with two elements. The second index is created over the unpickled data[1]. The pm.db segfaults and the pm_ok.db does not. The second db has much smaller data items in data[0]. If the environment is set up and opened without TXN then pm.db is also fine. Seems like a problem in associate call in a TXN environment, that is only seen with large enough data. Please let me know if I can be of further assistance. This is a show-stopper issue for me, I would go out of my way to help resolving this or finding a work-around. Thanks! Alex P.S. I could not attach the large file, probably due to the size limit on the upload, hence a link to the testcase. ---------------------------------------------------------------------- Comment By: Alex Roitman (rshura) Date: 2006-01-23 21:41 Message: Logged In: YES user_id=498357 Attaching test3.py containing same code without transactions. Works fine with either pm.db or pm_ok.db ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1413192&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
