Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: PF/runtime Group: MonetDB4 4.22 Status: Open Resolution: None Priority: 5 Private: No Submitted By: Wouter Alink (vzzzbx) Assigned to: Nobody/Anonymous (nobody) Summary: XQ: updates under stress Initial Comment: updates can still corrupt an xml-document. in the attached 'bug.tgz' there is a tiny script that repeatedly does two things: - check the validity of an xml-document under stress - do a small update on an xml-document if this script is run it will only output 0's, meaning that the document is still valid. if this script is run in 3 threads at the same time, it will (within short time) return non-'0' values, which indicate the document has been corrupted. how to use the script: - start bin/Mserver --dbinit="module(pathfinder);" - insert start.xml as an updatable document named 'test.xml', for example with a free-percentage of 10 - start do.sh in 3 different shells - wait this was tested with the monetdb-install.sh script (on feb 12). monetdb says: # MonetDB Server v4.22.0 # based on GDK v1.22.0 # Copyright (c) 1993-2008, CWI.
