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: SQL/Core Group: SQL CVS Head Status: Open Resolution: None Priority: 5 Private: No Submitted By: Stefan de Konink (skinkie) Assigned to: Niels Nes (nielsnes) Summary: select * where bla = "whatever" crashes Initial Comment: Some of our 'friendly' webservice users tried MonetDB in a somewhat disturbing way, resulting in a segmentation fault of the server. The query in the subject will reproduce it from mclient as well. ---------------------------------------------------------------------- >Comment By: Stefan de Konink (skinkie) Date: 2009-07-31 07:08 Message: selection->h is not available with broken queries, must be explicitly checked before use. Removes void cast of where because the variable is in use. The origin of the problem was a user entering a malformed query on my webinterface that segfaulted monet. The patch implements a null check to prevent n->* to be used. ---------------------------------------------------------------------- Comment By: Stefan Manegold (stmane) Date: 2009-07-31 05:59 Message: Would it be possible to provide a context diff to ensure correct automatic application (or prevent incorrect application automatic application) even in case the original code base has changed in the meantime? Would it be possible to provide the context diff in unified format to improve human readability? (admittedly personal taste) Would it be possible to explain/document the details of the patch, and hence enlighten us what the origin of the actual problem was, and how it has been solved? Thank you very much in advance! ---------------------------------------------------------------------- Comment By: Stefan de Konink (skinkie) Date: 2009-07-23 16:35 Message: The attached file basically prevents the crash, but I wonder if we can solve it higher in the tree. Output now is: sql>select * where bla = "whatever"; !SELECT: identifier 'bla' unknown 0 tuples So that looks good :) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=482468&aid=2825974&group_id=56967 ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
