#3786 new defect

SDE layers with joined tables and a null filter produce a segfault on retrieving shape by ID

Reported by: ejn Owned by: hobu
Priority: normal Milestone:
Component: Input - Native SDE Support Version: svn-trunk (development)
Severity: normal Keywords: sde, join

Description

For layers from a database join, SDE uses the function getSDESQLConstructInfo to setup the SQL connection. If there is an ID query involved, the layer->filter.string is not checked for a NULL value before being concatenated to the full filter set on the connection (where property of the connection object). This causes a segfault if an attempt is made to retrieve a single record by id from the join layer when the filter is NULL.

Note: to workaround this problem, you can set the layer filter to a dummy value (e.g. "1 = 1"). Affects versions back to at least Mapserver 5.4.2.
