root/main/trunk/greenstone2/runtime-src/src/colservr/collectset.h @ 21455

Revision 21455, 2.2 KB (checked in by ak19, 10 years ago)

Major bug fix after Dr Bainbridge debugged the server code which was causing the server to crash upon Enter Library: the line where it failed was simply where a local-scope text_t object was being naturally destructed. The real error was a memory corruption which the use of the new heapchk function helped to locate: collectset's inherited method configure() ought to have been specified as virtual, since it was declared virtual in the superclass configurable. A couple of destructors (in collectset and oaiservr's oaiconfig) have been made virtual as well since the superclass configurable has virtual methods which requires all related destructors to be virtual.
