2001-09-25 <NotZed@Ximian.com> * camel-operation.c (camel_operation_unref): Fix for !threads enabled not ccompiling. (camel_operation_ref): Assert refcount > 0. (struct _CamelOperation): Removed the lock. On further investigation, I dont think this will always work, the registration operations assume that a lookup in the operation_active table will return a ref, that will remain valid until we ref it, which needn't be the case. So now i'm using a single global lock, since we'd need to do that for unref anyway, and every operation is fast & memory-bound. Changed all the code to handle this. (camel_operation_progress_count): Since the code is identical, just call progress() for now. (camel_operation_register): No longer refcount, use unref to check/clear the active table. (camel_operation_unregister): Same here. (camel_operation_unref): Check if operation is in active table, if so, warn, remove. svn path=/trunk/; revision=13125
