Schmidt <schmidt@tango.cs.wustl.edu> + + * ace: Replaced all uses of "delete mb" with mb->release (); + + * ace/Stream_Modules.cpp: Replaced the use of explicit bit + twiddling with the ACE_BIT* macros. + + * ace/Message_Block.cpp: Make sure that we use the + allocator_strategy_ to create the memory for the reference count + since this may need to go into shared memory if that's the + memory pool where the Message_Block allocations are coming from. + + * ace/OS.h: Added two new macros, ACE_ALLOCATOR_RETURN and + ACE_ALLOCATOR, which are similar to ACE_NEW_RETURN and ACE_NEW, + except that these + + * ace/Message_Block.cpp (release): Make sure to "delete this" + outside the scope of the locking_strategy_. + + * ace/Service_Object.cpp: Added a destructor to ACE_Service_Type. + Thanks to Per.Andersson@hfera.ericsson.se (Per Andersson) for + suggesting this. + + * ace/Service_Object.i: Be smarter about how we reassign the name_ + pointer, i.e., delete the old one and make a copy. Thanks to + Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting + this. + + * ace/Module.cpp (open): Rearranged the assignments to + reader_q->mod_ and writer_q->mod_ so that we don't try to + initialize through NULL pointers. Thanks to + Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting + this. + + * ace/Service_Record.cpp (ACE_Service_Record): Initialized name_ + to NULL so that the following change works correctly now. + Thanks to Per.Andersson@hfera.ericsson.se (Per Andersson) for + reporting this. + + * ace/Service_Record.i (name): Make sure to delete [] (char *) + this->name_ before allocating a new one. Thanks to + Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting + this. + + * ace/Message_Block: Reworked the reference counting implemention + so that reference counts are shared correctly amongst their + various owners. This requires making a deep copy the "header" + portion, but a shallow copy of the "data." + + * ace/Message_Block.cpp (ACE_Message_Block): Updated all three + ACE_Message_Block constructors so that they all call the init() + method. This centralizes all the initialization logic in one + place. + Thu Jan 2 00:42:21 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + * ace/Message_Block.cpp (ACE_Message_Block): Make sure to set the + cont_ field to 0 after "releasing" it so that we don't + mistakenly think it's still around later on. This problem arose + in the ACE_Message_Queue::close() method, which was trying to + count the number of bytes being freed. + + * ace/Message_Queue.cpp (close): Fixed a subtle bug where we + weren't actually deleting messages from the + ACE_Message_Queue::close() routine. This should work now... + + * ace/Message_Queue.cpp (close): Replaced the use of "delete mb" + with "mb->release()" since the Message_Blocks are now reference + counted. + + * ace/Message_Block: Enhanced the reference counting scheme so + that you can increment and decrement the count by an arbitrary + amount. This is particular useful when you know you'll be + sending the same Message_Block to N consumers. + + * ace/Singleton: The dump() must be used same as instance() + (without supplying an object) so it must be declarated *static*, + i.e., + + static void dump (void); + + Thanks to Sandro Doro <alex@aureus.sublink.org> for reporting + this. + * examples/ASX/Event_Server: Completely rewrote and retested the ACE Event Server example. The new code is *much* easier to understand, has many more comments, is more robust, and compiles |
