Attached is a patch to the airport data storage that I would like committed after review if acceptable. Currently the storage of airports mapped by ID is by locally created objects - about 12 Meg or so created on the stack if I am not mistaken. I've changed this to creating the airports on the heap, and storing pointers to them - see FGAirportList.add(...) in src/Airports/simple.cxx. I believe that this is probably better practice, and it's certainly cured some strange problems I was seeing when accessing the airport data with some gps unit code. Changes resulting from this have cascaded through a few files which access the data - 11 files are modified in all. Melchior and Durk - you might want to test this and shout if there are problems since the metar and traffic code are probably the biggest users of the airport data. I've also added a fuzzy search function that returns the next matching airport code in ASCII sequence in order to support gps units that have autocompletion of partially entered codes. More generally, the simple airport class seems to have grown a lot with the fairly recent addition of the parking, runway preference and schedule time code. It is no longer just an encapsulation of the global airport data file, and has grown to 552 bytes in size when unpopulated (about 1/2 a K!). My personal opinion is that we should look to just store the basic data in apt.dat for all global airports in a simple airport class, plus globally needed data (metar available?), and then have the traffic, AI and ATC subsystems create more advanced airports for themselves as needed in the area of interest. Once a significant number of airports worldwide have ground networks and parking defined, it will be impractical and unnecessary to store them all in memory. That's just a thought for the future though. |
