MP aircraft are loaded by a separate OSG thread (introduced after FG2.4.0). The OSG thread also calls the "modelLoaded" callback. However, we mustn't allow the OSG thread to call FGNasalModelData::modelLoaded directly: FGNasalModelData isn't thread-safe. There are obvious issues (_callCount++;), tricky issues like calling the Nasal _parser_ or creating hashes and modifying the global Nasal namespace. It doesn't use locks to protect against another thread executing a Nasal context or running garbage collection. It also executes Nasal code itself (the model's "load" hook), which we also cannot allow in a separate thread... This patch returns all Nasal parts of MP-aircraft loading (parsing, module creation, execution) to the main thread, while keeping the multi-threaded OSG part (loading of MP-aircraft model files itself). The same issue exists with scenery models (see other commit). To summarize with 2 words: It s*cks... ;-) |
