It implements a thread-safe system for registering, managing and executing callbacks that run at the start and end of TorchDynamo compilations. Key features include: - Registration and deregistration of compilation callbacks - Thread-safe callback handling with proper locking mechanisms - Prevention of duplicate callback execution when configured - Decorator utilities for easy callback registration - Context manager for controlled callback lifecycle The module centers around the CompilationCallbackHandler class which maintains separate lists for start and end callbacks, manages their execution order, and ensures thread-safety. Utility decorators @on_compile_start and @on_compile_end provide a convenient way to register compilation hooks. Example usage: @on_compile_start def my_start_callback(): print("Starting compilation") @on_compile_end def my_end_callback(): print("Compilation complete") N) Generator)contextmanager) dataclassfield)AnyCallableceZdZdZdZdZdZdS)CallbackTriggerN)__name__ __module__ __qualname__DYNAMO LAZY_BACKWARDTRITON_AUTOTUNINGCUDAGRAPH_RECORDINGh/var/www/tools.fuzzalab.pt/emblema-extractor/venv/lib/python3.11/site-packages/torch/_dynamo/callback.pyr r $s& FMrr c$eZdZUeed<eed<dS) CallbackArgscallback_trigger compile_idN)rrrr __annotations__strrrrrr/s%%%%%OOOOOrrc eZdZUeeZeeegdfed<eeZ eeegdfed<edddZ e ed<ee j dd Ze j ed <d eegdfd eegdffd Zd eegdfd eegdffdZd eegdfd dfdZd eegdfd dfdZded dfdZded dfdZededed edeeffdZddZdS)CompilationCallbackHandler)default_factoryNstart_callbacks end_callbacksrF)defaultinitrepr6_CompilationCallbackHandler__pending_callbacks_counter)r!r%r&;_CompilationCallbackHandler__pending_callbacks_counter_lockcallbackreturnc:|j||S)z Register a callback function to be called when the compilation starts.
