Fix TSFN shutdown reentrance crashes (
e97c75e)
napi_threadsafe_function shutdown could crash if finalization re-entered release logic while resources were being torn down. The fix changes the delete path to mark the TSFN closed before deletion and release resources in a safer order, backed by new shutdown coverage for concurrent and re-entrant release scenarios.
Keep registered FFI callbacks alive with their library (
d44625a)
Callback pointers returned by registerCallback() were just raw addresses, so dropping the JS DynamicLibrary could leave native code calling into freed trampoline memory after GC. The new ownership model keeps the library alive while callbacks are registered and adds tests/docs to ensure callbacks stay valid until explicitly unregistered or the library is closed.
Release queued HTTP/2 memory on stream cancellation (
80a74e1)
Canceled streams were still counted against the session's outbound memory budget, which could block later requests from using available capacity. This change frees that queued-data accounting during stream teardown so canceled uploads stop holding the session back.
