Objects derived from this class monitor a collection of subprocesses and report their termination or interruption by a signal. New callbacks are registered with .add_child_handler(). Starting a new process must be done within a 'with' block to allow the watcher to suspend its activity until the new process if fully registered (this is needed to prevent a race condition in some implementations). Example: with watcher: proc = subprocess.Popen("sleep 1") watcher.add_child_handler(proc.pid, callback) Notes: Implementations of this class must be thread-safe.

This child watcher polls process file descriptors (pidfds) to await child process termination. In some respects, PidfdChildWatcher is a "Goldilocks" child watcher implementation. It doesn't require signals or threads, doesn't interfere with any processes launched outside the event loop, and scales linearly with the number of subprocesses launched by the event loop. The main disadvantage is that pidfds are specific to Linux, and only work on recent (5.3+) kernels. c | S r r r s r r zPidfdChildWatcher.__enter__ r c y r r )r+ exc_type exc_value exc_tracebacks r r zPidfdChildWatcher.__exit__ r c yrF r r s r rz zPidfdChildWatcher.is_active rq r c y r r r s r r1 zPidfdChildWatcher.close r r c y r r r s r r z PidfdChildWatcher.attach_loop r r c t j }t j | }|j || j |||| y r )r get_running_loopr! pidfd_openr _do_wait)r+ r rU rV r pidfds r r} z#PidfdChildWatcher.add_child_handler s: &&( c" sE8TJr c $ t j }|j | t j |d \ }}t | }t j | |||g| y # t $ r d}t j d| Y Cw xY w)Nr zJchild process pid %d exit status already read: will report returncode 255) r r r r! waitpidr" ChildProcessErrorr rf r1 ) r+ r r rU rV r _r$ r s r r zPidfdChildWatcher._do_wait s &&( E" 8 3*IAv 07J j(4( !
