IOSchedulerJob

Deprecated since version 2.36: Use ThreadPool or run_in_thread

class IOSchedulerJob(*args, **kwargs)

Opaque class for defining and scheduling IO jobs.

Methods

class IOSchedulerJob

send_to_mainloop(func: Callable[[...], bool], *user_data: Any) → bool

Used from an I/O job to send a callback to be run in the thread that the job was started from, waiting for the result (and thus blocking the I/O job).

Deprecated since version 2.36: Use invoke().

Parameters:

• func – a SourceFunc callback that will be called in the original thread

• user_data – data to pass to func

send_to_mainloop_async(func: Callable[[...], bool], *user_data: Any) → None

Used from an I/O job to send a callback to be run asynchronously in the thread that the job was started from. The callback will be run when the main loop is available, but at that time the I/O job might have finished. The return value from the callback is ignored.

Note that if you are passing the user_data from io_scheduler_push_job() on to this function you have to ensure that it is not freed before func is called, either by passing None as notify to io_scheduler_push_job() or by using refcounting for user_data.

Deprecated since version 2.36: Use invoke().

Parameters:

• func – a SourceFunc callback that will be called in the original thread

• user_data – data to pass to func
