Python cancel_protection Examples

Example #1

File: test_core_task.py Project: gottadiveintopython/asyncgui

 async def async_fn():
     task = await ag.get_current_task()
     async with ag.cancel_protection():
         task.cancel()
         await ag.sleep_forever()
     await ag.sleep_forever()
     pytest.fail("Failed to cancel")

Example #2

File: test_core.py Project: gottadiveintopython/asyncgui

 async def async_func(ctx):
     if call_cancel:
         ctx['task'].cancel()
     if protect:
         async with ag.cancel_protection():
             await ag.checkpoint()
     else:
         await ag.checkpoint()

Example #3

async def protect(e):
    import asyncgui
    async with asyncgui.cancel_protection():
        await e.wait()

Example #4

File: test_core_task.py Project: gottadiveintopython/asyncgui

 async def inner_fn(e):
     assert task._cancel_protection == 1
     async with ag.cancel_protection():
         assert task._cancel_protection == 2
         await e.wait()
     assert task._cancel_protection == 1

Example #5

File: test_core_task.py Project: gottadiveintopython/asyncgui

 async def outer_fn(e):
     async with ag.cancel_protection():
         await inner_fn(e)
     await ag.sleep_forever()
     pytest.fail("Failed to cancel")

Example #6

File: test_core_task.py Project: gottadiveintopython/asyncgui

 async def async_fn(e):
     async with ag.cancel_protection():
         await e.wait()
     await ag.sleep_forever()
     pytest.fail("Failed to cancel")

Example #7

async def finish_soon_but_protected(e):
    import asyncgui as ag
    async with ag.cancel_protection():
        await e.wait()
