1505806 - maximize_window/stress.py during test verify jobs broken on Windows due to [Errno 10055] An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full

Status: RESOLVED FIXED

(Remote Protocol :: Marionette, defect, P2)

Description

[Andreas Tolfsen ❲:ato❳]

After pushing https://bugzilla.mozilla.org/show_bug.cgi?id=1492499
to autoland, sheriffs alerted me that the test verify job for WPT
(TVw) was failing the new maximize_window/stress.py test only Windows
only.

The test logs contain this clue:

> [Errno 10055] An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full

This seems to be a Window-only issue and instead of backing out the
window manipulation changeset, I’m going to proceed with disabling
this test specifically on Windows until I have time to look at it.

Attachment: bug 1505806: webdriver: throttle window rect calls;

By throttling the Get Window Rect calls we avoid the buffer filling
up on Windows, and avoid errors such as: [Errno 10055] An operation
on a socket could not be performed because the system lacked
sufficient buffer space or because a queue was full
