Bug 118592 – check-webkit-style: Ignore false positive: Instance of 'Popen' has no 'pid' member

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Brian Holt]

$ Tools/Scripts/check-webkit-style Tools/Scripts/webkitpy/port/common.py
Tools/Scripts/webkitpy/port/common.py:129:  [RunSubprocess] Instance of 'Popen' has no 'pid' member (but some types could not be inferred)  [pylint/E1103] [5]
Tools/Scripts/webkitpy/port/common.py:132:  [RunSubprocess] Instance of 'Popen' has no 'pid' member (but some types could not be inferred)  [pylint/E1103] [5]
Tools/Scripts/webkitpy/port/common.py:133:  [RunSubprocess] Instance of 'Popen' has no 'pid' member (but some types could not be inferred)  [pylint/E1103] [5]

This is clearly an error because Popen does have a pid member: http://docs.python.org/2/library/subprocess.html
Popen.pid
    The process ID of the child process.
    Note that if you set the shell argument to True, this is the process ID of the spawned shell.

As recommended by dpranke in https://bugs.webkit.org/show_bug.cgi?id=101285#c16, this bug is to add the "Instance of 'Popen' has no 'pid' member" to the list of pylint false positives.

The failing test is clearly unrelated to the patch.

This could probably use a new test.
