Bug 180820 – [webkitpy] Add ignore_errors keyword argument to Executive.run_command() for replacing the common pattern of error_handler usage

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Basuke Suzuki]

The error_handler argument of Executive.run_command() method is commonly used for specifying Executive.ignore_error to ignore errors. Is should be more clear by adding ignore_errors=True keyword argument.

[Basuke Suzuki]

Also there's no need to import Executive module just to pass Executive.ignore_error static method if this option is available.

Nit:  I would add " is True" to the end of the message to make it clear:

            assert error_handler is None, "don't specify error_handler if ignore_errors is True"

I would prefer this to be fixed before landing unless you feel strongly about not adding " is True".
