Bug 188572 – check-webkit-style incorrectly complaint about Buildbot 1.0 methods

• Status: RESOLVED
• Resolution: CONFIGURATION CHANGED
• Component: Tools / Tests

[Aakash Jain]

check-webkit-style uses code from webkitpy which uses Buildbot 0.8.6p1 (https://trac.webkit.org/browser/webkit/trunk/Tools/Scripts/webkitpy/thirdparty/__init__.py#L197).

0.8.6p1 is the buildbot version used by build.webkit.org (and is very old version). However, in other portion of code (ews-build.webkit.org) we use latest Buildbot. There is significant difference in imports and functions signatures in Buildbot v0.8.6p1 and v1.0. Because of this check-webkit-style incorrectly complains about the code using Buildbot 1.0.

Sample error (https://bugs.webkit.org/show_bug.cgi?id=188498#c2):
ERROR: Tools/BuildSlaveSupport/ews-build/steps_unittest.py:777:  [TestRunWebKit1Tests.test_success] Passing unexpected keyword argument 'state_string' in function call  [pylint/E1123] [5]
ERROR: Tools/BuildSlaveSupport/ews-build/steps_unittest.py:777:  [TestRunWebKit1Tests.test_success] No value passed for parameter 'status_text' in function call  [pylint/E1120] [5]

When we upgrade build.webkit.org to latest Buildbot, this issue will be automatically fixed.

[Aakash Jain]

One solution is to suppress these warnings by adding '-pylint/E1123' and '-pylint/E1120' to https://trac.webkit.org/browser/webkit/trunk/Tools/Scripts/webkitpy/style/checker.py#L118

However, it might suppress some real warnings as well.

I think it's possible to suppress the warning on the line of source code as well...

This works, however this would require adding the pylint disable statement for every line having Buildbot 1.0 related methods/imports. Would be few hundred such lines.

This issue no longer seems to be happening since we moved style queue to new EWS. ews bots have buildbot 1.0+ installed on them.
