Bug 39810 – new-run-webkit-tests: Support DRT on Chromium-win

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Kent Tamura]

See the discussion in https://bugs.webkit.org/show_bug.cgi?id=39203

Summary:
 DRT protocol needs non-blocking file read.
 Windows Python (non-Cygwin) can't set non-blocking mode by fcntl().
 Cygwin Python can do it.


Possible solutions:
 a) Use Cygwin Python
  I tried it.  I needed some cygpath conversion hacks, but still have mysterious hangup.
 b) Use ctypes
  Can we use ReadFileEx() through ctypes.windll.kernel32?
 c) Implement test_shell protocol for Chromium DRT

I like this refactoring, it makes management of the output code easier. We should probably do the same thing in the DRT proper -- but not today.

 +  # Chromium DRT on non-Windows uses WebKitDriver.
I am curious how platform/win DRT works then?

I don't think it does. AFAIK, it was only a partial implementation that doesn't fully work yet. Copying abarth, who did the port and probably knows best the status.
