Test

Perform the following:

1. Download and apply the attached patch.
2. From the top-level WebKit checkout directory, run `Tools/Scripts/run-webkit-tests -1 --debug --no-retry-failures --no-sample-on-timeout LayoutTests/http/tests/xmlhttprequest/testcase.html`.

Then run-webkit-tests dies with the following error:

ValueError raised: invalid literal for int() with base 10: 'null'

and a traceback of the form:

Comment 1 Daniel Bates 2017-08-15 12:04:12 PDT
For some reason removing the following line from testcase.html does not cause run-webkit-test to die with an error:

log(`Content-Length: ${xhr.getResponseHeader('Content-Length2')}`);
Comment 2 Daniel Bates 2017-08-15 12:05:32 PDT
run-webkit-tests seems to be interpreting the test output as HTTP headers.
Comment 3 Jonathan Bedard 2017-08-15 12:06:34 PDT
What do you expect to happen here?  Obviously the exception is bad, but should this test pass?  Should we fail with a text-diff?  Should we restart the test runner?
Comment 4 Daniel Bates 2017-08-15 12:14:30 PDT
Reduced test case:

<html>
<body>
<pre id="console"></pre>
<script>
if (window.testRunner)
    testRunner.dumpAsText();
document.getElementById('console').textContent = 'Content-Length: null';
</script>
</body>
</html>

We expect the test to run successfully and its output should be identical to the output if you ran the test in Safari.
