            Bug ID: 223965
           Summary: REGRESSION(r275204): [GTK][WPE] Several
                    http/tests/contentextensions tests crash
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests

It seems we have a regression on GTK and WPE ports after r275204. The following tests crash now:

Regressions: Unexpected crashes (5)
  http/tests/contentextensions/block-cookies-in-csp-report.py [ Crash ]
  http/tests/contentextensions/block-csp-report.py [ Crash ]
  http/tests/contentextensions/block-everything-unless-domain-redirect.py [ Crash ]
  http/tests/contentextensions/hide-on-csp-report.py [ Crash ]
  http/tests/contentextensions/main-resource-redirect-blocked.py [ Crash ]

I have debugged this and the issue is triggered by the new python scripts.
The HTTP headers they output is different than the previous PHP scripts

See this example with http/tests/contentextensions/main-resource-redirect-blocked.py 

$ printf 'GET /contentextensions/main-resource-redirect-blocked.php HTTP/1.1\r\nHost: localhost\r\n\r\n' | nc localhost 8000
HTTP/1.0 302 Found
Date: Tue, 30 Mar 2021 23:06:50 GMT

Content-Type: text/html

$ printf 'GET /contentextensions/main-resource-redirect-blocked.py HTTP/1.1\r\nHost: localhost\r\n\r\n' | nc localhost 8000
HTTP/1.1 302 Found

0

With the python version it prints different headers (notice the HTTP/1.0 vs HTTP/1.1). It also prints a 0 at the end. It misses the content-length fields and it also doesn't exit intermediately: the connection gets stuck for a few seconds.

I have been trying to modify the main-resource-redirect-blocked.py version to print the same headers than the previous PHP version but so far I had no much luck. The crash is still happening.

The crash log (for http/tests/contentextensions/main-resource-redirect-blocked.py) says this:
