[REG: 5.10->5.11.1]: QtWebEngine: Using proxy script causes a crash

    XMLWordPrintable

Details

    • Windows

    Description

      When using a script for proxy, it causes webengine to crash in debug mode. This is reproducible with the simplebrowser Qt example, and with a script such as:

      function FindProxyForURL(url, host)
{
   if (isPlainHostName(host)                 ||
       dnsDomainIs(host, "<proper_url>")    ||
       shExpMatch(host, "xxx")   ||
       shExpMatch(host, "*.xxx")   ||
       isInNet(host, "ip", "ip"))
        return "DIRECT";
   else
        return "PROXY proxy.url:8000" ;
}

      Setting a system proxy or a proxy through Qt APIs with the same information does not cause a crash.
