996221 - Server-sent event sources fail on error if URL contains query parameters

Status: RESOLVED INCOMPLETE

(Core :: DOM: Events, defect)

Description

[ben]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:28.0) Gecko/20100101 Firefox/28.0 (Beta/Release)
Build ID: 20140314220517

Steps to reproduce:

Established a server-sent event source as follows:

        var source = new EventSource("/pilot2/source/?owner=0&shared=&start=&end=&networks=17399&query=");

        source.onmessage = function (event) {
            console.log(event);
            var data = JSON.parse(event.data);
            // Process it etc
        };

        source.onerror = function(event) {
            console.log("Server-sent event error");
        };



Actual results:

Source errors out every time, and then is never re-polled.


Expected results:

The source should be loaded and data parsed. This occurs without problem in Chrome.

Failed to mention: the source URL without query parameters works fine.

Hi Ben,

I tried to test the mentioned issue on latest Firefox release (43.0.4) and latest Nightly (46.0a1) 
but I need more information. Can you please provide a complete URL source so I can try to testes it on my end? Or can you provide a simple test case for this ? Maybe a website like (https://jsfiddle.net/) could help you do this. 

Also, can you please test this on the latest Firefox release (43.0.4) or latest Nightly (46.0a1, https://nightly.mozilla.org/) and tell me if this still reproduces for you ? When doing this please use a new fresh Firefox profile, maybe also in safe mode (https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems). 


Thanks,
Cosmin.

Considering the fact that the reporter did not provided more information on my request, I will mark this issue as resolved - incomplete. 
If you can still reproduce this, feel free to reopen it and provide the requested information.

Thanks,
Cosmin.
