Bug 95334 – Web Inspector: the URL of worker inspector window sometimes is invalid

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Peter Wang]

It's caused by a defect of function "_openInspectorWindow" in "WorkerManager.js". Taking QT port as example, the "window.location.href" is "qrc://../inspector.html", so the url of popup inspector window is "qrc://../inspector.html&dedicatedWorkerId", it causes a problem. To insert a '?' can make it works, the right url is "qrc://../inspector.html?&dedicatedWorkerId".

This can be simplified:
var url = window.location.href
if (!search)
    url += "?";
url += "&dedicatedWorkerId=" + workerId;

You don't need '&' to follow '?', right?

No, I need "&dedicatedWorkerId" to indicate the parameter, but the "url" is not always ended with '?', and it will caused a invalid URL.

The description of the problem

I've upload a picture as a description of this bug. Maybe it shows the problem more clearly.

[Pavel Feldman]

I think I understand the problem clearly. But you code produces

foo.com?&dedicatedWorkerId=...

for "foo.com" href. It should produce

foo.com?dedicatedWorkerId=...

var url = window.location.href + (window.location.search ? "&" : "?") + "dedicatedWorkerId=" + workerId;

would keep it one liner.

Ok.The newest patch can handle the situation if there is a "window.location.hash" in url.

At some point we should make ParsedURL read-write so that one could patch query parameters and serialize it back.
