1096858 - Browser console doesn't report all messages reported before a window close

Status: RESOLVED DUPLICATE of bug 1107699

(Core :: DOM: Core & HTML, defect)

Description

[Mark Banner (:standard8)]

Adding logging on Loop, we frequently want to check things are happening before a window.close() call.

When doing this, however, the messages aren't displayed on the browser console - they never show up.

Approximate STR would be to open a chat window, and in the page loaded have some code such as:

 console.log("test");
 window.close();

If I put the window.close() in a setTimeout, then the log output happens.

Could this be because we use a timer to queue console.log calls?

Correct. Here is the code:

https://mxr.mozilla.org/mozilla-central/source/dom/base/Console.cpp#589

What we do here is that, when the window is closed we clear the list of pending console messages.
We can change the code, but I prefer to have the patch for bug 1058644 landed before.

Alright, that makes sense.
