Bug 61040 – Web Inspector: initial showing of heap snapshot doesn't provide any feedback on waiting time

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

[Ilya Tikhonovsky]

there are 4 stages of making detailed heap snapshot.
1) snapshoting
2) loading...
3) parsing...
4) a stage between parsing and the moment when snapshot items appear in the list.

it'd be nice to have a text for the fourth stage and a kind of progress indicator for all the stages.

The action will not be called if the message is already visible. r- for this.

Really good catch! Fixed.

Why no use a shorter notation: instance.unlistenAndHide.bind(instance, listenObject, listenEvent)? Also, you don't need to pass instance as the third parameter since you pass it in bind.

Fixed.
The third parameter is used by Object.addEventListener / removeEventListener pair of functions to identify the listener, as they can't extract the event handler from the closure passed.
