870588 - 1mb of Pickle in TabParent::SendRealTouchEvent reported by DMD (leaked?)

Status: RESOLVED DUPLICATE of bug 893172

(Core :: IPC, defect)

Description

[Andrew McCreight [:mccr8]]

It looks like we're sending a touch event, creating a Pickle for it, and then somehow leaking the Pickle, as it seems weird for 255 touch events to be live at the same time.  I tried poking around the IPC code a bit, but I didn't see any obvious reason we'd be leaking these, so maybe it isn't actually a leak.

This is another thing in the DMD report from bug 870319.

Pickle?

Attachment: DMD stack

Oops, I meant to attach the DMD log.

Pickle is used to store the serialized version of something when sending it via IPC.

I'm seeing this again in the new DMD report.  Except in this one, there's about 6mb of it.

I'm going to call this fixed by bug 893172.  The followup DMD log only had a few hundred k of pickle stuff.

Really, this is just a duplicate.
