881191 - Lots of IPCs caused by mozilla::dom::PContentChild::SendScriptError

Status: RESOLVED DUPLICATE of bug 795534

(Core :: IPC, defect)

Description

[Ting-Yuan Huang]

When opening Twitter on Firefox OS, script errors are repeatedly detected and sent to parent process for logging. Unfortuanately, many of the errors occured in extremely long lines. There are about 34 MBytes sent when opening Twitter, although parent process cuts it off before printing it out. Anyway, it puts unecessary overheads to IPCs. Should we put some limitations on the erring source lines sent or just not show them?

Hi Kyle and Justin, any comments? I'd like to cut the lines off earlier in ConsoleListener::Observe()

We've had lots of problems with the console listener sending very long messages.  Go for it.
