Bug 151848 – Web Inspector: Remove untested and unused Worker inspection

• Component: Web Inspector
• Status: RESOLVED FIXED

[Joseph Pecoraro]

* SUMMARY
Remove untested and unused Worker inspection.

* NOTES
The inspector frontend currently doesn't expose UI for debugging workers, so this code has been maintained for a few years without any way for a user to access it. Likewise, some pieces were implemented in V8 and not implemented in JavaScriptCore so it is possible that if tested some pieces would not be fully functional. Rather then keep the code in half-maintained, lets remove it and re-add it when we will focus on adding proper Worker Inspection.

Please update the legacy protocol files as well.

You don't need to modify the vcxproj files, they aren't used by anything.

Why not remove this method entirely?

Might as well nuke this enum too.

Should we sink PageAgentContext into WebAgentContext, or keep this around for the future?

Let's mark WebDebuggerAgent (as well as other similar sibling classes) as final.

Okay.

Yeah, but as long as the files exist I'm going to update them.

I think it would be a good starting point to get console.log working within a Worker without adding complete Worker inspection.

Keep it around. If we can't get to Worker support soon, then maybe, but I'm optimistic.

Where there was a "Web" there was normally a "Page" and "Worker".
