Bug 215793 – Web Inspector: allow url breakpoints to be configured

• Component: Web Inspector
• Status: RESOLVED FIXED

[Devin Rousso]

This would allow developers to do things like:
 - ignore the first N requests
 - evaluate JavaScript whenever a network request is dispatched without pausing

Please rebase and run through EWS prior to landing.

Oops.

Uh, why "text"?

Ditto.

Nit: parameter

Nit: comment and the command name don't match. Please add separate COMPATIBILITY for setXHRBreakpoint and setURLBreakpoint.

.. down here.

> +        if (target.hasCommand("DOMDebugger.removeXHRBreakpoint")) {

Ditto to the above COMPATIBILITY note.

The All Requests breakpoint is a text URL breakpoint (i.e. not regular expression) that has no URL.  I'll special case that in the logging :)

The compatibility comment here is that `setXHRBreakpoint` is what existed before `setURLBreakpoint` replaced it (when `fetch` support was added).

I agree that this is confusing tho, so I'll add separate comments for each :)

Also ensure that modifying the options of a `WI.EventBreakpoint` doesn't enable breakpoints globally.  This matches what is done with `WI.JavaScriptBreakpoint`.

[EWS Watchlist]

This patch modifies the inspector protocol. Please ensure that any frontend changes appropriately use feature checks for new protocol features.
