A lot of different clients use console.debug as a message channel from
page to protocol client. console.debug is a little slow and not
designed for this use case.
This CL introduces new method: Runtime.installBinding. This method
installs binding function by given name on global object on each
inspected context including any context created later.
Binding function takes exactly one string argument. Each time when
binding function is called, Runtime.bindingCalled notification is
triggered and includes passed payload.
Binding function survives page reload and reinstalled right after
console object is setup. So installed binding can be used inside
script added by Page.addScriptToEvaluateOnNewDocument so client may do
something like:
Runtime.installBinding({name: 'send'});
Page.addScriptToEvaluateOnNewDocument({source: 'console.debug = send'});
.. navigate page ..
In microbenchmark this function is ~4.6 times faster then
console.debug.
