Andrey Lushnikov 6512ce768d fix(Frame): postpone evaluations until execution context gets created (#1415) ... In Blink, frames don't necesserily have execution context all the time. DevTools Protocol precisely reports this situation, which results in Puppeteer's frame.executionContext() being null occasionally. However, from puppeteer point of view every frame will have at least a default executions context, sooner or later: - frame's execution context might be created naturally to run frame's javascript - if frame has no javascript, devtools protocol will issue execution context creation This patch builds up on this assumption and makes frame.executionContext() to be a promise. As a result, all the evaluations await for the execution context to be created first. Fixes #827, #1325 BREAKING CHANGE: this patch changes frame.executionContext() method to return a promise. To migrate onto a new behavior, await the context first before using it.		2017-11-18 16:27:52 -08:00
