The run-time takes 5+ seconds to respond to Debugger.enable

在列出的 template-master-detail 项目中，使用 tns debug android --start 在 Android Pixel 上重现该延迟。跟踪 runtime 如何处理 Debugger.enable、scriptParsed 和 Debugger.setBreakpointByUrl；当调试器初始化和预设断点在五秒超时前完成时，即表示完成。

Please, provide the details below:

Yes

Tell us about the problem

The run-time takes 5+ seconds to respond to Debugger.enable

Please provide the following version numbers that your issue occurs with:

• CLI: 3.3.1

Please tell us how to recreate the issue in as much detail as possible.

This is reproducible with:
https://github.com/NativeScript/template-master-detail-ts
https://github.com/NativeScript/template-master-detail-ng
https://github.com/NativeScript/template-master-detail-kinvey

against an Android Pixel.

clone https://github.com/NativeScript/template-master-detail-ts

cd template-master-detail-ts
tns platform add android
tns debug android --start

After receiving the Debugger.enable request the run-time would trigger scriptParsed events for all sources in the project (500+ files) first and only then would respond to the Debugger.enable request.

Starting a debug session against any of the listed projects would time out as the JavaScript debugger (Microsoft implementation) in Visual Studio has a non-configurable 5 second timeout on all requests.

In {N} Sidekick the debug session would not timeout but it would still take more than 5 seconds to initialize.

Please note that after receiving a response to Debugger.enable the JavaScript debugger in Visual Studio would start sending Debugger.setBreakpointByUrl for all pre-set breakpoints (again 5s timeout) and if the run-time does not respond to a request the breakpoint would remain inactive.
