Work-in-progress - Non real-time analyzer UI

[niik]

There's so much stuff that I want to be able to look at when debugging reactive applications. While the LiveView tool works decently for small apps or demo/training purposes it's simply not able to keep up with the amount of information from a highly reactive app such as GitHub for Windows. While talking with @ammeep about this she convinced me that there's some really cool things we could do if we dropped the real-time requirement. This doesn't mean dropping the real time app, I'd like to keep it alive but create a new non-realtime analyzer app that would address the performance problems of a real-time app (no ui thread contention etc).

Not only will this be good for the analysis part, it will also increase performance for apps being instrumented. Rather than communicating with a visualizing app we can now stream all events to disk with minimal overhead.

Design

I'm no where near finished here but one thought I had was to play with a tile-ish app, something like this

Diving deeper would allow for filtering in the timeline

Don't worry. I'll ask some actual designers for input before this is finalized.

Other things

I'd like to be able to detect common inadvisable patterns such as over eager/unnecessary scheduling on the UI thread etc.

Slick!

Cool. I know this is fairly old now (is RxSpy something you're still working on, @niik?), but it's something I've been wanting for a while now. Another benefit to this approach would be that Rx applications running on other platforms (e.g. iOS, Android) could record to the same format, then analysis could take place on a desktop machine.

Not actively unfortunately. I'd love to but I've been busy

Ye! That was definitely one of the goals of this.
