Deadlines

A basic demonstration of using the context package for setting deadlines across subprocesses

Getting Started

To get the context deadline program up and running, make sure you have Go installed and your $GOPATH environment variable set.

To build the program, run:

$ go build

To execute the program, run:

./context

This will print various things to your console. Trace the program and see if you can understanding what is happening!

Editing

By default, we expect to hit the pre-defined context deadline. If you wish to change the timing, edit the time.Sleep() on line 69 to something below 3 seconds. This will let the catch condition (5 pings to google) to succeed and complete the computation defined in the DoSomething() function before the context sends the ctx.Done() signal.
