Introduction

During the demo I will ask you 3 questions:

1. Did we get the expected result?
2. Do we have any race conditions?
3. Did we handle all the errors and shutdowns gracefully?

• RWMutex counter
• Atomic counter

Race detection flag

• Race detection

Concurrency building blocks

• WaitGroup
• Locks
• Atomic
• Channels
• Signals

Examples

• 1. Let's start with a basic example
• 2. Let's try and fix the issues
• 3. Let's make a small change :)
• 4. Finally, something works as expected
• 5. Non-stopping go routines
• 6. Let's handle shutdown gracefully?
• 7. Let's handle shutdown gracefully, for real this time!
• 8. Adding context
• 9. Notify context on signals
