Deadlocks

Explore the concept of deadlocks in Go concurrency programming. Understand the four Coffman conditions that lead to deadlocks, how they block processes, and the mechanisms Go uses to detect when all goroutines are stuck. This lesson prepares you to avoid deadlock scenarios in your concurrent Go applications.

What is a deadlock?

A deadlock occurs when all processes are blocked while waiting for each other and the program cannot proceed further.

Let’s have a look at the conditions for a deadlock to occur:

Coffman Conditions

There are four conditions, known as the Coffman Conditions, that must be present simultaneously for a deadlock to occur:

Mutual Exclusion

A concurrent process holds at least one ...
