The Go Memory Model - The Go Programming Language

The Go memory model specifies the conditions under which reads of a variable in one goroutine can be guaranteed to observe values produced by writes to the same variable in a different goroutine. Programs that modify data being simultaneously accessed by multiple goroutines must serialize such access. To serialize access, protect the data with channel operations or other synchronization primitives such as those in the sync and sync/atomic packages. If you must read the rest of this document to understand the behavior of your program, you are being too clever. Don't be clever. Go approaches its memory model in much the same way as the rest of the language, aiming to keep the semantics simple, understandable, and useful. This section gives a general overview of the approach and should suffice for most programmers. The memory model is specified more formally in the next section. A data race is defined as a write to a memory location happening concurrently with another read or write to tha
