Now you are pushing pixels. A data-race IS a kind of race condition.
replyMy point is "races" happen all over. In concurrent code, databases, http and pretty much anywhere where you have some kind of timing, not scoped to a unit.
A race condition is an application invariant violation under concurrency, so it has no application-independent definition. A data race is unsynchronized access by two concurrent threads to the same memory location where at least one access is a write. Ergo, the definition of a data race has nothing to do with application logic.
replyI think this should make the distinction between data races and race conditions pretty clear.
A data race is by definition a class of an race condition. This is basic compsci literature, and there is no other way to put it, as even a non programmer can see the similarity.
replyNot sure why you would be that nitpicky for something so trivial?
I find this distinction extremely useful in practice because it explains why a static analyzer like Rust's type checker can prevent all data races but can do nothing about race conditions. (Similarly, a dynamic analyzer like ThreadSanitizer can detect data races but not race conditions, because it knows nothing about application logic.)
