![]() When c.elemsize==0 we call raceacquire() and racerelease() as opposed to calling racereleaseacquire() The reason for this change is that, when elemsize==0, we don't allocate a full buffer for the channel. Instead of individual buffer entries, the race detector uses the c.buf as the only buffer entry. This simplification prevents us following the memory model's happens-before rules implemented in racereleaseacquire(). So, instead of calling racereleaseacquire(), we accumulate happens-before information in the synchronization object associated with c.buf. The functionality in this change is implemented in a new function called racenotify() Fixes #42598 Change-Id: I75b92708633fdfde658dc52e06264e2171824e51 Reviewed-on: https://go-review.googlesource.com/c/go/+/271987 Reviewed-by: Dmitry Vyukov <dvyukov@google.com> Reviewed-by: Russ Cox <rsc@golang.org> Run-TryBot: Dmitry Vyukov <dvyukov@google.com> TryBot-Result: Go Bot <gobot@golang.org> Trust: Ian Lance Taylor <iant@golang.org> |
