2020-01-09	New sync package.	Ian Gudger
	* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387
2019-11-21	Import and structure cleanup.	Adin Scannell
	PiperOrigin-RevId: 281795269
2019-09-12	Remove go_test from go_stateify and go_marshal	Michael Pratt
	They are no-ops, so the standard rule works fine. PiperOrigin-RevId: 268776264
2019-09-06	Indicate flipcall synchronization to the Go race detector.	Jamie Liu
	Since each Endpoint has a distinct mapping of the packet window, the Go race detector does not recognize accesses by connected Endpoints to be related. This means that this change isn't necessary for the Go race detector to accept accesses of flipcall.Endpoint.Data(), but it is necessary for it to accept accesses to shared variables outside the scope of flipcall that are synchronized by flipcall.Endpoint state; see updated test for an example. RaceReleaseMerge is needed (instead of RaceRelease) because calls to raceBecomeInactive() from unrelated Endpoints can occur in any order. (DowngradableRWMutex.RUnlock() has a similar property: calls to RUnlock() on the same DowngradableRWMutex from different goroutines can occur in any order. Remove the TODO asking to explain this now that this is understood.) PiperOrigin-RevId: 267705325
2019-07-31	Flipcall refinements.	Jamie Liu
	Note that some of these changes affect the protocol in backward-incompatible ways. - Replace use of "initially-active" and "initially-inactive" with "client" and "server" respectively for clarity. - Fix a race condition involving Endpoint.Shutdown() by repeatedly invoking FUTEX_WAKE until it is confirmed that no local thread is blocked in FUTEX_WAIT. - Drop flipcall.ControlMode.

2019-06-21	Add //pkg/flipcall.	Jamie Liu
	Flipcall is a (conceptually) simple local-only RPC mechanism. Compared to unet, Flipcall does not support passing FDs (support for which will be provided out of band by another package), requires users to establish connections manually, and requires user management of concurrency since each connected Endpoint pair supports only a single RPC at a time; however, it improves performance by using shared memory for data (reducing memory copies) and using futexes for control signaling (which is much cheaper than sendto/recvfrom/sendmsg/recvmsg).
