Dan Upton	73b9b407ba	grpc: fix data race in balancer registration (#16229) ... Registering gRPC balancers is thread-unsafe because they are stored in a global map variable that is accessed without holding a lock. Therefore, it's expected that balancers are registered _once_ at the beginning of your program (e.g. in a package `init` function) and certainly not after you've started dialing connections, etc. > NOTE: this function must only be called during initialization time > (i.e. in an init() function), and is not thread-safe. While this is fine for us in production, it's challenging for tests that spin up multiple agents in-memory. We currently register a balancer per- agent which holds agent-specific state that cannot safely be shared. This commit introduces our own registry that _is_ thread-safe, and implements the Builder interface such that we can call gRPC's `Register` method once, on start-up. It uses the same pattern as our resolver registry where we use the dial target's host (aka "authority"), which is unique per-agent, to determine which builder to use.	2 years ago

Dan Upton	d53ce39c32	grpc: switch servers and retry on error (#15892) ... This is the OSS portion of enterprise PR 3822. Adds a custom gRPC balancer that replicates the router's server cycling behavior. Also enables automatic retries for RESOURCE_EXHAUSTED errors, which we now get for free.	2 years ago
Chris S. Kim	831680d2c5	Add custom balancer to always remove subConns (#15701) ... The new balancer is a patched version of gRPC's default pick_first balancer which removes the behavior of preserving the active subconnection if a list of new addresses contains the currently active address.	2 years ago

Dan Upton	b9e525d689	grpc: rename public/private directories to external/internal (#13721) ... Previously, public referred to gRPC services that are both exposed on the dedicated gRPC port and have their definitions in the proto-public directory (so were considered usable by 3rd parties). Whereas private referred to services on the multiplexed server port that are only usable by agents and other servers. Now, we're splitting these definitions, such that external/internal refers to the port and public/private refers to whether they can be used by 3rd parties. This is necessary because the peering replication API needs to be exposed on the dedicated port, but is not (yet) suitable for use by 3rd parties.	2 years ago
