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.	2023-02-28 10:18:38 +00:00
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.	2023-01-05 10:21:27 +00:00

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.	2022-12-19 17:39:31 +00:00
