Cherry-pick of #28522 (
26de6140fb) ontorelease/2.35.Adds
CODER_DISABLE_WORKSPACE_AGENT_CONTEXT_SYNC/--disable-workspace-agent-context-sync. When set,PushContextStaterejects agent context pushes with a dRPCUnimplementedcode before any validation or database work; deployed agents translate that intoErrPushUnimplementedand stop their push loop for the life of the connection. This gives large deployments a server-only kill switch for context sync database write load, with no agent updates or workspace restarts required.Two conflicts resolved relative to the original commit:
coderd/workspaceagentsrpc.go:release/2.35assignsContextDirtyMarker: api.chatDaemondirectly (the nil-guarded local was introduced later onmain); kept the branch's form and addedContextSyncDisabledalongside it.docs/admin/setup/configuration-reference.md: dropped; this generated doc does not exist onrelease/2.35.Validated on this branch:
go build,TestPushContextState(unit),TestWorkspaceAgentPushContextState*(end-to-end over real dRPC), CLI and enterprise golden-file tests, full pre-commit hooks.
