Purpose

Last version of @y/hub contains a fix we need, it fixes the websocket reconnection loop for anonymous user on a read only document sending a keepalive every 20 seconds. In both version 0.10.0 and 0.10.1 breaking changes are introduced, one is impacting us by removing the computePool.patchYdoc function used by the create-ydoc endpoint declated in our yhub server. To fix it, we are doing what the version 0.9.0 was doing and we keep the same behavior.
A new environment variable YHUB_AUTH_TIMEOUT_MS is added to configure the server.authTimeout parameters in the createYhub options

Proposal

  • ⬆️(yhub) upgrade @y/hub to 0.10.1

Walkthrough

The yhub dependencies are upgraded to @y/hub 0.10.1 and @y/y 14.0.0-rc.29. Document creation now parses posted Yjs updates and appends valid updates with generated attribution. The server adds a configurable authentication timeout, applies it to yhub, and reports it in startup logs. Tests cover document creation, permissions, and timeout configuration. Documentation records the schema migration, Redis requirement, worker rollout order, and timeout settings.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Suggested reviewers: maboukerfa

Merge Risk: 🔵 Low · up to cbbdb

The timeout documentation may lead operators to misjudge what the configured limit covers, and the server README undercounts its non-cache settings. These are bounded documentation risks; correct them or merge with owner awareness.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Describe YHUB_AUTH_TIMEOUT_MS as a per-hook limit. The setting limits each authenticate or authorize call, not their combined duration for a connection. The current wording can lead operators to expect a 30-second end-to-end limit.

  • documentation/env.md#L206-L206: replace “whole authentication of a connection” with a description of each hook call.
  • src/helm/impress/README.md#L445-L445: make the same scope correction in the Helm setting table.
  • src/helm/impress/values.yaml#L1192-L1192: correct the source comment used for chart documentation.

Update the tuning section after adding the fifth setting.

The table now has five settings before the cache TTLs. The introduction still counts four, and the validation paragraph still says “All four.” Update both counts so the section clearly includes YHUB_AUTH_TIMEOUT_MS.
