Dmitry S 526a5df157 (core) Manage memory used for websocket responses to reduce the risk of server crashes. ... Summary: - Implements MemoryPool for waiting on memory reservations. - Uses MemoryPool to control memory used for stringifying JSON responses in Client.ts - Limits total size of _missedMessages that may be queued for a particular client. - Upgrades ws library, which may reduce memory usage, and allows pausing the websocket for testing. - The upgrade changed subtle behavior corners, requiring various fixes to code and tests. - dos.ts: - Includes Paul's fixes and updates to the dos.ts script for manual stress-testing. - Logging tweaks, to avoid excessive dumps on uncaughtError, and include timestamps. Test Plan: - Includes a test that measures heap size, and fails without memory management. - Includes a unittest for MemoryPool - Some cleanup and additions to TestServer helper; in particular adds makeUserApi() helper used in multiple tests. - Some fixes related to ws upgrade.
