initialize() still shares one in-flight #doInitialize() promise among concurrent callers, then awaits it. On rejection it sets #initPromise to undefined and rethrows, so a later call starts a new attempt. After a successful initialization, further calls return without issuing more SQL. Tests cover a non-race statement timeout that fails on the first statement, a following initialize() that reaches the database and then stays cached, and two overlapping callers that share one rejection before a subsequent call begins again. The @fedify/postgres changelog records the fix. Fixes fedify-dev#1268 Assisted-by: AI

Thanks for looking into #1268 and putting together a fix. I'm going to close this pull request for process reasons, not because the change is wrong—the fix itself looks like it's on the right track. Fedify's contribution guide asks first-time contributors to get an accepted issue and a maintainer assignment before opening a pull request. AI-assisted pull requests from outside contributors may only address accepted issues. Nobody assigned #1268 to you, so this PR arrived before a maintainer had a chance to steer the work. There's also a concrete problem with the submission: the base branch is wrong. This is a bug fix, and per the branch policy it must target the oldest maintenance branch that contains the bug. That is None of this is meant to discourage you. This one is urgent and needs a patch release today, so I'll take care of the fix myself. If you'd still like to contribute, please pick another issue from the tracker, comment on it, and wait for a maintainer to assign it before opening a pull request—that's the path that lets us accept your work. Thanks again. |

initialize() still shares one in-flight #doInitialize() promise among concurrent callers, then awaits it. On rejection it sets #initPromise to undefined and rethrows, so a later call starts a new attempt. After PostgresMessageQueue.initialize() fails once, that same instance keeps failing and sends no further SQL. enqueue(), getDepth(), and listen() all wait on initialization, so a transient database error leaves the queue unusable until the application constructs a new one.
