Move first-time setup after transaction apps/meteor/server/lib/callbacks.ts, apps/meteor/server/lib/users/setUsername.ts |
afterCreateUser is now an event-like callback with a void return type. Username validation no longer accepts the silenced-channel parameter. First-time setup runs after a successful transaction. |
Validate first-time setup behavior apps/meteor/tests/unit/server/lib/users/setUsername.spec.ts, .changeset/proud-pears-wait.md |
Unit tests cover callback execution, default-channel joining, and existing username changes. The patch changeset documents the fix. |
Estimated code review effort: 2 (Simple) | ~10 minutes
Merge Risk: 🔵 Low · up to b21a7
The change makes first-time username assignment join default channels and invoke the creation callback. If joining a default channel fails, later setup actions may not run, so the PR is mergeable with explicit owner awareness or follow-up for failure handling.

In `@apps/meteor/server/lib/users/setUsername.ts`:
- Around line 153-154: Update the first-time user setup around
joinDefaultChannels so a rejected channel join is handled independently and does
not prevent callbacks.run('afterCreateUser', user), invite-room joining, or
user.nameChanged from executing. Preserve onceTransactionCommitedSuccessfully’s
error logging while ensuring the remaining setup continues after the channel
failure.
- Line 31: Update the UserConverter existing-user username-update flow to call
joinDefaultChannels only when skipDefaultChannels is not enabled, and isolate
any joinDefaultChannels failure so invite-room joining and the user.nameChanged
broadcast still execute. Remove the implementation comments at the specified
locations.

On a brand new workspace the admin created by the setup wizard is not a member of
#general— the room is created withdefault: truebut hasusersCount: 0and no subscription. The same happens to OAuth, SAML and LDAP users with no username mapping, who pick a username on the Register Username screen. Both flows also skip theafterCreateUsercallback.An account can be created without a username, and
Accounts.insertUserDocskips the join in that case by design — the account is not usable yet. Joining happens instead when the user is assigned their first username, the very next request in the wizard and possibly much later on the Register Username screen, and that code lived insetUsernameWithValidation, behind thesetUsernameMeteor method both flows called. PR #36146, a deprecation chore, swapped that method forPOST /v1/users.updateOwnBasicInfoinSetupWizardProvider.tsxandRegisterUsername.tsx, and that endpoint routes tosaveUserProfile→saveUserIdentity→_setUsername: the username is written, butsetUsernameWithValidationis never reached. Nothing was deleted — the block is still there, which is whyPOST /v1/users.registerkeeps working; two callers just started using a different door.The fix moves
joinDefaultChannelsandafterCreateUserone layer down, into_setUsername, which every username assignment converges on —users.registerthroughsetUsernameWithValidation, and both regressed flows throughsaveUserProfile, all of them viasaveUserIdentity.setUsernameWithValidationalso loses its now-unusedjoinDefaultChannelsSilencedparameter, andafterCreateUsernow receives the user with the username populated instead of the pre-save snapshot.Issue(s)

#general. Before the fix,rocketchat_subscriptionforrid: "GENERAL"is empty and the room hasusersCount: 0.#general.Regression checks:
users.registerstill joins exactly once,users.createis unchanged, and changing an existing username creates no new subscription.Further comments
_setUsernameand notsaveUserProfile(the candidate fix on the issue):_setUsernameis already where the first-username side effects live, and all of them already fire on admin edits today, so the "never the previous behaviour" argument does not hold.saveUserProfilewould also add a third copy of the rule and leave future callers ofsaveUserIdentityregressing the same way.saveUserIdentity— happy to add here if preferred.Summary by CodeRabbit
