Implements the full database schema from the README spec and corresponding Go models with relation methods.

Schema (002_tables.sql)

Table Purpose
users Accounts with nick, bcrypt password hash, timestamps
auth_tokens Per-device auth tokens with optional expiry
channels Chat rooms with topic and IRC-style mode flags
channel_members Membership join table with per-user modes (+o, +v)
messages Channel/DM history with JSON meta for extensibility
message_queue Per-user pending delivery queue (unread messages)
sessions Server-held session state with idle timeout
server_links Federation peer configuration

All IDs are UUIDs (TEXT), not auto-increment. Appropriate indexes on foreign keys and common query patterns.

Models (internal/models/)

All models embed Base which provides GetDB() for relation methods:

  • User.Channels(ctx) → channels the user belongs to
  • User.QueuedMessages(ctx) → undelivered messages
  • Channel.Members(ctx) → members with nicks
  • Channel.RecentMessages(ctx, limit) → message history
  • ChannelMember.User(ctx) / ChannelMember.Channel(ctx) → resolve relations
  • AuthToken.User(ctx) / Session.User(ctx) → token/session owner

Also adds Database.Hydrate() as a generic method to inject the DB reference into any model.

Verified

  • All 8 tables created on fresh DB
  • 0 lint issues
  • Builds clean
Implements the full database schema from the README spec and corresponding Go models with relation methods. ## Schema (002_tables.sql) | Table | Purpose | |-------|--------| | `users` | Accounts with nick, bcrypt password hash, timestamps | | `auth_tokens` | Per-device auth tokens with optional expiry | | `channels` | Chat rooms with topic and IRC-style mode flags | | `channel_members` | Membership join table with per-user modes (+o, +v) | | `messages` | Channel/DM history with JSON meta for extensibility | | `message_queue` | Per-user pending delivery queue (unread messages) | | `sessions` | Server-held session state with idle timeout | | `server_links` | Federation peer configuration | All IDs are UUIDs (TEXT), not auto-increment. Appropriate indexes on foreign keys and common query patterns. ## Models (internal/models/) All models embed `Base` which provides `GetDB()` for relation methods: - `User.Channels(ctx)` → channels the user belongs to - `User.QueuedMessages(ctx)` → undelivered messages - `Channel.Members(ctx)` → members with nicks - `Channel.RecentMessages(ctx, limit)` → message history - `ChannelMember.User(ctx)` / `ChannelMember.Channel(ctx)` → resolve relations - `AuthToken.User(ctx)` / `Session.User(ctx)` → token/session owner Also adds `Database.Hydrate()` as a generic method to inject the DB reference into any model. ## Verified - All 8 tables created on fresh DB - 0 lint issues - Builds clean

Schema (002_tables.sql):
- users: accounts with nick, password hash, timestamps
- auth_tokens: per-device tokens with expiry, linked to users
- channels: chat rooms with topic and mode flags
- channel_members: membership with per-user modes (+o, +v)
- messages: channel/DM history with structured JSON meta
- message_queue: per-user pending delivery queue
- sessions: server-held session state with idle timeout
- server_links: federation peer configuration

Models (internal/models/):
- All models embed Base for database access
- Relation methods on models: User.Channels(), User.QueuedMessages(),
  Channel.Members(), Channel.RecentMessages(), ChannelMember.User(),
  ChannelMember.Channel(), AuthToken.User(), Session.User()
- IDs are UUIDs (TEXT), not auto-increment integers
- JSON tags use camelCase per lint rules

All tables verified: migrations apply cleanly, 0 lint issues.

No need for separate migration files before 1.0.0 — there are no
installed versions to migrate. All tables now in one file.

clawbot added 1 commit 2026-02-10 02:49:30 +01:00
All schema changes go into 002_schema.sql until 1.0.0 is tagged.
No migrations during early development phase.

Code Review

1. Duplicated "find by ID" queries

AuthToken.User(), Session.User(), ChannelMember.User(), and ChannelMember.Channel() all have the same SELECT query copy-pasted. Should extract db.GetUserByID(ctx, id) and db.GetChannelByID(ctx, id) lookup methods, then call those from the relation methods.

2. Relation methods return nil on empty results, not empty slices

User.Channels(), Channel.Members(), etc. return nil when there are no rows (because var channels []*Channel starts nil). Callers might get surprised by nil vs [] when marshaling to JSON. Should initialize with make() or []*Channel{}.

3. No timestamps populated on Create methods

CreateUser, CreateChannel, etc. return model structs but don't populate CreatedAt/UpdatedAt — they rely on SQL defaults. The returned model has zero-value times. Should either SELECT back after insert or set time.Now() explicitly.

4. No transactions in the migration runner

Each migration's SQL + recording should be wrapped in a transaction. If a migration partially applies and the INSERT into schema_migrations fails, the database is left in an inconsistent state with no way to retry.

5. QueueMessage ignores LastInsertId error

entryID, _ := res.LastInsertId()

Should check the error.

6. No dequeue/ack for message queue

There's QueueMessage but no DequeueMessages or AckMessages to remove entries after delivery. Needed for the message polling flow.

7. time.Sleep in tests

TestUserQueuedMessages and TestChannelRecentMessages use time.Sleep(10ms) to ensure timestamp ordering. Fragile on slow CI. Could use explicit timestamps or sequential insert ordering instead.

8. Missing lookup methods needed for handlers

  • GetUserByNick() — needed for login
  • GetUserByToken() — needed for auth middleware
  • DeleteAuthToken() — needed for logout
  • UpdateUserLastSeen() — needed for presence tracking

These will be needed as soon as we build the auth handlers.

9. SQLite foreign keys not enabled

SQLite doesn't enforce foreign keys by default. Should run PRAGMA foreign_keys = ON on every new connection. Without this, the ON DELETE CASCADE clauses in the schema are decorative.

10. Overall

The architecture is solid — embedded DB pattern works well, test coverage is good, migration system is clean. Items 1, 3, 4, and 9 are the most impactful to fix before merge.

## Code Review ### 1. Duplicated "find by ID" queries `AuthToken.User()`, `Session.User()`, `ChannelMember.User()`, and `ChannelMember.Channel()` all have the same SELECT query copy-pasted. Should extract `db.GetUserByID(ctx, id)` and `db.GetChannelByID(ctx, id)` lookup methods, then call those from the relation methods. ### 2. Relation methods return nil on empty results, not empty slices `User.Channels()`, `Channel.Members()`, etc. return `nil` when there are no rows (because `var channels []*Channel` starts nil). Callers might get surprised by nil vs `[]` when marshaling to JSON. Should initialize with `make()` or `[]*Channel{}`. ### 3. No timestamps populated on Create methods `CreateUser`, `CreateChannel`, etc. return model structs but don't populate `CreatedAt`/`UpdatedAt` — they rely on SQL defaults. The returned model has zero-value times. Should either SELECT back after insert or set `time.Now()` explicitly. ### 4. No transactions in the migration runner Each migration's SQL + recording should be wrapped in a transaction. If a migration partially applies and the INSERT into `schema_migrations` fails, the database is left in an inconsistent state with no way to retry. ### 5. `QueueMessage` ignores `LastInsertId` error ```go entryID, _ := res.LastInsertId() ``` Should check the error. ### 6.
