The Racket module system utilizes the provide form to manage namespace visibility. While explicit identifier listing ensures strict encapsulation, the all-defined-out shorthand is often used to export all definitions within a module to reduce boilerplate. A design concern arises when a module contains a mix of public API functions and internal helper utiliti
Goal Determine whether Racket's testing ecosystem should supply a built‑in mock connection for racket/db 's connect procedure so that integration tests can run without real database credentials. Constraints and uncertainty The connect function raises an authentication‑required error when username or password are omitted, as documented in racket/db . Teams cu
The racket/sql transaction form begins a DB transaction, runs a thunk, and rolls back on any exception, but it does not intercept DDL statements that trigger an implicit commit in the underlying database. When a statement such as ALTER TABLE is executed inside the thunk, many engines (e.g., PostgreSQL, SQLite, MySQL) commit the transaction before the rollbac
Racket raco pkg configuration missing a lockfile for reproducible builds Goal: ensure that a project built with raco pkg installs the exact same package versions on any machine or at any later time. Constraint: the current deps.rktd format allows version ranges but does not record the resolved versions, and raco pkg has no lockfile mechanism to persist those
Goal Reduce latency spikes that appear only when many concurrent future calls are made in Racket 8.6. Background The future library shares a thread pool whose idle threads are evicted after a period specified by the --thread-evict flag (default 60 s). The Racket manual provides no runtime API to query or change this timeout, so the eviction period is fixed f
Goal Determine whether Racket’s built‑in racket/auth module automatically invalidates credentials once their credential-expiration timestamp passes, or whether this enforcement must be handled entirely by application code. Current Constraints The auth module provides require-credentials to guard handlers, but it returns a generic 401 for both invalid and exp
