Redux Toolkit's configureStore includes a default serializableCheck middleware designed to ensure that actions and state remain serializable. This is critical for maintaining features like time-travel debugging and state persistence. While the middleware identifies non-serializable values—such as Date objects, Map , Set , or class instances—it currently issu
When Docker Engine runs with userns-remap enabled, container UID 0 maps to a high-numbered host UID, but bind-mounted host files retain their original host ownership. This creates an asymmetry: named volumes are initialized with the remapped root ownership, while bind mounts are not automatically re-owned, often leading to permission mismatches inside the co
When a dependent service uses Compose depends_on long syntax with condition: service_healthy , startup is gated until the dependency's Docker HEALTHCHECK reports healthy. The goal is to decide whether that gating is sufficient for the dependent service to start successfully, or whether it only orders container creation and leaves an application-readiness gap
Cloudflare Load Balancing introduced cookie-based Session Affinity in version 1.3.0, generating an edge-managed _cf_affinity cookie to route subsequent requests to the same origin. The documented behavior indicates that Cloudflare does not propagate SameSite or Secure attributes from the origin’s Set-Cookie header to this affinity cookie, and the Load Balanc
Goal Pass a reference to a Crystal object into a C library callback so the C side can retain and later invoke it, while the Crystal process uses the default Boehm conservative garbage collector. Constraint The Boehm GC does not automatically treat pointers stored in C memory as roots, and Crystal's FFI documentation does not clearly specify a supported API f
Integration Goal Determine whether the physics simulation thread in SourceEngine can be reconfigured to run on a separate core set while maintaining the existing synchronization point where the main thread issues rendering commands after the physics update. Constraints and Uncertainty The engine currently confines physics to a single worker thread, and docum
Goal Prevent a Gulp 4 pipeline from terminating the Node process when an upstream transform stream emits an error, using one error handler on the pipeline. Constraints Stream errors move through the vinyl file system asynchronously, so try/catch cannot capture them. Plugins may swallow or reformat error events, and behavior depends on the plugin and gulp ver
Goal Maintain consistent system-clipboard access via OSC 52 when a tmux session is reattached to different terminal emulators, some of which declare the Ms terminfo capability and others that do not. Constraints and uncertainty tmux 3.2–3.4 uses the static Ms entry in the attached terminal’s terminfo to decide whether to forward OSC 52 sequences when set-cli
RFC 6749 makes refresh-token rotation optional: an authorization server MAY issue a new refresh token, and the client MUST discard the old value when one arrives. The draft OAuth 2.1 revision recommends rotation with reuse detection for public clients, but as a draft it does not impose a binding requirement on deployed servers. Because the core framework doe
