Runtime turn operation binding schema v
Error message
Runtime turn operation binding schema v{} is newer than supported v{} What it means
RuntimeTurnOperationBinding::validate compares the binding record's schema_version to TURN_OPERATION_BINDING_SCHEMA_VERSION (currently 1). A binding stamped by a newer binary is refused, along with further checks on thread id and other fields. This keeps claim/lock metadata interpretable by the running process.
Solutions
- Upgrade to the newer build that wrote the binding.
- Delete the stale binding file once no process owns the turn operation, then retry the claim.
- Use one runtime store directory per app version.
- Check schema_version in the binding JSON; a value of 1 or less with this error indicates a different problem (corrupt file) to investigate separately.
Example fix
// before: stale binding blocks startup
$ rm ~/.local/share/codewhale/runtime/turn-bindings/<op-id>.json
// after (programmatic)
match binding {
Ok(b) => use_binding(b),
Err(e) if e.to_string().contains("newer than supported") => {
remove_stale_binding(&path)?; // only if no live owner
retry_claim(key)?;
}
Err(e) => return Err(e),
} Defensive patterns
Strategy: try-catch
Validate before calling
let v: serde_json::Value = serde_json::from_str(&std::fs::read_to_string(&binding_path)?)?;
if v["schema_version"].as_u64().unwrap_or(1) > TURN_OPERATION_BINDING_SCHEMA_VERSION as u64 {
eprintln!("binding written by newer build; remove only if no live owner");
} Type guard
fn binding_supported(b: &RuntimeTurnOperationBinding) -> bool {
b.schema_version <= TURN_OPERATION_BINDING_SCHEMA_VERSION
} Try / catch
match binding.validate() {
Ok(()) => proceed(binding),
Err(e) if e.to_string().contains("newer than supported") => {
if !owner_alive(&binding) { remove(&path)?; retry_claim(key)?; }
}
Err(e) => return Err(e),
} Prevention
- Remove leftover bindings only after confirming the owning process is dead.
- Avoid sharing one runtime directory between different app versions.
- Upgrade before resuming sessions created by a newer build.
When it happens
Trigger: Validating a persisted turn-operation binding (claim/lock file) whose schema_version is greater than TURN_OPERATION_BINDING_SCHEMA_VERSION — i.e., the file was written by a newer release that bumped the binding schema.
Common situations: Downgrading Codewhale while leftover binding files from a newer version remain in the store; two versions of the app sharing one runtime directory; a crash left a binding that the old binary cannot validate.
