batch-cluster - npm Package Versions

💔 Dropped official support for Node v16, which is EOL.

💔 Several methods, including BatchCluster#pids() were changed from async to sync (as they were needlessly async).

📦 A number of timeout options can now be validly 0 to disable timeouts:

• spawnTimeoutMillis
• taskTimeoutMillis

📦 Added eslint @typescript-eslint/await-thenable rule and delinted.

📦 Updated development dependencies and rebuilt docs

🐞 pidExists now handles EPERM properly (previous implementation would mischaracterize pids as being dead due to insufficient permissions)

📦 Updated development dependencies and rebuilt docs

💔/✨ pidExists and killPid are no longer async, as process management is now performed via node:process.kill(), instead of forking ps or tasklist.

📦 Updated development dependencies and rebuilt docs

🐞 Fix support for zero value of maxProcAgeMillis

📦 Updated development dependencies and rebuilt docs

🐞 Fix unref is not a function

📦 Updated development dependencies and rebuilt docs

✨ If healthCheckCommand is set and any task fails, that child process will have a health check run before being put back into rotation.

📦 Updated development dependencies and rebuilt docs

🐞 BatchCluster#maybeSpawnProcs in prior versions could spawn too many processes, especially if process startup was slow. Heuristics for when to spawn new processes now take into account pending task length and processes busy due to initial setup.

📦 BatchCluster.vacuumProcs returns a promise that is only fulfilled after all reaped child processes have completed BatchProcess.#end.

📦 BatchProcess.whyNotHealthy can now return startError.

📦 childEnd is now emitted only after the child process exits

📦 BatchCluster.#onIdle is debounced during the same event loop

📦 Added startup and shutdown spec assertions

📦 Updated development dependencies and rebuilt docs

📦 Add Rate.msSinceLastEvent

📦 Adjusted streamFlushMillis to remove onTaskData errors in CI.
