batch-cluster - npm Package Versions

🐞/📦 BatchProcess now end on spurious stderr/stdout, and reject tasks if ending.

📦 Relaxed default for streamFlushMillis to deflake CI

💔/📦 RegExp pass/fail strings are escaped (which could conceivably be a breaking change, hence the major version bump)

📦 Refactored stdout/stderr merging code and added more tests

📦 Added new "taskResolved" event

📦 Rebuild docs

📦 Updated development dependencies

✨ Added on("healthCheckError", err, proc) event

🐞 Fixed process start lag (due to startup tasks not emitting an .onIdle)

🐞 Reworked when health checks were run, and add tests to validate failing health checks recycle children

📦 Rebuild docs

💔 Several fields were renamed to make things more consistent:

• BatchCluster.pendingTasks was renamed to BatchCluster.pendingTaskCount.
• A new BatchCluster.pendingTasks method now matches BatchCluster.currentTasks, which both return Task[].
• BatchCluster.busyProcs was renamed to busyProcCount.
• BatchCluster.spawnedProcs was renamed to spawnedProcCount.

✨ Added support for "health checks" that run periodically on child processes. Both healthCheckCommand and healthCheckIntervalMillis must be set to enable this feature.

✨ New pidCheckIntervalMillis to verify internal child process state is kept in sync with the process table. Defaults to every 2 minutes. Will no-op if idle.

✨ New BatchCluster.childEndCounts to report why child processes were recycled (currently "dead" | "ending" | "closed" | "worn" | "idle" | "broken" | "old" | "timeout" )

📦 Cleaned up scheduling: the prior implementation generated a bunch of Promises per idle period, which was rough on the GC. Use of Mutex is now relegated to tests.

📦 tsconfig now emits ES2018 output and doesn't have downlevelIteration, which reduces the size of the generated javascript, but requires contemporary versions of Node.js.

📦 BatchClusterOptions doesn't mark fields as readonly anymore

📦 Task has a default type of any now.
