nlmixr2utils 0.3.1

• Fixed rawResultsRow()’s minimization_successful column, which previously reported failure (0) for essentially every real fit. The fallback heuristic treated any non-empty fit$message as a failure signal, but nlmixr2est fit objects populate $message with the optimizer’s exit text on success too (e.g. "Normal exit from bobyqa"), and never carry the $minimization_successful field the primary check looked for. The fallback now uses fit$convergence (0 = success, mirroring the underlying optimizer’s ierr/status code) instead.

nlmixr2utils 0.3

• .withWorkerPlan() now guards against requesting more parallel OS threads than the machine has: whenever more than one worker is involved, it checks the effective worker count (from workers, or from the ambient future plan when workers = NULL) times the effective rxode2 thread count per worker (from the new rxThreads argument, or from rxode2::getRxThreads() when unspecified) against the total physical core count (parallel::detectCores()), and aborts with a clear message before evaluating anything if the product would exceed it. A single worker is never subject to this check.
• Breaking change: because rxode2’s own default thread count was never designed with the assumption that multiple worker processes would each run a copy of it, existing calls to .withWorkerPlan() with workers > 1 or workers = "auto" that do not also set rxThreads will, on most real multi-core machines, now abort where they previously ran silently oversubscribed. Set rxThreads explicitly (e.g. rxThreads = 1) to restore the prior behavior.
• New resolveRxThreads(workers, rxThreads) resolves the effective rxode2 thread count for a given workers/rxThreads combination, validating both arguments.
• .plap() gained an rxThreads argument that propagates the resolved thread count into every task (whether it runs in the main process or a multisession worker) and restores each worker’s own prior setting afterward, so persistent workers reused across calls don’t leak state between them. .withWorkerPlan() also best-effort broadcasts the resolved thread count to every worker in the active plan on its own, so callers that don’t route rxThreads through their own .plap() calls still get an accurate thread count applied.

nlmixr2utils 0.2

• Promoted the shared raw-results and run-cache helper APIs to stable status now that downstream bootstrap and SIR packages use the common output, restart, and seeding infrastructure.

nlmixr2utils 0.1

• Added experimental shared raw-results helpers (rawResultsSchema(), rawResultsRow(), writeRawResults(), readRawResults(), parseRawResultsParams(), and setupRawResultsFilter()) plus run-cache helpers (resolveRunDir(), readRunState(), writeRunState(), taskCache(), pendingTasks(), withRunSeed(), and deriveFitName()) for downstream nlmixr2 extension packages.

• Initial package largely cloned from nlmixr2extra, providing shared worker-plan helpers, covariance utilities, equation-printing methods, reexports, and the theoFitOde package data used by the new extension packages.
