scistacklog

The shared logging facade for every scistack layer. This is the lowest-level package in the stack — it has no dependencies, and every other layer (scifor, scidb, sciduckdb, …) emits through it or through a plain logging.getLogger("<layer>") child logger that it covers.

Design

One Log call, two destinations with independent levels:

console (stderr) — a concise pipeline narrative for the person running the pipeline. Time-only timestamps; level prefix only at WARN and above.

14:32:06 [scifor] for_each(compute_psd) — 120 iterations: subject=12 values [s01,…,s12]
14:33:15 [scifor] WARN: iteration failed: subject=s03, session=2 — ValueError: bad channel count

file (scidb.log next to the database, pointed via Log.set_path, done automatically by scidb.configure_database()) — the run document. One record per line: date + millisecond timestamp, level, originating layer.

2026-07-07 14:32:06.001 INFO  [scifor] for_each(compute_psd) — 120 iterations: subject=12 values [s01,…,s12]
2026-07-07 14:33:20.100 INFO  [scidb] [timing] save_batch(PSD): 114 items, 12 schemas, 0.412s

Both sinks default to INFO. DEBUG detail (per-iteration lines, timing phase tables, framework internals) is opt-in:

from scistacklog import Log

Log.set_level("DEBUG", sink="file")   # full detail in the file only
Log.set_level("DEBUG")                # both sinks

or set the SCIDB_LOG_LEVEL environment variable (applies to both sinks), or pass -v to the scidb CLI.

Usage

from scistacklog import Log

Log.info("for_each(compute_psd) — 120 iterations", layer="scifor")
Log.debug("combo detail: %s", combo, layer="scifor")
Log.error("save failed", layer="scidb", exc_info=True)

layer must be one of scistacklog.LAYERS (scidb, scifor, sciduck, scihist, scilineage, scistack, scistack_gui, matlab).

Contracts

caplog: level filtering happens on the two handlers, never on the loggers — every record propagates to the root logger, so pytest's caplog captures everything regardless of sink levels. Log.*(...) with the default layer emits on logger "scidb", unchanged from the historical implementation.
MATLAB: scimatlab's +scidb/Log.m delegates to this class via py.scidb.log.Log.* (a re-export shim in scidb). The numeric level scale (DEBUG=0 … ERROR=3) and positional call shapes are frozen for that bridge.
