Module slow_log 

The slow log: a command or door call that takes more than a second is one JSON line in <supercode home>/logs/slow.jsonl, so slowness reads as bug monitoring (the audit reads it every round). The Node packages write the same lines (@volter/supercode-harness-sdk/slow-log).

{ v: 1, at, kind: "command"|"door"|"call", name, args, ms, outcome, machine, pid, caller, slowest: { step, ms } }. slowest is the longest step the command noted. Writing never fails the command it measures.

Constants

ROTATE_BYTES

The log’s size before it rotates: it and the one rotation before it are all that is kept.

SLOW_MS

Anything slower than this many milliseconds is written.

Functions

note_step

A step of the running command took ms; the longest is the command’s slowest, and every step’s total is in its line’s steps.

path

Where the lines go.

record

One line, when ms is above the bound. caller is asked only then (resolving a caller reads the process table). Answers whether a line was written.

redact_args

The arguments as the log keeps them: secrets replaced, each at most 200 characters.

slowest_step

The longest step noted so far.

timed

Run f as the step step of the running command.
