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.

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.
