Module util 

Small helpers which modules share that do not depend on each other otherwise.

Constants

SCRATCH 🔒

See with_scratch.

Functions

format_duration 🔒

A duration in whole seconds, with the minutes apart, like 10m, 1m 30s or 45s, for the errors.

sleep_until 🔒

Sleep until the deadline, forever without one.

with_scratch 🔒

Run f on a buffer of len bytes which the thread keeps for all reads which copy what they got out of it right away. The read loops of all containers and attach clients and the runtime calls share it, instead of keeping a buffer each while they wait. It grows to the largest len asked for and holds what the last use left in it.

with_stderr 🔒

Append the stderr of a runtime which failed to its error, unless it wrote nothing. It usually holds the reason.
