waitpids

Overview

This is essentially a basic JavaScript node interface for the pact tool.

Check out Nick O'Dell's C implementation: https://github.com/nickodell/pact

N.B. waitpids does not aim to support the exact flags as pact does.

Internally, each Process object is an EventEmitter for signalling.

Usage

Example: require('waitpids')(PID1, PID2) # returns Array of Process objects

• The Array contains exactly what's being monitored. (see Future Work)
• Each Process object has a basic interface, to e.g. cancel monitoring.

This module packages a basic CLI tool: waitpids (wraps exported Function)

Example: waitpids PID1 PID2 # will send SIGTERM to PIDX when PIDY dies

Future Work

N.B. We'd like to do something to avoid polling kill -0 times a million.

The natives folder has some work toward using the waitpid syscall.

Ideally, we'd also leverage the host Object Process from node itself.

The flags that pact supports might also be good waitpid options.

Consider: require('waitpids').call({ signal: 'SIGKILL' }, ...)
