node-waitpid2

Originally forked from AvianFlu/node-waitpid changing the behaviour to be more like nature intended.

The waitpid syscall is used to wait for a process to change state.

For terminated child processes, waiting for them releases the resources associated with the child in the process table. If you don't do this, they could remain zombies for ever!

You should implement a blocking loop in your application in order to wait for a child process. You should do this asyncronously by passing WNOHANG as an option and using a timeout to call waitpid until the PID returned is 0 (no child process state changes left). Don't let the waitpid call block the whole thread.

Starting from version 2.0.0 fixed to use the latest node addon/v8 API.

building binary

If a binary is available it will be installed using node-pre-gyp. Binaries are hosted in this repository releases page. The process of building and uploading is as follows:

export NODE_PRE_GYP_GITHUB_TOKEN=<token>
./node_modules/node-pre-gyp/bin/node-pre-gyp configure
./node_modules/node-pre-gyp/bin/node-pre-gyp build
./node_modules/node-pre-gyp/bin/node-pre-gyp package
./node_modules/node-pre-gyp-github/bin/node-pre-gyp-github.js publish
