Supervisor trees for Go.

Suture

Suture provides Erlang-ish supervisor trees for Go. "Supervisor trees" -> "sutree" -> "suture" -> holds your code together when it's trying to die.

This is intended to be a production-quality library going into code that I will be very early on the phone tree to support when it goes down. However, it has not been deployed into something quite that serious yet. (I will update this statement when that changes.)

It is intended to deal gracefully with the real failure cases that can occur with supervision trees (such as burning all your CPU time endlessly restarting dead services), while also making no unnecessary demands on the "service" code, and providing hooks to perform adequate logging with in a production environment.

A blog post describing the design decisions is available.

This module is fully covered with godoc, including an example, usage, and everything else you might expect from a README.md on GitHub. (DRY.)

This is not currently tagged with particular git tags for Go as this is currently considered to be alpha code. As I move this into production and feel more confident about it, I'll give it relevant tags.

Code Signing

Starting with the commit after ac7cf8591b, I will be signing this repository with the "jerf" keybase account.

Aspiration

One of the big wins the Erlang community has with their pervasive OTP support is that it makes it easy for them to distribute libraries that easily fit into the OTP paradigm. It ought to someday be considered a good idea to distribute libraries that provide some sort of supervisor tree functionality out of the box. It is possible to provide this functionality without explicitly depending on the Suture library.
