GO Runtime internals documentation

[Dan Partelly]

 Hi all.

 Is there any documentation regarding the internals of GO run-time ? Things like:

- memory allocation strategies; guarantees on alignment and so on
- garbage collection algorithms; host program GC control/ GC guarantees, if any
- scheduler algorithms ; incoming changes in future
- internal of dispatching methods on types.
- internals of interfaces

If there is not such a documentation, is there any plan by GO language team to make such docs available to the end users ? They exist probably internally somewhere.

Thanks.

Some of them are available, but they are subject to change. You shouldn't rely on

any of them.

- scheduler algorithms ; incoming changes in future

Apparently the best one is the source code itself. Unlike in many
enterprise projects, it's not an unreadable mess.

Its a fast moving target:

the run-time & sceduler is currently being redesigned, read here: https://groups.google.com/forum/?fromgroups#!topic/golang-dev/_H9nXe7jG2U

The way memory is allocated and the subsequent Garbage Collection is also being redesigned its on golang-dev for example see this thread: https://groups.google.com/forum/?hl=en&fromgroups#!topic/golang-dev/TWe3tRiZwRk

If you read golang-dev you will also pick up the names of the people working on things, they will be the experts.

Recently, I've started a series of blog posts where I share my own experience of investigating Go source code. I also plan to cover some of the topics that you mentioned. This series can be found here. It might be useful for those who want to start investigating Go internals.
