Contributing to the MPS

We are very happy to receive contributions to the Memory Pool System so that we can improve it for everyone.

Review

The MPS is highly engineered and rigorously controlled in order to prevent defects. This approach has lead to an extremely small number of bugs in production since its first commercial use in 1997. There are a fairly large number of rules, both low- and high-level that your code must follow in order to be accepted. These rules are the result of continuous process improvement to prevent defects. Unfortunately, we do not have many of them published at present. We apologise if you find it frustrating that we do not accept your changes as they are.

The style guide in guide.impl.c.format contains basic rules for style.

Licensing

In order for us to accept your contribution, you must agree to the MPS contribution agreement, so that we can continue to commercially license the MPS and thereby fund future development.

I grant Ravenbrook Ltd an irrevocable, perpetual, worldwide, non-exclusive licence to do anything with [your contribution] that I would have the right to do. This includes (but is not limited to):

  1. reproducing it and doing any other act that is restricted by copyright;

  2. the right to sublicence to others the code and any derivative work.

A member of Ravenbrook staff may ask you to expressly (in writing) agree. You just need to reply with “I agree.” We apologise for the inconvenience.

Thank you

Finally, thank you for making the MPS more useful to everyone.
