08-05-09 - Relacy License Notes

The lock-free code I posted with Relacy has a clarification to the license agreement added. If you have downloaded this please read and make sure you are in compliance. I've copied the added text here :

ADDENDUM ON RELACY LICENSE : (revised 9-14-09)

Relacy is now released under the BSD license :

My work with Relacy is 100% free for any use. However, the original Relacy license still applies to all work product made with Relacy, such as my code above.

The version of Relacy that I built my code with was released under a previous less clear and restrictive license. Dmitry says the new BSD license applies.

    Relacy itself is under LGPL. Any code that you write which directly uses Relacy must be open sourced. This means your threading test harness and the actual lock free algorithms.

    The LGPL means any code you write which directly uses the code covered by the LGPL (by directly I mean not through a DLL) and which you release as a binary must be made available under the LGPL to whomever you gave the binary. If you never publish a binary of the code that uses the LGPL code, you're under no obligation to release the source to it.

    Yeah it's not gonna be exactly LGPL. Stupid licenses. It's so hard
    to just put a reasonable simple license on things.
