From a187b25aeb5c8c7369a7eccffe4da96feb09dd8a Mon Sep 17 00:00:00 2001 From: Rich Trott Date: Thu, 26 May 2016 20:57:55 -0700 Subject: [PATCH] test: update weak module for gc tests Previous version of weak used for gc tests emitted a warning on OS X. Updating to current version eliminates warning.

These individuals are identified by the WG and their addition to the WG is discussed via GitHub and requires unanimous consensus amongst those WG members participating in the discussion with a quorum of 50% of WG members required for acceptance of the vote. + +_Note:_ If you make a significant contribution and are not considered for commit-access log an issue or contact a WG member directly. + +For the current list of WG members / Collaborators, see the project [README.md](./README.md#collaborators). + +### Consensus Seeking Process + +The WG follows a [Consensus Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making) decision making model. + +Modifications of the contents of the NAN repository are made on a collaborative basis. Anybody with a GitHub account may propose a modification via pull request and it will be considered by the WG. All pull requests must be reviewed and accepted by a WG member with sufficient expertise who is able to take full responsibility for the change. In the case of pull requests proposed by an existing WG member, an additional WG member is required for sign-off. Consensus should be sought if additional WG members participate and there is disagreement around a particular modification. + +If a change proposal cannot reach a consensus, a WG member can call for a vote amongst the members of the WG. Simple majority wins. + + +## Developer's Certificate of Origin 1.1 + +By making a contribution to this project, I certify that: + +* (a) The contribution was created in whole or in part by me and I + have the right to submit it under the open source license + indicated in the file; or + +* (b) The contribution is based upon previous work that, to the best + of my knowledge, is covered under an appropriate open source + license and I have the right under that license to submit that + work with modifications, whether created in whole or in part + by me, under the same open source license (unless I am + permitted to submit under a different license), as indicated + in the file; or + +* (c) The contribution was provided directly to me by some other + person who certified (a), (b) or (c) and I have not modified + it. + +* (d) I understand and agree that this project and the contribution + are public and that a record of the contribution (including all + personal information I submit with it, including my sign-off) is + maintained indefinitely and may be redistributed consistent with + this project or the open source license(s) involved. + + +### WG Members / Collaborators + + + + + + + + + +
