There are -just a few small guidelines you need to follow. - - -## Contributor License Agreement ## - -Contributions to any Google project must be accompanied by a Contributor -License Agreement. This is not a copyright **assignment**, it simply gives -Google permission to use and redistribute your contributions as part of the -project. - - * If you are an individual writing original source code and you're sure you - own the intellectual property, then you'll need to sign an [individual - CLA][]. - - * If you work for a company that wants to allow you to contribute your work, - then you'll need to sign a [corporate CLA][]. - -You generally only need to submit a CLA once, so if you've already submitted -one (even if it was for a different project), you probably don't need to do it -again. - -[individual CLA]: https://developers.google.com/open-source/cla/individual -[corporate CLA]: https://developers.google.com/open-source/cla/corporate - - -## Submitting a patch ## - - 1. It's generally best to start by opening a new issue describing the bug or - feature you're intending to fix. Even if you think it's relatively minor, - it's helpful to know what people are working on. Mention in the initial - issue that you are planning to work on that bug or feature so that it can - be assigned to you. - - 1. Follow the normal process of [forking][] the project, and setup a new - branch to work in. It's important that each group of changes be done in - separate branches in order to ensure that a pull request only includes the - commits related to that bug or feature. - - 1. Go makes it very simple to ensure properly formatted code, so always run - `go fmt` on your code before committing it. You should also run - [golint][] over your code. As noted in the [golint readme][], it's not - strictly necessary that your code be completely "lint-free", but this will - help you find common style issues. - - 1. Any significant changes should almost always be accompanied by tests. The - project already has good test coverage, so look at some of the existing - tests if you're unsure how to go about it. [gocov][] and [gocov-html][] - are invaluable tools for seeing which parts of your code aren't being - exercised by your tests. - - 1. Do your best to have [well-formed commit messages][] for each change. - This provides consistency throughout the project, and ensures that commit - messages are able to be formatted properly by various git tools. - - 1. Finally, push the commits to your fork and submit a [pull request][]. - -[forking]: https://help.github.com/articles/fork-a-repo -[golint]: https://github.com/golang/lint -[golint readme]: https://github.com/golang/lint/blob/master/README -[gocov]: https://github.com/axw/gocov -[gocov-html]: https://github.com/matm/gocov-html -[well-formed commit messages]: http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html -[squash]: http://git-scm.com/book/en/Git-Tools-Rewriting-History#Squashing-Commits -[pull request]: https://help.github.com/articles/creating-a-pull-request diff --git a/vendor/github.com/google/gofuzz/LICENSE b/vendor/github.com/google/gofuzz/LICENSE deleted file mode 100644 index d64569567..000000000 --- a/vendor/github.com/google/gofuzz/LICENSE +++ /dev/null @@ -1,202 +0,0 @@ - - Apache License - Version 2.0, January 2004 - http://www.apache.org/licenses/ - - TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION - - 1.
