-## Issues - -* Request features and report bugs using the [GitHub Issue Tracker](https://github.com/go-fsnotify/fsnotify/issues). -* Please indicate the platform you are using fsnotify on. -* A code example to reproduce the problem is appreciated. - -## Pull Requests - -### Contributor License Agreement - -fsnotify is derived from code in the [golang.org/x/exp](https://godoc.org/golang.org/x/exp) package and it may be included [in the standard library](https://github.com/go-fsnotify/fsnotify/issues/1) in the future. Therefore fsnotify carries the same [LICENSE](https://github.com/go-fsnotify/fsnotify/blob/master/LICENSE) as Go. Contributors retain their copyright, so you need to fill out a short form before we can accept your contribution: [Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual). - -Please indicate that you have signed the CLA in your pull request. - -### How fsnotify is Developed - -* Development is done on feature branches. -* Tests are run on BSD, Linux, OS X and Windows. -* Pull requests are reviewed and [applied to master][am] using [hub][]. - * Maintainers may modify or squash commits rather than asking contributors to. -* To issue a new release, the maintainers will: - * Update the CHANGELOG - * Tag a version, which will become available through gopkg.in. - -### How to Fork - -For smooth sailing, always use the original import path. Installing with `go get` makes this easy. - -1. Install from GitHub (`go get -u github.com/go-fsnotify/fsnotify`) -2. Create your feature branch (`git checkout -b my-new-feature`) -3. Ensure everything works and the tests pass (see below) -4. Commit your changes (`git commit -am 'Add some feature'`) - -Contribute upstream: - -1. Fork fsnotify on GitHub -2. Add your remote (`git remote add fork git@github.com:mycompany/repo.git`) -3. Push to the branch (`git push fork my-new-feature`) -4. Create a new Pull Request on GitHub - -This workflow is [thoroughly explained by Katrina Owen](https://blog.splice.com/contributing-open-source-git-repositories-go/). - -### Testing - -fsnotify uses build tags to compile different code on Linux, BSD, OS X, and Windows. - -Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on. - -To aid in cross-platform testing there is a Vagrantfile for Linux and BSD. - -* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/) -* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder. -* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password) -* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd go-fsnotify/fsnotify; go test'`. -* When you're done, you will want to halt or destroy the Vagrant boxes. - -Notice: fsnotify file system events won't trigger in shared folders. The tests get around this limitation by using the /tmp directory. - -Right now there is no equivalent solution for Windows and OS X, but there are Windows VMs [freely available from Microsoft](http://www.modern.ie/en-us/virtualization-tools#downloads). - -### Maintainers - -Help maintaining fsnotify is welcome. To be a maintainer: - -* Submit a pull request and sign the CLA as above. -* You must be able to run the test suite on Mac, Windows, Linux and BSD. - -To keep master clean, the fsnotify project uses the "apply mail" workflow outlined in Nathaniel Talbott's post ["Merge pull request" Considered Harmful][am]. This requires installing [hub][]. - -All code changes should be internal pull requests. - -Releases are tagged using [Semantic Versioning](http://semver.org/). - -[hub]: https://github.com/github/hub -[am]: http://blog.spreedly.com/2014/06/24/merge-pull-request-considered-harmful/#.VGa5yZPF_Zs diff --git a/vendor/gopkg.in/fsnotify.v1/LICENSE b/vendor/gopkg.in/fsnotify.v1/LICENSE deleted file mode 100644 index f21e54080..000000000 --- a/vendor/gopkg.in/fsnotify.v1/LICENSE +++ /dev/null @@ -1,28 +0,0 @@ -Copyright (c) 2012 The Go Authors.
