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.
To hack on fsnotify, please use [the workflow outlined by Katrina Owen](https://blog.splice.com/contributing-open-source-git-repositories-go/), in short:
### How fsnotify is Developed
1. Install as usual (`go get -u github.com/go-fsnotify/fsnotify`)
* 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'`)
@ -27,15 +40,7 @@ Contribute upstream:
3. Push to the branch (`git push fork my-new-feature`)
4. Create a new Pull Request on GitHub
If other team members need your patch before it is merged:
1. Install as usual (`go get -u github.com/go-fsnotify/fsnotify`)
2. Add your remote (`git remote add fork git@github.com:mycompany/repo.git`)
3. Pull your revisions (`git fetch fork; git checkout -b my-new-feature fork/my-new-feature`)
Notice: For smooth sailing, always use the original import path. Installing with `go get` makes this easy.
Note: The maintainers will update the CHANGELOG on your behalf. Please don't modify it in your pull request.
This workflow is [thoroughly explained by Katrina Owen](https://blog.splice.com/contributing-open-source-git-repositories-go/).
### Testing

* Submit a pull request and sign the CLA as above.

To keep master clean, the fsnotify project uses the "apply mail" workflow outlined in Nathaniel Talbott's post ["Merge pull request" Considered Harmful](http://blog.spreedly.com/2014/06/24/merge-pull-request-considered-harmful/#.VGa5yZPF_Zs).
This requires installing [hub](https://github.com/github/hub). Both version 1 and 2 support `hub am -3`.
