To hack on fsnotify:

  1. Install as usual (go get -u
  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
  3. Push to the branch (git push fork my-new-feature)
  4. Create a new Pull Request on GitHub

For other team members:

  1. Install as usual (go get -u
  2. Add your remote (git remote add fork
  3. Pull your revisions (git fetch; git checkout -b my-new-feature fork/my-new-feature)

Notice: Always use the original import path by installing with go get.


fsnotify uses build tags to compile different code on Linux, BSD, OS X, and Windows. Our continuous integration server is only able to test on Linux at this time.

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 make cross-platform testing easier, we are providing a Vagrantfile for Linux and BSD.

  • Install Vagrant and VirtualBox
  • 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)
  • Once setup, you can run the test suite on a given OS with a single command vagrant ssh bsd -c 'go test ./...'.
  • When you're done, you will want to halt or destroy the vagrant boxes.

Notice: fsnotify file system events won't work on shared folders. The tests get around this limitation by using a tmp directory, but it is something to be aware of when logging in with vagrant ssh linux to do some manual testing.

Right now we don't have an equivalent solution for Windows and OS X, but there are Windows VMs freely available from Microsoft.
