-## 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/fsnotify/fsnotify/issues/1) in the future.

Installing with `go get` makes this easy. - -1. Install from GitHub (`go get -u github.com/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://splice.com/blog/contributing-open-source-git-repositories-go/). - -### Testing - -fsnotify uses build tags to compile different code on Linux, BSD, macOS, 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 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 macOS, 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.

Unless you are creating a library, it is recommended that you copy fsnotify into `vendor/github.com/fsnotify/fsnotify` within your project, and likewise for `golang.org/x/sys`. - -## Contributing - -Please refer to [CONTRIBUTING][] before opening an issue or pull request. - -## Example - -See [example_test.go](https://github.com/fsnotify/fsnotify/blob/master/example_test.go). - -## FAQ - -**When a file is moved to another directory is it still being watched?** - -No (it shouldn't be, unless you are watching where it was moved to). - -**When I watch a directory, are all subdirectories watched as well?** - -No, you must add watches for any directory you want to watch (a recursive watcher is on the roadmap [#18][]). - -**Do I have to watch the Error and Event channels in a separate goroutine?** - -As of now, yes. Looking into making this single-thread friendly (see [howeyc #7][#7]) - -**Why am I receiving multiple events for the same file on OS X?** - -Spotlight indexing on OS X can result in multiple events (see [howeyc #62][#62]). A temporary workaround is to add your folder(s) to the *Spotlight Privacy settings* until we have a native FSEvents implementation (see [#11][]). - -**How many files can be watched at once?** - -There are OS-specific limits as to how many watches can be created: -* Linux: /proc/sys/fs/inotify/max_user_watches contains the limit, reaching this limit results in a "no space left on device" error. -* BSD / OSX: sysctl variables "kern.maxfiles" and "kern.maxfilesperproc", reaching these limits results in a "too many open files" error. - -[#62]: https://github.com/howeyc/fsnotify/issues/62 -[#18]: https://github.com/fsnotify/fsnotify/issues/18 -[#11]: https://github.com/fsnotify/fsnotify/issues/11 -[#7]: https://github.com/howeyc/fsnotify/issues/7 - -[contributing]: https://github.com/fsnotify/fsnotify/blob/master/CONTRIBUTING.md - -## Related Projects - -* [notify](https://github.com/rjeczalik/notify) -* [fsevents](https://github.com/fsnotify/fsevents) - diff --git a/vendor/gopkg.in/fsnotify.v1/fen.go b/vendor/gopkg.in/fsnotify.v1/fen.go deleted file mode 100644 index ced39cb88..000000000 --- a/vendor/gopkg.in/fsnotify.v1/fen.go +++ /dev/null @@ -1,37 +0,0 @@ -// Copyright 2010 The Go Authors.
