Fix unsupported WatchForUpdates and build tags Closes #105. The `go1.1` constraint has been updated to `!go1.3` per https://golang.org/pkg/go/build/#hdr-Build_Constraints and https://github.com/go-fsnotify/fsnotify. Also, the existing call signature for `WatchForUpdates()` in `watcher_unsupported.go` was stale. 2015-05-30 17:44:18 +00:00			`// +build !go1.3 plan9 solaris`
Reload authenticated-emails-file upon update This change extracts the UserMap class from NewValidator() so that its LoadAuthenticatedEmailsFile() method can be called concurrently. This method is called by a goroutine containing a fsnotify.Watcher watching the authenticated emails file. Watching isn't forever aborted when the authenticated emails file disappears. The goroutine will call os.Stat() up to twenty times a second if the file is persistently missing, but that's the pathological case, not the common one. The common case is that some editors (including Vim) will perform a rename-and-replace when updating a file, triggering fsnotify.Rename events, and the file will temporarily disappear. This watcher goroutine handles that case. Also, on some platforms (notably Arch Linux), a remove will be preceded by a fsnotify.Chmod, causing a race between the upcoming fsnotify.Remove and the call to UserMap.LoadAuthenticatedEmailsFile(). Hence, we treat fsnotify.Chmod the same as fsnotify.Remove and fsnotify.Rename. There's no significant penalty to re-adding a file to the watcher.

Fix validator_test hang on Solaris, Plan 9 On these platforms, the `done <- true` statement in during TearDown() was hanging, since the `watcher_unsupported.go` version was never draining the channel.
