Subject [jira] [Commented] (VFS-536) DefaultFileMonitor will ignore files forever if directory is deleted and recreated
Date Mon, 05 Jan 2015 15:32:34 GMT

    [ https://issues.apache.org/jira/browse/VFS-536?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14264680#comment-14264680

Bernd Eckenfels commented on VFS-536:
-------------------------------------

Hm, I am not so deep into this thats why I havent yet had a look. I know there where some
other FileWatcher bugs here, even some with pending patches. Could you maybe check if any
of those help your problem? 

I am currently busy with finalizing the 2.1 release, but if anybody has a good tested patch
for those (and this) issues, I would be happy to merge it before the release.

> We're using VFS2 in our emacs scala ide https://github.com/ensime/ensime-server
> Unfortunately, I've just discovered that if we watch a directory, e.g. here we are watching
the target directory for class files that are created by a compiler
>  https://github.com/ensime/ensime-server/blob/master/src/main/scala/org/ensime/indexer/FileWatchers.scala#L28
> then if the directory is deleted and recreated (as is done by the SBT scala build tool!)
then monitoring events are ignored forever!
> I can confirm that file watching works fine if individual files are added or removed.
