Please support Kqueue #32

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Try to run on FreeBSD
2. Of course it cannot
3. ???
3. ... No profit :(

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Please provide any additional information below.

If you guys could please support kqueue we could really, really use this at my 
job. It would be a much, much better solution than our cron'd rsyncs.

Thanks and keep up the good work!

I looked at kqueue, unfortunally it does not seem to provide the functionality 
an application like lsyncd needs. It can watch only singular files, not whole 
directories, and all files have to be open to get a handle - which would result 
in funky unwanted effects, if you have an application like lsyncd maintaining 
open handles to all files.

Dovecot on FreeBSD uses Kqueue for watching the files and improve IMAP IDLE 
performance. Do you honestly think it opens every single email file hosted on 
your email system to get a handle? I think you've not looked hard enough at 
what it can do... and providing a Kqueue interface would give OSX and OpenBSD 
support as well.

Please look into this again....

OSX does not have kqueue btw, it has yet another interface "FSEvents", this on 
the others looks like a pretty decent interface for the needs lsyncd has. It 
just hasnt been coded yet.

OSX actually has both...  Here's the OSX man page for kqueue
