Dear Gamin devs, I've recently become aware of gamin, which seems to be the answer to an itch I need scratched. I'm looking to add some type of file-change notification system to a server called mt-daapd (http://www.mt-daapd.org/), which streams music using the DAAP protocol used in iTunes (and some compatible players like, I think, Rythmbox). The server needs to know when any of the songs that it is serving change and the current notification mechanism is polling based on a configurable timer.
With that said, I am seeking something similar to FAM that will span multiple OS's and will use whatever event system each OS provides. >From my quick search of the gamin website and mailing list, it appears that gamin will use inotify/dnotify/polling on Linux, kqueue, and something else on NetBSD. So, I have a few questions, if someone doesn't mind spending a moment answering them: 1. On other systems, e.g. OpenBSD, where there might only be support for user-space polling, will the time-out be configurable through gamin? 2. Is there any kind of effort to integrate gamin (or inotify) into other servers that you are aware of? I would be interested to hear about their experiences... 3. Is recursive notifcation supported? For example, I want to monitor, say, "/mnt/storage/", in such a way that any file in that directory, or any subdirectory, is handled without needing to register for each subdirectory. Handling each subdirectory might be a pain, but I am willing to implement it, except that many systems have some kind of limit on the number of open fd's, which would not allow this to scale up as needed. Also, it was brought to my attention that, in FAM, "each process is limited to 1000 active requests at a time". Does this constraint still exist? 4. It seems that some of the developers (specifically, the guy that did the big inotify backend patch) seems to think gamin is only applicable for desktop usage. Should I take from this that gamin is not going to be a good fit for some reason? With all of this said, I apologize if these answers are spelled out somewhere and I'm very appreciative of everyone's work in this field, it seems that this is the only decent project looking to replace FAM.
