pyinotify issue
Good day, I just installed pyinotify on my gentoo box. When I test the library through "pyinotify.pv -v /tmp" under root, everything works great, but when I try the same thing under my local user account, I receive the following error: Error: cannot watch . (WD=-1) Not very helpful. I've tried VERBOSE=True mode, but it doens't provide any additional information. I also tried it for a directory in my home folder just to be sure it's not a permission problem, but no luck. Any ideas? Regards, Andre -- http://mail.python.org/mailman/listinfo/python-list

Installing the inotify-tools package allows one to do better troubleshooting. First, my kernel version was too old and did not allow inotify to be executed at user-level. I bumped my kernel up to 2.6.24 and enabled the user-level execution flag. Then pyinotify worked once and failed for all consecutive retries. inotifwatch said that my "maximum number of user watches" was maxed out and that I should increase it under /proc/sys/fs/inotify/ max_user_watches. Something must be wrong, since the max_user_watches was set to 8192. I played around with this setting (sysctl -w fs.inotify.max_user_watches=16843), pyinotify.py and inotifywatch, and finally came the conclusion that pyinotify 0.7.0 was buggy. I got hold of 0.7.1 which seems to have fixed this problem. Hopefully, I'm not speaking too soon. -- http://mail.python.org/mailman/listinfo/python-list

I get this message when I run inotifywatch after a pyinotify operation: Establishing watches... Failed to watch .; upper limit on inotify watches reached! Please increase the amount of inotify watches allowed per user via `/ proc/sys/fs/inotify/max_user_watches'. Strange. I'll keep on troubleshooting. -- http://mail.python.org/mailman/listinfo/python-list
