https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=258010 Bug ID: 258010 Summary: kqueue shortcoming for desktop usage Product: Base System Version: Unspecified Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: email@example.com Moin moin FreeBSDs file monitoring via kqueue/kevent requires files to be opened to be monitored. This has a few draw back which mostly crop up in desktop systems (gnome, kde, ...) that have support for monitoring and indexing the users home directory. Issue 1: A big ~ leads to file handle exhaustion As all files have to be opened the kern.maxfiles sysctl needs to be tuned by users. => desktops won't work out of the box for those users => unnecessary crashes happening on startup of desktop sessions Issue 2: Socket files cannot be monitored As open() cannot be called on socket files, you cannot monitor a socket file for its deletion. Linux's file monitoring seems to be able to support these use cases -- maybe a re-implementation of their file monitoring should be considered inside FreeBSD. An other option would probably be to extend kqueue for these use cases. mfg Tobias -- You are receiving this mail because: You are the assignee for the bug.
