    Hi! I'm working on nsswitch improvement (during the Google Summer of Code
    program. And, as the deadline is close, I'd like to make some kind of
    release. Actually there would be 2 releases, this is the first.

    This release includes 3 patches. They could be found in the Perforce
    repository:
    http://perforce.freebsd.org/fileDownLoad.cgi?FSPC=//depot/projects/soc2005/nsswitch%5fcached/patches/include.diff&REV=1
    http://perforce.freebsd.org/fileDownLoad.cgi?FSPC=//depot/projects/soc2005/nsswitch%5fcached/patches/libc.diff&REV=1
    http://perforce.freebsd.org/fileDownLoad.cgi?FSPC=//depot/projects/soc2005/nsswitch%5fcached/patches/usr.sbin.diff&REV=1

    or on my mirror:
    http://www.rsu.ru/~bushman/cached/downloads/patchset1/include.diff
    http://www.rsu.ru/~bushman/cached/downloads/patchset1/libc.diff
    http://www.rsu.ru/~bushman/cached/downloads/patchset1/usr.sbin.diff

    Some words on how to use and what it gives:
    include.diff and libc.diff should be applied like that:
    from usr/src: patch -p0 < include.diff,
    from usr/src/lib: patch -p0 < libc.diff

    Features, which would be added by these patches:
    - services-related functions (getserv*) will use nsswitch
    - rpc-related functions (getrpc*) will use nsswitch
    - protocols-related functions (getproto*) will use nsswitch
    - "services", "rpc" and "protocols" sources would be available in
    nsswitch.conf file

    One of my major tasks was to add caching ability to the nsswitch. So,
    these patches also would do it for the following nsswitch sources:
    - passwd
    - group
    - services
    - rpc
    - protocols

    To make caching work, you'll require the caching daemon. It is in the
    usr.sbin patch (should be applied from usr/src: patch -p0 <
    usr.sbin.diff). The caching daemon will be in /usr/sbin folder, its
    configuration and startup files will be in /etc folder. cached(8) and
    cached.conf(5) man pages would be availabe. To enable caching, just add
    "cache" source to the appropriate nsswitch.conf line (the "cache" source
    should be the first source for the database and it can't be used with the
    "compat" source).

    Please try the patches and send me your feedback. I also hope that there
    are no reasons not to merge changes, which were made to libc (they are in
    include.diff and libc.diff) into the CURRENT.
    As for the caching daemon (usr.sbin.diff patch) - I also think that it
    could be merged into the CURRENT.

    In the second release (will happen in 1-2 days - it needs additional
    testing) i'll add caching support for other nsswitch databases (the most
    important is the host database support, I believe).

    With best regards,
    Michael Bushkov
