Обсуждение: cvs and empty directories

I have found cvs creating many directories that I know were removed from
the source tree.  I now use the -P option to cvs update/checkout to
prevent this from happening.

       -P     Prune  (remove)  directories  that  are empty after
              being updated, on checkout, or  update.   Normally,
              an  empty  directory (one that is void of revision-
              controlled files) is  left  alone.   Specifying  -P
              will cause these directories to be silently removed
              from  your  checked-out  sources.   This  does  not
              remove the directory from the repository, only from
              your checked out copy.  Note that  this  option  is
              implied  by  the  -r  or -D options of checkout and
              export.

    The general recommendation that I've received concerning this is
to run:

    cvs -q update -APd

    -q puts it in a quiet mode, so only changes are reported
    -A removes any sticky tags to give you CURRENT sources
    -P Prunes (as above)
    -d creates any new directories required

Unless you have a fast connection to hub.org, another good switch is
"-z3" to enable use of gzip compression on the cvs server connection.
(Marc presumably doesn't need this, but I sure do.)

-z is a "generic" switch that applies to all cvs ops not just update,
so it goes on the left side of the update keyword:

    cvs -q -z3 update -APd

BTW, you can use a ~/.cvsrc file to set default switches and not
have to remember to supply them.  I use

cvs -z3
update -d -P

so I can just type "cvs update".  Any other cvs command that I issue
will also automatically get -z3, which makes cvs a lot more usable
over a modem link.
