The cvs.conf portal configuration file maps the NetBSD anoncvs
|
|
respository into the local file system. This means you can cat(1)
|
|
or cp(1) copies of any arbitrary file or revision from the cvs
|
|
server using a local path. Start off like this:
|
|
|
|
# mkdir /p
|
|
# mount -t portal `pwd`/cvs.conf /p
|
|
#
|
|
|
|
The next step is to set up the authentication. The NetBSD anoncvs
|
|
server uses ssh for authentication, so all you need to do is
|
|
|
|
# ssh anoncvs@anoncvs.NetBSD.org
|
|
|
|
and answer 'yes' when it asks you if you want to accept the key.
|
|
Now the NetBSD source tree is close at hand.
|
|
|
|
First, some caveats. File name completion and globbing don't work,
|
|
and diff has difficulties with this since it stat()s the file names
|
|
it's given and gets back more or less meaningless information for
|
|
names under a portal file system.
|
|
|
|
Here's a list of things I've done with this:
|
|
|
|
1) diff one of my files (eg, /etc/security) against the repository
|
|
|
|
% grep NetBSD: /etc/security
|
|
# $NetBSD: security,v 1.52 ...
|
|
% diff -u -< /p/netbsd/src/etc/security,1.52 /etc/security
|
|
[ diffs elided ]
|
|
%
|
|
|
|
Notice the use of the - file given to diff and the input redirection
|
|
so that it will read from stdin instead of opening the file itself.
|
|
This gets around the stat() problem.
|
|
|
|
2) Check out some (or all) versions of a file:
|
|
|
|
% grep NetBSD: /etc/security
|
|
# $NetBSD: security,v 1.52 ...
|
|
% foreach i (`jot 10 43`)
|
|
> cp /p/netbsd/src/etc/security,1.$i /tmp
|
|
> end
|
|
%
|
|
|
|
Presto! Versions 1.43 through 1.52 (jot(1) prints 10 numbers
|
|
starting at 43) of /etc/security are copied into your /tmp directory
|
|
so that you can do arbitrary diffs between any version you like.
|
|
You can use tags instead of revision numbers if you like.
|
|
|
|
3) Instant upgrades. Since cvs always defaults to the head of the
|
|
trunk, you can do this:
|
|
|
|
# cp /p/netbsd/src/etc/security /etc/security
|
|
#
|
|
|
|
to upgrade to the latest and greatest version any time you like,
|
|
or you can do this:
|
|
|
|
# uname -r
|
|
1.5.2
|
|
# cp /p/netbsd/src/etc/security,netbsd-1-5-PATCH002 /etc/security
|
|
#
|
|
|
|
to get rid of any changes you might have made to /etc/security that
|
|
you no longer want.
|
|
|
|
Note that there's some support for the FreeBSD and OpenBSD anoncvs
|
|
service in there as well, but those might be tricky. The FreeBSD
|
|
anoncvs server only offers pserver access, so you'll need to manually
|
|
do a cvs login to make that work. The OpenBSD server seems to move
|
|
around a fair amount, so the CVSROOT value for it will need to be
|
|
updated if that happens again. You might also choose to use
|
|
different servers entirely.
