<H2><A NAME="s12">12. CVS</A></H2>
|
|
|
|
<P>CVS stands for "Concurrent Versions System" and the CVS for DXSpider is held
|
|
at
|
|
<A HREF="http://www.sourceforge.net">Sourceforge</A>. This means
|
|
that it is possible to update your DXSpider installation to the latest
|
|
sources by using a few simple commands.
|
|
<P>
|
|
<P>THIS IS NOT FOR THE FAINT HEARTED!!! ONLY DO THIS IF YOU HAVE A TEST
|
|
INSTALLATION OR ARE WILLING TO HAVE YOUR CLUSTER CRASH ON YOU!!!
|
|
THIS MUST BE CONSIDERED AT LEAST BETA TESTING AND MAYBE EVEN ALPHA!!
|
|
YOU HAVE BEEN WARNED!!!
|
|
<P>
|
|
<P>DID I MENTION..... ONLY DO THIS IF YOU ARE WILLING TO ACCEPT THE
|
|
CONSEQUENCES!!!
|
|
<P>
|
|
<P>I am of course assuming that you have a machine with both DXSpider and
|
|
Internet access running.
|
|
<P>
|
|
<P>BEFORE YOU EVEN CONSIDER STARTING WITH THIS MAKE A BACKUP OF YOUR
|
|
ENTIRE SPIDER TREE!!
|
|
<P>
|
|
<P>Assuming you are connected to the Internet, you need to login to the
|
|
CVS repository and then update your Spider source. There are several
|
|
steps which are listed below ...
|
|
<P>
|
|
<P>First login as the user <EM>sysop</EM>. Next you need to connect to the CVS
|
|
repository. You do this with the command below ...
|
|
<P>
|
|
<PRE>
|
|
cvs -d:pserver:anonymous@cvs.DXSpider.sourceforge.net:/cvsroot/dxspider login
|
|
</PRE>
|
|
<P>You will get a password prompt. Simply hit return here and your machine should
|
|
return to a normal linux prompt.
|
|
<P>
|
|
<P>What happens next depends on whether you have an existing installation that
|
|
you want to update with the latest and greatest or whether you just want
|
|
to see what is there and/or run it on a new machine for testing.
|
|
<P>If you are installing Spider from CVS then change directory to /home/sysop
|
|
<P>If you are wanting to update Spider then cd to /tmp
|
|
<P>
|
|
<P>The next step will create a brand new 'spider' directory in your current
|
|
directory.
|
|
<P>
|
|
<PRE>
|
|
cvs -z3 -d:pserver:anonymous@cvs.DXSpider.sourceforge.net:/cvsroot/dxspider co spider
|
|
</PRE>
|
|
<P>This command is all on one line.
|
|
<P>
|
|
<P>Hopefully your screen should show you downloading files. The -z3 simply compresses
|
|
the download to improve speed.
|
|
When this has finished, you will have exactly the same as if you had untarred a full
|
|
tarball PLUS some extra directories and files that CVS needs to do the magic that
|
|
it does.
|
|
<P>
|
|
<P>Now if you are doing a new installation, that's it. Carry on as if you have
|
|
just downloaded and untarred the lastest tarball.
|
|
<P>
|
|
<P>If you want to upgrade your current installation then do this ...
|
|

<BLOCKQUOTE><CODE>
|
|
<PRE>
|
|
tar cvfz /tmp/s.tgz spider
|
|
cd /
|
|
tar xvfzp /tmp/s.tgz
|
|
</PRE>
|
|
</CODE></BLOCKQUOTE>
|
|
<P>This is assuming you downloaded to the /tmp directory of course.
|
|
<P>
|
|
<P>NOTE: the 'p' on the end of the 'xvfz' is IMPORTANT! It keeps the permissions
|
|
correct. YOU WERE LOGGED IN AS THE USER SYSOP WEREN'T YOU?????
|
|
<P>Remember to recompile the C client (cd /spider/src; make)
|
|
<P>
|
|
<P>At this point the files have been upgraded. You can (usually) restart the cluster
|
|
in your own time. However, if you attempt to use any new commands or features
|
|
expect it to be fatal! At least your cluster will have been restarted then so it
|
|
will be too late to worry about it!
|
|
<P>
|
|
<P>Now the magic part! From now on when you want to update, simply connect to the
|
|
Internet and then, as the user <EM>sysop</EM> ...
|
|
<P>
|
|
<BLOCKQUOTE><CODE>
|
|
<PRE>
|
|
cd /spider
|
|
cvs -z3 update -d
|
|
</PRE>
|
|
</CODE></BLOCKQUOTE>
|
|
<P>and your files will be updated. As above, remember to recompile the "C" client
|
|
if it has been updated (CVS will tell you) and restart if any of the perl scripts
|
|
have been altered or added, again, CVS will tell you.
|
|
<P>
|
|
<P>You will find any changes documented in the /spider/Changes file.
