CVS stands for "Concurrent Versions System" and the CVS for DXSpider is held at Sourceforge. This means that it is possible to update your DXSpider installation to the latest sources by using a few simple commands.
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!!!
DID I MENTION..... ONLY DO THIS IF YOU ARE WILLING TO ACCEPT THE CONSEQUENCES!!!
I am of course assuming that you have a machine with both DXSpider and Internet access running.
BEFORE YOU EVEN CONSIDER STARTING WITH THIS MAKE A BACKUP OF YOUR ENTIRE SPIDER TREE!!
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 ...
First login as the user sysop. Next you need to connect to the CVS repository. You do this with the command below ...
cvs -d:pserver:anonymous@cvs.DXSpider.sourceforge.net:/cvsroot/dxspider login
You will get a password prompt. Simply hit return here and your machine should return to a normal linux prompt.
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.
If you are installing Spider from CVS then change directory to /home/sysop
If you are wanting to update Spider then cd to /tmp
The next step will create a brand new 'spider' directory in your current directory.
cvs -z3 -d:pserver:anonymous@cvs.DXSpider.sourceforge.net:/cvsroot/dxspider co spider
This command is all on one line.
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.
Now if you are doing a new installation, that's it. Carry on as if you have just downloaded and untarred the lastest tarball.
If you want to upgrade your current installation then do this ...
tar cvfz /tmp/s.tgz spider
cd /
tar xvfzp /tmp/s.tgz
This is assuming you downloaded to the /tmp directory of course.
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?????
Remember to recompile the C client (cd /spider/src; make)
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!
Now the magic part! From now on when you want to update, simply connect to the Internet and then, as the user sysop ...
cd /spider
cvs -z3 update -d
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.
You will find any changes documented in the /spider/Changes file.
