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. +Either way you will want to change directory to a new place, if you want to +update an existing installation then I suggest /tmp, otherwise choose a +suitable place according to the normal installation instructions. +
+
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) restrt 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. +
