Updated 16-Mar-1995.</em> - - <tt/CTM/ is a method for keeping a remote directory tree in sync with a - central one. It has been developed for usage with FreeBSD's source - trees, though other people may find it useful for other purposes as - time goes by. Little, if any, documentation currently exists at - this time on the process of creating deltas, so talk to &a.phk; - for more information should you wish to use <tt/CTM/ for other things. - - <sect2><heading>Why should I use <tt/CTM/?</heading> - <p><tt/CTM/ will give you a local copy of the ``FreeBSD-current'' - sources. If you are an active developer on FreeBSD, but have lousy - or non-existent TCP/IP connectivity, <tt/CTM/ was made for you. - You will need to transfer up to four deltas per day (or you can - have them arrive in email automatically), the sizes for which are - always kept as small as possible. This is typically less than 5K, - with the occasional (one in ten) being 10-50K and every now and - then a biggie of 100K+ or more coming around. - - You will also need to make yourself aware of the various caveats in - running ``current'' sources, and for this it is recommended that - you read <ref id="current" name="Staying current with FreeBSD">. - - <sect2><heading>What do I need to use <tt/CTM/?</heading> - - <p>You will need two things: The ``<tt/CTM/'' program and the initial - deltas to feed it (to get up to ``current'' levels). - - The <tt/CTM/ program has been part of FreeBSD ever since version 2.0 - was released, and lives in <tt>/usr/src/usr.sbin/<tt/CTM/</tt> if you - have a copy of the source online. - - If you are running a pre-2.0 version of FreeBSD, you can fetch the - current <tt/CTM/ sources directly from: - - <url - url="ftp://ftp.FreeBSD.ORG/pub/FreeBSD/FreeBSD-current/src/usr.sbin/ctm"> - - The ``deltas'' you feed <tt/CTM/ can be had two ways, FTP or e-mail. - If you have general FTP access to the Internet then the following - FTP sites support access to <tt/CTM/: - - <url url="ftp://ftp.FreeBSD.ORG/pub/FreeBSD/CTM"> - - or see section <ref id="mirrors-ctm" name="mirrors">. - - FTP the relevant directory and fetch the <tt/README/ file, - starting from there. - - If you only have access to electronic mail or are otherwise blocked - from using FTP then you may wish to get your deltas via email: - - Send email to &a.majordomo to subscribe to - the list ``ctm-src-cur''. (If you do not know how to subscribe - yourself using majordomo, send a message first containing the - word ``help'' - it will send you back usage instructions.) - - When you begin receiving your <tt/CTM/ updates in the mail, you may - use the <tt/ctm_rmail/ program to unpack and apply them. You - can actually use the <tt/ctm_rmail/ program directly from a entry - in <tt>/etc/aliases</tt> if you want to have the process run in a - fully automated fashion. Check the <tt/ctm_rmail/ man page for more - details. - - <bf/NOTE/: No matter what method you use to get the <tt/CTM/ - deltas, you should subscribe to the <tt/ctm-announce@FreeBSD.ORG/ - mailing list. In the future, this will be the only place where - announcements concerning the operations of the <tt/CTM/ system will be - posted. Send an email to &a.majordomo with a single - line of ``<tt/subscribe ctm-announce/'' to get added to the list. - - <sect2><heading>Starting off with <tt/CTM/ for the first time</heading> - <p>Before you can start using <tt/CTM/ deltas, you will need to get a - special ``base'' delta that provides the starting point for all - deltas produced subsequently to it. - - You can recognize a base delta by the ``<tt/A/'' appended to the - number (<tt/src-cur.0341A.gz/ for instance). As a rule a base - delta is produced every 100 deltas, the next one will be - <tt/src-cur.0400A.gz/. By the way, they are large! 25 to 30 - Megabytes of <tt/gzip/'ed data is common for a base delta. - - If you do have the 2.0-RELEASE <tt/srcdist/, you can instead - retrieve the <tt/src-cur.0372R20.gz/ file, it is only 4Mb and it - will take you to current from the 2.0-RELEASE sources. - - Once you've picked a base delta to start from, you will also need - all deltas with higher numbers following it. - - <sect2><heading>Using <tt/CTM/ in your daily life</heading> - <p>To apply the deltas, simply say - <verb> - cd /where/ever/you/want/the/stuff - ctm -v -v /where/you/store/your/deltas/src-cur.* - </verb> - <tt/CTM/ understands deltas which have been put through <tt/gzip/, - so you do not need to gunzip them first, this saves disk space. - - Unless it feels very secure about the entire process, <tt/CTM/ will - not touch your tree. To verify a delta you can also use the - ``<tt/-c/'' flag and <tt/CTM/ will not actually touch your tree; it will - merely verify the integrity of the delta and see if it would apply - cleanly to your current tree. - - There are other options to <tt/CTM/ as well, look in the sources - for more details. - - I would also be very happy if somebody could help with the ``user - interface'' portions, as I have realized that I cannot make up my - mind on what options should do what, how and when... - - That's really all there is to it. Every time you get a new delta, - just run it through <tt/CTM/ to keep your sources up to date. - - Do not remove the deltas if they are hard to download again. You - just might want to keep them around in case something bad happens. - Even if you only have floppy disks, consider using <tt/fdwrite/ to - make a copy. - - - <sect2><heading>Future plans for <tt/CTM/</heading> - <p> - Tons of them: - <itemize> - <item> - Make local modifications to the tree possible. One way to do - it could be this:<p> When <tt/CTM/ wants to edit the file - ``<tt>foo/bar.c</tt>'', it would first check for the existence - of <tt>foo/bar.c#CTM</tt> If this file exists, the delta is - applied to it instead. This way the <tt>foo/bar.c</tt> file - can be edited to suit local needs. - <item> - Make a ``restore file(s)'' option to <tt/CTM/, something like: - <verb> - ctm -r src/sys/i386/wd.c /here/are/my/deltas/src-cur.* - </verb> - would restore <tt/wd.c/ to the current status from the files. - <item> - Clean up the options to <tt/CTM/, they became confusing and - counter intuitive. - </itemize> - - The bad news is that I am very busy, so any help in doing this will - be most welcome. And do not forget to tell me what you want also... - - <sect2><heading>Miscellaneous stuff</heading> - <p> - All the ``DES infected'' (e.g. export controlled) source is not - included. You will get the ``international'' version only. If - sufficient interest appears, we will set up a ``<tt/sec-cur/'' - sequence too. - - If you are a frequent or valuable contributor to FreeBSD, I will be - willing to arrange special services, one option is delivery via - <tt/ftp/ or <tt/rcp/ to a machine closer to you. You need to have - earned this, since it takes time to do, but I will be all the more - happy to do it for you then. - - There is a sequence of deltas for the <tt/ports/ collection too, - but interest has not been all that high yet. Tell me if you want - an email list for that too and we will consider setting it up. - - If you have commit privileges or are similarly authorized by the - FreeBSD core team, you can also get access to the CVS repository - tree by the same means. Contact &a.phk; - for details. - - - <sect2><heading>Thanks!</heading> - <p> - <descrip> - <tag/&a.bde;/ - for his pointed pen and invaluable comments. - <tag/&a.sos;/ - for patience. - <tag/Stephen McKay/ - wrote <tt/ctm_[rs]mail/, much appreciated. - <tag/&a.jkh;/ - for being so stubborn that I had to make it better. - <tag/All the users/ - I hope you like it... - </descrip> - |
