35: Anonymous CVS is a method of keeping your local copy of the OpenBSD source
36: tree up to date with respect to changes made to current OpenBSD sources.
1.99 ericj 37: </p>
38:
1.14 downsj 39: <p>
1.15 grr 40: The major advantage of Anonymous CVS over other source code update
41: techniques is that it works directly against a central source code
42: repository or mirror. This means that you have the full set of CVS
43: commands available to control merging and updating your changes with
44: other source changes and for performing diff's, change histories
45: and other queries against the central repository.
1.99 ericj 46: </p>

1.36 deraadt 48: <p>
1.99 ericj 49: The OpenBSD Project currently has three main source repositories:
50: </p>
51:
52: <ul>
53: <li><b>src</b> - Houses all source code for the OpenBSD Operating System.
54: <li><b>ports</b> - Houses the <a href="./ports.html">OpenBSD Ports</a>.
55: <li><b>www</b> - Houses all OpenBSD web pages. (Including this one).
56: </ul>

! 59: To summarize, the real strength of using Anonymous CVS is that it is
! 60: a "tolerant" source code control system - it <strong>respects</strong>
! 61: changes that you have made to your local sources and makes <strong>
! 62: "best efforts"</strong> to update your entire source tree, rather than
! 63: leaving you a list of arcane problems that have to be resolved before
! 64: continuing.

71: <a href=why-cvs.html>
72: CVS is the source code control system used to manage the OpenBSD source tree.</a>
1.16 deraadt 73: It implements a central repository for all officially released source code
1.15 grr 74: and changes, while permitting developers to maintain local copies of the
1.99 ericj 75: source code with their working changes. Developers with "<b>write access</b>"
1.15 grr 76: can commit changes directly to the OpenBSD source tree, while "Anonymous
1.99 ericj 77: CVS" users have "<b>read access</b>" and can keep their local copies of the source
1.15 grr 78: up to date and issue queries against the central depository.
1.99 ericj 79: </p>
80:
1.15 grr 81: <p>
1.22 niklas 82: The major strength of CVS is that it has the ability to perform intelligent
1.15 grr 83: merges of changes to the central repository with changes that you make to
84: your local copy. This means that if you make a change to a module and
85: perform an update, your changes are not "blown away", rather CVS makes
86: best efforts to merge the changes made to the central sources with changes
87: you've made to your local copy.
1.99 ericj 88: </p>
89:
1.15 grr 90: <p>
91: In the event that the changes can't be completely merged, CVS provides a
92: "soft fallback", in terms of providing you with annotated changes to your
1.39 todd 93: local copy, preserving an unmodified copy of your version and continuing
1.15 grr 94: to update any other source modules you requested.

! 101: The latest version of CVS is available at
! 102: <a href=http://download.cyclic.com/pub/>Cyclic</a>.

1.99 ericj 108: People who own an OpenBSD CD may have seen the <i>CVS/</i> dirs on it.
109: Actually there is a reason, the CD has a checkout of the OpenBSD <b>src</b> module
1.95 millert 110: usable to continue updating from. Using this tree will result in a much
1.23 mickey 111: faster initial CVS update than a fresh checkout of the full OpenBSD
112: source tree. There are two ways of using the CD:
1.99 ericj 113: </p>
114:
1.23 mickey 115: <ul>
1.99 ericj 116: <li>To copy the CVS tree from the CD to <i>/usr/src</i> (assuming the CD is mounted on /mnt):
1.22 niklas 117: <pre>
1.99 ericj 118: # <b>cd /mnt; pax -rw CVS Makefile [a-z]* /usr/src</b>
1.22 niklas 119: </pre>
1.99 ericj 120: <li>Use a union mount with the CD below a writable directory. (This can be used when only compiling from the tree.)
1.22 niklas 121: <pre>
1.99 ericj 122: # <b>mount -t union -o -b /mnt /usr/src</b>
1.22 niklas 123: </pre>
1.23 mickey 124: </ul>
1.100 ! ericj 125:
! 126: <p>
! 127: For people who don't have a CD on hand, you can use <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cvs&sektion=1&format=html">cvs(1)</a> to "<b>checkout</b>" the source repository for you. This is discussed in the <a href="#using">next section</a>.
! 128: </p>
! 129:
! 130: <p>
1.99 ericj 131: After this, <i>/usr/src</i> will be a nice checkout area where all <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cvs&sektion=1&format=html">cvs(1)</a> commands will work OK.

! 135: <h3><font color=#0000e0>Using CVS(1) to get and update your source tree.</font></h3>
! 136:
! 137: <p>
! 138: CVS was designed to be a simple way to retrive and update your sources, therefore there
! 139: isn't much involved at all in doing so. To start off you must know which Anonymous CVS server you are going to use. A list of these servers is <a href="#CVSROOT">below</a>.
! 140: Do, however, notice that there are only 3 ways to access these servers.
! 141: </p>
1.99 ericj 142:
1.100 ! ericj 143: <ul>
! 144: <li><b>ssh</b> - Secure Shell can be used to access the anonymous CVS servers. This is the <b>recommended</b> way of doing so, as it is encrypted. As of 2.6 OpenBSD has included OpenSSH in its standard distribution.
! 145: <li><b>rsh</b> - Remote Shell can be used on some of the servers for users who don't have access to <a href="http://www.openssh.com">ssh</a>
! 146: <li><b>pserver</b> - pserver is primarily useful for users who are behind firewalls that block the other two connections.
! 147: </ul>
! 148:
! 149: <p>
! 150: <b>NOTE:</b> - For users wishing to use ssh, you must first set the <i>CVS_RSH</i> variable to ssh.
! 151:
! 152: <ul>
! 153: <li> For Korn/Bourne shells.
! 154: <pre>
! 155: $ <b>export CVS_RSH="/usr/bin/ssh"</b>
! 156: </pre>
! 157: <li> For CSH based shells.
! 158: <pre>
! 159: $ <b>setenv CVS_RSH /usr/bin/ssh</b>
! 160: </pre>
! 161: </ul>
! 162:
! 163: <p>
! 164: Once you have chosen which <a href="#CVSROOT">Anonymous CVS Server</a> you will use, and which method you will use, you can start using cvs. For those of you who have CD's you can start with the CVS checkout that is on the CD by using the method <a href="#starting">above</a> to get the sources onto your system. If you don't have a CD handy, use the method below to checkout the sources. This method puts the OpenBSD source tree into <i>/usr/src</i>.
! 165: </p>
! 166:
! 167: <p>
! 168: <ul><pre>
! 169: # <b>cd /usr; cvs checkout src</b>
! 170: </ul></pre>

1.100 ! ericj 174: The above will checkout the most current sources. Many of you will only want the release sources, especially if you are patching your system. To checkout release sources you must specify a tag along with your command. Example:

382: <p>
383: <li>The OpenBSD project is looking for more anoncvs servers -- read
384: on to find out how you can help.
385: </ul>
386:
387: <p>
388: A sample use of an anoncvs CVS server would be:
1.27 todd 389: <ul>
1.1 deraadt 390: <pre>
1.59 beck 391: % setenv CVSROOT anoncvs@anoncvs.ca.openbsd.org:/cvs
1.1 deraadt 392: % cd /tmp
393: % cvs get src/sys/arch/sparc
1.12 grr 394: [copies the files from the repository to your machine]
1.1 deraadt 395: % cvs log src/sys/arch/sparc/sparc/locore.s
1.12 grr 396: [shows the commit log for the chosen file ]
1.1 deraadt 397: % cvs diff -bc -r1.1 -r1.5 src/sys/arch/sparc/sparc/locore.s
1.12 grr 398: [shows the changes between revisions 1.1 and rev 1.5]
1.1 deraadt 399: </pre>
1.27 todd 400: </ul>
1.1 deraadt 401:
402: <p>
1.18 todd 403: <a name=pserver>In order to use a cvs ``pserver'' (a direct tcp connection instead of using ssh or rsh) you must login once:</a>
404: <pre>
405: [ *NOTE* You must be using cvs version 1.8 or higher to do this ]
1.59 beck 406: % setenv CVSROOT :pserver:anoncvs@anoncvs.ca.openbsd.org:/cvs
1.18 todd 407: % cvs login
1.59 beck 408: (Logging in to anoncvs@anoncvs1.ca.openbsd.org)
1.71 millert 409: CVS password: anoncvs
1.18 todd 410: [this writes a line to ~/.cvspass (filename over-ridden by CVS_PASSFILE).]
411: [An example line from my ~/.cvspass after typing 'blah' for the above ]
412: [password is: ]
413: [:pserver:anoncvs@anoncvs5.usa.openbsd.org:/cvs Au'yc ]
414: [...after logging in ONCE every other use of the above CVSROOT will work ]
415: % cvs -z9 get ksrc-i386 ksrc-common
416: [allows you to retrieve ONLY that necessary to rebuild an i386 kernel ]
417: [ -z9 allows gzip -9 compression, GOOD medicine for slow links ]
418: </pre>
419:
420: <p>
1.39 todd 421: Here is how someone using anoncvs regularly would update his
1.1 deraadt 422: source tree:
1.60 millert 423: <ul><li>First, start out by `get'-ing an initial tree:
1.27 todd 424:
1.1 deraadt 425: <pre>
1.59 beck 426: # setenv CVSROOT anoncvs@anoncvs.ca.openbsd.org:/cvs
1.1 deraadt 427: # cd /usr
428: # cvs -q get -PA src
429: </pre>
1.27 todd 430: </li>
1.37 todd 431:
1.27 todd 432: <li> Anytime afterwards, to `update' this tree:
1.1 deraadt 433: <pre>
1.41 deraadt 434: # cd /usr/src
435: # cvs -q up -PAd
1.1 deraadt 436: </pre>
1.27 todd 437:
1.39 todd 438: Everytime you ran this it would synchronize your /usr/src tree. It would
1.1 deraadt 439: not destroy any of your local changes, rather it would attempt to merge
440: changes in. If you use obj directories (not obj symbolic links) you may
441: wish to append "-I obj" to the cvs command line, this will keep cvs from
442: spitting out a warning about all the obj directories it is going to
443: encounter which are not in the repository.
1.72 millert 444:
445: <p>
446: <li> NOTE: if you are updating a source tree that you initially fetched
447: from a different server, or from a CD, you <strong>must</strong>
448: add the <em>-d $CVSROOT</em> options to cvs. You must also set the
449: <em>CVS_IGNORE_REMOTE_ROOT</em> environment variable.
450:
451: <pre>
452: # cd /usr/src
453: # cvs -d $CVSROOT -q up -PAd
454: </pre>
455:
1.27 todd 456: </li>
457: </ul>
458:
1.37 todd 459: <p>
460: To <a name=ports>use</a> <a href=ports.html>ports</a>, it is similar to src:
461: <ul><li>
462: <pre>
1.59 beck 463: # setenv CVSROOT anoncvs@anoncvs.ca.openbsd.org:/cvs
1.37 todd 464: # cd /usr
465: # cvs -q get -PA ports
1.38 deraadt 466: </pre>
1.37 todd 467: </li>
468: <li> Anytime afterwards, to `update' this tree:
469: <pre>
470: # cd /usr
471: # cvs -q up -PAd ports
472: </pre>
473: </li>
474: </p>
475: </ul>
476:
1.27 todd 477: In the above example, '-q' is optional, only intended to minimize
478: cvs's output. For those who like to see screenfulls of output, it
479: can be omitted.
1.1 deraadt 480:
481: <p>
1.12 grr 482: or to make a diff of a locally patched module (here cd.c) to include with
483: a bug report:
484: <pre>
485: # cd /usr
486: # cvs diff -u src/sys/scsi/cd.c > /tmp/patch
487: </pre>
1.37 todd 488: </p>
1.12 grr 489:
490: <p>
1.1 deraadt 491: The CVS man page (included with the CVS sources) has much more
492: information about how CVS can be used.
493:
494: <p>
1.12 grr 495: <strong>Warning:</strong>
496: When using cvs you should take care that your current directory is either
497: the root of the tree you're referencing or in a separate place such as /tmp.
498: Some commands such as "get" can create an arbitrary sub-tree in the current
499: directory, and a subsequent update will recursively flesh out this sub-tree.
500:
501: <p>
1.1 deraadt 502: The anoncvs service gives fledgling developers a chance to learn CVS
503: operation and get thoroughly involved in the development process
504: before getting "commit" access -- as a result of showing useful
505: skills and high quality results they will naturally later be given
506: developer access. As well, people providing patches can create
507: their "diff"s relative to the CVS tree, which will ease integration.
508:
509: <p>
1.15 grr 510: <strong>Anoncvs: rsh vs. ssh</strong>
1.12 grr 511: <br>
512: By default, the CVS client uses rsh to talk to the CVS server. Many
1.39 todd 513: of the CVS sites no longer support rsh for security reasons or a local
1.12 grr 514: problem like a firewall or imperfect protocol emulator such as slirp
515: may prevent you from using rsh.
1.97 deraadt 516: The alternative is a to use a "secure shell" connection using either
517: <a href=http://www.openssh.com>OpenSSH (*FREE*)</a> or
518: <a href=http://www.cs.hut.fi/ssh/>ssh (non-commercial and commercial)</a>.
1.68 wvdputte 519:
520: <p>
1.97 deraadt 521: The OpenBSD anoncvs repositries support the SSH1 protocol, not the SSH2
522: protocol due to the use of a "strict non-commercial use licensing policy".
1.28 beck 523:
1.75 millert 524: <p>
525: Once ssh is installed, one sets the environment variable
1.28 beck 526: <strong>CVS_RSH</strong> to point to ssh (typically
527: <strong>/usr/local/bin/ssh</strong>). If your local site prevents you
528: from connecting out to port 22 (which ssh defaults to using) use port
529: 2022.
1.1 deraadt 530:
531: <p>
532: Do not be tempted to turn on compression since CVS already compresses.
533: Use something like the following in your <strong>$HOME/.ssh/config</strong>
1.10 millert 534: file. Note that not all anoncvs servers allow ssh connections on
1.21 millert 535: port 2022. Also note that most anoncvs servers no longer accept
536: the <strong>none</strong> cipher as it is disabled in recent
537: versions of ssh for security reasons.
1.1 deraadt 538: <pre>
1.59 beck 539: Host anoncvs.ca.openbsd.org
1.1 deraadt 540: Port 2022
541: </pre>
542:
543: <p>
544: CVS is a little noisy starting up; to quiet it a bit you may want to
545: do this:
546: <pre>
547: setenv CVS_CLIENT_PORT -1
548: </pre>
549:
550: <p>
1.8 deraadt 551: If you wish to change from one CVS server to another (say your normal one is
552: down, or for any other reason), the environment variable which will let you
553: do this is
554: <pre>
555: setenv CVS_IGNORE_REMOTE_ROOT
556: </pre>
1.72 millert 557: Note that you will also need to use the <strong>-d</strong> flag
558: as mentioned above.
1.8 deraadt 559:
1.65 matthieu 560: <p><strong>X11 Source tree</strong>
561: <br>
562: Anoncvs mirrors also carry the OpenBSD X11 source tree. You can adapt
563: the recipe above to update your X11 source tree from the second CD.
564: Either copy or use a union mount to get the X11 sources in /usr/X11:
565: <ul>
566: <li>copy the tree off it (assuming the 2nd CD is mounted on /mnt):
567: <pre>
568: <b>#</b> cd /mnt; cp -Rp X11 /usr
569: </pre>
570: <li>use a union mount with the CD below a writable directory.
571: <pre>
572: <b>#</b> mount -t union -o -b /mnt/X11 /usr/X11
573: </pre>
574: </ul>
575: After this, /usr/X11 will be ready to be used by cvs. You can for
576: example update it to -current source (assuming you've already set
577: the <b>CVSROOT</b> environment variable):
578: <pre>
579: <b>#</b> cd /usr/X11
580: <b>#</b> cvs -q update -PAd
581: </pre>
582:
583: <p><strong>Setting up a new anoncvs mirror</strong>
584: <br>
1.1 deraadt 585: If you wish to be a new anoncvs mirror site, please contact the anoncvs
586: <a href=mailto:deraadt@theos.com>maintainer</a>.
1.30 beck 587: Anoncvs mirrors require about 500MB of disk, and use up to 4MB of swap
1.1 deraadt 588: per anoncvs user (assuming the user does a large operation; while smaller
589: operations use fewer resources, anoncvs still makes much more of an
590: impact than ftp or sup). Such anoncvs machines should have excellent
591: network connectivity for the area they are expected to serve. A
592: <a href=anoncvs.shar>document</a>
593: which describes the setup of anoncvs servers is available.
594:
1.60 millert 595: <h3><font color=#0000e0>Final notes:</font></h3>
596: After upgrading your source tree, you should read the comments
597: at the top of <KBD>/usr/src/Makefile</KBD> before attemping
598: a build. Also, you should build a new kernel <strong>before</strong>
599: doing a <KBD>make build</KBD> if possible. In some cases it make be
600: necessary to rebuild and install the <KBD>config</KBD> utility before
601: you can build the kernel. If <KBD>config GENERIC</KBD> fails this
602: is probably the case.
603: <p>
604: It is important to note that upgrading from a release to the current tree
605: by rebuilding the sources can be rather difficult due to dependencies
606: that are often not obvious. Therefore, it is suggested that you first
607: install the latest snapshot before attemping a tree build from source.
