1.15 grr 34: <p>
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>
47:
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>
57:
1.100 ericj 58: <p>
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.

1.99 ericj 69:

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>.
103: Versions earlier than 1.6 are not recommended, and may not work.
104: If you already have OpenBSD installed, CVS is included.

1.22 niklas 107: <p>
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.
1.100 ericj 132: </p>

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>
171: </p>
1.99 ericj 172:
1.1 deraadt 173: <p>
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:
175: </p>
1.1 deraadt 176:
177: <p>
1.100 ericj 178: <ul><pre>
179: # <b>cd /usr; cvs checkout -rOPENBSD_2_6 src</b>
180: </ul></pre>
181: Or OPENBSD_2_5 for 2.5, etc.

1.1 deraadt 187:
188: <p>
189: There are two levels of source tree access:
190:
191: <dl>
192: <dt><strong>Read-write access for developers:</strong>
193: <dd>Developers who need to commit changes to the source tree must have
194: an account on the OpenBSD machines. Getting this access will be a
195: natural result of working on the sources with other OpenBSD developers.
196: If someone does some good work and shows they can work with the team,
197: they will get an account.
198: </dl>
199:
200: <dl>
201: <dt><strong>Read-only access for everyone:</strong>
202: <dd>Anyone can access the read-only CVS repositories. These copies
203: of the read-write CVS repository are mirrored often. To use one,
204: set your <strong>CVSROOT</strong> environment variable to one of

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