1.99 ericj 38:
1.15 grr 39: <p>
40: Anonymous CVS is a method of keeping your local copy of the OpenBSD source
41: tree up to date with respect to changes made to current OpenBSD sources.
1.109 jason 42: In addition to following the bleeding edge of development, it is
43: also possible to track the patches for errata of a release.
1.99 ericj 44: </p>
45:
1.14 downsj 46: <p>
1.15 grr 47: The major advantage of Anonymous CVS over other source code update
48: techniques is that it works directly against a central source code
49: repository or mirror. This means that you have the full set of CVS
50: commands available to control merging and updating your changes with
51: other source changes and for performing diff's, change histories
52: and other queries against the central repository.
1.99 ericj 53: </p>
54:
1.36 deraadt 55: <p>
1.99 ericj 56: The OpenBSD Project currently has three main source repositories:
57: </p>
58:
59: <ul>
60: <li><b>src</b> - Houses all source code for the OpenBSD Operating System.
61: <li><b>ports</b> - Houses the <a href="./ports.html">OpenBSD Ports</a>.
62: <li><b>www</b> - Houses all OpenBSD web pages. (Including this one).
63: </ul>
64:
1.100 ericj 65: <p>
66: To summarize, the real strength of using Anonymous CVS is that it is
67: a "tolerant" source code control system - it <strong>respects</strong>
68: changes that you have made to your local sources and makes <strong>
69: "best efforts"</strong> to update your entire source tree, rather than
70: leaving you a list of arcane problems that have to be resolved before
71: continuing.

75: <h3><font color=#0000e0>What is CVS?</font></h3>
1.99 ericj 76:
1.36 deraadt 77: <p>
78: <a href=why-cvs.html>
79: CVS is the source code control system used to manage the OpenBSD source tree.</a>
1.16 deraadt 80: It implements a central repository for all officially released source code
1.15 grr 81: and changes, while permitting developers to maintain local copies of the
1.99 ericj 82: source code with their working changes. Developers with "<b>write access</b>"
1.15 grr 83: can commit changes directly to the OpenBSD source tree, while "Anonymous
1.99 ericj 84: CVS" users have "<b>read access</b>" and can keep their local copies of the source
1.15 grr 85: up to date and issue queries against the central depository.
1.99 ericj 86: </p>
87:
1.15 grr 88: <p>
1.22 niklas 89: The major strength of CVS is that it has the ability to perform intelligent
1.15 grr 90: merges of changes to the central repository with changes that you make to
91: your local copy. This means that if you make a change to a module and
92: perform an update, your changes are not "blown away", rather CVS makes
93: best efforts to merge the changes made to the central sources with changes
94: you've made to your local copy.
1.99 ericj 95: </p>
96:
1.15 grr 97: <p>
98: In the event that the changes can't be completely merged, CVS provides a
99: "soft fallback", in terms of providing you with annotated changes to your
1.39 todd 100: local copy, preserving an unmodified copy of your version and continuing
1.15 grr 101: to update any other source modules you requested.

107: <p>
108: The latest version of CVS is available at
1.111 deraadt 109: <a href=http://www.cyclic.com/CVS/Dev/code/>Cyclic</a>.
1.100 ericj 110: Versions earlier than 1.6 are not recommended, and may not work.
111: If you already have OpenBSD installed, CVS is included.

1.22 niklas 114: <p>
1.99 ericj 115: People who own an OpenBSD CD may have seen the <i>CVS/</i> dirs on it.
116: Actually there is a reason, the CD has a checkout of the OpenBSD <b>src</b> module
1.95 millert 117: usable to continue updating from. Using this tree will result in a much
1.23 mickey 118: faster initial CVS update than a fresh checkout of the full OpenBSD
119: source tree. There are two ways of using the CD:
1.99 ericj 120: </p>
121:
1.23 mickey 122: <ul>
1.99 ericj 123: <li>To copy the CVS tree from the CD to <i>/usr/src</i> (assuming the CD is mounted on /mnt):
1.22 niklas 124: <pre>
1.99 ericj 125: # <b>cd /mnt; pax -rw CVS Makefile [a-z]* /usr/src</b>
1.22 niklas 126: </pre>
1.110 wvdputte 127: <li>Use a union mount (see <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=mount_union&apropos=0&sektion=8&manpath=OpenBSD+Current&format=html">mount_union(8)</a>) with the CD below a writable directory. (This can be used when only compiling from the tree.)
1.22 niklas 128: <pre>
1.99 ericj 129: # <b>mount -t union -o -b /mnt /usr/src</b>
1.22 niklas 130: </pre>
1.23 mickey 131: </ul>
1.100 ericj 132:
133: <p>
134: 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>.
135: </p>
136:
137: <p>
1.99 ericj 138: 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.

142: <h3><font color=#0000e0>Using CVS(1) to get and update your source tree.</font></h3>
143:
144: <p>
1.109 jason 145: CVS was designed to be a simple way to retrieve and update your sources,
146: therefore there isn't much involved at all in doing so. You must first
147: decide whether you want to track <i>current</i> or a patch branch.
1.112 kjell 148: The current tree has all of the up to the minute changes,
1.109 jason 149: whereas a patch branch contains a formal release plus the patches
150: from the <a href="errata.html">errata</a> already applied.
151:
152: <p>Once you have decided which tree to follow, you much choose which Anonymous
153: CVS server you are going to use. A list of these servers is
154: <a href="#CVSROOT">below</a>. Do, however, notice that there are 3 ways
155: to access these servers.
1.100 ericj 156: </p>
1.99 ericj 157:
1.100 ericj 158: <ul>
159: <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.
160: <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>
161: <li><b>pserver</b> - pserver is primarily useful for users who are behind firewalls that block the other two connections.
162: </ul>
163:
164: <p>
165: <b>NOTE:</b> - For users wishing to use ssh, you must first set the <i>CVS_RSH</i> variable to ssh.
166:
167: <ul>
168: <li> For Korn/Bourne shells.
169: <pre>
170: $ <b>export CVS_RSH="/usr/bin/ssh"</b>
171: </pre>
172: <li> For CSH based shells.
173: <pre>
174: $ <b>setenv CVS_RSH /usr/bin/ssh</b>
175: </pre>
176: </ul>
177:
178: <p>
179: 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>.
180: </p>
181:
182: <p>
183: <ul><pre>
1.114 marc 184: # <b>cd /usr; cvs checkout -P src</b>
1.100 ericj 185: </ul></pre>
186: </p>
1.99 ericj 187:
1.1 deraadt 188: <p>
1.109 jason 189: The above will checkout the <i>current</i> source tree. Many of you will
190: only want a patch branch sources. To checkout a patch branch, you must
191: specify a tag along with your command. Example:
1.100 ericj 192: </p>
1.1 deraadt 193:
194: <p>
1.100 ericj 195: <ul><pre>
1.109 jason 196: # <b>cd /usr; cvs checkout -P -rOPENBSD_2_7 src</b>
1.100 ericj 197: </ul></pre>
1.109 jason 198: Or OPENBSD_2_6 for 2.6, etc.
1.100 ericj 199: </p>
200:
1.109 jason 201: <p> Currently only the OPENBSD_2_7 tag contains the release sources and
202: errata already applied.

208: There are two levels of source tree access:
209:
210: <dl>
211: <dt><strong>Read-write access for developers:</strong>
212: <dd>Developers who need to commit changes to the source tree must have
213: an account on the OpenBSD machines. Getting this access will be a
214: natural result of working on the sources with other OpenBSD developers.
215: If someone does some good work and shows they can work with the team,
216: they will get an account.

1.104 ericj 479: </pre></ul>
1.18 todd 480:
481: <p>
1.39 todd 482: Here is how someone using anoncvs regularly would update his
1.1 deraadt 483: source tree:
1.60 millert 484: <ul><li>First, start out by `get'-ing an initial tree:
1.27 todd 485:
1.109 jason 486: <p> (If you are following <i>current</i>):
1.104 ericj 487: <ul><pre>
488: # <strong>setenv CVSROOT anoncvs@anoncvs.ca.openbsd.org:/cvs</strong>
489: # <strong>cd /usr</strong>
490: # <strong>cvs -q get -PA src</strong>
491: </pre></ul>
1.109 jason 492:
493: <p> (If you are following the patch branch for 2.7):
494: <ul><pre>
495: # <strong>setenv CVSROOT anoncvs@anoncvs.ca.openbsd.org:/cvs</strong>
496: # <strong>cd /usr</strong>
497: # <strong>cvs -q get -rOPENBSD_2_7 -P src</strong>
498: </pre></ul>
1.27 todd 499: </li>
1.37 todd 500:
1.27 todd 501: <li> Anytime afterwards, to `update' this tree:
1.109 jason 502: <p> (If you are following <i>current</i>):
1.104 ericj 503: <ul><pre>
504: # <strong>cd /usr/src</strong>
505: # <strong>cvs -q up -PAd</strong>
506: </pre></ul>
1.27 todd 507:
1.109 jason 508: <p> (If you are following the patch branch for 2.7):
509: <ul><pre>
510: # <strong>cd /usr/src</strong>
511: # <strong>cvs -q up -rOPENBSD_2_7 -Pd</strong>
512: </pre></ul>
513:
1.39 todd 514: Everytime you ran this it would synchronize your /usr/src tree. It would
1.1 deraadt 515: not destroy any of your local changes, rather it would attempt to merge
516: changes in. If you use obj directories (not obj symbolic links) you may
517: wish to append "-I obj" to the cvs command line, this will keep cvs from
518: spitting out a warning about all the obj directories it is going to
519: encounter which are not in the repository.
1.72 millert 520:
521: <p>
1.109 jason 522: <li> NOTES: if you are updating a source tree that you initially fetched
1.72 millert 523: from a different server, or from a CD, you <strong>must</strong>
524: add the <em>-d $CVSROOT</em> options to cvs. You must also set the
1.109 jason 525: <em>CVS_IGNORE_REMOTE_ROOT</em> environment variable. If you are following
526: a patch branch, be sure to always <strong>omit</strong> the <code>-A</code>
527: flag to cvs, or you may find yourself tracking <i>current</i> instead.
1.72 millert 528:
1.109 jason 529: <p> (If you are following <i>current</i>):
1.104 ericj 530: <ul><pre>
531: # <strong>cd /usr/src</strong>
532: # <strong>cvs -d $CVSROOT -q up -PAd</strong>
533: </pre></ul>
1.72 millert 534:
1.109 jason 535: <p> (If you are following a patch branch):
536: <ul><pre>
537: # <strong>cd /usr/src</strong>
538: # <strong>cvs -d $CVSROOT -q up -Pd</strong>
539: </pre></ul>

543:
1.37 todd 544: <p>
545: To <a name=ports>use</a> <a href=ports.html>ports</a>, it is similar to src:
546: <ul><li>
547: <pre>
1.104 ericj 548: # <strong>setenv CVSROOT anoncvs@anoncvs.ca.openbsd.org:/cvs</strong>
549: # <strong>cd /usr</strong>
550: # <strong>cvs -q get -PA ports</strong>
1.38 deraadt 551: </pre>
1.37 todd 552: </li>
553: <li> Anytime afterwards, to `update' this tree:

1.104 ericj 555: # <strong>cd /usr</strong>
556: # <strong>cvs -q up -PAd ports</strong>
1.37 todd 557: </pre>
558: </li>
559: </p>
560: </ul>
561:
1.104 ericj 562: In the above example, <i>-q</i> is optional, only intended to minimize
1.27 todd 563: cvs's output. For those who like to see screenfulls of output, it
564: can be omitted.
1.1 deraadt 565:

1.1 deraadt 578: information about how CVS can be used.
579:
580: <p>
1.105 ericj 581: <strong>X11 Source tree</strong>
582: <br>
583: Anoncvs mirrors also carry the OpenBSD X11 source tree. You can adapt
584: the recipe above to update your X11 source tree from the second CD.
585: Either copy or use a union mount to get the X11 sources in <i>/usr/X11</i>:
586:
587: <ul>
588: <li>copy the tree off it (assuming the 2nd CD is mounted on /mnt):
589: <pre>
590: # <strong>cd /mnt; cp -Rp X11 /usr</strong>
591: </pre>
592: <li>use a union mount with the CD below a writable directory.
593: <pre>
594: # <strong>mount -t union -o -b /mnt/X11 /usr/X11</strong>
595: </pre></ul>
596:
597: After this, <i>/usr/X11</i> will be ready to be used by cvs. You can for
598: example update it to -current source (assuming you've already set
599: the <b>CVSROOT</b> environment variable):
600:
601: <ul><pre>
602: # <strong>cd /usr/X11</strong>
603: # <strong>cvs -q update -PAd</strong>
604: </pre></ul>
605:
606: <p>
1.12 grr 607: <strong>Warning:</strong>
608: When using cvs you should take care that your current directory is either
1.109 jason 609: the root of the tree you are referencing or in a separate place such as /tmp.
1.12 grr 610: Some commands such as "get" can create an arbitrary sub-tree in the current
611: directory, and a subsequent update will recursively flesh out this sub-tree.
612:
613: <p>
1.1 deraadt 614: The anoncvs service gives fledgling developers a chance to learn CVS
615: operation and get thoroughly involved in the development process
616: before getting "commit" access -- as a result of showing useful
617: skills and high quality results they will naturally later be given
618: developer access. As well, people providing patches can create
619: their "diff"s relative to the CVS tree, which will ease integration.

623: <h3><font color=#0000e0>Use rsh(1) or ssh(1)?</font></h3>
624:
1.1 deraadt 625: <p>
1.15 grr 626: <strong>Anoncvs: rsh vs. ssh</strong>
1.12 grr 627: <br>
628: By default, the CVS client uses rsh to talk to the CVS server. Many
1.39 todd 629: of the CVS sites no longer support rsh for security reasons or a local
1.12 grr 630: problem like a firewall or imperfect protocol emulator such as slirp
631: may prevent you from using rsh.
1.97 deraadt 632: The alternative is a to use a "secure shell" connection using either
633: <a href=http://www.openssh.com>OpenSSH (*FREE*)</a> or
634: <a href=http://www.cs.hut.fi/ssh/>ssh (non-commercial and commercial)</a>.
1.68 wvdputte 635:
636: <p>
1.97 deraadt 637: The OpenBSD anoncvs repositries support the SSH1 protocol, not the SSH2
638: protocol due to the use of a "strict non-commercial use licensing policy".
1.28 beck 639:
1.75 millert 640: <p>
641: Once ssh is installed, one sets the environment variable
1.28 beck 642: <strong>CVS_RSH</strong> to point to ssh (typically
1.113 brad 643: <strong>/usr/bin/ssh</strong>). If your local site prevents you
1.28 beck 644: from connecting out to port 22 (which ssh defaults to using) use port
645: 2022.
1.1 deraadt 646:
647: <p>
648: Do not be tempted to turn on compression since CVS already compresses.
649: Use something like the following in your <strong>$HOME/.ssh/config</strong>
1.10 millert 650: file. Note that not all anoncvs servers allow ssh connections on
1.21 millert 651: port 2022. Also note that most anoncvs servers no longer accept
652: the <strong>none</strong> cipher as it is disabled in recent
653: versions of ssh for security reasons.

681:
682: <p>
683: Users wishing to mirror the OpenBSD CVS tree itself may now do so
684: from <em>anoncvs.usa.openbsd.org</em>. Note that this is the cvs
685: tree, <b>not</b> a checked out source tree. It is only useful if
686: you want to be able to do fast cvs operations (diff, annotate, etc)
687: or if you have multiple source trees and you only want to transfer
688: new data once (you can then checkout a tree from your local cvs
689: mirror).
690: <p>
691: A sample supfile would be:
692: <pre>
693: cvs host=anoncvs.usa.openbsd.org hostbase=/ base=/home delete
694: </pre>
695: <p>
696: which would mirror the cvs tree into /home/cvs with the sup data
697: files ending up in /home/sup. The full OpenBSD cvs tree is just
698: under a gigabyte in size.

1.107 millert 706: Anoncvs mirrors require about 1GB of disk, and use up to 4MB of swap
1.1 deraadt 707: per anoncvs user (assuming the user does a large operation; while smaller

1.60 millert 714: <h3><font color=#0000e0>Final notes:</font></h3>
715: After upgrading your source tree, you should read the comments

720: you can build the kernel. If <KBD>config GENERIC</KBD> fails this
721: is probably the case.
722: <p>
723: It is important to note that upgrading from a release to the current tree
724: by rebuilding the sources can be rather difficult due to dependencies
725: that are often not obvious. Therefore, it is suggested that you first
