41: Anonymous CVS is a method of keeping your local copy of the OpenBSD source
42: tree up to date with respect to changes made to current OpenBSD sources.
1.109 jason 43: In addition to following the bleeding edge of development, it is
44: also possible to track the patches for errata of a release.
1.99 ericj 45: </p>
46:
1.14 downsj 47: <p>
1.15 grr 48: The major advantage of Anonymous CVS over other source code update
49: techniques is that it works directly against a central source code
50: repository or mirror. This means that you have the full set of CVS
51: commands available to control merging and updating your changes with
52: other source changes and for performing diff's, change histories
53: and other queries against the central repository.
1.99 ericj 54: </p>
55:
1.36 deraadt 56: <p>
1.135 naddy 57: The OpenBSD Project currently has five main source repositories:
1.99 ericj 58: </p>
59:
60: <ul>
1.140 horacio 61: <li><b>src</b> - Houses all source code for the OpenBSD Operating System.</li>
62: <li><b>ports</b> - Houses the <a href="./ports.html">OpenBSD Ports</a>.</li>
63: <li><b>www</b> - Houses all OpenBSD web pages. (Including this one).</li>
1.135 naddy 64: <li><b>X11</b> - Houses OpenBSD's adaptation of the
65: <a href="http://www.XFree86.org/">XFree86-3</a> software project.</li>
66: <li><b>XF4</b> - Houses OpenBSD's adaptation of the

1.100 ericj 70: <p>
71: To summarize, the real strength of using Anonymous CVS is that it is
72: a "tolerant" source code control system - it <strong>respects</strong>
73: changes that you have made to your local sources and makes <strong>
74: "best efforts"</strong> to update your entire source tree, rather than
75: leaving you a list of arcane problems that have to be resolved before
76: continuing.

1.135 naddy 82: <a href="why-cvs.html">
1.36 deraadt 83: CVS is the source code control system used to manage the OpenBSD source tree.</a>
1.16 deraadt 84: It implements a central repository for all officially released source code
1.15 grr 85: and changes, while permitting developers to maintain local copies of the
1.99 ericj 86: source code with their working changes. Developers with "<b>write access</b>"
1.15 grr 87: can commit changes directly to the OpenBSD source tree, while "Anonymous
1.99 ericj 88: CVS" users have "<b>read access</b>" and can keep their local copies of the source
1.15 grr 89: up to date and issue queries against the central depository.
1.99 ericj 90: </p>
91:
1.15 grr 92: <p>
1.22 niklas 93: The major strength of CVS is that it has the ability to perform intelligent
1.15 grr 94: merges of changes to the central repository with changes that you make to
95: your local copy. This means that if you make a change to a module and
96: perform an update, your changes are not "blown away", rather CVS makes
97: best efforts to merge the changes made to the central sources with changes
98: you've made to your local copy.
1.99 ericj 99: </p>
100:
1.15 grr 101: <p>
102: In the event that the changes can't be completely merged, CVS provides a
103: "soft fallback", in terms of providing you with annotated changes to your
1.39 todd 104: local copy, preserving an unmodified copy of your version and continuing
1.15 grr 105: to update any other source modules you requested.

1.100 ericj 109:
110: <p>
111: The latest version of CVS is available at
1.140 horacio 112: <a href="http://www.cvshome.org/">Cyclic</a>.
1.100 ericj 113: Versions earlier than 1.6 are not recommended, and may not work.
114: If you already have OpenBSD installed, CVS is included.

1.22 niklas 117: <p>
1.99 ericj 118: People who own an OpenBSD CD may have seen the <i>CVS/</i> dirs on it.
119: Actually there is a reason, the CD has a checkout of the OpenBSD <b>src</b> module
1.95 millert 120: usable to continue updating from. Using this tree will result in a much
1.23 mickey 121: faster initial CVS update than a fresh checkout of the full OpenBSD
122: source tree. There are two ways of using the CD:
1.99 ericj 123: </p>
124:
1.23 mickey 125: <ul>
1.99 ericj 126: <li>To copy the CVS tree from the CD to <i>/usr/src</i> (assuming the CD is mounted on /mnt):
1.22 niklas 127: <pre>
1.99 ericj 128: # <b>cd /mnt; pax -rw CVS Makefile [a-z]* /usr/src</b>
1.22 niklas 129: </pre>
1.135 naddy 130: <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 131: <pre>
1.99 ericj 132: # <b>mount -t union -o -b /mnt /usr/src</b>
1.22 niklas 133: </pre>
1.23 mickey 134: </ul>
1.100 ericj 135:
136: <p>
1.142 naddy 137: 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>.
1.100 ericj 138: </p>
139:
140: <p>
1.135 naddy 141: 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.

1.135 naddy 144: <h3><a name="using"><font color="#0000e0">Using CVS to get and update your source tree</font></a></h3>
1.100 ericj 145:
146: <p>
1.109 jason 147: CVS was designed to be a simple way to retrieve and update your sources,
148: therefore there isn't much involved at all in doing so. You must first
149: decide whether you want to track <i>current</i> or a patch branch.
1.112 kjell 150: The current tree has all of the up to the minute changes,
1.109 jason 151: whereas a patch branch contains a formal release plus the patches
152: from the <a href="errata.html">errata</a> already applied.
153:
154: <p>Once you have decided which tree to follow, you much choose which Anonymous
155: CVS server you are going to use. A list of these servers is
1.135 naddy 156: <a href="#CVSROOT">below</a>. Do, however, notice that there are three ways
1.109 jason 157: to access these servers.
1.100 ericj 158: </p>
1.99 ericj 159:
1.135 naddy 160: <dl>
161: <dt><b>ssh</b><dd>Secure Shell can be used to access the anonymous CVS servers. This is the <em>recommended</em> way of doing so, as it is encrypted. As of 2.6, OpenBSD has included OpenSSH in its standard distribution.
1.140 horacio 162: <dt><b>rsh</b><dd>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>.
1.135 naddy 163: <dt><b>pserver</b><dd>pserver is primarily useful for users who are behind firewalls that block the other two connections.
164: </dl>
1.100 ericj 165:
166: <p>
1.135 naddy 167: <b>NOTE:</b> For users wishing to use ssh, you must first set the <var>CVS_RSH</var> variable to ssh.
1.100 ericj 168:
169: <ul>
1.135 naddy 170: <li>For Korn/Bourne shells:
1.100 ericj 171: <pre>
1.135 naddy 172: $ <b>export CVS_RSH=/usr/bin/ssh</b>
1.100 ericj 173: </pre>
1.135 naddy 174: <li>For csh/tcsh:
1.100 ericj 175: <pre>
1.135 naddy 176: % <b>setenv CVS_RSH /usr/bin/ssh</b>
1.100 ericj 177: </pre>
178: </ul>
179:
180: <p>
181: 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>.
182: </p>
183:
1.135 naddy 184: <pre>
185: # <b>cd /usr; cvs checkout -P src</b>
186: </pre>
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:
1.135 naddy 194: <pre>
195: # <b>cd /usr; cvs checkout -P -rOPENBSD_2_8 src</b>
196: </pre>
1.1 deraadt 197: <p>
1.129 millert 198: Or OPENBSD_2_7 for 2.7, etc.
1.100 ericj 199:
1.129 millert 200: <p> Currently only the OPENBSD_2_8 tag contains the release sources and
1.109 jason 201: errata already applied.

210: <dd>Developers who need to commit changes to the source tree must have

1.39 todd 499: Here is how someone using anoncvs regularly would update his
1.1 deraadt 500: source tree:
1.60 millert 501: <ul><li>First, start out by `get'-ing an initial tree:
1.27 todd 502:
1.109 jason 503: <p> (If you are following <i>current</i>):
1.135 naddy 504: <pre>
505: # <strong>setenv CVSROOT anoncvs@anoncvs.ca.openbsd.org:/cvs</strong>
506: # <strong>cd /usr</strong>
507: # <strong>cvs -q get -PA src</strong>
508: </pre>
1.109 jason 509:
1.129 millert 510: <p> (If you are following the patch branch for 2.8):
1.135 naddy 511: <pre>
512: # <strong>setenv CVSROOT anoncvs@anoncvs.ca.openbsd.org:/cvs</strong>
513: # <strong>cd /usr</strong>
514: # <strong>cvs -q get -rOPENBSD_2_8 -P src</strong>
515: </pre>
1.27 todd 516: </li>
1.37 todd 517:
1.27 todd 518: <li> Anytime afterwards, to `update' this tree:

527: # <strong>cd /usr/src</strong>
528: # <strong>cvs -q up -rOPENBSD_2_8 -Pd</strong>
529: </pre>
1.109 jason 530:
1.39 todd 531: Everytime you ran this it would synchronize your /usr/src tree. It would
1.1 deraadt 532: not destroy any of your local changes, rather it would attempt to merge
533: changes in. If you use obj directories (not obj symbolic links) you may
534: wish to append "-I obj" to the cvs command line, this will keep cvs from
535: spitting out a warning about all the obj directories it is going to
536: encounter which are not in the repository.

1.109 jason 539: <li> NOTES: if you are updating a source tree that you initially fetched
1.72 millert 540: from a different server, or from a CD, you <strong>must</strong>
1.145 marc 541: add the <em>-d $CVSROOT</em> options to cvs. If you are following
1.109 jason 542: a patch branch, be sure to always <strong>omit</strong> the <code>-A</code>
543: flag to cvs, or you may find yourself tracking <i>current</i> instead.

1.105 ericj 597: Anoncvs mirrors also carry the OpenBSD X11 source tree. You can adapt
598: the recipe above to update your X11 source tree from the second CD.
599: Either copy or use a union mount to get the X11 sources in <i>/usr/X11</i>:
600:
601: <ul>
602: <li>copy the tree off it (assuming the 2nd CD is mounted on /mnt):
603: <pre>
604: # <strong>cd /mnt; cp -Rp X11 /usr</strong>
605: </pre>
606: <li>use a union mount with the CD below a writable directory.

608: # <strong>mount -t union -o -b /mnt/X11 /usr/X11</strong>
1.135 naddy 609: </pre>
610: </ul>
1.105 ericj 611:
612: After this, <i>/usr/X11</i> will be ready to be used by cvs. You can for
613: example update it to -current source (assuming you've already set
1.140 horacio 614: the <var>CVSROOT</var> environment variable):
1.105 ericj 615:

1.105 ericj 620:
621: <p>
1.12 grr 622: <strong>Warning:</strong>
623: When using cvs you should take care that your current directory is either
1.109 jason 624: the root of the tree you are referencing or in a separate place such as /tmp.
1.12 grr 625: Some commands such as "get" can create an arbitrary sub-tree in the current

1.1 deraadt 629: The anoncvs service gives fledgling developers a chance to learn CVS
630: operation and get thoroughly involved in the development process
631: before getting "commit" access -- as a result of showing useful
632: skills and high quality results they will naturally later be given
633: developer access. As well, people providing patches can create

1.39 todd 643: of the CVS sites no longer support rsh for security reasons or a local
1.12 grr 644: problem like a firewall or imperfect protocol emulator such as slirp

1.28 beck 648:

658: Use something like the following in your <strong>$HOME/.ssh/config</strong>
1.10 millert 659: file. Note that not all anoncvs servers allow ssh connections on
1.21 millert 660: port 2022. Also note that most anoncvs servers no longer accept
