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

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

1.135 naddy 83: <a href="why-cvs.html">
1.36 deraadt 84: CVS is the source code control system used to manage the OpenBSD source tree.</a>
1.16 deraadt 85: It implements a central repository for all officially released source code
1.15 grr 86: and changes, while permitting developers to maintain local copies of the
1.99 ericj 87: source code with their working changes. Developers with "<b>write access</b>"
1.15 grr 88: can commit changes directly to the OpenBSD source tree, while "Anonymous
1.155 jsyn 89: CVS" users have "<b>read access</b>" and can keep their local copies of the
1.169 miod 90: source up to date and issue queries against the central repository.
1.99 ericj 91: </p>
92:
1.15 grr 93: <p>
1.22 niklas 94: The major strength of CVS is that it has the ability to perform intelligent
1.15 grr 95: merges of changes to the central repository with changes that you make to
96: your local copy. This means that if you make a change to a module and
97: perform an update, your changes are not "blown away", rather CVS makes
98: best efforts to merge the changes made to the central sources with changes
99: you've made to your local copy.
1.99 ericj 100: </p>
101:
1.15 grr 102: <p>
103: In the event that the changes can't be completely merged, CVS provides a
104: "soft fallback", in terms of providing you with annotated changes to your
1.39 todd 105: local copy, preserving an unmodified copy of your version and continuing
1.15 grr 106: to update any other source modules you requested.

1.99 ericj 120: People who own an OpenBSD CD may have seen the <i>CVS/</i> dirs on it.
1.155 jsyn 121: Actually there is a reason, the CD has a checkout of the OpenBSD <b>src</b>
122: module usable to continue updating from. Using this tree will result in a much
1.23 mickey 123: faster initial CVS update than a fresh checkout of the full OpenBSD
124: source tree. There are two ways of using the CD:
1.99 ericj 125: </p>
126:
1.23 mickey 127: <ul>
1.155 jsyn 128: <li>To copy the CVS tree from the CD to <i>/usr/src</i> (assuming the CD is
129: mounted on /mnt):
1.22 niklas 130: <pre>
1.99 ericj 131: # <b>cd /mnt; pax -rw CVS Makefile [a-z]* /usr/src</b>
1.22 niklas 132: </pre>
1.155 jsyn 133: <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>)
134: with the CD below a writable directory. (This can be used when only compiling from the tree.)
1.22 niklas 135: <pre>
1.99 ericj 136: # <b>mount -t union -o -b /mnt /usr/src</b>
1.22 niklas 137: </pre>
1.23 mickey 138: </ul>
1.100 ericj 139:
140: <p>
1.155 jsyn 141: 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">
142: cvs(1)</a> to "<b>checkout</b>" the source repository for you. This is
143: discussed in the <a href="#using">next section</a>.
1.100 ericj 144: </p>
145:
146: <p>
1.155 jsyn 147: After this, <i>/usr/src</i> will be a nice checkout area where all
148: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cvs&sektion=1&format=html">
149: cvs(1)</a> commands will work OK.

155: <p>
1.109 jason 156: CVS was designed to be a simple way to retrieve and update your sources,
157: therefore there isn't much involved at all in doing so. You must first
158: decide whether you want to track <i>current</i> or a patch branch.
1.112 kjell 159: The current tree has all of the up to the minute changes,
1.109 jason 160: whereas a patch branch contains a formal release plus the patches
1.157 heko 161: from the <a href="errata.html">errata</a> already applied. For a definition
162: of <i>current</i>, see the <a href="faq/upgrade-minifaq.html#1.1">Upgrade
163: Mini-FAQ</a>.
1.109 jason 164:
1.169 miod 165: <p>Once you have decided which tree to follow, you must choose which Anonymous
1.109 jason 166: CVS server you are going to use. A list of these servers is
1.135 naddy 167: <a href="#CVSROOT">below</a>. Do, however, notice that there are three ways
1.109 jason 168: to access these servers.

1.155 jsyn 172: <dt><b>ssh</b><dd>Secure Shell can be used to access the anonymous CVS servers.
173: This is the <em>recommended</em> way of doing so, as it is encrypted. As of
174: 2.6, OpenBSD has included OpenSSH in its standard distribution.
175: <dt><b>rsh</b><dd>Remote Shell can be used on some of the servers for users
176: who don't have access to <a href="http://www.openssh.com/">ssh</a>.
177: <dt><b>pserver</b><dd>pserver is primarily useful for users who are behind

1.100 ericj 180:
181: <p>
1.159 jcs 182: <b>NOTE:</b> For users wishing to use rsh, you must first set the

1.100 ericj 184:

1.135 naddy 186: <li>For Korn/Bourne shells:

198: use, and which method you will use, you can start using cvs. For those of you
199: who have CDs you can start with the CVS checkout that is on the CD by using
200: the method <a href="#starting">above</a> to get the sources onto your system.
201: If you don't have a CD handy, use the method below to checkout the sources.

1.109 jason 210: The above will checkout the <i>current</i> source tree. Many of you will
1.169 miod 211: only want the patch branch sources. To checkout a patch branch, you must
1.109 jason 212: specify a tag along with your command. Example:

1.1 deraadt 625: The anoncvs service gives fledgling developers a chance to learn CVS

640: Many of the CVS sites no longer support rsh for security reasons. Local
