36: <b>CVSync</b> is a software package for distributing and updating source
37: trees from a master <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cvs&sektion=1">cvs(1)</a> repository on a remote server host. The OpenBSD
38: sources are maintained in a CVS repository on a central development machine
39: in Canada. With CVSync, OpenBSD users can easily keep their own source trees
1.10 naddy 40: up to date.
1.1 espie 41: </p>
42:
43: <p>
44: <b>CVSync</b> uses the so-called pull model of updating. Under the pull
45: model, each client asks the server for updates, if and when they are
46: wanted. The server waits passively for update requests from its clients.
47: Thus all updates are instigated by the client. The server never sends
48: unsolicited updates. Users must either run the <b>CVSync</b> client
49: manually to get an update, or they must set up a <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cron&sektion=8">cron(8)</a> job to run it
1.10 naddy 50: automatically on a regular basis.
1.1 espie 51: </p>
52:
53: <p>
54: The term <b>CVSync</b>, capitalized just so, refers to the entire software
55: package. Its main components are the client <tt>cvsync</tt> which runs on
56: each user's machine, and the server <tt>cvsyncd</tt> which runs at each of
1.10 naddy 57: the OpenBSD CVSync mirror sites.

67: The OpenBSD Project currently has five main source repositories:
68: </p>
69:
70: <ul>
71: <li><b>src</b> - Houses all source code for the OpenBSD Operating System.</li>
72: <li><b>ports</b> - Houses the <a href="./ports.html">OpenBSD Ports</a>.</li>
1.10 naddy 73: <li><b>www</b> - Houses all OpenBSD web pages (including this one).</li>
1.26 matthieu 74: <li><b>X11</b> - Houses OpenBSD's adaptation of the
75: <a href="http://www.XFree86.org/">XFree86-3</a> software project.
76: This is here just for historical purposes, most users will have no
77: reason to use this tree, it is no longer being used.
78: <li><b>XF4</b> - Houses OpenBSD's active X source tree.

81: <h3><a name="CVS"><font color="#0000e0">What Is CVS?</font></a></h3>
82:
83: <p>
84: CVS is the source code control system used to manage the OpenBSD source
85: tree. It is described in more detail <a href="anoncvs.html#CVS">here</a>.
86: Note that CVS and CVSync are entirely different programs. Although
87: CVS can be used for remote file access, it is not optimized for
88: wholesale source tree distribution over the net, and CVSync can be
89: easily an order of magnitude more efficient for this task.

95:
96: <p>
97: If you only care about running CVSync, it is recommended that you
98: download the cvsync package from the <a href="ftp.html">ftp mirror
99: sites</a> instead of building your own from the <tt>net/cvsync</tt>
1.10 naddy 100: port.

105: <a href="http://www.cvsync.org/">project homepage</a>.
106: </p>
107:
108: <p>
109: In order to mirror the OpenBSD repository with CVSync,
110: the following configuration file might be used:
111: </p>
112:
113: <pre>
114: config {
115: hostname anoncvs.de.openbsd.org
1.5 naddy 116: # If your network link is a T1 or faster, comment out the following line.
1.1 espie 117: compress
1.4 espie 118: collection {
1.5 naddy 119: name openbsd release rcs
1.4 espie 120: prefix /cvs
1.5 naddy 121: umask 002
1.4 espie 122: }
1.1 espie 123: }
124: </pre>
125:
126: <p>
127: This directs cvsync to refresh all OpenBSD distributions from
128: <b>anoncvs.de.openbsd.org</b> with a <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=umask&sektion=2">umask(2)</a> that permits group write
129: permission to the local repository.
130: </p>
131:
132: <p>
133: Assuming this file is saved as <tt>cvs-syncfile</tt>, the
134: following command would be used to invoke cvsync
135: </p>
136: <pre>
137: cvsync -c cvs-syncfile
138: </pre>

1.32 ray 145: It is now simple to check out any one of the CVSync'ed repositories:
1.1 espie 146: </p>
147: <pre>
148: # cd /usr
1.32 ray 149: # cvs -d /cvs checkout src
1.1 espie 150: </pre>
151:
152: <p>
153: The above will check out the most current sources. Many of you will only
154: want the release sources, especially if you are patching your system. To
155: checkout release sources you must specify a tag along with your command.
156: For example:
157: </p>
158: <pre>
159: # cd /usr
1.32 ray 160: # cvs -d /cvs checkout -rOPENBSD_3_5 src

285: </p>
286: <ul>

289: The OpenBSD sources are from Canada. As

292: <a href="http://axion.physics.ubc.ca/ECL.html">
293: described in the Export Control list of Canada</a>,
294: it is legal to export crypto software from Canada to the world.
295: </p>

299: However, if you are outside the USA or Canada, you should not
