36: <p>
37: <b>CVSync</b> is a software package for distributing and updating source
38: 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
39: sources are maintained in a CVS repository on a central development machine
40: in Canada. With CVSync, OpenBSD users can easily keep their own source trees
1.10 naddy 41: up to date.
1.1 espie 42: </p>
43:
44: <p>
45: <b>CVSync</b> uses the so-called pull model of updating. Under the pull
46: model, each client asks the server for updates, if and when they are
47: wanted. The server waits passively for update requests from its clients.
48: Thus all updates are instigated by the client. The server never sends
49: unsolicited updates. Users must either run the <b>CVSync</b> client
50: 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 51: automatically on a regular basis.
1.1 espie 52: </p>
53:
54: <p>
55: The term <b>CVSync</b>, capitalized just so, refers to the entire software
56: package. Its main components are the client <tt>cvsync</tt> which runs on
57: each user's machine, and the server <tt>cvsyncd</tt> which runs at each of
1.10 naddy 58: the OpenBSD CVSync mirror sites.

61: <p>
1.23 nick 62: <b>CVSync</b> is intended to be both faster and more flexible than

1.42 nick 67: The OpenBSD Project currently has six main source repositories:
1.1 espie 68: </p>
69:
70: <ul>
71: <li><b>src</b> - Houses all source code for the OpenBSD Operating System.</li>
1.78 steven 72: <li><b>ports</b> - Houses the <a href="faq/ports/index.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.
1.51 deraadt 76: <li><b>XF4</b> - Houses OpenBSD's adaptation of the XFree86-4 source tree.
77: <li><b>xenocara</b> - Houses OpenBSD's active X.org v7 source tree.
1.1 espie 78: </ul>
79:
1.84 jasper 80: The <b>X11</b> and <b>XF4</b> repositories are here just for historical
1.97 tedu 81: purposes, most users will have no reason to use those trees, they are no longer
1.84 jasper 82: being used.

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

95: <h3>
96: <a name="starting"><font color="#0000e0">Getting Started Using CVSync</font></a>
97: </h3>
98:
99: <p>
100: If you only care about running CVSync, it is recommended that you
101: download the cvsync package from the <a href="ftp.html">ftp mirror
102: sites</a> instead of building your own from the <tt>net/cvsync</tt>
1.10 naddy 103: port.
1.1 espie 104: </p>
105:
106: <p>
107: For further information about CVSync, see the
108: <a href="http://www.cvsync.org/">project homepage</a>.
109: </p>
110:
111: <p>
112: In order to mirror the OpenBSD repository with CVSync,
113: the following configuration file might be used:
114: </p>
115:
116: <pre>
117: config {
1.103 mpi 118: hostname anoncvs.eu.openbsd.org
1.5 naddy 119: # If your network link is a T1 or faster, comment out the following line.
1.1 espie 120: compress
1.4 espie 121: collection {
1.5 naddy 122: name openbsd release rcs
1.4 espie 123: prefix /cvs
1.5 naddy 124: umask 002
1.4 espie 125: }
1.1 espie 126: }
127: </pre>
128:
129: <p>
130: This directs cvsync to refresh all OpenBSD distributions from
1.103 mpi 131: <b>anoncvs.eu.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
1.1 espie 132: permission to the local repository.

136: Assuming this file is saved as <tt>cvs-syncfile</tt>, the
