26:
27: <p>
28: <b>CVSync</b> is a software package for distributing and updating source
1.120 sthen 29: trees from a master <a href="http://man.openbsd.org/?query=cvs&sektion=1">cvs(1)</a> repository on a remote server host. The OpenBSD
1.1 espie 30: sources are maintained in a CVS repository on a central development machine
31: in Canada. With CVSync, OpenBSD users can easily keep their own source trees
1.10 naddy 32: up to date.
1.1 espie 33: </p>
34:
35: <p>
36: <b>CVSync</b> uses the so-called pull model of updating. Under the pull
37: model, each client asks the server for updates, if and when they are
38: wanted. The server waits passively for update requests from its clients.
39: Thus all updates are instigated by the client. The server never sends
40: unsolicited updates. Users must either run the <b>CVSync</b> client
1.120 sthen 41: manually to get an update, or they must set up a <a href="http://man.openbsd.org/?query=cron&sektion=8">cron(8)</a> job to run it
1.10 naddy 42: automatically on a regular basis.
1.1 espie 43: </p>
44:
45: <p>
46: The term <b>CVSync</b>, capitalized just so, refers to the entire software
47: package. Its main components are the client <tt>cvsync</tt> which runs on
48: each user's machine, and the server <tt>cvsyncd</tt> which runs at each of
1.10 naddy 49: the OpenBSD CVSync mirror sites.
1.1 espie 50: </p>
51:
52: <p>
1.23 nick 53: <b>CVSync</b> is intended to be both faster and more flexible than
1.97 tedu 54: sup and CVSup.

57: <p>
1.42 nick 58: The OpenBSD Project currently has six main source repositories:
1.1 espie 59: </p>
60:
61: <ul>
62: <li><b>src</b> - Houses all source code for the OpenBSD Operating System.</li>
1.78 steven 63: <li><b>ports</b> - Houses the <a href="faq/ports/index.html">OpenBSD Ports</a>.</li>
1.10 naddy 64: <li><b>www</b> - Houses all OpenBSD web pages (including this one).</li>
1.26 matthieu 65: <li><b>X11</b> - Houses OpenBSD's adaptation of the
66: <a href="http://www.XFree86.org/">XFree86-3</a> software project.
1.51 deraadt 67: <li><b>XF4</b> - Houses OpenBSD's adaptation of the XFree86-4 source tree.
68: <li><b>xenocara</b> - Houses OpenBSD's active X.org v7 source tree.
1.1 espie 69: </ul>
70:
1.84 jasper 71: The <b>X11</b> and <b>XF4</b> repositories are here just for historical
1.97 tedu 72: purposes, most users will have no reason to use those trees, they are no longer
1.84 jasper 73: being used.

1.1 espie 75: <h3><a name="CVS"><font color="#0000e0">What Is CVS?</font></a></h3>
76:
77: <p>
78: CVS is the source code control system used to manage the OpenBSD source
79: tree. It is described in more detail <a href="anoncvs.html#CVS">here</a>.
80: Note that CVS and CVSync are entirely different programs. Although
81: CVS can be used for remote file access, it is not optimized for
82: wholesale source tree distribution over the net, and CVSync can be
83: easily an order of magnitude more efficient for this task.
84: </p>

86: <h3>
87: <a name="starting"><font color="#0000e0">Getting Started Using CVSync</font></a>
88: </h3>
89:
90: <p>
91: If you only care about running CVSync, it is recommended that you
92: download the cvsync package from the <a href="ftp.html">ftp mirror
93: sites</a> instead of building your own from the <tt>net/cvsync</tt>
1.10 naddy 94: port.
1.1 espie 95: </p>
96:
97: <p>
98: For further information about CVSync, see the
99: <a href="http://www.cvsync.org/">project homepage</a>.
1.116 sthen 100: However, don't build your own copy from unmodified upstream source -
101: the port/package has been modified to support commitid which is now
102: used in the OpenBSD repository.
1.1 espie 103: </p>
104:
105: <p>
106: In order to mirror the OpenBSD repository with CVSync,
107: the following configuration file might be used:
108: </p>
109:
110: <pre>
111: config {
1.103 mpi 112: hostname anoncvs.eu.openbsd.org
1.5 naddy 113: # If your network link is a T1 or faster, comment out the following line.
1.1 espie 114: compress
1.4 espie 115: collection {
1.5 naddy 116: name openbsd release rcs
1.4 espie 117: prefix /cvs
1.5 naddy 118: umask 002
1.4 espie 119: }
1.1 espie 120: }
121: </pre>
122:
123: <p>
124: This directs cvsync to refresh all OpenBSD distributions from
1.120 sthen 125: <b>anoncvs.eu.openbsd.org</b> with a <a href="http://man.openbsd.org/?query=umask&sektion=2">umask(2)</a> that permits group write
1.1 espie 126: permission to the local repository.
127: </p>
128:
129: <p>
130: Assuming this file is saved as <tt>cvs-syncfile</tt>, the
131: following command would be used to invoke cvsync
132: </p>
133: <pre>

280: The OpenBSD sources are from Canada. As

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