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>

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>

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.

1.224 ! nick 112: While you can download the entire source tree from an AnonCVS server,
! 113: you can often save a lot of time and bandwidth by "preloading" your
! 114: source tree with the source files from either the OpenBSD CD or from an
! 115: FTP server.
! 116: This is particularly true if you are running
! 117: <a href="stable.html"><i>-stable</i></a>, as relatively few files change
! 118: between the <i>-release</i> and <i>-stable</i>.
1.100 ericj 119:
1.22 niklas 120: <p>
1.224 ! nick 121: To extract the source tree from the CD to <i>/usr/src</i> (assuming the CD is
1.155 jsyn 122: mounted on /mnt):
1.22 niklas 123: <pre>
1.224 ! nick 124: # <b>cd /usr/src; tar xzf /mnt/src.tar.gz</b>
1.22 niklas 125: </pre>
1.224 ! nick 126:
! 127: The source files for download from the FTP servers are separated into two
! 128: files to minimize the time required to download for those wishing to work
! 129: with only one part of the tree. The two files are <tt>sys.tar.gz</tt>,
! 130: which contains the files used to create the kernel, and <tt>src.tar.gz</tt>
! 131: which contains all the other "userland" utilties.
! 132: In general, however, you will usually want both of them installed.
! 133: Assuming the downloaded files, <tt>src.tar.gz</tt> and
! 134: <tt>sys.tar.gz</tt> are in <tt>/usr</tt>:
! 135:
1.22 niklas 136: <pre>
1.224 ! nick 137: # <b>cd /usr/src</b>
! 138: # <b>tar xzf ../sys.tar.gz</b>
! 139: # <b>tar xzf ../src.sys.gz</b>
1.22 niklas 140: </pre>
1.100 ericj 141:
142: <p>
1.224 ! nick 143: You can also just use cvs(1) to "<b>checkout</b>" the source repository
! 144: for you. This is discussed in the <a href="#using">next section</a>.
1.100 ericj 145:
146: <p>
1.155 jsyn 147: After this, <i>/usr/src</i> will be a nice checkout area where all

1.109 jason 155: CVS was designed to be a simple way to retrieve and update your sources,
156: therefore there isn't much involved at all in doing so. You must first
157: decide whether you want to track <i>current</i> or a patch branch.
1.112 kjell 158: The current tree has all of the up to the minute changes,
1.109 jason 159: whereas a patch branch contains a formal release plus the patches

172: This is the <em>recommended</em> way of doing so, as it is encrypted. As of
173: 2.6, OpenBSD has included OpenSSH in its standard distribution.
174: <dt><b>rsh</b><dd>Remote Shell can be used on some of the servers for users

1.12 grr 632: Some commands such as "get" can create an arbitrary sub-tree in the current

634:
635: <p>
1.1 deraadt 636: The anoncvs service gives fledgling developers a chance to learn CVS
637: operation and get thoroughly involved in the development process
638: before getting "commit" access -- as a result of showing useful
639: skills and high quality results they will naturally later be given

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