1.249 nick 45: Anonymous CVS is a method of keeping your local copy of the OpenBSD source
46: tree up to date with respect to changes made to current OpenBSD sources.
47: In addition to following the bleeding edge of development, it is
48: also possible to track the patches for errata of a release.
1.99 ericj 49:
1.14 downsj 50: <p>
1.249 nick 51: The major advantage of Anonymous CVS over other source code update
52: techniques is that it works directly against a central source code
53: repository or mirror. This means that you have the full set of CVS
54: commands available to control merging and updating your changes with
55: other source changes and for performing diffs, change histories
56: and other queries against the central repository.
1.99 ericj 57:
1.36 deraadt 58: <p>
1.282 nick 59: The OpenBSD Project currently has four active and two historic
60: source repositories:
1.99 ericj 61:
62: <ul>
1.249 nick 63: <li><b>src</b> - Houses all source code for the OpenBSD Operating System.
1.329 steven 64: <li><b>ports</b> - Houses the <a href="faq/ports/index.html">OpenBSD Ports</a>.
1.249 nick 65: <li><b>www</b> - Houses all OpenBSD web pages. (Including this one).
1.280 steven 66: <li><b>xenocara</b> - Houses OpenBSD's active X.org v7 source tree.
1.282 nick 67: <li><b>X11</b> and <b>XF4</b> - Houses OpenBSD's adaptation of the
68: <a href="http://www.XFree86.org/">XFree86-3</a> and XFree86-4
69: source trees.
70: These are here just for historical purposes, most users will have
71: no reason to use this tree, it is no longer being used.
1.99 ericj 72: </ul>
73:
1.100 ericj 74: <p>
1.249 nick 75: To summarize, the real strength of using Anonymous CVS is that it is
76: a "tolerant" source code control system - it <strong>respects</strong>
77: changes that you have made to your local sources and makes <strong>
78: "best efforts"</strong> to update your entire source tree, rather than
79: leaving you a list of arcane problems that have to be resolved before
80: continuing.
81:
82: <h3><a name="CVS"><font color="#0000e0">What is CVS?</font></a></h3>
83:
84: <p>
1.260 nick 85: <a href="http://ximbiot.com/cvs/">CVS</a> is the source code control
1.249 nick 86: system used to <a href="why-cvs.html">manage the OpenBSD source
87: tree.</a>
88: It implements a central repository for all officially released source code
89: and changes, while permitting developers to maintain local copies of the
90: source code with their working changes.
1.226 nick 91:
1.249 nick 92: There are two levels of source tree access:
1.226 nick 93: <ul>
1.249 nick 94: <li><b>Read-write access for developers:</b>
95: Developers who need to commit changes to the source tree must have an
96: account on the OpenBSD machines.
97: Getting this access will be a natural result of working on the sources
98: with other OpenBSD developers.
99: If someone does some good work and shows they can work with the team,
100: they will get an account.
101:
102: <li><b>Read-only access for everyone:</b>
103: Anyone can access the read-only CVS repositories.
104: These copies of the read-write CVS repository are mirrored often.
1.226 nick 105: </ul>
1.99 ericj 106:
1.15 grr 107: <p>
1.249 nick 108: The major strength of CVS is that it has the ability to perform intelligent
109: merges of changes to the central repository with changes that you make to
110: your local copy. This means that if you make a change to a module and
111: perform an update, your changes are not "blown away", rather CVS makes
112: best efforts to merge the changes made to the central sources with changes
113: you've made to your local copy.
114:
115: <p>
116: In the event that the changes can't be completely merged, CVS provides a
117: "soft fallback", providing you with annotated changes to your
118: local copy, preserving an unmodified copy of your version and continuing
119: to update any other source modules you requested.
120:
121: <h3><a name="starting"><font color="#0000e0">Getting Started Using Anonymous
122: CVS</font></a></h3>
123:
124: While you can download the entire source tree from an AnonCVS server,
125: you can often save a lot of time and bandwidth by "preloading" your
126: source tree with the source files from either the OpenBSD CD or from an
127: FTP server.
128: This is particularly true if you are running
129: <a href="stable.html"><i>-stable</i></a>, as relatively few files change
130: between the <i>-release</i> and <i>-stable</i>.
1.100 ericj 131:
1.22 niklas 132: <p>
1.249 nick 133: To extract the source tree from the CD to <i>/usr/src</i> (assuming the CD is
134: mounted on /mnt):
1.22 niklas 135: <pre>
1.280 steven 136: # <b>cd /usr/src</b>
137: # <b>tar xzf /mnt/src.tar.gz</b>
1.282 nick 138: # <b>cd /usr</b>
1.280 steven 139: # <b>tar xzf /mnt/xenocara.tar.gz</b>
1.226 nick 140: # <b>tar xzf /mnt/ports.tar.gz</b>
1.22 niklas 141: </pre>
1.224 nick 142:
1.249 nick 143: The source files for download from the FTP servers are separated into two
144: files to minimize the time required to download for those wishing to work
145: with only one part of the tree. The two files are <tt>sys.tar.gz</tt>,
146: which contains the files used to create the kernel, and <tt>src.tar.gz</tt>
147: which contains all the other "userland" utilities.
148: In general, however, you will usually want both of them installed.
1.280 steven 149: Assuming the downloaded files, <tt>src.tar.gz</tt>,
150: <tt>sys.tar.gz</tt> and <tt>xenocara.tar.gz</tt> are in <tt>/usr</tt>:
1.224 nick 151:
1.22 niklas 152: <pre>
1.224 nick 153: # <b>cd /usr/src</b>
154: # <b>tar xzf ../sys.tar.gz</b>
1.225 nick 155: # <b>tar xzf ../src.tar.gz</b>
1.282 nick 156: # <b>cd /usr</b>
1.284 steven 157: # <b>tar xzf xenocara.tar.gz</b>
1.226 nick 158: # <b>tar xzf ports.tar.gz</b>
1.22 niklas 159: </pre>
1.100 ericj 160:
161: <p>
1.249 nick 162: Not all people will wish to unpack all the file sets, but as the system
163: must be kept in sync, you will generally need to set up all trees.
1.226 nick 164:
165: <p>
1.249 nick 166: You can also just use cvs(1) to "<b>checkout</b>" the source repository
167: for you. This is discussed in the <a href="#using">next section</a>.
1.100 ericj 168:
169: <p>
1.249 nick 170: After this, <tt>/usr/src</tt> will be a nice checkout area where all
171: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cvs&sektion=1&format=html">
172: cvs(1)</a> commands will work properly.
1.100 ericj 173:
1.249 nick 174: <h3><a name="using"><font color="#0000e0">Using CVS to get and update your
175: source tree</font></a></h3>
1.100 ericj 176:
177: <p>
1.249 nick 178: CVS was designed to be a simple way to retrieve and update your sources.
179: You must first decide whether you want to track <i>-current</i> or a
180: <a href="stable.html">patch branch</a>.
181: The current tree has all of the up to the minute changes,
182: whereas a patch branch contains a formal release plus the patches
183: from the <a href="errata.html">errata</a> and lesser issues already applied.
184: For more information on these "flavors" of OpenBSD, see
185: <a href="faq/faq5.html#Flavors">here</a>.
186:
187: <p>Once you have decided which tree to follow, you must choose which Anonymous
188: CVS server you are going to use. A list of these servers is
189: <a href="#CVSROOT">below</a>.
190:
191: <p>
192: Once you have chosen which <a href="#CVSROOT">Anonymous CVS Server</a> you will
193: use, you can start using cvs. For those of you
194: who have CDs you can start with the CVS checkout that is on the CD by using
195: the method <a href="#starting">above</a> to get the sources onto your system.
196: If you don't have a CD handy, use the method below to checkout the sources.
197: This method puts the OpenBSD source tree into <i>/usr/src</i>.

1.249 nick 204: The above will checkout the <i>current</i> source tree. Many of you will
205: only want the patch branch sources. To checkout a patch branch, you must
