1.249 nick 44: Anonymous CVS is a method of keeping your local copy of the OpenBSD source
45: tree up to date with respect to changes made to current OpenBSD sources.
46: In addition to following the bleeding edge of development, it is
47: also possible to track the patches for errata of a release.
1.99 ericj 48:
1.14 downsj 49: <p>
1.249 nick 50: The major advantage of Anonymous CVS over other source code update
51: techniques is that it works directly against a central source code
52: repository or mirror. This means that you have the full set of CVS
53: commands available to control merging and updating your changes with
54: other source changes and for performing diffs, change histories
55: and other queries against the central repository.
1.99 ericj 56:
1.36 deraadt 57: <p>
1.282 nick 58: The OpenBSD Project currently has four active and two historic
59: source repositories:
1.99 ericj 60:
61: <ul>
1.249 nick 62: <li><b>src</b> - Houses all source code for the OpenBSD Operating System.
63: <li><b>ports</b> - Houses the <a href="./ports.html">OpenBSD Ports</a>.
64: <li><b>www</b> - Houses all OpenBSD web pages. (Including this one).
1.280 steven 65: <li><b>xenocara</b> - Houses OpenBSD's active X.org v7 source tree.
1.282 nick 66: <li><b>X11</b> and <b>XF4</b> - Houses OpenBSD's adaptation of the
67: <a href="http://www.XFree86.org/">XFree86-3</a> and XFree86-4
68: source trees.
69: These are here just for historical purposes, most users will have
70: no reason to use this tree, it is no longer being used.
1.99 ericj 71: </ul>
72:
1.100 ericj 73: <p>
1.249 nick 74: To summarize, the real strength of using Anonymous CVS is that it is
75: a "tolerant" source code control system - it <strong>respects</strong>
76: changes that you have made to your local sources and makes <strong>
77: "best efforts"</strong> to update your entire source tree, rather than
78: leaving you a list of arcane problems that have to be resolved before
79: continuing.
80:
81: <h3><a name="CVS"><font color="#0000e0">What is CVS?</font></a></h3>
82:
83: <p>
1.260 nick 84: <a href="http://ximbiot.com/cvs/">CVS</a> is the source code control
1.249 nick 85: system used to <a href="why-cvs.html">manage the OpenBSD source
86: tree.</a>
87: It implements a central repository for all officially released source code
88: and changes, while permitting developers to maintain local copies of the
89: source code with their working changes.
1.226 nick 90:
1.249 nick 91: There are two levels of source tree access:
1.226 nick 92: <ul>
1.249 nick 93: <li><b>Read-write access for developers:</b>
94: Developers who need to commit changes to the source tree must have an
95: account on the OpenBSD machines.
96: Getting this access will be a natural result of working on the sources
97: with other OpenBSD developers.
98: If someone does some good work and shows they can work with the team,
99: they will get an account.
100:
101: <li><b>Read-only access for everyone:</b>
102: Anyone can access the read-only CVS repositories.
103: These copies of the read-write CVS repository are mirrored often.
1.226 nick 104: </ul>
1.99 ericj 105:
1.15 grr 106: <p>
1.249 nick 107: The major strength of CVS is that it has the ability to perform intelligent
108: merges of changes to the central repository with changes that you make to
109: your local copy. This means that if you make a change to a module and
110: perform an update, your changes are not "blown away", rather CVS makes
111: best efforts to merge the changes made to the central sources with changes
112: you've made to your local copy.
113:
114: <p>
115: In the event that the changes can't be completely merged, CVS provides a
116: "soft fallback", providing you with annotated changes to your
117: local copy, preserving an unmodified copy of your version and continuing
118: to update any other source modules you requested.
119:
120: <h3><a name="starting"><font color="#0000e0">Getting Started Using Anonymous
121: CVS</font></a></h3>
122:
123: While you can download the entire source tree from an AnonCVS server,
124: you can often save a lot of time and bandwidth by "preloading" your
125: source tree with the source files from either the OpenBSD CD or from an
126: FTP server.
127: This is particularly true if you are running
128: <a href="stable.html"><i>-stable</i></a>, as relatively few files change
129: between the <i>-release</i> and <i>-stable</i>.
1.100 ericj 130:
1.22 niklas 131: <p>
1.249 nick 132: To extract the source tree from the CD to <i>/usr/src</i> (assuming the CD is
133: mounted on /mnt):
1.22 niklas 134: <pre>
1.280 steven 135: # <b>cd /usr/src</b>
136: # <b>tar xzf /mnt/src.tar.gz</b>
1.282 nick 137: # <b>cd /usr</b>
1.280 steven 138: # <b>tar xzf /mnt/xenocara.tar.gz</b>
1.226 nick 139: # <b>tar xzf /mnt/ports.tar.gz</b>
1.22 niklas 140: </pre>
1.224 nick 141:
1.249 nick 142: The source files for download from the FTP servers are separated into two
143: files to minimize the time required to download for those wishing to work
144: with only one part of the tree. The two files are <tt>sys.tar.gz</tt>,
145: which contains the files used to create the kernel, and <tt>src.tar.gz</tt>
146: which contains all the other "userland" utilities.
147: In general, however, you will usually want both of them installed.
1.280 steven 148: Assuming the downloaded files, <tt>src.tar.gz</tt>,
149: <tt>sys.tar.gz</tt> and <tt>xenocara.tar.gz</tt> are in <tt>/usr</tt>:
1.224 nick 150:
1.22 niklas 151: <pre>
1.224 nick 152: # <b>cd /usr/src</b>
153: # <b>tar xzf ../sys.tar.gz</b>
1.225 nick 154: # <b>tar xzf ../src.tar.gz</b>
1.282 nick 155: # <b>cd /usr</b>
1.284 steven 156: # <b>tar xzf xenocara.tar.gz</b>
1.226 nick 157: # <b>tar xzf ports.tar.gz</b>
1.22 niklas 158: </pre>
1.100 ericj 159:
160: <p>
1.249 nick 161: Not all people will wish to unpack all the file sets, but as the system
162: must be kept in sync, you will generally need to set up all trees.
1.226 nick 163:
164: <p>
1.249 nick 165: You can also just use cvs(1) to "<b>checkout</b>" the source repository
166: for you. This is discussed in the <a href="#using">next section</a>.
1.100 ericj 167:
168: <p>
1.249 nick 169: After this, <tt>/usr/src</tt> will be a nice checkout area where all
170: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cvs&sektion=1&format=html">
171: cvs(1)</a> commands will work properly.
1.100 ericj 172:
1.249 nick 173: <h3><a name="using"><font color="#0000e0">Using CVS to get and update your
174: source tree</font></a></h3>
1.100 ericj 175:
176: <p>
1.249 nick 177: CVS was designed to be a simple way to retrieve and update your sources.
178: You must first decide whether you want to track <i>-current</i> or a
179: <a href="stable.html">patch branch</a>.
180: The current tree has all of the up to the minute changes,
181: whereas a patch branch contains a formal release plus the patches
182: from the <a href="errata.html">errata</a> and lesser issues already applied.
183: For more information on these "flavors" of OpenBSD, see
184: <a href="faq/faq5.html#Flavors">here</a>.
185:
186: <p>Once you have decided which tree to follow, you must choose which Anonymous
187: CVS server you are going to use. A list of these servers is
188: <a href="#CVSROOT">below</a>.
189:
190: <p>
191: Once you have chosen which <a href="#CVSROOT">Anonymous CVS Server</a> you will
192: use, you can start using cvs. For those of you
193: who have CDs you can start with the CVS checkout that is on the CD by using
194: the method <a href="#starting">above</a> to get the sources onto your system.
195: If you don't have a CD handy, use the method below to checkout the sources.
196: This method puts the OpenBSD source tree into <i>/usr/src</i>.
1.100 ericj 197:
1.135 naddy 198: <pre>
199: # <b>cd /usr; cvs checkout -P src</b>
200: </pre>
1.99 ericj 201:
1.1 deraadt 202: <p>
1.249 nick 203: The above will checkout the <i>current</i> source tree. Many of you will
204: only want the patch branch sources. To checkout a patch branch, you must
205: specify a tag along with your command. Example:
1.1 deraadt 206:
1.135 naddy 207: <pre>
1.299 landry 208: # <b>cd /usr; cvs checkout -P -rOPENBSD_4_5 src</b>
1.135 naddy 209: </pre>
1.1 deraadt 210: <p>
1.299 landry 211: Or OPENBSD_4_4 for 4.4, etc.
1.100 ericj 212:
1.299 landry 213: <p> The OPENBSD_4_5 tag contains the release sources and
1.249 nick 214: errata already applied.
