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>
1.261 nick 58: The OpenBSD Project currently has six main source repositories:
1.99 ericj 59:
60: <ul>
1.249 nick 61: <li><b>src</b> - Houses all source code for the OpenBSD Operating System.
62: <li><b>ports</b> - Houses the <a href="./ports.html">OpenBSD Ports</a>.
63: <li><b>www</b> - Houses all OpenBSD web pages. (Including this one).
64: <li><b>X11</b> - Houses OpenBSD's adaptation of the
65: <a href="http://www.XFree86.org/">XFree86-3</a> software project.
66: This is here just for historical purposes, most users will have no
67: reason to use this tree, it is no longer being used.
68: <li><b>XF4</b> - Houses OpenBSD's active X source tree.
1.259 nick 69: <li><b>xenocara</b> - Houses OpenBSD's in-development X.org v7 tree.
1.99 ericj 70: </ul>
71:
1.100 ericj 72: <p>
1.249 nick 73: To summarize, the real strength of using Anonymous CVS is that it is
74: a "tolerant" source code control system - it <strong>respects</strong>
75: changes that you have made to your local sources and makes <strong>
76: "best efforts"</strong> to update your entire source tree, rather than
77: leaving you a list of arcane problems that have to be resolved before
78: continuing.
79:
80: <h3><a name="CVS"><font color="#0000e0">What is CVS?</font></a></h3>
81:
82: <p>
1.260 nick 83: <a href="http://ximbiot.com/cvs/">CVS</a> is the source code control
1.249 nick 84: system used to <a href="why-cvs.html">manage the OpenBSD source
85: tree.</a>
86: It implements a central repository for all officially released source code
87: and changes, while permitting developers to maintain local copies of the
88: source code with their working changes.
1.226 nick 89:
1.249 nick 90: There are two levels of source tree access:
1.226 nick 91: <ul>
1.249 nick 92: <li><b>Read-write access for developers:</b>
93: Developers who need to commit changes to the source tree must have an
94: account on the OpenBSD machines.
95: Getting this access will be a natural result of working on the sources
96: with other OpenBSD developers.
97: If someone does some good work and shows they can work with the team,
98: they will get an account.
99:
100: <li><b>Read-only access for everyone:</b>
101: Anyone can access the read-only CVS repositories.
102: These copies of the read-write CVS repository are mirrored often.
1.226 nick 103: </ul>
1.99 ericj 104:
1.15 grr 105: <p>
1.249 nick 106: The major strength of CVS is that it has the ability to perform intelligent
107: merges of changes to the central repository with changes that you make to
108: your local copy. This means that if you make a change to a module and
109: perform an update, your changes are not "blown away", rather CVS makes
110: best efforts to merge the changes made to the central sources with changes
111: you've made to your local copy.
112:
113: <p>
114: In the event that the changes can't be completely merged, CVS provides a
115: "soft fallback", providing you with annotated changes to your
116: local copy, preserving an unmodified copy of your version and continuing
117: to update any other source modules you requested.
118:
119: <h3><a name="starting"><font color="#0000e0">Getting Started Using Anonymous
120: CVS</font></a></h3>
121:
122: While you can download the entire source tree from an AnonCVS server,
123: you can often save a lot of time and bandwidth by "preloading" your
124: source tree with the source files from either the OpenBSD CD or from an
125: FTP server.
126: This is particularly true if you are running
127: <a href="stable.html"><i>-stable</i></a>, as relatively few files change
128: between the <i>-release</i> and <i>-stable</i>.
1.100 ericj 129:
1.22 niklas 130: <p>
1.249 nick 131: To extract the source tree from the CD to <i>/usr/src</i> (assuming the CD is
132: mounted on /mnt):
1.22 niklas 133: <pre>
1.224 nick 134: # <b>cd /usr/src; tar xzf /mnt/src.tar.gz</b>
1.227 nick 135: # <b>cd /usr; tar xzf /mnt/XF4.tar.gz</b>
1.226 nick 136: # <b>tar xzf /mnt/ports.tar.gz</b>
1.22 niklas 137: </pre>
1.224 nick 138:
1.249 nick 139: The source files for download from the FTP servers are separated into two
140: files to minimize the time required to download for those wishing to work
141: with only one part of the tree. The two files are <tt>sys.tar.gz</tt>,
142: which contains the files used to create the kernel, and <tt>src.tar.gz</tt>
143: which contains all the other "userland" utilities.
144: In general, however, you will usually want both of them installed.
145: Assuming the downloaded files, <tt>src.tar.gz</tt> and
146: <tt>sys.tar.gz</tt> are in <tt>/usr</tt>:
1.224 nick 147:
1.22 niklas 148: <pre>
1.224 nick 149: # <b>cd /usr/src</b>
150: # <b>tar xzf ../sys.tar.gz</b>
1.225 nick 151: # <b>tar xzf ../src.tar.gz</b>
1.226 nick 152: # <b>cd /usr</b>
153: # <b>tar xzf XF4.tar.gz</b>
154: # <b>tar xzf ports.tar.gz</b>
1.22 niklas 155: </pre>
1.100 ericj 156:
157: <p>
1.249 nick 158: Not all people will wish to unpack all the file sets, but as the system
159: must be kept in sync, you will generally need to set up all trees.
1.226 nick 160:
161: <p>
1.249 nick 162: You can also just use cvs(1) to "<b>checkout</b>" the source repository
163: for you. This is discussed in the <a href="#using">next section</a>.
1.100 ericj 164:
165: <p>
1.249 nick 166: After this, <tt>/usr/src</tt> will be a nice checkout area where all
167: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cvs&sektion=1&format=html">
168: cvs(1)</a> commands will work properly.
1.100 ericj 169:
1.249 nick 170: <h3><a name="using"><font color="#0000e0">Using CVS to get and update your
171: source tree</font></a></h3>
1.100 ericj 172:
173: <p>
1.249 nick 174: CVS was designed to be a simple way to retrieve and update your sources.
175: You must first decide whether you want to track <i>-current</i> or a
176: <a href="stable.html">patch branch</a>.
177: The current tree has all of the up to the minute changes,
178: whereas a patch branch contains a formal release plus the patches
179: from the <a href="errata.html">errata</a> and lesser issues already applied.
180: For more information on these "flavors" of OpenBSD, see
181: <a href="faq/faq5.html#Flavors">here</a>.
182:
183: <p>Once you have decided which tree to follow, you must choose which Anonymous
184: CVS server you are going to use. A list of these servers is
185: <a href="#CVSROOT">below</a>.
186:
187: <p>
188: Once you have chosen which <a href="#CVSROOT">Anonymous CVS Server</a> you will
189: use, you can start using cvs. For those of you
190: who have CDs you can start with the CVS checkout that is on the CD by using
191: the method <a href="#starting">above</a> to get the sources onto your system.
192: If you don't have a CD handy, use the method below to checkout the sources.
193: This method puts the OpenBSD source tree into <i>/usr/src</i>.
1.100 ericj 194:
1.135 naddy 195: <pre>
196: # <b>cd /usr; cvs checkout -P src</b>
197: </pre>
1.99 ericj 198:
1.1 deraadt 199: <p>
1.249 nick 200: The above will checkout the <i>current</i> source tree. Many of you will
201: only want the patch branch sources. To checkout a patch branch, you must
202: specify a tag along with your command. Example:
1.1 deraadt 203:
1.135 naddy 204: <pre>
1.257 steven 205: # <b>cd /usr; cvs checkout -P -rOPENBSD_4_0 src</b>
1.135 naddy 206: </pre>
1.1 deraadt 207: <p>
1.257 steven 208: Or OPENBSD_3_9 for 3.9, etc.
1.100 ericj 209:
1.257 steven 210: <p> The OPENBSD_4_0 tag contains the release sources and
1.249 nick 211: errata already applied.
