22: Anonymous CVS is a method of keeping your local copy of the OpenBSD source
23: tree up to date with respect to changes made to current OpenBSD sources.
1.99 ! ericj 24: </p>
! 25:
1.14 downsj 26: <p>
1.15 grr 27: The major advantage of Anonymous CVS over other source code update
28: techniques is that it works directly against a central source code
29: repository or mirror. This means that you have the full set of CVS
30: commands available to control merging and updating your changes with
31: other source changes and for performing diff's, change histories
32: and other queries against the central repository.
1.99 ! ericj 33: </p>

1.36 deraadt 35: <p>
1.99 ! ericj 36: The OpenBSD Project currently has three main source repositories:
! 37: </p>
! 38:
! 39: <ul>
! 40: <li><b>src</b> - Houses all source code for the OpenBSD Operating System.
! 41: <li><b>ports</b> - Houses the <a href="./ports.html">OpenBSD Ports</a>.
! 42: <li><b>www</b> - Houses all OpenBSD web pages. (Including this one).
! 43: </ul>

! 45: <h3><font color=#0000e0>CVS:</font></h3>
! 46:
1.36 deraadt 47: <p>
48: <a href=why-cvs.html>
49: CVS is the source code control system used to manage the OpenBSD source tree.</a>
1.16 deraadt 50: It implements a central repository for all officially released source code
1.15 grr 51: and changes, while permitting developers to maintain local copies of the
1.99 ! ericj 52: source code with their working changes. Developers with "<b>write access</b>"
1.15 grr 53: can commit changes directly to the OpenBSD source tree, while "Anonymous
1.99 ! ericj 54: CVS" users have "<b>read access</b>" and can keep their local copies of the source
1.15 grr 55: up to date and issue queries against the central depository.
1.99 ! ericj 56: </p>
! 57:
1.15 grr 58: <p>
1.22 niklas 59: The major strength of CVS is that it has the ability to perform intelligent
1.15 grr 60: merges of changes to the central repository with changes that you make to
61: your local copy. This means that if you make a change to a module and
62: perform an update, your changes are not "blown away", rather CVS makes
63: best efforts to merge the changes made to the central sources with changes
64: you've made to your local copy.
1.99 ! ericj 65: </p>
! 66:
1.15 grr 67: <p>
68: In the event that the changes can't be completely merged, CVS provides a
69: "soft fallback", in terms of providing you with annotated changes to your
1.39 todd 70: local copy, preserving an unmodified copy of your version and continuing
1.15 grr 71: to update any other source modules you requested.
1.99 ! ericj 72: </p>
! 73:
1.22 niklas 74: <p>
1.99 ! ericj 75: People who own an OpenBSD CD may have seen the <i>CVS/</i> dirs on it.
! 76: Actually there is a reason, the CD has a checkout of the OpenBSD <b>src</b> module
1.95 millert 77: usable to continue updating from. Using this tree will result in a much
1.23 mickey 78: faster initial CVS update than a fresh checkout of the full OpenBSD
79: source tree. There are two ways of using the CD:
1.99 ! ericj 80: </p>
! 81:
1.23 mickey 82: <ul>
1.99 ! ericj 83: <li>To copy the CVS tree from the CD to <i>/usr/src</i> (assuming the CD is mounted on /mnt):
1.22 niklas 84: <pre>
1.99 ! ericj 85: # <b>cd /mnt; pax -rw CVS Makefile [a-z]* /usr/src</b>
1.22 niklas 86: </pre>
1.99 ! ericj 87: <li>Use a union mount with the CD below a writable directory. (This can be used when only compiling from the tree.)
1.22 niklas 88: <pre>
1.99 ! ericj 89: # <b>mount -t union -o -b /mnt /usr/src</b>
1.22 niklas 90: </pre>
1.23 mickey 91: </ul>
1.99 ! ericj 92: After this, <i>/usr/src</i> will be a nice checkout area where all <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cvs&sektion=1&format=html">cvs(1)</a> commands will work OK.

1.39 todd 120: To summarize, the real strength of using Anonymous CVS is that it is
1.15 grr 121: a "tolerant" source code control system - it <strong>respects</strong>
122: changes that you have made to your local sources and makes <strong>
123: "best efforts"</strong> to update your entire source tree, rather than
124: leaving you a list of arcane problems that have to be resolved before
125: continuing.

1.1 deraadt 128: <p>
129: The latest version of CVS is available at
1.47 pauls 130: <a href=http://download.cyclic.com/pub/>Cyclic</a>.
1.1 deraadt 131: Versions earlier than 1.6 are not recommended, and may not work.
132: If you already have OpenBSD installed, CVS is included.
133:
134: <p>
135: There are two levels of source tree access:
136:
137: <dl>
138: <dt><strong>Read-write access for developers:</strong>
139: <dd>Developers who need to commit changes to the source tree must have
140: an account on the OpenBSD machines. Getting this access will be a
141: natural result of working on the sources with other OpenBSD developers.
142: If someone does some good work and shows they can work with the team,
143: they will get an account.
144: </dl>
145:
146: <dl>
147: <dt><strong>Read-only access for everyone:</strong>
148: <dd>Anyone can access the read-only CVS repositories. These copies
149: of the read-write CVS repository are mirrored often. To use one,
150: set your <strong>CVSROOT</strong> environment variable to one of

311: described in the Export Control list of Canada</a>
312: is legal to export crypto software from Canada to the world.

1.39 todd 384: Everytime you ran this it would synchronize your /usr/src tree. It would
1.1 deraadt 385: not destroy any of your local changes, rather it would attempt to merge
386: changes in. If you use obj directories (not obj symbolic links) you may
387: wish to append "-I obj" to the cvs command line, this will keep cvs from
388: spitting out a warning about all the obj directories it is going to
389: encounter which are not in the repository.

440: <p>
1.12 grr 441: <strong>Warning:</strong>
442: When using cvs you should take care that your current directory is either
443: the root of the tree you're referencing or in a separate place such as /tmp.
444: Some commands such as "get" can create an arbitrary sub-tree in the current
445: directory, and a subsequent update will recursively flesh out this sub-tree.
446:
447: <p>
1.1 deraadt 448: The anoncvs service gives fledgling developers a chance to learn CVS
449: operation and get thoroughly involved in the development process
450: before getting "commit" access -- as a result of showing useful
451: skills and high quality results they will naturally later be given
452: developer access. As well, people providing patches can create
453: their "diff"s relative to the CVS tree, which will ease integration.

455: <p>
1.15 grr 456: <strong>Anoncvs: rsh vs. ssh</strong>
1.12 grr 457: <br>
458: By default, the CVS client uses rsh to talk to the CVS server. Many
1.39 todd 459: of the CVS sites no longer support rsh for security reasons or a local
1.12 grr 460: problem like a firewall or imperfect protocol emulator such as slirp
461: may prevent you from using rsh.
1.97 deraadt 462: The alternative is a to use a "secure shell" connection using either
463: <a href=http://www.openssh.com>OpenSSH (*FREE*)</a> or
464: <a href=http://www.cs.hut.fi/ssh/>ssh (non-commercial and commercial)</a>.
1.68 wvdputte 465:
466: <p>
1.97 deraadt 467: The OpenBSD anoncvs repositries support the SSH1 protocol, not the SSH2
468: protocol due to the use of a "strict non-commercial use licensing policy".
1.28 beck 469:
1.75 millert 470: <p>
471: Once ssh is installed, one sets the environment variable
1.28 beck 472: <strong>CVS_RSH</strong> to point to ssh (typically
473: <strong>/usr/local/bin/ssh</strong>). If your local site prevents you
474: from connecting out to port 22 (which ssh defaults to using) use port
475: 2022.
1.1 deraadt 476:
477: <p>
478: Do not be tempted to turn on compression since CVS already compresses.
479: Use something like the following in your <strong>$HOME/.ssh/config</strong>
1.10 millert 480: file. Note that not all anoncvs servers allow ssh connections on
1.21 millert 481: port 2022. Also note that most anoncvs servers no longer accept
482: the <strong>none</strong> cipher as it is disabled in recent
483: versions of ssh for security reasons.

489: <p>
490: CVS is a little noisy starting up; to quiet it a bit you may want to

495:

1.8 deraadt 497: If you wish to change from one CVS server to another (say your normal one is
498: down, or for any other reason), the environment variable which will let you
499: do this is
500: <pre>
501: setenv CVS_IGNORE_REMOTE_ROOT
502: </pre>
1.72 millert 503: Note that you will also need to use the <strong>-d</strong> flag

1.65 matthieu 506: <p><strong>X11 Source tree</strong>
507: <br>
508: Anoncvs mirrors also carry the OpenBSD X11 source tree. You can adapt
509: the recipe above to update your X11 source tree from the second CD.
510: Either copy or use a union mount to get the X11 sources in /usr/X11:
511: <ul>
512: <li>copy the tree off it (assuming the 2nd CD is mounted on /mnt):
513: <pre>
514: <b>#</b> cd /mnt; cp -Rp X11 /usr
515: </pre>
516: <li>use a union mount with the CD below a writable directory.
517: <pre>
518: <b>#</b> mount -t union -o -b /mnt/X11 /usr/X11
519: </pre>
520: </ul>
521: After this, /usr/X11 will be ready to be used by cvs. You can for
522: example update it to -current source (assuming you've already set
523: the <b>CVSROOT</b> environment variable):
524: <pre>
525: <b>#</b> cd /usr/X11
526: <b>#</b> cvs -q update -PAd
527: </pre>

529: <p><strong>Setting up a new anoncvs mirror</strong>
530: <br>
1.1 deraadt 531: If you wish to be a new anoncvs mirror site, please contact the anoncvs
532: <a href=mailto:deraadt@theos.com>maintainer</a>.
1.30 beck 533: Anoncvs mirrors require about 500MB of disk, and use up to 4MB of swap
1.1 deraadt 534: per anoncvs user (assuming the user does a large operation; while smaller
535: operations use fewer resources, anoncvs still makes much more of an
536: impact than ftp or sup). Such anoncvs machines should have excellent
537: network connectivity for the area they are expected to serve. A
538: <a href=anoncvs.shar>document</a>
539: which describes the setup of anoncvs servers is available.
540:
1.60 millert 541: <h3><font color=#0000e0>Final notes:</font></h3>
542: After upgrading your source tree, you should read the comments
543: at the top of <KBD>/usr/src/Makefile</KBD> before attemping
544: a build. Also, you should build a new kernel <strong>before</strong>
545: doing a <KBD>make build</KBD> if possible. In some cases it make be
546: necessary to rebuild and install the <KBD>config</KBD> utility before
547: you can build the kernel. If <KBD>config GENERIC</KBD> fails this
548: is probably the case.
549: <p>
550: It is important to note that upgrading from a release to the current tree
551: by rebuilding the sources can be rather difficult due to dependencies
552: that are often not obvious. Therefore, it is suggested that you first
553: install the latest snapshot before attemping a tree build from source.
