Thoughts on SubVersion server setup with WebDAV + auto versioning

noreply@blogger.com (klausolino) — Thu, 02 Nov 2006 12:19:00 +0000

This is a quick HOWTO log from setting up SubVersion, Apache WebDAV, and auto versioning.

Download Apache from http://www.apache.org.
Download SubVersion from http://subversion.tigris.org.

Assuming Windows 2000 with Apache 2.0.54 + SubVersion 1.4.0.

Install Apache, e. g. in "C:\Program Files\Apache Group\Apache2\".
Unpack svn, e. g. in "C:\Program Files\Subversion\".
Chose repository server location, e. g. in "C:\dat\svn\".

Documentation for svnserve:
http://svnbook.red-bean.com/en/1.1/ch06s03.html

Start svn server:

svnserve -d -r C:\dat\svn

Create repository:

mkdir C:\dat\svn
svnadmin create C:\dat\svn

Check:

svn status

Setup shell:

set SVN_EDITOR=notepad

Think of project names (e. g. www, doc, ods) as top-level directories.
Beneath, create directories for trunk, tags, branches.

Tag files about to be versioned with these keywords in the headers:

$Date$
$Revision$
$Author$
$URL$

Alternatively, use $Id$.

For fixed width (e. g. in binary office documents), use $Date:: $ syntax.

Test importing files from current directory into the repository -- will add current directory to the repository root:

svn import . svn://127.0.0.1

Works only if user authentication has not been setup. Otherwise:

cd .../projectname
svn --username klaus --password secret import . svn://127.0.0.1/projectname/trunk

This imports the current directory at the specified point in the repository.

Create .svn association in respective directories:

svn --username klaus --password secret checkout projectname/trunk

Modify an existent file and test via an svn commit:

notepad file.txt
svn commit

Bulk set properties via:

svn propset svn:keywords "Date Revision Author URL"

Enforce access restrictions (klaus / secret):

notepad C:\dat\svn\conf\svnserve.conf

[general]
anon-access = none
auth-access = write
password-db = passwd
authz-db = authz
realm = Klaus' Repository

notepad authz

[groups]
www.k-hi.net = klaus

[/]
klaus = rw
* =

[repository:/]
klaus = rw
* =

[/www]
klaus = rw
* =

todo: add Carl-Martin, Christian, Renate, ...

notepad C:\dat\svn\conf\passwd

[users]
klaus = secret

Again, test import with username / password protection:

cd .../projectname
svn import --username klaus --password secret . svn://127.0.0.1/projectname/trunk

(--no-auth-cache would prevent caching the credentials locally.)

svn log --username klaus --password secret svn://127.0.0.1
svn list --username klaus --password secret svn://127.0.0.1

-- then do 1st checkout

svn checkout --username klaus --password secret svn://127.0.0.1/projectname/trunk

dir /a

This yields a hidden .svn directory!

Set up the shared object files with Apache:

copy "c:\Program Files\Subversion\bin\*.so" "c:\Program Files\Apache Group\Apache2\modules\*.*"

mod_authz_svn.so
mod_dav_svn.so

Modify httpd.conf:

LoadModule dav_svn_module mod_dav_svn.so
LoadModule authz_svn_module mod_authz_svn.so

Or point over to SubVersion:

LoadModule dav_svn_module "C:/Program Files/Subversion/bin/mod_dav_svn.so"
LoadModule authz_svn_module "C:/Program Files/Subversion/bin/mod_authz_svn.so"

tail -f httpd-access.log

"C:\Program Files\Apache Group\Apache2\bin\htpasswd.exe" -c htpasswd klaus

httpd.conf:
<VirtualHost _default_:81>
        ServerAdmin blub@blubbel.nospam.com
        DocumentRoot "C:/dat/www/blubbel.com/pub"
        ErrorLog logs/blubbel.com-error.log
        TransferLog logs/blubbel.com-access.log

RewriteEngine on

        <Location /svn>
                Dav svn
                AuthType Basic
                AuthName "Auth Required"
                AuthUserFile "C:\Program Files\Apache Group\Apache2\conf\htpasswd"
                Require valid-user
                SVNPath /dat/svn
                SVNAutoversioning on
                AuthzSVNAccessFile /dat/svn/conf/authz
        </Location>
</VirtualHost>

http://192.168.1.103:81/svn/
(klaus / secret)

For example:

P:\>"C:\Program Files\Subversion\bin\svn" log svn://127.0.0.1

And a bit of brainstorming:

http://www.ics.uci.edu/~webdav/
"DAV Explorer is a WebDAV, DeltaV and ACL client application that uses the WebDAV, DeltaV and ACL protocols ..."

Get Version Tree HTTP 501error

Guessing and rewriting:

Does not work!

Copyright goes Google

noreply@blogger.com (klausolino) — Tue, 10 Oct 2006 21:03:00 +0000

Some bullets:

- Google buys YouTube for 1.65 billion USD.
- Google is worth 100+ billion USD; it is stable enough to not be sued
to death.
- Google does have experience in copyright issues - e. g. from caching
web pages, digitizing books or image search.
- Google does have algorithmical competence to solve problems
automatically, i. e. without human intervention.
- As a side note, venture capitalist Sequoia Capital jumps from an 11.5
million USD investment up to 495 million USD share worth within less
than 2 years.
- In the future, algorithms and processes have to make ground: Like
AdSense (extracting the essential from the http referrers), there has to
be a way of tagging + voting for digital content so that it allows to
donate to their creators, along with a statistical method to evaluate
their price or share and dynamic "importantness". This will blow up
existent methods of distributing content that already is on the decline.
- Google will redefine copyright in a very social way.
- It will also redefine how emotions are perceived globally.
- This yields fine-grained democracy.

Bike Lanes are Not Bike Lanes

noreply@blogger.com (klausolino) — Tue, 19 Sep 2006 19:48:00 +0000

TV commercials are about what things are not to make one believe they are:

Automobiles and washing powder are not environmentally friendly.
Dish liquid is not meant for bathing your hands in.
Fast food might not really be part of a healthy diet.
Insurances do not really like to pay.

Now, besides that, some things in daily use are also not what they seem to be.
Like bike lanes.

Topologically, most cannot be used beyond a certain speed, as they are too curvy or too deteriorated, or they are too slippery during rain.
In city centers, they are parked on with or crossed by cars, and people keep stepping in unexpectedly.
Some are under construction, or getting on or off them without losing too much velocity is a difficult achievement.

Nor are bikes what they seem to be. Bikes are:

Faster than they were, as they are more lightweigt, have better transmission and better suspension.
Less respected and perceived in an aggressive society and a visually overloaded environment.

I would like to see bikes to have similar rights than have cars. -- Take Spanish national roads as an example: They have a separate lane besides the main ones - intended for smaller and slower cars to move out, but also perfectly suited for cyclists that quickly want to make distance. -- More uniformity, simplicity and space would add to more safety.

Hello world!

noreply@blogger.com (klausolino) — Sat, 16 Sep 2006 23:13:00 +0000

Hello world,

welcome to my 1st blog!

Today -- I cycled 2 x 22 km on the mountain bike across national roads to Bornbruch lake south of Frankfurt (N49.970021 E8.596652) + had a little tanni + swimmi-swimmi on the very last summer day.

Then rode into downtown Frankfurt on the Yamaha, had "Pollo Italiano" at Cafe Bar Celona.

News headline is "pope insults the prophet".

Ali Bardakoglu on http://www.spiegel.de/politik/ausland/0,1518,437396,00.html (translated): "Moslems have to learn to express their reactions reasonably, to think and to act rationally. In principle, emotional and violent reactions are wrong. Violence has to be replaced by the word." (Die Muslime müssen lernen, ihre Reaktionen vernünftig auszudrücken, rational zu denken und zu handeln. Emotionale und gewalttätige Reaktionen sind grundsätzlich falsch. Die Gewalt muss durch das Wort ersetzt werden.)

I wish to believe in the freedom of press and in creative disrespect, based on rationality, as well as a scientific, documented approach in resolving issues.

It might however be that indoctrination, mysticism + hate against people + societies outside one own's overseeable environment is plainly stronger -- purely because it is a simpler concept -- less rational, more physical + biological.

Good night!

Klaus
