Wt

Try a C++ based Wt library for developing web applications.

On Ubuntu, use apt-get

> sudo apt-get install witty witty-dbg witty-dev witty-doc

(ref.http://www.webtoolkit.eu/wt/wiki/index.php/Installing_Wt_on_Ubuntu)

Try examples.

> mkdir ~/wt
> cd wt
> cmake -DWT_SOURCE_DIR=/usr/share/doc/witty-doc/ -DEXAMPLES_CONNECTOR="wt;wthttp" /usr/share/doc/witty-doc/examples

Oops, need to install cmake.

> sudo apt-get install cmake

Running cmake again created a directory ~/wt/wt-homepage and ~/wt/wtwithqt.

Oops, again. need to install libboost

> apt-get install libboost1.35-dev libboost1.35-dbg

Gee, a lot of files are dependant... 60.7MB download and 358MB disk space consumed

Well, done. Running cmake

> cmake -DWT_SOURCE_DIR=/usr/share/doc/witty-doc/ -DEXAMPLES_CONNECTOR="wt;wthttp" /usr/share/doc/witty-doc/examples

terminal output

> ~/wt$ cmake -DWT_SOURCE_DIR=/usr/share/doc/witty-doc/ -DEXAMPLES_CONNECTOR="wt;wthttp" /usr/share/doc/witty-doc/examples

Hmmm, some examples are skipped... i found on the mailing list for Wt, it's a bug. will need to build Wt from the current souce to run these skipped examples. Anyhow, see what's created

TT(Tokyo Tyrant) supports memcached and http interface as well.

If working locally, various utilty commands like tctmgr can be used to manipulate Tokyo Cabinet databases.

Tokyo Promenade 2

Found that promenade.css is not really working. maybe, it was because it's installed under /usr/lib/cgi-bin. reinstalled under /var/www1/blog. it works better. but, now i realize passwd.txt is exposed Changed the directory of passwd.txt and reflected it on promenade.tmpl. Following the manual gave me errors in writing to the database. i changed the ownership of all the files in promenade to www-data, and it worked.

OK, it works. But, where are the data? It's in promenade.tct, i guess. It's a Tokyo Cabinet database. How can i access it? Hmm, need to learn more on the database handling. Because my interest right now is to use the database, what i need may be Tokyo Tyrant, which gives me access to Tokyo Cabinet databases.

Installing Tokyo Cabinet and Tokyo Promenade

Started to install Tokyo Cabinet and Tokyo Promenade. Info is here (in Japanese). Planing to move this blog to Tokyo Promenade if I succeed.

Requirements for installation: Linux 2.4+, gcc, make, zlib, bzip2. Make sure they are installed. Fro zlib, do

> sudo apt-get install zlib1g

Download the source file:http://tokyocabinet.sourceforge.net/tokyocabinet-1.4.31.tar.gz. Untar

> sudo tar xzvf tokyocabinet-1.4.31.tar.gz
> cd tokyocabinet-1.4.31/

Configure

> ./configure

gave an error

configure: error: zlib.h is required

. Did

sudo apt-get install zlib1g-dev

Reran configure. Now

configure: error: bzlib.h is required

. Did

> sudo apt-get install libbz2-dev

. Dd

> make
> make check

Checking emits a lot of lines on the terminal screen, and takes some time. Feel even meticulous, but it's probably a good engineering practice to make sure everything works as it should. Need a coffee break After probably thousans of lines, got

#================================================================
# Checking completed.
#================================================================

Did

> sudo make install

Got

#================================================================
# Thanks for using Tokyo Cabinet.
#================================================================

OK

Now download TokyoPromenade here. See here for installation (in English). Untar

> sudo tar xzvf tokyopromenade-0.9.2.tar.gz

Did

> ./confiture
> make
> make check
> sudo make install

in seconds successfully. Create a base directory for CGI as

> sudo mkdir -p /usr/lib/cgi-bin/tokyopromenade

After setting up the Apache site file at /etc/apache2/sites-available/sitefile3, accessing here gave me this page

Simple and sufficient! I like it

OK. What next? See here, for the instructions (in Japanese). Well, it doesn't explain how to register a user When tried with guest without a pasword, login was successful. But, how ca I create a user? Alright, I found it in a blog article here. I.e., admin/nimda for administrator. The top page for admin is

Hitting the "users" there gets
