SOLVED: Save Hudson configs to Subversion. Automatically.

Wed, 13 Oct 2010 07:51:41 GMT

I decided to save Hudson configs to Subversion repository just in case something goes wrong with the server later and would need to restore all projects. A bit of googling first, found that there are plugins to to a backup of workplaces and configs. But why would I need to have them? I am on Solaris, so I can create the same by my own hands. Here are my requirements:

Backup should be a job within Hudson - since Hudson is a best cron you could find and I already have it
Backup should automatically discover added jobs and add then into Subversion - thus I will forget about it forever, no maintenance required

Simples! So I created a custom build job within Hudson, pointed it to a Subversion location, where I will store backups and backup shell script, which will gather all Hudson configs and deal with Subversion. I told Hudson that I don't want to create subfolder for a project within its workplace. Then I set to execute script this way: ${WORKPLACE}/hudsonbackup.sh Here is the script itself:

#!/bin/bash

SRC_FOLDER=${WORKSPACE}

SVN_PARAMS="--config-dir /.subversion/ --non-interactive --trust-server-cert --username f_tc_ci1 --password *"

SVN_COMMAND="/opt/csw/bin/svn"

JOBS=ls -al /.hudson/jobs/|grep -v job1|grep -v job2|awk ' NR>3 {print $9}'

CURR_FOLDER=pwd

echo "Copying Hudson configs"

cp /.hudson/*.xml ${SRC_FOLDER}

echo "Done."

cd ${SRC_FOLDER}

echo "Processing Hudson jobs"

for JOB in ${JOBS}

do echo "Processing ${JOB}" if [ ! -e ${JOB} ] then echo "New job. Creating folder and adding it to SVN" mkdir ${JOB} ${SVN_COMMAND} add ${SVN_PARAMS} ${JOB}
SVN_COMMENT="${SVN_COMMENT} Added ${JOB}" fi

echo "Saving ${JOB}/config.xml" if [ -e ${JOB}/.svn ] then if [ -e ${JOB}/config.xml ] then # config.xml already exist - don't need to add it to subversion cp /.hudson/jobs/${JOB}/config.xml ${JOB}/ else echo "New job - new config.xml" cp /.hudson/jobs/${JOB}/config.xml ${JOB}/ ${SVN_COMMAND} add ${SVN_PARAMS} ${JOB}/config.xml fi else echo "Problem creating and adding folder to Subversion" exit 1 fi done

echo "Job processing is done. Committing..."

${SVN_COMMAND} ci ${SVN_PARAMS} -m "Config saved by Hudson. ${SVN_COMMENT}"

echo "All done."

Note 1: My Subversion is on HTTPS server with the self-signed certificate, so I have to tell Subversion client to trust it explicitly. Its on line 4. On line 5 I constructed the path to Subversion client because Hudson executing shell scripts with quite limited PATH. Note 2: I need to ignore some jobs, so I added them on line 6. Also on this line I have hardcoded Hudson location ("/.hudson") - it needs to be changed if your Hudson somewhere else. After all that I set this job to execute daily. It works!

Faces component: Table with subtotals

Fri, 09 Mar 2007 08:44:11 GMT

I tried to search all over the web for a Java Faces component, which will do a simple thing: totals and subtotals. And I failed. It seems that whole web is about how much more AJAX you could put everywhere, not how more useful your product could be for average user.

It could be done through a facet tag, which is obvious.

I think about that as competitive advantage for myself. If nobody done it - I should do it and be recognised for it!

Microsoft Origami

Sat, 25 Feb 2006 09:50:51 GMT

Microsoft has opened a viral marketing site about something called Origami. It was discovered by Design Tastes Good, they sent an email to Scoble with questions and Scoble responded in his snobby manner "I know everything, but I can't say it to you". And not the hell broke loose.

Engadged posted the pictures of the future gadget, but denying the validity. Todd Bishop remembered the Bill Gates' WinHEC speech about new device, and Transmeta's announcement about some agreement with Microsoft.

I hope that Microsoft will create something really useful and with neat design. What I need in such device is:

It should be small. Preferably fits on one palm
It should have keyboard. Even if it has touch screen - I ltype much better, than scribble.
USB 2.0 connector/charger
Bluetooth and Wifi.
If it has IrDA - it's beam must be strong enough, so I can use gadget as remote control
No special (iTunes like) software required to connect to device

Keeping phone call records

Ramit Sethi writes about capturing and keeping a records of every calls to customer services and provides an Excel file to do that.

This is wonderful idea. I do some of the call notes in my Moleskine, but never though of having Excel of Word file for this purpose.
