Enable and disable Shindig caching

Shindig implements a complex caching hierarchy including referred external resources, locale messages, gadget specification files, etc.
During development phase, the developers want to disable caching to make modifications take effect immediately.

• Build-Time Solution
  It is according to this post https://studio.atlassian.com/browse/AG-145.
  Download source code tree and build the war file using command “mvn –Pdebug package”
  
• Run-time solution
  HttpCache: caches http request sent out from shindig server. During gadget rendering, this is controlled by “nocache” parameter. So when you render a gadget, add parameter ‘nocache’ with value 1.
  I don’t know how to do it at server side.

Transition from _IG_* APIs to gadgets.* APIs

iGoogle announced that legacy gadget APIs (_IG_*) are deprecated:

Migration guide:

It would be great if there is a migration tool that automate the process.

Deploy standalone shindig on Quarry and an OAuth gadget demo

I got a virtual machine which I can log in as root. The virtual machine is pretty clean without any more packages besides CentOS.
I installed vim using yum install vim-enhanced. I also installed jdk1.5 and maven2.

Then I checked out the source code from shindig svn trunk. See instructions here http://incubator.apache.org/shindig/#tab-building.
Unfortunately, the test failed when I compiled and installed shindig. This kind of things always happens because of instability of trunk code. So I copied my previous checkout of shindig code which worked well from another machine. Then the compilation and installation succeeded.

OAuth gadget demo to retrieve google contact list

Now the sample demo is here:
http://gw11.quarry.iu.teragrid.org:9999/gadgets/files/samplecontainer/samplecontainer.html

Set field "Displaying gadget" to http://156.56.104.196:8888/oauth/gadgets/os_gadget.xml, Uncheck "use cache".
Click button "reset all". If everything works fine, you would see following in main panel:

Clieck "Personalize this gadget", a popup window would appear which prompts you to login to your google account. Then you can choose grant or deny the access request. If you grant the request, the popup window would be closed automatically, and the main panel would be populated with your google contact list.
