[Registry-dev] Retrieving a Resource after deletion without adding it again

Hi devs,

I have a scenario in the Mashup Server, where a Mashup will get
redeployed by simply doing a unix style 'touch' of the js file or
editing and saving the js file. At both times the service will be
undeployed and deployed back.

Currently we delete the Mashup from the Registry at undeployment and
'put' it back again at deployment. However, this adds un-necessary
records to the registry database by means of versions when the delta
between two deployments is '0'.

I worked out an MD5 based verification mechanism on the Mashup side to
make sure there is a delta and do a 'put' only if required. But the
problem I have right now is that there is no way to 'rollback' a
deletion in such a scenario. If there is such a thing, I can simply
rollback the deletion on the resource, when there is no delta in the js
file between two consecutive deployments.

Am I missing something here?

thanks,
Tyrell
