AnalysisRequestDigester returns stale data

[ramonski]

Steps to reproduce

• Publish an AR from "Domain A" and afterwards from "Domain B", e.g. localhost/127.0.0.1
• Change the Lab information

Current behavior

• URLs stick to Domain A
• Lab data, e.g. the Name are not updated

Expected behavior

All data is equal to the real data in the system

 Another issue with the AnalysisRequestDigester cache. It stores virtual URLs which will have a negative effect when someone browses the LIMS under different virtual host names. E.g. on my dev machine which runs on http://localhost:6100 The report print want’s to access the images via http://localhost:8888 which comes from the productive machine.
So I cannot test with the copied productive Database correctly at the moment.

A better approach for caching would probably be to use plone.memoize.volatile with the store_on_context storage.

However, we should focus on how to avoid the need for caching at all. This is only possible if we avoid preparing data that might be eventually needed by someone somewhen and rather prepare the data only then when the user requests for it.

I would like to remove that digester completely and look for a better approach to tune the performance. IMO that digester is also responsible for the "Analyses without acquisition chain", because persistent objects are hold in a plain dictionary in there.

Closing in favor of the upcoming senaite.publisher replacement, which will replace the old report engine in one of the next versions
