Adjust astakos to new holding design
Simplifications due to removal of quantity and merging capacity into holding.Also make sure that holders and resources are represented as strings inquotaholder calls.
Turn holding into a counter
The role of Holding is now only to keep track of usage againsta limit. There is no more exporting of resources and thus no needfor the stock counters.
Rename capacity to limit
New quota functions in astakos
Handle quotas as nested dictionaries indexed by:user uuid, source, resource name
Compute and show quotas by source
Adjust astakos code to the new nested dict structure of quotas.
Move quota-related code out of models.py
Intention is to collect all quota-related code to a single file.
Pass user.id in project join/leave operations
This is done for reasons of uniformity.
Sync to quotaholder by recomputing user quotas
On a user joining/leaving a project or on a project definition change,we used to compute quota diffs for affected users and add them upto existing values in quotaholder.
We now switch to recomputing all quotas for affected users and resetting...
Merge Policy model into Holding
Since the removal of quantity, Policy was left with only one value:capacity. To simplify things, we directly include capacity in Holding.
This makes obsolete the following functions, which are removed:get_limits, set_limits, get_holding, set_holding.
Import resource from no source
Since quantity (initial supply) has been removed from Policy,there is no direct way to set the initial available resource,for example the total available VMs for holding cyclades.
This is now achieved by issuing (and accepting) a commission...
