Story #5067

Updated by dkliban@redhat.com almost 5 years ago

h3. Motivation 

 Dependencies for content can be present in multiple repositories. 
 The problem existed before but became more apparent with the introduction of modularity. 
 Sometimes repositories are split into 2, modular and non-modular, instead of being a hybrid repo. 
 For such cases it's essential to have an ability to specify multiple pairs of source/target repositories, otherwise dependency soling can't be performed correctly. 

 h4. Suggestion 

 Modify the unit association Provide new API endpoint[0] endpoint where it would be possible to accept a new additional argument. 

 *POST* to */pulp/api/v2/repositories/<destination_repo_id>/actions/associate/* will take an optional parameter called *additional_repos*. This will be a dictionary where each key is a specify multiple pairs of source repository id and the value is the destination repository id. The additional target repositories would then also be used during the recursive copy only. The dispatched task will need and a criteria for what to lock on all the destination repositories.  

 h4. Sample request: 


 <pre> 
 { 
   'source_repo_id' : 'pulp-f17', 
   'criteria': { 
     'type_ids' : ['rpm'], 
     'filters' : { 
       'unit' : { 
         '$and': [{'name': {'$regex': 'p.*'}}, {'version': {'$gt': '1.0'}}] 
       } 
     } 
   }, 
  'additional_repos': {'source2': 'destination2', 'source3': 'destination3'}, 
  'override_config': { 
    'recursive': true 
   }, 
 } 

 </pre> 

 *The response format will stay the same as it is now:*
