Pulp

I discovered this bug while writing the pulp_example plugin. The sync code that could demonstrate this problem has not been merged (yet). HOwever, the issue can be demonstrated by adding the following diff to Pulp.

Assuming that pulp 3 is running on localhost:1234, you can create a repository:

http POST http://localhost:1234/api/v3/repositories/ name=mycoolrepo notes:={} scratchpad:={}

Add a file importer:

http POST http://localhost:1234/api/v3/repositories/mycoolrepo/importers/file/ name=mycoolimporter download_policy='immediate' repository='http://localhost:1234/api/v3/repositories/mycoolrepo/'

Modify the importer:

[vagrant@pulp3 pulp]$ http PATCH http://localhost:1234/api/v3/repositories/mycoolrepo/importers/file/mycoolimporter/ download_policy='on_demand'
HTTP/1.0 202 Accepted
Allow: GET, PUT, PATCH, DELETE, HEAD, OPTIONS
Content-Length: 135
Content-Type: application/json
Date: Thu, 10 Aug 2017 15:37:42 GMT
Server: WSGIServer/0.2 CPython/3.5.3

    {
        "_href": "http://localhost:1234/api/v3/tasks/36ee48dc-0a41-42b3-bd99-b4f222cbd5b9/",
        "task_id": "36ee48dc-0a41-42b3-bd99-b4f222cbd5b9"
    }
]

The last command returned a task id and a URL for that task. A GET request of that URL returns the task.

The task should include the progress report that was generated. However, it does not. The progress report does exist in the database though:

[vagrant@pulp3 pulp]$ psql --u pulp
psql (9.5.7)
Type "help" for help.

pulp=# select * from pulp_app_progressreport ;
