Synnefo

• Unit tests are greatly simplified
• All unit tests are using fixtures

• Add db/fixtures/db_test_data.json fixture (data for testing)

• FlavorTestCase now works correctly with the fixtures

• Removed initial_data JSON fixture
• Fixtures are now loaded on unittesting as intended
• Modified CreditAllocatorTestCase to load fixtures

Added comment in FlavorCostHistory.find_cost(), also made a minor optimisation

Initial Disk Management API (DM API) implementation

The DM API is accessible under api/v1.0grnet1/ and
it extends the Rackspace Cloud Servers v1.0 API
for the use of Disks. Notable changes:

• Added the "Disk" model in db/models.py
• Added the "DiskHandler" in api/handlers.py...

now Flavor._update_costs uses hasattr

fix bug in CreditAllocatorTestCase (bad data initialisation)

AccountingLog test is finished; most charger-related operations are ready and tested

VM owner is derived from the Image

Flavor.get_price_list() should query with filter, not get

remove obsolete tests; introduce various corrections/additions in models

added violations concept

simplified SynnefoUser a little; remove _total_hours

Make ZMQ thread in db_controller stoppable.

Make db_controller run all 0mq operations in a separate StoppableThread
with a stop() method. The main thread calls it, then publishes on an in-proc
PUB socket to interrupt any zmq_recv() call and join the thread when cleaning...

added get_vmid on Image model to return the first VMs id, if any. This was the serverid variable

updated initial data to test credit allocator testcase

• minor changes in models and tests (db)

Private fields in VM model, updated fixtures

Updated names of fields pertaining to VM state in VirtualMachine model,
updated fixtures.

database.sqlite can be removed, use:

rm database.sqlite; python manage.py syncdb

to recreate it from fixtures.

Use zmq_recv() in dedicated thread in db_controller.

It seems Python can only do signal processing in the main thread.
If the main thread calls zmq_recv(), no exceptions get raised
when a SIGINT is received for example.

WIP:
This moves the zmq_recv() to a separate thread, while the main...

Fix path issue.

Major fixes trying to integrate everything.

• db/db_controller.py: Listens on 0mq, receives notifications from Ganeti, updates
  VM state in database calling methods of the VirtualMachine model.
• Extended the VirtualMachine model:
  start_action() is to be called before submitting requests to Ganeti....

added User ForeignKey on Image

• Charger now works properly

Add charge_users command

Added command to invoke credit allocation for users

rename dbcontrol and charger into proper python name

Add test case about the virtual machine model (only data are generated so far).

• Enforcing PEP-8 in models.py

• Add tests for Flavor model
• cost_active and cost_inactive are now returned correctly

• Added test for credit allocator

• Messing with the Flavor and FlavorCostHistory; define two new properties to easily obtain active and inactive costs

removed id_from_instance function from the VirtualMachine model and put it back since it will be needed as a global function
to be imported by handlers and not as a staticmethod of the VM model.

• Add staticmethod decorator/annotation in id_from_instance_name

• Add FlavorCostHistory
• Remove cost_active, cost_inactive from Flavor (Charger is broken)

Implement init_publisher method

Work on DBController

Added is almost complete

Refactored CreditAllocator and Introduced main

Minor fixes to verbose_name fields.

verbose_name fields must be in singular, per
http://docs.djangoproject.com/en/dev/ref/models/options/.
verbose_name_plural can be used if a plural form is needed.

Playing with tabs and spaces

Minor corrections in CreditAllocator and Models

a few changes regarding the VirtualMachines id and ganeti id.

• on api/handlers.py : VirtualMachineName function removed (no need to be on the handlers)

• settings.py.dist: added GANETI_PREFIX_ID

• db/models.py: added id_from_instance_name function and property ganeti_id on VM models . These are needed to get the Django id...

added Image model and updated admin.py to include it as well

• Updated models for db

• fix models import in db scripts

• Rename aquarium -> db
• Add Virtual Machine States into vocabs.py

Renamed User -> OceanUser

Fix several errors in db.models

Among other things: * PEP-8 styling conventions * Remove unnecessary primary keys (Django handles those) * Remove ugly column name prefixes * Use singular for class names * Replace the buggy double-PKs with a unique_together...
