In the NVP plugin, metadata processing performs several plugin operations
with the same context (and db session). The first operation might leave
persisted objects in the session instance which then conflict with objects
created in the second operation.

Use information from the dnsmasq hosts file to call dhcp_release
Certain situations can cause the DHCP agent's local cache to get out

LBaaS: handle NotFound exceptions in update_status callback
LBaaS agent may send update_status requests to server on objects
which were already deleted from db: this is due to creating and
deleting objects with a high rate (like tempest API tests do).
As a result errors and stacktraces appear in server and agent logs.
The proposed solution is to catch NotFound exceptions and print a warning.

Fix pip install failure due to missing nvp.ini file
It looks like sdist does not support symlinks, therefore
letting nvp.ini point to nsx.ini is not a good solution.
Since nvp.ini is going away, leave a copy for now, but

Fix race condition on ml2 delete and update port methods
Synchronize access to ports table when deleting and updating
a port. Otherwise concurrent update/delete request for the same port
may cause neutron server to throw an exception and return
'500 Internal server error' for such requests.
When the rename of quantum->neutron occurred here ee3fe4e8 it also renamed
the the table creation from quantum_nvp_port_mapping to
neutron_nvp_port_mapping. This went undetected for a long time because
when neutron-server starts up it pushes down the scheme for tables that
are not there so the table would be created.
Because of this the following migration 50e86cb2637a called
op.rename_table('neutron_nvp_port_mapping', 'neutron_nsx_port_mappings')
though the table name being used was quantum_nvp_port_mapping. Because of this
the quantum_id->nvp_id mapping was never migrated over to the new table and
you would be left with a quantum_nvp_port_mapping table hanging around.
In addition, the downgrade would rename the table to neutron_nvp_port_mapping
instead of quantum_nvp_port_mapping. This patch addresses this issues.

transactional (as they involve non synchronized DB

Start of new developer documentation
There is currently no useful developer-focused documentation in-tree
for Neutron. There are a smattering of useful documents on the
OpenStack wiki, however, there isn't a good organization to this
information, nor is there a condensed developer focus to a lot of it.
Some of the wiki pages are more proposals for features or bug fixes,
and there is a need for architecture, design, and code walk-through
documentation for Neutron to help with new (and existing) contribution.
This patch begins the process of adding developer documentation to Neutron.
It updates the main developer reference index.rst to pull in-line with what
Nova is doing, leaving some todo references for future patches. It also
adds a development.environment tutorial that is up-to-date with current
Neutron development, using tox/testr processes for running unit tests and
including a number of references to external wiki pages that have
instructions for using DevStack for OpenStack contribution/testing.
The next series of patches will add automodule documentation to the
developer reference for some of the major modules in Neutron.
