When multipath is enabled, and the 3PAR driver is configured
to export a VLUN over N iSCSI IP(ports), we now use the same
LUN ID for each iSCSI IP export. Previously, when we would
export a volume over N iSCSI ports, we would get a new LUN ID
for each iSCSI port.
Cinder v2 API allows creating a volume with a quoted (single or double
quotes or even unbalanced number of quotes) display name. But when we
try to get info for such volume, we end up getting an error message
saying that no volume with such a name or ID exists. This error is due
to the inadvertent stripping of quotes from the filter in the api layer.
The api call eventually comes to check_volume_filters() in
cinder/volume/api.py. The invocation of ast.literal_eval() inside this
method strips the quotes for certain quoted strings leading to this
incorrect filtering. ast.literal_eval() is used to convert string
representations into python objects which are then used to frame the
SQL queries in the db layer. For example, the string "[1,2]" for a
filter (not the display name filter) gets converted to a list object
and results in an "IN" operation being emitted in the SQL query as
opposed to an exact match.
When display_name does not contain any quotes or contains an unbalanced
number of quotes, then ast.literal_eval() throws (just like the Python
interpreter would throw for an unquoted string literal or one with
unbalanced number of quotes). We handle this by ignoring the exception
and using the raw input value as the filter and moving on. For string
containing balanced number of quotes, such as, '"foo"',
ast.literal_eval() succeeds and returns the input with the surrounding
quotes stripped (just like how the python interpreter strips quotes
from a string literal to initialize a string var's value in memory).
To always use the raw user input string as the filter value, we can
either not pass string inputs to ast.literal_eval() or encode the
string using encode("string-escape") so that we get the original string
back after passing through ast.literal_eval(). We choose the former as
the latter buys us nothing.

Fix test_create_volume_flow test issue
One of the tests in
cinder/tests/unit/volume/flows/test_create_volume_flow.py incorrectly
mocks time.time function which means that when there's a call to
time.time() it will raise an error because real time function doesn't
expect any arguments but the mock method does expect self as an

For some reason time.time function does not get called on every test

This patch fixes this by binding the mock method to the current self

This patch updates replication to match the v2.1 spec. This makes it
so an entire backend can be replicated, and upon failover, all

Both sync and periodic replication modes are supported. Each
replication_device entry should have a replication_mode value set
to sync|periodic.
A volume type extra_spec value of replication:mode
should also be set. If replication:mode is periodic,
replication:sync_period should be set as well. Which replication_device
entry(s) are used is determined by the value of replication:mode set for
each volume type. NOTE: If no extra_specs are provided, periodic mode is
defaulted with a replication period of 900 seconds.

Update Pure replication to cheesecake
Migration to cheesecake replication. This basically

It also completes the transition to allow swapping the underlying array

array. Now it is all driver operations.
This also switches the target_device_id to backend_id in the config for

Fixed logging for oslo versioned objects
Earlier, when we wanted to log a message with an object as a parameter,
obj_attr_is_set method used to check name parameter, which was a wrong
approach. The reason was, that the oslo logger, when received a
versioned object as a resource parameter, is trying to get the 'name'
parameter, which is a property, so the obj_attr_is_set method will
return False and the logger will try to get the 'type' parameter, which
does not exist in some versioned objects (please take a look at
oslo.logging code [1]).
Now, when the parameter's name is present in obj_extra_fields
dict, we avoid calling obj_attr_is_set and simply get() it.
The other cause was a difference between fields names: size (in volume
object) and volume_size (in snapshot object), and inproper condition
statement in lvm driver.

Fix sshpool.remove code
Currently, sshpool.remove function under cinder/ssh_utils.py
is broken. The function tries to locate the passed in
sshclient object inside sshpool.free_items.
However, since the sshclient object is set to “None” at the
beginning, it never finds the object and ends up decrementing
the current size, without actually removing the object.
Made the following changes to fix:
1. Removed reset to ‘None’ so that the attempt to locate object
goes through.
2. Fixed the code to use free_items.remove(ssh) to remove the ssh
object identified instead of free_items.pop(ssh)
3. Also updated the code to decrement current size only if a match
is found in free_items.
4. Added test case to test remove() of an ssh client that is in the
free_items
5. Added test case to test that remove code does not inadvertently
remove an object from the pool if no match is found.

Add ability to failback for replication V2.1
Initially we had setup replication V2.1 (Cheesecake) to NOT
do fail-back at least in the initial version.
It turns out that fail-back in the Cinder code is rather easy,
we just enable calling failover-host on a host that's already
failed-over and use the *special* keyword of "default" as the
backend_id argument which signifies we want to switch back to
whatever is configured as the default in the cinder.conf file.
To do this we just add some logic that checks the secondary_backend_id
param in volume.manager:failover_host and set service fields
appropriately. Note that we're sending the call to the driver
first and giving it a chance to raise an exception if it can't
satisfy the request at the current time.
We also needed to modify the volume.api:failover_host to allow
failed-over as a valid transition state, and again update the
Service query to include disabled services.
It's up to drivers to figure out if they want to require some
extra admin steps and document exactly how this works. It's also
possible that during an initial failover that you might want to
return a status update for all volumes NOT replicated and mark
their volume-status to "error".
Expected behavior is depicted in the service output here:
