CDS: Fix deleteSnapshots criteria in SnapshotManager

The SnapshotManager specifies a magic number 43200000 as the timestamp
for the criteria passed to deleteSnapshots. It's unclear where this
number came from but it prevents prior snapshots from getting deleted
as stored snapshot timestamps will be greater than this value (unless
one was created back in the 70's or 80's :)). Since the SnapshotManager
passes a valid upper bounds for the criteria's maxSequenceNr, I changed
it to pass Long.MAX_VALUE for the timestamp.

The ReplicationAndSnapshotsIntegrationTest actually verifies prior
snapshots were deleted by checking for size 1 when querying the
InMemorySnapshotStore. However this only passes b/c the

Tom Pantelis [Thu, 12 Nov 2015 08:47:27 +0000 (03:47 -0500)]
Bug 2187: Bootstrap EOS shard when no local shards configured

The intended workflow to initially form a cluster dynamically is to
change the role for a second node to say member-2. Since the initial
static shard config is bootstrapped to member-1, no local shards will be
created. However, the entity-ownership shard is special in that it is
intended to exist on every node.

The EOS will be boostrapped as follows:

For the EOS CreateShard message, all unique members for all shards are
obtained from the static shard config. It assumes the local member is
present in the config however in the above workflow it won't be. So on EOS
CreateShard, if the local member isn’t in the initial member list then
it will create the local shard with an empty peer list and
DisableElectionsRaftPolicy so it stays as follower. Also the shard will
be flagged as inactive in the ShardManager. A subsequent
AddShardReplica will be needed to make it active.

The other option is to not create EOS shard but there may be initial
candidate registrations which would be missed unless we add retry logic
in the service class. But the EOS shard already has retry logic so it
would be ideal to leverage it.

I also made changes to the AddShardReplica logic to handle an existing
local shard as will occur for the EOS shard:

 - remove the failure reply if local shard already exists
 - if the local shard exists and the primary shard is the local shard,
   do nothing and return AlreadyExistsException failure reply
 - otherwise send AddServer to the primary
 - on FindPrimary, if the local shard exists but is not active, do a
   remote find as if the local shard doesn't exist
 - on AddServer, if the new server is already in the peer list, the
   ALREADY_EXISTS status is returned. Return AlreadyExistsException
   failure reply
 - on AddServer failure, if the local shard was pre-existing don't
   remove it.

We still want to prevent an AddShardReplica request which one is already
in progress so I added a Set to track this.

I added an integration test for bootstrapping the EOS shard. It starts
with an inactive shard and registers a candidate, which gets queued
since there's no leader. It then issues AddShardReplica and verifies the
candidate gets registered with the leader.

To get this to work required some teaks in the RaftActor and Follower.
When the ShardManager clears the DisableElectionsRaftPolicy, the
RaftActor creates a new Follower instance however it loses the previous
leader Id. If the new server config hasn't been replicated yet then it
has no peers and immediately tries to start an election. Since it has no
peers it goes to Leader wih no followers creating a 2 leader situation.
To alleviate this I transferred the previous leader Id to the new
Follower instance to prevent the immediate election.

Eeven after that the test still didn't work b/c the leader was still not
in the EOS shard peer list so lookup of the leader address returned
null. So I changed getPeerAddress in the RaftActorContext to lookup in
the resolver if no peer info exists.

I also added more units for AddShardReplica to increase code coverage.

4 years agoBUG 4554 : Ownership is not cleared when all candidates are removed 32/29632/2
Moiz Raja [Fri, 6 Nov 2015 02:21:56 +0000 (18:21 -0800)]
BUG 4554 : Ownership is not cleared when all candidates are removed

When all candidates for an entity get unregistered at approximately
the same time it can create a situation where the owner for the
entity is not cleared. Consequently no entity ownership change is
raised where hasOwner is false even when there are no owners for
the entity.

This could be a problem for applications which do
some action when there are no candidates for an entity. The
openflow application for example relies on the disappearance of
all owners to actually remove a switch from inventory. Without
this event we have the situation that nodes hang around in inventory.

Problem Sequence
----------------

The sequence of events which leads to this problem are as follows.

Let's say member-1 owned entity-1 and there are 3 candidates for
entity-1 - member-1, member-2 and member-3. Now let's say due to
some event all candidates have to unregister. The data
transaformations will go like this.

delete member-1
delete member-2
delete member-3
delete member-1 succeeds so choose new owner - in this case member-2
make-owner member-2
delete member-2 succeeds - member-2 is not the current owner so do nothing
delete member-3 succeeds - member-3 is not the current owner so do nothing
make-owner member-2 succeeds. Now we have an owner for entity-1 even though we have not candidates

Solution
--------

The solution proposed in this patch is to set member to empty when
there are no remaining candidates. This changes the above sequence as follows.

delete member-1
delete member-2
delete member-3
delete member-1 succeeds so choose new owner - in this case member-2
make-owner member-2
delete member-2 succeeds - member-2 is not the current owner so do nothing
delete member-3 succeeds - member-3 is the last candidate so set member to ""
make-owner ""
make-owner member-2 succeeds. Now we have an owner for entity-1 even though we have not candidates
make-owner "" succeeds. Now we have owner for entity-1 set to no one as it should be

Introduce EntityOwnerSelectionStrategy

Currently the EntityOwnershipService does not do any load
balancing, in that it allows the first candidate that registers
to become an owner. There is a need to do that so that applications
which choose to do some *work* based on if it owns an entity can
scale better.

This patch introduces the concept of an EntityOwnerSelectionStrategy
with the intent to provide custom strategies later to choose an owner.

Since custom strategies require intimate knowledge of how the
EntityOwnershipShard chooses a leader at this time I do not think
a strategy can be passed to the EntityOwnershipService via API. The
intent therefor is to choose a strategy based on configuration
wherein a custom strategy can be chosen for each entity type. If
the Strategy needs any custom configuration then it can have configuration
files of it's own

Always persist ServerConfigurationPayload log entries

We need to always persist ServerConfigurationPayload log entries
regardless of whether or not persistence is enabled for the derived
RaftActor's data.

I added a new tagging interface PersistentPayload, implemented by
ServerConfigurationPayload, to indicate a Payload
needs to always be persisted. Since log entries are persisted by
both the RaftActor and Follower behavior via the ReplicatedLog, the
logic to determine persistence based on PersistentPayload needs to be
available to both. The ReplicatedLog uses the persistence provider
contained in the RaftActorContext which is the
DelegatingPersistentDataProvider set by the RaftActor. So to keep
the rest of the code the same and keep it simple, I derived a
RaftActorDelegatingPersistentDataProvider which overrides persist to
handle the PersistentPayload logic utilizing the RaftActor's
existing PersistentDataProvider.

Bug 2187: AddServer unit test and bug fixes

Follow-up patch to https://git.opendaylight.org/gerrit/#/c/28018/.

Got the unit tests working and added more unit tests to cover more code.

Also fixed several bugs in the code that were failing the tests. One bug
was caused by replicating data quickly after install snapshot was
complete. On the final install snapshot chunk the follower sends an
ApplySnaphot message to persist and apply the snapshot. On the reply,
the leader assumes the follower is up-to-date and sets its next index.
However, applying the snapshot, ie updating the log and commit index, is
actually done after the async callback from the snapshot persist. In between
that time, if the leader sends the server config AppendEntries, the follower's
log is still empty and it deems itself out-of-sync and reports back failure.
This will cause the leader to eventually send a new install snaphot
which isn't which is not desirable. Also it may delay consensus for the
server config entry.

To fix this, I delayed the final InstallSnapshotReply until after the
ApplySnapshot is complete. I did this by adding a Callback to the
ApplySnapshot message which the SnapshotManager invokes.

Also the new server config was constructed without the leader's ID - it
needs to contain all members.

Also the ServerConfigurationPayload wasn't being applied in the
followers.

Another issue was that, if the leader had no peers initially, the
heartbeat wasn't scheduled so, when the new server was added, heartbeats
weren't occurring. So I change addFollower to schedule the heartbeat.

I added a test for adding a non-voting server which caused an endless
loop in AbstractLeader#handleAppendEntriesReply where it updates the
commitIndex based on the replicated count. To fix this, I added a break
if the replicatedLogEntry is null.

pax-url-aether provides javax.inject and commons-codec, but they need
to be declared separately for correctness and to allow upgrades to
newer versions of pax-url-aether.

com.google.inject.Inject can be replaced by javax.inject.Inject.

4 years agoFix ModuleFactory not found errors 11/28211/5

Fix ModuleFactory not found errors

https://git.opendaylight.org/gerrit/#/c/27874/ improvements to the
config system but had the side-effect of introducing timing issues where
a ModuleFactory wasn't found when trying to push a config. The reason is
that yang schemas load earlier and much quicker than ModuleFactory's,
which are scanned from ACTIVE bundles, so the capabilities may resolve
but a ModuleFactory may not be available yet. As a result, that patch
was partially reverted for the time being.

To fix the missing ModuleFactory issue, I added retries in the
ConfigPusherImpl when a ModuleFactory isn't found, similar to the
ConflictingVersionException retries. The backend now throws a new
checked exception, ModuleFactoryNotFoundException, which is caught to
trigger a retry after a delay. Prior, it threw an
InstanceNotFoundException which was wrapped in an
IllegalArgumentException. I didn't keep the InstanceNotFoundException
b/c it can be thrown for other reasons and I wanted to distinguish
missing ModuleFactoryNotFoundException.

I derived ModuleFactoryNotFoundException from RuntimeException to avoid
having to change signatures in the call chain and thus changing the API.
Prior it threw an unchecked IllegalArgumentException anyway so it's
consistent plus other areas of the code throw unchecked exceptions along
with checked exceptions.

Since the missing ModuleFactory issue is fixed, I re-enabled scanning of
RESOLVED bundles in the ModuleInfoBundleTracker.

4 years agoBUG 4151 : Create a shared actor system 62/27562/9

BUG 4151 : Create a shared actor system

This patch adds an ActorSystemProvider interface in clustering commons
with a method to get a shard ActorSystem instance which uses the
clustered data store configuration as it contains more configuration
options than the rpc connector which pretty much uses stock configuration.
I added a config yang to define an actor-system-provider-service.

I added the ActorSystemProvider implementation and actor-system-provider-impl
config yang in the distributed datastore bundle. I tried it in
sal-clustering-commmons originally but ran into akka errors re: missing
config properties and it also couldn't find the
ReadyLocalTransactionSerializer class. So to avoid chasing down those
errors I put the implementation in sal-distributed-datastore. I think
this makes sense as it is the prime user of the actor system.

I added a dependency for the ActorSystemProvider service in both
datastores modules so the ActorSystem is now injected in and passed
to the DistributedDataStoreFactory. The dependency was also added to the
RPC mpdule.

Elements for the new actor system provider service and impl were added to
the 05-clustering.xml file along with the wiring changes for the data
stores and RPC modules.

4 years agoRemove peer address cache in ShardInformation 60/27760/4
Tom Pantelis [Thu, 1 Oct 2015 13:27:40 +0000 (09:27 -0400)]
Remove peer address cache in ShardInformation

The ShardManager caches the peer addresses in the ShardInformation and
uses it mainly to suppress PeerUp, PeerDown and PeerAddressResolved
messages to the shard for peers that don't have replicas for the shard.

This is fine with static config but With the upcoming work to dynamically
add replicas, the shard will take ownership of persisting its peers so
the ShardManager will not know about dynamic peers.

I changed the semantics of the peer addresses to initial peer addresses.
They are now only used to pass to the Shard on creation. As a result,
PeerUp, PeerDown and PeerAddressResolved messages are now always sent to
the Shard for all peers. The Shard/RaftActor decide ll whether or not to
process the peer message. I changed RaftActorContextImpl#setPeerAddress
to ignore a peerId it doesn't know about instead of throwing an ex.

The other usages of the peerAddresses were to lookup the leader address.
This is now done dynamically via the ShardPeerAddressResolver.
