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.

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.

BUG 4151 : Create a shared actor system

This patch adds an ActorSystemProvider interface in clustering commons

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.

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.

Modify ModuleInfoBundleTracker to track RESOLVED bundles (round 2)

My first patch https://git.opendaylight.org/gerrit/#/c/27138/ didn't
do well with the feature tests due the BundleContext bust wait so it
was reverted.

I went back to my original solution to confgure the ModuleInfoBundleTracker
to track RESOLVED and ModuleFactoryBundleTracker to track ACTIVE.
Originally when I tried that I had some failure due to the ModuleFactory
not loaded yet but I don't remember exactly what. This patch seems to work
fine - I've restarted karaf several times and also ran the tsdr features tests
several times successfully. Originally I did the first patch in stable/lithium
so maybe something else has changed in master or the way I did it wasn't right.

Since the initial yang module info's are now processed synchronously when the
BundleTracker is opened, I modified the ModuleInfoBundleTracker to
ensure it doesn't propagate runtime ex's. This would disrupt the
BundleTracker and the ConfigManagerActivator - if one module had an
issue the config manager wouldn't start.

For every YangModuleInfo scraped, it registers it with the
ModuleInfoRegistry. The backing impl is RefreshingSCPModuleInfoRegistry
which causes a new SchemaContext to be created from the current yang
models (via updateService). This isn't efficient - on startup, we'll get all
YangModuleInfo's in quick succession so, optimially, it should build the
SchemaContext once after open is complete. This is what the
GlobalBundleScanningSchemaServiceImpl does.

To accomplish this, I removed the call to updateService from
RefreshingSCPModuleInfoRegistry#registerModuleInfo - it is now
specifically called by ModuleInfoBundleTracker. This means the
ModuleInfoBundleTracker now references RefreshingSCPModuleInfoRegistry
instead of the ModuleInfoRegistry interface which makes it less clean.
Any other way would require changes to the ModuleInfoRegistry interface,
which I didn't want to do, or extending the interface which I didn't think that
was worth the effort. The RefreshingSCPModuleInfoRegistry is only used by
ModuleInfoBundleTracker.

mostly initial skeleton code. In RaftActorServerConfigurationSupport,
I implemented the basic checks for leader avaialbility with
corresponding unit tests. If not the leader and there is a leader, it
forwards to the remote leader. If no leader, it returns NO_LEADER
failure.

Also in RaftActorServerConfigurationSupport, I added code for the first
steps: add the serverId/address into the RaftActorContext peer map and
add a FollowerLogInformation entry in the AbstractLeader. I added an
initialized field wih getters/setters to FollowerLogInformation. The
entry is added with initialized set to false. I also changed the
followerToLogMap in AbstractLeader to mmutable.

I also modified FollowerLogInformationImpl so it returns false for
isFollowerActive and isOkToReplicate if initialized is false. The idea
is to prevent the leader from sending log entries or a snapshot via
the heartbeat or replication. The leader will send an empty
AppendEntries
heartbeat which should be fine. The RaftActorServerConfigurationSupport
will initiate the install snapshot directly.

I added TODO comments in RaftActorServerConfigurationSupport and the
unit test class which outline the remaining work.

entries.

5 years agoFix ModuleFactoryBundleTracker shutdown hang 26/27626/2
Tom Pantelis [Mon, 28 Sep 2015 07:49:46 +0000 (03:49 -0400)]
Fix ModuleFactoryBundleTracker shutdown hang

If karaf is shutdown quickly after starting, the
ModuleFactoryBundleTracker#getModuleFactoryEntries method may
hang for a while trying to obtain BundleContexts. This has
been seen on jenkins with some feature tests. The ModuleFactoryBundleTracker
does a 1 min busy wait trying to obtain the BundleContext. This was done b/c the
tracker listens for RESOLVED bundles and the BundleContext isn't available
until after the bundle is started. So the busy wait was intended for startup
when bundles transition from RESOLVED -> STARTING. Once obtained, the
BundleContext is cached.

This works fine normally when all bundles start up. However, if stopped
quickly, some bundles may not have started, ie they remain in the
RESOLVED state with null BundleContext, so on shutdown when someone
calls getModuleFactoryEntries, it will busy wait and eventually timeout which
can take minutes.

What we need to do is remove the ModuleFactory entries when bundles are
stopped. The ModuleFactoryBundleTracker#removedBundle method does this
but it wasn't called on shutdown b/c it tracks RESOLVED, STARTING, ACTIVE
and STOPPING states. The solution is to remove STOPPING from the tracked states
so removedBundle will get called on transition ACTIVE -> STOPPING.
However, when transition STOPPING -> RESOLVED occurs the bundle will get
added back to the tracker and we don't want to re-add the ModuleFactory
entries. To prevent this it checks for BundleEvent type STOPPED.

5 years agoModify ModuleInfoBundleTracker to track RESOLVED bundles 38/27138/5
Tom Pantelis [Sun, 13 Sep 2015 03:55:29 +0000 (23:55 -0400)]
Modify ModuleInfoBundleTracker to track RESOLVED bundles

I've seen issues where a yang-generated class that exists in another
bundle isn't found on startup when a module config is pushed.
Specifically I've seen it when registering RPC implementations. The
BindingDOMRpcProviderServiceAdapter uses the
BindingToNormalizedNodeCodec get the RPC schema and it can fail to
get the RPC input class.

The BindingToNormalizedNodeCodec calls the BindingRuntimeContext to
obtain schema classes which in turn uses the ClassLoadingStrategy OSGi
service to load classes. The backing implementation of
ClassLoadingStrategy is the ModuleInfoBackedContext supplied by the
config manager bundle. This is backed by the ModuleInfoBundleTracker
which scrapes yang files from bundles. However it listens for ACTIVE
bundles. A while ago the GlobalBundleScanningSchemaServiceImpl was
(correctly) changed to listen for RESOLVED bundles which fixed startup
timing issues. It makes sense to also change the
ModuleInfoBundleTracker to listen for RESOLVED bundles so all existing
yang models are loaded on startup prior to use.

The ModuleFactoryBundleTracker piggy-backs the ModuleInfoBundleTracker
to load ModuleFactory instances needed by the config system. It
registers ModuleFactory instances as OSGi services, which are consumed by the
BundleContextBackedModuleFactoriesResolver, however this fails for a
RESOLVED bundle b/c it doesn't have a BundleContext yet (apparently this
is set when the bundle is started/activated). To fix this, I refactored
BundleContextBackedModuleFactoriesResolver and
ModuleFactoryBundleTracker a bit. The ModuleFactoryBundleTracker no
longer registers ModuleFactory instances as OSGi services. Instead it
maintains a list of ModuleFactory/Bundle entries which the
BundleContextBackedModuleFactoriesResolver directly uses to build the
resulting factories map for the ConfigRegistry. A bundle may still not
have a BundleContext at that point so, to safe guard against that, I
added a busy wait for BundleContext.

Bug 4094: Fix DCNs on initial registration

For DataChangeListener, I modified the code to use a
ResolveDataChangeEventsTask to resolve the initial changed event. It
was noted in Bug 4094 to read the registration path up to the first
wildcard. However this did not work. ResolveDataChangeEventsTask
expects the candidate root path and "after" data to be the tree root
to match the structure of the ListenerTree. When a transaction is
committed, the resulting DataTreeCandidate always points to the root.
So I had to read the root path in ShardDataTree. I could've optimized
for non-wildcarded path registrations but I think wildcarded path
registrations will be the norm anyway.

I added a new method, notifyOfInitialData, in ShardDataTree. Because I
had to create a new ListenerTree with the single registration, I
needed to know the path and scope of the original registration so I
changed several method signatures from the general ListenerRegistration
to the specific DataChangeListenerRegistration which provides access to
the path and scope. However we also have an actor class by that name so
to avoid confusion I renamed the actor class to
DataChangeListenerRegistrationActor.

DataTreeChangeListener was implemented similarly.

Tom Pantelis [Tue, 18 Aug 2015 06:59:47 +0000 (02:59 -0400)]
Bug 4105: Remove candidates on PeerDown

Currently on PeerDown, the EntityOwnershipShard selects a new owner for
the entities owned by the down node and leaves the down node as a
candidate. If the down node is the only candidate, the owner is cleared.
On PeerUp, it selects a new owner for those entities whose owner is clear.
This was done to handle network partition so a node's candidates remain
registered and are re-assigned when the partition is healed.

Howver this has potential issues when a node is actually
stopped/restarted. It's possible, on restart, that the node doesn't
register a candidate for an entity that it had previously registered for.
So it may get ownership of an entity for which it has no registered
candidate.

To alleviate this, I changed it to remove all the down node's candidates
on PeerDown. If the node was stopped/restarted, then it will
re-register candidates based on local client requests. This case will be
the norm. To handle network partition, when healed, the follower node
will get the replicated commits for its candidate removals from the
leader. So on Candidate removed, it re-adds its removed candidate if it
has a registered EntityOwnershipCandidate.

I realized that one can register a DOMDataTreeChangeListener for a leaf
node. So I simplified EntityOwnerChangeListener to listen for the owner
leaf instead of the entity path. This avoids the extra notifications
when candidayes are added/removed. I actually did this originally b/c I
thought there was a bug when listening at the entity level which turned
out there wasn't but I left it in as an improvement.

I also added the shard's logId to the listener and support classes for
better debugging of unit tests.

Bug 4105: Change ownership on member down/up

Added 2 new messages, PeerUp and PeerDown, that the ShardManager sends
in response to cluster member events.

For PeerDown, the EntityOwnershipShard finds the entities owned by the
down member and selects a new owner based on the remaining candidates.
If there's no other candidates, the owner is cleared (set to "") so new
candidates can become owner. The down members are also tracked via a
downPeerMemberNames set.

For PeerUp, if the up member is in the downPeerMemberNames, the
EntityOwnershipShard finds entities that previously had their owner
cleared and attempts to select a new owner. This handles the case where
a previously down member was the only candidate for an entity so, when
that member comes back up, the entity's owner will be re-assigned to
that member.

Reassigning of owners via PeerDown and PeerUp is only done on the
leader. However that may not handle the case where the leader goes down.
When a new leader is elected we need it to select new owners for
entities owned by the down leader. There are 2 cases here. If the old
leader has not yet been detected as down then eventually we expect to
get PeerDown to handle it. The second case is if PeerDown was already
received prior to the leader change (probably the norm), in which case
PeerDown would not have been processed. To handle this case I overrode
onLeaderChanged to select new owners for entities owned by the old leader
that is passed in. The RaftActor sends the old leader's peerId so I
added a peerIdToMemberNames map to translate - this is populated via
PeerUp. Also I changed the RaftActor to track and pass the actual last valid
leader id, previously it passed the leader id from the previous behavior
which would normally be Candidate which always has a null leaderId.

The newOwner method was changed to ignore candidates in the
downPeerMemberNames set as there's no point in assigning the owner to a
candidate known to be down.

multiple impls - I put this in sal-common-api where the
EntityOwnershipService is defined.

BUG 2185: Expand the scope of sync status to cover a slow follower

Previously sync status was used only in the startup scenario
to make the controller appear to the external world as not
synced up unless it had received atleast data till the commitIndex
which the leader reported when it sent the follower it's first
heartbeat.

Now we also track when a new update is sent from the Leader to the
Follower and if the Follower is behind the Leader by a threshold
(hardcoded for now) then we consider the Follower as out-of-sync

Also I added the member name in the ShardManager bean so that is another
place from which we can figure out on which node we are running.

it has additional entries in it's log which are missing in the Leader. When the
