In previous implementation Object service's handler returned const error in

In recent changes, the locality criterion for a node has been changed to

Remove no longer used `IsLocalAddress` function and `LocalAddressSource`
interface.
Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
Some software components regulate the way of working with placement arrays
when a local node enters it. In the previous implementation, the locality
criterion was the correspondence between the announced network address
(group) and the address with which the node was configured. However, by
design, network addresses are not unique identifiers of storage nodes in the
system.
Change comparisons by network addresses to comparisons by keys in all
packages with the logic described above. Implement `netmap.AnnouncedKeys`
interface on `cfg` type in the storage node application.

Since morph `Client` works in multi-client mode, there is an error case when

Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
There is a need to work with a set of Neo RPC nodes in order not to depend
on the failure of some nodes while others are active.
Support "multi-client" mode of morph `Client` entity. If instance is not
"multi-client", it works as before. Constructor `New` creates multi-client,
and each method performs iterating over the fixed set of endpoints until
success. Opened client connections are cached (without eviction for now).
Storage (as earlier) and IR (from now) nodes can be configured with multiple
Neo endpoints. As above, `New` creates multi-client instance, so we don't
need initialization changes on app-side.
`Wait` and `GetDesignateHash` methods of `Client` return an error from now
to detect connection errors. `NotaryEnabled` method is removed as unused.

In previous implementation Container service handlers didn't cache the

Construct wrapper over the Container contract client with `TryNotary` option
since it is required to perform invocations of notary contract.
Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
All client wrappers should use underlying static client with enabled notary
work mode in order to produce invocations of notary contract.
Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
Some of the client wrapper's methods should produce notary contract's
invocations. In previous implementation all wrappers provided separate
methods to do it. Since notary and non-notary invocation scenarios have very
different goals, it makes sense to separate the scenarios of using the
client wrapper at the stage of its creation.
Define `Option` constructor for container client wrapper. Add `TryNotary`
option which enables tries of the notary invocations on underlying static
client. Mark all notary-dedicated methods as deprecated.
Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
There are two scenarios of invocation of contract methods:
1. do not invoke notary contract;
2. try to invoke notary contract if it is enabled in Client.
Taking this into account, `StaticClient` can work in one of the two described
modes. Based on this, it makes sense at the stage of creating `StaticClient`
to fix the call mode, and the further abstract from it.
Define `StaticClientOption` setters of `StaticClient` optional parameters.
Add `TryNotary` constructor of option which enables notary tries. Call
`NotaryInvoke` on underlying `Client` if the option is provided, otherwise
call `Invoke`. Mark `NotaryInvoke` method of `StaticClient` as deprecated.

Alphabet nodes synchronize list of alphabet keys from main chain
`NeoFSAlphabet` role once per epoch. This can lead to a wrong behavior in

in single chain environment will try to get NeoFSAlphabet role from main
chain client, but it'll get result from side chain instead. Side chain
