They make no sense. Fixes preview2 testnet state problem:
file BlockStorage_100000/dump-block-70000.json: block 69935: state mismatch for key ffffffff1454a6cb279fbcedc66162ad4ad5d1d910202b92743e000000000000000000000005: Deleted vs Added
Preview2 testnet:
file BlockStorage_100000/dump-block-12000.json: block 11562: key mismatch: feffffff1454a6cb279fbcedc66162ad4ad5d1d910202b92743e000000000000000000000005 vs feffffff1431b7e7aea5131f74721e002c6a56b610885813f79e000000000000000000000005
Originally this code was written to run after transactions processing, but
after 0fa4c49735 it works in different manner.
ValidatorsCount is not initialized at block 0 with C# node (the first voter
initializes it) and until that initialization happens the standby validators
list is being returned as is without sorting.
Fixes state mismatch for the key ffffffff0e00000000000000000000000000000001 in
the first blocks.
It also affects tests as now the first validator is different and it receives
the network fees.
MarshalJSON should be defined on structure (not pointer), as we use
structures to marshal parameters (e.g. in NotificationEvent and
Invoke of RPC result package) and never use pointers for that purpose.
Also added marshalling of nil array into `[]` instead of `null` to
follow C# implementation.
C# implementation uses NEWARRAY for creating arguments.
Don't change our implementation in `emit`, because PACK is cheaper and
this script must not depend on the internal details of `emit` package anyway.
When money is being sent usually they go away from someone's pocket, so that
there is a little less money left there. Not in our case as it turns out, we
actually were adding money both to sender and receiver which is nice, but a
bit different from usual economic's expectations.
`NewNEO()` and `NewGAS()` methods are trying to initialise
both `onPersist` and `incBalance` methods of NEO and GAS AFTER
nep5TokenNative is set to the VALUE of created nep5 token.
In this situation an attemmpt to call the corresponding native contracts
methods (e.g. transfer native GAS) leads to contract invocation failure,
as far as `nep5TokenNative.incBalance` method is nil.
Fixed this by initializing both `onPersist` and `incBalance` methods
before getting the value of nep5 contract.
The notion of NativeContractState shouldn't ever existed, native contract is a
contract and its state is saved as regular contract state which is critical
because we'll have MPT calculations over this state soon.
Initial minting should be done in Neo.Native.Deploy because it generates
notification that should have proper transaction context.
RegisterNative() shouldn't exist as a public method, native contracts are only
registered at block 0 and they can do it internally, no outside user should be
able to mess with it.
Move some structures from `native` package to `interop` also to avoid circular
references as interop.Context has to have a list of native contracts (exposing
them via Blockchainer is again too dangerous, it's too powerful tool).
