Part of #1055.
It should have `AllowStates` flag.
Also removed unreachable code: we can't have such situation when
script container is not a transaction in the scope of `CheckWitness`
method because:
1. Blocks have their own implementation of CheckWitness for
internal usage (it's (bc *Blockchain) verifyHeaderWitnesses method).
2. For the outside calls of System.Runtime.CheckWitness interop (e.g.
calls from smart-contract) script container is always a transaction.
1. Remove GetScript, IsPayable, GetStorageContext.
2. Revert 82319538 related to GetStorageContext.
3. Rename Migrate to Update.
4. Move remaining to System.Contract.*.
Related #1031.
Updated System.Blockchain.GetBlock interop replaced the functionality of
the following interops:
System.Block.GetTransactions
System.Block.GetTransactionCount
Neo.Block.GetTransactions
Neo.Block.GetTransactionsCount
closes#1025
Now we put on stack stackitem.Array instead of Interop, so we're able to
use all available block properties without extra interop getters.
Removed Neo.Blockchain.GetBlock interop as we don't need it anymore.
Removed Neo.Block.GetTransaction and System.Block.GetTransaction
interops. These interops were replaced by new
System.Blockchain.GetTransactionFromBlock interop.
closes#1023
Now we put on stack stackitem.Array instead of Interop, so we don't
need old transaction-related interops anymore. Removed the following
interops:
System.Transaction.GetHash
Neo.Transaction.GetAttributes
Neo.Transaction.GetHash
Neo.Transaction.GetWitnesses
Neo.Attribute.GetData
Neo.Attribute.GetUsage
Also removed the following duplicated NEO interop:
Neo.Blockchain.GetTransaction
Two changes being done here, because they require a lot of updates to
tests. Now we're back into version 0 and we only have one type of
transaction.
It also removes GetType and GetScript interops, both are obsolete in Neo 3.
1. Dropped `Base.ConsensusData` block field
2. Added `Block.ConsensusData` field with `Nonce` and `PrimaryIndex`
3. Removed "Neo.Header.GetConsensusData" and
"AntShares.Header.GetConsensusData" interops
This solves two problems:
* adds support for shortened SYSCALL form that uses IDs (similar to #434, but
for NEO 2.0, supporting both forms), which is important for compatibility
with C# node and mainnet chain that uses it from some height
* reworks interop plugging to use callbacks rather than appending to the map,
these map mangling functions are clearly visible in the VM profiling
statistics and we want spawning a VM to be fast, so it makes sense
optimizing it. This change moves most of the work to the init() phase
making VM setup cheaper.
Caveats:
* InteropNameToID accepts `[]byte` because that's the thing we have in
SYSCALL processing and that's the most often usecase for it, it leads to
some conversions in other places but that's acceptable because those are
either tests or init()
* three getInterop functions are: `getDefaultVMInterop`, `getSystemInterop`
and `getNeoInterop`
Our 100K (1.4M->1.5M) block import time improves by ~4% with this change.
Importing 100K blocks starting at 1.4M, before this patch:
real 6m0,356s
user 8m52,293s
sys 0m47,372s
After this patch:
real 4m17,748s
user 6m23,316s
sys 0m37,866s
Almost 30% better.
