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
Closes#913.
Provide package info in the funcScope to check if function is defined
insided an interop package. As a good side-effect bytecode for builtins from `util`
is no longer emitted.
Related #941.
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.
It's useless. Even though there is Neo.Transaction.GetUnspentCoins syscall
that can be used, its return type is an interop structure that's not accepted
by any other syscall, so you can't really do anything with it. And there is no
such interface for the .net Framework.
By default VM initializes every field of a new struct to a Boolean.
If field contains another struct, we need to initialize it to default
value explicitly. This commit sets default values for uninitialized
field.
Before introducing slots it was hard to change global variables
preserving changes across multiple function calls.
This commit implements such possibility.
Closes#638.
1. Slot is a new mechanism for storing variables during execution
which is more convenient than alt.stack. This commit implements
support for slot opcodes in both vm and compiler.
2. Remove old alt.stack opcodes.
3. Do not process globals at the start of every function, but instead
load them single time at main.
