If blockchain is not closed, logging in defer can occur
after test has finished, which will lead to a panic with
"Log in goroutine after Test* has completed".
This seriously improves the serialization/deserialization performance for
several reasons:
* no time spent in `binary` reflection
* no memory allocations being made on every read/write
* uses fast ReadBytes everywhere it's appropriate
It also makes Fixed8 Serializable just for convenience.
add dao which takes care about all CRUD operations on storage
remove blockchain state since everything is stored on change
remove storage operations from structs(entities)
move structs to entities package
It reduces heap pressure a little for these elements as we don't have to
allocate/free them individually. And they're directly tied to transactions or
block, not being shared or anything like that, so it makes little sense for
them to be pointer-based. It only makes building transactions a little easier,
but that's obviously a minor usecase.
Drop wif.GetVerificationScript(), drop
smartcontract.CreateSignatureRedeemScript(), add GetVerificationScript()
directly to the PublicKey and use it everywhere.
This allows easier reuse of opcodes and in some cases allows to eliminate
dependencies on the whole vm package, like in compiler that only needs opcodes
and doesn't care about VM for any other purpose.
And yes, they're opcodes because an instruction is a whole thing with
operands, that's what context.Next() returns.
Param getters were redone to return errors because otherwise bad FuncParam
values could lead to panic. FuncParam itself might be not the most elegant
solution, but it works good enough for now.
This PR does 3 things:
adds array parameter unmarshalling
extend Param with convenient methods
refactor tests into using tables to make it easier add new tests
(part of #347 solution)
There is a difference in interpretation of what a block count is. neo-go nodes
currently respond to this request with the latest block number which is the
same number that neoscan.io shows. However, C# nodes deliberately do add one
to this number when answering to the getblockcount request to account for the
genesis block number 0.
This patch makes us consistent with C# nodes wrt to getblockcount behaviour.
