a003879b84 native: avoid allocations in increaseBalance 2021-12-02 15:33:30 +03:00

418ba1dbc3 *: use internal variables for simple big.NewInt() values 
Avoid additional allocations.

ce9d0b22cf *: use NEP-XX naming consistently in docs/comments 
Standards are NEP-11 and NEP-17, not NEP11, not NEP17, not anything
else. Variable/function names of course can use whatever fits, but documents
and comments should be consistent wrt this.

f96d9d168e native/interop: use oracle request signers for oracle response witness 
Oracle responses must use the same set of signers as oracle requests even
though the transaction itself is signed by oracle nodes/contract.

We can probably improve interop.Context by removing Tx field completely and
adding more functionality to Container, but it's not very convenient for
VerifyWitness and will require adding more stub-like methods for Block, so Tx
is used for now (and we do have it in every relevant case).

b66bc33cf9 native: short-circuit successive GAS distributions 
GAS can only be distributed once in a block for particular address, so it
makes little sense trying to calculate it again and again. This fixes
neo-bench for NEO voter, because without it we get ~2500 TPS for
single-address test and with it it jumps 13-fold to normal values like
~33500.

c113d682bd core: fix NEO balance state handler 
We need to store NEO balance's LastUpdateHeight before GAS mint,
because mint can call onNEP17Payment and onNEP17Payment can call NEO
transfer which also calls GAS mint. Storing balance height allows to
avoid recursion.

5c65d33439 native: move required balance check to token contracts 
Which duplicates the check, but deduplicates error path. This check forced
double balance deserialization which is quite costly operation, so we better
do it once.

It's hardly noticeable as of TPS metrics though, maybe some 1-2%%.

d49294b046 core: fix the way candidates are sorted 
(*NEO).GetCandidates along with getCandidatesCall use candidates sorted
by serialized ECPoint bytes.

(*NEO).computeCommitteeMembers use candidates sorted by votes, and then
by deserialized ECPoint, i.e. using default ECPoint comparator.

NEP17 roundtrip is prohibited if from account doesn't have enough funds.

This commit fixes states diff in block 92057 where account

amount exceeding the account's balance:
