eeeb0f6f0e core: accept two-side channels for sub/unsub, read on unsub 
Blockchain's notificationDispatcher sends events to channels and these
channels must be read from. Unfortunately, regular service shutdown procedure
does unsubscription first (outside of the read loop) and only then drains the
channel. While it waits for unsubscription request to be accepted
notificationDispatcher can try pushing more data into the same channel which
will lead to a deadlock. Reading in the same method solves this, any number of
events can be pushed until unsub channel accepts the data.

88542630ac blockchainer: drop the package completely 
It's not an ideal solution, but at least it solves the problem for
now. Caveats:
 * consensus only needs one method, so it's mirrored to Blockchain
 * rpcsrv uses core.* definition of the StateRoot (so technically it might as
   well not have an internal Ledger), but it uses core already unfortunately

Specifying a certain stateroot R as `invoke*historic` RPC-call

state of root R. Thus, next block should be of the height h(R)+1. This

d70caf1da1 core: move GetScriptContainer to runtime 
It also brings ToStackItem to Block and Transaction, previously this was
avoided to separate block and transaction packages from VM. But turns out
`transaction` depends on `stackitem` already, so this makes little sense (but
can be shuffled in another way if needed).

Context.Container is still a hash.Hashable because we have a number of
occasions (header or MPT root verification) where there is no ToStackItem
implementation possible. Maybe they can go with `nil` Container, but I don't
want to have this risk for now.

appends which is a better approach anyway. rootpath is required because
current directory will change from package to package.

1472c271e6 core: fix native NEO's getCandidateVote signature 
This commit fixes T5 statediff at block #0. Management's storage item
differs between neo-go and C# nodes, the reason in native NEO contract
state.

The parameter should have `pubKey` name, unlike the other `pubkey`
arguments in this contract.

ca127f1615 core: fix native NEO ABI 
This commit fixes T5 statediff at block #0. The reason in Management's
storage state. The diff occurs because of inconsistent NEO methods
order. See
https://github.com/neo-project/neo/issues/2766#issue-1257870089.

The current solution is to preserve C#'s order of methods to be
compatible with current testnet.

400cbde32c state: optimize allocations in (*NEP17Transfer).EncodeBinary 2022-06-02 15:38:39 +03:00
Roman Khimov
9a06995460 bigint: don't allocate in ToPreallocatedBytes 
Turns out, it's almost always allocating because we're mostly dealing with
small integers while the buffer size is calculated in 8-byte chunks here, so
preallocated buffer is always insufficient.

name                   old time/op    new time/op    delta
ToPreallocatedBytes-8    28.5ns ± 7%    19.7ns ± 5%   -30.72%  (p=0.000 n=10+10)

name                   old alloc/op   new alloc/op   delta
ToPreallocatedBytes-8     16.0B ± 0%      0.0B       -100.00%  (p=0.000 n=10+10)

name                   old allocs/op  new allocs/op  delta
ToPreallocatedBytes-8      1.00 ± 0%      0.00       -100.00%  (p=0.000 n=10+10)

Fix StorageItem reuse at the same time. We don't copy when getting values from
the storage, but we don when we're putting them, so buffer reuse could corrupt
old values.
