Test coverage is automatically enabled when go test is running with coverage
enabled. It can be disabled for any Executor by using relevant methods.
Coverage is gathered by capturing VM OPs during test contract execution and

9 fields vs 10, notice the primary index right after the block number.
Back when ac527650eb initially added Ledger I've
used https://github.com/neo-project/neo/pull/2215 as a reference and it was
correct (no primary index). But then https://github.com/neo-project/neo/pull/2296
came into the C# codebase and while it looked like a pure refactoring it
actually did add the primary index as well and this wasn't noticed. It wasn't
noticed even when 3a4e0caeb8 had touched some
nearby code. In short, we had a completely wrong implementation of this call
for more than three years. But looks like it's not a very popular one.

Every client's (Un)Subscription call does two things: an RPC call and a
subscription map lock (two of maps currently). If we imagine that there is
one routine that tries to subscribe (A) and one routine that tries to
unsubscribe (B), the following sequence can happen:
0. Current number of subscriptions is X
1. B does an RPC and makes number of subscriptions X-1
2. A does an RPC and makes number of subscriptions X again
3. A holds subscription locks and rewrites client's subscription state
(subscription with ID X now points to a different channel; channel that
was registered by B is lost and is not related to any real subscription
but is still included in the `receivers` map)
4. B holds subscription locks and drops subscription X (first, it is an
error and we have just lost a subscription that we think was made
successfully second, we have lost a channel in the `receivers` map, and
no corresponding subscription points to it)
5. X subscription is received by the WS client (in practice it is a new
block, 100ms, quite often to be sure this issue happens every hour), we
range through the receivers, see no corresponding subscription, and
panic.

Refs. #3522. The core problem is the same as for groups/features: we can't
allow empty trusts when they're unmarshalled from JSON. But unlike others we
can't easily differentiate missing any value with other cases because the
default value for WildPermissionDescs is a valid thing. Adding an additional
field makes it invalid and we can build around it. Other options are
implementing custom UnmarshalJSON for Manifest (too much for this) or making
Trusts a pointer (an option, but can fail in too many ways).

It's not correct to use an updated contract state got from Management to
check for the allowed method call. We need to use manifest from the
currently executing context for that. It may be critical for cases when
executing contract is being updated firstly, and after that calls
another contract. So we need an old (executing) contract manifest for
this check.
This change likely does not affect the mainnet's state since it's hard
to meet the trigger criteria, but I'd put it under the hardfork anyway.

This test ensures that NeoGo node doesn't have the DeepCopy problem
described in https://github.com/neo-project/neo/issues/3300 and fixed in
https://github.com/neo-project/neo/pull/3301. This problem leads to the
fact that Notifications items are not being properly refcounted by C#
node which leads to possibility to build an enormously large object on
stack. Go node doesn't have this problem.
The reason (at least, as I understand it) is in the fact that C# node
performs objects refcounting inside the DeepCopy even if the object
itself is not yet on stack. I.e. System.Runtime.Notify handler
immediately adds references to the notification argumetns inside
DeepCopy:
b1d27f0189/src/Neo.VM/Types/Array.cs (L108)b1d27f0189/src/Neo.VM/Types/Array.cs (L75)
Whereas Go node just performs the honest DeepCopy without references counting:
b66cea5ccc/pkg/vm/stackitem/item.go (L1223)
Going further, C# node clears refs for notification arguments (for array
and underlying array items). System.Runtime.GetNotifications pushes the
notificaiton args array back on stack and increments counter only for
the external array, not for its arguments. Which results in negative
refcounter once notificaiton is removed from the stack. The fix itself
(f471c0542d/src/Neo/SmartContract/NotifyEventArgs.cs (L84))
doesn't need to be ported to NeoGo because Go node adds object to the
refcounter only at the moment when it's being pushed to stack by
System.Runtime.GetNotifications handler. This object is treated as new
object since it was deepcopied earlier by System.Runtime.Notify handler:
b66cea5ccc/pkg/vm/stack.go (L178).
Thus, no functoinal changes from the NeoGo side. And we won't
intentionally break our node to follow C# pre-Domovoi invalid behaviour.

And thus, we must treat this transaction as valid for this behaviour
to be reproducable.
This commit contains two fixes:
1. Do not overwrite block executable records by conflict record stubs.
If some transaction conflicts with block, then just skip the conflict
record stub for this attribute since it's impossible to create
transaction with the same hash.
2. Do not fail verification for those transactions that have Conflicts
attribute with block hash inside. This one is controversial, but we
have to adjust this code to treat already accepted transaction as
valid.

Replace native CryptoLib's verifyWithECDsa `curve` parameter by
`curveHash` parameter which is a enum over supported pairs of named
curves and hash functions.
Even though this change is a compatible extension of the protocol, it
changes the genesis state due to parameter renaming. But we're going to
resync chain in 3.7 release anyway, so it's not a big deal.
Also, we need to check mainnet and testnet compatibility in case if
anyone has ever called verifyWithECDsa with 24 or 25 `curve` value.

We don't have a reliable way to know when transports are started since
their start is being performed in a separate goroutine:
927dbb6dc4/pkg/network/server.go (L297-L299)
And transports start is not connected with main server routine, thus,
just wait for some time for the transports goroutine to be started.
Also wait for the peer to be properly registered.

Do not wait until wsReader routine gracefully finishes its work before
WS connection close. Instead, firstly close the connection, and after
that wait for proper wsReader exit.
It's a harsh way, but I don't have any other options to try, because
wsReader routine hangs on `ws.ReadMessage()` operation for more than
ReadDeadline (more than 5 seconds) during test cleanup which results in
the test timeout.

Close#2956. The failure reason is similar to the one described in #3396
for TestNotary: Blockchain's notificationDispatcher is listening to
block events from storeBlock via separate channel. By the moment single
block addition is finished, notification may or may not be properly
handled by notificationDispatcher, especially given the fact that our
runners are slow. As a result, assert.Eventually with 1-second awaiting
period may fail. This issue is solved by adding one more block, because
the second AddBlock finishes only when it sends block addition event to
notificationDispatcher loop, which means that the previous event was
handled.

Made connections in parallel to check the limit and attempt to make one
more connection beyond the limit. Only "default" test case is failing,
because default number of connections is 64 (quite large for slow
runners). The failure reason is:
* given ~1 second for [dealing + request] per connection (time is taken
from the test log)
* by the moment 65-th connection is reached, some connections from the
start of the test have died due to inactivity (this process literally
takes 1 minute)

1. Replace isFinished atomic variable with a channel, no functional changes
here, just use more common way as all our services do.
2. Do not check erors from SetReadDeadline and ReadMessage on exit. It
seems to be not quite right because connection is not closed by this
moment, and thus, these error checks are racy.
3. Add read timeout for the message reader. It is needed because some
tests may leave message unread in the end which results in hanging
test cleanup.
4. Add drain loop to message reader in order not to block WS reader on
sending message.

It's clear that TestBadSubUnsub is hanging on test cleanup, in
particular, on attempt to wait for wsRead routine to exit. The only
place where wsRead routine may hang is sending to msgCh in case if

used when sender is not able to pay the overall transactions fee sum in
the pool (generic -500 error according to the proposal).
