NOT is 1 byte shorter and 2048 times cheaper than CONVERT. Inspired by
neo-project/neo-vm#493.

28f54d352a network: do getaddr requests periodically, fix #2745
Every 1000 blocks seems to be OK for big networks (that only had done some
initial requests previously and then effectively never requested addresses
again because there was a sufficient number of addresses), won't hurt smaller
ones as well (that effectively keep doing this on every connect/disconnect,
peer changes are very rare there, but when they happen we want to have some
quick reaction to these changes).

9efc110058 network: it is 42
32 is a very good number, but we all know 42 is a better one. And it can even
be proven by tests with higher peaking TPS values.

You may wonder why is it so good? Because we're using packet-switching
networks mostly and a packet is a packet almost irrespectively of how bit it
is. Yet a packet has some maximum possible size (hi, MTU) and this size most
of the time is 1500 (or a little less than that, hi VPN). Subtract IP header
(20 for IPv4 or 40 for IPv6 not counting options), TCP header (another 20) and
Neo message/payload headers (~8 for this case) and we have just a little more
than 1400 bytes for our dear hashes. Which means that in a single packet most
of the time we can have 42-44 of them, maybe 45. Choosing between these
numbers is not hard then.

We have AttemptConnPeers that is closely related, the more we have there the

0c3b03617e core: optimize HasBlock check for recent blocks
When block is being spread through the network we can get a lot of invs with
the same hash. Some more stale nodes may also announce previous or some
earlier block. We can avoid full DB lookup for them and minimize inv handling
time (timeouts in inv handler had happened in #2744).

It doesn't affect tests, just makes node a little less likely to spend some
considerable amount of time in the inv handler.

cfb5058018 network: batch getdata replies
This is not exactly the protocol-level batching as was tried in #1770 and
proposed by neo-project/neo#2365, but it's a TCP-level change in that we now
Write() a set of messages and given that Go sets up TCP sockets with
TCP_NODELAY by default this is a substantial change, we have less packets
generated with the same amount of data. It doesn't change anything on properly
connected networks, but the ones with delays benefit from it a lot.

This also improves queueing because we no longer generate 32 messages to
deliver on transaction's GetData, it's just one stream of bytes with 32
messages inside.

Do the same with GetBlocksByIndex, we can have a lot of messages there too.

But don't forget about potential peer DoS attacks, if a peer is to request a
lot of big blocks we need to flush them before we process the whole set.

e1b5ac9b81 network: separate tx handling from msg handling
This allows to naturally scale transaction processing if we have some peer
that is sending a lot of them while others are mostly silent. It also can help
somewhat in the event we have 50 peers that all send transactions. 4+1
scenario benefits a lot from it, while 7+2 slows down a little. Delayed
scenarios don't care.

Surprisingly, this also makes disconnects (#2744) much more rare, 4-node
scenario almost never sees it now. Most probably this is the case where peers
affect each other a lot, single-threaded transaction receiver can be slow
enough to trigger some timeout in getdata handler of its peer (because it
tries to push a number of replies).

It makes sense in general (further narrowing down the time window when

4dd3fd4ac0 network: only call tx callback if we're waiting for transactions
Until the consensus process starts for a new block and until it really needs
some transactions we can spare some cycles by not delivering transactions to
it. In tests this doesn't affect TPS, but makes block delays a bit more
stable. Related to #2744, I think it also may cause timeouts during
transaction processing (waiting on the consensus process channel while it does
something dBFT-related).

e80c60a3b9 network: rework broadcast logic
We have a number of queues for different purposes:
 * regular broadcast queue
 * direct p2p queue
 * high-priority queue

And two basic egress scenarios:
 * direct p2p messages (replies to requests in Server's handle* methods)
 * broadcasted messages

Low priority broadcasted messages:
 * transaction inventories
 * block inventories
 * notary inventories
 * non-consensus extensibles

High-priority broadcasted messages:
 * consensus extensibles
 * getdata transaction requests from consensus process
 * getaddr requests

P2P messages are a bit more complicated, most of the time they use p2p queue,
but extensible message requests/replies use HP queue.

Server's handle* code is run from Peer's handleIncoming, every peer has this
thread that handles incoming messages. When working with the peer it's
important to reply to requests and blocking this thread until we send (queue)
a reply is fine, if the peer is slow we just won't get anything new from
it. The queue used is irrelevant wrt this issue.

Broadcasted messages are radically different, we want them to be delivered to
many peers, but we don't care about specific ones. If it's delivered to 2/3 of
the peers we're fine, if it's delivered to more of them --- it's not an
issue. But doing this fairly is not an easy thing, current code tries performing
unblocked sends and if this doesn't yield enough results it then blocks (but
has a timeout, we can't wait indefinitely). But it does so in sequential
manner, once the peer is chosen the code will wait for it (and only it) until
timeout happens.

What can be done instead is an attempt to push the message to all of the peers
simultaneously (or close to that). If they all deliver --- OK, if some block
and wait then we can wait until _any_ of them pushes the message through (or
global timeout happens, we still can't wait forever). If we have enough
deliveries then we can cancel pending ones and it's again not an error if
these canceled threads still do their job.

This makes the system more dynamic and adds some substantial processing
overhead, but it's a networking code, any of this overhead is much lower than
the actual packet delivery time. It also allows to spread the load more
fairly, if there is any spare queue it'll get the packet and release the
broadcaster. On the next broadcast iteration another peer is more likely to be
chosen just because it didn't get a message previously (and had some time to
deliver already queued messages).

It works perfectly in tests, with optimal networking conditions we have much
better block times and TPS increases by 5-25%% depending on the scenario.

I'd go as far as to say that it fixes the original problem of #2678, because
in this particular scenario we have empty queues in ~100% of the cases and
this new logic will likely lead to 100% fan out in this case (cancelation just
won't happen fast enough). But when the load grows and there is some waiting
in the queue it will optimize out the slowest links.

641abd4d1c smartcontract: fix underlying PublicKey parameter value
Value of PublicKey parameter always stores public key bytes, not the
deserialized representation. All other code (CLI parameters parsing with
its NewParameterFromString, Parameter unmarshaller, etc.) is based on
the idea that value of PublicKey is []byte.

dabdad20ad network: don't wait indefinitely for packet to be sent
Peers can be slow, very slow, slow enough to affect node's regular
operation. We can't wait for them indefinitely, there has to be a timeout for
send operations.

This patch uses TimePerBlock as a reference for its timeout. It's relatively
big and it doesn't affect tests much, 4+1 scenarios tend to perform a little
worse with while 7+2 scenarios work a little better. The difference is in some
percents, but all of these tests easily have 10-15% variations from run to
run.

It's an important step in making our gossip better because we can't have any
behavior where neighbors directly block the node forever, refs. #2678 and

80f71a4e6e compiler: do not enforce variadic event args check on ellipsis usage
In case of ellipsis usage compiler defines argument type as ArrayT
(which is correct, because it's a natural representation of the last
argument, it represents the array of interface{}).
Here goes the problem:
```
=== RUN   TestEventWarnings/variadic_event_args_via_ellipsis
    compiler_test.go:251:
        	Error Trace:	compiler_test.go:251
        	Error:      	Received unexpected error:
        	            	event 'Event' should have 'Integer' as type of 1 parameter, got: Array
        	Test:       	TestEventWarnings/variadic_event_args_via_ellipsis
```

Parsing the last argument in this case is a separate complicated problem
due to the fact that we need to grab types of elements of []interface{} inside the
fully qualified ast node which may looks like:
```
runtime.Notify("Event", (append([]interface{}{1, 2}, (([]interface{}{someVar, 4}))...))...)
```

Temporary solution is to exclude such notifications from analysis until we're
able to properly resolve element types of []interface{}.

We can technically have more signatures in the file than we need and it's OK,
this case should be handled.

800321db06 compiler: rename named unused global vars to "_"
So that (*codegen).Visit is able to omit code generation for these
unused global vars. The most tricky part is to detect unused global
variables, it is done in several steps:
1. Collect the set of named used/unused global vars.
2. Collect the set of globally declared expressions that contain
function calls.
3. Pick up global vars from the set made at step 2.
4. Traverse used functions and puck up those global vars that are used
from these functions.
5. Rename all globals that are presented in the set made at step 1
but are not presented in the set made on step 3 or step 4.

1e6b70d570 compiler: adjust TestInline template
Move all auxiliary function declaration after Main, so that INITSLOT
instructions counter works properly. `vmAndCompileInterop` loads program
and moves nextIP to the Main function offset if there's no _init
function. If _init is there, then nextIP will be moved to the start of
_init. In TestInline we don't handle instructions properly (CALL/JMP
don't change nextIP), we just perform instruction traversal from the
start point via Next(), thus INITSLOT counter value depends on the
starting instruction, which depends on _init presence.

1dcbdb011a compiler: emit code for unnamed global var decls more careful
In case if global var is unnamed (and, as a consequence, unused) and
contains a function call inside its value specification, we need to emit
code for this var to be able to call the function as it can have
side-effects. See the example:
```
package foo

import "github.com/nspcc-dev/neo-go/pkg/interop/runtime"

var A = f()

func Main() int {
   return 3
}

func f() int {
   runtime.Notify("Valuable notification", 1)
   return 2
}
```

8b132cba0c wallet: respect user-locked accounts, don't sign with them
NEP-6 has a notion of locked acccounts and SignTx must respect this user's
choice. For some reason this setting was inappropriately used by our RPC
client tests (probably a different kind of lock was meant).
2022-08-26 18:21:58 +03:00
Roman Khimov
54c5fd61df wallet: make SignTx more precise and accurate
* each account must have an appropriate signer, if there is no signer for
   this account in the tx it's an error
 * we can only safely append to Scripts when account belongs to the next
   signer (we don't have appropriate verification scripts for other signers)
 * when contract has one parameter, the signature shouldn't be appended to
   other data

I think these rules allow to handle more cases and do that safer. We have more
complex scenarios though, like non-signature parameters or mixed-parameter
invocation scripts, but that's out of scope for now.

59fbc689e4 vm/bench: extend refcounter benchmarks
Adding an array multiple times leads to the fast update via `IncRC`.
This hides the allocation that is there on the first addition. In this
commit add another benchmark which measures Add/Remove together, to
ensure that `switch` in `refCounter.Add` is entered. Benchmark results
are meaningful, because `Add`/`Remove` have almost identical implementation.

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.

Solution:

Allow using multi-return function calls as general variable declaration
value. It was supported for assignment statements, so do the same for
*ast.GenDecl if it's a variable under the hood.

5d5455312a rpcclient: add policy package for the PolicyContract contract
And test it with the RPC server.

Notice that getters still return int64 instead of *big.Int, that's because
these values are very limited and technically could even fit into an int (but
that seems to be too dangerous to use for long-term compatibility).

3c5a720e3a smartcontract: drop Params type and TryParse methods
They were first introduced in a058598ecc and
then carefully moved in 648e0bb242, but it looks
like they were never used by any external code. This code can be useful on the
server, but the server has its own params package to deal with
parameters. Clients usually create Parameters and then get results as
stackitem.Items, so they don't use this code either. So there is zero point in
keeping it.
