9d6b18adec network: drop minPoolCount magic constant 
We have AttemptConnPeers that is closely related, the more we have there the
bigger the network supposedly is, so it's much better than magic minPoolCount.

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.

Sometimes we already have it, but it's not yet processed, so we can save on
getdata request. It only affects very high-speed networks like 4-1 scenario
and it doesn't affect it a lot, but still we can do it.

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).

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.

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{}.

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

code for this var to be able to call the function as it can have
side-effects. See the example:

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.

We're dealing with a transaction here and it can't be decoded successfully

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).

They were first introduced in a058598ecc and

like they were never used by any external code. This code can be useful on the

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.

0c45ff8f51 rpc: simplify result.Invoke creation, remove needless deps 
Change stack items before marshaling them which makes code in result package
much simpler and not requiring interop, iterator and storage dependencies that
clients shouldn't care about.

This also changes SessionBackedByMPT behavior, now instead of waiting for
traverseiterator call it'll rerun the script immediately if a new session is
created.

not a huge problem).

adab83496c rpc: move Request, Params and related code server-side 
It's absolutely irrelevant for the client and request/response packages should
only contain code that is useful on both sides of the conversation. It's OK
for client tests to reuse this code, but the package is used by external
developers and they shouldn't be bothered with it. Nothing changed
functionally here except WSClient simplification. Fixes #2236.

b5d39a3ffd rpc: add configuration extension for MPT-backed iterator sessions 
Add ability to switch between current blockchain storage and MPT-backed
storage for iterator traversing process. It may be useful because
iterator implementation traverses underlying backed storage (BoltDB,
LevelDB) inside DB's Seek which is blocking operation for BoltDB:
```
Opening a read transaction and a write transaction in the same goroutine
can cause the writer to deadlock because the database periodically needs
to re-mmap itself as it grows and it cannot do that while a read transaction
is open.

If a long running read transaction (for example, a snapshot transaction)
is needed, you might want to set DB.InitialMmapSize to a large enough
value to avoid potential blocking of write transaction.
```

So during bbolt re-mmaping, standard blockchain DB operations (i.e. persist)
can be blocked until iterator resourses release. The described behaviour
is tested and confirmed on four-nodes privnet with BoltDB and
`SessionExpirationTime` set to be 180 seconds. After new iterator session
is added to the server, the subsequent persist took ~5m21s, see the log
record `2022-06-17T18:58:21.563+0300`:

ec3d1fae59 compiler: allow to find appropriate methods via selectors 
c.funcs contains function names using base types, while methods can be defined
on pointers and the value returned from c.getFuncNameFromSelector will have an
asterisk. We can't have the same name used for (*T) and (T) methods, so just
stripping the asterisk allows to get the right one.

b57dd2cad6 compiler: properly inline methods, use receiver 
Notice that this doesn't differentiate between (*T) and (T) receivers always
treating them as is. But we have the same problem with arguments now and the
number of inlined calls is limited, usually we want this behavior.

6014dd720f compiler: don't push X onto the stack for inlined method calls 
Regular methods need this, because it'll be packed into parameters, but
inlined ones should deal with it in inlining code itself because method
receiver will be some local (aliased) variable anyway.

0da0bb21ee rpc: make getnextvalidators behavior compliant with C# node 
Turns out, our getnextvalidators implementation already works the way
getcandidates is supposed to work, but original getnextvalidators works a bit
differently. It only returns validators, it doesn't return Active flag (all
of them are active) and it represents votes as a number. So for the maximum
compatibility:
 * drop non-validator keys from getnextvalidators server-side
 * drop Active flag client-side (sorry, it doesn't exist)
 * allow unmarshalling old answers along with the new one

This technically breaks `query candidates` CLI command, but it'll be fixed
when getcandidates are to be introduced.
