e8d2277fe5 contract/vm: only push NULL after call in dynamic contexts 
And determine the need for Null dynamically. For some reason the only dynamic
context is Contract.Call. CALLT is not dynamic and neither is a call from
native contract, go figure...

13f5fdbe8a vm: extract shared parts of the Context 
Local calls reuse them, cross-contract calls create new ones. This allows to
avoid some allocations and use a little less memory.

2adcf406d3 cli: reload Oracle service on USR1 
Which allows to enable/disable the service, change nodes, keys and other

store a pointer there that can point to nil interface.

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

7c48edaccb core, rpc: fix height-related issue of historic call functionality 
Specifying a certain stateroot R as `invoke*historic` RPC-call
parameter, we're willing to perform historic call based on the storage
state of root R. Thus, next block should be of the height h(R)+1. This
allows to use historic functionality for the current blockchain height.

ff75e67610 core: move stateroot tests into services/stateroot 
They test both module and service which is a bit wrong, but separating these
tests will lead to some duplication, so it's OK for now to have them in the
higher-order package (service imports module).

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.

c2b3ee3d8e core: move basic chain creation into a package of its own 
This allows to reuse it across different packages.

testchain can't be used because of circular dependencies.

Init() is not changed except for filepath.Join() use instead of direct string
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.

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)

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.

core: avoid concurrent map iteration and map write during SeekAsync over private MemCachedStore
 2022-05-18 11:36:57 +03:00
Anna Shaleva
b66f666267 core: ensure memcached Seek operation is properly cancelled 
PR #2495 is not enought, the problem is reproduced during dump restore
with the stacktrace attached down below.

The reason is that SeekAsync starts goroutine that performs Seek
operation over private MemCachedStore. The goroutine iterates over
MemCachedStore's map without holding the lock (it's OK, because it's
private), whereas the main thread continues invocation and
performs writes to the same map. To fix that ic.Exec() needs to
wait until all goroutines are properly exited.

7b632c8ee8 core: refactor natives cache 
1. Use layered natives cache. With layered cache the storeblock
process includes the following steps: create a wrapper over
current nativeCache, put changes into upper nativeCache layer,
persist (or discard) changes.
2. Split contract getters to read-only and read-and-change. Read-only
ones doesn't require the copy of an existing nativeCache item.
Read-and-change ones create a copy and after that change the copy.

neo-bench performance is mostly unaffected, ~0.5% for 1-1 test and 4% for
10K-10K test both fall within regular test error range.

Initially I thought of doing it in the next persist cycle, but testing shows

cycle doesn't affect anything.

ad606101c7 storage: add SeekGC interface for GC 
It's very special, single-purpose thing, but it improves cumulative time spent
in GC by ~10% for LevelDB and by ~36% for BoltDB during 1050K mainnet chain
processing. While the overall chain import time doesn't change in any
noticeable way (~1%), I think it's still worth it, for machines with slower
disks the difference might be more noticeable.

a5f8b8870a storage: use Update for changeset processing

423c7883b8 core: implement basic GC for value-based storage scheme 
The key idea here is that even though we can't ensure MPT code won't make the
node active again we can order the changes made to the persistent store in
such a way that it practically doesn't matter. What happens is:
 * after persist if it's time to collect our garbage we do it synchronously
   right in the same thread working the underlying persistent store directly
 * all the other node code doesn't see much of it, it works with bc.dao or
   layers above it
 * if MPT doesn't find some stale deactivated node in the storage it's OK,
   it'll recreate it in bc.dao
 * if MPT finds it and activates it, it's OK too, bc.dao will store it
 * while GC is being performed nothing else changes the persistent store
 * all subsequent bc.dao persists only happen after the GC is completed which
   means that any changes to the (potentially) deleted nodes have a priority,
   it's OK for GC to delete something that'll be recreated with the next
   persist cycle

Otherwise it's a simple scheme with node status/last active height stored in
the value. Preliminary tests show that it works ~18% worse than the simple
KeepOnlyLatest scheme, but this seems to be the best result so far.

Fixes #2095.

c4ee310e85 mpt: modify refcounted storage scheme to make GC possible 
Add "active" flag into the node data and make the remainder modal, for active
nodes it's a reference counter, for inactive ones the deactivation height is
stored.

Technically, refcounted chains storing just one trie don't need a flag, but
it's a bit simpler this way.
