Both verification and invocation scripts need to
be unmarshaled from hex.
Also fix failing RPC tests: block contains non-pointer
`transaction.Witness` field and (*Witness).MarshalJSON method
is not called.
They have it specified right in the transaction. Unfortunately, this little
change rendered invalid our RPC test chain, but I think it became even better
after it, especially given that chain generation is a nice test by itself, so
it should be running as a regular test.
And drop doc.go from server package as it duplicates docs/rpc.md and has no
value of its own (TODO list is managed with GitHub issues, really). Also, RPC
server is not really expected to be used by non-neo-go packages (contrary to
the client).
1) Add marshaller and tests for smartcontract.Parameter
2) Add unmarshaller and tests for missing types of smartcontract.Parameter:
- MapType
- BoolType
Merged two types:
- smartcontract.ParamType
- rpc.StackParamType
into single one:
- smartcontract.ParamType
as they duplicated the functionality.
NOTE: type smartcontract.MapType was added (as in C# implementation).
From now, list of supported smartcontract parameter types:
UnknownType
SignatureType
BoolType
IntegerType
Hash160Type
Hash256Type
ByteArrayType
PublicKeyType
StringType
ArrayType
MapType
InteropInterfaceType
VoidType
Current implementation of short-circuting is just plain wrong
as it uses `last` or `before-last` labels which meaning depend
on context. It doesn't even handle simple assignements like
`a := x == 1 && y == 2`.
This commit makes all jumps in such conditions local
and adds tests.
Closes#699, #700.
Close transport and disconnect peers right in the Shutdown(), so that no new
connections would be accepted and so that all the peers would be disconnected
correctly (avoiding the same deadlock as in e2116e4c3f).
prevHash == input.PrevHash, so make less DB accesses and more real work. Fix
some bugs along the way:
* spentCoins structure may already be present in the DB when persisting TX,
there is nothing wrong with that and we shouldn't overwrite it
* it's only used for NEO and only to check for claim validity. Thus, when
processing claim tx the corresponding spentCoins should always be present
in the DB
Everywhere in this code prevHash == input.PrevHash, thus we can easily move
some common code out of the loop saving on DB accesses and
serialization/deserialization.
sendrawtransaction just returns a bool, sendtoaddress returns a proper
transaction and that should be the same as the one we have in
TransactionOutputRaw.
Mostly as is, no real effort done yet to optimize them, so there are still a
lot of duplicates there, but at least we sort them out into different smaller
packages.
Implement mempool and consensus block creation policies, almost the same as
SimplePolicy plugin for C# node provides with two caveats:
* HighPriorityTxType is not configured and hardcoded to ClaimType
* BlockedAccounts are not supported
Other than that it allows us to run successfuly as testnet CN, previously our
proposals were rejected because we were proposing blocks with oversized
transactions (that are rejected by PoolTx() now).
Mainnet and testnet configuration files are updated accordingly, but privnet
is left as is with no limits.
Configuration is currently attached to the Blockchain and so is the code that
does policying, it may be moved somewhere in the future, but it works for
now.
Both are very useful outside of the core, this change also makes respective
transactions initialize with the package as they don't depend on any kind of
input and it makes no sense recreating them again and again on every use.
It wasn't sorted when all validators were elected. There is also no need to do
`Unique()` on the result because validators are distinguished by the key, so
no two registered validators can have the same key.
Changed returncode of getrowtransaction method in case when transaction
with specified hash does not exists. Now it returns error with code -100
instead of -32602 (as in c# node)
- Attribute should have 2 fields (usage, data)
- VOut should have 4 (5) fields (asset, value, address, n)
- Script should have 2 fields (invocation, verification)
As C# node does it. Technically it's only needed for consensus and could be
implemented in the appropriate package, but for better compatibility with C#
node we're better returning it sorted right here.
We can still lock the (*Server).run with dead peers:

The problem is that the select in putPacketIntoQueue() only works the way it
was intended to after the `close(p.done)`, but that happens only after
successful unregistration request send. Thus, do disconnects the other way
around, first unblock queueing and exit goroutines, then destroy the
connection (if it wasn't previously destroyed) and only after that signal to
the Server.
