A part of integration with NEO Blockchain Toolkit (see #902). To be
able to deploy smart-contract compiled with neo-go compiler via NEO
Express, we have to generate additional .abi.json file. This file
contains the following information:
- hash of the compiled contract
- smart-contract metadata (title, description, version, author,
email, has-storage, has-dynamic-invoke, is-payable)
- smart-contract entry point
- functions
- events
However, this .abi.json file is slightly different from the one,
described in manifest.go, so we have to add auxilaury stractures for
json marshalling. The .abi.json format used by NEO-Express is described
[here](https://github.com/neo-project/neo-devpack-dotnet/blob/master/src/Neo.Compiler.MSIL/FuncExport.cs#L66).
Parsing gas from float value is not always a right idea as
a transform from float is not 1-to-1.
This commit implements Fixed8Flag which parses Fixed8 value from string.
Passing WIF directly in the command line is not something we should be doing.
Also split netfee and sysfee in the RPC as they're different (and add a script
attribute for free transactions).
That's how it was intended to behave originally. One thing questionable here
is contract price (policy thing, basically) being moved to smartcontract
package, but it's probably fine for NEO 2.0 (as it won't change) and we'll
make something better for NEO 3.0.
Right now a bizarre error message can occur if an address flag was not
set: `wallet contains no account for 'AFmseVrdL9f9oyCzZefL9tG6UbvhPbdYzM'`.
This bug is 10x worse if it occures in `transfer` --from flag.
Implement ability to sign transactions with multisig address.
This should be done in several steps:
1. Create TX with `wallet transfer --out <file>`
2. Sign TX with `wallet multisign sign --in <file> --out <file2>`.
3. Repeat 2 for every party.
Input file contains transaction with possibly incomplete
set of the signatures. Output file will contain the same tx
with updated signature set.
When --rpc flag is provided, result transaction is sent
via `sendrawtransaction`.
GAS can be claimed via `wallet claim` command.
This will claim first get all claimable outputs via
`getclaimable` RPC and then form a transaction signed
byte the private key from the wallet.
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
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.
