1. Initialization is performed via `Blockchain` methods.
2. Native Oracle contract updates list of oracle nodes
and in-fly requests in `PostPersist`.
3. RPC uses Oracle module directly.
If port is dynamically allocated, `(*Server).Addr` will contain
0 port. This commit executes listener before exiting from `Start()`
and sets Addr to the actual address.
It's not needed any more with Go 1.13 as we have wrapping/unwrapping in base
packages. All errors.Wrap calls are replaced with fmt.Errorf, some strings are
improved along the way.
We make it explicit in the appropriate Block/Transaction structures, not via a
singleton as C# node does. I think this approach has a bit more potential and
allows better packages reuse for different purposes.
Given `-s 1` with a dump of 6001 blocks it skipped the first one and then
tried to import the next 6001 which failed with EOF because there are only
6000 blocks left.
NGD dumps are all zero-based and even though I don't like it (genesys block
should not be imported, it's the root of chain trust), we have to conform to
this convention for interoperability with C# nodes (otherwise they're not able
to import our dumps).
This also renames `skip` dumper parameter to `start` which is more logical
now, the default is to start the dump from block number zero.
This seriously improves the serialization/deserialization performance for
several reasons:
* no time spent in `binary` reflection
* no memory allocations being made on every read/write
* uses fast ReadBytes everywhere it's appropriate
It also makes Fixed8 Serializable just for convenience.
This one enables our RPC to be called from the browser if there is a
need. It's insecure and not standards-compliant, thus this behaviour is
configurable is not enabled by default. It makes our node with this workaround
enabled compatible with neo-mon monitoring.
Originally debugged by @anatoly-bogatyrev in #464.
add close function to storage interface
add common defer function call which will close db connection
remove context as soon as it's not needed anymore
updated unit tests
* Fixed small incosistencies related to comments and variable name
* For testing purposes we have to move the method newBlockchain from the cli/server/server.go to pkg/core/blockchain.go. In addition we have to rename it to NewBlockchainLevelDB in order to be able to export it and avoid naming conflicts. In future we still need to think how to switch between different blockchain implementation easily but for the time being this is not possible.
* Added unit tests for the rpc server
* Added unit_testnet chain fixture
* fixed port number
* Added errors handling
* move unit_testnet chain from 'cli/chains' to 'pkg/rpc/chains'
