This solves two problems:
* adds support for shortened SYSCALL form that uses IDs (similar to #434, but
for NEO 2.0, supporting both forms), which is important for compatibility
with C# node and mainnet chain that uses it from some height
* reworks interop plugging to use callbacks rather than appending to the map,
these map mangling functions are clearly visible in the VM profiling
statistics and we want spawning a VM to be fast, so it makes sense
optimizing it. This change moves most of the work to the init() phase
making VM setup cheaper.
Caveats:
* InteropNameToID accepts `[]byte` because that's the thing we have in
SYSCALL processing and that's the most often usecase for it, it leads to
some conversions in other places but that's acceptable because those are
either tests or init()
* three getInterop functions are: `getDefaultVMInterop`, `getSystemInterop`
and `getNeoInterop`
Our 100K (1.4M->1.5M) block import time improves by ~4% with this change.
VM should be responsible for code execution and in case anyone interested in additional logging or errors they could handle them like we do it iin cli.
Fixes things like:
* exported type/method/function X should have comment or be unexported
* comment on exported type/method/function X should be of the form "X ..."
(with optional leading article)
Refs. #213.
neo-storm has developed more wrappers for syscall APIs, so they can and should
be used as a drop-in replacement for pkg/vm/api. Moving it out of vm, as it's
not exactly related to the VM itself.
* Initial draft of the ICO template ported from NEX.
* filled in token configuration
* added kyc storage prefix
* fixed byte array conversion + added tests
* fixed broken test + made 1 file for the token sale example.
* implemented the NEP5 handlers
* bumped version
* support VM to pass method and arguments to a script.
* added support for type assertions in smartcontracts.
* added native vm support for print.
* moved VM API packages to vm -> API
* reverted the native Print opcode in favor of runtime.Log
* added support for registering custom interop hooks in the VM.
* Updated README
* Updated compiler with @OPTIMIZE tags
* Moved more tests to VM package.
* optimized and refactored compiler and vm API
* updated README with new smartcontract apis
* bumped version
* renamed test folders and fixed bug where wrong jump labels would be exectuted for rewrite.
* Added support for Osize (len(string)) and factored out the array tests
* Added current instruction number to VM prompt if program is loaded.
* added support for unary expressions.
* updated README of and sorted the help commands
* updated readme of the compiler
* bumped version -> 0.39.0
