8311bda355 vm: harden LEFT and RIGHT implementations against negative indexes 2019-09-11 14:51:04 +03:00

17f3a21e27 vm: harden SUBSTR implementation against bad index/offset values 
The upper index bound for slices is capacity, not length. Check for negative
values also. Fixes #387.

fc1075bf75 vm: protect PUSHDATA from short reads 
Same thing done in a2a8981979 for PUSHBYTES,
failing to read the amount of bytes specified should lead to FAULT. Also
makes readUint16() and readUint32() panic as this is the behavior we want in
these cases. Add some tests along the way.

5bd666b786 vm: return NOP as current instruction for just loaded VM 
Before:
NEO-GO-VM > loadgo h.go
READY: loaded 16 instructions
NEO-GO-VM > ip
instruction pointer at -1 (PUSH0)

After:
NEO-GO-VM > loadgo h.go
READY: loaded 16 instructions
NEO-GO-VM > ip
instruction pointer at -1 (NOP)

I think NOP is a little less scary.

00a290de07 update minimum supported version of Go to 1.12 
Go 1.11 is not supported upstream and it also breaks our precious VM for some
reason, so use better versions of Go. Fixes #384.

Merge pull request #382 from nspcc-dev/feature/implicit-stackitem-conversion 
VM: implement stack item conversion

Fixes #372.

Also added tests for NOT and SIGN to check new behavior.
Also fixed a bug with Bool casting: it should be != 0 instead of == 1.

7b0c2781d2 vm: expand instruction list with commands from current VM spec 
Current NEO documentation lists them:
https://docs.neo.org/docs/en-us/tooldev/advanced/neo_vm.html

CALL_* instructions were left out because of conflict with golint (but they're
removed in NEO 3.0 anyway, so wasting time on them makes no sense).

Update autogenerated instruction_string.go accordingly.

d4d1c79546 _pkg.dev: drop vm 
This is a nice VM, it has an interesting stack items model, better separation
of elements from stack implementation, simpler stack implementation and a bit
nicer opcode implementation mechanism. At the same time it lacks so many
features and is so differing from our current VM (that is closely tied to the
compiler) that it makes its code very hard to reuse for master's VM
improvement.

Also, some differences are non-obvious to judge in terms of better or
worse. Stack item model seems to be more extensible, but at the same time we
know very well what kind of stack items we have and this doesn't change a
lot. Slice-based stack is simple but it's hard to say which one would perform
better for real-world smart contracts (it has different tradeoffs in
operations complexity).

Based on that, I'm dropping it. Some ideas will be reused during VM
refactoring, but no more than that. Refs. #307.
