# Changelog
|
|
|
|
This document outlines major changes between releases.
|
|
|
|
## 0.51.0 "Confirmation" (17 Oct 2019)
|
|
|
|
With over a 100 commits made since 0.50.0 release 0.51.0 brings with it full
|
|
block verification, improved and fixed transaction verifications,
|
|
implementation of most of interop functions and VM improvements. Block
|
|
verification is an important milestone on the road to full consensus node
|
|
support and it required implementing a lot of other associated functionality.
|
|
|
|
New features:
|
|
* CHECKSIG, VERIFY and CHECKMULTISIG instructions in VM (#269)
|
|
* witness verification logic for transactions (#368)
|
|
* NEWMAP, HASKEY, KEYS and VALUES instructions, support for Map type in
|
|
PICKITEM, SETITEM, REMOVE, EQUAL, ARRAYSIZE (#359)
|
|
* configurable transaction verification on block addition (#415, #418)
|
|
* contract storage and support for VM to call contracts via APPCALL/TAILCALL
|
|
(#417)
|
|
* support for Interop type in VM (#417)
|
|
* VM now has stepInto/stepOver/stepOut method implementations for debugging
|
|
matching neo-vm behavior (#187)
|
|
* storage support for contracts (#418)
|
|
* added around 90% of interop functions (#418)
|
|
* Invocation TX processing now really does invoke contracts using internal VM
|
|
(#418)
|
|
* blocks are now completely verified when added to the chain (if not
|
|
configured otherwise; #12, #418)
|
|
|
|
Behavior changes:
|
|
* full block verification is now enabled for all network types
|
|
* block's transaction verification enabled for privnet setups, mainnet and
|
|
testnet don't have it enabled
|
|
|
|
Technical improvements:
|
|
* GetVarIntSize and GetVarStringSize were removed from the io package (use
|
|
GetVarSize instead; #408)
|
|
* OVER implementation was optimized to not pop the top element from the stack
|
|
(#406, part of #196 work)
|
|
* vm.VM was extended with HasFailed() method to check its state (previously
|
|
external VM users couldn't do it; #411)
|
|
* redesigned input block queue mechanism, now it's completely moved out of
|
|
the Blockchain, which only accepts the next block via AddBlock() (#414)
|
|
* unpersisted blocks are now fully available with the Blockchain (thus we
|
|
have symmetry now in AddBlock/GetBlock APIs; #414, #366)
|
|
* removed duplicating batch structures from BoltDB and Redis code, now all of
|
|
them use the same batch as MemoryStore does (#414)
|
|
* MemoryStore was exporting its mutex for no good reason, now it's hidden
|
|
(#414)
|
|
* storage layer now returns ErrKeyNotFound for all DBs in appropriate
|
|
situations (#414)
|
|
* VM's PopResult() now doesn't panic if there is no result (#417)
|
|
* VM's Element now has a Value() method to quickly get the item value (#417)
|
|
* VM's stack PushVal() method now accepts uint8/16/32/64 (#417, #418)
|
|
* VM's Element now has TryBool() method similar to Bool(), but without a
|
|
panic (for external VM users; #417)
|
|
* VM has now completely separated instruction read and execution phases
|
|
(#417)
|
|
* Store interface now has Delete method (#418)
|
|
* Store tests were reimplemented to use one test set for all Store
|
|
implementations, including LevelDB that was not tested at all previously
|
|
(#418)
|
|
* Batch interface doesn't have Len method now as it's not used at all (#418)
|
|
* New*FromRawBytes functions were renamed to New*FromASN1 in the keys
|
|
package, previous naming made it easy to confuse them with functions
|
|
operating with NEO serialization format (#418)
|
|
* PublicKey's IsInfinity method is exported now (#418)
|
|
* smartcontract package now has CreateSignatureRedeemScript() matching C#
|
|
code (#418)
|
|
* vm package now has helper functions
|
|
IsSignatureContract/IsMultiSigContract/IsStandardContract matching C# code
|
|
(#418)
|
|
* Blockchain's GetBlock() now returns full block with transactions (#418)
|
|
* Block's Verify() was changed to return specific error (#418)
|
|
* Blockchain's GetTransationResults was renamed into GetTransactionResults
|
|
(#418)
|
|
* Blockchainer interface was extended with GetUnspentCoinState,
|
|
GetContractState and GetScriptHashesForVerifying methods (#418)
|
|
* introduced generic MemCacheStore that is used now for write caching
|
|
(including temporary stores for transaction processing) and batched
|
|
persistence (#425)
|
|
|
|
Bugs fixed:
|
|
* useless persistence failure message printed with no error (#409)
|
|
* persistence error message being printed twice (#409)
|
|
* segmentation fault upon receival of message that is not currently handled
|
|
properly (like "consensus" message; #409)
|
|
* BoltDB's Put for a batch wasn't copying data which could lead to data
|
|
corruption (#409)
|
|
* APPEND instruction applied to struct element was not copying it like neo-vm
|
|
does (#405, part of #196 work)
|
|
* EQUAL instruction was comparing array contents, while it should've compared
|
|
references (#405, part of #196 work)
|
|
* SUBSTR instruction was failing for out of bounds length parameters while it
|
|
should've truncated them to string length (#406, part of #196 work)
|
|
* SHL and SHR implementations had no limits, neo-vm restricts them to
|
|
-256/+256 (#406, part of #196 work)
|
|
* minor VM state mismatches with neo-vm on failures (#405, #406)
|
|
* deadlock on Blockchain init when headers pointer is not in sync with the
|
|
hashes list (#414)
|
|
* node failed to request blocks when headers list was exactly one position
|
|
ahead of block count (#414)
|
|
* TestRPC/getassetstate_positive failed occasionally (#410)
|
|
* panic on block verification with no transactions inside (#415)
|
|
* DutyFlag check in GetScriptHashesForVerifying was not done correctly (#415)
|
|
* default asset expiration for assets created with Register TX was wrong, now
|
|
it matches C# code (#415)
|
|
* Claim transactions needed specific GetScriptHashesForVerifying logic to
|
|
be verified correctly (#415)
|
|
* VerifyWitnesses wasn't properly sorting hashes and witnesses (#415)
|
|
* transactions referring to two outputs of some other transaction were
|
|
failing to verify (#415)
|
|
* wrong program dumps (#295)
|
|
* potential data race in logging code (#418)
|
|
* bogus port check during handshake (#432)
|
|
* missing max size checks in NEWARRAY, NEWSTRUCT, APPEND, PACK, SETITEM
|
|
(#427, part of #373)

## 0.50.0 "Consolidation" (19 Sep 2019)
|
|
|
|
The first release from the new team focuses on bringing all related
|
|
development effort into one codebase, refactoring things, fixing some
|
|
long-standing bugs and adding new functionality. This release merges two
|
|
radically different development branches --- `dev` and `master` that were
|
|
present in the project (along with all associated pull requests) and also
|
|
brings in changes made to the compiler in the neo-storm project.
|
|
|
|
New features:
|
|
* configurable storage backends supporting LevelDB, in-memory DB (for
|
|
testing) and Redis
|
|
* BoltDB support for storage backend
|
|
* updated and extended interop APIs (thanks to neo-storm)
|
|
|
|
Notable behavior changes:
|
|
* the default configuration for privnet was changed to use ports 20331 and
|
|
20332 so that it doesn't clash with the default dockerized neo-privnet
|
|
setups
|
|
* the default configuration path was changed from `../config` to `./config`,
|
|
at this stage it makes life a bit easier for development, later this will
|
|
be changed to some sane default for production version
|
|
* VM CLI now supports type inference for `run` parameters (you don't need to
|
|
specify types explicitly in most of the cases) and treats `operation`
|
|
parameter as mandatory if anything is passed to `run`
|
|
|
|
VM improvements:
|
|
* added implementation for `EQUAL`, `NZ`, `PICK`, `TUCK`, `XDROP`, `INVERT`,
|
|
`CAT`, `SUBSTR`, `LEFT`, `RIGHT`, `UNPACK`, `REVERSE`, `REMOVE`
|
|
* expanded tests
|
|
* better error messages for different erroneous code
|
|
* implemented item conversions following neo-vm behavior: array to/from
|
|
struct, bigint to/from boolean, anything to bytearray and anything to
|
|
boolean
|
|
* improved compatibility with neo-vm (#394)
|
|
|
|
Technical improvements:
|
|
* switched to Go 1.12+
|
|
* gofmt, golint (#213)
|
|
* fixed and improved CircleCI builds
|
|
* removed internal rfc6969 package (#285)
|
|
* refactored util/crypto/io packages, removed a lot of duplicating code
|
|
* updated READMEs and user-level documents
|
|
* update Makefile with useful targets
|
|
* dropped internal base58 implementation (#355)
|
|
* updated default seed lists for mainnet and testnet from neo-cli
|
|
|
|
Bugs fixed:
|
|
* a lot of compiler fixes from neo-storm
|
|
* data access race in memory-backed storage backend (#313)
|
|
* wrong comparison opcode emitted by compiler (#294)
|
|
* decoding error in `publish` transactions (#179)
|
|
* decoding error in `invocation` transactions (#173)
|
|
* panic in `state` transaction decoding
|
|
* double VM run from CLI (#96)
|
|
* non-constant time crypto (#245)
|
|
* APPEND pushed value on the stack and worked for bytearrays (#391)
|
|
* reading overlapping hash blocks from the DB leading to blockchain state
|
|
neo-go couldn't recover from (#393)
|
|
* codegen for `append()` wasn't type-aware and emitted wrong code (#395)
|
|
* node wasn't trying to reconnect to other node if connection failed (#390)
|
|
* stricly follow handshare procedure (#396)
|
|
* leaked connections if disconnect happened before handshake completed (#396)
|
|
|
|
### Inherited unreleased changes
|
|
|
|
Some changes were also done before transition to the new team, highlights are:
|
|
* improved RPC testing
|
|
* implemented `getaccountstate`, `validateaddress`, `getrawtransaction` and
|
|
`sendrawtransaction` RPC methods in server
|
|
* fixed `getaccountstate` RPC implementation
|
|
* implemented graceful blockchain shutdown with proper DB closing
|
|
|
|
## 0.45.14 (not really released, 05 Dec 2018)
|
|
|
|
This one can technically be found in the git history and attributed to commit
|
|
fa1da2cb917cf4dfccbe49d44c5741eec0e0bb65, but it has no tag in the repository
|
|
and so can't count as a properly released thing. Still it can be marked as a
|
|
point in history with the following changes relative to 0.44.10:
|
|
* switched to Go modules for dependency management
|
|
* various optimizations for basic structures like Uin160/Uint256/Fixed8
|
|
* improved testing
|
|
* added support for `invoke` method in RPC client
|
|
* implemented `getassetstate` in RPC server
|
|
* fixed NEP2Encrypt and added tests
|
|
* added `NewPrivateKeyFromRawBytes` function to the `wallet` package
|
|
|
|
## 0.44.10 (27 Sep 2018)
|
|
|
|
This is the last one tagged in the repository, so it's considered as the last
|
|
one properly released before 0.50+. Releases up to 0.44.10 seem to be made in
|
|
automated fashion and you can find their [changes on
|
|
GitHub](https://github.com/nspcc-dev/neo-go/releases).
