v0.10.0

[0.10] (October 16th, 2021)

Breaking Changes

• BREAKING: We started adding an initial context.Context to all interruptible functions. All method performing an HTTP call have the new parameter as well as a bunch of other method. We cannot list all of them. If the caller already have a context.Context value, pass it to the function that now require one. Otherwise, simply pass context.Background().

• BREAKING: Fixed binary unpacking of BlockState, TransactionTrace, SignedTransaction, Action (and some inner types). This required changing a few struct fields to better fit with EOSIO definition, here the full list:

  • MerkleRoot.ActiveNodes is now a []Checksum256, was previously []string

  • MerkleRoot.NodeCount is now a uint64, was previously uint32

  • Type EOSNameOrUint32 has been removed and replaced by PairAccountNameBlockNum which is strictly typed now.

  • BlockState.ProducerToLastProduced is now []PairAccountNameBlockNum, was previously [][2]EOSNameOrUint32.

  • BlockState.ProducerToLastImpliedIRB is now []PairAccountNameBlockNum, was previously [][2]EOSNameOrUint32.

  • BlockState.BlockID is now a Checksum256, was previously string.

  • BlockState.ActivatedProtocolFeatures is now a *ProtocolFeatureActivationSet, was previously map[string][]HexBytes.

  • BlockState.ConfirmCount is now a []uint8, was previously []uint32.

  • PendingSchedule.ScheduleHash is now a Checksum256, was previously HexBytes.

  • ActionTraceReceipt.ActionDigest is now a Checksum256, was previously string.

  • ActionTraceReceipt.CodeSequence is now a Varuint32, was previously Uint64.

  • ActionTraceReceipt.ABISequence is now a Varuint32, was previously Uint64.

  • ActionTrace.ActionOrdinal is now a Varuint32, was previously uint32.

  • ActionTrace.CreatorActionOrdinal is now a Varuint32, was previously uint32.

  • ActionTrace.ClosestUnnotifiedAncestorActionOrdinal is now a Varuint32, was previously uint32.

  • Except.Code is now a Int64, was previously int.

  • ExceptLogContext.Level is now a ExceptLogLevel, was previously string.

  • ExceptLogContext.Line is now a uint64, was previously int.

    Note While those are flagged as breaking change to augment the visibility, they are really bug fixes to fit with the behavior of nodeos directly.

• BREAKING: The decoding for ABI variant was not returning the correct json representation. Now ABI variant is returned as a two elements array, the first element being the variant type name as a string and the second the actual value as JSON. For example, assuming a variant type defined as game_type: ["string", "uint32"], and a field of type game_type, before, the JSON serialization would have looked like {"field":"some_string"} or {"field":100} while after the change, it will get serialized to the correct form {"field":["string", "some_string"]} or {"field":["uint32", 100]}.

  Note While this is flagged as breaking change to augment the visibility, this is really a bug fix to fit with the behavior of nodeos directly.

• BREAKING: The serialization for ExtendedAsset was aligned with the eos codebase. Beforehand, it would serialize the field name "Contract" with a capital C, and the Asset field as "asset" where it should have been "quantity".

• BREAKING: Renamed ConsoleLog to SafeString for better re-usability in the codebase.

Added

• Proper handling for float precision in binary encoding/decoding.
• Added SHiP binary structures
• Added capabilities to read EOSIO Snapshot format (early implementation)
• Added architecture to support binary decoding/encoding Variant objects, see []
• Greatly improved performance of NameToString (~230%) method.
• TimePoint will decode with 0 nanoseconds, when the fitNodeos flag is set on the ABI.
• Ability to decode a int128 and uint128 in decimal format when fitNodeos flag is set on the ABI
• Ability to decode nested arrays in ABI decoder.
• Added BlockState.Header field of type SignedBlockHeader that was previously missing from the struct definition.
• Added BlockState.AdditionalSignatures field of type []ecc.Signature that was previously missing from the struct definition.
• Added ActionTrace.ContextFree field of type bool that was previously missing from the struct definition.
• Normalized all logging to use streamingfast/logging and its trace enabled support.

Changed

• All errors are wrapped using fmt.Errorf("...: %w", ..., err) which is standard now in Go.

Fixed

• Optional encoding of primitive types.

  A struct with a non-pointer type tagged with eos:"optional" is now properly encoded at the binary level. Important that means that for non-pointer type, when the value of the type is the "emtpy" value according to Golang rules, it will be written as not-present at the binary level. If it's something that you do want want, use a pointer to a primitive type. It's actually a good habit to use a pointer type for "optional" element anyway, to increase awarness.

• Fix json tags for delegatebw action data.

• Unpacking binary Except now correctly works.

• Unpacking binary Action and ActionTrace now correctly works.

• Unpacking binary TransactionTrace now correctly works.

• Unpacking binary TransactionReceipt type will now correctly set the inner TransactionWithID.ID field correctly.

• Unpacking binary BlockState now correctly works but is restricted to EOSIO 2.0.x version.

Deprecated

• Renamed AccountRAMDelta to AccountDelta which is the correct name in EOSIO.
• Renamed JSONFloat64 to Float64, to follow the same convention that was changed years ago with Uint64, etc. Type alias left for backwards compatibility.

EOSIO 2.0

This release add support for ESIO 2.0 features, mainly WebAuthN keys support (no signing though) and WTMSIG_BLOCK_SIGNATURES protocol feature that brings incompatibilities in the model layer when activated.

The v0.9.0 release add supports for that. We had to break compatibility of the type and field names in some base model present in the library. This was the occasion to make other "small" removal of some types that are not required anymore with the some small API changes of the EOSIO binary format decoder. Expect more structural changes to come in this area.

We renamed all fields that require logic changes from your code so you know quickly due to compilation errors that you need to handle some fields differently now.

Some fields were renamed and deprecated also, see Deprecation Notices section for further details.

WebAuthN Keys

The ecc package has been upgraded to support WebAuthN key in EOSIO model. This supports add the following things:

• A new CurveID of type WA
• Support for PUB_WA_ keys from EOSIO
• Support for SIG_WA_ keys from EOSIO
• Reconstruction of PUB_WA_ format to ecdsa.PublicKey (recovery of Y curve point from compressed PUB_WA_ public key form).
• Verification of payload signature signed with with WA key (this is untested yet, but code is present).

WTMSIG_BLOCK_SIGNATURES Models

We now support all the models updates required for WTMSIG_BLOCK_SIGNATURES protocol.

Breaking Changes

WTMSIG_BLOCK_SIGNATURES changes

The WTMSIG_BLOCK_SIGNATURES enable block to be signed by more than a single key. When this protocol feature is activated, the block can be signed by multiple key, using a key with some weights and a threshold to reach, must like standard EOS permission.

This means that once activated, models for block signing and schedule are now different to support the new feature.

Here the list of changes that occurred, usually, more explanation can be found in the eos-go#p2ptypes.go file directly.

BlockSigningKey in BlockState has been renamed to BlockSigningKeyV1 and now a *ecc.PublicKey

This field can now be nil, which is the case after WTMSIG_BLOCK_SIGNATURES activation.

blockState.BlockSigningKey

now

if blockState.BlockSigningKeyV1 != nil {
  // Deal with EOSIO 1.x model
  ...
}

ValidBlockSigningAuthorityV2 has been added to BlockState

This replaces old BlockSigningKey and is of type BlockSigningAuthority.

ActiveSchedule in BlockState is now of type *ProducerScheduleOrAuthoritySchedule

This new type contains both a V1 field (of type ProducerSchedule) and a V2 field (of type ProducerAuthoritySchedule). Old code that rely on ActiveSchedule now must deal with either ActiveSchedule.V1 (old format) or ActiveSchedule.V2 (new format)

Important There is an ambiguity when deciding about the type the field active_schedule can take since structure can be identical: {version:0, producers:[]} and {version:0,producers:[]}. This means both V1 and V2 field can be present at the same time. This is not a problem when serializing back to JSON since they represent the same JSON, but something you must be aware when doing your conditions around this new type as V1 != nil && V2 != nil == true in some circumstances. The value could be discriminated by checking if ActivatedProtocolFeatures contains the correct feature, it's something we suggest implementer to do in their own code for now, but it's in discussion for a direct usage in eos-go library.

blockState.ActiveSchedule

now

if blockState.ActiveSchedule.V1 != nil {
  // Old format model or indistinguishable from `ProducerAuthoritySchedule`
}

if blockState.ActivateSchedule.V2 != nil {
  // New format model or indistinguishable from `ProducerAuthoritySchedule`
}

PendingSchedule.Schedule is now of type *ProducerScheduleOrAuthoritySchedule

Same logic as ActiveProducer changes above, but apply to the PendingSchedule type.

BlockHeader NewProducers has been renamed NewProducersV1.

EOSIO 2.x does not have this field and has been replaced by a block header extension. Also, we changed how EOSIO binary optional value are handled throughout the library and removed the OptionalProducerSchedule type, you now have a direct ProducerSchedule field instead.

When the WTMSIG_BLOCK_SIGNATURES will be activated, this field will never be populated anymore and must not be used anymore.

The new producers should now be extracted from the BlockHeader.HeaderExtensions field. The library added supported for some know EOSIO BlockHeaderExtension.

A block header extension contains a payload, when the producer_schedule_change_extension block header extension is present, it means we are dealing with a new set of producers, as such, replacing the old BlockHeader.NewProducers field.

if blockHeader.NewProducers != nil {

}

now

if blockHeader.NewProducersV1 != nil {
  // Old format
}

OR

for _, e := range blockHeader.HeaderExtensions {
	if e.Type == uint16(eos.EOS_ProducerScheduleChangeExtension) {
		extension, err := e.AsBlockHeaderExtension("EOS")
		if err != nil { ... }

                 // New format
		scheduleChange := extension.(*eos.ProducerScheduleChangeExtension)
		scheduleChange.Version
		scheduleChange.Producers
	}
}

Removal of GoAwayCrazy enum for GoAwayReason type

This field was not defined in EOSIO software, as such, it was removed. If you were relying on this field to be set, you will need to adapt your code to use another one.

Deprecation Notices

Those field were renamed to be in sync with other Golang fields. You should simply use the new field name. Those will be removed in a next major bump.
