@taquito/taquito - Add support of failing_noop operation in Contract and Wallet API

Taquito now supports the failing_noop operation

const Tezos = new TezosToolkit(rpcUrl);

Tezos.setWalletProvider(wallet)
const signedW = await Tezos.wallet.signFailingNoop({
arbitrary: char2Bytes("Hello World"),
basedOnBlock: 0,
});

Tezos.setSignerProvider(signer)
const signedC = await Tezos.contract.signFailingNoop({
arbitrary: char2Bytes("Hello World"),
basedOnBlock: 'genesis',
});

@taquito/rpc - Add support of simulateOperation RPC call

const Tezos = new TezosToolkit(rpcUrl)
let account ='tz1...'
let counter = Number((await Tezos.rpc.getContract(account, {block: 'head'})).counter)
const op = {
  chain_id: await Tezos.rpc.getChainId(),
  operation: {
    branch: 'BLzyjjHKEKMULtvkpSHxuZxx6ei6fpntH2BTkYZiLgs8zLVstvX',
    contents: [{
      kind: OpKind.TRANSACTION,
      counter: (counter + 1).toString(),
      source: account,
      destination: account,
      fee: '0',
      gas_limit: '1100',
      storage_limit: '600',
      amount: '1',
    }]
  }
};

let simulate = await Tezos.rpc.simulateOperation(op)).contents[0]

Taquito v17.1.1

Summary

This is a patch release to fix a potential issue with verifySignature() and hex2buf() util method.

Bug Fixes

• Fixed a potentially exploitable behaviour where verifySignature() was allowing an appended character to a message payload and still verify the signature correctly. It has now been fixed to validate against odd length characters #2578

Taquito v17.1.0

Potential Breaking Changes

• Updated RxJS version from v6.6.3 to v7.8.1
• Updated TS version into v4.2.4
• Please be wary due to the RxJS version upgrade, we've been seeing intermittent timeouts when testing against a Flextesa sandbox. This behaviour is not present when using it against a regular node (Mainnet, Nairobinet, etc). We are still investigating what the cause might be. #2261

Some other subtle changes that might affect some developers:

• In @taquito/taquito - IntegerError is renamed to InvalidBalanceError
• In @taquito/taquito - PrepareProvider used to throw RevealEstimateError now will throw PublicKeyNotFoundError
• In @taquito/tzip-16 - MetadataNotFound is renamed to ContractMetadataNotFoundError
• In @taquito/tzip-16 - InvalidMetadata is renamed to InvalidContractMetadataError
• In @taquito/tzip-16 - InvalidMetadataType is renamed to InvalidContractMetadataTypeError
• In @taquito/tzip-16 - BigMapMetadataNotFound is renamed to BigMapContractMetadataNotFoundError
• In @taquito/tzip-16 - UriNotFound is renamed to UriNotFoundError
• In @taquito/tzip-16 - InvalidUri is renamed to InvalidUriError
• In @taquito/tzip-16 - ProtocolNotSupported is renamed to ProtocolNotSupportedError
• In @taquito/tzip-16 - UnconfiguredMetadataProviderError is renamed to UnconfiguredContractMetadataProviderError
• In @taquito/tzip-16 - ForbiddenInstructionInViewCode is renamed to ForbiddenInstructionInViewCodeError

Taquito v16.2.0

Potential Breaking Changes:

• Some error classes may have been moved to the @taquito/core package. Note to developers if they are exporting any error classes to capture errors, there might be a need to adjust the export path.

• We have an ongoing error class refactoring which includes ticket #1992 (create an error class hierarchy), #1993 (consolidate duplicate errors in Taquito) and #1994 (improve error classes in individual packages, namely @taquito/utils, @taquito/local-forging and @taquito/signer). Here are a list of notable changes:

  1. @taquito/sapling Class SaplingToolkit function prepareUnshieldedTransaction used to throw InvalidKeyError now throw a InvalidAddressError instead
  2. @taquito/rpc when validateContractAddress used to throw InvalidAddressError will now throw InvalidContractAddressError.
  3. @taquito/sapling prepareUnshieldedTransaction function when validateDestinationImplicitAddress used to throw InvalidAddressError now throw InvalidKeyHashError
  4. @taquito/local-forging smartRollupAddressDecoder used to throw InvalidAddressError now throw InvalidSmartRollupAddressError
  5. @taquito/local-forging used to have class InvalidSmartRollupContractAddressError now is InvalidSmartRollupCommitmentHashError
  6. @taquito/local-forging function smartRollupContractAddressEncoder rename to smartRollupCommitmentHashEncoder
  7. @taquito/signer PrivateKeyError is replaced by common error InvalidKeyError from @taquito/core

• In @taquito/michelson-encoder we introduced a new semantic { Some: null} to EncodeObject() for nested options type like (option (option nat)). The old semantic still works when making contract calls but will look to deprecated them in the future as table below. And the corresponding Execute() will now return new semantic { Some: 1 } as previously return 1 will be deprecated soon. #2344
  

Note: There are also significant (backwards compatible) changes to the @taquito/taquito package, largely regarding the flow of preparing, estimating, forging, and injecting operations into a node. No breaking changes are expected, but users are welcomed to reach out to the team if any issues arise.

Summary

New Features

• Introduction of the new @taquito/core package, which will contain important types and shared classes #1992

Bug Fixes

• Fixed contract calls with nested option with Some None #2344
• Fixed a broken isNode check that checks whether the runtime environment is a Node environment or not PR#2498

Improvement

• @taquito/taquito - Tweaked the functionality of PrepareProvider to not have coupling with Estimation, it will now output PreparedOperation with default fees, gas limits and, storage limits #2257
• @taquito/taquito - Added a filter for events listener to exclude failed events #2319
• @taquito/utils - Updated address validation to include smart rollup addresses #2444
• Removed duplicate error classes and did a small audit to streamline them across all packages #1993
• Improved error messages and fix relevant error classes in @taquito/local-forging and @taquito/signer #1994

Documentation

• Updated old Michelson code in our smart contract documentation #2482
• Updated README to reference Mumbainet #2459
• Updated wrong example in docs for Tezos domains #2436
• Added extra detail on complex parameter calls in the docs #2443

Internals

• OperationEmitter class in @taquito/taquito have been replaced with PrepareProvider and the Provider abstract class #2257
  • RpcContractProvider, RpcEstimateProvider, RpcBatchProvider, and RpcTzProvider no longer extends OperationEmitter, and is replaced with a more lightweight abstract class Provider #2428, #2429, #2430, #2431
• Removed the dependency axios-fetch-adapter and adapted the code directly into Taquito PR#2457

@taquito/taquito - Added a filter for events listener to exclude failed events

Introduces a new filter excludeFailedOperations to determine whether you'd want to filter out failed events or not

const Tezos = new TezosToolkit(RPC_URL);

Tezos.setStreamProvider(
  Tezos.getFactory(PollingSubscribeProvider)({
    shouldObservableSubscriptionRetry: true, 
    pollingIntervalMilliseconds: 1500 
  })
);

try {
  const sub = Tezos.stream.subscribeEvent({
    tag: 'tagName',
    address: 'KT1_CONTRACT_ADDRESS',
    excludeFailedOperations: true
  });
    
  sub.on('data', console.log);
    
} catch (e) {
  console.log(e);
}

@taquito/taquito - Tweaked the functionality of PrepareProvider

The PrepareProvider is a somewhat new feature to Taquito that allows users to independently create a PreparedOperation object. It's behaviour is slightly changed so that it does not estimate directly when preparing. The estimation and the preparation process are now 2 separate process, removing the circular dependency it used to have.

Taquito v16.1.2

New Feature

v16.1.2 includes the new Beacon SDK 4.0.0. The v4 Beacon SDK ships with substantive changes to the wallet selection modal and to supported transports. The Beacon SDK may introduce some new build issues for Taquito users. Some of these concerns will be addressed in the next Beacon SDK version update.

There are also potential known issues regarding the Kukai wallet connection to ghostnet, but we will continue to be on the lookout for subsequent updates from the Airgap team for the resolution.

Internal Changes

• Update Algolia search indexing workflow for the Taquito website PR #2434

Taquito v16.1.2-beta-RC.0

New Feature

v16.1.2-beta-RC.0 includes the new Beacon SDK 4.0.0. The v4 Beacon SDK ships with substantive changes to the wallet selection modal and to supported transports. The Beacon SDK may introduce some new build issues for Taquito users.

We are now releasing this as a BETA so that eager users can upgrade immediately and cautious users can hold back. We want to hear from any users that have issues with this new Beacon version, particularly regarding build issuer for your project and wallet connection behaviour when you test your project with the popular Tezos Wallets.

We intend to shake out any remaining issues so that our users, and ultimately your users, have a great experience when using Tezos-based projects.

Taquito v16.1.1

Bug Fixes

• Fixed an issue where the package forked from vespaiach/axios-fetch-adapter was not able to be resolved by some package managers. We have since published the fork on NPM as @taquito/axios-fetch-adapter PR #2427
