CHANGELOG.md

Release Notes

All notable changes to this project will be documented in this file.

[1.38.0] – 2022-10-06

New

• Debot module:
  • ABI specification v2.3 is supported in DEngine.
  • Supported flags OVERRIDE_TS, OVERRIDE_EXPT, ASYNC_CALL for external messages in DEngine.

Improvement

• Support cookies in net module for std mode (not wasm)
• Remove network aliases (main, dev, main.ton.dev, net.ton.dev)
• No balancing logic in case of 1 endpoint + removed the check of REMP support on backend during client initialization. These changes will make client initialization faster -> CLI tools that use SDK will work faster, web pages will load initial data faster.
• Changed 401 error message to response message from API
• Tests improvements: cryptobox tests made stable

[1.37.2] – 2022-08-10

New

• crypto.encryption_box_get_info returns nacl box public key in info.public field.
• Gosh instruction are supported in local VM and executor:
  • execute_diff
  • execute_diff_patch_not_quiet
  • execute_zip
  • execute_unzip
  • execute_diff_zip
  • execute_diff_patch_zip_not_quiet
  • execute_diff_patch_quiet
  • execute_diff_patch_zip_quiet
  • execute_diff_patch_binary_not_quiet
  • execute_diff_patch_binary_zip_not_quiet
  • execute_diff_patch_binary_quiet
  • execute_diff_patch_binary_zip_quiet

Improvement

• create_crypto_box optimisation. When a user creates a crypto box, library encrypts provided secret information using provided password and salt. When library encrypts the secret, it calculates encryption key from password and salt using scrypt function which takes a lot of CPU time (about 1 second). So when a user creates many crypto boxes using the same password and salt, it takes a lot of time (about 12 seconds for 10 crypto boxes). With the optimisations introduced in this version the library stores the pair (password+salt => encryption key) in internal cache for approximately 2 seconds. So when a user creates many crypto boxes at a time using the same password and salt, library uses cached information to skip heavy calculations. As a result now it takes only a second to create 10 crypto boxes.

Fixed

• Some enum types were not properly presented in api.json (some types that use serde(content="value"))

[1.37.1] – 2022-08-03

Fixed

• Pinned BOC cache now has reference counter for each pin in BOC. BOC can be pinned several times with the same pin. BOC is removed from cache after all references for all pins are unpinned with cache_unpin function calls.
• Fixed error resolving in case when account state was modified after message expiration time. Now appropriate error text is added to error message instead of executor internal error

[1.37.0] – 2022-07-28

New

• client sends config.network.access_key as Authorization: Basic ... or Authorization: Bearer ... header depending on the value passed: if value is in hex, then it is processed as project secret (basic), if in base64 - then as JWT token (bearer).
• client accepts endpoints with /graphql suffixes specified in config.

Fixed

• Updated zstd in order to fix building.

[1.36.1] – 2022-07-18

Improvement

• Time synchronization check between device and server improved: calculation of time-diff with server is moved from batched query to send_message function and therefore now query execution time does not affect this time diff.

[1.36.0] – 2022-07-01

New

• ABI specification v2.3 is supported
• parameter address is added to abi.encode_message_body function

[1.35.1] – 2022-06-28

Improved

• abi module errors have been improved

[1.35.0] – 2022-06-28

New

• chksig_always_succeed execution option used in params of the tvm.run_get, tvm.run_tvm and tvm.run_executor.
• abi.calc_function_id function
• tokio library is updated to 1.* version

[1.34.3] – 2022-06-08

New

• send accessKey header in api requests (specified in config.network.accessKey)

Fixed

• send headers in info api requests

[1.34.2] – 2022-05-30

Fixed

• build process

[1.34.1] – 2022-05-26

New

• supported removing Copy interface from UInt256
• supported changed interface of ton_types::Cell

[1.34.0] – 2022-05-18

New

• client.config function that returns the current client config

• run_executor().fees is extended with these fields:

  • ext_in_msg_fee - fee for processing external inbound message
  • total_fwd_fees - total fees of action phase
  • account_fees - total fees the account pays for the transaction

• main and dev endpoints aliases for Evernode Cloud Mainnet and Devnet endpoints

Improved

• Added documentation for TransactionFees type (run_executor().fees).
• Documentation now includes enum types descriptions. To achieve it we updated binding-gen: enum of types now produces its own type for each enum variant.

[1.33.1] – 2022-05-10

Fixed

• Websocket errors weren't treated as a network errors. This is why all the processing functions that worked via wss protocol failed on these errors without retries. Now retries are performed.
• SDK tried to rebalance even if only a single endpoint was specified. Now in case of a single endpoint, no rebalancing occurs.

[1.33.0] – 2022-05-02

New

• allow_partial flag in all abi.decode_* functions. This flag controls decoder behaviour whether return error or not in case of incomplete BOC decoding
• REMP supported. ProcessingEvent enum is extended with REMP statuses (enum of events posted into processing.wait_for_transaction function callback )
• UNSTABLE. first_remp_status_timeout and next_remp_status_timeout parameters in network config

[1.32.0] – 2022-03-22

New

• network.queries_protocol config parameter allows selecting protocol the SDK uses to communicaite with GraphQL endpoint:
  • HTTP – SDK performs single HTTP-request for each request.
  • WS – SDK uses single WebSocket connection to send all requests. This protocol is a preferable way when the application sends many GraphQL requests in parallel.

Fixed

• Debot module:
  • If DEngine received a non-zero exit_code while emulating a transaction while sending a message, DEngine will call onErrorId callback of the message.

[1.31.0] – 2022-03-09

New

crypto module:

• Cryptobox introduced: root crypto object that stores encrypted secret and acts as a factory for all crypto primitives used in SDK. Crypto box provides signing and encryption boxes.

  Functions: create_crypto_box - initializes cryptobox with secret remove_crypto_box - removes cryptobox and overwrites all secrets with zeroes get_crypto_box_seed_phrase

  • returns decrypted seed phrase get_crypto_box_info - returns encrypted cryptobox secret for next cryptobox initializations get_signing_box_from_crypto_box
  • derives signing box from secret get_encryption_box_from_crypto_box
  • derives encryption box from secret clear_crypto_box_secret_cache
  • forces secret cache (signing and encryption) clean up (overwrites all secrets with zeroes).

• Support of initCodeHash in tvm: X-Evernode-Expected-Account-Boc-Version=2 http header added to graphql requests. value=2 means that SDK requests the latest account boc version with initCodeHash support from API. This was done because new boc version is not compatible with old transaction executor, i.e. with previous SDK versions. New transaction executor is compatible with new and old boc formats. New SDK asks for new boc format if it exists,if it does not - old boc version is returned. Previous version of SDK will fetch only old version without initCodeHash support.

Attention! Migrate your applications to the new SDK version ASAP because in some period of time we will stop supporting old boc version in API and default value of X-Evernode-Expected-Account-Boc-Version on backend side will become 2, missing value will cause an error. Now default value on API side is Null which means that API returns the old version. This is done to avoid breaking changes in existing applications and give time to migrate to the new SDK.

Fixed

• Documentation generator for app object interface fills documentation from ParamsOfXXXAppObject enum.
• Documentation generator for function with obj parameter add this parameter into parameters section with link to appropriate AppObject interface.

[1.30.0] – 2022-02-04

New

• Added boc.encode_external_in_message function to encode message BOC based on a low level message parts such as a body, state init etc.
• Added net.subscribe function to start a low level GraphQL subscription.
• Added support for new MYCODE TVM command in tvm.run_tvm and tvm.run_get functions.

New

• Added abi.encode_boc function to encode parameters with values to BOC, using ABI types.
• Added support of address type in boc.encode_boc.
• All fetch requests are now called with timeouts to prevent freezing in case of infinite answer.
• Support of MYCODE instruction in TVM

[1.28.1] – 2022-01-25

Fixed

• Support breaking changes in ton-labs-block-json v0.7.1
• Updated endpoints for main.ton.dev alias.

[1.28.0] – 2021-12-24

New

• Debot module:
  • Аdded float numbers support for Json interface
• Added guide for custom giver usage.

Fixed

• Debot module: fixed a bug in Query.query function called with an empty variables field.

[1.27.1] – 2021-12-09

Fixed

• Empty function_name field in the "create run message failed" error.

[1.27.0] – 2021-12-06

New

Function abi.encode_initial_data which encodes initial account data with initial values for the contract's static variables and owner's public key. This function is analogue of tvm.buildDataInit function in Solidity.

Fixed

• Subscription for Counterparties failed with 'Unknown type "CounterpartieFilter"' error.

[1.26.1] – 2021-12-01

Fixed

• Fixed building and warning.

[1.26.0] – 2021-11-25

New

• Debot module:
  • Аdded allow_no_signature parameter to decode_and_fix_ext_msg() and onerror_id return value to prepare_ext_in_message() inner functions used in TS4.
  • Added support for async external calls.
  • Query interface extended with waitForCollection and query methods. waitForCollection allows to wait for completion of async external calls.
  • Added support for DeBots with ABI 2.2.

Function proofs.proof_message_data which proves message data, retrieved from Graphql API.

[1.25.0] – 2021-11-08

New

• New module proofs is introduced!

• Functions proofs.proof_block_data and proofs.proof_transaction_data which prove block data, retrieved from Graphql API.

  These are the first functions from proofs series :) Wait for others(proof_account_data , proof_message_data) in the next releases.

  Read about them more in the documentation.

• abi.decode_boc function to decode custom BOC data into JSON parameters.

• Ref(<ParamType>) type was added to ABI. Solidity functions use ABI types for builder encoding. The simplest way to decode such a BOC is to use ABI decoding. ABI has it own rules for fields layout in cells so manually encoded BOC can not be described in terms of ABI rules. To solve this problem we introduce a new ABI type Ref(<ParamType>) which allows to store ParamType ABI parameter in cell reference and, thus, decode manually encoded BOCs. This type is available only in decode_boc function and will not be available in ABI messages encoding until it is included into some ABI revision.

[1.24.0] – 2021-10-18

New

• boc.get_boc_depth function to get depth of the provided boc.

• boc.decode_tvc function returns additional fields code_hash, code_depth, data_hash , data_depth and compiler_version

• Debot module:

  • added parse function to Json interface.

[1.23.0] – 2021-10-05

New

• boc.get_code_salt and boc.set_code_salt functions for contract code salt management.
• boc.encode_tvc and boc.decode_tvc functions for TVC image encoding and decoding
• boc.get_compiler_version function extracting compiler version from contract code
• abi.update_initial_data and abi.decode_initial_data function for pre-deployment contract data management

[1.22.0] – 2021-09-20

New

• ABI v2.2 with fixed message body layout supported. See the specification .

  Now, for contracts with ABI version < 2.2 compact layout will still be used for compatibility, for contracts with ABI version 2.2 and more - fixed layout will be used. Please, make sure that you updated the ABI if you recompiled your contract with 2.2 ABI, or you may get an inconsistent contract behaviour.

• Debot module:

  • added getEncryptionBoxInfo, getSigningBoxInfo functions to Sdk interface.
  • implemented Query DeBot interface in DEngine.

[1.21.5] – 2021-09-13

Fixed

• abi.encode_message and processing.process_message created invalid deploy message in case of Signer::None was used, and contract could not be deployed.

New

• Support MacOS aarch64 target

[1.21.3] – 2021-09-02

New

• Information about used endpoint is added to subscription errors.
• Graphql response error codes 500-599 are treated as retriable network errors

[1.21.2] – 2021-08-25

Fixed

• Updated crypto libraries in order to fix building.

[1.21.1] – 2021-08-24

Fixed

• http errors were not processed as network errors and didn't lead to endpoint reconnect and request retry

[1.21.0] – 2021-08-18

New

• crypto.create_encryption_box function for creating SDK-defined encryption boxes. First supported algorithm - AES with CBC mode.
• Debot module:
  • Аdded public prepare_ext_in_message function.

Fixed

• tvm.run_executor did not work when SDK is configured to use TONOS SE, because of incomplete default blockchain configuration. Now mainnet config from key block 10660619 (last key block at the moment of fix) is used as default.

[1.20.1] – 2021-07-30

New

• Added support of contract error messages. Error messages (for example, require(...) in Solidity) are now parsed by SDK and returned in error message. New field contract_error was added to error's data.

Fixed

• Fixed problem with WASM binaries (everx-labs/ever-types#42)

[1.20.0] – 2021-07-16

New

• ABI version 2.1 supported. Attention! If you work with contracts, that contain String parameters, then during migration from ABI 2.0 to 2.1 you will need to remove all String type conversions to bytes and back and pass string to your contract as is.

• Now all requests to GraphQL are limited with timeout to react on unexpected server unavailability. Existing timeouts in waiting functions keep the same behaviour. All other requests timeout now can be set with net.query_timeout config parameter. Its default value is 60000 ms

• Debot module:

  • added encrypt, decrypt functions to Sdk interface which accept encryption box handles.

Fixed

• Deployment with empty signer in cases of public key set in TVC or deploy set.

[1.19.0] – 2021-07-07

New

• get_address_type function in utils module, which validates address and returns its type. See the documentation.
• decode_account_data function in abi module that converts account data BOC into JSON representation according to ABI 2.1. See the documentation.
• Diagnostic fields filter and timestamp added to wait_for_collection error
• main.ton.dev and net.ton.dev endpoints that will be deprecated on 12.07.21 are now replaced with proper endpoints list, if they were specified in network endpoints config

Fixed

• Search of the first master blocks during the network start period was fixed in blocks and transactions iterators

[1.18.0] – 2021-06-26

New

• Iterators in net module: robust way to iterate blockchain items (blocks, transactions) in specified range. See documentation for create_block_iterator , create_transaction_iterator, resume_block_iterator, resume_transaction_iterator, iterator_next, iterator_remove functions.
• Library adds http:// protocol to endpoints localhost, 127.0.0.1, 0.0.0.0 if protocol isn't specified in config.
• Debot module:
  • added tests for Json interface.

[1.17.0] – 2021-06-21

New

• Added support of external encryption boxes. See the documentation
• Debot module:
  • Dengine waits for completion of all transactions in a chain initiated by debot's onchain call.

[1.16.1] – 2021-06-16

New

• timeout option to query_transaction_tree – timeout used to limit waiting time for the next message and transaction in the transaction tree.

Improved

• Improved error messages regarding ABI and JSON interface. SDK now shows additional tips for the user in cases of errors.

Fixed

• Warnings in Rust 1.52+. Little fixes in the documentation.
• total_output field in fees was always 0.
• query_transaction_tree didn't wait for messages.

[1.16.0] – 2021-05-25

New

• query_transaction_tree function that returns messages and transactions tree produced by the specified message was added to net module. See the documentation

Fixed

• AbiData.key type changed to u32.
• attempt to use orderBy instead of order in query_collection will raise error.

[1.15.0] – 2021-05-18

New

• Sync latency detection increases connection reliability. Library will change the current endpoint when it detects data sync latency on it.

• Configuration parameters: latency_detection_interval, max_latency. See client documentation for details.

• Debot module:

  • signing messages with signing box handles returned from debots.
  • return any sdk errors to debot in case of external calls.
  • defining signing box handle used to sign message in approve callback.

[1.14.1] – 2021-04-29

Fixed

• Fixed building under Rust versions older than 1.51.

[1.14.0] – 2021-04-28

New

• Debot module:
  • implementation of Network DeBot interface in DEngine.
  • implementation of signHash function in Sdk interface.

Fixed

• Debot module:
  • fixed bug in Json interface with supporting nested structures and arrays of structures.
  • fixed bug in Json interface with keys containing hyphens.

[1.13.0] – 2021-04-23

New

• net.query_counterparties - allows to query and paginate through the list of accounts that the specified account has interacted with, sorted by the time of the last internal message between accounts. Subscription to counterparties collection is available via net.subscribe_collection function.

• Blockchain interaction reliability improvement (broadcast): library sends external inbound messages simultaneously to the N randomly chosen endpoints. If all N endpoints failed to responce then library repeats sending to another random N endpoints (except the failed one). If all the available endpoints fail to respond then library throws error. The N parameter is taken from config.network.sending_endpoint_count (default is 2).

• Blockchain interaction reliability improvement (bad delivery list): library tracks endpoints with bad message delivery (expired messages). These endpoints have lower priority when library chooses endpoints to send message.

• Debot module:

  • Implementation of Json DeBot interface in DEngine.

Fixed

• BuilderOp::Integer.size type has changed from u8 to u32.
• Debot Module:
  • Sdk interface function getAccountsDataByHash didn't find accounts by code_hash with leading zero.

[1.12.0] – 2021-04-01

New

• utils.compress_zstd compresses data using Facebook's Zstandard algorithm.
• utils.decompress_zstd decompresses data using Facebook's Zstandard algorithm.
• Debot module:
  • init function that creates an instance of DeBot and returns DeBot metadata.
  • Dengine fetches metadata form DeBot by calling 2 mandatory functions: getRequiredInterfaces and getDebotInfo. This data is returned by fetch and init functions.
  • approve DeBot Browser callback which is called by DEngine to request permission for DeBot activities.

Changed

• Debot Module:
  • [breaking] fetch function does't create an instance of debot. It returns DeBot metadata (DebotInfo).
  • [breaking] start function does't create an instance of debot. It accepts DeBot handle created in init function.

[1.11.2] – 2021-03-19

Refactor

• Some internal refactor due to ton-block changes

[1.11.1] – 2021-03-15

New

• Giver address in tests is calculated from secret key. Default values are provided for TON OS SE giver

[1.11.0] – 2021-03-05

New

• utils.calc_storage_fee function to calculate account storage fee over a some time period.
• Debot Module:
  • Added unstable functions to Sdk interface: getAccountsDataByHash

[1.10.0] – 2021-03-04

New

• Add optional field src_address to ParamsOfEncodeInternalMessage.
• Field abi in ParamsOfEncodeInternalMessage is optional and can be None if call_set and deploy_set are None.
• boc.encode_boc function provides ability to build and serialize any custom tree of cells. Application can use several base Builder serialization primitives like integers, bitstrings and nested cells.
• boc.get_blockchain_config function can extract blockchain configuration from key block and also from zerostate.
• tvm module functions download current blockchain configuration if net is initialized with DApp Server endpoints. Otherwise default configuration is used.
• Debot Module:
  • Support for debot invoking in Debot Engine. send browser callback is used not only for interface calls but to invoke debots.
  • start and fetch functions returns debot ABI.
  • Added new built-in interface Hex which implements hexadecimal encoding and decoding.
  • Added unstable functions to Sdk interface: naclBox, naclBoxOpen, naclKeypairFromSecret, getAccountCodeHash.

Changed

• Both call_set and deploy_set in ParamsOfEncodeInternalMessage can be omitted. In this case encode_internal_message generates internal message with empty body.
• Debot Module:
  • send function accepts one argument - serialized internal message as string encoded into base64.

Documentation

• Debot browser app object and signing box app object descriptions added
• functions-helpers for enum type variable creation for Signer , Abi, ParamsOfAppDebotBrowser

Fixed

• doc generator: app object interface description, constructor functions-helpers for enum type variable creation, added new line in the end if api.json
• library libsecp256k1 upgraded to fix https://rustsec.org/advisories/RUSTSEC-2019-0027

1.9.0 Feb 19, 2021

New

• tuple_list_as_array parameter in tvm.run_get function which controls lists representation. Default is stack-like based on nested tuples. If set to true then returned lists are encoded as plain arrays. Use this option if you receive this error on Web: "Runtime error. Unreachable code should not be executed..." This reduces stack size requirements for long lists.
• function_name field of CallSet structure can be the name or id (as string in hex starting with 0x) of the called function.
• Fields config_servers, query_url, account_address, gas_used added into specific errors' ClientError.data object.

Fixed

• Binaries download links are now under https protocol
• If you receive this error on Web: "Runtime error. Unreachable code should not be executed..." in run_get, use the new parameter tuple_list_as_array = true . See the documentation. This may happen, for example, when elector contract contains too many participants

1.8.0 Feb 11, 2021

New

• Debot Module:
  • Added new built-in interface Msg which allows to send external message to blockchain and sign it with supplied keypair.

Fixed

• crypto.hdkey_public_from_xprv used compressed 33-byte form instead of normal 32-byte.

1.7.0 Feb 9, 2021

New

• BOC cache management functions were introduced:
  • boc.cache_set,
  • boc.cache_get
  • boc.cache_unpin
• Now functions that take boc as a parameter can also take a reference to boc cash instead so that it deсreases the number of boc serialization and deserializations which drastically improves performance of run_tvm and run_executor expecially in case of numerous calls on the same data.
• boc_cache parameter in tvm.run_tvm and tvm.run_executor functions to save resulting messages and account BOCs into cache.
• return_updated_account flag parameter introduced in tvm.run_tvm and tvm.run_executor functions to return updated account state. Important: by default this flag is false and account data is not returned.
• abi.encode_internal_message function to encode an internal ABI-compatible message.
• Debot Module:
  • Support for get-methods and external calls in debots. Debots can send external inbound messages to destination contracts (signed - for external calls and unsigned - for get-methods) using native language syntax without actions.
  • Built-in debot interfaces (interfaces implemented by DEngine). Added two built-in interfaces: base64 and Sdk.
  • Added DebotInterfaceExecutor to automatically route messages to destination interfaces.
  • Debot's fetch function is optional now. New debots can implement only start function.

1.6.3 Feb 4, 2021

Fixed

• Expired message wasn't retried if local execution succeeded.

1.6.2 Feb 3, 2021

Added

• ResponseHandler type description into modules.md.

Fixed

• net.batch_query parameters serialization did't match to docs.
• Module description in docs generator contains null instead of summary.
• Function result section header hadn't the line separator before.

1.6.0 Jan 29, 2021

New

• nacl_sign_detached_verify function to verify detached signature.
• aggregate_collection function as a wrapper for GraphQL aggregation queries.
• batch_query function performs multiple queries per single fetch.
• Active endpoint invalidation in case of network error occurring.
• network.network_retries_count config parameter is deprecated. network.max_reconnect_timeout is introduced that allows to specify maximum network resolving timeout. Default value is 2 min.
• initial_pubkey field in DeploySet to specify public key instead of one from TVC file or provided by signer.
• Support for debot interfaces:
  • send Browser Callback to send messages with interface calls to Browser.
  • new variant ParamsOfAppDebotBrowser::Send.
  • send API function to send messages from Browser to Debot.
  • run_output.rs - internal structure RunOutput to filter messages generated by debot to 4 categories: interface calls, external calls, get-method calls and invoke calls.

Fixed

• Device time synchronization is checked only in send_message. Data querying does not require proper time now

1.5.2 Dec 30, 2020

Fixed

• net module functions waits for net.resume call instead of returning error if called while the module is suspended

Documentation

• How to work with Application Objects specification added

1.5.1 Dec 28, 2020

Fixed

• Updated the dependence on ton-labs-abi

1.5.0 Dec 25, 2020

New

• reconnect_timeout parameter in NetworkConfig.
• endpoints parameter in NetworkConfig. It contains the list of available server addresses to connect. SDK will use one them with the least connect time. server_address parameter is still supported but endpoints is prevailing.
• net.fetch_endpoints function to receive available endpoints from server.
• net.set_endpoints function to set endpoints list for using on next reconnect.
• ErrorCode type in each module spec in api.json.

Fixed

• send GQL_TERMINATE_CONNECTION and close websocket on leaving ws loop.

1.4.0 Dec 18, 2020

New

• GraphQL optimization: use single web socket to serve all subscriptions.
• Support for the keep-alive messages from the GraphQL server.
• tonclient-core-version http header.
• net.find_last_shard_block function returning account shard last block ID.
• boc.get_code_from_tvc function extracting contract code from TVC image.
• Debot Module:
  • Add new variant ParamsOfAppDebotBrowser::SwitchCompleted to notify browser when all context actions are shown.
  • Added new 3 engine routines for crypto operations and 1 routine for querying account state ( balance, state type, code, data) that can be used in debots.

Fixed

• Debot Module:
  • Invoked debot terminated correctly after error occurred during execution of one of its actions. Initial prev_state of invoked debot changed to STATE_EXIT.
  • Fixed double jumping to current context in invoker debot after returning control to it from invoked debot.
  • Fixed conversation of exception codes thrown by debots to their user-friendly description.

1.3.0 Dec 8, 2020

Featured

• net.query method . Performs custom graphql query that can be copied directly from the playground.
• net.suspend and net.resume methods for disabling and enabling network activity. One of the possible use-cases is to manage subscriptions when a mobile application is brought to the background and into the foreground again.
• Smart summary and description doc separation.
• ts-generator includes doc comments in JSDoc format.

1.2.0 Nov 26, 2020

Featured

• UNSTABLE API. This API is experimental. It can be changed in the next releases. debot module was added with debot engine functions, such as : start, fetch, execute , remove. See the debot module documentation for more info. Check our tests for code examples.

• External signing was supported for message encoding: SigningBox type for Signer enum was supported. Now it is possible to sign messages with externally implemented signing box interface without private key disclosure to the library. Can be used in case of signing via HSM API or via cold wallet - when there is no access to the private key.

  It is also possible to create a Signing Box instance inside SDK - from a key pair passed into the library with get_signing_box method. It can be used for some test cases. Also it increases security - you need to pass your keys one time only.

  Check the crypto module documentation for SigningBoxHandle type and register_signing_box , get_signing_box, signing_box_get_public_key, signing_box_sign. Check our tests for code examples.

Fixed

• panic after tc_destroy_context call. Now all contexts use global async runtime
• field mnemonic_hdkey_compliant was removed from CryptoConfig (unused by the library)

• run_executor, run_tvm now return exit_arg in case of TVM errors.
• Create the build_info.json on the build stage.
• Abi::Contract variant as an alias to deprecated Abi::Serialized
• Abi::Json variant to specify an ABI as a raw JSON string.
• api.json now contains details about numeric types: Number and BigInt are now have new fields number_type and number_size.

Fixed

• TS generator fix some field names that is an invalid JS identifiers.
• Use install_name_tool to fix loading library paths at libton_client.dylib.
• api.json is reduced, so it can't contains tuple types, only structs. All types are exactly match to JSON.
• out_of_sync_threshold config parameter is u32

Unstable

• tc_request_ptr function to use pointers void* instead of request_id u32. This feature is UNSTABLE yet.

1.0.0 Oct 27, 2020

Differences between Core SDK v0 and v1

• All api functions are defined in mod.rs of appropriate modules
• Function names are the same as API function names: module.function_name
• Parameters naming:
  • In snake case
  • Base64 suffix is removed from parameter names. For example, bocBase64 is changed to boc
• Parsed boc replaced with unparsed boc in all function input parameters
• All functions take byte arrays in a defined encoding:
  • base64 - encoding used for byte arrays of variable length: text, images, etc.
  • hex-lower-case - encoding used to encode fixed length bit sequences: hashes, keys, salt, etc.
• contracts module is splitted into 5 modules:
  • tvm - embedded TVM execution functions
  • boc - raw cell and BOC manipulation functions
  • abi - abi-compatible messages creation and parsing functions
  • processing - blockchain interaction functions
  • utils - has only convert_address ATM, later will be used for some useful stuff
• query module is renamed to net
• new client module with functions version, api_reference
• All the environment functions (fetch, websocket, spawn, now, etc.) were abstracted behind a separate environment layer crate ClientEnv. The standard core env layer implementation is in std_client_env . Later (in 1.1 release) web_client_env implementation for Web will be added.
• Error codes are distributed across the modules the following way: client - 0..99, crypto - 100..199, boc - 200..299, abi - 300..399, tvm - 400..499, processing - 500..599, net - 600..699
• Error descriptions related to a module are described in error.rs file in the module's folder
• decode_message, process_message, wait_for_transaction, run_tvm, run_executor, etc. (all the functions that return decoded messages) now returns int*/uint* data as a string which can be either decimal or 0x-prefixed hex string. Hex representation can be in any register and have any number of leading zeroes.

Featured

• All the functions are asynchronous

• All the functions that can be called via JSON-api are public, so that they can be used directly without JSON-api.

• Inline documentation and api reference added.

• [breaking] interops.rs, tonclient.h. create_context now takes config parameter - context creation and setup happen at the same time. Config structure has been changed.

• [breaking] crypto module. default values for mnemonic-related functions have been changed:

  dictionary is 1, for word count is 12, derivation path is 'm/44'/396'/0'/0/0

• [breaking] crypto module. removed word_count parameter from words function

• [breaking] crypto module. compliant parameter is removed from functions mnemonic_derive_sign_keys, hdkey_xprv_derive_path, hdkey_xprv_derive,

• [new] boc module. Functions parse_block, parse_account, parse_message , parse_transaction that parse bocs to JSONs are introduced.

• [breaking] net module. Functions query , wait.for, subscribe are renamed to query_collection, wait_for_collection, subscribe_collection

  table parameter is renamed to collection. filter parameter is now optional and of json type (passed as json object instead of string)

• [breaking] net module. Function get.next is removed.

• [breaking] net module.subscribe_collection now uses callback to return data.

• [breaking] abi module. decode_message introduced instead of decode_unknown_run , decode_run_output

• [breaking] abi module. encode_message introduced instead of encode_unsigned_deploy_message , encode_unsigned_run_message, run.encode_message, deploy.encode_message

• [breaking] abi module. signer: Signer parameter used instead of key_pair: KeyPair , which can be of None (unsigned message will be produced), External (data to be signed +unsigned message), Keys (signed message will be produced), SigningBox (message will be signed using a provided interface - will be supported in coming releases)

• [breaking] processing module. process_message introduced instead of deploy and run. Parameter set was drastically changed.

• [breaking] processing module. process_message - now, if the contract was already deployed, deploy fails with an exception of double constructor call.

• [new] processing module. process_message - any function can be called at deploy, not only constructor, also there can be no function call.

• [new] processing module. process_message now can optionally use callback to monitor message processing (creation, sending, shard block fetching, transaction receiving).

• [fixed] processing module. process_message - deploy can be performed without a key pair

• [breaking] tvm module. run_local is divided into 2 functions run_tvm and run_executor.

• [new] tvm module. run_tvm function - performs contract code execution on tvm (part of compute phase). Helps to run contract methods without ACCEPT. Returns account state with updated data, list of external messages and (optional, for ABI contracts only) list of messages decoded data.

• [new] tvm module. run_executor function - performs full contract code execution on Transaction Executor (part of collator protocol that performs all phases and checks and - as a successful result - forms a transaction) Returns updated account state, parsed transaction, list of parsed messages with optional decoded message bodies.

• [breaking] tvm module. run_get does not download account boc from the network anymore, but takes account boc as a parameter.
