      Use BLAKE2b 256-bit hashes for selectors (#680) · e22a0feb
      Hero Bird authored
      * use BLAKE2b 256-bit hashes for selectors
      
      Before this PR we accidentally used BLAKE2b 512-bit hashing.
      Using 256-bit versions is important for smart contracts so that smart contracts can compute selector hashes on their own through the built-in contracts-pallet hash support which includes BLAKE2b 256-bit but not 512-bit.

      Implement ink! chain extensions (#592) · 59a7f5ed
      Hero Bird authored
      
      
      * add new tests for #[ink(namespace = ..)] and #[ink(selector = ..)] attrs
      
      * [lang] implement new errors for ink! attributes: namespace, selector
      
      * add #[ink(extension = N: u32)] attribute
      
      * apply rustfmt
      
      * [lang] add initial implementation of chain extension proc. macro
      
      * [lang] rename AttributeArg -> AttributeFrag
      
      * rename AttributeFrag::kind field to arg
      
      * rename AttributeArgKind -> AttributeArg
      
      Also introduce a new AttributeArgKind type and AttributeArg::kind method.
      
      * [lang] apply rustfmt
      
      * add Display impl for AttributeArgKind
      
      * [lang] use AttributeArgKind in sanitize_attributes and ensure_first methods
      
      * [lang/ir] improve error reporting for duplicate ink! attributes
      
      * [lang/ir] refactoring and improvements to chain extension IR impl
      
      * [lang/ir] add tests for IR implementation of chain extensions
      
      * [lang/ir] remove some code dupe
      
      * [lang/ir] add getters to ChainExtension
      
      * [lang/ir] add re-exports for ChainExtension definitions
      
      * [lang/codegen] add initial impl for ChainExtensions
      
      * [env] add ChainExtension assoc type to the Environment trait
      
      * [lang] initial impl to make it possible to use chain extension syntax
      
      * [env] improvements to chain extensions API
      
      Also removes the unstable crate feature guarding the feature.
      
      * [lang/macro] add UI test for chain extension
      
      * [lang/macro] register new UI test
      
      * [lang/codegen] fix some codegen bugs with new chain extension feature
      
      * [lang, env] apply rustfmt
      
      * [lang/ir] apply clippy suggestions and fix outdated error messages
      
      * [lang/ir] fix some tests and incorrect error messages
      
      * [examples] apply clippy suggestion
      
      * add ErrorCode to ink! chain extension trait
      
      * add FromStatusCode trait to ink_lang
      
      * add #[ink(expect_output)] and #[ink(expect_ok)] attributes
      
      Also add their handling for the #[ink::chain_extension] proc. macro.
      
      * add ink_lang::IsResultType trait
      
      * add ChainExtensionMethodInputs iterator
      
      * hide docs for IsResultType trait
      
      * add some docs to chain extension codegen
      
      * implement expect_ok and expect_output where bounds in codegen
      
      * apply code review suggestions by (cmichi)
      
      * add ReturnCode::into_u32 getter
      
      * change return type of ext::call_chain_extension: RetCode -> u32
      
      Chain extensions do not follow the general scheme of error return code because they have their own set of errors that is custom defined by the author of the chain extension.
      
      * [lang] add ChainExtension trait
      
      Not yet sure we need it.
      
      * change EnvBackend::call_chain_extension signature
      
      The new signature is much more low-level and supports all the different ways to call a chain extension method.
      This commit already implements the chain extension call on the on-chain environment.
      More work needs to be done to properly support this for the off-chain environment.
      
      * remove old high-level API for calling chain extension methods
      
      * [env] add new high-level module to handle chain extension calls
      
      * rename ChainExtensionMethodInstance -> ChainExtensionMethod
      
      * [env] add doc examples to chain extension method API
      
      * apply rustfmt
      
      * [env] clippy: allow complex type in ChainExtensionMethod type state
      
      * silence some warnings
      
      * re-export IsResultType from ink_lang crate
      
      * [lang] remove FromStatusCode trait
      
      This trait already exists in the ink_env crate.
      
      * [lang] update codegen for chain extensions
      
      Not yet done but close.
      
      * [lang] update simple chain extension test
      
      Compiles now again.
      
      * apply rustfmt
      
      * update some license headers
      
      * [env] fix where bound
      
      * extend chain extension test case to cover all cases
      
      * add messages for read_small, access and unlock_access
      
      * fix some bugs with chain extension method signatures in test
      
      * fix some bugs and docs in chain extension test
      
      * fix test
      
      * update quickcheck to 1.0
      
      * [env] implement chain extension calling for off-chain env
      
      The new interface is much more lower-level and it is still impossible to use chain state from within the chain extension call. The latter must be fixed as soon as the off-chain environment receives its rework.
      
      * apply rustfmt
      
      * add docs to #[ink::chain_extension] proc. macro
      
      * rename env_types -> env everywhere
      
      * make doc examples for #[ink::chain_extension] compile
      
      * add yet another technical limitation
      
      * make link to simple.rs test case more stable (point to revision)
      
      * fix docs (code suggestion)

      Implement event topic code generation (#510) · 6f701e50
      Hero Bird authored
      * [env] remove unnecessary copy of no longer used mod.rs
      
      * [env, lang] make crates compile again under newest Rust nightly
      
      * [env] on-chain: enhance ScopedBuffer
      
      Add append_encoded and take_appended methods.
      
      * [env] remove old Topics trait
      
      * [env] add new Topics infrastructure
      
      * [env] implement new Topics infrastructure for on/off chain environments
      
      * [env] remove dummy event
      
      * [env] make env::topics::state mod externally accessible
      
      It stays hidden in docs.

      * [env] remove commented-out line
      
      * [lang/codegen] include event signature into topics
      
      This is the same as it is done for non-anonymous Solidity events.
      The signature of an ink! event is: ContractName::EventName.
      E.g. for ERC-20's Transfer event it is: Erc20::Transfer
      
      * [examples] ERC-20: adjust test for changes with event topics
