repo

  • Using new model for eosio.cdt cmake subsystem for building libraries.
  • Added new libraries for native support for native compilation for testing and "scratch pad" compilation for contract developers.

eosiolib

  • Added new set of functions (eosio::check) to supersede eosio_assert functions #318
    • overloads to support eosio_assert, eosio_assert_message and eosio_assert_code are supported.
    • these new functions should increase performance of smart contracts by not calling the intrinsic unless the test condition fails.
  • Removed memory.h #318
  • Removed activate_feature intrinsic from privileged.h #318
  • Resolved issues with eosio::print and std::string #318
  • Replaced all occurrences of eosio_assert with eosio::check #318
  • Allow for ""_n to be used to create a zero name (eosio::name{0}) #311
  • Added c++ guards on system.h #312

nativelib

  • Added a minimal crt for native contract compilation #317
  • Build libc, libcxx, and eosiolib for native linkage #317
  • Added framework for setting and getting intrinsics core functions. #317
    • In the future libraries can be built to fill in a default implementation of the complex intrinsics. Currently only the eosio_assert*, memcpy/cmp/move, soft float, and print* intrinsics have usable defaults, all others will assert with the message "unsupported intrinsic". Also, only the print* intrinsics can be reset in terms of their default functionality.
  • A testing framework for supporting eosio_assert/eosio::check as catchable and the ability to assert in the test or contract code and continue the test forward. #317
    • REQUIRE_ASSERT and CHECK_ASSERT function much like BOOST's CHECK_THROW and REQUIRE_THROW, but use the assert message as the predicate instead of an exception type. This checking the assertion message can either be a simple string, which will do a 1 to 1 match of this and the assert message, or you can pass it a lambda that takes a std::string and return a bool so more complex checking can be done.
    • CHECK_EQUAL and REQUIRE_EQUAL work almost identically to BOOST's.
    • For examples of how to use these see ./tests/unit/system_tests.cpp or ./tests/unit/name_tests.cpp.
  • Test registration to support CTest and pretty print which tests pass or fail. #317

cmake

  • A new pattern for cmake use in smart contract development. #291
    • This new pattern utilizes the EosioWasmToolchain.cmake as a cmake toolchain file and uses an external cmake project to build the contract code, see the new eosio-init tool.
  • To support native builds with eosio-cpp two new macros add_native_executable and add_native_library, these work identically to cmake's add_executable and add_library.

tools

  • New tool eosio-init is introduced #317
    • This tool will generate a project for smart contract development, either as a bare eosio-cpp project or cmake project. This tool takes a required project name, an optional path and an optional bare flag.
      • The "bare" version will generate a <project name>.hpp, a <project name>.cpp, a <project name>.contracts.md and a readme with how to build the contract.
      • The default/non-bare version will create a source tree with the proper cmake files, the above mentioned files in their respective folders, and a readme with instructions of how to build the contract.
  • Support for native builds with eosio-cpp/cc and eosio-ld #317
    • this is functionality is exposed with the fnative flag for each of the above tools.
  • Fixes for eosio-abidiff #298
  • Fixes for eosio-abigen for yet more nested types #291

eosiolib

  • symbol.hpp

eosiolib C API

  • addition of uint64_t typedef capi_name #132
  • removal of uint64_t typedefs #132
    • account_name
    • permission_name
    • scope_name
    • table_name
    • action_name
      • these have been replaced by capi_name, and as a practice should not be used. The new version of the name type should be used to replace these instances. This decision was made because of bad implict casting issues with uint64_t and the new pattern should allow for better type safety.
    • symbol_name
      • this has no C equivalent and is superceded by the symbol_code struct. As with the previously mentioned named types, this was removed and replaced with symbol_code to allow for better type safety in contracts. To use a symbol, i.e. symbol name and precision, use the symbol class.
  • removal of time and weight_type typedefs #132
  • removal of the typedefs transaction_id_type and block_id_type #132

eosiolib/asset.hpp

eosiolib/contract.hpp

  • The constructor for eosio::contract now takes an eosio::name for the receiver, an eosio::name for the code, and a eosio::datastream<const char*> for the datastream used for the contract. The last argument is for manually unpacking an action, see the section on eosio::ignore for a more indepth usage. #136

  • removed the macro ACTION #136

  • the account and permission arguments of eosio::check_transaction_authorization are both eosio::name now instead of uint64_t #132

eosiolib/ignore.hpp

  • added new type ignore #133

libcxx

  • removed sstream, with the intent to return this after more has been done. #142
  • added __cxa_pure_virtual to allow for pure virtual methods in contract classes. #142
  • std::to_string now works without the issues of stack overflows. #142

attributes
