v0.4.2

Changes:

  • Add payable to all functions that want to receive Element (including the constructor and the fallback function).
  • Change _ to _; in modifiers.
  • Functions that want to receive Element have to specify the new payable modifier (otherwise they throw).
  • Contracts that want to receive Element with a plain "send" have to implement a fallback function with the payable modifier. Contracts now throw if no payable fallback function is defined and no function matches the signature.
  • Failing contract creation through "new" throws.
  • Division / modulus by zero throws.
  • Function call throws if target contract does not have code
  • Modifiers are required to contain _ (use if (false) _ as a workaround if needed).
  • Modifiers: return does not skip part in modifier after _ .
  • Placeholder statement _ in modifier now requires explicit ; .
  • ecrecover now returns zero if the input is malformed (it previously returned garbage).
  • The constant keyword cannot be used for constructors or the fallback function.
  • Removed --interface (Solidity interface) output option
  • JSON AST: General cleanup, renamed many nodes to match their C++ names.
  • JSON output: srcmap-runtime renamed to srcmapRuntime .
  • Moved (and reworked) standard library contracts from inside the compiler to github.com/elementrem/solidity/std ( import "std"; or import owned; do not work anymore).
  • Confusing and undocumented keyword after was removed.
  • New reserved words: abstract , hex , interface , payable , pure , static , view .

Features:

  • Hexadecimal string literals: hex"ab1248fe"
  • Internal: Inline assembly usable by the code generator.
  • Commandline interface: Using - as filename allows reading from stdin.
  • Interface JSON: Fallback function is now part of the ABI.
  • Interface: Version string now semver compatible.
  • Code generator: Do not provide "new account gas" if we know the called account exists.

Bugfixes:

  • JSON AST: Nodes were added at wrong parent
  • Why3 translator: Crash fix for exponentiation
  • Commandline Interface: linking libraries with underscores in their name.
  • Type Checker: Fallback function cannot return data anymore.
  • Code Generator: Fix crash when sha3() was used on unsupported types.
  • Code Generator: Manually set gas stipend for .send(0) .
  • Code Generator: Fix library functions being called from payable functions.
  • Type Checker: Fixed a crash about invalid array types.

You should make sure whether the solidity compiler is applied or not.

If the solidity is not applied, You can apply it manually.

"solc, the solidity compiler commandline interface\nVersion: 0.4.2 develop.2016.10.2+commit.3ba4422c.Linux.g++\n\npath: ./solc"
