hevm/0.45.0

hevm [0.45.0]

Added

• Two new cheatcodes were added: sign(uint sk, bytes message) and addr(uint sk). Taken together
  these should allow for much more ergonomic testing of code that handles signed messages.
• Symbolic execution can deal with partially symbolic bytecode, allowing for symbolic constructor arguments to be given in tests.

Fixed

• Fixed a bug in the abiencoding.
• Fixed the range being generated by ints.
• hevm flatten combines the SPDX license identifiers of all source files.

Changed

• updated nixpkgs to the 20.09 channel
• Arbitrary instance of AbiType can no longer generate a tuple

dapp [0.32.2]

Changed

• updated nixpkgs to the 20.09 channel

seth [0.10.1]

Added

• Thanks to an upgrade in ethsign, seth is more likely to find your ledger live
  account without having to set ETH_HDPATH.

Changed

• updated nixpkgs to the 20.09 channel

Fixed

• seth calldata returns correct abiencoding

hevm/0.44.1

Changed

• hevm cheatcodes now accept symbolic arguments, allowing e.g. symbolic jumps in time in unit tests
• More efficient arithmetic overflow checks by translating queries to a more intelligent form.

dapp/0.32.1

dapp 0.32.1

Fixed

• dapp init works with the new standard-json architecture
• dapp verify-contract works with the new standard-json architecture

hevm 0.44.1

Changed

• hevm cheatcodes now accept symbolic arguments, allowing e.g. symbolic jumps in time in unit tests
• More efficient arithmetic overflow checks by translating queries to a more intelligent form.

hevm/0.44.0

hevm

0.44.0 - 2020-01-26

Added

• hevm now accepts solidity json output built via --standard-json as
  well as --combined-json.
• addresses in the trace output are prefixed with ContractName@0x...
  if there is a corresponding contract and @0x... otherwise.

Fixed

• If the --address flag is present in hevm exec or hevm symbolic,
  it overrides the contract address at which a contract will be created.
• Address pretty printing
• Updated sbv to 8.9.5 to fix "non-const in array declaration" cvc4 issue with ds-test.

dapp

[0.32.0] - 2021-01-26

Changed

• dapp build, dapp test, dapp --make-library-state, dapp create now use solidity output
  generated via --standard-json instead of --combined-json. Building via the old format is
  still possible via dapp build --legacy, but is considered deprecated and will be removed in
  future releases.

The standard json used by dapp build can be set using the environment variable:
DAPP_STANDARD_JSON, and defaults to the result of dapp mk-standard-json.

• dapp --find-libraries no longer requires --extract: libraries do not need to be
  built to be found.

Added

• dapp mk-standard-json command to generate a standard json for setting Solidity compiler options.
  The settings can be tweaked using the following environment variables:
  • DAPP_REMAPPINGS (defaults to the result of dapp remappings)
  • DAPP_LIBRARIES (defaults to the result of dapp --find-libraries)
  • DAPP_BUILD_OPTIMIZE (defaults to false)

Removed

• SOLC_FLAGS. To modify the compiler settings, use a custom standard json and set
  the filename as argument to DAPP_STANDARD_JSON.

Fixed

• dapp create <contract> --verify now passes the qualified path to dapp verify-contract,
  as expected.

seth

[0.10.0] - 2021-01-26

Changed

• seth combined-json was renamed to seth-solc and invokes solc
  using the --standard-json input.
• seth bundle-source correctly interprets etherscan sources using
  standard json
• the --gas-price argument can optionally accept a gwei suffix
  i.e. seth call --gas-price 100gwei ...

hevm/0.43.2

0.43.2 - 2020-12-10

Changed

• The default smttimeout has been increased from 20s to 30s

seth/0.9.4

[0.9.4] - 2020-12-10

Added

• seth --use can find solc versions in the nix store even if they are not present on PATH

Fixed

• Correct help text for seth --use

hevm/0.43.1

0.43.1 - 2020-12-10

Changed

• Counterexamples from symbolic tests now show clearer failure reasons

Fixed

• Symbolic tests now work with RPC
• Branch selection is working again in the interactive debugger

dapp/0.31.1

[0.31.1] - 2020-12-10

Added

• dapp --use can find solc versions in the nix store even if they are not present on PATH

Fixed

• Corrected help text for solc version installation

seth/0.9.3

[0.9.3] - 2020-11-29

• seth --use searches directly for binaries in your path, rather than
  using nix run, giving a significant speed boost.

hevm/0.43.0

0.43.0 - 2020-11-29

Added

• A --show-tree option to hevm symbolic which prints the execution tree explored.
• Some symbolic terms are displayed with richer semantic information, instead of the black box <symbolic>.
• hevm dapp-test now supports symbolic execution of test methods that are prefixed with prove or proveFail
• The hevm interactive alias has been removed, as it is equivalent to hevm dapp-test --debug
• hevm dapp-test --match now matches on contract name and file path, as well as test name
• Step through the callstack in debug mode using the arrow keys

Changed

• dapp-test trace output now detects ds-note events and shows LogNote
• create addresses are shown with @<address> in the trace
• DSTest.setUp() is only run if it exists, rather than failing
• support new ds-test log_named_x(string, x) (previously bytes32 keys)
• return arguments are fully displayed in the trace (previously only a single word)
• return/revert trace will now show the correct source position
