* Create new branch * Define Address type (#763) * Define Address type * Define legal Address types for messages, parameters and fields. * Syntax for address types (#767) * Added address type to syntax, and fixed ambiguous grammar * Add location info to Address field identifiers * Type inference rules for addresses (#778) * assert_type_assignable * Use assert_type_assignable in TypeUtil. * Type inference rules for address types * Fix type_assignable and tests of same, introduce legal_procedure_parameter_type, and fix parser bug * Fix parser bug and typechecker issue * Refactor type equivalence tests * Assignable tests * Duplicate field check for address types * Remove fixed TODO * Move duplicate field check to Recursion.ml * Remove blank line * Reintroduce is_ground_type * Cosmetic change to pp_typ in case the address contains no fields * Addresses from JSONs should be read as ByStr20s * Reorder arguments to for_all2_exn in builtin argument traversal * Do not use type_assignable when comparing types derived from literal values * Use type_equiv in Schnorr calculations, and rename json_to_lit to json_to_lit_exn * Remote state read read syntax (#783) * Remote state read syntax and typechecking * _balance field must be accessible even when not declared * Change <- to <-- for remote reads * Add address type to map key and value types * Removed incorrect comment * Simple example contract for remote state reads, plus minor parser fix (#785) * Field initialiser bugs fixed (#787) * Fixed two bugs re. initialisers for address fields. * Update src/base/TypeChecker.ml Co-Authored-By: Vaivaswatha N <vaivaswatha@users.noreply.github.com> Co-authored-by: Vaivaswatha N <vaivaswatha@users.noreply.github.com> * Contract info should specify the defining lib for ADTs (#786) * Provide an external_fetch function in StateService (#805) * Add IPC methods to fetch external contract state * Provide means to specify external states via input JSONs * Add a dummy fetch_ext_state_value to StateIPCTestServer * Provide external_fetch service in StateService.ml * Fix compare function for identifiers and names. (#926) * Fix outstanding merge issues (#925) * Fix outstanding merge issues * fmt * Use assert_type_assignable rather than assert_type_equiv * fmt * `_sender` and `_this_address` are addresses (#801) * _sender is an address, eq should compare addresses as ByStr20 * Added addresses as legal ADT constructor arguments * Addresses in event fields output as ByStr20 * fmt * Missing merge file * Remote state reads practicalities (#927) * Name parameters to type_assignable and assert_type_assignable * address_typ to construct address type nodes * fmt * Allow parenthesised address types (#937) * Fetch external value IPC query cannot provide expected type as that isn't exactly known. * Allow fetching type only for remote fields * fmt * Remote state reads bugfixes (#945) * Use declared type rather than actual type in field env * Allow _this_address to be declared in address types * Disallow spids other than _this_address in address types * Remote state reads testserver (#948) * JSON parsing of external states * Add testsuite support for external states * Added remote state reads test contract * Test contract * implement remote map read * Add comment clarifying computing accessed value type * Fix issue with address types being lost * fmt Co-authored-by: Vaivaswatha Nagaraj <vaivaswatha@zilliqa.com> * Merge * Push immutable parameters via state service, along with fields * Push contract parameters to state service during migration * Revert "Push contract parameters to state service during migration" This reverts commit 2ea064c. * Revert "Push immutable parameters via state service, along with fields" This reverts commit 2cf3978. * Remote state reads dynamic typecheck (#953) * Parameter typechecker for addresses * Ignore types in init.json (not backward compatible), remove faulty assignability check for field initialisers * Dynamic typecheck of contract parameters * Missing commit of TypeUtil.mli * Dynamic typecheck of contract parameters * Minor tidying up * Comments added * Separate prepare_message from handle_message to allow for dynamic typechecks * Dynamic typecheck of transition parameters, plus some (not all) tests * Negative tests for addresses and ADTs * Remote state reads misc bugfixes (#954) * Address types are legal map value types * Fix type_assignable * Added comment about contravariance in custom ADTs * Tests of _this_address in address types and remote reads * Tests that messages, events and excetions use ByStr20 and not Address types * Forgot to add the new tests to Testcontracts.ml * Added assignability tests * Decrease sender balance on acceptance (#955) * make fmt * Do not pretty-print Lists as JSON arrays. This confuses the (#956) state parser in the blockchain unit test which cannot know if its a map or not (yet). I ended up running `make fmt` which resulted in some other changes as well, but just whitespace changes. Co-authored-by: Jacob Johannsen <jajocnn@gmail.com> * Fix missing stuff in #956 (#957) * Fix missing stuff in #956 * Change _this_address of test contract * Update owner address and balance (to cover gas fee in C++ test) * Remote state reads nonce check (#959) * Added nonce check * Tests for nonce > 0 || balance > 0 * New syntax for address types and remote state reads. (#960) * Added nonce check * Tests for nonce > 0 || balance > 0 * Changed remote read operator from <-- to <-& * Change address type syntax * Remove _this_address production from address_type_field * Remove _this_address from Address AST nodes * make fmt * Change nonce_type to Uint64 (#961) * Scilla-server wrapper for the disambiguation tool (#964) * Disambiguator should output init JSON to file (#965) * Ignore _balance output (#966) * Remote state reads checker tests (#963) * Equality tests on address types * Non-storable types not allowed in address fields. Contract parameters checked for serializability. eq tests on addresses * Address list traversal tests * Namespaces not allowed when remote reading * Polymorphic address types * Test remote read from non-address * Additional negative remote read tests * Test of deep remote reads * Various deep remote reads tests * Fix problem map builtins on maps with addresses as key types * Only address argument types to put should be converted to ByStr20 * fmt * Merge fixes * fmt * Additional tests of assignability (#962) * Fix contract parameter validation check (#969) * Disable check. Another check needs to be enabled before merging * Allow maps as contract parameters * Validate contract parameters * fmt * Fixed elaboration of to_string, strrev and to_ascii for address types (#971) * Handle migration of contracts with missing state (#972) * Handle migration of contracts with missing state * fmt * Make contract init tests aware of scilla server tests Co-authored-by: Vaivaswatha N <vaivaswatha@users.noreply.github.com> Co-authored-by: Vaivaswatha Nagaraj <vaivaswatha@zilliqa.com>
