* Merge remote-tracking branch 'origin/master' into gav-xts-dont-panic * Update wasm. * consensus, session and staking all panic-safe. * Democracy doesn't panic in apply. * Fix tests. * Extra helper macro, council depanicked. * Fix one test. * Fix up all council tests. No panics! * Council voting depanicked. * Dispatch returns result. * session & staking tests updated * Fix democracy tests. * Fix council tests. * Fix up polkadot parachains in runtime * Fix borked merge * More Slicable support Support general `Option` and array types. * Basic storage types. * Existential deposit for contract creation * Basic implemnetation along with removals * Fix tests. * externalities builder fix. * Tests. * Fix up the runtime. * Fix tests. * Add generic `Address` type. * Initial function integration of Address into Extrinsic. * Fix build * All tests compile. * Fix (some) tests. * Fix signing. * Push error. * transfer can accept Address * Make Address generic over AccountIndex * Fix test * Make Council use Address for dispatch. * Fix build * Bend over backwards to support braindead derive. * Repot some files. * Fix tests. * Fix grumbles * Remove Default bound * Fix build for new nightly. * Make `apply_extrinsic` never panic, return useful Result. * More merge hell * Doesn't build, but might do soon * Serde woes * get substrate-runtime-staking compiling * Polkadot builds again! * Fix all build. * Fix tests & binaries. * Reserve some extra initial byte values of address for future format changes * Make semantic of `ReservedBalance` clear. * Fix panic handler. * Integrate other balance transformations into the new model Fix up staking tests. * Fix runtime tests. * Fix panic build. * Tests for demonstrating interaction between balance types. * Repot some runtime code * Fix checkedblock in non-std builds * Get rid of `DoLookup` phantom. * Attempt to make transaction_pool work with lookups. * Remove vscode settings * New attempt at making transaction pool work. * It builds again! * --all builds * Fix tests. * New build. * Test account nonce reset. * polkadot transaction pool tests/framework. * Initial draft (working). * Address grumbles. * Revert bad `map_or` * Rebuild binaries, workaround. * Avoid checking in vscode * reconnecting, shared, slog * CLI options for name and telemetry url * ensure telemetry url imples enabled * Avoid casting to usize early. * Provide on-connect event for session message * Better port * heartbeat and some renaming * transaction pool stuff * minor renaming. * report telemetry * cleanups. * Fix for previous cleanup * dump genesis, dev mode, renaming * Rework chain spec/config &c. to allow for genesis file loading. * Avoid producing genesis storage when unneeded * Allow reading JSON genesis state dumps * tests work again * better logging. * Fix wasm build. * Introduce PoC-1 spec * Made block message compatible with poc-1 * Squashed changes for dumping genesis block. * Binaries. * Made block message compatible with poc-1 * Remove dead code. * Fix bad merge. * Argument passing and returning values when invoking sandboxed funcs (#189) * Fixed block download sequence (#223) * Trie-based execution proof (#177) * TrieBasedBackend * trie tests * redunant return_value removed * use Trie::get_with to record trie proofs * Relaying tx/blocks by light clients (#190) * do not import external transactions into light tx pool * do not announce blocks on light clients * blocks_are_not_announced_by_light_nodes
