      Fix key collision for child trie (#4162) · 0ece5d9e
      cheme authored
      * In progress, runtime io must switch to future proof root +
      child_specific (unique id) + u32 type.
      
      * Switch interface, sr-io seems ok, rpc could use similar interface to
      sr-io, genesis json broken if there is child trie in existing encoding
      genesis.
      
      * test from previous implementation.
      
      * fix proving test.
      
      * Restore Keyspacedb from other branch, only apply to child trie.
      
      * Removing unneeded child_info from child root (child info are stored
      if things changed, otherwhise the root does not change).
      
      * Switch rpc to use same format as ext: more future proof.
      
      * use root from child info for trie backend essence.
      
      * Breaking long lines.
      
      * Update doc and clean pr a bit.
      
      * fix error type
      
      * Restore removed doc on merge and update sr-io doc.
      
      * Switch child storage api to use directly unique id, if managed id
      where to be put in place, the api will change at this time.
      
      * Clean deprecated host interface from child.
      
      * Removing assertion on child info (can fail depending on root
      memoization).
      
      * merging child info in the overlay when possible.
      
      * child iteration by prefix using child_info.
      
      * Using ChainInfo in frame support. ChainInfo gets redesign to avoid
      buffers allocation on every calls.
      
      * Add length of root to the data of child info.
      
      * comments
      
      * Encode compact.
      
      * Remove child info with root.
      
      * Fix try_update condition.
      
      * Comment Ext child root caching.
      
      * Replace tuples by struct with field
      
      * remove StorageTuple alias.
      
      * Fix doc tests, and remove StorageOverlay and ChildStorageOverlay
      aliases.

      * Fix compilation
      
      * Catch native panics when executing the wasm runtime
      
      As with the native runtime, we now catch all native panics when we
      execute the wasm runtime. The panics inside the wasm runtime were
      already catched before by the wasm executor automatically, but any panic
      in the host functions could bring down the node. The recent switch to
      execute the native counterpart of the host function in `sr-io`, makes
      this change required. The native `sr-io` functions just `panic` when
      something is not provided or any other error occured.
      
      * Fix compilation
      
      * Don't panic in a panic

      srml-contracts: Contract calls/instantiations to return exit statuses (#3320) · 36abb128
      Jim Posen authored
      * srml-contracts: Rename ext_scratch_copy to ext_scratch_read.
      
      This is to disambiguate from the next ext_scratch_write function.
      
      * Remove unnecessary OutputBuf and EmptyOutputBuf.
      
      * Replace VmExecError with a result type of custom structs.
      
      * Do not drop the scratch buffer on traps and regular returns.
      
      This just reduces the number of allocations required during nested
      contract calls and instantiations.
      
      * Semantics for returning a status code and data from contract calls.
      
      * Remove CallReceipt and InstantiateReceipt.
      
      With forthcoming changes to return data from instantiate calls, the two
      types of receipts become very similar to each other and to
      ExecReturnValue. Instead, replace them with ExecReturnValue and
      a regular 2-tuple in the case of instantiation.
      
      * Modify contract function signatures to allow returning status codes.
      
      * Introduce ext_sandbox_write runtime function.
      
      * Test all the things.
      
      * Bump node runtime spec version.
      
      * Style fixes.

      BABE Randomness using PreRuntime digests (#2929) · 81d8a5d0
      DemiMarie-parity authored
      
      
      * Initial work on exposing pre-runtime digests
      
      This provides the primitive API, as well as exposing it from BABE.
      
      * Initial work on using pre-digests in runtimes
      
      This includes both code to expose them from `srml_system`, as well as
      using it in (currently dead) code in `srml_babe`.
      
      * Bump `{spec,impl}_version`
      
      * Add `u64_backend` feature to curve25519-dalek
      
      Otherwise, it errors out at compile-time.
      
      * Bump `Cargo.lock`
      
      * Do not depend on the schnorrkel crate in the runtime
      
      The schnorrkel crate does not work on `#![no_std]`, but the runtime only
      needs constants from it.  This adds our own definitions of those
      constants, and checks them for correctness at compile-time.
      
      * Actually implement storage of VRF outputs
      
      * Trivial formatting change
      
      * Provide a `hash_randomness` function in BABE
      
      for processing VRF outputs.
      
      * Implement a basic randomness generating function
      
      It just XORs the VRF outputs together.
      
      * Actually implement on-chain randomness
      
      Blake2b is used for hashing.
      
      * Update dependencies
      
      * Run `cargo update` where needed
      
      * Re-add a newline at EOF
      
      * Remove broken and unsafe code
      
      XOR is not a hash function, and must not be used as such.  The
      implementation was also needlessly unsafe.
      
      * Run `cargo update` where needed
      
      * Remove spurious dependency
      
      * Document security guarantees of BABE randomness
      
      * Add a `RandomnessBeacon` trait
      
      * Document `RandomnessBeacon::random`
      
      * Fix silly compile error (unexpected type arguments)
      
      * Fix BABE randomness
      
      * Implement `FindAuthor` for `babe::Module`
      
      * Apply suggestions from code review

      Co-Authored-By: default avatarRobert Habermeier <[email protected]>
      
      * Respond to suggestions from code review and fix bugs
      
      * Store an authority index, not the authority itself.
      * Avoid unnecessary decoding.
      * Implement relative slots and BABE randomness fully and correctly.
      
      * Remove spurious dependency
      
      * Fix error reported by rust-analyzer
      
      * Update Cargo.lock files
      
      * `wrapping_add` → `checked_add`
      
      The epoch index will not overflow.  Panic if it does.
      
      * Move randomness documentation to trait
      
      * Fix compile error in test suite
      
      * Explain 2^64 limit
