From b9ceda38a6a2fd6d4178f0d95ee8fa7f068ab3f9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Tomasz=20Drwi=C4=99ga?= Date: Mon, 7 May 2018 20:17:28 +0200 Subject: [PATCH] [stable] Backports (#8557) * Update wasmi and pwasm-utils (#8493) * Update wasmi to 0.2 New wasmi supports 32bit platforms and no longer requires a special feature to build for such platforms. * Update pwasm-utils to 0.1.5 * Fetching logs by hash in blockchain database (#8463) * Fetch logs by hash in blockchain database * Fix tests * Add unit test for branch block logs fetching * Add docs that blocks must already be sorted * Handle branch block cases properly * typo: empty -> is_empty * Remove return_empty_if_none by using a closure * Use BTreeSet to avoid sorting again * Move is_canon to BlockChain * typo: pass value by reference * Use loop and wrap inside blocks to simplify the code Borrowed from https://github.com/paritytech/parity/pull/8463#discussion_r183453326 * typo: missed a comment * Pass on storage keys tracing to handle the case when it is not modified (#8491) * Pass on storage keys even if it is not modified * typo: account and storage query `to_pod_diff` builds both `touched_addresses` merge and storage keys merge. * Fix tests * Use state query directly because of suicided accounts * Fix a RefCell borrow issue * Add tests for unmodified storage trace * Address grumbles * typo: remove unwanted empty line * ensure_cached compiles with the original signature * Enable WebAssembly and Byzantium for Ellaism (#8520) * Enable WebAssembly and Byzantium for Ellaism * Fix indentation * Remove empty lines * Fix compilation. --- Cargo.lock | 19 ++-- ethcore/res/ethereum/ellaism.json | 17 +++- ethcore/src/blockchain/blockchain.rs | 60 ++++++++++-- ethcore/src/client/client.rs | 92 ++++++++++++++---- ethcore/src/state/mod.rs | 116 +++++++++++++++++------ ethcore/src/verification/verification.rs | 2 +- ethcore/wasm/Cargo.toml | 2 +- 7 files changed, 245 insertions(+), 63 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 0677d6efa..233e90ea6 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1677,6 +1677,11 @@ dependencies = [ "tiny-keccak 1.4.1 (registry+https://github.com/rust-lang/crates.io-index)", ] +[[package]] +name = "nan-preserving-float" +version = "0.1.0" +source = "registry+https://github.com/rust-lang/crates.io-index" + [[package]] name = "net2" version = "0.2.31" @@ -2485,7 +2490,7 @@ dependencies = [ [[package]] name = "pwasm-utils" -version = "0.1.3" +version = "0.1.5" source = "registry+https://github.com/rust-lang/crates.io-index" dependencies = [ "byteorder 1.2.1 (registry+https://github.com/rust-lang/crates.io-index)", @@ -3433,18 +3438,19 @@ dependencies = [ "libc 0.2.36 (registry+https://github.com/rust-lang/crates.io-index)", "log 0.3.9 (registry+https://github.com/rust-lang/crates.io-index)", "parity-wasm 0.27.5 (registry+https://github.com/rust-lang/crates.io-index)", -
