From 249a1e6d8d129d6b067a4ddadfb4b94733ddfc07 Mon Sep 17 00:00:00 2001 From: Greg Hysen Date: Thu, 31 May 2018 16:31:00 -0700 Subject: Removed the LibAssetProxyDecoder. Merged decode functions into the proxies. This way they can still be used by the forwarding contract. TestAssetDataDecoders inherits them in the same way the forwarding contract would --- packages/contracts/compiler.json | 2 +- packages/contracts/package.json | 2 +- .../current/protocol/AssetProxy/ERC20Proxy.sol | 24 ++++++- .../current/protocol/AssetProxy/ERC721Proxy.sol | 29 ++++++++- .../TestAssetDataDecoders.sol | 52 +++++++++++++++ .../TestLibAssetProxyDecoder.sol | 50 --------------- .../LibAssetProxyDecoder/LibAssetProxyDecoder.sol | 74 ---------------------- packages/contracts/src/utils/artifacts.ts | 4 +- packages/contracts/src/utils/types.ts | 2 +- packages/contracts/test/asset_proxy/decoder.ts | 10 +-- 10 files changed, 109 insertions(+), 140 deletions(-) create mode 100644 packages/contracts/src/contracts/current/test/TestAssetDataDecoders/TestAssetDataDecoders.sol delete mode 100644 packages/contracts/src/contracts/current/test/TestLibAssetProxyDecoder/TestLibAssetProxyDecoder.sol delete mode 100644 packages/contracts/src/contracts/current/utils/LibAssetProxyDecoder/LibAssetProxyDecoder.sol diff --git a/packages/contracts/compiler.json b/packages/contracts/compiler.json index 464137d9b..6ef8e6a95 100644 --- a/packages/contracts/compiler.json +++ b/packages/contracts/compiler.json @@ -29,7 +29,7 @@ "MixinAuthorizable", "MultiSigWallet", "MultiSigWalletWithTimeLock", - "TestLibAssetProxyDecoder", + "TestAssetDataDecoders", "TestAssetProxyDispatcher", "TestLibBytes", "TestLibMem", diff --git a/packages/contracts/package.json b/packages/contracts/package.json index 658f5ed60..e436ae15e 100644 --- a/packages/contracts/package.json +++ b/packages/contracts/package.json @@ -30,7 +30,7 @@ "test:circleci": "yarn test" }, "config": { - "abis": "../migrations/artifacts/2.0.0/@(AssetProxyOwner|DummyERC20Token|DummyERC721Token|DummyERC721Receiver|ERC20Proxy|ERC721Proxy|Exchange|MixinAuthorizable|MultiSigWallet|MultiSigWalletWithTimeLock|TestAssetProxyDispatcher|TestLibAssetProxyDecoder|TestLibBytes|TestLibMem|TestLibs|TestSignatureValidator|TokenRegistry|Whitelist|WETH9|ZRXToken).json" + "abis": "../migrations/artifacts/2.0.0/@(AssetProxyOwner|DummyERC20Token|DummyERC721Token|DummyERC721Receiver|ERC20Proxy|ERC721Proxy|Exchange|MixinAuthorizable|MultiSigWallet|MultiSigWalletWithTimeLock|TestAssetDataDecoders|TestAssetProxyDispatcher|TestLibBytes|TestLibMem|TestLibs|TestSignatureValidator|TokenRegistry|Whitelist|WETH9|ZRXToken).json" }, "repository": { "type": "git", diff --git a/packages/contracts/src/contracts/current/protocol/AssetProxy/ERC20Proxy.sol b/packages/contracts/src/contracts/current/protocol/AssetProxy/ERC20Proxy.sol index 5b4367fd9..11383adaf 100644 --- a/packages/contracts/src/contracts/current/protocol/AssetProxy/ERC20Proxy.sol +++ b/packages/contracts/src/contracts/current/protocol/AssetProxy/ERC20Proxy.sol @@ -20,14 +20,13 @@ pragma solidity ^0.4.24;
