From 1f0c7f8fbeba90ac1f65c57ff58782051c751b3d Mon Sep 17 00:00:00 2001 From: "F. Eugene Aumson" Date: Tue, 23 Oct 2018 12:08:16 -0400 Subject: feat(order_utils.py): ERC20 asset data encoding and decoding In addition to the ERC20 codec, also: Stopped ignoring type errors on 3rd party imports, by including interface stubs for them; Removed the unimplemented signature-utils module, which was just a stand-in when the python project support was first put in place. https://github.com/0xProject/0x-monorepo/pull/1144 --- CODEOWNERS | 1 + packages/order-utils/test/asset_data_utils_test.ts | 31 +++++++ python-packages/order_utils/setup.py | 39 ++++++-- python-packages/order_utils/src/conf.py | 5 +- python-packages/order_utils/src/index.rst | 5 +- .../order_utils/src/zero_ex/dev_utils/__init__.py | 1 + .../order_utils/src/zero_ex/dev_utils/abi_utils.py | 102 +++++++++++++++++++++ .../src/zero_ex/dev_utils/type_assertions.py | 33 +++++++ .../src/zero_ex/order_utils/asset_data_utils.py | 72 +++++++++++++++ .../src/zero_ex/order_utils/signature_utils.py | 13 --- .../order_utils/stubs/distutils/__init__.pyi | 0 .../stubs/distutils/command/__init__.pyi | 0 .../order_utils/stubs/distutils/command/clean.pyi | 7 ++ .../order_utils/stubs/pytest/__init__.pyi | 0 .../order_utils/stubs/pytest/raises.pyi | 1 + .../order_utils/stubs/setuptools/__init__.pyi | 6 ++ .../stubs/setuptools/command/__init__.pyi | 0 .../order_utils/stubs/setuptools/command/test.pyi | 3 + .../order_utils/stubs/web3/__init__.pyi | 10 ++ python-packages/order_utils/test/test_abi_utils.py | 53 +++++++++++ .../order_utils/test/test_asset_data_utils.py | 35 +++++++ python-packages/order_utils/test/test_doctest.py | 22 ++++- .../order_utils/test/test_signature_utils.py | 8 -- 23 files changed, 410 insertions(+), 37 deletions(-) create mode 100644 packages/order-utils/test/asset_data_utils_test.ts mode change 100644 => 100755 python-packages/order_utils/setup.py create mode 100644 python-packages/order_utils/src/zero_ex/dev_utils/__init__.py create mode 100644 python-packages/order_utils/src/zero_ex/dev_utils/abi_utils.py create mode 100644 python-packages/order_utils/src/zero_ex/dev_utils/type_assertions.py create mode 100644 python-packages/order_utils/src/zero_ex/order_utils/asset_data_utils.py delete mode 100644 python-packages/order_utils/src/zero_ex/order_utils/signature_utils.py create mode 100644 python-packages/order_utils/stubs/distutils/__init__.pyi create mode 100644 python-packages/order_utils/stubs/distutils/command/__init__.pyi create mode 100644 python-packages/order_utils/stubs/distutils/command/clean.pyi create mode 100644 python-packages/order_utils/stubs/pytest/__init__.pyi create mode 100644 python-packages/order_utils/stubs/pytest/raises.pyi create mode 100644 python-packages/order_utils/stubs/setuptools/__init__.pyi create mode 100644 python-packages/order_utils/stubs/setuptools/command/__init__.pyi create mode 100644 python-packages/order_utils/stubs/setuptools/command/test.pyi create mode 100644 python-packages/order_utils/stubs/web3/__init__.pyi create mode 100644 python-packages/order_utils/test/test_abi_utils.py create mode 100644 python-packages/order_utils/test/test_asset_data_utils.py delete mode 100644 python-packages/order_utils/test/test_signature_utils.py diff --git a/CODEOWNERS b/CODEOWNERS index 278234aff..ba40af31a 100644 --- a/CODEOWNERS +++ b/CODEOWNERS @@ -26,3 +26,4 @@ packages/subproviders/ @fabioberger @dekz packages/connect/ @fragosti packages/monorepo-scripts/ @fabioberger packages/order-utils/ @fabioberger @LogvinovLeon +python-packages/ @feuGeneA \ No newline at end of file diff --git a/packages/order-utils/test/asset_data_utils_test.ts b/packages/order-utils/test/asset_data_utils_test.ts new file mode 100644 index 000000000..f8b850604 --- /dev/null +++ b/packages/order-utils/test/asset_data_utils_test.ts @@ -0,0 +1,31 @@ +import * as chai from 'chai';
