+## v3.1.1 - _July 24, 2019_
+
+    * Python method parameters are now in snake case (#1919)
+    * Python wrappers now support tuples in method parameters (#1919)
+    * document Python method's bytes params as requiring UTF-8 (#1919)
+    * generate Python output into a contract-named folder, not a file (eg exchange/__init__.py rather than exchange.py) leaving space for user-defined additions to the same module, such as for custom types, as used by the Exchange wrapper's manually-written type aliases in the contract_wrappers.exchange.types Python module (#1919)
+    * support for customizable parameter validation for Python wrappers (#1919)
+    * wrap Python docstrings better, for pydocstyle compliance (#1919)
+    * lots of fixes to satisfy linters of generated Python code (#1919)

-## @0x/react-docs
-
-#### WARNING: Alpha software. Expect things to break when trying to use.
-
-A full-page React component for rendering beautiful documentation for Solidity and Typescript code generated with [TypeDoc](http://typedoc.org/) or [sol-doc](https://github.com/0xProject/0x-monorepo/tree/development/packages/sol-doc).
-
-<div style="text-align: center;">
-<img src="https://s3.eu-west-2.amazonaws.com/0x-wiki-images/screenshot.png" style="padding-bottom: 20px; padding-top: 20px;" width="80%" />
-<div>react-docs generating 0x's smart contract docs</div>
-</div>
-
-#### Features
-
--   Mobile optimized
--   Reads Javadoc-style comments in your code to generate class/method/argument/return/type comments.
--   Syntax highlighting support for TypeScript & Solidity
--   Type declaration linking
--   Type declaration popovers to avoid clicking through to the definition
--   Section/method/type anchors for easily pointing others to a specific part of your docs.
--   Version picker
--   Customizable sidebar header
--   Supports custom markdown sections so you can easily add an intro or installation instructions.
-
-## Installation
-
-```bash
-yarn add @0x/react-docs
-```
-
-## Usage
-
-This package exposes both a single `Documentation` react component that will render a docs page, as well as all of it's sub-components in case someone wants to build their own layout.
-
-Currently this package still has some external dependencies outside of the `Documentation` component, so please start your project off by copying the [react-docs-example](https://github.com/0xProject/0x-monorepo/tree/development/packages/react-docs-example) directory and modifying it there. If you need changes in the [react-docs](https://github.com/0xProject/0x-monorepo/tree/development/packages/react-docs) package, fork the 0x monorepo, make the required changes and submit a PR. Until we merge it, you can have your project depend on your own custom fork.
-
-If your project is in [TypeScript](https://www.typescriptlang.org/), add the following to your `tsconfig.json`:
-
-```json
-"compilerOptions": {
-    "typeRoots": ["node_modules/@0x/typescript-typings/types", "node_modules/@types"],
-}
-```
-
-## Future improvements
-
-Feel free to contribute to these improvements!
-
--   Allow user to pass in styling for all major elements similar to [Material-UI](http://www.material-ui.com/).
--   Allow user to define an alternative font and have it change everywhere.
--   Add source links to Solidity docs (currently unsupported by solc, which underlies sol-doc).

Subject: [PATCH 082/162] Python nested wrapper methods & estimate_gas (#1996)

* git rm unnecessary .gitkeep file

* After all Pytest runs, show short test summary

* abi-gen/Py: facilitate inlining of parameter lists

Effectively, stopped new-lines from being introduced by calls to the
`params` and `typed_params` partials.

* abi-gen: simple Py wrapper test for local dev'ment

* abi-gen/Py: stop gen'ing ValidatorBase

* abi-gen/Py: declare abi() wrapper method in Base

* abi-gen/Py: methods as classes to ease call/sendTx

Represent methods as classes in order to faciliate access to a method's
different operations (call, send_transaction, etc).

* contract_wrappers.py: make Base methods public

Changed some methods on BaseContractWrapper to be public.

* contract_wrappers.py: remove unused method

* contract_wrappers.py: extract method

* abi-gen/Py: inline method

* contract_wrappers.py: fix bug in call()

We were passing transaction parameters through to sendTransaction()
invocations, but not to call() invocations.

* abi-gen/Py: remove `view_only` param to call/tx

Formerly, in the BaseContractWrapper, there was just one function used
for both eth_call and eth_sendTransaction, and you would distinguish
between the two by specifying `view_only=True` when you wanted a call.

This commit defines a method dedicated to executing an eth_call, and
leaves the old method behind, with the `view_only` param removed, to be
used for eth_sendTransaction.

* abi-gen/Py: rename method

* contract_wrappers/Py: simplify web3 func handling

Pass web3 function instance into generated wrapper method class
constructor, rather than having that class obtain it upon each method
call.

Really this is just an elimination of a call to
BaseContractWrapper.contract_instance(), which will be removed
completely in a shortly-upcoming commit.

* contract_wrappers.py: inline method

Inline and remove method BaseContractWrapper.contract_instance().

* contract_wrappers.py: pass Validator to *Method

Pass a ValidatorBase instance into construction of the contract method
classes, *Method, to eliminate another dependency on the containing
contract object, which will be eliminated completely in a
shortly-upcoming commit.

* abi-gen/Py: BaseContractWrapper -> ContractMethod

Change the fundamental thing-to-be-wrapped from the contract to the
method.  Since the named method classes were introduced (in a previous
commit), and since the operations contained within the Base are
predominantly focused on supporting method calls more than anything
else, it makes more intuitive sense to provide a base for the methods
than for the contract.

With this change, the method classes no longer require a contract object
to be passed to their constructors.  The contract members that the
methods were utilizing are now passed directly to the method
constructor.

* contract_wrappers.py: rename module to bases...

...from _base_contract_wrapper.  The old name hasn't made sense since
ValidatorBase was moved into that module, and definitely doesn't make
sense now that the fundamental thing-to-be-wrapped has changed from the
contract to the method.  Also renamed to make it public (removed the
leading underscore) since we're generating code that will depend on it.

* abi-gen/Py: clarify call/sendTx docstrings

* abi-gen/Py: adjust whitespace

* contract_wrappers.py: inline method

* abi-gen/Py: rename class ValidatorBase...

...to just Validator.  It's in the "bases" module, which provides the
context needed in order to know it's a base class

* python-packages: fix silent failures of ./parallel

* contract_wrappers.py: remove private_key support

Having this present was overcomplicating interfaces.  And it was
untested (and not readily working when testing was attempted).  And it
only provided a thin layer of convenience, which a client could easily
code up themselves.

* contract_wrappers.py: inline method

* contract_wrappers.py: rm unused member variables

* contract_wrappers.py: rm unnecessary instance var

* abi-gen/Py: add estimate_gas to gen'd methods

* update CHANGELOG.json

+### Documentation
+
+Documentation for this package is generated by TypeDoc, using the Solidity source code for 0x contracts. Each contract corresponds to one global-level module, which contains relevant enums and interfaces for its events and structs. Most significantly, each module exports a class, `<ContractName>Contract`, e.g. `ExchangeContract`, which implements helper methods for all the functions defined in the corresponding contract.
+
+A convention to note is that these contract-specific helper methods are defined as _object literals_, which are separated from methods in the generated documentation. Each contract method has a number of sub-methods, e.g. `sendTransactionAsync`, or `estimateGasAsync`, which are documented separately. This is an example of an expected method call signature: `exchangeContractInstance.fillOrder.sendTransactionAsync(...arguments)`.

Subject: [PATCH 114/162] Generate wrappers for all contracts (#2010)

* abi-gen/Py: fix return type for multi-val returns

Methods that return multiple values were broken in two ways.  One: a
spurious newline was being injected between the return type and the
colon ending the Python method prototype.  Two: the return type was
being generated as just `[TypeA, TypeB]`, whereas it should be
`Tuple[TypeA, TypeB]`.

* abi-gen/Py: fix support for arrays of structs

* abi-gen/Py: FAILING test case nested unrefd struct

When a struct contains another struct, and the inner struct is not
directly referenced by any method interface, wrapper generation is
failing to render a class to represent the inner struct.

This won't fail in CI because at this time CI doesn't run any native
Python tooling to analyze the generated code.  Running mypy locally on
the files in this commit produces the following output:

test-cli/output/python/abi_gen_dummy/__init__.py:76: error: Name 'Tuple0x246f9407' is not defined

This problem affects the generation of wrappers for the DutchAuction
contract.

* abi-gen/Py: fix nested unref'd struct failure

* abi-gen/Py: introduce newlines to quiet linter

When generating contracts with long names (eg
CoordinatorRegistryValidator), the `black` reformatter was introducing
these newlines for us, and it was moving the `# type: ignore` comment in
there such that it no longer was on the line it needed to be on.
Introducing these newlines manually (instead of letting black inject
them) allows the linter directive to stay where it needs to be.

* abi-gen/Py: declare tuples in dependency order

* abi-gen/Py: fix support for overloaded methods

* contract_wrappers.py: pylint: permit 2-char args

By default pylint says that 2 characters is too short for an argument
name, but we have some contract methods with 2-character argument names
(eg `to` in `AssetProxyOwner.getTransactionIds()`), so we want to permit
them.

* contract_wrappers.py: include all contracts

* Update CHANGELOGs

* abi-gen: rename variable

* abi-gen: refine comments

* abi-gen/Py: reword tuple class docstring

+### Documentation
+
+Documentation for this package is generated by TypeDoc, using the Solidity source code for 0x contracts. Each contract corresponds to one global-level module, which contains relevant enums and interfaces for its events and structs. Most significantly, each module exports a class, `<ContractName>Contract`, e.g. `ExchangeContract`, which implements helper methods for all the functions defined in the corresponding contract.
+
+A convention to note is that these contract-specific helper methods are defined as _object literals_, which are separated from methods in the generated documentation. Each contract method has a number of sub-methods, e.g. `sendTransactionAsync`, or `estimateGasAsync`, which are documented separately. This is an example of an expected method call signature: `exchangeContractInstance.fillOrder.sendTransactionAsync(...arguments)`.

 CHANGELOG
 
+## v4.1.0 - _August 8, 2019_
+
+    * Updated expected typescript output for cli tests to include `getABIDecodedTransactionData` and `getABIDecodedReturnData` (#2018)
+    * Added tests for`getABIDecodedTransactionData` and `getABIDecodedReturnData` in contract wrappers. (#2018)
+
+## v4.0.0 - _Invalid date_
+
+    * whitespace changes to generated Python code (#1996)
+    * move Python Validator base class from generated code to common package (#1996)
+    * Changed fundamental thing-to-be-wrapped from the contract to the contract method.  That is, now there is a base contract method wrapper class rather than a base contract wrapper class, and individual contract methods are represented by named classes inheriting from that base, and the different operations on a method are now represented by a nested-object dot notation, ie, WrappedContract.ContractMethod.call() and WrappedContract.ContractMethod.send_transaction(). (#1996)
+    * added gas estimation functionality to contract methods (#1996)
+    * Python: fixed bug with methods returning multiple values (#1996)
+    * Python: fixed bug with methods returning arrays of structs (#1996)
+    * Python: fixed bug with methods that return a struct that contains another struct where the inner struct was not otherwise directly referenced by any method (#1996)
+    * Python: fixed bug with tuples sometimes being used before they were declared (#1996)
+    * Python: fixed bug with supporting overloaded methods (#1996)
+

 CHANGELOG
 
-## v4.1.0 - _August 8, 2019_
-
-    * Updated expected typescript output for cli tests to include `getABIDecodedTransactionData` and `getABIDecodedReturnData` (#2018)
-    * Added tests for`getABIDecodedTransactionData` and `getABIDecodedReturnData` in contract wrappers. (#2018)
-
-## v4.0.0 - _Invalid date_
-
-    * whitespace changes to generated Python code (#1996)
-    * move Python Validator base class from generated code to common package (#1996)
-    * Changed fundamental thing-to-be-wrapped from the contract to the contract method.  That is, now there is a base contract method wrapper class rather than a base contract wrapper class, and individual contract methods are represented by named classes inheriting from that base, and the different operations on a method are now represented by a nested-object dot notation, ie, WrappedContract.ContractMethod.call() and WrappedContract.ContractMethod.send_transaction(). (#1996)
-    * added gas estimation functionality to contract methods (#1996)
-    * Python: fixed bug with methods returning multiple values (#1996)
-    * Python: fixed bug with methods returning arrays of structs (#1996)
-    * Python: fixed bug with methods that return a struct that contains another struct where the inner struct was not otherwise directly referenced by any method (#1996)
-    * Python: fixed bug with tuples sometimes being used before they were declared (#1996)
-    * Python: fixed bug with supporting overloaded methods (#1996)
-
 ## v3.1.2 - _July 31, 2019_
 
     * Dependencies updated

+## v4.1.0 - _August 8, 2019_
+
+    * Updated expected typescript output for cli tests to include `getABIDecodedTransactionData` and `getABIDecodedReturnData` (#2018)
+    * Added tests for`getABIDecodedTransactionData` and `getABIDecodedReturnData` in contract wrappers. (#2018)
+
+## v4.0.0 - _Invalid date_
+
+    * whitespace changes to generated Python code (#1996)
+    * move Python Validator base class from generated code to common package (#1996)
+    * Changed fundamental thing-to-be-wrapped from the contract to the contract method.  That is, now there is a base contract method wrapper class rather than a base contract wrapper class, and individual contract methods are represented by named classes inheriting from that base, and the different operations on a method are now represented by a nested-object dot notation, ie, WrappedContract.ContractMethod.call() and WrappedContract.ContractMethod.send_transaction(). (#1996)
+    * added gas estimation functionality to contract methods (#1996)
+    * Python: fixed bug with methods returning multiple values (#1996)
+    * Python: fixed bug with methods returning arrays of structs (#1996)
+    * Python: fixed bug with methods that return a struct that contains another struct where the inner struct was not otherwise directly referenced by any method (#1996)
+    * Python: fixed bug with tuples sometimes being used before they were declared (#1996)
+    * Python: fixed bug with supporting overloaded methods (#1996)

-## v4.1.0 - _August 8, 2019_
-
-    * Updated expected typescript output for cli tests to include `getABIDecodedTransactionData` and `getABIDecodedReturnData` (#2018)
-    * Added tests for`getABIDecodedTransactionData` and `getABIDecodedReturnData` in contract wrappers. (#2018)
-
-## v4.0.0 - _Invalid date_
-
-    * whitespace changes to generated Python code (#1996)
-    * move Python Validator base class from generated code to common package (#1996)
-    * Changed fundamental thing-to-be-wrapped from the contract to the contract method.  That is, now there is a base contract method wrapper class rather than a base contract wrapper class, and individual contract methods are represented by named classes inheriting from that base, and the different operations on a method are now represented by a nested-object dot notation, ie, WrappedContract.ContractMethod.call() and WrappedContract.ContractMethod.send_transaction(). (#1996)
-    * added gas estimation functionality to contract methods (#1996)
-    * Python: fixed bug with methods returning multiple values (#1996)
-    * Python: fixed bug with methods returning arrays of structs (#1996)
-    * Python: fixed bug with methods that return a struct that contains another struct where the inner struct was not otherwise directly referenced by any method (#1996)
-    * Python: fixed bug with tuples sometimes being used before they were declared (#1996)
-    * Python: fixed bug with supporting overloaded methods (#1996)
-

Subject: [PATCH 127/162] Migrate to Web3.py v5 (#2038)

* Install Py packages in dep. order, not in parallel

Install Python packages in dependency order, not in parallel.

* sra_client.py: Add `./setup.py clean`

* Fix python package dependency ordering...

...and include a script to produce the proper ordering.

* sra_client.py: reformat whitespace in doctest

* contract_wrappers.py: don't auto-import wrappers

This was discovered while minimizing CircleCI steps to dianose a problem
with running the Launch Kit Backend in CircleCI.

These classes should be imported via the
zero_ex.contract_wrappers.exchange and
zero_ex.contract_wrappers.erc20_token modules, respectively.  We
permitted importing them from just zero_ex.contract_wrappers back when
they were the only wrappers we had, but now that we have so many
different contracts being wrapped, this is just another list to keep
manually updated (which, obviously is error prone, since it slipped
through the cracks already), so it's better to just not support this
type of import.

* abi-gen/Py: doc contract method attributes

Without this, generated documentation was not including the class
members that represent the contract methods, rendering the usage
unclear.

* sra_client.py: disable tests in CI

* abi-gen/Py: strip repeated spaces from devdoc

* contract_wrappers.py: gen docs for all wrappers...

...except for the dummy tokens.

* sra_client.py/test: change launch kit docker image

Previously these teses were using 0xorg/launch-kit-ci, but that was a
one-off thing created just for CI, back before there was a regularly
maintained docker image of Launch Kit.

Changed to use 0xorg/launch-kit-backend since it's regularly
maintained/updated.

Because the -backend image is using a different Linux distribution
(Alpine), the commands used to wait for ganache startup also had to
change.

The tag used, 74bcc39, is provisional due to the pending Issue at
https://github.com/0xProject/0x-launch-kit-backend/issues/73 .  When
that issue is resolved, the tag suffix on the imag name should be
removed.

* Migrate from Web3.py 4.x to 5.x

* sra_client.py: checksum address in doctest

Due to problem with launch-kit-backend, documented at
https://github.com/0xProject/0x-launch-kit-backend/issues/73 ,
we need to checksum the makerAddress, in the order retrieved from the
relayer, before filling it, otherwise Web3.py gives this error:

InvalidAddress('Web3.py only accepts checksum addresses. The software
that gave you this non-checksum address should be considered unsafe,
please file it as a bug on their platform. Try using an ENS name

+## v4.1.0 - _August 8, 2019_
+
+    * Updated expected typescript output for cli tests to include `getABIDecodedTransactionData` and `getABIDecodedReturnData` (#2018)
+    * Added tests for`getABIDecodedTransactionData` and `getABIDecodedReturnData` in contract wrappers. (#2018)
+
+## v4.0.0 - _Invalid date_
+
+    * whitespace changes to generated Python code (#1996)
+    * move Python Validator base class from generated code to common package (#1996)
+    * Changed fundamental thing-to-be-wrapped from the contract to the contract method.  That is, now there is a base contract method wrapper class rather than a base contract wrapper class, and individual contract methods are represented by named classes inheriting from that base, and the different operations on a method are now represented by a nested-object dot notation, ie, WrappedContract.ContractMethod.call() and WrappedContract.ContractMethod.send_transaction(). (#1996)
+    * added gas estimation functionality to contract methods (#1996)
+    * Python: fixed bug with methods returning multiple values (#1996)
+    * Python: fixed bug with methods returning arrays of structs (#1996)
+    * Python: fixed bug with methods that return a struct that contains another struct where the inner struct was not otherwise directly referenced by any method (#1996)
+    * Python: fixed bug with tuples sometimes being used before they were declared (#1996)
+    * Python: fixed bug with supporting overloaded methods (#1996)

Subject: [PATCH 138/162] Pre-publish version updates (#2049)

* json_schemas.py: make changelog be rev. chrono.

Change CHANGELOG.md from chronological to reverse chronological.

* json_schemas.py: fix version numbers

It looks like the version number was changed in the past, but the new
version was never published, so corrected that.  Will publish after this
merges into development.

* order_utils.py: pre-publish version bump

 # Changelog
 
+## 3.0.1 - 2019-08-09
+
+-   Fixed dependencies: changed `deprecated` from being an extras_require["dev"] dependency to being an install_requires dependency, since it's required not just for doc generation but also just to import the package.
+
 ## 3.0.0 - 2019-08-08
 
 -   Major breaking changes: removal of definitions for Order, OrderInfo, order_to_jsdict, jsdict_to_order, all of which have been moved to contract_wrappers.exchange.types; removal of signature validation; migration from v4 to v5 of Web3.py

Subject: [PATCH 148/162] Fixes for broken `tox` runs (#2053)

* order_utils.py: git rm package.json

This was used at one time, a long, long time ago, but is no longer used,
and its presence actually causes problems when trying to do, eg
`PKG=@0x/python-contract-wrappers yarn build` from within the
order_utils directory.

* order_utils.py: improve `./setup.py clean`

* python-packages: in tox, test, don't lint

* python-packages: update dev req's to fix tox runs

* contract_wrappers.py: post-publish version bump

The update to the fixture contract's artifact added a bunch of
`internalType` stuff.  I'm not sure where that came from.  Maybe
newly generated by the latest version of solc?

-## OrderWatcher [Deprecated]
-
-:no_entry: WARNING: This project is deprecated. Please use [0x Mesh](https://github.com/0xProject/0x-mesh) for all your orderbook pruning needs. It can be used with or without order sharing enabled. If you have any questions about how to use Mesh, reach out to us in the [#mesh channel on Discord](https://discordapp.com/invite/d3FTX3M) :no_entry:
-
-An order watcher daemon that watches for order validity.
-
-#### Read the wiki [article](https://0xproject.com/wiki#0x-OrderWatcher).
-
-OrderWatcher also comes with a WebSocket server to provide language-agnostic access
-to order watching functionality. We used the [WebSocket Client and Server Implementation for Node](https://www.npmjs.com/package/websocket). The server sends and receives messages that conform to the [JSON RPC specifications](https://www.jsonrpc.org/specification).
-
-## Installation
-
-**Install**
-
-```bash
-npm install @0x/order-watcher --save
-```
-
-**Import**
-
-```javascript
-import { OrderWatcher } from '@0x/order-watcher';
-```
-
-If your project is in [TypeScript](https://www.typescriptlang.org/), add the following to your `tsconfig.json`:
-
-```json
-"compilerOptions": {
-    "typeRoots": ["node_modules/@0x/typescript-typings/types", "node_modules/@types"],
-}
-```
-
-## Using the WebSocket Server
-
-**Setup**
-
-**Environmental Variables**
-Several environmental variables can be set to configure the server:
-
--   `ORDER_WATCHER_HTTP_PORT` specifies the port that the http server will listen on
-    and accept connections from. When this is not set, we default to 8080.
-
-**Requests**
-The server accepts three types of requests: `ADD_ORDER`, `REMOVE_ORDER` and `GET_STATS`. These mirror what the underlying OrderWatcher does. You can read more in the [wiki](https://0xproject.com/wiki#0x-OrderWatcher). Unlike the OrderWatcher, it does not expose any `subscribe` or `unsubscribe` functionality because the WebSocket server keeps a single subscription open for all clients.
-
-The first step for making a request is establishing a connection with the server. In Javascript:
-
-```
-var W3CWebSocket = require('websocket').w3cwebsocket;
-wsClient = new W3CWebSocket('ws://127.0.0.1:8080');
-```
-
-In Python, you could use the [websocket-client library](http://pypi.python.org/pypi/websocket-client/) and run:
-
-```
-from websocket import create_connection
-wsClient = create_connection("ws://127.0.0.1:8080")
-```
-
-With the connection established, you prepare the payload for your request. The payload is a json object with a format established by the [JSON RPC specification](https://www.jsonrpc.org/specification):
-
--   `id`: All requests require you to specify a numerical `id`. When the server responds to the request, the response will have the same `id` as the one supplied with your request.
--   `jsonrpc`: This is always the string `'2.0'`.
--   `method`: This specifies the OrderWatcher method you want to call. I.e., `'ADD_ORDER'`, `'REMOVE_ORDER'` or `'GET_STATS'`.
--   `params`: These contain the parameters needed by OrderWatcher to execute the method you called. For `ADD_ORDER`, provide `{ signedOrder: <your signedOrder> }`. For `REMOVE_ORDER`, provide `{ orderHash: <your orderHash> }`. For `GET_STATS`, no parameters are needed, so you may leave this empty.
-
-Next, convert the payload to a string and send it through the connection.
-In Javascript:
-
-```
-const addOrderPayload = {
-    id: 1,
-    jsonrpc: '2.0',
-    method: 'ADD_ORDER',
-    params: { signedOrder: <your signedOrder> },
-};
-wsClient.send(JSON.stringify(addOrderPayload));
-```
-
-In Python:
-
-```
-import json
-remove_order_payload = {
-    'id': 1,
-    'jsonrpc': '2.0',
-    'method': 'REMOVE_ORDER',
-    'params': {'orderHash': '0x6edc16bf37fde79f5012088c33784c730e2f103d9ab1caf73060c386ad107b7e'},
-}
-wsClient.send(json.dumps(remove_order_payload));
-```
-
-**Response**
-The server responds to all requests in a similar format. In the data field, you'll find another object containing the following fields:
-
--   `id`: The id corresponding to the request that the server is responding to. `UPDATE` responses are not based on any requests so the `id` field is omitted`.
--   `jsonrpc`: Always `'2.0'`.
--   `method`: The method the server is responding to. Eg. `ADD_ORDER`. When order states change the server may also initiate a response. In this case, method will be listed as `UPDATE`.
--   `result`: This field varies based on the method. `UPDATE` responses contain the new order state. `GET_STATS` responses contain the current order count. When there are errors, this field is omitted.
--   `error`: When there is an error executing a request, the [JSON RPC](https://www.jsonrpc.org/specification) error object is listed here. When the server responds successfully, this field is omitted.
-
-In Javascript, the responses can be parsed using the `onmessage` callback:
-
-```
-wsClient.onmessage = (msg) => {
-    const responseData = JSON.parse(msg.data);
-    const method = responseData.method
-};
-```
-
-In Python, `recv` is a lightweight way to receive a response:
-
-```
-result = wsClient.recv()
-method = result.method

 In v2 of the standard relayer API we added the `metaData` field. It is meant to provide a standard place for relayers to put optional, custom or non-standard fields that may of interest to the consumer of the API.
 
-A good example of such a field is `remainingTakerAssetAmount`, which is a convenience field that communicates how much of a 0x order is potentially left to be filled. Unlike the other fields in a 0x order, it is not guaranteed to be correct as it is derived from whatever mechanism the implementer (ie. the relayer) is using. While convenient for prototyping and low stakes situations, we recommend validating the value of the field by checking the state of the blockchain yourself, such as by using [Order Watcher](https://0xproject.com/wiki#0x-OrderWatcher).

 In v2 of the standard relayer API we added the `metaData` field. It is meant to provide a standard place for relayers to put optional, custom or non-standard fields that may of interest to the consumer of the API.
 
-A good example of such a field is `remainingTakerAssetAmount`, which is a convenience field that communicates how much of a 0x order is potentially left to be filled. Unlike the other fields in a 0x order, it is not guaranteed to be correct as it is derived from whatever mechanism the implementer (ie. the relayer) is using. While convenient for prototyping and low stakes situations, we recommend validating the value of the field by checking the state of the blockchain yourself, such as by using [Order Watcher](https://0xproject.com/wiki#0x-OrderWatcher).

Subject: [PATCH 161/162] Run CI in an environment that includes Python, and
 test generated code (#2072)

* CI: use a docker image that includes Python

So that tests of abi-gen generating Python can exercise the code being
generated.

* CI fix: disable old yarn permission denied hack

Motivated by CI failure of previous commit.

* CI fix: more resources for test-contracts-ganache

Motivated by CI failure of previous commit.

* CI fix: remove hack of permissions for python libs

Fix for previous CI run's failure of test-python.  Apparently we don't
need this in the docker container we've switched to.

* abi-gen/Py: minimum viable test of gen'd code

Ensure the code is parseable by running it through black.

* abi-gen/Py: expand Python linter usage

Make abi-gen filter its output through black, if its available in the
runtime environment.  Accordingly, stop having contract_wrappers.py's
setup.py pre_install run black on copied-over files.

Adds Pylint to the list of linters run against test-cli/output.

* abi-gen: re-enable Solidity linter

It was broken, running seemingly cleanly but not actually reading any
files, because it was targetting the wrong folder.

* abi-gen/test-cli/fixtures/sol: fix linter errors

* abi-gen/test-cli: disable pylint blackisted-name

* abi-gen/Py: rm unused var in contracts w/o methods

Remove unused variable from generated wrapper for contracts without any
methods.
