Publishing a Release
2+
====================
3+
4+
Check the setup.py version.
5+
Commit and push everything.
6+
Activate the 3.6 venv (to get twine, wheel, etc)
7+
Run: rm -rf dist
8+
Run: python setup.py sdist
9+
Run: python setup.py bdist_wheel --universal
10+
Run: twine upload dist/*
11+
Run: git tag v$VERSION
12+
Run: git push --tags
13+
Go to GitHub and make a release
14+
Bump the setup.py version for next time, and commit.
15+
16+
Control Protocol
17+
================
18+
19+
The control protocol is used between the language APIs (including the
20+
CLI) and the agent. It enables the API clients to control the agent,
21+
creating and using client (initiator) and server (responder) FIX peers.
22+
23+
The agent is controled via one or more TCP sessions. The message
24+
format used over this TCP session is as follows:
25+
26+
Each message consists of a framing header and a payload.
27+
28+
The framing header is a 4 byte big-endian integer number of bytes in
29+
the payload. That is, the number of bytes following the header in this
30+
message. The total TCP payload length will be this value, plus four.
31+
32+
The payload is JSON. Each message must contain:
33+
* the "type" field, a string, being the type of this message
34+
* the "name" field, a string, identifying the entity to which the message
35+
applies
36+
37+
Response messages, returned from the agent to the APIs will also contain:
38+
* the "result" field, a boolean, indicating the success (or failure) of
39+
their matching request.
40+
* the "message" field, a string, describing the error if there was one.
41+
42+
FIX messages are transported as a JSON string. JSON requires strings to
43+
be valid UTF8, and a FIX message is not that, so they're encoded using
44+
BASE64 before being sent.
45+
46+
47+
So, applications should pass FIX messages to the language APIs as a
48+
formatted byte array.

Introduction
9+
============
10+
11+
This utility provides a means of establishing a connection, using the
12+
FIX protocol, with an existing FIX application. The connection is made
13+
from a background agent process, but controlled by either a command-line
14+
tool, or a programming language API.
15+
16+
It is intended for use in either ad-hoc FIX testing (using the command-line)
17+
or for integration testing of FIX applications, where it can be configured
18+
to simulate the intended FIX peer. To automate testing, an existing
19+
language unit testing framework is helpful: test cases can be written to
20+
exercise your code, and interleaved with that you can drive the FIX peer
21+
to confirm receipt of appropriate messages from your application, and to
22+
craft responses (both correct and incorrect) to implement your testing
23+
scenarios.
24+
25+
The agent process communicates with the command-line tool and programming
26+
language APIs using a TCP session. The protocol is simple, and uses
27+
JSON-formatted messages.
28+
29+
Language SDKs are planned for Python, Java, DotNET, and possibly Go and
30+
C/C++. The command-line client enables use from shell scripts or ad-hoc
31+
use from a shell session.
32+
33+
Caveats
34+
=======
35+
36+
This project is very young. It's nowhere near finished. It probably
37+
doesn't do what you need yet.
