Hi,
I'm the CTO of a Fintek startup, we require a fix protocol solution and nearing production in a couple of months.

First, congrats!
The project is very impressive! and I think that it's a very important contribution to the open-source community and to the FIX community in particular.

In the next couple of weeks we'll start integration with a sell side broker.

@cbusbey : After seeing this repository we started wondering :

1. Is it ready for production use in your opinion?
2. Are you planning on maintaining it for the next couple of months/year?

Thanks in advance,
Erik.

Reproducible with trade client.

Start the executor or order match
Start the trade client
Stop the executor or order match
Try sending an order from trade client
Trade client panics.

6_SendTestRequest

If a heartbeat is not sent to the target, a test request should be received
and we should eventually timeout

2d_GarbledMessage

The comment on the OnLogout in application.go says Notification of a session logging off or disconnecting., but while I can see in the code that this method will be called on a log out, I don't see it called anywhere when we are disconnected because the other party stopped responding.
I think it's just a matter of adding s.application.OnLogout(s.sessionID) to func (s *Session) onDisconnect() in session.go.

I would really like to get this notification so we can try to reconnect or otherwise take that specific fix connection out of the pool (at least temporarily)

If you want I can send a pull request.

Generate fields for parsinging, writing repeating groups

StartTime, EndTime, StartDay, EndDay...

• start time, end time config (#195)
• a session in the logout state expires when outside of session time (#197,#198)
• a session in the logon state expires when outside of session time (#197,#198)
• a session resets if in session time, but outside of the session creation (#197,#198,#201)
• a session can expire when not running (#200,#202)
• an acceptor will not accept session connections outside of session time (#203)
• an initiator will not attempt a connection outside of session time (#203, #209)
• non-utc time zones (#206)
• start day, end day config for extended sessions (#207)
• documentation (#207)

2i_BeginStringValueUnexpected

constructor should take required fields for the message

The demo trade client does not recover if the executor or order match is not running prior to starting the executor or order match. The initiator should attempt reconnect.

Log files get overridden on every run.

While that's irrelevant in development, it is bad for production.

If message sequence number is too high, send a resend request for
missing messages

2f_PossDupOrigSendingTimeTooHigh

Using gocheck, std unit tests. Would prefer to not have to fetch test deps.

Is there any plan on creating custom dictionary from a custom dictionary as every (if not all) FIX RoE as customized and not fully compliant with the protocol?

2e_PossDupNotReceived

Initiator configuration for supporting alternate hosts for connecting to a session for failover

I am trying to read FIX logs but I am struggling to do it without exposing the ParseMessage function.

There could be a better alternative that I am missing?

Expose store interface, introduce FileStore

2c_MsgSeqNumTooLow

AlreadyLoggedOn.def

Is there a way to run a client?

Currently hard-coded

Useful particularly for optional fields. Would allow for one line to set a field vs the current option, eg

order.SetStopPx(100)

//instead of...
px:=100
order.StopPx = &px

Currently session sends queued messages only after receiving incoming message or sessionEvent.
https://github.com/quickfixgo/quickfix/blob/master/session.go#L527
Is it possible to remove this timeout by firing something like "needSend" event or by changing toSend queue to channel logic?
