These applications "log" the messages to the screen.  For example in 
.../examples/ordermatch/ordermatch.cpp you'll see code that looks like:

    FIX::FileStoreFactory storeFactory( settings );
    FIX::ScreenLogFactory logFactory( true, true, true );
    FIX::SocketAcceptor acceptor( application, storeFactory, settings, 
logFactory );


If you replace ScreenLogFactory(...) with FileLogFactory (settings) the 
logs will be written to a file rather than to the screen.

I wrote a document on creating custom messages and field in QuickFIX. It was supposed to be added to the QF documentation, but I don't see it there, so here's a link to the original message:

Hi I am getting QuickFIX up and running with BARX but need to add the Barclays  extension  StreamingQuoteDuration. This is not a QuickFIX message so i am wondering how to get it into the message. BARX assure me that they have clients who have done this so i am hoping someone can point me in the right direction.

You are probably using a ScreenLogFactory. Try changing that to a
FileLogFactory.

Re: [Quickfix-developers] StreamingQuoteDuration -- Barclays extension

[Mike P. <mic...@ya...>]

I'm assuming this is a field in a particular FIX message.
You can use the C++ Message.setField(int field, String value) method, with 'field' being the field/tag #.

Otherwise if this is a new FIX Message you can populate all of the fields (MsgType, BeginString, Sender/Target CompId/SubId, etc) manually vie the 'set' methods.
You can also add the Message definition to the xml files and I believe this will cause the objects to be generated.  I've never done this but it should be pretty easy to copy an existing message type.

Hope this helps.
Mike

[Quickfix-developers] FileLog not getting created

[lukas41 <mar...@gm...>]

Hi guys,

I'm new to quickfix. This forum had been very useful, and I would like to
thank everyone in advance.

I was able to run quickfix's example applications, such as ordermatch and
tradeclient. However, it doesn't seem like they are logging any outgoing
messages. I understand that I should be using FileLog for this purpose. I
see in the config file that I can specify a location for the log to go
to...as in
FileLogPath=store

However, nothing is getting logged there. The directory exists but it's
empty after I run these apps.

I looked around the source code, and I see that the FileLog gets generated
from a FileLogFactory. I put in some printout statements, and it seems like
FileLogFactory.create never gets called. Instead, screenlogfactory gets
created. What is the difference between screenlogfactory and filelogfactory?
Will I be able to log messages to a file using screenlog?

thanks

lukas

[Quickfix-developers] modifying filestore to log additional information

[fopguy <ma...@tr...>]

Hi everyone,

I am trying to modify filestore to log additional information. Whenever I
get a message, i want to log additional information.  I was able to
successfully modify the function FileStore::set(int msgseqnum, string msg)
so that additional information gets printed to the log file.

Unfortunately, this doesn't cut it. I actually need to pass this additional
information to the application layer, so that I can retrieve it inside
Application.cpp's fromApp function. Getting additional data in Filestore.cpp
is too late.

I'm not sure what the best way is to do this. I thought one way is to find
calls to FileStore.set (aka when the string that gets logged is generated),
modify that string, and then pass it up. But...I have 2 problems. 1) I don't
see where FileStore.set gets called.  and 2) I don't know if that is a
reasonable way to do this.

If someone could shed some knowledge on this, I would deeply appreciate it.

thanks

mark

Re: [Quickfix-developers] Peacefull coexistence of QuickFix and Twisted/wxPython

[Xavier P. <xav...@lu...>]

My mistake again, the initiator was trying to connect to a windows 
firewall and was getting a timout after 20sec.
So the poll() method seems to solve our problems, we will digg deeper 
that way from inside a python thread.

small other question, at the end of my loop, should i call 
acceptor.stop() ? (or clear() or del acceptor) to cleanup resources 
maintained by it ?

Thanks a lot,
Fugazy

Result 1:
Well I just made a small trial with poll() on a SocketInitiator and it 
seems to work OK, that is great.
But if i try it on a SocketAcceptor it seems that it will disconnect the 
clients every 20sec (whatever the heartbeat

Result 3:
My mistake, it doesn't hog the cpu, just not realease the 'python

[Quickfix-developers] How can I know QuickFix got the message? Body file?

[Alex M. <ale...@gm...>]

I moved the client to another machine, ran wireshark, and I can see the
TCP/IP fix message being sent.

So, its the server.  The server is also using quickfix. Is there a file
where the tcp/ip messages are logged. For some reason the toApp method isn't
being triggered but the Tcp/ip message is being sent.

thanks,
alex

[Quickfix-developers] if message is in body file, was it sent?

[Alex M. <ale...@gm...>]

I have a client that is sending a security defin request and this message is
in the body file.

However, the server isn't receiving it. This is all on one machine so I
can't see the traffic in wireshark.

So, if I see the message in teh body file, is it safe to say it was sent
over the socket to the server? is it safe to say to say that the server is
having the issue?

cheers,
alex

[Quickfix-developers] Peacefull coexistence of QuickFix and Twisted/wxPython

[Xavier P. <xav...@lu...>]

Hello List,

This is my first post to the list and i have a bunch of questions.
If this is not the correct list to post please tell me so i post it in 
quickfix-users

As an introduction, i'm new to QuickFix but not to Fix. We have been using
our own C++ fix engine that is not very easy to maintain and make evolutive
and we are willing to replace it with QuickFix. This should not give us to
much headaches in the C++ world but my problem right now is related to
the python wrappers.

We are using the QuickFix python wrappers and would like to use them in 
a wxPython
application. The trouble comes from the fact that both wxPython and 
QuickFix have
their own event loop.
I read some previous thread  about the peacefull coexistence of twisted 
and the
python wrappers, but didn't get the end conclusion (works on linux only?)
(Integrate socket connections into application-wide async socket loop)
(QuickFIX Python and Twisted)
(AHA! : QuickFIX Python and Twisted)

We managed to build the python wrappers under windows and we noticed the 
following :
we do get out of fix.SocketInitiator().start() but right after the next 
system call
after that the fix.SocketInitiator event loop take all the cpu.
So question 1:
    Is there a way to 'step' the fix engine, ie something in the path of
    -----
    acceptor     = fix.SocketInitiator( application, storeFactory, 
settings, logFactory )
    acceptor.start()
    while acceptor.isRunning():
        acceptor.step()
    acceptor.stop()

Question 2:
    is it possible to 'feed' the fix engine, ie i take care of all the 
socket work
    (open/accept/read/write) and feed the SocketInitiator/SocketAcceptor 
with the
    the one thing i can see that gives problem would be a 'callback' for 
it to
    write data to the socket.
    -----
    acceptor     = fix.SocketInitiator( application, storeFactory, 
settings, logFactory )
    acceptor.setWriteCallback(myWriteCallback)
    acceptor.start()
    -- manage my sockets and read data from it into socketData
    if acceptor.isRunning():
        acceptor.data(socketData)

Question 3:
    any other approach that will help me get the QuickFix event loop 
coexist peacefully
    with twisted or wxPython

BTW we have developper resources to devote to this pb, and i think it would
be more interesting to solve this pb in QuickFix, than to redevelop 
(once more) our own
python version of it (we only have 8 messages to implement and doing it from
what we have in pure python should be in the 10-15 days work)

plateform :
Python2.4 win32
QuickFix 1.12.4 (stock)

Any pointer(s) would be greatly appreciated.
Thanks,
Fugazy

Hi John,<BR><BR>I guess that your QFRouter have hung because the ThreadedSocketAcceptor is implemented using a blocking socket. The connection is not broken, but the modal dialog in your client is preventing the tcp ack. QFRouter will keep frozen until QFClient sends some kind of receiving confirmation, which in your case will happen only when someone closes the modal dialog.<BR><BR>If you have QF 1.12.4 you can use the SocketAcceptor to try to solve this problem.<BR><BR>Because of performance issues, I preferred to make my own non-blocking implementation which I have already submitted.<BR><BR>Djalma<BR><BR>

<DIV>
<DIV><SPAN><FONT face=Arial size=2>I had an interesting scenario happen here and was wondering if somebody could sanity check whether what I think happened actually happened, and if so what I might be able to do to handle this scenario if it pops up again.&nbsp; Here's the details:</FONT></SPAN></DIV>
<DIV><SPAN></SPAN>&nbsp;</DIV>
<DIV><SPAN><FONT face=Arial size=2>I have an application (QFrouter) which goes out and connects to 6 source systems (brokers/exchanges) using the threadedSocketInitiator.&nbsp; It also allows connections from 20+ client apps (QFclient) using the threadedSocketAcceptor.&nbsp; When a message comes in from an exchange/broker, I handle the callback and check certain fields in the message and determine which of my client apps should get a copy.&nbsp; I then send a copy of this incoming message to each of my clients by "rewiring" the sendercompid and the targetcompid and fan copies out to each client using the SendToTarget method.</FONT></SPAN></DIV>
<DIV><SPAN></SPAN>&nbsp;</DIV>
<DIV><SPAN><FONT face=Arial size=2>So far, all of this has worked fine (up until today).&nbsp; [The above process may not be the best way to do this, and I'd love to hear from somebody if this is a dumb way to do this, but that isn't my question right now.]</FONT></SPAN></DIV>
<DIV><SPAN></SPAN>&nbsp;</DIV>
<DIV><SPAN><FONT face=Arial size=2>Today a message came in from an exchange connection (ARCA1) and my code proceeded to send copies to each of my client apps.&nbsp; It got through the first 3 client apps and then tried to send to the 4th client app on my list of clients.&nbsp; At this point the client app in question ran out of disk space on the client workstation, resulting in a modal pop-up dialog box appearing on the client workstations saying "out of disk space".&nbsp; (One important factoid is that I didn't know the client workstation was stuck with a modal dialog box being displayed at this point.&nbsp; Might be relevant later in the story.)</FONT></SPAN></DIV>
<DIV><SPAN></SPAN>&nbsp;</DIV>
<DIV><SPAN><FONT face=Arial size=2>Once this happened, the thread in my QFrouter seems to have hung.&nbsp; The connection to ARCA1 eventually dropped when I didn't respond to a heartbeat, but my QFrouter never recovered, and eventually I had to kill the process and bounce QFrouter.&nbsp; Once&nbsp;I bounced QFrouter, I reconnected to ARCA1 and messages started flowing.&nbsp; As soon as I received a message that needed to be copied to client #4, my QFrouter hung again.&nbsp; At this point we discovered that client #4 had a modal dialog freezing the app.&nbsp; As soon as we deleted some files (freeing up sdisk space)&nbsp;from client workstation #4 and pressed ok on the modal dialog, messages started flowing to the client app and my QFrouter got "unstuck".</FONT></SPAN></DIV>
<DIV><SPAN></SPAN>&nbsp;</DIV>
<DIV><SPAN><FONT face=Arial size=2>In digging into my logs, it appears that the modal dialog was created by a generic exception handler in my client app (QFclient), and was triggered within the onMessage callback when either the QF engine or my app (unclear which)&nbsp;attempted to log the incoming message.&nbsp; With hindsight, I will of course handle this scenario in QFclient in a more graceful manner.</FONT></SPAN></DIV>
<DIV><SPAN></SPAN>&nbsp;</DIV>
<DIV><SPAN><FONT face=Arial size=2>But what I'm really curious about is whether QFrouter should have handled the fact that client #4 wasn't responding.&nbsp; I would have thought that in this scenario the QF engine in QFrouter should have recognized that client #4 wasn't responding and dropped that conenction wtihin the threadedSocketAcceptor and moved on -- or at least thrown an exception of some sort.&nbsp; But it didn't - it simply seems to have frozen on that thread.&nbsp; Meanwhile, messages continued to be processed coming in from the other exchanges/brokers on the threadedSocketInitiator and passing those messages on to clients.</FONT></SPAN></DIV>
<DIV><SPAN></SPAN>&nbsp;</DIV>
<DIV><SPAN><FONT face=Arial size=2>Am I correct in thinking that my QFrouter should have handled this scenario more gracefully?&nbsp; If so, should I have coded differently to expect this scenario?&nbsp; Should an exception of some sort been thrown by the QF engine?</FONT></SPAN></DIV>
<DIV><SPAN></SPAN>&nbsp;</DIV>
<DIV><SPAN><FONT face=Arial size=2>For reference, both QFrouter and QFclient are VB .NET 2005 apps, and both have the generic binary .dll that ships with QF, runtime version 2.0.50727, version 1.0.2447.42056.&nbsp; Both apps have been running happily for months, but this is the first time we had a disk space error.</FONT></SPAN></DIV>
<DIV><SPAN></SPAN>&nbsp;</DIV>
<DIV><SPAN><FONT face=Arial size=2>If anybody has any thoughts on this I'd greatly appreciate it.</FONT></SPAN></DIV>

<DIV><SPAN class=406321315-17042008><FONT face=Arial size=2>Once this happened, the thread in my QFrouter seems to have hung.&nbsp; The connection to ARCA1 eventually dropped when I didn't respond to a heartbeat, but my QFrouter never recovered, and eventually I had to kill the process and bounce QFrouter.&nbsp; Once&nbsp;I bounced QFrouter, I reconnected to ARCA1 and messages started flowing.&nbsp; As soon as I received a message that needed to be copied to client #4, my QFrouter hung again.&nbsp; At this point we discovered that client #4 had a modal dialog freezing the app.&nbsp; As soon as we deleted some files (freeing up sdisk space)&nbsp;from client workstation #4 and pressed ok on the modal dialog, messages started flowing to the client app and my QFrouter got "unstuck".</FONT></SPAN></DIV>

<DIV><SPAN class=406321315-17042008><FONT face=Arial size=2>In digging into my logs, it appears that the modal dialog was created by a generic exception handler in my client app (QFclient), and was triggered within the onMessage callback when either the QF engine or my app (unclear which)&nbsp;attempted to log the incoming message.&nbsp; With hindsight, I will of course handle this scenario in QFclient in a more graceful manner.</FONT></SPAN></DIV>

<DIV><SPAN class=406321315-17042008><FONT face=Arial size=2>But what I'm really curious about is whether QFrouter should have handled the fact that client #4 wasn't responding.&nbsp; I would have thought that in this scenario the QF engine in QFrouter should have recognized that client #4 wasn't responding and dropped that conenction wtihin the threadedSocketAcceptor and moved on -- or at least thrown an exception of some sort.&nbsp; But it didn't - it simply seems to have frozen on that thread.&nbsp; Meanwhile, messages continued to be processed coming in from the other exchanges/brokers on the threadedSocketInitiator and passing those messages on to clients.</FONT></SPAN></DIV>

<DIV><SPAN class=406321315-17042008><FONT face=Arial size=2>Am I correct in thinking that my QFrouter should have handled this scenario more gracefully?&nbsp; If so, should I have coded differently to expect this scenario?&nbsp; Should an exception of some sort been thrown by the QF engine?</FONT></SPAN></DIV>
<DIV><SPAN class=406321315-17042008></SPAN>&nbsp;</DIV>
<DIV><SPAN class=406321315-17042008><FONT face=Arial size=2>For reference, both QFrouter and QFclient are VB .NET 2005 apps, and both have the generic binary .dll that ships with QF, runtime version 2.0.50727, version 1.0.2447.42056.&nbsp; Both apps have been running happily for months, but this is the first time we had a disk space error.</FONT></SPAN></DIV>

Re: [Quickfix-developers] stopping a single session

[<or...@qu...>]

<html><body><div>These both look pretty reasonable to me, some additional tests might be required to verify them.&nbsp; As for not listening on the socket, this is much more tricky.&nbsp; There is not a one to one relationship between a session and the listening socket.&nbsp; It is entirely possible one acceptor socket is servicing a few or even hundreds of waiting sessions.&nbsp; So I don't know if it is really feasible to tell a session to disable and at the same time shut the socket down.&nbsp; The best I can think is if the acceptor can determine that all waiting session are disabled, then we can stop listening on the socket.&nbsp; But this is pretty much equivalent to stopping the acceptor.<BR></div>

Re: [Quickfix-developers] TradeClient on C++ OpenSource N0 MS VC++

[Mike G. <mg...@co...>]

You could install a cygwin environment <http://www.cygwin.com> and build 
quickfix with GCC.
