[Quickfix-developers] Quickfix42 getHeader() problem for .NET - PROBLEM SOLVED

From: Christodoulou, Chris D (london) <chris_d_christodoulou@ml...> - 2003-09-30 15:34

Hi

Just to let you know, I have solved the problem with the getHeader(). It was
a bug in the quickfix source code.

The derived class Message was actually creating a quickfix header as the
compiler had 2 choices (base and derived), so the compiler picked the one
most local to it, that is

	m_header = new Header(this); was really creating a quickfix header
instead of quickfix42.

Therefore 
	m_header = new QuickFix42::Header(this); will sort problem.

I had to go through all the code to make the necessary changes.

Thanks
Chris

[Quickfix-developers] isSameSession method

From: Jo Janssens <jo@tr...> - 2003-09-30 15:33

Attachments: Message as HTML

I have noticed that in testing, if I start a session at say, 12:00:00
noon (my time) one day, and restart the program the next day at say,
10:00:00 am, quickfix does not restart the session - it thinks I am
still in the same session even though it is a new day. Is this intended
behavior, or is this a bug?
 
Upon reading the code, I understand why this occurs - the isSameSession
method tests if it has been 24 hours since the last session start time
and also tests whether the session start time and the current time fall
within the trading day, but it does not use the date in this latter
check, so it cannot tell that my previous session was actually started
late in the previous trading day.
 
Oren, do you think this should be changed? I will write my own version
of this function for my own use, let me know if you want it.
 
Thanks,
Jo Janssens

[Quickfix-developers] MySQL Integration

From: Jon Dahl <jdahl@li...> - 2003-09-30 13:50

I was wondering if anyone out there has implemented the MySQL interface
for the "Store" instead of writing to log files and if so has the =
performance
been better than reading/writing to disc.

I admit I don't have a whole lot of experience with MySQL but I have =
been thinking
about implementing it as our "Store".

Thanks,

JD

Re: [RE: [Quickfix-developers] JVM Crashing, calling Pure Virtual Function]

From: Arif Aziz <azizarif@us...> - 2003-09-30 11:23

Hi Oren,
I have just found out a small error, which may be the cause of this probl=
em..
in
org_quickfix_SocketInitiator.cpp file
following method is defined:

JNIEXPORT void JNICALL Java_org_quickfix_SocketInitiator_doBlokcingStart
( JNIEnv *pEnv, jobject obj )


and there is clearly a spelling mistake in "doBlokcingStart"

which should be "doBlockingStart"

due to which the mmethod "doBlockingStart" could not be found in quickfix=

dll.

I am changing my source..lets hope for the best.

Re: [RE: [Quickfix-developers] JVM Crashing, calling Pure Virtual Function]

From: Arif Aziz <azizarif@us...> - 2003-09-30 12:29

Hi Oren,
To fix this problem I changed org.quickfix.SocketInitiator.java as follow=
s:

I added a new method:
    public void blokcingStart() throws RuntimeError, ConfigError {
        doBlokcingStart();
    }

and a new native method:
private native void doBlokcingStart() throws RuntimeError, ConfigError;


and recompiled the whole java wrapper source to generate new quickfix.jar=
=2E
And In my application I called initiator.blokcingStart()

I ran my program and now it is not able to find the "doBlokcingStart"
method.:

java.lang.UnsatisfiedLinkError: doBlokcingStart
	at org.quickfix.SocketInitiator.doBlokcingStart(Native Method)
	at org.quickfix.SocketInitiator.blokcingStart(SocketInitiator.java:102)

I inspected the quickfix_jni.dll and it did contain a method name:
by the name of "doBlokcingStart"

Now I really dont know what to do.
Arif
