Because the %union can only contain POD types, complex objects must be new'd and passed around by pointer. If a syntax error occurs, the yacc parser just stops running, and references to all of those created objects are lost.
The only solution I've come up with is that all new'd object inherit a particular base class, be added to a container when allocated, and if there is an error everything in that container can be deleted.
Does anyone know of any better yacc tricks to solve this problem?

We need to support WCF as well as non-WCF service consumers/clients, including SOAP 1.1 and SOAP 1.2 clients.
FYI: using FaultExceptions with wsHttpBinding results in SOAP 1.2 semantics whereas using FaultExceptions with basicHttpBinding results in SOAP 1.1 semantics.
I am using the following code to throw a FaultException<FaultDetails>:
throw new FaultException<FaultDetails>(
new FaultDetails("Throwing FaultException<FaultDetails>."),
new FaultReason("Testing fault exceptions."),
FaultCode.CreateSenderFaultCode(new FaultCode("MySubFaultCode"))
);
The FaultDetails class is just a simple test class that contains a string "Message" property as you can see below.
When using wsHttpBinding the response is:
<?xml version="1.0" encoding="utf-16"?>
<Fault xmlns="http://www.w3.org/2003/05/soap-envelope">
<Code>
<Value>Sender</Value>
<Subcode>
<Value>MySubFaultCode</Value>

<Message>Throwing FaultException<FaultDetails>.</Message>
</FaultDetails>
</Detail>
</Fault>
This looks right according to the SOAP 1.2 specs. The main/root “Code” is “Sender”, which has a “Subcode” of “MySubFaultCode”. If the service consumer/client is using WCF the FaultException on the client side also mimics the same structure, with the faultException.Code.Name being “Sender” and faultException.Code.SubCode.Name being “MySubFaultCode”.
When using basicHttpBinding the response is:
<?xml version="1.0" encoding="utf-16"?>
<s:Fault xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<faultcode>s:MySubFaultCode</faultcode>

<Message>Throwing FaultException<FaultDetails>.</Message>
</FaultDetails>
</detail>
</s:Fault>
This does not look right. Looking at the SOAP 1.1 specs, I was expecting to see the “faultcode” to have a value of “s:Client.MySubFaultCode” when I use FaultCode.CreateSenderFaultCode(new FaultCode("MySubFaultCode")). Also a WCF client gets an incorrect structure. The faultException.Code.Name is “MySubFaultCode” instead of being “Sender”, and the faultException.Code.SubCode is null instead of faultException.Code.SubCode.Name being “MySubFaultCode”. Also, the faultException.Code.IsSenderFault is false.
Similar problem when using FaultCode.CreateReceiverFaultCode(new FaultCode("MySubFaultCode")):
- works as expected for SOAP 1.2
- generates “s:MySubFaultCode” instead of “s:Server.MySubFaultCode” and the faultException.Code.IsReceiverFault is false for SOAP 1.1

My boss is convinced that compiling our (***my***) webapp into a binary executable is a brilliant idea. (Then again, he likes nice, small simple things with blinky lights that he can understand.) He instinctively sees no issues with this, while I only see an endless series of problems and degradations. Once I start talking to him about the complexity of our platform, and more in depth specifics of byte code, JVMs, libraries, diferences between operating systems, processor architectures, etc...well...his eyes glaze over, he smiles and he has made it clear he thinks I'm being childishly resistive.
So, I've done my obligatory 20 minutes of googling, and now I am here.
A bit of background on my application:
**What it is made from:**
- Java 6
- AspectJ 1.6
- Tomcat 6
- Hibernate 3
- Spring 2
- another two dozen supporting jar files
**What it does**
- A streaming media CMS
- Performance sensitive
- Deployed on Linux, Solaris, Windows (and developed on a Mac)
As you can probably gather, I'm highly skeptical of this *"compiling Java to native code"* thing. It sound like where Mono (VB on Linux) was back in 2000. But am I being overly pessimistic? Is it viable? Should I actually spend the time (days if not weeks) to try this out?
There is one other similar thread ([Java Compiler Options to produce .exe files][1]) but it is a bit too simple, the links dated, and not really geared towards a server-side question.
Your informed opinions will be highly cherished, my dear SOpedians! TIA!

So, as with any Java errors, I go down the stack trace to find where this is being generated from. The issue I am having is that, none of the classes I have made show up in the trace... this leads me to beleive (and I might be wrong) that this isn't generated from my code - even tho it makes no sense being that my code almost HAS to be the source of this error.
Any input on this would be greatly appreciated.

This results in the control instance's destructor not being called.
The control is written in C++, uses ATL and it's compiled using Visual Studio 2005. The control instance's destructor is always called when the user browses away from the page the control is embedded in - the problem only occurs when the browser is closed.
When I run IE under a debugger, I don't see anything unusual - the debugger doesn't catch any exceptions, access violations or assertion failures, but the problem is still there - I can set a breakpoint in the control's destructor and it's never hit when I close the broswer.
In addition, when I load a simple HTML page that embeds multiple instances of the control I don't see the problem. The problem only appears to happen when the control is instantiated from our web application, which inserts <object> tags dynamically into the web page - of course, not knowing what causes this problem, I don't know whether this bit of information is relevant or not, but it does seem to indicate that this might be an IE problem, since it's data dependent.
When I run the simple test case under the debugger, I can set a breakpoint in the control's destructor and it's hit every time. I believe this rules out a problem with the control itself (say, an error that would prevent the destructor from ever being called, like an interface leak.)

I still remember the serialization issues I had with DateTime and the testing effort it took for servers in different time zones.
My questions is this: Is there a similar best practices document for some of the new technologies like WCF and SQL server 2008 especially with the addition of new datetime types for storing time zone aware info.
This is the environment:
1) SQL server 2008 on Pacific Time.
2) Web Services layer on a different time zone.
3) Clients could be using .Net 2.0 or .Net 3.5 on different time zones. If it makes it easy, we can force everyone to upgrade to .Net 3.5.

It also seemed to provide realistic guidance for an organisation to progress up the levels improving their processes.
But while it seemed to provide a good model and realistic guidance for improvement, I never really witnessed an adherence to CMM having a significant positive impact on any organisation I have worked for, or with.

So I'm wondering, has anyone seen a real, tangible benefit from adherence to process improvement according to CMM?

However, I haven't been able to find a good .NET implementation that allows me to do this within IIS (our application is written in ASP.NET 2.0).
The solutions I found (or could think of, for that matter) require leaving a running thread per user - so that it could return a response to him once he gets a message. This doesn't scale at all, of course.
So my question is - do you know of an ASP.NET implementation for Comet that works in a different way? Is that even possible with IIS?

What solutions are out there (free/OSS preferred) that help me get this repetitive tasks cranking? | php | reporting | null | null | null | null | open | report generation on php?

For Example, if the run directory looks like this:
.
..
1.2.1
1.2.2
1.3.0
run.sh
current_version
And current_version contains:
1.2.2
I want run.sh to descend into 1.2.2 and run the program foo.
The current solution is this:
!#/bin/sh
version = `cat current_version`
cd $version
./foo
It works but is not very robust. It does not check for file existence, cannot cope with multiple lines, leading spaces, commented lines, blank files, etc.
What is the most survivable way to do this with either a shell or perl script?
