You had very well much know what Microsoft does and care very much about 
what they do.  The goal of this project, as it has been since the mid 
1990s is to fully emulate, bug and all, the Microsoft Windows32 and 
Windows64 (since 64 bit versions of Windows arrived) APIs.  Thus we have 
test cases that demonstrate what the actions are of the API/ABI.  That 
is what I've been working on with several richedit functions that I need 
to have for programs that I personally use.  I'm 'eating my own dog 
food' to speak.

I looked at the testcase.  He will need to 'beef up' the testcase to 
demonstrate what functions that particular test case does.  If it does 
return "not implemented" then it has to be demonstrated.   I tried to 
point this out as did Nicolay and Dmitry.  Otherwise, this patch will be 
rejected by AJ as an attempt to silence the fixme, which he detests greatly.

No.  we have stated that you have no authoritative source that you are 
correct.  State this and we all will be satisfied that the patch you 
propose is correct.  Right now, it appears as if the patch is just a 
'silence the fixme' attempt.  This is why your original set of patches 
was beat up.  We want to know, and so do our users, that implementation 
is not complete for functions.  If this is breaking a program you are 
using, you are welcome to fully implement the function.  That is what we 
are all here for.  Fixmes are not the way to go, but if a stub makes 
things work that is the first step of many.  There are many fixmes in 
Wine code and I'm working on three of them in the richedit dll that 
directly affect the ability for me to properly use programs.  I've built 
a test case for one of them, that was rejected by AJ.  I'm working on a 
second test case and then will build out code from that position.  This 
is how the project moves ahead.

We really are not out to get you.  I work, daily, as a software QA 
analyst.  I reject perfectly good looking software because it behaves 
strangely and does not react properly to improper inputs.  It is not 
easy being on that end of the process, however I also understand that 
writing proper code and having good/superb test cases makes all the 

The bottom line is that there is no test case that validates your 
change.  Create one.  If your change is wrong, you then have the 
knowledge to state "I withdraw".  I've done that, several times.  If it 
is right, then add the test case, first, then the new code and state 
this is based on your test case and when you ran it in the change log.  
Makes us all happy and it furthers the state of Wine.

Also, strongly defending your patches without authoritative information 
marks you as being arrogant.  After a while, your patches will be 
ignored.  That is not a good place to be in this project.
