[Mono-dev] Submitting patch?

Well, i added the test about a week ago.  The test works for me, it 
demonstrates failure (a null reference exception) in the case where the 
patch i wrote isn't applied, and it passes when the patch is applied.  I 
realize i'm the only one to report this problem, so it's low priority, 
but i wanted to mention to whomever is responsible that if they have any 
questions, i'm here for now (that is: I still subscribe to the list).

To me, again, the patch is straightforward and obviously needed -- 
There's a retry point and the first thing it checks in retry is if 
'result==null' (to enter the while loop) and that retry point is only 
hit under one circumstance, and in that circumstance, result is never 
null, so as a result, if the intention was for it to be anything other 
than null the retry point would be elsewhere.  Therefore, it should be 
blatantly obvious to anyone reading the code, that setting result to 
null so the check at the retry point can enter the while loop at the 
retry point, is the only thing that is needed to make it work.

To debug this originally, i inserted trace points to confirm what was 
going on.  It was stuck endlessly jumping to the retry point and not 
doing anything other than jumping directly to the retry point again and 
again until it got tired of that and failed, and every time after the 
first, it never enterred the while loop at the retry point, begging the 
question, if null wasn't intended (which it was), why not move the retry 
point elsewhere below the while loop.

If someone thinks this breaks something else, please let me know.

It's on github - https://github.com/mono/mono/pull/283 ...  I understand 
if my nunit test is the reason it is rejected, it was the most 
quick/straightforward way to do the tests, it was extracted from 
sqlconnection.open() extracting only the code that was required to set 
up the TdsConnectionPool GetConnection() call it uses.
