[Firebird-odbc-devel] ODBC driver changes

[Paul R. <pr...@ib...>]

Well, I've finally managed to collate all the contributions that have 
been made to the driver recently.

The changes have been committed to the source tree. Now, we need to test 
them. The only guarantee at the moment is that the code compiles.

I have deliberately chosen to get the changes committed before testing 
them properly because there are several people working on the code at 
the moment and we are in danger of tripping over ourselves. This will 
give everyone a chance to re-sync.

All the changes have been clearly documented. Where code has been 
removed I have commented it out and marked it thus:

   //Orig.

After the removed code I have inserted the suggested changes, starting 
with a brief comment to attribute the change to its owner. Each changed 
file has an amended header summarizing the changes and there is now a 
change log, which you can see below.

Hopefully it will be clear enough to understand what has changed and 
why. For now, we need developers with access to MSVC to actually test 
the changes. There is not much point in testing without the ability to 
trace through the debug code at this stage.

I know there are some more changes in the pipeline. When they are in I 
will look to getting a snapshot beta release out for more widespread 
testing.

Thanks to everyone who has contributed.

Finally, I must just add that I was having difficulties with my mail 
reader recently. This meant that I could'nt easily post to this list and 
had to do everything privately. I've got a new mail reader that works 
with my sourceforge id now, so hopefully we can keep everything out in 
the open and all can benefit from discussions about changes.
