Tiago R. Espinha updated DERBY-728:
-----------------------------------
Attachment: DERBY-728_p2.diff
Here is the list of changes checked in by patch #2:
- Utf8CcsidManager.java is rolled in for the server - This CCSID manager is not
yet really used in practice. Instances are created but no real live code refers
to it yet. I'm still unsure about this implementation and this code might
change, but I needed to have a draft in place to proceed further.
- Both DDMWriter and DDMReader now have three CCSID manager attributes. These
two classes have one instance of each of the available managers (UTF-8 and
EBCDIC) and a reference to the current enabled one (already part of the
existing implementation).
These two classes also no longer receive a CCSID manager in their constructor.
Instead, they default to EBCDIC and whenever required we can setUtf8Ccsid() or
revert to EBCDIC by doing setEbcdicCcsid().
- The DRDAConnThread.java class has also lost its own ccsidManager and will be
using the one from its instance of DDMWriter. This class now initializes its
DRDAStrings within the initialize() method, as it is only then that we have a
DDMWriter available.
- Finally, the tests ProtocolTest and TestProto have also been changed to
accommodate the constructor changes in DDMWriter and DDMReader.

I will be running regressions tonight. Provided that all goes well and there
are no objections to this patch, it is ready for commit.
