Tiago R. Espinha commented on DERBY-4757:
-----------------------------------------
I can. Maybe I should have put another comment there.
That change isn't actually necessary per se, the only thing is, by setting that
argument to true, in case the client can't convert the string using the current
CCSID manager, then it won't try to send it to the server. What the code inside
that function does is, it tries to convert the string and if we get an
exception, then we catch it and add it to the NetAgent. At a later point we can
choose to do something wise with that exception.
If the argument is set to false, it will effectively try to send the RDBNAM to
the server and it will still throw an exception but we don't catch it. We just
let it break as the client will still not be able to encode the string.
So this is more of just making sure that we don't even try to send an RDBNAM at
ACCSEC if we can't convert it. This is fine for newer clients, as they don't
expect RDBNAM at ACCSEC to be required and older clients will break, but then
again, if we can't send RDBNAM at ACCSEC to an older client, it means it has
UTF-8 characters and then it is supposed to break. If the RDBNAM does not have
UTF-8 characters, then the encoding process will go fine and old and new
clients will work perfectly.
