ASF subversion and git services commented on DERBY-4805:
--------------------------------------------------------

Commit 1566771 from [~mamtas] in branch 'code/trunk'
[ https://svn.apache.org/r1566771 ]

DERBY-4805(Increase the length of the RDBNAM field in the DRDA implementation)

This commit makes the in-memory URLs in the test use absolute path names. That way, they won't
be made longer after java.io.File.getCanonicalPath() has been called on them.

Without this change, the test was failing on Solaris but passing on Windows and Linux.

> Currently, whenever the client driver is used, there is a limit of 255 bytes for the
database name. This is defined by the DRDA spec and there has been a discussion on the list
[1]/[2] as to whether this limit should be raised due to the introduction of the new ACR that
allows for UTF-8 characters.
> UTF-8 characters can take up to four bytes and this reduces the limit in characters dramatically.
> This should be an easy change as there is a codepoint that defines this limit.
> [1] did not work but [2] did
