----------------------------------------
Hi Brett, thanks for working on this useful feature. I am planning on looking
at the patch soon. In the mean time, for the junit tests, you may want to look
at jira DERBY-5996(Create readme files (cautioning users against modifying
database files) at database hard upgrade time). In this jira, I look at the
existence of the readme files. You may need something like that to make sure
rolling derby.log files get created with the appropriate names. I am pretty
sure I added tests to upgrade suite as well to check for the existence of
readme files at hard upgrade. Is it correct that we will not create rolling log
files on a soft upgrade even if user adds these properties to derby properties
file? Thanks

> By default, derby.log grows without bounds if the derby.infolog.append
> property is set to "true". Setting this to "true" helps in a hands off
> production environment to ensure that if Derby restarts, the derby.log which
> might contain important information is not lost. On the other hand, when set
> the "true" the derby.log grows without bounds. This is problematic in a long
> running system.
> What is really needed is the ability to have a rolling derby.log file support
> where the maximum file size and maximum number of files can be specified.
> Derby has the ability to configure the location of the log file (ie.
> derby.stream.error.file) and also two methods of redirecting the error stream
> (.ie derby.stream.error.method and derby.stream.error.field). There is no
> standard implementation that supports a rolling derby.log however.
> This facility should be part of the core Derby system so that it works in
> both embedded and network server models.
