Subject [jira] [Commented] (DERBY-6350) Provide a rolling file implementation of derby.log
Date Wed, 23 Oct 2013 15:31:44 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13802949#comment-13802949
] 

Knut Anders Hatlen commented on DERBY-6350:
-------------------------------------------

The test cases could run in any order (there are techniques to force them to run in a specific
order, though). So it would be best if each test case cleaned up after itself completely.
The failing test run executed the test cases in the following order:

testMethod
testFile
testFileOverMethod
testFileOverField
testMethodOverField
testStyleRollingFile
testRollingFileStyleOverFile
testRollingFileStyleOverMethod
testRollingFileStyleOverField
testDefault
testWrongFile
testWrongMethod
testField
testWrongField
testWrongStyle
testFileOverMethodAndField
testDefaultRollingDefaultConfig
testDefaultRollingUserConfig

> 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.
