[jira] [Commented] (DERBY-5543) include debug info in derby builds
uploaded to maven
[ https://issues.apache.org/jira/browse/DERBY-5543?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13170580#comment-13170580 ]
Dag H. Wanvik commented on DERBY-5543:
--------------------------------------
I don't believe we want to make this the default download, since the "sane" version which has line numbers complied in also has other instrumentation enabled and is significantly slower. We could possibly install a debug version as well (with another name).
You can also download the debug jar files from the Apache site, of course, @ http://db.apache.org/derby/derby_downloads.html

> Key: DERBY-5543
> URL: https://issues.apache.org/jira/browse/DERBY-5543
> Project: Derby
> Issue Type: Improvement
> Components: Build tools
> Affects Versions: 10.8.2.2
> Reporter: Sean Bridges
> Priority: Minor
>
> Looking at a strack trace from derby retrieved through maven, I see that derby is compiled without debug information, this means line numbers are not available in stack traces,
> Caused by: java.lang.NullPointerException
> at org.apache.derby.impl.store.raw.data.BaseDataFileFactory.openContainer(Unknown Source)
> at org.apache.derby.impl.store.raw.data.BaseDataFileFactory.openDroppedContainer(Unknown Source)
> at org.apache.derby.impl.store.raw.xact.Xact.openDroppedContainer(Unknown Source)
> at org.apache.derby.impl.store.raw.data.PageBasicOperation.findpage(Unknown Source)
> at org.apache.derby.impl.store.raw.data.PageBasicOperation.needsRedo(Unknown Source)
> and it is harder to debug code by setting breakpoints within derby. Derby deployed to maven should have debug information included.
> I'm not sure how this is controlled, but looking at pom.xml I see,
> <!-- Specifies whether to package the sane (debug) or insane jar.
> Valid values: sane|insane
> -->
> <sanity>insane</sanity>
> The default should be sane.
