Hoss Man commented on SOLR-1145:
--------------------------------
Mark: all your points are valid.
Do me one favor: instead of this...
{code}
<infoStreamFile>/path/to/infostream/file</infoStreamFile>
{code}
Make the config sequence something like...
{code}
<infoStream file="/path/to/infostream/file" />
{code}
...so we don't paint ourselves into a corner, and we can easily add logging
based infostream option later if we want. (using a new 'logger="..."' xml
attribute instead of 'file')
On a related note, Having an explicit true/false (ie: on/off) option seems like
a good idea so it's easy to control with a system property at startup....
{code}
<infoStream file="/path/to/infostream/file">${solr.infostream:true}</infostream>
{code}
> Patch to set IndexWriter.defaultInfoStream from solr.xml

> Lucene IndexWriters use an infoStream to log detailed info about indexing
> operations for debugging purpose. This patch is an extremely simple way to
> allow logging this info to a file from within Solr: After applying the patch,
> set the new "defaultInfoStreamFilePath" attribute of the solr element in
> solr.xml to the path of the file where you'd like to save the logging
> information.
> Note that, in a multi-core setup, all cores will end up logging to the same
> infoStream log file. This may not be desired. (But it does justify putting
> the setting in solr.xml rather than solrconfig.xml.)
