Hi devs,

I am currently working on XWIKI-8718 ( http://jira.xwiki.org/browse/XWIKI-8718) to improve the reporting of failed or missing migration directly in the error reported by the browser. To do so, I keep a cache of the exceptions generated by migrations, and reattach them to all access failure to a given database. This will really help the end user, since it is no more necessary to dig the logs to notice a duplicate key issue in a migration.

However, during a simple initial request to XWiki, a lot of access is done to the database, and many of them are not fatal (especially in a farm with a valid main wiki), but reports warnings or errors to stdout. This produce between 5K (main wiki had failed) to 22K lines (a subwiki has failed).

Most of them are caused while getting a value in preference of user, space or wiki. And since these are linked together, in a fallback manner, getting a user preferences cause three error reports and space two.

Currently these errors are logged at WARN level. Since all these are not fatal, and provide correct fallbacks for the current situation, I would like to reduce that log level to DEBUG. Doing so will significantly simplify the logs (around 2K lines), and avoid really repetitive reports, since each access to a single value of the preferences are reported individually.

Here is my +1 to reduce to DEBUG, the log level of: XWiki#getUserPreference(String prefname, XWikiContext context) XWiki#getSpacePreference(String preference, String space, String defaultValue, XWikiContext context) XWiki#getXWikiPreference(String prefname, String fallback_param, String default_value, XWikiContext context)

WDYT ?
