  • xwiki.cfg
  • xwiki.properties

Issues specific to XWiki 15.10.16

New query validation in the REST Query HQL endpoint and for the short form queries in the script API

The validation of HQL queries given to the REST Query HQL endpoint and to the Query script API has been modified to be more consistent. This validation is a lot stricter than it used to be for those use cases, which may cause some perfectly valid (but complex enough to not be understood by the validator) queries to be forbidden if the current user (or the author of the script depencing on the user case) does not have programming right.

Don't hesitate to report an issue on https://jira.xwiki.org/browse/XWIKI if this happens. A workaround in the form of a configuration to explicitly indicate allowed query statements has also been introduced to workaround potential false positives. See Query Module for more details about this new configuration.

The following APIs were modified since XWiki 15.10.15:
