[xwiki-devs] Page Complexity limiter

Devs, In MediaWiki there are preprocessor limits <https://en.wikipedia.org/wiki/Wikipedia:Template_limits> that track how complex a page is so that rendering can gracefully bail out if any of these limits are broken to keep the server stable. MediaWiki will include this information in a comment in the rendered page like: &lt;!-- NewPP limit report Parsed by mw1270 Cached time: 20170223033729 Cache expiry: 2592000 Dynamic content: false CPU time usage: 0.124 seconds Real time usage: 0.170 seconds Preprocessor visited node count: 468/1000000 Preprocessor generated node count: 0/1500000 Post‐expand include size: 50512/2097152 bytes Template argument size: 37/2097152 bytes Highest expansion depth: 7/40 Expensive parser function count: 0/500 Lua time usage: 0.039/10.000 seconds Lua memory usage: 1.66 MB/50 MB --&gt; We have cases where our users will want to include pages as templates into other pages and these can get pretty deeply nested as well as contain some complex content that is expensive and/or takes a long time to render. We want to make sure that a user cannot bring our servers down accidentally or intentionally due to using too many expensive/long running inclusions on their pages. Testing this on our instance of XWiki is showing that XWiki will run until a) the page is finally able to render which could be minutes in some cases or b) the server runs out of memory and falls over. I have been looking but have been unable to find if XWiki has this sort of feature to turn on and configure. I was also unable to find it in the XWiki Jira or in this forum so I wanted to ask the Devs directly. Does this sort of limiting exist on XWiki? And if so, how can I turn it on?
