Description Cesar Eduardo Barros 2006-08-17 15:37:48 UTC
When the pre-expand size limit blocks expansion of a template, the parameters
are not shown; however, the output would be more readable if the template
parameters were visible (for instance, if {{unicode|asdf}} is not expanded, it
currently shows only {{unicode}}, which is not very helpful; if it showed
{{unicode|asdf}}, it would be more visible that the intention was to apply some
formatting to "asdf". The same applies to several other templates like
{{user|Example}}, {{tl|Template}}, {{nobr|text}}, etc).

> When the pre-expand size limit blocks expansion of a template

Any idea what that size is? (Reedy on IRC said "Presumably related to $wgMaxPPNodeCount and $wgMaxGeneratedPPNodeCount")

Any testcase where the problem could be reproduced, e.g. on test2.wikipedia.org?

Plus wondering how relevant this still nowadays, is in times of Lua.

«The pre-expand include size limit has been removed, since there's no efficient way to calculate such a figure, and it would now be meaningless for performance anyway. The "preprocessor node count" takes its place, with a generous default limit.»
