What the way you suggest now to check if a section is exists (like the parser function "#exists:")?
Untill now we used on the Hebrew Wikisource a template for this purpose, that contain the idea of
{{#if:{{#lst:articleX|chapter1}}|{{#lst:articleX|chapter1}}|}}but now we have 53,000 pages and 16,000 categories on "category:Pages transcluding nonexistent sections". Is there any advice or a build-in solution, how to check it without the problem?
Hi @Shalomori123. This does not sound like something is wrong in the code base (a so-called "software bug"), but instead like a support request (how to change settings, questions how to do something, etc.).
As Wikimedia Phabricator is for bug reports, enhancement requests, and planning work, please check https://www.mediawiki.org/wiki/Communication and/or use https://meta.wikimedia.org/wiki/Tech for questions about Wikimedia wikis. Thanks for your understanding!
I'm reopening this as it seems like a valid feature request to me - there should be a way to check whether a section exists without populating a tracking category if it doesn't, and there isn't (other than hacks like this).
@Aklapper, you are right that it sounds like a how-to question, but it's only sounds (maybe I should rephrase it), since the code "improvement" created problems that didn't exist (T336628 is another example). When you add a feature you have to check that it doesn't break anything else, and that's why I attract your attention to it.
@Shalomori123: In that case, in the future, please use the feature request form (linked from the top of the task creation page) to create feature requests, and fill in the sections in the template. Thanks!
If you think that it's a bug report, then please change the subtype to bug report. In any case, please use templates to avoid misunderstandings - thanks!
