Re: [Wikidata-l] Using Special:Unconnected Pages? Please read.
Thanks so much for the feedback. That was useful. We'll rework the page to make it not time-out as it currently does on larger wikis. The way we'll go for to achieve this is by sorting the pages by page-id rather than page-title. That should also make it relatively easy to find the newest or oldest pages depending on which you're working on. We'll also provide a filter for the namespace but that might come a bit later.

...and one additional thing; use of this page is client side, not server side. That imply that the communities at the client side should be asked, not the community at the server side. Which means that this list is the wrong forum. John On Fri, May 15, 2015 at 2:58 PM, John Erling Blad jeb...@gmail.com wrote: That would effectively make the output quasirandom, make paging confusing, and look up of specific pages and following pages impossible. In all I think this makes the page useless for anybody except those projects that has managed to clean up the remaining unconnected pages, and those that has less than 5000 (I think that is the limit) pages in the list. I would rather suggest that an optional category should be added, and that it should be mandatory if the namespace page count indicates that the number of pages goes above some limit. I think the start was implemented as a prefix search originally, but I wonder if that is still the case. It could be wise to check it out. It could be an idea to use a default prefix search if none is added. If neither a prefix pattern or a prefix search are used, then a page-id sorted first N hits can be returned. It should also be possible to switch between oldest first and newest first. The seemingly caching behavior is probably the update which arrives late, but it could be an indication of other issues. The same bug was fixed several years ago, and disappeared, so it can be a new bug. It is interesting that there are now real needs for caching and an API, the page itself wasn't much appreciated and deemed unnecessary when it was created. This it has in common with a lot of the maintenance pages, the editors use them even if they are really crappy. Other special pages are using old, often several days old, reports as their source. When it comes to maintenance reports they should be up to date and actionable, not outdated and questionable. /rant John On Fri, May 15, 2015 at 2:07 PM, Lydia Pintscher lydia.pintsc...@wikimedia.de wrote: Thanks so much for the feedback.

I think we already got (imho) enough feedback and need to proceed best as possible (within our constraints) to satisfy what folks want. What I hear is that people like that the results in the special page are live (vs. cached) and they use the iwlinks filter. I think we can adjust how the query works to make if fast enough to not require caching (except maybe squid caching for a minute). Also, some people are interested in having results sorted by how old the page is (so people can find recently create pages, or other way around). For the most part, page_id provides this while also being better choice performance-wise. It is also consistent with how Special:PagesWithProps works. (Special:PagesWithProps is also pretty fast, thus it doesn't need to be a cached special page) I think we can also extend QueryPage so that we can make this information available in the api. (sorting by page title is not very suitable for QueryPage) and if for some reason we still need caching now or in the future, then it would be more easily possible if we extend QueryPage.
