In some recent version of MW (have noticed in 1.24wmf17, but possibly before?), the "Next" link(s) no longer appear on Special:AllPages. Strangely, "Previous" links are provided (once you actually search for something), even if one has not actually come from any previous page! It is not at all what users (new or old) would expect. This is a significant loss of usability. Users can no longer just click through to continue the page list; they have to copy the last page title in the list, paste it into the "Display pages starting at:" box, and hit "Go" again. Terrible. If you need a specific example, see: https://www.mediawiki.org/wiki/Special:AllPages BTW, Special:PrefixIndex has a "Next" link (when appropriate), but no "Previous" link once you get to the next page. A less serious problem, of course, since the user can always use their browser's "Back" button, but still... seems strange. (Note: I guess this technically constitutes a return to the very ancient bug 1331. Maybe I was supposed to just reopen that one??)
There is also missing overview page. Recently there was first page with some groups like * !-Beef * Beef-Guam * Guar-Yello * Yellow-some_special_character so users were able to go to requested page with clicking only (no typing) and it was usable for checking from which letter there are more or less articles.
That was shown when the wiki had more than a certain number of articles (I don't know what the threshold was). For extremely large wikis, there were multiple levels of such index pages (or whatever the technical term is for them). That is, one such "range of articles" link, say, Actinium-Bookcase, would lead to another list of "range of articles" links, say, * Actinium-Archive * Archos-Asterisk * ... * Boardwalk-Bookcase Yeah, those are gone now, too.
This problem still exists, can it please be solved. Special:AllPages is now almost useless or totally clumsy in use.

You were correct to file this bug. It's a very good bug report. Thanks. :-) We're presumably talking about https://git.wikimedia.org/blob/mediawiki%2Fcore.git/HEAD/includes%2Fspecials%2FSpecialAllPages.php though I wouldn't be surprised if the pagination logic were shared... I'll poke at this.
Right, so https://gerrit.wikimedia.org/r/145761 did this (specifically <https://gerrit.wikimedia.org/r/#/c/145761/1/includes/specials/SpecialAllPages.php,unified>). It removed the $n++ line, which is later used at <https://git.wikimedia.org/blob/mediawiki%2Fcore.git/HEAD/includes%2Fspecials%2FSpecialAllPages.php#L307>: if ( $n == $this->maxPerPage && $s = $res->fetchObject() ) { Because $n isn't getting incremented any longer, it never equals $maxPerPage (which is set to 345... no idea why, probably aesthetics).
