Re: [MediaWiki-l] still questions about thumbnails and previews

Hi John, I used to have no wgUploadDirectory settings in LocalSettings.php. I left it default. Recently, I tried $wgHashedUploadDirectory = true; . But neither of them works.

Thumbnails when logged, but no thumbnails for anonymous readers
by Jeff Darlington 10 Aug '16

10 Aug '16

I currently maintain a wiki where I am the sole sysop and editor, but the wiki is publicly accessible for read-only access. I'm not sure how long this has been going on, but I've recently noticed that when I'm not logged in, I'm starting to get "Error creating thumbnail: Unable to save thumbnail to destination" errors on pages that contain images. This sounded similar to some recent messages I've seen on the list about thumbnails not working, so I started doing some digging. What's *really* interesting is that, as soon as I log in, the images start working correctly! The effect is completely repeatable: If I log in, the image displays fine; once I log out, the thumbnail error reappears. Naturally, I've already checked to make sure ImageMagick is properly installed and working correctly; after all, it's creating thumbnails fine when I'm logged in. I've also checked the file permissions to my images folder and it is writable by the Apache user/group. What baffles me most is why the thumbnails would work fine when I'm logged in, but fail when I'm not; from the web server perspective, permissions shouldn't be an issue since everything would be operating under the Apache context. Clearing the file cache (php rebuildFileCache.php) and the images (php rebuildImages.php) has no effect. MediaWiki: 1.27.0 PHP: 5.6.15 (apache2handler) MariaDB: 10.0.21-MariaDB ICU: 52.1 ImageMagick: 6.8.8.10 Any ideas? Jeffrey T. Darlington General Protection Fault http://www.gpf-comics.com/

Re: [MediaWiki-l] Data Import
by Jan Steinman 09 Aug '16

09 Aug '16

> I am privately hosting a public wiki (Media Wiki 1.27.0). The data sits in a local MySQL database. I want to populate the wiki pages with this data. I am unable to find any documentation to solve this. Please sen links or info. Best Regards, Khaled Soubani. The nature of the data you wish to import is unclear, as is the desired presentation. Is this data an existing MediaWiki site? If so, I would try upgrading the existing MediaWiki, and it should convert the data, which you can then import into the new wiki using standard SQL techniques. If you want to present other MySQL data alien to MediaWiki, I have an extension that may be useful to you that allows tabular display from standard SQL statements, maintained from within MediaWiki. It has some nice enhancements, like pagination and being able to keep a running total, eliding long texts, and basic (non-resizing) image display. Here is an example: http://www.EcoReality.org/wiki/Dairy_production/15 Let me know if you want the extension and I will email it to you. I’d post it in the MediaWiki extensions library, but I’m always working on it… :-) Jan Steinman EcoReality Co-op, http://www.EcoReality.org 2152 Fulford-Ganges Road Salt Spring Island, BC V8K 1Z7 CANADA +1 250.653.2024

cldr not installing properly
by Andrew Geary 09 Aug '16

I am attempting to install cldr. In previous installations, I have not had any issues with this extension and is currently live at wiki.seg.org.

Problem with brackets in page links
by Martin Brunner 07 Aug '16

07 Aug '16

Hi! I also run an own Mediawiki, but the problem is that many browsers do not encode the brackets correctly if you copy and paste the URL. Actually only Firefox/Seamonkey seems to do it right. For example: The correct link URL for pasting into a mail: https://en.wikipedia.org/wiki/Amsterdam_%28disambiguation%29 The URL displayed in the browser, and copied by most browsers: https://en.wikipedia.org/wiki/Amsterdam_(disambiguation) The problem now is, that many mail clients (such as Outlook Web-App) won't recognize the ) being part of the URL and just will open https://en.wikipedia.org/wiki/Amsterdam_(disambiguation on click - which does not work of course. So this might be a failure of most browser or mail clients - but can this be solved via Mediawiki? Regards Martin

Cannot link SVG thumbnails?

I'm getting this error when I load the page of an uploaded SVG file: *Error creating thumbnail: Unable to create temporary thumbnail file* In the wiki's debug log I'm also getting: File::transform: Doing stat for mwstore://local-backend/local-thumb/7/71/WorkInProgress_DocumentIcon.svg/185px-WorkInProgress_DocumentIcon.svg.png FileBackendStore::getFileStat: File mwstore://local-backend/local-thumb/7/71/WorkInProgress_DocumentIcon.svg/185px-WorkInProgress_DocumentIcon.svg.png does not exist.

How can I debug this issue more? Thumbnails seem to work fine for all other formats. Kind regards, Manu

Category weirdness
by LCJones 06 Aug '16

06 Aug '16

Folks, Here's what I'm running on Ubuntu 16.04 with nginx. It's a play box as I experiment with hhvm among other things. This mediawiki instance is being built as a genealogy project. Product Version MediaWiki 1.28.0-wmf.13 HHVM 3.14.4 (srv) MariaDB 10.1.16-MariaDB-1~xenial ICU 55.1 LuaSandbox 2.0.12 Lua 5.1.5 Elasticsearch 2.3.5 At first set up I created pages for individual people and created a category based on the surname. The people with same surname, i.e., Jones, would then be listed together in the correct category [[Category:Jones]]. Then I created a master "Surname" category in which all the surnames are listed which in turn made the [[Category:Jones]] to become a sub-category. However, for some reason, which I can't seem to resolve, pages are not being added to categories now. So if I create a new person page and then create the [[Category:$urname]] the page is not being added to the new category. Examples can be seen here: Working http://wiki.jonesipedia.com/wiki/John_Beaty_Sr._1661_-_1720 http://wiki.jonesipedia.com/wiki/Category:Beaty Non-working http://wiki.jonesipedia.com/wiki/Elizabeth_Ann_Ledford_1870_-_1965 http://wiki.jonesipedia.com/wiki/Category:Ledford I've checked debug and log files and can't seem to find anything wrong. So I am wondering if anyone else has run into this and/or if there is a fix I can try. Thanks, Chap
