Heiya Pavel, thank you so much for working on some quite popular extensions and making them fit for the future, e.g. MagicNoCache or NumberFormat. MPDF seems to be a cool one too though I have not tried so far. Cheers and kudos to you [[kgh]] (talk) 09:56, 30 November 2012 (UTC) (talkcontribs)

Dear All,

is there any chance to use mpdf with PHP 8.2 for mediawiki. Or if not, can someone recommend me an alternative extension?

Thank you very much and greetings

Suggestion to install 2 extensions to improve Wikimedia.

Correct title: Extension:MyVariables (talkcontribs)

Hello, why aren't those 2 extensions installed?, if both were installed, there would be less problems, when inserting __NOCACHE__, just loading the page again would show the current date of the pages without having to purge (since to purge a page we must be not blocked, otherwise an error will appear) with the second extension, and with the first we could show some messages for unregistered users and show other messages for users who are registered using {{#ifeq: {{currentuser}} | {{currentloggeduser}} | (registered user) | (not registered user) }}, Maybe you want to start a request to install the 2 extensions on phabricator? thanks

Mpdf crash on mediawiki docker

B8mhzmk (talkcontribs)


Thank you for maintaining Mpdf extension! I use latest stable mediawiki docker image, which has php8.1 installed. Hovewer, in your Mpdf extension you use now incompatible version of mpdf github.com/wikimedia/mediawiki-extensions-Mpdf/blob/96d573c96eaf88d33c50ee38c1fa4fd421eece10/composer.json#L3 which crashes when you try to export wiki page to pdf with many kind of errors.

The correct version of Mpdf for php8.1 would be v8.0.13 as written in github.com/mpdf/mpdf

Could you please update mediwiki Mpdf version? Thank you!

phptag cause internal error

Gadjodilofoo (talkcontribs)


it could be famous if it runs. Have you an idea what can cause this error, my mediawiki is a new creation.

MediaWiki 1.37.1

MySQL 8.0.28-0ubuntu0.20.04.3
ICU 60.2

Thank you for your attention.

Perhaps modsecurity of my shared server?

Something to do in .htaccess?

Varnish configuration for 5xx backend response

4 (talkcontribs)


at Manual:Varnish_caching you inserted a configuration snippet for Varnish to not cache 5xx backend responses. As far as I know Varnish doesn't cache this responses by default. Can you give my a hint why do you think it's important to insert this snippet anyhow? Thanks.

Pastakhov (talkcontribs)

Hi, I added it because my Varnish cashed 5xx backend response, and it was not very nice. (talkcontribs)

In a default configuration of Varnish 6.x (and also lower versions) it doesn't cache 5xx backend responses - have a look at the Varnish User Guide. I think this snippet doesn't change Varnish's behaviour in a default, untouched setup.

Pastakhov (talkcontribs)

I have no idea what you call untouched setup, but my Varnish version 5.2.1 revision 67e562482 cached 5xx backend responses until I added the rule to not cache it. Also I faced this problem several times on others wiki. Especially when SMW is installed and after you ran maintenance script a lot of pages were cached with the message that MW in maintenance mode. I'm really glad if your Varnish does not cache 5xx backend responses. But my experience says me that this rule should be added.

Multimap extension - mapping Google API

B1Bayon (talkcontribs)

Hi there Pastakhov, I've just recently tried setting up Multimap, and was hoping to use it with Google Maps, however now google maps require API. Was wondering if you had a solution to this or any new extensions that may accommodate embedded google maps on the wiki page.

Look forward to hearing from you.

Hello Pastakhov, I've been working on skinning and your page Skin:Empty regularly comes up as the #1 Google hit, but it seems to be an abandonded draft. I was wondering if you wanted to move the draft to userspace or if the page should maybe be deleted – I think it's the only page in the Skin namespace that doesn't describe a skin that exists.

Pastakhov (talkcontribs)

Hello @Þjarkur, I just have no time to finish the Empty skin, generally the skin works but I didn't created useful PhpTags widgets for the skin and mw core does not support less as a wiki page yet... but I still plan to finish it in a few months

Extension MultiMaps: T210033

Pastakhov (talkcontribs)

Oh, thank you for your contribution, I'll review it. Sorry, I'm hard busy and missed your patch, thanks for the message.

FellTiger (talkcontribs)

Sorry, to bring this up again, but I am afraid that I will forget more and more why I implemented some things the way I did. Additionally, most of the changes are white space changes. I pushed all the files I edited through a style fixer, so that they comply with the coding conventions.

In case you have lost interest in this extension, I can also offer to become the maintainer, but I would not prefer that because I do not have a lot of experience with MediaWiki coding and PHP in general.

Please let me know what you think!

Pastakhov (talkcontribs)

I'm interesting in the extension and I am grateful for your contribution, but I'm on a trip currently and can't review the patch, sorry. I will be available soon. thank you for your patience and bringing it up.

Hi FellTiger, you are right, it goes beyond the limits of decency, my sorry for delay... I will help right now
