MySQL 8.4+ Compatibility

MySQL 8.4 has changed the way auto_increment works. Will this affect MediaWiki compatibility?

Data Types & Constraints: 8.4 prohibits AUTO_INCREMENT on FLOAT/DOUBLE columns. Molsen7970 (talk) 18:16, 5 May 2026 (UTC)

MySQL 8.4 was released more than two years ago, not sure why you'd ask now? Compatibility implies compatibility. Malyacko (talk) 10:51, 12 May 2026 (UTC)

The highest version of MySQL listed on the compatibility site is MySQL 5.7.0+. I assume the plus at the end means 8.4 is compatible with Mediawiki 1.43.8 because of the "+" but there seems to be a difference between MySQL 5.7 and 8.4 in the way AUTO_INCREMENT works. We were curious if Mediawiki uses AUTO_INCREMENT in a way that would break when we upgrade to MySQL 8.4. (MySQL 8.0 LTS ended last month which is why we are upgrading to the next LTS, 8.4.) Molsen7970 (talk) 20:21, 19 May 2026 (UTC)

We had this same debate about ambiguity in relation to PHP versions a while back. In that case, "PHP 8.1.0+" did not (at the time) include PHP 8.4. See Talk:Compatibility#PHP_8.4_is_missing_(in_compat_matrix). However, one comment which was wrong in one sense (the truth is "It's hoped that things above it are supported" rather than "everything above is supported") might answer your question here: "e.g. in the database matrix is says MySQL 5.7.0+. For me that means that everything above is supported. e.g. I'm using MySQL 8.4 and mediawiki runs on it" :-) Jonathan3 (talk) 15:24, 23 May 2026 (UTC)

Wikipedia and MediaWiki.org are still using 8.3. Flounder ceo (talk) 14:52, 3 June 2026 (UTC)

How to get my user name from Lua ?

Is it possible to get my user name using Lua? I tried this:

mw.config.get('wgUserName')

but that only returns "attempt to index field 'config' (a nil value)". - Erik Baas (talk) 06:05, 21 May 2026 (UTC)

It's not, lua is there for wikitext processing, and mw.config doesn't even exist there (it's a JS API) Archimedes5000 (talk) 01:53, 22 May 2026 (UTC)

I think there are extensions that could return the current user's username, and I expect you could use one of them via Lua. Jonathan3 (talk) 15:17, 23 May 2026 (UTC)

You could use Help:Magic words#REVISIONUSER, e.g. mw.getCurrentFrame():preprocess("{{REVISIONUSER}}"), but you can't get the current reading user because then the rendered wikitext would have to be cached separately for each viewer. Sam Wilson 11:24, 30 May 2026 (UTC)

Photo Media

Hi Gramps

Please forgive me in advance as I'm no the brightest globe.

I am investigating media storage in my Gramps database and have found what appears to be inconsistent media file referencing.

My media files are stored under a main FAMILIES directory with surname-based subdirectories. For example:

FAMILIES\KOZUBEK@ File KOZUBEK Erna Clara 1938-1999\Pho KOZUBEK Erna Clara 1938-1999.jpg

Many media records in Gramps correctly reference files using their original directory structure and filenames.

However, some media records reference files using a different structure where the path begins directly with the root media folder in uppercase, for example:

FAMILIES\0122343ecbe74c60c28bf4d68b4561c8.jpg

These files exist in the FAMILIES directory and open correctly, displaying the expected image. The media record is therefore working, but I do not understand why Gramps is referencing a generated filename instead of the original path and folder structure.

I have identified approximately 385 files with similar generated hash-like filenames in the FAMILIES directory.

For example, the media associated with Erna Clara KOZUBEK points to:

FAMILIES\0122343ecbe74c60c28bf4d68b4561c8.jpg

rather than:

Family\KOZUBEK@ File KOZUBEK Erna Clara 1938-1999\Pho KOZUBEK Erna Clara 1938-1999 i0041.jpg

Questions:

1.      Is there a recommended method to restore media records to the original directory structure?

Any guidance would be appreciated.

@~2026-32090-74: You're reporting this on the wrong website, sorry. Gramps uses MediaWiki, but it sounds like your issue is with Gramps itself. Try https://gramps-project.org/wiki/index.php/Using_the_bug_tracker Sam Wilson 05:09, 30 May 2026 (UTC)

Mediawiki Migration Issue 1.35.0 to 1.45.3

I am migrating a private wiki I run from version 1.35.0 to 1.45.3 by restoring the SQL database. When I run update.php it fails when trying to change templatelinks .

Error messages:

Modifying tl_namespace field of table templatelinks...Wikimedia\Rdbms\DBQueryError from line 1225 of /var/www/mw/includes/libs/rdbms/database/Database.php: Error 1054: Unknown column 'tl_target_id' in 'templatelinks'

'''Function: Wikimedia\Rdbms\Database::sourceFile( /var/www/mw/sql/mysql/patch-templatelinks-tl_title-nullable.sql ) '''

'''Query: ALTER TABLE `templatelinks` '''

'''CHANGE tl_target_id tl_target_id BIGINT UNSIGNED NOT NULL'''

1.35.0 site is fine and runs update without a problem and there is a primary key in templatelinks when update.php starts but then after run it is gone. I do not know what tl_target_id is?

Johnny Wunder JohnnyWunder (talk) 19:46, 1 June 2026 (UTC)

@JohnnyWunder: You must first upgrade to 1.39. If you're not aiming to upgrade often, it's probably best upgrade to each LTS release in turn (every two years). See Manual:Upgrading#Check_requirements for more info. Sam Wilson 05:43, 2 June 2026 (UTC)

Thank you that fixed it JohnnyWunder (talk) 13:38, 3 June 2026 (UTC)

Problem afret installation and login...

After I installed mediawiki on synology DSM system (whole package there is prepared), I cannot login as a admin to media wiki. I am sure, that I am using right username and passwd, which I used during installation mediawiki. I tried it a fewtimes, but the same result - wriong username or password. :-( Zdenek.zemek (talk) 06:28, 3 June 2026 (UTC)

@Zdenek.zemek: Have you tried doing a password reset? If that's not working (e.g. you don't have an email address on the account, or emails cannot be sent by the system), see Manual:Resetting passwords for more ways to reset the password. Sam Wilson 09:20, 3 June 2026 (UTC)

Yes, I tried it, but not work... no e-mail came to me for password reset... :-( But it seems, that I solve it by install it due docker tool. But for now I did wiki.js installation... we will see it is enough... due docker, I can try install media wiki also... if it is better, I think YES :-) Zdenek.zemek (talk) 13:51, 3 June 2026 (UTC)

Internal Server Error

I installed a fresh Wiki (from MediaWiki) on a Strato-hosted webspace into a fresh db, which is again and again running into Internal Server Error. My version can be found here:

MediaWiki	1.45.3
PHP	8.4.21 (cgi-fcgi)
ICU	58.2
MariaDB	11.8.5-MariaDB-log
Lua	5.1.5
Pygments	2.19.2

When Internal Server Error comes up I switch the php-version within a range of 8.2 to 8.5 and all is running fast again. It takes a little time, but then again the wiki stuck into Internal Server Error. The Wiki can be found here: www.helmstedt-wiki.de – Maybe someone can help me get out of this? Mirko Marhenke (talk) 11:49, 7 June 2026 (UTC)

@Mirko Marhenke: Have you looked through Manual:How to debug? You should be able to get a clearer error message. Sam Wilson 12:02, 7 June 2026 (UTC)

I got this now from putting $wgShowExceptionDetails = true; into LocalSettings.php:

Deprecated: Automatic conversion of false to array is deprecated in /mnt/web115/e0/92/5517492/htdocs/c_helmstedt-wiki_2026/LocalSettings.php on line 44 Warning: session_name(): Session name cannot be changed after headers have already been sent in /mnt/web115/e0/92/5517492/htdocs/c_helmstedt-wiki_2026/includes/Setup.php on line 487 Warning: session_id(): Session ID cannot be changed after headers have already been sent in /mnt/web115/e0/92/5517492/htdocs/c_helmstedt-wiki_2026/includes/Setup.php on line 533 Warning: session_start(): Session cannot be started after headers have already been sent in /mnt/web115/e0/92/5517492/htdocs/c_helmstedt-wiki_2026/includes/Setup.php on line 534 Warning: Cannot modify header information - headers already sent by (output started at /mnt/web115/e0/92/5517492/htdocs/c_helmstedt-wiki_2026/LocalSettings.php:44) in /mnt/web115/e0/92/5517492/htdocs/c_helmstedt-wiki_2026/includes/Request/WebResponse.php on line 69 Warning: Cannot modify header information - headers already sent by (output started at /mnt/web115/e0/92/5517492/htdocs/c_helmstedt-wiki_2026/LocalSettings.php:44) in /mnt/web115/e0/92/5517492/htdocs/c_helmstedt-wiki_2026/includes/Request/WebResponse.php on line 69 Warning: Cannot modify header information - headers already sent by (output started at /mnt/web115/e0/92/5517492/htdocs/c_helmstedt-wiki_2026/LocalSettings.php:44) in /mnt/web115/e0/92/5517492/htdocs/c_helmstedt-wiki_2026/includes/Request/WebResponse.php on line 69 Mirko Marhenke (talk) 12:18, 7 June 2026 (UTC)

@Mirko Marhenke: What is on LocalSettings.php line 44? Sam Wilson 12:22, 7 June 2026 (UTC)

From 44 on is

$wgLogos['wordmark'] = [

  'src' => "$wgScriptPath/resources/assets/helmstedt-wiki-wordmark.svg",

  'width' => 120,

  'height' => 30,

];

# $wgLogos = [

# '1x' => "$wgResourceBasePath/resources/assets/change-your-logo.svg",

# 'icon' => "$wgResourceBasePath/resources/assets/change-your-logo.svg",

# ]; Mirko Marhenke (talk) 12:23, 7 June 2026 (UTC)

@Mirko Marhenke: You probably need to define the whole structure of $wgLogos, e.g.:

    $wgLogos = [
        'wordmark' => [
            'src' => "$wgScriptPath/resources/assets/helmstedt-wiki-wordmark.svg",
            'width' => 120,
            'height' => 30,
    ];

(I'd also recommend not storing helmstedt-wiki-wordmark.svg in the main resources directory, as it might get overwritten when you upgrade.) Sam Wilson 13:10, 7 June 2026 (UTC)

OK, thank you. I'll try this, and otherwise come back here. Mirko Marhenke (talk) 13:25, 7 June 2026 (UTC)

Solved for now. Using standard parameters to logo settings. Mirko Marhenke (talk) 15:06, 7 June 2026 (UTC)
