PostgreSQL - MD5 instead of SCRAM Authentication

Summary by

شحن جواهر يلا الودو العاب عن طريق ايدي (talkcontribs)

Is it possible tho change the used Authentication method when connecting to a PostgreSQL 13 Server from SCRAM to MD5?

(Win 2019 IIS; PHP 7.3.24; PostgreSQL 13)

I've already changed pg_hba.conf to MD5 auth, but mw-config is still trying to connect via SCRAM (which seems to not be OOB supported in recent PHP 7.3.24 Windows binarys) throwing this error:

Cannot access the database: Unable to connect to PostgreSQL server: SCRAM authentication requires libpq version 10 or above

MarkAHershberger (talkcontribs)

After changing the authentication method, you have to set password_encryption = md5 in postgresql.conf too. Restart PostgreSQL and then change the password to get it encrypted in the new method. (talkcontribs)
  1. Open the psql console. To do so, click StartPostgres 13SQL shell.
  2. Log in to the local cluster and run the command:

ALTER SYSTEM SET password_encryption = 'md5'

  1. Update the password of the postgres user by running the following command:

ALTER ROLE postgres PASSWORD '<new password>'

  1. To make sure that the password is saved using the supported algorithm, run the command:

SELECT passwd FROM pg_shadow WHERE user = 'postgres'

  • A line with the encrypted password will appear. The line starts with MD5, for example: md533a9a79ffee1cc8bf4fbc63f24518e44.

now you should be connected to pgsql db. (talkcontribs)

[RESOLVED] After Update Error: 1054 Unknown column 'ug_expiry' in 'field list' (localhost)

Nelodie (talkcontribs)


After a upgrade of Ubuntu ( to 16.04) My dear wiki developped on mediawiki 1.23 was not work. After some search on web, I decided to update also mediawiki to last version 1.29 by following all instructions described in Update manuel.

So basicaly, I dump my DB, save in tar.gz files before download the mediawiki-1.29.1.tar.gz.

After all my images folder was copied and extensions are updated I run also the update.php script wiith no error.

The first run my wiki home page I obtain just a error about "wfLoadSkin( 'Vector' );" forgotten. So I modified correctly the LocalSettings.php file and run again the home page of my wiki... but I have this SQL error 

6e1e893ddacaf2198378f128] /wiki/index.php/Accueil Wikimedia\Rdbms\DBQueryError from line 1075 of /var/lib/mediawiki/includes/libs/rdbms/database/Database.php: A database query error has occurred. Did you forget to run your application's database schema updater after upgrading? 

Query: SELECT ug_user,ug_group,ug_expiry FROM `user_groups` WHERE ug_user = '31' 

Function: UserGroupMembership::getMembershipsForUser

Error: 1054 Unknown column 'ug_expiry' in 'field list' (localhost)

I was tried to update manually the DB by dump but the error stay.

Could you help me ?

Thanks you very much @Osnard

I  applied manually your SQL Code and the wiki appeared and worked fine.

I ran into this when I tried to upgrade with Flow enabled. Disabling Flow temporarily allowed the upgrade o work.

Kghbln (talkcontribs)

I ran into this when using a foreign file repo via the ForeignDBRepo class. The providing wiki was updated to 1.35 the receiving wiki was still at 1.31. After also updating the receiving wiki to 1.35 the error went away.

Kghbln (talkcontribs)

Oops, actually in my case the issue was Error: 1054 Unknown column 'img_description' in 'field list' (localhost)

I loaded the Visual Editor extension. But when I select edit, I get the following error. I am using MediaWiki 1.37.1. According to the documentation (Extension:VisualEditor), it appears that once you load the VisualEditor extension, no further configuration is needed unless I am missing something. Any thoughts?

Error Message

Error contacting the Parasoid/Restbase server: http-bad status.

Unfortunately parse.php --help fails with the following error so the debugging tools are not helpful.

Toastronaut (talkcontribs)

I'm facing a similar issue with 1.37.1. The specific error message I get is Parsoid/RESTBase timeout was reached. I am running this through the official docker image with a private wiki setup. I've also tried the parse.php script and got the same error as @Wolfcu69.

I tried the php bin/parse.php --integrated line from the same page and got an error that Parsoid wasn't loaded. I tried loading the Parsoid extension explicitly in LocalSettings.php, but that didn't work. That makes me think the original error that Parsoid wasn't loaded is an issue with the parse.php script.

I found a number of issues with 1.35 that mention the same error, but they all recommend changing the $wgVirtualRestConfig['modules']['parsoid'] value. As far as I understand, that shouldn't be necessary with 1.37.1. (I tried the changes anyway and got nowhere).

Hello, I have the same with mysql database and the wikimedia 1.37.1, I have a "Parsoid/RESTBase server (HTTP 500)" error , I don't have any other specification.

Visual Editor does not Show Recent Uploads List to Insert an Image

Bccrowe (talkcontribs)

MediaWiki 1.37.1 (Mac OS Monterey, install in place with MAMP, standard set of extensions)

Mac OS 12.1, MAMP 6.6 (1211), PHP Apache 7.4.21, MySQL 5.7.34

I am new with just a few days playing with MediaWiki. I am trying to create a media-rich wiki. File uploads work, and Special Pages show the related file statistics correctly. Using the Visual Editor, when I select: Insert -> Image, the table to select a recent uploaded image to insert is empty. If I use the Source Editor, I can successfully add the image explicitly. Any idea about why this is not quite working? Is there a privilege setting I need to make somewhere?

Thanks to anyone who can help me!

Bccrowe (talkcontribs)

Any ideas, anyone?

I'd like to be able to delete nearly every user on my wiki - probably "every user which has never made an edit" - or "every user who has only edited his own user page".

Is there an extension that could do this? Or a tried-and-tested SQL query?

Thanks in anticipation.

AhmadF.Cheema (talkcontribs)

The most appropriate way to achieve something similar is by way of Extension:UserMerge. The more customized solutions, either don't exist or are likely to be very unreliable.

Jonathan3 (talkcontribs)

Thanks. That extension doesn't look useful for removing (or merging) hundreds of users. Its page has a link to Extension:BlockAndNuke but that's not maintained and from the talk page looks not to be working with the latest MW version.

Jonathan3 (talkcontribs)

Back to SQL, do you think the following would work? The intention would be to delete every user from the user table who has never made a revision which appears in the revision table.

FROM wm_user 
WHERE user_id NOT IN (SELECT DISTINCT rev_user FROM wm_revision)

There are no pages in the User or User Talk namespaces to worry about having to delete.

Jonathan3 (talkcontribs)

@Samwilson I saw you reply to another message about users, and wondered if you would be able to help with my (SQL) query above. Thanks in anticipation.

Samwilson (talkcontribs)

I'd recommend against trying to do this directly with SQL. It's really likely to be a headache.

I suspect that getting the BlockAndNuke extension up to date would be easier, and result in a more reliable solution that's more usable by more people. :)

(I might have a look at it this weekend...)

Deimos (talkcontribs)

>> every user which has never made an edit

Well, this is simple. Just run the maintenance script 'RemoveUnusedAccounts.php' - Manual:RemoveUnusedAccounts.php

This post was hidden by 94rain (history)
Jonathan3 (talkcontribs)

Thank you very much. I'll look into it as soon as I get a chance! Because of the settings on my wiki, the spam accounts get created but don't edit pages, so this looks like the right solution for me.

Meanderpaul (talkcontribs)

i know zombie thread and stuff. I ran the removeUnusedAccounts.php and found and removed over 88k users. (got a massive spam attack and have since added captcha)

when i go onto mu wikipage and view user lists it still hows 1000s of users that need to be removed. is there another option for getting rid of them? as a bonus if you can remove pages that they made under the talk option.

Large Gallery thumbnails not always shown

2001:4452:301:C600:5C63:1D8:FD3E:F9B (talkcontribs)

The problem: when having a gallery with a significant amount of images - they're not loaded.

Which wiki this happening on?

specific link:

What I've done so far: Tried to communicate with the support of (they seem to not know either)

More detailed: between 00:00 and 04:00 western pacific time I can load that page without problems. All images are shown. Around 06:00 it starts to get worse with some images not being shown anymore this gets worse through the day..

I verified large sites with galleries hundreds of images on they have no problems with hundreds of images in a gallery.

How does a proper image being shown:

  • <a href="/proxy/" class="image"><img alt="" src="/proxy/" decoding="async" width="80" height="44" srcset="/proxy/ 1.5x, 2x" /></a>

    G8-3 And what does it look like for the failed images:

  • G8-2 Any idea why this behavior is happening?

  • Malyacko (talkcontribs)

    Cannot reproduce. Images load when going to that link. If there are certain issues at certain times, you will have to contact the folks who run that wiki (we don't run it).

    Jonathan3 (talkcontribs)

    I don't know the answer but could reproduce the problem... I checked at about 2300 GMT and there were quite a few images missing. Mostly ones nearer the bottom of the page. Purging that page with ?action=purge took absolutely ages but after doing it twice the images appeared.

    Bawolff (talkcontribs)

    I can't even get that page to load.

    InstantCommons is really slow. Maybe its hitting some sort of timeout.

    I would suggest enabling mediawiki debug logging. (talkcontribs)

    Your web server might have a limit on the download size.

    Bawolff (talkcontribs)

    That's unlikely as they are missing html in the middle of the page. A download limit would cut off the entire thing, or at some point, not just garble random parts in the middle. (talkcontribs)

    The people running the web server probably limit the download size (or there is a timeout) depending on the time of day.

    Bawolff (talkcontribs)

    If some servers (maybe job queue) are behind a firewall and some aren't, what could be happening is only some servers can fetch metadata from commons. Only some images would be broken because some would be cached from previous renders, but more would become broken over time. Although if that was the case, i would expect the broken images to be random and not towards the end.

    Mrgenie (talkcontribs)

    It is assumed this only happens to 'some' servers.

    That's an incorrect assumption without evidence to that assumption.

    Below I'm adding the evidence this isn't just an issue on smaller servers


    Scroll down and you get the same error - so it also happens on the "big"

    TheDJ (talkcontribs)

    @Mrgenie That specific page has an insane amount of images... you are bound to hit ratelimits I think with that many images (even without the overhead that OSM has by using InstantCommons). There is a reason a category only shows you a max of 50 images normally. My browser can't even keep all of them in memory, if I scroll I can see them being dropped/reloaded into the renderer. Oh, now the tab crashed.

    I pity the mobile user who accidentally clicks this page ;) As a developer, it's making me wonder if we should put a limit on the amount of images you are allowed to add to pages.

    If you push the limits you might crash, this page is pushing the limits. (talkcontribs)

    It's interesting your browser can't keep them in memory.

    The Philippines Road Sign lookup table

    This is the page the original talk started about. It's about 300 images, each 10 to 50kb.. but let's stick to 100kB per image, although not a single image is 100kB

    So the total is 30MB, if we assume 100kB per image. I believe my old i386 back in the stone age already could do up to 4GB RAM LOL

    But okay, if you say your 21st century equipment can't put 30MB in the memory - I guess some people still running Commodore C64/128 or so.

    And that's okay, I get it, every single person I tried to convince there shouldn't be a problem like this - insists that it's normal that things not work - and the failure to load a few MB over the internet is normal, that's the way it should work. So I gave up trying to convince MediaWiki devs that this is not how it's supposed to be.

    No one will fix this and it's normal that a gallery of a few hundred images doesn't work and there's nothing wrong with mediawiki. No bugs or anything, it's supposed not to work! LOL

    Funny thing though - when I click "edit" all images are loaded instantly without any hiccups..

    but when the user uses the "read" - as in a person not editing the wiki page - then it doesn't work. But yeah I get it, it's supposed not to work for those people using wiki pages. Only those that edit wiki pages it's suppose to work.

    Anyway - feel free to close this issue. Wiki folks already explained to me if the "edit" works and the "read" doesn't work, that's exactly how it's supposed to be working and means 100% working fine and no bug. So I simply leave it at that.

    Ciencia Al Poder (talkcontribs)

    Note that the file size is only the amount of size it takes in storage, but not in actual memory. An image displayed on screen needs a lot more memory. Most images use compression techniques to reduce the file size to optimize for delivery, but uncompressing and rendering them on screen takes CPU cycles and memory.

    Bawolff (talkcontribs) (talkcontribs)

    Yeah that is actually helpful - but I'm not managing the server and the person who is - is not interested in installing a beta package to see if it speeds up things.

    So we have no idea how it'll impact these galleries having these issues - until it's released.

    Hello, I've encountered an issue that I'm not getting solved on my own after upgrading from 1.35.2 to 1.36. Following text can be seen on the background of any page on the whole wiki:

    Okay, so typing in error_reporting( 0 ); in my LocalSettings.php right underneath <?php solved it.

    Rasputin1493 (talkcontribs)

    However, these errors are obviously not gone and affect the functionality of the wiki big time.

    So how to fix that?

    Tenbergen (talkcontribs)

    Having lots of deprecated errors like that in my logs as well after updating to 1.36.0. Did you end up getting a solution, Rasputin1493?

    Tenbergen (talkcontribs)

    I finally managed to track it down to Semantic Mediawiki - when I disable that, the errors go away. I have started a ticket with them.

    TiltedCerebellum (talkcontribs)

    Per the sidebar on this wiki page, you might need to turn on detailed debugging and give more complete error messages with stack trace for folks to be able to help you determine what's going wrong. Usually the full stack trace gives them much more info.

    I experienced it trying to use Monobook, Timeless and Splash skins, but it seems this bug happens in a lot of situations.

    • Here it was related to EmbedVideo extension.
    • Here the bug happened using ArticleRatings extension
    Tenbergen (talkcontribs)

    That's interesting. I am using Monobook exclusively as well. And now that you say it... I tried to download a beta version a few weeks ago and had to disable Monobook to make it work at all. Didn't have time to fuss with it further then, so never installed it on my test system. OK, I have enabled Vector on my wikis and set it to default. Still getting these errors. So, likely not just a Monobook think after all.

    I'm trying to accomplish something similar to the Minecraft wiki, where they use 1 large image with thousands of tiny sprites, only rendering a small section of the image, instead of uploading thousands of images. However, I see that the SpriteSheet extension Extension:SpriteSheet is no longer updated and doesn't work on the newest version. It appears the Minecraft wiki uses a whole bunch of templates, modules, and widgets, and I tried copying them to my wiki, however this didn't seem to work. Are there any other alternatives to accomplish this?


    Ciencia Al Poder (talkcontribs)

    You can do this with CSS, using the image as a background-image, with a different background-position for each item, and setting a defined width and height to the element that will display the image.


    For setting a background-image I'd recommend using Extension:TemplateStyles, although you can define it in MediaWiki:Common.css as well. The other CSS properties can be set inline. You can use a template for this, with a big switch, or even better if you use a Lua module (you can define all the data in json).
