• https://www.mediawiki.org/wiki/Manual:$wgConditionalUserOptions

I believe we will need to add new conditions as part of this ticket.

Questions:

• Is CUDCOND_ANON a defined condition or we need to request to be added, or is addressing it part of the ticket?
• What are the specific technical details for implementing and storing the default settings (e.g., within code only or utilising a config file such as skin.json file)?
• How and when will the deployment of the new default settings for users be carried out?
• Are there any specific testing or validation criteria that should be considered during the development process?

[mediawiki/core@master] Add new conditional default for user options: anon

https://gerrit.wikimedia.org/r/1016024

I have left some suggestions/questions on the patch

Moving back to doing to address the comments around temporary user accounts and add the second requested condition

Martin kindly offered to review this.

Martin +2ed the patch (thank you!), so this just needs a patch for Vector to make use of the new functionality :)

I can review it when it is ready, or write it if needed

[mediawiki/skins/Vector@master] Update font size defaults for named and anonymous users

https://gerrit.wikimedia.org/r/1017164

@SToyofuku-WMF, @Jdlrobson - just edited the task description to clarify that we will be changing the defaults themselves in a separate ticket. Apologies for the confusion! For this ticket, we just want the ability to have different defaults, but aren't ready to apply them just yet

Change #1017345 had a related patch set uploaded (by Jdrewniak; author: Jdrewniak):

[operations/mediawiki-config@master] [beta] Set Vector 2022 font-size to 16px on beta

https://gerrit.wikimedia.org/r/1017345

✅ The accessibility settings menu must have the ability to set different defaults for logged-in and logged-out users on desktop

I've confirmed this functionality locally by doing the following:

Added these two lines to my localSettings.php

	$wgDefaultUserOptions['vector-font-size'] = 1;
	$wgConditionalUserOptions['vector-font-size'] = [ [ 0, CUDCOND_NAMED ] ];

Which should set the default font-size for anonymous users to 16px, and logged-in to 14px.
I observed that

• The font-size for anons changed to 16px.
• The font-size for logged-in users who had changed their font-size, did not change.
• The font-size for logged-in users who had not changed their font-size, did change.

✅ In the future, both font sizes should be able to default to standard

The options worked with small, medium and large font-size (options 0,1,2).

❌ We must have the ability to set a different default size for new accounts vs existing accounts

With the following config, I wan't able to change the font-size for newly registered users, (not sure if I'm using this config correctly).

$wgDefaultUserOptions['vector-font-size'] = 1;
$wgConditionalUserOptions['vector-font-size'] = [
	[ 0, [ CUDCOND_NAMED ] ],
	[ 2, [ CUDCOND_AFTER, '2024010100000' ] ]
];

✅ We must have the ability to set a different default size for new accounts vs existing accounts

Update: my config was missing a "0". The following config does work and changes the font-size for newly created accounts (tested for accounts created in 2024).
Note: It's important that the newly created account option come first since these conditional options are evaluated in order (and newly created accounts are also logged-in accounts).

$wgDefaultUserOptions['vector-font-size'] = 1;
$wgConditionalUserOptions['vector-font-size'] = [
	[ 2, [ CUDCOND_AFTER, '20240101000000' ] ],
	[ 0, [ CUDCOND_NAMED ] ],
];

Thank you so much for reviewing @Jdrewniak!!

Change #1017164 abandoned by Stoyofuku-wmf:

[mediawiki/skins/Vector@master] Update font size defaults for named and anonymous users

Reason:

Abandoning this for now as we don't want to change defaults for anybody yet - we'll continue this work potentially in beta or in a follow-up ticket and patch

https://gerrit.wikimedia.org/r/1017164

Change #1017345 merged by jenkins-bot:

[operations/mediawiki-config@master] [beta] Set Vector 2022 font-size to 16px on beta

https://gerrit.wikimedia.org/r/1017345

@Jdrewniak / @SToyofuku-WMF , I have questions on the following two requirements:

In the future, both font sizes should be able to default to standard

Is this something that I can validate through the UI?

We must have the ability to set a different default size for new accounts vs existing accounts

Is this functionality working in beta, or is it planned for the future?

These were both validated by @Jdrewniak in T360098#9693678 and T360098#9693740

For the first one, I don't think there's any way to test this but considering that's current functionality from before this ticket I think we're okay

For the second one, it should be live on beta now (so we'd expect existing user accounts to have default small, and anonymous and new logged-in accounts to have the standard size)

Thanks @SToyofuku-WMF!

@ovasileva, before I update the description with BDD and Test Steps, I wanted to get your approval of the requirement v2 in the description. I wasn't sure how to incorporate the "In the future" requirement bullet, because I wasn't sure how this could be validated. Let me know what you think.

@Edtadros - we can ignore that requirement for right now.

@ovasileva / @Jdlrobson , for testing this in production I will need to know what determines a new user. Is it the number of edits? Length of time since account creation? The creation of a new user in prod is not as easy as in beta and I'd like to use an existing QTE user if possible.

@Edtadros the "new" user is determined by the date the account was created. This date is set in the configuration (below). Currently beta has the date set to April 9th 2024, so anyone registered after that date is considered a new user. This value will change in production based on when we deploy this feature, so I think prod QA should be tied to the eventual deployment task.

// T360098 - change Vector font-size for anons, existing named users or newly created users.
$wgDefaultUserOptions['vector-font-size'] = 1;
$wgConditionalUserOptions['vector-font-size'] = [
	[ 1, [ CUDCOND_AFTER, '20240409000000' ] ],
	[ 0, [ CUDCOND_NAMED ] ],
];

@ovasileva As seen in the screenshots below, all text size were defaulted to "Small", even when it's anonymous and a new user login in En PROD Wiki.

Test Link: https://en.wikipedia.org/w/index.php?title=Polar_bear&vectorclientpreferences=1

This has only be enabled on beta cluster so far. We haven't deployed this to any production wikis.
https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/1017345

@Jdlrobson so can the production testing for the deploy task be skipped? I think my interpretation of the requirement was that the text size would be defaulted, but it may be just that the ability to default is what this task is about.

You can skip. We could also enable this on test.wikipedia.org if @ovasileva wants to verify this now?
