Possibly deploy blocker? Seems like the core change I made had some unexpected side effects.

IMHO, a big change like this should have been QAed first before deploying to production wikis.

It was QAed but we're only human :) There are lots of extensions and different settings, different user rights and different user preferences on different wikis and different users. It would take us a week to manually test all the combinations. Sadly we do rely on bug reports like this a lot of the time (so thanks for catching!)

The patrol link is particularly hard to QA and right now I'm struggling to find an example for testing on https://en.wikipedia.beta.wmflabs.org/ can you help me find one? I think I can see what happened here.

Steps to reproduce:

• Go to https://commons.m.wikimedia.beta.wmflabs.org/wiki/Test on Commons beta cluster since patrolling is enabled there
• Make an edit as an IP.
• compare the both mobile and desktop diff. eg. https://commons.m.wikimedia.beta.wmflabs.org/wiki/Special:MobileDiff/216260 with https://commons.wikimedia.beta.wmflabs.org/w/index.php?title=Test&diff=216260&diffmode=source

I have granted you patrol rights on beta Commons so you should be able to see the patrol link/button.

4. Possible diff style issues

I am noticing some style issues. Background colors (red and green) extend to the whole line (covers up the spaces without any content). Is this intended or a bug?

Looks fine to me but I defer to @alexhollender if there is a styling problem here.

Sorry for not providing another screenshot to compare. Try to compare

@Jdlrobson looks like all of the bugs listed here has been fixed except the design issue which will be reviewed by Alex. But I am unsure if it's OK to change the patrol button to a link. The link is smaller than the button, it's located under the diff, and it will probably go unnoticed if the diff is long. Also I don't see the point of scrolling all the way to the bottom just to mark a revision as patrolled. It would probably better if the patrol link is displayed at the top, just like the desktop version. Thoughts?

@Ammarpad I was wondering if you found any bugs. If you have, now might be the best time to fix them as part of this task.

QA

Device: Android 7.0 Chrome 79.0
Screen size: 600 x 1200 px
Status: PASS

Bug 1. Mark as patrolled link isn't being shown in this new Special:MobileDiff

• Ensure that a "mark as patrolled" link appears at the bottom of the diff. ✅ OK.

Bug 2. Buttons to switch to a VisualDiff doesn't work

• Ensure that the buttons to switch to visual and wikitext diffs doesn't appear in mobile diff if VisualDiff beta feature is enabled. ✅ OK.

Bug 3. Mobile diff width is broken

• Visited https://commons.m.wikimedia.org/wiki/Special:MobileDiff/386306397
• Ensure the width actually fits to the screen. ✅ Fixed.

Before	After

Moving to design review for Alex. QA is passed.

@Jdlrobson another regression. Same as T117279#5817692

Steps to reproduce

• Visit https://commons.m.wikimedia.org/wiki/Special:MobileDiff/388741403 or any structured data diff

Result

• The diff is still shown side by side instead of showing an inline diff.

@Jdlrobson @Masumrezarock100 I am having trouble reviewing these fixes.

1. Mark as patrolled link — I am unable to see the patrolled link but this is maybe a configuration issue?
2. Buttons to switch to a VisualDiff — I am unable to enable this beta feature, I get an error: "The Wikimedia Commons database is temporarily in read-only mode for the following reason: The database is read-only until replication lag decreases.").
3. Mobile diff width — the width seems to be okay, however words are breaking in a way that seems unexpected?

Diff in https://commons.m.wikimedia.org/wiki/Special:MobileDiff/386331930

To me it seems easier to read when the background color covers the entire paragraph, rather than leaving white gaps between each line.

The patch above should take care of this.

I don't think it's a site configuration issue. The patrol right is available to patrollers, admins, and image reviewers on Commons. I assume https://commons.m.wikimedia.beta.wmflabs.org/wiki/Special:Contributions/Alex_Hollender_(admn) is your beta cluster account? I have granted you the patroller flag on beta Commons. You should be able see patrol links from your account now if you view an unpatrolled edit. Follow the steps in T242310#5790108.

You will likely be able to enable the beta feature once the lag decreases. Nothing abnormal.

@nray @phuedx to test this you need to enable wikidiff2. Right now when you visit Special:MobileDiff you are seeing the 3rd party version of the page rather than the one we use in production.

The 3rd party version is removed in https://gerrit.wikimedia.org/r/556811 (T240622) - and one of the motivations for doing this was that we should be testing the production version locally and not maintaining unnecessary code (note you can confirm the absence of wikidiff2 by checking out that patch as well - you will see the unified view). I scheduled this patch for prioritisation/discussion as we can remove this now at our leisure.

For testing this patch and further diff related patches please install wikidiff2 (https://www.mediawiki.org/wiki/Wikidiff2) or alternatively mock it using the following code in LocalSettings.php

function wikidiff2_do_diff( $a, $b, $c ) {
	return '<tr>
	<td colspan="2" class="diff-lineno"><!--LINE 1--></td>
	<td colspan="2" class="diff-lineno"><!--LINE 1--></td>

@Jdlrobson: Can this be tested on the Beta Cluster?

@Jdlrobson I am afraid the 2nd problem's OA steps are outdated. The patches in T242351 got merged, so I am now seeing the buttons (it wasn't used to, as I confirmed above) if I have enabled the beta feature.

@Jdlrobson if I'm reading this correctly I need IP permissions. I'm using Edtadros-beta1 as my test user.

I am not sure what you meant by IP permissions. By making edits as a IP, I meant that you needed to make edits while you are logged out/using incognito mode. The only permission you need at the moment is "patrol" rights which let's one mark edits as patrolled. You won't be able to see the mark as patrolled link without this permission. And done. You should now be able to see the patrol links on beta Commons.

@Masumrezarock100 Thanks for clarifying what IP meant, and the patrol rights.
