Hello everyone! I've encountered a bug using VisualEditor with Lingo installed. What happened is it wouldn't let me edit using VisualEditor throwing a following exception:

I'm running MediaWiki 1.41.1 and Lingo 3.1.1. As a temporal dirty workaround I added some lines in Lingo/src/LingoParser.php that check whether Parser::$mOutput was initialized and it seems to be working:

	/**
	 * @param Parser $parser
	 * @return bool
	 */
	private function shouldParse( $parser ) {
		global $wgexLingoUseNamespaces;

		if ( !( $parser instanceof Parser || $parser instanceof StubObject ) ) {
			return false;
		}

		$reflectionClass = new \ReflectionClass(Parser::class);

		if ( !$reflectionClass->getProperty( 'mOutput' )->isInitialized( $parser ) ) {
			return false;
		}
‎

Is there any solution to this? Thanks in advance!

Correction - this does not actually fix the issue. It DOES allow VisualEditor to open and work but the the site becomes unstable.

Further investigation revealed that (without the changes) VisualEditor opens up when you are CREATING a new page but pops an error when attempting to edit an existing page.

As a work-around, I simply open a new page and create my changes if needed then switch to Edit Source and copy pasta!

Elcapitan68 (talkcontribs)

I am unsure why do you use Lingo 3.1.1 (this tag was released in 2019).

If you use composer as required https://github.com/wikimedia/mediawiki-extensions-Lingo, it should end up with installing Lingo 3.2.

If you can't use composer for some reason, we suggest installing branch REL1_39 via git. It is targeted at work with MW 1.39 but can work with 1.41, please test.

I updated the direct download link on the extension page so that now it points to the version 3.2.0.

GobleStL (talkcontribs)

Sorry. That is a typo I missed. I am on 3.2.1 and using Composer.

SG

Elcapitan68 (talkcontribs)

I confirm the described behavior in my test environment:

  • MediaWiki 1.41
  • PHP 8.1
  • Lingo 3.2.0

Perhaps it is due to the recent changes in the MediaWiki core.

Lingo with VisualEditor in MediaWiki 1.39

In the recommended environment:

  • MediaWiki 1.39
  • PHP 8.1
  • Lingo 3.2.0

everything works correctly.

Joe Beaudoin Jr. Redux (talkcontribs)

This has not been fixed in MW 1.41 and Lingo 3.2.1. This is still an open issue for REL1_41, which I am able to unfortunately replicate.

Elcapitan68 (talkcontribs)

Thank you for testing. I confirmed the failure for MW 1.41 in the above comment.

As long as the extension compatibility policy is LTS (key: ltsrel), we expect it to work with MW 1.39 and 1.43. Tasks can be added to Phabricator issue tracker about the issues in the non-LTS versions.

MediaViewer also has issues and has been disabled so direct viewing of images is fine. But with Lingo I get this:

Everything else seems good.

This is a fresh build with the aforementioned versions.

Any ideas?

Elcapitan68 (talkcontribs)

Thank you for your report, we're working on 1.39 compatibility and the issue should have an update soon.

GobleStL (talkcontribs)

THANK YOU!

X-Savitar (talkcontribs)

The lastest patch has been merged, can you test it with the patch merged (master) and let me know if you still face this issue?

GobleStL (talkcontribs)

THANKS! I will check as soon as I can.

GobleStL (talkcontribs)

This works for me. No issues.

X-Savitar (talkcontribs)

Nice! Thanks for reporting the issue. I'll go ahead and resolve this topic now.

Can't confirm. Lingo 3.2.0 installed as explained in the Composer section of the extension page, produces tooltips correctly with the default settings.

Elcapitan68 (talkcontribs)

Please note that the next official release of Lingo will be for the next MediaWiki LTS version in accordance with Lingo compatibility policy (LTSrel).

Due to the latest changes in the core, I changed the requirements on the extension page.

Use of Hooks deprecated?

GobleStL (talkcontribs)

I have been searching and cannot figure this one out. Lingo is operational but when I run update.php I get this:

PHP Deprecated:  Use of Hooks::register was deprecated in MediaWiki 1.35. [Called from Lingo\BasicBackend::registerHooks in /var/www/mediawiki/extensions/Lingo/src/BasicBackend.php at line 58] in /var/www/mediawiki/includes/debug/MWDebug.php on line 386

Any idea?

Cavila (talkcontribs)

It is just a PHP warning that gets thrown if your current version of MediaWiki is v1.35 or over but your version of Lingo lingers behind. Your best bet is to upgrade Lingo.

GobleStL (talkcontribs)

I am at the latest.

GobleStL (talkcontribs)

Tried 3.2.1 also...

Cavila (talkcontribs)
Elcapitan68 (talkcontribs)

It is fixed in REL1_39 (LTS) according to the extension compatibility policy (ltsrel): https://github.com/wikimedia/mediawiki-extensions-Lingo/blob/c88549b25caa48012b915c150115c7100ded82be/src/BasicBackend.php#L56C1-L60C3

If you are on MW 1.39, please checkout REL1_39 branch, rather than a tag.

If you are running MW < 1.39, just ignore the message, as mentioned by @Cavila, it is just a deprecation warning and will go away with the upgrade to 1.39.

As for MW 1.35, it went end-of-life on December 21, 2023.

GobleStL (talkcontribs)

It actually only pops this error when I use VisualEditor. I disable Lingo when I need to use that extension and then have no issues.

Elcapitan68 (talkcontribs)

@GobleStL Please, make sure that you have PHP error reporting off in your LocalSettings.php and repeat testing. In case of failure, please share your current MW version number + PHP version, so that we could try to reproduce the error. A link to your LocalSettings.php will also be very helpful (just wipe the sensitive info out).

GobleStL (talkcontribs)

With error reporting on: "[58a6c0d657e09eaaaf0dc77c] Exception caught: Typed property Parser::$mOutput must not be accessed before initialization"

With error reporting off: "[addf778021d79e091496ce38] Caught exception of type Error"

This only pops up when I attempt to use VisualEditor. Lingo works just fine.

If I disable Lingo extension, VisualEditor opens without an error. I believe it is related to https://phabricator.wikimedia.org/T357686

In troubleshooting this I upgraded everything. I even started using dev branches. (The error started when on stable branch). Currently I am:

We only support LTS branches of MediaWiki. You can try the REL1_39 branch's code and it might work with 1.41. Probably unrelated, running MediaWiki with version 8.3 might cause issues.

Thank you. I realize this. This is why I just disable the extension when I want to use VisualEditor.

MW 1.39, php 8.1, Lingo extension REL1_39 and I'm getting:

Warning: Undefined global variable $wgParser in/var/www/html/extensions/Lingo/src/Lingo.php on line53

Hi @Allanext2, please let me know what installation method did you use (cloning Git repo, composer or something else)?

Allanext2 (talkcontribs)

Hi @Elcapitan68,

I have it installed with a git submodule from the github repo, below the entry in .gitmodules:

[submodule "data/extensions/Lingo"]

path = data/extensions/Lingo

url = https://github.com/wikimedia/mediawiki-extensions-Lingo.git

branch = REL1_39

I then do:

git submodule init

git submodule update

git submodule foreach -q 'branch="$(git config -f $toplevel/.gitmodules submodule.$name.branch)"; echo "Extension $name:"; git switch $branch'

Thank you !

Please check paths, REL1_39 of Lingo seems to be free of wgParser:

See here.

Is there a chance that you mount an outdated branch some way?

What happens if you checkout the tag?

cd extensions/Lingo

git checkout 3.2.0
Allanext2 (talkcontribs)

@Elcapitan68 You're right the REL1_39 branch in clean of wgParser.

The issue is that when Semantic Glossary is installed (dev-master branch) with `composer update --no-dev` it requires the dependency Lingo 3.1.1 which overrides files

How to use a Project namespace Terminology page?

Summary by SlyAceZeta

Sorry for the late reply! Indeed, setting $wgexLingoPage = 'Project:Terminology'; does the trick :)

SlyAceZeta (talkcontribs)

I'm trying to use Project:Terminology as the terminology page for the extension across an entire wiki, but the extension doesn't seem to recognize that page when I set it in MediaWiki:Lingo-terminologypagename, using either "Project:Terminology" or "Wiki Name:Terminology".

@SlyCooperFan1, did you have a chance to try setting $wgexLingoPage? Did it help?

Very strange: TOC showing at start of some pages when Lingo is enabled

The bug report is created on Phabricator https://phabricator.wikimedia.org/T348465. In the meanwhile, a CSS workaround is suggested.

I am using the vector 2022 skin and recently installed the Lingo extension, love it but I have this very strange problem, when I have Lingo enabled, I found that the TOC is displayed at the beginning of only some pages.. if I switch to the old vector (2010) skin, the TOC displays at the beginning of all pages (which is expected). Has anyone seen this issue or any idea where could be the problem? Below are the versions:

Product Version
MediaWiki 1.39.2
PHP 8.1.13 (fpm-fcgi)
MariaDB 10.6.11-MariaDB
ICU 67.1
Lua 5.1.5
Pygments 2.11.2
Elcapitan68 (talkcontribs)

Hi, @Paulxu20 Please, provide a link to a live page with the described TOC behavior or to a screenshot. Also, make sure your expectations about all pages are correct: by design, a table of contents is automatically generated on a page when more than three section headings are used (Manual:Table of contents)

Paulxu20 (talkcontribs)

Hi @Elcapitan68, thanks for the reply! Here is an example: https://papals.org/index.php?title=Test3, you can see on this page the TOC is appearing both at beginning of the page, as well as on the sidebar. And you are right, but I am under the impression that if the skin is vector 2010, the toc only appears at the beginning of the page, but if the skin is vector 2020, the toc only appears on the sidebar, no?

What is happening now is that the toc appears on both the beginning of the page and the sidebar when the skin is vector 2020, I am actually OK with this, but the problem is that it is not consistent, on some page it appears on both places, on some page it only appears on sidebar.

Pretty sure it has something to do with Lingo, because if you look at this test page https://papals.org/index.php?title=Test4, notice that it does not have the word "GU" (which is in the glossary list) on the page, and the toc only appears in sidebar. But on https://papals.org/index.php?title=Test3, it does have "GU" at beginning of the page, which triggered Lingo to render the tooltip, and the toc appears on both places.

Elcapitan68 (talkcontribs)

@Paulxu20, we should probably call it "vector-2022"? Indeed, it looks strange. The page Reading/Web/Desktop Improvements/Features/Table of contents describes the concept of the new TOC, saying that "We intentionally do not add the old table of contents to the article in addition to the new sidebar location". Please, let me know if you use caching (varnish / redis / cloudflare / file cache / etc.).

Paulxu20 (talkcontribs)

Hi @Elcapitan68, for caching APCu is used. In the LocalSettings.php it is set like this: $wgMainCacheType = CACHE_ACCEL;

I am not sure if this is the best caching option performance wise, but it has been working ok to me.

Elcapitan68 (talkcontribs)

@Paulxu20 I see. It looks like a side effect of the way src/LingoParser.php works. It re-renders the page injecting its elements and is not aware about the latest Vector specifics. I will create a ticket for investigating and fixing this.

In the meanwhile I suggest hiding the in-page TOC with CSS on MediaWiki:Vector-2022.css, like this:

#mw-content-text #toc {

  display: none;

}

Addition of new terms or making changes in existing is not reflecting

Possibly a caching issue

Boopalag (talkcontribs)

Whenever i tried to add new terms or making changes in existing lingo terms, those changes are not reflecting on my media wiki pages but i could see the terms i added is reflecting on my terminology page. Can anyone help on this issue ?

X-Savitar (talkcontribs)

@Boopalag, can you share screen shorts of expected and actual behavior and the version of Lingo you're running including the version of MediaWiki?

Boopalag (talkcontribs)

Hi X-Savitar, Thanks a lot for response, Now the issue is little different.

Actually we are able to see the tooltip but there is a delay for the tooltip to be visible after a new Glossary term is added (approx 4-7 days delay). Sometimes its reflecting within a day and sometimes after a week (there is no uniform pattern).

Any suggestions to make the tooltip visible immediately after a new term is added?

Mediawiki - 1.35.3 with the Lingo version - 3.1.1 (8ae42ff)

My previous thread on Support desk: Topic:Xhcx9i52jjtxukye

While operating "Special:Movepage" on my wiki, MediaWiki reports this error output. The version of Lingo is 3.2.0. After disabling Lingo from the LocalSettings.php, the error output disappeared. So I'm pretty sure it's Lingo's bug.

I wonder if it's related to PHP 8. We'll see if we can reproduce this.

X-Savitar (talkcontribs)

@WrOffi, I've not been able to reproduce this. Does the page you're moving have translations?

Can you share with me some steps on reproducing?

I've tried moving a regular page without translations and it works well. Looking at the backtrace, I see something related to the translate extension so I want to be sure because this could be affecting translation pages with Lingo.

Bawolff (talkcontribs)

Possibly related to Extension:SpamBlacklist (There was a somewhat similar issue with a different extension that only showed up when SpamBlacklist was installed).

WrOffi (talkcontribs)

I've tried to disable SpamBlacklist and reactivate Lingo, but it shows up the error again.

After disabling Lingo, everything works fine

X-Savitar (talkcontribs)

@WrOffi, my suspicion is that this could be related to the Translate extension together with Lingo. When I have Lingo in isolation, it works fine but seems on translation pages, this causes the issue (have not yet reproduced it since I don't have the extension locally).

If you disable the Translate extension, does the "move" action work?

Tosfos (talkcontribs)

I think the best way to test this is to disable all other extensions and see if the issue still exists. If not, enable extensions one at a time until you find the culprit.

Return to "Lingo" page.
