Deprecation warning with MediaWiki 1.35+

[YukinoHayakawa]

Deprecated: Use of Parser::enableOOUI was deprecated in MediaWiki 1.35. [Called from WikiMarkdown::parserHook in
XXX\wiki\extensions\WikiMarkdown\includes\WikiMarkdown.php at line 110] in XXX\wiki\includes\debug\MWDebug.php on line 377

Env:

Installed software
Product Version
MediaWiki 1.38.2
PHP 8.1.6 (apache2handler)
MariaDB 10.4.24-MariaDB
ICU 70.1
Lua 5.1.5
Pygments 2.11.2

In mediawiki's Parser.php the implementation of enableOOUI is as below:

/**
 * Set's up the PHP implementation of OOUI for use in this request
 * and instructs OutputPage to enable OOUI for itself.
 *
 * @since 1.26
 * @deprecated since 1.35, use $parser->getOutput()->setEnableOOUI() instead.
 */
public function enableOOUI() {
	wfDeprecated( __METHOD__, '1.35' );
	OutputPage::setupOOUI();
	$this->mOutput->setEnableOOUI( true );
}

I'm not sure whether copying & pasting the last two lines to the problem site is the right step to take but at least it fixed the thing for me.

This was an intentional usage of the deprecated function. The extension has not been tested with MediaWiki 1.38 as I am mainly interested in supporting LTS releases. I intend to look into this further when the next LTS release comes out (1.39). For now, the deprecation warning shouldn't cause any issues though.

[YukinoHayakawa]

I'm generally ok with using deprecated functions. I was mentioning this mainly due to that the warnings literally populated my pages since I turned on the debug info lol. It's reasonable to wait till the next LTS to fix it IMO.

According to "https://www.mediawiki.org/wiki/MediaWiki_1.39" : "The 1.39.0 stable release came out on 30 November 2022."

I hope you will find a solution.

Hello @kuenzign, is there any plan to fix this now? MediaWiki 1.35 is EoL, and MediaWiki 1.39 and 1.43 are only supported LTS versions.
