Description

I am running importDump.php to import Wiktionary into a local MediaWiki instance (XAMPP on Windows 10).

This error occurs when the importer reaches the attached example.xml page:

C:\xampp\htdocs\mediawiki-134git\maintenance>php importDump.php --conf ../LocalSettings.php --username-prefix="" C:\example.xml

@828bmartin: I don't see how this is related to Scribunto?

828bmartin added a comment.Feb 1 2020, 10:35 PM

@Aklapper I only tagged it as Scribunto because that's the Module page that causes the import to fail.

I get the same error while importing or when i just paste the content from the failed pages from Wikipedia into my 1.35.0.

The actual error was:

MySQL server has gone away (127.0.0.1)

in the insert into text due to packet size limit being to log in mysql for this much content on a single page. So i set it to 16M in my.ini and it worked afterwards. Manually and for the import

max_allowed_packet=16M
