Manual talk:ImportDump.php

Problem with --uploads

I'm having absolutly no luck with this. I can import everything perfectly fine, but if i try to add --uploads it fails with the following.

PHP Warning: XMLReader::open(): Unable to open source data in /www/docrootssl/wiki/includes/libs/XmlTypeCheck.php on line 137 PHP Fatal error: Call to undefined method FileRepoStatus::getXml() in /www/docrootssl/wiki/includes/Import.php on line 1602

Wildcard support for filename?

Does this script command support wildcards? For example, is there a syntax that would allow import of *.xml in a given directory? Tcrimsonk (talk) 02:41, 12 July 2016 (UTC)

Import without namespace

Hi, I'm trying to migrate a wiki, but when I execute the ImportDump the articles don't migrate to their correct namespace. All of them go to Main. How can I do now?

Thanks

[EDIT] I've made a mistake in my LocalSettings, but I couldn't find it. Now I could resolve it.

Sorry.

Mention that pages will be assigned to existing users

Mention that pages will be assigned to existing users with the same name, except of course if e.g., "--username-prefix=Imported>" is used. Jidanni (talk) 14:16, 3 January 2020 (UTC)

Many options different nowadays

Looking at the current source file, e.g., --username-prefix now is 'Prefix for interwiki usernames', and lots of other changes, perhaps. Jidanni (talk) 15:07, 3 January 2020 (UTC)

Parallelizing the import

As per request in the Note in this section:

I stumbled across this hint while already importing simplewiki-20220101-pages-articles-multistream.xml which was taking quite some time. So I opened up to 8 terminals and ran additional instances of importDump.php using the --skipTo option with steps of 25000. Once an instance catches up to its successor, the script speeds up considerably, at which point I terminated the instance.

The slowdown in the course of time mentioned elsewhere still happens (any clues on why this happens?), so I did the above iteratively: when all except one of the initial instances were done (i.e., terminated by Ctrl-C), I partitioned the rest that was left to process with smaller steps for --skipTo.

In the end, Special:Statistics shows 357866 Pages (but no Content pages?). Displaying random pages indicates that the import succeeded.

Second round using the newer simplewiki-20221120-pages-articles-multistream.xml indicates that terminating/restarting instances is not required. Started eight instances with steps of 50000 for the --skipTo option and just let them run. Sorry, forgot to time the calls. After the import, Special:Statistics shows 420701 Pages.

How is this run using Run.php

I get warning messages saying this, and ExportDump.php should not be directly run, but instead should be used in conjunction with Run.php. How exactly is that done? I've had no luck! --Trig12 (talk) 01:53, 28 January 2024 (UTC)

The easiest way is from the /var/www/html/mediawiki folder run
