Hi everyone, I am trying to restore the revision table from Wikipedia dumps. I understand that the file that I need is probably enwiki-XX-pages- logging.xml.gz I've downloaded the file and I am using the 1.16 version of mwdumper from https://integration.wikimedia.org/ci/job/MWDumper-package/org.wikimedia$mwd… When I execute the following I get this error: java -server -jar mwdumper.jar --format=sql:1.5 enwiki-20130503-pages-logging.xml.gz | gzip -vc > enwiki-latest-pages-articles.sql.gz Exception in thread "main" java.lang.IllegalArgumentException: Unexpected <id> outside a <page>, <revision>, or <contributor> at org.mediawiki.importer.XmlDumpReader.readId(XmlDumpReader.java:329) at org.mediawiki.importer.XmlDumpReader.endElement(XmlDumpReader.java:204) at org.apache.xerces.parsers.AbstractSAXParser.endElement(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanEndElement(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) at javax.xml.parsers.SAXParser.parse(SAXParser.java:392) at javax.xml.parsers.SAXParser.parse(SAXParser.java:195) at org.mediawiki.importer.XmlDumpReader.readDump(XmlDumpReader.java:88) at org.mediawiki.dumper.Dumper.main(Dumper.java:142) 0.0% Mwdumper works well with other 7z xml files but not for this one. I tried a couple of different xml page-logging files and even from a different language wikipedias. Anyone knows what this error is and why it occurs on this specific file? PS: I've also tried to build mwdumper: git clone https://gerrit.wikimedia.org/r/p/mediawiki/tools/mwdumper.git mwdumper However I couldn't use make or ant since there was not build.xml or makefile in the git. I appreciate any help you can give me with this.

Actually you want one of the xml files with page content, either enwiki-20130503-pages-articles.xml.bz2 , enwiki-20130503-pages-meta-current.xml.bz2 or the various meta-history bz2 or 7z files. This depends on whether you want the current revision for the articles and related namespace pages only, the current revision for all pages, or all revisions for all pages. Mwdumper will generate sql from these files to populate the revision, text and page tables, all in one output file. All of these will be written in one file intermingled, so you'll want to grab just the sql statements pertaining to the revision table if that's all you want to recreate. I don't know if it works well with the latest dumps. The pages-logging xml file could conceivably be used for repopulating the logging table and part of the user table (poorly); I imagine most folks use it for research purposes rather than import data.

You can backtrack a couple revisions in git to get one that's buildable. I'm cc-ing Chad on this since he knows about the build setup. Ariel

That would be because we swapped out Ant in favor of Maven a little while back. `mvn package` should work just fine. -Chad

Great that should work just fine! The pages-meta-history are the files that I want although I modified the text blob columns to varchar since I really don't need this data to be restored and they tend to be the largest. Thank you both for your help! Michael On Fri, May 17, 2013 at 11:57 AM, Chad <innocentkiller(a)gmail.com> wrote:

great! at least we know what's causing it. I've seen the thread about xerces before but it was too old so I thought there is probably no relation.

Update on the matter. I've edited pom.xml and changed xerces version which was set to 2.7.1 to 2.9.1, 2.11.0, 2.8.0 and other versions. The out of bound error becomes different on later versions but still the error persists. Also, I tried to use mwdumper with an older version of wikipedia dump: 20130102. The error still appears on the first file this time: enwiki-20130102-pages-meta-history1.xml-p000000010p000002070.7z Should I report a new bug on bugzilla for mwdumper?

If you can stomach it I would report it upstream, linking to the earlier version of the bug they had with a proposed patch etc. I can give them a test file consisting of the one page with all its revisions, "only" 170 mb uncompressed :-D It's fine to open a report locally too in mwdumper and link the upstream report.

If you mean importDump.php, I strongly recommend against it. For a large wiki it's going to take forever, if indeed it completes at all. I would suggest removing the page that causes the problem and using mwdumper on the rest, then using importDump.php on the one page and its revisions only. There are a couple other experimental tools yu could try but they are indeed experimental, see http://meta.wikimedia.org/wiki/Data_dumps/Tools_for_importing Ariel
