dumpHTML is an extension for generating a simple HTML dump, including images and media files, of a MediaWiki installation. MediaWiki versions before 1.12.0 used the maintenance script dumpHTML.php instead.

Parameters[edit | edit source]

dumpHTML does not function like a normal extension; you must run it from the command line.

Option/Parameter Description
-d <dest> destination directory
-s <start> start ID
-e <end> end ID
-k <skin> skin to use (defaults to offline)
--no-overwrite skip existing HTML files
--checkpoint <file> use a checkpoint file to allow restarting of interrupted dumps
--slice <n/m> split the job into m segments and do the n'th one
--images only do image description pages
--shared-desc only do shared (commons) image description pages
--no-shared-desc don't do shared image description pages
--categories only do category pages
--redirects only do redirects
--special only do miscellaneous stuff
--interlang allow interlanguage links
--image-snapshot copy all images used to the destination directory
--compress generate compressed version of the html pages
--udp-profile <N> profile 1/N rendering operations using ProfilerSimpleUDP
--munge-title <HOW> available munging algorithms: none, md5, windows

Example to create a complete snapshot including image and media files and image thumbnail files in directory wikidump (LINUX)

/usr/bin/php /srv/www/mediawiki/extensions/DumpHTML/dumpHTML.php -d /srv/www/mediawiki/wikidump -k monobook --image-snapshot

Known issues[edit | edit source]

Warning! This extension is not properly maintained at the moment! You may encounter a number of issues. Any help fixing these (especially by sending patches to Gerrit) is greatly appreciated!

Filename problems solved by a modified version of DumpHTML[edit | edit source]

  • fixed via (--munge-title <HOW> available munging algorithms: none, md5, windows) in r115629

If you intend to use the wikidump on a CD/DVD or on a Windows filesystem, and if the wiki pages or files had non-ASCII characters (which is likely) then you probably need to change the link references, the directories, and filenames from UTF-8 to your Windows character encoding (for example to codepage 1252 for Western-European systems), but browsers may still have difficulties accessing the files.

Bugzilla 8147 "Filenames in the HTML static dump" has a patch for DumpHTML.inc that converts article, image, thumbnail image, and media filenames to their MD5-hashed version, which avoids character encoding problems on different operation systems.

Skin hacking[edit | edit source]

If you modified your skin (e.g. monobook) then this script will likely fail. Upgrade/update your mediawiki installation and replace any "hacked" skins, then re-try.

Extensions compatibility[edit | edit source]

For the same reason, some extensions modifying output aren't compatible with DumpHTML, like Extension:SyntaxHighlight_GeSHi.

If you use InstantCommons[edit | edit source]

If you use your dump on a custom MediaWiki install using InstantCommons, the script will consider your images files are in the images/wikimediacommons folder of the target directory.

Thus, if you encounter a message as:

Warning: file_put_contents(/tmp/wiki/images/wikimediacommons/7/75/Live_studio_op_de_Mi_Amigo_kleine.jpg):
failed to open stream: No such file or directory in [...]/w/extensions/DumpHTML/dumpHTML.inc on line 1377

You have to download http://upload.wikimedia.org/wikipedia/commons/7/75/Live_studio_op_de_Mi_Amigo_kleine.jpg to /tmp/yourdump/images/wikimediacommons/7/75/Live_studio_op_de_Mi_Amigo_kleine.jpg and restart the dump operation.

Static Wikipedia[edit | edit source]

See http://dumps.wikimedia.org/ and for example http://dumps.wikimedia.org/other/static_html_dumps/ for static snapshot examples. The last HTML dumps there were generated in 2008 (bug 15017).
