On outdated wikis running MediaWiki 1.21 to 1.25, it will change the format in which the continuation data is returned. In any case, when you're manually adding it you should use an empty value rather than "||". Note the values of all continuation parameters, whether old or new format, should be considered as opaque tokens by clients (even though they usually have obvious structure). The API may change the format of these continuation tokens at any time without warning, and this will not be considered a breaking change. The old format for continuation returns data in a query-continue node to be combined with the previous requests' parameters. When using generators or multiple query submodules, the client has to do some non-obvious processing of that continuation data to avoid missing data or looping. See https://www.mediawiki.org/wiki/API:Raw_query_continue for details. In 1.21, a new, easier to use format was introduced, enabled by passing an empty "continue" parameter when making the initial query. In this mode the API handles the tricky parts of generators and multiple query submodules for you, all you have to do is combine everything under the returned "continue" node with the original request's parameters. This was made the default in MediaWiki 1.26. See https://www.mediawiki.org/wiki/API:Query#Continuing_queries for details. New clients should use this new format since it's much harder to handle it incorrectly. The "continue=||" is part of the new format's handling of the tricky bits of generators and multiple query modules. -- Brad Jorsch (Anomie) Senior Software Engineer Wikimedia Foundation _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
