As an Action API user, I expect that whenever the response is truncated, I can follow continuation to get the remaining data with additional requests.
List of steps to reproduce (step by step, including full links if applicable):
- Craft an API request that, without meta=tokens, just barely fits within the $wgAPIMaxResultSize.
- Add meta=tokens, optionally with a type.
This is very unlikely to happen by accident, but it can be done manually: example URL
What happens?:
- There is a warning that the result was truncated because it would otherwise be larger than the configured limit (12 MiB on Wikimedia wikis, “temporary” since at least 2012). This is expected.
- The tokens are not included in the response, because ApiQuery::execute() processes prop modules, then list modules, then meta modules; we used prop modules to “fill up” the response, so by the time the API reaches the tokens module, it won’t fit anymore. This is fine (though I could also imagine the API processing meta modules first).
- The response has no continue member. This is not fine: there is no way to get tokens based on this response, you don’t have anywhere to go from it.
What should have happened instead?:
There should be a continue member in the response, which when added to a subsequent request should result in a response without the data that was already returned, and with tokens in it. meta=siteinfo does it right, for example: initial URL (returns "continue": { "siprop": "general", "continue": "-||revisions" }), continued URL.
