Steps to replicate:
- Perform the API query https://en.wikipedia.org/w/api.php?action=query&errorformat=html&prop=revisions&rvslots=main&titles=Obama&formatversion=2&rvprop=content&rvlimit=600
- For users with apihighlimits change rvlimit to 6000 instead to replicate the bug.
Expected output:
- A single outofrange warning with text "The value \"600\" for parameter \"rvlimit\" must be between 1 and 50."
Actual output:
- Response contains 2 outofrange warnings:
"warnings": [
{
"code": "outofrange",
"text": "The value \"600\" for parameter \"rvlimit\" must be between 1 and 500.",
"data": {
"min": 1,
"curmax": 500,
"max": 500,
"highmax": 5000
},
"module": "query+revisions"
},
{
"code": "outofrange",
"text": "The value \"500\" for parameter \"rvlimit\" must be between 1 and 50.",
"data": {
"min": 1,
"curmax": 50,
"max": 50,
"highmax": 500
},
"module": "query+revisions"
}
]With the default legacy errorformat, there is a single warning with confusing text instead:
"warnings": "The value \"600\" for parameter \"rvlimit\" must be between 1 and 500.\nThe value \"500\" for parameter \"rvlimit\" must be between 1 and 50."
This appears to be because ApiQueryRevisions has a limit of 500, but it's reduced to 50 when rvprop=content is enabled.
