Steps to replicate the issue (include links if applicable):
Invoke the following MediaWiki API request [ API Sandbox ]
https://commons.wikimedia.org/w/api.php ?action=query &format=json &prop=imageinfo &titles=File%3AHarku%20m%C3%B5isa%20park.JPG &formatversion=2 &iilimit=1
What happens?:
You will receive the following response
{
"continue": {
"iistart": "2013-06-05T14:45:37Z", // <-- ???
"continue": "||"
},
"query": {
"pages": [
{
"pageid": 26499141,
"ns": 6,
"title": "File:Harku mõisa park.JPG",
"imagerepository": "local",
"imageinfo": [
{
"timestamp": "2013-06-05T14:45:37Z",
"user": "Sumistaja"
}
]
}
]
}
}Note how the $.continue.iistart is using the exactly same value as $.query.pages.[0].imageinfo.[0].timestamp.
If you feed the continuation parameters back to the request URL, you will basically receive exactly the same JSON response.
What should have happened instead?:
I expect $.continue.iistart to be something different that won't lead me to a dead continuation loop.
Actually, if I increase iilimit a bit, I will be able to guess why such weird continuation token gets returned. Invoke the following MediaWiki API request [ API Sandbox ]
https://commons.wikimedia.org/w/api.php ?action=query &format=json &prop=imageinfo &titles=File%3AHarku%20m%C3%B5isa%20park.JPG &formatversion=2 &iilimit=10
I will receive the following response
{
"batchcomplete": true,
"query": {
"pages": [
{
"pageid": 26499141,
"ns": 6,
"title": "File:Harku mõisa park.JPG",
"imagerepository": "local",
"imageinfo": [
{
"timestamp": "2013-06-05T14:45:37Z",
"user": "Sumistaja"
},
{
"filemissing": true // <-- [A]
}
]
}
]
}
}I'm not sure whether this is related, but it seems the timestamp of missing file "[A]" (indicated by filemissing) has been removed since MW 1.34.
While I understand the reason behind the removal of the timestamp property that hasn't been populated with a meaningful value, probably you can consider using something different for continuation parameter, so at least we can move on.
