With an upload-id-marker the lister ranges over Uploads[startIndex:],
but passed the index of that subslice to hasMoreAfter, which indexes
the full list. A page that ended on the last remaining upload was still
reported as truncated, with next markers pointing at that upload, so a
client had to make one more request to get an empty page.
Iterate over the full list from startIndex, so hasMoreAfter gets the
real position of the next upload.
The posix and azure backends dropped every upload with a key equal to
the key-marker before handing the list to the lister, which then looked
for the upload-id-marker under the next key. An upload-id-marker that
belongs to the key-marker could never be found, so the request failed
with "Invalid uploadId marker", including when a client paged with the
NextKeyMarker and NextUploadIdMarker the gateway returned.
Keep the uploads of the key-marker itself when an upload-id-marker is
set, so the listing continues right after the given upload, as S3 does.
Enable the REST test that covers it.
Fixes#2149
An upload-id-marker sent without a key-marker is ignored for the
listing, but the gateway still echoed it back in UploadIdMarker. S3
discards the parameter in that case and returns an empty
UploadIdMarker.
Clear the marker in the controller when no key-marker is given, so
every backend gets the same input and the response no longer reports
a marker that had no effect.
Fixes#2150
NextKeyMarker and NextUploadIdMarker were only set for a truncated
listing, so a ListMultipartUploads response that fit in one page
returned them empty. S3 still sets them to the key and upload ID of
the last upload in the response.
Fill both markers from the last listed upload when the listing is not
truncated, including the case where the page ends exactly at
max-uploads. A page of common prefixes only keeps them empty, as
before. Enable the REST test that covers it.
Fixes#2144
A bucket GET with both the uploads and uploadId query parameters was
routed to ListMultipartUploads and answered with the upload listing.
S3 rejects the combination with 400 InvalidArgument, "Conflicting query
string parameters: uploadId, uploads".
Add an error route for the combination ahead of ListMultipartUploads,
the way the object level '?uploads' request is rejected, and enable
the REST test that covers it.
Fixes#2155
