Looks like this should be `filesize` instead of `cnt` on this line: https://github.com/xrootd/xrootd/blob/7407ea85efba9c116e4d42156fc835f8c51b569d/src/XrdHttp/XrdHttpReq.cc#L1928 I'm working on a pure-python backend for uproot based on the HTTP api (so it doesn't have to have the xrootd C++ API), so there's no users yet. As a workaround, I can start with a HEAD call to get the file length. -- You are receiving this because you are subscribed to this thread.
