OK. Findings:
1. This server sends longname as `-rw-rw-rw 1 root root 1944
Apr 24 14:58 demo.csv` (just before offset 288)
2. This is then followed by flags 0x00_00_00_0F: we have size, uid/gid,
permissions, and access and modification time.
- Size is 0x00_00_00_00_00_00_07_98, i.e. 1944 bytes
- UID = 0x00_00_00_00, GID = 0x00_00_00_00
- Permissions = 0x00_00_01_B6 (438, rw-rw-rw-)
- Access and modification times (both are equal, two 4-byte unsigned
ints, seconds since Unix Epoch)
So far, so bad. The server indeed does not send the "file type" flags in
"permissions". And moreover, its "longname" looks strange. I would have
expected it to start with "-rw-rw-rw-", not with "-rw-rw-rw ".
WinSCP indeed parses "longname". It assumes that the first character of the
longname gives the item type: '-' for a regular file, 'l' for a symbolic link,
and 'd' for a directory (case insensitive).
I suppose we should do so, too, at least if it's SFTP V3 and the permissions
don't give the file type.
