Hi, I'm writing my own SshFile subclasses, and I've hit an issue where Putty's PSFTP client tries to open files for reading, which don't exist.
OpenSSH sftp sends a STAT, gets a NO_SUCH_FILE response then stops. PSFTP seems to send an OPEN regardless of the NO_SUCH_FILE sent in response to STAT. It gets a valid filehandle back, and proceeds to do a bunch of READS. I send back an EOFException, which results in "error while reading: failure" on the client side. But that's not as good as the "file not found" reported by OpenSSH. PSFTP uses V3 OPEN. I see that the version<4 branch in sftpsubsystem.java has nothing that responds with NO_SUCH_FILE, whereas the version>=4 branch can send NO_SUCH_FILE depending on open's flags. Is this fixable, or is it inherently something the V3 protocol can't handle? What should my file class do? -- "There is no way to peace; peace is the way"
