Re: session.FileExists hangs when no file but returns 'true' when when there is as expected.

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, set Session.SessionLogPath. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

Looks like this isn't isolated issue (https://winscp.net/forum/viewtopic.php?t=15326) with FileExists hanging when returning an error condition. This works on another of our SFTP servers. So I will post up the differences of the two shortly once our admin sends me a summary.

session.FileExists hangs when no file but returns 'true' when when there is as expected.

Hi,

I'm using VB .net within Visual Studio but the FileExists hangs and does nothing when no file exist on remote SFTP server. ie it doesn't receive a 'false'. PutFiles and GetFiles seem fine. 

  

          

If session.FileExists(toFile) Then                                                                        

    session.RemoveFiles(toFile)

End If


Also MoveFiles also hangs if the file moved to exists. Is there a overwrite for this? Or at least return an error code so it can be handled.

And RemoveFiles hangs if no file exists to remove.


Just used this sites exact sample as provided and this hanged when the GET file didn't exist??? 

    Public Function Main() As Integer



        Try

            ' Setup session options

            Dim sessionOptions As New SessionOptions

            With sessionOptions

                .Protocol = Protocol.Sftp

                .HostName = "xx-xxxx.xxx-xxx.xxxx"

                .UserName = "xxxxxx"

                .PortNumber = "8822"

                .SshHostKeyFingerprint = "ecdsa-sha2-nistp521 x xx:ex:xx:fe:xx:bc:ex:cx:xx:xx:xx:xx:cx:xc:xb:xx"

                .SshPrivateKeyPath = "C:\xxxx\xxxxx\Documents\private_key.ppk"

            End With



            Using session As New Session

                ' Connect

                session.Open(sessionOptions)



                ' Download files

                Dim transferOptions As New TransferOptions

                transferOptions.TransferMode = TransferMode.Binary



                Dim transferResult As TransferOperationResult

                transferResult = session.GetFiles("\Test\Outbox\Pricelists\xxxx-pricebooks-global.xml", "C:\Users\Documents\xxxx-pricebooks-global.xml", False, transferOptions)



                ' Throw on any error

                transferResult.Check()



                ' Print results

                For Each transfer In transferResult.Transfers

                    Console.WriteLine("Download of {0} succeeded", transfer.FileName)

                Next

            End Using



            Return 0

        Catch e As Exception

            Console.WriteLine("Error: {0}", e)

            Return 1

        End Try



    End Function
