Closed Issue: Unable to parse the directory list: String was not recognized as a valid DateTime. [6224]

alexp — Thu, 16 May 2013 11:06:28 GMT

I've been testing the AlexFTPS component to do some automated FTP directory synchronization and I wanted something that would support FTPS as well as plain FTP. My initial tests were against a Filezilla server over FTPS and everything works beautifully. However, my other test server is a Microsoft FTP server (version unknown) using standard FTP.

When I issue a GetDirectoryList() against the appropriate directory, I'm getting an AlexPilotti.FTPS.Common.FTPException with the message "Unable to parse the directory list." with an inner exception of System.FormatException with a message "String was not recognized as a valid DateTime.

I executed a GetDirectoryListUnparsed() against both servers and compared the date/time strings. The difference is subtle but the Filezilla server returns a date as Feb 08 05:19 and the Microsoft server is returning Feb 8 5:19. Using Reflector and stepping through code, I see the issue is the extra space between the 8 and the 5. A zero is added in front of the 8 in place of the space but the space in front of the 5 remains and when DateTime.ParseExact is executed with a format of "MMM dd HH:mm", the exception is thrown.

I just wanted to document this minor issue. I've attached a text file containing the unparsed directory list with an example of the offending date.

For now, I can use GetDirectoryListUnparsed() and write a parsing routine specifically for this server.

Commented Issue: FEAT 211 No extension supported [8218]

jwikman — Tue, 14 May 2013 21:12:53 GMT

I have a server that responds to the FEAT command with "211 No extension supported", causing

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Comments: ** Comment from web user: jwikman **

I've got the same issue with a ftp server.

There is a simple fix for this in FeatCmd()

Change
```
features.RemoveAt(0);
features.RemoveAt(features.Count - 1);
```
To:
```
if (features.Count > 0)
features.RemoveAt(0);
if (features.Count > 0)
features.RemoveAt(features.Count - 1);

```

Created Issue: CheckFeature to test command availability [8729]

Jissai — Fri, 10 May 2013 09:27:45 GMT

Hello,

Due to the different ftp server implementing different command sets, I think it could be interesting to have CheckFeature() publically available.

in FTPSClient.cs
+public bool CheckFeature(string feature)
- private bool CheckFeature(string feature)

Commented Issue: Mocking capabilities [8722]

Jissai — Fri, 10 May 2013 07:59:55 GMT

Hello,

I am coding a project using Alex FTPS Client as a library to provide FTP capabilities.

I use MoQ to unit test my code, but i can't mock FTPSClient. The problem is most of mocking libraries need the mocked code to be an interface, an abstract or non-sealed class.

Would it be possible to make Alex FTPS Client mockable ?

Thanks
Comments: ** Comment from web user: Jissai **

Hello,

I tried the workaround and removed "sealed".
I go one step further but apparently when mocking a class, MoQ needs the methods to be virtual.
I confirmed this by making "Connect" methods virtual.
The better approach would be to have interface though.

Thank you.

alexp — Thu, 09 May 2013 15:56:49 GMT

Sure.

As a workaround for the moment you can just remove "sealed" from:

public sealed class FTPSClient : IDisposable

and recompile the solution.

Hi,
While logging on a ftp server (of which I can't disclose the adress/login, sorry) i've got an accurate exception. Please notice that filezilla also fails to connect to.

This is the stacktrace :

This is the corresponding filezilla verbose log (in french) :

The server is pure FTP (no security layer) with login/password.

Created Issue: PutFile() writes empty file on server when local file does not exist. [8467]

dmarkle — Wed, 19 Dec 2012 18:55:12 GMT

When calling PutFile() on a file which does not exist on the local machine, the FTPS library writes a 0-byte file on the FTP server.

This would appear to be because PutFile() opens the stream to the remote server before opening the local file.

using (Stream s = PutFile(remoteFileName))
return SendFile(localFileName, remoteFileName, s, transferCallback);

I have temporarily patched it in my copy of the code by doing an existence check inside PutFile like so:

public ulong PutFile(string localFileName, string remoteFileName, FileTransferCallback transferCallback) {
if (!File.Exists(localFileName))
throw new FileNotFoundException(String.Format("{0} does not exist on the local machine."));

using (Stream s = PutFile(remoteFileName))
return SendFile(localFileName, remoteFileName, s, transferCallback);
}

However, a better solution may be to open the local stream *before* opening the remote stream.

This turned out to be a big problem for us -- in our particular situation, we laid down a number of 0-byte files, but since our vendor denied us modify access to what we put on their server, there was no way we could correct the data after uploading it with their help, so this issue is of some real-world significance.
