FTP Connector Release Notes for Mule 4

The Commons IO library is upgraded to version 2.13.0.

FTP Connector now supports an independent file system matcher that lists files following FTP RTF standards. Use the Case sensitive field to configure an external file system matcher as case sensitive or insensitive.

Upgraded versions of dependencies.

Added the Proxy parameter, which enables you to set the HTTP or HTTPS tunnel proxy in the FTPS Connector global configuration.

When FTP Connector attempted to use the MLSD command to list the directory, the server responded with Command Not Implemented (502) and before the connector could retry the operation with a LIST command, the server closed the connection. A call to the FEAT command is now issued to validate that MLST/MLSD commands are supported by the server.

Fixed the issue that caused incorrect initialization of streams when connection errors occurred, and which caused the streams to remain dirty and resulted in mixed up file contents. (FTPC-70)

Fixed the issue that caused the move to post-action not to work. (FTPC-67)

Fixed an issue where the Write operation was incorrectly throwing a MULE:UNKNOWN error instead of FTP:ILLEGAL_PATH. (MULE-17797)

Fixed an issue where the connector was showing an incorrect reply code when throwing an FTP error. (MULE-17815)

Fixed the FTP Listener so it is able to rename files on a POST action when renameTo is set but moveTo is left blank. (MULE-17837)

Fixed a bug where FTP connection timeout was not working if it was set to a very low value. (MULE-17867)

Improve validations on name and path parameters. (MULE-17680)

Fixed an issue where the connector was failing to list or poll directories in some servers. (MULE-17434)

Solved an issue where the FTP Listener was trying to release connections that were never obtained. (MULE-17490)

The parameters Updated in the last, Not updated in the last, and Time unit are added to the File Matcher. These parameters enable you to have a List or Listener operation that filters files by whether or not they have been updated in the specified time unit.

Adds the option to configure FTP Remote Verification.

Fixed a bug that made the read operation take more than one connection to read the file content. (MULE-17315)

Allow configuring Remote Verification in FTP config. (MULE-17369)

Fixed a bug that made the read operation fail for certain FTP servers. (MULE-17347)

Add (Not) Updated in the last capability to File Matcher in the FTP Connector. (MULE-17219)

Fixed a bug that caused the connector’s listener to skip a file due to a race condition. When the polling frequency of the listener was low, the autodelete flag was true, there was a burst of files to process, and the processing of each file took longer than the polling frequency, a file could be skipped. (MULE-16999)

The timeBetweenSizeCheck setting prevents the connector from processing files while they are being written.

FTP connector should not log the full stack trace in warn level when failing to log out a connection. (MULE-16825)

Fixed a regression that affected the use of ftp:listener without specifying a directory. (MULE-16818)

Fixed an issue that prevented reading a file that had a space in its name. (MULE-16729)

Fixed an issue that prevented virtual directories to be listed or use the polling source in them. (MULE-16625)

Improved the FTP Write operation’s performance when writing on remote servers. (MULE-16557)

Fixed a bug that prevented the usage of the list operation on some FTP server configurations. (MULE-16591)

Fixed bug that made the List operation take too long when the listed directory contained a large number of files. (MULE-16346)

Fixed bug that made the connector get stuck while reading files from a remote server, degrading performance. (MULE-16291)

FtpFileAttributes threw NPE when FTPFile date was null. (MULE-15301)

FTP:ILLEGAL_PATH is thrown during FTP write. (MULE-15104)

FTP:Write deletes the directories and files when no filename is provided. (MULE-15172)

FTP connector should better inform on connection errors. (MULE-14993)

ftp:listener has undescriptive display name. (MULE-14585)

Added a message source that automatically polls for new files, while handling clustering, idempotency, post actions, and watermark automatically.
