SFTP Connector Release Notes - Mule 4

SFTP Connector 2.0.0 no longer supports the jcraft JSCH library. The connector now uses the Apache Mina SSHD library.

The List operation no longer fetches the content of each file. Now, the payload of each list item contains the complete path to the found file or directory.

The connector no longer uses the mule.sftp.useHomeDirectory system property. SFTP Connector now uses the default home directory.

The SFTP Regular Size file attribute is renamed to Regular File, because its behavior is not related to size. The file attribute value is a file (true) or a directory (false).

SFTP Connector 2.0.0 does not support ciphers 3des-ctr and arcfour. For more information, refer to Supported Ciphers.

The SFTP proxy protocol works only with HTTP and SOCKS5. SOCKS4 support is not supported.

SFTP Connector no longer uses javax.activation to resolve the media types of the files. The connector now uses Apache Tika, which can result in different media file interpretations.

The connector changed the classes to manage the date from LocalDateTime to ZonedDateTime.

The deprecated Encoding parameter in the configuration and Write operation is removed. The connector uses Mule’s default encoding.

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

Added more error and debug level logging information.

Fixed an issue where the SFTP Connector threw a MULE:CONNECTIVITY exception instead of an SFTP:CONNECTIVITY exception for all the operations (SE-19522).

SFTP Connector now throws an SFTP:ACCESS_DENIED Mule error code instead of a MULE:UNKNOWN code if the connector does not have the required permissions to read from or write to a file (SE-16476).

Improved error handling for the Write operation. SFTP Connector now throws an SFTP:FILE_DOESNT_EXIST Mule error code instead of a MULE:UNKNOWN code (SE-15186).

Libraries that may contain vulnerabilities were updated. (MULE-16747)

Fixed a bug that made the time between a size check not behave as expected when the time unit was not milliseconds. (MULE-17004)

SFTP Connector listener may skip a file given a special configuration. (MULE-15852)

Change in behavior of the SFTP connector for Mule 4 with regard to directory paths. (MULE-15173)

SFTP authentication methods displayed incorrectly / missing (MULE-15185)

SFTP is not reconnecting after experiencing a disconnect (MULE-15196)

You can make use of timeBetweenSizeCheck to prevent the connector from processing files while they are being written.

Fixed an issue that happened when using a filter by filenamePattern, failing to search files recursively in folders.

Add CustomSftpLogger for JSCh. (MULE-14738)

SFTP getting partial file. (MULE-14824)
