Improve pre- and post-processing for skipped transfers and failed transfers

Current Situation

• Pre-Processing occurs on the following events:
  • CommandBeforeFile
    • Processing is performed for target files that can be written.
    • Processing is dropped in case of skipped transfers
      • e.g. in case that existing should not be overwritten
        • DisableOverwriteFiles (mapping overwrite_files=false)
    • Processing is performed for the first file in case of failed transfers
      • e.g. if target folders do not exist
  • CommandBeforeOperation
    • Processing is performed in any situation
• Post-Processing occurs on the following events:
  • CommandAfterFile Event
    • Processing is performed in case of skipped transfers
    • Processing is dropped in case of failed transfers
  • CommandAfterOperation Event
    • Processing is performed in case of skipped transfers
    • Processing is dropped in case of failed transfers
      • e.g. if target folders do not exist

DesiredBehavior

• Users would want to control in which situation pre- and post-processing scripts should be executed.
• Pre-Processing
  • CommandBeforeFile
    • Attribute: enable_for_skipped_transfer.
      • The default value is false which corresponds to the behavior with previous releases.
      • Mapping: pre_command_enable_for_skipped_transfer
• Post-Processing
  • CommandAfterFile
    • Attribute: disable_for_skipped_transfer.
      • The default value is false which corresponds to the behavior with previous releases.
      • Mapping: post_command_disable_for_skipped_transfer
  • Environment variables in the SFTPPostProcessing and LocalPostProcessing:
    • YADE_FILE_TRANSFER_STATUS
      • possible values: transferUndefined, waiting4transfer, transferring, transferInProgress, transferred, transfer_skipped, transfer_has_errors, transfer_aborted, compressed, notOverwritten, deleted, renamed, ignoredDueToZerobyteConstraint, setBack, polling
    • YADE_FILE_IS_TRANSFERRED
      • possible values: 0 or 1

Configuration requirements

• XML Editor 3.0.10
