1.3.0#

Fixes#

  • Exceptions raised during generator operation for C-GET and C-MOVE services now handled properly.

  • fsm.AA_4 and fsm.AA_8 now send A-P-ABORT to the service user rather than an A-ABORT

  • Fixed rejected contexts not being included in the Presentation Context Definition Results List when acting as the association Acceptor.

  • The Message ID values for C-MOVE and C-GET sub-operations now iterate instead of just re-using 1. (#315)

  • The default logging configuration no longer uses a non-NullHandler (#321)

  • Fixed Unified Procedure Step’s SOP Class UID variable names

  • Fixed memory leak caused by keeping old Association threads around after they died (#328)

Enhancements#

  • Added event-handler system as a replacement for the callback system

    • Added events.py module with the defined events, Event class and event-related support functions.

    • Added _handlers.py module with standard logging handlers

    • Added bind(), unbind(), get_handlers() and get_events() to Association and AssociationServer classes.

    • Add assoc properties to DIMSEServiceProvider and ACSE classes

  • _config.ENFORCE_UID_CONFORMANCE added which determines the level of conformance required for UIDs. If True then all UIDs are required to meet the UID rules in the DICOM Standard, if False (default) then UIDs only need to meet the length requirement. (#316, #322)

  • Support added for Modality Performed Procedure Step Management - only with the event-handler system. (#56)

Changes#

  • The following have been removed as per planned deprecation:

    • AE.start(), AE.stop(), AE.address, AE.bind_address, AE.local_socket, AE.port

    • Association.send_c_cancel_find(), Association.send_c_cancel_get(), Association.send_c_cancel_move()

  • All callback related class methods are deprecated and will be removed in v1.4. Use the event-handler system instead.

  • _config.DECODE_STORE_DATASETS is deprecated and will be removed in v1.4. Use the event-handler system instead.

  • DIMSEServiceProvider init now takes the Association as its only parameter. dul, dimse_timeout and maximum_pdu_size properties added instead.
