\r
513 Tango 7.2.0 has been developed and tested with omniORB 4.1.4
\r
515 Remarks about omniORB 4.1.4
\r
516 ---------------------------
\r
518 - SourceForge bug number 3054292 (client hangs on ping) is solved by a omniORB patch available in the SourceForge bug tracker
\r
519 - SourceForge bug number 3011742 (memory leak) is also solved by 2 omniORB patches available in the SourceForge bug tracker
\r
522 New / Optimized features
\r
523 ------------------------
\r
525 - The client API is now thread-safe:
\r
526 This means that you can share a pointer to a DeviceProxy class instance between several thread. Note that if one thread changes
\r
527 data like the device time-out, this change will be seen by all the other threads using this device.
\r
528 In next major release (Tango 8), a new mechanism will be implemented allowing the user to choose if he want a thread safe
\r
529 or unsafe device proxy. For compatibility reason, it was not possible to include this change in a non major release.
\r
530 - It's now possible for applications to subscribe several times to the same event (with or without the same callback object)
\r
531 - Add check on attribute dimension when using AttrData<T> class to fill polling buffer hsitory
\r
532 - Subscribe to a data ready event fails if the Attr::set_data_ready_event() method has not been called (in the server side).
\r
533 This allows application to be aware that the device could/couldn't fire data ready event
\r
534 - Added insertion operators (<<) in the DeviceAttribute class for const char * and Tango::DevString
\r
535 - Polling and logging related commands allowed only for the device lock owner when the device is locked
\r
536 - Add a way to externally fill-up the polling buffer for R/W attribute when specifying the attribute written part
\r
537 - No more database call executed by DeviceProxy constructor if it is called in a device server and the device is in the same process
\r
538 - Better management of device server started on host with several network interface (ORBendPoint option not needed any more)
\r
539 - Added a ApiUtil::get_env_var() method (static)
\r
540 - Better timeout management during re-connection in case of device server running on a host switched off
\r
541 - Add a new way to write class_factory() as a function instead of a DServer class method. Needed for PyTango on Windows using DLL
\r
542 - NaN is now taken into account in RDS alarm for float/double (and array of) attributes
\r
545 SourceForge features request

\r
759 - Stateless event subscription : an event subscription is possible now,
\r
760 even when the device server is not running. The subscribe_event method
\r
761 takes a new boolean parameter to trigger stateless event subscription.
\r
763 - Attribute::set_write_value methods have been added for spectrum and image
\r
766 - Added extratction methods to DeviceAttribute to individually extract
\r
767 read and set point values. Added methods to read the data dimensions
\r
768 which are compatible with the Java API.
\r
772 - Class dlls for Windows can be created and can be used as for UNIX now.
\r
774 - Device server now uses a database cache to get all their data during
\r
775 their starting sequence. This cache is filled in by a new Database server
\r
776 command and destroyed at the end of the startup sequence. When possible, all
\r
777 data are fetched from this cache instead of from the database.
\r
778 If it is not possible to fill in this cache for any reason, the device server
\r
779 process starts using the traditional way.
\r
781 - Optimize network calls during connection establishment between client and server
\r
783 - Implement a new timeout management for database object access. The timeout
\r
784 used has a different value when the device server is in its starting phase
\r
786 - Automatic management of a TCP connection establishment timeout for the
\r
789 - Add new Database class methods to interface the two new database server
\r
790 commands (DbGetDataForServerCache and DbDeleteAllDeviceAttributeProperty)

792 - Change the way the DB is cleanup up due to dynamic attribute deletion
\r
793 during device server shutdown

\r
799 info returned by the info() network call
\r
801 - Add 2 new Attribute::set_properties() methods which can be used in a Tango class
\r

806 - Solved deadlock when subscribing events from different threads.
\r
807 - Initialisation of memorized attributes during the init command.
\r
808 - Correction of client and server shutdown procedures when using
\r
809 the event client part.

\r
811 threading package than omnithreads.
\r
812 - Fix client multi-threading issue when a CORBA exception was received during
\r
814 - Name letters case bug in polling thread command and in polled objects
\r
815 name stored in database

839 - Ported to OmniORB 4.1, which is a major release of omniORB and
\r
840 changes the generated code from the IDL.
\r
842 - Ported to 64 bit architectures (Linux and Windows (x64))
\r
845 - Add an attribute configuration event which is pushed every time an
\r
846 attribute property changes. This allows to synchronize all client
\r
847 displays of an attribute.
\r
849 - Added new filterable fields "quality" and "delta-t" (sine last archive_event)
\r
850 to the archive event
\r
852 - Events with quality invalid are only send once as long as the quality
\r
855 - Events with exceptions are only send once as long as the exception does
\r
858 - Modified the synchronisation between the event consumer and the keep
\r
860 Exchanged the global mutexes on the channel and the callback maps
\r
861 by individual monitors for every channel and every callback.
\r
862 The monitor can time-out and will not block the event reception
\r
863 for a long time in case of problems.
\r
864 To synchronise with subscribe or unsubscribe requests, added a
\r
865 global reader writer lock around the two maps.
\r
866 The subscribe thread is the writer and the event consumer and the keep
\r
867 alive thread are the readers.
\r
869 - When removing dynamic attributes all their configuration will be deleted
\r
870 now from the database. Polling configuration and event configuration
\r
871 properties will be deleted.
\r
873 - Events are available for devices servers running with a file database
\r
874 or without database.
\r
876 - Filling polling buffer using Util::fill_attr_polling_buffer() now

884 get_host_list, get_services, register_service, unregister_service,
\r
885 get_class_for_device, get_class_inheritance_for_device,
\r
886 get_device_exported_for_class, put_device_alias, delete_device_alias,
\r
887 put_server_info, delete_server_info, get_server_class_list,

\r
892 get_class_attribute_property_history, get_class_attribute_list,
\r
893 get_attribute_alias, put_attribute_alias, ...
\r
896 - Methods to change timeouts for groups (common or individual)
\r
898 - New Util::get_tango_lib_release() method
\r
900 - Add the DeviceClass::device_destoyer() method (opposite of the
\r
903 - The polling thread is now configured without creating a separate thread
\r
904 (new argument in its ADD_OBJ_POLLING command)
\r
906 - Add omni_thread::ensure_self object in AutoTangoMonitor and
\r
907 NoSyncModelTangoMonitor classes in order to use these objects in
\r
908 threads not created by omni_thread (Python thread for instance)
\r
910 - Add device name in Tango monitor print messages
\r
912 - MAX_TRANSFER_SIZE is now 256 Mbytes
\r
914 - Removed all #ifdef for HP-aCC compiler
\r
916 - The Tango database server do not use the root account for MySQL any
\r
917 more. You can configure any account to be used via the my.cnf
\r
918 configuration files or via the environment variables MYSQL_USER and
\r
924 - Polling did not restart correctly after an Init command on a device
\r
925 server admin device
\r
927 - Bug in re-connection after a device server admin device Init, Restart or
\r
928 Devrestart command

\r
935 same name but a different definition (different data type, data
\r
938 - Several bugs when removing dynamic attributes

\r
950 created using a syntax like "host:port/a/b/c" with host and port not
\r
951 the same than the one defined by the TANGO_HOST environment variable
\r
953 - In the case of a too long delivery time for events the notifd closes
\r
954 the connection to a client. Now this case is detected in the client
\r
955 and the client will reconnect.

\r
962 *****************************************************
\r
963 - Contains a new version of the Tango database which keeps a history
\r
964 of the last changes for every property. This needs the creation of
\r
965 new tables in MySQL and a new database server.
\r
967 - Corrected the reconnection to the notification daemon in the case of
\r
969 - Increased the maximum data size to be transferred between server and
\r
970 client from 8Mbytes to 16Mbytes.
\r
971 - Since release 5.5 a server under windows could no longer be installed

983 1.) Push events but check the event configuration
\r
984 (as the polling thread). Events are fired exactly under the
\r
985 same conditions as with the polling.
\r
986 2.) Push events without configuration check.
\r
987 The event is fired without any value checking.
\r
988 - The quality event was removed and integrated as filter "quality"
\r
989 to the change event.
\r
991 - The user event was adapted to follow the structure of pushing
\r
992 change or archive events.
\r
994 - Event reconnection will follow now when a server was moved to a
\r
995 different host. The connection will be rebuild to the new notifd.
\r
997 - Polling configuration for attributes and commands specified in
\r
998 the code with Pogo are written to the database at server start-up.
\r
999 The polling will start immediately and no longer on a first reading
\r
1002 - The transparent reconnection is now the default reconnection mode.
\r
1004 - Naming requests to the database are cached for a DeviceProxy.
\r
1005 A reconnection request will be emitted only once a second for a
\r
1006 DeviceProxy connection.
\r
1007 The same feature is implemented in the Java api.
\r
1009 - Debugging is now possible with the Linux 2.6 kernel.
\r
1010 - Support of gcc 4.0
\r
1011 - Support of VC7 and VC8 under Windos.
\r
1012 - Integration of code for device servers written in Python.
\r
1015 - Corrected event priod handling for periodic events.
\r
1016 - Corrected rounding errors when checking the conditions.
\r
1017 of change and archive events.
\r
1018 - Corrected constructor for the class GroupReply.

1023 * Tango release 5.4 : Changes since version 5.3 *
\r
1025 *****************************************************
\r
1027 - Stopped the automatic polling startup of attributes at event subscription.
\r
1028 All polling has be be configured manually!
\r
1029 Subscription to events is only possible if the event properties
\r
1030 for an attribute are properly configured and the polling is started!
\r
1032 - An exception during initialisation of memorized attributes
\r
1033 will no longer result in an exit of the server.
\r
1035 - Memorized attributes can be used in two ways now.
\r
1036 1) The setpoint gets initialised during a server startup.
\r
1037 No write happens on the attribute.
\r
1038 2.) The setpoint gets initialised during a server startup
\r
1039 and is written to the attribute.
\r
1040 The initialisation mode can be triggered by
\r
1041 Attr::set_memorized_init(bool write_on_init) method
\r
1042 during attribute creation.
\r
1043 The two options are supported by Pogo.
\r
1045 - The archive event behavior has changed. The archive period
\r
1046 is no longer set to 10 seconds as default. If no period is
\r
1047 specified, no periodic archive event is send.
\r
1050 - Corrected the wrong archive period reading after a
\r
1053 - Changed DServerClass::instance() to return an exception
\r
1054 in the case of a not initialised object.
\r
1055 The exit() killed the server during a startup when
\r
1056 a client sends requests to early.
\r
1058 - Changed the clean-up mechanism when shutting down
\r
1059 the ORB. Destroy ORB when returning from run().
\r
1060 In 5.3 This was done in the main and when missing
\r
1061 caused some threads to hang-up with the Linux kernel
\r
1064 - Avoid calling Device_3Impl::status2attr() during
\r
1065 attribute reading when an error was detected.
\r
1066 Avoids segmentation fault in status2attr().
