\r
13 * Tango release 6.1.0 : Changes since version 6.0.0 *
\r
15 *******************************************************
\r
17 - Stateless event subscription : an event subscription is possible now,
\r
18 even when the device server is not running. The subscribe_event method
\r
19 takes a new boolean parameter to trigger stateless event subscription.
\r
21 - Attribute::set_write_value methods have been added for spectrum and image
\r
24 - Added extratction methods to DeviceAttribute to individually extract
\r
25 read and set point values. Added methods to read the data dimensions
\r
26 which are compatible with the Java API.
\r
30 - Class dlls for Windows can be created and can be used as for UNIX now.
\r
32 - Device server now uses a database cache to get all their data during
\r
33 their starting sequence. This cache is filled in by a new Database server
\r
34 command and destroyed at the end of the startup sequence. When possible, all
\r
35 data are fetched from this cache instead of from the database.
\r
36 If it is not possible to fill in this cache for any reason, the device server
\r
37 process starts using the traditional way.
\r
39 - Optimize network calls during connection establishment between client and server
\r
41 - Implement a new timeout management for database object access. The timeout
\r
42 used has a different value when the device server is in its starting phase
\r
44 - Automatic management of a TCP connection establishment timeout for the
\r
47 - Add new Database class methods to interface the two new database server
\r
48 commands (DbGetDataForServerCache and DbDeleteAllDeviceAttributeProperty)
\r
50 - Change the way the DB is cleanup up due to dynamic attribute deletion
\r
51 during device server shutdown
\r
53 - Default value for the "doc_url" part of the info() network call changed
\r
54 to "http://www.tango-controls.org"
\r
56 - Add new methods allowing a better way to set the CVS tag and CVS location
\r
57 info returned by the info() network call
\r
59 - Add 2 new Attribute::set_properties() methods which can be used in a Tango class
\r
60 init_device() method
\r
64 - Solved deadlock when subscribing events from different threads.
\r
65 - Initialisation of memorized attributes during the init command.
\r
66 - Correction of client and server shutdown procedures when using
\r
67 the event client part.
\r
68 - Corrected the event synchronisation when a client is using another
\r
69 threading package than omnithreads.
\r
70 - Fix client multi-threading issue when a CORBA exception was received during
\r
72 - Name letters case bug in polling thread command and in polled objects
\r
73 name stored in database
\r
74 - One re-connection case was not "transparent"
\r
75 - Clarify some exception messages
\r
76 - Polling thread synchronisation bug for internal commands start-polling, stop-polling
\r
78 - Bug in the admin device RemObjPolling command related to polling
\r
79 properties management (When the removed object was last polled object)
\r
80 - Bug in asynchronous call in PUSH_CALLBACK mode when used intensively
\r
81 - Polling configuration mismatch after an Init command on the admin device
\r
82 - The DbGetDeviceList database command now has the same wildcard for its two
\r
84 - Bug in the remote "info" call for devices implementing IDL3
\r
85 (missing CVS Tag and CVS location)
\r
86 - Bug when getting the State history using the command_history() calls
\r
87 - Windows specific: Device server configured as "daemon" correctly starts on
\r
88 a windows host with netowrk connection unavailable when the DS starts
\r

93 * Tango release 6.0 : Changes since version 5.5.2 *
\r
95 *****************************************************
\r
96 - Ported to OmniORB 4.1, which is a major release of omniORB and
\r
97 changes the generated code from the IDL.
\r
99 - Ported to 64 bit architectures (Linux and Windows (x64))
\r
102 - Add an attribute configuration event which is pushed every time an
\r
103 attribute property changes. This allows to synchronize all client
\r
104 displays of an attribute.
\r
106 - Added new filterable fields "quality" and "delta-t" (sine last archive_event)
\r
107 to the archive event
\r
109 - Events with quality invalid are only send once as long as the quality
\r
112 - Events with exceptions are only send once as long as the exception does
\r
115 - Modified the synchronisation between the event consumer and the keep
\r
117 Exchanged the global mutexes on the channel and the callback maps
\r
118 by individual monitors for every channel and every callback.
\r
119 The monitor can time-out and will not block the event reception
\r
120 for a long time in case of problems.
\r
121 To synchronise with subscribe or unsubscribe requests, added a
\r
122 global reader writer lock around the two maps.
\r
123 The subscribe thread is the writer and the event consumer and the keep
\r
124 alive thread are the readers.
\r
126 - When removing dynamic attributes all their configuration will be deleted
\r
127 now from the database. Polling configuration and event configuration
\r
128 properties will be deleted.
\r
130 - Events are available for devices servers running with a file database
\r
131 or without database.
\r
133 - Filling polling buffer using Util::fill_attr_polling_buffer() now

139 - A bunch of new methods was added to the C++ database API to implement
\r
140 the same functionality as the Java database API.
\r
141 get_host_list, get_services, register_service, unregister_service,
\r
142 get_class_for_device, get_class_inheritance_for_device,
\r

150 get_attribute_alias, put_attribute_alias, ...
\r
153 - Methods to change timeouts for groups (common or individual)
\r
155 - New Util::get_tango_lib_release() method
\r
157 - Add the DeviceClass::device_destoyer() method (opposite of the
\r
160 - The polling thread is now configured without creating a separate thread
\r
161 (new argument in its ADD_OBJ_POLLING command)
\r
163 - Add omni_thread::ensure_self object in AutoTangoMonitor and
\r
164 NoSyncModelTangoMonitor classes in order to use these objects in
\r
165 threads not created by omni_thread (Python thread for instance)
\r
167 - Add device name in Tango monitor print messages
\r
169 - MAX_TRANSFER_SIZE is now 256 Mbytes
\r
171 - Removed all #ifdef for HP-aCC compiler
\r
173 - The Tango database server do not use the root account for MySQL any
\r
174 more. You can configure any account to be used via the my.cnf
\r
175 configuration files or via the environment variables MYSQL_USER and
\r
181 - Polling did not restart correctly after an Init command on a device
\r
182 server admin device
\r
184 - Bug in re-connection after a device server admin device Init, Restart or
\r
185 Devrestart command
\r
187 - Two small memory leaks when dealing with dynamic attributes
\r
189 - Admin device did not handle device alias in its DevPollStatus command
\r
191 - Bug in add_attribute() method if you try to add an attribute with the
\r
192 same name but a different definition (different data type, data

206 - Bug in the subsribe_event() method when the DeviceProxy has been
\r
207 created using a syntax like "host:port/a/b/c" with host and port not
\r
208 the same than the one defined by the TANGO_HOST environment variable
\r
210 - In the case of a too long delivery time for events the notifd closes
\r
211 the connection to a client. Now this case is detected in the client
\r
212 and the client will reconnect.
\r
215 *****************************************************
\r
217 * Tango release 5.5.2 : Changes since version 5.5 *
\r
219 *****************************************************
\r
220 - Contains a new version of the Tango database which keeps a history
\r
221 of the last changes for every property. This needs the creation of
\r
222 new tables in MySQL and a new database server.
\r
224 - Corrected the reconnection to the notification daemon in the case of
\r
226 - Increased the maximum data size to be transferred between server and
\r
227 client from 8Mbytes to 16Mbytes.
\r
228 - Since release 5.5 a server under windows could no longer be installed
\r
229 as a windows service. Corrected the problem.
\r
232 *****************************************************
\r
234 * Tango release 5.5 : Changes since version 5.4 *
\r
236 *****************************************************
\r
238 - Change and archive Events can be pushed manually from the code now
\r
239 without polling. Two ways are possible:
\r
240 1.) Push events but check the event configuration
\r
241 (as the polling thread). Events are fired exactly under the
\r
242 same conditions as with the polling.
\r
243 2.) Push events without configuration check.
\r
244 The event is fired without any value checking.
\r
245 - The quality event was removed and integrated as filter "quality"
\r
246 to the change event.
\r
248 - The user event was adapted to follow the structure of pushing
\r
249 change or archive events.
\r
251 - Event reconnection will follow now when a server was moved to a
\r
252 different host. The connection will be rebuild to the new notifd.
\r
254 - Polling configuration for attributes and commands specified in
\r
255 the code with Pogo are written to the database at server start-up.
\r
256 The polling will start immediately and no longer on a first reading
\r
259 - The transparent reconnection is now the default reconnection mode.
\r
261 - Naming requests to the database are cached for a DeviceProxy.
\r
262 A reconnection request will be emitted only once a second for a
\r
263 DeviceProxy connection.
\r
264 The same feature is implemented in the Java api.
\r
266 - Debugging is now possible with the Linux 2.6 kernel.
\r
267 - Support of gcc 4.0
\r
268 - Support of VC7 and VC8 under Windos.
\r
269 - Integration of code for device servers written in Python.
\r
272 - Corrected event priod handling for periodic events.
\r
273 - Corrected rounding errors when checking the conditions.
\r
274 of change and archive events.

\r
280 * Tango release 5.4 : Changes since version 5.3 *
\r
282 *****************************************************
\r
284 - Stopped the automatic polling startup of attributes at event subscription.
\r
285 All polling has be be configured manually!
\r
286 Subscription to events is only possible if the event properties
\r
287 for an attribute are properly configured and the polling is started!
\r
289 - An exception during initialisation of memorized attributes
\r
290 will no longer result in an exit of the server.
\r
292 - Memorized attributes can be used in two ways now.
\r
293 1) The setpoint gets initialised during a server startup.
\r
294 No write happens on the attribute.
\r
295 2.) The setpoint gets initialised during a server startup
\r
296 and is written to the attribute.
\r
297 The initialisation mode can be triggered by
\r
298 Attr::set_memorized_init(bool write_on_init) method
\r
299 during attribute creation.
\r
300 The two options are supported by Pogo.
\r
302 - The archive event behavior has changed. The archive period
\r
303 is no longer set to 10 seconds as default. If no period is
\r
304 specified, no periodic archive event is send.
\r
307 - Corrected the wrong archive period reading after a
\r
310 - Changed DServerClass::instance() to return an exception
\r
311 in the case of a not initialised object.
\r
312 The exit() killed the server during a startup when
\r
313 a client sends requests to early.
\r
315 - Changed the clean-up mechanism when shutting down
\r
316 the ORB. Destroy ORB when returning from run().
\r
317 In 5.3 This was done in the main and when missing
\r
318 caused some threads to hang-up with the Linux kernel
\r
321 - Avoid calling Device_3Impl::status2attr() during
\r
322 attribute reading when an error was detected.
\r
323 Avoids segmentation fault in status2attr().

771 if the server is started using Valgrind. If you want to benefit from this
\r
772 change, add the Util::server_cleanup() call at the end of your device
\r

\r
803 - Added DeviceProxy::set_transparency_reconnection() and
\r
804 DeviceProxy::get_transparency_reconnection() methods to silently handle
\r
805 device reconnection

\r
810 the class (or process) monitor is taken during device(s) creation
\r
812 - Fix bug when inserting/extracting vector in a DbDatum object. This bug
\r
813 appaers only for vector with element of different size
\r

\r
819 polling of each object (command or attribute) to be polled
\r
