Summary of changes since PANIC 5.4 (Last Sourceforge release):

PyAlarm device server:

All panic times are now seconds, added deprecated message for pollings in milliseconds Quality of failed alarms set to INVALID (~DISABLED)

Solve bug on PyAlarm.GenerateReport command Solve bug on “zombie” alarm deleted/removed Move Reset notification to send_alarm() Replace phonebook entries on ACTION receivers reload global_receivers on init()

free_alarm and send_alarm methods refactored for better actions Added SendAlarm as command kill/pause events added Added MemUsage/LastUpdate attributes Properties definition moved to panic.properties Add invalid quality to disabled alarms Add FAULT state when many alarms are failed Add LastUpdate and MemUsage attributes Avoid update_locals to reread attributes if check=False Add receiver defines: $ALARM/TAG/NAME/DEVICE/DESCRIPTION/VALUES/REPORT/DATE/JSON

Implement Pause() command and kill/pause methods for thread management. LogFiles capable of saving remotely using fandango.device.FolderDS

Solved bugs on trigger_action (see documentation on github) Properties definition moved to panic.properties Added global receivers property Add Reports Cache, refactor send_alarm logging Refactor PyAlarm.parse_receivers Alarm actions will be executed before mail and snapshot. Added replacement of $DESCRIPTION,$ALARM in actions

GUI:

New panic Icon Reduce gui dependencies to speed up startup GUI adapted to Taurus 4 launcher renamed to just “panic” Solve GUI bug on empty ActiveAlarms attribute Solve getParams deprecation on Taurus4 Added User login access via UserValidator widget

API:

Logging added to AlarmAPI Added Alarm.disabled flag to_dict and ping() methods for Alarms and AlarmDS objects get_active_alarms() method added to AlarmDS AlarmDS.Enable/Disable methods now can enable both Devices and individual Alarms Added export_to_csv and export_to_dict API methods panic.Evaluate() timeout set to 1000. allow multiple filters on GlobalReceivers Add test cases for Group/Action/Clock/Reset Solve API bug on empty receivers Solve bug on AlarmAPI.put_db_properties (Wrote to device instead of free property) Solve bug in AlarmsAPI.get_global_properties Solved bug on phonebook parsing Group macro refactored (see documentation/recipes) Add api.split_formula() Change api.evaluate() timeout and checks

Release 5.4 - 2015/12

Changes in API and device server to solve several multi-host evaluation issues. Small patches required by SKA project.

Release 5.2 - New evaluate() from API/GUI, added user admins for alarms

evaluate() method adapted to be usable by GUI and test evaluation on a remote PyAlarm device Bug solved on SentEmails recording.

Release 5.1 - May 2015

PyAlarm: added try/except to update_locals() method API: get_admins_for_alarm() method added to enable some minimal access control.

Release 5.0 - May 2015

NOTE: Requires Fandango update, to use NaN values and new TangoEval macros

API: Improved group macro to use only cached values for evaluation API: Improved caselessness on API Eval: Added EvalTimes dictionary to keep the time needed on each EvaluateFormula() call. Eval: Added DEVICE, ALARMS, PANIC objects to locals() Eval: Added own Attribute values to Eval cache to avoid deadlocks when evaluating itself Enabled property, converted from string to DevVarStringArray to allow time and formulas Attributes: Removed locks from read methods (UI was locking the evaluation trend), lock is needed only on write/update actions Solved bug that didn’t send VALUES on State/Attribute exception RethrowAttribute, from boolean to string to allow choosing False/0/NaN/None Emails: solved problems string arrays and ‘r’ and ‘”’ characters Traces: shortened strings

Release 4.20

@pending: solve threads and UseProcess issues MaxAlarmsPerDay property removed (was unused) Added new GROUP macro to formula evaluation. SnapContext: Using modify instead of create context when this already exists Added methods to taurus-like get_model from alarms Email report refactored to show values in rows and parse state values. Added methods do import/export alarm configurations from .csv files EvaluateFormula converted in a Tango command callable by clients Solved bugs using SNAP as receiver. Snap: Using newest context when several match the alarm name Eval cache reduced to AlarmThreshold+1 to adjust .delta to AlarmThreshold Solved bug in SMS sending when source contains non-alpha characters

Release 4.19 @pending: solve threads and UseProcess issues Solved bugs in alarm parsing, loading .csv and loading alarms from device Added AlarmValueLabel widget

Release 4.18 Disable screen in launch script, replaced by Tango logging Added DDebug device for debugging threads AlarmsAPI.load() time consumption reduced to avoid timeouts RethrowState=False and RethrowAttribute=False will disable exception propagation from TangoEval, it allows to manage exceptions as None in the alarm formulas. Added IgnoreExceptions property Using polling period instead of timeout as keeptime on TangoEval Renamed method get_attribute_values to get_last_values

In AlarmAPI:

Added filter_alarms, export_to_csv, modify methods get/filter* methods modified to allow custom alarm lists Bugs solved in load_from_csv getCurrent will return last API instance used

Added IgnoreExceptions property children() replaced by get_basic_alarms method parse_variables replaced by parse_attributes and evaluate()

Release 4.17 2013/09/09

Added VersionNumber attribute Added methods Status/dev_status to remove automatic messages on qualities. Added self.update_locals() for a better update of alarm values, periods and conditions reviewed. fandango.threads.WorkerProcess has been optimized, PyAlarm modified to use new pause method Methods returning sorted lists

Release 4.16

References to taurus removed if UseTaurus property is False (default) Minimum polling reduced to 250 ms Using panic.PyAlarmDefaultProperties to have consitency between api/gui/device Solved bug that caused timeouts on alarm exception (time wait before finally clause) Disable method is now capable to disable alarms only for TIMEOUT argument If Enabled property is an integer, alarm changes will be ignored for INT seconds at startup; it should allow to restart devices w/out resending all active alarms; a ResetAll() can be used to rethrow all messages if wanted. CheckDisabled will manage alarm reactivation after timeout

The Panic module has been renamed to panic; several bugs have been solved and methods for enabling/disabling alarms have been added.

4.15 September 2012 Disabled LogFile by default BETA: Cache added to TangoEval to try alarm on transition.

4.14, September 2012 Added StartupDelay property Bugs solved in Snap context creation. Added user message to alarm RESET emails.
