58 Minor changes to fix build warnings in source & testcode. Reordered testcode
59 in bld.inf to build in dependency order. Updated testcode to accomodate new
60 Base API for RThread::Create and RProcess::CommandLine which has changed
61 in recent base releases.
63 All tests run successfully in wins udeb except TTASKLAUNCHING which is not

87 o Implemented change request AALR-4EDG75 (GT Change Requests). This required adding additional
88 parameters to two RScheduler methods.
89 o Fixed defect EDNAWIR-4FQJ6A - "Registering twice with the task scheduler causes a memory leak"
90 (Symbian Defect Tracking v3.0)
91 o Fixed defect EDNAWIR-4FRFR6 - "Can't retrieve task data when target buffer is too big to hold
92 the data" (Symbian Defect Tracking v3.0)
93 o Fixed defect EDNAWIR-4FQGXP - "Cannot schedule new tasks when schedule server data file is
94 missing" (Symbian Defect Tracking v3.0)
95 o Fixed defect EDNAWIR-4GQN48 - "CClientProxy leaves with a "count" value" (Symbian Defect
102 TTime& aNextDue is new - This returns the next time a task/shedule is due.
104 TInt RScheduler::GetScheduleL(const TInt aScheduleHandle, TScheduleState& aState,
105 CArrayFixFlat<TScheduleEntryInfo>& aEntries,
106 CArrayFixFlat<TTaskInfo>& aTasks,
110 TTime& aNextDue, TSchedulerItemRef& aRef are new - This returns the Schedule reference
111 for the taskId provided as parameter one, and also the next due time for this schedule.
113 TInt RScheduler::GetTaskInfoL(const TInt aTaskId, TTaskInfo& aTaskInfo, TPtr8& aTaskData,
114 TSchedulerItemRef& aRef, TTime& aNextDue);
120 o Added TScheduleBackup::OpenStoreOrCreateLC(...) which attempts to open the schedule
121 store, or if it doesn't exist, recreates it (schstore.cpp/h).
122 Updated TScheduleBackup to use this new method rather than opening the store explicitly.
124 o Amended CSchSession::RegisterClientL(...) to delete any existing iClient instance should
125 the client session have already registered previously (fixes memory leak).
127 o Added two new tests to tsch.cpp project, one to check the added Change Request functionality,
128 and the other, an additional task Id test.
130 o Added THelpers.cpp/h to provide support methods for the TSch test project.
135 All tests pass under WINS.
140 All projects for this component build for all platforms.
145 o testOOM<...> is bugged and no longer works due to the addition of error logging. This is not
146 a defect in the logging, but a defect in the test code.
147 o The tests are based heavily on timing. This prevents satisfactory testing on a target device.
148 Update the test exe and test code to use a semaphore to indicate successful exection rather than
149 relying on a timed delay.

156 Added functionality to report and store task launching, and return value errors
157 to the log engine by implementing CClientProxy::FailedToExecute().
161 1) Renamed FailedToExecute() to FailedToExecuteL() as this method allocates memory and
162 may potentially leave.
164 2) Added new mixin MExecutorErrorHandler to the task executor header file (schexec.h).
165 The CClientProxy now implements the virtual function defined within this class, and
166 the task executor now requires a reference to this class during construction (this is
167 not an optional mixin). Should an error be returned by the launched task, then the
168 virtual function implemented by this mixin is called and error cleanup may occur.
170 3) Added new (private) active object, CLogSubmitter, to the CClientProxy class which
171 manages the submission of the log event to the log server (submission occurs
172 asynchronously). The active object waits for the completion of the submission, and
173 after completion has occurred, the CLogEvent object is destroyed.
175 In order to start the submission process, the active scheduler must be started.
176 Due to the nature of the task manager, the next active object to have its RunL
177 called is not necessarily the CLogSubmitter (another task may be scheduled to run
180 Because potentially many tasks may be executed in parallel, multiple errors may
181 occur at the same time for any single client. This therefore requires a nested
182 start of the active scheduler when the CClientProxy::iLogSubmitter is already active.
184 4) In order to store a contextual error message in the log, FailedToExecuteL() now
185 has another overload. This simply takes two parameters, the first being the error
186 code, and the second the error message to write to the log.
188 As the contextual error message can only be defined at the point in time immediately
189 before the tasks are executed, the error message is prepared by the CClientProxy
190 class (in CClientProxy::BuildTaskErrorMessageL(...)) and is subsequently 'given'
191 to the CTaskExecutor so that (should an error occur) it can inform the CClientProxy,
192 by way of the MExecutorErrorHandler mixin, of the error that occurred and the appropriate
193 message to write to the log.
195 Changed a lot of source files to use _LIT rather than #defined'd _Ls
197 Also correctly capitalized full paths in some source files (i.e. "C:\system" => "C:\System").
