This is not + a defect in the logging, but a defect in the test code. +o The tests are based heavily on timing. This prevents satisfactory testing on a target device. + Update the test exe and test code to use a semaphore to indicate successful exection rather than + relying on a timed delay. + + +Release 005 +----------- +By AlexW 22 November 1999 + +Added functionality to report and store task launching, and return value errors +to the log engine by implementing CClientProxy::FailedToExecute(). + +Changes +------- +1) Renamed FailedToExecute() to FailedToExecuteL() as this method allocates memory and +may potentially leave. + +2) Added new mixin MExecutorErrorHandler to the task executor header file (schexec.h). +The CClientProxy now implements the virtual function defined within this class, and +the task executor now requires a reference to this class during construction (this is +not an optional mixin). Should an error be returned by the launched task, then the +virtual function implemented by this mixin is called and error cleanup may occur. + +3) Added new (private) active object, CLogSubmitter, to the CClientProxy class which +manages the submission of the log event to the log server (submission occurs +asynchronously). The active object waits for the completion of the submission, and +after completion has occurred, the CLogEvent object is destroyed. + +In order to start the submission process, the active scheduler must be started. +Due to the nature of the task manager, the next active object to have its RunL +called is not necessarily the CLogSubmitter (another task may be scheduled to run +instead). + +Because potentially many tasks may be executed in parallel, multiple errors may +occur at the same time for any single client. This therefore requires a nested +start of the active scheduler when the CClientProxy::iLogSubmitter is already active. + +4) In order to store a contextual error message in the log, FailedToExecuteL() now +has another overload. This simply takes two parameters, the first being the error +code, and the second the error message to write to the log. + +As the contextual error message can only be defined at the point in time immediately +before the tasks are executed, the error message is prepared by the CClientProxy +class (in CClientProxy::BuildTaskErrorMessageL(...)) and is subsequently 'given' +to the CTaskExecutor so that (should an error occur) it can inform the CClientProxy, +by way of the MExecutorErrorHandler mixin, of the error that occurred and the appropriate +message to write to the log. + +Changed a lot of source files to use _LIT rather than #defined'd _Ls + +Also correctly capitalized full paths in some source files (i.e. "C:\system" => "C:\System"). + + +Release 004 +--------- +Steve Etherington 26 October 1999 +Builds under current system. +No significant changes + +Release 001 +----------- +Built by WilliamB 26 June 1998 + +Uses e32 128, e32tools 091, e32toolp 091, e32utils 018, f32 095, bafl 078, store 049 + +Release valids on a clean drive. + +First release of task scheduler. + +Deb/Rel interoperable. + +Test code run and passed for all builds, except Y2K test code (tschy2k.exe) which +hasn't been run because the test plan hasn't been approved yet + since 003
