Classes Message_ProgressRange and Message_ProgressScope are improved to store start point of the range.
Method Message_ProgressScope::Value() is improved to compute the value in the current scope from the actual current value of the global progress.
Description of Message_ProgressScope class is improved.
Off-topic:
- method Message_ProgressScope::Relieve() is renamed to Close() for semantic consistency
- article in Upgrade Guide is revised and corrected
Progress indication mechanism is refactored to support incrementing progress within multithreaded algorithms.
The class Message_ProgressIndicator is only an interface to the user application.
It accumulates the progress provided by progress scopes.
The counter is protected by mutex for thread-safety.
The new class Message_ProgressScope replacing Message_ProgressSentry should be used to advance the progress.
The scopes are nested to each other to reflect the nested nature of operations.
The new class Message_ProgressRange should be used to pass the progress to sub-scopes.
All OCCT algorithms involving progress indication have been updated to new API.
Improvements in Draw_ProgressIndicator:
- Separate console mode has been added in order to make possible to put the progress into std::cout instead
or in addition to the draw interpreter, instead of trigger option "-tclOutput".
- Treatment of Ctrl-Break signal has been added.
Now any operation can be aborted by Ctrl-C or Ctrl-Break keystroke.
Added new test case 'perf fclasses progr_par' for testing of parallel work of the progress.
Tests are added to control output and performance of progress indicator (bugs fclasses bug28478 and perf fclasses progress, respectively).
Implementation of class Draw_ProgressIndicator is improved to update indicator basing on achieved total progress (1% by default) instead of elapsed time since last update.
Method OSD_Chronometer::Restart() is fixed to actually reset the counter.
DRAW command readstl is improved to show progress indicator if configured (by command XProgress).
Description of class Message_ProgressIndicator is updated; code example is added in description of Message_ProgressSentry.
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack
