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.
Fixed bugs that occurred when using the default std::cout from Message::DefaultMessenger() instead of Draw_Printer
A dedicated option was added to Draw_ProgressIndicator, for outputting data to the tcl when performing tests
Added -tclOutput parameter to XProgress command
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.
- Class OSD_EnvironmentIterator is removed (not used, and would definitely fail under Windows if tried)
- Methods UserId() and GroupId() removed from OSD_FileNode (cannot be made portable, as there is no integer IDs of user and group on Windows)
- Draw_ProgressIndicator corrected to properly pass address via Tcl
- OSD_File.cxx: local function is refactored to avoid senseless encoding / decoding of results
- OSD_Process::UserId() method removed, as it cannot be made cross-platform (no integer IDs on Windows)
- OSD_Thread: use WinAPI conversion functions to avoid warnings
- OSD_WNT.cxx: recursion counter passed via function argument instead of TLS
- TDF_LabelMapHasher revised to use correct hasher function for an address
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
