All notable changes to moddy will be documented in this file.
The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.
- Complete refactoring of moddy source code to be pep8 compliant. Files, methods, parameters and classes have been renamed! API is no longer compatible with moddy 1.x. Models created for moddy 1.x have to be adapted! See "Porting from Moddy 1 to 2" in the online documenation for details!
- Static svg diagram generator
- monitoring feature: sim.addMonitor/deleteMonitor and vThread.waitForMonitor
- simPart _stateInd member to reflect the last text set via setStateIndicator
- lost message were propagated to input ports recvStart method
- moddy/lib/traceSearch - to search for events in traced events
- restarted vthreads didn't work correctly if they have been busy before they have been killed
- simIOPort.injectLostMessageErrorBySequence didn't work
- moddy/lib/pdu was missing in dist
- lib/pdu.py to model Protocol data units
- Add setMsgStartedFunc for input ports to inform receiver that message transmission has begun
- VERSION no longer a global variable that may collide with other SW components
- Allow to specify a part's ports in the constructor
- Sequential programs: Allow to pass the program's function to the vThread/vSimpleProg constructor (target parameter)
- waitForMsg() method for Queuing ports
- Allow to bind multi output ports to one input port
- simulator smartBind() method to bind all ports in a single call
- all tutorials to use new comfort functions (smartBind, waitForMsg, creation of ports via constructor)
- Remove timeouts between simulator thread and vThreads, otherwise debugging impossible
- Threads that are initially preempted lose incoming messages on ports
- First installation via pip
- Installation via pip
- Documentation changed from .docx/pdf to Sphinx
- Internal directory structure: seqDiagInteractiveViewer now below moddy/
- iaViewer 0.8: search function
-
iaViewer 0.7: Fix time marker handling. Markers toggle their appearance with every click. Time delta now displayed in headline.
-
Simulator speed improved by approx factor 4..5: Replaced msg-passing deepcopy by pickle. Use specialized queues and heaps, replaced slow exec() calls.
- waitUntil() API for vThreads
- Allow vThread wait() API to wait for IOPorts (not only input ports)
- vThread communication timeout increased to 20s (was 2s, too short for heavily loaded systems)
- vThread: Corrected term "queing" -> "queuing" in port names and method names. The old miss-spelled name is still supported in queue names (not method names)
- iaViewer 0.6: Support time markers.
- support for model assertions: models can call assertionFailed(). Simulator by default stops on assertionFailure. Use
- Update User Manual
- iaViewer 0.5: Improved responsitivity: Handles now huge drawings by using deferred drawing. Support assertion failures. Fixed vScroll bug.
- support for model assertions: models can call assertionFailed(). Simulator by default stops on assertionFailure. Use sim.run(stopOnAssertionFailure=False) to override this. Simulator displays a list of all assertion failures at end of simulation
- Support remote controllable vThreads: Create a vThread with remoteController=True and the vThread will have then a moddy port "threadControlPort" which expects "start" or "kill" messages. Unlike normal vThreads, remoteControlled threads do not start automatically, but are waiting for "start" command. If a thread is terminated, all pending timers are stopped, all receive queues are cleared and no messages can be received while terminated.
- New tutorial: 6_vthreadRemoteControlled.py to demonstrate remote controllable vThreads and model assertions
- Allow vThreads to exit their main loop: in that case, the thread is dead (a remoteControlled thread may be restarted)
- simPart.time() as a shortcut for models (models can call self.time() instead of self._sim.time())
- support sim.run(maxEvents=None) for infinite number of events.
- commonly used status box appearance colors bcXXX, e.g. bcWhiteOnRed (see moddy/init.py)
- simulator's incorrect stop time handling. Sometimes, last event has not been processed
- simulator now terminates correctly (without a timeout) when a model thread throws an exception
- iaViewer 0.3: Improved responsitivity: Removed limitation where labels are no more placed when more than 100 labels visible. Only a few Labels are now placed in each animationframe.
- iaViewer 0.2: Watched variables were not shown if the part containing variable was not shown
- Exception if output files were in current directory (and not in a subdirectory)
- iaViewer 0.2: Part boxes can now be moved (dragged) on
- For all output files, create intermediate missing directories to output files
- Sequence Diagram Interactive Viewer: Hangups while time zooming
- Sequence Diagram Interactive Viewer: improved performance
- Model structure graph generation was broken for ports with vtIOPorts (double connections were shown)
- Alpha version 0.1 of sequence diagram interactive Viewer
- Support messages to self (not shown in static SD)
- Support ioPort loopBind()
- Variable watching support
- Lost Messages support
- Target Trace Import feature
