crystal-facet-uml Architecture

Crystal-Facet-Uml cfu Image C0525

Introduction and Goals

Introduction and Goals UMLUseCaseDiagram D0001

crystal-facet-uml creates sysml/uml diagrams to document system and software architecture.
As software architect, you create a set of diagrams describing use-cases, requirements, structural views, behavioral and deployment views.
This diagram shows the use-cases that crystal-facet-uml addresses.

Introduction and Goals, Use Cases on Data Model

Design consistent architecture diagrams UseCase C0008

The main goal of crystal facet uml is to create a set of consistent uml diagrams. Diagrams help in desinging a system that satisfies a set of requirements and decomposes the system into smaller entities.
Consistency encompasses:
- Consistent relations between objects
- Consistent naming of objects
- Consistent locations of objects in diagrams

This diagram lists the main features of crystal facet uml.

Use Cases on Diagrams

Show Classifiers req UseCase C0009

Classifiers are drawn to diagrams one classifier is visible in one or multiple diagrams

··> Show multiple instances in same diagram Trace R0058

··> Mark Classifiers Trace R0061

··> Classifier has relations Trace R0062

··> Classifier is implicit instance Trace R0795

··> Classifier is explicit instance Trace R0796

Use Cases on Diagrams

Classifier is contained (child) req Requirement C0010

A Classifier can either exist stand-alone or be a sub-element of another classifier.

Use Cases on Diagrams

Show multiple instances in same diagram req Requirement C0011

One and the same classifier can be shown in a diagram multiple times (either as class/type or as instance)

Use Cases on Diagrams

Classifier has relations req Requirement C0012

A classifier can have zero, one or many relations; these may be of one or of differnet types. Circular dependencies may be forbidden if semantics undefined.

··> Classifier is contained (child) Refine R0063

Use Cases on Diagrams

Mark Classifiers req Requirement C0013

A classifier can be highlighted in one or several diagrams. The highlighting may be different in different diagrams where the classifier is shown.

highlight Operation F0007

grey out Operation F0008

Use Cases on Diagrams

Classifier is explicit instance req Requirement C0014

A classifier can be an explicitly modelled instance of another classifier

Use Cases on Diagrams

Classifier is implicit instance req Requirement C0015

A classifier can represent an anonymous (implicit) instance without defining an explicit instance relation

Use Cases on Diagrams

Diagrams are hierarchical req Requirement C0016

There is one root diagram. All other diagrams shall have a parent diagram.

Provide means to use the identical classifier in multiple diagrams

Use Cases on Data Model

Search Classifiers, find diagrams req UseCase C0259

Use Cases on Data Model, ctrl: consistency

All model elements must be visible req Requirement C0467

Whatever elements are stored in the model, these must be visible in some diagram. Otherwise 1) these cannot be reviewed and
2) their intention is unclear.

Export model req UseCase C0319

The model can be exported in a machine-readable format.

Import/Sync Use Cases

Import model req UseCase C0408

The model can be imported from a machine-readable data format.
Supported modes are:

- Import all elements to an empty database
- Import only new elements, ignore existing and deleted elements (or notify on modifications)
Unsupported modes are:

- Import new elements, overwrite existing elements, ignore deleted elements
- Import new elements, overwrite existing elements, delete missing elements
- 3-Way merge
The unsupported use cases have to be solved by external scripts if needed. A possible solution may be to a) export all elements, b) modify the export, c) import all elements to a new, empty database.

Solution Strategy

Solution Strategy UMLComponentDiagram D0040

During operation, crystal-facet-uml runs as application based on the libraries sqlite and gtk.

External Libraries, Solution Strategy

sqlite3 Package C0007

SQL database

External Libraries, undo control flow, Solution Strategy, gui paste from clipboard

gtk4 Package C0005

Toolkit which provides
- Windows and Widgets
- User Input handling

Solution Strategy

technical strategy Comment C0185

crystal-facet-uml shall be portable, therefore as few as possible 3rd party libraries shall be linked against:
- To store the data, the sqlite database is used.
- To interact with the user, gtk is used.

··> crystal-facet-uml application Dependency R0244

··> gtk4 Dependency R0245

Solution Strategy

user interface strategy Comment C0186

The user shall
- focus on the semantics of the diagrams, not on the layout
- be able to order classifiers left-to-right and top-to-bottom
- be forced to use the same elements in different diagrams
crystal-facet-uml shall
- auto-layout classifier locations and sizes,
- auto-layout features and relationships
- hide the meta-model from the user

In the current implementation, the software runs single-threaded.
If running multiple threads, a possible implementation is that the data_database object exists just once and provides an sqlite3 connection object in SQLITE_CONFIG_SERIALIZED mode (see https://sqlite.org/threadsafe.html ) Every thread gets its own readers and writers (to separate the statements-with-bound-variables and statement-string-buffers)
There is a chance that thread-2 performs multiple independant queries while thread-1 performs a write transaction. This is expected to not cause a problem, given the current sequences of statements.

Multithreading in GUI Mode

Multithreading in GUI Mode UMLActivityDiagram D0112

Concept for Multithreading: In general, all modules shall work in a multithreaded environment.

- The gui module requires own data structures in order to be thread-safe and relies on the base libraries gtk, gdk which need to support multi-threading,
- The pencil module requires own data structures in order to be thread safe and relies on the base libraries pango and cairo which need to support multi-threading.
- The data module does not need own data structures, it comes with a module-wide lock in the database_t structure.
- The ctrl module requires own data structures in order to be thread safe. This limitation would need to be changed if a multi-threaded gui should access a single ctrl and data instance. (Currently, the software is single-threaded)

Trace, Log, Assert, Error Propagation, Memory Management

Assert

Assert SysMLRequirementDiagram D0048

Assert

Program Assert Requirement C0220

Use "if(COND) {...} else {LOG("error");assert(false);}" statements to ensure code+data consistency towards other software modules, This makes code more robust if unexpected behavior occurs during operation.

Assert

Assert-Goal Comment C0221

Maintainability:
- When modifying code, illegal modifcations shall be detected early
Analyzability:
- When receiving bug reports, an anomaly in the program/data flow shall be detected early
Reliability:
- Errors in one SW module shall not cause errors in other modules
Testability:
- Assert-paths in code shall be testable

··> Program Assert Dependency R0295

··> External Data Check Dependency R0298

··> Local Assert Dependency R0299

··> Test Environment Assert Dependency R0300

Assert

Local Assert Requirement C0224

Use "assert(COND);" statements to ensure code+data consistency within one software module, These are executed in DEBUG mode only.

Assert

External Data Check Requirement C0225

Use "if(COND) {...} else {LOG("error");}" statements to ensure code+data consistency towards external input, External input may possibly not follow any specification.

Assert

Test Environment Assert Requirement C0226

Use "TEST_ENVIRONMENT_ASSERT()" statement to ensure a valid test environment. Errors always terminate the test run.

Log, Trace

Log, Trace SysMLRequirementDiagram D0049

Log, Trace

Trace-Goal Comment C0223

Trace messages shall be activated for debugging to follow the program flow and visualize the processed data.

··> Trace Dependency R0297

Log, Trace

Trace Requirement C0218

Performance:
- Deactivated trace messages shall not slow down the program by more than 1%.
- Activated trace messages shall not slow down the program by more than 10%.
- Operation performance (NDEBUG-mode) shall not be affected by trace messages.

Log, Trace

Log-Goal Comment C0222

Log Messages are written during operation to be able to analyze important events, anomalies and faults.

··> Log Dependency R0296

Log, Trace

Memory Management

Memory Management SysMLRequirementDiagram D0058

Memory Management

Stack Mem Requirement C0246

On stack, only small data structures (<10kB) shall be stored.

··> Degradation Mode Trace R0471

Memory Management

Heap Requirement C0247

Only the external libraries may use the heap.

Memory Management

Static Allocations Requirement C0248

All data structures of crystal-facet-uml shall be statically allocated.

··> Degradation Mode Trace R0470

Memory Management

Limited dynamic allocations future extension Requirement C0297

Memory may be dynamically allocated from heap for non-base use cases. The program shall continue operation if no memory is available anymore. See Performance Efficiency (Time+Resource).

··> Degradation Mode Trace R0472

Performance Efficiency (Time+Resource), Memory Management

Degradation Mode UseCase C0295

In case of low memory, the base functionality of crystal-facet-uml shall still work reliably.

Error Propagation

Error Propagation UMLUseCaseDiagram D0059

Error Propagation

Error Codes Comment C0249

When a failure is detected, it shall be logged. If a failure can be handled locally, this shall be done. Typically, an error is propagated from where it is detected to another location in the program where it can be handled. This is done using error codes.

Error Propagation

Bitmask req Requirement C0250

The error bitmask shall be designed in a way that a zero represents no error, that the bits define the error cause/type, that two errors can be merged into one error code using a bitwise or. Error codes are not netative because this makes evaluation of the bitmask difficult to understand.

U8 base classes and macros, u8 types and functions, Error Propagation

Classifier selection defines view reason_rejected Package C0090

Diagramelements define which classifiers are visible in which diagram. All features of a visible classifier are shown. All relationships are shown that have visible classifiers at both ends.
pro: simple selection rule
con: Problematic for diagrams that show possible scenarios and alternatives (e.g sequences). This solution assumes that the model is invariant for all diagrams, therefore all diagrams showing examples/scenarios have to show own instances of classes, not generic classes that are used in other diagrams.

pro: similar concept for diagrams that show options/alternatives/scenarios (as the 4 types of interaction diagrams) to diagrams that show invariants (that are all other diagrams).

pro: similar simplicity as Classifier and Port/Lifeline selection def view. The model encodes all information even when ignoring the view classes. The solution is closer to the UML proposal The xmi export would not require exceptional handlings for interactions
