This project aims to provide a visualization tool for traces from Java Pathfinder. Java Pathfinder (JPF) can show the programme trace leading to a property violation, e.g. deadlock. The new panel, which is built upon jpf-shell, visualizes the programme trace to help understand the nature of failures and properties .
-
Java 8 (OpenJDK version 8 will work).
-
Apache ant and Gradle (will self-install upon compilation).
Optional: The two latter packages are available as a pre-compiled ZIP file alongside with an extended version of jpf-visual that also handles JVM traces: VA4JVM.
You can get the source code of jpf-visual by typing in the terminal:
git clone https://github.com/qiyitang71/jpf-visual
The jpf-visual comes with a jpf.properties file for configuration with JPF. The file should work if you have checked out jpf-visual as a subdirectory of the overall jpf repository, with jpf-core and jpf-shell being another subdirectories. For example, JPF resides in project/jpf-core, the extension in project/jpf-visual. Note: you will have to have site.properties.
To compile the jpf-visual project, we recommend building sources with Apache Ant. As said above, jpf-core needs to reside in project/jpf-core and jpf-shell needs to reside in project/jpf-shell if the extestions is in project/jpf-visual. To build with Ant, switch to the directory where the jpf-visual extension is located (where build.xml file is located), and run
ant
Installing jpf-visual is just like installing any other jpf project. Make sure to add jpf-visual's path to the extensions property in your site.properties file. Usually adding the following lines to your ~/.jpf/site.properties will work:
#Visual extention
jpf-visual = /path/to/the/visual/project/jpf-visual/
extensions+=,${jpf-visual}
If you want to run your own program, the easiest way to execute JPF and use trace-server with several options is to create an application property file. For example, you can create property file like this:
target=[Application]
target_args=[application_args]
classpath=[classpath to your application]
sourcepath=[sourcepath to your application]
# print trace when property is violated
report.errorTracePrinter.property_violation=trace
# register console errorTracePrinter as a publisher
report.publisher+=, errorTracePrinter
report.errorTracePrinter.class=ErrorTracePrinter
#turn on the shell
shell=.shell.basicshell.BasicShell
#turn on the new panel
shell.panels+= ,errorTrace
shell.panels.errorTrace=ErrorTracePanel
