plainbox dev crash [-h] (-c | -H)
Crash the application
This command is designed to crash or hang the application.
Using this command a developer can inspect the built-in development and debugging features available in Plainbox. Specifically, there are several options available to the top-level plainbox command (they have to be used before the dev crash syntax) that allow to enable one of the following actions:
If plainbox is invoked with the --pdb command line option then all uncaught exceptions are handled by starting a debugger session. Using the debugger a developer can inspec the execution stack, including all the threads, local and global variables, etc..
If plainbox is invoked with both the --pdb and the --debug-interrupt command line options then a KeyboardInterrupt exception is not ignored, as it usually is, and instead it allowed to bubble up the command line implementation call stack until it starts the interactive debugger session.
-c, --crash | raise an exception |
-H, --hang | hang the application with a busy loop |
A debugger session on exception:
plainbox --pdb dev crash --crash
A debugger session on keyboard interrupt:
plainbox --pdb --debug-interrupt dev crash --hang
