PLAINBOX-DEV-CRASH(1) Plainbox PLAINBOX-DEV-CRASH(1)

NAME

plainbox-dev-crash - crash the application

SYNOPSIS

plainbox dev crash [-h] (-c | -H)


DESCRIPTION

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:

Jumping Into PDB on Uncaught Exception

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..

Jumping into PDB on KeyboardInterrupt

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.

OPTIONS

Optional arguments:

raise an exception
hang the application with a busy loop

EXAMPLES

A debugger session on exception:

plainbox --pdb dev crash --crash


A debugger session on keyboard interrupt:

plainbox --pdb --debug-interrupt dev crash --hang
