Stack tracing

Applications started via Launchpad are required to provide a stack trace dumper. This dumper produces a stack trace when an unexpected error happens during the startup sequence.

Stack tracing for Pharo

When using Launchpad in Pharo the following dumpers are available:

• StackTraceTextDumper produces a textual stack trace written to the configured stream.
• StackTraceBinarySerializer produces a binary stack trace serialized by Fuel. This stack traces can be later opened in a Pharo image and debugged live using the familiar tooling.
• NullStackTraceDumper emits a warning and doesn't produce any stack trace. Its usage is discouraged in production environments.
