Plack::Middleware::StaUseraContributed Perl DoPlack::Middleware::StackTrace(3)NAMEPlack::Middleware::StackTrace - Displays stack trace when your app dies
SYNOPSIS
enable "StackTrace";
DESCRIPTION
This middleware catches exceptions (run-time errors) happening in your
application and displays nice stack trace screen. The stack trace is
also stored in the environment as a plaintext and HTML under the key
"plack.stacktrace.text" and "plack.stacktrace.html" respectively, so
that middleware futher up the stack can reference it.
This middleware is enabled by default when you run plackup in the
default development mode.
You're recommended to use this middleware during the development and
use Plack::Middleware::HTTPExceptions in the deployment mode as a
replacement, so that all the exceptions thrown from your application
still get caught and rendered as a 500 error response, rather than
crashing the web server.
Catching errors in streaming response is not supported.
CONFIGURATION
force
enable "StackTrace", force => 1;
Force display the stack trace when an error occurs within your
application and the response code from your application is 500.
Defaults to off.
The use case of this option is that when your framework catches all
the exceptions in the main handler and returns all failures in your
code as a normal 500 PSGI error response. In such cases, this
middleware would never have a chance to display errors because it
can't tell if it's an application error or just random "eval" in
your code. This option enforces the middleware to display stack
trace even if it's not the direct error thrown by the application.
no_print_errors
enable "StackTrace", no_print_errors => 1;
Skips printing the text stacktrace to console ("psgi.errors").
Defaults to 0, which means the text version of the stack trace
error is printed to the errors handle, which usually is a standard
error.
