# frozen-string-literal: true
module Sequel
module Plugins
# The empty_failure_backtraces plugin uses empty backtraces when raising HookFailed and ValidationFailed
# exceptions. This can be significantly faster, and if you are using these exceptions for
# flow control, you do not need the backtraces. This plugin is about 10% faster on CRuby
# and 10-15x faster on JRuby 9.2.7.0+. This does not have an effect on JRuby <9.2.7.0.
#
# Usage:
#
# # Make all model subclass instances use empty backtraces for HookFailed
# # and ValidationFailed exceptions (called before loading subclasses)
# Sequel::Model.plugin :empty_failure_backtraces
#
# # Make the Album class use empty backtraces for HookFailed and ValidationFailed exceptions
# Album.plugin :empty_failure_backtraces
module EmptyFailureBacktraces
module InstanceMethods
private
# Use empty backtrace for HookFailed exceptions.
def hook_failed_error(msg)
e = super
e.set_backtrace([])
e
end
# Use empty backtrace for ValidationFailed exceptions.
def validation_failed_error
e = super
e.set_backtrace([])
e
end
end
end
