that will log the error. My cronjobs normally end up looking like
TaskWrapper('some job') do

and elsewhere
def TaskWrapper
begin
yield
rescue Exception => ex
#do something with the exception
raise
end
end
I use rescue Exception because for once I think it's appropriate that
things like SyntaxError are caught so that I can be notified about them
For the sinatra (or even the rails case) you could write a rack middleware
that would look something like
class ErrorNotifier
def initialize(app)
@app = app
end
def call(env)
begin
@app.call(env)
rescue Exception => ex
#do something with the exception
raise
end
end
end
You could also render an error message if you want to override that.
You might also be interested in the exception handling stuff described
