Add set_customdata to RaygunSender, apply process level custom data w…

[turtlespin]

Overview

This PR adds the concept of custom data which can be set once against a RaygunSender instance and then applied to each exception which is raised through that sender. This avoids the requirement to specify custom data with each invocation of send_exception.

A new method set_customdata has been added to RaygunSender to allow this to be specified.

Examples

Setup

client = raygunprovider.RaygunSender('YOUR_API_KEY')

Initialize a client instance

client.set_customdata({'key':'value','foo':'bar'})

Use the new set_customdata method to apply the custom data Dict at a sender level

Example 1

client.send_exception(exc_info=(exc_type, exc_value, exc_traceback))

Raising an exception with no custom data specified

The resulting error has the sender level custom data applied

Example 2

client.send_exception(exc_info=(exc_type, exc_value, exc_traceback), userCustomData={'baz':'value','elden':'ring'})

Raising an exception with custom data specified

The resulting error has both the sender level custom data and the instance level custom data

Example 3

client.send_exception(exc_info=(exc_type, exc_value, exc_traceback), userCustomData={'key':'elden','foo2':'ring'})

Raising an exception with custom data specified where some keys are the same as the sender level

The resulting error has both the sender level custom data and the instance level custom data but where keys are the same the instance level is used in preference
