View Source Credo.Check.Warning.RaiseInsideRescue (Credo v1.7.2-rc.4)
This check has a base priority of 0
and works with any version of Elixir.
Explanation
Using Kernel.raise
inside of a rescue
block creates a new stacktrace.
Most of the time, this is not what you want to do since it obscures the cause of the original error.
Example:
# preferred
try do
raise "oops"
rescue
error ->
Logger.warn("An exception has occurred")
reraise error, System.stacktrace
end
# NOT preferred
try do
raise "oops"
rescue
error ->
Logger.warn("An exception has occurred")
raise error
end
