# Exceptions
|
|
|
|
Exceptions in LBRY are defined and generated from the Markdown table at the end of this README.
|
|
|
|
## Guidelines
|
|
|
|
When possible, use [built-in Python exceptions](https://docs.python.org/3/library/exceptions.html) or `aiohttp` [general client](https://docs.aiohttp.org/en/latest/client_reference.html#client-exceptions) / [HTTP](https://docs.aiohttp.org/en/latest/web_exceptions.html) exceptions, unless:
|
|
1. You want to provide a better error message (extend the closest built-in/`aiohttp` exception in this case).
|
|
2. You need to represent a new situation.
|
|
|
|
When defining your own exceptions, consider:
|
|
1. Extending a built-in Python or `aiohttp` exception.
|
|
2. Using contextual variables in the error message.
|
|
|
|
## Table Column Definitions
|
|
|
|
Column | Meaning
|
|
---|---
|
|
Code | Codes are used only to define the hierarchy of exceptions and do not end up in the generated output, it is okay to re-number things as necessary at anytime to achieve the desired hierarchy.
|
|
Name | Becomes the class name of the exception with "Error" appended to the end. Changing names of existing exceptions makes the API backwards incompatible. When extending other exceptions you must specify the full class name, manually adding "Error" as necessary (if extending another SDK exception).
|
|
Message | User friendly error message explaining the exceptional event. Supports Python formatted strings: any variables used in the string will be generated as arguments in the `__init__` method. Use `--` to provide a doc string after the error message to be added to the class definition.
