Exception traceback fails due to subsequent exceptions when using the Jinja template backend and Jinja>=2.10.2

Reported by: Barak Shohat Owned by: nobody
Component: Template system Version: 2.2
Severity: Normal Keywords:
Cc: Barak Shohat Triage Stage: Unreviewed

Description

Jinja 2.10.2 introduces a new traceback system per their release docs:

Version 2.10.2 Released 2019-10-04

  • Use Python 3.7’s better traceback support to avoid a core dump when using debug builds of Python 3.7.

This appears to cause source code lines to be incorrectly reported in some template tracebacks, causing errors like the following:

SAMPLE TEMPLATE:

{% extends 'accounts/base.html' %}
{% block accounts_content %}
  {% block password_reset %}
    <form method="post">
      {{ block.super }}               {# ERROR IS HERE - `block` is not defined #}
      {{ crispy(form) }}
      <input class="btn btn-primary" type="submit" name="submit" value="Reset Password">
    </form>
  {% endblock %}
{% endblock %}
