The auto-instrumentation for Python (per OTEP 0001) instruments each library in a separately installable package to ensure users only need to install the libraries that make sense for their use-case. This repository contains the code initially donated by DataDog in the reference folder. All instrumentation that has been ported lives in the instrumentation directory.

The steps below describe the process to port integrations from the reference directory containing the originally donated code to OpenTelemetry.

1. Move the code into the instrumentation directory

mkdir -p instrumentation/opentelemetry-instrumentation-jinja2/src/opentelemetry/instrumentation/jinja2
git mv reference/ddtrace/contrib/jinja2 instrumentation/opentelemetry-instrumentation-jinja2/src/opentelemetry/instrumentation/jinja2

2. Move the tests

git mv reference/tests/contrib/jinja2 instrumentation/opentelemetry-instrumentation-jinja2/tests

3. Add README.rst, setup.cfg and setup.py files and update them accordingly

cp _template/* instrumentation/opentelemetry-instrumentation-jinja2/

4. Add version.py file and update it accordingly

mv instrumentation/opentelemetry-instrumentation-jinja2/version.py instrumentation/opentelemetry-instrumentation-jinja2/src/opentelemetry/instrumentation/jinja2/version.py

5. Fix relative import paths to using ddtrace package instead of using relative paths
6. Update the code and tests to use the OpenTelemetry API
