If span is found in current context, I believe you'll have to set the current context as the parent. Currently, ctx would be None.

Done.
I think it was passing earlier as tracer.start_span() makes current span as parent if context passed is none.
@lzchen Should we set parent explicitly for readability or let start_span() handle it?

Oh yes you are correct. Either way is fine with me.

Added this as django.conf.urls.url() is removed in django 4.0. leading to lint check failure (release notes).

The title says flask but contains code for Django. |
Added them to pass lint checks. Just saw those changes have already been merged to master. Removed the django related code. |

Description
Adds support to make spans as INTERNAL if a span is already present in current context in flask.
Fixes #446
Type of change
Please delete options that are not relevant.
Currently flask only makes SERVER spans. With this PR it can make INTERNAL spans in presence of a span in current context.
How Has This Been Tested?
Added unit test for the changes.
Manually tested the scenario.
To reproduce the issue: Add two instrumentors i.e. FlaskInstrumentor and OpenTelemetryMiddleware in the same app. This creates two separate traces instead of one.
