First one is related to `OpenTelemetry.Ctx` API. I've noticed in a few
scenarios the current span of a trace may get lost after Ecto calls.
Looking at the The `attach/1` typespec, it's a Ctx -> Token, while
`dettach/1` as Token -> Ctx function. That made me assume the expected
input of dettach is the return type of attach. Indeed, after this change
we got the behavior of Ecto calls preserve the parent span untouched.
That leads to a second bug found. When ecto does simple calls within a
Task, due the special propagation code for preloads that means it will
skip the current span, if any. The solution here is to first check the
current process.
One test was added to reproduce this bug.
Default exporter immediately attempts on start connect to
`:otel-collector` default port. As we don't have any collector running
on our test environment, this results in a few warnings. That's not an
issue in itself, as code immediately switches to another export, but
creates a lot of noise.
This patch moves the exporter setup to `config/test.exs`, essentially
removing the need to restart opentelemetry applicationn for each test
case. The only work setup blocks do is update the exporter's target pid.
The processor was changed to simple mode, available now, which also remove
another vector of (unlikely but theoretically possible) race-conditions.
* Set error status on error instead of just adding attribute
* Use Exception.message if error is an exception
