Breadcrumbs are Unrelated to Issues

[cobyeastwood183]

Problem Statement

The problem seems similar to an older github issue, where the solution relied on sentry-actix for setting up a hub per request for ensuring that requests do not share breadcrumbs.

Continuation of issue.

Solution Brainstorm

I am noticing breadcrumbs hours apart show up in my issues, some seem unrelated, and want to customize how they get grouped. I am looking for an alternative to using sentry-actix middleware, ideally a solution that does not require a provider.

Thanks @cobyeastwood183, I'll look into this.
In the meantime, could we get a small repro sample from the user? That would help.

@lcian, thank you! More details are available in this ticket, https://sentry.zendesk.com/agent/tickets/154533. I will follow up for a repro.

Thanks @cobyeastwood183 ! I've requested zendesk access because I don't have it.

Based on what I see in the ticket, the user is using the middleware in the tracing-actix-web crate to start a tracing root span on every HTTP request.
Then they're using our sentry-tracing layer to convert tracing spans into Sentry spans.

In order to have correct breadcrumbs without using sentry-actix, the user would need to manually manage hubs.
This means they would have to extend the tracing-actix-web middleware to wrap the request-response cycle in something like:

let hub = sentry::Hub::new_from_top(sentry::Hub::current());
sentry::Hub::run(hub, || /* handle the request */);

If any futures are used inside the run call, they also need to bind the hub to the future to ensure the correct hub is used when polling it, as follows:

let res = future.bind_hub(sentry::Hub::current()).await;

This basically replicates the hub management logic that is inside sentry-actix.

I haven't looked into the code for tracing-actix-web too much but it's possible that to accomplish this they would need to fork it.

It was probably my bad to suggest moving away from sentry-actix altogether and just use tracing-actix-web + sentry-tracing in the Discord thread because I didn't think about hub management.

@lcian thank you! Will forward this over.
