Breadcrumb category handling

[semuserable]

We don't assign categories for breadcrumbs from Unity. It means that if user tries to use options.BeforeBreadcrumb based on the docs (Customize Breadcrumbs section) then he/she might find a non-expected behaviour.

Not expected stuff based on current docs

• categories which are null displayed as generic on web UI, if the user tries to configure Sentry like this...

  SentryUnity.Init(options =>
  {
  options.Enabled = true;
  options.Dsn = "<MY_DSN>";
  options.BeforeBreadcrumb = breadcrumb => breadcrumb.Category == "generic" ? null : breadcrumb;
  });

  ... events won't be ignored on web UI, because .NET side doesn't set category to generic

• exception breadcrumbs are also ignored by options.BeforeBreadcrumb API

What needs to be done

• Assign categories for normal breadcrumbs. We need to come up with a list of possible categories for all .AddBreadcrumb calls

We don't assign categories for breadcrumbs from Unity.

We should set a category such as unity.logger

generic is set by Sentry if the SDK didn't send any.

Also we can just change the docs to show a different use case for BeforeBreadcrumb such as:

    options.BeforeBreadcrumb = breadcrumb => breadcrumb.Message?.StartsWith("bad crumb") ? null : breadcrumb;

Do you want to add _hub.AddBreadcrumb functionality into UnityLogger?

Also, we have 2 _hub.AddBreadcrumb calls in UnityApplicationLoggingIntegration.OnLogMessageReceived,

one for "normal breadcrumb"

and another for "special breadcrumb"

What categories should be assigned here?

I believe the same category is fine.
