Breaking changes

• ref(tracing): rework tracing to Sentry span name/op conversion (#887) by @lcian
  • The tracing integration now uses the tracing span name as the Sentry span name by default.
  • Before this change, the span name would be set based on the tracing span target (<module>::<function> when using the tracing::instrument macro).
  • The tracing integration now uses <span target>::<span name> as the default Sentry span op (i.e. <module>::<function> when using tracing::instrument).
  • Before this change, the span op would be set based on the tracing span name.
  • Read below to learn how to customize the span name and op.
  • When upgrading, please ensure to adapt any queries, metrics or dashboards to use the new span names/ops.
• ref(tracing): use standard code attributes (#899) by @lcian
  • Logs now carry the attributes code.module.name, code.file.path and code.line.number standardized in OTEL to surface the respective information, in contrast with the previously sent tracing.module_path, tracing.file and tracing.line.
• fix(actix): capture only server errors (#877) by @lcian
  • The Actix integration now properly honors the capture_server_errors option (enabled by default), capturing errors returned by middleware only if they are server errors (HTTP status code 5xx).
  • Previously, if a middleware were to process the request after the Sentry middleware and return an error, our middleware would always capture it and send it to Sentry, regardless if it was a client, server or some other kind of error.
  • With this change, we capture errors returned by middleware only if those errors can be classified as server errors.
  • There is no change in behavior when it comes to errors returned by services, in which case the Sentry middleware only captures server errors exclusively.
• fix: send trace origin correctly (#906) by @lcian
  • TraceContext now has an additional field origin, used to report which integration created a transaction.

Behavioral changes

• feat(tracing): send both breadcrumbs and logs by default (#878) by @lcian
  • If the logs feature flag is enabled, and enable_logs: true is set on your client options, the default Sentry tracing layer now sends logs for all events at or above INFO.

Features

• ref(tracing): rework tracing to Sentry span name/op conversion (#887) by @lcian

  • Additional special fields have been added that allow overriding certain data on the Sentry span:
    • sentry.op: override the Sentry span op.
    • sentry.name: override the Sentry span name.
    • sentry.trace: given a string matching a valid sentry-trace header (sent automatically by client SDKs), continues the distributed trace instead of starting a new one. If the value is not a valid sentry-trace header or a trace is already started, this value is ignored.
  • sentry.op and sentry.name can also be applied retroactively by declaring fields with value tracing::field::Empty and then recorded using tracing::Span::record.
  • Example usage:

    #[tracing::instrument(skip_all, fields(
        sentry.op = "http.server",
        sentry.name = "GET /payments",
        sentry.trace = headers.get("sentry-trace").unwrap_or(&"".to_owned()),
    ))]
    async fn handle_request(headers: std::collections::HashMap<String, String>) {
        // ...
    }

  • Additional attributes are sent along with each span by default:
    • sentry.tracing.target: corresponds to the tracing span's metadata.target()
    • code.module.name, code.file.path, code.line.number

• feat(core): add Response context (#874) by @lcian

  • The Response context can now be attached to events, to include information about HTTP responses such as headers, cookies and status code.
  • Example:

    let mut event = Event::new();
    let response = ResponseContext {
        cookies: Some(r#""csrftoken": "1234567""#.to_owned()),
        headers: Some(headers_map),
        status_code: Some(500),
        body_size: Some(15),
        data: Some("Invalid request"),
    };
    event
        .contexts
        .insert("response".to_owned(), response.into());

Fixes
