sentry-backtrace

Fixes

• Preserve floating-point fields in tracing logs as numeric attributes (#1278).

Fixes

• Preserve floating-point fields in tracing logs as numeric attributes (#1278).
• Fix a bug that prevented the Curl transport from respecting Sentry rate limits (#1279).

Breaking Changes

• ClientOptions is now #[non_exhaustive] (#1230). The struct must now be constructed with the builder-style setters:

  // Before
  let options = sentry::ClientOptions {
      dsn: "https://[email protected]/0",
      debug: true,
      release: Some("[email protected]".into()),
      ..Default::default()
  };
  
  // After
  let options = sentry::ClientOptions::new()
      .dsn("https://[email protected]/0")
      .debug(true)
      .release("[email protected]");

• Updated the sentry-opentelemetry integration to support OpenTelemetry 0.32. Users of the integration must update their OpenTelemetry dependencies from 0.29 to 0.32 (#1262).

• The logs and metrics features are now enabled by default in the sentry crate. This does not break the API, but may cause new telemetry to be sent to Sentry: log and tracing integrations can send structured logs, and applications can send metrics without adding the feature flags. Disable these features explicitly if this additional telemetry is not desired (#1251).

• Removed the public ClientOptions::sample_rate field. Use ClientOptions::event_sampling_strategy to inspect the configured event sampling strategy, and use the existing ClientOptions::sample_rate(...) builder setter to configure fixed-rate sampling.

• Removed the public ClientOptions::sample_rate field. Use ClientOptions::event_sampling_strategy to inspect the configured event sampling strategy, and use the existing ClientOptions::sample_rate(...) builder setter to configure fixed-rate sampling (#1228).

• Removed the public ClientOptions::traces_sample_rate and ClientOptions::traces_sampler fields. Use ClientOptions::traces_sampling_strategy to inspect the configured traces sampling strategy, and use the existing ClientOptions::traces_sample_rate(...) and ClientOptions::traces_sampler(...) builder setters to configure fixed-rate and callback-based sampling (#1227).

• EnvelopeItem now stores Event and Transaction payloads in Box values. Code that constructs or pattern-matches these variants must account for the additional indirection (#1255).

• The sentry_log::RecordMapping enum's Event now stores the event in a Box (#1269).

• sentry_slog::RecordMapping is now #[non_exhaustive] and the Event variant now stores a boxed Event<'static> (#1270)

• The sentry_tracing::EventMapping enum's Event variant is now stored in a Box (#1272)

New Features

• Added TracePropagationContext as the preferred type for Sentry trace propagation metadata. The existing SentryTrace type remains available for backwards compatibility (#1212).
• Added Dsn::org_id, which parses the Sentry SaaS organization ID from DSN hosts such as o123.ingest.sentry.io (#1202).
• Added ClientOptions::org_id and ClientOptions::strict_trace_continuation (#1203). These options control how traces are continued and can help prevent traces from third-party services, which happen to be instrumented with Sentry, from being continued.

Improvements

• Improved trace continuation safety by rejecting incoming traces with incompatible sentry-org_id values when starting transactions, according to strict trace continuation rules (#1218).

Fixes

• Restored the reqwest transport's pre-0.13 protocol features by disabling HTTP/2 and native-TLS ALPN (#1258).
• EnvelopeError is now #[non_exhaustive] to allow adding new error variants without a breaking change (#1254).

The Sentry Rust SDK now reports data discarded by the SDK to Sentry’s Stats page. The SDK reports approximate counts for drops from transports, queues, rate-limit backoff, sampling, event processors, and before_send* callbacks, including span counts for dropped transactions and byte counts for dropped logs and metrics.

New Features

• Added EnvelopeFilter and EnvelopeFilterCallbacks, which let callers observe envelope items removed by Envelope::filter, including attachments removed after their event or transaction is filtered out. Existing Envelope::filter closure callers continue to work, although some closures may require an explicit item type annotation (#1182).
• Added the LossSource trait, which provides the client report data categories and quantities to report when supported Sentry data is dropped (#1170).
• Added TransportFactory::create_transport_with_options, which constructs transports from TransportOptions instead of full ClientOptions (#1142).
• Added transport-specific options types and with_options constructors for built-in HTTP transports, including ReqwestHttpTransportOptions, CurlHttpTransportOptions, UreqHttpTransportOptions, and EmbeddedSVCHttpTransportOptions (#1142).
• Added transport worker options types and deprecated the legacy constructors for built-in background transport workers, including StdTransportThreadOptions and TokioTransportThreadOptions (#1142).
• Added client report protocol types in sentry-types, including ClientReport, client_report::Item, client_report::Category, and client_report::Reason, plus support for serializing client_report envelope items (#1144).
• Added a client report Recorder type, which modern TransportFactory implementations receive via TransportOptions. Transports can use this recorder to record discarded Sentry data; the SDK aggregates these reported losses and automatically sends them in a future envelope (#1158).

Deprecations

• Deprecated Hub::with. Use Hub::current instead (#1126).

Fixes

• Fixed ureq transport handling for HTTP error statuses so 429 rate limits and 413 payload-too-large responses are processed correctly (#1177).

Behavior Changes

• Custom transport factories that implement TransportFactory::create_transport now receive ClientOptions reconstructed from TransportOptions. The reconstructed options include only transport-relevant fields, such as DSN, user agent, proxy settings, and TLS certificate validation settings. This may affect code that reads non-transport fields in create_transport, but the API remains source-compatible and this change is included in a minor/patch release (#1142).

Fixes

• Changed ClientOptions::enable_metrics to default to true, aligning metrics behavior with other Sentry SDKs (#1106). Metric capture APIs still require the metrics feature flag at compile time.

Breaking Changes

• Added the following metrics-related fields to the ClientOptions struct in sentry-core. Both fields are no-ops, unless the metrics feature flag is enabled:
  • enable_metrics, used to enable sending metrics to Sentry (#1073).
  • before_send_metric, used to define a callback for filtering/pre-processing metrics before sending to Sentry (#1064).
• There are several breakages related to the SemVer feature additivity bug fixes:
  • sentry_core::ClientOptions fields before_send_log, enable_logs, auto_session_tracking, and session_mode are no longer gated behind the logs and release-health feature flags (#1091). Code that constructs ClientOptions with a full struct literal (without ..Default::default()), or which exhaustively matches against it, must now include all four fields regardless of enabled features.
  • sentry_core::Scope can no longer be publicly constructed or exhaustively matched against, even when the client feature is disabled (#1094). Previously, both of these were possible when client was disabled.
  • sentry_core::Scope::add_event_processor now requires passed closures to be RefUnwindSafe (#1093). Thanks to this change, sentry_core::Scope is now UnwindSafe regardless of feature flag configuration; previously, Scope was only UnwindSafe when the client feature was disabled.
  • sentry_tracing::EventMapping is now #[non_exhaustive] (#1097).
  • sentry_log::RecordMapping is now #[non_exhaustive] (#1098).

New Features

📊📈💯 The Sentry-Rust SDK now supports emitting Sentry Metrics (#1073)!

To get started, you will need to add the metrics feature flag when compiling the sentry crate. You will also need to enable metrics when initializing the SDK, like so:

use sentry::ClientOptions;

let _guard = sentry::init((
    "(your DSN here)",
    ClientOptions {
        enable_metrics: true,
        // ... other options ...
        ..Default::default()
    },
));

You can then capture metrics as follows:

use sentry::metrics;
use sentry::types::protocol::latest::Unit;

// We support counter, gauge, and distribution metrics.
metrics::counter("example.counter", 1).capture();
metrics::gauge("connections", 20).capture();
metrics::distribution("response.time", 123.4)
    .unit(Unit::Millisecond) // units can also be set on gauges
    .attribute("http.status", 200) // attributes can be set on all metric types
    .capture();

Fixes

• Fixed several feature additivity SemVer violations, where enabling a feature flag could have introduced breaking changes. All known violations are fixed now, so simply enabling an additional feature flag in any Sentry SDK crate should no longer cause any public API breakages. Fixing these issues required us to break the public API in some places; those breakages are detailed above.

Breaking Changes

• Update reqwest from 0.12.25 to 0.13.1 (#998). This change is breaking for users who use the RequestHttpTransport::with_client method.
• sentry_core::HubSwitchGuard is now !Send, preventing it from being moved across threads (#957).

New Features

• Added a Envelope::into_items method, which returns an iterator over owned EnvelopeItems in the Envelope (#983).
• Expose transport utilities (#949)

Fixes

• Fixed thread corruption bug where HubSwitchGuard could be dropped on wrong thread (#957).
• We now fork the Hub every time a span is entered. This prevents data from leaking across spans (#957).

New Features

• Log HTTP 413 responses as oversized envelope discards in HTTP transports (#966)

Minimum Supported Rust Version

• Bump minimum supported Rust version to 1.88 (#970).

Improvements

• Make it possible to == Transaction/Span/TransactionOrSpan (#942)

Dependencies

• Update reqwest from 0.12.15 to 0.12.25 (#951)

Breaking changes

• Removed the ClientOptions struct's trim_backtraces and extra_border_frames fields (#925).
  • These fields configured backtrace trimming, which is being removed in this release.

Improvements

• Removed backtrace trimming to align the Rust SDK with the general principle that Sentry SDKs should only truncate telemetry data when needed to comply with documented size limits (#925). This change ensures that as much data as possible remains available for debugging.
  • If you notice any new issues being created for existing errors after this change, please open an issue on GitHub.

Fixes

• fix: adjust sentry.origin for log integration (#919) by @lcian

Breaking changes

• Add custom variant to AttachmentType that holds an arbitrary String. (#916)

Breaking changes

• feat(log): support combined LogFilters and RecordMappings (#914) by @lcian
  • Breaking change: sentry::integrations::log::LogFilter has been changed to a bitflags struct.
  • It's now possible to map a log record to multiple items in Sentry by combining multiple log filters in the filter, e.g. log::Level::ERROR => LogFilter::Event | LogFilter::Log.
  • If using a custom mapper instead, it's possible to return a Vec<sentry::integrations::log::RecordMapping> to map a log record to multiple items in Sentry.

Behavioral changes

• ref(log): send logs by default when logs feature flag is enabled (#915) by @lcian
  • If the logs feature flag is enabled, the default Sentry log logger now sends logs for all events at or above INFO.
• ref(logs): enable logs by default if logs feature flag is used (#910) by @lcian
  • This changes the default value of sentry::ClientOptions::enable_logs to true.
  • This simplifies the setup of Sentry structured logs by requiring users to just add the log feature flag to the sentry dependency to opt-in to sending logs.
  • When the log feature flag is enabled, the tracing and log integrations will send structured logs to Sentry for all logs/events at or above INFO level by default.

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

• build(panic): Fix build without other dependencies (#883) by @liskin
  • The sentry-panic crate now builds successfully when used as a standalone dependency.
• fix(transport): add rate limits for logs (#894) by @giortzisg

Features

• feat(log): support kv feature of log (#851) by @lcian
  • Attributes added to a log record using the kv feature are now recorded as attributes on the log sent to Sentry.
• feat(types): add all the missing supported envelope headers (#867) by @lcian
• feat(types): add setters for envelope headers (#868) by @lcian
  • It's now possible to set all of the envelope headers supported by the protocol when constructing envelopes.
• feat(core): add some DSC fields to transaction envelope headers (#869) by @lcian
  • The SDK now sends additional envelope headers with transactions. This should solve some extrapolation issues for span metrics.

Behavioral changes

• feat: filter username and password in URLs (#864) by @lcian
  • Usernames and passwords that could be contained in URLs captured when using the Actix Web or axum integration are now always filtered out.
  • If the Request is created manually by the user, then these fields are not filtered out.
  • This information was already filtered by Relay, but should also be filtered by the SDK itself as a first line of defense.

Fixes

• docs: match description of debug option with behavior since PR #820 (#860) by @AlexTMjugador

Breaking changes

• feat(tracing): support combined EventFilters and EventMappings (#847) by @lcian
  • EventFilter has been changed to a bitflags struct.
  • It's now possible to map a tracing event to multiple items in Sentry by combining multiple event filters in the event_filter, e.g. tracing::Level::ERROR => EventFilter::Event | EventFilter::Log.
  • It's also possible to use EventMapping::Combined to map a tracing event to multiple items in Sentry.
  • ctx in the signatures of event_from_event, breadcrumb_from_event and log_from_event has been changed to take impl Into<Option<&'context Context<'context, S>>> to avoid cloning the Context when mapping to multiple items.

Features

• feat(core): emit debug log when calling capture_log but logs are disabled (#849) by @lcian

Fixes

• fix(logs): stringify u64 attributes greater than i64::MAX (#846) by @lcian

Dependencies

• chore(deps): bump anyhow and disable its backtrace feature (#632) by @LunaBorowska

Breaking changes

• refactor(logs): apply user attributes to log regardless of send_default_pii (#843) by @lcian
  • User attributes should be applied to logs regardless of send_default_pii. Therefore, that parameter was removed from sentry_core::Scope::apply_to_log.

Features

• feat(tracing): add support for logs (#840) by @lcian
  • To capture tracing events as Sentry structured logs, enable the logs feature of the sentry crate.
  • Then, initialize the SDK with enable_logs: true in your client options.
  • Finally, set up a custom event filter to map events to logs based on criteria such as severity. For example:

      let sentry_layer = sentry_tracing::layer().event_filter(|md| match *md.level() {
          tracing::Level::ERROR => EventFilter::Event,
          tracing::Level::TRACE => EventFilter::Ignore,
          _ => EventFilter::Log,
      });
  

• feat(log): add support for logs (#841) by @lcian
  • To capture log records as Sentry structured logs, enable the logs feature of the sentry crate.
  • Then, initialize the SDK with enable_logs: true in your client options.
  • Finally, set up a custom event filter to map records to Sentry logs based on criteria such as severity. For example:

      let logger = sentry::integrations::log::SentryLogger::new().filter(|md| match md.level() {
          log::Level::Error => LogFilter::Event,
          log::Level::Trace => LogFilter::Ignore,
          _ => LogFilter::Log,
      });
  

• refactor(logs): cache default attributes and add OS attributes (#842) by @lcian
  • os.name and os.version are now being attached to logs as default attributes.

Fixes

• fix(logs): send environment in sentry.environment default attribute (#837) by @lcian

Behavioral changes

• refactor(tracing): refactor internal code and improve docs (#839) by @lcian
  • Errors carried by breadcrumbs will now be stored in the breadcrumb data under their original field name.
  • Before, they were all stored under a single key called errors.

Dependencies

• chore(deps): upgrade ureq to 3.x (#835) by @algesten

Features

Support for Sentry structured logs has been added to the SDK.

• To set up logs, enable the logs feature of the sentry crate and set enable_logs to true in your client options.

• Then, use the logger_trace!, logger_debug!, logger_info!, logger_warn!, logger_error! and logger_fatal! macros to capture logs.

• To filter or update logs before they are sent, you can use the before_send_log client option.

• Please note that breaking changes could occur until the API is finalized.

• feat(logs): add log protocol types (#821) by @lcian

• feat(logs): add ability to capture and send logs (#823) by @lcian & @Swatinem

• feat(logs): add macro-based API (#827) by @lcian & @szokeasaurusrex

• feat(logs): send logs in batches (#831) by @lcian

Behavioral changes

• feat(core): implement Tracing without Performance (#811) by @lcian
  • The SDK now implements Tracing without Performance, which makes it so that each Scope is associated with an object holding some tracing information.
  • This information is used as a fallback when capturing an event with tracing disabled or otherwise no ongoing span, to still allow related events to be linked by a trace.
  • A new API Scope::iter_trace_propagation_headers has been provided that will use the fallback tracing information if there is no current Span on the Scope.

Breaking changes

• refactor: remove debug-logs feature (#820) by @lcian
  • The deprecated debug-logs feature of the sentry crate, used for the SDK's own internal logging, has been removed.

Fixes

• build: include sentry-actix optionally when release-health is enabled (#806) by @lcian
  • sentry-actix is now being included as a dependency only when explicitly added, either as a direct dependency or through the actix feature flag of the sentry crate.
  • Due to a mistake in the Cargo.toml, it was previously being included as a dependency by default when using just the sentry crate with default features.

OpenTelemetry integration

An OpenTelemetry integration has been released. Please refer to the changelog entry below for the details.

Breaking changes

• refactor(tracing): remove EventFilter::exception and always attach exception (#768) by @lcian
  • The EventFilter::Exception enum variant has been removed. Please use EventFilter::Event instead to achieve the same behavior.
  • Using EventFilter::Event will always attach any error struct used within the error field passed to the tracing macro, as EventFilter::Exception did previously.
  • The error field will also be attached to breadcrumbs as an errors field resembling the structure of Sentry events created from error structs.
• fix: use release-health flag in sentry-actix and remove it from subcrates where unneeded (#787) by @lcian
  • As a follow-up from the changes in the previous release, the ClientOptions fields auto_session_tracking and session_mode are now gated behind the release-health feature flag of the sentry crate.
  • If you depend on sentry with default-features = false, you need to include the release-health feature flag to benefit from the Release Health features of Sentry and have access to the aforementioned client options.
  • The release-health feature flag is used correctly in sentry-actix to enable compilation of that subcrate when it's disabled.
  • The release-health has been removed from the sentry-tracing and sentry-tower subcrates, where it was unnecessary.
• refactor: remove Surf transport (#766) by @lcian
  • The Surf transport has been removed as the surf crate is unmaintained and it was holding back dependency upgrades.
  • If you really want to still use Surf, you can define a custom TransportFactory and pass it as the transport in your ClientOptions

Behavioral changes

• refactor: honor send_default_pii in sentry-actix and sentry-tower (#771) by @lcian
  • The client option send_default_pii (disabled by default) is now honored by sentry-actix and sentry-tower.
  • This means that potentially sensitive headers such as authorization, cookies, and those that usually contain the user's IP address are filtered and not sent to Sentry.
  • If you want to get back to the previous behavior and capture all headers, please set send_default_pii to true in your ClientOptions.
  • Please refer to our Data Collected page for a comprehensive view of the data collected by the SDK.
• refactor(debug-images): force init DEBUG_META on integration init (#773) by @lcian
  • The DebugImages integration has been updated to init the DEBUG_META Lazy immediately.
  • Using this integration is known to cause issues in specific versions of the Linux kernel due to issues in a library it depends on.
  • Previously, on problematic systems the SDK would cause deadlock after capturing the first event. Now the SDK will panic on initialization instead. Please open an issue if you're affected.

Features

• feat(otel): add OpenTelemetry SpanProcessor, Propagator, Extractor (#779) by @lcian
  • A new integration for the opentelemetry crate has been released.
  • It can be used to capture spans created using the opentelemetry API and send them to Sentry.
  • Distributed tracing is also supported, provided that the upstream/downstream services support the Sentry or W3C distributed tracing metadata format.
  • Please refer to the subcrate's README or the crate docs to see an example of setup and usage.
• feat: expose sentry-actix as a feature of sentry (#788) by @lcian
  • sentry-actix is now exposed by the sentry crate as sentry::integrations::actix, gated behind the actix feature flag.
  • Please update your dependencies to not depend on the sentry-actix subcrate directly.

Dependencies

  • The minimum supported Rust version has been raised to 1.81.
• feat(core): introduce release-health feature (#749) by @pepperoni505
  • A new release-health feature flag was introduced that gates the Release Health features of Sentry.
  • This allows for compilation of the SDK on certain WASM targets.
  • Release Health features were already present and enabled with no feature flag in previous versions.
  • The new feature flag will be enabled by default when using sentry, sentry-actix, sentry-tower or sentry-tracing with the default features.
  • If you're fine-tuning your feature flags, make sure to enable release-health to get back the previous behavior.
• ref(metrics): remove features and code related to the old metrics beta (#740) by @lcian
  • The metrics feature and the code related to it has been removed from the crate, as the Sentry backend stopped ingesting metrics a while ago.
• Switch to MIT license (#724) by @cleptric
  • The license for the crates has been changed to MIT.

Features

• feat(actix): capture HTTP request body (#731) by @pacifistes
  • The middleware for actix-web now supports capturing and attaching the request body to HTTP request transactions.
  • You need to enable send_default_pii in your client options for this to be enabled, and you can fine-tune the behavior using the new option max_request_body_size.
• feat(core): transaction.set_data sets data on TraceContext (#739) by @lcian
  • transaction.set_data now sets data on TraceContext, as the SDK should not use the extra field.
• ref(backtrace): add entries and extra logic for in-app detection (#756) by @lcian
• feat(core): add more frames to be considered not in_app (#760) by @lcian
  • The logic used by the SDK to detect in-app stack frames has been improved. Now the SDK will mark more frames as not in-app.
  • A similar improvement has been added to the Sentry backend so that old versions of the SDK can benefit from improved in-app reporting.

Fixes

• fix(http): Finish transaction on drop (#727) by @Dav1dde
  • Fixed a bug where the current transaction was not finished (hence not sent to Sentry) when its corresponding future was dropped, e.g. due to a panic.
• follow https://github.com/getsentry/sentry-rust/pull/439 for actix-web. fix https://github.com/getsentry/sentry-rust/issues/680 (#737) by @pavel-rosputko
  • The HTTP request metadata is now being correctly attached to transactions when using sentry-actix.
• fix(tracing): wrap error with synthetic mechanism only if attaching stacktrace (#755) by @lcian
  • Fixed a bug that should result in improved grouping and issue titles for events reported by sentry-tracing when not capturing stack traces.
• fix(actix): process request in other middleware using correct Hub (#758) by @lcian
  • The subsequent middleware in the chain when processing a request now execute within the correct Hub.
• fix(anyhow): attach stacktrace only if error provides backtrace (#759) by @lcian
  • Fixed a bug where the SDK was providing incorrect stack traces when capturing an anyhow when the backtrace feature is enabled but RUST_BACKTRACE is not set.
  • This should result in correct grouping of the affected issues.

• The deprecated error-chain and failure integrations, features and crates were removed.

Features:

• The slog integration now supports capturing slog::KV pairs for both breadcrumbs and events.
• Preliminary support for attachments was added to sentry-types and the Envelope. However, deeper integration into the SDK is not yet complete.

Fixes:

• Fix regression defaulting ClientOptions::environment from SENTRY_ENVIRONMENT.
• The debug-images integration now captures the correct image_addr.
• Do not send invalid exception events in the log and slog integrations. Both integrations no longer attach the location. To receive location information, set options.attach_stacktrace to true.
• Process all event backtraces the same way.
• Fix a panic in the session flusher.

Updates:

• Updated reqwest to version 0.11, which is based on tokio 1.

Thank you:

Features, fixes and improvements in this release have been contributed by:

• @jrobsonchase
• @Jake-Shadle

Breaking Changes:

• Bump the minimum required Rust version to 1.42.0.
• The actix integration / middleware is now compatible with actix-web 3.
• Removed all deprecated exports and deprecated feature flags.
• The failure integration / feature is now off-by-default along with its deprecation.
• The log and slog integrations were re-designed, they now offer types that wrap a log::Log or slog::Drain and forward log events to the currently active sentry Hub based on an optional filter and an optional mapper.
• The new log integration will not implicitly call log::set_max_level_filter anymore, and users need to do so manually.

Features:

• The SDK will now set a default environment based on debug_assertions.
• Session updates are now sent lazily.
• Add the new end_session_with_status global and Hub functions which allow ending a Release Health Session with an explicit SessionStatus.

Deprecations:

• The error-chain and failure integration was officially deprecated and will be removed soon.

Fixes:

• Fixed a deadlock when nesting configure_scope calls.
• Improved transport shutdown logic and fixed a potential deadlock on shutdown.

Highlights:

• The Rust SDK now has experimental support for Release Health Sessions using the start_session and end_session API (global and on the Hub).

Breaking Changes:

Thank you:

Features, fixes and improvements in this release have been contributed by:

• @Jake-Shadle
• @maxcountryman
• @ErichDonGubler
• @nCrazed
• @jrconlin

Fixes:

• Better deal with concurrent Hub access.

Highlights:

The sentry crate has been split up into a sentry-core, and many smaller per-integration crates. Application users should continue using the sentry crate, but library users and integration/transport authors are encouraged to use the sentry-core crate instead.

Additionally, sentry can now be extended via Integrations.

Breaking Changes:

• The utils module has been removed, and most utils have been moved into integrations.
• The integrations module was completely rewritten.
• When constructing a Client using a ClientOptions struct manually, it does not have any default integrations, and it does not resolve default options from environment variables any more. Please use the explicit apply_defaults function instead. The init function will automatically call apply_defaults.
• The init function can’t be called with a Client anymore.

Features:

• Sentry can now capture std::error::Error types, using the capture_error and Hub::capture_error functions, and an additional event_from_error utility function.
• Sentry now has built-in support to bind a Hub to a Future.
• Sentry can now be extended with Integrations.
• The ClientInitGuard, Future and ScopeGuard structs and apply_defaults, capture_error, event_from_error, with_integration and parse_type_from_debug functions have been added to the root exports.
• The FutureExt, Integration, IntoBreadcrumbs, IntoDsn, Transport and TransportFactory traits are now exported.
• The types module now re-exports sentry-types.

Deprecations:

• The internals module is deprecated. Please use items from the crate root or the types module instead.
• All the feature flags have been renamed, the old names are still available but will be removed in the future.
