tracing-core 0.1.30

This release of tracing-core adds a new on_register_dispatch method to the
Subscriber trait to allow the Subscriber to perform initialization after
being registered as a Dispatch, and a WeakDispatch type to allow a
Subscriber to store its own Dispatch without creating reference count
cycles.

Added

• Subscriber::on_register_dispatch method (#2269)
• WeakDispatch type and Dispatch::downgrade() function (#2293)

Thanks to @jswrenn for contributing to this release!

tracing-attributes 0.1.23

This release of tracing-attributes fixes a bug where compiler diagnostic spans
for type errors in #[instrument]ed async fns have the location of the
#[instrument] attribute rather than the location of the actual error, and a
bug where inner attributes in #[instrument]ed functions would cause a compiler
error.

Fixed

• Fix incorrect handling of inner attributes in #[instrument]ed functions (#2307)
• Add fake return to improve spans generated for type errors in async fns (#2270)
• Updated syn dependency to fix compilation with -Z minimal-versions
  (#2246)

Thanks to new contributors @compiler-errors and @e-nomem, as well as @CAD97, for
contributing to this release!

tracing 0.1.37

This release of tracing incorporates changes from tracing-core
v0.1.30 and tracing-attributes v0.1.23,
including the new Subscriber::on_register_dispatch method for performing late
initialization after a Subscriber is registered as a Dispatch, and bugfixes
for the #[instrument] attribute. Additionally, it fixes instances of the
bare_trait_objects lint, which is now a warning on tracing's MSRV and will
become an error in the next edition.

Fixed

• attributes: Incorrect handling of inner attributes in #[instrument]ed
  functions (#2307)
• attributes: Incorrect location of compiler diagnostic spans generated for
  type errors in #[instrument]ed async fns (#2270)
• attributes: Updated syn dependency to fix compilation with -Z minimal-versions (#2246)
• bare_trait_objects warning in valueset! macro expansion (#2308)

Added

• core: Subscriber::on_register_dispatch method (#2269)
• core: WeakDispatch type and Dispatch::downgrade() function (#2293)

Changed

• tracing-core: updated to 0.1.30
• tracing-attributes: updated to 0.1.23

Documented

• Added tracing-web and reqwest-tracing to related crates (#2283,
  #2331)

Thanks to new contributors @compiler-errors, @e-nomem, @WorldSEnder, @Xiami2012,
and @tl-rodrigo-gryzinski, as well as @jswrenn and @CAD97, for contributing to
this release!

• PartialEq and Eq implementations for FieldSet (#2229)

Fixed

• Fixed unhelpful fmt::Debug output for dispatcher::SetGlobalDefaultError
  (#2250)

This release adds support for owned values and fat pointers as arguments to the
Span::record method, as well as updating the minimum tracing-core version
and several documentation improvements.

Fixed

• Incorrect docs in dispatcher::set_default (#2220)
• Compilation with -Z minimal-versions (#2246)

Added

• Support for owned values and fat pointers in Span::record (#2212)
• Documentation improvements (#2208, #2163)

Changed

• tracing-core: updated to 0.1.29

release!

tracing-subscriber 0.3.15

This release fixes a bug where the reload layer would fail to pass through
max_level_hint to the underlying layer, potentially breaking filtering.

Fixed

• reload: pass through max_level_hint to the inner Layer (#2204)

Thanks to @guswynn for contributing to this release!

tracing-subscriber 0.3.14

This release fixes multiple filtering bugs in the Layer implementations for
Option<impl Layer> and Vec<impl Layer>.

Fixed

• layer: Layer::event_enabled implementation for Option<impl Layer<S>>
  returning false when the Option is None, disabling all events globally
  (#2193)
• layer: Layer::max_level_hint implementation for Option<impl Layer<S>>
  incorrectly disabling max level filtering when the option is None (#2195)
• layer: Layer::max_level_hint implementation for Vec<impl Layer<S>>
  returning LevelFilter::ERROR rather than LevelFilter::OFF when the Vec
  is empty (#2195)

Thanks to @CAD97 and @guswynn for contributing to this release!

tracing-opentelemetry 0.17.4

This release adds optional support for recording std::error::Errors using
[OpenTelemetry's semantic conventions for exceptions][exn-semconv].

Added

• Layer::with_exception_fields to enable emitting exception.message and
  exception.backtrace semantic-convention fields when an Error is recorded
  as a span or event field (#2135)
• Layer::with_exception_field_propagation to enable setting exception.message and
  exception.backtrace semantic-convention fields on the current span when an
  event with an Error field is recorded (#2135)

Thanks to @lilymara-onesignal for contributing to this release!

tracing-attributes 0.1.22

This release fixes an issue where using the err or ret arguments to
#[instrument] along with an overridden target, such as

#[instrument(target = "...", err, ret)]

would not propagate the overridden target to the events generated for
errors/return values.

Fixed

• Error and return value events generated by #[instrument(err)] or
  #[instrument(ret)] not inheriting an overridden target (#2184)
• Incorrect default level in documentation (#2119)

Thanks to new contributor @tbraun96 for contributing to this release!
