tracing-subscriber 0.3.5

This release re-enables RUST_LOG filtering in tracing_subscriber::fmt's
default initialization methods, and adds an OffsetLocalTime formatter for
using local timestamps with the time crate.

Added

• fmt: Added OffsetLocalTime formatter to fmt::time for formatting local
  timestamps with a fixed offset (#1772)

Fixed

• fmt: Added a Targets filter to fmt::init() and fmt::try_init() when
  the "env-filter" feature is disabled, so that RUST_LOG is still honored
  (#1781)

Thanks to @marienz and @ishitatsuyuki for contributing to this release!

tracing-journald 0.2.1

This release improves how tracing-journald communicates with journald,
including the handling of large payloads.

Added

• Use an unconnected socket, so that logging can resume after a journald
  restart (#1758)

Fixed

• Fixed string values being written using fmt::Debug (#1714)
• Fixed EMSGSIZE when log entries exceed a certain size (#1744)

A huge thank-you to new contributor @lunaryorn, for contributing all of the
changes in this release!

tracing-subscriber 0.3.4

This release contains bugfixes for the fmt module, as well as documentation
improvements.

Fixed

  (#1689)
• fmt: Fixed double space before thread IDs with Pretty formatter
  (#1778)
• Several documentation improvements (#1608, #1699, #1701)

Thanks to new contributors @Swatinem and @rukai for contributing to this
release!

tracing-subscriber 0.3.3

This release fixes a pair of regressions in tracing-subscriber's fmt
module.

Fixed

• fmt: Fixed missing event fields with Compact formatter (#1755)
• fmt: Fixed PrettyFields formatter (and thus format::Pretty
  event formatter) ignoring the fmt::Layer's ANSI color code
  configuration (#1747)

tracing-subscriber 0.3.2

Fixed

• fmt: Fixed MakeWriter filtering not working with BoxMakeWriter
  (#1694)

Added

• fmt: Writer::has_ansi_escapes method to check if an output
  supports ANSI terminal formatting escape codes (#1696)
• fmt: Added additional ANSI terminal formatting to field formatters
  when supported (#1702)
• fmt: Added FmtContext::span_scope, FmtContext::event_scope,
  and FmtContext::parent_span methods for accessing the current span
  and its scope when formatting an event (#1728)
• fmt: Improved documentation on implementing event formatters (#1727)

tracing-error v0.2.0

This is a breaking change release in order to update the
tracing-subscriber dependency version to the v0.3.x release
series.

Changed

• Updated tracing-subscriber dependency to v0.3.0 (#1677)

Fixed

• Disabled default features of the tracing dependency so that
  proc-macro dependencies are not enabled (#1144)
• Documentation fixes and improvements (#635, #695)

Added

• SpanTrace: Added SpanTrace::new constructor for constructing a
  SpanTrace from a Span passed as an argument (rather than capturing
  the current span) (#1492)

Thanks to @CAD97 for contributing to this release!

tracing-subscriber v0.3.0

This is a breaking release of tracing-subscriber. The primary breaking
change in this release is the removal of the dependency on the chrono
crate, due to RUSTSEC-2020-0159. To replace chrono, support is
added for formatting timestamps using the time crate instead.

In addition, this release includes a number of other breaking API
changes, such as adding (limited) support for #![no_std] targets,
removing previously deprecated APIs, and more.

Breaking Changes

• Removed APIs deprecated in the v0.2.x release series.
• Renamed Layer::new_span to Layer::on_new_span (#1674)
• Removed Layer impl for Arc<L: Layer<S>> and Arc<dyn Layer<S> + ...>
  (#1649)
• Replaced the chrono crate with the time crate for timestamp
  formatting, to resolve RUSTSEC-2020-0159 (#1646)
• Removed json and env-filter from default features. They must now
  be enabled explicitly (#1647). This means that RUST_LOG-based filters will not
  work unless the env-filter feature is enabled.
• Changed FormatEvent::format_event and FormatFields::format_fields
  trait methods to take a Writer type, rather than a &mut dyn fmt::Write trait object (#1661)
• Changed the signature of the MakeWriter trait by adding a lifetime
  parameter (#781)

Changed

• layer: Renamed Layer::new_span to Layer::on_new_span (#1674)
• fmt: Changed FormatEvent::format_event and
  FormatFields::format_fields trait methods to take a Writer type,
  rather than a &mut dyn fmt::Write trait object (#1661)
• json, env-filter: json and env-filter feature flags are no
  longer enabled by default (#1647)

Removed

• Removed deprecated CurrentSpan type (#1320)

• registry: Removed deprecated SpanRef::parents iterator, replaced
  by SpanRef::scope in [#1431] ([#1648)])

• layer: Removed deprecated Context::scope iterator, replaced by
  Context::span_scope and Context::event_scope in #1431 and
  #1434 (#1648)

• layer: Removed Layer impl for Arc<L: Layer<S>> and Arc<dyn Layer<S> + ...>. These interfere with per-layer filtering. (#1649)

• fmt: Removed deprecated LayerBuilder type (#1673)

• fmt: Removed fmt::Layer::on_event (renamed to
  fmt::Layer::fmt_event) (#1673)

• fmt, chrono: Removed the chrono feature flag and APIs for
  using the chrono crate for timestamp formatting (#1646)

  Added

• fmt, time: LocalTime and UtcTime types for formatting
  timestamps using the time crate (#1646)

• fmt: Added a lifetime parameter to the MakeWriter trait,
  allowing it to return a borrowed writer. This enables implementations
  of MakeWriter for types such as Mutex<T: io::Write> and
  std::fs::File. (#781)

• env-filter: Documentation improvements (#1637)

• Support for some APIs on #![no_std] targets, by disabling the std
  feature flag (#1660)

Thanks to @Folyd and @nmathewson for contributing to this release!

tracing 0.1.29

This release adds support for recording Option<T> where T: Value as
typed tracing field values. It also includes significant performance
improvements for functions annotated with the #[instrument] attribute
when the generated span is disabled.

Changed

• tracing-core: updated to v0.1.21
• tracing-attributes: updated to v0.1.19

Added

• field: Value impl for Option<T> where T: Value (#1585)
• attributes: - improved performance when skipping
  #[instrument]-generated spans below the max level (#1600, #1605,
  #1614, #1616, #1617)

Fixed

• instrument: added missing Future implementation for
  WithSubscriber, making the WithDispatch extension trait actually
  useable (#1602)
• Documentation fixes and improvements (#1595, #1601, #1597)

Thanks to @BrianBurgers, @mattiast, @DCjanus, @oli-obk, and @matklad for
contributing to this release!

tracing-subscriber 0.2.25

0.2.25 (October 5, 2021)

This release fixes an issue where a Layer implementation's custom
downcast_raw implementation was lost when wrapping that layer with a
per-layer filter.

Fixed

• registry: Forward Filtered::downcast_raw to wrapped Layer
  (#1619)

Added

• Documentation improvements (#1596, #1601)

Thanks to @bryanburgers for contributing to this release!

tracing-attributes 0.1.18

0.1.18 (October 5, 2021)

Fixed

• fixed mismatched types compiler error that may occur when using
  #[instrument] on an async fn that returns an impl Trait value
  that includes a closure (#1616)
• fixed false positives for clippy::suspicious_else_formatting
  warnings due to rust-lang/rust-clippy#7760 and
  rust-lang/rust-clippy#6249 (#1617)
• fixed clippy::let_unit_value lints when using #[instrument]
  (#1614)
