# 0.1.35 (June 8, 2022)
|
|
|
|
This release reduces the overhead of callsite registration by using new
|
|
`tracing-core` APIs.
|
|
|
|
### Added
|
|
|
|
- Use `DefaultCallsite` to reduce callsite registration overhead ([#2083])
|
|
|
|
### Changed
|
|
|
|
- `tracing-core`: updated to [0.1.27][core-0.1.27]
|
|
|
|
[core-0.1.27]: https://github.com/tokio-rs/tracing/releases/tag/tracing-core-0.1.27

|
# 0.1.34 (April 14, 2022)
|
|
|
|
This release includes bug fixes for the "log" support feature and for the use of
|
|
both scoped and global default dispatchers in the same program.
|
|
|
|
### Fixed
|
|
|
|
- Failure to use the global default dispatcher when a thread sets a local
|
|
default dispatcher before the global default is set ([#2065])
|
|
- **log**: Compilation errors due to `async` block/fn futures becoming `!Send`
|
|
when the "log" feature flag is enabled ([#2073])
|
|
- Broken links in documentation ([#2068])
|
|
|
|

# 0.1.33 (April 9, 2022)
|
|
|
|
This release adds new `span_enabled!` and `event_enabled!` variants of the
|
|
`enabled!` macro, for testing whether a subscriber would specifically enable a
|
|
span or an event.
|
|
|
|
### Added
|
|
|
|
- `span_enabled!` and `event_enabled!` macros ([#1900])
|
|
- Several documentation improvements ([#2010], [#2012])
|
|
|
|
### Fixed
|
|
|
|
- Compilation warning when compiling for <=32-bit targets (including `wasm32`)
|
|
([#2060])
|
|
|
|

# 0.1.32 (March 8th, 2022)
|
|
|
|
This release reduces the overhead of creating and dropping disabled
|
|
spans significantly, which should improve performance when no `tracing`
|
|
subscriber is in use or when spans are disabled by a filter.
|
|
|
|
### Fixed
|
|
|
|
- **attributes**: Compilation failure with `--minimal-versions` due to a
|
|
too-permissive `syn` dependency ([#1960])
|
|
|
|
### Changed
|
|
|
|
- Reduced `Drop` overhead for disabled spans ([#1974])
|
|
- `tracing-attributes`: updated to [0.1.20][attributes-0.1.20]

# 0.1.31 (February 17th, 2022)
|
|
|
|
This release increases the minimum supported Rust version (MSRV) to 1.49.0. In
|
|
addition, it fixes some relatively rare macro bugs.
|
|
|
|
### Added
|
|
|
|
- Added `tracing-forest` to the list of related crates ([#1935])
|
|
|
|
### Changed
|
|
|
|
- Updated minimum supported Rust version (MSRV) to 1.49.0 ([#1913])
|
|
|
|
### Fixed
|
|
|
|
- Fixed the `warn!` macro incorrectly generating an event with the `TRACE` level
|
|
([#1930])
|
|
- Fixed macro hygiene issues when used in a crate that defines its own `concat!`
|
|
macro, for real this time ([#1918])
|
|
|
|

# 0.1.30 (February 3rd, 2022)
|
|
|
|
This release adds *experimental* support for recording structured field
|
|
values using the [`valuable`] crate. See [this blog post][post] for
|
|
details on `valuable`.
|
|
|
|
Note that `valuable` support currently requires `--cfg tracing_unstable`. See
|
|
the documentation for details.
|
|
|
|
This release also adds a new `enabled!` macro for testing if a span or event
|
|
would be enabled.
|
|
|
|
### Added
|
|
|
|
- **field**: Experimental support for recording field values using the
|
|
[`valuable`] crate ([#1608], [#1888], [#1887])
|
|
- `enabled!` macro for testing if a span or event is enabled ([#1882])
|
|
|
|
### Changed
|
|
|
|
- `tracing-core`: updated to [0.1.22][core-0.1.22]
|
|
- `tracing-attributes`: updated to [0.1.19][attributes-0.1.19]
|
|
|
|
### Fixed
|
|
|
|
- **log**: Fixed "use of moved value" compiler error when the "log" feature is
|
|
enabled ([#1823])
|
|
- Fixed macro hygiene issues when used in a crate that defines its own `concat!`
|
|
macro ([#1842])
|
|
- A very large number of documentation fixes and improvements.
|
|
|
|

# 0.1.29 (October 5th, 2021)
|
|
|
|
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 v0.1.18
|
|
|
|
### 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])
|
|
|
|

# 0.1.28 (September 17th, 2021)
|
|
|
|
This release fixes an issue where the RustDoc documentation was rendered
|
|
incorrectly. It doesn't include any actual code changes, and is very boring and
|
|
can be ignored.
|
|
|
|
### Fixed
|
|
|
|
- **docs**: Incorrect documentation rendering due to unclosed `<div>` tag
|
|
([#1572])
|
|
|
|
[#1572]: https://github.com/tokio-rs/tracing/pull/1572
|
|
|
|
# 0.1.27 (September 13, 2021)
|
|
|
|
This release adds a new [`Span::or_current`] method to aid in efficiently
|
|
propagating span contexts to spawned threads or tasks. Additionally, it updates
|
|
the [`tracing-core`] version to [0.1.20] and the [`tracing-attributes`] version to
|
|
[0.1.16], ensuring that a number of new features in those crates are present.
|
|
|
|
### Fixed
|
|
|
|
- **instrument**: Added missing `WithSubscriber` implementations for futures and
|
|
other types ([#1424])
|
|
|
|
### Added
|
|
|
|
- `Span::or_current` method, to help with efficient span context propagation
|
|
([#1538])
|
|
- **attributes**: add `skip_all` option to `#[instrument]` ([#1548])
|
|
- **attributes**: record primitive types as primitive values rather than as
|
|
`fmt::Debug` ([#1378])
|
|
- **core**: `NoSubscriber`, a no-op `Subscriber` implementation
|
|
([#1549])
|
|
- **core**: Added `Visit::record_f64` and support for recording floating-point
|
|
values ([#1507], [#1522])
|
|
- A large number of documentation improvements and fixes ([#1369], [#1398],
|
|
[#1435], [#1442], [#1524], [#1556])
|
|

# 0.1.26 (April 30, 2021)
|
|
|
|
### Fixed
|
|
|
|
- **attributes**: Compatibility between `#[instrument]` and `async-trait`
|
|
v0.1.43 and newer ([#1228])
|
|
- Several documentation fixes ([#1305], [#1344])
|
|
### Added
|
|
|
|
- `Subscriber` impl for `Box<dyn Subscriber + Send + Sync + 'static>` ([#1358])
|
|
- `Subscriber` impl for `Arc<dyn Subscriber + Send + Sync + 'static>` ([#1374])
|
|
- Symmetric `From` impls for existing `Into` impls on `span::Current`, `Span`,
|
|
and `Option<Id>` ([#1335], [#1338])
|
|
- `From<EnteredSpan>` implementation for `Option<Id>`, allowing `EnteredSpan` to
|
|
be used in a `span!` macro's `parent:` field ([#1325])
|
|
- `Attributes::fields` accessor that returns the set of fields defined on a
|
|
span's `Attributes` ([#1331])
|
|
|

|
|
|
|
### Added
|

|
|
`#[instrument]` with `async-trait` ([#977])
|
|
- **attributes** Removed unused `syn` features ([#928])
|
|
- **log**: Fixed an issue where the `tracing` macros would generate code for
|
|
events whose levels are disabled statically by the `log` crate's

`static_max_level_XXX` features ([#1175])
|
|
- Fixed deprecations and clippy lints ([#1195])

|
|
|
|
### Fixed
|
|
|
|
- Incorrect inlining of `Span::new`, `Span::new_root`, and `Span::new_child_of`,
|
|
which could result in `dispatcher::get_default` being inlined at the callsite
|
|
([#994])
|
|
- Regression where using a struct field as a span or event field when other
|
|
fields on that struct are borrowed mutably would fail to compile ([#987])
|
|
|
|
### Changed
|
|
|
|
- Updated `tracing-core` to 0.1.17 ([#992])
|
|
|
|

|
|
|
|

|
|
|
- Fixed a bug where `LevelFilter::OFF` (and thus also the `static_max_level_off`
|
|
feature flag) would enable *all* traces, rather than *none* (#853)
|
|
- **log**: Fixed `tracing` macros and `Span`s not checking `log::max_level`
|
|
before emitting `log` records (#870)
|
|
|
|
### Changed
|
|
|
|
- **macros**: Macros now check the global max level (`LevelFilter::current`)
|
|
before the per-callsite cache when determining if a span or event is enabled.
|
|
This significantly improves performance in some use cases (#853)
|
|
- **macros**: Simplified the code generated by macro expansion significantly,
|
|
which may improve compile times and/or `rustc` optimizatation of surrounding
|
|
code (#869, #869)
|
|
- **macros**: Macros now check the static max level before checking any runtime
|
|
filtering, improving performance when a span or event is disabled by a
|
|
`static_max_level_XXX` feature flag (#868)
|
|
- `LevelFilter` is now a re-export of the `tracing_core::LevelFilter` type, it
|
|
can now be used interchangably with the versions in `tracing-core` and
|
|
`tracing-subscriber` (#853)
|
|
- Significant performance improvements when comparing `LevelFilter`s and
|
|
`Level`s (#853)
|
|
- Updated the minimum `tracing-core` dependency to 0.1.12 (#853)
|
|
|
|
### Added
|
|
|
|
- **macros**: Quoted string literals may now be used as field names, to allow
|
|
fields whose names are not valid Rust identifiers (#790)
|
|
- **docs**: Several documentation improvements (#850, #857, #841)
|
|
- `LevelFilter::current()` function, which returns the highest level that any
|
|
subscriber will enable (#853)
|
|
- `Subscriber::max_level_hint` optional trait method, for setting the value
|
|
returned by `LevelFilter::current()` (#853)
|
|

# 0.1.17 (July 22, 2020)
|
|
|
|
### Changed
|
|
|
|
- **log**: Moved verbose span enter/exit log records to "tracing::span::active"
|
|
target, allowing them to be filtered separately (#833)
|
|
- **log**: All span lifecycle log records without fields now have the `Trace`
|
|
log filter, to guard against `log` users enabling them by default with blanket
|
|
level filtering (#833)
|
|
|
|
### Fixed
|
|
|
|
- **log**/**macros**: Fixed missing implicit imports of the
|
|
`tracing::field::debug` and `tracing::field::display` functions inside the
|
|
macros when the "log" feature is enabled (#835)
|
|
|
|
# 0.1.16 (July 8, 2020)
|
|
|
|
### Added
|
|
|
|

|
|
- **attributes**: `#[instrument]` now emits a compiler warning when ignoring unrecognized
|
|
input (#672, #786)
|
|
- Improved documentation on using `tracing` in async code (#769)
|
|
|
|
### Changed
|
|
|
|
- Updated `tracing-core` dependency to 0.1.11
|
|
|
|
### Fixed
|
|
|
|
- **macros**: Excessive monomorphization in macros, which could lead to
|
|
longer compilation times (#787)
|
|
- **log**: Compiler warnings in macros when `log` or `log-always` features
|
|
are enabled (#753)
|
|
- Compiler error when `tracing-core/std` feature is enabled but `tracing/std` is
|
|
not (#760)
|
|
|
|

|
|

|
|
[`async-trait`] trait implementations (#711)

|
an event if an instrumented function returns `Err` (#637)
|

|
|
`subscriber::set_default` (#685)
|
|
