This +means that events emitted by the `Future`'s `Drop` implementation will now be +recorded within its `Span`. It also adds `#[inline]` hints to methods called in +the `event!` macro's expansion, for an improvement in both binary size and +performance. + +Additionally, this release updates the `tracing-attributes` dependency to +[v0.1.24][attrs-0.1.24], which updates the [`syn`] dependency to v2.x.x. +`tracing-attributes` v0.1.24 also includes improvements to the `#[instrument]` +macro; see [the `tracing-attributes` 0.1.24 release notes][attrs-0.1.24] for +details. + +### Added + +- `Instrumented` futures will now enter the attached `Span` in their `Drop` + implementation, allowing events emitted when dropping the future to occur + within the span ([#2562]) +- `#[inline]` attributes for methods called by the `event!` macros, making + generated code smaller ([#2555]) +- **attributes**: `level` argument to `#[instrument(err)]` and + `#[instrument(ret)]` to override the level of + the generated return value event ([#2335]) +- **attributes**: Improved compiler error message when `#[instrument]` is added to a `const fn` + ([#2418]) + +### Changed + +- `tracing-attributes`: updated to [0.1.24][attrs-0.1.24] +- Removed unneeded `cfg-if` dependency ([#2553]) +- **attributes**: Updated [`syn`] dependency to 2.0 ([#2516]) + +### Fixed + +- **attributes**: Fix `clippy::unreachable` warnings in `#[instrument]`-generated code ([#2356]) +- **attributes**: Removed unused "visit" feature flag from `syn` dependency ([#2530]) + +### Documented + +- **attributes**: Documented default level for `#[instrument(err)]` ([#2433]) +- **attributes**: Improved documentation for levels in `#[instrument]` ([#2350]) + +Thanks to @nitnelave, @jsgf, @Abhicodes-crypto, @LukeMathWalker, @andrewpollack, +@quad, @klensy, @davidpdrsn, @dbidwell94, @ldm0, @NobodyXu, @ilsv, and @daxpedda +for contributing to this release! + +[`syn`]: https://crates.io/crates/syn +[attrs-0.1.24]: + https://github.com/tokio-rs/tracing/releases/tag/tracing-attributes-0.1.24 +[#2565]: https://github.com/tokio-rs/tracing/pull/2565 +[#2555]: https://github.com/tokio-rs/tracing/pull/2555 +[#2553]: https://github.com/tokio-rs/tracing/pull/2553 +[#2335]: https://github.com/tokio-rs/tracing/pull/2335 +[#2418]: https://github.com/tokio-rs/tracing/pull/2418 +[#2516]: https://github.com/tokio-rs/tracing/pull/2516 +[#2356]: https://github.com/tokio-rs/tracing/pull/2356 +[#2530]: https://github.com/tokio-rs/tracing/pull/2530 +[#2433]: https://github.com/tokio-rs/tracing/pull/2433 +[#2350]: https://github.com/tokio-rs/tracing/pull/2350 + # 0.1.37 (October 6, 2022) This release of `tracing` incorporates changes from `tracing-core` diff --git a/tracing/Cargo.toml b/tracing/Cargo.toml index 234c4ce0d5..cfa60ac7c8 100644 --- a/tracing/Cargo.toml +++ b/tracing/Cargo.toml @@ -8,7 +8,7 @@ name = "tracing" # - README.md # - Update CHANGELOG.md. # - Create "v0.1.x" git tag -version = "0.1.37" +version = "0.1.38" authors = ["Eliza Weisman ", "Tokio Contributors "] license = "MIT" readme = "README.md" @@ -30,7 +30,7 @@ rust-version = "1.56.0" [dependencies] tracing-core = { path = "../tracing-core", version = "0.1.30", default-features = false } log = { version = "0.4.17", optional = true } -tracing-attributes = { path = "../tracing-attributes", version = "0.1.23", optional = true } +tracing-attributes = { path = "../tracing-attributes", version = "0.1.24", optional = true } pin-project-lite = "0.2.9" [dev-dependencies] diff --git a/tracing/README.md b/tracing/README.md index 1de6560a66..443e51458d 100644 --- a/tracing/README.md +++ b/tracing/README.md @@ -98,7 +98,7 @@ fn main() { ```toml [dependencies] tracing = "0.1" -tracing-subscriber = "0.2.0" +tracing-subscriber = "0.3.0" ``` This subscriber will be used as the default in all threads for the remainder of the duration @@ -250,7 +250,7 @@ my_future is as long as the future's.
