flexi_logger

Add option to bind background threads to a specific cpu core. See WriteMode::AsyncPinnedWith.

Bump minimal supported rust version to 1.83.0, due to updated dependencies.

Provide the hostname also for syslog messages of type RFC 3164 (see PR #201). Kudos goes to julienjpk-withings.

Make sure that tracing does not get confused with blanks that are normally printed into LogSpecification's Display String (issue #200), by providing a dedicated method. Kudos goes to samantehrani.

Fix issue #198. Kudos goes to hasezoey.

Add variant Cleanup::KeepForDays(usize) to have log files being deleted after a given number of days. Kudos goes to Tunglies.

Yanked.

Add syslog-call based SyslogWriter connection (kudos to AlexTMjugador).

Improve input qualification in FileSpec::try_from (fixes #194).

Add format configuration capabilities to flexi_logger::trc::setup_tracing (this is realized in a breaking change, so we do a version bump).

Add abilities

• to read the current log specification from LoggerHandle,
• to read individual module filters from the log specification

(kudos to Venus Xeon-Blonde).

Fix some clippies.

Bump minimal supported rust version to 1.82.0, due to updated dependencies.

Fix endless loop if a single log message is bigger than buffer_writer's overall limit.

Added non-default feature 'buffer_writer', which adds an in-memory log target with limited size and FIFO-logic.

Adds as additional requirement that LogWriter implementations must be 'static. Most usages don't use own LogWriter implementations, and most of those which do will not have to adapt their code. Own LogWriter implementations that really contain a non-static reference will not work anymore, but that's hard to imagine anyway. LogWriter implementations that use generics might have to adapt their requirements to the supported types (as an example, see examples/write_writer.rs).

Bump minimal supported rust version to 1.81.0.

Fix issue #185.

Fix issue #184.

Update dependencies.

Bump minimal supported rust version to 1.72.0.

Allow for custom process names when using the syslog writer (PR #182, kudos to Julien JPK).

Fix issue #181.

Increase stack sizes for flusher threads from very minimal 128 to 1024 bytes.

Add badge for OpenSSF Best Practices.

Fix issue #179 that in rotation with custom time format the custom time format was not applied properly (kudos to alboyer).

Remove the RwLock around the color palette.

Removed dependency to glob by implementing the necessary file searches explicitly, to fix issue-173.

Fix a regression (issue #178) introduced with [0.29.1].

Fix error with rotation & append & explicit directory & Naming::Timestamps.

Fix issue #176: leading underscore in log file name if only the infix is used (no basename, no start time, no discriminant).

chore: Release flexi_logger version 0.29.0

Remove unnecessary dependency to is-terminal.

Add impl From<LevelFilter> for LogSpecification.

Kudos to Oakchris1955.

Fix issue #162 (FileLogWriter does not follow its max_level), kudos to JoeWildfong.

Add special handling for empty current infix to Naming::TimestampsCustomFormat (issue #161).

Add variant Naming::TimestampsCustomFormat (issue #158), kudos to jb-alvarado.

Introduce flexi_logger::init() as super-minimal entry usage.

Update dependencies.

Detach from lazy_static, use std::sync::OnceLock instead.

Bump minimal supported rust version to 1.70.

If flexi_logger runs into issues itself, it will try to write error messages into the configured error output channel. By default, flexi_logger panics if writing to the error output channel fails. It is now possible to gracefully "swallow" the error messages and continue (see panic_if_error_channel_is_broken).

The new feature kv allows making use of the kv feature of log together with flexi_loggers format functions, and adds a dependency to log/kv_serde.

The new feature json adds a format function json_format and dependencies to serde_json, serde and serde_derive.

Add ability to omit the basename cleanly, without leading underscore (issue #153, kudos to krystejj).

Fix issue #152.

Fix wrong timestamp handling for the second rotation (second part of issue #150).

Fix issues with sub-second rotations and with cleanup when all logfiles should be compressed (issue #150).

Revise, and modify the signature of, LoggerHande::existing_log_files() (version bump).

Extend the trait LogWriter with an optional method rotate.

Extend impact of LoggerHande::trigger_rotation() to all configured writers.

Introduce new naming variants that work without _rCURRENT files: Naming::TimestampsDirect and Naming::NumbersDirect (delivers #127).

Improve documentation of filename handling.

Introduce LoggerHandle.trigger_rotation() (delivers #147).

Re-open output also for other writers (delivers #143).

Rename method to re-open output from LoggerHandle (leads to version bump).

Use dep: in Cargo.toml for references to most dependencies, in order to avoid implicit "features".

Fix #145 (minor internal optimization).

Add methods LoggerHandle::adapt_duplication_to_stderr and LoggerHandle::adapt_duplication_to_stdout (realizes issue #142).

Extend docu on providing custom format.

Use rust-script instead of cargo-script for qualification scripts.

Update dependencies.

Use display (rather than debug) formatting for thread names (kudos to mpalmer).

Add LoggerHandle::existing_log_files().

Introduce additional WriteMode variant SupportCapture.

Replace dependency atty with is-terminal, due to RUSTSEC-2021-0145.

Use chrono's support for rfc3339. Improve tests for DeferredNow.

Fix issues #132 and #133.

Update dependencies.

Bump MSRV to 1.60, because toml needs it now.

Improve documentation of feature dependencies.

Minor stuff.

Move from unmaintained ansi_term to nu-ansi-term.

Fix new clippies.

Some improvements in respect to use_utc:

• add method DeferredNow::now_utc_owned()
• documentation
• test improvement

Revert back to using chrono, since chrono is now fortunately maintained again and its timezone handling is fixed meanwhile

• this change largely reverts the changes done for [0.19.6]
• a version bump is necessary since this affects the API, e.g. in DeferredNow
• the feature use_chrono_for_offset became obsolete and is removed

On linux and Mac, improve the logic that handles the issue described again in issue-122.

Re-introduce LoggerHandle::clone().

Fix security advisory (see #117) by replacing the dependency from notify 4.0 with notify-debouncer-mini 0.2 (which depends on notify 5.0). As a side-effect, the thread flexi_logger-specfile-watcher is replaced with notify-rs debouncer loop.

Adapt and simplify the submodule trc a bit.

Fix a panic that can happen if Naming::Timestamps and FileSpec::o_suffix(None) are used and rotation happens within a second (issue-116).

Bump MSRV to 1.59 (because the time crate did this).

Switch to edition 2021, use latest patch of time version "0.3", bump minimal supported rust version to "1.57.0".

Add interconversions between log::LevelFilter and flexi_logger::Duplicate (kudos to rlee287).

Only depend on the parts of crossbeam that are used (kudos to bsilver8192).

Add support for Rfc3164 to SyslogWriter (kudos to mbodmer).

Add Clone and Copy implementations to enum Duplicate (kudos to ComplexSpaces).

Code maintenance: remove the feature "external_rotation".

Bump minimal version of time crate to "0.3.7".

Add LoggerHandle::reopen_outputfile and deprecate feature external_rotation.

Enable symlink on all unix platforms, not just linux.

Rework the optional syslog writer (kudos to ObsceneGiraffe):

• bugfix: write only full lines
• use owned buffer to avoid allocations
• encapsulate implementation details
• remove additional buffer from SyslogConnector::Tcp

Add method LoggerHandle::flw_config (kudos to Ivan Azoyan).

Reduce the used feature-list of the optional dependency chrono (to get rid of an indirect dependency to an old time version).

Add feature external_rotation.

Improve the option to use UTC for all timestamps (in filenames and log lines) (https://docs.rs/flexi_logger/latest/flexi_logger/struct.Logger.html#method.use_utc) such that the error message regarding a failed offset detection is not provoked if UTC is enforced.

The API modification done in 0.21.0 to DeferredNow is reverted.

Add option to use UTC for all timestamps (in filenames and log lines).

Add the optional feature use_chrono_for_offset as a workaround for the current behavior of time on unix.

Add an option to configure the error output channel.

Switch to time 0.3.5, and retrieve the UTC offset while flexi_logger is initialized. See also time's CHANGELOG.

Reason for the version bump:

The inner representation of DeferredNow has changed from chrono::DateTime<Local> to time::OffsetDateTime, and this is visible e.g. to implementors of format functions.
