6.2.2 (2023-07-18)

📦 Available on Clojars

Identical to 6.2.1, but synchronizes Encore dependency with my recent library releases (Timbre, Tufte, Sente, Carmine, etc.) to prevent confusion caused by dependency conflicts.

This is a safe update for users of 6.2.1.

Migration checklist

• Removed vars: timbre/config, timbre/level-atom, default-fmt-output-fn
• The fn signature for set-config! has changed: [ks val] -> [config]
• Middleware now apply left->right, not right->left
• Renamed a default appender: :standard-out -> :println
• Renamed config opts: :timestamp-pattern, :timestamp-locale -> :timestamp-opts {:pattern _ :locale _ :timezone _}
• Renamed config opts: :whitelist -> :ns-whitelist, :blacklist -> :ns-blacklist
• Appender :rate-limit format has changed: [ncalls ms] -> [[ncalls ms] <...>]
• Renamed appender args: :ns->:?ns-str, :file->:?file, :line->:?line
• Appender args now wrapped with delays: :throwable->:?err_, :message->:msg_, :timestamp->:timestamp_, :hostname->:hostname_, :args->:vargs_
• Appender args removed: :output, :ap-config
• Appender args added: :output-fn (fn [data]) -> string
• stacktrace util fn signature changed: [throwable & [sep fonts] -> [err & [opts]]
• All bundled 3rd-party appenders have moved to a new 3rd-party ns.
• Bundled 3rd-party appender constructor signatures may have changed, please double check.

Apologies for the hassle in migrating. The changes made here all bring serious benefits (performance, simplicity, future extensibility, cross-platform support) and I'm confident that v4's the last time I'll need to touch the core design. Future work will be focused on polish, stability, and better+more bundled appenders.

v3.0.0 / 2014 Jan 30

Major update, non-breaking though users with custom appenders are encouraged to view the Changes section below. This version polishes up the codebase and general design. Tightened up a few aspects of how appenders and appender middleware work. Added a serializing Carmine appender (I use something similar in prod most of the time). Also finally added facilities for ad hoc (non-atom) logging configuration.

Overall quite happy with the state of Timbre as of this release. No major anticipated improvements/changes from here (modulo bugs).

New

• Android appender, courtesy of AdamClements.
• Rolling appender, courtesy of megayu.
• Powerful, high-performance Carmine (Redis) appender: query-able, rotating serialized log entries by log level. See README or appender's docstring for details. (Recommended!)
• Appender rate limits now specified in a more flexible format: [ncalls window-msecs], e.g. [1 2000] for 1 write / 2000 msecs.
• Appender rate limits now also apply (at 1/4 ncalls) to any particular logging arguments in the same time window. This helps prevent a particular logging call from flooding the limiter and preventing other calls from getting through.
• sometimes macro that executes body with given probability. Useful for sampled logging (e.g. email a report for 0.01% of user logins in production).
• log and logf macros now take an optional logging config map as their first argument: (log :info "hello") => use @timbre/config, (log <config> :info "hello") => use <config>.
• Appenders can now specify an optional :fmt-output-opts that'll get passed to fmt-output-fn for any special formatting requirements they may have (e.g. the Postal email appender provides an arg to suppress ANSI colors in stacktrace output).

Changes

• EXPERIMENTAL: stacktraces now formatted with io.aviso/pretty rather than clj-stacktrace. Feedback on this (esp. coloring) welcome!
• DEPRECATED: red, green, blue -> use color-str instead.
• DEPRECATED: config prefix-fn has been replaced by the more flexible fmt-output-fn. Change is backwards compatible.
• REMOVED: Per-appender :prefix option dropped - was unnecessary. If an appender wants custom output formatting, it can do so w/o using an in-config formatter.
• Update refer-timbre (add profiling, logf variations, etc.).
• DEPRECATED: atom logging level is now located in level-atom rather than config. Old in-config levels will be respected (i.e. change is backwards compatible).
• DEPRECATED: appender rate limits are now specified as :rate-limit [ncalls window-msecs] rather than :limit-per-msecs ncalls. Change is backwards compatible.
• Built-in appenders have been simplified using the new default-output appender arg.
• Postal appender now generates a more useful subject in most cases.

Fixes

• #38 Broken namespace filter (mlb-).
• Messages are now generated after middleware has been applied, allowing better filtering performance and more intuitive behaviour (e.g. changes to args in middleware will now automatically percolate to message content).
• (logf <level> "hello %s") was throwing due to lack of formatting args.

v2.6.3 → v2.7.1

• Core: getHostName no longer runs on the main thread for better Android compatibility (AdamClements).
• Profiling: added defnp macro.
• Profiling: fix compile-time name creation: now runtime (aperiodic).
• Appenders: added rotating file appender (mopemope).

v2.5.0 → v2.6.3

• Perf: add support for a compile-time logging level environment variable (TIMBRE_LOG_LEVEL). See timbre/compile-time-level docstring for details.
• Fix: use-timbre, str-println bugs.
• Fix: Null Pointer Exception in clj-stacktrace (bitemyapp).

v2.4.1 → v2.5.0

• Added :file and :line appender args.
• Fixed make-timestamp-fn thread safety.

v2.3.4 → v2.4.1

• Added refer-timbre for conveniently requireing standard timbre vars.
• Postal appender now uses throwable as subject when no other args given.
• log-errors, log-and-rethrow-errors now catch Throwable instead of Exception.

v2.2.0 → v2.3.4

• Added with-log-level for thread-local logging levels: (with-level :trace (trace "This will log!")). Esp. useful for developing & unit tests, etc.

v2.1.2 → v2.2.0

• Add socket, MongoDB appenders (thanks to emlyn).

v2.0.0 → v2.1.2

• Added appenders: socket, IRC, MongoDB (CongoMongo). See README for details.
• Add ex-data output to stacktrace fn.
• Fixed a number of small bugs (mostly regressions from 1.x).

v1.6.0 → v2.0.0

• Refactor for integration with tools.logging.

• BREAKING: Drop Clojure 1.3 support.

• DEPRECATED: :max-messages-per-msecs appender arg -> :limit-per-msecs.

• BREAKING: :more appender arg has been dropped. :message arg is now a string of all arguments as joined by logp/logf. Appenders that need unjoined logging arguments (i.e. raw arguments as given to logp/logf) should use the new :log-args vector.

• BREAKING: Stacktraces are no longer automatically generated at the log-macro level. Stacktraces are now left as an appender implementation detail. A :throwable appender argument has been added along with a stacktrace fn.
