Changelog

0.2.0 (2018-11-21)

• Update vendored async-profiler libraries to 1.4. From now on, clj-async-profiler ships binaries prebuilt by async-profiler maintainers themselves, no longer building them manually.
• Deprecate arities in user-facing functions that take explicit pid argument. Instead, they now retrieve :pid value from the option map. If the value is not present, use the current process as profiler target.
• Add default arity without options map for each user-facing function.
• Add profile macro which runs the profiler exactly for the duration of body.
• Make it possible to use clj-async-profiler outside of REPL environment (see clojure-goes-fast/clj-memory-meter#2 for context).
• Make the profiled event configurable through options.
• BREAKING: profile-for no longer returns a future, instead it blocks the current thread for the specified duration. You can still wrap this call in (future ...) manually if needed.

0.1.3 (2018-04-13)

• #1: Fix problems with starting the profiler with Leiningen on Linux.
• #3: Add a more informative message in case of missing agent dependencies.

0.1.2 (2018-02-09)

New options for stop and profile-for:

• :min-width - a number in pixels to limit the minimal width of a stackframe. Use this if the resulting flamegraph is too big and hangs your browser. Recommended value is from 1 to 5.
• :reverse? - if true, generate the reverse flamegraph which grows from callees up to callers.
• :icicle? - if true, invert the flamegraph upside down.

0.1.0 (2017-12-11)

The initial release of clj-async-profiler. Includes the ability to start and stop the profiler manually, profile for a period of time, and generate flamegraphs from the profiled data.
