Releases

v1.5.1

  • Improve performance of object table.

v1.5.0

  • Add Capture#each_object for getting all retained objects.
  • Add retained_addresses: option to Sampler#analyze to capture addresses.
  • Add Sampler#analyze(retained_minimum: 100) - if the retained_size is less than this, the analyse won't proceed.
  • Remove Memory::Profiler::Graph - it's too slow for practical use.
  • Add Memory::Profiler.address_of(object) to get the memory address of an object.

v1.4.0

  • Implement Cooper-Harvey-Kennedy algorithm for finding root objects in memory leaks.
  • Rework capture to track objects by object_id exclusively.

v1.3.0

  • Breaking: Renamed Capture#count_for to Capture#retained_count_of for better clarity and consistency.
  • Breaking: Changed CallTree#top_paths(limit) to CallTree#top_paths(limit:) - now uses keyword argument.
  • Breaking: Changed CallTree#hotspots(limit) to CallTree#hotspots(limit:) - now uses keyword argument.
  • Simplified Sampler#analyze return structure to {allocations: {...}, call_tree: {...}} format.
  • Added Allocations#as_json and Allocations#to_json methods for JSON serialization.
  • Added CallTree#as_json and CallTree#to_json methods for JSON serialization with configurable options.
  • Memory::Profiler::Allocations.new can now be instantiated directly (primarily for testing).
  • Sampler#statistics is now a deprecated alias for Sampler#analyze.
  • Breaking: Removed Sampler#all_statistics method.

v1.2.0

  • Enable custom depth: and filter: options to Sampler#track.
  • Change default filter to no-op.
  • Add option to run GC with custom options before each sample to reduce noise.
  • Always report sampler statistics after each sample.

v1.1.15

  • Ignore freeobj for classes that are not being tracked.

v1.1.14

  • Ignore freeobj events for objects with anonymous classes that are not tracked (and thus become T_NONE).

v1.1.13

  • Fix sampler loop interval handling.
  • Log capture statistics from sampler run loop.

v1.1.12

  • Use rb_obj_id for tracking object states to avoid compaction issues.

v1.1.11

  • Double buffer shared events queues to fix queue corruption.

v1.1.10

  • Added Capture#new_count - returns total number of allocations tracked across all classes.
  • Added Capture#free_count - returns total number of objects freed across all classes.
  • Added Capture#retained_count - returns retained object count (new_count - free_count).
  • Critical: Fixed GC crash during compaction caused by missing write barriers in event queue.
  • Fixed allocation/deallocation counts being inaccurate when objects are allocated during callbacks or freed after compaction.
  • Capture#clear now raises RuntimeError if called while capture is running. Call stop() before clear().

v1.1.9

  • More write barriers...

v1.1.8

  • Use single global queue for event handling to avoid incorrect ordering.

v1.1.7

  • Expose Capture#statistics for debugging internal memory tracking state.

v1.1.6

  • Write barriers all the things.
  • Better state handling and object increment/decrement counting.
  • Better call tree handling - including support for prune!.

v1.1.5

  • Use queue for newobj too to avoid invoking user code during object allocation.

v1.1.2

  • Fix handling of GC compaction (I hope).

v0.1.0

  • Initial implementation.
