# Heapy (Ruby Heap Dump Inspector)
[![Help Contribute to Open Source](https://www.codetriage.com/schneems/heapy/badges/users.svg)](https://www.codetriage.com/schneems/heapy) ![Supports Ruby 2.3+](https://img.shields.io/badge/ruby-2.3+-green.svg)
A CLI for analyzing Ruby Heap dumps. Thanks to [Sam Saffron](http://samsaffron.com/archive/2015/03/31/debugging-memory-leaks-in-ruby) for the idea and initial code.
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'heapy'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install heapy
## Usage
Step 1) Generate a heap dump. You could [do this manually](http://samsaffron.com/archive/2015/03/31/debugging-memory-leaks-in-ruby). Or you can use a tool like [derailed_benchmarks](https://github.com/schneems/derailed_benchmarks)
Step 2) Once you've got the heap dump, you can analyze it using this CLI:
```
$ heapy read tmp/2015-10-01T10:18:59-05:00-heap.dump
Generation: nil object count: 209191
Generation: 14 object count: 407
Generation: 15 object count: 638
Generation: 16 object count: 748
Generation: 17 object count: 1023
Generation: 18 object count: 805
# ...
```
NOTE: The reason you may be getting a "nil" generation is these objects were loaded into memory before your code began tracking the allocations. To ensure all allocations are tracked you can execute your ruby script this trick. First create a file `trace.rb` that only starts allocation tracing:
```
# trace.rb
require 'objspace'
ObjectSpace.trace_object_allocations_start
```
Now make sure this command is loaded before you run your script, you can use Ruby's `-I` to specify a load path and `-r` to specify a library to require, in this case our trace file
```
$ ruby -I ./ -r trace script_name.rb
```
If the last line of your file is invalid JSON, make sure that you are closing the file after writing the ruby heap dump to it.
## Digging into a Generation
You can drill down into a specific generation. In the previous example, the 17'th generation looks strangely large, you can drill into it:
```
$ heapy read tmp/2015-10-01T10:18:59-05:00-heap.dump 17

```
### Reviewing all generations
If you want to read all generations you can use the "all" directive
```
$ heapy read tmp/2015-10-01T10:18:59-05:00-heap.dump all
```
You can also use T-Lo's online JS based [Heap Analyzer](http://tenderlove.github.io/heap-analyzer/) for visualizations.
## Development
After checking out the repo, run `$ bundle install` to install dependencies. Then, run `rake spec` to run the tests.
To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
## Contributing
Bug reports and pull requests are welcome on GitHub at https://github.com/schneems/heapy. This project is intended to be a safe, welcoming space for collaboration, and contributors are expected to adhere to the [Contributor Covenant](contributor-covenant.org) code of conduct.
## License
The gem is available as open source under the terms of the [MIT License](http://opensource.org/licenses/MIT).

module Heapy
# This is an experimental module and likely to change. Don't use in production.
#
# Use at your own risk. APIs are not stable.
#
# == What
#
# You can use it to trace objects to see if they are still "alive" in memory.
# Unlike the heapy CLI this is meant to be used in live running code.
#
# This works by retaining an object's address in memory, then running GC
# and taking a heap dump. If the object exists in the heap dump, it is retained.
# Since we have the whole heap dump we can also do things like find what is retaining
# your object preventing it from being collected.
#
# == Use It
#
# You need to first start tracing objects:
#
# Heapy::Alive.start_object_trace!(heap_file: "./tmp/heap.json")
#
# Next in your code you want to specify the object ato trace
#
# string = "hello world"
# Heapy::Alive.trace_without_retain(string)
#
# When the code is done executing you can get a reference to all "tracer"
# objects by running:
#
# Heapy::Alive.traced_objects.each do |tracer|
# puts tracer.raw_json_hash if tracer.object_retained?
# end
#
# A few helpful methods on `tracer` objects:
#
# - `raw_json_hash` returns the hash of the object from the heap dump.
# - `object_retained?` returns truthy if the object was still present in the heap dump.
# - `address` a string of the memory address of the object you're tracing.
# - `tracked_to_s` a string that represents the object you're tracing (default
# is result of calling inspect on the method). You can pass in a custom representation
# when initializing the object. Can be useful for when `inspect` on the object you
# are tracing is too verbose.
# - `id2ref` returns the original object being traced (if it is still in memory).
# - `root?` returns false if the tracer isn't the root object.
#
# See `ObjectTracker` for more methods.
#
# If you want to see what retains an object, you can use `ObectTracker#retained_by`
# method (caution this is extremely expensive and requires re-walking the whole heap dump:
#
# Heapy::Alive.traced_objects.each do |tracer|
# if tracer.object_retained?
# puts "Traced: #{tracer.raw_json_hash}"
# tracer.retained_by.each do |retainer|
# puts " Retained by: #{retainer.raw_json_hash}"
# end
# end
# end
#
# You can iterate up the whole retained tree by using the `retained_by` method on tracers
# returned. But again it's expensive. If you have large heap dump or if you're tracing a bunch
# of objects, continuously calling `retained_by` will take lots of time. We also don't
# do any circular dependency detection so if you have two objects that depend on each other,
# you may hit an infinite loop.
#
# If you know that you'll need the retained objects of the main objects you're tracing you can
# save re-walking the heap the first N times by using the `retained_by` flag:
#
# Heapy::Alive.traced_objects(retained_by: true) do |tracer|
# # ...
# end
#
# This will pre-fetch the first level of "parents" for each object you're tracing.
#
# Did I mention this is all experimental and may change?
