derailed_benchmarks's Issues
Error when running derailed exec perf:ram_over_time
I'm running the following command:
TEST_COUNT=50_000 derailed exec perf:ram_over_time
The name of my rails app is "job_board"
Which results in the following errors:

airbrake causing problems
Awesome project!
I'm trying to hunt down memory leaks, and I had trouble starting perf:mem_over_time until I added various Airbrake keys, but then I'm still getting an error (testing our Rails app)

The full project is https://github.com/AgileVentures/WebsiteOne/ - maybe I just turn off Airbrake - or might it be something else ...?
My rails 4.2.6 project is installing derailed_benchmarks v0.0.0 when using rake >=11
I just created a new rails 4.2.6 project. After doing setup, I added:
group :development do
gem 'stackprof'
gem 'derailed'
endAnd I tried to run it, but it fails:
/Users/MYUSER/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/bundler-1.11.2/lib/bundler/rubygems_integration.rb:355:in `block in replace_bin_path': can't find executable derailed (Gem::Exception)
from /Users/MYUSER/.rbenv/versions/2.2.3/bin/derailed:23:in `<main>'I noticed that in my Gemfile.lock says that derailed_benchmarks v0.0.0 is installed. I think that 0.0.0 is not a valid version for this gem.
To solve this, I downgraded to rake 10.5.0, and it seems to work.
I think there's some kind of issue with rake 11+
(in fact I noticed that in your gemspec the definition is: gem.add_dependency "rake", "~> 10")
Don't know how to build task 'perf:require_bench'
I did the setup however when I run:
$ rake -f perf.rake perf:require_bench
rake aborted!

or - RAILS_ENV=production bundle exec derailed exec perf:allocated_objects
I get this error and I dont know how to solve it

perf:require_bench not working as expected
I just read your great post on http://www.schneems.com/2014/11/07/i-ram-what-i-ram.html , and had to do two tweaks to get bundle exec rake -f perf.rake perf:require_bench to work as expected (using derailed_benchmarks master):
perf:require_benchloadsderailed_benchmarks/core_ext/kernel_require.rbafter the setup task is executed. This way I don't get measures for the requires that are called during bootup. My solution: Require this file inperf.rake.- With
CUT_OFF != 0, I never got any output since theTOP_REQUIREnode always has a zero cost. My workaround is to check forname != "TOP"in https://github.com/schneems/derailed_benchmarks/blob/master/lib/derailed_benchmarks/require_tree.rb#L37
I am not absolutely sure how to fix those two issues, but I at least wanted to report them as others might stumple upon similar things.
Thank you for your great work!
Task 'setup' with USE_SERVER not failing with a 302 response
I've noticed that this line seems to ignore a 302 response - is this the desired behaviour? This happens, for example, when authentication fails with a controller redirect (am learning this the hard way trying to write custom AuthHelper for my Rack app). In this case I'm assuming the generated output is from the redirect path & not the intended PATH_TO_HIT. If so this seems misleading.
Suggestion:
Curl can return response codes, so could this be used to check for a 200 response - i.e. same logic as when USE_SERVER is not set?
Consider adding option to ignore database
Thanks for this awesome gem! I used it to track down a gem that consumed a lot of memory, and submitted a pull request that eliminated the problem.
In a separate app that doesn't use a database, I just tried running derailed exec perf:mem, and it complained that it could not load database configuration. No such file - ["config/database.yml"]. Maybe I missed it, but I couldn't find a way to specify that my app doesn't use a database.
Could you include version requirements?
I could create a pull request to get this working in 1.9.3 with Rails 3.2, but in the meantime, could you provide the versions that are known to work with this gem? I really look forward to using this if I can get it running in our environment. Thanks for the work so far.

Fails with 500 error for unknown reason
I'm getting started using this gem with my Rails app. I'm trying to profile the memory usage of specific endpoints. Using the default configuration (in development mode), I get an error:
$ RAILS_ENV=development rake -f perf.rake perf:mem

Memory leak in an empty rails app?
I've got a production rails app which has been having issues as far as the server running out of memory consistently over time. I came across your gem and thought I'd try it out, and sure enough just hitting an endpoint, I consistently saw the memory output in the file being written to tmp going up and up...
However, I wanted to prove that this was in fact demonstrating the problem, so I created a new rails app (4.1.4) with ruby 2.2.5, made a single controller with an action that does:
def index
head 200
end
When I tried hitting that endpoint with bundle exec derailed exec perf:mem_over_time, the results I get are:
https://gist.github.com/patrick99e99/1fcb853bbc3fdc939053a6818462f78b
which does basically the same thing.. the number goes up and up and up.................. So......... I am a little confused? Does a brand new rails app that does nothing have a memory leak? Or am I misreading these numbers and this i actually not a problem?

Runtime Error: Bad request
I asked this question on stackoverflow and have not received an answer, so I am raising as an issue here.
I am trying to use [derailed_benchmark to track down a memory leak in a rails app.
When I run the test
USE_SERVER=puma bundle exec derailed exec perf:mem_over_time
the test runs until the memory usage starts to level off, then then the test throws an error:
RuntimeError: Bad request to "curl 'http://localhost:3000/' -s --fail 2>&1" Response:
How do I fix this?
The output is as follows:

derailed exec perf:em_over_time returns NoDatabaseError
I am trying to fix some memory leaks in my app, but when i do a derailed exec perf:mem_over_time it returns ActiveRecord::NoDatabaseError (FATAL: database "myapp_production" does not exist.
What can i do to fix it?
Support for others HTTP Method (POST, PUT, DELETE, etc...)
After reading the source code, I don't think that's it's possible to do a call with anything else than GET.
This feature could be a good idea.
What do you thing?

Any idea?
Error message is wonky when app returns non-200 status
There seems to be some weirdness going on if the app responds with a non-200 status.
- There is a bundler issue reported as an error, even though obviously derailed has already been loaded and is halfway through being used.
- The
response.bodyoutput doesn't seem to be correct.
After running bundle exec derailed exec perf:ips

Uninitialized constant User when customizing user log in
When following the instructions in the readme to supply a Devise user to authenticate I get an uninitialized constant error since the model is not loaded yet.
# broken perf.rake
require 'bundler'
Bundler.setup
require 'derailed_benchmarks'
require 'derailed_benchmarks/tasks'
DerailedBenchmarks.auth.user = User.find_by_email!("[email protected]")Monkey-patching DerailedBenchmarks::AuthHelpers::Devise using this syntax works since it defers the constant check until the app is loaded.
# working perf.rake
require 'bundler'
Bundler.setup
require 'derailed_benchmarks'
require 'derailed_benchmarks/tasks'
module DerailedBenchmarks
def auth.user
@user ||= User.find_by_email!("[email protected]")
end
endAm I missing something with the documented syntax?
If not, I can make a PR that accepts a callable for DerailedBenchmarks.auth.user.
DerailedBenchmarks.auth.user = -> { User.find_by_email!("[email protected]") }Memory allocated by gem
This is not an issue, one clarification I have been using this derailed gem to identify the memory issues and when i try this mem. Ruby 2.2.2, Rails 3.2.22
bundle exec derailed bundle:mem
TOP: 55.3398 MiB
delayed_job_active_record: 15.8789 MiB
delayed_job: 14.5352 MiB (Also required by: delayed/railtie)
delayed/yaml_ext: 10.4688 MiB
but when i try that objects
allocated memory by gem
35887974 activesupport-3.2.22
7594834 mime-types-1.25.1
7076454 newrelic_rpm-3.9.8.273
6541589 mail-2.5.4
I think there is more memory taking for this mime-types and newrelic, right? and if should i update the gem mail? i am following this link https://blog.codeship.com/debugging-a-memory-leak-on-heroku/
Subdomain support in `PATH_TO_HIT`?
Thanks for the library - I think this is the best out there for diagnosing memory issues...
Question: running against a real webserver, it looks like adding support for subdomains is possible - as we're just sub-shelling out to curl. But what about Rack::Mock? Is it possible to use subdomains in the endpoint in this case?
Thanks again!
Authentication protected app issue
I have an application where the root path is a page with omniauth-crowd authentication. Because of this, call_app fails with
Bad request: <html><body>You are being <a href="http://example.org/auth/crowd/">redirected</a>.</body></html>
Should it really consider a redirect a failure?
Detected parent died, dying
I'm trying to use this gem with puma (3.8.1) web server , but anytime I run one of the tasks, the web server dies on me with this message. I don't know what might be happening. Has anyone seen this type of error before?
Rails not being loaded in rake task?
I'm using Ruby 2.1.5+Rails 4.2.0 and derailed_benchmarks 1.0.0.
I wanted to do some tests in a Rails app that uses Devise for authenticated the User class.
I tried creating a perf.rake such as the one bellow, with and without the namespace block but I always get the error bellow. It seems that rails is not being load. Guess that I'm missing something simple..?!
Any clue?

Bundler.setup

difference between TOP vs application
hi,
running derailed in "local" production (RAILS_ENV=production bundle exec derailed exec perf:mem) gives me this :
TOP: 173.7539 MiB
application: 26.3008 MiB
while in dev I have (bundle exec derailed bundle:mem development) :
TOP: 48.4063 MiB
rails/all: 18.8047 MiB
My app do take about 180 mib on heroku. I am desperately trying to low this value. Any clue about where to look ? what does TOP mean ?
Thk U !!
Windows supported?
I have Windows 7 64bits.
When I run: "bundle exec derailed bundle:mem"
or "bundle exec derailed bundle:mem development"
I the following printed over and over again (I suspect once per gem loaded?) and that's it. This seems to indicate that ps command requested is not supported on Windows? A message in the readme would be nice if this is the case.
Usage ps [-aefl] [-u uid]
-f = show process uids, ppids
-l = show process uids, ppids, pgids, winpids
-u uid = list processes owned by uid
-a, -e = show processes of all users
-s = show process summary
-W = show windows as well as cygwin processes
PS: gem 'stackprof' doesn't even compile on Windows.

I tried this following perf.rake
class MyCustomAuth < DerailedBenchmarks::AuthHelper
def setup
# initialize code here
require 'devise'
require 'warden'
extend ::Warden::Test::Helpers
extend ::Devise::TestHelpers
Warden.test_mode!
end
def call(env)
# log something in on each request
login_as(User.last, scope: :user)
login_as(Agency.last, scope: :agency)
login_as(AdminUser.last, scope: :admin_user)
app.call(env)
end
end
DerailedBenchmarks.auth = MyCustomAuth.new
what I'm missing?

derailed bundle:mem can't load warden on MRI2.3.3?
Hiya. I'm really stumbling through this trying to get anything derailed does to work. I'm trying to debug a Sinatra application, and aside from not getting DERAILED_APP to work at all, I can't even get bundle exec derailed bundle:mem to work to benchmark gems. I have derailed in my Gemfile, and I've run bundle install but it dies immediately trying to load warden.
bundle exec derailed bundle:mem
bundler: failed to load command: derailed (/Users/shank/.rbenv/versions/2.3.3/bin/derailed)

What am I doing wrong?
How to run derailed in a Rake Task or a Test
I'm trying to test cpu/memory/gc/etc consumption in some workers that I usually run in a rake task. I created a stress test with the code to test but I would like to use derailed_benchmark to get more info.
Is there anyway to do it?
how would you go about benchmarking paths that require authentications ?
I'm trying to benchmark some pages that needs the current user to be already logged in. How would I go about this with derailed_benchmarks ?
Thanks
NoMethodError: private method `warn' called for nil:NilClass
Following the direction in the README, I installed the gem and ran "bundle exec derailed bundle:mem". I immediately get the following error:
NoMethodError: private method `warn' called for nil:NilClass
It originates on line 210 in lib/derailed_benchmarks/tasks.rb
task :ram_over_time do
Kernel.warn("The ram_over_time task is deprecated. Use mem_over_time")

Tasks: TOP => perf:require_bench => perf:setupAny suggestions on what I can do to get this to work or to disable it attempting to benchmark ActiveRecord which isn't in use in our application. Thank you for your time, I appreciate your patience.
IPS_WARMUP and IPS_TIME configuration
Hey @schneems thanks for your work on this gem!
Would you accept a PR for being able to specify the Benchmark.ips :config and :time options? As of now the perf:ips task is not useful if the endpoint you are hitting is very slow (over ~1 second) since the default :time of 5 seconds is not enough to eliminate noise. The proposed API would be
IPS_WARMUP=5 IPS_TIME=30 derailed exec perf:ips
Warning before benchmarks
This isn't a problem. Whenever I run the command derailed bundle:mem, for example, a warning is displayed:
WARN: Unresolved specs during Gem::Specification.reset:
rack (~> 1)
WARN: Clearing out unresolved specs.
Please report a bug if this causes problems.However, running the same command with bundle exec, this warning is no longer displayed. I understand what it is. If you think this relevant, we can adjust it.
Thanks, Richard.
Best!
perf:ram_over_time is stopping after couple of times
RAILS_ENV=production SKIP_FILE_WRITE=true rake -f perf.rake perf:ram_over_time TEST_COUNT=20
Doesn't matter what settings i changing it is silently stops.
Benchmarking Sinatra?
Okay, so I read #84 and the readme about how to load an arbitrary Rack app. However, I don't know much about Rack + Sinatra modular apps, or at least, enough on how to load them in derailed.
I'm trying to run bundle exec derailed exec perf:mem_over_time with the following perf.rake:
require 'derailed_benchmarks'
require 'derailed_benchmarks/tasks'
namespace :perf do
task :rack_load do
require_relative './Jump'
DERAILED_APP = Jump.run!
end
endwhere Jump is a modular Sinatra, app, e.g.,
require 'sinatra'
require 'newrelic_rpm'
require 'sinatra/partial'
require 'sinatra_more/markup_plugin'
require 'mongoid'
require 'bcrypt'
require 'raven'
require 'skylight/sinatra'
require 'redis'
require 'sidekiq'
class Jump < Sinatra::Base
# snip
endand where the config.ru is
require './Jump'
run Jump
If I start it, this happens:
$ bundle exec derailed exec perf:mem_over_time
You're not using Rails
You need to tell derailed how to boot your app
In your perf.rake add:
namespace :perf do
task :rack_load do
# DERAILED_APP = your code here
end
end
Jump development server is online.

It appears as though derailed_benchmarks (0.0.0) is being installed rather than derailed_benchmarks (1.0.0) like in other apps. When setting derailed_benchmarks explicitly to 1.0.0 in my Gemfile, I received the following:
Bundler could not find compatible versions for gem "rake":
In Gemfile:
derailed_benchmarks (~> 1.0.0) ruby depends on
rake (~> 10.4) ruby
sass-rails (~> 4.0.0) ruby depends on
railties (< 5.0, >= 4.0.0.beta) ruby depends on
rake (10.1.0)
Add "subdomain" option for mem_over_time task
I am working on diagnosing a memory leak in an app that uses a subdomain architecture. In order to use derailed's mem_over_time task, I needed to manually edit one of the files in the gem that contains a hardcoded reference to http://localhost. It would be nice if there were a SUBDOMAIN option, similar to the PATH_TO_HIT option, that allowed users to optionally supply a subdomain to hit.

there were no errors in my log, just regular hits to the server ( i set log level to debug as well ). are there any other debug flags I could set to try to figre out why its stopping early?

Allocated Memory Changes
Hello,
This code is working perfectly with our application but we are seeing some seemingly alarming results that I wanted to inquire about.
When I run:
bundle exec derailed exec perf:objects
as well as:
TEST_COUNT=10 bundle exec derailed exec perf:objects
I see our allocated memory increase by a multiple of 10. Is this normal behavior?
Here is a sample of the output I see for TEST_COUNT=1:

Defining perf:rack_load task for a non-Rails app
I am trying to use derailed_benchmarks to dynamically benchmark my Padrino app. Following the docs I have created an appropriate perf:rack_load Rake task (code below).
However, when running bundle exec derailed exec perf:mem I get the following error:
/Users/me/.rvm/gems/ruby-2.3.1/gems/derailed_benchmarks-1.3.1/lib/derailed_benchmarks/tasks.rb:72:in block (2 levels) in <top (required)>': uninitialized constant DERAILED_APP (NameError)
It appears that when this task is invoked it simply runs the code from line 46 - and not my task.
Question: Is non-Rails/Rack actually supported right now - or now do I need to fork & overwrite the rack_load task at line 46? I see using config.ru was discussed in #1 - do you need a PR to make this so?
config.ru
#!/usr/bin/env rackup
# encoding: utf-8
require File.expand_path('../config/boot.rb', __FILE__)
use Rack::Deflater
run Padrino.applicationperf.rake
require 'bundler'
Bundler.setup
require 'derailed_benchmarks'
require 'derailed_benchmarks/tasks'
namespace :perf do
desc 'loads the app for derailed_benchmarks'
task :rack_load do
require_relative '../config/boot'
DERAILED_APP = Padfoot::App
end
endGetting NoMethodError: undefined method `initialized?' error when running perf:require_bench
I'm running a Rails 3.2.19 app and when I run the perf:require_benchmarks I get the following. It works fine on a Rails 4 app though:
neel@Neels-MacBook-Pro:/railsapps/imua$ bundle exec rake -f perf.rake perf:require_bench --trace> 3.0.0) more than once.

undefined method serialize_into_session
Since I am able to move forward by using the USE_SERVER=puma option, I am trying to benchmark an endpoint that requires authentication. This is an API that uses both Devise and token based authentication. So the requests to the API typically specify an authentication token.
I tried configuring perf.rake as described in the README:
require 'bundler'
Bundler.setup
require 'derailed_benchmarks'
require 'derailed_benchmarks/tasks'
DerailedBenchmarks.auth.user = -> { User.find_by(email: "[email protected]") }
But my request:
SE_AUTH=true PATH_TO_HIT=/api/v1/myendpoint RAILS_ENV=development USE_SERVER=puma rake -f perf.rake perf:mem
...fails with the following backtrace:
Started GET "/api/v1/myendpoint" for 127.0.0.1 at 2016-01-29 13:40:19 -0800

Is `task :foo` a relic from when the project was still in development?
Noticed this task while digging through the project (really cool stuff by the way!):
Seems like it was added in your second commit, modified to remove some noise in the commit after, but then really hasn't been touched since. Also seems like it doesn't have any tests/documentation around it, and also isn't a terribly descriptive task name. 😉
Just came across it while reading through the code base and was curious if it got left in by mistake. Should be a simple exercise to remove it if that is the case, just didn't want to do it myself incase I was wrong about it's value (which happens... a lot).
