+# Better Errors [![Gem Version](http://img.shields.io/gem/v/better_errors.svg)](https://rubygems.org/gems/better_errors) [![Build Status](https://travis-ci.org/charliesome/better_errors.svg)](https://travis-ci.org/charliesome/better_errors) [![Code Climate](http://img.shields.io/codeclimate/github/charliesome/better_errors.svg)](https://codeclimate.com/github/charliesome/better_errors)
+
+Better Errors replaces the standard Rails error page with a much better and more useful error page. It is also usable outside of Rails in any Rack app as Rack middleware.
+
+![image](http://i.imgur.com/6zBGAAb.png)
+
+## Features
+
+* Full stack trace
+* Source code inspection for all stack frames (with highlighting)
+* Local and instance variable inspection
+* Live REPL on every stack frame
+
+## Installation
+
+Add this to your Gemfile:
+
+```ruby
+group :development do
+  gem "better_errors"
+end
+```
+
+If you would like to use Better Errors' **advanced features** (REPL, local/instance variable inspection, pretty stack frame names), you need to add the [`binding_of_caller`](https://github.com/banister/binding_of_caller) gem by [@banisterfiend](http://twitter.com/banisterfiend) to your Gemfile:
+
+```ruby
+gem "binding_of_caller"
+```
+
+This is an optional dependency however, and Better Errors will work without it.
+
+_Note: If you discover that Better Errors isn't working - particularly after upgrading from version 0.5.0 or less - be sure to set `config.consider_all_requests_local = true` in `config/environments/development.rb`._
+
+## Security
+
+**NOTE:** It is *critical* you put better\_errors in the **development** section. **Do NOT run better_errors in production, or on Internet facing hosts.**
+
+You will notice that the only machine that gets the Better Errors page is localhost, which means you get the default error page if you are developing on a remote host (or a virtually remote host, such as a Vagrant box). Obviously, the REPL is not something you want to expose to the public, but there may also be other pieces of sensitive information available in the backtrace.
+
+To poke selective holes in this security mechanism, you can add a line like this to your startup (for example, on Rails it would be `config/environments/development.rb`)
+
+```ruby
+BetterErrors::Middleware.allow_ip! ENV['TRUSTED_IP'] if ENV['TRUSTED_IP']
+```
+
+Then run Rails like this:
+
+```shell
+TRUSTED_IP=66.68.96.220 rails s
+```
+
+Note that the `allow_ip!` is actually backed by a `Set`, so you can add more than one IP address or subnet.
+
+**Tip:** You can find your apparent IP by hitting the old error page's "Show env dump" and looking at "REMOTE_ADDR".
+
+**VirtualBox:** If you are using VirtualBox and are accessing the guest from your host's browser, you will need to use `allow_ip!` to see the error page.
+
+## Usage
+
+If you're using Rails, there's nothing else you need to do.
+
+If you're not using Rails, you need to insert `BetterErrors::Middleware` into your middleware stack, and optionally set `BetterErrors.application_root` if you'd like Better Errors to abbreviate filenames within your application.
+
+Here's an example using Sinatra:
+
+```ruby
+require "sinatra"
+require "better_errors"
+
+configure :development do
+  use BetterErrors::Middleware
+  BetterErrors.application_root = __dir__
+end
+
+get "/" do
+  raise "oops"
+end
+```
+
+### Unicorn, Puma, and other multi-worker servers
+
+Better Errors works by leaving a lot of context in server process memory. If
+you're using a web server that runs multiple "workers" it's likely that a second
+request (as happens when you click on a stack frame) will hit a different
+worker. That worker won't have the necessary context in memory, and you'll see
+a `Session Expired` message.
+
+If this is the case for you, consider turning the number of workers to one (1)
+in `development`. Another option would be to use Webrick, Mongrel, Thin,
+or another single-process server as your `rails server`, when you are trying
+to troubleshoot an issue in development.

+Middleware that displays speed badge for every html page. Designed to work both in production and in development.
+
+#### Features
+
+* database profiling. Currently supports Mysql2, Postgres, and Mongoid3 (with fallback support to ActiveRecord)
+

+
+## rack-mini-profiler needs your help
+
+We have decided to restructure our repository so there is a central UI repo and the various language implementation have their own.
+
+**WE NEED HELP.**
+
+- Setting up a build that reuses https://github.com/MiniProfiler/ui
+- Migrating the internal data structures [per the spec](https://github.com/MiniProfiler/ui)
+- Cleaning up the [horrendous class structure that is using strings as keys and crazy non-objects](https://github.com/MiniProfiler/rack-mini-profiler/blob/master/lib/mini_profiler/sql_timer_struct.rb#L36-L44)
+
+If you feel like taking on any of this start an issue and update us on your progress.
+
+## Installation
+
+Install/add to Gemfile
+
+```ruby
+gem 'rack-mini-profiler'
+```
+
+NOTE: Be sure to require rack_mini_profiler below the `pg` and `mysql` gems in your Gemfile. rack_mini_profiler will identify these gems if they are loaded to insert instrumentation. If included too early no SQL will show up.
+
+#### Rails
+
+All you have to do is include the Gem and you're good to go in development. See notes below for use in production.
+
+#### Rails and manual initialization
+
+In case you need to make sure rack_mini_profiler initialized after all other gems.
+Or you want to execute some code before rack_mini_profiler required.
+
+```ruby
+gem 'rack-mini-profiler', require: false
+```
+Note the `require: false` part - if omitted, it will cause the Railtie for the mino-profiler to
+be loaded outright, and an attempt to re-initialize it manually will raise an exception.
+
+Then put initialize code in file like `config/initializers/rack_profiler.rb`
+
+```ruby
+if Rails.env == 'development'
+  require 'rack-mini-profiler'
+
+  # initialization is skipped so trigger it
+  Rack::MiniProfilerRails.initialize!(Rails.application)
+end
+```
+
+#### Rack Builder
+
+```ruby
+require 'rack-mini-profiler'
+builder = Rack::Builder.new do
+  use Rack::MiniProfiler
+
+  map('/')    { run get }
+end
+```
+
+#### Sinatra
+
+```ruby
+require 'rack-mini-profiler'
+class MyApp < Sinatra::Base
+  use Rack::MiniProfiler
+end
+```
+
+### Flamegraphs

+* add the **flamegraph** gem to your Gemfile
+* visit a page in your app with `?pp=flamegraph`
+
+Flamegraph generation is supported in MRI 2.0 and 2.1 only.
+
+
+## Access control in production
+
+rack-mini-profiler is designed with production profiling in mind. To enable that just run `Rack::MiniProfiler.authorize_request` once you know a request is allowed to profile.
+
+```ruby
+# A hook in your ApplicationController
+def authorize
+  if current_user.is_admin?
+    Rack::MiniProfiler.authorize_request
+  end
+end
+```
+
+## Configuration
+
+Various aspects of rack-mini-profiler's behavior can be configured when your app boots.
+For example in a Rails app, this should be done in an initializer:
+**config/initializers/mini_profiler.rb**
+
+### Storage
+
+rack-mini-profiler stores its results so they can be shared later and aren't lost at the end of the request.
+
+There are 4 storage options: `MemoryStore`, `RedisStore`, `MemcacheStore`, and `FileStore`.
+
+`FileStore` is the default in Rails environments and will write files to `tmp/miniprofiler/*`.  `MemoryStore` is the default otherwise.
+
+```ruby
+# set MemoryStore
+Rack::MiniProfiler.config.storage = Rack::MiniProfiler::MemoryStore
+
+# set RedisStore
+if Rails.env.production?
+  uri = URI.parse(ENV["REDIS_SERVER_URL"])
+  Rack::MiniProfiler.config.storage_options = { :host => uri.host, :port => uri.port, :password => uri.password }
+  Rack::MiniProfiler.config.storage = Rack::MiniProfiler::RedisStore
+end
+```
+
+MemoryStore stores results in a processes heap - something that does not work well in a multi process environment.
+FileStore stores results in the file system - something that may not work well in a multi machine environment.
+RedisStore/MemcacheStore work in multi process and multi machine environments (RedisStore only saves results for up to 24 hours so it won't continue to fill up Redis).
+
+Additionally you may implement an AbstractStore for your own provider.
+
+### User result segregation
+
+MiniProfiler will attempt to keep all user results isolated, out-of-the-box the user provider uses the ip address:
+
+```ruby
+Rack::MiniProfiler.config.user_provider = Proc.new{|env| Rack::Request.new(env).ip}
+```
+
+You can override (something that is very important in a multi-machine production setup):
+
+```ruby
+Rack::MiniProfiler.config.user_provider = Proc.new{ |env| CurrentUser.get(env) }
+```
+
+The string this function returns should be unique for each user on the system (for anonymous you may need to fall back to ip address)
+
+### Configuration Options
+
+You can set configuration options using the configuration accessor on `Rack::MiniProfiler`.
+For example:
+
+```ruby
+Rack::MiniProfiler.config.position = 'right'
+Rack::MiniProfiler.config.start_hidden = true
+```
+The available configuration options are:
+
+* pre_authorize_cb - A lambda callback you can set to determine whether or not mini_profiler should be visible on a given request. Default in a Rails environment is only on in development mode. If in a Rack app, the default is always on.
+* position - Can either be 'right' or 'left'. Default is 'left'.
+* skip_schema_queries - Whether or not you want to log the queries about the schema of your tables. Default is 'false', 'true' in rails development.
+* auto_inject (default true) - when false the miniprofiler script is not injected in the page
+* backtrace_filter - a regex you can use to filter out unwanted lines from the backtraces
+* toggle_shortcut (default Alt+P) - a jquery.hotkeys.js-style keyboard shortcut, used to toggle the mini_profiler's visibility. See http://code.google.com/p/js-hotkeys/ for more info.
+* start_hidden (default false) - Whether or not you want the mini_profiler to be visible when loading a page
+* backtrace_threshold_ms (default zero) - Minimum SQL query elapsed time before a backtrace is recorded. Backtrace recording can take a couple of milliseconds on rubies earlier than 2.0, impacting performance for very small queries.
+* flamegraph_sample_rate (default 0.5ms) - How often fast_stack should get stack trace info to generate flamegraphs
+
+### Custom middleware ordering (required if using `Rack::Deflate` with Rails)
+
+If you are using `Rack::Deflate` with rails and rack-mini-profiler in its default configuration,
+`Rack::MiniProfiler` will be injected (as always) at position 0 in the middleware stack. This
+will result in it attempting to inject html into the already-compressed response body. To fix this,
+the middleware ordering must be overriden.
+
+To do this, first add `, require: false` to the gemfile entry for rack-mini-profiler.
+This will prevent the railtie from running. Then, customize the initialization
+in the initializer like so:
+
+```ruby
+require 'rack-mini-profiler'
+
+Rack::MiniProfilerRails.initialize!(Rails.application)
+
+Rails.application.middleware.delete(Rack::MiniProfiler)
+Rails.application.middleware.insert_after(Rack::Deflater, Rack::MiniProfiler)
+```
+
+Deleting the middleware and then reinserting it is a bit inelegant, but
+a sufficient and costless solution. It is possible that rack-mini-profiler might
+support this scenario more directly if it is found that
+there is significant need for this confriguration or that
+the above recipe causes problems.
+
+
+## Special query strings
+
+If you include the query string `pp=help` at the end of your request you will see the various options available. You can use these options to extend or contract the amount of diagnostics rack-mini-profiler gathers.
+
+
+## Rails 2.X support
+
+To get MiniProfiler working with Rails 2.3.X you need to do the initialization manually as well as monkey patch away an incompatibility between activesupport and json_pure.
+
+Add the following code to your environment.rb (or just in a specific environment such as development.rb) for initialization and configuration of MiniProfiler.
+
+```ruby
+# configure and initialize MiniProfiler
+require 'rack-mini-profiler'
+c = ::Rack::MiniProfiler.config
+c.pre_authorize_cb = lambda { |env|
+  Rails.env.development? || Rails.env.production?
+}
+tmp = Rails.root.to_s + "/tmp/miniprofiler"
+FileUtils.mkdir_p(tmp) unless File.exists?(tmp)
+c.storage_options = {:path => tmp}
+c.storage = ::Rack::MiniProfiler::FileStore
+config.middleware.use(::Rack::MiniProfiler)
+::Rack::MiniProfiler.profile_method(ActionController::Base, :process) {|action| "Executing action: #{action}"}
+::Rack::MiniProfiler.profile_method(ActionView::Template, :render) {|x,y| "Rendering: #{path_without_format_and_extension}"}
+
+# monkey patch away an activesupport and json_pure incompatability
+# http://pivotallabs.com/users/alex/blog/articles/1332-monkey-patch-of-the-day-activesupport-vs-json-pure-vs-ruby-1-8
+if JSON.const_defined?(:Pure)
+  class JSON::Pure::Generator::State
+    include ActiveSupport::CoreExtensions::Hash::Except
+  end
+end
+```
+
+## Running the Specs
+
+```
+$ rake build
+$ rake spec
+```
+
+Additionally you can also run `autotest` if you like.
