# 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.

## 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
To generate [flamegraphs](http://samsaffron.com/archive/2013/03/19/flame-graphs-in-ruby-miniprofiler):
* 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.
