When working on my app locally using thin and ssl (thin start --ssl), I randomly get this error message every 5/10 requests.
PG::ConnectionBad: PQconsumeInput() SSL error: internal error
Usually I relaunch the query and it goes well, but it is a pain to having to refresh and being constantly interupted by this not understandable bug.
Here is the full stacktrace:
PG::ConnectionBad: PQconsumeInput() SSL error: internal error
: SELECT "users".* FROM "users" WHERE "users"."id" = 1 LIMIT 1
Completed 500 Internal Server Error in 3.6ms
ActiveRecord::StatementInvalid - PG::ConnectionBad: PQconsumeInput() SSL error: internal error

I found this issue but it still remains unsolved.
Any clue on what I should do?
Thanks god it doesn't happen in production, not even in staging, only locally.
I'm using:
thin --version
thin 1.6.2 codename Doc Brown
rails --version
Rails 3.2.18
ruby --version
ruby 1.9.3p545 (2014-02-24 revision 45159) [x86_64-linux]
psql --version
psql (PostgreSQL) 9.1.13
Thanks in advance
I've been having the same problem for a few weeks now, today out of a hunch I added a pool: 1 in to the relevant section of my config/database.yml and now the error seems to have gone away.
Basically were are asking rails to not do connection pooling I in this case.
development:
adapter: postgresql
host: ec2-54-83-14-68.compute-1.amazonaws.com
username: rxeabczdnbhabc
password: hiddenZFYd1Mv-abEE9jhidden
database: d93f8pheuqtni3
pool: 1

I occasionally get MySQL server has gone away on my Rails 3.2.13/Ruby 1.9.3 app, hosted on a Google Compute Engine instance, connecting to a Cloud SQL D1 (512 MB) instance. The traffic is very low. The problem goes away when the site is reloaded, but it's too late since an HTTP 500 is already produced.
Any suggestions on what to tune? Does the MySQL server disconnect due to low traffic?

The observed behavior, most likely, is a result of the billing plan configured for the instance. If 'per use' billing plan is used; the instance will spin up when accessed and will continue to be up 15 min after the last access.
For more details take a look at "Pricing and Billing" section here.
Another consideration is that Google Compute Engine kills times out idle connections. This issue and the workaround are described in the old Cloud SQL Google Group:
https://groups.google.com/forum/#!msg/google-cloud-sql-discuss/cLLxUxiS5ck/c5dsYCvZhDEJ

I'm following through Railscast #235 "Devise + OmniAuth Revised" and have run into a NoMethodError for Username whenever I try to authenticate using Twitter. I'm running Rails 3.2.
Specifically, it reads:
NoMethodError in OmniauthCallbacksController#twitter
undefined method `username' for #<User:0x007fa4744561c0>
app/models/user.rb:11:in `from_omniauth'
app/controllers/omniauth_callbacks_controller.rb:3:in `all'
I'm new to Rails, so any help would be much appreciated. Here's a look at my code:
The omniauth_callbacks_controller:
class OmniauthCallbacksController < Devise::OmniauthCallbacksController
def all
user = User.from_omniauth(request.env["omniauth.auth"])
if user.persisted?
flash.notice = "Signed in!"
sign_in_and_redirect user
else
session["devise.user_attributes"] = user.attributes
redirect_to new_user_registration_url
end
end
alias_method :twitter, :all
end
The user model:
class User < ActiveRecord::Base
devise :database_authenticatable, :registerable, :omniauthable,
:recoverable, :rememberable, :trackable, :validatable
attr_accessible :email, :password, :password_confirmation, :remember_me, :username
validates_presence_of :username
validates_uniqueness_of :username
def self.from_omniauth(auth)
where(auth.slice(:provider, :uid)).first_or_create do |user|
user.provider = auth.provider
user.uid = auth.uid
user.username = auth.info.nickname
end
end
def self.new_with_session(params, session)
if session["devise.user_attributes"]
new(session["devise.user_attributes"], without_protection: true) do |user|
user.attributes = params
user.valid?
end
else
super
end
end
def password_required?
super && provider.blank?
end
def update_with_password(params, *options)
if encrypted_password.blank?
update_attributes(params, *options)
else
super
end
end
end

You need to add a username column to your users table.
I can't seem to get CanCan working. This has turned out to be quite frustrating, especially when I have followed the rule book and tried, seemingly, all the tricks under the sun to get it to work.
I am using Rails 3.1.2, Devise 2.1.2, and CanCan 1.6.8. I set-up a separate role model as described by RyanB here.
This is my code.
1) ability.rb
class Ability
include CanCan::Ability
def initializer(user)
user ||= User.new # For users with no account
if (user.has_role?(:admin)) || (user.has_role?(:mod))
can :manage, :all
elsif user.has_role?(:registered)
can :read, :all
can :create, :all
can :update, Question do |question|
question.try(:user) == (user || user.has_role?(:admin) || user.has_role?(:mod))
end
can :destroy, Question do |question|
question.try(:user) == (user || user.has_role?(:admin) || user.has_role?(:mod))
end
else
can :read, :all
end
end
end
2) has_role? definition in user.rb
def has_role?(role_sym)
roles.any? { |r| r.name.underscore.to_sym == role_sym }
end
3) Controller before filters
before_filter :authenticate_user!, :except => :show
load_and_authorize_resource
skip_authorize_resource :only => :show
Authorizing any controller with CanCan results in the same error on all actions.

Okay, it seems, I did not followed ALL the rules of the rule book. Although I cannot see how this could be a problem. To get this working, I deleted my ability.rb file that I created manually, and used the rails g cancan:ability command to generate the same file in the same directory, and used the same code. And now it works like a charm.
I just installed delayed job on my little Rails 3.2 app. Here is the controller where I use it:
require 'waveform'
class MixesController < ApplicationController
def index
end
def new
#mix = Mix.new
end
def create
#mix = Mix.new(params[:mix])
if #mix.save
options = {
method: :rms,
width: 1800,
height: 280,
background_color: "#ffffff",
color: "#3333ff",
force: true,
quiet: true
}
waveform = "./public/waveforms/#{File.basename(#mix.sound_file.to_s, File.extname(#mix.sound_file.to_s))}.png"
::Waveform.new("./public" + #mix.sound_file.to_s, nil).delay.generate(waveform, options)
flash[:success] = "Mix successfully uploaded"
redirect_to mix_url(#mix)
else
render :new
end
end
def show
#mix = Mix.find(params[:id])
end
end
I get an error saying: undefined methodname' for nil:NilClass`, here is the full stack trace:

Does anyone know why I am getting this error please?
This is happening because the system is trying to turn nil into a value that can be stored in YAML and is failing.
Looking at your code, I expect that is because you are passing a nil object into the variables passed to Waveform.new (the method whose operation is being delayed). The variables passed to new will need to be stored until delayed job is ready to run the process, and I expect they are stored as YAML.
Can you refactor Waveform to either make the second attribute optional (so its value doesn't have to be preserved)
::Waveform.new("./public" + #mix.sound_file.to_s).delay.generate(waveform, options)
or use something else to have the same meaning as nil. For example, pass in the symbol :none. Then the line becomes:
::Waveform.new("./public" + #mix.sound_file.to_s, :none).delay.generate(waveform, options)
