When I open a certificate with OpenSSL::PKCS12, I lose the connection with my database and occur the error: PG::ConnectionBad: PQconsumeInput() SSL error: key values mismatch.
I'm doing this:
myuser#developer:~/myapp$ rails c
2.2.3 :001 > OpenSSL::PKCS12.new File.read('/local/to/mycert.pfx'), 'PASSWORD'

After this I lose the connection:

I perceive that this occurs when the method ca_certs is not null.

Has anyone had this problem?
I encountered this same problem today. After a long search I came across this thread. Seems like a bug in OpenSSL library/extension. Because opening a certificate and talking to a DB happen in a single thread, the connection gets screwed up. I still haven't figured out all details but a workaround is to open the certificate in it's own thread, like:
pkcs = nil
Thread.new { pkcs = OpenSSL::PKCS12.new File.read('/local/to/mycert.pfx'), 'PASSWORD' }.join
Hope that helps :)

This issue is fixed in the 5-0-stable branch.
Solution:
gem 'rails', github: "rails/rails", branch: '5-0-stable'
and bundle update rails until they release a new gem version.
I'm trying to download all of my class notes from coursera. I figured that since I'm learning ruby this would be a good practice exercise, downloading all the PDFs they have for future use. Unfortunately though, I'm getting an exception saying ruby can't connect for some reason. Here is my code:
require 'net/http'
module Coursera
class Downloader
attr_accessor :page_url
attr_accessor :destination_directory
attr_accessor :cookie
def initialize(page_url,dest,cookie)
#page_url=page_url
#destination_directory = dest
#cookie=cookie
end
def download
puts #page_url
request = Net::HTTP::Get.new(#page_url)
puts #cookie.encoding
request['Cookie']=#cookie
# the line below is where the exception is thrown
res = Net::HTTP.start(#page_url.hostname, use_ssl=true,#page_url.port) {|http|
http.request(request)
}
html_page = res.body
pattern = /http[^\"]+\.pdf/
i=0
while (match = pattern.match(html_page,i)) != nil do
# 0 is the entire string.
url_string = match[0]
# make sure that 'i' is updated
i = match.begin(0)+1
# we want just the name of the file.
j = url_string.rindex("/")
filename = url_string[j+1..url_string.length]
destination = #destination_directory+"\\"+filename
# I want to download that resource to that file.
uri = URI(url_string)
res = Net::HTTP.get_response(uri)
# write that body to the file
f=File.new(destination,mode="w")
f.print(res.body)
end
end
end
end
page_url_string = 'https://class.coursera.org/datasci-002/lecture'
puts page_url_string.encoding
dest='C:\\Users\\michael\\training material\\data_science'
page_url=URI(page_url_string)
# I copied this from my browsers developer tools, I'm omitting it since
# it's long and has my session key in it
cookie="..."
downloader = Coursera::Downloader.new(page_url,dest,cookie)
downloader.download

I was following instructions here to write all the HTTP code. As far as I can see I'm following them ver-batim.
I'm using Windows 7, ruby 2.0.0p481, and Aptana Studio 3. When I copy the url into my browser it goes straight to the page without a problem. When I look at the request headers in my browser for that url, I don't see anything else I think I'm missing. I also tried setting the Host and Referer request headers, it made no difference.
I am out of ideas, and have already searched Stack Overflow for similar questions but that didn't help. Please let me know what I'm missing.
So, I had this same error message with a different project and the problem was that my machine literally couldn't connect to the IP / Port. Have you tried connecting with curl? If it works in your browser, it could be using a proxy or something to actually get there. Testing the URL with curl solved the problem for me.
Upgrade steps were performed as mentioned in http://guides.rubyonrails.org/3_2_release_notes.html

The error is happening inside ActiveSupport::BufferedLogger#add method call and you appear to be monkey-patching this class. The internals of ActiveSupport::BufferedLogger have likely changing between the versions of Rails you're using.
Try removing all of the ActiveSupport::BufferedLogger code from your environment.rb to work past this error and get your app running. Then, if you still need the monkeypatch (don't know why), you'd have to rewrite it on top of the newer version of the class.
I am not using rails, and I'm trying to use ActiveRecord to make it easier to work with an existing database. This is just a script so I have no database.yml or any other files. I've set up my database connection using
ActiveRecord::Base.establish_connection(
adapter: 'postgresql',
host: 'thehosthere',
database: 'management',
username: 'management_readonly',
password: '',
port: '5432'
)
I'm not really familiar with databases, so I'll just state what I know about this one. There are quite a few schemas. The schema I'm interested in is the management schema that has the table "host". I've created a class Host in the script like this:
class Host < ActiveRecord::Base
self.table_name = "host"
end
I'm then trying to pull all rows that match the criteria with this query and to store it into an array.
servers = Host.where(:realm => 'stage', :status => 'UP').pluck(:hostname)
but I am getting this error every single time.

I don't really understand why this is happening, so I tried to see what the database looks like with this command ActiveRecord::Base.connection.tables but all I got was an empty array. I'm not sure what could be happening. I'm obviously doing something wrong, I just can't figure out what. Keep in mind, this is all in a single file script.
Edit:
So I can see the schemas if I use ActiveRecord::Base.connection.schema_names. This gives me an array => ["db_stats", "management", "management_audit", "public"] Using pgadmin, I know that the table I want is in management, so how do I access that?
Try adding schema_search_path when you call establish_connection:
ActiveRecord::Base.establish_connection(
adapter: 'postgresql',
host: 'thehosthere',
database: 'management',
username: 'management_readonly',
password: '',
port: 5432,
schema_search_path: 'management' # <-- ???
)
I'm a ruby noob and I'm trying to process some blog posts using Sequel and the data_objects adapter:
DB = Sequel.connect('do:mysql://user:pass#localhost/database')
db[posts_query].each do |post|
puts post
end
But I get Sequel::InvalidValue exception, complaining about the date column:
/usr/lib/ruby/1.9.1/time.rb:202:in `local': ArgumentError: argument out of range (Sequel::InvalidValue)
from /usr/lib/ruby/1.9.1/time.rb:202:in `make_time'
from /usr/lib/ruby/1.9.1/time.rb:271:in `parse'
from /var/lib/gems/1.9.1/gems/sequel-3.42.0/lib/sequel/core.rb:295:in `string_to_datetime'
I tried to catch the exception:
begin
db[posts_query].each do |post|
puts post
end
rescue Sequel::InvalidValue => e
puts e.inspect
end
but that doesn't help much.
How can I find out which row has the incorrect value?
Also, is there a way to do this iteration, such that I can catch the exception but continue to loop over the remaining rows?
Update:
I switched to the mysql2 adapter and now I can at least see the invalid date:

Can you post more of the backtrace? You need to see what is calling string_to_datetime.
Also, I would recommend against using the do/mysql adapter unless you have specific needs that require it. Use the mysql or mysql2 adapter instead. If the error is being caused by bogus datetimes in your MySQL database, then you may want to use the mysql2 adapter or use the mysql adapter and set DB.convert_invalid_date_time = nil.
