easy_captcha's Issues

Security bug! Captcha verify will skip when Memcached crashed.

Today, I found Captcha verify not effect when the captcha is wrong（My code logic is right, before this, it can work）.

So, I check the Rails logs, I found Memcached was crashed, and when I restart it, Captcha verify has working.

Looks like when easy_captcha connect read cache failed , it will skip validation.

PLATFORM == 'java' logic in gemspec doesn't work

This cf01185#diff-f68d7ca69ff14c5e89e06e69172d56c1R36 doesn't do what it's supposed to.

According to e.g. rubygems/rubygems#1662 (comment), or the much older (and semi-broken) http://blog.mattwynne.net/2011/04/26/targeting-multiple-platforms-jruby-etc-with-a-rubygems-gemspec/ the gemspec is executed once (by rubygems) and then serialized.

Can not work with jruby + rmagick4j

undefined local variable or method `check_destroyed' for #<Magick::Image:0x48097a51>

jruby 1.7.3 (1.9.3p385)
rmagick4j 0.3.7
easy_captcha 0.6.3

Troubles with rails version

Hi!
i get this on bundle install:

Bundler could not find compatible versions for gem "rails":
In Gemfile:
easy_captcha depends on
rails (~> 3.0.0)

rails (3.1.0.rc5)

Maybe more flexible something like: >=3.0.0 and < 3.1??

Disable validation in test environment

There should be an option to disable the validation entirely when testing (make it always return true) in the test environment or in the config file. I'm using Rspec.
For now in my controller specs i just use "controller.stub(:captcha_valid?).and_return(true)" but for some reason that doesn't work in my feature spec ... and I tried writing it in many ways:
allow(UserRegistrationController).to receive(:captcha_valid?).and_return true
UserRegistrationController.stub(:captcha_valid?).and_return(true)
... not working.
Some help would be greatly appreciated.
Thank you,
Dan

After upgrade to Rails 3.2.0 easy_captcha returns HTTP error code 500

Hi folks,
after upgrade to Rails 3.2.0 my application stopped rendering captchas. I found it was returning HTTP error code 500.

Here is a small workaround:

edit lib/easy_captcha/routes.rb in the easy_captcha gem and add the action explicitly into match clause
match "captcha" => EasyCaptcha::Controller, :action => "captcha", :via => :get

I hope it will help somebody.
-ms

session is nil

captcha_valid? always return false

Rails 3.2.11
No sesseion[:captcha]

Is there any way to get rid of them?

MAINTAINED FORK: K-and-R/easy_captcha (gem `kandr-easy_captcha`)

I have forked this and am working to improve its code quality and test coverage, as well as address some of the issues.

https://rubygems.org/gems/kandr-easy_captcha

As my fork is a fork, I cannot create issues there. I wish to keep it as a connected fork rather than delete the fork and recreate it as a separately cloned repo.

Should anyone have any changes that are needed, please feel free to tag me or message directly.
