使用tiny_TDS在rails中连接到SQL-Azure:[BUG]分段错误 [英] Connecting to SQL-Azure in rails using tiny_TDS: [BUG] Segmentation fault

问题描述

我们试图让Rails与Azure上的sqlserver数据库对话，我们使用openssl和libiconv安装freeTDS:

We're trying to get rails to talk to a sqlserver db on Azure, we install freeTDS with openssl and libiconv:

./configure --prefix=/usr/local --with-libiconv-prefix=DIR --with-openssl=DIR
make
make install

然后我们将gem_TDS和activerecord-sqlserver-adapter添加到gemfile:

We then add tiny_TDS and activerecord-sqlserver-adapter to the gemfile:

gem 'tiny_tds'
gem 'activerecord-sqlserver-adapter'

$ bundle install

配置数据库:

development:  
  adapter: sqlserver
  host: xxxxxxx.database.windows.net
  mode: DBLIB
  port: 1433
  database: xxxxx
  username: xxxxxxxx
  password: x
  azure: true

运行服务器:

$ rails s

到目前为止，一切正常，但是一旦您访问该站点，ruby崩溃.

Everything works great up until this point, but as soon as you visit the site ruby crashes.

我们尝试了红宝石的几种版本:1.9.2-p318，1.9.2-p320，1.9.3-p125.所有这些都存在相同的错误.

We've tried several versions of ruby: 1.9.2-p318, 1.9.2-p320, 1.9.3-p125. Same error with all of them.

这是在ubuntu 11.10上使用rvm和FreeTDS-0.9.1.

This is on ubuntu 11.10 using rvm and FreeTDS-0.9.1.

有任何解决方法的想法吗?

Any Ideas on a workaround?

我在途中某个地方犯了错误吗?

Have I made an error somewhere along the way?

IRB的输出

require 'tiny_tds'
client = TinyTds::Client.new(:username =>'[e-mail]', :password => 'XXXXXXX', :host => 'XXXXXX.database.windows.net',  :mode => 'DBLIB', :azure => 'true')
SystemStackError: stack level too deep from /home/martinr/.rvm/rubies/ruby-1.9.2-p320/lib/ruby/1.9.1/irb/workspace.rb:80
Maybe IRB bug!!

这似乎是红宝石本身的错误:

It seems to be a bug with ruby itself:

/home/martinr/.rvm/gems/ruby-1.9.2-p320/gems/tiny_tds-0.5.1/lib/tiny_tds/client.rb:68: [BUG] Segmentation fault (core dumped)

推荐答案

该错误似乎是由用户名username@servername

The error seems to be caused by having a username username@servername

当您删除@severname部分时，红宝石不再崩溃

When you remove the @severname part, ruby no longer crashes
