Routes

小心地使用 Match（Rails 3 已实现）

Rails 3 提供了 match 方法供我们自定义 routes，然而我们要小心使用它以避免“跨站脚本攻击”（XSS Attack）。比如像这样的 routes：

注：（r3 代表 Rails 3，r4 代表 Rails 4）

# routes.rb

useradd nagios
mkdir -p /opt/install_file
cd /opt/install_file
scp 10.103.13.148:/opt/install_file/nagios-plugins-1.5.tar.gz /opt/install_file
scp 10.103.13.148:/opt/install_file/nrpe-2.15.tar.gz /opt/install_file
tar xvfz nagios-plugins-1.5.tar.gz
cd nagios-plugins-1.5
./configure --prefix=/opt/nagios
make && make install
chown nagios.nagios /opt/nagios

Fibur

Fibur is a library that allows concurrency during Ruby I/O operations without needing to make use of callback systems. Traditionally in Ruby, to achieve concurrency during blocking I/O operations, programmers would make use of Fibers and callbacks. Fibur eliminates the need for wrapping your I/O calls with Fibers and a callback. It allows you to write your blocking I/O calls the way you normally would, and still have concurrent execution during those I/O calls.

Example

Say you have a method that fetches data from a network resource:
