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

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:

Railties 3.1 Beta 1

The -j option of the application generator accepts an arbitrary string. If passed "foo", the gem "foo-rails" is added to the Gemfile, and the application JavaScript manifest requires "foo" and "foo_ujs". As of this writing "prototype-rails" and "jquery-rails" exist and provide those files via the asset pipeline. Default is "jquery". [fxn]
jQuery is no longer vendored, it is provided from now on by the jquery-rails gem. [fxn]
Prototype and Scriptaculous are no longer vendored, they are provided from now on by the prototype-rails gem. [fxn]
The scaffold controller will now produce SCSS file if Sass is available [Prem Sichanugrist]

	If you want, I can try and help with pointers as to how to improve the indexing speed you get. Its quite easy to really increase it by using some simple guidelines, for example:

	- Use create in the index API (assuming you can).
	- Relax the real time aspect from 1 second to something a bit higher (index.engine.robin.refresh_interval).
	- Increase the indexing buffer size (indices.memory.index_buffer_size), it defaults to the value 10% which is 10% of the heap.
	- Increase the number of dirty operations that trigger automatic flush (so the translog won't get really big, even though its FS based) by setting index.translog.flush_threshold (defaults to 5000).
	- Increase the memory allocated to elasticsearch node. By default its 1g.
	- Start with a lower replica count (even 0), and then once the bulk loading is done, increate it to the value you want it to be using the update_settings API. This will improve things as possibly less shards will be allocated to each machine.
	- Increase the number of machines you have so

	# The home folder for airflow, default is ~/airflow
	airflow_home = /Users/p1nox/airflow

	# The folder where your airflow pipelines live, most likely a
	# subfolder in a code repository
	dags_folder = /Users/p1nox/airflow/dags

	# The folder where airflow should store its log files. This location
	base_log_folder = /Users/p1nox/airflow/logs

	if nginx_uri == "/_access_token" or nginx_uri == "/_me" then
	ngx.exit(403)
