Module: Unicorn::Const

Defined in:

lib/unicorn/const.rb

Overview

Frequently used constants when constructing requests or responses. Many times the constant just refers to a string with the same contents. Using these constants gave about a 3% to 10% performance improvement over using the strings directly. Symbols did not really improve things much compared to constants.

Constant Summary

UNICORN_VERSION =

"0.93.5"

DEFAULT_HOST =

default TCP listen host address

"0.0.0.0"

DEFAULT_PORT =

default TCP listen port

8080

DEFAULT_LISTEN =

"#{DEFAULT_HOST}:#{DEFAULT_PORT}"

CHUNK_SIZE =

The basic max request size we’ll try to read.

(16 * 1024)

MAX_HEADER =

This is the maximum header that is allowed before a client is booted. The parser detects this, but we’d also like to do this as well.

1024 * (80 + 32)

MAX_BODY =

Maximum request body size before it is moved out of memory and into a tempfile for reading.

MAX_HEADER

ERROR_400_RESPONSE =

common errors we’ll send back

"HTTP/1.1 400 Bad Request\r\n\r\n"

ERROR_500_RESPONSE =

"HTTP/1.1 500 Internal Server Error\r\n\r\n"

EXPECT_100_RESPONSE =

"HTTP/1.1 100 Continue\r\n\r\n"

REMOTE_ADDR =

A frozen format for this is about 15% faster

"REMOTE_ADDR".freeze

HTTP_EXPECT =

"HTTP_EXPECT".freeze

RACK_INPUT =

"rack.input".freeze
