| Module | Puma::Const |
| In: |
lib/puma/const.rb
|
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.
The constants are frozen because Hash#[]= when called with a String key dups the String UNLESS the String is frozen. This saves us therefore 2 object allocations when creating the env hash later.
While Puma does try to emulate the CGI/1.2 protocol, it does not use the REMOTE_IDENT, REMOTE_USER, or REMOTE_HOST parameters since those are either a security problem or too taxing on performance.
| PUMA_VERSION | = | VERSION = "2.4.0".freeze | ||
| CODE_NAME | = | "Crunchy Munchy Lunchy" | ||
| FAST_TRACK_KA_TIMEOUT | = | 0.2 | ||
| PERSISTENT_TIMEOUT | = | 20 | The default number of seconds for another request within a persistent session. | |
| FIRST_DATA_TIMEOUT | = | 30 | The default number of seconds to wait until we get the first data for the request | |
| DATE | = | "Date".freeze | ||
| SCRIPT_NAME | = | "SCRIPT_NAME".freeze | ||
| REQUEST_URI | = | 'REQUEST_URI'.freeze | The original URI requested by the client. | |

| PUMA_TMP_BASE | = | "puma".freeze | ||
| ERROR_400_RESPONSE | = | "HTTP/1.1 400 Bad Request\r\n\r\n" | Indicate that we couldn‘t parse the request | |
| ERROR_404_RESPONSE | = | "HTTP/1.1 404 Not Found\r\nConnection: close\r\nServer: Puma #{PUMA_VERSION}\r\n\r\nNOT FOUND".freeze | The standard empty 404 response for bad requests. Use Error4040Handler for custom stuff. | |
| CONTENT_LENGTH | = | "CONTENT_LENGTH".freeze | ||
| ERROR_500_RESPONSE | = | "HTTP/1.1 500 Internal Server Error\r\n\r\n" | Indicate that there was an internal error, obviously. | |

| CHUNK_SIZE | = | 16 * 1024 | The basic max request size we‘ll try to read. | |
| MAX_HEADER | = | 1024 * (80 + 32) | 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. | |
| MAX_BODY | = | MAX_HEADER | Maximum request body size before it is moved out of memory and into a tempfile for reading. | |
