Configuration for the openssl library.
Many system’s installation of openssl library will depend on your system configuration. See the value of OpenSSL::Config::DEFAULT_CONFIG_FILE for the location of the file for your host.
General error for openssl library configuration files. Including formatting, parsing errors, etc.

Thrown when PTY::check is called for a pid that represents a process that has exited.
Socket::AncillaryData represents the ancillary data (control information) used by sendmsg and recvmsg system call. It contains socket family, control message (cmsg) level, cmsg type and cmsg data.
Zlib::GzipWriter is a class for writing gzipped files. GzipWriter should be used with an instance of IO, or IO-like, object.
Following two example generate the same result.
Zlib::GzipWriter.open('hoge.gz') do |gz| gz.write 'jugemu jugemu gokou no surikire...' end File.open('hoge.gz', 'w') do |f| gz = Zlib::GzipWriter.new(f) gz.write 'jugemu jugemu gokou no surikire...' gz.close end
To make like gzip(1) does, run following:
orig = 'hoge.txt' Zlib::GzipWriter.open('hoge.gz') do |gz| gz.mtime = File.mtime(orig) gz.orig_name = orig gz.write IO.binread(orig) end
NOTE: Due to the limitation of Ruby’s finalizer, you must explicitly close GzipWriter objects by Zlib::GzipWriter#close etc. Otherwise, GzipWriter will be not able to write the gzip footer and will generate a broken gzip file.

This class is the base class for Net::HTTP response classes.
Method Net::HTTP.get_response returns an instance of one of the subclasses of Net::HTTPResponse:
Net::HTTP.get_response(uri) # => #<Net::HTTPOK 200 OK readbody=true> Net::HTTP.get_response(hostname, '/nosuch') # => #<Net::HTTPNotFound 404 Not Found readbody=true>
As does method Net::HTTP#request:
req = Net::HTTP::Get.new(uri) Net::HTTP.start(hostname) do |http| http.request(req) end # => #<Net::HTTPOK 200 OK readbody=true>
Class Net::HTTPResponse includes module Net::HTTPHeader, which provides access to response header values via (among others):
Hash-like method [].
Specific reader methods, such as content_type.
Examples:
res = Net::HTTP.get_response(uri) # => #<Net::HTTPOK 200 OK readbody=true> res['Content-Type'] # => "text/html; charset=UTF-8" res.content_type # => "text/html"
Class Net::HTTPResponse has a subclass for each HTTP status code. You can look up the response class for a given code:
Net::HTTPResponse::CODE_TO_OBJ['200'] # => Net::HTTPOK Net::HTTPResponse::CODE_TO_OBJ['400'] # => Net::HTTPBadRequest Net::HTTPResponse::CODE_TO_OBJ['404'] # => Net::HTTPNotFound
And you can retrieve the status code for a response object:
Net::HTTP.get_response(uri).code # => "200" Net::HTTP.get_response(hostname, '/nosuch').code # => "404"
The response subclasses (indentation shows class hierarchy):
Net::HTTPUnknownResponse (for unhandled HTTP extensions).

Response class for Switching Protocol responses (status code 101).
The <tt>Switching Protocol<tt> response indicates that the server has received a request to switch protocols, and has agreed to do so.
References:
Response class for Early Hints responses (status code 103).
The Early Hints indicates that the server has received and is processing the request, and contains certain headers; the final response is not available yet.
References:
Response class for Accepted responses (status code 202).
The Accepted response indicates that the server has received and is processing a request, but the processing has not yet been completed.
References:
Response class for No Content responses (status code 204).
The No Content response indicates that the server successfully processed the request, and is not returning any content.
References:
Response class for Reset Content responses (status code 205).
The Reset Content response indicates that the server successfully processed the request, asks that the client reset its document view, and is not returning any content.
References:
Response class for Found responses (status code 302).
The Found response indicates that the client should look at (browse to) another URL.
References:
Response class for Temporary Redirect responses (status code 307).
The request should be repeated with another URI; however, future requests should still use the original URI.
References:
Response class for Payment Required responses (status code 402).
Reserved for future use.
