Private setter for headers v
.
Constructs the default Hash
of patterns.
possible opt elements:
hash form: :partial_input => true # source buffer may be part of larger source :after_output => true # stop conversion after output before input integer form: Encoding::Converter::PARTIAL_INPUT Encoding::Converter::AFTER_OUTPUT
possible results:
:invalid_byte_sequence :incomplete_input :undefined_conversion :after_output :destination_buffer_full :source_buffer_empty :finished
primitive_convert
converts source_buffer into destination_buffer.
source_buffer should be a string or nil. nil means an empty string.
destination_buffer should be a string.
destination_byteoffset should be an integer or nil. nil means the end of destination_buffer. If it is omitted, nil is assumed.
destination_bytesize should be an integer or nil. nil means unlimited. If it is omitted, nil is assumed.
opt should be nil, a hash or an integer. nil means no flags. If it is omitted, nil is assumed.
primitive_convert
converts the content of source_buffer from beginning and store the result into destination_buffer.
destination_byteoffset and destination_bytesize specify the region which the converted result is stored. destination_byteoffset specifies the start position in destination_buffer in bytes. If destination_byteoffset is nil, destination_buffer.bytesize is used for appending the result. destination_bytesize specifies maximum number of bytes. If destination_bytesize is nil, destination size is unlimited. After conversion, destination_buffer is resized to destination_byteoffset + actually produced number of bytes. Also destination_buffer’s encoding is set to destination_encoding.
primitive_convert
drops the converted part of source_buffer. the dropped part is converted in destination_buffer or buffered in Encoding::Converter
object.
primitive_convert
stops conversion when one of following condition met.
invalid byte sequence found in source buffer (:invalid_byte_sequence) primitive_errinfo
and last_error
methods returns the detail of the error.
unexpected end of source buffer (:incomplete_input) this occur only when :partial_input is not specified. primitive_errinfo
and last_error
methods returns the detail of the error.
character not representable in output encoding (:undefined_conversion) primitive_errinfo
and last_error
methods returns the detail of the error.
after some output is generated, before input is done (:after_output) this occur only when :after_output is specified.
destination buffer is full (:destination_buffer_full) this occur only when destination_bytesize is non-nil.
source buffer is empty (:source_buffer_empty) this occur only when :partial_input is specified.
conversion is finished (:finished)
example:
ec = Encoding::Converter.new("UTF-8", "UTF-16BE") ret = ec.primitive_convert(src="pi", dst="", nil, 100) p [ret, src, dst] #=> [:finished, "", "\x00p\x00i"] ec = Encoding::Converter.new("UTF-8", "UTF-16BE") ret = ec.primitive_convert(src="pi", dst="", nil, 1) p [ret, src, dst] #=> [:destination_buffer_full, "i", "\x00"] ret = ec.primitive_convert(src, dst="", nil, 1) p [ret, src, dst] #=> [:destination_buffer_full, "", "p"] ret = ec.primitive_convert(src, dst="", nil, 1) p [ret, src, dst] #=> [:destination_buffer_full, "", "\x00"] ret = ec.primitive_convert(src, dst="", nil, 1) p [ret, src, dst] #=> [:finished, "", "i"]
Parses multipart form elements according to
http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4.2
Returns a hash of multipart form parameters with bodies of type StringIO
or Tempfile
depending on whether the multipart form element exceeds 10 KB
params[name => body]
Generate a Form element with multipart encoding as a String
.
Multipart encoding is used for forms that include file uploads.
action
is the action to perform. enctype
is the encoding type, which defaults to “multipart/form-data”.
Alternatively, the attributes can be specified as a hash.
multipart_form{ "string" } # <FORM METHOD="post" ENCTYPE="multipart/form-data">string</FORM> multipart_form("url") { "string" } # <FORM METHOD="post" ACTION="url" ENCTYPE="multipart/form-data">string</FORM>
Message to promote available RubyGems update with related gem update command.
Enumerates the outdated local gems yielding the local specification and the latest remote version.
This method may take some time to return as it must check each local gem against the server’s index.
Gets the global do_not_reverse_lookup
flag.
BasicSocket.do_not_reverse_lookup #=> false
Sets the global do_not_reverse_lookup
flag.
The flag is used for initial value of do_not_reverse_lookup
for each socket.
s1 = TCPSocket.new("localhost", 80) p s1.do_not_reverse_lookup #=> true BasicSocket.do_not_reverse_lookup = false s2 = TCPSocket.new("localhost", 80) p s2.do_not_reverse_lookup #=> false p s1.do_not_reverse_lookup #=> true
Gets the do_not_reverse_lookup
flag of basicsocket.
require 'socket' BasicSocket.do_not_reverse_lookup = false TCPSocket.open("www.ruby-lang.org", 80) {|sock| p sock.do_not_reverse_lookup #=> false } BasicSocket.do_not_reverse_lookup = true TCPSocket.open("www.ruby-lang.org", 80) {|sock| p sock.do_not_reverse_lookup #=> true }
Sets the do_not_reverse_lookup
flag of basicsocket.
TCPSocket.open("www.ruby-lang.org", 80) {|sock| p sock.do_not_reverse_lookup #=> true p sock.peeraddr #=> ["AF_INET", 80, "221.186.184.68", "221.186.184.68"] sock.do_not_reverse_lookup = false p sock.peeraddr #=> ["AF_INET", 80, "carbon.ruby-lang.org", "54.163.249.195"] }
Constant time memory comparison for fixed length strings, such as results of HMAC
calculations.
Returns true
if the strings are identical, false
if they are of the same length but not identical. If the length is different, ArgumentError
is raised.
The index to insert activated gem paths into the $LOAD_PATH. The activated gem’s paths are inserted before site lib directory by default.
The iterator version of the strongly_connected_components
method. obj.each_strongly_connected_component
is similar to obj.strongly_connected_components.each
, but modification of obj during the iteration may lead to unexpected results.
each_strongly_connected_component
returns nil
.

The iterator version of the TSort.strongly_connected_components
method.
The graph is represented by each_node and each_child. each_node should have call
method which yields for each node in the graph. each_child should have call
method which takes a node argument and yields for each child node.

Sets the SSL/TLS protocol version for the context. This forces connections to use only the specified protocol version. This is deprecated and only provided for backwards compatibility. Use min_version=
and max_version=
instead.
As the name hints, this used to call the SSL_CTX_set_ssl_version() function which sets the SSL
method used for connections created from the context. As of Ruby/OpenSSL 2.1, this accessor method is implemented to call min_version=
and max_version=
instead.
Sets the lower bound on the supported SSL/TLS protocol version. The version may be specified by an integer constant named OpenSSL::SSL::*_VERSION, a Symbol
, or nil
which means “any version”.
ctx = OpenSSL::SSL::SSLContext.new ctx.min_version = OpenSSL::SSL::TLS1_1_VERSION ctx.max_version = OpenSSL::SSL::TLS1_2_VERSION sock = OpenSSL::SSL::SSLSocket.new(tcp_sock, ctx) sock.connect # Initiates a connection using either TLS 1.1 or TLS 1.2
Sets the upper bound of the supported SSL/TLS protocol version. See min_version=
for the possible values.
