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"]
Returns a new Fiddle::Function instance at the memory address of the given name function.
Raises a DLError if the name doesn’t exist.
argtype is an Array of arguments, passed to the name function.
ctype is the return type of the function
call_type is the ABI of the function
See also Fiddle:Function.new
See Fiddle::CompositeHandler.sym and Fiddle::Handler.sym
Returns a new closure wrapper for the name function.
ctype is the return type of the function
argtype is an Array of arguments, passed to the callback function
call_type is the abi of the closure
block is passed to the callback

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>
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.
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”.
Be careful that you don’t overwrite OpenSSL::SSL::OP_NO_{SSL,TLS}v* options by options= once you have called min_version= or max_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.
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.
Returns a String representing the SSL/TLS version that was negotiated for the connection, for example “TLSv1.2”.
Returns true if a reused session was negotiated during the handshake.
Parses the UTF-8 string representation of a distinguished name, according to RFC 2253.
See also to_utf8 for the opposite operation.
Create an exception with class klass and message
Takes a token and gets the next token in the Negotiate authentication chain. Token can be Base64 encoded or not. The token can include the “Negotiate” header and it will be stripped. Does not indicate if SEC_I_CONTINUE or SEC_E_OK was returned. Token returned is Base64 encoded w/ all new lines removed.
