Checks the path v component for RFC2396 compliance and against the URI::Parser Regexp for :ABS_PATH and :REL_PATH.

Can not have a opaque component defined, with a path component defined.

Protected setter for the path component v.

Checks the opaque v component for RFC2396 compliance and against the URI::Parser Regexp for :OPAQUE.

Can not have a host, port, user, or path component defined, with an opaque component defined.

Protected setter for the opaque component v.

See also URI::Generic.opaque=.

Merges a base path base, with relative path rel, returns a modified base path.

The content-length header

The content-type header

This method provides the metavariables defined by the revision 3 of “The WWW Common Gateway Interface Version 1.1” To browse the current document of CGI Version 1.1, see below: tools.ietf.org/html/rfc3875

The content-length header

Sets the content-length header to len

The content-type header

Sets the content-type header to type

Finds a servlet for path

Adds server as a virtual host.

Creates the HTTPResponse used when handling the HTTP request. Can be overridden by subclasses.

Calls the given block once for each key, value pair in the database.

Returns self.

Returns the one-character string which cause Encoding::UndefinedConversionError.

ec = Encoding::Converter.new("ISO-8859-1", "EUC-JP")
begin
  ec.convert("\xa0")
rescue Encoding::UndefinedConversionError
  puts $!.error_char.dump   #=> "\xC2\xA0"
  p $!.error_char.encoding  #=> #<Encoding:UTF-8>
end

Returns the corresponding ASCII compatible encoding.

Returns nil if the argument is an ASCII compatible encoding.

“corresponding ASCII compatible encoding” is an ASCII compatible encoding which can represents exactly the same characters as the given ASCII incompatible encoding. So, no conversion undefined error occurs when converting between the two encodings.

Encoding::Converter.asciicompat_encoding("ISO-2022-JP") #=> #<Encoding:stateless-ISO-2022-JP>
Encoding::Converter.asciicompat_encoding("UTF-16BE") #=> #<Encoding:UTF-8>
Encoding::Converter.asciicompat_encoding("UTF-8") #=> nil

Inserts string into the encoding converter. The string will be converted to the destination encoding and output on later conversions.

If the destination encoding is stateful, string is converted according to the state and the state is updated.

This method should be used only when a conversion error occurs.

ec = Encoding::Converter.new("utf-8", "iso-8859-1")
src = "HIRAGANA LETTER A is \u{3042}."
dst = ""
p ec.primitive_convert(src, dst)    #=> :undefined_conversion
puts "[#{dst.dump}, #{src.dump}]"   #=> ["HIRAGANA LETTER A is ", "."]
ec.insert_output("<err>")
p ec.primitive_convert(src, dst)    #=> :finished
puts "[#{dst.dump}, #{src.dump}]"   #=> ["HIRAGANA LETTER A is <err>.", ""]

ec = Encoding::Converter.new("utf-8", "iso-2022-jp")
src = "\u{306F 3041 3068 2661 3002}" # U+2661 is not representable in iso-2022-jp
dst = ""
p ec.primitive_convert(src, dst)    #=> :undefined_conversion
puts "[#{dst.dump}, #{src.dump}]"   #=> ["\e$B$O$!$H".force_encoding("ISO-2022-JP"), "\xE3\x80\x82"]
ec.insert_output "?"                # state change required to output "?".
p ec.primitive_convert(src, dst)    #=> :finished
puts "[#{dst.dump}, #{src.dump}]"   #=> ["\e$B$O$!$H\e(B?\e$B!#\e(B".force_encoding("ISO-2022-JP"), ""]

Returns a new instance of the C struct with the value ty at the addr address.

Returns a new Fiddle::Pointer instance at the memory address of the given name symbol.

Raises a DLError if the name doesn’t exist.

See Fiddle::CompositeHandler.sym and Fiddle::Handle.sym

Similar to read, but raises EOFError at end of string unless the +exception: false+ option is passed in.

Consumes size bytes from the buffer

Reads at most maxlen bytes in the non-blocking manner.

When no data can be read without blocking it raises OpenSSL::SSL::SSLError extended by IO::WaitReadable or IO::WaitWritable.

IO::WaitReadable means SSL needs to read internally so read_nonblock should be called again when the underlying IO is readable.

IO::WaitWritable means SSL needs to write internally so read_nonblock should be called again after the underlying IO is writable.

OpenSSL::Buffering#read_nonblock needs two rescue clause as follows:

# emulates blocking read (readpartial).
begin
  result = ssl.read_nonblock(maxlen)
rescue IO::WaitReadable
  IO.select([io])
  retry
rescue IO::WaitWritable
  IO.select(nil, [io])
  retry
end

Note that one reason that read_nonblock writes to the underlying IO is when the peer requests a new TLS/SSL handshake. See openssl the FAQ for more details. www.openssl.org/support/faq.html

By specifying a keyword argument exception to false, you can indicate that read_nonblock should not raise an IO::Wait*able exception, but return the symbol :wait_writable or :wait_readable instead. At EOF, it will return nil instead of raising EOFError.

Writes s to the buffer. When the buffer is full or sync is true the buffer is flushed to the underlying socket.
