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 in the non-blocking manner.
If there is buffered data, it is flushed first. This may block.
write_nonblock returns number of bytes written to the SSL connection.
When no data can be written without blocking it raises OpenSSL::SSL::SSLError extended by IO::WaitReadable or IO::WaitWritable.
IO::WaitReadable means SSL needs to read internally so write_nonblock should be called again after the underlying IO is readable.
IO::WaitWritable means SSL needs to write internally so write_nonblock should be called again after underlying IO is writable.
So OpenSSL::Buffering#write_nonblock needs two rescue clause as follows.
# emulates blocking write. begin result = ssl.write_nonblock(str) rescue IO::WaitReadable IO.select([io]) retry rescue IO::WaitWritable IO.select(nil, [io]) retry end
Note that one reason that write_nonblock reads from the underlying IO is when the peer requests a new TLS/SSL handshake. See the openssl FAQ for more details. www.openssl.org/support/faq.html
By specifying a keyword argument exception to false, you can indicate that write_nonblock should not raise an IO::Wait*able exception, but return the symbol :wait_writable or :wait_readable instead.
A wrapper class to use a StringIO object as the body and switch to a TempFile when the passed threshold is passed. Initialize the data from the query.
Handles multipart forms (in particular, forms that involve file uploads). Reads query parameters in the @params field, and cookies into @cookies.
Generate an Image Button Input element as a string.
src is the URL of the image to use for the button. name is the input name. alt is the alternative text for the image.
Alternatively, the attributes can be specified as a hash.
image_button("url") # <INPUT TYPE="image" SRC="url"> image_button("url", "name", "string") # <INPUT TYPE="image" SRC="url" NAME="name" ALT="string"> image_button("SRC" => "url", "ALT" => "string") # <INPUT TYPE="image" SRC="url" ALT="string">
Generate a sequence of radio button Input elements, as a String.
This works the same as checkbox_group(). However, it is not valid to have more than one radiobutton in a group checked.
radio_group("name", "foo", "bar", "baz") # <INPUT TYPE="radio" NAME="name" VALUE="foo">foo # <INPUT TYPE="radio" NAME="name" VALUE="bar">bar # <INPUT TYPE="radio" NAME="name" VALUE="baz">baz radio_group("name", ["foo"], ["bar", true], "baz") # <INPUT TYPE="radio" NAME="name" VALUE="foo">foo # <INPUT TYPE="radio" CHECKED NAME="name" VALUE="bar">bar # <INPUT TYPE="radio" NAME="name" VALUE="baz">baz radio_group("name", ["1", "Foo"], ["2", "Bar", true], "Baz") # <INPUT TYPE="radio" NAME="name" VALUE="1">Foo # <INPUT TYPE="radio" CHECKED NAME="name" VALUE="2">Bar # <INPUT TYPE="radio" NAME="name" VALUE="Baz">Baz radio_group("NAME" => "name", "VALUES" => ["foo", "bar", "baz"]) radio_group("NAME" => "name", "VALUES" => [["foo"], ["bar", true], "baz"]) radio_group("NAME" => "name", "VALUES" => [["1", "Foo"], ["2", "Bar", true], "Baz"])
Returns a Range object representing the value of field 'Content-Range', or nil if no such field exists; see Content-Range response header:
res = Net::HTTP.get_response(hostname, '/todos/1') res['Content-Range'] # => nil res['Content-Range'] = 'bytes 0-499/1000' res['Content-Range'] # => "bytes 0-499/1000" res.content_range # => 0..499
Returns the media type from the value of field 'Content-Type', or nil if no such field exists; see Content-Type response header:
res = Net::HTTP.get_response(hostname, '/todos/1') res['content-type'] # => "application/json; charset=utf-8" res.content_type # => "application/json"
returns “type/subtype” which is MIME Content-Type. It is downcased for canonicalization. Content-Type parameters are stripped.
Initializes instance variable.
A convenience method which is same as follows:
group(1, '#<' + obj.class.name, '>') { ... }
A present standard failsafe for pretty printing any given Object
Enumerates the trusted certificates via Gem::Security::TrustDir.
If response is an HTTP Success (2XX) response, yields the response if a block was given or shows the response body to the user.
If the response was not successful, shows an error to the user including the error_prefix and the response body. If the response was a permanent redirect, shows an error to the user including the redirect location.
Returns true for IPv6 multicast node-local scope address. It returns false otherwise.
Render a template on a new toplevel binding with local variables specified by a Hash object.
Breaks the buffer into lines that are shorter than maxwidth
Returns the value of the local variable symbol.
def foo a = 1 binding.local_variable_get(:a) #=> 1 binding.local_variable_get(:b) #=> NameError end
This method is the short version of the following code:
binding.eval("#{symbol}")
Set local variable named symbol as obj.
def foo a = 1 bind = binding bind.local_variable_set(:a, 2) # set existing local variable `a' bind.local_variable_set(:b, 3) # create new local variable `b' # `b' exists only in binding p bind.local_variable_get(:a) #=> 2 p bind.local_variable_get(:b) #=> 3 p a #=> 2 p b #=> NameError end
This method behaves similarly to the following code:
binding.eval("#{symbol} = #{obj}")
if obj can be dumped in Ruby code.
