Deflates data
Constructs a Gem::Resolver::DependencyRequest from a Gem::Dependency dep, a from_name and from_version requesting the dependency and a parent DependencyRequest
Uninstalls gem spec
Given a gem file’s contents, validates against its own MD5 checksum
Contents of the gem file
start a job
check the user and password.
If password is not provided, then user is split, using URI::Generic.split_userinfo, to pull user and +password.
see also URI::Generic.check_user, URI::Generic.check_password
protect setter for the user component, and password if available. (with validation)
see also URI::Generic.userinfo=
returns the userinfo ui as user, password if properly formatted as ‘user:password’
check the host v component for RFC2396 compliance and against the URI::Parser Regexp for :HOST
Can not have a registry or opaque component defined, with a host component defined.
The client’s IP address
The response’s HTTP status line
Adds server as a virtual host.
Returns the destination encoding as an encoding object.
Returns the destination encoding as an encoding object.
Returns the destination encoding as an Encoding object.
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 an exception object for the last conversion. Returns nil if the last conversion did not produce an error.
“error” means that Encoding::InvalidByteSequenceError and Encoding::UndefinedConversionError for Encoding::Converter#convert and :invalid_byte_sequence, :incomplete_input and :undefined_conversion for Encoding::Converter#primitive_convert.
ec = Encoding::Converter.new("utf-8", "iso-8859-1") p ec.primitive_convert(src="\xf1abcd", dst="") #=> :invalid_byte_sequence p ec.last_error #=> #<Encoding::InvalidByteSequenceError: "\xF1" followed by "a" on UTF-8> p ec.primitive_convert(src, dst, nil, 1) #=> :destination_buffer_full p ec.last_error #=> nil
Returns the length of the hash value of the digest.
This method should be overridden by each implementation subclass. If not, digest_obj.digest().length() is returned.
Writes s to the buffer. When the buffer is full or sync is true the buffer is flushed to the underlying socket.
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.
