Return an DRb::DRbSSLSocket instance as a client-side connection, with the SSL connected. This is called from DRb::start_service or while connecting to a remote object:
DRb.start_service 'drbssl://localhost:0', front, config
uri is the URI we are connected to, 'drbssl://localhost:0' above, config is our configuration. Either a Hash or DRb::DRbSSLSocket::SSLConfig
Returns an array of the eigenvectors
Symmetric Householder reduction to tridiagonal form.
Symmetric tridiagonal QL algorithm.
Returns true if U, and hence A, is singular.
A synonym for FTP.new, but with a mandatory host parameter.
If a block is given, it is passed the FTP object, which will be closed when the block finishes, or when an exception is raised.
A setter to toggle transfers in binary mode. newmode is either true or false
Establishes an FTP connection to host, optionally overriding the default port. If the environment variable SOCKS_SERVER is set, sets up the connection through a SOCKS proxy. Raises an exception (typically Errno::ECONNREFUSED) if the connection cannot be established.
Sends a command and returns the response.
Puts the connection into binary (image) mode, issues the given command, and fetches the data returned, passing it to the associated block in chunks of blocksize characters. Note that cmd is a server command (such as “RETR myfile”).
Puts the connection into binary (image) mode, issues the given server-side command (such as “STOR myfile”), and sends the contents of the file named file to the server. If the optional block is given, it also passes it the data, in chunks of blocksize characters.
Retrieves remotefile in binary mode, storing the result in localfile. If localfile is nil, returns retrieved data. If a block is supplied, it is passed the retrieved data in blocksize chunks.
Transfers localfile to the server in binary mode, storing the result in remotefile. If a block is supplied, calls it, passing in the transmitted data in blocksize chunks.
Returns the last modification time of the (remote) file. If local is true, it is returned as a local time, otherwise it’s a UTC time.
Closes the connection. Further operations are impossible until you open a new connection with connect.
Returns true iff the connection is closed.
Creates a new Net::HTTP object, then additionally opens the TCP connection and HTTP session.
Arguments are the following:
hostname or IP address of the server
port of the server
address of proxy
port of proxy
user of proxy
pass of proxy
optional hash
opt sets following values by its accessor. The keys are ca_file, ca_path, cert, cert_store, ciphers, close_on_empty_response, key, open_timeout, read_timeout, ssl_timeout, ssl_version, use_ssl, verify_callback, verify_depth and verify_mode. If you set :use_ssl as true, you can use https and default value of verify_mode is set as OpenSSL::SSL::VERIFY_PEER.
If the optional block is given, the newly created Net::HTTP object is passed to it and closed when the block finishes. In this case, the return value of this method is the return value of the block. If no block is given, the return value of this method is the newly created Net::HTTP object itself, and the caller is responsible for closing it upon completion using the finish() method.
Returns true if the HTTP session has been started.
Opens a TCP connection and HTTP session.
When this method is called with a block, it passes the Net::HTTP object to the block, and closes the TCP connection and HTTP session after the block has been executed.
When called with a block, it returns the return value of the block; otherwise, it returns self.
Sends a PATCH request to the path and gets a response, as an HTTPResponse object.
