Sets IO operations on io to be non-blocking
@return [String] a string suitable for debugging
Is there a path from ‘other` to `self` following edges in the dependency graph? @return true iff there is a path following edges within this {#graph}
@return [RequirementState] the current state the resolution is
operating upon
If stat is readable by others, returns an integer representing the file permission bits of stat. Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat(2).
m = File.stat("/etc/passwd").world_readable? #=> 420 sprintf("%o", m) #=> "644"
Returns true if stat is writable by the real user id of this process.
File.stat("testfile").writable_real? #=> true
Same as executable?, but tests using the real owner of the process.
Returns a DRb::DRbSSLSocket instance as a server-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 the eigenvector matrix V
