Public Class Methods
create_listeners(address, port)
Creates TCP server sockets bound to address
:port
and returns them.
It will create IPV4 and IPV6 sockets on all interfaces.
# File webrick/utils.rb, line 61 def create_listeners(address, port) unless port raise ArgumentError, "must specify port" end sockets = Socket.tcp_server_sockets(address, port) sockets = sockets.map {|s| s.autoclose = false ts = TCPServer.for_fd(s.fileno) s.close ts } return sockets end
create_self_signed_cert(bits, cn, comment)
Creates a self-signed certificate with the given number of
bits
, the issuer cn
and a comment
to
be stored in the certificate.
# File webrick/ssl.rb, line 92 def create_self_signed_cert(bits, cn, comment) rsa = OpenSSL::PKey::RSA.new(bits){|p, n| case p when 0; $stderr.putc "." # BN_generate_prime when 1; $stderr.putc "+" # BN_generate_prime when 2; $stderr.putc "*" # searching good prime, # n = #of try, # but also data from BN_generate_prime when 3; $stderr.putc "\n" # found good prime, n==0 - p, n==1 - q, # but also data from BN_generate_prime else; $stderr.putc "*" # BN_generate_prime end } cert = OpenSSL::X509::Certificate.new cert.version = 2 cert.serial = 1 name = OpenSSL::X509::Name.new(cn) cert.subject = name cert.issuer = name cert.not_before = Time.now cert.not_after = Time.now + (365*24*60*60) cert.public_key = rsa.public_key ef = OpenSSL::X509::ExtensionFactory.new(nil,cert) ef.issuer_certificate = cert cert.extensions = [ ef.create_extension("basicConstraints","CA:FALSE"), ef.create_extension("keyUsage", "keyEncipherment"), ef.create_extension("subjectKeyIdentifier", "hash"), ef.create_extension("extendedKeyUsage", "serverAuth"), ef.create_extension("nsComment", comment), ] aki = ef.create_extension("authorityKeyIdentifier", "keyid:always,issuer:always") cert.add_extension(aki) cert.sign(rsa, OpenSSL::Digest::SHA1.new) return [ cert, rsa ] end
getservername()
The server hostname
# File webrick/utils.rb, line 47 def getservername host = Socket::gethostname begin Socket::gethostbyname(host)[0] rescue host end end
random_string(len)
Generates a random string of length len
# File webrick/utils.rb, line 84 def random_string(len) rand_max = RAND_CHARS.bytesize ret = "" len.times{ ret << RAND_CHARS[rand(rand_max)] } ret end
set_close_on_exec(io)
Sets the close on exec flag for io
# File webrick/utils.rb, line 27 def set_close_on_exec(io) io.close_on_exec = true if io.respond_to?(:close_on_exec=) end
set_non_blocking(io)
Sets IO operations on io
to be non-blocking
# File webrick/utils.rb, line 20 def set_non_blocking(io) io.nonblock = true if io.respond_to?(:nonblock=) end
su(user)
Changes the process’s uid and gid to the ones of user
# File webrick/utils.rb, line 34 def su(user) if pw = Etc.getpwnam(user) Process::initgroups(user, pw.gid) Process::Sys::setgid(pw.gid) Process::Sys::setuid(pw.uid) else warn("WEBrick::Utils::su doesn't work on this platform") end end
timeout(seconds, exception=Timeout::Error)
Executes the passed block and raises exception
if execution
takes more than seconds
.
If seconds
is zero or nil, simply executes the block
# File webrick/utils.rb, line 234 def timeout(seconds, exception=Timeout::Error) return yield if seconds.nil? or seconds.zero? # raise ThreadError, "timeout within critical session" if Thread.critical id = TimeoutHandler.register(seconds, exception) begin yield(seconds) ensure TimeoutHandler.cancel(id) end end
