Outputs the results from the profiler.
See Profiler__ for more information.
Try to activate a gem containing path. Returns true if activation succeeded or wasn’t needed because it was already activated. Returns false if it can’t find the path in a gem.
Adds a post-build hook that will be passed an Gem::Installer instance when Gem::Installer#install is called. The hook is called after the gem has been extracted and extensions have been built but before the executables or gemspec has been written. If the hook returns false then the gem’s files will be removed and the install will be aborted.
Adds a post-installs hook that will be passed a Gem::DependencyInstaller and a list of installed specifications when Gem::DependencyInstaller#install is complete
Adds a hook that will get run after Gem::Specification.reset is run.
Adds a pre-install hook that will be passed an Gem::Installer instance when Gem::Installer#install is called. If the hook returns false then the install will be aborted.
Adds a pre-uninstall hook that will be passed an Gem::Uninstaller instance and the spec that will be uninstalled when Gem::Uninstaller#uninstall is called
Safely write a file in binary mode on all platforms.
Returns the time resolution returned by POSIX clock_getres() function.
clock_id specifies a kind of clock. See the document of Process.clock_gettime for details.
clock_id can be a symbol as Process.clock_gettime. However the result may not be accurate. For example, +Process.clock_getres(:GETTIMEOFDAY_BASED_CLOCK_REALTIME)+ returns 1.0e-06 which means 1 microsecond, but actual resolution can be more coarse.
If the given clock_id is not supported, Errno::EINVAL is raised.
unit specifies a type of the return value. Process.clock_getres accepts unit as Process.clock_gettime. The default value, :float_second, is also same as Process.clock_gettime.
Process.clock_getres also accepts :hertz as unit. :hertz means a the reciprocal of :float_second.
:hertz can be used to obtain the exact value of the clock ticks per second for times() function and CLOCKS_PER_SEC for clock() function.
+Process.clock_getres(:TIMES_BASED_CLOCK_PROCESS_CPUTIME_ID, :hertz)+ returns the clock ticks per second.
+Process.clock_getres(:CLOCK_BASED_CLOCK_PROCESS_CPUTIME_ID, :hertz)+ returns CLOCKS_PER_SEC.
p Process.clock_getres(Process::CLOCK_MONOTONIC) #=> 1.0e-09
Indicates whether this DH instance has a private key associated with it or not. The private key may be retrieved with DH#priv_key.
The list of cipher suites configured for this context.
Sets the list of available cipher suites for this context. Note in a server context some ciphers require the appropriate certificates. For example, an RSA cipher suite can only be chosen when an RSA certificate is available.
Writes string to the SSL connection.
Sends “close notify” to the peer and tries to shut down the SSL connection gracefully.
The cipher being used for the current connection
A description of the current connection state. This is for diagnostic purposes only.
Sets the server hostname used for SNI. This needs to be set before SSLSocket#connect.
See TCPServer#listen for details.
