Verify internal consistency.
This method is implementation specific. Now this method checks generational consistency if RGenGC is supported.
Returns the size of memory allocated by malloc().
Only available if ruby was built with CALC_EXACT_MALLOC_SIZE.
Shortcut for defining multiple delegator methods, but with no provision for using a different name. The following two code samples have the same effect:
def_delegators :@records, :size, :<<, :map def_delegator :@records, :size def_delegator :@records, :<< def_delegator :@records, :map
Define method as delegator instance method with an optional alias name ali. Method calls to ali will be delegated to accessor.method.
class MyQueue extend Forwardable attr_reader :queue def initialize @queue = [] end def_delegator :@queue, :push, :mypush end q = MyQueue.new q.mypush 42 q.queue #=> [42] q.push 23 #=> NoMethodError
Shortcut for defining multiple delegator methods, but with no provision for using a different name. The following two code samples have the same effect:
def_delegators :@records, :size, :<<, :map def_delegator :@records, :size def_delegator :@records, :<< def_delegator :@records, :map
Defines a method method which delegates to accessor (i.e. it calls the method of the same name in accessor). If new_name is provided, it is used as the name for the delegate method.
Returns whether or not the struct of type type contains member. If it does not, or the struct type can’t be found, then false is returned. You may optionally specify additional headers in which to look for the struct (in addition to the common header files).
If found, a macro is passed as a preprocessor constant to the compiler using the type name and the member name, in uppercase, prepended with HAVE_.
For example, if have_struct_member('struct foo', 'bar') returned true, then the HAVE_STRUCT_FOO_BAR preprocessor macro would be passed to the compiler.
HAVE_ST_BAR is also defined for backward compatibility.
Returns a list of paths matching glob from the latest gems that can be used by a gem to pick up features from other gems. For example:
Gem.find_latest_files('rdoc/discover').each do |path| load path end
if check_load_path is true (the default), then find_latest_files also searches $LOAD_PATH for files as well as gems.
Unlike find_files, find_latest_files will return only files from the latest version of a gem.
The file name and line number of the caller of the caller of this method.
depth is how many layers up the call stack it should go.
e.g.,
def a; Gem.location_of_caller; end a #=> [“x.rb”, 2] # (it’ll vary depending on file name and line number)
def b; c; end def c; Gem.location_of_caller(2); end b #=> [“x.rb”, 6] # (it’ll vary depending on file name and line number)
Returns the latest release-version specification for the gem name.
Returns the latest release version of RubyGems.
Returns the version of the latest release-version of gem name
Deduce Ruby’s –program-prefix and –program-suffix from its install name
Adds a certificate to the context. pkey must be a corresponding private key with certificate.
Multiple certificates with different public key type can be added by repeated calls of this method, and OpenSSL will choose the most appropriate certificate during the handshake.
cert=, key=, and extra_chain_cert= are old accessor methods for setting certificate and internally call this method.
A certificate. An instance of OpenSSL::X509::Certificate.
The private key for certificate. An instance of OpenSSL::PKey::PKey.
Optional. An array of OpenSSL::X509::Certificate. When sending a certificate chain, the certificates specified by this are sent following certificate, in the order in the array.
rsa_cert = OpenSSL::X509::Certificate.new(...) rsa_pkey = OpenSSL::PKey.read(...) ca_intermediate_cert = OpenSSL::X509::Certificate.new(...) ctx.add_certificate(rsa_cert, rsa_pkey, [ca_intermediate_cert]) ecdsa_cert = ... ecdsa_pkey = ... another_ca_cert = ... ctx.add_certificate(ecdsa_cert, ecdsa_pkey, [another_ca_cert])
OpenSSL before the version 1.0.2 could handle only one extra chain across all key types. Calling this method discards the chain set previously.
Creates a new X509::Extension with passed values. See also x509v3_config(5).
