Return internal class of obj.
obj can be an instance of InternalObjectWrapper
.
Note that you should not use this method in your application.
Calls CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON). Starts tracking memory allocations. See also OpenSSL.print_mem_leaks
.
This is available only when built with a capable OpenSSL
and –enable-debug configure option.
Set
terminal size to rows
and columns
.
See GNU Readline’s rl_set_screen_size function.
Raises NotImplementedError
if the using readline library does not support.
Specifies VI editing mode. See the manual of GNU Readline
for details of VI editing mode.
Raises NotImplementedError
if the using readline library does not support.
Returns true if vi mode is active. Returns false if not.
Raises NotImplementedError
if the using readline library does not support.
Specifies Emacs editing mode. The default is this mode. See the manual of GNU Readline
for details of Emacs editing mode.
Raises NotImplementedError
if the using readline library does not support.
Returns true if emacs mode is active. Returns false if not.
Raises NotImplementedError
if the using readline library does not support.
Specifies a Proc
object proc
to call after the first prompt has been printed and just before readline starts reading input characters.
See GNU Readline’s rl_pre_input_hook variable.
Raises ArgumentError
if proc
does not respond to the call method.
Raises NotImplementedError
if the using readline library does not support.
Returns a Proc
object proc
to call after the first prompt has been printed and just before readline starts reading input characters. The default is nil.
Raises NotImplementedError
if the using readline library does not support.
Set
the default id conversion object.
This is expected to be an instance such as DRb::DRbIdConv
that responds to to_id
and to_obj
that can convert objects to and from DRb
references.
See DRbServer#default_id_conv.

This method removes a file system entry path
. path
shall be a regular file, a directory, or something. If path
is a directory, remove it recursively. This method is required to avoid TOCTTOU (time-of-check-to-time-of-use) local security vulnerability of rm_r
. rm_r
causes security hole when:
Parent directory is world writable (including /tmp).
Removing directory tree includes world writable directory.
The system has symbolic link.
To avoid this security hole, this method applies special preprocess. If path
is a directory, this method chown(2) and chmod(2) all removing directories. This requires the current process is the owner of the removing whole directory tree, or is the super user (root).
WARNING: You must ensure that ALL parent directories cannot be moved by other untrusted users. For example, parent directories should not be owned by untrusted users, and should not be world writable except when the sticky bit set.
WARNING: Only the owner of the removing directory tree, or Unix super user (root) should invoke this method. Otherwise this method does not work.
For details of this security vulnerability, see Perl’s case:
For fileutils.rb, this vulnerability is reported in [ruby-dev:26100].

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

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.
Register a Gem::Specification
for default gem.
Two formats for the specification are supported:
MRI 2.0 style, where spec.files contains unprefixed require names. The spec’s filenames will be registered as-is.
New style, where spec.files contains files prefixed with paths from spec.require_paths. The prefixes are stripped before registering the spec’s filenames. Unprefixed files are omitted.
Clear default gem related variables. It is for test
Paths where RubyGems’ .rb files and bin files are installed

Hangul Algorithm
Encodes this DH
to its DER encoding. Note that any existing per-session public/private keys will not get encoded, just the Diffie-Hellman parameters will be encoded.
Generates a private and public key unless a private key already exists. If this DH
instance was generated from public DH
parameters (e.g. by encoding the result of DH#public_key
), then this method needs to be called first in order to generate the per-session keys before performing the actual key exchange.
dh = OpenSSL::PKey::DH.new(2048) public_key = dh.public_key #contains no private/public key yet public_key.generate_key! puts public_key.private? # => true
Sets p
, q
, g
for the DH
instance.
