Returns the status of the thread-local “report on exception” condition for this thr.
The default value when creating a Thread is the value of the global flag Thread.report_on_exception.
See also report_on_exception=.
There is also a class level method to set this for all new threads, see ::report_on_exception=.
When set to true, a message is printed on $stderr if an exception kills this thr. See ::report_on_exception for details.
See also report_on_exception.
There is also a class level method to set this for all new threads, see ::report_on_exception=.
Returns the last win32 Error of the current executing Thread or nil if none
Sets the last win32 Error of the current executing Thread to error
Verify compaction reference consistency.
This method is implementation specific. During compaction, objects that were moved are replaced with T_MOVED objects. No object should have a reference to a T_MOVED object after compaction.
This function doubles the heap to ensure room to move all objects, compacts the heap to make sure everything moves, updates all references, then performs a full GC. If any object contains a reference to a T_MOVED object, that object should be pushed on the mark stack, and will make a SEGV.
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
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 the name of the method defined.
Returns the latest release-version specification for the gem name.
Returns the version of the latest release-version of gem name
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.
Is this tar entry a directory?
Like Enumerable#slice_before, but chains operation to be lazy-evaluated.
ptr.to_str => string ptr.to_str(len) => string
Returns the pointer contents as a string.
When called with no arguments, this method will return the contents with the length of this pointer’s size.
When called with len, a string of len bytes will be returned.
