Returns the new state. When set to true, all threads created afterwards will inherit the condition and report a message on $stderr if an exception kills a thread:
Thread.report_on_exception = true t1 = Thread.new do puts "In new thread" raise "Exception from thread" end sleep(1) puts "In the main thread"
This will produce:
In new thread #<Thread:...prog.rb:2> terminated with exception (report_on_exception is true): Traceback (most recent call last): prog.rb:4:in `block in <main>': Exception from thread (RuntimeError) In the main thread
See also ::report_on_exception.
There is also an instance level method to set this for a specific thread, see report_on_exception=.
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 expands 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.
Enable to measure GC time. You can get the result with GC.stat(:time). Note that GC time measurement can cause some performance overhead.
Return measure_total_time flag (default: true). Note that measurement can affect the application performance.
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.
Securely removes the entry given by path, which should be the entry for a regular file, a symbolic link, or a directory.
Argument path should be interpretable as a path.
Avoids a local vulnerability that can exist in certain circumstances; see Avoiding the TOCTTOU Vulnerability.
Optional argument force specifies whether to ignore raised exceptions of StandardError and its descendants.

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.
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.
