Convenience method for Shell::CommandProcessor.undef_system_command

Returns the status of the global “report on exception” condition.

The default is true since Ruby 2.5.

All threads created when this flag is true will report a message on $stderr if an exception kills the thread.

Thread.new { 1.times { raise } }

will produce this output on $stderr:

#<Thread:...> terminated with exception (report_on_exception is true):
Traceback (most recent call last):
        2: from -e:1:in `block in <main>'
        1: from -e:1:in `times'

This is done to catch errors in threads early. In some cases, you might not want this output. There are multiple ways to avoid the extra output:

• If the exception is not intended, the best is to fix the cause of the exception so it does not happen anymore.

• If the exception is intended, it might be better to rescue it closer to where it is raised rather then let it kill the Thread.

• If it is guaranteed the Thread will be joined with Thread#join or Thread#value, then it is safe to disable this report with Thread.current.report_on_exception = false when starting the Thread. However, this might handle the exception much later, or not at all if the Thread is never joined due to the parent thread being blocked, etc.

There is also an instance level method to set this for a specific thread, see report_on_exception=.

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 version of the latest release-version of gem name

Return a String indicating who caused this request to be added (only valid for implicit requests)

Execute the provided block, but preserve the exception mode

BigDecimal.save_exception_mode do
  BigDecimal.mode(BigDecimal::EXCEPTION_OVERFLOW, false)
  BigDecimal.mode(BigDecimal::EXCEPTION_NaN, false)

  BigDecimal(BigDecimal('Infinity'))
  BigDecimal(BigDecimal('-Infinity'))
  BigDecimal(BigDecimal('NaN'))
end

For use with the BigDecimal::EXCEPTION_*

See BigDecimal.mode

Returns reference counter of Dispatch interface of WIN32OLE object. You should not use this method because this method exists only for debugging WIN32OLE.

Breaks the buffer into lines that are shorter than maxwidth

Counts objects for each T_IMEMO type.

This method is only for MRI developers interested in performance and memory usage of Ruby programs.

It returns a hash as:

{:imemo_ifunc=>8,
 :imemo_svar=>7,
 :imemo_cref=>509,
 :imemo_memo=>1,
 :imemo_throw_data=>1}

If the optional argument, result_hash, is given, it is overwritten and returned. This is intended to avoid probe effect.

The contents of the returned hash is implementation specific and may change in the future.

In this version, keys are symbol objects.

This method is only expected to work with C Ruby.

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.

Makes a list of existing constants public.

Makes a list of existing constants private.

Is this handler a streaming handler?

Set the version to version, potentially also setting required_rubygems_version if version indicates it is a prerelease.

Turns on net/http 1.2 (Ruby 1.8) features. Defaults to ON in Ruby 1.8 or later.

Sends an HTTPRequest object req to the HTTP server.

If req is a Net::HTTP::Post or Net::HTTP::Put request containing data, the data is also sent. Providing data for a Net::HTTP::Head or Net::HTTP::Get request results in an ArgumentError.

Returns an HTTPResponse object.

When called with a block, passes an HTTPResponse object to the block. The body of the response will not have been read yet; the block can process it using HTTPResponse#read_body, if desired.

This method never raises Net::* exceptions.

Returns system information.

Sends a STORE command to alter data associated with messages in the mailbox, in particular their flags. The set parameter is a number, an array of numbers, or a Range object. Each number is a message sequence number. attr is the name of a data item to store: ‘FLAGS’ will replace the message’s flag list with the provided one, ‘+FLAGS’ will add the provided flags, and ‘-FLAGS’ will remove them. flags is a list of flags.

The return value is an array of Net::IMAP::FetchData. For example:

p imap.store(6..8, "+FLAGS", [:Deleted])
#=> [#<Net::IMAP::FetchData seqno=6, attr={"FLAGS"=>[:Seen, :Deleted]}>, \\
     #<Net::IMAP::FetchData seqno=7, attr={"FLAGS"=>[:Seen, :Deleted]}>, \\
     #<Net::IMAP::FetchData seqno=8, attr={"FLAGS"=>[:Seen, :Deleted]}>]

Returns error reason. Override this for I18N.

This method retrieves the system identifier identifying the document’s DTD
