Release 3.91

Version 3.91 (2018-01-15)

• WIP: Fix range of Fixnum. Closes #3636. (Brian Shirai)

• Introduce proper lock for internalizing CompiledCode. (Brian Shirai)

• Cleanup old C++ missing classes. (Brian Shirai)

• Remove missing/hashtable for Leopard. (Brian Shirai)

• Accommodate registers. (Brian Shirai)
  This is a temporary approach until the CallFrame is re-worked to treat
  registers as first-class entities.

• Add more instruction templates. (Brian Shirai)

• Unmarshal CompiledCode#registers. (Brian Shirai)

• Remove VM unmarshal tests. (Brian Shirai)
  This facility is so fundamental that there's no way for Rubinius to
  function if it isn't working, so the test for it adds no information and
  duplicates work.

• Add implementation for more new instructions. (Brian Shirai)

• Update compiler version. (Brian Shirai)

• More instructions and specs. (Brian Shirai)

• Use unmanaged memory for CallSite. (Brian Shirai)
  This is a provisional implementation awaiting full support for reference
  counting in the managed heap and garbage collector.

There are broadly four kinds of memory in Rubinius:

1. Memory on the call stack (ie not C locals) like the CallFrame object;
2. Unmanaged memory that is part of C/C++ structures (eg an instance of
   std::string) and really not closely related to managed (eg Ruby)
   objects;
3. Unmanaged memory that is closely related (eg MachineCode, CallSite)
   to managed (eg Ruby) objects;
4. Managed (eg Ruby) objects.

It's possible to put both 3 and 4 into the same category (ie managed
objects) if we allow for every one of those objects to use an extra
machine word or two (or some sort of side table) in order to keep track
of them.

The challenge in this approach is to ensure that the garbage collector
knows how to process them to find all the references they may contain.

By creating a composite model for the garbage collector that uses both
tracing and reference counting, it's possible to put managed objects in
places that won't be traced, and preserve their lifetime by counting how
many times they are referenced by live objects.

Another thing to note about 3 and 4 is that the difference mostly comes
down to whether the object will be exposed as a reference to the managed
(eg Ruby) code. For example, can it be stored in a local variable, or in
an Array or Hash? If it can be stored, then it needs to respond like a
managed object (eg what happens when it's passed to the method 'p').

This new mechanism maintains CallSite as a Ruby object because it's
useful for conveying the information at the call site to Ruby code. In
the future, arbitrary objects will be able to interact by means of
functions attached to them via FFI, so the system can handle non-managed
objects in a manner that is consistent with how it handles managed
objects.

Release 3.90

Version 3.90 (2018-01-06)

• Reset ThreadNexus mutex after fork(). (Brian Shirai)
• Add start of PEG instructions. (Brian Shirai)

• Update gems_list.txt. (Brian Shirai)
• Start adding instrumentation instructions. (Brian Shirai)
• update minitest, fixes and closes GH-3760 (Chuck Remes)
• minitest is a special case for gem updates, so update scripts that refer to it (Chuck Remes)
• update rake, rb-readline, and rdoc to latest versions (Chuck Remes)
• fallback to rdoc 5.1.0 last version that does NOT require ripper (Chuck Remes)
• only print log message if (Chuck Remes)
• Implement m_counter insn. (Brian Shirai)
• Better Thread#kill spec. (Brian Shirai)
• Update some diagnostics. (Brian Shirai)
• verify that each with a limit returns no more than limit chars (Chuck Remes)
• fix each(limit) - longer explanation below (Chuck Remes)
  When calling each(limit) or each_line(limit) there is a lot of
  logic to figure out if a separator or limit were passed. In
  the case of #each, when a limit is specified it still picks up
  $/ as the separator. Therefore EachReader#read_to_separator_with_limit
  is used. There was a bug where a buffer was being assigned another
  string fragment buffer += result which returned a new buffer
  object. The calling method was relying on buffer being the same
  object reference passed to its child method. Changing to #<<
  resolved the bug.

Separately, the spec to test this behavior showed that #each_line
broke. It has similar logic to figure out separator or limit but
in this case it was passing each(5, 5, &blk) after figuring out
the limit. The fix is to reset sep_or_limit once we know what
it is supposed to be.

Incidently the only way to call EachReader#read_to_limit is to
set $/ = nil and send no separator in the #each method call.

• Fixed inline cache for recursive calls. (Brian Shirai)
  We cache a method at a call site after the method has been invoked so
  that we don't cache methods that raised exceptions.

But when a method is called recursively, the state of the cache will
have changed and when unwinding from the dispatch call, we need check
that the state of the cache is what we assume it to be. A similar thing
can happen when code is executing concurrently.
