Hi,
Following are the release notes of the upcoming MacRuby 0.6 release. We will
prepare the installer package and write a more explanatory announcement on the
blog a bit later.
This closes a very successful 4 months development period since the last
release!
Laurent
Highlights:
* MacRuby is now stable for Cocoa development.
* Debugging support in both the compiler & the VM (experimental). Introduced
macrubyd as a command-line tool to pilot the debugger.
* New Hash class. Honors insertion ordering, optimized for Ruby immediate types.
* New String class. Supports the Ruby 1.9 encoding semantics and can also hold
binary data. Removed the old hidden ByteString class. Symbol has also been
rewritten to support multibyte characters.
* New Regexp class. Thread-safe, based on the ICU framework. Oniguruma is no
longer used.
* Additional, higher-level abstractions and convenience APIs for GCD, such as
the Job and Proxy classes, via the "dispatch" library.
* Support for C extensions written for MRI (experimental).
* Rewrote the Foundation built-in classes glue to conform better to the Ruby
semantics and be more robust in the future. A lot of unused code was then
deleted.
* About 85% of global RubySpecs pass rate.
Other Changes:
* Fixed a bug in #caller to remove itself from the backtrace.
* Make sure #at_exit blocks are called within exception handlers.
* yaml: implement YamlNode.
* Fixed a bug in File.open to handle given path argument as a path and not a
string.
* Fixed a constant lookup bug inside Foo::bar modules.
* Fixed a constant lookup bug inside #instance_eval.
* Fixed a deadlock when autoloading constants.
* Fixed a GC bug when passing thread-local objects to a new thread.
* RubyGems was updated to 1.3.6.
* Better signal handling support.
* Make sure Fixnum and Float boxes honor -copyWithZone:.
* Fixed a bug in #autoload from a mixed module.
* Register not implemented methods with rb_f_notimplement().
* Properly pop exceptions from the VM stack when we unwind from a handler.
* Added support for blocks symbolication.
* Make sure to catch Exception-based exceptions when requiring a file.
* Changed generic/native/class instance variables to use GC associative
references and keep the global hash for immediates.
* Introduce RubyObject, a hidden class used as the basic class of all
ruby-created classes.
* Fixed an infinite loop in Object#freeze that only occurs at SAFE level 4.
* #respond_to? now returns false in case the method is not implemented.
* GC.count is no longer implemented.
* Added support for the flip-flop operator.
* macruby_deploy: make sure .rbo files are properly linked when MacRuby is
embedded into an app.
* Added encoding-related exceptions.
* Fixed #flatten on NSArrays.
* Get rid of bad alloca() calls to avoid stack corruption.
* Disable frame pointer elimination optimization in the JIT.
* Simplified constant lookup primitives.
* Removed an old limitation of 32-bit MacRuby being unable to load .rbo files.
* Don't always assume that a thread has a group.
* Array#sample: raise an exception if given count is negative.
* When doing an assignment from thread X to thread Y's stack, defeat the
thread-local collector by making X leave the ownership of the object.
* BasicObject#initialize: do not forward -init in case it's a ruby method.
* Added support for methods defined for the MRI ABI (using rb_define_method &
friends).
* Class#clone and Module#clone: now copying methods and constants.
* Class#instance_methods and Module#instance_methods: do not include the
superclass methods.
* Rewrote the String formatting code to no longer be a stub of CFString.
* Removed the testrb and erb executables.
* Inspect message should always start by a #.
* Hash#compare_by_identity, #compare_by_identity?, #default_proc=: added.
* Hash#dup: fixed to honor subclasses.
* Hash#[]=: fixed to duplicate and freeze string keys.
* Fixed some freeze/taint problems with immediates.
* Kernel.Integer: upgraded to 1.9.
* yaml: Don't break :inline structures at 80 column boundaries.
* Integrate Mersenne Twister based random number generator from 1.9 upstream.
* Kernel#respond_to_missing?: added.
* Kernel#caller: now honor the skip argument.
* Hash#clone: keep singleton classes.
* Array#join: convert separator as string.
* Array#<=>: return nil if given obj is not array.
* Array#dup/#clone: appropriately handle singleton classes.
* When calling method missing, don't assume #method: takes only one argument.
* Allow methods/blocks with 12+ arguments.
* Delegate #copyWithZone to #dup, as we don't do anything with the zone yet.
* Copy the `trusted' state when creating a copy with #dup.
* Fixed a crasher in ossl_rand.
* A lot of fixes in String/Symbol/Regexp due to the ICU branch rewrite/merge.
* Fixed a buffer overflow when computing helper selectors in the dispatcher.
* Make sure #to_enum verifies that the argument is a symbol.
* Array#rindex: don't lookup argument in an empty array.
* Array#pack: fixed tainting of resulted string.
* Avoid a crash in #define_singleton_method on immediate types.
* Fixed a typo message in mkmf.rb.
* Avoid integer truncation in BigDecimal.
* Fixed a memory crasher in Bignum reallocation.
* When dispatching a custom #respond_to? method, do not pass the second
optional argument in case the arity is incompatible.
* Fix random generation of bignums on 64-bit 10.6+ machines.
* Fixed a bug in mkmf.rb (backported from upstream 1.9).
* It is now possible to pass Proc to native C/ObjC functions or methods
accepting function pointers.
* Make Symbol compliant to NSCoding.
* yaml: cleaned the extension code and fixed a few misc bugs.
* Set the maxgroups constant to NGROUPS_MAX.
* IO#tell, IO#seek: should not require readability and should be usable on
write-only or read-only IOs.
* Now AOT compiling rexml and xmlrpc standard libraries.
* When defining a class, only allow a class as the super class (and not
modules).
* Added notify_post.rb sample.
* Fixed bugs in ZSUPER (super with no argument and no parenthesis) compilation
inside blocks.
* Fixed a problem with Array#to_a.
* Fixed a bug in Module#initialize which could be re-entered upon +initialize.
* attr_accessor and attr_writer now generates writers that send KVO
notifications (if #framework was called at least once).
* Fixed a synchronization bug in the backquote operator.
* Rewrote the super dispatcher to not rely on the stack trace.
* Always try helper methods if a class is not a RubyObject descendant.
* Better Objective-C ignored selector detection.
* Implemented BEGIN{}.
* Use the same message format for printed exceptions everywhere.
* When preparing a method, do an extra resolve pass in case the Objective-C
cache is invalid.
* Force class initialization upon lazy lookup.
* Added support for Array arguments in IO.popen.
* Disable the lazy JIT in case the target class already has a custom
Objective-C method resolver (like CALayer).
* Do not auto-initialize classes that are not NSObject-based (like NSProxy).
* Added Pointer#cast! method to retype pointers.
* Allow any pointer to be converted to void*.
* Fix bugs in the way Objective-C method types were generated.
* When we acquire the core global lock, make sure we also release it in case an
exception happens.
* MacRuby will no longer insert the special primitive methods when you directly
subclass NSArray, NSString and NSDictionary. It is unlikely to happen anymore
with the new architecture.
* When re-typing methods, do not re-type the same method twice and make sure
the new signature matches the ruby arity.
* Fixed a bug in TypeArity() where stack size annotations were not ignored.
* The VM is now multithreaded-aware by default.
* When checking if a given BridgeSupport path has already been loaded, do a
case insensitive search.
* Added support for anonymous structures (like {?=qq}).
* Added several missing GC write barriers all around the code.
* Make NSString, NSArray and NSDictionary yamlable.
* Rewrote class flags to not use the version field anymore, better typing
system, fixed misc bugs.
* IRB should not crash when receiving Obj-C exceptions.
* Added simple compiler support for bit fields and C-style arrays.
* Improved support of opaque structures.
* Fixed the ViewModelDemo sample syntax.
