Here are the release notes for MacRuby 0.9! An e-mail announcing the release
will be following.
Highlights:
- Lots of stability fixes (crashers, memory leaks and race conditions), and a
few performance improvements.
- The internal representation of Strings changed from a dual binary / UTF-16
model to a pure binary one, principally to avoid problems in multithreaded
applications. Performance should remain the same in most cases.
- The macruby_deploy program has been enhanced to embed RubyGems (with
dependencies) and BridgeSupport files. See the new respective --gem and --bs
options.
- The libmacruby-static.a library is not built by default anymore, because
static compilation is still a work in progress.
- Upgraded to RubyGems 1.4.2.
Changes:
- Fix a bug in IO.open() where numeric file descriptors could not be passed as
the first argument.
- Fix an assertion that could happen when calling #methods & friends on a class
that contains a method name larger than 100 characters.
- Fix a bug in IO.open() where the given path would not be handled as a path
(calling #to_path if necessary).
- Fix a bug in the YAML extension where yajl_free() would be called on a NULL
pointer.
- Fix a bug in the OpenSSL extension, when calling ossl_pkey_sign().
- Fix a bug where calling a method defined with #define_method with a block
accepting a splat argument (arity -2) would crash.
- Fix Ruby warnings in the YAML extension.
- Fix a bug when some splat methods defined with #define_method() would
segfault at dispatch time.
- Improve the internal rb_eql() routine for performance, makes faster hash
lookup / keys comparison operations.
- Improve the hashing function for Arrays.
- Move the conformsToProtocol: and performSelector: default logic on direct
pure-Ruby subclasses.
- Fix a bug in IO#close_write where IOError would not be thrown if the stream
was readable and non-duplex.
- Fix a bug in IO#write where an exception would be raised if the stream was
read-only when writing 0 bytes of data.
- Fix a bug in Kernel.require where a file path starting with '~' would not be
loaded.
- Fix a bug in String#gsub! where we would segfault during string concatenation.
- Fix a bug in the compilation of scopes where the current_block_arg state
variable wouldn't be re-entrant (this fixes the compilation of the mechanize
library).
- Fix bugs in String#inspect when called on a string that contains invalid and
non-BMP characters.
- Fix a potential memory crasher in String#sub and String#gsub where free'd
memory would be reused.
- Fix a bug where $FILENAME, $* and $-W could be changed.
- Fix a bunch of bugs in Array methods where SecurityError would not be raised
when $SAFE is 4.
- Fix a bug in Kernel#untrust where an exception would not be raised on a
frozen object.
- Fix a bug in Kernel#trust where an exception would not be raised on a frozen
object.
- Fix a bug in Kernel#trust where an exception would not be raised if $SAFE is
equal or greater than 3.
- Fix a crash in Rational#rationalize due to registering the method with a
wrong arity.
- Fix a bug when we would free outer memory but still keep outers pointing to
that memory location, causing crashes later during const lookup (this fixes
rspec).
- Fix a bug in Struct#hash when called on recursive structs.
- Fix a bug in Array#== when called with recursive arrays.
- Fix a bug in StringIO#puts when called with recursive arrays.
- Fix a bug in Exception#== when an infinite loop would be entered when
comparing exceptions from different classes.
- Fix a bug when #initialize_copy would not raise an exception when called on
Object or BasicObject.
- Add support for encodings ISO8859_{2..16}.
- Fix a bug in String#search_codepoint where breaks were ignored.
- Fix a bug in OpenSSL::BN#to_s.
- Fix a bug in OpenSSL::PKey::DH#compute_key.
- Fix a bug in OpenSSL::X509::Attribute#to_der.
- Fix a bug in OpenSSL::PKCS5.pbkdf2_hmac(_sha1).
- Fix a bug in OpenSSL::PKey::DSA#syssign.
- Fix a bug in OpenSSL's ossl_x509store_initialize() function where an internal
value would not properly be initialized.
- Fix a bunch of bugs in Array methods where an exception would not be raised
when passing very large indexes or ranges.
- Fix a bug in Array#inspect where an untrusted string would not be returned.
- Fix a bug in String#unpack when called with a block.
- Add support for variadic objc method dispatch in the parser.
- Fix a bug in Socket.pair where the sockets would not be yielded when passing
a block.
- Fix a bug in Socket.pair(domain, type, protocol) and Socket.new(domain, type,
protocol) where protocol would not be an optional argument.
- Fix a bug in Socket.getservbyport(port) where a port outside the uint16 range
would be accepted.
- Fix a bug in Socket.getservbyport where the network byte order value would
not be passed to the underlying API.
- Fix a memory leak and potential crasher in Regexp's internal
rb_reg_matcher_new() function.
- Fix various memory leaks and potential crashers in code paths that require
binary -> UTF-16 conversions.
- Fix a bug in OpenSSL::BN#prime?.
- Add the #size class method on BridgeSupport struct classes. Example,
NSRect#size returns the same as sizeof(NSRect) in C.
- Fix a bug in OpenSSL::SSL::SSLSocket#cert.
- Fix -[MacRuby evaluateFileAtPath:] to behave like #require, so that it can
also handle .rbo or .bundle files.
- Fix a bug when sending KVO notifications on immediate objects would cause a
crash.
- Cleaned out all public header files.
- Fix a bug in Sandbox.new where passing a non-String object would cause a
crash.
- Add rb_str_plus() CRuby API.
- Fix a bug in {Thread,ThreadGroup,Mutex}#alloc where we would not return
objects from the current class (could be a subclass).
- Fix a bug in Kernel#public_method where an exception would not be raised when
called without public methods.
- Fix bugs in Module#{remove_method,undef_method,public} to honor untrusted
state.
- Add Pointer.magic_cookie to create pointers with arbitrary values (must fit
in a long). Example: Pointer.magic_cookie(42).
- Fix a bug in Module#method_defined? where false would not be returned was
passed the name of private method.
- Fix the compilation of C blocks to not use a global variable to store/load
the Proc object to call, but instead retrieve a reference to it from the block
literal argument. This fixes nested C blocks.
- Fix a bug in Kernel#<=> will 0 would not be returned when receiver's ==
return true.
- Fix a bug in Module#public_method_defined? where true would not be returned
when was passed name/symbol of public method.
- Fix a bug in Array#pack with format "fFeEdDgG" to raise a TypeError when does
not convert into float.
- Fix bugs in #sprintf when passing the following formats: "%# x", "%010.4f",
"%010.4u".
- Fix a bug in String#unpack with format 'Q' to add add nil for each element
requested beyond the end of the String.
- Fix a bug in String#scan to return an Array object with each element tainted
or untrusted when #scan returns nested arrays.
- Fix a bug in Array#[]= to check frozen state before attempting to coerce
arguments.
- Fix a bug in String#initialize to raise a RuntimeError if self is frozen.
- Fix a bunch of bugs detected by clang's link time optimization (LTO).
- Fix a bug in -[NSArray ==:] and -[NSDictionary ==:] where a crash would occur
if passed a Ruby immediate type.
- Fix bugs in String#each_char and String#ord to now raise an exception if the
String contain invalid characters.
- Fix a bug in String#ord to return the byte value even if a it's not an ASCII
character.
- Fix a bug in the dispatcher where free'd memory would be accessed.
- Fix a bug in #at_exit when the process would abort if a block raised an
exception.
- Fix a bug in Array#delete where we would check if the receiver can be
modified *after* modifying it.
- Fix a bug in Mutex and ThreadGroup where modifying internal array structures
under SAFE level of 4 would raise an exception.
- Fix a problem in #load: instead of crashing if we cannot locate the entry
point of a .rbo file, raise an exception with a message explaining the most
common problem cause instead.
- Fix a bug in the compilation of the 'next' expression which would not honor
ensure blocks.
- Add support for #define_method when passing Method.
- Fix a bug in StringScanner on multiline strings.
- Fix a bug in macirb where a syntax error would exit the program.
- Improve the performance of #pack with most flags by pre-allocating the result
bytestring, to avoid too-much frequent memory reallocations.
- Fix a 32-bit precision bug when converting Time objects to NSDate objects.
- Allow Float objects to be trusted/untrusted and tainted/untainted.
- Fix the default value of BasicSocket.do_not_reverse_lookup to be true.
