= NEWS for Ruby 1.9.3
|
|
|
|
This document is a list of user visible feature changes made between
|
|
releases except for bug fixes.
|
|
|
|
Note that each entry is kept so brief that no reason behind or
|
|
reference information is supplied with. For a full list of changes
|
|
with all sufficient information, see the ChangeLog file.
|
|
|
|
== Changes since the 1.9.2 release
|
|
=== License
|
|
|
|
* Ruby's License is changed from a dual license with GPLv2
|
|
to a dual license with 2-clause BSDL.
|
|
|
|
=== Known platform dependent issues
|
|
==== OS X Lion
|
|
|
|
* You have to configure ruby with '--with-gcc=gcc-4.2' if you're using
|
|
Xcode 4.1, or, if you're using Xcode 4.2, you have to configure ruby
|
|
with '--with-gcc=clang'.
|
|
|
|
=== C API updates
|
|
|
|
* rb_scan_args() is enhanced with support for option hash argument
|
|
extraction.
|
|
|
|
* ruby_vm_at_exit() added. This enables extension libs to hook a VM
|
|
termination.
|
|
|
|
* rb_reserved_fd_p() added. If you want to close all file descriptors,
|
|
check using this API. [ruby-core:37759]
|
|
|
|
=== Library updates (outstanding ones only)
|
|
|
|
* builtin classes
|
|
|
|
* ARGF
|
|
* new methods:
|
|
* ARGF.print
|
|
* ARGF.printf
|
|
* ARGF.putc
|
|
* ARGF.puts
|
|
* ARGF.read_nonblock
|
|
* ARGF.to_write_io
|
|
* ARGF.write
|
|
|
|
* Array
|
|
* extended method:
|
|
* Array#pack supports endian modifiers
|
|
|
|
* Bignum
|
|
* Multiplication algorithm for Bignums with a large number of digits over
|
|
150 BDIGITs is changed in order to reduce its calculation time.
|
|
Now such large Bignums are multiplied by using Toom-3 algorithm.
|
|
|
|
* Encoding
|
|
* new encodings:
|
|
* CP950
|
|
* CP951
|
|
* UTF-16
|
|
* UTF-32
|
|
* change alias:
|
|
* SJIS is Windows-31J
|
|
|
|
* File
|
|
* new constant:
|
|
* File::NULL
|
|
name of NULL device.
|
|
* File::DIRECT
|
|
name of O_DIRECT.
|
|
|
|
* IO
|
|
* extended method:
|
|
* IO#putc supports multibyte characters
|
|
* new methods:
|
|
* IO#advise
|
|
* IO.write(name, string, [offset] )
|
|
Write `string` to file `name`.
|
|
Opposite with File.read.
|
|
* IO.binwrite(name, string, [offset] )
|
|
binary version of IO.write.
|
|
|
|
* Kernel
|
|
* move #__id__ to BasicObject.
|
|
* extended method:
|
|
* Kernel#rand supports range argument
|
|
|
|
* Module
|
|
* new methods:
|
|
* Module#private_constant
|
|
* Module#public_constant
|
|
|
|
* Random
|
|
* extended method:
|
|
* Random.rand supports range argument
|
|
|
|
* String
|
|
* extended method:
|
|
* String#unpack supports endian modifiers
|
|
* new method:
|
|
* String#prepend
|
|
* String#byteslice
|
|
|
|
* Time
|
|
* extended method:
|
|
* Time#strftime supports %:z and %::z.
|
|
|
|
* Process
|
|
* Process#maxgroups and Process#maxgroups= now raise NotImplementedError if
|
|
the platform don't support supplementary groups concept.
|
|
|
|
* bigdecimal
|
|
|
|
* BigDecimal#power and BigDecimal#** support non-integral exponent.
|
|
|
|
* Kernel.BigDecimal and BigDecimal.new now accept instances of Integer,
|
|
Rational, Float, and BigDecimal. If you pass a Rational or a Float to
|
|
them, you must specify the precision to produce the digits of a BigDecimal.
|
|
|
|
* The behavior of BigDecimal#coerce with a Rational is changed. It uses
|
|
the precision of the receiver BigDecimal to produce the digits of a
|
|
BigDecimal from the given Rational.
|
|
|
|
* bigdecimal/util
|
|
|
|
* BigDecimal#to_d and Integer#to_d are added.
|
|
|
|
* Float#to_d accepts a precision.
|
|
|
|
* Rational#to_d raises ArgumentError when passing zero or negative
|
|
precision.
|
|
|
|
* Rational#to_d
|
|
|
|
* Zero and an implicit precision is deprecated.
|
|
This feature is removed at the next release of bigdecimal.
|
|
|
|
* A negative precision isn't supported.
|
|
Be careful it is an incompatible change.
|
|
|
|
* date
|
|
|
|
* Accepts flonum explicitly with limitations.
|
|
* If the given offset is flonum, DateTime assumes its precision is
|
|
at most second.
|
|
|
|
DateTime.new(2001,2,3,0,0,0,3.0/24) ==
|
|
DateTime.new(2001,2,3,0,0,0,'+03:00')
|
|
#=> true
|
|
|
|
* If the given operand for -/+ is flonum, DateTime assumes its
|
|
precision is at most nanosecond.
|
|
|
|
DateTime.new(2001,2,3) + 0.5 == DateTime.new(2001,2,3,12)
|
|
#=> true
|
|
|
|
* Precision of offset is always at most second.
|
|
|
|
Rational('0.5') == Rational('0.500001') #=> false
|
|
DateTime.new(2001,2,3,0,0,0,Rational('0.5')) ==
|
|
DateTime.new(2001,2,3,0,0,0,Rational('0.500001'))
|
|
#=> true
|
|
|
|
* Ignores long offset and far reform day (with warning).
|
|
|
|
* Now accepts only:
|
|
|
|
-1<=offset<=1 (-24:00..+24:00)
|
|
2298874<=start<=2426355 or -/+oo
|
|
(proleptic Gregorian/Julian mean -/+oo)
|
|
|
|
* A method strftime cannot produce huge output (same as Time's one).
|
|
|
|
* Even though Date/DateTime can handle far dates, the following causes
|
|
an exception.
|
|
|
|
DateTime.new(1<<10000).strftime('%Y') # Errno::ERANGE
|
|
|
|
* Changed the format of inspect.
|
|
* Changed the format of marshal (but, can load old dumps).
|
|
|
|
* io/console
|
|
* new methods:
|
|
* IO#noecho {|io| }
|
|
* IO#echo=
|
|
* IO#echo?
|
|
* IO#raw {|io| }
|
|
* IO#raw!
|
|
* IO#getch
|
|
* IO#winsize
|
|
* IO.console
|
|
|
|
* json
|
|
* updated to v1.5.4.
|
|
|
|
* matrix
|
|
* new classes:
|
|
* Matrix::EigenvalueDecomposition
|
|
* Matrix::LUPDecomposition
|
|
* new methods:
|
|
* Matrix#diagonal?
|
|
* Matrix#eigen
|
|
* Matrix#eigensystem
|
|
* Matrix#hermitian?
|
|
* Matrix#lower_triangular?
|
|
* Matrix#lup
|
|
* Matrix#lup_decomposition
|
|
* Matrix#normal?
|
|
* Matrix#orthogonal?
|
|
* Matrix#permutation?
|
|
* Matrix#round
|
|
* Matrix#symmetric?
|
|
* Matrix#unitary?
|
|
* Matrix#upper_triangular?
|
|
* Matrix#zero?
|
|
* Vector#magnitude, #norm
|
|
* Vector#normalize
|
|
* extended methods:
|
|
* Matrix#each and #each_with_index can iterate on a subset of the elements
|
|
* Matrix#find_index returns [row, column] and can iterate on a subset
|
|
of the elements
|
|
* Matrix#** implements Numeric exponents (using the eigensystem)
|
|
* Matrix.zero can build rectangular matrices
|
|
|
|
* minitest
|
|
* Minitest has been updated to version 2.2.2.
|
|
* For full details, see https://github.com/seattlerb/minitest/blob/master/History.txt
|
|
|
|
* net/http
|
|
* SNI (Server Name Indication) supported for HTTPS.
|
|
|
|
* Allow to configure to wait server returning '100 continue' response
|
|
before sending HTTP request body. Set Net::HTTP#continue_timeout AND pass
|
|
'expect' => '100-continue' to a extra HTTP header.
|
|
|
|
For example, the following code sends HTTP header and waits for getting
|
|
'100 continue' response before sending HTTP request body. When 0.5 [sec]
|
|
timeout occurs or the server send '100 continue', the client sends HTTP
|
|
request body.
|
|
http.continue_timeout = 0.5
|
|
http.request_post('/continue', 'body=BODY', 'expect' => '100-continue')
|
|
|
|
* new method:
|
|
* Net::HTTPRequest#set_form): Added to support
|
|
both application/x-www-form-urlencoded and multipart/form-data.
|
|
|
|
* objspace
|
|
* new method:
|
|
* ObjectSpace::memsize_of_all
|
|
|
|
* openssl
|
|
* PKey::RSA and PKey::DSA now use the generic X.509 encoding scheme
|
|
(e.g. used in a X.509 certificate's Subject Public Key Info) when
|
|
exporting public keys to DER or PEM. Backward compatibility is
|
|
ensured by (already existing) fallbacks during creation.
|
|
* OpenSSL::ASN1::Constructive#new and OpenSSL::ASN1::Primitive#new
|
|
(and the constructors of their sub-classes) will no longer force
|
|
tagging to be set to :EXPLICIT when tag and/or tag_class are passed
|
|
as parameters. tagging must be set explicitly.
|
|
* Support for infinite length encodings via infinite_length attribute.
|
|
* OpenSSL::PKey.read( file | string [, pwd] ) allows to read arbitrary
|
|
public/private keys in DER-/PEM-encoded form with an optional password
|
|
for encrypted PEM encodings.
|
|
* Add new method OpenSSL::X509::Name#hash_old as a wrapper of
|
|
X509_NAME_hash_old() defined from OpenSSL 1.0.0. It returns OpenSSL 0.9.8
|
|
compatible hash value.
|
|
|
|
* optparse
|
|
* support for bash/zsh completion.
