|
||||
|
||||
* Signal
|
||||
* added method:
|
||||
* added Signal.signame which returns signal name
|

|
||||
are specified.
|
||||
|
||||
* String
|
||||
* added method:
|
||||

|
||||
* change return value:
|
||||
* String#lines now returns an array instead of an enumerator.
|
||||
* String#chars now returns an array instead of an enumerator.
|
||||

|
||||
|

|
||||
instance variable names.
|
||||
|
||||
* Thread
|
||||
* added method:
|
||||
* added Thread#thread_variable_get for getting thread local variables
|
||||
(these are different than Fiber local variables).
|
||||
* added Thread#thread_variable_set for setting thread local variables.
|
||||
* added Thread#thread_variables for getting a list of the thread local
|
||||
variable keys.
|
||||
* added Thread#thread_variable? for testing to see if a particular thread
|
||||

|
||||
* added Thread.handle_interrupt as well as instance and singleton methods
|
||||

|
||||
* added Thread#backtrace_locations which returns similar information of
|
||||
Kernel#caller_locations.
|
||||
* new class Thread::Backtrace::Location to hold backtrace location
|
||||
information. These are returned by Thread#backtrace_locations and
|
||||
Kernel#caller_locations.
|
||||
* incompatible changes:
|
||||
* Thread#join and Thread#value now raises a ThreadError if target thread
|
||||
is the current or main thread.
|
||||
|
||||
* Time
|

|
||||
* Time#to_s now returns US-ASCII encoding instead of BINARY.
|

|
||||
|
||||
=== Core classes compatibility issues (excluding feature bug fixes)
|
||||
|
||||
* Array#values_at
|
||||
|
||||
See above.
|
||||
|
||||
* String#lines
|
||||
* String#chars
|
||||
* String#codepoints
|
||||
* String#bytes
|
||||
|
||||
These methods no longer return an Enumerator, although passing a
|
||||
block is still supported for backwards compatibility.
|
||||
|
||||
Code like str.lines.with_index(1) { |line, lineno| ... } no longer
|
||||
works because str.lines returns an array. Replace lines with
|
||||
each_line in such cases.
|
||||
|
||||
* IO#lines
|
||||
* IO#chars
|
||||
* IO#codepoints
|
||||
* IO#bytes
|
||||
* ARGF#lines
|
||||
* ARGF#chars
|
||||
* ARGF#bytes
|
||||
* StringIO#lines
|
||||
* StringIO#chars
|
||||
* StringIO#codepoints
|
||||
* StringIO#bytes
|
||||
* Zlib::GzipReader#lines
|
||||
* Zlib::GzipReader#bytes
|
||||
|
||||
These methods are deprecated in favor of each_line, each_byte,
|
||||
each_char and each_codepoint.
|
||||
|
||||
* Proc#==
|
||||
* Proc#eql?
|
||||
|
||||
These methods were removed. Two procs are == only when they are
|
||||
the same object.
|
||||
|
||||
* Fixnum
|
||||
* Bignum
|
||||
* Float
|
||||
|
||||
Fixnums, Bignums and Floats are frozen.
|
||||
|
||||
* Signal.trap
|
||||
|
||||
See above.
|
||||
|
||||
* Merge Onigmo.
|
||||
https://github.com/k-takata/Onigmo
|
||||
|
||||
* The :close_others option is true by default for system() and exec().
|
||||
Also, the close-on-exec flag is set by default for all new file descriptors.
|
||||
This means file descriptors doesn't inherit to spawned process unless
|
||||
explicitly requested such as system(..., fd=>fd).
|
||||
|
||||
* Kernel#respond_to? against a protected method now returns false
|
||||
unless the second argument is true.
|
||||
|
||||
* Kernel#respond_to_missing?
|
||||
* Kernel#initialize_clone
|
||||
* Kernel#initialize_dup
|
||||
|
||||
These methods are now private.
|
||||
|
||||
* Thread#join, Thread#value
|
||||
|
||||
See above.
|
||||
|
||||
* Mutex#lock, Mutex#unlock, Mutex#try_lock, Mutex#synchronize and Mutex#sleep
|
||||
|
||||
See above.
|
||||
|
||||
=== Stdlib updates (outstanding ones only)
|
||||
|
||||
* cgi
|
||||
* Add HTML5 tag maker.
|
||||
* CGI#header has been renamed to CGI#http_header and
|
||||
aliased to CGI#header.
|
||||
* When HTML5 tagmaker called, overwrite CGI#header,
|
||||
CGI#header function is to create a <header> element.
|
||||
|
||||
* CSV
|
||||
* Removed CSV::dump and CSV::load to protect users from dangerous
|
||||
serialization vulnerability
|
||||
|
||||
* iconv
|
||||
* Iconv has been removed. Use String#encode instead.
|
||||
|
||||
* io/console
|
||||
* new methods:
|
||||
* added IO#cooked which sets the terminal to cooked mode within the given block.
|
||||
* added IO#cooked! which sets the terminal to cooked.
|
||||
* extended method:
|
||||
* IO#raw, IO#raw!, and IO#getch accept keyword arguments, :min and :time.
|
||||
|
||||
* io/wait
|
||||
* new features:
|
||||
* added IO#wait_writable method.
|
||||
* added IO#wait_readable method as alias of IO#wait.
|
||||
|
||||
* json
|
||||
* updated to 1.7.7.
|
||||
|
||||
* net/http
|
||||
* new features:
|
||||
* Proxies are now automatically detected from the http_proxy environment
|
||||
variable. See Net::HTTP::new for details.
|
||||
* gzip and deflate compression are now requested for all requests by
|
||||
default. See Net::HTTP for details.
|
||||
* SSL sessions are now reused across connections for a single instance.
|
||||
This speeds up connection by using a previously negotiated session.
|
||||
* Requests may be created from a URI which sets the request_uri and host
|
||||
header of the request (but does not change the host connected to).
|
||||
* Responses contain the URI requested which allows easier implementation of
|
||||
redirect following.
|
||||
* new methods:
|
||||
* Net::HTTP#local_host
|
||||
* Net::HTTP#local_host=
|
||||
* Net::HTTP#local_port
|
||||
* Net::HTTP#local_port=
|
||||
* extended method:
|
||||
* Net::HTTP#connect uses local_host and local_port if specified.
|
||||
|
||||
* net/imap
|
||||
* new methods:
|
||||
* Net::IMAP.default_port
|
||||
* Net::IMAP.default_imap_port
|
||||
* Net::IMAP.default_tls_port
|
||||
* Net::IMAP.default_ssl_port
|
||||
* Net::IMAP.default_imaps_port
|
||||
|
||||
* objspace
|
||||
* new method:
|
||||
* ObjectSpace.reachable_objects_from(obj)
|
||||
|
||||
* openssl
|
||||
* Consistently raise an error when trying to encode nil values. All instances
|
||||
of OpenSSL::ASN1::Primitive now raise TypeError when calling to_der on an
|
||||
instance whose value is nil. All instances of OpenSSL::ASN1::Constructive
|
||||
raise NoMethodError in the same case. Constructing such values is still
|
||||
permitted.
|
||||
* TLS 1.1 & 1.2 support by setting OpenSSL::SSL::SSLContext#ssl_version to
|
||||
:TLSv1_2, :TLSv1_2_server, :TLSv1_2_client or :TLSv1_1, :TLSv1_1_server
|
||||
:TLSv1_1_client. The version being effectively used can be queried
|
||||
with OpenSSL::SSL#ssl_version. Furthermore, it is also possible to
|
||||
blacklist the new TLS versions with OpenSSL::SSL:OP_NO_TLSv1_1 and
|
||||
OpenSSL::SSL::OP_NO_TLSv1_2.
|
||||
* Added OpenSSL::SSL::SSLContext#renegotiation_cb. A user-defined callback
|
||||
may be set which gets called whenever a new handshake is negotiated. This
|
||||
also allows to programmatically decline (client) renegotiation attempts.
|
||||
* Support for "0/n" splitting of records as BEAST mitigation via
|
||||
OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS.
|
||||
* The default options for OpenSSL::SSL::SSLContext have changed to
|
||||
OpenSSL::SSL::OP_ALL & ~OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS
|
||||
instead of OpenSSL::SSL::OP_ALL only. This enables the countermeasure for
|
||||
the BEAST attack by default.
|
||||
* OpenSSL requires passwords for decrypting PEM-encoded files to be at least
|
||||
four characters long. This led to awkward situations where an export with
|
||||
a password with fewer than four characters was possible, but accessing the
|
||||
file afterwards failed. OpenSSL::PKey::RSA, OpenSSL::PKey::DSA and
|
||||
OpenSSL::PKey::EC therefore now enforce the same check when exporting a
|
||||
private key to PEM with a password - it has to be at least four characters
|
||||
long.
|
||||
* SSL/TLS support for the Next Protocol Negotiation extension. Supported
|
||||
with OpenSSL 1.0.1 and higher.
|
||||
* OpenSSL::OPENSSL_FIPS allows client applications to detect whether OpenSSL
|
||||
is FIPS-enabled. OpenSSL.fips_mode= allows turning on and off FIPS mode
|
||||
manually in order to adapt to situations where FIPS mode would be an
|
||||
explicit requirement.
|
||||
* Authenticated Encryption with Associated Data (AEAD) is supported via
|
||||
Cipher#auth_data= and Cipher#auth_tag/Cipher#auth_tag=.
|
||||
Currently (OpenSSL 1.0.1c), only GCM mode is supported.
|
||||
|
||||
* ostruct
|
||||
* new methods:
|
||||
* OpenStruct#[], []=
|
||||
* OpenStruct#each_pair
|
||||
* OpenStruct#eql?
|
||||
* OpenStruct#hash
|
||||
* OpenStruct#to_h converts the struct to a hash.
|
||||
* extended method:
|
||||
* OpenStruct.new also accepts an OpenStruct / Struct.
|
||||
|
||||
* pathname
|
||||
* extended method:
|
||||
* Pathname#find returns an enumerator if no block is given.
|
||||
|
||||
* rake
|
||||
* rake has been updated to version 0.9.5.
|
||||
|
||||
This version is backwards-compatible with previous rake versions and
|
||||
contains many bug fixes.
|
||||
|
||||
See
|
||||
http://rake.rubyforge.org/doc/release_notes/rake-0_9_5_rdoc.html for a list
|
||||
of changes in rake 0.9.3, 0.9.4 and 0.9.5.
|
||||
|
||||
* RDoc
|
||||
* RDoc has been updated to version 4.0
|
||||
|
||||
This version is largely backwards-compatible with previous rdoc versions.
|
||||
The most notable change is an update to the ri data format (ri data must
|
||||
be regenerated for gems shared across rdoc versions). Further API changes
|
||||
are internal and won't affect most users.
|
||||
|
||||
Notable changes include:
|
||||
|
||||
* Page support for ri. Try `ri ruby:` for a list of pages in ruby or
|
||||
`ri ruby:syntax/literals` for the syntax documentation for literals.
|
||||
|
||||
This also works for gems such as `ri rspec:README` for the rspec gem's
|
||||
README file.
|
||||
* Markdown support. See ri RDoc::Markdown for details.
|
||||
|
||||
See https://github.com/rdoc/rdoc/blob/master/History.rdoc for a full list
|
||||
of changes in rdoc 4.0.
|
||||
|
||||
* resolv
|
||||
* new methods:
|
||||
* Resolv::DNS#timeouts=
|
||||
* Resolv::DNS::Config#timeouts=
|
||||
|
||||
* rexml
|
||||
* REXML::Document#write supports Hash arguments.
|
||||
* REXML::Document#write supports new :encoding option. It changes
|
||||
XML document encoding. Without :encoding option, encoding in
|
||||
XML declaration is used for XML document encoding.
|
||||
|
||||
* RubyGems
|
||||
* Updated to 2.0.0
|
||||
|
||||
RubyGems 2.0.0 features the following improvements:
|
||||
|
||||
* Improved support for default gems shipping with ruby 2.0.0+
|
||||
* A gem can have arbitrary metadata through Gem::Specification#metadata
|
||||
* `gem search` now defaults to --remote and is anchored like gem list.
|
||||
* Added --document to replace --rdoc and --ri. Use --no-document to
|
||||
disable documentation, --document=rdoc to only generate rdoc.
|
||||
* Only ri-format documentation is generated by default.
|
||||
* `gem server` uses RDoc::Servlet from RDoc 4.0 to generate HTML
|
||||
documentation.

|
||||
https://github.com/rubygems/rubygems/blob/master/History.txt
|
||||
|
||||
* shellwords
|
||||
* Shellwords#shellescape now stringifies the given object using to_s.
|
||||
* Shellwords#shelljoin accepts non-string objects in the given
|
||||
array, each of which is stringified using to_s.
|
||||
|
||||
* stringio
|
||||
* deprecated methods:
|
||||
* StringIO#lines, #bytes, #chars and #codepoints are deprecated.
|
||||
|
||||
* syslog
|
||||
* Added Syslog::Logger which provides a Logger API atop Syslog.
|
||||
* Syslog::Priority, Syslog::Level, Syslog::Option and Syslog::Macros
|
||||
are introduced for easy detection of available constants on a
|
||||
running system.
|
||||
|
||||
* tmpdir
|
||||
* incompatible changes:
|
||||
* Dir.mktmpdir uses FileUtils.remove_entry instead of
|
||||
FileUtils.remove_entry_secure. This means that applications should not
|
||||
change the permission of the created temporary directory to make
|
||||
accessible from other users.
|
||||
|
||||
* yaml
|
||||
* Syck has been removed. YAML now completely depends on libyaml being
|
||||
installed.
|
||||
* libyaml is now bundled with ruby, for cases where the library is not
|
||||
installed locally.
|
||||
|
||||
* zlib
|
||||
* Added streaming support for Zlib::Inflate and Zlib::Deflate. This allows
|
||||
processing of a stream without the use of large amounts of memory.
|
||||
* Added support for the new deflate strategies Zlib::RLE and Zlib::FIXED.
|
||||
* Zlib streams are now processed without the GVL. This allows gzip, zlib and
|
||||
deflate streams to be processed in parallel.
|
||||
* deprecated methods:
|
||||
* Zlib::GzipReader#lines and #bytes are deprecated.
|
||||
|
||||
=== Stdlib compatibility issues (excluding feature bug fixes)
|
||||
|
||||
* OpenStruct new methods can conflict with custom attributes named
|
||||
"each_pair", "eql?", "hash" or "to_h".
|
||||
|
||||
* Dir.mktmpdir in lib/tmpdir.rb
|
||||
|
||||
See above.
|
||||
|
||||
=== C API updates
|
||||
|
||||
* NUM2SHORT() and NUM2USHORT() added. They are similar to NUM2INT, but short.
|
||||
|
||||
* rb_newobj_of() and NEWOBJ_OF() added. They create a new object of a given class.

|
||||
* change return value:
|
||||
* String#lines now returns an array instead of an enumerator.

|
||||
|

|
||||
|
||||
* Thread
|
||||
* added method:
|
||||
* added Thread#thread_variable_get for getting thread local variables
|
||||
(these are different than Fiber local variables).
|
||||
* added Thread#thread_variable_set for setting thread local variables.
|
||||
* added Thread#thread_variables for getting a list of the thread local
|
||||
variable keys.
|
||||
* added Thread#thread_variable? for testing to see if a particular thread
|
||||

|
||||
* added Thread.handle_interrupt as well as instance and singleton methods
|
||||

|
||||
* added Thread#backtrace_locations which returns similar information of
|
||||
Kernel#caller_locations.
|
||||
* new class Thread::Backtrace::Location to hold backtrace location
|
||||
information. These are returned by Thread#backtrace_locations and
|
||||
Kernel#caller_locations.
|
||||
* incompatible changes:
|
||||
* Thread#join and Thread#value now raises a ThreadError if target thread
|
||||
is the current or main thread.
|
||||
|
||||
* Time
|
||||

|
||||
* Time#to_s now returns US-ASCII encoding instead of BINARY.

=== Core classes compatibility issues (excluding feature bug fixes)
|
||||
|
||||
* Array#values_at
|
||||
|
||||
See above.
|
||||
|
||||
* String#lines
|
||||
* String#chars
|
||||
* String#codepoints
|
||||
* String#bytes
|
||||
|
||||
These methods no longer return an Enumerator, although passing a
|
||||
block is still supported for backwards compatibility.
|
||||
|
||||
Code like str.lines.with_index(1) { |line, lineno| ... } no longer
|
||||
works because str.lines returns an array. Replace lines with
|
||||
each_line in such cases.
|
||||
|
||||
* IO#lines
|
||||
* IO#chars
|
||||
* IO#codepoints
|
||||
* IO#bytes
|
||||
* ARGF#lines
|
||||
* ARGF#chars
|
||||
* ARGF#bytes
|
||||
* StringIO#lines
|
||||
* StringIO#chars
|
||||
* StringIO#codepoints
|
||||
* StringIO#bytes
|
||||
* Zlib::GzipReader#lines
|
||||
* Zlib::GzipReader#bytes
|
||||
|
||||
These methods are deprecated in favor of each_line, each_byte,
|
||||
each_char and each_codepoint.
|
||||
|
||||
* Proc#==
|
||||
* Proc#eql?
|
||||
|
||||
These methods were removed. Two procs are == only when they are
|
||||
the same object.
|
||||
|
||||
* Fixnum
|
||||
* Bignum
|
||||
* Float
|
||||
|
||||
Fixnums, Bignums and Floats are frozen.
|
||||
|
||||
* Signal.trap
|
||||
|
||||
See above.
|
||||
|
||||
* Merge Onigmo.
|
||||
https://github.com/k-takata/Onigmo
|
||||
|
||||
* The :close_others option is true by default for system() and exec().
|
||||
Also, the close-on-exec flag is set by default for all new file descriptors.
|
||||
This means file descriptors doesn't inherit to spawned process unless
|
||||
explicitly requested such as system(..., fd=>fd).
|
||||
|
||||
* Kernel#respond_to? against a protected method now returns false
|
||||
unless the second argument is true.
|
||||
|
||||
* Kernel#respond_to_missing?
|
||||
* Kernel#initialize_clone
|
||||
* Kernel#initialize_dup
|
||||
|
||||
These methods are now private.
|
||||
|
||||
* Thread#join, Thread#value
|
||||
|
||||
See above.
|
||||
|
||||
* Mutex#lock, Mutex#unlock, Mutex#try_lock, Mutex#synchronize and Mutex#sleep
|
||||
|
||||
See above.
|
||||
|
||||
=== Stdlib updates (outstanding ones only)
|
||||
|
||||
* cgi
|
||||
* Add HTML5 tag maker.
|
||||
* CGI#header has been renamed to CGI#http_header and
|
||||
aliased to CGI#header.
|
||||
* When HTML5 tagmaker called, overwrite CGI#header,
|
||||
CGI#header function is to create a <header> element.
|
||||
|
||||
* CSV
|
||||
* Removed CSV::dump and CSV::load to protect users from dangerous
|
||||
serialization vulnerability
|
||||
|
||||
* iconv
|
||||
* Iconv has been removed. Use String#encode instead.
|
||||
|
||||
* io/console
|
||||
* new methods:
|
||||
* added IO#cooked which sets the terminal to cooked mode within the given block.
|
||||
* added IO#cooked! which sets the terminal to cooked.
|
||||
* extended method:
|
||||
* IO#raw, IO#raw!, and IO#getch accept keyword arguments, :min and :time.
|
||||
|
||||
* io/wait
|
||||
* new features:
|
||||
* added IO#wait_writable method.
|
||||
* added IO#wait_readable method as alias of IO#wait.
|
||||
|
||||
* json
|
||||
* updated to 1.7.7.
|
||||
|
||||
* net/http
|
||||
* new features:
|
||||
* Proxies are now automatically detected from the http_proxy environment
|
||||
variable. See Net::HTTP::new for details.
|
||||
* gzip and deflate compression are now requested for all requests by
|
||||
default. See Net::HTTP for details.
|
||||
* SSL sessions are now reused across connections for a single instance.
|
||||
This speeds up connection by using a previously negotiated session.
|
||||
* Requests may be created from a URI which sets the request_uri and host
|
||||
header of the request (but does not change the host connected to).
|
||||
* Responses contain the URI requested which allows easier implementation of
|
||||
redirect following.
|
||||
* new methods:
|
||||
* Net::HTTP#local_host
|
||||
* Net::HTTP#local_host=
|
||||
* Net::HTTP#local_port
|
||||
* Net::HTTP#local_port=
|
||||
* extended method:
|
||||
* Net::HTTP#connect uses local_host and local_port if specified.
|
||||
|
||||
* net/imap
|
||||
* new methods:
|
||||
* Net::IMAP.default_port
|
||||
* Net::IMAP.default_imap_port
|
||||
* Net::IMAP.default_tls_port
|
||||
* Net::IMAP.default_ssl_port
|
||||
* Net::IMAP.default_imaps_port
|
||||
|
||||
* objspace
|
||||
* new method:
|
||||
* ObjectSpace.reachable_objects_from(obj)
|
||||
|
||||
* openssl
|
||||
* Consistently raise an error when trying to encode nil values. All instances
|
||||
of OpenSSL::ASN1::Primitive now raise TypeError when calling to_der on an
|
||||
instance whose value is nil. All instances of OpenSSL::ASN1::Constructive
|
||||
raise NoMethodError in the same case. Constructing such values is still
|
||||
permitted.
|
||||
* TLS 1.1 & 1.2 support by setting OpenSSL::SSL::SSLContext#ssl_version to
|
||||
:TLSv1_2, :TLSv1_2_server, :TLSv1_2_client or :TLSv1_1, :TLSv1_1_server
|
||||
:TLSv1_1_client. The version being effectively used can be queried
|
||||
with OpenSSL::SSL#ssl_version. Furthermore, it is also possible to
|
||||
blacklist the new TLS versions with OpenSSL::SSL:OP_NO_TLSv1_1 and
|
||||
OpenSSL::SSL::OP_NO_TLSv1_2.
|
||||
* Added OpenSSL::SSL::SSLContext#renegotiation_cb. A user-defined callback
|
||||
may be set which gets called whenever a new handshake is negotiated. This
|
||||
also allows to programmatically decline (client) renegotiation attempts.
|
||||
* Support for "0/n" splitting of records as BEAST mitigation via
|
||||
OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS.
|
||||
* The default options for OpenSSL::SSL::SSLContext have changed to
|
||||
OpenSSL::SSL::OP_ALL & ~OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS
|
||||
instead of OpenSSL::SSL::OP_ALL only. This enables the countermeasure for
|
||||
the BEAST attack by default.
|
||||
* OpenSSL requires passwords for decrypting PEM-encoded files to be at least
|
||||
four characters long. This led to awkward situations where an export with
|
||||
a password with fewer than four characters was possible, but accessing the
|
||||
file afterwards failed. OpenSSL::PKey::RSA, OpenSSL::PKey::DSA and
|
||||
OpenSSL::PKey::EC therefore now enforce the same check when exporting a
|
||||
private key to PEM with a password - it has to be at least four characters
|
||||
long.
|
||||
* SSL/TLS support for the Next Protocol Negotiation extension. Supported
|
||||
with OpenSSL 1.0.1 and higher.
|
||||
* OpenSSL::OPENSSL_FIPS allows client applications to detect whether OpenSSL
|
||||
is FIPS-enabled. OpenSSL.fips_mode= allows turning on and off FIPS mode
|
||||
manually in order to adapt to situations where FIPS mode would be an
|
||||
explicit requirement.
|
||||
* Authenticated Encryption with Associated Data (AEAD) is supported via
|
||||
Cipher#auth_data= and Cipher#auth_tag/Cipher#auth_tag=.
|
||||
Currently (OpenSSL 1.0.1c), only GCM mode is supported.
|
||||
|
||||
* ostruct
|
||||
* new methods:
|
||||
* OpenStruct#[], []=
|
||||
* OpenStruct#each_pair
|
||||
* OpenStruct#eql?
|
||||
* OpenStruct#hash
|
||||
* OpenStruct#to_h converts the struct to a hash.
|
||||
* extended method:
|
||||
* OpenStruct.new also accepts an OpenStruct / Struct.
|
||||
|
||||
* pathname
|
||||
* extended method:
|
||||
* Pathname#find returns an enumerator if no block is given.
|
||||
|
||||
* rake
|
||||
* rake has been updated to version 0.9.5.
|
||||
|
||||
This version is backwards-compatible with previous rake versions and
|
||||
contains many bug fixes.
|
||||
|
||||
See
|
||||
http://rake.rubyforge.org/doc/release_notes/rake-0_9_5_rdoc.html for a list
|
||||
of changes in rake 0.9.3, 0.9.4 and 0.9.5.
|
||||
|
||||
* RDoc
|
||||
* RDoc has been updated to version 4.0
|
||||
|
||||
This version is largely backwards-compatible with previous rdoc versions.
|
||||
The most notable change is an update to the ri data format (ri data must
|
||||
be regenerated for gems shared across rdoc versions). Further API changes
|
||||
are internal and won't affect most users.
|
||||
|
||||
Notable changes include:
|
||||
|
||||
* Page support for ri. Try `ri ruby:` for a list of pages in ruby or
|
||||
`ri ruby:syntax/literals` for the syntax documentation for literals.
|
||||
|
||||
This also works for gems such as `ri rspec:README` for the rspec gem's
|
||||
README file.
|
||||
* Markdown support. See ri RDoc::Markdown for details.
|
||||
|
||||
See https://github.com/rdoc/rdoc/blob/master/History.rdoc for a full list
|
||||
of changes in rdoc 4.0.
|
||||
|
||||
* resolv
|
||||
* new methods:
|
||||
* Resolv::DNS#timeouts=
|
||||
* Resolv::DNS::Config#timeouts=
|
||||
|
||||
* rexml
|
||||
* REXML::Document#write supports Hash arguments.
|
||||
* REXML::Document#write supports new :encoding option. It changes
|
||||
XML document encoding. Without :encoding option, encoding in
|
||||
XML declaration is used for XML document encoding.
|
||||
|
||||
* RubyGems
|
||||
* Updated to 2.0.0
|
||||
|
||||
RubyGems 2.0.0 features the following improvements:
|
||||
|
||||
* Improved support for default gems shipping with ruby 2.0.0+
|
||||
* A gem can have arbitrary metadata through Gem::Specification#metadata
|
||||
* `gem search` now defaults to --remote and is anchored like gem list.
|
||||
* Added --document to replace --rdoc and --ri. Use --no-document to
|
||||
disable documentation, --document=rdoc to only generate rdoc.
|
||||
* Only ri-format documentation is generated by default.
|
||||
* `gem server` uses RDoc::Servlet from RDoc 4.0 to generate HTML
|
||||
documentation.
|
||||

|
||||
|
||||
* shellwords
|
||||
* Shellwords#shellescape now stringifies the given object using to_s.
|
||||
* Shellwords#shelljoin accepts non-string objects in the given
|
||||
array, each of which is stringified using to_s.
|
||||
|
||||
* stringio
|
||||
* deprecated methods:
|
||||
* StringIO#lines, #bytes, #chars and #codepoints are deprecated.
|
||||
|
||||
* syslog
|
||||
* Added Syslog::Logger which provides a Logger API atop Syslog.
|
||||
* Syslog::Priority, Syslog::Level, Syslog::Option and Syslog::Macros
|
||||
are introduced for easy detection of available constants on a
|
||||
running system.
|
||||
|
||||
* tmpdir
|
||||
* incompatible changes:
|
||||
* Dir.mktmpdir uses FileUtils.remove_entry instead of
|
||||
FileUtils.remove_entry_secure. This means that applications should not
|
||||
change the permission of the created temporary directory to make
|
||||
accessible from other users.
|
||||
|
||||
* yaml
|
||||
* Syck has been removed. YAML now completely depends on libyaml being
|
||||
installed.
|
||||
* libyaml is now bundled with ruby, for cases where the library is not
|
||||
installed locally.
|
||||
|
||||
* zlib
|
||||
* Added streaming support for Zlib::Inflate and Zlib::Deflate. This allows
|
||||
processing of a stream without the use of large amounts of memory.
|
||||
* Added support for the new deflate strategies Zlib::RLE and Zlib::FIXED.
|
||||
* Zlib streams are now processed without the GVL. This allows gzip, zlib and
|
||||
deflate streams to be processed in parallel.
|
||||
* deprecated methods:
|
||||
* Zlib::GzipReader#lines and #bytes are deprecated.
|
||||
|
||||
=== Stdlib compatibility issues (excluding feature bug fixes)
|
||||
|
||||
* OpenStruct new methods can conflict with custom attributes named
|
||||
"each_pair", "eql?", "hash" or "to_h".
|
||||
|
||||
* Dir.mktmpdir in lib/tmpdir.rb
|
||||
|
||||
See above.
|
||||
|
||||
=== C API updates
|
||||
|
||||
* NUM2SHORT() and NUM2USHORT() added. They are similar to NUM2INT, but short.
|
||||
|
||||
* rb_newobj_of() and NEWOBJ_OF() added. They create a new object of a given class.
