CHANGELOG

*Rails 3.1.0 (unreleased)*

• ActiveSupport::Dependencies#load and ActiveSupport::Dependencies#require now

return the value from `super` [Aaron Patterson]

• Fixed ActiveSupport::Gzip to work properly in Ruby 1.8 [Guillermo Iguaran]

• Kernel.require_library_or_gem was deprecated and will be removed in Rails 3.2.0 [Josh Kalderimis]

• ActiveSupport::Duration#duplicable? was fixed for Ruby 1.8 [thedarkone]

• ActiveSupport::BufferedLogger set log encoding to BINARY, but still use text

mode to output portable newlines. [fxn]

• ActiveSupport::Dependencies now raises NameError if it finds an existing constant in load_missing_constant. This better reflects the nature of the error which is usually caused by calling constantize on a nested constant. [Andrew White]

• Deprecated ActiveSupport::SecureRandom in favour of SecureRandom from the standard library [Jon Leighton]

• New reporting method Kernel#quietly. [fxn]

• Add String#inquiry as a convenience method for turning a string into a StringInquirer object [DHH]

• Add Object#in? to test if an object is included in another object [Prem Sichanugrist, Brian Morearty, John Reitano]

• LocalCache strategy is now a real middleware class, not an anonymous class

posing for pictures.

• ActiveSupport::Dependencies::ClassCache class has been introduced for

holding references to reloadable classes.

• ActiveSupport::Dependencies::Reference has been refactored to take direct

advantage of the new ClassCache.

• Backports Range#cover? as an alias for Range#include? in Ruby 1.8 [Diego Carrion, fxn]

• Added weeks_ago and prev_week to Date/DateTime/Time. [Rob Zolkos, fxn]

• Added before_remove_const callback to ActiveSupport::Dependencies.remove_unloadable_constants! [Andrew White]

• JSON decoding now uses the multi_json gem which also vendors a json engine called OkJson. The yaml backend has been removed in favor of OkJson as a default engine for 1.8.x, while the built in 1.9.x json implementation will be used by default. [Josh Kalderimis]

*Rails 3.0.7 (April 18, 2011)*

• Hash.from_xml no longer loses attributes on tags containing only whitespace [André Arko]

*Rails 3.0.6 (April 5, 2011)

• No changes.

*Rails 3.0.5 (February 26, 2011)*

• No changes.

*Rails 3.0.4 (February 8, 2011)*

• No changes.

*Rails 3.0.3 (November 16, 2010)*

• No changes.

*Rails 3.0.2 (November 15, 2010)*

• Added before_remove_const callback to ActiveSupport::Dependencies.remove_unloadable_constants! [Andrew White]

*Rails 3.0.1 (October 15, 2010)*

• No Changes, just a version bump.

*Rails 3.0.0 (August 29, 2010)*

• Implemented String#strip_heredoc. [fxn]

• Pluggable cache stores: setting config.cache_store = “custom_store” will require ‘active_support/cache/custom_store’ and look for the CustomStore constant. #5486 [Mike Perham]

• Removed Object#returning, Object#tap should be used instead. [Santiago Pastorino]

• Deprecation behavior is no longer hardcoded to the name of the environment. Instead, it is set via config.active_support.deprecation and can be one of :log, :stderr or :notify. :notify is a new style that sends the warning via ActiveSupport::Notifications, and is the new default for production

  Yehuda Katz

• Renamed ActiveSupport::Dependecies.load_(once_)paths to autoload_(once_)paths. [fxn]

• Added ActiveSupport::FileUpdateChecker to execute a block only if a set of files changed, used by Router and I18n locale files. [José Valim]

• Added ActiveSupport::DescendantsTracker to track descendants with support to constants reloading. [José Valim]

• ActiveSupport::OrderedHash#merge and merge! accept a block. #4838 [Paul Mucur, fxn]

• Date#since, ago, beginning_of_day, end_of_day, and xmlschema honor now the user time zone if set. [Geoff Buesing]

• Extracted String#truncate from TextHelper#truncate [DHH]

• Ruby 1.9: support UTF-8 case folding. #4595 [Norman Clarke]

• Removes Array#rand and backports Array#sample from Ruby 1.9, thanks to Marc-Andre Lafortune. [fxn]

• Ruby 1.9: Renames last_(month|year) to prev_(month|year) in Date and Time. [fxn]

• Aliases Date#sunday to Date#end_of_week. [fxn]

• Backports Date#>> from 1.9 so that calculations do the right thing around the calendar reform. [fxn]

• Date#to_time handles properly years in the range 0..138. [fxn]

• Deprecate {{}} as interpolation syntax for I18n in favor of %{} [José Valim]

• Array#to_xml is more powerful and able to handle the same types as Hash#to_xml #4490 [Neeraj Singh]

• Harmonize the caching API and refactor the backends. #4452 [Brian Durand] All caches:

  • Add default options to initializer that will be sent to all read, write, fetch, exist?, increment, and decrement

  • Add support for the :expires_in option to fetch and write for all caches. Cache entries are stored with the create timestamp and a ttl so that expiration can be handled independently of the implementation.

  • Add support for a :namespace option. This can be used to set a global prefix for cache entries.

  • Deprecate expand_cache_key on ActiveSupport::Cache and move it to ActionController::Caching and ActionDispatch::Http::Cache since the logic in the method used some Rails specific environment variables and was only used by ActionPack classes. Not very DRY but there didn’t seem to be a good shared spot and ActiveSupport really shouldn’t be Rails specific.

  • Add support for :race_condition_ttl to fetch. This setting can prevent race conditions on fetch calls where several processes try to regenerate a recently expired entry at once.

  • Add support for :compress option to fetch and write which will compress any data over a configurable threshold.

  • Nil values can now be stored in the cache and are distinct from cache misses for fetch.

  • Easier API to create new implementations. Just need to implement the methods read_entry, write_entry, and delete_entry instead of overwriting existing methods.

  • Since all cache implementations support storing objects, update the docs to state that ActiveCache::Cache::Store implementations should store objects. Keys, however, must be strings since some implementations require that.

  • Increase test coverage.

  • Document methods which are provided as convenience but which may not be universally available.

  MemoryStore:

  • MemoryStore can now safely be used as the cache for single server sites.

  • Make thread safe so that the default cache implementation used by Rails is thread safe. The overhead is minimal and it is still the fastest store available.

  • Provide :size initialization option indicating the maximum size of the cache in memory (defaults to 32Mb).

  • Add prune logic that removes the least recently used cache entries to keep the cache size from exceeding the max.

  • Deprecated SynchronizedMemoryStore since it isn’t needed anymore.

  FileStore:

  • Escape key values so they will work as file names on all file systems, be consistent, and case sensitive

  • Use a hash algorithm to segment the cache into sub directories so that a large cache doesn’t exceed file system limits.

  • FileStore can be slow so implement the LocalCache strategy to cache reads for the duration of a request.

  • Add cleanup method to keep the disk from filling up with expired entries.

  • Fix increment and decrement to use file system locks so they are consistent between processes.

  MemCacheStore:

  • Support all keys. Previously keys with spaces in them would fail

  • Deprecate CompressedMemCacheStore since it isn’t needed anymore (use :compress => true)

• JSON: encode objects that don’t have a native JSON representation using to_hash, if available, instead of instance_values (the old fallback) or to_s (other encoders’ default). Encode BigDecimal and Regexp encode as strings to conform with other encoders. Try to transcode non-UTF-8 strings. [Jeremy Kemper]

• HashWithIndifferentAccess: remove inherited symbolize_keys! since its keys are always strings. [Santiago Pastorino]

• Improve transliteration quality. #4374 [Norman Clarke]

• Speed up and add Ruby 1.9 support for ActiveSupport::Multibyte::Chars#tidy_bytes. #4350 [Norman Clarke]

• Reduced load time by deferring configuration of classes using ActiveSupport::on_load(:component_name) [YK]

• Rename metaclass to singleton_class now that ruby-core has decided [JK]

• New assertions assert_blank and assert_present. #4299 [Juanjo Bazan]

• Use Object#singleton_class instead of metaclass. Prefer Ruby’s choice. [Jeremy Kemper]

• JSON backend for YAJL. Preferred if available. #2666 [Brian Lopez]

• Introduce class_attribute to declare inheritable class attributes. Writing an attribute on a subclass behaves just like overriding the superclass reader method. Unifies and replaces most usage of cattr_accessor, class_inheritable_attribute, superclass_delegating_attribute, and extlib_inheritable_attribute. [Jeremy Kemper, Yehuda Katz]

• Time#- with a DateTime argument behaves the same as with a Time argument, i.e. returns the difference between self and arg as a Float #3476 [Geoff Buesing]

• YAML serialization for OrderedHash. #3608 [Gregor Schmidt]

• Update bundled TZInfo to v0.3.16 [Geoff Buesing]

• Georgetown TimeZone is now mapped to “America/Guyana” instead of “America/Argentina/San_Juan” #1821 [Geoff Buesing, Reuben Sivan]

• Changed the default ActiveSupport.use_standard_json_time_format from false to true and

ActiveSupport.escape_html_entities_in_json from true to false to match previously announced Rails 3 defaults [DHH]

• Added Object#presence that returns the object if it’s present? otherwise returns nil [DHH/Colin Kelley]

• Add Enumerable#exclude? to bring parity to Enumerable#include? and avoid if !x.include?/else calls [DHH]

• Update Edinburgh TimeZone to use “Europe/London” instead of “Europe/Dublin” #3310 [Phil Ross]

• Update bundled TZInfo to v0.3.15 [Geoff Buesing]

• JSON: +Object#to_json+ calls as_json to coerce itself into something natively encodable like Hash, Integer, or String. Override as_json instead of to_json so you’re JSON library agnostic. [Jeremy Kemper]

• String to_time and to_datetime: handle fractional seconds #864 [Jason Frey]

• Update bundled TZInfo to v0.3.13 [Geoff Buesing]

• Allow MemCacheStore to be initialized with a MemCache-like object instead of addresses and options [Bryan Helmkamp]

• Change spelling of Kyev timezone to Kyiv #2613 [Alexander Dymo]

• Add ActiveSupport.parse_json_times to disable time parsing in JSON backends that don’t support it or don’t need it. [rick]

• Add pluggable JSON backends with support for the JSON gem. [rick]

  Example: ActiveSupport::JSON.backend = "JSONGem"

All internal Rails JSON encoding is now handled by ActiveSupport::JSON.encode().  Use of #to_json is not recommended, as it may clash with other libraries that overwrite it.  However, you can recover Rails specific functionality
if you really want to use #to_json.

   gem 'json'
   ActiveSupport::JSON.backend = "JSONGem"

   class ActiveRecord::Base
     alias to_json rails_to_json
   end

• require ‘active_support’ no longer orders the whole menu of core extensions. Ask for just what you need: e.g. require ‘active_support/core/time’ to use timezones, durations, and stdlib date/time extensions. [Jeremy Kemper]

• Removed rarely-used DRb cache store. [Jeremy Kemper]

• TimeWithZone.name returns ‘Time’, to further thwart type checking [Geoff Buesing]

• Time.local instances: Adding 24.hours across the DST boundary adds 24 hours instead of one day #2066 [Michael Curtis]

*2.3.2 [Final] (March 15, 2009)*

• XmlMini supports LibXML and Nokogiri backends. #2084, #2190 [Bart ten Brinke, Aaron Patterson]

  Example: XmlMini.backend = 'Nokogiri'

• Update bundled memcache-client from 1.5.0.5 to 1.6.4.99. See www.mikeperham.com/2009/02/15/memcache-client-performance/ [Mike Perham]

• Ruby 1.9.1p0 fix: URI.unescape can decode multibyte chars. #2033 [MOROHASHI Kyosuke]

• Time#to_s(:rfc822) uses formatted_offset instead of unreliable and non-standard %z directive #1899 [Zachary Zolton]

• Make TimeWithZone#to_formatted_s an alias to TimeWithZone#to_s #1796 [Levin Alexander]

• Introduce Array.wrap(foo) to wrap the argument in an array unless it’s already an array. Wraps nil as an empty array. Use instead of Array(foo) and foo.to_a since they treat String as Enumerable. [Jeremy Kemper]

• TimeWithZone#xmlschema accepts optional fraction_digits argument [#1725 state:resolved] [Nicholas Dainty]

• Object#tap shim for Ruby < 1.8.7. Similar to Object#returning, tap yields self then returns self. [Jeremy Kemper]

  array.select { ... }.tap(&:inspect).map { ... }

• TimeWithZone#- gives correct result with wrapped DateTime, and with DateTime argument [Geoff Buesing]

• Updated i18n gem to version 0.1.1 #1635 [Yaroslav Markin]

• I18n support for Array#to_sentence. Introduces support.array.words_connector, .two_words_connector, and .last_word_connector translation keys. #1397 [Akira Matsuda]

• Added ActiveSupport::OrderedHash#each_key and ActiveSupport::OrderedHash#each_value #1410 [Christoffer Sawicki]

• Added ActiveSupport::MessageVerifier and MessageEncryptor to aid users who need to store signed and/or encrypted messages. [Michael Koziarski]

• Update bundled TZInfo to 0.3.12 [Geoff Buesing]

• Added lambda merging to OptionMerger (especially useful with named_scope and with_options) #726 [Paweł Kondzior]

*2.2.1 [RC2] (November 14th, 2008)*

• Increment the version of our altered memcache-client to prevent confusion caused when the 1.5.0 gem is installed.

• Add ActiveSupport::Rescuable module abstracting ActionController::Base rescue_from features. [Norbert Crombach, Pratik Naik]

• Switch from String#chars to String#mb_chars for the unicode proxy. [Manfred Stienstra]

  This helps with 1.8.7 compatibility and also improves performance for some operations by reducing indirection.

• TimeWithZone wday, yday and to_date avoid trip through method_missing [Geoff Buesing]

• Added Time, Date, DateTime and TimeWithZone past?, future? and today? #720 [Clemens Kofler, Geoff Buesing]

• Fixed Sri Jayawardenepura time zone to map to Asia/Colombo [Jamis Buck]

• Added Inflector#parameterize for easy slug generation (“Donald E. Knuth”.parameterize => “donald-e-knuth”) #713 [Matt Darby]

• Changed cache benchmarking to be reported in milliseconds [David Heinemeier Hansson]

• Fix Ruby’s Time marshaling bug in pre-1.9 versions of Ruby: utc instances are now correctly unmarshaled with a utc zone instead of the system local zone [#900 state:resolved] [Luca Guidi, Geoff Buesing]

• Add Array#in_groups which splits or iterates over the array in specified number of groups. #579. [Adrian Mugnolo] Example:

  a = (1..10).to_a a.in_groups(3) # => [[1, 2, 3, 4], [5, 6, 7, nil], [8, 9, 10, nil]] a.in_groups(3, false) # => [[1, 2, 3, 4], [5, 6, 7], [8, 9, 10]]

• Fix TimeWithZone unmarshaling: coerce unmarshaled Time instances to utc, because Ruby’s marshaling of Time instances doesn’t respect the zone [Geoff Buesing]

• Added Memoizable mixin for caching simple lazy loaded attributes [Josh Peek]

• Move the test related core_ext stuff out of core_ext so it’s only loaded by the test helpers. [Michael Koziarski]

• Add Inflection rules for String#humanize. #535 [Dan Manges]

  ActiveSupport::Inflector.inflections do |inflect|

  inflect.human(/_cnt$/i, '\1_count')

  end

  ‘jargon_cnt’.humanize # => ‘Jargon count’

• TimeWithZone: when crossing DST boundary, treat Durations of days, months or years as variable-length, and all other values as absolute length. A time + 24.hours will advance exactly 24 hours, but a time + 1.day will advance 23-25 hours, depending on the day. Ensure consistent behavior across all advancing methods [Geoff Buesing]

• Added TimeZone #=~, to support matching zones by regex in time_zone_select. #195 [Ernie Miller]

• Added Array#second through Array#fifth as aliases for Array# through Array# + Array#forty_two as alias for Array [David Heinemeier Hansson]

• Fixed Date#end_of_quarter to not blow up on May 31st [#289 state:resolved] (Danger)

*2.1.0 (May 31st, 2008)*

• TimeZone#to_s shows offset as GMT instead of UTC, because GMT will be more familiar to end users (see time zone selects used by Windows OS, google.com and yahoo.com.) Reverts [8370] [Geoff Buesing]

• Hash.from_xml: datetime xml types overflow to Ruby DateTime class when out of range of Time. Adding tests for utc offsets [Geoff Buesing]

• TimeWithZone #+ and #- : ensure overflow to DateTime with Numeric arg [Geoff Buesing]

• Time#to_json: don’t convert to utc before encoding. References #175 [Geoff Buesing]

• Remove unused JSON::RESERVED_WORDS, JSON.valid_identifier? and JSON.reserved_word? methods. Resolves #164. [Cheah Chu Yeow]

• Adding Date.current, which returns Time.zone.today if config.time_zone is set; otherwise returns Date.today [Geoff Buesing]

• TimeWithZone: date part getter methods (year mon day etc) are defined on class; no longer relying on method_missing [Geoff Buesing]

• Time.zone.parse return nil for strings with no date information [Geoff Buesing]

• Time.zone.parse respects offset information in string. Resolves #105. [Scott Fleckenstein, Geoff Buesing]

• Added Ruby 1.8 implementation of Process.daemon

• Duration since and ago with no argument (e.g., 5.days.ago) return TimeWithZone when config.time_zone is set. Introducing Time.current, which returns Time.zone.now if config.time_zone is set, otherwise just returns Time.now [Geoff Buesing]

• Time#since behaves correctly when passed a Duration. Closes #11527 [kemiller]

• Add getutc alias for DateTime#utc [Geoff Buesing]

• Refactor TimeWithZone: don’t send since, ago, #+, #-, advance through method_missing [Geoff Buesing]

• TimeWithZone respects config.active_support.use_standard_json_time_format [Geoff Buesing]

• Modified ActiveSupport::Callbacks::Callback#call to accept multiple arguments.

• Time yesterday and tomorrow behave correctly crossing DST boundary. Closes #7399 [sblackstone]

• TimeWithZone: Adding tests for dst and leap day edge cases when advancing time [Geoff Buesing]

• TimeWithZone#method_missing: send to utc to advance with dst correctness, otherwise send to time. Adding tests for time calculations methods [Geoff Buesing]

• Add config.active_support.use_standard_json_time_format setting so that Times and Dates export to ISO 8601 dates. [Rick Olson]

• TZInfo: Removing unneeded TimezoneProxy class [Geoff Buesing]

• TZInfo: Removing unneeded TimezoneIndexDefinition, since we’re not including Indexes::Timezones [Geoff Buesing]

• Removing unnecessary uses_tzinfo helper from tests, given that TZInfo is now bundled [Geoff Buesing]

• Bundling abbreviated version of TZInfo gem 0.3.8: only the classes and zone definitions required to support Rails time zone features are included. If a recent version of the full TZInfo gem is installed, this will take precedence over the bundled version [Geoff Buesing]

• TimeWithZone#marshal_load does zone lookup via Time.get_zone, so that tzinfo/Olson identifiers are handled [Geoff Buesing]

• Time.zone= accepts TZInfo::Timezone instances and Olson identifiers; wraps result in TimeZone instance [Geoff Buesing]

• TimeWithZone time conversions don’t need to be wrapped in TimeOrDateTime, because TZInfo does this internally [Geoff Buesing]

• TimeWithZone#usec returns 0 instead of error when DateTime is wrapped [Geoff Buesing]

• Improve documentation. [Ryan Bigg, Jan De Poorter, Cheah Chu Yeow, Xavier Shay, Jack Danger Canty, Emilio Tagua, Xavier Noria, Sunny Ripert]

• Ensure that TimeWithZone#to_yaml works when passed a YAML::Emitter. [Rick Olson]

• Ensure correct TimeWithZone#to_date [Geoff Buesing]

• Make TimeWithZone work with tzinfo 0.2.x: use TZInfo::Timezone#zone_identifier alias for abbreviation, silence warnings on tests. Raise LoadError when TZInfo version is < 0.2 by sniffing for TZInfo::TimeOrDateTime constant. Move all tzinfo-dependent TimeZone tests into uses_tzinfo block [Geoff Buesing]

• Time, DateTime and TimeWithZone in_time_zone defaults to Time.zone. Removing now unneeded in_current_time_zone [Geoff Buesing]

• TZInfo caches Timezone instances in its own internal hash cache, so TimeZone::MAPPING doesn’t need to cache them as well [Geoff Buesing]

• Adding TimeZone#parse [Geoff Buesing]

• Adding TimeZone#at and DateTime#to_f [Geoff Buesing]

• TimeWithZone responds to Ruby 1.9 weekday-named query methods [Geoff Buesing]

• TimeWithZone caches TZInfo::TimezonePeriod used for time conversion so that it can be reused, and enforces DST rules correctly when instance is created from a local time [Geoff Buesing]

• Fixed that BufferedLogger should create its own directory if one doesn’t already exist #11285 [lotswholetime]

• Fix Numeric time tests broken by DST change by anchoring them to fixed times instead of Time.now. Anchor TimeZone#now DST test to time specified with Time.at instead of Time.local to work around platform differences with Time.local and DST representation [Geoff Buesing]

• Removing unneeded change_time_zone method from Time, DateTime and TimeWithZone [Geoff Buesing]

• TimeZone local and now correctly enforce DST rules [Geoff Buesing]

• TimeWithZone instances correctly enforce DST rules. Adding TimeZone#period_for_utc [Geoff Buesing]

• test_time_with_datetime_fallback expects DateTime.local_offset instead of DateTime.now.offset [Geoff Buesing]

• Adding TimeWithZone marshal_dump and marshal_load [Geoff Buesing]

• Add OrderedHash#to_hash [Josh Peek]

• Adding Time#end_of_day, _quarter, _week, and _year. #9312 [Juanjo Bazan, Tarmo Tänav, BigTitus]

• Adding TimeWithZone#between? [Geoff Buesing]

• Time.=== returns true for TimeWithZone instances [Geoff Buesing]

• TimeWithZone #+ and #- behave consistently with numeric arguments regardless of whether wrapped time is a Time or DateTime; consistenty answers false to acts_like?(:date) [Geoff Buesing]

• Add String#squish and String#squish! to remove consecutive chunks of whitespace. #11123 [Jordi Bunster, Henrik N]

• Serialize BigDecimals as Floats when using to_yaml. #8746 [Ernesto Jimenez]

• Adding TimeWithZone to_yaml, to_datetime, eql? and method aliases for duck-typing compatibility with Time [Geoff Buesing]

• TimeWithZone in_time_zone returns self if zone argument is the same as time_zone [Geoff Buesing]

• Pruning unneeded TimeWithZone#change_time_zone_to_current [Geoff Buesing]

• Time#zone=, in_time_zone and change_time_zone accept a Duration [Geoff Buesing]

• Time#in_time_zone handles Time.local instances correctly [Geoff Buesing]

• Pruning unneeded Time#change_time_zone_to_current. Enhanced docs to change_time_zone to explain the difference between this method and in_time_zone [Geoff Buesing]

• TimeZone#new method renamed local; when used with Time.zone, constructor now reads: Time.zone.local() [Geoff Buesing]

• Added Base64.encode64s to encode values in base64 without the newlines. This makes the values immediately usable as URL parameters or memcache keys without further processing [David Heinemeier Hansson]

• Remove :nodoc: entries around the ActiveSupport test/unit assertions. #10946 [dancroak, jamesh]

• Add Time.zone_default accessor for setting the default time zone. Rails::Configuration.time_zone sets this. #10982 [Geoff Buesing]

• cache.fetch(key, :force => true) to force a cache miss. [Jeremy Kemper]

• Support retrieving TimeZones with a Duration. TimeZone == TimeZone. [Rick Olson]

• TimeWithZone#- added, so that #- can handle a Time or TimeWithZone argument correctly [Geoff Buesing]

• with_timezone test helper renamed with_env_tz, to distinguish between setting ENV and setting Time.zone in tests [Geoff Buesing]

• Time#- coerces TimeWithZone argument to a Time instance so that difference in seconds can be calculated. Closes #10914 [Geoff Buesing, yyyc514]

• Adding UTC zone to TimeZone; TimeWithZone no longer has to fake UTC zone with nil [Geoff Buesing]

• Time.get_zone refactored to private method, given that the encapsulated logic is only useful internally [Geoff Buesing]

• Time.zone uses thread-local variable for thread safety. Adding Time.use_zone, for overriding Time.zone locally inside a block. Removing unneeded Time.zone_reset! [Geoff Buesing]

• TimeZone#to_s uses UTC rather than GMT; reapplying change that was undone in [8679]. #1689 [Cheah Chu Yeow]

• Time.days_in_month defaults to current year if no year is supplied as argument #10799 [Radar], uses Date.gregorian_leap? to determine leap year, and uses constant lookup to determine days in month [Geoff Buesing]

• Adding Time and DateTime compare_with_coercion, which layers behavior on #<=> so that any combination of Time, DateTime and ActiveSupport::TimeWithZone instances can be chronologically compared [Geoff Buesing]

• TimeZone#now returns an ActiveSupport::TimeWithZone [Geoff Buesing]

• Time in_current_time_zone and change_time_zone_to_current return self when Time.zone is nil [Geoff Buesing]

• Remove unneeded to_datetime_default_s alias for DateTime#to_s, given that we inherit a to_default_s from Date that does exactly the same thing [Geoff Buesing]

• Refactor Time and DateTime to_formatted_s: use ternary instead of nested if/else [Geoff Buesing]

• Adding Time and DateTime formatted_offset, for outputting +HH:MM utc offset strings with cross-platform consistency [Geoff Buesing]

• Adding alternate_utc_string option to TimeZone#formatted_offset. Removing unneeded TimeZone#offset. [Geoff Buesing]

• Introduce ActiveSupport::TimeWithZone, for wrapping Time instances with a TimeZone. Introduce instance methods to Time for creating TimeWithZone instances, and class methods for managing a global time zone. [Geoff Buesing]

• Replace non-dst-aware TimeZone class with dst-aware class from tzinfo_timezone plugin. TimeZone#adjust and unadjust are no longer available; tzinfo gem must now be present in order to perform time zone calculations, via local_to_utc and utc_to_local methods. [Geoff Buesing]

• Extract ActiveSupport::Callbacks from Active Record, test case setup and teardown, and ActionController::Dispatcher. #10727 [Josh Peek]

• Introducing DateTime utc, utc? and utc_offset, for duck-typing compatibility with Time. Closes #10002 [Geoff Buesing]

• Time#to_json uses Numeric#to_utc_offset_s to output a cross-platform-consistent representation without having to convert to DateTime. References #9750 [Geoff Buesing]

• Backport clean_logger changes to support ruby 1.8.2 [Mislav Marohnić]

• Added proper handling of arrays #8537 [Josh Susser]

  Before:

• Added parsing of file type in Hash.xml_in so you can easily do file uploads with base64 from an API [David Heinemeier Hansson]

  <person>
    <name>David</name>
    <avatar type="file" name="me.jpg" content_type="image/jpg">R0lGODlhkACZAPUAAM5lcfjrtMQCG=\n</avatar>

  …becomes:

  attributes = { :person => { :name => "David", :avatar => #<StringIO> } }
  attributes[:person][:avatar].content_type      # => "image/jpg"
  attributes[:person][:avatar].original_filename # => "me.jpg"

  class Email < ActiveRecord::Base
    alias_attribute :subject, :title

  e.subject  # => "Superstars"
  e.subject? # => true
  e.subject = "Megastars"
  e.title    # => "Megastars"

• Deprecation: easier to work with warning behavior as procs; default behaviors for each environment so users needn’t update env.rb; and testing pleasure with assert_deprecated, assert_not_deprecated. [Jeremy Kemper] By default, test prints to $stderr, dev logs, production ignores. Provide your own per-environment in e.g. config/environments/development.rb:

  ActiveSupport::Deprecation.behavior = Proc.new { |message| raise message }

  [1, 2, 3].sum
  payments.sum { |p| p.price * p.tax_rate }
  payments.sum(&:price)

  This is instead of payments.inject(0) { |sum, p| sum + p.price }

• Correct and clarify Array#to_sentence docs. #5458 [brad@madriska.com]

• alias_method_chain preserves method punctuation so foo, foo?, and foo! may be chained with the same feature. [Jeremy Kemper]

  Example:
    alias_method_chain :save!, :validation
  is equivalent to
    alias_method :save_without_validation!, :save!
    alias_method :save!, :save_with_validation!

• Enhance Symbol#to_proc so it works with list objects, such as multi-dimensional arrays. Closes #5295 [nov@yo.rim.or.jp]. Example:

  {1 => "one", 2 => "two", 3 => "three"}.sort_by(&:first).map(&:last)
  # => ["one", "two", "three"]

• Added Hash.create_from_xml(string) which will create a hash from a XML string and even typecast if possible [David Heinemeier Hansson]. Example:

  Hash.create_from_xml <<-EOT
    <note>
      <title>This is a note</title>
      <created-at type="date">2004-10-10</created-at>
    </note>
  EOT

  …would return:

  { :note => { :title => "This is a note", :created_at => Date.new(2004, 10, 10) } }

• Added Jim Weirich’s excellent FlexMock class to vendor (Copyright 2003, 2004 by Jim Weirich (jim@weriichhouse.org)) – it’s not automatically required, though, so require ‘flexmock’ is still necessary [David Heinemeier Hansson]

• Fixed that Module#alias_method_chain should work with both foo? foo! and foo at the same time #4954 [anna@wota.jp]

• to_xml fixes, features, and speedup: introduce :dasherize option that converts updated_at to updated-at if true (the existing default); binary columns get encoding=“base64” attribute; nil values get nil=“true” attribute to distinguish empty values; add type information for float columns; allow arbitrarily deep :include; include SQL type information as the type attribute. #4989 [Blair Zajac <blair@orcaware.com>]

• Add OrderedHash#values. [Sam Stephenson]

• Added Array#to_s(:db) that’ll produce a comma-separated list of ids [David Heinemeier Hansson]. Example:

  Purchase.find(:all, :conditions => "product_id IN (#{shops.products.to_s(:db)})"

• Normalize classify’s argument to a String so that it plays nice with Symbols. [Marcel Molina Jr.]

• Strip out leading schema name in classify. References #5139. [Michael Schoen]

• Remove Enumerable#first_match since break(value) handles the use case well enough. [Nicholas Seckar]

  Enumerable#first_match was like detect, but instead of returning the matching element, the yielded value returned. For example:

  user_xml = adapters(:from => User, :to => Xml).first_match do |adapter|
    adapter.adapt @user
  end

  But this is just as easily done with:

  user_xml = adapters(:from => User, :to => Xml).each do
    break adapter.adapt(@user)
  end

• Make Array#in_groups_of just return the grouped collection if a block isn’t given. [Marcel Molina Jr.]

• Document Module::delegate. #5002 [pergesu@gmail.com]

• Replace alias method chaining with Module#alias_method_chain. [Marcel Molina Jr.]

• Replace Ruby’s deprecated append_features in favor of included. [Marcel Molina Jr.]

• Allow default options in with_options to be overridden. Closes #4480. [murphy@cYcnus.de]

• Update Object.subclasses_of to locate nested classes. This affects Object.remove_subclasses_of in that nested classes will now be unloaded. [Nicholas Seckar]

• Update Object.remove_subclasses_of to use Class.remove_class, reducing duplication. [Nicholas Seckar]

• Added Fixnum#seconds for consistency, so you can say 5.minutes + 30.seconds instead of 5.minutes + 30 #4389 [François Beausoleil]

• Added option to String#camelize to generate lower-cased camel case by passing in :lower, like “super_man”.camelize(:lower) # => “superMan” [David Heinemeier Hansson]

• Added Hash#diff to show the difference between two hashes [Chris McGrath]

• Added Time#advance to do precise time time calculations for cases where a month being approximated to 30 days won’t do #1860 [Rick Olson]

• Enhance Inflector.underscore to convert ‘-’ into ‘_’ (as the inverse of Inflector.dasherize) [Jamis Buck]

• Switched to_xml to use the xml schema format for datetimes. This allows the encoding of time zones and should improve operability. [Michael Koziarski]

• Added a note to the documentation for the Date related Numeric extensions to indicate that they’re

approximations and shouldn’t be used for critical calculations. [Michael Koziarski]

• Added Hash#to_xml and Array#to_xml that makes it much easier to produce XML from basic structures [David Heinemeier Hansson]. Examples:

  { :name => "David", :street_name => "Paulina", :age => 26, :moved_on => Date.new(2005, 11, 15) }.to_xml

  …returns:

  <person>
    <street-name>Paulina</street-name>
    <name>David</name>
    <age type="integer">26</age>
    <moved-on type="date">2005-11-15</moved-on>
  </person>

• Moved Jim Weirich’s wonderful Builder from Action Pack to Active Support (it’s simply too useful to be stuck in AP) [David Heinemeier Hansson]

• Fixed that Array#to_sentence will return “” on an empty array instead of “, and” #3842, #4031 [rubyonrails@beautifulpixel.com]

• Add Enumerable#group_by for grouping collections based on the result of some block. Useful, for example, for grouping records by date.

  ex.

  latest_transcripts.group_by(&:day).each do |day, transcripts|
    p "#{day} -> #{transcripts.map(&:class) * ', '}"
  end
  "2006-03-01 -> Transcript"
  "2006-02-28 -> Transcript"
  "2006-02-27 -> Transcript, Transcript"
  "2006-02-26 -> Transcript, Transcript"

  Add Array#in_groups_of, for iterating over an array in groups of a certain size.

  ex.

  %w(1 2 3 4 5 6 7).in_groups_of(3) {|g| p g}
  ["1", "2", "3"]
  ["4", "5", "6"]
  ["7", nil, nil]

  Marcel Molina Jr., Sam Stephenson

• Added Kernel#daemonize to turn the current process into a daemon that can be killed with a TERM signal [David Heinemeier Hansson]

• Add ‘around’ methods to Logger, to make it easy to log before and after messages for a given block as requested in #3809. [Michael Koziarski] Example:

  logger.around_info(“Start rendering component (#{options.inspect}): ”,

  "\n\nEnd of component rendering") { yield }

• Added Time#beginning_of_quarter #3607 [cohen.jeff@gmail.com]

• Fix Object.subclasses_of to only return currently defined objects [Jonathan Viney <jonathan@bluewire.net.nz>]

• Fix constantize to properly handle names beginning with ‘::’. [Nicholas Seckar]

• Make String#last return the string instead of nil when it is shorter than the limit [Scott Barron].

• Added delegation support to Module that allows multiple delegations at once (unlike Forwardable in the stdlib) [David Heinemeier Hansson]. Example:

  class Account < ActiveRecord::Base
    has_one :subscription
    delegate :free?, :paying?, :to => :subscription
    delegate :overdue?, :to => "subscription.last_payment"
  end
  
  account.free?    # => account.subscription.free?
  account.overdue? # => account.subscription.last_payment.overdue?

• Fix Reloadable to handle the case where a class that has been ‘removed’ has not yet been garbage collected. [Nicholas Seckar]

• Don’t allow Reloadable to be included into Modules.

• Remove LoadingModule. [Nicholas Seckar]

• Add documentation for Reloadable::Subclasses. [Nicholas Seckar]

• Add Reloadable::Subclasses which handles the common case where a base class should not be reloaded, but its subclasses should be. [Nicholas Seckar]

• Further improvements to reloading code [Nicholas Seckar, Trevor Squires]

  • All classes/modules which include Reloadable can define reloadable? for fine grained control of reloading

  • Class.remove_class uses Module#parent to access the parent module

  • Class.remove_class expanded to handle multiple classes in a single call

  • LoadingModule.clear! has been removed as it is no longer required

  • Module#remove_classes_including has been removed in favor of Reloadable.reloadable_classes

• Added reusable reloading support through the inclusion of the Relodable module that all subclasses of ActiveRecord::Base, ActiveRecord::Observer, ActiveController::Base, and ActionMailer::Base automatically gets. This means that these classes will be reloaded by the dispatcher when Dependencies.mechanism = :load. You can make your own models reloadable easily:

  class Setting
    include Reloadable
  end

  Reloading a class is done by removing its constant which will cause it to be loaded again on the next reference. [David Heinemeier Hansson]

• Added auto-loading support for classes in modules, so Conductor::Migration will look for conductor/migration.rb and Conductor::Database::Settings will look for conductor/database/settings.rb [Nicholas Seckar]

• Add Object#instance_exec, like instance_eval but passes its arguments to the block. (Active Support will not override the Ruby 1.9 implementation of this method.) [Sam Stephenson]

• Add Proc#bind(object) for changing a proc or block’s self by returning a Method bound to the given object. Based on why the lucky stiff’s “cloaker” method. [Sam Stephenson]

• Fix merge and dup for hashes with indifferent access #3404 [Ken Miller]

• Fix the requires in option_merger_test to unbreak AS tests. [Sam Stephenson]

• Make HashWithIndifferentAccess#update behave like Hash#update by returning the hash. #3419, #3425 [asnem@student.ethz.ch, JanPrill@blauton.de, Marcel Molina Jr.]

• Add ActiveSupport::JSON and Object#to_json for converting Ruby objects to JSON strings. [Sam Stephenson]

• Add Object#with_options for DRYing up multiple calls to methods having shared options. [Sam Stephenson] Example:

  ActionController::Routing::Routes.draw do |map|

  # Account routes
  map.with_options(:controller => 'account') do |account|
    account.home   '',       :action => 'dashboard'
    account.signup 'signup', :action => 'new'
    account.logout 'logout', :action => 'logout'
  end

  end

• Introduce Dependencies.warnings_on_first_load setting. If true, enables warnings on first load of a require_dependency. Otherwise, loads without warnings. Disabled (set to false) by default. [Jeremy Kemper]

• Active Support is warnings-safe. #1792 [Eric Hodel]

• Introduce enable_warnings counterpart to silence_warnings. Turn warnings on when loading a file for the first time if Dependencies.mechanism == :load. Common mistakes such as redefined methods will print warnings to stderr. [Jeremy Kemper]

• Add Symbol#to_proc, which allows for, e.g. [:foo, :bar].map(&:to_s). [Marcel Molina Jr.]

• Added the following methods [Marcel Molina Jr., Sam Stephenson]:

  • Object#copy_instance_variables_from(object) to copy instance variables from one object to another

  • Object#extended_by to get an instance’s included/extended modules

  • Object#extend_with_included_modules_from(object) to extend an instance with the modules from another instance

• Define kernel.rb methods in “class Object” instead of “module Kernel” to work around a Windows peculiarity [Sam Stephenson]

• Fix broken tests caused by incomplete loading of active support. [Nicholas Seckar]

• Fix status pluralization bug so status_codes doesn’t get pluralized as statuses_code. #2758 [keithm@infused.org]

• Added Kernel#silence_stderr to silence stderr for the duration of the given block [Sam Stephenson]

• Changed Kernel#` to print a message to stderr (like Unix) instead of raising Errno::ENOENT on Win32 [Sam Stephenson]

• Changed 0.blank? to false rather than true since it violates everyone’s expectation of blankness. #2518, #2705 [rails@jeffcole.net]

• When loading classes using const_missing, raise a NameError if and only if the file we tried to load was not present. [Nicholas Seckar]

• Added petabytes and exebytes to numeric extensions #2397 [timct@mac.com]

• Added Time#end_of_month to accompany Time#beginning_of_month #2514 [Jens-Christian Fischer]

1.2.2 (October 26th, 2005)

• Set Logger.silencer = false to disable Logger#silence. Useful for debugging fixtures.

1.2.1 (October 19th, 2005)

• Classify generated routing code as framework code to avoid appearing in application traces. [Nicholas Seckar]

• Show all framework frames in the framework trace. [Nicholas Seckar]

• Fix Logger compatibility for distributions that don’t keep Ruby and its standard library in sync.

• Replace ‘%e’ from long and short time formats as Windows does not support it. #2344. [Tom Ward <tom@popdog.net>]

• Added to_s(:db) to Range, so you can get “BETWEEN ‘2005-12-10’ AND ‘2005-12-12’” from Date.new(2005, 12, 10)..Date.new(2005, 12, 12) (and likewise with Times)

• Moved require_library_or_gem into Kernel. #1992 [Michael Schuerig <michael@schuerig.de>]

• Add :rfc822 as an option for Time#to_s (to get rfc822-formatted times)

• Chain the const_missing hook to any previously existing hook so rails can play nicely with rake

• Clean logger is compatible with both 1.8.2 and 1.8.3 Logger. #2263 [Michael Schuerig <michael@schuerig.de>]

• Added native, faster implementations of .blank? for the core types #2286 [skae]

• Fixed clean logger to work with Ruby 1.8.3 Logger class #2245

• Fixed memory leak with Active Record classes when Dependencies.mechanism = :load #1704 [Chris McGrath]

• Fixed Inflector.underscore for use with acronyms, so HTML becomes html instead of htm_l #2173 [k@v2studio.com]

• Added Kernel#silence_warnings to turn off warnings temporarily for the passed block

• Added String#starts_with? and String#ends_with? #2118 [Thijs van der Vossen]

• Added easy extendability to the inflector through Inflector.inflections (using the Inflector::Inflections singleton class). Examples:

  Inflector.inflections do |inflect|
    inflect.plural /^(ox)$/i, '\1\2en'
    inflect.singular /^(ox)en/i, '\1'
  
    inflect.irregular 'octopus', 'octopi'
  
    inflect.uncountable "equipment"
  end

• Added String#at, String#from, String#to, String#first, String#last in ActiveSupport::CoreExtensions::String::Access to ease access to individual characters and substrings in a string serving basically as human names for range access.

• Make Time#last_month work when invoked on the 31st of a month.

• Add Time.days_in_month, and make Time#next_month work when invoked on the 31st of a month

• Fixed that Time#midnight would have a non-zero usec on some platforms #1836

• Fixed inflections of “index/indices” #1766 [damn_pepe@gmail.com]

• Added Fixnum#ordinalize to turn 1.ordinalize to “1st”, 3.ordinalize to “3rd”, and 10.ordinalize to “10th” and so on #1724 [paul@cnt.org]

1.1.1 (11 July, 2005)

• Added more efficient implementation of the development mode reset of classes #1638 [Chris McGrath]

1.1.0 (6 July, 2005)

• Fixed conflict with Glue gem #1606 [Rick Olson]

• Added new rules to the Inflector to deal with more unusual plurals mouse/louse => mice/lice, information => information, ox => oxen, virus => viri, archive => archives #1571, #1583, #1490, #1599, #1608 [foamdino@gmail.com/others]

• Fixed memory leak with Object#remove_subclasses_of, which inflicted a Rails application running in development mode with a ~20KB leak per request #1289 [Chris McGrath]

• Made 1.year == 365.25.days to account for leap years. This allows you to do User.find(:all, :conditions => [‘birthday > ?’, 50.years.ago]) without losing a lot of days. #1488 [tuxie@dekadance.se]

• Added an exception if calling id on nil to WhinyNil #584 [kevin-temp@writesoon.com]

• Added even? and odd? to work with Bignums in addition to Fixnums #1464 [Thomas Fuchs]

• Fixed Time#at_beginning_of_week returned the next Monday instead of the previous one when called on a Sunday #1403 [jean.helou@gmail.com]

• Increased the speed of indifferent hash access by using Hash#default. #1436 [Nicholas Seckar]

• Added that “ ” is now also blank? (using strip if available)

• Fixed Dependencies so all modules are able to load missing constants #1173 [Nicholas Seckar]

• Fixed the Inflector to underscore strings containing numbers, so Area51Controller becomes area51_controller #1176 [Nicholas Seckar]

• Fixed that HashWithIndifferentAccess stringified all keys including symbols, ints, objects, and arrays #1162 [Nicholas Seckar]

• Fixed Time#last_year to go back in time, not forward #1278 [fabien@odilat.com]

• Fixed the pluralization of analysis to analyses #1295 [seattle@rootimage.msu.edu]

• Fixed that Time.local(2005,12).months_since(1) would raise “ArgumentError: argument out of range” #1311 [jhahn@niveon.com]

• Added silencing to the default Logger class

1.0.4 (19th April, 2005)

• Fixed that in some circumstances controllers outside of modules may have hidden ones inside modules. For example, admin/content might have been hidden by /content. #1075 [Nicholas Seckar]

• Fixed inflection of perspectives and similar words #1045 [Thijs van der Vossen]

• Added Fixnum#even? and Fixnum#odd?

• Fixed problem with classes being required twice. Object#const_missing now uses require_dependency to load files. It used to use require_or_load which would cause models to be loaded twice, which was not good for validations and other class methods #971 [Nicholas Seckar]

1.0.3 (27th March, 2005)

• Fixed Inflector.pluralize to handle capitalized words #932 [Jeremy Kemper]

• Added Object#suppress which allows you to make a saner choice around with exceptions to swallow #980. Example:

  …instead of:

  1/0 rescue nil # BAD, EVIL, DIRTY.

1.0.2 (22th March, 2005)

• Added Kernel#returning – a Ruby-ized realization of the K combinator, courtesy of Mikael Brockman.

  def foo
    returning values = [] do
      values << 'bar'
      values << 'baz'
    end
  end
  
  foo # => ['bar', 'baz']

1.0.1 (7th March, 2005)

• Fixed Hash#indifferent_access to also deal with include? and fetch and nested hashes #726 [Nicholas Seckar]

• Added Object#blank? – see redhanded.hobix.com/inspect/objectBlank.html #783 [_why the lucky stiff]

• Added inflection rules for “sh” words, like “wish” and “fish” #755 [phillip@pjbsoftware.com]

• Fixed an exception when using Ajax based requests from Safari because Safari appends a 000 to the post body. Symbols can’t have 000 in them so indifferent access would throw an exception in the constructor. Indifferent hashes now use strings internally instead. #746 [Tobias Lütke]

• Added String#to_time and String#to_date for wrapping ParseDate

1.0.0 (24th February, 2005)

• Added TimeZone as the first of a number of value objects that among others Active Record can use rich value objects using composed_of #688 [Jamis Buck]

• Added Date::Conversions for getting dates in different convenient string representations and other objects

• Added Time::Conversions for getting times in different convenient string representations and other objects

• Added Time::Calculations to ask for things like Time.now.tomorrow, Time.now.yesterday, Time.now.months_ago(4) #580 [DP|Flurin]. Examples:

  "Later today"         => now.in(3.hours),
  "Tomorrow morning"    => now.tomorrow.change(:hour => 9),
  "Tomorrow afternoon"  => now.tomorrow.change(:hour => 14),
  "In a couple of days" => now.tomorrow.tomorrow.change(:hour => 9),
  "Next monday"         => now.next_week.change(:hour => 9),
  "In a month"          => now.next_month.change(:hour => 9),
  "In 6 months"         => now.months_since(6).change(:hour => 9),
  "In a year"           => now.in(1.year).change(:hour => 9)

• Upgraded to breakpoint 92 which fixes:

  * overload IRB.parse_opts(), fixes #443
    => breakpoints in tests work even when running them via rake
  * untaint handlers, might fix an issue discussed on the Rails ML
  * added verbose mode to breakpoint_client
  * less noise caused by breakpoint_client by default
  * ignored TerminateLineInput exception in signal handler
    => quiet exit on Ctrl-C

• Fixed Inflector for words like “news” and “series” that are the same in plural and singular #603 [echion], #615 [marcenuc]

• Added Hash#stringify_keys and Hash#stringify_keys!

• Added IndifferentAccess as a way to wrap a hash by a symbol-based store that also can be accessed by string keys

• Added Inflector.constantize to turn “Admin::User” into a reference for the constant Admin::User

• Added that Inflector.camelize and Inflector.underscore can deal with modules like turning “Admin::User” into “admin/user” and back

• Added Inflector.humanize to turn attribute names like employee_salary into “Employee salary”. Used by automated error reporting in AR.

• Added availability of class inheritable attributes to the masses #477 [Jeremy Kemper]

  class Foo
    class_inheritable_reader :read_me
    class_inheritable_writer :write_me
    class_inheritable_accessor :read_and_write_me
    class_inheritable_array :read_and_concat_me
    class_inheritable_hash :read_and_update_me
  end
  
  # Bar gets a clone of (not a reference to) Foo's attributes.
  class Bar < Foo
  end
  
  Bar.read_and_write_me == Foo.read_and_write_me
  Bar.read_and_write_me = 'bar'
  Bar.read_and_write_me != Foo.read_and_write_me

• Added Inflections as an extension on String, so Inflector.pluralize(Inflector.classify(name)) becomes name.classify.pluralize #476 [Jeremy Kemper]

• Added Byte operations to Numeric, so 5.5.megabytes + 200.kilobytes #461 [Marcel Molina Jr.]

• Fixed that Dependencies.reload can’t load the same file twice #420 [Kent Sibilev]

• Added Fixnum#ago/until, Fixnum#since/from_now #450 [Jeremy Kemper]

• Added that Inflector now accepts Symbols and Classes by calling .to_s on the word supplied

• Added time unit extensions to Fixnum that’ll return the period in seconds, like 2.days + 4.hours.
