[CVE-2020-8165] Deprecate Marshal.load on raw cache read in RedisCacheStore
[CVE-2020-8165] Avoid Marshal.load on raw cache value in MemCacheStore
Make ActiveSupport::Logger Fiber-safe. Fixes #36752.
Use Fiber.current.__id__ in ActiveSupport::Logger#local_level= in order
to make log level local to Ruby Fibers in addition to Threads.
Example:
logger = ActiveSupport::Logger.new(STDOUT)
logger.level = 1
p "Main is debug? #{logger.debug?}"
Fiber.new {
logger.local_level = 0
p "Thread is debug? #{logger.debug?}"
}.resume
p "Main is debug? #{logger.debug?}"
Before:
Main is debug? false
Thread is debug? true
Main is debug? true
After:
Main is debug? false
Thread is debug? true
Main is debug? false
Alexander Varnin
Add ActiveSupport::HashWithIndifferentAccess#assoc.
assoc can now be called with either a string or a symbol.
Stefan Schüßler
Fix String#safe_constantize throwing a LoadError for incorrectly cased constant references.
Keenan Brock
Allow Range#=== and Range#cover? on Range
Range#cover? can now accept a range argument like Range#include? and
Range#===. Range#=== works correctly on Ruby 2.6. Range#include? is moved
into a new file, with these two methods.
utilum
If the same block is included multiple times for a Concern, an exception is no longer raised.
Mark J. Titorenko, Vlad Bokov
Fix bug where #to_options for ActiveSupport::HashWithIndifferentAccess
would not act as alias for #symbolize_keys.
Nick Weiland
Improve the logic that detects non-autoloaded constants.
Jan Habermann, Xavier Noria
Fix bug where URI.unescape would fail with mixed Unicode/escaped character input:
URI.unescape("\xe3\x83\x90") # => "バ"
URI.unescape("%E3%83%90") # => "バ"
URI.unescape("\xe3\x83\x90%E3%83%90") # => Encoding::CompatibilityError
Ashe Connor, Aaron Patterson
Redis cache store: delete_matched no longer blocks the Redis server.
(Switches from evaled Lua to a batched SCAN + DEL loop.)
Gleb Mazovetskiy
Fix bug where ActiveSupport::Timezone.all would fail when tzinfo data for
any timezone defined in ActiveSupport::TimeZone::MAPPING is missing.
Dominik Sander
Fix bug where ActiveSupport::Cache will massively inflate the storage
size when compression is enabled (which is true by default). This patch
does not attempt to repair existing data: please manually flush the cache
to clear out the problematic entries.
Godfrey Chan
Fix ActiveSupport::Cache#read_multi bug with local cache enabled that was
returning instances of ActiveSupport::Cache::Entry instead of the raw values.
Jason Lee
Caching: MemCache and Redis read_multi and fetch_multi speedup.
Read from the local in-memory cache before consulting the backend.
Gabriel Sobrinho
Return all mappings for a timezone identifier in country_zones.
Some timezones like Europe/London have multiple mappings in
ActiveSupport::TimeZone::MAPPING so return all of them instead
of the first one found by using Hash#value. e.g:
# Before
ActiveSupport::TimeZone.country_zones("GB") # => ["Edinburgh"]
# After
ActiveSupport::TimeZone.country_zones("GB") # => ["Edinburgh", "London"]
Fixes #31668.
Andrew White
Add support for connection pooling on RedisCacheStore.
fatkodima
Support hash as first argument in assert_difference. This allows to specify multiple
numeric differences in the same assertion.
assert_difference ->{ Article.count } => 1, ->{ Post.count } => 2
Julien Meichelbeck
Add missing instrumentation for read_multi in ActiveSupport::Cache::Store.
Ignatius Reza Lesmana
assert_changes will always assert that the expression changes,
regardless of from: and to: argument combinations.
Daniel Ma
Use SHA-1 to generate non-sensitive digests, such as the ETag header.
Enabled by default for new apps; upgrading apps can opt in by setting
config.active_support.use_sha1_digests = true.
Dmitri Dolguikh, Eugene Kenny
Changed default behaviour of ActiveSupport::SecurityUtils.secure_compare,
to make it not leak length information even for variable length string.
Renamed old ActiveSupport::SecurityUtils.secure_compare to fixed_length_secure_compare,
and started raising ArgumentError in case of length mismatch of passed strings.
Vipul A M
Make ActiveSupport::TimeZone.all return only time zones that are in
ActiveSupport::TimeZone::MAPPING.
Fixes #7245.
Chris LaRose
MemCacheStore: Support expiring counters.
Pass expires_in: [seconds] to #increment and #decrement options
to set the Memcached TTL (time-to-live) if the counter doesn't exist.
If the counter exists, Memcached doesn't extend its expiry when it's
incremented or decremented.
Rails.cache.increment("my_counter", 1, expires_in: 2.minutes)
Takumasa Ochi
Handle TZInfo::AmbiguousTime errors.
Make ActiveSupport::TimeWithZone match Ruby's handling of ambiguous
times by choosing the later period, e.g.
Ruby:
ENV["TZ"] = "Europe/Moscow"
Time.local(2014, 10, 26, 1, 0, 0) # => 2014-10-26 01:00:00 +0300
Before:
>> "2014-10-26 01:00:00".in_time_zone("Moscow")
TZInfo::AmbiguousTime: 26/10/2014 01:00 is an ambiguous local time.
After:
>> "2014-10-26 01:00:00".in_time_zone("Moscow")
=> Sun, 26 Oct 2014 01:00:00 MSK +03:00
Fixes #17395.

redis: -> { Redis.new … }
Deployment note: Take care to use a dedicated Redis cache rather than pointing this at your existing Redis server. It won't cope well with mixed usage patterns and it won't expire cache entries by default.

Cache: Enable compression by default for values > 1kB.
Compression has long been available, but opt-in and at a 16kB threshold. It wasn't enabled by default due to CPU cost. Today it's cheap and typical cache data is eminently compressible, such as HTML or JSON fragments. Compression dramatically reduces Memcached/Redis mem usage, which means the same cache servers can store more data, which means higher hit rates.
To disable compression, pass compress: false to the initializer.
Jeremy Daer
Allow Range#include? on TWZ ranges.
In #11474 we prevented TWZ ranges being iterated over which matched
Ruby's handling of Time ranges and as a consequence include?
stopped working with both Time ranges and TWZ ranges. However in
ruby/ruby@b061634 support was added for include? to use cover?
for 'linear' objects. Since we have no way of making Ruby consider
TWZ instances as 'linear' we have to override Range#include?.
Fixes #30799.
Andrew White
Fix acronym support in humanize.
Acronym inflections are stored with lowercase keys in the hash but
the match wasn't being lowercased before being looked up in the hash.
This shouldn't have any performance impact because before it would
fail to find the acronym and perform the downcase operation anyway.
Fixes #31052.
Andrew White
Add same method signature for Time#prev_year and Time#next_year
in accordance with Date#prev_year, Date#next_year.
Allows pass argument for Time#prev_year and Time#next_year.

IO#to_json now returns the to_s representation, rather than
attempting to convert to an array. This fixes a bug where IO#to_json
would raise an IOError when called on an unreadable object.
Fixes #26132.
Paul Kuruvilla
Remove deprecated halt_callback_chains_on_return_false option.
Rafael Mendonça França
Remove deprecated :if and :unless string filter for callbacks.
Rafael Mendonça França
Hash#slice now falls back to Ruby 2.5+'s built-in definition if defined.
Akira Matsuda
Deprecate secrets.secret_token.
The architecture for secrets had a big upgrade between Rails 3 and Rails 4,
when the default changed from using secret_token to secret_key_base.
secret_token has been soft deprecated in documentation for four years
but is still in place to support apps created before Rails 4.
Deprecation warnings have been added to help developers upgrade their
applications to secret_key_base.
claudiob, Kasper Timm Hansen
Return an instance of HashWithIndifferentAccess from HashWithIndifferentAccess#transform_keys.
Yuji Yaginuma
Add key rotation support to MessageEncryptor and MessageVerifier.
This change introduces a rotate method to both the MessageEncryptor and
MessageVerifier classes. This method accepts the same arguments and
options as the given classes' constructor. The encrypt_and_verify method
for MessageEncryptor and the verified method for MessageVerifier also
accept an optional keyword argument :on_rotation block which is called
when a rotated instance is used to decrypt or verify the message.
Michael J Coyne
Deprecate Module#reachable? method.
bogdanvlviv
Add config/credentials.yml.enc to store production app secrets.
Allows saving any authentication credentials for third party services
directly in repo encrypted with config/master.key or ENV["RAILS_MASTER_KEY"].
This will eventually replace Rails.application.secrets and the encrypted
secrets introduced in Rails 5.1.
DHH, Kasper Timm Hansen
Add ActiveSupport::EncryptedFile and ActiveSupport::EncryptedConfiguration.
Allows for stashing encrypted files or configuration directly in repo by encrypting it with a key.
Backs the new credentials setup above, but can also be used independently.
DHH, Kasper Timm Hansen
Module#delegate_missing_to now raises DelegationError if target is nil,
similar to Module#delegate.
Anton Khamets
Update String#camelize to provide feedback when wrong option is passed.
String#camelize was returning nil without any feedback when an
invalid option was passed as a parameter.
Previously:
'one_two'.camelize(true)
# => nil
Now:
'one_two'.camelize(true)
# => ArgumentError: Invalid option, use either :upper or :lower.
Ricardo Díaz
Fix modulo operations involving durations.
Rails 5.1 introduced ActiveSupport::Duration::Scalar as a wrapper
around numeric values as a way of ensuring a duration was the outcome of
an expression. However, the implementation was missing support for modulo
operations. This support has now been added and should result in a duration
being returned from expressions involving modulo operations.
Prior to Rails 5.1:
5.minutes % 2.minutes
# => 60
Now:
5.minutes % 2.minutes
# => 1 minute
Fixes #29603 and #29743.
Sayan Chakraborty, Andrew White
Fix division where a duration is the denominator.
PR #29163 introduced a change in behavior when a duration was the denominator
in a calculation - this was incorrect as dividing by a duration should always
return a Numeric. The behavior of previous versions of Rails has been restored.
Fixes #29592.
Andrew White
Add purpose and expiry support to ActiveSupport::MessageVerifier and
ActiveSupport::MessageEncryptor.
For instance, to ensure a message is only usable for one intended purpose:
token = @verifier.generate("x", purpose: :shipping)
@verifier.verified(token, purpose: :shipping) # => "x"
@verifier.verified(token) # => nil
Or make it expire after a set time:
@verifier.generate("x", expires_in: 1.month)
@verifier.generate("y", expires_at: Time.now.end_of_year)
Showcased with ActiveSupport::MessageVerifier, but works the same for
ActiveSupport::MessageEncryptor's encrypt_and_sign and decrypt_and_verify.
Pull requests: #29599, #29854

Make the order of Hash#reverse_merge! consistent with HashWithIndifferentAccess.
Erol Fornoles
Add freeze_time helper which freezes time to Time.now in tests.
Prathamesh Sonpatki
Default ActiveSupport::MessageEncryptor to use AES 256 GCM encryption.
On for new Rails 5.2 apps. Upgrading apps can find the config as a new framework default.

Cache: write_multi.
Rails.cache.write_multi foo: 'bar', baz: 'qux'
Plus faster fetch_multi with stores that implement write_multi_entries.
Keys that aren't found may be written to the cache store in one shot
instead of separate writes.
The default implementation simply calls write_entry for each entry.
Stores may override if they're capable of one-shot bulk writes, like
Redis MSET.
Jeremy Daer
Add default option to module and class attribute accessors.
mattr_accessor :settings, default: {}
Works for mattr_reader, mattr_writer, cattr_accessor, cattr_reader,
and cattr_writer as well.
Genadi Samokovarov
Add Date#prev_occurring and Date#next_occurring to return specified next/previous occurring day of week.
Shota Iguchi
Add default option to class_attribute.
Before:
class_attribute :settings
self.settings = {}
Now:
class_attribute :settings, default: {}
DHH
#singularize and #pluralize now respect uncountables for the specified locale.
Eilis Hamilton
Add ActiveSupport::CurrentAttributes to provide a thread-isolated attributes singleton.
Primary use case is keeping all the per-request attributes easily available to the whole system.
DHH
Fix implicit coercion calculations with scalars and durations.
Previously, calculations where the scalar is first would be converted to a duration of seconds, but this causes issues with dates being converted to times, e.g:
Time.zone = "Beijing" # => Asia/Shanghai
date = Date.civil(2017, 5, 20) # => Mon, 20 May 2017
2 * 1.day # => 172800 seconds
date + 2 * 1.day # => Mon, 22 May 2017 00:00:00 CST +08:00
Now, the ActiveSupport::Duration::Scalar calculation methods will try to maintain
the part structure of the duration where possible, e.g:
Time.zone = "Beijing" # => Asia/Shanghai
date = Date.civil(2017, 5, 20) # => Mon, 20 May 2017
2 * 1.day # => 2 days
date + 2 * 1.day # => Mon, 22 May 2017
Fixes #29160, #28970.
Andrew White
Add support for versioned cache entries. This enables the cache stores to recycle cache keys, greatly saving
on storage in cases with frequent churn. Works together with the separation of #cache_key and #cache_version
in Active Record and its use in Action Pack's fragment caching.
DHH
Pass gem name and deprecation horizon to deprecation notifications.
Willem van Bergen
Add support for :offset and :zone to ActiveSupport::TimeWithZone#change.
Andrew White
Add support for :offset to Time#change.
Fixes #28723.
Andrew White
Add fetch_values for HashWithIndifferentAccess.
The method was originally added to Hash in Ruby 2.3.0.
