# This file eases your Rails 7.1 framework defaults upgrade.
#
# Uncomment each configuration one by one to switch to the new default.
# Once your application is ready to run with all new defaults, you can remove
# this file and set the `config.load_defaults` to `7.1`.
#
# Read the Guide for Upgrading Ruby on Rails for more info on each option.

# No longer add autoloaded paths into `$LOAD_PATH`. This means that you won't be able
# to manually require files that are managed by the autoloader, which you shouldn't do anyway.
# This will reduce the size of the load path, making `require` faster if you don't use bootsnap, or reduce the size
# of the bootsnap cache if you use it.
Rails.application.config.add_autoload_paths_to_load_path = false

# Remove the default X-Download-Options headers since it is used only by Internet Explorer.

# Active Record Encryption now uses SHA-256 as its hash digest algorithm. Important: If you have
# data encrypted with previous Rails versions, there are two scenarios to consider:
#
# 1. If you have +config.active_support.key_generator_hash_digest_class+ configured as SHA1 (the default
# before Rails 7.0), you need to configure SHA-1 for Active Record Encryption too:
# Rails.application.config.active_record.encryption.hash_digest_class = OpenSSL::Digest::SHA1
# 2. If you have +config.active_support.key_generator_hash_digest_class+ configured as SHA256 (the new default
# in 7.0), then you need to configure SHA-256 for Active Record Encryption:
# Rails.application.config.active_record.encryption.hash_digest_class = OpenSSL::Digest::SHA256
#
# If you don't currently have data encrypted with Active Record encryption, you can disable this setting to
# configure the default behavior starting 7.1+:

# No longer run after_commit callbacks on the first of multiple Active Record
# instances to save changes to the same database row within a transaction.
# Instead, run these callbacks on the instance most likely to have internal
# state which matches what was committed to the database, typically the last
# instance to save.

# Configures SQLite with a strict strings mode, which disables double-quoted string literals.
#
# SQLite has some quirks around double-quoted string literals.
# It first tries to consider double-quoted strings as identifier names, but if they don't exist
# it then considers them as string literals. Because of this, typos can silently go unnoticed.
# For example, it is possible to create an index for a non existing column.
# See https://www.sqlite.org/quirks.html#double_quoted_string_literals_are_accepted for more details.

# Enable the Active Job `BigDecimal` argument serializer, which guarantees
# roundtripping. Without this serializer, some queue adapters may serialize
# `BigDecimal` arguments as simple (non-roundtrippable) strings.
#
# When deploying an application with multiple replicas, old (pre-Rails 7.1)
# replicas will not be able to deserialize `BigDecimal` arguments from this
# serializer. Therefore, this setting should only be enabled after all replicas
# have been successfully upgraded to Rails 7.1.
Rails.application.config.active_job.use_big_decimal_serializer = true

# Specify if an `ArgumentError` should be raised if `Rails.cache` `fetch` or
# `write` are given an invalid `expires_at` or `expires_in` time.

# as `handled` and logged instead.

# Specify whether Query Logs will format tags using the SQLCommenter format
# (https://open-telemetry.github.io/opentelemetry-sqlcommenter/), or using the legacy format.
# Options are `:legacy` and `:sqlcommenter`.
Rails.application.config.active_record.query_log_tags_format = :sqlcommenter

# Specify the default serializer used by `MessageEncryptor` and `MessageVerifier`
# instances.
#
# The legacy default is `:marshal`, which is a potential vector for
# deserialization attacks in cases where a message signing secret has been
# leaked.
#
# In Rails 7.1, the new default is `:json_allow_marshal` which serializes and
# deserializes with `ActiveSupport::JSON`, but can fall back to deserializing
# with `Marshal` so that legacy messages can still be read.
#
# In Rails 7.2, the default will become `:json` which serializes and
# deserializes with `ActiveSupport::JSON` only.
#
# Alternatively, you can choose `:message_pack` or `:message_pack_allow_marshal`,
# which serialize with `ActiveSupport::MessagePack`. `ActiveSupport::MessagePack`
# can roundtrip some Ruby types that are not supported by JSON, and may provide
# improved performance, but it requires the `msgpack` gem.

# together. This changes the message format, so messages serialized this way
# cannot be read by older versions of Rails. However, messages that use the old
# format can still be read, regardless of whether this optimization is enabled.
#
# To perform a rolling deploy of a Rails 7.1 upgrade, wherein servers that have
# not yet been upgraded must be able to read messages from upgraded servers,
# leave this optimization off on the first deploy, then enable it on a
