Use 6.0 version of ActiveRecord::Migration for Action Mailbox Since Action Mailbox will be introduced in Rails 6.0, it makes more sense to generate migration of that version. Also I changed its test dummy app to use default 6.0 configs. 2018-12-30 09:04:17 +08:00			`class CreateActionMailboxTables < ActiveRecord::Migration[6.0]`

Ensure Action Mailbox processes an email only once when received multiple times This also adds a new column, message_checksum, to the action_mailbox_inbound_emails table for storing SHA1 digest of the email source. Additionally, it makes generating the missing message id deterministic and adds a unique index on message_checksum and message_id to detect duplicate emails. 2019-01-18 01:13:40 +08:00			`t.string :message_id, null: false`

Allow changing text and blob size without giving the `limit` option In MySQL, the text column size is 65,535 bytes by default (1 GiB in PostgreSQL). It is sometimes too short when people want to use a text column, so they sometimes change the text size to mediumtext (16 MiB) or longtext (4 GiB) by giving the `limit` option. Unlike MySQL, PostgreSQL doesn't allow the `limit` option for a text column (raises ERROR: type modifier is not allowed for type "text"). So `limit: 4294967295` (longtext) couldn't be used in Action Text. I've allowed changing text and blob size without giving the `limit` option, it prevents that migration failure on PostgreSQL. 2019-01-25 21:01:07 +08:00			`t.timestamps`

Specify a name for [ message_id, message_checksum ] index to ensure the name does not exceed the limit. Also, update test schema to reflect the recent changes. 2019-01-18 04:14:45 +08:00			`t.index [ :message_id, :message_checksum ], name: "index_action_mailbox_inbound_emails_uniqueness", unique: true`
