Redmine

This is related to #19869.

I can store 65535 bytes of text on my installation.

Rails console:

irb(main):001:0> Redmine::VERSION.to_s
=> "3.2.0.stable.15138" 
irb(main):002:0> ActiveRecord::Base.connection.adapter_name
=> "Mysql2" 
irb(main):003:0> Project.find_by_identifier('test').description.size
=> 65535

db/schema.rb:

  create_table "projects", force: :cascade do |t|
    t.string   "name",               limit: 255,   default: "",    null: false
    t.text     "description",        limit: 65535
    t.string   "homepage",           limit: 255,   default: "" 
    t.boolean  "is_public",                        default: true,  null: false
    t.integer  "parent_id",          limit: 4
    t.datetime "created_on" 
    t.datetime "updated_on" 
    t.string   "identifier",         limit: 255
    t.integer  "status",             limit: 4,     default: 1,     null: false
    t.integer  "lft",                limit: 4
    t.integer  "rgt",                limit: 4
    t.boolean  "inherit_members",                  default: false, null: false
    t.integer  "slack",              limit: 4,     default: 0,     null: false
    t.integer  "default_version_id", limit: 4
  end

My old db/schema.rb is:

  create_table "projects", force: :cascade do |t|
    t.string   "name",            limit: 255, default: "",    null: false
    t.text     "description",     limit: 255
    t.string   "homepage",        limit: 255, default: "" 
    t.boolean  "is_public",                   default: true,  null: false
    t.integer  "parent_id" 
    t.datetime "created_on" 
    t.datetime "updated_on" 
    t.string   "identifier",      limit: 255
    t.integer  "status",                      default: 1,     null: false
    t.integer  "lft" 
    t.integer  "rgt" 
    t.boolean  "inherit_members",             default: false, null: false
  end

This environment is version up from very old Redmine step by step.
So I don't know why my db/schema.rb has :limit => 255.
