| * Except keys of `build_record`'s argument from `create_scope` in ↵yui-knk2015-11-165-5/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | initialize_attributes If argument of `build_record` has key and value which is same as default value of database, we should also except the key from `create_scope` in `initialize_attributes`. Because at first `build_record` initialize record object with argument of `build_record`, then assign attributes derived from Association's scope. In this case `record.changed` does not include the key, which value is same as default value of database, so we should add the key to except list. Fix #21893.

* / Freeze association foreign keys to reduce allocationsSean Griffin2015-11-151-1/+1
|/ | | | | | | | | | | | The string returned here will ultimately get used as a key of a hash in the attribute set once the attributes are being built. When you give a non-frozen string to `Hash#[]`, it will be duped. Be freezing we can significantly reduce the number of times we end up allocating `"user_id"` This does not include any additional tests, as this should not have any public facing implications. If you are mutating the result of `Reflection#foreign_key`, please stop.
* Deprecate `#table_exists?`, `#tables` and passing arguments to `#talbes`yui-knk2015-11-0924-98/+208
| | | | | | | | | | Reported on #21509, how views is treated by `#tables` are differ by each adapters. To fix this different behavior, after Rails 5.0 is released, deprecate `#tables`. And `#table_exists?` would check both tables and views. To make their behavior consistent with `#tables`, after Rails 5.0 is released, deprecate `#table_exists?`.

* Ensure `#reset_column_information` clears child classes as wellSean Griffin2015-11-073-0/+28
| | | | | | | | | | | | | | I've added a redundant test for this under the attributes API as well, as that also causes this bug to manifest through public API (and demonstrates that calling `reset_column_information` on the child classes would be insufficient) Since children of a class should always share a table with their parent, just reloading the schema from the cache should be sufficient here. `reload_schema_from_cache` should probably become public and `# :nodoc:`, but I'd rather avoid the git churn here. Fixes #22057

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit f6ca7e4e75408bc42f515fc7206d6c6ff0dce7c6. The default collation of utf8 in MySQL is the `utf8_general_ci`, and this should not be changed. This is because, the better collation in the all locales is not exists, optimal collation in own application is not known other than themselves. The `utf8_unicode_ci` is known as Japanese killer in Japan, there are serious impacts in search of Japanese. MySQL implements the `utf8_unicode_ci` according to the Unicode Collation Algorithm (UCA) described at http://www.unicode.org/reports/tr10/, but the `utf8_unicode_ci` have only partial support for the UCA, only primary level key comparison implemented (also known as L1 (Base characters) comparison). Because L1 (Base characters) comparison does not distinguish between the presence or absence of the accent, if distinction of the accent is important there is a serious impact (e.g. Japanese). Example: ``` > SHOW CREATE TABLE `dicts`\G *************************** 1. row *************************** Table: dicts Create Table: CREATE TABLE `dicts` ( `word` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL, `meaning` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci 1 row in set (0.00 sec) > INSERT INTO `dicts` VALUES ('ハハ', 'mother'), ('パパ', 'father'); Query OK, 2 rows affected (0.00 sec) > SELECT * FROM `dicts` WHERE `word` = 'ハハ'; +--------+---------+ | word | meaning | +--------+---------+ | ハハ | mother | | パパ | father | +--------+---------+ 2 rows in set (0.00 sec) > CREATE UNIQUE INDEX `unique_index_word` ON `dicts`(`word`); ERROR 1062 (23000): Duplicate entry 'ハハ' for key 'unique_index_word' ``` We should omit the collation entirely rather than providing a default. Then the choice is the responsibility of the server and MySQL distribution.

The can be obtained outside of the context of a transaction 2. They are automatically released when the session ends, so if a migration process crashed for whatever reason the lock is not left open perpetually - Adds get_advisory_lock and release_advisory_lock methods to database adapters - Attempting to run a migration while another one is in process will raise a ConcurrentMigrationError instead of attempting to run in parallel with undefined behavior. This could be rescued and the migration could exit cleanly instead. Perhaps as a configuration option? Technical Notes ============== The Migrator uses generate_migrator_advisory_lock_key to build the key for the lock. In order to be compatible across multiple adapters there are some constraints on this key. - Postgres limits us to 64 bit signed integers - MySQL advisory locks are server-wide so we have to scope to the database - To fulfil these requirements we use a Migrator salt (a randomly chosen signed integer with max length of 31 bits) that identifies the Rails migration process as the owner of the lock. We multiply this salt with a CRC32 unsigned integer hash of the database name to get a signed 64 bit integer that can also be converted to a string to act as a lock key in MySQL databases. - It is important for subsequent versions of the Migrator to use the same salt, otherwise different versions of the Migrator will not see each other's locks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, if `ActiveRecord::Base.belongs_to_required_by_default` is set to `true`, then creating a record through `has_and_belongs_to_many` fails with the cryptic error message `Left side must exist`. This is because `inverse_of` isn't working properly in this case, presumably since we're doing trickery with anonymous classes in the middle. Rather than following this rabbit hole to try and get `inverse_of` to work in a case that we know is not publicly supported, we can just turn off this validation to match the behavior of 4.2 and earlier.
