As was pointed out by #17128, our blacklist of mutation methods was
non-exhaustive (and would need to be kept up to date with each new
version of Ruby). Now that `Relation` includes `Enumerable`, the number
of methods that we actually need to delegate are pretty small. As such,
we can change to explicitly delegating the few non-mutation related
methods that `Array` has which aren't on `Enumerable`

This reverts commit 8246b593bff71f2cebf274c133bb8917f1e094c8.
There was concern about this modifying the behavior of past migrations.
We're going to add an way to modify the migration generator instead.

It's often the case that you want to have an option that you cannot
specify at the database level, but want applied to *all* tables that you
create. For example, you might want to specify `ROW_FORMAT=DYNAMIC` to
not have to limit text columns to length 171 for indexing when using
utf8mb4. This allows an easy way to specify this in your database
configuration.
While this change affects both MySQL and MySQL2, the test only covers
MySQL2, as the legacy mysql adapter appears to always return ASCII
strings, and is tangential to what we're actually doing.

- key was a poor choice of name. A key implies something that will
unlock a lock. The concept is actually more like a 'lock identifier'
- mysql documentation calls this a 'lock name'
- postgres documentation calls it a 'lock_id'
- Updated variable names to reflect the preferred terminology for the database in
question

In b71e08f we started raising when nil or false was passed to merge to
fix #12264, however we should also do this for truthy values that are
invalid like true.

Make `AR::SpawnMethods#merge!` to check an arg is a Proc

From Ruby ( 2.3.0dev trunk 52520), `Hash#to_proc` is defined
(https://github.com/ruby/ruby/commit/fbe967ec02cb65a7efa3fb8f3d747cf6f620dde1),
and many tests have been failed with
`ArgumentError: wrong number of arguments (given 0, expected 1)`.
Because we call `Hash#to_proc` with no args in `#merge!`.
This commit changes order of conditionals to not call `Hash#to_proc`.

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.

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?`.

Skipping `marked_for_destruction?` when the associated object does not responds
to it make easier to validate virtual associations built on top of Active Model
objects and/or serialized objects that implement a `valid?` instance method.

The previous commit changes the state of the class, and while we are
cleaning up the database, I forgot to clean up the class

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.

Make migrations concurrent safe (using advisory locks)

- Addresses issue #22092
- Works on Postgres and MySQL
- Uses advisory locks because of two important properties:
1. 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.

This assumes only one query was ever executed, but it appears to
sometimes be loading schema information. We can just look at the array
of queries, rather than the "first" one that was run

added ActiveRecord::Relation#outer_joins
|
| | |
| | |
| | |
| | |
| | |
| | | |
Example:
User.left_outer_joins(:posts)
=> SELECT "users".* FROM "users" LEFT OUTER JOIN "posts" ON "posts"."user_id" = "users"."id"
|
| | |

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.

Support SQL sanitization in AR::QueryMethods#order
|
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | | |
Add support for sanitizing arrays in SQL ORDER clauses.
This is useful when using MySQL `ORDER BY FIELD()` to return records in
a predetermined way.
```ruby
Tag.order(['field(id, ?', [1,3,2]].to_sql
# => SELECT "tags".* FROM "tags" ORDER BY field(id, 1,3,2)
```
Prior to this, developers must be careful to sanitize `#order` arguments
themselves.
|
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | | |
This is part of a refactoring to make it easier to allow `order` to use
sanitize like just about everything else on relation. The deleted test
doesn't give any reasoning as to why passing `nil` to `order` needs to
be supported, and it's rather nonsensical. I can almost see allowing an
empty string being passed (though I'm tempted to just disallow it...)

default value for FixtureSet.fixture_class_names ought to be a Class

Look at `TestFixtures.set_fixture_class`. As documented, it
accepts a mapping of fixture identifiers (string or symbol) to Classes
(the model classes that implement the named fixture).
Look now at the initialization of `TestFixtures.fixture_class_names`.
It defines a Hash, which will return a string by default (where the
string is the estimated class name of the given fixture identifier).
Now look at TestFixtures.load_fixtures. It calls `FixtureSet.create_fixtures`,
passing in the mapping of `fixture_class_names`.
Following this on to `FixtureSet.create_fixtures`, this instantiates a
`FixtureSet::ClassCache`, passing in the map of class names.
`ClassCache`, in turn, calls `insert_class` for each value in the cache.
(Recall that `set_fixture_class` puts Class objects in there, while the
default proc for the mapping puts String objects.)
Look finally at `insert_class`. If the value is present, it checks to
see if the value is a subclass of `AR::Base`. Fair enough...but wait!
What if the value is a String? You get an exception, because a String
instance cannot be compared with a Class.
Judging from the implementation, it seems like the expected behavior
here is for `fixture_class_names` to have no default proc. Look-ups are
supposed to happen via `ClassCache`, with `fixture_class_names` existing
solely as a repository for explicitly-registered class mappings.
That is what this change does.
