In order to avoid using `send` in such a case, changed methods to public.

But I'd like to keep that combined because it would help inverting polymorphic predicates correctly (e9ba12f7), and we can collect equality nodes regardless of combined by `Arel::Nodes::And` (`a AND (b AND c) AND d` == `a AND b AND c AND d`). This change fixes the regression to collect equality nodes in `Arel::Nodes::And` as well. Fixes #31338.

While attempting to copy the table, the type of the primary key was ignored. Once that was corrected, copying the indexes would fail because custom primary keys are autoindexed by sqlite by default. To correct that, this skips copying the index if the index name begins with "sqlite_". This is a reserved word that indicates that the index is an internal schema object. SQLite prohibits applications from creating objects whose names begin with "sqlite_", so this string should be safe to use as a check. ref https://www.sqlite.org/fileformat2.html#intschema

SQLite3 integer is stored in 1, 2, 3, 4, 6, or 8 bytes depending on the magnitude of the value. Assuming default valid value as 4 bytes caused that actual valid value in INTEGER storage class cannot be stored and existing value cannot be found. https://www.sqlite.org/datatype3.html We should allow valid value in INTEGER storage class in SQLite3 to fix the regression. Fixes #22594.

The previous behavior should not be changed. Fixes #31301.

There are certain attributes which we want to always consider initialized. Previously, they were handled separately. The primary key (which is assumed to be backed by a database column) needs to be initialized, because there is a ton of code in Active Record that assumes `foo.id` will never raise. Additionally, we want attributes which aren't backed by a database column to always be initialized, since we would never receive a database value for them. Ultimately these two concerns can be combined into one. The old implementation hid a lot of inherent complexity, and is hard to optimize from the outside. We can simplify things significantly by just passing in a hash. This has slightly different semantics from the old behavior, in that `Foo.select(:bar).first.id` will return the default value for the primary key, rather than `nil` unconditionally -- however, the default value is always `nil` in practice.

In MySQL, errno 1317 (`ER_QUERY_INTERRUPTED`) is only used when the query is manually cancelled. But in PostgreSQL, `QUERY_CANCELED` error code (57014) which is used `StatementTimeout` is also used when the both case. And, we can not tell which reason happened. So I decided to introduce new error class `QueryCanceled` closer to the error code name.
* | | | | | | | | Rename `TransactionTimeout` to more descriptive `LockWaitTimeout` (#31223)Ryuta Kamizono2017-11-273-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since #31129, new error class `StatementTimeout` has been added. `TransactionTimeout` is caused by the timeout shorter than `StatementTimeout`, but its name is too generic. I think that it should be a name that understands the difference with `StatementTimeout`.
