* | | | | | | | Don't cache `find_by` statements on STI subclassesRyuta Kamizono2019-02-273-5/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Caching `find_by` statements on STI subclasses is unsafe, since `type IN (?,?,?,?)` part is dynamic, and we don't have SQL statements cache invalidation when a STI subclass is created or removed for now.

This is a regression caused by cbcdecd. If query caching is enabled, prepared statement handles are never re-used, since we missed that a query is preprocessed when query caching is enabled, but doesn't keep the `preparable` flag. We should care about that case.

This seems to have been fixed with SQLite 3.20.0(https://sqlite.org/changes.html#version_3_20_0). But CI uses the old version(maybe 3.11.0), I added `DISTINCT` to avoid optimization by subquery flattening. Ref: https://sqlite.org/optoverview.html#flattening

* | | | | | | | Fix `pluck` and `select` with `from` if `from` has original table nameRyuta Kamizono2019-02-222-1/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is caused by 0ee96d1. Since #18744, `select` columns doesn't be qualified by table name if using `from`. 0ee96d1 follows that for `pluck` as well. But people depends that `pluck` columns are qualified even if using `from`. So I've fixed that to be qualified if `from` has the original table name to keep the behavior as much as before. Fixes #35359.

It should not be passed extra args, should only be passed attribute names.

One of the overloads is the capability to accept a regular expression and then run a match, then return the receiver (if it matched) or one of the groups from the MatchData. The function of the `UUID#cast` method is to cast a UUID to a type and format acceptable by postgres. Naturally UUIDs are supposed to be string and of a certain format, but it had been determined that it was not ideal for the framework to send just any old string to Postgres and allow the engine to complain when "foobar" or "" was sent, being obviously of the wrong format for a valid UUID. Therefore this code was written to facilitate the checking, and if it were not of the correct format, a `nil` would be returned as is conventional in Rails. Now, the subscript method will allocate one or more strings on a match and return one of them, based on the index parameter. However, there is no need for a new string, as a UUID of the correct format is already such, and so long as the format was verified then the string supplied is adequate for consumption by the database. The subscript method also creates a MatchData object which will never be used, and so must eventually be garbage collected. Garbage collection indeed. This innocuous method tends to be called quite a lot, for example if the primary key of a table is a uuid, then this method will be called. If the foreign key of a relation is a UUID, once again this method is called. If that foreign key is belonging to a has_many relationship with dozens of objects, then again dozens of UUIDs shall be cast to a dup of themselves, and spawn dozens of MatchData objects, and so on. So, for users that: * Use UUIDs as primary keys * Use Postgres * Operate on collections of objects This accomplishes a significant savings in total allocations, and may save many garbage collections.
