Fixes #18106
|
|
|
|
|
|
| |
We should document current behavior, and this is design of API for now.
Closes #17597

The implementation of the generation of the foreign key name was changed
between Rails 4.2.0 and 4.2.1 from a random to a deterministic behavior,
however the documentation still describes the old randomized behavior.

It behaves in the same way that the abstract adapter.

https://github.com/ruby/ruby/pull/579 - there is a new optimization
since ruby 2.2
Previously regexp patterns were faster (since a string was converted to
regexp underneath anyway). But now string patterns are faster and
better reflect the purpose.
Benchmark.ips do |bm|
bm.report('regexp') { 'this is ::a random string'.gsub(/::/, '/') }
bm.report('string') { 'this is ::a random string'.gsub('::', '/') }
bm.compare!
end
# string: 753724.4 i/s
# regexp: 501443.1 i/s - 1.50x slower

This reverts commit a38732c8e6ab76ea0db4e1a617a1fa84b53a9750.
Since the mutation logic was reverted in
07278519bb6db5579171fea70bccdfee1306f1d4, we must bring the reader
method back as well, since the implementation relies on it.

We don't want the records to hold hard references to transactions
because they point at records that have callbacks.
|
| | |
|
| |
| |
| |
| |
| | |
this lets us keep singleton instances of "state" values and precalculate
return values of things like `finalized?` and `completed?`.
|
| |
| |
| |
| |
| | |
this way we don't have to mutate a state object, we can just change the
state of the txn

As far as I can tell nobody is setting this variable.

We do this in the adapter classes specifically, so the types aren't
registered if we don't use that adapter. Constants under the PostgreSQL
namespace for example are never loaded if we're using mysql.

Refactor `quote_default_expression`

`quote_default_expression` and `quote_default_value` are almost the same
handling for do not quote default function of `:uuid` columns. Rename
`quote_default_value` to `quote_default_expression`, and remove
duplicate code.

MySQL rejects to remove an index which is used in a foreign key constraint:
```
ActiveRecord::StatementInvalid: Mysql2::Error: Cannot drop index 'index_copies_on_title_id': needed in a foreign key constraint: ALTER TABLE `copies` DROP `title_id`
```
Removing the constraint before removing the column (and the index) solves this problem.

The keys are already validated, so it is better to use the built-in
feature to do this.

The various databases don't actually need significantly different
handling for this behavior, and they can achieve it without knowing
about the type of the object.
The old implementation was returning a string, which will cause problems
such as breaking TZ aware attributes, and making it impossible for the
adapters to supply their logic for time objects.
|
| |
| |
| |
| |
| |
| | |
`sql_type` is reused in `lookup_cast_type`. If making it a part of
`sql_type` when handled array option first, it isn't necessary to do
again.

The same is not true of `define_attribute`, which is meant to be the low
level no-magic API that sits underneath. The differences between the two
APIs are:
- `attribute`
- Lazy (the attribute will be defined after the schema has loaded)
- Allows either a type object or a symbol
- `define_attribute`
- Runs immediately (might get trampled by schema loading)
- Requires a type object
This was the last blocker in terms of public interface requirements
originally discussed for this feature back in May. All the
implementation blockers have been cleared, so this feature is probably
ready for release (pending one more look-over by me).
