Commit 4ec5b0d was for fixing the regression #18787, but #28379 fixes
#18787 as well. So 4ec5b0d is no longer necessary.

And prefer `assert_same` over `assert_equal`.

Use whatever adapter-provided means we have available to ensure forked
children don't send quit/shutdown/goodbye messages to the server on
connections that belonged to their parent.

Make `type_map` to private because it is only used in the connection adapter
|
| | |
| | |
| | |
| | |
| | |
| | |
| | | |
`type_map` is an internal API and it is only used in the connection
adapter. And also, some type map initializer methods requires passed
`type_map`, but those instances already has `type_map` in itself.
So we don't need explicit passing `type_map` to the initializers.

If a process is forked more than once, the pool was grabbing the oldest
spec, not the most recent spec. This wasn't noticed before because most
folks are lilely forking the process only once.
If you're forking the process multiple times however the wrong spec name
will be returned and an incorrect connection will be used for the
process.
This fixes the issue by reversing the list of spec names so we can grab
the most recent spec rather than the oldest spec.

The current code base is not uniform. After some discussion,
we have chosen to go with double quotes by default.
|
| |
|
|
|
|
|
| |
Instead of passing a separete name variable, we can make the resolver
merge a name on the config, and use that before creating the Specification.

When calling remove_connection in a subclass, that should not fallback
to the parent, otherwise it will remove the parent connection from the
handler.
|
|
|
|
|
|
|
|

We cannot cache the connection_specification_name when it doesnt
exist. Thats because the parent value could change, and we should keep
failling back to the parent. If we cache that in a children as an ivar,
we would not fallback anymore in the next call, so the children would
not get the new parent spec_name.

remove_connection
When calling `remove_connection` on a model, we delete the pool so we also
need to reset the `connection_specification_name` so it will fallback to
the parent.
This was the current behavior before rails 5, which will fallback to the
parent connection pool.
[fixes #24959]
Special thanks to @jrafanie for working with me on this fix.

ConnectionHandler will not have any knowlodge of AR models now, it will
only know about the specs.
Like that we can decouple the two, and allow the same model to use more
than one connection.
Historically, folks used to create abstract AR classes on the fly in
order to have multiple connections for the same model, and override the
connection methods.
With this, now we can override the `specificiation_id` method in the
model, to return a key, that will be used to find the connection_pool
from the handler.

These new methods are used from the Active Record model layer to
determine which relations are viable to back a model. These new methods
allow us to change `conn.tables` in the future to only return tables and
no views. Same for `conn.table_exists?`.
The goal is to provide the following introspection methods on the
connection:
* `tables`
* `table_exists?`
* `views`
* `view_exists?`
* `data_sources` (views + tables)
* `data_source_exists?` (views + tables)

since NUMBER(8) is not enough to store the maximum number of bigint.
Oracle NUMBER(p,0) as handled as integer
because there is no dedicated integer sql data type exist in Oracle database.
Also NUMBER(p,s) precision can take up to 38. p means the number of digits, not the byte length.
bigint type needs 19 digits as follows.
$ irb
2.2.2 :001 > limit = 8
=> 8
2.2.2 :002 > maxvalue_of_bigint = 1 << ( limit * 8 - 1)

Active Record detects when the process has forked and automatically
creates a new connection pool to avoid sharing file descriptors.
If the existing connection pool had a schema cache associated with it,
the new pool should copy it to avoid unnecessarily querying the database
for its schema.
The code to detect that the process has forked is in ConnectionHandler,
but the existing test for it was in the ConnectionManagement test file.
I moved it to the right place while I was writing the new test for this
change.

This fixes a regression introduced by 6cc03675d30b58e28f585720dad14e947a57ff5b.
ActiveRecord, if used without Rails, always checks the "default_env" environment. This would be OK, except that Sinatra also supports environments,
and it runs with {RACK|RAILS}_ENV=production. This patch adds a fallback to RAILS_ENV and RACK_ENV (and ultimately default_env) if Rails.env doesn't exist.

The MySQLAdapter type map used the lowest priority for enum types.
This was the result of a recent refactoring and lead to some broken lookups
for enums with values that match other types. Like `8bit`.
This patch restores the priority to what we had before the refactoring.

Reliant on https://github.com/rails/rails/pull/15747 but pulled to a
separate PR to reduce noise. `has_many :through` associations have the
undocumented behavior of automatically detecting counter caches.
However, the way in which it does so is inconsistent with counter caches
everywhere else, and doesn't actually work consistently.
As with normal `has_many` associations, the user should specify the
counter cache on the `belongs_to`, if they'd like it updated.
