* If an index can't be found by column, use the index name.Ezekiel Smithburg2013-03-071-0/+6
| | | | schema_statements uses the column name by default to construct the index name, and then raises an exception if it doesn't exist, even if the name option is specified, which causes #8858. this commit makes index_name_for_remove fall back to constructing the index name to remove based on the name option.

* `Connection#structure_dump` is no longer used. #9518Yves Senn2013-03-061-5/+0
| | | | | | | As of ccc6910c we use `mysqldump` to create the `structure.sql`. The old `#structure_dump` code is still in AR but never used. I removed all relevant parts from the code-base.
* Support PostgreSQL specific column types when using `change_table`.Yves Senn2013-02-281-4/+8
| | | | | | | | Closes #9480. We use `TableDefinition` for `#create_table` and `Table` for `#change_table`. The PostgreSQL sepcifc types were only defined on `TableDefinition` so I also added them to `Table`.
* update docs, change_table does not use TableDefinition.Yves Senn2013-02-281-3/+3

* | Add more documentation for create_join_table.Marc Schütz2013-02-201-0/+8
| | | | | | | | | | Explain that it doesn't create indices by default and that it also has a block form.
* | also rename indexes when a table or column is renamedYves Senn2013-02-201-0/+22
| | | | | | | | When a table or a column is renamed related indexes kept their name. This will lead to confusing names. This patch renames related indexes when a column or a table is renamed. Only indexes with names generated by rails will be renamed. Indexes with custom names will not be renamed.
* | reserve index name chars for internal rails operationsYves Senn2013-02-202-3/+14
| | | | | | | | | | | | | | | | | | | | | | Some adapter (SQLite3) need to perform renaming operations to support the rails DDL. These rename prefixes operate with prefixes. When an index name already uses up the full space provieded by `index_name_length` these internal operations will fail. This patch introduces `allowed_index_name_length` which respects the amount of characters used for internal operations. It will always be <= `index_name_length` and every adapter can define how many characters need to be reserved.
* | Reduced memory leak problem in transactions by lazily updating AR objects ↵wangjohn2013-02-201-3/+10
| | | | | | | | with new transaction state. If AR object has a callback, the callback will be performed immediately (non-lazily) so the transaction still has to keep records with callbacks.

* | Fix cases where delete_records on a has_many association caused errorsDerek Kraan2013-01-271-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | because of an ambiguous column name. This happened if the association model had a default scope that referenced a third table, and the third table also referenced the original table (with an identical foreign_key). Mysql requires that ambiguous columns are deambiguated by using the full table.column syntax. Postgresql and Sqlite use a different syntax for updates altogether (and don't tolerate table.name syntax), so the fix requires always including the full table.column and discarding it later for Sqlite and Postgresql.

The original @controllers cache no longer makes much sense after @tenderlove's changes in 7b6bfe84f3 and f345e2380c. * Use TS::Cache in the connection pool to avoid locking overhead. * Use TS::Cache in ConnectionHandler.
