[dependabot]

Bumps sqlalchemy from 2.0.21 to 2.0.26.

Release notes

Sourced from sqlalchemy's releases.

2.0.26

Released: February 11, 2024

orm

• [orm] [bug] Replaced the "loader depth is excessively deep" warning with a shorter message added to the caching badge within SQL logging, for those statements where the ORM disabled the cache due to a too-deep chain of loader options. The condition which this warning highlights is difficult to resolve and is generally just a limitation in the ORM's application of SQL caching. A future feature may include the ability to tune the threshold where caching is disabled, but for now the warning will no longer be a nuisance.

• [orm] [bug] Fixed issue where it was not possible to use a type (such as an enum) within a _orm.Mapped container type if that type were declared locally within the class body. The scope of locals used for the eval now includes that of the class body itself. In addition, the expression within _orm.Mapped may also refer to the class name itself, if used as a string or with future annotations mode.

• [orm] [bug] Fixed issue where using _orm.Session.delete() along with the _orm.Mapper.version_id_col feature would fail to use the correct version identifier in the case that an additional UPDATE were emitted against the target object as a result of the use of _orm.relationship.post_update on the object. The issue is similar to #10800 just fixed in version 2.0.25 for the case of updates alone.

  References: #10967

• [orm] [bug] Fixed issue where an assertion within the implementation for _orm.with_expression() would raise if a SQL expression that was not cacheable were used; this was a 2.0 regression since 1.4.

  References: #10990

examples

• [examples] [bug] Fixed regression in history_meta example where the use of _schema.MetaData.to_metadata() to make a copy of the history table would also copy indexes (which is a good thing), but causing naming conflicts indexes regardless of naming scheme used for those indexes. A "_history" suffix is now added to these indexes in the same way as is
