Upgrade to release 1.4.15:
- A new approach has been applied to the warnings system in
SQLAlchemy to accurately predict the appropriate stack level for
each warning dynamically. This allows evaluating the source of
SQLAlchemy-generated warnings and deprecation warnings to be
more straightforward as the warning will indicate the source
line within end-user code, rather than from an arbitrary level
within SQLAlchemy’s own source code.
orm:
- Fixed additional regression caused by “eager loaders run on
unexpire” feature #1763 where the feature would run for a
contains_eager() eagerload option in the case that the
contains_eager() were chained to an additional eager loader
option, which would then produce an incorrect query as the
original query-bound join criteria were no longer present.
- Fixed issue in subquery loader strategy which prevented caching
from working correctly. This would have been seen in the logs as
a “generated” message instead of “cached” for all subqueryload
SQL emitted, which by saturating the cache with new keys would
degrade overall performance; it also would produce “LRU size
alert” warnings.
sql:
- Adjusted the logic added as part of #6397 in 1.4.12 so that
internal mutation of the BindParameter object occurs within the
clause construction phase as it did before, rather than in the
compilation phase. In the latter case, the mutation still
produced side effects against the incoming construct and
additionally could potentially interfere with other internal
mutation routines.
mysql:
- Added support for the ssl_check_hostname= parameter in mysql
connection URIs and updated the mysql dialect documentation
regarding secure connections. Original pull request courtesy of
Jerry Zhao.
