inheriting mappers to be GC'ed when the
class itself is deferenced. The mapper
must not have its own table (i.e.
single table inh only) without polymorphic
attributes in place.
This allows for the use case of
creating a temporary subclass of a declarative
mapped class, with no table or mapping
directives of its own, to be garbage collected
when dereferenced by a unit test.
[ticket:2526]
This directory contains informal scripts used to stress test various library subsections over the years, including testing of memory usage, function call count, threading behavior. The scripts here are *not* part of the automated test suite, and instead were used at the time of development for particular features or performance enhancements in an ad-hoc fashion. Ideally the various functionality tested within would be brought under the umbrella of controlled, automated tests. Many of the scripts here are out of date and are possibly covered by formal performance tests elsewhere. Current automated stress and performance tests are in test/aaa_profiling/, which test either for expected function call count, or flat growth in memory usage over time. These tests are part of the automated test suite and are maintained for 100% success rate along Python versions from 2.4 through current 3 versions.
