* Try running pyupgrade on the codeFederico Caselli2022-11-161-58/+58
| | | | | | | | command run is "pyupgrade --py37-plus --keep-runtime-typing --keep-percent-format <files...>" pyupgrade will change assert_ to assertTrue. That was reverted since assertTrue does not exists in sqlalchemy fixtures Change-Id: Ie1ed2675c7b11d893d78e028aad0d1576baebb55
* Send deterministic ordering into unit of work topologicalMike Bayer2020-12-111-3/+1
| | | | | | | | | | | | | | | | Improved the unit of work topological sorting system such that the toplogical sort is now deterministic based on the sorting of the input set, which itself is now sorted at the level of mappers, so that the same inputs of affected mappers should produce the same output every time, among mappers / tables that don't have any dependency on each other. This further reduces the chance of deadlocks as can be observed in a flush that UPDATEs among multiple, unrelated tables such that row locks are generated. topological.sort() has been made "deterministic" in all cases by using a separate list + set. Fixes: #5735 Change-Id: I073103df414dba549e46605b394f8ccae6e80d0e
* Post black reformattingMike Bayer2019-01-061-3/+4
| | | | | | | | | | | | | Applied on top of a pure run of black -l 79 in I7eda77fed3d8e73df84b3651fd6cfcfe858d4dc9, this set of changes resolves all remaining flake8 conditions for those codes we have enabled in setup.cfg. Included are resolutions for all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues.

* Run black -l 79 against all source filesMike Bayer2019-01-061-148/+209
| | | | | | | | | | | | | | This is a straight reformat run using black as is, with no edits applied at all. The black run will format code consistently, however in some cases that are prevalent in SQLAlchemy code it produces too-long lines. The too-long lines will be resolved in the following commit that will resolve all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues.

* start sketching ideas for a rewritten unit of work.Mike Bayer2010-03-191-70/+23
| | | | | | | | | | the basic idea is to bring topological back down to the raw function, then the whole UOW constructs itself as very fine grained elements with full dependencies to each other. then a straight execute with a straight sort. the hope is that the mechanism here would be vastly simpler. while the presence of a large number of fine-grained records may be expensive it still is potentially a lot easier to distill into C code, as the uow's structure now consists of data.
