| | | | | | | | | | | | | | | | | | :attr:`.Query.column_descriptions`. This refers to the primary ORM mapped class or aliased class that is referred to by the expression. Compared to the existing entry for ``"type"``, it will always be a mapped entity, even if extracted from a column expression, or None if the given expression is a pure core expression. references #3320

| | | | | | | | | | | | | | | | | | | | | | | | DROP TYPE instruction when a plain ``table.drop()`` is called, assuming the object is not associated directly with a :class:`.MetaData` object. In order to accomodate the use case of an enumerated type shared between multiple tables, the type should be associated directly with the :class:`.MetaData` object; in this case the type will only be created at the metadata level, or if created directly. The rules for create/drop of Postgresql enumerated types have been highly reworked in general. fixes #3319
| * - Added a new event suite :class:`.QueryEvents`. TheMike Bayer2015-03-105-7/+125
| | | | | | | | | | | | | | | | | | | | | | :meth:`.QueryEvents.before_compile` event allows the creation of functions which may place additional modifications to :class:`.Query` objects before the construction of the SELECT statement. It is hoped that this event be made much more useful via the advent of a new inspection system that will allow for detailed modifications to be made against :class:`.Query` objects in an automated fashion. fixes #3317

This will produce more efficient queries in these cases. fixes #3249

| | * | Partial index support with sqlite dialects.Kai Groner2015-01-261-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From https://www.sqlite.org/partialindex.html > Partial indexes have been supported in SQLite since version 3.8.0. Reflection does not expose the predicate of partial indexes. The postgresql dialect does detect such indexes and issue a warning. I looked into matching this level of support, but the sqlite pragma index_info does not expose the predicate. Getting this data would probably require parsing the CREATE INDEX statement from sqlite_master.

| * | | - fix a potential race condition where the per-mapper LRUCache used byMike Bayer2015-03-091-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | persistence.py could theoretically hit the limit of the cache (100 items by default) and at some points fail to have a key that we check for, due to the cleanup. This has never been observed so its likely that so far, the total number of INSERT, UPDATE and DELETE statement structures in real apps has not exceeded 100 on a per-mapper basis; this could happen for apps that run a very wide variety of attribute modified combinations into the unit of work, *and* which have very high concurrency going on. This change will be a lot more significant when we open up use of LRUCache + compiled cache with the baked query extension.

| * | | - the change for #918 was of course not nearly that simple.Mike Bayer2015-03-076-42/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "wrapping" employed by the mssql and oracle dialects using the "iswrapper" argument was not being used intelligently by the compiler, and the result map was being written incorrectly, using *more* columns in the result map than were actually returned by the statement, due to "row number" columns that are inside the subquery. The compiler now writes out result map on the "top level" select in all cases fully, and for the mssql/oracle wrapping case extracts out the "proxied" columns in a second step, which only includes those columns that are proxied outwards to the top level. This change might have implications for 3rd party dialects that might be imitating oracle's approach. They can safely continue to use the "iswrapper" kw which is now ignored, but they may need to also add the _select_wraps argument as well.
| * | | - do a full rewrite of callcountsMike Bayer2015-03-071-94/+93

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | such that they are matched to the received result set positionally, rather than by name. Originally, this was seen as a way to handle cases where we had columns returned with difficult-to-predict names, though in modern use that issue has been overcome by anonymous labeling. In this version, the approach basically reduces function call count per-result by a few dozen calls, or more for larger sets of result columns. The approach still degrades into a modern version of the old approach if textual elements modify the result map, or if any discrepancy in size exists between the compiled set of columns versus what was received, so there's no issue for partially or fully textual compilation scenarios where these lists might not line up. fixes #918 - callcounts still need to be adjusted down for this so zoomark tests won't pass at the moment

| | | | | | | | | | | | | | | | | | | | | | | | | For versions > 1.10.1 pg8000 returns de-serialized JSON objects rather than a string. SQL parameters are still strings though.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pg8000 uses Versioneer, which means that development versions have version strings that don't fit into the dotted triple number format. Released versions will always fit the triple format though.

The work of create_row_processor() for ColumnProperty objects is essentially done at query setup time combined with some lookups in _instance_processor(). - to allow this change for deferred columns, deferred columns no longer search for themselves in the result. If they've been set up as deferred without any explicit directive to undefer them, then this is what was asked for. if we don't do this, then we're stuck with this performance penalty for all deferred columns which in the vast majority of typical use cases (e.g. loading large, legacy tables or tables with many/large very seldom used values) won't be present in the result and won't be accessed at all.
