Backport of dd1fa3a31b4680c0d3712e6ae122b878138580c7 from main [4.0.x] Fixed #33141 -- Renamed Expression.empty_aggregate_value to empty_result_set_value. 2021-09-29T18:52:59Z David Wobrock david.wobrock@gmail.com 2021-09-24T20:05:02Z urn:sha1:aab76433ed585ebe997b94547e0d790605e01ad9 Backport of ad36a198a12df4dff65992191b3eb0a474e2daac from main Refs #27624 -- Optimized Query.clone() for non-combined queries. 2021-09-20T10:34:18Z Keryn Knight keryn@kerynknight.com 2021-09-16T10:03:04Z urn:sha1:5353e7c2505c0d0ab8232ad9c131b3c99c833988 This avoids constructing a generator expression and a new tuple if the Query has no combined queries. Refs #27624 -- Changed Query.explain_info to namedtuple. 2021-09-17T05:15:12Z Adam Johnson me@adamj.eu 2021-09-14T17:08:19Z urn:sha1:fc91ea1e50e5ef207f0f291b3f6c1942b10db7c7 Optimized Query.clone() a bit. 2021-09-17T05:12:56Z Adam Johnson me@adamj.eu 2021-09-17T05:08:55Z urn:sha1:2931d847c246b6f499993e370f6d9a53a83120d2 This removes unnecessary "if ... is None" branches, which are already shallow-copied in the __dict__.copy() call. Fixed #33073 -- Fixed queryset crash with aggregation and empty/extra queryset annotation. 2021-09-01T18:59:16Z David Wobrock david.wobrock@gmail.com 2021-08-31T20:37:07Z urn:sha1:691486a5cf7588c95250a873c5b57748e82fc4c2 Fixed #33025 -- Avoided accessing the database connections in Query.build_lookup() when not necessary. 2021-08-19T11:28:59Z Keryn Knight keryn@kerynknight.com 2021-08-14T14:30:54Z urn:sha1:bf5abf1bdcedb15e949db419c61eeec7c88414ea Of the built-in backends, only Oracle treats empty strings and nulls as equal, so avoid testing the default connection backend for interprets_empty_strings_as_nulls if it can be established from the lookup that it wouldn't affect the lookup instance returned. This improves performance a small amount for most lookups being built, because accessing the connections requires touching the thread critical `Local` which is an expensive operation. Refs #32946 -- Changed Query.add_filter() to take two arguments. 2021-07-28T07:38:42Z Keryn Knight keryn@kerynknight.com 2021-07-17T20:54:36Z urn:sha1:5b8ef8aa5b746d96d6558efd6bc119f347002703 Fixed #32951 -- Removed Query.where_class & co. 2021-07-22T06:49:20Z Nick Pope nick@nickpope.me.uk 2021-07-20T19:38:17Z urn:sha1:c35b81b864ffa84751bac7d73046840f576491f9 Unused since 3caf957ed5eaa831a485abcb89f27266dbf3e82b. Fixed #32704 -- Fixed list of deferred fields when chaining QuerySet.defer() after only(). 2021-07-20T10:15:29Z David Wobrock david.wobrock@gmail.com 2021-07-19T21:02:52Z urn:sha1:fd999318ad78613227cdb7c5656345d9e216802b
