Changes In Branch sorter-reference Excluding Merge-Ins
This is equivalent to a diff from 0ab45188 to 413015c0
2018-04-18
| ||
19:56 | Add the "sorter-reference" optimization, allowing SQLite to be configured so that some required values may be loaded from the database after external sorting occurs for SELECT statements with ORDER BY clauses that are not satisfied by database indexes. (check-in: ef74090a user: dan tags: trunk) | |
19:08 | Avoid a NULL-pointer deref following OOM. (Closed-Leaf check-in: 413015c0 user: drh tags: sorter-reference) | |
15:21 | Add the --sorterref N option to the CLI. (check-in: 902a4089 user: drh tags: sorter-reference) | |
2018-04-16
| ||
10:34 | Reduce the size of the NameContext object by grouping seldom-used fields into a union. (check-in: dba3095f user: drh tags: trunk) | |
2018-04-14
| ||
18:46 | Experimental change to "SELECT * FROM ... ORDER BY" processing to load some column values from the db after sorting. (check-in: 9719cb46 user: dan tags: sorter-reference) | |
2018-04-13
| ||
16:29 | Merge the preupdate hook change from trunk. (check-in: 7353caab user: drh tags: upsert) | |
16:23 | Remove an always-true branch from the preupdate hook logic. (check-in: 0ab45188 user: drh tags: trunk) | |
2018-04-11
| ||
17:10 | Help the parser run faster by avoiding the "explain ::= ." production. (check-in: d7ec7b59 user: drh tags: trunk) | |
