2019-01-17
| ||
| 15:40 | Revamp the SrcList allocator routines to be methods of Parse instead of being methods of the "sqlite3" object, so that they can leave better error messages when the SrcList object grows too large. file: [d08c9e01] check-in: [df08d472] user: drh branch: trunk, size: 37309 | |
|
2018-12-29
| ||
| 02:26 | A new implementation of sqlite3VdbeMakeLabel() is faster and makes fewer memory allocations by deferring memory allocation until sqlite3VdbeResolveLabel() is called, at which point the code generator has a better idea of how big the relocation table needs to be. The sqlite3VdbeMakeLabel() routine now takes a Parse* parameter instead of Vdbe*. file: [209cd834] check-in: [4a0929ac] user: drh branch: trunk, size: 37305 | |

2018-11-07

| 16:46 | Performance improvement in subroutine that decides whether or not a table is read-only. file: [cec65c0e] check-in: [6e4968b0] user: drh branch: read-only-shadow, size: 37251 | |
|
2018-11-06
| ||
| 19:26 | Enable DEFENSIVE mode by default for tests. This requires lots of case of turning DEFENSIVE off in order to dodgy things to the database for testing purposes. No all of those cases are yet handled, so "make test" does not run to completion. file: [36825ff2] check-in: [a1d6c671] user: drh branch: read-only-shadow, size: 37121 | |
| 15:57 | Turn on defensive mode for running test scripts. Does not yet work. file: [d058ed72] check-in: [1c1d24ed] user: drh branch: read-only-shadow, size: 37097 | |
| 14:03 | Only allow shadow table to be written from within a recursive SQL call. Omit the SQLITE_PREPARE_SHADOW flag. Some tests are failing because the tests depend on being able to write to shadow tables. file: [5217cecc] check-in: [d890c658] user: drh branch: read-only-shadow, size: 37073 | |
| 13:37 | Add enforcement of read-only on shadow tables. This does not currently work since some virtual tables are attempting to update shadow tables using sqlite3_exec(). file: [51c469c1] check-in: [f79b47c9] user: drh branch: read-only-shadow, size: 36971 | |

| 21:35 | In the Expr object, the Expr.eX field determines what value is stored in the Expr.x union. This mostly works, but there are issues identified by valgrind. file: [07a7ecf1] check-in: [8849a463] user: drh branch: expr-simplify, size: 36780 | |
|
2018-08-04

| 15:53 | Further logic simplifications that flow out of the omission of the column cache. file: [107e28d3] check-in: [7d9072b0] user: drh branch: omit-column-cache, size: 36812 | |
|
2018-08-03
| ||
| 23:04 | Completely remove the column cache logic, which has been a persistent source of bugs for many years. Due to recent enhancements to the performance of the OP_Column opcode, removing the column cache actually makes speed-check.sh run faster. Removing the column cache also saves about 1,800 bytes of code space. file: [3838d883] check-in: [3f5f60cd] user: drh branch: omit-column-cache, size: 36873 | |
|
2018-05-24
| ||
| 23:51 | When doing a one-pass UPDATE or DELETE on virtual tables, close the cursor prior to running VUpdate. This allows one-pass to work on virtual tables that do not allow concurrent reads and writes. Enhance rtree to take advantage of this new capability. file: [4c8c7604] check-in: [b816023c] user: drh branch: trunk, size: 36942 | |

2018-04-20

|
2018-04-19
| ||

|
2018-01-12
| ||
| 16:44 | Experimental change to include changes made to the sqlite_stat1 table in changesets generated by the sessions module. sqlite_stat1 entries in such changesets are ignored by legacy clients. file: [20c87884] check-in: [bd46c442] user: dan branch: sessions-stat1, size: 36817 | |
| 00:30 | Enable the one-pass optimization for DELETE and UPDATE on RTree. This is parked in a branch because is seems to make no measureable performance difference. file: [f0f08da5] check-in: [8b8314cb] user: drh branch: rtree-one-pass, size: 36875 | |
|
2017-12-08

|
2017-11-14
| ||
| 23:48 | In the parse tree, combine LIMIT and OFFSET into a single expression rooted on a TK_LIMIT node, for a small code size reduction and performance increase, and a reduction in code complexity. file: [e6a70fb5] check-in: [3925facd] user: drh branch: trunk, size: 36766 | |
| 18:26 | Fix the SQLITE_ENABLE_UPDATE_DELETE_LIMIT functionality so that it works with views and WITHOUT ROWID tables. This is a modified cherrypick of [dae4a97a]. file: [7a9df721] check-in: [b2679d3b] user: dan branch: branch-3.8.9, size: 33893 | |

| 14:26 | Critical fix to the previous check-in so that it works when there are BEFORE triggers that move the cursor before the OP_Delete has a chance to be applied. file: [4220f4fe] check-in: [db2c0960] user: drh branch: trunk, size: 35094 | |
