| 19:44 | Put NEVER() on a branch in STAT4 that appears to be unreachable. (Closed-Leaf check-in: 0ca35e92 user: drh tags: mistake) | |
| 15:32 | Add in a VdbeCoverage() macro needed by STAT4 that should have been part of check-in [63ef234e88857a65]. (check-in: d51c699a user: drh tags: trunk) | |
| 01:12 | Always convert 32-bit integer literals into EP_IntValue notation, even if they contain "_" separators. (check-in: 2dfc427f user: drh tags: trunk) | |
|
2024-02-27
| ||
| 20:19 | Fix an eputf() macro without its argument in the CLI. (check-in: c2f5e257 user: drh tags: trunk) | |
| 19:57 | Add an assert() to help scan-build recognize that a variable is initialized. (check-in: 10d26f1e user: drh tags: trunk) | |
| 16:39 | • Edit [0d9a25962c180a4e|0d9a2596]: Mark "Closed". (artifact: 9f5e8da6 user: drh) | |
| 16:39 | • Edit [8c788fc4b2ff21e4|8c788fc4]: Move to branch wrong-branch. Mark "Closed". (artifact: 13eb9de1 user: drh) | |
| 16:36 | Adjust a VdbeCoverage() macro in PRAGMA integrity_check to account for the fact that arguments to the OP_Eq opcode used are never NULL. (check-in: 759ccea3 user: drh tags: trunk) | |
| 16:36 | • Edit [0d9a25962c180a4e|0d9a2596]: Move to branch mistake. Edit check-in comment. (artifact: 902370e0 user: drh) | |

| 15:56 |
| |
| 15:33 | Remove unreachable branches from the PRAGMA integrity_check enhancement of [b736519d3d2e93c7]. (check-in: 6d02fb23 user: drh tags: trunk) | |
|
2024-02-26
| ||
| 22:28 | The quote() SQL function should convert +Inf into 9.0e+999 and -Inf into -9.0e+999. See forum post 6675b25108. (check-in: 85dd79a6 user: drh tags: trunk) | |
| 15:27 | When inserting a 3-byte cell into a btree, ensure that the extra padding byte is 0x00. This is not necessary for security, as far as I can tell, but it seems like a reasonable precaution. (check-in: 5766f127 user: drh tags: trunk) | |
| 11:51 | Fix header comments on test scripts. (Closed-Leaf check-in: 9fe9670c user: drh tags: incr-integrity-check) | |
| 11:43 | Remove a local variable from sqlite3IntFloatCompare() that was being optimized out anyhow, in order to get back to 100% MC/DC. (check-in: 52b13d6a user: drh tags: trunk) | |
|
2024-02-25
| ||
| 21:30 | Make sure key comprisons are done correctly if the index key contains NaN values that have not been shifted into NULLs. That can only happen due to database corruption, but we need to deal with it nevertheless. (check-in: 7e4c743f user: drh tags: trunk) | |
|
2024-02-24
| ||
| 19:58 | Add two GIFs that contain the feather logo. (check-in: 5f21e6a8 user: drh tags: trunk) | |
|
2024-02-22
| ||
| 00:50 | Fix debugging code so that it compiles on MSVC. (check-in: ce5df19d user: drh tags: trunk) | |
|
2024-02-21
| ||
| 20:21 | Fix typo in comment. Fossil forum post cc20266bf2. (check-in: 7e3c46ee user: drh tags: trunk) | |
|
2024-02-20
| ||
| 15:38 | Fixes to comments associated with the recent PRAGMA optimize enhancements. No changes to code. (check-in: 27a2113d user: drh tags: trunk) | |
| 13:11 | Remove an unreachable branch from printf(). Change it into an assert(). (check-in: 4c9886b6 user: drh tags: trunk) | |
| 13:10 | Remove an unused variable from the merge in the previous check-in. (check-in: 5c26bf37 user: drh tags: trunk) | |
| 12:48 | Enhancements to PRAGMA optimize and ANALYZE. Add the 0x10000 flag to PRAGMA optimize. ANALYZE now records zero-size partial indexes in the sqlite_stat1 table. PRAGMA optimize looks for both growth and shrinkage in table sizes, and uses tighter bounds (10x rather than 25x) to trigger a re-analyze. PRAGMA optimize automatically uses are reasonable analysis_limit to prevent excessive runtimes. (check-in: 63ef234e user: drh tags: trunk) | |
| 12:14 | Another simplification of the PRAGMA optimize logic for improved coverage. (Closed-Leaf check-in: 6c5a0c85 user: drh tags: better-pragma-optimize) | |
|
2024-02-19
| ||
| 23:58 | Minor fixes. (check-in: ed5afebc user: drh tags: better-pragma-optimize) | |
| 20:47 | Fix a minor hiccup in the computation of the number of btrees to be scanned. (check-in: 91302d9b user: drh tags: better-pragma-optimize) | |
| 20:12 | If there is no mention of a table in sqlite_stat1, use OP_Rewind to see if the table is empty prior to invoking ANALYZE. (check-in: 0cc93b19 user: drh tags: better-pragma-optimize) | |
| 19:56 | In PRAGMA optimize, scale back the analysis_limit when many different tables and indexes must be scanned. (check-in: 63661535 user: drh tags: better-pragma-optimize) | |
| 18:57 | • Edit [2cf78a5b5fce7f2d|2cf78a5b]: Edit check-in comment. (artifact: ea748af2 user: drh) | |
| 18:57 | • Edit [40532ffba91cf332|40532ffb]: Move to branch better-pragma-optimize. (artifact: 09c8e3a0 user: drh) | |
| 18:55 | Merge trunk fixes into the better-pragma-optimize branch. (check-in: 2cf78a5b user: drh tags: better-pragma-optimize) | |
| 18:55 | • Edit [40532ffba91cf332|40532ffb]: Move to branch better-optimize. (artifact: 4d0599e1 user: drh) | |
| 16:22 | If a table has one or more rows and it has a partial index has zero rows, still make an entry in the sqlite_stat1 table for the partial index, so that we know that "PRAGMA optimize" does not need to redo the whole table. (check-in: e147b189 user: drh tags: better-pragma-optimize) | |
| 13:50 | Simplifications to PRAGMA optimize to make it easier to use. It always tries to ANALYZE unanalyzed indexes. The 0x10000 flag just makes it check for size changes in all tables. (check-in: 44ed7f4c user: drh tags: better-pragma-optimize) | |
| 13:06 | Change the 0x20000 bit (use analysis limit) to 0x10, meaning that this feature is on by default. The default analysis limit is changed to 2000 which is almost always sufficient for accurate analysis results. (check-in: 4abd47b5 user: drh tags: better-pragma-optimize) | |
|
2024-02-18
| ||
| 01:12 | Hold a transaction during PRAGMA optimize, for performance. (check-in: d13b79ea user: drh tags: better-pragma-optimize) | |
|
2024-02-17
| ||
| 16:39 | Add new MASK bits to PRAGMA optimize: 0x70000. (check-in: dd449706 user: drh tags: better-pragma-optimize) | |
| 03:36 | Fix rounding in zero-precision %f and %g printf conversions. (check-in: 1ebea57f user: drh tags: branch-3.45) | |
| 03:32 | Fix rounding in zero-precision %f and %g printf conversions. Forum post 393708f4a8. This bug was introduced by check-in [32befb224b254639] and first appeared in version 3.43.0. (check-in: 7fca1bc4 user: drh tags: trunk) | |
| 01:12 | The PRAGMA optimize command invokes ANALYZE if a table shrinks by 25 times in addition to if it grows by 25 times. (check-in: 40532ffb user: drh tags: better-pragma-optimize) | |
|
2024-02-16
| ||
| 21:34 | Fix the subtype on the value column from json_each/json_tree for cases when the value is an array or object. (check-in: b278ae39 user: drh tags: branch-3.45) | |
| 21:30 | Fix the subtype on the value column from json_each/json_tree for cases when the value is an array or object. Fix for the bug reported by forum post ecb94cd210. (check-in: 1c33c5db user: drh tags: trunk) | |
| 12:57 | Rename the TF_StatsUsed flag to TF_MaybeReanalyze, to more accurately reflect its usage. No logic changes. (check-in: b4790da5 user: drh tags: trunk) | |
|
2024-02-13
| ||
| 18:44 | Fix a bug in PRAGMA integrity_check introduced by enhancement (8a) in release 3.42.0. (check-in: 60dccb23 user: drh tags: branch-3.45) | |
| 18:41 | Fix a bug in PRAGMA integrity_check introduced by enhancement (8a) in release 3.42.0 and first reported by forum post ee4f6fa5ab. (check-in: 460353df user: drh tags: trunk) | |
| 17:11 | Changes to vtabCallConstructor() to avoid a harmless static analyzer warning and to help prove that the UAF reported by forum post cafbe582e8 is a false-positive. (check-in: 4892440b user: drh tags: trunk) | |
|
2024-02-12
| ||
| 19:12 | Replace the assert() that was removed by [f023cb541b5dd72c] because [1cd5d4623f44af25] made it true again. (check-in: 189a49f1 user: drh tags: trunk) | |
| 17:01 | Have rtree avoid keeping a blob handle open following an error. (check-in: 26978f34 user: drh tags: branch-3.45) | |
| 14:44 | Add a new sqlite3FaultSim() to btree for better fault analysis. (check-in: 2c675bd3 user: drh tags: trunk) | |
| 13:51 | Add a new sqlite3FaultSim() call in the btree logic, for testing. (Closed-Leaf check-in: e0558f79 user: drh tags: new-btree-faultsim) | |
| 13:28 | Add support for the ".testctrl fault_install" dot-command in the CLI when launched with the --unsafe-testing option. (check-in: 5ba7fee1 user: drh tags: trunk) | |
|
2024-02-11
| ||
| 23:25 | Cherrypick multiple fixes for trifling faults from trunk, so that all 834 dbsqlfuzz run clean with ASAN on branch-3.45. dbsqlfuzz. (check-in: c080560c user: drh tags: branch-3.45) | |
| 22:56 | In the RTREE extension, allow the xBeginTransaction() entry point to be invoked multiple times without intervening calls to xEndTransaction(). (check-in: f023cb54 user: drh tags: trunk) | |
| 20:53 | If a term of an ORDER BY or GROUP BY contains an aggregate function or column, then it is not an alias that needs to be resolved, so don't try to. This fixes a harmless assertion found by dbsqlfuzz. This yet another problem that orginated at check-in [6e6b3729e0549de0]. (check-in: d4ec2a5d user: drh tags: trunk) | |
| 18:53 | Improved AggInfo tracing in debug builds. No changes to deliverable code. (check-in: bb31f9c4 user: drh tags: trunk) | |

|
2024-02-06
| ||
| 18:33 | Slight change to OOM handling in JSON to catch a corner case found by dbsqlfuzz. (check-in: 6a2b3266 user: drh tags: trunk) | |
| 13:36 | Return SQLITE_ABORT if the underlying shadow tables change in the middle of an rtree query in such a way as to invalidate an rtree internal priority queue entry. This replaces the SQLITE_ABORT_ROLLBACK mechanism added in [97cffff331b]. (check-in: 061af0d7 user: drh tags: branch-3.45) | |
|
2024-02-03
| ||
| 19:41 | Following a ROLLBACK that reverts changes to an RTREE, any pending queries against that same RTREE abort with code SQLITE_ABORT_ROLLBACK. (check-in: 97cffff3 user: drh tags: branch-3.45) | |

|
2024-02-01
| ||
| 14:57 | In PRAGMA integrity_check, defer running xIntegrity on virtual tables until after all ordinary tables have been checked. (check-in: 8f4b1cea user: drh tags: trunk) | |
| 14:17 | Add tracing logic to the shared-cache locks in btree.c. The tracing is off by default. Enable by changing a single "#if 0" into "#if 1" and recompiling. Debugging code only - no changes to release builds. (check-in: f2b943f9 user: drh tags: trunk) | |
| 11:38 | Add the test_oom_breakpoint() routine on debug builds, to serve as a convenient breakpoint to intercept OOM conditions. (check-in: e45df7dc user: drh tags: trunk) | |
