|
2024-01-01
| ||
| 17:58 | Remove some unnecessary computations from ANALYZE so that ANALYZE runs with fewer CPU cycles. These changes were spotted while working on the nearby enhanced-stat1 branch. So even if enhanced-stat1 is abandoned, that effort put into it will not have been in vain. (Closed-Leaf check-in: 5527e8c4 user: drh tags: avoid-low-quality-indexes) | |

Work around this by restricting the range of doubles that are converted into long long integers so that only the lower 63 bits are used. (Closed-Leaf check-in: 0ab05871 user: drh tags: legacy-msvc-workaround) | |

|
2023-09-09
| ||
| 11:20 | In the JNI build, emit a reminder to not check in the javac-generated sqlite3-jni.h when FTS5 is disabled because changes in that feature flag result in unnecessary and large diffs in checked-in generated code. (Closed-Leaf check-in: caceb52f user: stephan tags: jni-client-data) | |

|
2023-08-07
| ||

|
2023-08-02

|
2023-07-28
| ||
| 12:59 | A failed attempt to add a new sqlite3_result_zeroterminated() interface that is a hint to SQLite that a TEXT result does have a zero terminator. The idea is to avoid unnecessary copying of TEXT values. This seems like an unnecessary complication at the moment, but maybe I'll return to this later. Note that this check-in does not work - it is a proof of concept only. (Closed-Leaf check-in: a0de0110 user: drh tags: sqlite3_result_zeroterminated) | |

| 12:52 | Enhance the JSON parser cache such that it is able to extract lines from the cache and use them for writing, though they then have to be evicted from the cache. This was an experiment in trying to reduce the amount of parsing needed for a big UPDATE, but it does not seem to help any. Retained for reference only.

|
2023-06-21
| ||
| 18:12 | This is a failed attempt to optimize the usage of the page cache in sqlite3BtreeIndexMoveto() by deferring calls to sqlite3PagerUnref() for child pages of the btree until we are sure those pages will not be reused. The code does not work in two senses: (1) Many tests still fail. (2) The performance gain is less than 2 million cycles and does not seem worth the extra risk and complication. (Closed-Leaf check-in: 84731a1f user: drh tags: pcache-opt) | |
|
2023-06-14
| ||
| 13:45 | Add SQLITE_DBCONFIG_RANDOM_SCANORDER. This option causes unconstrained table and index scan to happen in a random order, in order to help detect under-constrained queries in applications. Closed because this feature does not add any new capabilities that are not already available with SQLITE_DBCONFIG_REVERSE_SCANORDER, but it does make the behavior non-deterministic, and hence more difficult to test. (Closed-Leaf check-in: 33021986 user: drh tags: random-scanorder) | |

| ||
| 00:05 | Modify the OP_IsType opcode so that it does not need to distinguish between NaN and other floating point values. Later: This branch causes an unnecessary slowdown of PRAGMA integrity_check. Check-in [7638d9755dc90fd3] does a better job of detecting when a NaN value occurs in a NOT NULL column. (Closed-Leaf check-in: 242cb36c user: drh tags: istype-opcode-refactor) | |

| 20:22 | Reinsert two NEVER() macros for b-tree branches that were previously needed for [b6a82f3c3b9d89fd] but which are now obsolete due to [73f0036f045bf371]. Later: dbsqlfuzz quickly found new cases for which those two branches are needed. The new test cases have been added to TH3. (Closed-Leaf check-in: 3065dadb user: drh tags: backout) | |

| 17:50 | If OP_Rewind has P2 of zero, that is an assertion that the table is never empty. This fixes a false-positive in the out-of-subroutine jump detection logic added in version 3.39.0, and which was causing the assertion on the previous check-in.

| 14:41 | If the SELECT that implements a subquery or a VIEW or a CREATE TABLE AS is a compound with different result datatypes on two or more arms of the compound, then the overall column type becomes BLOB (ANY). (Closed-Leaf check-in: 6ebb178c user: drh tags: refactor-subquery-types) | |
|
2022-12-12
| ||
| 18:58 | If a subquery has a result column of the form "CAST(... AS NUMERIC)" then give that column no affinity rather than NUMERIC affinity. This is because casting to numeric preserves real values that could be integers but numeric affinity does not. By using no affinity on the column, we make the behavior consistent if the subquery is implemented as a co-routine or is materialized.

| 23:28 | I was a little concerned about this check-in. Though I could not generate a failure myself, I thought it was risky. I checked it in for further testing. Then, overnight, OSSFuzz found a failure case for me. So the change is now moved out into a deadend branch. Was: Use OP_SCopy rather than OP_Copy to transfer results from a co-routine to its consumer. This undoes an earlier fix for ticket [98825a79ce] by check-in [ec6a06246e] because that problem no longer occurs due to WHERE clause push-down.

This code was not able to detect anomalies such as came up as a result of ticket [e4a18565a36884b00edf66541f38c693827968ab] so it is put into a branch for historical reference, with the intent of leaving it out of trunk.

| 04:38 | Experiment using linear interpolation, instead of a strict binary search, when looking for integer-keyed rows on a single b-tree page. The experiment was not successful. The number of key comparisons is reduced by about 15%, but the added complexity of the search logic causes an overall reduction in performance. The patch is saved for historical reference only.

|
2014-08-01
| ||
| 15:34 | The idea of coding IN operator with a short list on the RHS as an OR expression turns out to be helpful. If the list is of length 1 or 2, the OR expression is very slightly faster, but the ephemeral table approach is clearly better for all list lengths greater than 2. Better to keep the code simple.

| 22:45 | A much simpler fix is to simply change MEMSYS5 so that it takes any free block of the appropriate size (the first on the list of free blocks) rather than searching for the one with the smallest address. This is also faster than using the min-heap algorithm. Need to research to verify that the allocator still satisfies the Robson proof, however.

| ||
| 18:22 | Disable the table selection rule that tried to prevent full table scans from migrating to the outer loop unless they were optimal. The new scaling of outer-loop costs by cost of inner loops obviates the need for that step. And, in fact, that step causes problems with the new inner-loop cost accounting.

|
2012-09-27
| ||
| 23:27 | Fix some corner case behavior in the new ORDER BY optimization logic. Remove the SQLITE_OrderByIdx bit from the SQLITE_TESTCTRL_OPTIMIZATIONS mask, since enabling it caused many TH3 tests to fail when the NO_OPT configuration parameter was engaged, and since there really isn't any need to turn that optimization off. The SQLITE_OrderByIdxJoin bit remains. (Closed-Leaf check-in: 98b63371 user: drh tags: qp-enhancements) | |

| 12:10 | This branch merged with nx-devkit and from there into trunk. Was: In the multiplexor, instead of generating a unique file-name when SQLite opens a temp file, allow the underlying VFS to generate a different temp file for each chunk. Given the changes to the xFileSize method, it is no longer necessary for the different chunks of a temp file to use the same base name.

|
2011-08-23

|
2011-05-13

2011-01-11
| ||
| 01:42 | A proposed change to the sqlite3_step() API such that it will only auto-reset following an SQLITE_BUSY or SQLITE_LOCKED error. Calls after any other result other than SQLITE_ROW will return SQLITE_MISUSE. (Closed-Leaf check-in: d1b3c54f user: drh tags: step-autoreset) | |
