| ||
| 02:57 | Add the exprNodeCopy() routine that will safely memcpy() an Expr node that might be a size-reduced node. (Leaf check-in: ab2ba8e732 user: drh tags: expr-node-copy-patch) | |
|
2018-06-07
| ||
| 20:08 | Add window functions lag() and lead(). (check-in: ef34207073 user: dan tags: exp-window-functions) | |
| 17:45 | Add support for window function first_value(). (check-in: 060b264028 user: dan tags: exp-window-functions) | |
| 15:54 | Fix problems with the nth_value() function. (check-in: 63002b9a09 user: dan tags: exp-window-functions) | |
|
2018-06-06
| ||
| 20:51 | Add implementation of nth_value() window function. (check-in: eb1fb420ac user: dan tags: exp-window-functions) | |
| 00:36 | Attempt to optimize the resolveExprStep() routine by mapping Expr opcodes into a subset of opcodes that resolveExprStep() cares about and only calling the routine when those opcodes are encountered. Is slightly faster, but it seems like the very slight performance bump is not worth the added complexity. Saved on a dead-end branch for historical reference. (Closed-Leaf check-in: bad4d7a0d9 user: drh tags: dead-end) | |

| 23:51 | Update the version number to 3.25.0 for the next development cycle. (check-in: 7598236c35 user: drh tags: trunk) | |
| 23:21 | Avoid unnecessary loads of columns in an aggregate query that are not within an aggregate function and that are not part of the GROUP BY clause. (check-in: e15e100660 user: drh tags: trunk) | |
| 20:45 | Add the OP_IfNoHope and OP_SeekHit opcodes used to reduce the number of unnecessary sqlite3BtreeMovetoUnpacked() calls when checking for an early exit on IN-operator loops. Futher optimizations are likely possible here. (check-in: 6bf251af43 user: drh tags: multikey-opt-idea) | |
| 20:04 | Calculate non-aggregate expressions in the SELECT list of an aggregate query that does not use min() or max() once per group, instead of once per row visited. (Closed-Leaf check-in: dce2dfbe15 user: dan tags: exp-agg-opt) | |
| 16:16 | Add implementation of last_value() window function. (check-in: 2493ce1a40 user: dan tags: exp-window-functions) | |
| 15:16 | Use an OP_NotFound opcode to cancel futile IN operators early. The current implementation is suboptimal because it always runs teh OP_NotFound. This still needs to be enhanced to only do the OP_NotFound if no results have been seen on the current loop. (check-in: 87a9fc504f user: drh tags: multikey-opt-idea) | |
| 13:54 | Merge trunk changes. (check-in: 047295c588 user: drh tags: multikey-opt-idea) | |
| 13:43 | Update and correct the documentation on the OP_OpenRead, OP_OpenWrite, and OP_ReopenIdx opcodes. No code changes other than the addition of an assert(). (check-in: 8a0b730d0e user: drh tags: trunk) | |

| 19:24 | Version 3.24.0 (check-in: c7ee083322 user: drh tags: trunk, release, version-3.24.0) | |
| 18:55 | Add implementation of window function ntile(). (check-in: 3f093f608c user: dan tags: exp-window-functions) | |
| 14:10 | Merge changes from trunk. (check-in: 95fbac39ba user: drh tags: apple-osx) | |
| 13:27 | Merge recent changes from trunk. (check-in: f8df2a8e28 user: drh tags: multikey-opt-idea) | |
| 08:28 | Merge latest trunk changes into this branch. (check-in: 83d6416a86 user: dan tags: exp-window-functions) | |

| ||
| 19:14 | Avoid using a misaligned pointer. (check-in: 1ecb3aa13d user: drh tags: trunk) | |
| 19:01 | Fix the usage of posix_fallocate() so that it correctly responds to EINVAL returns. (check-in: ce2c3e7a87 user: drh tags: trunk) | |
| 17:00 | Update a test case in malloc5.test to take into account that malloc() sometimes returns slightly more space than requested. (check-in: 3d5eae1c26 user: dan tags: trunk) | |
| 16:32 | Work around a sanitizer warning about a pointer being only 4-byte aligned instead of 8-byte aligned. (Closed-Leaf check-in: 1b807b51cd user: drh tags: align8-fix) | |
| 14:37 | Proposed fix for the use of posix_fallocate() so that it handles EINVAL returns correctly. (Closed-Leaf check-in: ab3a5539db user: drh tags: einval-from-fallocate) | |
| 12:05 | Fix the CSV extension so that it works with single-column CSV files. (check-in: e336cf0048 user: drh tags: trunk) | |
| 11:31 | Ensure that sqlite3AuthRead() is only call for TK_COLUMN and TK_TRIGGER expression nodes. This fixes a harmless assert() identified by OSSFuzz. Move the assert() into a position where it is tested even if the authorizer is disabled. (check-in: d0c3beef7c user: drh tags: trunk) | |
|
2018-06-01
| ||
| 13:30 | Fix a bug in the SQLITE_ENABLE_SORTER_REFERENCES code causing an out-of-bounds array reference. (check-in: 8cadaf587d user: dan tags: trunk) | |
|
2018-05-31
| ||
| 19:14 | More documentation typo fixes. No code changes. (check-in: 66c24513c2 user: drh tags: trunk) | |
| 19:00 | Fix a harmless typo in a comment used to generate documentation. (check-in: 5a2a88cb01 user: drh tags: trunk) | |
|
2018-05-30
| ||
| 14:17 | Add the Makefile.fallback makefile to the amalgamation tarball. (check-in: ce3d045633 user: drh tags: trunk) | |
| 07:36 | Do not use the codec on the resetdb.test script. (check-in: fe55cea0c8 user: drh tags: trunk) | |
| 07:24 | Fix a typo in an error message in the CLI. (check-in: 8088398081 user: drh tags: trunk) | |
