| 20:50 | Increase the default upper bound on the number of parameters in a single SQL statement to 32766 (from 999). (check-in: 2def75693a user: drh tags: trunk) | |
| 13:02 | • Fixed ticket [fb8c538a8f]: Incorrect sorting when a column uses BINARY collation in the ORDER BY, but is constrained by an == with a different collation in the WHERE clause plus 3 other changes (artifact: 96f91c7db6 user: drh) | |
| 11:57 | When determining whether an == or IS constraint in a WHERE clause makes an ORDER BY term redundant, consider the collation sequence used by the == or IS comparison, not the collation sequence of the comparison expression itself. Possible fix for [fb8c538a8f]. (check-in: 16aed5d0c6 user: dan tags: trunk) | |
| 11:18 | • Ticket [fb8c538a8f] Incorrect sorting when a column uses BINARY collation in the ORDER BY, but is constrained by an == with a different collation in the WHERE clause status still Open with 6 other changes (artifact: 19ffc8588b user: drh) | |
| 06:21 | • New ticket [fb8c538a8f]. (artifact: c83cd179b0 user: dan) | |

| 22:58 | Ensure that the nProgressLimit variable is always initialized in sqlite3VdbeExec(), even if the routine jumps to its exit processing early. (check-in: 167b91df77 user: drh tags: trunk) | |
| 21:04 | Enhancement the progress callback mechanism so that the progress callback is always invoked at least once at the end of a prepared statement if the opcode count has been exceeded. This makes the progress callback more effective at limiting run times. This check-in also includes and unrelated performance enhancement to OP_Column. (check-in: 68cce272e7 user: drh tags: trunk) | |
| 20:58 | Add tests for creating temp schema objects with SQLITE_OPEN_REUSE_SCHEMA connections. (check-in: 8c07b609fc user: dan tags: reuse-schema) | |
| 19:20 | Share schemas between databases attached to the same database handle. (check-in: ea611d7cba user: dan tags: reuse-schema) | |
| 16:58 | Further performance improvements to btreeInitPage(). (check-in: 93ae382e97 user: drh tags: trunk) | |
| 15:51 | Increase the version number to 3.28.0 for the next release cycle. (check-in: 6eb38c59a8 user: drh tags: trunk) | |
| 12:25 | Register the "vfsstat" virtual table immediately when loading the vfsstat.c extension. (check-in: 9bd92afd0c user: drh tags: trunk) | |
| 01:28 | New test cases in test/fuzzdata8.db. (check-in: ab2356f580 user: drh tags: trunk) | |
| 01:04 | Defer computing the number of bytes of free space on a btree page until that value is actually needed. (check-in: 177f5f40ea user: drh tags: trunk) | |
| 00:58 | Change an assert() into a NEVER(), since the condition is difficult to prove with certainty. Improved comment on the MemPage.nFree field. (Closed-Leaf check-in: fec071b89d user: drh tags: deferred-free-space) | |

| 20:50 | Updates to the speed-check.sh script for improvements to the --vdbeprofile option. (check-in: f89c8f8ecd user: drh tags: trunk) | |
| 20:27 | When compiling with VDBE_PROFILE, add the sqlite3NProfileCnt global variable which can be used to measure per-opcode values other than elapse time, if non-zero. (check-in: d44d593642 user: drh tags: trunk) | |
| 20:04 | Add support for reading simple (no compression, no encryption) zonefile files. (check-in: dba42f0e1e user: dan tags: zonefile) | |
| 15:27 | Update test file func6.test so that it works with SQLITE_ENABLE_NULL_TRIM builds. (check-in: e128d72f1a user: dan tags: trunk) | |
| 13:30 | Fix a possible infinite loop in VACUUM that can come up when the schema has been carefully corrupted. Problem discovered by OSSFuzz. Test cases in TH3. (check-in: 27754b74dd user: drh tags: trunk) | |

| 18:48 | Fix a potential buffer overread provoked by invalid utf-8 in fts5. (check-in: a049fbbde5 user: dan tags: trunk) | |
| 17:56 | Fix a fairly obscure buffer overread in fts5. (check-in: 130580207a user: dan tags: trunk) | |
| 17:30 | Fix a documentation typo. No changes to code. (check-in: d9c985878c user: drh tags: trunk) | |
| 17:27 | Enhance mptester so that it takes great care to delete its test database prior to start-up, including checking the return code from unlink() and retrying after a delay if unlink() fails. Hopefully this will clear intermittant startup problems on Windows. (check-in: 6ea84ec1e0 user: drh tags: trunk) | |
| 05:19 | Naming updates for Universal Windows Platform. (check-in: 717c1fc41a user: mistachkin tags: trunk) | |
| 00:13 | Remove an unused parameter from whereSortingCost(). (check-in: b5d7719916 user: drh tags: trunk) | |

| 14:23 | Fix the expected output on tests so that it corresponds to the new query planner results. All of veryquick.test is now passing with SQLITE_ENABLE_STAT2. (check-in: f2a8b5ccfb user: drh tags: branch-3.7.2) | |
| 14:11 | • Edit [a586a4deeb253300|a586a4deeb]: Add tag "version-3.7.4". (artifact: f422ba096e user: drh) | |
| 05:34 | Fix problems in the backport, reducing the number of errors in the TCL tests to just a few dozen. Most of the remaining errors seem to be real and desirable changes of behavior. (check-in: 9d2b0af266 user: drh tags: branch-3.7.2) | |
| 01:59 | This is the beginning of an attempt to backport recent query planner enhancements to version 3.7.2. The code in this version builds and runs and seems to give correct answers, but it generates suboptimal query plans and hence many of the test cases fail. The test script gives up after 1000 errors. (check-in: e72cf118cb user: drh tags: branch-3.7.2) | |
| 00:14 | • Edit [42537b60566f2881|42537b6056]: Add tag "version-3.7.2". (artifact: e7912fe2f6 user: drh) | |
