| 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) | |

| 22:45 | For the shell '.import' command, make sure the last column value present is considered before NULL filling any missing ones. (check-in: 9c5bcad1f7 user: mistachkin tags: trunk) | |
| 17:15 | Improve the performance of fts3/4 queries that use the OR operator and at least one auxiliary fts function. Cherrypick of [245e8730451f]. (check-in: b20824628f user: dan tags: branch-3.8.8) | |

| 22:43 | Added experimental mutex implementation using interlocked ops and spin locks. (Closed-Leaf check-in: f3676b243d user: shaneh tags: experimental) | |
| 19:46 | Enhancements to the secure_delete pragma to make it easier to use. (check-in: 2bb38bb96f user: drh tags: trunk) | |
| 18:35 | • Edit [f72f8a870a0fc98a|f72f8a870a]: Edit check-in comment. Timestamp 2010-02-12 18:18:39. (artifact: dc30e13d72 user: drh) | |
| 18:18 | Allow the secure-delete setting to be changed at run-time using a pragma. The SQLITE_SECURE_DELETE compile-time option determines the default setting. (check-in: f72f8a870a user: drh tags: trunk) | |

| 08:59 | Fix a problem with sub-queries and the flattening optimization. Also handle an extra case of database corruption. (CVS 2324) (check-in: f7858d8830 user: danielk1977 tags: trunk) | |
| 00:19 | Fix a problem with VACUUM that can lead to database corruption. (CVS 2323) (check-in: 63894baf1b user: drh tags: trunk) | |
