| 14:26 | Rearrange things a bit so that writing to a zipfile does not invert the order of objects it contains. (check-in: f69e8194bf user: dan tags: sqlar-shell-support) | |

| 17:40 | Fix a crash that could occur following an OOM in the group_concat() function if the second argument is an SQLITE_BLOB value. (check-in: 14d855d2b2 user: dan tags: trunk) | |
| 15:16 | Strengthen the defense against OOM in the instr() SQL function. (check-in: a0971e7136 user: drh tags: trunk) | |
| 14:25 | Add a test to ensure that the app-defined pcache xFetch() method is never passed a key of zero. (check-in: 0bdbe49c6d user: drh tags: trunk) | |
| 14:15 | Avoid passing NULL pointers to memcmp() or memcpy(), even when the "number-of-bytes" argument is passed 0. (check-in: 56ff72ab44 user: dan tags: trunk) | |
| 14:11 | • Edit [5550e815dd943b15|5550e815dd]: Move to branch pcache1-zero-page. (artifact: 2600abce30 user: drh) | |
| 13:55 | Clarify the expectations for the behavior of the xFetch method on the sqlite3_pcache_methods object for the case when the key is zero. (Closed-Leaf check-in: b0810ac1b2 user: drh tags: pcache1-zero-page) | |
| 13:40 | Improved detection of zero page numbers in the page cache. (check-in: 5550e815dd user: drh tags: pcache1-zero-page) | |
| 12:10 | Fix a harmless compiler warning in fuzzcheck.c (check-in: 2842bc6053 user: drh tags: trunk) | |
| 12:06 | Disable the pagerAcquireMapPage() routine if memory-mapped I/O is disabled. This fixes a harmless compiler warning on OpenBSD. (check-in: 3e25ba6e42 user: drh tags: trunk) | |
| 00:09 | Encode a 64-bit integer literal in date.c as a constant expression so that it works on older compilers. Also fix a harmless compiler warning in vdbe.c. (check-in: f57952bac6 user: drh tags: trunk) | |

| 20:50 | Use the OvflOffset() macro to try to remove some magic numbers from btree.c. (Leaf check-in: 1541607d45 user: drh tags: ovfloffset-macro) | |
| 19:58 | Updates to fts5 to support detail=none mode. As of this commit, many cases are still broken. (check-in: ac8f4cf0ce user: dan tags: fts5-offsets) | |
| 18:18 | Reduce the size of the CellInfo object from 32 to 24 bytes on 64-bit machines, for a small performance increase and library size reduction. (check-in: 6a4cfc7ab6 user: drh tags: trunk) | |
| 17:03 | Enhance the command-line shell so that it can handle MBCS characters on input and output. (check-in: 3d81dfe3bc user: drh tags: trunk) | |
| 16:51 | Changes to the way that the default BINARY collating sequence is recorded result in a slightly smaller and slightly faster executable. More work could be done to make this cleaner. (check-in: 2081d75767 user: drh tags: trunk) | |
| 15:18 | Simplification to the xfer-optimization logic. (check-in: f35ba018da user: drh tags: trunk) | |
| 14:06 | Remove unnecessary tests from the LIKE pattern matcher. Slightly faster and slightly smaller, and it should also now works with EBCDIC. (check-in: 0a99a8c4fa user: drh tags: trunk) | |
| 13:36 | Enhance the command-line shell to handle MBCS characters on input and output. (Closed-Leaf check-in: a0a08b8c0b user: drh tags: mbcs-shell) | |
| 01:07 | Add the json_group_array() and json_group_object() aggregate functions to the JSON1 extension. (check-in: 7f386a9332 user: drh tags: trunk) | |

| 20:40 | Add the "mptester" tests to releasetest.tcl. (check-in: 93094a68d3 user: drh tags: trunk) | |
| 19:58 | Ensure that when a file is extended using FCNTL_SIZE_HINT the last page is allocated on disk, even if the file will only use part of it. (check-in: c7f84717d6 user: dan tags: trunk) | |
| 19:26 | Update the threadtest3 test program so that its output summary is compatible with releasetest.tcl. In threadtest3, do not record errors that contain the string "no such table" as being fatal errors, since they happen sometimes in a race condition in stress1. (check-in: 98cb56e240 user: drh tags: trunk) | |
| 18:07 | Fix problems with the "inmemory_journal" permutation. (check-in: 79693f0412 user: dan tags: trunk) | |
| 14:40 | If the sorter uses mmap'd temp files, ensure all pages of the temp file have been allocated before it is accessed. Otherwise, a disk-full condition might result in a SIGBUS exception. (check-in: 776648412c user: dan tags: trunk) | |
| 13:04 | Make SQLITE_CONFIG_PCACHE_HDRSZ accurate (not an over-estimate) on 32-bit systems. (check-in: 340b347758 user: drh tags: trunk) | |
| 12:03 | Change notify2.test to check that sqlite3_blocking_step() uses CPU more efficiently than sqlite3_step(), not that it results in greater overall throughput for any specific number of threads. (check-in: d904d29354 user: dan tags: trunk) | |
| 00:57 | Round all object sizes that go into computing SQLITE_CONFIG_PCACHE_HDRSZ up to a multiple of 8 bytes. (check-in: b28ce75f2d user: drh tags: trunk) | |

| 16:35 | Add LEFT JOIN test cases for multi-index OR in where9.test. (CVS 6085) (check-in: 96f3b62914 user: drh tags: trunk) | |
| 16:18 | Get EXPLAIN QUERY PLAN working with the multi-index OR optimization. Added new test script "where9.test". (CVS 6084) (check-in: 4b64602210 user: drh tags: trunk) | |
| 16:13 | Add further pseudo-randomly generated test cases to where8.test. (CVS 6083) (check-in: e01f6ef9d9 user: danielk1977 tags: trunk) | |

| 14:14 | Add many new test cases to where7.test. (CVS 6079) (check-in: 174985831f user: drh tags: trunk) | |
| 13:21 | Do not run savepoint4.test (crash simulation tests) in permutations.test. It slows things down too much. (CVS 6078) (check-in: 2df02b543e user: danielk1977 tags: trunk) | |
| 12:00 | Add a couple of extra tests for the "WHERE ... OR" optimization. (CVS 6077) (check-in: 35c87585b8 user: danielk1977 tags: trunk) | |
| 09:45 | Fix a bug in where.c causing a malfunction when an INDEXED BY clause specified an unusable index on other than the leftmost table in the FROM clause. Ticket #3560. (CVS 6076) (check-in: f8ff021212 user: danielk1977 tags: trunk) | |
| 06:36 | Fix a bug in README.tokenizers. Ticket #3559. (CVS 6075) (check-in: b8898d132e user: danielk1977 tags: trunk) | |
