| ||
| 22:48 | New test cases and infrastructure for testing the xBestIndex method of virtual tables. (check-in: 1d41c16116 user: drh tags: trunk) | |
| 22:41 | Improved debugging output with wheretrace. Fix some typos in test script comments. (check-in: 13a37fd487 user: drh tags: trunk) | |
| 18:35 | Fix a memory leak in the test code on this branch. (Closed-Leaf check-in: 7a1add5634 user: dan tags: test-bestindex) | |
| 18:24 | Allow test_bestindex.c to set the omit flag for a constraint. (check-in: 759b9d5b22 user: dan tags: test-bestindex) | |
| 18:07 | Add test code useful for testing the planners use of teh virtual table xBestIndex() method. (check-in: de034c0db6 user: dan tags: test-bestindex) | |
| 14:31 | Change the estimated row counts in stat1 to be one-third worst-case and two-threads average case. (check-in: 21bfd47c42 user: drh tags: analyze-worst-case) | |

| ||
| 23:02 | Improvements to the logic for adding the "noskipscan" flag to stat1 entries. (check-in: 421b5b544a user: drh tags: analyze-worst-case) | |
| 21:27 | The ANALYZE command automatically appends "noskipscan" to sqlite_stat1 entries that have large worst-case repeat estimates but small average repeat estimates. (check-in: 6326ba5891 user: drh tags: analyze-worst-case) | |
| 20:18 | When using a temporary file for a statement journal, store the first 64KiB in memory. If the file grows larger than that, flush it to disk and free the memory. Hardcoding to 64KiB is just an experiment to check that the memjournal.c code works. (check-in: 44b2dc18e2 user: dan tags: memjournal-exp) | |

| 18:30 | Modify the ANALYZE command to store worst-case statistics in sqlite_stat1, rather thn average case. (check-in: 5a0143c94e user: drh tags: analyze-worst-case) | |
| 17:34 | Fix a problem in fts5 where a corrupt db could lead to a (huge) buffer overread. (check-in: c9a30e117f user: dan tags: trunk) | |
| 17:16 | Fix an fts5 problem causing 'optimize' to corrupt the fts index under some circumstances. (check-in: 251d6473f7 user: dan tags: trunk) | |
| 13:44 | Very minor improvement to the performance and reduction in size to the parser by capturing the name and datatype of table columns in a single grammar rule reduction. (check-in: 4b55c520f5 user: drh tags: trunk) | |
| 13:37 | Further simplifications to the grammar. (Closed-Leaf check-in: 519fd03b84 user: drh tags: schema-storage) | |
|

| 23:25 | Update the parser so that it pulls out the column name and type all in one go, rather than using separate reductions. (check-in: ad3ffe2eec user: drh tags: schema-storage) | |
| 21:16 | Eliminate the need for the Column.zDflt (using Column.pDflt instead) to reduce the amount of memory needed to hold the schema. (check-in: d8c94a46df user: drh tags: trunk) | |
| 20:14 | Extend the code in memjournal.c so that it subsumes the role of journal.c. And (untested) can flush journal or statement journal files to disk after they grow to a specified size. (check-in: e0b0b43165 user: dan tags: memjournal-exp) | |
| 19:19 | Tighter description of I/O stats in the shell. Show I/O stats on speedtest1.c. (check-in: f681d80034 user: drh tags: trunk) | |
| 19:03 | More compact implementation of PRAGMA onconflict, and some test cases. (Leaf check-in: 3e5d38f5b3 user: drh tags: pragma-onconflict) | |
| 17:16 | Experimental "PRAGMA onconflict=FAIL" statement to change the default ON CONFLICT algorithm to something other than ABORT. (check-in: 3a0c347cca user: drh tags: pragma-onconflict) | |
| 17:12 | Enhance the ".stats" command in sqlite3.exe to show one-time stats information if invoked with one argument. Also show /proc/PID/io information if run on Linux. (check-in: 3c36948f16 user: drh tags: trunk) | |
| 14:04 | Fix a requirement mark to conform to a typo fix in the documentation. (check-in: d1392c6279 user: drh tags: trunk) | |
| 14:00 | Enhance documentation of sqlite3_snapshot_open() to explain that the database connection must have participated in at least one read operation prior to the beginning of the transaction for which the snapshot is to be opened. Add test cases for this fact. (check-in: 33dd671cb9 user: drh tags: trunk) | |
| 00:21 | Add 'Replace.exe' to the MSVC clean target. (check-in: c2277fab12 user: mistachkin tags: trunk) | |
| 00:21 | Fix typo in ICU error message. (check-in: 00c8fffd47 user: mistachkin tags: trunk) | |
| 00:07 | Make sure the Replace.cs file is included in the autoconf tarball. (check-in: b850df483d user: drh tags: trunk) | |

| 23:13 | Support generating the '.def' file using the autoconf Makefile for MSVC. (check-in: 3617564cb6 user: mistachkin tags: trunk) | |
| 21:20 | Fix a potential buffer overflow in the ICU upper() function. (check-in: b8dc1b9f5d user: drh tags: trunk) | |
| 21:03 | Further refinements to the MSVC batch build process. (check-in: cf4e4fbdb6 user: mistachkin tags: trunk) | |
| 16:14 | Merge all recent enhancements from trunk, and in particular the SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER change. (check-in: 4fb4aee83d user: drh tags: apple-osx) | |
| 16:03 | Fix the ICU extension LIKE function so that it does not read past the end of a buffer if it it passed malformed utf-8. (check-in: 424b7aee33 user: dan tags: trunk) | |
| 15:38 | Provide the new SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER option to sqlite3_db_config() that can be used to activate the two-argument version of fts3_tokenizer() for a specific database connection at run-time. (check-in: 374b510808 user: drh tags: trunk) | |
| 13:22 | Fix a typo in a comment (though an important comment in that it is used to generate documentation). (check-in: ff3d7f845e user: drh tags: trunk) | |
| 04:13 | Ephemeral tables used to hold manifested views may not be unordered since they might be subject to an ordered comparison if they are part of a join. (check-in: 3ef6a31532 user: drh tags: trunk) | |
