| 21:33 | The fts3_tokenizer() function returns NULL if the SQLITE_DBCONFIG_ENABLE_FTS_TOKENIZER setting is disabled, which is is by default. (check-in: f5732f4caf user: drh tags: trunk) | |
| 21:12 | Fix a minor comment typo. No code changes. (check-in: 9a0a93c89d user: drh tags: trunk) | |
| 18:27 | Merge the latest enhancements from trunk. (check-in: e64ded7b04 user: drh tags: apple-osx) | |
| 18:07 | In a query that uses a partial index, the expression that is the WHERE clause of the partial index must always be true. Use this fact to avoid evaluating identical terms in the WHERE clause of the query. (check-in: 9b2879629c user: drh tags: trunk) | |

| 15:20 | Fix further crashes in sqlite3changeset_apply() caused by corrupt changeset blobs. (check-in: 2c01c72e35 user: dan tags: trunk) | |

| 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) | |
| 20:00 | Fix minor problems with new code in memjournal.c. (check-in: 9fd3f7b9c9 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) | |
| 15:53 | Reduce the amount of heap required to store many schemas by storing each column datatype appended to the column name, rather than as a separate allocation. (Closed-Leaf check-in: 842b211627 user: drh tags: schema-storage) | |
| 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) | |
