| 22:34 | Small performance improvement and size reduction for pageFindSlot() - the routine in btree.c that locates a free slot for a cell on a btree page. (check-in: 1969372ac7 user: drh tags: trunk) | |
| 20:55 | Use a fast compiler-provided memory barrier exclusively, if such a memory barrier is available. (Leaf check-in: df66fec9bc user: drh tags: faster-memory-barrier) | |
| 19:30 | Add test cases and fix problems on this branch. (check-in: 2b2e9f81cd user: dan tags: reuse-schema) | |
| 17:28 | Further simplifications to sqlite3VdbeMemSetStr(). (check-in: 1d21295707 user: drh tags: trunk) | |
| 15:59 | Change the sqlite3VdbeMemGrow() routine so that it no longer guarantees a minimum size of 32 bytes. That minimum is no longer required, and without the extra check for the minimum size, the routine runs faster. (check-in: 5c499da8a4 user: drh tags: trunk) | |
| 14:59 | Merge the fix for ticket [4e8e4857d32d401f], so that this branch now contains release 3.27.1 plus the extra patch to preserve ROWID values on VACUUM. (check-in: 0cdae60ed7 user: drh tags: apple-osx) | |
| 14:55 | Give the sqlite3 object a pointer to the current Parse so that if an OOM occurs, it can automatically set the Parse.rc value to SQLITE_NOMEM. This avoids a frequent extra test of db.mallocFailed in the innermost parser loop. (check-in: 5c6638040b user: drh tags: trunk) | |
| 13:17 | Version 3.27.1 (check-in: 0eca3dd3d3 user: drh tags: release, branch-3.27, version-3.27.1) | |
| 13:02 | • Edit [a47efb7c8520a011|a47efb7c85]: Edit check-in comment. (artifact: b72a6b96f8 user: drh) | |
| 12:46 | Cherrypick the fix for ticket [4e8e4857d32d401f] from trunk. (check-in: d5d944d794 user: drh tags: branch-3.27) | |
| 12:44 | Increase the version number to 3.27.1. (check-in: b94d5428bb user: drh tags: branch-3.27) | |
| 04:20 | • Fixed ticket [4e8e4857d3]: Crash on query using an OR term in the WHERE clause plus 6 other changes (artifact: f29e381b52 user: drh) | |
| 04:15 | Do not do the optimization that attempts to pull expression values from an index on that expression when processing a multi-index OR (see check-in [a47efb7c8520a0111]) because the expression transformations that are applied become invalid when the processing moves off of the current index and on to the next index. Fix for ticket [4e8e4857d32d401f]. (check-in: 440a7cda00 user: drh tags: trunk) | |
| 03:01 | • New ticket [4e8e4857d3] Crash on query using an OR term in the WHERE clause. (artifact: 006561ff01 user: drh) | |

| 19:12 | Avoid preparing a SELECT statement each time an UPDATE or DELETE by docid is executed against an fts3 table. (check-in: 1afec5758b user: dan tags: trunk) | |
| 19:10 | Avoid preparing a SELECT statement each time an UPDATE or DELETE by docid is executed against an fts3 table. (Leaf check-in: 9962c10a5c user: dan tags: fts3-seekstmt-cache) | |
| 18:13 | Typo fixes in comment. No changes to code. (check-in: c09dd5c0be user: mistachkin tags: trunk) | |
| 16:55 | Merge the 3.17.0beta changes from trunk. (check-in: 92dbd8753e user: drh tags: apple-osx) | |
| 16:01 | Always invoke the xRoundup() method of the memory allocator before calling xMalloc(). (check-in: 77b470b0df user: drh tags: trunk) | |
| 12:18 | Round up the size of all memory allocations to a multiple of 8 bytes when using the system memory allocator. (check-in: c46e06fab4 user: drh tags: trunk) | |

| 22:22 | • New ticket [d06a25c844] Incorrect result from a UNION with an ORDER BY. (artifact: 4685201918 user: drh) | |
| 20:45 | Fix spelling error in MSVC makefile comments. (check-in: 6eab74c9ae user: mistachkin tags: trunk) | |
| 20:40 | More work on Windows 10 SDK integration. (check-in: 1e563c6ebb user: mistachkin tags: trunk) | |
| 20:14 | Fix a signed/unsigned comparison warning in fts5. (check-in: 85eb05ddbc user: dan tags: trunk) | |
| 20:06 | Fix a compiler warning when compiling without SQLITE_ENABLE_FTS3_TOKENIZER. (check-in: 6926f28cd5 user: drh tags: trunk) | |
| 19:40 | Disable the two-argument form of the fts3_tokenizer() SQL function unless the library is built with -DSQLITE_ENABLE_FTS3_TOKENIZER. (check-in: e0eb217aca user: dan tags: trunk) | |
| 19:36 | Changes to help the tokenizer run about 33% faster. (check-in: a050e6f096 user: drh tags: trunk) | |
| 19:15 | Add code to get the tokenizer character-class logic working for EBCDIC. (Closed-Leaf check-in: 04f7da77c1 user: drh tags: tokenizer-char-class) | |
| 03:23 | Faster keywordCode() implementation by taking advantage of the fact that the input is always pure ASCII alphabetic and underscore and that the keyword table is always upper-case. (check-in: ff406b9701 user: drh tags: tokenizer-char-class) | |
| 02:30 | Demonstrate a much faster sqlite3GetToken() routine by using a lookup table to map initial token characters into a character class. This check-in does not work for EBCDIC. More optimization needed. (check-in: 9115baa191 user: drh tags: tokenizer-char-class) | |
