| 13:11 | Modify the %nonassoc directive in lemon so that it generates a run-time error rather than a parsing conflict. This changes is due to a bug report on the mailing list. SQLite does not use the %nonassoc directive in its grammar so this change does not affect SQLite. (check-in: 1925f3a0a2 user: drh tags: trunk) | |

| 19:36 | Always include the ctype.h header in the spellfix.c extension. (check-in: bfd75f471a user: drh tags: trunk) | |
| 19:13 | Avoid running a couple of test cases that use realloc() extensively if SQLITE_MEMDEBUG is defined. (check-in: e406d4bb78 user: dan tags: trunk) | |
| 19:04 | Fix a harmless compiler warning on MSVC. (check-in: 0723effc9c user: drh tags: trunk) | |

| 15:52 | Count the number of elements in a SrcList object using an "int" rather than a "u8", to avoid overflows and to work around an issue in the C compiler on AIX. (check-in: eee2a13f2c user: drh tags: trunk) | |

| 14:40 | When converting a result type from TEXT to BLOB using the sqlite3_value_blob() interface, continue to report SQLITE_TEXT as the true type from sqlite3_value_text() as long as that text is still valid. The maintains legacy behavior from before the noMemType change. (check-in: 1d134ba2ed user: drh tags: trunk) | |
| 12:47 | Separate the column NULL value constant into a separate routine for greater commonality with the sessions branch. (check-in: 12cbebb997 user: drh tags: trunk) | |
