| 21:51 | If a reprepare is needed after binding to a variable with a number larger than 32, set only the high-order bit of the Vdbe.expmask rather than setting all bits. This could potentially result in fewer false-positive reprepares. check-in: 45797fee user: drh tags: trunk | |
| 21:36 | Remove an redundant function call from the date/time function implementation. check-in: 4a04c48a user: drh tags: trunk | |
| 20:43 | Fix another corner-case for the 'start of ...' modifier in the date/time functions. Related to ticket [6097cb92745327a1]. check-in: 8831f439 user: drh tags: trunk | |
| 20:02 | Fix a case introduced by [4cd2a967] where a corrupt database could cause a buffer overwrite. check-in: 5d0455fe user: dan tags: trunk | |
| 16:51 | Before beginning an incremental checkpoint in RBU, sync the directory containing the target database file. This ensures that the new directory entry created by renaming the *-oal file to *-wal is synced to disk. check-in: 915a9a28 user: dan tags: trunk | |

| 14:51 | When saving the state of an RBU update in the incremental-checkpoint phase, sync the database file. Otherwise, if a power failure occurs and the RBU update resumed following system recovery, the database may become corrupt. check-in: edee6a80 user: dan tags: trunk | |

| 02:04 | Fix a test case that was made to fail by the LIKE optimization enhancement in check-in [158290c0ab] but which went unnoticed because test builds were running with ICU enabled and ICU disables the LIKE optimization. check-in: 218b2bbb user: drh tags: trunk | |

| 18:30 | Minor enhancement to mutex tracing on Win32. check-in: 830b9235 user: mistachkin tags: trunk | |
| 15:09 | Remove the CLANG_VERSION macro, since we have learned that version numbers in clang are "marketing" and are inconsistent and unreliable. Builds using clang will still use the GCC_VERSION macro since clang works hard to be gcc compatible. check-in: 810d2932 user: drh tags: trunk | |
