For Windows 8.x and higher, require the SQLITE_WIN32_WIN8_SECTOR_SIZE compile-time option in order to enable sector size determination. Leaf check-in: 47beb55c user: mistachkin tags: winSectorSize
19:36
Improve and update comments. check-in: 2dc16d34 user: mistachkin tags: winSectorSize
19:06
Minimize the requested permissions when opening the volume on Windows 7 and Vista. check-in: 8d429a59 user: mistachkin tags: winSectorSize
01:11
Add runtime version checking for winSectorSize. check-in: cb9d1ab3 user: mistachkin tags: winSectorSize
00:27

16:01
Add test cases for tickets [91e2e8ba6ff2e2] and [7ffd1ca1d2ad4ec]. check-in: 9d0dfe0b user: drh tags: automatic-index-affinity

22:21
Merge updates from trunk. check-in: 8b42b8e3 user: mistachkin tags: winSectorSize
18:24
Fix a problem preventing resumption of RBU operations after recovering from a process or system failure that occurs during the incremental-checkpoint phase. check-in: 97914266 user: dan tags: trunk
12:53
Fix the build for SQLITE_ENABLE_MEMORY_MANAGEMENT. check-in: 8c85b8fd user: drh tags: trunk
2017-01-12

Attempt to detect physical sector sizes on Windows Vista and higher. check-in: 6e388423 user: mistachkin tags: winSectorSize
19:10
Remove a branch that is probably unreachable, and which adds no value. check-in: 9acc7238 user: drh tags: trunk
16:21
Fix harmless compiler warnings in the UPDATE code generator. check-in: 385db266 user: drh tags: trunk
16:14

15:19
Test case macros to show that the previous check-in is well tested. Leaf check-in: bd8b977a user: drh tags: extra-testcase-macros
15:11
Improved detection of cells that extend into the reserved space at the end of the page while adjusting overflow page pointers during autovacuum. check-in: 8097712c user: drh tags: trunk
11:52
Remove invalid test case from cursorhints2.test check-in: 163cc1b2 user: drh tags: trunk

Changes to allow some multi-row UPDATE statements to avoid the two-pass approach. check-in: 7ae6104a user: dan tags: trunk
20:10
Fix a problem causing the pre-update hook to be passed an incorrect rowid value in some single-pass multi-row updates. Closed-Leaf check-in: 62257eb5 user: dan tags: onepass-update
19:03
Fix a problem with single-pass multi-row UPDATE statements that invoke REPLACE conflict handling. check-in: 0a2b8e1b user: dan tags: onepass-update
16:52
Attempt to detect physical sector sizes on Windows 8 and higher. check-in: 381fd34b user: mistachkin tags: winSectorSize
15:42
Fix a problem preventing UPDATE statements that use a range-scan on the PK index of a WITHOUT ROWID table from using a one-pass strategy. check-in: cab86c90 user: dan tags: onepass-update
14:15
In the STAT4 computations, ensure that the aAvgEq values do not go negative. check-in: f58f75b5 user: drh tags: trunk
2017-01-10
20:04
Changes to allow some multi-row UPDATE statements to avoid the two-pass approach. check-in: 46db23cc user: dan tags: onepass-update

18:22
Fix typo in a comment. No changes to code. check-in: d38fd229 user: mistachkin tags: trunk
