14:07

18:34
In the pager, avoid checking for the illegal page number 0 except when creating a new page. Closed-Leaf check-in: dee20ba9 user: drh tags: pager-get-method
16:57
Fix a problem causing SQLite to return false "foreign key violation" errors when there is a partial (i.e. WHERE constrained) UNIQUE index on the parent key columns. This bug did not cause SQLite to allow illegal data to be inserted into the database, only to reject legal operations. check-in: 850877d1 user: dan tags: trunk
15:53
Further refinements to the virtual method implementation of sqlite3PagerGet(). check-in: 67df4446 user: drh tags: pager-get-method
14:32
Make the sqlite3PagerGet() interface into a virtual method, with different implementations based on the current state of the pager. This gives a small performance increase by avoiding unnecessary branches inside the various methods. check-in: df5bb90d user: drh tags: pager-get-method
2016-12-12
23:24

2016-12-10
13:12
Avoid an unnecessary memset() in the sqlite3BtreeInsert() routine. check-in: 35ecd4eb user: drh tags: trunk
12:58
Reorder the fields in the VdbeCursor object so that those that need to be bulk zeroed on allocation are grouped at the beginning, and the memset() only runs over those fields that really need it. check-in: 8165f88b user: drh tags: trunk
04:06
Avoid signed integer overflow when dealing with a LIMIT and OFFSET whose sum exceeds the maximum integer value. check-in: c9bdf7ad user: drh tags: trunk
00:14
In balance_nonroot, try to combine dropCell/insertCell combinations for the dividers into a cell overwrites. This results in a very small (0.05%) performance gain which is probably not worth the added complexity. Closed-Leaf check-in: 478627c9 user: drh tags: failed-dropCell-opt
2016-12-09
19:42
When doing the sqlite3BtreeInsert() overwrite optimization, make sure the memcpy() does not extend off the end of the page. check-in: 684ef458 user: drh tags: trunk
18:09
Additional comments and an assert on the sqlite3BtreeInsert() overwrite optimization. check-in: c1f0ae9d user: drh tags: trunk
17:32
In sqlite3BtreeInsert() when replacing a re-existing row, try to overwrite the cell directly rather than deallocate and reallocate the cell. check-in: 0b86fbca user: drh tags: trunk
16:12
Fix an fts5 bug that could cause a crash following an OOM error or sqlite3_interrupt() interrupt. check-in: 0ea3ece9 user: dan tags: trunk
16:02
Avoid unnecessary zeroing of fields in the MemPage object that are going to be reinitialized before use anyhow. A smaller and faster binary results. check-in: 01ada3d1 user: drh tags: trunk
00:15
Fix an obscure problem in range estimation with STAT4. check-in: 1f16c9a7 user: drh tags: trunk
2016-12-08

19:04
Fix a minor error in the cg_anno.tcl script causing the cycles-per-file counts to be miscomputed. check-in: b26df26e user: drh tags: trunk

15:49
Rename the SQLITE_OMIT_BUILTIN_TEST compile-time option to SQLITE_UNTESTABLE. check-in: f3608187 user: drh tags: trunk
15:38
Prevent the flattening or where-term push-down optimizations from obscuring misuses of SQL row values that can lead to crashes or assert() failures. check-in: 433d16ff user: dan tags: trunk
13:49
Always honor the sqlite3.dbOptFlags bitmask, regardless of compile-time options. Continuing fix for ticket [da78413751863]. check-in: afab1663 user: drh tags: trunk

00:48
Further changes to the date/time functions to suppress harmless signed integer overflow warnings that could have occurred when doing out-of-range date calculations which, according to the docs, give undefined results. check-in: dc453b34 user: drh tags: trunk
2016-11-29
20:39
The documentation says that the built-in date-time functions give undefined results for dates before 0000-01-01 and after 9999-12-31.
