2019-04-05
16:52
In the test_vfs.c VFS, if a Tcl xWrite script returns "SQLITE_OMIT", silently omit the write() call. check-in: 8b5a621e2e user: dan tags: trunk
16:38
Add the ability to override the new corruption detection logic of the previous checkin, in order to exercise downstream corruption detection during testing. check-in: e859d31846 user: drh tags: trunk
15:44
In the xfer-optimization, do early detection of when the source and destination index share the same btree, to avoid a long delay prior to reporting the database corruption. check-in: af1e5873d4 user: drh tags: trunk
2019-04-04

18:20
Minor fixes to requirements marks. check-in: 02ebc60b9b user: drh tags: trunk
17:58
Add test cases to improve coverage of VDBE branches. Still some to go. check-in: 4cef609d61 user: dan tags: trunk
17:39
Correctly initialize the loadable extension thunk. check-in: 4fca46ded7 user: drh tags: trunk
15:25

14:36
Fix an incorrect comment on a test case for rowid renumbering in VACUUM. check-in: 0d293fb43f user: drh tags: trunk
14:00
Only preserve rowid values for VACUUM INTO. Keep the legacy behavior of renumbering rowids for ordinary VACUUM. check-in: 13a0ea6466 user: drh tags: trunk
2019-04-03
17:54

17:45
Use a separate bit on db->dbOptFlags to disable the xInverse optimization on window functions, rather than reusing the query-flattener disable bit. check-in: bc0fb1c324 user: drh tags: trunk
17:45
Including the phrase EXCLUDE NO OTHERS in the frame-spec of a window function (which is the default setting for EXCLUDE) silently disables the xInverse optimization. This is a feature, but we will keep it undocumented for now in case we later decide it is a bad idea. check-in: 10aedce3dd user: drh tags: trunk
13:10

00:56
Make sure the MEM_FromBind bit inthe Mem.flags field is not included in the MEM_TypeMask. This critical changes was omitted from the previous two check-ins by mistake, and so those check-ins are not fully functional. check-in: f7ba2daf91 user: drh tags: trunk
00:48

Performance improvement on the OP_Variable opcode. Closed-Leaf check-in: 1dc7993bb6 user: drh tags: value_frombind
19:42
Improvements to the sqlite3ExprImpliesNonNullRow() theorem prover. check-in: 3fde627616 user: drh tags: trunk

17:24
If the library is built with SQLITE_VDBE_COVERAGE defined, have the Tcl tests generate a vdbe coverage report in file testdir/vdbe_coverage.txt. check-in: f0ed714637 user: dan tags: trunk
16:23
Frame range comparisons can never be NULL because the values will have been checked for NULL prior to the test. check-in: fa37cf9a6a user: drh tags: trunk

2019-03-31
21:09
Early detection of too many columns in an index avoid a possible 16-bit signed integer overflow. check-in: 8af0caeb6d user: drh tags: trunk
