Fix a crash in the sqlite_dbdata module that could occur if a pointer within an overflow chain in a corrupt database pointed past the end of the db. check-in: 3eae4e30 user: dan tags: trunk
17:10
Disable the optimization where a REAL value with no fractional part is stored as an INTEGER when the integer uses as much space as the real value it proposes to stand in for (8 bytes). This avoids corner cases of comparing integers against real values that are beyond the resolution of an IEEE 754 double. Fix for ticket [6c1d3febc00b22d457c78c2] check-in: 9b091527 user: drh tags: trunk

2019-05-08
23:55
Ensure that the sqlite3BtreeLast() interface initializes the *pRes return to zero if the cursor is already sitting on the last entry of the table. Manuel Rigger found the obscure test case for which this makes a difference. check-in: ebe4845c user: drh tags: trunk
23:53
This is part of the previous check-in that didn't get committed for some reason - probably because I failed to press the "Save" button on the text editor. check-in: 51d32173 user: drh tags: trunk
21:14
Add another test case to cover a previously uncovered branch in the RBU module. check-in: 30392985 user: dan tags: trunk

19:32
Simplification to the logic underlying PRAGMA case_sensitive_like. check-in: ef0015fd user: drh tags: trunk

18:49
Add tests to improve code coverage of the RBU module. check-in: ecb56b75 user: dan tags: trunk
17:27

2019-05-07
20:06
Generate all records for INSERT or UPDATE prior to running foreign key constraint checks, since the FK checks might modify the datatype of registers used to generate the records. Fix for ticket [e63cbcfd3378afe6980d6]. check-in: 3c75605b user: drh tags: trunk
19:44

19:34
Ensure that UTF16 strings are properly zero-terminated before returning them in an sqlite3_value_text16() request, even if the string is invalid UTF16 because it was formed from an arbitrary and/or odd-length BLOB. check-in: 3a16ddf9 user: drh tags: trunk

2019-05-02
21:36
Make MEM_IntReal a completely independent type, meaning a floating point value stored as an integer. This fixes a problem with arithmetic within arguments to string functions on indexes of expressions. But it is a big change and needs lots of new testcase() macros for MC/DC and so it is initially put on this branch. check-in: dba836e3 user: drh tags: int-real
17:45
Ensure that the typeof() function always returns SQLITE_FLOAT for floating point values even when the value is stored as an integer to save space. check-in: 48889530 user: drh tags: trunk
17:06

14:15
Merge enhancements from trunk check-in: 3a4751a9 user: drh tags: hard-heap-limit
01:41
The "LIKE Optimization" (which converts a LIKE into a BETWEEN operator that is able to use an index) does not work and cannot be used if the collating sequence of the column is not TEXT and if the pattern starts with a "+" sign. This is another case of ticket [c94369cae9b561b1f996d005]. The new test case was discovered by Manuel Rigger. check-in: b043a54c user: drh tags: trunk

Remove some stale references to the addopcodes.tcl script from documentation. check-in: c0381b0b user: drh tags: trunk
20:56
Eliminate the tool/addopcodes.tcl script. The purpose of that script was to keep the number of parser codes below 256 in order to save parser table space. But we have long since blown through that ceiling so the addopcodes.tcl script was just needless complexity. There is no longer any reason to keep it around. check-in: d2728192 user: drh tags: trunk
20:47
Add further tests so that veryquick.test covers all vdbe branches. check-in: cbc67de5 user: dan tags: trunk
17:22
Improved comment on the sqlite3FaultSim() function. No changes to code. check-in: 08b29672 user: drh tags: trunk
16:52
In the test_vfs.c VFS, if a Tcl xWrite script returns "SQLITE_OMIT", silently omit the write() call. check-in: 8b5a621e 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: e859d318 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: af1e5873 user: drh tags: trunk
2019-04-04
20:55
Add further test cases to improve VDBE branch coverage. check-in: 51a95e52 user: dan tags: trunk
19:21
Fix a typo in the documentation for sqlite3_value_frombind(). Also add a new hyperlink to that same documentation. No code changes. check-in: bf3cd936 user: drh tags: trunk
18:20
Minor fixes to requirements marks. check-in: 02ebc60b user: drh tags: trunk

17:39
Correctly initialize the loadable extension thunk. check-in: 4fca46de user: drh tags: trunk
15:25
Simplification of the recent VACUUM changes that make the code more like what it was before the change. Also, make the VACUUM command a no-inline procedure to work around a performance regression. check-in: 9cac5ac1 user: drh tags: trunk

Small optimizations to the grammar for window functions save about 120 bytes of space in the parser tables. check-in: bce01d95 user: drh tags: trunk
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: bc0fb1c3 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: 10aedce3 user: drh tags: trunk
13:10
Put the list of keywords in mkkeywordhash.c into alphabetical order. check-in: ac98b23b user: drh tags: trunk
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: f7ba2daf user: drh tags: trunk
00:48
Add new APIs to the extension loading mechanism. check-in: 6f122faf user: drh tags: trunk
00:28

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: f0ed7146 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: fa37cf9a user: drh tags: trunk
15:55
Mark rowid-comparison opcodes as never-null for VDBE coverage tracking purposes. check-in: a69bb4f2 user: drh tags: trunk

Improvements to VdbeCoverage macros. check-in: 10ee9e33 user: drh tags: trunk
20:37
Fix issues with the previous check-in and add more VDBE branch coverage testing macros. Closed-Leaf check-in: b5f72f10 user: drh tags: oops
20:10
Enhanced VdbeCoverage() macros in the new windows function code. Later: This check-in causes an assertion fault. check-in: f24066f8 user: drh tags: oops
19:17
Add a call to sqlite3FaultSim(410) inside of btreeRestoreCursorPosition() to simplify testing of error scenarios. check-in: bb643bac user: drh tags: trunk
18:39
The defragmentPage() routine detects corruption in the first-free-slot fields at offset 1 in the header and throws an error, rather than asserting. check-in: fb125bd3 user: drh tags: trunk
17:30
Add the blobio.c extension module implementing readblob() and writeblob(). Experimental. check-in: e3fde56d user: drh tags: trunk

Change the fts3_tokenizer() function to always return the pointer as a BLOB as long as the first argument is a bound parameter, regardless of the SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER setting. check-in: 27160df7 user: drh tags: value_frombind
15:21
Remove the unused P5 flag from the OP_Rewind opcode. check-in: c2edbf3b user: drh tags: trunk
13:17
Fix a fairly obscure problem causing the planner to sometimes choose sub-optimal plans for a query with a single virtual table in the FROM clause, and at least one IN(...) constraint in the WHERE clause. check-in: f5752517 user: dan tags: trunk
11:48
Fix typos in the comments of the sessions extension, one of which affects the generated documentation. No code changes. check-in: 040d5d51 user: drh tags: trunk
11:39
The two-argument version of fts3_tokenizer() works regardless of the value of SQLITE_DBCONFIG_ENABLE_FT3_TOKENIZER as long as the second argument is a bind parameter. check-in: ab76e3a9 user: drh tags: value_frombind
