| 15:02 | [30c13916] part of check-in [5377add4] Fix the OP_Move opcode so that it correctly manages dependency tracking. This change impacts debugging builds only. (check-in: [5377add4] user: drh branch: trunk, size: 62507) | |
| 14:42 | [e5c0fbad] part of check-in [9886cb4b] Enhancements to aid testing and debugging: In PRAGMA vdbe_trace=on output, show pScopyFrom dependencies on register values. Add the sqlite3VdbeRegisterDump() procedure, callable from a debugger, that shows the values of all registers. Pass the VDBE pointer into test_trace_breakpoint() so that sqlite3VdbeRegisterDump() is callable from the breakpoint. (check-in: [9886cb4b] user: drh branch: trunk, size: 62505) | |

|
2019-12-23
| ||
| 03:37 | [fa083086] part of check-in [f347744e] Fix the OP_Cast operator so that when casting to TEXT, it always leaves the result in the encoding of the database. Ticket [0911b5d161b039c6]. Test cases in TH3. (check-in: [f347744e] user: drh branch: trunk, size: 62147) | |
|
2019-12-03
| ||
| 02:51 | [2eb00a4d] part of check-in [3ce804e9] Avoid computing a zero offset of a null pointer, which though this is technically harmless, is upsetting to pedantic run-time checkers. (check-in: [3ce804e9] user: drh branch: trunk, size: 62075) | |

| ||
| 03:16 | [d8e10d17] part of check-in [3fb40f51] Fix the instr() SQL function so that it makes a copy of its argument before changing the datatype, since the datatype affects processing.

|
2019-08-08
| ||
| 15:24 | [920285c3] part of check-in [1e17ea2f] Remove support for STAT3. The sqlite_stat3 tables are ignored, if they exist. STAT4 continues to work as it always has, and as it is a superset of STAT3 is the recommended replacement. (check-in: [1e17ea2f] user: drh branch: omit-stat3, size: 62001) | |
|
2019-07-09
| ||

| ||
| 20:51 | [9ee3c037] part of check-in [491f0f9b] As a special case, casting '-0.0' into numeric should yield 0. Fix for ticket [674385aeba91c774]. (check-in: [491f0f9b] user: drh branch: trunk, size: 63619) | |

| ||
| 18:33 | [44ef1a12] part of check-in [c0c90961] Make sure a CAST to "NUMERIC" results in an integer if the value can be losslessly expressed as an integer, as the documentation requires. Ticket [dd6bffbfb6e61db9]. (check-in: [c0c90961] user: drh branch: trunk, size: 63524) | |
|
2019-06-07
| ||
| 22:26 | [be520020] part of check-in [67a68af5] When casting string values into numeric and the string has a prefix that looks like a number but total string is not a well-formed number, then take extra care that the result is either integer or real depending on what the prefix looks like. Fix for tickets [e8bedb2a184001] and [4c2d7639f076aa]. (check-in: [67a68af5] user: drh branch: trunk, size: 63609) | |
|

| ||
| 21:18 | [5ecfa992] part of check-in [c1d8a3f6] Much faster implementation of applyNumericAffinity() by avoiding some unnecessary calls to sqlite3Atoi64(). (check-in: [c1d8a3f6] user: drh branch: trunk, size: 63520) | |

| 01:22 | [14618670] part of check-in [d612fb78] Make sure the OP_Concat opcode always correctly zero-terminates a UTF16 string, even if the input strings are ill-formed. This is a followup to check-in [3a16ddf91f0c9c516a7] that fixes a case the previous check-in missed. Also add assert()s to prove correct zero termination. (check-in: [d612fb78] user: drh branch: trunk, size: 63527) | |
|
2019-05-04
| ||
| 01:41 | [b76b42ac] part of check-in [5a8a23ee] In the sqlite3_value or Mem object, make the MEM_IntReal type completely independent from MEM_Int and MEM_Real. This helps avoid problems when inserting non-float values into a "REAL" column. (check-in: [5a8a23ee] user: drh branch: trunk, size: 62937) | |

|
2019-05-02
| ||
| 21:36 | [e102c625] part of check-in [dba836e3] 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 branch: int-real, size: 62267) | |
|
2019-05-01
| ||
| 18:59 | [df36fd36] part of check-in [5997d075] When values have real affinity and are converted into strings for CHECK constraints or index expressions, do the conversions into a real-number format even if the values are stored as integers for efficiency.

| 15:59 | [8facf8d2] part of check-in [5c499da8] Change the sqlite3VdbeMemGrow() routine so that it no longer guarantees a minimum size of 32 bytes.
