| ||
| 15:24 | 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. file: [920285c3] check-in: [1e17ea2f] user: drh branch: omit-stat3, size: 62001 | |
|
2019-07-09

| 23:35 | Add the "LL" suffix on a pair of larger integer literals, for compatibility with older C compilers. file: [f6f277d1] check-in: [6f328c35] user: drh branch: trunk, size: 63623 | |

2019-06-12

| 20:51 | As a special case, casting '-0.0' into numeric should yield 0. Fix for ticket [674385aeba91c774]. file: [9ee3c037] check-in: [491f0f9b] user: drh branch: trunk, size: 63619 | |
|
2019-06-11
| ||

|
2019-06-10
| ||
| 18:33 | 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]. file: [44ef1a12] check-in: [c0c90961] user: drh branch: trunk, size: 63524 | |
|
2019-06-07
| ||
| 22:26 | 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]. file: [be520020] check-in: [67a68af5] user: drh branch: trunk, size: 63609 | |
|
2019-05-29
| ||
| 21:18 | Much faster implementation of applyNumericAffinity() by avoiding some unnecessary calls to sqlite3Atoi64(). file: [5ecfa992] check-in: [c1d8a3f6] user: drh branch: trunk, size: 63520 | |
|
2019-05-16
| ||
| 11:47 | Fix a harmless use-of-initialized-value fault in the assert() logic added by check-in [d612fb7873cf59d] file: [e9a0aa2f] check-in: [3dac9072] user: drh branch: trunk, size: 63527 | |
| 01:22 | 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. file: [14618670] check-in: [d612fb78] user: drh branch: trunk, size: 63527 | |
|
2019-05-04
| ||
| 01:41 | 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. file: [b76b42ac] check-in: [5a8a23ee] user: drh branch: trunk, size: 62937 | |
| 01:29 | New testcase macros to ensure that MEM_IntReal is fully tested. file: [81dc93a8] check-in: [8b8ef445] user: drh branch: int-real, size: 62684 | |
|
2019-05-03
| ||
| 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. file: [42a33c8f] check-in: [3a16ddf9] user: drh branch: trunk, size: 62172 | |
|
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. file: [e102c625] check-in: [dba836e3] user: drh branch: int-real, size: 62267 | |
|
2019-05-01
| ||
| 18:59 | 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. This appears to fix ticket [ae0f637bddc5290b446]. file: [df36fd36] check-in: [5997d075] user: drh branch: trunk, size: 61919 | |

| 15:59 | Change the sqlite3VdbeMemGrow() routine so that it no longer guarantees a minimum size of 32 bytes. That minimum is no longer required, and without the extra check for the minimum size, the routine runs faster. file: [8facf8d2] check-in: [5c499da8] user: drh branch: trunk, size: 61691 | |
