| 20:59 | Fix all known instances of signed-integer overflow. Within SQL expressions, integer overflow now forces coercion to floating point. The shift operators work with any integer right-hand operand with negative values reversing the direction of the shift. check-in: abf21394 user: drh tags: trunk | |
| 13:54 | Fix an instance of signed arithmetic overflow and an one bit-shift overflow. Mark six other signed arithmetic overflow locations that need fixing. check-in: 04abab71 user: drh tags: trunk | |

| 14:11 | • Edit [a586a4deeb253300|a586a4de]: Add tag "version-3.7.4". artifact: f422ba09 user: drh | |
| 05:34 | Fix problems in the backport, reducing the number of errors in the TCL tests to just a few dozen. Most of the remaining errors seem to be real and desirable changes of behavior. check-in: 9d2b0af2 user: drh tags: branch-3.7.2 | |
| 01:59 | This is the beginning of an attempt to backport recent query planner enhancements to version 3.7.2. The code in this version builds and runs and seems to give correct answers, but it generates suboptimal query plans and hence many of the test cases fail. The test script gives up after 1000 errors. check-in: e72cf118 user: drh tags: branch-3.7.2 | |

| 06:59 | Fix a bug in the new WHERE-clause processing that tries to use an index to resolve IS NOT NULL constraints when SQLITE_ENABLE_STAT2 is defined. The bug could cause memory overruns and segfaults. The bug was new to the code and has not appeared in an official release. Found during structural testing. check-in: a5c36b9f user: drh tags: trunk | |
| 03:58 | • Edit [d78949fc93077e1a|d78949fc]: Edit check-in comment. artifact: 7d2ceb35 user: drh | |
