Changes In Branch pure-date-functions Excluding Merge-Ins
This is equivalent to a diff from c93284cd65 to 55791928f3
2017-07-19
| ||
18:01 | Remove some 'breakpoint' commands in test files. (check-in: d14fc621e9 user: mistachkin tags: trunk) | |
17:12 | Create "pure" versions of the date/time functions that omit the 'now' feature and are therefore deterministic and usable in an index. (Closed-Leaf check-in: 55791928f3 user: drh tags: pure-date-functions) | |
11:52 | Add further tests to unionvtab.test. (check-in: c93284cd65 user: dan tags: trunk) | |
2017-07-18
| ||
21:19 | Fix a crash in unionvtab caused by a misconfiguration. Add other test cases for the same. (check-in: 255d6b99de user: dan tags: trunk) | |
