| 23:52 | Fix the handling of "PRAGMA count_changes=ON" with UPSERT. Also improved the implementation of count_changes in other places, without changing the behavior. check-in: c6f71115 user: drh tags: trunk | |
| 21:29 | Minor simplification to the upsert logic. check-in: e657c1d6 user: drh tags: trunk | |
| 20:06 | Modify a test case in zipfile2.test to take into account that with some platform/file-system combinations it is possible to fopen() and fread() (but not fwrite()) a directory. check-in: 893e6089 user: dan tags: trunk | |
