| 14:47 | Change to tcl test infrastructure so that --malloctrace=1 works when sizeof(int)!=sizeof(void*). (check-in: c3e771b3 user: dan tags: experimental) | |
| 07:51 | Fix a problem causing the return code of an xSync call to be ignored in wal.c. (check-in: f1b2b5f9 user: dan tags: experimental) | |
| 07:07 | In WAL mode, ignore any error returned by an xFileControl(FCNTL_SIZE_HINT) call. This matches the behaviour in rollback mode. (check-in: 158a3097 user: dan tags: experimental) | |
