| 17:51 | When transfering an error message from a statement handle to the database handle so that it can be accessed by sqlite3_errmsg(), a malloc may fail. If this malloc fails, it is considered benign. (CVS 5806) (check-in: 311003af user: danielk1977 tags: trunk) | |
| 17:42 | Conditionally omit prototypes in pcache.h when the corresponding routines are not used. Ticket #3430. (CVS 5805) (check-in: 977ae12c user: drh tags: trunk) | |
| 17:35 | Fix to sqlite3DbMallocRaw() when SQLITE_OMIT_LOOKASIDE is defined so that once it fails it continues to fail. Add a comment explaining why this is important. (CVS 5804) (check-in: 63dd8be7 user: drh tags: trunk) | |
