| 16:56 | Add function sqlite3OsFileControlNoFail(), which is the same as sqlite3OsFileControl() except that it does not simulate OOM errors. This saves adding calls to the BenignMalloc() functions around each of the invocations of sqliteOsFileControl() that ignore the return code. check-in: af59b182 user: dan tags: trunk | |
| 16:40 | Check the return code from sqlite3OsFileControl() in sqlite3BtreeCopyFile() and report any errors that it generates. check-in: 7f852ac6 user: drh tags: trunk | |
| 00:24 | Remove the BenignMalloc() from around the call to FCNTL_OVERWRITE. Add new ones around sqlite3OsDelete(). Fix an assert that causes problems for the nx-devkit. check-in: 38bc4236 user: drh tags: trunk | |
