| 23:25 | Improve the performance of the built-in REPLACE() function in cases where it does many substitutions that make the string larger. OSSFuzz is reporting intermittant timeouts when running a test where it does a REPLACE() on a 930KB random blob. Perhaps this enhancement will fix that. (check-in: fab2c2b0 user: drh tags: trunk) | |
