14:07

2019-01-18

Revamp the SrcList allocator routines to be methods of Parse instead of being methods of the "sqlite3" object, so that they can leave better error messages when the SrcList object grows too large. check-in: df08d472 user: drh tags: trunk
14:34
Limit the size of SrcList objects to 200 entries (compile-time configurable using -DSQLITE_MAX_SRCLIST=n).

2019-01-13
20:23
In dbfuzz2, avoid using a malloc in the LLVMFuzzerInitialize() initializer routine, so that no memory leaks are reported. Also, show the version of SQLite being used when the -v option is on. check-in: 824f9324 user: drh tags: trunk
20:17
Relax the minimum size database file constraint on the dbtotxt utility program. check-in: 97e723d7 user: drh tags: trunk
