Fix the SQLITE_DESERIALIZE_READONLY feature so that it does not cause an assertion fault in the pager. check-in: b9eccef7 user: drh tags: trunk
16:11
Update dbfuzz2 to set a maximum database size of 100MiB by default, but with the new --max-db-size N option to change that limit. check-in: 21d6bb78 user: drh tags: trunk

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).

Fix a harmless memory leak in the Lemon parser generator utility program. check-in: 1caff0fb user: drh tags: trunk
14:31
Fix a problem triggered by DELETE statements with WHERE clauses that use the OR-optimization on some virtual tables. check-in: ecf5caa7 user: dan tags: trunk
2019-01-14
20:44
Add scalar function "prefix_length()" to ext/misc/prefixes.c. check-in: 0bf15505 user: dan tags: trunk
19:13
Fix a problem causing some Tcl test cases to fail with errors like "expected: [<multiline-whitespace>], got: []". check-in: 11b8a4cb user: dan tags: trunk
16:16
Add the "prefixes" table-valued function in the ext/misc folder. check-in: f0fd2163 user: drh tags: trunk
15:35
Fix a problem causing a crash if an fts5vocab table was created to query an fts3/4 FTS index. check-in: 9cd64ce4 user: dan tags: trunk
15:09
Fix a problem with querying a corrupt fts3 database. check-in: 65e50706 user: dan tags: trunk
13:32
