21:08
Slight adjustment to the printf formatter large memory allocation detector so that it does not overestimate the amount of space needed for oversize %d conversions. (check-in: 1aee70d6 user: drh tags: trunk)
20:29
Prevent the printf formatter from doing large memory allocations - larger than either the size of the static buffer for interfaces like sqlite3_snprintf(), or larger than SQLITE_LIMIT_LENGTH for interfaces that are associated with a database connection. This helps to prevent DOS attacks on products that let hostile sources inject arbitrary SQL. It also helps fuzzers run faster and more effectively. (check-in: 179e5d46 user: drh tags: trunk)

If the amalgamation file "sqlite3.c" is generated using the SQLITE_ENABLE_UPDATE_DELETE_LIMIT option, but then subsequently (mis-)compiled without that option, and then a particular syntax error could cause a memory leak, but for this fix. (check-in: 1bb17c86 user: drh tags: trunk)
01:39
Improvements to "PRAGMA parser_trace=ON": Make it a flag pragma, and then use the flag to show the complete SQL text at the beginning of the parse. (check-in: 507c4353 user: drh tags: trunk)
2019-01-30
19:50

16:58
Fix an off-by-one error when parsing the names of indexes that do not have arguments in the index_usage utility. (check-in: dc794d8f user: drh tags: trunk)

Improvements to the ".eqp trace" command in the CLI so that it ensures that the schema has been read prior to activing the tracing feature, to avoid cluttering the output with a trace of the schema parse. (check-in: 42687d45 user: drh tags: trunk)
02:45
New test cases form dbsqlfuzz (check-in: 9cf8ebd1 user: drh tags: trunk)

Stricter enforcement of cell sizes when doing balancing operations on the btree, in order to catch file corruption sooner. (check-in: 12713f32 user: drh tags: trunk)
19:17
Fix another fts5 crash that can occur if the database is corrupted. (check-in: 44ce8baa user: dan tags: trunk)

16:44
Use _strdup() instead of strdup() on Windows builds of the CLI, to avoid a compiler warning reported on the mailing list. (check-in: a7126a4f user: drh tags: trunk)
16:43
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)
16:06
Enhancements to deserialize: (1) Add the SQLITE_FCNTL_SIZE_LIMIT file control to set a maximum size for an in-memory database, defaulting to SQLITE_MEMDB_DEFAULT_MAXSIZE or 1GiB.

14:34
Limit the size of SrcList objects to 200 entries (compile-time configurable using -DSQLITE_MAX_SRCLIST=n).
