| 16:52 | In the test_vfs.c VFS, if a Tcl xWrite script returns "SQLITE_OMIT", silently omit the write() call. check-in: 8b5a621e user: dan tags: trunk | |

| 15:44 | In the xfer-optimization, do early detection of when the source and destination index share the same btree, to avoid a long delay prior to reporting the database corruption. check-in: af1e5873 user: drh tags: trunk | |

| 17:45 | Including the phrase EXCLUDE NO OTHERS in the frame-spec of a window function (which is the default setting for EXCLUDE) silently disables the xInverse optimization.

| 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 | |
| 18:46 | Performance improvement in the parsing of options to %-formats in the printf implementation. check-in: 40d8f8ae user: drh tags: trunk | |

| 16:09 | Remove an incorrect assert() from the deserialize in-memory database VFS. check-in: 80151d7e user: drh tags: trunk | |
| 15:38 | Add the SQLITE_CONFIG_MEMDB_MAXSIZE configuration option for configuring the default maximum size of an in-memory database created using sqlite3_deserialize(). This is necessary to make the interface reasonably testable. check-in: cb72ee04 user: drh tags: trunk | |
| 14:37 | Fix another buffer overrun that could occur when quering a corrupt database using an fts5vocab table. check-in: b80119bd user: dan tags: trunk | |
| 02:42 | 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 | |

| 11:42 | Fix a buffer overrun triggered by a merge operation on a corrupt fts5 database. check-in: 7ee3cd5b user: dan tags: trunk | |
| 02:37 | Set a low limit on the length of strings and blobs in the OSSFuzz module, in an effort to avoid timeouts when the fuzzer does things like "randomblob(1e12)". check-in: 119d1609 user: drh tags: trunk | |
