| 17:05 | Add new interfaces sqlite3_result_pointer(), and sqlite3_value_pointer() and use them to transfer the eponymous FTS3 column pointer to the snippet() and offsets() routines. Cherrypick from commit [8201f4e1] on branch-3.18. check-in: 553a923c user: dan tags: branch-3.19 | |
| 16:03 | Add interfaces sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer() used to safely move pointer values through SQL without exposing underlying memory address information.

| 16:46 | Enable the ".wheretrace" and ".selecttrace" options in the shell when configure is run using --enable-debug. This mirrors a similar change that has already occurred on trunk. Leaf check-in: c4f798b2 user: drh tags: branch-3.9.2 | |
| 08:14 | In SQLITE_ENABLE_BATCH_ATOMIC_WRITE builds on F2FS file-systems, invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE if an SQLITE_FCNTL_COMMIT_ATOMIC_WRITE call fails. Also, do not use an atomic transaction to create the initial database. This is because if an error occurs while writing to the db file, any changes to the file-size do not seem to be rolled back automatically. The only time this matters is when the file was 0 bytes in size to start with. Cherrypick of [b3122db154]. check-in: 22a228ed user: dan tags: branch-3.19 | |

| 01:28 | Add support for the "memdb" VFS and the sqlite3_memdb_ptr() and sqlite3_memdb_config() interfaces, to enable an SQLite database to be manipulated as an in-memory object. check-in: fb2ac2d2 user: drh tags: memdb | |

| 22:09 | The output of sqlite3_trace() now shows each command of a trigger as it is evaluated. This feature involved major changes to the parser, such as removing the ExprSpan object and replacing it with a new mechanism for capturing the original SQL text of phrases in the input SQL. check-in: 0fdf97ef user: drh tags: trunk | |

| 18:19 | Enhance the Lemon parser generator so that it creates a faster parser at the cost of slightly larger parser tables. Add the ability to measure coverage of the generated state machine when compiling with the -DYYCONVERGE option. In SQLite, add the SQLITE_TESTCTRL_PARSER_COVERAGE test-control to query the new parser coverage feature. check-in: 1b22b42e user: drh tags: trunk | |
| 17:36 | The previous check-in had an error in the coverage reporting logic. Closed-Leaf check-in: ec9b19eb user: drh tags: lemon-improvements | |
| 17:14 | Change the coverage measurement logic in the lemon-generated parser so that it only checks for coverage of state/lookahead pairs that are valid syntax. It turns out that some states are unreachable if the lookahead is not valid syntax, because the states are only reachable through a shift following a reduce, and the reduce does not happen if the lookahead is a syntax error. check-in: 9dce4650 user: drh tags: lemon-improvements | |

| 04:15 | Enhance LEMON so that it generates the action table in such a way that no range check is needed on the lookahead table to verify that the next input token is valid. This makes the lookahead table slightly larger (about 120 bytes) but helps the parser to run faster. check-in: 7eb0198d user: drh tags: lemon-improvements | |

| 11:51 | Add a SELECTTRACE() macro to indicate when column names are assigned to a SELECT statement. This helps with debugging for tickets like [de3403bf5ae5f72e] and [3b4450072511e621]. check-in: 8f194008 user: drh tags: trunk | |

| 20:20 | Add an experimental location(X) SQL function that attempt to return the location of the payload within the database for the record that contains column X. location(X) returns NULL if X is not an ordinary table column or if SQLite cannot figure out the location because it is using a covering index. check-in: 51be9558 user: drh tags: location-function | |
| 19:36 | Add the sqlite3_vtab_collation() function, which allows an xBestIndex callback to determine the collation sequence that SQLite will use for a comparison. And the SQLITE_DBCONFIG_FULL_EQP configuration option, which enhances the output of "EXPLAIN QUERY PLAN" so that it includes statements run by triggers.
