| 21:34 | Allow non-deterministic function in CHECK constraints. It turns out that PostgreSQL, MySQL, and SQLServer all allow this. We should be the the exception. Ticket [830277d9db6c3ba1] check-in: 8c8ce526 user: drh tags: trunk | |
| 19:58 | Fix a couple of test case issues on this branch. check-in: 9830a44b user: dan tags: reuse-schema | |
| 19:46 | Do not use memcpy() of zero bytes when initializing a pager. This avoids a warning. check-in: cca43778 user: drh tags: trunk | |
| 19:07 | Disable a redundant test case that uses a very large stack, and hence is unable to run with -fsanitize=undefined,address. check-in: 3c63f68e user: drh tags: trunk | |
| 19:02 | Fix harmless compiler warning seen with MSVC. check-in: cd0437ba user: mistachkin tags: trunk | |

2020-01-17
| ||
| 23:27 | Fix a typo in a comment. No code changes. check-in: 4363f69c user: drh tags: trunk | |
| 21:12 | The compress() function should not be deterministic since the same input can have multiple possible compressed outputs. The uncompress() function, on the other hand, is deterministic. check-in: 84f31490 user: drh tags: trunk | |
| 19:14 | Fix #ifdefs so it compiles cleanly with all SQLITE_OMIT compile-time options. Update compile-time option testing. check-in: 7584e4b6 user: drh tags: trunk | |
| 16:47 | Improved rounding in the 'unixepoch' feature of the date and time functions. check-in: c9abf1bd user: drh tags: trunk | |
| 15:45 | Update test script instrfault.test to account for the fact that bound blob values cast to text values are now intepreted using the text encoding of the database, instead of always as utf-8. check-in: 4d6cb288 user: dan tags: trunk | |

| 14:30 | Import the 3.31.0-beta FTS3/4 code directly into the 3.28 branch, thus providing 3.28 with all the latest 3.31 fixes. FTS3 has not been enhanced to use any core functionality that was not already available in 3.23, so no modifications were made to FTS3 sources for this import. check-in: be4269c6 user: drh tags: branch-3.28 | |
| 14:18 | Import all FTS3/4 enhancements and fixes that exist on the latest trunk (3.31.0-beta) that do not require extensive change to the SQLite core into the 3.22 branch. Basically, the 3.31.0 FTS3 sources are copied into 3.22.0, with minor changes to work around core enhancements that are not available in 3.22.0. Leaf check-in: cbcbb1e5 user: drh tags: branch-3.22 | |

| 16:12 | Do not allow the constant-propagation optimization to apple to ON/USING clause terms as it does not help and it might cause downstream problems. check-in: 1bc783da user: drh tags: trunk | |
| 13:02 | Very small performance improvement by ensuring that the argument to sqlite3VdbeFreeCursor() is non-NULL. Hold for the next sprint. Leaf check-in: f8801ffd user: drh tags: close-cursor-faster | |

| 16:20 | Do not allow the "PRAGMA encoding" statement to change the database encoding if TEMP content exists, or content in any other attached database. Formerly, encoding changes were allowed if just the main database file was empty. Ticket [a08879a4a476eea9]. check-in: 03b003c9 user: drh tags: trunk | |
| 14:26 | Merge all recent enhancements and fixes from trunk. check-in: f7839178 user: drh tags: reuse-schema | |

|
2020-01-14
| ||
| 16:50 | Fix the urifuncs.c extension (used for testing and debugging only) so that the sqlite3_filename_database() SQL function and its siblings correctly handle an invalid schema name passed in as the argument. check-in: 3d7434a9 user: drh tags: trunk | |
| 16:39 | Remove an ALWAYS on a branch for improved database corruption detection in btree.c:freeSpace(). Test case found by dbsqlfuzz. check-in: 54bf0481 user: drh tags: trunk | |
| 16:33 | Add the new noop_nd() debugging function to the noop.c extension. check-in: 72911fb1 user: drh tags: trunk | |
| 13:24 | For the showdb utility program, more accurate detection of when the database is in autovacuum mode for the "pgidx" subcommand. check-in: 9ce2192b user: drh tags: trunk | |

| 22:38 | Better than removing the incorrect assert() is to change it into a testcase() together with a comment indicating where an appropriate test case can be found, and the ticket that provoked the change. Ticket [614b25314c766238] check-in: 3e3c60d8 user: drh tags: trunk | |
| 22:25 | Change the zipfile virtual table so that the xBestIndex method gives a reasonable cost estimate even if no filename is specified. The missing filename error continues to be raised in the xFilter method. Meanwhile, the more reasonable cost estimate avoids unnecessary wierdness in the query planner. check-in: 0e468aa6 user: drh tags: trunk | |
| 22:20 | Remove an incorrect assert(). Fix for ticket [614b25314c766238] check-in: 6a999c5a user: drh tags: trunk | |

| ||
| 21:08 | New apis: sqlite3_filename_database(), sqlite3_filename_journal(), and sqlite3_filename_wal(). Also sqlite3_uri_key(). And the other sqlite3_uri functions now work using the journal or wal filename in addition to the database file. And the sqlite3_db_filename() result is guaranteed to work as an argument to the sqlite3_uri functions. check-in: fd7bcc53 user: drh tags: trunk | |
| 20:27 | Minor changes for consistency between sqlite3_filename_wal() and sqlite3_filename_journal(). Closed-Leaf check-in: 9a70ff43 user: drh tags: enhanced-uri | |

|
2020-01-10
| ||
| 18:05 | Rearchitect the way in which filenames are stored in the Pager object so that the sqlite3_uri_parameter() interface will work from journal and WAL filenames too. This check-in implements the central idea, and compile and runs somewhat, but crashes on an extended test. check-in: 2ae77bd2 user: drh tags: enhanced-uri | |
| 01:05 | Fix to the register validity tracking logic in debug builds. No impact on release builds. check-in: 0a500da6 user: drh tags: trunk | |
| 00:20 | Begin making changes to turn off trusted schema in command-line tools that open SQLite databases. There are a lot of these, and a lot of places to change, which makes me wonder if trusted schema should be off by default. Leaf check-in: 3d23a275 user: drh tags: default-untrusted-schema | |
| 00:00 | Documentation updates on newer APIs. No changes to code. check-in: 8845a8c2 user: drh tags: trunk | |

| 20:48 | In the typeof() optimization in OP_Column, expand the size of the bogus buffer provided for data so that it is big enough to cover the increased number of bytes displayed during register tracing from check-in [54553bf16fabd72d]. This is the correct fix for ticket [bbd55a97e66ff50d], though the earlier one does not hurt and is useful to retain. check-in: e1154c39 user: drh tags: trunk | |
| 19:30 | Merge enhancements from trunk. check-in: 9c50f6c2 user: drh tags: new-security-options | |
| 19:23 | Rewrite the (debugging use only) sqlite3VdbeMemPrettyPrint() function to use the safer StrAccum interface rather than writing directly into a static string buffer. Perhaps this will address ticket [bbd55a97e66ff50d], which we are unable to reproduce. check-in: 69f6a7e4 user: drh tags: trunk | |

| 16:38 | Improvement to check-in [7405e98225761180] so that missing or null filenames given to the zipfile extension throw an immediate error. check-in: 523e09bd user: drh tags: trunk | |

| 15:02 | Fix the OP_Move opcode so that it correctly manages dependency tracking. This change impacts debugging builds only. check-in: 5377add4 user: drh tags: trunk | |
| 14:42 | Enhancements to aid testing and debugging: In PRAGMA vdbe_trace=on output, show pScopyFrom dependencies on register values. Add the sqlite3VdbeRegisterDump() procedure, callable from a debugger, that shows the values of all registers. Pass the VDBE pointer into test_trace_breakpoint() so that sqlite3VdbeRegisterDump() is callable from the breakpoint. check-in: 9886cb4b user: drh tags: trunk | |
| 13:26 | Add the test_trace_breakpoint() subroutine that is invoked after each instruction is printed while running PRAGMA vdbe_trace=on. Only works for SQLITE_DEBUG builds. Also add parameters "pc" and "pOp" to test_addop_breakpoint() to make it easier to set conditionals. check-in: 49a6368c user: drh tags: trunk | |

| 15:43 | New test-only SQL functions: implies_nonnull_row(), expr_compare(), and expr_implies_expr(). The SQLITE_TESTCTRL_INTERNAL_FUNCTIONS test-control is modified to toggle internal function access on and off for a single database connection. check-in: 473892a8 user: drh tags: trunk | |

| 16:20 | Disable early coding of transitive constraints at the end of each loop in the WHERE clause processing if the loop being coded is for a LEFT JOIN, even if the loop is part of an OR-clause optimization for virtual tables. Test cases in TH3. check-in: 9421b442 user: drh tags: trunk | |
| 15:24 | Fix an instance where the planner might choose to use the OR-optimization when it adds no benefit. The same quirk causes an assert() to fail.
