| ||
| 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.

| ||
| 21:17 | Remove some stale references to the addopcodes.tcl script from documentation. (check-in: c0381b0bc9 user: drh tags: trunk) | |
| 20:56 | Eliminate the tool/addopcodes.tcl script. The purpose of that script was to keep the number of parser codes below 256 in order to save parser table space. But we have long since blown through that ceiling so the addopcodes.tcl script was just needless complexity. There is no longer any reason to keep it around. (check-in: d272819298 user: drh tags: trunk) | |
| 20:47 | Add further tests so that veryquick.test covers all vdbe branches. (check-in: cbc67de5a3 user: dan tags: trunk) | |

|
2019-04-04
| ||
| 22:05 | Add the vtab enable/disable options to the sqlite3_db_config TCL command in the testfixture. (Leaf check-in: c70524280f user: drh tags: disable-vtab) | |

| 15:25 | Simplification of the recent VACUUM changes that make the code more like what it was before the change. Also, make the VACUUM command a no-inline procedure to work around a performance regression. (check-in: 9cac5ac145 user: drh tags: trunk) | |
| 14:36 | Fix an incorrect comment on a test case for rowid renumbering in VACUUM. (check-in: 0d293fb43f user: drh tags: trunk) | |
| 14:00 | Only preserve rowid values for VACUUM INTO. Keep the legacy behavior of renumbering rowids for ordinary VACUUM. (check-in: 13a0ea6466 user: drh tags: trunk) | |
|
2019-04-03
| ||
| 17:54 | Add a defense-in-depth NEVER() test to the WAL cleanup code. (Leaf check-in: 1109942a50 user: drh tags: branch-3.27) | |

| ||
| 18:12 | Small optimizations to the grammar for window functions save about 120 bytes of space in the parser tables. (check-in: bce01d9584 user: drh tags: trunk) | |
| 17:45 | Use a separate bit on db->dbOptFlags to disable the xInverse optimization on window functions, rather than reusing the query-flattener disable bit. (check-in: bc0fb1c324 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. This is a feature, but we will keep it undocumented for now in case we later decide it is a bad idea. (check-in: 10aedce3dd user: drh tags: trunk) | |
| 13:10 | Put the list of keywords in mkkeywordhash.c into alphabetical order. (check-in: ac98b23b34 user: drh tags: trunk) | |
| 01:00 | Merge fixes from trunk. (check-in: 20372906cb user: drh tags: apple-osx) | |
| 00:56 | Make sure the MEM_FromBind bit inthe Mem.flags field is not included in the MEM_TypeMask. This critical changes was omitted from the previous two check-ins by mistake, and so those check-ins are not fully functional. (check-in: f7ba2daf91 user: drh tags: trunk) | |
| 00:48 | Add new APIs to the extension loading mechanism. (check-in: 6f122faf8a user: drh tags: trunk) | |
| 00:34 | Merge enhancements from trunk. (check-in: 0b35aebbb3 user: drh tags: apple-osx) | |

| 17:24 | If the library is built with SQLITE_VDBE_COVERAGE defined, have the Tcl tests generate a vdbe coverage report in file testdir/vdbe_coverage.txt. (check-in: f0ed714637 user: dan tags: trunk) | |
| 16:23 | Frame range comparisons can never be NULL because the values will have been checked for NULL prior to the test. (check-in: fa37cf9a6a user: drh tags: trunk) | |
| 15:55 | Mark rowid-comparison opcodes as never-null for VDBE coverage tracking purposes. (check-in: a69bb4f257 user: drh tags: trunk) | |

| 20:10 | Enhanced VdbeCoverage() macros in the new windows function code. Later: This check-in causes an assertion fault. (check-in: f24066f8dd user: drh tags: oops) | |
| 19:17 | Add a call to sqlite3FaultSim(410) inside of btreeRestoreCursorPosition() to simplify testing of error scenarios. (check-in: bb643bac53 user: drh tags: trunk) | |
| 18:39 | The defragmentPage() routine detects corruption in the first-free-slot fields at offset 1 in the header and throws an error, rather than asserting. (check-in: fb125bd338 user: drh tags: trunk) | |
| 17:30 | Add the blobio.c extension module implementing readblob() and writeblob(). Experimental. (check-in: e3fde56da4 user: drh tags: trunk) | |
| 17:07 | Add an extra IO-error test to windowfault.test. (check-in: 5b8c44cd39 user: dan tags: trunk) | |
|
2019-03-29
| ||
| 17:26 | Change the fts3_tokenizer() function to always return the pointer as a BLOB as long as the first argument is a bound parameter, regardless of the SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER setting. (check-in: 27160df7b3 user: drh tags: value_frombind) | |
| 15:21 | Remove the unused P5 flag from the OP_Rewind opcode. (check-in: c2edbf3b8c user: drh tags: trunk) | |
| 13:17 | Fix a fairly obscure problem causing the planner to sometimes choose sub-optimal plans for a query with a single virtual table in the FROM clause, and at least one IN(...) constraint in the WHERE clause. (check-in: f5752517f5 user: dan tags: trunk) | |
| 11:48 | Fix typos in the comments of the sessions extension, one of which affects the generated documentation. No code changes. (check-in: 040d5d515b user: drh tags: trunk) | |
| 11:39 | The two-argument version of fts3_tokenizer() works regardless of the value of SQLITE_DBCONFIG_ENABLE_FT3_TOKENIZER as long as the second argument is a bind parameter. (check-in: ab76e3a90e user: drh tags: value_frombind) | |

| 13:53 | Show the pointer address for Window objects in the TreeView display. (check-in: 1ae70ad2ff user: drh tags: trunk) | |
| 13:35 | More improvements to TreeView output for Window objects: (1) Show when the frame-spec is implied rather than explicit. (2) Move the FILTER clause out from within the OVER clause, making it a sibling of the OVER clause, to match syntax. (check-in: d6a0743342 user: drh tags: trunk) | |
| 13:03 | Improved TreeView display of Window objects. Change the Window.eType field to Window.eFrmType to avoid confusion with other "eType" values. (check-in: ec2f207ded user: drh tags: trunk) | |
| 04:03 | If the string formatter in sqlite3NestedParse() fails due to an over-length string, make sure this error is recorded by the parser so that it knows to fail. (check-in: 85e53ff133 user: drh tags: trunk) | |

| 16:21 | Fix harmless compiler warnings. (check-in: a063f7c426 user: drh tags: trunk) | |

| 22:05 | Fix an obsolete comment in the CLI. No code changes. (check-in: fade103cba user: drh tags: trunk) | |
| 21:56 | In the CLI, code the "sqlite_parameters" name directly rather than using a macro, for clarity of presentation for users who are reading the code for the purpose of seeing how the CLI implements parameter binding. (check-in: e775ef002d user: drh tags: trunk) | |
| 21:55 | Remove a test from the index build logic which is no longer needed and is in fact unreachable. (check-in: 9b20ee10ff user: drh tags: trunk) | |
| 21:35 | Change the name of the parameter table in the CLI to "sqlite_parameters". Doing so involves adding SQLITE_DBCONFIG_WRITABLE_SCHEMA and allowing the creation of tables whose names begin with "sqlite_" and that are indexed while writable_schema is on. (check-in: 24ef384469 user: drh tags: trunk) | |
| 19:50 | Earlier detection of corruption while added to the freelist. (check-in: 8c80b004ca user: drh tags: trunk) | |

| 15:09 | Improvements to the help text in the CLI. (check-in: 919fec91da user: drh tags: trunk) | |
| 15:06 | Fix the writefile() SQL function implemented by ext/misc/fileio.c such that any directories created have standard umask permissions, not permissions of the file that is to be written. (check-in: f11c89595d user: drh tags: trunk) | |
| 14:24 | For the ".archive --update" command in the CLI, only update files if their mtime or mode has changed. To force an update, use the new --insert instead. (check-in: 191a023ae7 user: drh tags: trunk) | |

| 13:53 | We learn that readdir_r() is deprecated in favor of plain old readdir(), which is now suppose to be threadsafe using thread-local storage. So remove the use of readdir_r() from the test code. (SQLite itself never calls readdir() or readdir_r()). (check-in: 7a0a26ed38 user: drh tags: trunk) | |
| 11:38 | Add the --limit N option to dbfuzz2. Set the default callback limit to 250K. (check-in: b99f8512c0 user: drh tags: trunk) | |

2019-03-20
| ||
| 20:27 | Experimental change to apply affinity before running CHECK constraints on an INSERT. Note that in the CHECK constraints, REAL affinity really is REAL affinity, and not numeric affinity. This causes failures in some tests that are assuming affinity is applied after CHECK constraints. (Leaf check-in: 9ef69d1839 user: drh tags: apply-affinity-first) | |
