| 17:58 | Add test cases to improve coverage of VDBE branches. Still some to go. check-in: 4cef609d user: dan tags: trunk | |
| 17:39 | Correctly initialize the loadable extension thunk. check-in: 4fca46de user: drh tags: trunk | |
| 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: 9cac5ac1 user: drh tags: trunk | |
| 14:36 | Fix an incorrect comment on a test case for rowid renumbering in VACUUM. check-in: 0d293fb4 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: 13a0ea64 user: drh tags: trunk | |

| 18:12 | Small optimizations to the grammar for window functions save about 120 bytes of space in the parser tables. check-in: bce01d95 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: bc0fb1c3 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: 10aedce3 user: drh tags: trunk | |
| 13:10 | Put the list of keywords in mkkeywordhash.c into alphabetical order. check-in: ac98b23b user: drh tags: trunk | |

| 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: f7ba2daf user: drh tags: trunk | |
| 00:48 | Add new APIs to the extension loading mechanism. check-in: 6f122faf user: drh tags: trunk | |

| 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: f0ed7146 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: fa37cf9a user: drh tags: trunk | |
| 15:55 | Mark rowid-comparison opcodes as never-null for VDBE coverage tracking purposes. check-in: a69bb4f2 user: drh tags: trunk | |
| 14:30 | Improved VDBE branch coverage in the run-time frame-spec error detection logic of window functions. check-in: f56d305a 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: f24066f8 user: drh tags: oops | |
| 19:17 | Add a call to sqlite3FaultSim(410) inside of btreeRestoreCursorPosition() to simplify testing of error scenarios. check-in: bb643bac 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: fb125bd3 user: drh tags: trunk | |
| 17:30 | Add the blobio.c extension module implementing readblob() and writeblob(). Experimental. check-in: e3fde56d user: drh tags: trunk | |
| 17:07 | Add an extra IO-error test to windowfault.test. check-in: 5b8c44cd 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: 27160df7 user: drh tags: value_frombind | |
| 15:21 | Remove the unused P5 flag from the OP_Rewind opcode. check-in: c2edbf3b 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: f5752517 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: 040d5d51 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: ab76e3a9 user: drh tags: value_frombind | |
| 11:13 | Initial implementation of the sqlite3_value_frombind() interface. check-in: 98da62df user: drh tags: value_frombind | |

| 13:53 | Show the pointer address for Window objects in the TreeView display. check-in: 1ae70ad2 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: d6a07433 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: ec2f207d 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: 85e53ff1 user: drh tags: trunk | |
| 01:00 | Improvements to the README.md file. No code changes. check-in: bbdbaf84 user: drh tags: trunk | |

| 16:21 | Fix harmless compiler warnings. check-in: a063f7c4 user: drh tags: trunk | |
| 14:04 | Use the mutex-free PRNG in this branch, since anybody using this branch is probably interested in high concurrency. check-in: e88fc6d0 user: drh tags: begin-concurrent | |
| 13:28 | Bring this branch into closer alignment with begin-concurrent. check-in: 6433d366 user: drh tags: begin-concurrent-pnu | |

| 22:05 | Fix an obsolete comment in the CLI. No code changes. check-in: fade103c 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: e775ef00 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: 9b20ee10 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: 24ef3844 user: drh tags: trunk | |
| 19:50 | Earlier detection of corruption while added to the freelist. check-in: 8c80b004 user: drh tags: trunk | |
| 18:44 | Fix a faulty assert() statement in balance_nonroot() - the assert() should use get2byteNotZero() instead of get2byte() for the corner case where the number cells is zero on a 65536-byte page. check-in: bcbe7d96 user: drh tags: trunk | |
| 15:09 | Improvements to the help text in the CLI. check-in: 919fec91 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: f11c8959 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: 191a023a user: drh tags: trunk | |

| 13:56 | Fix a problem with a window function in a correlated sub-query where at least one reference to the outer SELECT appears in a FROM clause sub-select. Closed-Leaf check-in: 9aca86f9 user: dan tags: window-functions | |
| 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: 7a0a26ed user: drh tags: trunk | |
| 11:38 | Add the --limit N option to dbfuzz2. Set the default callback limit to 250K. check-in: b99f8512 user: drh tags: trunk | |
| 01:26 | Sync up the autoconf makefile for MSVC. check-in: ecbae90a user: mistachkin tags: msvcTcl | |

| 17:13 | Disable the feature on this branch in non-SQLITE_ENABLE_SHARED_SCHEMA builds. check-in: b8e53608 user: dan tags: reuse-schema | |
| 13:51 | Remove assert() statements based on the counter-factual proposition that 0 is not a valid cursor number. check-in: c7b33618 user: dan tags: window-functions | |
|
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: 9ef69d18 user: drh tags: apply-affinity-first | |
| 20:02 | Use the IsReuseSchema() macro more consistently. Also, rename it to IsSharedSchema(). check-in: c1be211c user: dan tags: reuse-schema | |
| 19:17 | Fix an error message. check-in: a70fdaa3 user: dan tags: reuse-schema | |

| 16:58 | Fix a potential dangling pointer deference in an ALTER TABLE run on a schema that contains constructs of the form "PRIMARY KEY(column COLLATE collation)". check-in: b9e2393c user: dan tags: trunk | |
| 16:03 | Merge latest trunk changes into this branch. check-in: 4cd20ca6 user: dan tags: reuse-schema | |
| 12:08 | Fix harmless compiler warnings from MSVC. check-in: f0f02d46 user: drh tags: trunk | |
| 11:16 | Enhance the rtreenode() function of rtree (used for testing) so that it uses the newer sqlite3_str object for better performance and improved error reporting. Test cases added to TH3. check-in: 90acdbfc user: drh tags: trunk | |
| 05:45 | Fix various harmless compiler warnings seen with MSVC. Closed-Leaf check-in: 1c0fe5b5 user: mistachkin tags: noWarnings | |
