| 12:36 | One possible fix for the [e39d032577d] problem it to replace the failing assert() with a testcase() as shown here. (Closed-Leaf check-in: eae6dfbe55 user: drh tags: tkt-e39d0325) | |
| 12:17 | Fix an unnecessarily obtuse use of a bitmask flag. (check-in: ca31408131 user: drh tags: trunk) | |
| 09:42 | Add a test to ensure os_unix.c works with 64KiB OS pages. (Closed-Leaf check-in: e3d2be3ba4 user: dan tags: shm-mapping-fix) | |
| 08:59 | Add an experimental fix to avoid attempting to mmap memory from an offset that is not a multiple of the system page size on systems with page sizes larger than 32KB. (check-in: 6f3a5c24d2 user: dan tags: shm-mapping-fix) | |

| 23:42 | Merge the vdbesort.c optimization from trunk. (check-in: e4bfffb988 user: drh tags: orderby-planning) | |
| 23:24 | Fix query planner weights associated with choosing block-sorting. Fix block sorting of tables with collating functions. Fix various test cases. All "veryquick" tests are now passing, though more tests need to be added. (check-in: 01afbf97c0 user: drh tags: orderby-planning) | |
| 20:01 | Avoid some unnecessary calls to sqlite3VdbeRecordUnpack() that were being made when merging data from two or more temp files together in vdbesort.c (check-in: 707ea170b3 user: dan tags: trunk) | |
| 17:41 | Make it possible for block-sort to use the OP_SorterOpen sorter in addition to a generic OP_OpenEphemeral. (check-in: 7ce2daafd3 user: drh tags: orderby-planning) | |
| 16:56 | Fix a problem in the block-sort logic that can arise if the VDBE opcode array is resized while the block-sort logic is being coded. "make test" now runs to completion, though there are still 17 failures. (check-in: 62f3a22050 user: drh tags: orderby-planning) | |
| 15:17 | Avoid reusing temporary registers in co-routines when doing block-sorting. (check-in: 463d921b51 user: drh tags: orderby-planning) | |
| 14:30 | Make sure the where.c query planner never reports that the number of ORDER BY terms that are satisfied by indices is negative. (check-in: b186d8d15a user: drh tags: orderby-planning) | |
| 14:10 | First attempt at getting block-sort to work. This is an incremental check-in. There are many problems still to be worked out. (check-in: 59742dd4c5 user: drh tags: orderby-planning) | |
|
2014-03-18

| 20:33 | Make the partial-ORDER-BY information in the query planner available to the SELECT code generator. Still doesn't make a difference in the generated code. (check-in: e258df236b user: drh tags: orderby-planning) | |
| 18:59 | Adjust the query planner to keep track of the number of ORDER BY terms satisfied. Still doesn't do anything with this information. Some tests fail after this check-in, but all failures are believed to be benign. The failures will be addressed at a later stage. (check-in: 59d49b7fc4 user: drh tags: orderby-planning) | |
| 15:30 | Experiments with the optimization of ORDER BY and GROUP BY clauses. (check-in: b150902579 user: drh tags: orderby-planning) | |
|
2014-03-17
| ||
| 15:43 | Add an experimental multi-threaded capability to vdbesorter.c. (check-in: ff0b5c851b user: dan tags: threads) | |
| 15:06 | Clean up some obsolete "register" declarations in printf.c. (check-in: ecd9d3f945 user: drh tags: trunk) | |
| 14:24 | Performance enhancements and size reduction for sqlite3VXPrintf() (check-in: eb071eb58c user: drh tags: trunk) | |

|
2014-03-12
| ||
| 19:38 | Fix an obscure bug causing sqlite3_close() to fail if there are virtual tables on the disconnect list when it is called. (check-in: 6504aa47a8 user: dan tags: trunk) | |
| 19:20 | Changes to FTS to ensure that it does not access the database from within the xConnect method. (check-in: c67a52c356 user: dan tags: trunk) | |
| 12:44 | Prevent the rtree module from reading sqlite_stat1 data from the wrong database. (check-in: 7ce03c1b55 user: dan tags: trunk) | |
| 10:03 | Bump the version number to 3.8.4.1., to conform with trunk. (check-in: 42c9d8fc5f user: drh tags: sessions) | |
|
2014-03-11
| ||
| 23:44 | Remove a stray C99-style comment. (check-in: f500e87d6e user: drh tags: overflow-pgno-cache) | |
| 23:40 | Combine the various boolean fields of the BtCursor object into a single bit-vector. This allows setting or clearing more than one boolean at a time and makes the overflow-pgno-cache branch faster than trunk on speedtest1. (check-in: 968fec44d7 user: drh tags: overflow-pgno-cache) | |
| 20:33 | Enable the b-tree cursor object's overflow page-number cache, which is normally enabled only for incr-blob cursors, for all cursors. (check-in: da59198505 user: dan tags: overflow-pgno-cache) | |
| 15:27 | Version 3.8.4.1 (check-in: 018d317b12 user: drh tags: trunk, release, version-3.8.4.1) | |
| 15:25 | Update version number to 3.8.4.1 (check-in: 33f5694fa4 user: drh tags: trunk) | |
| 14:44 | Forgot to change the VERSION file. (Closed-Leaf check-in: 04caffcef3 user: drh tags: mistake) | |
| 09:19 | Add a test to see what happens if an rtree constructor encounters an SQLITE_BUSY error. No changes to code. (check-in: 5527e23636 user: dan tags: trunk) | |
| 01:48 | Version 3.8.4 for sessions (plus two minor fixes). (check-in: 917c410808 user: drh tags: sessions) | |
|
2014-03-10
| ||
| 20:12 | Adjustments to the cost computation for the skip-scan query plan, to take into account the fact that a seek has to occur on each skip. (check-in: 0769eebd02 user: drh tags: trunk) | |
| 18:03 | Attempt to work around MSVC's treatment of __LINE__ as a non-constant value in "Edit and Continue" mode by avoiding the use of __LINE__ when SQLITE_VDBE_COVERAGE is not defined. (check-in: 0a5318bc27 user: drh tags: trunk) | |
| 12:20 | Version 3.8.4 (check-in: 530a1ee7dc user: drh tags: trunk, release, version-3.8.4) | |

|
2014-03-07
| ||
| 14:57 | Improved comment on the pager.c PERSIST rollback journal delete logic inside of hasHotJournal(). No changes to code. (check-in: e5b17a9d07 user: drh tags: trunk) | |
| 14:36 | Merge the fix for the journal_mode=PERSIST error recovery delay bug. (check-in: bb6a75f4bb user: drh tags: sessions) | |
| 03:31 | Revise change from the previous check-in to clarify the situation when handling open journal files, regardless of journal mode. (check-in: 1c318ef3b7 user: mistachkin tags: trunk) | |
| 02:29 | Avoid calling sqlite3OsDelete() on a file that is open, since this causes Windows to run *very* slowly. Comes up on error recovery in journal_mode=PERSIST. (check-in: fdc651e2ec user: mistachkin tags: trunk) | |
|
2014-03-06

| 18:16 | Do not run corruptH.test in mmap mode. (check-in: c0d54b4e41 user: dan tags: trunk) | |
| 15:01 | Fix a harmless compiler warning in the sessions test harness. (check-in: d389e20ab0 user: drh tags: sessions) | |
| 14:53 | Enhance the test harness for the sessions interface so that it does not use SQLite operations that can encounter an OOM error in places where it is unable to report an OOM error back up to the test script. (check-in: bc0e661033 user: drh tags: sessions) | |
| 13:48 | Merge the latest 3.8.4 tweaks from trunk. (check-in: 1ed463d918 user: drh tags: sessions) | |
| 13:38 | Improved EXPLAIN indentation of a loop in the ANALYZE logic for STAT4. Mark the not-found jump of a seek operation in that loop as never taken. (check-in: 0a4200f95c user: drh tags: trunk) | |
| 12:36 | Remove a branch that is never taken from where.c. (check-in: 4a4997221f user: dan tags: trunk) | |
| 02:15 | Cosmetic change to the shell in-memory database warning to skip coloring the trailing period. (check-in: c87d8e07ec user: mistachkin tags: trunk) | |
| 01:56 | Fix some incorrect comments and typos in comments. Add testcase() macros to some of the new record comparison code. (check-in: b83cfe899d user: drh tags: trunk) | |
| 00:30 | Better loadable extension handling in the Win32 VFS when compiled for Cygwin. (check-in: 29b0a4f158 user: mistachkin tags: trunk) | |
|
2014-02-24

2014-02-20
| ||
| 19:42 | Fix the text of a comment used to generate VDBE opcode documentation so that it omits symbols that can be mistaken for a hyperlink by the parser. (check-in: b46d4e8923 user: drh tags: trunk) | |
| 19:32 | Fix a harmless shadowed-variable warning. (check-in: 824029090d user: drh tags: trunk) | |
| 19:23 | Make sure that the difference between two string pointers is passed into sqlite3_mprintf() as type "int". (check-in: d5d973fedc user: drh tags: trunk) | |
|
2014-02-19
| ||
| 19:14 | Add the VdbeCoverageNeverTaken() macro, and comments that better describe how the VDBE branch coverage measurement works. Add some tags to provide 100% VDBE branch coverage. (check-in: c1e94169dd user: drh tags: trunk) | |
| 14:20 | Add the SQLITE_NOTNULL P5 code for comparison operations - really a composite of SQLITE_NULLEQ and SQLITE_JUMPIFNULL. This flag indicates that NULL operands are not possible and raises and assert() if NULL operands are seen. Also omit an unnecessary scan of the sqlite_sequence table when writing into an AUTOINCREMENT table. (check-in: d2c047f304 user: drh tags: trunk) | |
| 01:31 | Make sure a multi-row VALUES clause works correctly in a compound SELECT. (check-in: 85b355cfb4 user: drh tags: trunk) | |

| 11:31 | Fix VDBE branch accounting on comparison operators. (check-in: b287520c92 user: drh tags: trunk) | |
| 03:07 | Add VdbeCoverage() and VdbeCoverageIf() macros for improved VDBE coverage testing. (check-in: b92d31a97d user: drh tags: trunk) | |
| 01:07 | Improvements to "NOT IN (SELECT ...)" processing. Only test for NULL values on the RHS on the first iteration, then remember the result. There has been logic to do this for year, but it didn't work right and ended up repeating the NULL test on every iteration. This inefficiency was found using the VDBE coverage testing tools. (check-in: 915f6f1c7a user: drh tags: trunk) | |
|
2014-02-17
| ||
| 23:52 | Merge in performance enhancements for INSERT operations, especially INSERTs on tables that have no affinity columns or that have many indices or INSERTs with content coming from a SELECT. Add the SQLITE_TESTCTRL_VDBE_COVERAGE test control and the SQLITE_VDBE_COVERAGE compile-time option used for measure coverage of branches in VDBE programs. (check-in: a72687699b user: drh tags: trunk) | |
| 22:40 | Add logic to do test coverage measurements on the VDBE code. (Closed-Leaf check-in: ce184c7bb1 user: drh tags: insert-optimization) | |
| 15:40 | Add a test case for OP_SoftNull. (check-in: f29d194e03 user: drh tags: insert-optimization) | |
| 15:36 | Merge the VDBE_PROFILE fixes from trunk. (check-in: 2914e41911 user: drh tags: insert-optimization) | |
| 14:59 | Avoid unnecessary calls to applyAffinity() during INSERT and UPDATE operations, especially for table that have indices and tables for which all columns have affinity "NONE". (check-in: 35b4d6e938 user: drh tags: insert-optimization) | |
| 01:13 | Fix the VDBE_PROFILE logic. Add a script to process the output file. (check-in: 7adb3da235 user: drh tags: trunk) | |
|
2014-02-16
| ||
| 01:55 | Enhance the code generator for INSERT INTO ... SELECT so that the SELECT generates output directly in the registers that INSERT INTO will be using, in many cases, and OP_SCopy operations can thus be avoided. (check-in: aa2d8b0e81 user: drh tags: insert-optimization) | |
|
2014-02-14
| ||
| 23:49 | Seek past NULLs in a top-constrained search. Avoid checking for NULLs in the body of the search. (check-in: e07a32f308 user: drh tags: trunk) | |
| 20:59 | Reduce the number of cases where it is necessary to check for NULL after the loop terminating condition. (check-in: 3c1ae447de user: drh tags: trunk) | |
| 15:13 | Add OP_IdxGT and OP_IdxLE as distinct opcodes. Formerly these operations where done using OP_IdxGE and OP_IdxLT with the P5 flag set. But VDBE code is easier to read with distinct opcode names. Also change OP_SeekGe to OP_SeekGE, and so forth, so that the capitalization is consistent. The whole point of this change is to improve the readability of VDBE listings. (check-in: b6bea903ac user: drh tags: trunk) | |
| 00:25 | Revise how the Tcl system encoding is handled by the test suite. (check-in: 9e573198e1 user: mistachkin tags: trunk) | |
|
2014-02-13
| ||
| 21:57 | Improvements to the makefile and README for MSVC. (check-in: b22b614068 user: mistachkin tags: trunk) | |
| 19:27 | Ensure that if the "psow=0" URI option or FCNTL_POWERSAFE_OVERWRITE file-control is used to clear the power-safe overwrite flag, extra padding frames are added to the WAL file. (check-in: 48c821fd97 user: dan tags: trunk) | |
| 19:10 | Change README to README.md and expand it. Remove unrelated and obsolete files. (check-in: 18d4e258c4 user: drh tags: trunk) | |
| 18:46 | Avoid passing a flags argument with the internal WAL_SYNC_TRANSACTIONS bit set when calling sqlite3OsSync(). (check-in: e3b79e920c user: dan tags: trunk) | |
| 13:42 | Update the tclconfig files to the latest from http://core.tcl.tk/tclconfig. (check-in: b81ba7a4bc user: drh tags: trunk) | |

| 23:52 | Minor simplifications to the "zeroPage()" routine in btree.c. (check-in: cc8f10bcb2 user: drh tags: trunk) | |
| 21:31 | Remove the "rowid cache" that sought to remember the largest rowid for a table and thereby speed up OP_NewRowid. That cache was ineffective. Removing it results in a performance increase of 0.4%, less memory usage, and a slightly smaller library size. (check-in: 56bc5ce895 user: drh tags: trunk) | |
| 14:43 | Make sure "rowid" columns are correctly resolved in joins between normal tables and WITHOUT ROWID tables. Fix for ticket [c34d0557f740c45070]. (check-in: 5d01426ddf user: drh tags: trunk) | |

| 16:24 | Increase the version number to 3.8.4 (check-in: 0a8bcbbd4e user: drh tags: trunk) | |
| 16:22 | Updates to the command-line shell. Simplify the banner message. Add the ".save" command as an alias for ".backup". When starting with no arguments, include a banner message warning that the database is transient and in-memory and mention the ".open" command. (check-in: f5ad1e1bf2 user: drh tags: trunk) | |
| 14:37 | Fixes to the "editline" support in the command-line shell. (check-in: 7989ce5f10 user: drh tags: trunk) | |
| 01:50 | Make sure that virtual WHERE-clause terms do not get transformed into real terms when processing set of OR-connected terms. Fix for ticket [4c86b126f22ad]. (check-in: c950d6c411 user: drh tags: trunk) | |

| 21:07 | Fix a pointless conditional. Add a test case. (check-in: 9367632dd7 user: drh tags: trunk) | |
| 19:59 | Add the ".save" command as an alias for ".backup". Improvements to the way font changes are implemented on the in-memory database warning. (Closed-Leaf check-in: fe284afe73 user: drh tags: memdb-warning) | |
| 19:36 | On unix, make the "transient in-memory database" text bold, but not red. Leave the text read on windows. (check-in: c9eba2f7be user: drh tags: memdb-warning) | |
| 19:27 | In the command-line shell, on the banner, warn about the use of a transient in-memory database in bold red text. (check-in: 0fbc0fcec1 user: drh tags: memdb-warning) | |
| 18:56 | Fix the compound-select-to-subquery converter so that it works with the new compound-select object linkage introduced as part of the fix for ticket [31a19d11b97088296]. (check-in: 572d4be4db user: drh tags: trunk) | |
| 16:13 | Modify the command-line shell to print a warning when using an in-memory database. (check-in: 90e9deae4a user: drh tags: memdb-warning) | |
| 15:56 | Improvements to a "Synopsis:" comment in the VDBE engine. (check-in: 0dfa7ee915 user: drh tags: trunk) | |
| 12:59 | Faster implementation for sqlite3MulInt64(). (check-in: 010c48f671 user: drh tags: trunk) | |
| 03:21 | Faster and smaller implementation of sqlite3_value_type(). (check-in: 5708bc24b8 user: drh tags: trunk) | |
|
2014-02-09

| 23:59 | Add a compound-query test to the speedtest1 test program. (check-in: 5329957591 user: drh tags: trunk) | |
| 18:02 | Use the WITH clause to help resolve names for SELECT statements on the left of a compound query. Proposed fix for ticket [31a19d11b97088296a]. (check-in: 67bfd59d90 user: drh tags: trunk) | |
