| 21:15 | Make the ieee754() a built-in function. Add the --ieee754 option to the ".dump" command in the shell to cause it to output floating-point values as ieee754() calls, so that the floating point number will be reproduced exactly. Not sure yet that we want to go this way, but it is one option. (check-in: 7fa8f16e58 user: drh tags: ieee754) | |
| 19:16 | The file_control_ofd_locks TCL command in testfixture distinguishes between OFD locks unavailable on the platform and OFD locks not used. (Leaf check-in: 87a9e9d776 user: drh tags: ofd-locks) | |
| 19:01 | OFD locks are now mostly working, but need additional tests. (check-in: 4f1fb5c94b user: drh tags: ofd-locks) | |
| 17:19 | Miscellaneous cleanup of OFD logic. Add an #if 0 to disable the use of OFD logic, temporarily, until I can get it to actually work. (check-in: d849ade396 user: drh tags: ofd-locks) | |
| 13:45 | Initial attempt to get SQLite working with OFD locks on Linux. The code here does not function correctly. This is an incremental check-in for a work in progress. (check-in: 148f8dec9a user: drh tags: ofd-locks) | |
| 11:15 | Minor change to the input grammar to make the parser tables slightly smaller. (check-in: 320fa69e6a user: drh tags: trunk) | |

| 16:08 | Fix some test case numbers in expert1.test. (check-in: b90c3c16c0 user: dan tags: trunk) | |
| 11:41 | Unless SQLITE_OMIT_AUTOINIT is defined, allow sqlite3_vfs_unregister() to be called before sqlite3_initialize(). (check-in: ab6c1ae46d user: dan tags: trunk) | |
| 11:11 | Check that malloc() has not already failed when invoking the xUpdate() method of a virtual table implementation. This fixes an assert() failure in FTS5 that could occur following an OOM condition. (check-in: e9a7e4d58f user: dan tags: trunk) | |
| 02:20 | Add the unused SQLITE_CANTOPEN_DIRTYWAL result code. This code was used in some historical versions on the apple-osx branch but was removed by check-in [27e20d699872b2b8]. Restore it so that old code that actually references that result code will still compile. (check-in: 9f40383eed user: drh tags: trunk) | |

| 18:06 | Fix the column cache invalidation logic in the code for ROWID uniqueness constraint checking in the INSERT command. This fixes ticket [c2432ef9089ee73bd]. (check-in: 0b485a571c user: drh tags: trunk) | |
| 17:35 | Add the OP_SetTabCol and OP_VerifyTabCol opcodes, only when compiling with SQLITE_DEBUG, to do run-time verification of the column cache. (check-in: b37614a367 user: drh tags: trunk) | |
| 13:10 | Strengthen the sqlite3VdbeMemAboutToChange() run-time verification mechanism to better detect missed calls to AboutToChange(). (check-in: 793e942205 user: drh tags: trunk) | |
| 01:30 | Always initialize the WhereClause.hasOr field that was added by check-in [292724ffc4]. Error detected by OSSFuzz. (check-in: 9faf41713e user: drh tags: trunk) | |

| 20:52 | Fix a typo in the amalgamation autoconf file. (check-in: de0857f396 user: drh tags: trunk) | |
| 17:43 | Add support for FILTER clause on aggregate window functions. (check-in: ceaf798ea0 user: dan tags: exp-window-functions) | |
| 16:49 | Slightly smaller and faster code by encapsulating wal-index hash table location information in a separate WalHashLoc object rather than passing around the various elements as separate variables. (check-in: 538a365b7a user: drh tags: trunk) | |
| 14:13 | Improved comments an presentation for the recent IN operator decision improvement. (check-in: 31e480f68d user: drh tags: trunk) | |
| 02:49 | Performance improvement to sqlite3WhereExprUsage(). (check-in: fd09341390 user: drh tags: trunk) | |
| 01:12 | Compute the bitmask of indexed columns for each index once when the Index objecct is constructed, instead of recomputing it every time it is needed. (check-in: d735872ec3 user: drh tags: trunk) | |
| 00:09 | Avoid invoking the whereLoopAddOr() routine in the query planner if there are no OR operators in the WHERE clause, thus speeding up query planning slightly. (check-in: 292724ffc4 user: drh tags: trunk) | |
|
2018-06-08
| ||
| 23:23 | When the query planner has the opportunity to use an IN operater constraint on a term of an index other than the left-most term, use the estimated number of elements on the right-hand side of the IN operator to determine if makes sense to use the IN operator with index lookups, or to just do a scan over the range of the table identified by the index terms to the left. Only do this if sqlite_stat1 measurements are available as otherwise the performance estimates will not be accurate enough to discern the best plan. Bias the decision slightly in favor of using index lookups on each element of the IN operator. (check-in: 2cbbabdf5e user: drh tags: trunk) | |
| 21:21 | Only choose to scan an IN operator rather than use an index if we have real STAT1 data to suggest it is advantageous. (Closed-Leaf check-in: 30e874661d user: drh tags: in-scan-vs-index) | |
| 20:58 | Add support for the WINDOW clause. (check-in: 19c983b511 user: dan tags: exp-window-functions) | |
| 19:54 | Merge the btreeNext() assertion bug fix from trunk. (check-in: 11bd66e090 user: drh tags: in-scan-vs-index) | |
| 19:13 | Fix an assert() that can be false for a corrupt database and a strange query that uses a recursive SQL function to delete content from a corrupt database file while it is being queried. (check-in: 99057383ac user: drh tags: trunk) | |
| 18:22 | Consider doing a partial table scan to fulfill an IN operator rather than using an index. Try to pick the plan with the lowest cost. (check-in: 1fa40a78fe user: drh tags: in-scan-vs-index) | |
| 16:11 | Do not flatten sub-queries that contain window functions. (check-in: 236cb75bd1 user: dan tags: exp-window-functions) | |
| 11:45 | Fixes to allow group_concat() to be used as a window function. (check-in: 89bbc9ba8f user: dan tags: exp-window-functions) | |

| 20:35 | Merge latest trunk changes with this branch. (check-in: 2510220342 user: dan tags: exp-window-functions) | |
| 20:08 | Add window functions lag() and lead(). (check-in: ef34207073 user: dan tags: exp-window-functions) | |
| 18:13 | The IN-early-out optimization: When doing a look-up on a multi-column index and an IN operator is used on a column other than the left-most column, then if no rows match against the first IN value, check to make sure there exist rows that match the columns to the right before continuing with the next IN value. (check-in: 09fffbdf9f user: drh tags: trunk) | |
| 18:01 | Fix the assert()s in the byte-code engine that prove that cursors are unidirectional. (Closed-Leaf check-in: 4b0b4e1403 user: drh tags: multikey-opt-idea) | |
| 17:45 | Add support for window function first_value(). (check-in: 060b264028 user: dan tags: exp-window-functions) | |
| 17:32 | Remove the NextIfOpen and PrevIfOpen opcodes which are no longer needed when the IN-early-out optimization is working. (check-in: 439c816227 user: drh tags: multikey-opt-idea) | |
| 16:07 | Test cases. (check-in: 085e863713 user: drh tags: multikey-opt-idea) | |
| 15:54 | Fix problems with the nth_value() function. (check-in: 63002b9a09 user: dan tags: exp-window-functions) | |
| 15:28 | Merge the ".stat/.eqp" CLI fix from trunk. (check-in: a91cad3381 user: drh tags: multikey-opt-idea) | |
| 15:23 | Avoid using a prepared statement for ".stats on" after it has been closed by the ".eqp full" logic. Fix for ticket [7be932dfa60a8a6b3b26bcf76]. (check-in: bb87c054b1 user: drh tags: trunk) | |
| 14:59 | Add the WHERE_IN_EARLYOUT flag and use it to clarify the logic of this optimization. (check-in: 522f1eacc2 user: drh tags: multikey-opt-idea) | |

| 23:31 | Change a comma into a logically equivalent but semantically clearer semicolon. (check-in: 71f97f0f82 user: drh tags: trunk) | |
| 20:55 | More space and performance enhancements to sqlite3VdbeRecordCompare(). (check-in: 83a60ff056 user: drh tags: trunk) | |
| 20:51 | Add implementation of nth_value() window function. (check-in: eb1fb420ac user: dan tags: exp-window-functions) | |
| 20:29 | Small performance optimization in sqlite3VdbeRecordCompareWithSkip() for the common case where the comparison is equal. (check-in: 1e616e256a user: drh tags: trunk) | |
| 19:48 | Rearrange the order of some checks in the integrity_check pragma for a very slight performance gain. (check-in: 4b853f0205 user: drh tags: trunk) | |
| 18:50 | Fix the sqlite3BeginTrans() calls within the snapshot extension. (check-in: 1fef7ad25b user: drh tags: trunk) | |
| 17:45 | Another minor optimization to OP_Transaction. (check-in: d80077aee3 user: drh tags: trunk) | |

| 17:03 | Merge changes from trunk, including all the 3.24.0 changes plus some later enhancements. (check-in: d7299bfeb1 user: drh tags: begin-concurrent) | |
| 16:28 | Change sqlite3BtreeBeginTrans() to return the BTREE_SCHEMA_COOKIE, for a small speed improvement when starting new transactions. (check-in: a10662aa91 user: drh tags: trunk) | |
| 01:18 | Fix the ".archive" command in the CLI (and the corresponding -A command-line option) so that it silently ignores filenames that contain "../" in their names. This prevents the "Zip Slip" attack. (check-in: 27291f2d7f user: drh tags: trunk) | |
| 00:36 | Attempt to optimize the resolveExprStep() routine by mapping Expr opcodes into a subset of opcodes that resolveExprStep() cares about and only calling the routine when those opcodes are encountered. Is slightly faster, but it seems like the very slight performance bump is not worth the added complexity. Saved on a dead-end branch for historical reference. (Closed-Leaf check-in: bad4d7a0d9 user: drh tags: dead-end) | |

| 23:51 | Update the version number to 3.25.0 for the next development cycle. (check-in: 7598236c35 user: drh tags: trunk) | |
| 23:21 | Avoid unnecessary loads of columns in an aggregate query that are not within an aggregate function and that are not part of the GROUP BY clause. (check-in: e15e100660 user: drh tags: trunk) | |
| 20:45 | Add the OP_IfNoHope and OP_SeekHit opcodes used to reduce the number of unnecessary sqlite3BtreeMovetoUnpacked() calls when checking for an early exit on IN-operator loops. Futher optimizations are likely possible here. (check-in: 6bf251af43 user: drh tags: multikey-opt-idea) | |
| 20:04 | Calculate non-aggregate expressions in the SELECT list of an aggregate query that does not use min() or max() once per group, instead of once per row visited. (Closed-Leaf check-in: dce2dfbe15 user: dan tags: exp-agg-opt) | |
| 16:16 | Add implementation of last_value() window function. (check-in: 2493ce1a40 user: dan tags: exp-window-functions) | |
| 15:16 | Use an OP_NotFound opcode to cancel futile IN operators early. The current implementation is suboptimal because it always runs teh OP_NotFound. This still needs to be enhanced to only do the OP_NotFound if no results have been seen on the current loop. (check-in: 87a9fc504f user: drh tags: multikey-opt-idea) | |
| 13:54 | Merge trunk changes. (check-in: 047295c588 user: drh tags: multikey-opt-idea) | |
| 13:43 | Update and correct the documentation on the OP_OpenRead, OP_OpenWrite, and OP_ReopenIdx opcodes. No code changes other than the addition of an assert(). (check-in: 8a0b730d0e user: drh tags: trunk) | |

| 12:05 | Fix the CSV extension so that it works with single-column CSV files. (check-in: e336cf0048 user: drh tags: trunk) | |
| 11:31 | Ensure that sqlite3AuthRead() is only call for TK_COLUMN and TK_TRIGGER expression nodes. This fixes a harmless assert() identified by OSSFuzz. Move the assert() into a position where it is tested even if the authorizer is disabled. (check-in: d0c3beef7c user: drh tags: trunk) | |

| 00:54 | Demonstration code on a possible technique for optimizing the use of IN operator on columns to the right of multicolumn indexes. If the OP_Noop generated where were really a new opcode that checked to see if there existed any entries in the index with a matching prefix, it might prevent unnecessary iterations of the IN operator.

| 16:00 | Store application-defined function names as lower-case to avoid the need for case conversions before calling xFindFunction on virtual tables. Avoid using lookaside to store the destructors for application defined functions, as lookaside should be reserved for transient allocations. (check-in: 777189ce88 user: drh tags: trunk) | |
