| 14:53 | Add the vfsstat.c loadable extension - a VFS shim that measures the amount of I/O, and an eponymous virtual table that is used to extract and view the measurements. (check-in: 0987487dd4 user: drh tags: trunk) | |
| 00:13 | Clang can define _MSC_VER in some circumstances; therefore, check for Clang first. (Closed-Leaf check-in: 3f710bc361 user: mistachkin tags: ctimeCompiler) | |

| 21:13 | Check for Clang before GCC. (check-in: 7c2cd4b05f user: mistachkin tags: ctimeCompiler) | |
| 20:30 | Remove surplus quotation marks from the COMPILER= compile_options setting for Clang. (check-in: 5c966f2000 user: mistachkin tags: ctimeCompiler) | |
| 19:34 | Remove surplus quotation marks from the COMPILER= compile_options setting for GCC. (check-in: 664c132dab user: drh tags: ctimeCompiler) | |
| 18:09 | Add basic compiler information to the results of 'PRAGMA compile_options'. (check-in: d734e2df40 user: mistachkin tags: ctimeCompiler) | |
| 12:30 | Improvements to WHERE-clause debug tracing. Show TK_MATCH expressions and show more details on WhereTerm traces. (check-in: 71087c12bc user: drh tags: trunk) | |
| 04:10 | Fix Lemon so that it actually works with -DYYSTACKDEPTH=0. (check-in: a9be4c2d56 user: drh tags: trunk) | |
| 01:07 | Fix the Lemon-generated parser so that it compiles with -DYYSTACKDEPTH=0. It does compile now, but there are subtle issues still. (check-in: 28d439f816 user: drh tags: trunk) | |
|
2016-05-26
| ||
| 20:56 | Add a new OP_SeekRowid opcode, that combines the functions of OP_MustBeInt and OP_NotExists. This makes the code slightly smaller and faster. (check-in: ffe80a1bfa user: drh tags: trunk) | |
| 20:52 | Add further instrumentation to the bc_test1.c test app. (check-in: 5528de4a53 user: dan tags: begin-concurrent) | |
|
2016-05-25
| ||
| 18:53 | Add the libvers.c tool in the tool/ subdirectory. (check-in: 2a41f098b2 user: drh tags: trunk) | |
|
2016-05-24
| ||
| 18:55 | Enhance Lemon and the parser template so that it can once again build parsers that have no unreachable branches. (check-in: 41fd46e296 user: drh tags: trunk) | |
| 18:50 | Minor change to the walcrash4.test module so that it works when SQLITE_DEFAULT_WAL_SYNCHRONOUS is set to something other than 2. (check-in: 61e239bc43 user: drh tags: trunk) | |
| 16:20 | Fix an obscure problem with transactions written in "PRAGMA synchronous=full" mode on systems that do not support POWERSAFE_OVERWRITE causing an xSync() call to be omitted if the last frame written by a transaction is aligned to a sector boundary. This means that if a power failure or OS crash occurs very soon after such a transaction is committed, it may be lost following system recovery. (check-in: 37de3eab67 user: dan tags: trunk) | |
| 00:40 | Improvements to the initialization of the push-down automoton for the Lemon-generated parser. Smaller and faster. (check-in: 3b28b68e23 user: drh tags: trunk) | |
|

| 21:56 | Use a pointer to the top of the stack rather than an index into the stack in the Lemon-generated parser template, for about 6.6% parser performance gain. (check-in: 3c2a770549 user: drh tags: trunk) | |
| 19:02 | Avoid a minor error message when running RTREE without an sqlite_stat1 table. (check-in: 276e92f5b4 user: drh tags: trunk) | |
| 18:27 | Fix the rtreeG.test test case. (Closed-Leaf check-in: 9589e93771 user: drh tags: tree-stat1-fix) | |
| 18:12 | Fix RTREE so that it does not run queries against the sqlite_stat1 if that table does not exist. (check-in: 48526a2fe5 user: drh tags: tree-stat1-fix) | |
| 18:06 | Remove an extra "finish_test" from the end of rtreeC.test. (check-in: bfbb6dd84b user: drh tags: tree-stat1-fix) | |
| 16:16 | Improve the error messages generated by the rtree module when a constraint fails. (check-in: 3ad2531efb user: dan tags: trunk) | |
| 16:15 | Lemon enhancement: avoid unnecessary reduce actions that convert one non-terminal into another but have no side effects. (check-in: a86e782ad1 user: drh tags: trunk) | |
| 14:24 | Fix comment typos and improve clarity of presention in Lemon. The output should be identical. (check-in: b91a5b8297 user: drh tags: trunk) | |
| 02:57 | Merge changes from trunk. (check-in: 815cc2bb48 user: drh tags: apple-osx) | |
| 00:10 | Update the configure script with additional hints on the location of tclConfig.sh, hints needed by the latest versions of Xcode. (check-in: 90411a2816 user: drh tags: trunk) | |
|

| 23:25 | More tweaks to improve the performance of the insert logic, slightly. (check-in: dec1307581 user: drh tags: trunk) | |
| 20:03 | Simplify the sqlite3BtreeInsert() interface by gathering the five arguments describing the content to be inserted into the new BtreePayload structure, and thus reducing the number of parameters from eight to four. (check-in: 55f348cdd2 user: drh tags: trunk) | |
| 19:10 | Remove some unused legacy code from the btree insert logic. (check-in: 2ce1166717 user: drh tags: trunk) | |
| 18:50 | Use pthreads mutexes and conditions to synchronize threads in bc_test1. (check-in: f33aa76f07 user: dan tags: begin-concurrent) | |
| 12:29 | Yet another minor size reduction and performance increase in the b-tree insert logic. (check-in: 1dbaf7a119 user: drh tags: trunk) | |
| 11:23 | Small size reduction and performance increase in the sqlite3BtreeInsert() logic. (check-in: 656aa1ecf5 user: drh tags: trunk) | |
| 00:45 | Add the shell-script used for routine performance testing. (check-in: 8e366f18f5 user: drh tags: trunk) | |
|

| 23:51 | Add a simple TCL script for summing cachegrind information for each VDBE opcode. (check-in: 96cf821b6a user: drh tags: trunk) | |
| 21:40 | Another optimization on the OP_Column opcode. (check-in: 1765672c25 user: drh tags: trunk) | |
| 20:58 | Fix typo in comment. (check-in: 9db8f21473 user: mistachkin tags: trunk) | |
| 19:51 | Slight performance improvement in the OP_Column opcode. (check-in: 5c15747439 user: drh tags: trunk) | |
| 18:09 | Remove the sqlite3PagerClearCache() routine, which does not accomplish anything useful. (check-in: f250166bb3 user: drh tags: trunk) | |
| 15:53 | Performance optimization and size reduction on the freeP4() routine. (check-in: 4dc56e8684 user: drh tags: trunk) | |
| 15:24 | Increase the version number to 3.14.0 since we are already making significant code changes. (check-in: 1a0d05765f user: drh tags: trunk) | |
| 15:15 | Use sqlite3VdbeAddOp0() to code OP_Expire, to save a few bytes. (check-in: 3d55d24dcb user: drh tags: trunk) | |
| 14:54 | Optimizations to link list merge sort code in vdbesort.c, pcache.c, and rowset.c. Resulting binaries are 10 bytes smaller and use 0.03% fewer CPU cycles. (check-in: 9033afbb31 user: drh tags: trunk) | |
| 14:11 | For queries with both ORDER BY and LIMIT, if the rows of the inner loop are emitted in ORDER BY order and the LIMIT has been reached, then optimize by exiting the inner loop and continuing with the next cycle of the first outer loop. (check-in: 559733b09e user: drh tags: trunk) | |
| 13:44 | Set the NULLEQ flag on the sequence counter comparison in the ORDER BY LIMIT optimization, to avoid coverage complaints about not testing the NULL case. (Closed-Leaf check-in: ed1b30dc93 user: drh tags: orderby-limit) | |
| 12:22 | Autoconf configure.ac adjustment to try to get it to look for both editline and readline automatically. (check-in: 645bd696df user: drh tags: trunk) | |
| 00:21 | A few simple test cases for the ORDER BY LIMIT optimization. (check-in: 08849eab0f user: drh tags: orderby-limit) | |
|

| 22:40 | Appears to work now. Needs test cases, more comments, and code optimization. (check-in: 990fe50c91 user: drh tags: orderby-limit) | |
| 22:13 | In a query with both ORDER BY and LIMIT, if the inner loop satisfies the ORDER BY then try to cut short each invocation of the inner loop once the LIMIT has been satisfied. This check-in is a partial implementation only. (check-in: 852d1eda6e user: drh tags: orderby-limit) | |
| 19:31 | Fixup comments on wctrlFlags value definitions. (check-in: 58b516e8c0 user: drh tags: trunk) | |
| 18:56 | Clean up the WHERE_* macros used for the wctrlFlags parameter on the sqlite3WhereBegin() interface, freeing up some bits to be used for other things. (check-in: d01305841d user: drh tags: trunk) | |
