| 14:53 | Fix harmless compiler warnings. (check-in: fa86db2f91 user: drh tags: trunk) | |
|
2016-12-21
| ||
| 21:26 | Change the default lookaside configuration from 500 slots of 128 bytes each to 125 slots of 512 bytes each. This uses the same amount of memory (64,000 bytes) but seems to perform much better in test applications. (check-in: 52a12e47de user: drh tags: trunk) | |
| 19:45 | Simplifications to the way UnpackedRecord objects are allocated. Smaller and faster code that also fixes a subtle (currently unreachable) bug. (check-in: f7ab01f254 user: drh tags: trunk) | |
|
2016-12-18
| ||
| 17:42 | Change the OP_IfNotZero opcode so that it decrements register P1 by 1 rather than the value in P3, and so that it only decrements if originally positive. This avoids decrementing the smallest 64-bit signed integer. (check-in: 165c044686 user: drh tags: trunk) | |
|
2016-12-17
| ||
| 21:07 | Refinements to the new dbfuzz test program. (check-in: 50325abe79 user: drh tags: trunk) | |
| 20:27 | Enhance fuzzershell.c to read and execute SQL commands in the autoexec table of the database under test. Add the dbfuzz.c test program combining selected features of fuzzershell.c and fuzzcheck.c. (check-in: ef6e071a62 user: drh tags: trunk) | |
| 08:18 | Fix a problem in the shell tools readfile() command causing blobs to be truncated at the first embedded 0x00 byte in release builds, or an assert() to fail in a debug build. (check-in: 8dedd6ad44 user: dan tags: trunk) | |
|
2016-12-16
| ||
| 21:29 | Merge recent enhancements from trunk, and especially the pragma-as-vtab change. (check-in: 4b1e780433 user: drh tags: apple-osx) | |
| 21:15 | Merge the pragma-as-vtab enhancement from trunk. (check-in: 89250777b2 user: drh tags: est_count_pragma) | |
| 21:02 | Fix a potential memory leak following an OOM error in the pragma processing. (check-in: 396ab8f87e user: drh tags: est_count_pragma) | |
| 18:43 | Add the ".lint fkey-indexes" command to the command-line shell. (check-in: 94689e3bda user: drh tags: trunk) | |
| 18:41 | Fix minor issues with the ".lint" command implemention in the shell and the shell help text related to ".lint". (Closed-Leaf check-in: 1268dc7771 user: drh tags: fkey-missing-indexes) | |
| 18:14 | Built-in PRAGMA statements without side-effects can be invoked as table-valued functions by prefixing their name with "pragma_". (check-in: d66ec5cfb6 user: drh tags: trunk) | |
| 17:28 | Change ".fkey_missing_indexes" to ".lint fkey-indexes". (check-in: ee621ade38 user: dan tags: fkey-missing-indexes) | |
| 16:49 | Experimental merge of the est_count_pragma and the pragma-as-vtab branches. (Closed-Leaf check-in: 4b73ee33f3 user: drh tags: est-count-pragma-vtab) | |
| 16:44 | Update .fkey_missing_indexes to use the built-in pragma vtabs. (check-in: 3ab05987b0 user: dan tags: fkey-missing-indexes) | |
| 16:13 | Merge the pragma-as-vtab change into this branch. (check-in: 4ba45e7223 user: dan tags: fkey-missing-indexes) | |
| 15:57 | Merge recent trunk enhancements. (check-in: 74a0ca1f15 user: drh tags: est_count_pragma) | |
| 15:05 | Fix a problem causing the planner to generate sub-optimal plans for some queries that use recursive WITH sub-queries with LIMIT clauses. (check-in: 053a149cc8 user: dan tags: trunk) | |
| 04:20 | Fix an error in the way the "schema" argument to some pragma virtual tables is handled. (Closed-Leaf check-in: 546821e29e user: drh tags: pragma-as-vtab) | |
| 02:31 | Simplifications to facilitate full test coverage. (check-in: 01afc51597 user: drh tags: pragma-as-vtab) | |
| 02:14 | Minor bug fixes and enhancements to the pragma eponymous virtual tables. (check-in: 3f8f461504 user: drh tags: pragma-as-vtab) | |
| 01:09 | Merge enhancements from trunk, and especially the ability to use temp.sqlite_master as an alias for sqlite_temp_master. (check-in: 994a4401f5 user: drh tags: pragma-as-vtab) | |
| 01:00 | All temp.sqlite_master to be used as an alias for sqlite_temp_master. (check-in: 8d646905b8 user: drh tags: trunk) | |

| 21:33 | Fix the cost estimation in the BestIndex method of the eponymous pragma virtual table implementation. (check-in: 7126807a18 user: drh tags: pragma-as-vtab) | |
| 21:11 | The pragma as eponymous virtual table mechanism now appears to work. (check-in: 2c274a1a7b user: drh tags: pragma-as-vtab) | |
| 20:59 | Code to automatically create eponymous virtual tables for read-only pragmas. Compiles, but does not yet work. (check-in: 988a61e8b0 user: drh tags: pragma-as-vtab) | |
| 18:59 | Do exponential rather than linear expansion of the SrcList.a array when appending new elements, to reduce the number of malloc() calls. (check-in: 4e3749127e user: drh tags: trunk) | |
| 16:01 | Do more pragma processing from tables rather than in-line code. (Closed-Leaf check-in: a88ca3524b user: drh tags: table-driven-pragma) | |
| 06:01 | Add the -groupbyparent option to the ".fkey_missing_indexes" command. (check-in: 976c51b483 user: dan tags: fkey-missing-indexes) | |
|

| ||
| 19:28 | Add the experimental ".fkey_missing_indexes" command to the shell tool. To identify indexes that should be created on child keys if FK processing is to be enabled. (check-in: 7df23aca1f user: dan tags: fkey-missing-indexes) | |
| 14:07 | Refactor the Table.nRef field as Table.nTabRef for easier grepping. (check-in: 9cae4c2e30 user: drh tags: trunk) | |
