| 13:54 | Use the VList object to capture the mapping between SQL parameter names and variable numbers in a single memory allocation. (check-in: 99fddf2ecb user: drh tags: trunk) | |
| 13:52 | Add check to prevent a VList from growing after pointers to labels have been taken. (Closed-Leaf check-in: aa23d7eaf6 user: drh tags: VList) | |
| 13:30 | Fix the VList object so that it actually works. (check-in: 9dcd85698a user: drh tags: VList) | |
| 03:59 | Use the VList object to replace Parse.azVar for tracking the mapping between SQL parameter names and parameter numbers. There is a performance improvement, though there are still a few hiccups in the current code. (check-in: 68ecafa142 user: drh tags: VList) | |

| 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) | |

| 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) | |

| 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) | |

| 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) | |

| 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) | |

| 21:11 | 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) | |
|
2016-12-14

| 13:54 | Increase the size of the reference count on Table objects to 32 bits. (check-in: d08b72c38f user: drh tags: trunk) | |
| 11:39 | Fix the configure makefile to align it with the manual makefile. Unsaved changes from the previous check-in. (check-in: 00a184b65f user: drh tags: trunk) | |
| 11:23 | Adjust the unix makefiles so that "make test" runs fuzzcheck prior to even attempting to build the other test programs. (check-in: bb48f7a559 user: drh tags: trunk) | |
| 11:14 | Three times faster sqlite3SrcListAppend() in the common case by avoiding the call to sqlite3SrcListEnlarge() for the first allocation. (check-in: 0ea2762f1d user: drh tags: trunk) | |

| 23:22 | In the command-line shell, in the output of the ".dump", ".schema", and ".fullschema" commands, convert CREATE TABLE statements that appear to come from shadow tables into CREATE TABLE IF NOT EXISTS statements. (check-in: c7021960f5 user: drh tags: trunk) | |
| 20:30 | Fix harmless compiler warnings. (check-in: ed2c9f3738 user: drh tags: trunk) | |

| 18:34 | In the pager, avoid checking for the illegal page number 0 except when creating a new page. (Closed-Leaf check-in: dee20ba982 user: drh tags: pager-get-method) | |
| 16:57 | Fix a problem causing SQLite to return false "foreign key violation" errors when there is a partial (i.e. WHERE constrained) UNIQUE index on the parent key columns. This bug did not cause SQLite to allow illegal data to be inserted into the database, only to reject legal operations. (check-in: 850877d1ea user: dan tags: trunk) | |
| 15:53 | Further refinements to the virtual method implementation of sqlite3PagerGet(). (check-in: 67df444648 user: drh tags: pager-get-method) | |

|
2016-12-12
| ||
| 23:24 | Add the --mmap option to the speedtest1 program and to the speed-check.sh script that is frequently used to run speedtest1. (check-in: 1a636d5e0e user: drh tags: trunk) | |
| 18:12 | Remove unnecessary MemPage initialization resets in the autovacuum ptrmap processing. (check-in: 1b36fbb9f0 user: drh tags: trunk) | |
