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) | |

19:20 | Use the modern MinGW major version macro, not the deprecated one. (Closed-Leaf check-in: 057c16ee97 user: mistachkin tags: mingw4x) | |
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) | |

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) | |
23:35 | Better support for MinGW 4.x. (check-in: e147230767 user: mistachkin tags: mingw4x) | |
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) | |

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) | |
15:05 | Various fixes and test case updates so that veryquick.test passes again. (Leaf check-in: f352ef57e3 user: dan tags: deferred-open) | |

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) | |
14:52 | Version 3.8.3.1 (check-in: ea3317a480 user: drh tags: release, version-3.8.3.1, branch-3.8.3) | |

03:50 | 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: de635e0960 user: drh tags: branch-3.8.3) | |
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) | |

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) | |
00:52 | Add the Mandelbrot Set testcase to the "cte" testset of speedtest1. (check-in: 56febbeb57 user: drh tags: trunk) | |

23:20 | Do away with the "multi-register pseudo-table" abstration. Instead, just use an OP_SCopy to load results directory from the result registers of the co-routine. (check-in: 1e64dd782a user: drh tags: trunk) | |
19:12 | Change the OP_Found opcode so that it expands zero-blobs prior to comparing them. Fix for ticket [fccbde530a6583b] (check-in: e2303d1b0c user: drh tags: trunk) | |
13:24 | Fix a harmless compiler warning in VS2013. (check-in: 83116ee3e0 user: drh tags: trunk) | |
