| 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) | |
| 14:43 | Make sure "rowid" columns are correctly resolved in joins between normal tables and WITHOUT ROWID tables. Fix for ticket [c34d0557f740c45070]. (check-in: 5d01426ddf user: drh tags: trunk) | |
| 14:43 | Merge latest trunk changes. (check-in: 4d7057c494 user: dan tags: deferred-open) | |

| 19:35 | Test case updates to account for the fact that database files are not created until they are first written. (check-in: 8ef97420b2 user: dan tags: deferred-open) | |
| 16:31 | Sync with trunk. Bring in the command-line shell updates and the new 3.8.4 version number. (check-in: 2cd35ff651 user: drh tags: sessions) | |
| 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) | |
| 14:37 | Fixes to the "editline" support in the command-line shell. (check-in: 7989ce5f10 user: drh tags: trunk) | |
| 05:26 | Merge latest trunk changes. (check-in: 1f2e1b0c64 user: dan tags: deferred-open) | |
| 04:30 | Sync the latest trunk changes, and in particular the STAT4 IS NOT NULL fix. (check-in: b006792695 user: drh tags: sessions) | |
| 03:55 | Increase the version number to 3.8.3.1. (check-in: 3111df71b2 user: drh tags: 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) | |

| 21:09 | Fix a bug causing the POWERSAFE_OVERWRITE device-characteristic flag to be set incorrectly if file opening is deferred. (check-in: 95d0c58d27 user: dan tags: deferred-open) | |
| 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) | |
| 19:37 | Experimental change to os_unix.c to delay creating a database file until it is first written. (check-in: 538f7b25e4 user: dan tags: deferred-open) | |
| 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) | |

| 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) | |
| 13:22 | Fix a harmless compiler warning in VS2013. (check-in: 35f2793db5 user: drh tags: branch-3.8.3) | |
