20:40
Automatically generated comments on many VDBE opcodes when in SQLITE_DEBUG mode. Comments derive from the "Synopsis:" field added to each opcode definition in vdbe.c. (check-in: 5f310c6a user: drh tags: trunk)
16:14
Improved comments on the constraint checking logic. (check-in: 141a38a7 user: drh tags: omit-rowid)

2013-10-26
15:40
Work on the UPDATE and INSERT logic. This is an incremental check-in so that can switch over to trunk to work on an unrelated issue there. (check-in: 086ec2a1 user: drh tags: omit-rowid)
13:36
Replace the OP_IsUnique opcode with OP_NoConflict. This code simplification might be useful to move onto trunk even if this branch is never merged. (check-in: e6650e16 user: drh tags: omit-rowid)
00:58
Minor refactoring of variable names and fixes to comments in insert.c. (check-in: ae61a343 user: drh tags: omit-rowid)
2013-10-25
19:17
Progress toward getting UPDATE to work in WITHOUT ROWID tables. (check-in: e557b7d8 user: drh tags: omit-rowid)

2013-10-24
19:48
Update the interface to the sqlite3GenerateRowDelete() utility so that it is able to handle WITHOUT ROWID tables. The implementation still needs to be completed. (check-in: 85daf517 user: drh tags: omit-rowid)
15:20
Add the ".open" command to the command-line shell. (check-in: 21eccb91 user: drh tags: trunk)

11:55
Remove an obsolete comment from the VDBE. No code changes. (check-in: 53bb070c user: drh tags: omit-rowid)
00:18
Correctly handle queries that use secondary indices of WITHOUT ROWID tables. (check-in: d8bc8595 user: drh tags: omit-rowid)
2013-10-23
23:37
Change the sqlite3OpenTable() utility to open the PRIMARY KEY index when reading a WITHOUT ROWID table. (check-in: 247f3899 user: drh tags: omit-rowid)

2013-10-22
18:01
The Index object now has nKeyCol and nColumn. nColumn is the total number of columns and nKeyCol is the number of key columns. Currently these always differ by one. Refactor aiColumn[] to be of type i16 instead of int. (check-in: a106ce86 user: drh tags: omit-rowid)
14:28
Add a procedure to handle the messy details of allocating an Index object from the heap. (check-in: 45efc94f user: drh tags: omit-rowid)
10:23
Extra backwards-compatibility tests verify that UNIQUE and PRIMARY KEY indices are created in the correct order. Other backwards-compatibility tests already cover this, but it does not hurt to double up. (check-in: 5ca0ea2e user: drh tags: omit-rowid)
01:18
Previous refactor is not going to be helpful because implied indices must be created in the same order that they appear in the CREATE TABLE statement for backwards compatibility. This is a much smaller change to clean up a few loose ends. (check-in: 824b549f user: drh tags: omit-rowid)
2013-10-21

2013-10-19
23:31
Experimental changes toward "index only" tables. Add the ability to specify options on CREATE TABLE statements using the WITH clause modeled after PostgreSQL and SQL Server. Only the "omit_rowid" option is currently recognized and that option is currently a no-op. (check-in: 0248ec5e user: drh tags: omit-rowid)
16:51
Improved header comment with better instructions on the vfslog.c extension. (check-in: 4bd592c8 user: drh tags: trunk)

20:03
Add the SQLITE_FCNTL_TRACE file control and generate it for OP_Trace when compiled with SQLITE_USE_FCNTL_TRACE. Update vfslog.c to make use of the new file control. Also update vfslog.c to log UNLOCK events before the fact, rather than afterwards. (check-in: e801f35a user: drh tags: trunk)
17:42
Further enhance the vfslog extension to record the number of freelist pages and the first freelist page in CHNGCTR-READ and CHNGCTR-WRITE records. (check-in: 08157524 user: drh tags: trunk)

17:32
Multiply all cursor step cost estimates by the estimated size of the row in bytes, in order to get the query planner ot make use of estimated row sizes. This check-in uses magic numbers in a few places (for example, estimates of the size of output rows) and needs lots of refinement. Consider this a proof-of-concept only.

If an "INSERT INTO ... SELECT" can use the xfer optimization, pass the OPFLAG_BULKCSR hint to btree cursors used to update indices. This results in a tighter key packing. (check-in: 087af29e user: dan tags: trunk)
00:00
Make sure the count(*) optimization works correctly even when partial indices are present. Ticket [a5c8ed66cae]. (check-in: 9f2f4c0a user: drh tags: trunk)

Merge latest trunk changes. (Closed-Leaf check-in: 24aa20da user: dan tags: fts4-docid-range-constraints)
19:27
Allow FTS4 multi-token phrases to use a combination of in-memory and incrementally loaded doclists. This allows phrases to (partially) benefit from incremental doclists without disabling the deferred token optimization. (check-in: f6819c5f user: dan tags: fts4-docid-range-constraints)
15:39
The sqlite3FixInit() routine cannot fail. So change the return type from "int" to "void". (check-in: 500c5932 user: drh tags: trunk)
14:08
Rework the PRAGMA implementation to only call sqlite3ReadSchema() from a single place, based on a flag in the pragma table, rather than separately from each case which needs the schema. (check-in: 8338232a user: drh tags: trunk)

12:40
Updates to the sqlite3_analyzer utility: Change the names of some labels, especially change "Fragmentation" to "Non-sequential pages". Revise the computation of non-sequential pages so that it ignores itercalated non-leaf pages (overflow and index pages). (check-in: 3e5c7771 user: drh tags: trunk)
2013-09-26
15:21

2013-09-09
19:37
Make sure that the transitive constraint optimization does not cause WHERE clause terms to be disabled prematurely. We are unable to find a test case that fails because of this, but it seems prudent to make this preventative change nevertheless. (check-in: d6e361d7 user: drh tags: trunk)
2013-09-07
00:29
Continuing refinements of the logic to take WHERE clause terms not used for indexing into account when computing the number of output rows from each table. (check-in: b65dc534 user: drh tags: unlikely-func)
2013-09-06

Fix a problem causing SQLite not to use stat4 or stat3 data to analyze constraints of the form "column = expr COLLATE collation" (those with an explicit COLLATE on the non-column side of the comparison operator). (check-in: 1e86d81d user: dan tags: trunk)
17:01
Enhancements to the Win32 API definition macros. (check-in: b1811baa user: mistachkin tags: cygwinTempPath)

Improvements to the robust_open() logic in the unix VFS so that if an attempt is made to open a repository on file descriptors 0, 1, or 2, and blocking that file descriptor by opening it on /dev/null fails, then the open will fail. (check-in: d9c018f8 user: drh tags: trunk)
2013-08-29
23:36
Make the unix VFS defensive against the error of having a database file open on file descriptors 1 or 2, as an error message might easily be written onto those file descriptors and thus overwrite and corrupt the database. (check-in: 30d38cc4 user: drh tags: trunk)
