20:00 On unix, the "PRAGMA fsync_interval=N" command causes an extra fdatasync() after writing N bytes of content, to force a write-queue flush in the underlying OS. This is an experimental hack that is not expected to land on trunk. Leaf check-in: b18cc5fee4 user: drh tags: write-queue-flush-hack
16:46 Enable the ".wheretrace" and ".selecttrace" options in the shell when configure is run using --enable-debug. This mirrors a similar change that has already occurred on trunk. Leaf check-in: c4f798b212 user: drh tags: branch-3.9.2
01:56 Enhance the PRAGMA noop_update statement so that the behavior persists across reprepare operations. Leaf check-in: c25da6de1d user: drh tags: noop-update-reprepare
00:30 Enable the one-pass optimization for DELETE and UPDATE on RTree. This is parked in a branch because is seems to make no measureable performance difference. Leaf check-in: 8b8314cb9b user: drh tags: rtree-one-pass
16:59 Experiments with the regexp.c extension, trying to get it to report the exact substring that matches the RE. Leaf check-in: 3d6fba623a user: drh tags: regexp-span

07:56 Add new interfaces sqlite3_result_pointer(), and sqlite3_value_pointer() and use them to transfer the eponymous FTS3 column pointer to the snippet() and offsets() routines. This changes is a cherry-pick of [f0f49224] via [69906880cee] and is ultimately inspired by check-in [72de49f2]. Leaf check-in: 8201f4e1c5 user: drh tags: branch-3.18
04:08 Add new interfaces sqlite3_result_pointer(), and sqlite3_value_pointer() and use them to transfer the eponymous FTS3 column pointer to the snippet() and offsets() routines.

19:06 Avoid adding an artifical "LIMIT 1" on scalar subqueries that do not need it. This seems like a pointless optimization as it makes minimal run-time difference but does increase code complexity. Parked on a branch for historical reference. Leaf check-in: c21628e9c1 user: drh tags: subquery-limit-opt
10:15 Failed version 3.18.1. Somehow I managed to omit the bug fix which was the entire purpose of 3.18.1 in the first place! Leaf check-in: e3038fbfc2 user: drh tags: mistake
10:55 Cause the ANALYZE command to build sqlite_stat1 table entries for empty tables with the assumption that such tables really contain 10 elements. This gives better query plans for tables that are truely empty, but is likely to cause problems in legacy systems, so the change is kept off trunk. Some TCL tests fail on this check-in due to the new stat1 entries. Leaf check-in: c81f260c2d user: drh tags: analyze-empty-tables
18:05 Add debugging functions btreePageOriginFile() and btreePageOriginOffset(). Leaf check-in: 214d238a47 user: dan tags: btree-debug

14:47 Before beginning an incremental checkpoint in RBU, sync the directory containing the target database file. This ensures that the new directory entry created by renaming the *-oal file to *-wal is synced to disk. Cherrypick of [915a9a28]. Leaf check-in: 694fe0b22b user: dan tags: version-3.17.0-rbu-fixes
14:04 The VDBE cycle counts for the sqlite3_progress_handler() callback are now cumulative. Leftovers from the previous statement are applied to the next statement. Leaf check-in: 7a62fc6abc user: drh tags: cumulative-progress-count

20:05 Add an optimization to OP_Column to speed up sequential OP_Column instructions that read earlier fields from the same cursor. Attempt to reorder OP_Column opcodes so as to take advantage of this. Leaf check-in: c1adf95958 user: dan tags: sort-column-opcodes
21:23 Increase the estimated cost of sorting when sorting wide results sets, to account for the extra storage space and I/O required for the external sort. Leaf check-in: 38298ef923 user: drh tags: apple-increased-sorting-cost

21:35 Attempt to treat the arguments to a table-valued function as if they occur in the ON clause of a LEFT JOIN rather than in the WHERE clause. But this causes undesirable behavior with generate_series, as demonstrated by test cases. This is an incremental check-in pending further work. Leaf check-in: 00ac73a01c user: drh tags: tabfunc-in-left-join
00:44 Avoid unnecessary memset() operations in sqlite3PagerGet(). Leaf check-in: 0c97b80240 user: drh tags: pager-get-noinit

01:00 Change the code generator for UPDATE to generate code in an order that might run more efficiently in many cases. Leaf check-in: c6239bf943 user: drh tags: improved-update
03:34 Whenever two or more OP_Column opcodes on the same cursor occur in succession, try to reordering them so that the one that extracts the right-most column is first, so that it will warm up the row cache for all those that follow. This gives a small performance boost. Leaf check-in: 08e8f04d12 user: drh tags: reorder-column-opcodes

19:05 Only run the OP_OpenRead opcodes for a correlated subquery once, on the initial iteration. Keep the cursor open for subsequent runs. This was suppose to be a performance enhancement, but it is difficult to come up with a query where is makes a significant difference. Hence, the change is getting parked in a branch.
