21:04
Add support for window functions row_number(), rank(), dense_rank() and percent_rank(). (check-in: 91c1cb7a21 user: dan tags: exp-window-functions)
19:14
Avoid using a misaligned pointer. (check-in: 1ecb3aa13d user: drh tags: trunk)
19:01
Fix the usage of posix_fallocate() so that it correctly responds to EINVAL returns. (check-in: ce2c3e7a87 user: drh tags: trunk)
17:00
Update a test case in malloc5.test to take into account that malloc() sometimes returns slightly more space than requested. (check-in: 3d5eae1c26 user: dan tags: trunk)
16:32
Work around a sanitizer warning about a pointer being only 4-byte aligned instead of 8-byte aligned. (Closed-Leaf check-in: 1b807b51cd user: drh tags: align8-fix)
14:37
Proposed fix for the use of posix_fallocate() so that it handles EINVAL returns correctly. (Closed-Leaf check-in: ab3a5539db user: drh tags: einval-from-fallocate)
12:05
Fix the CSV extension so that it works with single-column CSV files. (check-in: e336cf0048 user: drh tags: trunk)
11:31
Ensure that sqlite3AuthRead() is only call for TK_COLUMN and TK_TRIGGER expression nodes. This fixes a harmless assert() identified by OSSFuzz. Move the assert() into a position where it is tested even if the authorizer is disabled. (check-in: d0c3beef7c user: drh tags: trunk)

Add the --fsync flag to kvtest, and document the --nosync flag. (check-in: 7fdc78a672 user: drh tags: trunk)
19:31
Work toward enhancing kvtest to measure write performance. (check-in: fc73e7d2f1 user: drh tags: trunk)
15:44
Change the name of the OP_Seek opcode into OP_DeferredSeek for better clarity of function. No functional code changes. (check-in: ab33d299c7 user: drh tags: trunk)
13:16
Fix a typo in the header comment of the "series.c" virtual table extension. (check-in: d637feb4e3 user: drh tags: trunk)
09:31
Extend even further the logging designed to find problems in the pointer-map structure. Call abort() to dump a core as soon as such a problem is seen. (check-in: f131677dcb user: dan tags: begin-concurrent)

23:13
Add the CSV extension to the test fixture. Fix a memory leak in the CSV extension. Add test cases for the CSV extension, including one that uses a WITHOUT ROWID virtual table participating in the OR optimization. (check-in: 95f483e86e user: drh tags: without-rowid-vtab)
17:44
Add the data= parameter to the CSV virtual table extension. (check-in: 769191042a user: drh tags: without-rowid-vtab)
16:22
Fix corner cases in the WITHOUT ROWID virtual table logic. (check-in: a393bbb972 user: drh tags: without-rowid-vtab)

19:38
Change the fts5 multi-column syntax to use parenthesis instead of square brackets. (check-in: ab85a6fc4f user: dan tags: fts5)
19:36
Always check for cell overflow before returning a slot from the pageFindSlot routine in btree.c. (check-in: 9f035c45a4 user: drh tags: trunk)
18:09
For FROM-clause subqueries that cannot be flattened, try to push relevant WHERE clause terms of the outer query down into the subquery in order to help the subquery run faster and/or use less memory. Call this the "WHERE-clause push-down optimization". Do not confuse this with the completely different MySQL push-down optimization. (check-in: 6df18e949d user: drh tags: trunk)
18:07
Merge latest trunk changes with this branch. (check-in: c9ffda4abb user: dan tags: fts5)
17:57
Reimplement [ec69e09a] so that each call to the xNext() method does not involve two iterations of the match expression tree (only one). (check-in: 80fe305b3e user: dan tags: fts5)
17:25
Add test cases for type affinity rules. (check-in: 9678646d9a user: drh tags: trunk)
16:50 Edit [bce3f04186cd2d69|bce3f04186]: Mark "Closed". (artifact: 0ff1100a27 user: drh)
16:19
Rename SQLITE_AFF_NONE to SQLITE_AFF_BLOB to avoid confusion with "no affinity". (check-in: 29ad9e9173 user: drh tags: trunk)
16:09
Add the built-in affinity() SQL function. This turns out to be not as useful as originally envisioned, so abandon it on a branch. (Leaf check-in: 80889306bf user: drh tags: affinity-func)
15:32
Rename SQLITE_AFF_NONE to SQLITE_AFF_BLOB. (Closed-Leaf check-in: bce3f04186 user: drh tags: blob-affinity-rename)
14:02
Fix a faulty assert() in btree.c. Update the database fuzz test file with new test cases. (check-in: 4e621af134 user: drh tags: trunk)
09:20
Add the "finish_test" command to the end of new test script sessionE.test. (check-in: fb39140707 user: dan tags: sessions)
09:19
Modify the sessions module to ignore all operations on tables with no primary keys as documented. (check-in: bdaf9575cd user: dan tags: sessions)

Remove the WHERE_LIKELIHOOD bit, as it does not seem to effect any result. (check-in: 1cbe7a0883 user: drh tags: trunk)

Fix a typo in a requirements mark comment in a test script. No changes to code. (check-in: 75ff459b06 user: drh tags: trunk)
11:26
Fix the query planner so that it once again knows that queries without a FROM clause will never return more than one row and hence do not require sorting. (check-in: 9f18b303cd user: drh tags: trunk)
09:39
Add the "valgrind-nolookaside" permutation to permutations.test. (check-in: 8e8472d9b6 user: dan tags: trunk)

Add the vdbe-compress.tcl script which automatically refactors the sqlite3VdbeExec() routine to use less stack space. Use this script when constructing the amalgamation. (CVS 6704) (check-in: 7f43391831 user: drh tags: trunk)
