50 check-ins occurring around 66c24513c2f6de98.

2018-06-05
23:51
Update the version number to 3.25.0 for the next development cycle. check-in: 7598236c35 user: drh tags: trunk
23:21
Avoid unnecessary loads of columns in an aggregate query that are not within an aggregate function and that are not part of the GROUP BY clause. check-in: e15e100660 user: drh tags: trunk
20:45
Add the OP_IfNoHope and OP_SeekHit opcodes used to reduce the number of unnecessary sqlite3BtreeMovetoUnpacked() calls when checking for an early exit on IN-operator loops. Futher optimizations are likely possible here. check-in: 6bf251af43 user: drh tags: multikey-opt-idea
20:04
Calculate non-aggregate expressions in the SELECT list of an aggregate query that does not use min() or max() once per group, instead of once per row visited. Closed-Leaf check-in: dce2dfbe15 user: dan tags: exp-agg-opt
16:16
Add implementation of last_value() window function. check-in: 2493ce1a40 user: dan tags: exp-window-functions
15:16
Use an OP_NotFound opcode to cancel futile IN operators early. The current implementation is suboptimal because it always runs teh OP_NotFound. This still needs to be enhanced to only do the OP_NotFound if no results have been seen on the current loop. check-in: 87a9fc504f user: drh tags: multikey-opt-idea
13:54
Merge trunk changes. check-in: 047295c588 user: drh tags: multikey-opt-idea
13:43
Update and correct the documentation on the OP_OpenRead, OP_OpenWrite, and OP_ReopenIdx opcodes. No code changes other than the addition of an assert(). check-in: 8a0b730d0e user: drh tags: trunk
2018-06-04
19:24
Version 3.24.0 check-in: c7ee083322 user: drh tags: trunk, release, version-3.24.0
18:55
Add implementation of window function ntile(). check-in: 3f093f608c user: dan tags: exp-window-functions
14:10
Merge changes from trunk. check-in: 95fbac39ba user: drh tags: apple-osx

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

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
2018-06-01
21:00
Allow an entire partition to be cached in a temp table for all types of window frames. This is required by nth_value() and others. check-in: b5b18f6613 user: dan tags: exp-window-functions
13:30
Fix a bug in the SQLITE_ENABLE_SORTER_REFERENCES code causing an out-of-bounds array reference. check-in: 8cadaf587d user: dan tags: trunk
2018-05-31
19:14

Add the Makefile.fallback makefile to the amalgamation tarball. check-in: ce3d045633 user: drh tags: trunk
07:36

07:24
Fix a typo in an error message in the CLI. check-in: 8088398081 user: drh tags: trunk
01:14
Fix the parser so that it builds with -DSQLITE_OMIT_CTE. check-in: 86ee267ee8 user: drh tags: trunk
00:59
Fix a harmless compiler warning. check-in: 8d02c7a6a0 user: drh tags: trunk
00:54
Demonstration code on a possible technique for optimizing the use of IN operator on columns to the right of multicolumn indexes. If the OP_Noop generated where were really a new opcode that checked to see if there existed any entries in the index with a matching prefix, it might prevent unnecessary iterations of the IN operator. check-in: 92f0fe155d user: drh tags: multikey-opt-idea
2018-05-29
19:12
Increase the number of database handles opened by test script oserror.test to provoke an "out of file-descriptors" error to 20000 (from 2000). check-in: 3b00f73456 user: dan tags: trunk

15:18
Add a comment to justify a goto statement. No code changes. check-in: f141d80647 user: drh tags: trunk
14:29
More minor changes to test scripts. check-in: ce9b756f09 user: dan tags: trunk

13:25
Do not run test file "resetdb.test" as part of permutation "inmemory_journal". check-in: 4921e5bae4 user: dan tags: trunk
2018-05-28
23:59
The geopoly virtual table seems to be working. But only thinly tested so far. check-in: 4288f1ad59 user: drh tags: rtree-geopoly
18:30
Further window frame tests and fixes. check-in: e74c6e9185 user: dan tags: exp-window-functions
18:29
Do not require a statement journal in cases where REPLACE conflict handling is used to insert a single row, so long as the REPLACE operation cannot fire any triggers or foreign key actions. check-in: 469a62ca33 user: dan tags: trunk
18:25
When compiling with SQLITE_DEBUG, add run-time checks to ensure that no statement aborts unless either there have been no writes or else there is a statement journal. check-in: ce99c77244 user: drh tags: trunk
17:43

2018-05-26
21:17
