2020-07-03
12:32
Fix the pragma_foreign_key_check virtual table so that it accepts arguments. (check-in: 07f849de user: drh tags: trunk)
12:15
Fix a problem with "PRAGMA foreign_key_check" where if a table in one schema appears to have foreign key constraints against another table in a different schema, the pragma will try to check the constraints even though they do not apply because they are in different schemas. (check-in: 81bc4b65 user: drh tags: trunk)
2020-07-01
16:19
Ensure that the "PRAGMA schema_version" command causes the schema to be reparsed and reloaded. (check-in: 27d4a9a7 user: drh tags: trunk)
14:07
Fix a problem with VM code generated for some aggregate SELECT statements that feature min()/max() aggregates both with and without FILTER clauses. (check-in: 2094da75 user: dan tags: trunk)
2020-06-30
18:21
Add a test to ensure that "PRAGMA wal_checkpoint = FULL" invokes the busy-handler to wait on read-locks. (check-in: f068fb11 user: dan tags: trunk)

17:56
When computing the verification hash in speedtest1, do not include the value of floating point results (which can very in trailing bits depending on platform) but merely hash the fact that a floating point value was received. (check-in: e12225d5 user: drh tags: trunk)
16:17
Improvements to speedtest1.c for more consistent verification hashes. (check-in: d34b8ff5 user: drh tags: trunk)
15:42
Improvements to speedtest1. Added the --memdb and --output options. The --verify option now outputs a hash of SQL outputs. The speed-check.sh script disables the hashing feature with --legacy and adds the --verify option. (check-in: f3455cec user: drh tags: trunk)

Enhance the --verify option to speedtest1.c so that it computes and displays a hash of the result from all SQL queries, for verification purposes. (check-in: 60d1e46c user: drh tags: speedtest-hash)
2020-06-24
12:29

2020-06-23
20:03

13:51
Fix a defect in the query-flattener optimization identified by ticket [8f157e8010b22af0]. (check-in: 10fa79d0 user: drh tags: trunk)
2020-06-14
13:40
Check-in [1d4f86201dab9a22] changed a testcase() to an assert() because we didn't know how to reach that condition any more. But YongHeng's fuzzer found a way. So now we change it back. Ticket [9fb26d37cefaba40]. (check-in: 90b1169d user: drh tags: trunk)
2020-06-13
21:24
Avoid deleting expression nodes in the flattener code, as they may be referenced by AggInfo objects further up the stack. Ticket [e367f31901ea8700] (check-in: cc1fffde user: dan tags: trunk)
03:18
Identifiers "TRUE" and "FALSE" cannot take on their boolean constant values if they are operands of the "." operator. (check-in: ad738286 user: drh tags: trunk)

2020-06-10

11:01
Ensure that the "push-down" optimization does not push constraints down into compound queries if any of the component queries uses window functions. (check-in: d31850fe user: dan tags: branch-3.32)
10:58
Ensure that the "push-down" optimization does not push constraints down into compound queries if any of the component queries uses window functions. (check-in: 094dcfe7 user: dan tags: trunk)
2020-06-09
23:50
Ensure that aggregate functions that (a) are part of SELECT statements with no FROM clause and (b) have one or more scalar sub-selects as arguments are assigned to the correct aggregate context. Fix for ticket [7c6d876f84e6e7e2] (check-in: c29a9e48 user: drh tags: trunk)

(check-in: 6e6b3729 user: drh tags: trunk)
2020-06-07
20:18
AggInfo objects might be referenced even after the sqlite3Select() function that created them has exited. So AggInfo cannot be a stack variable. And it must not be freed until the Parse object is destroyed. (check-in: 3c840b4d user: drh tags: persist-agginfo)
17:33
Alternative fix to ticket [c8d3b9f0a750a529]: Prior to deleting or modifying an Expr not that is referenced by an AggInfo, modify the AggInfo to get its own copy of the original Expr. (check-in: 7682d8a7 user: drh tags: persist-agginfo)
00:51
Extra steps to ensure that queries that involve both window functions and aggregate functions are processed correctly by sqlite3WindowRewrite(). Fix for ticket [e5504e987e419fb0]. (Leaf check-in: 765bbcce user: drh tags: branch-3.32-early-winfunc-rewrite)

20:48
Merge multiple changes from trunk to address concerns with window-function parse-tree rewriting. (check-in: 05418b2a user: drh tags: branch-3.32-early-winfunc-rewrite)
19:35
When determining if the subquery inserted by the window-function rewriter is an aggregate query, aggregate functions that are in parameters to another window function do not count. Fix for ticket [1f6f353b684fc708] (check-in: 8583c348 user: drh tags: early-winfunc-rewrite-dev)
18:34
In the query flattener, defer deleting content until after associated Parse object is destroyed, in case some of the deleted expressions have been collected for use by sAggInfo. (check-in: 03b32be4 user: drh tags: early-winfunc-rewrite-dev)
14:44
When rewriting the parse-tree for window functions, ensure that the inserted subqueries have an accurate SF_Aggregate bit set. This change also coincidentally fixes ticket [0899cf62f597d7e7], even thought that was not the issue we were working on at the time. (check-in: 2cddb24e user: drh tags: early-winfunc-rewrite-dev)
14:29
Fix an assert() failure that could occur if an ORDER BY expression attached to a compound query contains a subquery that (a) is itself a compound query, (b) uses window functions and (c) has an ORDER BY clause that includes another sub-query. (check-in: c96914ea user: dan tags: early-winfunc-rewrite-dev)
2020-06-05
15:56

15:40
New test case for fuzzdata8.db. (check-in: 2870d117 user: drh tags: early-winfunc-rewrite-dev)
15:26
Do parse-tree transformations required for window functions prior to running aggregate function analysis. Fix for ticket [c8d3b9f0a750a529]. (check-in: 0b42a227 user: drh tags: early-winfunc-rewrite-dev)
14:53
Ensure that the "push-down" optimization does not push constraints down into compound queries if any of the component queries uses window functions. (Closed-Leaf check-in: 2011e832 user: dan tags: early-winfunc-rewrite)
00:54
Always use ?...? to indicate optional arguments in the output of ".help" in the CLI. Change ".mode column" so that it automatically activates ".headers on" if headers have not been previously turned on or off. (check-in: 2827c0a1 user: drh tags: trunk)
2020-06-04
18:05

2020-05-28
23:49
Progress toward adding new output modes to the CLI: json, table, and markdown. (check-in: 14f55faf user: drh tags: trunk)
00:45
When the sqlite_stat1 data is missing for some indexes of a table but is present for the table itself or for other indexes in the same table, then do not let the estimated number of rows in that table get too small, as doing so can deceive the query planner into ignoring a perfectly good index. (check-in: 98d42620 user: drh tags: trunk)
2020-05-25
18:18

2020-05-23
