Do not attempt to limit the number of columns used in a table to a prefix if the table will be used to construct an automatic index or bloom filter. dbsqlfuzz 787d9bd73164c6f0c85469e2e48b2aff19af6938. (check-in: f8766231 user: drh tags: trunk)
14:14
CLI: Enhancements to columnar output modes. (See [forum/forumpost/5b53cd851f66441f9|forum post 5b53cd851] for discussion.) New output mode "qbox". New output options "--quote" and "--wrap N". (check-in: 539cef52 user: drh tags: trunk)

2022-01-30
21:09
CLI: For columnar modes ("box", "column", "table", "markdown") the ".width" is now both the minimum and maximum width of the column. Text that spans multiple lines or that contains tabs is properly formatted. If any part of the output contains multi-line text, then extra separators are provided between each row. (check-in: c10ed4a7 user: drh tags: trunk)
11:44
Always enable all JSON tests, now that JSON is included by default. (check-in: 8c9f3501 user: drh tags: trunk)

13:18
Enable SQLITE_INDEX_CONSTRAINT_LIMIT/OFFSET even if there are vector comparison operators in the WHERE clause. Also: Do not enable sqlite3_vtab_rhs_value() for LIMIT/OFFSET if the value is negative, as this violates an invariant on Expr.u.iValue. (check-in: 140480b3 user: drh tags: vtab-limit-offset)
2022-01-27
21:18
Query planner always honors the aConstraintUsage[].omit flag for the SQLITE_INDEX_CONSTRAINT_OFFSET constraint. (check-in: 38c5151e user: drh tags: vtab-limit-offset)

13:52
Enforce the restriction that 'unixepoch' only works as the first modifier after the time-value. This has been documented since 2004, but has never actually been enforced before. Also add new test cases for date/time functions with evidence marks. (check-in: 64fa9e8c user: drh tags: trunk)
2022-01-25

One of the ALWAYS() macros in the previous check-in could sometimes be false, following an OOM. Remove it. Problem found by dbsqlfuzz. (check-in: 11df9187 user: drh tags: trunk)
19:38
Add ALWAYS() macros. Change some existing ALWAYS() into assert(). Other code simplifications. (check-in: 4aa27b4f user: drh tags: trunk)
16:47
Remove many redundant checks for sqlite3.mallocFailed now that any OOM should cause Parse.nErr to be non-zero. (check-in: 1f7fa461 user: drh tags: trunk)
15:34
Make it so that any Parse object is always linked into the database conenction while it is active. Hence, an OOM will cause Parse.nErr to be set. (check-in: 6a45d8fe user: drh tags: trunk)
14:01
Fix testcase for CLI .read recursion. (check-in: 53d44044 user: larrybr tags: trunk)
12:48
Make sure the sqlite3OomFault() routine sets an error in the Parse object if there is a Parse object active and linked to the database connection. (check-in: ad7aace7 user: drh tags: trunk)
11:25
Ensure that any error encountered while coding a trigger program is transfered to the main Parse structure before it is used with any other routine that might set the error code. (check-in: 42936565 user: dan tags: trunk)
07:11
Take CLI input redirect recursion limit from trunk (check-in: 5e702044 user: larrybr tags: shell-tweaks)

2022-01-22
22:28
Add support for the sqlite3_vtab_distinct() interface. Virtual table implementations can use this API to determine more detail about the ordering requirements needed by the query plan and perhaps reduce the amount of work required to compute a correct answer. This is an optimization opportunity for the virtual table implementation. The correct answer should still be obtained (though perhaps more slowly) even if sqlite3_vtab_distinct() is ignored. (check-in: e4caf1e3 user: drh tags: trunk)
20:45
Bring sqlite3_vtab_distinct() up to spec so that it works as described in the documentation. (Closed-Leaf check-in: 4289edf3 user: drh tags: sqlite3_vtab_distinct)

Omit the WhereLoopBuilder.pOrderBy field, which is no longer needed. (check-in: a13afc90 user: drh tags: sqlite3_vtab_distinct)
00:18
An initial attempt to implement sqlite3_vtab_distinct(). (check-in: d571262d user: drh tags: sqlite3_vtab_distinct)
2022-01-21
19:26
Update evidence marks for the latest changes to the documentation. (check-in: 19247e91 user: drh tags: trunk)
18:57
Fix some of the new date/time function features to comply with the spec. Update requirement marks. (check-in: 2f5dc7a9 user: drh tags: trunk)
16:47
When computing a vector to be used as a key for an index lookup, do not check for NULL values and abort until after all key values have been computed, in case one of the later key values involves some initialization that is needed by a LEFT JOIN. Fix for the problem identified by Forum post ab95010d410a0a55. (Leaf check-in: 3bc8d162 user: drh tags: branch-3.37)
16:41

17:10
Initial implementation of the sqlite3_vtab_rhs_value() interface and the qpvtab extension used for testing the virtual table interface. (check-in: 0873c76b user: drh tags: sqlite3_vtab_rhs_value)
14:51
A better and more robust fix for the problem of reading a read-only WAL mode database with existing -wal and -shm files, replacing [f426874e005e3c23]. (check-in: 1266220a user: drh tags: branch-3.37)
14:40

.ar fixed and constituent line numbers off (until they are right) (check-in: ec363f81 user: larrybr tags: cli_extension)
15:23
Fix incorrect testcase() and assert() macros in json.c. They were not causing problems. The assert() was simply unreachable. The testcase() added an unreachable condition. (check-in: 5623497a user: drh tags: trunk)
14:42
Never allow the b-tree layers view of the number of pages in the database file exceed the actual number of pages in the database file, even when PRAGMA writeable_schema=ON.

Add --schema S option to .import (check-in: 38d9dbca user: larrybr tags: trunk)
2022-01-12
20:31
When the result of a subquery is to be stored in a register and that subquery has an ORDER BY clause and an OFFSET, NULL out the destination register before starting the ORDER BY so that the register will be set correctly even if the OFFSET is larger than the number of output rows. Fix for the problem reported in forum post 0ec80f12d02acb3f. (check-in: 9282bcde user: drh tags: trunk)
01:42
