Fix the definition of sqlite3_vtab_distinct() such that return codes 2 and 3 mean that all rows must be distinct over "colUsed" which is a superset of "aOrderBy". Also, disallow return codes 2 and 3 if the rowid of the virtual table is accessed. (Leaf check-in: 922731ce user: drh tags: vtab-distinct-fix)
15:21
JS error message and doc typos reported in the forum. No code changes. (Leaf check-in: 1a073f9a user: stephan tags: trunk)

Merge branches "fix-onerow-opt", "faster-openread", "fts5-delay-tokenizer" and "enhanced-raise", each containing minor enhancements prepared for 3.46, into this branch. (Leaf check-in: 6dc64721 user: dan tags: pending-3.46)
13:56
Fix a problem in where.c preventing SQLite from identifying some ONEROW scans, leading to (slightly) sub-optimal byte-code. (Closed-Leaf check-in: b41e7120 user: dan tags: fix-onerow-opt)
2024-05-16
16:22
Add extra tests for the error messages generated by sqlite3_declare_vtab() when passed something other than a well-formed CREATE TABLE statement. (check-in: 5fa0c2a0 user: dan tags: trunk)
15:57
The sqlite3_declare_vtab() interface should return SQLITE_ERROR, not SQLITE_MISUSE when a nonsense SQL input is provided, for legacy compatibility. Forum post 4b875d7b2a. (check-in: 1ec2961a user: drh tags: trunk)
00:20
Fix a case where an error in the ORDER BY clause of an aggregate function that is part of a trigger body might cause an assert() to fail in an ALTER TABLE command. dbsqlfuzz 899d9255555a07f1fe11a0bb51a2fe197b3150cd (check-in: 953271f2 user: drh tags: trunk)

23:36
Back out the assert() fixes from [a9443dbfbe25e588] and [3afaeac56dff58db] (but keep the corresponding test cases) because they are both made obsolete by the previous fix on this branch. (Closed-Leaf check-in: 3120c7c8 user: drh tags: alter-table-fix)
21:38
Fix a case where an error in the ORDER BY clause of an aggregate function that is part of a trigger body might cause an assert() to fail in an ALTER TABLE command. (check-in: b79a8be3 user: dan tags: alter-table-fix)
15:11
If there is no data available for a field in a corrupted record, but the type is available, have the recovery extension substitute 0, 0.0, '' or X'' instead of a NULL value. (Leaf check-in: 78051359 user: dan tags: branch-3.45)
15:06
If there is no data available for a field in a corrupted record, but the type is available, have the recovery extension substitute 0, 0.0, '' or X'' instead of a NULL value. (check-in: 8eb326c2 user: dan tags: trunk)

Optimize queries against fts5vocab(row) tables that do use the "cnt" column. (Closed-Leaf check-in: 96a591c2 user: dan tags: fts5-delay-tokenizer)
19:09
Avoid calculating the value of the "cnt" column for fts5vocab(row) queries that do not use it. (check-in: c0c91e30 user: dan tags: fts5-delay-tokenizer)
17:16
Have fts5 tables delay initializing the tokenizer until it is first used in all cases where the tokenizer is not "trigram". (check-in: ca4fdcb8 user: dan tags: fts5-delay-tokenizer)
2024-05-13
20:06
Allow existing fts5 tables to be dropped even if the associated tokenizer is not available. (check-in: 69ef47ee user: dan tags: fts5-delay-tokenizer)
2024-05-12

Add tests to bestindexC.test. No changes to code. (check-in: 58d938c0 user: dan tags: trunk)
2024-05-10
18:24
Fix aggregate function processing to correctly deal with OOMs inside of sqlite3ParserAddCleanup(). (dbsqlfuzz b2d11ca70e55ee8bde48ae0b53fa3e9355812f95). Also add improved testing support by causing sqlite3FaultSim(300) to simulate an OOM inside of sqlite3ParserAddCleanup() and by adding improved fault-sim support to the CLI. (check-in: c6fd70b3 user: drh tags: trunk)
18:15
Add a test for the fixes on this branch. (Closed-Leaf check-in: 716088d6 user: dan tags: cleanup-testing)
18:10
The sqlite3FaultSim(300) error from [1e8863909ac369e5] must be treated as an OOM, since it simulates an OOM. Also fix deferred deletion of Expr objects from [a53bdd311c4154fd] so that it does not corrupt the AST if an OOM occurs. (check-in: c623d9a5 user: drh tags: cleanup-testing)
17:05
Improvements to the ".testctrl fault_install" command in the CLI. (check-in: 48b34ded user: drh tags: cleanup-testing)
16:28
Add an sqlite3FaultSim(300) call to the sqlite3ParserAddCleanup() routine for more precise simulation of OOM errors in that routine. (check-in: 1e886390 user: drh tags: cleanup-testing)
09:26
Squelch two OMIT-flag-related warnings reported in forum post 388243d9882067a9. No functional changes. (check-in: 1d671605 user: stephan tags: trunk)

Reformulate a for-in loop to a for loop in wasm.xWrap() to work around downstream frameworks modifying the JS Array prototype, as reported in forum post b549992634b55104. (check-in: ce2eb6d8 user: stephan tags: branch-3.45)
18:39
Add a maintenance-reminder comment explaining [dc58ed65492857]. (check-in: 857f5d7f user: stephan tags: trunk)
18:00

Ensure successive scans of pragma virtual tables return consistent rowids. (check-in: 6838bf3a user: dan tags: trunk)
13:20
Fix a compilation error in test/lemon-test01.y, reported in forum post f0ad095705. (check-in: 576b68c8 user: stephan tags: trunk)
2024-05-06
20:21
When extracting links from sqlar archives, clobber any existing file or link, and do not call utimes() to set the timestamp - it looks through the link and operates on the target. (check-in: 2bf8c3f9 user: dan tags: trunk)
20:18
Omit redundant unary + operators from the AST. (check-in: f81cc149 user: drh tags: trunk)
19:04
Avoid unnecessary recursion in sqlite3ExprDeleteNN(). This complicates the code, but it is needed to prevent nuisance "stack overflow" reports from OSSFuzz while it is running the latest ASAN. (check-in: 70abc144 user: drh tags: trunk)
17:55
Add new sessions API sqlite3changegroup_add_change(). (check-in: 5eaab43c user: dan tags: trunk)

Add comment to the test/lemon-test01.y file indicating that it does not work and is for historical reference only. (check-in: 9bdf73a8 user: drh tags: trunk)
2024-05-04
21:10
Add new sessions API sqlite3changegroup_add_change(). (check-in: 73647db1 user: dan tags: changegroup-add-change)
16:50
Add test cases to test/in7.test. No code changes. (check-in: 8c3086f9 user: dan tags: trunk)
15:10
Assume that an SQL function is able to return a subtype if any of its arguments are SQL functions that are able to return subtypes. This closes a corner-case hole in the patch at [ba789a7804ab96d8]. (check-in: b36d499e user: drh tags: trunk)
15:04
Assume that a function is able to return a subtype if either (1) it is itself marked with SQLITE_RESULT_SUBTYPE, or (2) one of its arguments is a function that is able to return a subtype. This check-in backs out the code changes from the previous two on this same branch, but keeps the test cases from the previous two. (Closed-Leaf check-in: f16b200f user: drh tags: func-rw-subtype)
11:31
Functions that pass through the sqlite3_value of one of their arguments must also be marked as SQLITE_RESULT_SUBTYPE, in case one of their arguments has a subtype. (check-in: 2f9fba93 user: drh tags: func-rw-subtype)
2024-05-03
19:35
The coalesce(), ifnull(), and iif() functions pass through subtype values from their arguments, and hence need to have the SQLITE_RESULT_SUBTYPE flag set. (check-in: cdd1610c user: drh tags: func-rw-subtype)
2024-05-02
19:22
Fix a problem with queries that use "IN(...) ORDER BY ... NULLS LAST" or similar introduced by [d7648e21605a0b38]. (check-in: 26b2d939 user: dan tags: trunk)
18:16
Avoid an assert failure accessible only when internal testing features are enabled. dbsqlfuzz crash-66abacda6bca6bd531e25595e8c8068e2c710326.txt. (check-in: fbc446da user: dan tags: trunk)
