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: c6fd70b3c2 user: drh tags: trunk)
18:15
Add a test for the fixes on this branch. (Closed-Leaf check-in: 716088d673 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: c623d9a51e user: drh tags: cleanup-testing)
17:05
Improvements to the ".testctrl fault_install" command in the CLI. (check-in: 48b34ded82 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: 1e8863909a user: drh tags: cleanup-testing)
09:26
Squelch two OMIT-flag-related warnings reported in [forum:388243d9882067a9|forum post 388243d9882067a9]. No functional changes. (check-in: 1d6716054d user: stephan tags: trunk)
2024-05-09
18:54
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:b549992634b55104|forum post b549992634b55104]. (Leaf check-in: ce2eb6d89a user: stephan tags: branch-3.45)
18:39
Add a maintenance-reminder comment explaining [dc58ed65492857]. (check-in: 857f5d7fad user: stephan tags: trunk)
18:00
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:b549992634b55104|forum post b549992634b55104]. (check-in: dc58ed6549 user: stephan tags: trunk)

Fix a problem causing the recovery extension to use excessive memory and CPU time in some cases. (check-in: bc394acb6e user: dan tags: branch-3.45)
2024-05-08
17:57
Rename a shadowed local var, as reported in [forum:2ba65af3148585cf|forum post 2ba65af31]. No functional changes. (check-in: d030c87c4d user: stephan tags: trunk)
17:42

19:45
Fix bug in test script sessionconflict.test. (check-in: e29decb8b1 user: dan tags: trunk)
17:58
Ensure successive scans of pragma virtual tables return consistent rowids. (check-in: 6838bf3ac1 user: dan tags: trunk)
13:20
Fix a compilation error in test/lemon-test01.y, reported in [forum:f0ad095705|forum post f0ad095705]. (check-in: 576b68c8b5 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: 2bf8c3f99a user: dan tags: trunk)
20:18
Omit redundant unary + operators from the AST. (check-in: f81cc149e5 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: 70abc144ca user: drh tags: trunk)
17:55
Add new sessions API sqlite3changegroup_add_change(). (check-in: 5eaab43ce4 user: dan tags: trunk)
17:32
Edit comments in sqlite3session.h. (Closed-Leaf check-in: 49f84878e2 user: dan tags: changegroup-add-change)
17:21
Add tests for sqlite3changegroup_add_change(). (check-in: 9d67bedc20 user: dan tags: changegroup-add-change)
11:27
Fix problem in sqlar_uncompress() when being used to extract symbolic links. (check-in: 4d90c3f179 user: dan tags: trunk)
2024-05-05
10:00
Add comment to the test/lemon-test01.y file indicating that it does not work and is for historical reference only. (check-in: 9bdf73a8d4 user: drh tags: trunk)
2024-05-04
21:10
Add new sessions API sqlite3changegroup_add_change(). (check-in: 73647db1dd user: dan tags: changegroup-add-change)
16:50
Add test cases to test/in7.test. No code changes. (check-in: 8c3086f9fe 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: b36d499e4c 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: f16b200f25 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: 2f9fba931d 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: cdd1610c44 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: 26b2d9390f user: dan tags: trunk)
18:16
Avoid an assert failure accessible only when internal testing features are enabled. dbsqlfuzz crash-66abacda6bca6bd531e25595e8c8068e2c710326.txt. (check-in: fbc446daac user: dan tags: trunk)
17:46
Fix a case where the recovery extension might write uninitialized data to the recovered database. (check-in: 8519b4d039 user: dan tags: trunk)
14:48
Avoid an OP_Next in cases where an IN(...) query against a UNIQUE index may return at most 1 row. (check-in: d7648e2160 user: dan tags: trunk)
12:14
Fix the CREATE TABLE performance issue described by [forum:/forumpost/4cf69794d9dfff7c|forum thread 4cf69794d9dfff7c] in two different ways: (1) Omit the call to PRAGMA integrity_check('X') that was being done after CREATE TABLE "X" because the result was being ignored and the integrity_check was not doing anything other than burning CPU cycles. (2) Do not interpret the argument to PRAGMA integrity_check as a number if it is in fact a string that looks like a number. (check-in: 71f08b9122 user: drh tags: trunk)
12:00
Add a test case to the fix to PRAGMA integrity_check in the previous check-in. (Closed-Leaf check-in: 39a57b596d user: drh tags: faster-create)
11:52
Do not accept a string that looks like a number used as an argument to PRAGMA integrity_check as a number. Treat it as a table name that just happens to look like a number. (check-in: b04e7a2347 user: drh tags: faster-create)
11:51
Omit the OP_SqlExec to "PRAGMA integrity_check" added by [348fa7aaf7958b3f] because it is a no-op. Even if the integrity_check failes, the CREATE TABLE is stull successful. The OP_SqlExec just burns CPU cycles for no reason. (check-in: 532795acd1 user: drh tags: faster-create)
2024-05-01
19:48
Avoid an OP_Next in cases where an IN(...) query against a UNIQUE index may return at most 1 row. (Closed-Leaf check-in: 560f64157d user: dan tags: unique-in-opt)
16:25
Fix another problem in the recovery extension where a corrupt sqlite_schema table could lead to excessive memory consumption. (check-in: 1c7e33a8aa user: dan tags: trunk)
14:42
Fix a problem causing the recovery extension to use excessive memory and CPU time in some cases. (check-in: 8de85170d5 user: dan tags: trunk)
2024-04-30
19:34
Avoid 32-bit overflow when calculating ncycle for ".scanstats vm". (check-in: 2858efa06d user: dan tags: trunk)
2024-04-26
19:10
Fix issues in [/info/1e227ad9f413227f|LIMIT/OFFSET support for virtual tables]. The first problem was reported by [forum:/forumpost/c243b8f856|forum post c243b8f856]. That report prompted an enhancement to the generate_series() (also included in this merge) which in turn identified other similar issues. (check-in: 5f6c079d84 user: drh tags: trunk)
18:42
Internal JS doc touchups. No functional changes. (check-in: 626b997b4e user: stephan tags: trunk)
18:24
Additional internal docs in the wasm utilities. (check-in: 5a2245a9eb user: stephan tags: trunk)
18:13
Allow virtual table implementations to handle OFFSET but not LIMIT, but not LIMIT but not OFFSET. (Closed-Leaf check-in: 90e5c8226a user: dan tags: vtab-limit-fix)
17:19
Have where.c ignore any plan from a virtual table that tries to use LIMIT/OFFSET without also using all WHERE constraints. (check-in: 7d30596496 user: dan tags: vtab-limit-fix)
