13:20
The SQLITE_NoSchemaError flag should not apply to OOM errors while parsing the schema. (check-in: 9cc484ad user: drh tags: trunk)
13:01
Earlier detection empty_result_callbacks in sqlite3InitCallbac() to avoid problems with corrupt schemas an writable_schema=ON. dbsqlfuzz ca4ca43bdb22eab9859de4979aec615af851e111. (check-in: fb305fe0 user: drh tags: trunk)
12:28
In the rtreedepth() function, detect OOM when converting a zeroblob() on input. dbsqlfuzz ed23eda7cc3a8a054f85ea19d55c59ba2ca72744. (check-in: 69f843c8 user: drh tags: trunk)
01:12
Fix an error in the inversion function for json_group_array(). dbsqlfuzz 68a4b0f668b7bc27235e3f1c5cff8a2d94cfa17e. (check-in: e718a62e user: drh tags: trunk)
2021-04-12
23:18
Fix a faulty assert() inside sqlite3ExprDup(). (check-in: 59812e7e user: drh tags: trunk)
22:39
Fix an assert() in OP_ParseSchema so that it works even after an OOM. (check-in: 79b88353 user: drh tags: trunk)
18:32
Avoid taking the address of a NULL pointer following an OOM in FTS5. Doing so is harmless in actual practice, but it technically UB so we want to avoid it. (check-in: 1cfcd9dc user: drh tags: trunk)
17:34
Add an assert() to show that the SF_Resolved flag does not get set if errors are being suppressed. (check-in: f455c5b0 user: drh tags: trunk)
16:59
Fix a segfault that could occur if the ORDER BY clause of a compound SELECT contains a sub-select that uses one or more window functions. (check-in: 5ba15ebb user: dan tags: trunk)
12:58
Fix the display of SrcList in the sqlite3TreeView debugging routines. (check-in: 28ecb381 user: drh tags: trunk)
12:02
Avoid an assert() failure when a compound scalar sub-select is, due to a "WHERE (sub-select) AND (... OR ...)" clause, coded twice by the code generator. (check-in: a4e3f133 user: dan tags: trunk)
11:51
Fix harmless comment typo in main.c. (check-in: 785a553e user: drh tags: trunk)
2021-04-11
00:11
Add NEVER() to a branch that is no longer reachable due to check-in [a1d823f6879ce1ac]. (check-in: 5fda21fe user: drh tags: trunk)
2021-04-10
20:27
Avoid an uninitialized-memory valgrind error by tightening up corruption detection in internal routine defragmentPage(). (check-in: 8096f7ae user: dan tags: trunk)
20:21
Add NEVER() to a branch that became unreachable with check-in [58f36af2271517ab]. (check-in: e07ce463 user: drh tags: trunk)
15:34
Avoid invoking sqlite3Atoi64() will a null pointer following an error from ExpandBlob(). (check-in: 780412f2 user: drh tags: trunk)
14:49
Fix a problem with handling expressions like "(col IS NULL AND <expr1>) OR col == NULL" in WHERE clauses. Reported at https://sqlite.org/forum/forumpost/1c4f2fdcc4. (check-in: 40852ca8 user: dan tags: trunk)
13:37
Refactor NameContext.nErr into nNcErr to avoid confusion with Parse.nErr. Do not abandon sqlite3ResolveExprList() on nNcErr if nErr is still zero as we might have hit a problem with ORDER BY resolution that should be a suppressed error. dbsqlfuzz 41b9dad40919d3549ca7e52d893da81a6dded4ad (check-in: 7d674970 user: drh tags: trunk)
2021-04-09
22:34
Remove a NEVER() in a corruption detection conditional in defragmentPage(). dbsqlfuzz 9c61c33802600b2b01dfb09b0386ceb4ade02a19 (check-in: c174f5d3 user: drh tags: trunk)
22:20
Remove an ALWAYS() that is actually reachable following an OOM on an UPDATE FROM of a virtual table. dbsqlfuzz aa03237ef7c4a028c7cdaf8bbcde2b62e2bcd36e (check-in: 49eac389 user: drh tags: trunk)
20:50
Have the VFS in memdb.c return SQLITE_IOERR_NOMEM instead of SQLITE_NOMEM when an OOM error is encountered. This is required to get the pager module to handle such OOM errors correctly in some cases. (check-in: 09c96b4c user: dan tags: trunk)
2021-04-08
20:29
Fix a use-after-free error that could occur when processing "SELECT aggregate(DISTINCT <expr>)..." queries. (check-in: 0e478986 user: dan tags: trunk)
19:56
Remove an ALWAYS() that might be false under very unusual circumstances. dbsqlfuzz 300261f469ace7ecc57ed32ea7b0de3ea9d7dbf. Test case in TH3. (check-in: 466f5089 user: drh tags: trunk)
19:39
Handle the corruption fixed by the previous commit in a different way so as to also fix dbsqlfuzz crash 753de0a0ac5b25b18f1e4d41e650d3333cdc270c. (check-in: cb27ce25 user: dan tags: trunk)
15:19
Handle a special case of corruption that can present if "PRAGMA writable_schema=1" is set. Fix for dbsqlfuzz test case 6229ad63de49e3ba0630aaf0058868f36008bcca. (check-in: 58f36af2 user: dan tags: trunk)
14:15
Harden the filter_over grammar rule against OOM faults. dbsqlfuzz e47c54502a9c36778a5ed553199d5870e2ebd9f2 (check-in: f375f541 user: drh tags: trunk)
13:52
Remove an incorrect assert() from sqlite3EndTable(). dbsqlfuzz 4af45bcda779592449b1985433bca90b0e683b9b. (check-in: 38a1085c user: drh tags: trunk)
