11 check-ins using file src/select.c version 47f6d9e1

2021-04-12
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)
