20 check-ins using file src/func.c version 8c075dd8

2019-05-09
18:37
Fix another small buffer overread in sqlite_dbdata triggered by a corrupt database page. (check-in: 1dfc95b8 user: dan tags: trunk)
18:33
Fix a problem in the ".recover" command allowing a circular loop of b-tree pages in a database file to cause an infinite loop. (check-in: 8d2a062e user: dan tags: trunk)
18:13
Make the ".schema" command in the CLI resistant to corrupt database files. (check-in: f22c7e22 user: drh tags: trunk)
17:54
Fix a crash in the sqlite_dbdata module that could occur if a pointer within an overflow chain in a corrupt database pointed past the end of the db. (check-in: 3eae4e30 user: dan tags: trunk)
17:10
Disable the optimization where a REAL value with no fractional part is stored as an INTEGER when the integer uses as much space as the real value it proposes to stand in for (8 bytes). This avoids corner cases of comparing integers against real values that are beyond the resolution of an IEEE 754 double. Fix for ticket [6c1d3febc00b22d457c78c2] (check-in: 9b091527 user: drh tags: trunk)
16:57
Avoid long delays that can occur when ".recover"ing data from a database with a corrupt freelist. (check-in: 20f06bf2 user: dan tags: trunk)
16:22
Improved debugging output from the OP_MakeRecord opcode. (check-in: ac790729 user: drh tags: trunk)
15:51
Fix another corruption related buffer overread in the sqlite_dbdata module. (check-in: 5cd728fb user: dan tags: trunk)
15:07
Fix further buffer overreads triggered by passing corrupt records to the sqlite_dbdata module. (check-in: dbc6a9f7 user: dan tags: trunk)
14:15
Have ".recover" handle cases where the sqlite_master table contains malformed SQL statements. (check-in: e736da9c user: dan tags: trunk)
11:45
Fix a problem with running the ".recover" command on a database that is zero pages in size. (check-in: 47fa6534 user: dan tags: trunk)
11:34
Avoid reading outside a record buffer when extracting an SQL value in the sqlite_dbdata virtual table code. (check-in: d99bb0c1 user: dan tags: trunk)
11:21
Merge accidental fork in trunk. (check-in: ec937303 user: dan tags: trunk)
11:19
Fix a problem in the new code introduced by [658b84d7] causing corruption and other errors to be ignored. (check-in: 7ccf2e7d user: dan tags: trunk)
11:18
Improved error handling for the ".open --hexdb" command of the CLI. (check-in: 4fa831d5 user: drh tags: trunk)
2019-05-08
23:55
Ensure that the sqlite3BtreeLast() interface initializes the *pRes return to zero if the cursor is already sitting on the last entry of the table. Manuel Rigger found the obscure test case for which this makes a difference. (check-in: ebe4845c user: drh tags: trunk)
23:53
This is part of the previous check-in that didn't get committed for some reason - probably because I failed to press the "Save" button on the text editor. (check-in: 51d32173 user: drh tags: trunk)
21:14
Add another test case to cover a previously uncovered branch in the RBU module. (check-in: 30392985 user: dan tags: trunk)
19:55
Fix another pattern for which the LIKE optimization does not work for a non-TEXT affinity. Case found by Manuel Rigger. (check-in: 74020110 user: drh tags: trunk)
19:32
Simplification to the logic underlying PRAGMA case_sensitive_like. (check-in: ef0015fd user: drh tags: trunk)
