48 check-ins using file test/index6.test version 448fa05f

2019-05-10
20:44

17:54
Fix harmless compiler warnings. check-in: 956ca2a4 user: drh tags: trunk
17:50
Fix harmless compiler warnings in the CLI. check-in: 2846bc04 user: drh tags: trunk
16:16
Fix some harmless compiler warnings. Closed-Leaf check-in: ca068d82 user: mistachkin tags: warnings
14:34
Ensure that the BtShared.nPage value is reset correctly on a SAVEPOINT ROLLBACK. check-in: e6d5fee8 user: drh tags: trunk
14:26
Treat integer values in window definition ORDER BY clauses as constants, not as references to another expression. check-in: 7e4809ea user: dan tags: trunk
14:03
Improved comments and extra assert() statements on the OP_Savepoint opcode, just to make the code a little easier to read and reason about. check-in: e80b2d9f user: drh tags: trunk
12:14
Fix the previous check-in [db9acef14d492121] so that the amalgamation build works for systems for which lack HAVE_ISNAN. check-in: 3cc55e09 user: drh tags: trunk
12:06
Fix the round() SQL function so that it handles infinities correctly. check-in: db9acef1 user: drh tags: trunk
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
19:06
Avoid an excess register allocation in UPDATE, when possible. This improves speed (slightly) and reduces the code footprint. check-in: 8658574e user: drh tags: trunk
18:49
Add tests to improve code coverage of the RBU module. check-in: ecb56b75 user: dan tags: trunk
17:27
Provide the SQLITE_OMIT_CASE_SENSITIVE_LIKE_PRAGMA compile-time option to omit the case_sensitive_like pragma. This change, in combination with documentation changes, is the current solution to ticket [a340eef47b0cad5]. check-in: eabe7f2d user: drh tags: trunk
11:52
Fix VDBE opcodes OP_SeekLT and OP_SeekLE so that they work on intkey tables with non-numeric text values. Fix for [9cf6c9bb]. check-in: 658b84d7 user: dan tags: trunk
11:42
Fix VDBE opcodes OP_SeekLT and OP_SeekLE so that they work on intkey tables with non-numeric text values. Closed-Leaf check-in: a870c196 user: dan tags: tkt-9cf6c9bb
04:33
Remove an ALWAYS() that was previously added by check-in [a0819086] but which turns out can sometimes be false. check-in: ad8fc5d8 user: drh tags: trunk
03:34
Remove a NEVER() that was added in the previous check-in [a0819086a521f] because it is in fact reachable. check-in: 74eba255 user: drh tags: trunk
00:17
Earlier detections of errors in the byte-offset-to-cell-content integer at offset 5 in the header of a btree page. check-in: a0819086 user: drh tags: trunk
2019-05-07
20:06
Generate all records for INSERT or UPDATE prior to running foreign key constraint checks, since the FK checks might modify the datatype of registers used to generate the records. Fix for ticket [e63cbcfd3378afe6980d6]. check-in: 3c75605b user: drh tags: trunk
19:44
Do not commit an "OR FAIL" statement that causes foriegn key constraint violations. check-in: 659c551d user: dan tags: trunk
19:21
Add test cases for the fix on this branch. Closed-Leaf check-in: 2e31abe0 user: dan tags: tkt-e63cbcfd
19:13
On an INSERT or UPDATE, generate the new table record prior to running foreign key checks, in case the foreign key checks changes datatypes on the registers holding column values. Proposed fix for ticket [e63cbcfd3378afe6980d626]. check-in: 3f1c8051 user: drh tags: tkt-e63cbcfd
17:47

16:37

2019-05-04
20:04
Optimize some cases of restarting an RBU vacuum. check-in: cdc09867 user: dan tags: rbu-opt
17:32
