| 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: 8d2a062eb8 user: dan tags: trunk) | |
| 18:13 | Make the ".schema" command in the CLI resistant to corrupt database files. (check-in: f22c7e229e 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: 3eae4e301e 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: 9b0915272f 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: 20f06bf2e6 user: dan tags: trunk) | |
| 16:22 | Improved debugging output from the OP_MakeRecord opcode. (check-in: ac790729d9 user: drh tags: trunk) | |
| 15:51 | Fix another corruption related buffer overread in the sqlite_dbdata module. (check-in: 5cd728fb6b user: dan tags: trunk) | |
| 15:07 | Fix further buffer overreads triggered by passing corrupt records to the sqlite_dbdata module. (check-in: dbc6a9f7f6 user: dan tags: trunk) | |
| 14:15 | Have ".recover" handle cases where the sqlite_master table contains malformed SQL statements. (check-in: e736da9c18 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: 47fa65343e 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: d99bb0c11d user: dan tags: trunk) | |
| 11:21 | Merge accidental fork in trunk. (check-in: ec9373031d 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: 7ccf2e7d41 user: dan tags: trunk) | |
| 11:18 | Improved error handling for the ".open --hexdb" command of the CLI. (check-in: 4fa831d5cd user: drh tags: trunk) | |

| 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: ebe4845cd0 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: 51d32173ff user: drh tags: trunk) | |
| 21:14 | Add another test case to cover a previously uncovered branch in the RBU module. (check-in: 3039298561 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: 740201107a user: drh tags: trunk) | |
| 19:32 | Simplification to the logic underlying PRAGMA case_sensitive_like. (check-in: ef0015fde4 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: 8658574e3f user: drh tags: trunk) | |
| 18:49 | Add tests to improve code coverage of the RBU module. (check-in: ecb56b75a0 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: eabe7f2d4f 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: 658b84d7f4 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: a870c196d7 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: ad8fc5d8b4 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: 74eba2558a 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: a0819086a5 user: drh tags: trunk) | |
|

| 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: 3c75605b46 user: drh tags: trunk) | |
| 19:44 | Do not commit an "OR FAIL" statement that causes foriegn key constraint violations. (check-in: 659c551dcc user: dan tags: trunk) | |
| 19:21 | Add test cases for the fix on this branch. (Closed-Leaf check-in: 2e31abe0ae 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: 3f1c805164 user: drh tags: tkt-e63cbcfd) | |
| 17:47 | Strive to prevent harmless compiler warnings in GCC 4.8.5. (check-in: 8b6691f619 user: drh tags: trunk) | |
| 16:37 | Optimize the restarting of an RBU vacuum. (check-in: 82062351a6 user: dan tags: trunk) | |
| 16:28 | Remove some redundant code from sqlite3rbu.c. Add test cases for RBU vacuum. (Closed-Leaf check-in: 7b051698d8 user: dan tags: rbu-opt) | |
| 02:57 | Add the exprNodeCopy() routine that will safely memcpy() an Expr node that might be a size-reduced node. (Leaf check-in: ab2ba8e732 user: drh tags: expr-node-copy-patch) | |
|

| 20:40 | Optimize further cases of restarting an RBU vacuum. (check-in: 6b3261bfa1 user: dan tags: rbu-opt) | |
| 16:15 | Fix a problem with renaming an INTEGER PRIMARY KEY column of a WITHOUT ROWID table using ALTER TABLE. (check-in: 91f701d398 user: dan tags: trunk) | |
|
2019-05-04
| ||
| 20:04 | Optimize some cases of restarting an RBU vacuum. (check-in: cdc09867ed user: dan tags: rbu-opt) | |
| 17:32 | Fix the NOT NULL logic in the theorem prover that determines when a partial index can be used. Ticket [5c6955204c392ae763a95]. (check-in: c2e439bccc user: drh tags: trunk) | |
| 03:56 | Fix harmless compiler warning seen with MSVC. (check-in: 5862b83eb3 user: mistachkin tags: trunk) | |
| 01:41 | In the sqlite3_value or Mem object, make the MEM_IntReal type completely independent from MEM_Int and MEM_Real. This helps avoid problems when inserting non-float values into a "REAL" column. (check-in: 5a8a23ee5f user: drh tags: trunk) | |
| 01:29 | New testcase macros to ensure that MEM_IntReal is fully tested. (Closed-Leaf check-in: 8b8ef445cc user: drh tags: int-real) | |
|
2019-05-03
| ||
| 21:17 | Add the SQLITE_TESTCTRL_RESULT_INTREAL test-control and use it to create the intreal() SQL function in testfixture. Write a few simple tests to prove this all works. TH3 will hold most of the INTREAL tests, probably. (check-in: c983873132 user: drh tags: int-real) | |
| 19:34 | Ensure that UTF16 strings are properly zero-terminated before returning them in an sqlite3_value_text16() request, even if the string is invalid UTF16 because it was formed from an arbitrary and/or odd-length BLOB. (check-in: 3a16ddf91f user: drh tags: trunk) | |
| 18:50 | Fix a memory-leak/segfault caused by using OP_OpenDup and OP_OpenEphemeral on the same VM cursor. (check-in: a9b90aa12e user: dan tags: trunk) | |
| 17:19 | Fix a problem where self-joins on views that are aggregate queries may return the wrong result. (check-in: 74ef97bf51 user: dan tags: trunk) | |
| 17:08 | Improved comments on the elements of the array constant used to implement the sqlite3_value_type() interface. (check-in: f73a7de7a5 user: drh tags: int-real) | |
| 02:41 | Fix the ".open --hexdb" command in the CLI so that it works even with terminal input. (check-in: 9b5d943426 user: drh tags: trunk) | |
|
2019-05-02
| ||
| 21:36 | Make MEM_IntReal a completely independent type, meaning a floating point value stored as an integer. This fixes a problem with arithmetic within arguments to string functions on indexes of expressions. But it is a big change and needs lots of new testcase() macros for MC/DC and so it is initially put on this branch. (check-in: dba836e31c user: drh tags: int-real) | |
| 17:45 | Ensure that the typeof() function always returns SQLITE_FLOAT for floating point values even when the value is stored as an integer to save space. (check-in: 48889530a9 user: drh tags: trunk) | |
