This code was not able to detect anomalies such as came up as a result of ticket [e4a18565a36884b00edf66541f38c693827968ab] so it is put into a branch for historical reference, with the intent of leaving it out of trunk. file: [759c9aff] check-in: [68b23c3d] user: drh branch: collseq-checking, size: 17132 | |

2009-05-11
| ||
| 20:53 | Rework the logic that generates a schema for tables created using "CREATE TABLE ... AS SELECT ...". Instead of trying to copy the raw datatype string from the right-hand side, just make the type one of TEXT, INT, REAL, NUM, or nothing. This is much simpler than trying to parse and quote datatype strings. Other minor implifications to build.c are bundled with this change. (CVS 6626) file: [bf295cfd] check-in: [33cf8359] user: drh branch: trunk, size: 14978 | |

|
2008-09-09
| ||
| 12:31 | Calling sqlite3_create_function with nArg==(-1) does not override prior calls on the same function name with nArg>=0. Ticket #3345. Add the new -argcount option to the "function" method in the TCL interface. (CVS 5684) file: [7a40fd44] check-in: [5aa5b804] user: drh branch: trunk, size: 14833 | |
|
2008-09-01

|
2008-08-20
| ||
| 14:49 | Add the pcache module from the experimental branch. Also change things so that most of the built-in SQL functions are kept in single static hash-table, rather than creating and populating a separate hash table for each open database connection. (CVS 5566) file: [1b1a5c58] check-in: [cb494e10] user: danielk1977 branch: trunk, size: 13411 | |
|
2008-07-28
| ||

|
2007-08-21
| ||
| 19:33 | The sqlite3_value object now carries an sqlite3* pointer to use for recording malloc failures. This eliminates the need to pass sqlite3* pointers into many internal interfaces. Also added more mutexing. (CVS 4263) file: [fdd52737] check-in: [92872761] user: drh branch: trunk, size: 12574 | |

|
2007-02-02
