2009-08-07
| ||
| 16:56 | Enhancement to (6844). If sqlite3_exec() is to return SQLITE_NOMEM because it fails to allocate space for an error message, set the database error-code to SQLITE_NOMEM too. (CVS 6962) file: [303b4ffc] check-in: [8293fa19] user: danielk1977 branch: trunk, size: 4639 | |

|
2008-12-10
| ||

|

|
2008-03-21
| ||
| 18:01 | Defer allocating memory space to hold the array of column values and names in sqlite3_exec() until there is a need to use the array.

2007-08-16
| ||
| 04:30 | Half-way through a major refactoring of the memory allocation. I have not even attempted to compile so I am certain there are countless errors. (CVS 4231) file: [6013a7cb] check-in: [deb7ecd6] user: drh branch: trunk, size: 3711 | |
|
2007-05-04
| ||
| 13:15 | Eliminate all uses of sprintf() and strcpy(). These were not being misused. But getting rid of them removes a library dependency. And it avoids warnings from the OpenBSD compiler. Ticket #2336. (CVS 3916) file: [388c71ad] check-in: [ba4845b3] user: drh branch: trunk, size: 3696 | |

|
2006-09-15
| ||
| 07:28 | Add support for extended result codes - additional result information carried in the higher bits of the integer return codes. This must be enabled using the sqlite3_extended_result_code() API. Only a few extra result codes are currently defined. (CVS 3422) file: [2631df6a] check-in: [ba579ddc] user: drh branch: trunk, size: 3776 | |
|
2006-06-26
| ||
| 21:35 | Publish APIs sqlite3_malloc() and sqlite3_realloc() that use the OS-layer memory allocator. Convert sqlite3_free() and sqlite3_mprintf() to also use the OS-layer memory allocator. (CVS 3298) file: [10e01a90] check-in: [85a66a25] user: drh branch: trunk, size: 3742 | |
|
2006-03-06
| ||
| 20:55 | Code changes resulting from Coverity analysis. http://scan.coverity.com/ Found 1 potential segfault in sqlite3_mprintf(). Also 2 failures to fclose() following a malloc() failure. And lots of cases where unnecessary conditionals could be removed from the code. (CVS 3126) file: [fa15d505] check-in: [e510e6dd] user: drh branch: trunk, size: 3734 | |
|
2006-01-23
| ||

|
2006-01-18
| ||
| 15:25 | Change sqlite3MallocClearFailed() calls to sqlite3ApiExit(), a better API. (CVS 2970) file: [0fd27db5] check-in: [e0b022e5] user: danielk1977 branch: trunk, size: 3746 | |
|
2006-01-11
| ||
| 21:41 | Automatically deallocate thread-specific data when it is no longer being used. Ticket #1601. Also implemented the suggestion of ticket #1603. Memory management is now off by default at compile-time. The sqlite3_enable_memory_management() API has been removed. (CVS 2919) file: [9bf7ee1b] check-in: [5d9c6aa9] user: drh branch: trunk, size: 3819 | |
|
2006-01-09

|
2005-12-06
| ||
| 12:52 | Some elements of the new malloc() failure handling. Not all cases work properly yet. Also, library is not threadsafe if malloc() fails right now. (CVS 2800) file: [7b88d20e] check-in: [e1606658] user: danielk1977 branch: trunk, size: 3803 | |
|

| 17:24 | Fix a naming conflict between sqlite versions 2 and 3. An open sqlite3 connection now *must* be called "sqlite3". You cannot call it "sqlite". This might break existing code. (CVS 1941) file: [1cf9a326] check-in: [3ddf5a9d] user: drh branch: trunk, size: 3790 | |
|
2004-08-08
