| 22:23 | Merge with the latest CVS changes. No synced with version 3.5.2. Leaf check-in: 6a1be9c926 user: drh tags: trunk | |
| 13:03 | Update to CVS version 4533. check-in: 4b7ef9d972 user: drh tags: trunk | |
|
2007-11-01
| ||
| 14:57 | Added a working "Heap" memory allocator. Works in the sense that it does not segfault when used in place of Linear. Might have other problems, though. check-in: e1ae0cc591 user: drh tags: trunk | |

| 23:48 | Incremental check-in of changes to malloc.c in order to transfer code to a different machine. This version does not compile. check-in: a64c689447 user: drh tags: trunk | |
| 17:51 | Merge in CVS changes through check-in 4518. check-in: 5a4a1af4cb user: drh tags: trunk | |
| 17:48 | Sync against CVS version 4518. check-in: 6e7d26c3bf user: drh tags: trunk | |
| 10:32 | Fix a memory leak that could occur after malloc() failure in main.c. Change some test instrumentation code in printf.c to work with memory pools. check-in: 75c81155c2 user: dan tags: trunk | |
| 09:46 | Fix some asserts in vdbeapi.c that are no longer correct. check-in: a421fc2b95 user: dan tags: trunk | |
| 09:15 | Fix an error in the previous commit. check-in: 1e8386b620 user: dan tags: trunk | |
| 08:47 | Modify MemContext pointers when moving arrays of Mem objects between vdbes in sqlite3VdbeSwap(). check-in: fe49b8e5ca user: dan tags: trunk | |
| 07:50 | When transfering bindings between two statements, make sure the MemContext pointers always point to the vdbe that owns the sqlite3_value structure. check-in: cb1b0bc4e9 user: dan tags: trunk | |
| 07:26 | Change the db-pool allocator so that it always returns NULL when the sqlite3.mallocFailed flag is set. This matches the old sqlite3DbMalloc() behaviour. check-in: d73e0834ab user: dan tags: trunk | |
| 02:39 | Combine the sqlite3* pointer and MPool* pointer on each Mem into a single pointer to a structure (MemContext) holding these values in the sqlite3_stmt object. This saves 4 bytes on each Mem object. check-in: a784fd82ca user: drh tags: trunk | |
| 01:02 | Do more sqlite3_stmt allocations using the P3Pool memory pool. check-in: 03b1433b26 user: drh tags: trunk | |
|

| 19:48 | Passes all tests on mem1 and mem3. Mem2 still segfaults. check-in: 19078b5855 user: drh tags: trunk | |
| 19:25 | The quick.test runs to completion with no segfaults. A single error is reported. check-in: cd525b6b8a user: drh tags: trunk | |
| 19:05 | More tests pass. Still seeing segfaults. check-in: 494d080f5e user: drh tags: trunk | |
| 17:39 | Runs a few tests successfully. check-in: 07fe8ef6e5 user: drh tags: trunk | |
| 16:19 | Compiles but quickly segfaults on a test. check-in: 34c6d325f9 user: drh tags: trunk | |
| 15:38 | Another incremental checkin. Still does not compile, but getting closer. check-in: 3bd23bbac9 user: drh tags: trunk | |
| 15:26 | First pass at installing the MPool functionality. Have not even attempt to compile it yet. This is just an incremental check-in. check-in: 6f51909596 user: drh tags: trunk | |
| 13:06 | Updates to the malloc.c file to add new interfaces. Add for memory pools to sqlite3 and Parse structures in sqliteInt.h. check-in: 7157de426f user: drh tags: trunk | |
|
2007-10-27
| ||
| 18:30 | Add the sqlite3MemsysFree() and sqlite3MemsysIsValid() functions to mem*.c. Changed names of functions to sqlite3MemsysSetTitle() and sqlite3MemsysDump() in accordance with Memory Allocation spec. check-in: 661fddc629 user: drh tags: trunk | |
|
2007-10-26
| ||
| 02:16 | Changes mem3.c again so that the lower order bits of the two previous 32-bit words are always set. Thus an allocation can never be preceded by a valid pointer. check-in: 90fe6e26c3 user: drh tags: trunk | |
| 01:45 | Modify the header format of mem3.c. A checked-out block is signified by a low-order bit in the previous 32-bit word. check-in: 69f123a4de user: drh tags: trunk | |
|
2007-10-25
| ||
| 20:05 | Many changes toward adding memory pools. But now I want to back up and go in a slightly different direction. This check-in saves the state of the changes in case I decide to return to this branch later. Leaf check-in: 85dd7c694c user: drh tags: trunk | |
|
2007-10-24
| ||
| 21:15 | Work-in-progress check-in to facility file transfer between computers. check-in: 8195179a69 user: drh tags: trunk | |
|

| 23:19 | More use of memory pools for P3 values. check-in: 45195d4856 user: drh tags: trunk | |
| 17:38 | Making more use of memory pools for P3 values. This is an incremental check-in. There is much more work to do. check-in: 6bb0e4e899 user: drh tags: trunk | |
| 17:00 | Merge with the CVS 4509 changes of [acb1141f45]. check-in: 40bb1be9ce user: drh tags: trunk | |
| 16:58 | Sync against CVS version 4509. check-in: acb1141f45 user: drh tags: trunk | |
| 02:01 | Add an mprintf implementation for memory pools. check-in: 4dec2b3c79 user: drh tags: trunk | |
| 01:02 | Begin adding a memory pool allocator. Infrastructure is coming into place. Very little is currently allocated using memory pools, though. check-in: 63e9efb4f7 user: drh tags: trunk | |
|
2007-10-22
| ||
| 13:01 | Added the mpool-notes.txt file. No code changes. check-in: f97f91087e user: drh tags: trunk | |
| 12:59 | Comment changes in vdbe.c to describe a hypothetical 3-address machine implementation. No code changes. Current thinking is that this will be a dead-end branch. Leaf check-in: b541bdc3ab user: drh tags: trunk | |
|
2007-10-20

| 21:10 | Sync the substr() changes of CVS check-in 4499. check-in: b6edbefcb1 user: drh tags: trunk | |
| 20:56 | Sync against CVS version 4498. check-in: 3e9e53d7dc user: drh tags: trunk | |

2007-10-19
| ||
| 17:23 | More bug fixes with mem3.c. check-in: 395ef1b6a0 user: drh tags: trunk | |
| 16:57 | Added distinct small chunk and large chunk reuse changes. Other cleanup. check-in: 22ebbb863c user: drh tags: trunk | |
| 13:33 | Enhancements to the sqlite3_memdebug_dump() interface. check-in: 1f984e689a user: drh tags: trunk | |
|
2007-10-18

| 01:57 | Bug fix. We are not about 7% faster than system malloc on speed1.test. check-in: 3191e73faf user: drh tags: trunk | |
| 01:48 | Go back to a simpler allocator. Working somewhat but still shows bugs. check-in: 17965240d1 user: drh tags: trunk | |

| 22:34 | Print out a memory dump when we run out of memory. check-in: 36a1645a6a user: drh tags: trunk | |
| 20:35 | Memory allocation algorithm using best fit. check-in: 6eca36b93c user: drh tags: trunk | |
| 15:20 | Attempt to graft in dlmalloc and use it for memory allocation. Does not work. Strange internal errors within dlmalloc. Leaf check-in: 5f75303060 user: drh tags: trunk | |
| 13:47 | A new memory allocation strategy. This one is fast, but it fragments badly. check-in: 032e6826d4 user: drh tags: trunk | |
| 03:05 | Enhanced algorithm for mem3.c. Hopefully faster. check-in: b0f4f26281 user: drh tags: trunk | |

| 21:38 | Fix byte count tracking in mem3.c. check-in: d669c03544 user: drh tags: trunk | |
