| 14:19 | Fix a problem with the incremental blob API. sqlite3_blob_open() was always reading the data for the leftmost column of the row that the opened blob was stored in. If this column happened to contain a (the) large blob, sqlite would make a large memory allocation to read the data into. Which defeats the purpose of using incremental blobs.

| 02:51 | Continuing work on the new memory allocation subsystem. Added routines for temporary memory allocation. Right the btree balance mechanism to only do one temporary allocation at a time. (CVS 5220) check-in: 65fe7b62 user: drh tags: trunk | |
