2009-03-24

[9345f6dc] part of check-in [1b9478da] 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. (CVS 5222) (check-in: [1b9478da] user: danielk1977 branch: trunk, size: 10732)

2007-08-21
19:33
[d12ed95d] part of check-in [92872761] 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) (check-in: [92872761] user: drh branch: trunk, size: 10074)
15:13
