| 18:18 | Defer the bulk pcache1 memory allocation until the first page allocation request. Limit the size of the pcache1 bulk allocation to the cache_size setting. Deallocate the bulk allocation on a sqlite3_db_release_memory() request, if the bulk allocation is completely unused. check-in: b79a4aff user: drh tags: trunk | |
