marko	d1f9c8ecea	branches/zip: Minor fixes to get a page with one record compress/decompress. A page with multiple records or deleted records still does not compress or decompress properly. buf_flush_init_for_writing(): Initialize block->page_zip properly so that all assertions in page0zip can be enabled. page_zip_decompress(): Note that corrupt data should not lead to assertions. page_zip_dir_set(): Correct the interface. Fix off-by-one error. page_zip_dir_get(): Fix off-by-one error. page0zip.c: Replace n_heap with n_dense and add comments about the infimum and supremum records whenever we subtract 2 from heap_no. Fix some programming errors.	20 years ago
marko	13002bdffc	branches/zip: Minor fixes. Compression/decompression still fails. buf0flu.c: Allocate the temporary buffer from buf_frame_alloc(). page_zip_simple_validate(): Do not assert page_zip->m_start >= PAGE_DATA. page_zip_compress(): Replace some assertions with page_zip_simple_validate(), and do not assert anything about page_zip->data contents. page_zip_validate(): Do not compare the page trailer bytes. page_zip_write(): Assert that the entire page headers match and that page_zip->m_start >= PAGE_DATA.	20 years ago
marko	48a1ffa5f4	branches/zip: Implement a more compact page format. Add a hook to buf0flu.c for testing compression and decompression. TODO: adapt page_zip_write() calls.	20 years ago

marko	b0b4936341	branches/zip: Minor improvements. page_dir_slot_set_n_owned(): Check page_zip_available(). page_dir_add_slots(): Add parameter page_zip. btr_attach_half_pages(): Add parameter page_zip. btr_node_ptr_set_child_page_no(): Add parameter page_zip.

marko	d8f576e734	branches/zip: Minor improvements. page_set_max_trx_id(), page_update_max_trx_id(): Add parameter page_zip. Check that page_zip_decompress() is never called after modifying the header or trailer of the compressed page, i.e., that page_zip_decompress() will restore the uncompressed page as it was before the failed operation.	20 years ago
marko	83539afab4	branches/zip: Restore left b-tree splits. page_move_rec_list_start(): Restored. Reorganize old page if compressed. btr_page_split_and_insert(): Do left page splits.	20 years ago
