marko fb8ce59909 branches/zip: Assert that only leaf pages of clustered indexes may contain ... externally stored columns. Make some use of the fact in compression and decompression. rec_init_offsets(): Add ut_ad(dict_index_is_clust(index)) before flagging external columns. page_zip_get_trailer_len(): Assert ut_ad(!page_zip->n_blobs) unless dict_index_is_clust(index). page_zip_get_n_prev_extern(): Add ut_ad(dict_index_is_clust(index)). page_zip_compress(), page_zip_decompress_low(): Add dict_index_is_clust() assertions. Allow completely external storage of columns. Simplify the computation of "externs". page_zip_write_rec(): Store leaf node records of non-clustered indexes with one memcpy(), avoiding rec_offs_n_extern() and the for loop. page_zip_write_blob_ptr(): Add ut_ad(dict_index_is_clust(index)). Simplify the computation of "externs". page_zip_clear_rec(): Only attempt to zero out BLOB pointers when the record belongs to a leaf page of a clustered index. page_zip_dir_delete(): Take a fast path when the record is not on a leaf page of a clustered index. Simplify the computation of "externs". page_zip_copy(): Assert that n_blobs is zero on anything else than leaf pages of clustered indexes.		2006-08-21 10:27:15 +00:00
