The insert buffer only covers operations on leaf pages of secondary indexes. For pages covered by the insert buffer, limit the max_ins_size to page_zip_max_ins_size(). buf_page_get_gen(): Merge the insert buffer after decompressing the page. buf_page_io_complete(): Relax the assertion about ibuf_count. For compressed-only pages, the insert buffer merge takes place in buf_page_get_gen(). ibuf_index_page_calc_free_bits(), ibuf_index_page_calc_free_from_bits(), ibuf_index_page_calc_free(), ibuf_update_free_bits_if_full(), ibuf_update_free_bits_low(), ibuf_update_free_bits_for_two_pages_low(), ibuf_set_free_bits_low(): Add the parameter zip_size.

marko	ebeee34510	btr_store_big_rec_extern_fields(): Write the (space_id, page_no) of the record on every compressed BLOB page header, so that compressed BLOBs can be relocated or the chain of BLOB pages can be validated.	19 years ago
marko	e3893c65df	branches/zip: Correct a bug introduced in r1014: Always assign node->block when assigning node->data. ha_delete(), ha_search_and_delete_if_found(), ha_remove_all_nodes_to_page(): Remove the parameter buf_block_t* block, now that it is stored within the hash data structure in debug builds.	19 years ago
marko	d25fa2c4d9	branches/zip: Remove the buf_block_align() calls from ha0ha.c that caused an assertion failure in debug builds when a context switch occurred in buf_LRU_search_and_free_block() before the call to btr_search_drop_page_hash_index() managed to acquire the mutexes again. ha_node_t: Add the field buf_block_t* block. ha_search_and_update_if_found(): Rename to ha_search_and_update_if_found_func() with added buf_block_t* parameter in debug builds.

marko	fc86d41650	branches/zip: buf_block_align(): Remove from non-debug builds. btr_search_guess_on_hash(), btr_search_validate(): Instead of buf_block_align(), call buf_page_hash_get(), and allow it to return NULL.	19 years ago
marko	ce15bd43f0	branches/zip: ha_delete_hash_node(): Do not call buf_block_align(). Instead, get buf_block_t* as a parameter. Without this patch, buf_page_hash_get() would return NULL in buf_block_align(). The function buf_LRU_search_and_free_block() invokes buf_LRU_block_remove_hashed_page(), which removes the hash mapping needed by buf_page_hash_get().	19 years ago
marko	694f267391	branches/zip: Always call buf_block_align() while holding buf_pool->mutex. This was forgotten from r977.	19 years ago

marko	a3d72680f6	branches/zip: Add const qualifiers to read-only pointers. rec_get_nth_field_offs_old(): Split from rec_get_nth_field_old(). rec_get_nth_field_old(): Reimplement as a constness-preserving macro. dict_drop_index_tree(), dict_truncate_index_tree(): Note that rec is an in/out parameter, as the B-tree root page number will be updated.	19 years ago
marko	dfb8add7b3	branches/zip: btr_store_big_rec_extern_fields(): Replace page_get_page_no(page_align(field_ref)) calls with a local variable rec_page_no = buf_block_get_page_no(rec_block).	19 years ago

marko	9ac3df7687	branches/zip: Remove a few buf_block_align() calls from debug builds. btr_check_node_ptr(): Replace page_t* parameter with buf_block_t*. btr_free_externally_stored_field(): Add const qualifier to rec. Remove an explicit buf_block_align() call, but replace an mtr_memo_contains() with mtr_memo_contains_page(). row_upd_rec_sys_fields(): Reorder an assertion containing buf_block_align() so that the costly call can be avoided in some cases.	19 years ago
marko	42dcad50b8	branches/zip: Remove all references to buf_block_align() except those from the adaptive hash index [btr_search_guess_on_hash() and btr_search_validate()]. Some references to buf_block_align() remain in debug builds. btr_store_big_rec_extern_fields(): Add the parameter rec_block. page_rec_get_next_low(): Do not assume that the page has been allocated from the buffer pool when printing the diagnostic information. page_cur_insert_rec_low(): Replace the parameter page_zip_des_t* page_zip with the parameter buf_block_t* block.	19 years ago
marko	9b0a89867e	branches/zip: Remove all buf_block_align() calls from lock0lock.c. Replace all page_t* parameters with buf_block_t, and replace many rec_t parameters with heap_no. This eliminates also many rec_get_heap_no() calls, which became more expensive with the introduction of ROW_FORMAT=COMPACT in MySQL/InnoDB 5.0.3. page_rec_get_heap_no(), lock_get_min_heap_no(): New functions.	19 years ago
marko	7e8c129370	branches/zip: buf_page_get_release_on_io(), buf_page_get_gen(): Replace buf_frame_t* guess with buf_block_t* guess in order to avoid a buf_block_align() call. trx_undo_t: Replace page_t* guess_page with buf_block_t* guess_block. btr_search_t: Replace page_t* root_guess with buf_block_t* root_guess.	19 years ago
marko	009533b471	branches/zip: Minor cleanup. page_set_max_trx_id(): Replace page_t* parameter with buf_block_t*, to avoid a buf_block_align() call. Replace some occurrences of page_get_page_no() with buf_block_get_page_no(). page_cur_delete_rec(): Replace buf_block_align() with page_cur_get_block().	19 years ago
marko	f97f00ee60	branches/zip: Fix some bugs. btr_cur_pessimistic_insert(): Remove local variable "block". Replace an extraneous call to btr_cur_position() [with wrong "block", in r948] with a debug assertion that the cursor is positioned on the preceding record after the page split. btr_pcur_restore_position(): Do not use btr_pcur_get_page(), because the debug assertion there could fail. This bug was introduced in r928.	19 years ago
marko	8e33825034	branches/zip: btr_search_drop_page_hash_index(): Do not call buf_block_get_frame(), because it will lead to debug assertion failure when buf_fix_count == 0. This bug was introduced in r908.	19 years ago
marko	8562e752bc	branches/zip: Remove some more buf_block_align() calls. btr_cur_t: Move page_block to page_cur_t::block. page_cur_get_block(), page_cur_get_page_zip(): New functions. page_cur_position(): Add parameter block. Remove many page_zip parameters, now that there is page_cur_get_page_zip(). Replace some page, page_zip parameters with block. Add some const qualifiers to function parameters and remove casts. PAGE_HEAP_NO_INFIMUM, PAGE_HEAP_NO_SUPREMUM, PAGE_HEAP_NO_USER_LOW: New constants. Replace some cursor code in low-level diagnostic functions with direct management of rec, because buf_block_t::buf_fix_count may be 0 when the functions are called, and debug assertions would fail.	19 years ago
marko	3e1c60b96f	branches/zip: btr_search_guess_on_hash(): Do not call buf_block_get_frame(), because it will lead to debug assertion failure when buf_fix_count == 0. This bug was introduced in r912.	19 years ago
