marko	bddb5a0cca	branches/zip: Add a UNIV_INTERN qualifier to every global function declaration in .h files, so that the function signatures in the .h and *.c files fully match each other. ut_dulint_sort(): Add a UNIV_INTERN qualifier also to the function definition.	18 years ago
marko	e77a82a054	branches/zip: buf_flush_write_block_low(): Avoid recomputing the compressed page checksum of compressed-only blocks. Pass the compressed page frame to fil_io() when needed. page_zip_calc_checksum(): Skip also FIL_PAGE_LSN and FIL_PAGE_FILE_FLUSH_LSN. buf_flush_init_for_writing(): Expect page to be non-NULL.	19 years ago
marko	a85fd29415	branches/zip: Allow dirty compressed-only blocks to exist in the buffer pool and to be flushed to disk. buf_LRU_free_block(): Enable the freeing of uncompressed pages of compressed tablespaces. trx_doublewrite->buf_block_arr[]: Change the type from buf_block_t* to buf_page_t. buf_flush_ready_for_flush(): Add debug assertion. buf_flush_buffered_writes(), buf_flush_try_page(): Support blocks of type BUF_BLOCK_ZIP_DIRTY. buf_flush_post_to_doublewrite_buf(), buf_flush_write_block_low(): Change the type of the parameter from buf_block_t to buf_page_t*. buf_flush_init_for_writing(): Allow page to be NULL if page_zip_ is non-NULL.	19 years ago
marko	91c87cd343	branches/zip: Allow dirty blocks to be relocated. Allow a transition to BUF_BLOCK_ZIP_DIRTY (discarding the uncompressed page corresponding to a modified compressed page that has not been flushed to disk). buf_page_can_relocate(): New function, modelled after buf_flush_ready_for_replace(). buf_LRU_free_block(): Allow the transition to BUF_BLOCK_ZIP_DIRTY. buf_flush_insert_into_flush_list(): Make the prototype public. buf_buddy_relocate(): Remove an unnecessary switch statement. Use buf_page_can_relocate() instead of buf_flush_ready_for_replace(). buf_page_peek(): Made UNIV_INLINE. Document UNIV_ZIP_DEBUG.	19 years ago
marko	0fb620f58d	branches/zip: Minor improvements. buf_flush_remove(): New function, for removing a block from the flush list. Sliced from buf_flush_write_complete(). buf_page_set_state(): Allow transitions between BUF_BLOCK_ZIP_PAGE and BUF_BLOCK_ZIP_DIRTY.	19 years ago
marko	6c0a4186af	branches/zip: Allow some functions to work on compressed-only pages (state == BUF_BLOCK_ZIP_PAGE). Make use of buf_page_in_file() and buf_page_get_mutex(). buf_block_get_newest_modification(): Rename to buf_page_get_newest_modification().	19 years ago
marko	aedce8cde3	branches/zip: Move the fields related to the least-recently-used algorithm of the buffer pool from buf_block_t to buf_page_t. Replace some buf_block_t* parameters with buf_page_t*. Add accessor functions.	19 years ago
marko	329a29c2fb	branches/zip: Replace ib_ulonglong with ib_uint64_t, since we want exactly 64 bits. "long long" might be longer than 64 bits on some systems.	19 years ago
marko	b03460d90d	branches/zip: Move the page flushing fields from buf_block_t to buf_page_t and page_zip_des_t.	19 years ago
marko	7593a465db	branches/zip: Introduce the unsigned 64-bit data type ib_ulonglong for log sequence numbers, to replace dulint.	19 years ago
marko	03bdaaf509	branches/zip: Introduce a new preprocessor symbol, UNIV_BUF_DEBUG, and enclose buf_validate() and friends in it.	19 years ago
marko	2018ce35b3	branches/zip: Implement resizeable buffer pool. mysql.patch: Patch to change or add variables to MySQL innodb.patch: Patch to make the master thread poll requests to resize the buffer pool. Replace srv_pool_size and innobase_buffer_pool_size with srv_buf_pool_size, srv_buf_pool_old_size, and srv_buf_pool_curr_size. Add buf_chunk_t, a collection of buf_block_t.	19 years ago
marko	6241b552aa	branches/zip: Stamp (space_id, page_no) on buffer pool pages early on. buf_flush_init_for_writing(): Remove parameters space, page_no. fsp_init_file_page_low(): Wriet space_id and page_no to the page. fil_create_new_single_table_tablespace(): Write space_id to the page.	19 years ago
marko	7f2d91cba9	branches/zip: Fix some bugs in incremental compression. btr_create(): page_zip_compress() returns FALSE on failure. page_zip_write_header(): Write to page_zip->data[] instead of page_zip[]. buf_flush_init_for_writing(): Add parameter page_zip and set the fields also in the header of the compressed page. btr_cur_search_to_nth_level(): Add ut_ad() on page_zip_validate().	20 years ago
marko	747c8fad44	branches/zip: Merge revisions 200:236 from trunk.	20 years ago
osku	2903c72469	Import 5.0 code.	20 years ago
