branches/zip: In r988, the function buf_block_align() was enclosed
within UNIV_DEBUG. The two remaining callers in non-debug builds,
btr_search_guess_on_hash() and btr_search_validate(), were rewritten
to call buf_page_hash_get().
To implement support for a resizeable buffer pool, the function
buf_block_align() had been rewritten to perform a page hash lookup in
the buffer pool. The caller was also made responsible for holding the
buffer pool mutex.
Because the page hash lookup is expensive and it has to be done while
holding the buffer pool mutex, implement buf_block_align() by pointer
arithmetics again, and make btr_search_guess_on_hash() call it. Note
that this will have to be adjusted if the interface to the resizeable
buffer pool is actually implemented.
rb://83 approved by Heikki Tuuri, to address Issue #161.
As a deviation from the approved patch, this patch also makes
btr_search_validate() (invoked by CHECK TABLE) check that
buf_pool->page_hash is consistent with buf_block_align().

message:
Bug#31177: Server variables can't be set to their current values
Bounds-checks and blocksize corrections were applied to user-input,
but constants in the server were trusted implicitly. If these values
did not actually meet the requirements, the user could not set change
a variable, then set it back to the (wonky) factory default or maximum
by explicitly specifying it (SET <var>=<value> vs SET <var>=DEFAULT).
Now checks also apply to the server's presets. Wonky values and maxima
get corrected at startup. Consequently all non-offsetted values the user
sees are valid, and users can set the variable to that exact value if
they so desire.

buf_flush_try_page(): Rename to buf_flush_page(), and change the
return type to void. Replace the parameters space, offset with bpage,
and remove the second page hash lookup. Note and assert that both
buf_pool_mutex and block_mutex must now be held upon entering the
function. They will still be released by this function.
buf_flush_try_neighbors(): Replace buf_flush_try_page() with
buf_flush_page(). Make the logic easier to follow by not negating the
precondition of buf_flush_page().

ut_ad() or nothing.
dict_table_add_to_columns(): Assert that the table being added to the data
dictionary cache is not already being pointed to by the name_hash and
id_hash tables.
HASH_SEARCH_ALL(): New macro, for use in dict_table_add_to_columns().
dict_mem_table_free(): Set ut_d(table->cached = FALSE), so that we can
check ut_ad(table->cached) when traversing the hash tables, as in

branches/5.1: Fix Bug#38187 Error 153 when creating savepoints
InnoDB previously treated savepoints as a stack e.g.,
SAVEPOINT a;
SAVEPOINT b;
SAVEPOINT c;
SAVEPOINT b; <- This would delete b and c.
This fix changes the behavior to:
SAVEPOINT a;
SAVEPOINT b;
SAVEPOINT c;
SAVEPOINT b; <- Does not delete savepoint c

------------------------------------------------------------------------
buf_pool->mutex: Rename to buf_pool_mutex, so that the wrappers will have
to be used when changes are merged from other source trees.
buf_pool->zip_mutex: Rename to buf_pool_zip_mutex.
buf_pool_mutex_own(), buf_pool_mutex_enter(), buf_pool_mutex_exit():
Wrappers for buf_pool_mutex.
buf_page_get_release_on_io(): Removed this unused function.
ibuf_build_entry_from_ibuf_rec(): Justify why it is not necessary to
add system columns to the dummy table pointed to by the dummy secondary index.
page_zip_rec_set_deleted(): Add a page_zip_validate() assertion.
buf_LRU_free_block(): Check that the block descriptor contains valid data.
buf_buddy_relocate(): Check that the source block contains valid data.
buf_page_get_gen(): Do not dereference bpage after calling buf_relocate().
This avoids a bogus Valgrind warning; the memory itself was valid.
buf_page_hash_get(): Check that the returned block descriptor contains
valid data.
page_cur_set_before_first(), page_cur_set_after_last(),
page_cur_position(): Add const qualifiers to buf_block_t and rec.
A better solution would be to define a const_page_cur_t and a
set of accessors, but it would lead to severe code duplication.
page_rec_get_n_recs_before(): Add const qualifiers.
page_dir_get_nth_slot(): Define as a const-preserving macro.
page_dir_slot_get_rec(), page_dir_slot_get_n_owned(),
page_dir_find_owner_slot(), page_check_dir(): Add const qualifiers.
page_rec_get_next_low(): Add const qualifiers.
page_rec_get_next_const(), page_rec_get_prev_const(): New functions,
based on the const-less page_rec_get_next() and page_rec_get_prev().
page_cur_get_page(), page_cur_get_block(), page_cur_get_page_zip(),
page_cur_get_rec(): Define as const-preserving macros.
page_cur_try_search_shortcut(), page_cur_search_with_match():
Add const qualifiers.
buf_page_get_mutex(): Add a const qualifier to buf_page_t*.
rec_get_next_ptr_const(): Const variant of rec_get_next_ptr().
For some reason, GCC 4.2.1 ignores casts (for removing constness)
in calls to inline functions.
page_align(), ut_align_down(): Make the parameter const void*, but still
return a non-const pointer. This is ugly, but these functions cannot be
replaced with a const-preserving macro in a portable way, given that
the pointer argument is not always pointing to bytes.
buf_block_get_page_zip(): Implement as a const-preserving macro.
buf_frame_get_page_zip(), buf_block_align(): Add const qualifiers.
lock_rec_get_prev(): Silence GCC 4.2.1 warnings.
mlog_write_initial_log_record(), mlog_write_initial_log_record_fast(),
mtr_memo_contains(): Add const qualifier to the pointer.
page_header_get_ptr(): Rewrite as page_header_get_offs(), and
implement as a macro that calls this function.
buf_block_hash_get(): New function, similar to buf_page_hash_get().
buf_page_get_block(): Remove the const qualifiers. This is a low-level
function, and the operations on block->mutex are non-const.
buf_page_try_get_func(): Implement with lower-level predicates, somewhat
similar to buf_page_get_known_nowait().
lock_rec_print(): Remove the unused variable zip_size and the
call to fil_space_get_zip_size(). Adapt to buf_page_try_get() returning
a const pointer.
only after the buffer_cache has warmed up. During the initial warmup
phase these values are set to zero. We should recommend to move the
block to the start of the LRU in this case.
Also added some comments to buf0buf.c about the LRU logic.
reviewed by: Sunny
C++ requires explicit type casts when converting from void*, and *.ic files
are now inlined in ha_innodb.cc.
fil_space_get_by_id(), fil_space_get_by_name(): New inline functions, to
replace occurrences of the HASH_SEARCH() macro in fil0fil.c. This should
improve readability.
uncompressed page frames.
buf_page_get_zip(), buf_page_release_zip(): New functions, used
by btr_copy_zblob_prefix().
btr_copy_zblob_prefix(): Do not call inflateEnd().
buf_page_get_gen(). This saves one mutex operation per block request.
buf_page_get_gen(), various macros and functions: Add parameter zip_size.
btr_node_ptr_get_child(): Add parameter index.
fil_space_get_latch(): Add optional output parameter zip_size.
fil_space_get_zip_size(): Return 0 for space id==0, because the
system tablespace is never compressed.
fsp_header_init(): Remove the parameter zip_size.
ibuf_free_excess_pages(): Remove the parameter zip_size.
trx_rseg_t, trx_undo_t: Add field zip_size.
xdes_lst_get_next(): Remove, unused.
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.
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.
buf_LRU_get_free_block(): Document that the block is in the state
BUF_BLOCK_READY_FOR_USE.
buf_block_alloc(): Change the state of the block to BUF_BLOCK_MEMORY
and document it.
Replace those invocations of buf_block_alloc() with
buf_LRU_get_free_block() where the allocated block is used for buffer
pool input and output. However, temporary copies of B-tree pages
during reorganization are not used for file I/O, and such blocks are
still allocated with buf_block_alloc().
compressed pages from the buffer pool.
Makefile.am: Add buf0buddy.h, buf0buddy.ic.
buf/Makefile.am: Add buf0buddy.c.
Introduce the constants BUF_BUDDY_LOW and BUF_BUDDY_SIZES.
buf_pool_t: Add zip_mutex and the lists zip_clean and zip_free[].
buf_page_get_mutex(): Return &buf_pool->zip_mutex instead of NULL.
buf_buddy_get_offset(), buf_buddy_get(), buf_buddy_get_slot(),
buf_buddy_alloc_free(), buf_buddy_alloc_free_low(): New functions.

and buf_page_get_mutex().
buf_block_get_newest_modification(): Rename to
buf_page_get_newest_modification().
LRU_position and possibly freed_page_clock. All these fields are
protected by buf_pool->mutex rather than buf_page_get_mutex().
buf_page_set_accessed(): Add a mutex_own() assertion.
decompression from page_zip_des_t to buf_page_t, because the fields
needed in compression are modified without holding the block mutex.
All writes to bit-fields sharing a machine word must be protected
by the same mutex or rw-lock.
buf_block_t. Move the fields "hash" and "file_page_was_freed" from
buf_block_t to buf_page_t.
buf_page_in_file(): New function, for checking block state in assertions.
storage size from 16 to 3 bits.
page_zip_get_size(), page_zip_set_size(): New functions.
Replace direct references to page_zip_des_t:size with calls to
buf_block_get_zip_size(), page_zip_get_size(), and page_zip_set_size().

buf_block_t: Replace page_zip, space, and offset with buf_page_t page.
Replace some integers with bit-fields.
enum buf_block_state: Rename to buf_page_state. Add BUF_BLOCK_ZIP_PAGE.
page_zip_des_t: Add the field "state". Make the integer fields bit-fields.
page_zip_copy(): Document which fields are copied.
buf_block_get_space(), buf_block_get_page_no():
Remove ut_ad(block->buf_fix_count > 0), because since r1052
these functions are also used in low-level code.
