branches/zip: ibuf_use_t: Add the constant IBUF_USE_COUNT, to eliminate
a gcc warning about an assertion that trivially holds.
The warning was introduced in r4061, in the merge of
branches/innodb+ -r4053.

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().

branches/zip: btr_search_validate(): Fix a bogus UNIV_DEBUG
assertion failure that was accidentally introduced in r4036.
Instead of calling buf_block_get_frame(), which asserts that the
block must be buffer-fixed, access block->frame directly. That
is safe, because changes of block->page.state are protected by
the buffer pool mutex, which we are holding.
This bug was reported by Michael.

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.

------------------------------------------------------------------------
innodb_change_buffering, with the following values:
none - buffer nothing
inserts - buffer inserts (like InnoDB so far)
deletes - buffer delete-marks
changes - buffer inserts and delete-marks
purges - buffer delete-marks and deletes
all - buffer all operations (insert, delete-mark, delete)
The default is 'all'. All values except 'none' and 'inserts' will make
InnoDB+ write new-format records to the insert buffer, even for inserts.
We will implement this variable in the InnoDB Plugin 1.0.3 with the values
'none' and 'inserts' (the default).
This patch also adds a #if 0 TODO snippet for tagging the insert buffer
format in the system tablespace. This is related to
https://svn.innodb.com/innobase/Saving_last_shutdown_state and Issue #81.

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.
Do not assume anything about the contents of the bitmap.
ibuf_update_free_bits_low(): Use this function only for uncompressed pages.
Remove the parameter zip_size. This function avoids latching the bitmap page
and updating the bitmap when the bits do not change.
ibuf_update_free_bits_zip(): New function based on ibuf_update_free_bits_low(),
for use on compressed pages. Remove the parameter max_insert_size that
was used for computing the before image of the free bits. Always update the
bitmap.
ibuf_index_page_calc_free_zip(): New function, factored out from
ibuf_index_page_calc_free().
ibuf_update_free_bits_if_full(): Document that this function must only be
invoked on uncompressed pages. Add a debug assertion about this.
the insert buffer bitmap.
ibuf_set_free_bits_func(): Never disable redo logging.
ibuf_update_free_bits_zip(): Remove.
btr_page_reorganize_low(), page_zip_reorganize(): Do not update the insert
buffer bitmap. Instead, document that callers will have to take care of it,
and adapt the callers.
btr_compress(): On error, reset the insert buffer free bits.
btr_cur_insert_if_possible(): Do not modify the insert buffer bitmap.
btr_compress(), btr_cur_optimistic_insert(): On compressed pages,
reset the insert buffer bitmap. Document why.
btr_cur_update_alloc_zip(): Document why it is necessary and sufficient
to reset the insert buffer free bits.
btr_cur_update_in_place(), btr_cur_optimistic_update(),
btr_cur_pessimistic_update(): Update the free bits in the same
mini-transaction. Document that the mini-transaction must be
committed before latching any further pages. Verify that this
is the case in all execution paths.
row_ins_sec_index_entry_by_modify(), row_ins_clust_index_entry_by_modify(),
row_undo_mod_clust_low(): Because these functions call
btr_cur_update_in_place(), btr_cur_optimistic_update(), or
btr_cur_pessimistic_update(), document that the mini-transaction must be
committed before latching any further pages. Verify that this is the case
in all execution paths.
crash recovery is in progress. This avoids a hang when
btr_parse_page_reorganize(), called from an I/O handler thread,
attempts to acquire log_sys->mutex while it is being held by
the main thread (the one that runs innobase_init()). This change
was committed accidentally. It may be unsafe to clear
mtr.modifications, because buf_page_release() at mtr_commit() may
forget to put modified pages to the flush list.
Cleanup: Remove the "type" parameter from many ibuf functions.
Let the caller check that !dict_index_is_clust(). This should avoid
function calls and register spilling.
ibuf_set_free_bits_func(), ibuf_set_free_bits(): Remove the parameter "type".
ibuf_reset_free_bits_with_type(): Rename to ibuf_reset_free_bits().
Remove the parameter "type".
ibuf_update_free_bits_if_full(), ibuf_update_free_bits_zip(),
ibuf_update_free_bits_low(), ibuf_update_free_bits_for_two_pages_low():
Remove the parameter "index".
page_zip_max_ins_size(): New function.
btr_cur_optimistic_insert(), btr_cur_optimistic_delete(),
btr_page_split_and_insert(), btr_compress(): Do not update the
ibuf free bits for non-leaf pages or pages belonging to a clustered index.
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. Limit the maximum
insert size to page_zip_max_ins_size().
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.
ibuf_reset_free_bits(): Remove, as there already is a similar function
ibuf_reset_free_bits_with_type().
ibuf_reset_free_bits_with_type(), ibuf_set_free_bits(),
ibuf_update_free_bits_if_full(), btr_leaf_page_release(),
buf_page_make_young(): Replace page_t with buf_block_t.
btr_compress(): Replace btr_page_get() with btr_block_get().
