return the requested amount of memory.

to replace a built-in instance of InnoDB in mysqld.  This is work in
progress, with several limitations:

* Other plugins defined in the builtin InnoDB are not disabled.
  However, InnoDB in MySQL 5.1 only defines the storage engine plugin,
  no INFORMATION_SCHEMA plugins.

* The global C symbols in ha_innodb.so except innodb_hton_ptr and
  builtin_innobase_plugin will have to be redefined, e.g., by objcopy.

* The storage engine cannot be called "InnoDB" to avoid a conflict with
  the builtin name.  Here we call it InnoDBzip.

innobase_hton_name[]: Rename to "InnoDBzip" when building a dynamic plugin.

innodb_plugin_init(): New function for the dynamic plugin, to copy
and redirect configuration parameters from the builtin InnoDB.

innodb_dynamic: New configuration parameter.  This has to be added
to the builtin InnoDB in MySQL 5.1.  Also, innodb_hton_ptr must be made
global there.

innobase_init(): Interpret the parameter innodb_dynamic.

Makefile.am: Redefine class ha_innobase to ha_innodb by a preprocessor
define.  Apparently, C++ classes cannot be easily renamed by objcopy.

those SELECTs whose ORDER BY cannot possibly make use of an index.

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.

Add the proper macros for checking the correct latching order in trx
information_schema code.

Fix off-by-one error in ut_raw_to_hex().

Non-functional change: add a missed space in the output message.

Non-functional change: fix compiler warning:

buf0buf.ic:637: warning: assignment discards qualifiers from pointer target type

Non-functional change to improve readability.

 
Add ut_raw_to_hex() function to convert a raw binary strings to hex.
This is a monstrous, fine-tuned implementation.

Unfortunately, the patch seems to prevent MySQL from utilizing secondary
indexes in the ORDER BY clauses.  Thus, the test no longer checks if newly
created indexes are well-formed.

ChangeSet@1.2528.98.1  2007-08-02 12:45:56-07:00  igor@mysql.com

Fixed bug#28404.
This patch adds cost estimation for the queries with ORDER BY / GROUP BY
and LIMIT. 
If there was a ref/range access to the table whose rows were required
to be ordered in the result set the optimizer always employed this access
though a scan by a different index that was compatible with the required 
order could be cheaper to produce the first L rows of the result set.
Now for such queries the optimizer makes a choice between the cheapest
ref/range accesses not compatible with the given order and index scans
compatible with it.

Add diagnostic function ha_storage_get_size() to retrieve the amount of
memory used by a ha_storage_t object.

references uninitialized, because it causes bogus warnings since r1947.

dtuple_validate(): Detect uninitialized data.

page_cur_insert_rec_low(), page_cur_insert_rec_zip(): Assert that the
record being inserted is valid before and after insertion.

reports duplicate key values.  The reported value may depend on the
size of the main-memory merge sort buffer (row_merge_block_t).

INNODB_ZIP and INNODB_ZIP_RESET from ha_innodb.cc to i_s.cc.

plugin_author, END_OF_ST_FIELD_INFO, i_s_info: New common constants.

trx_i_s_common_deinit(): Renamed to i_s_common_deinit().

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.

buf_block_fix_inc(), and use it.

Remove bogus comment from ha_storage_empty().

Add const qualifier to the value returned by ha_storage_put().
It must not be changed as this will invalidate the hash.

buf_page_can_relocate(): Replace the incorrect __attribute__((const))
with __attribute__((pure)).
