UNIV_MEM_ASSERT_RW(): New macro, to check that the contents of a memory
area is defined.
UNIV_MEM_ASSERT_W(): New macro, to check that a memory area is writable.
UNIV_MEM_ASSERT_AND_FREE(): New macro, to check that the memory is
writable before declaring it free (unwritable). This replaces UNIV_MEM_FREE()
in many places.
mem_init_buf(): Check that the memory is writable, and declare it undefined.
mem_erase_buf(): Check that the memory is writable, and declare it freed.
and adapt some things.
Note that ha_innodb.cc depends on mysql_tmpfile() being declared in
<mysql/plugin.h>. Until the function is declared there, you can
uncomment the buggy definition of mysql_tmpfile in ha_innodb.cc.
Remove storage/innobase/*/Makefile.am. The whole compilation is driven by
storage/innobase/Makefile.am and storage/innobase/plug.in.
plug.in: Declare InnoDB as a dynamic plugin.
ha_innodb.h: Remove the declarations of many global variables. The variables
are no longer directly referenced outside of storage/innobase.
trx_t: Add the field trx->duplicates.
trx_create(): Initialize the fields trx->active_trans and trx->duplicates.
innobase_query_is_update(): Remove. Consult trx->duplicates instead.

Many files:
Removed "MySQL Finland AB & TCX DataKonsult AB" from copyright header
Adjusted year(s) in copyright header
Added GPL copyright text
The variable is initialized to zero, and after that it is only added to.
Maybe the one who introduced the variable srv_buf_pool_flushed overlooked
that there is a separate return statement for returning ULINT_UNDEFINED?
CPU-bound SELECT queries. (Bug #15815)
Fix: replace the mutex by one mutex protecting the 'flush list'
(and the free list) and several mutexes protecting portions of the
buffer pool, where we keep several indivudual LRU lists of pages.
This patch is from Sunny Bains and Heikki Tuuri.
structure is reserved for every index in the data dictionary cache.
(Bug #20877)
We could shrink the structure further to three 32-bit words or two
64-bit words by turning the remaining fields to bit-fields.
Unfortunately, the fields are not protected by any mutex, and thus we
would better keep each field aligned to a machine word.
btr_search_t, buf_block_t: Rename "ulint side" to "ibool left_side".
Remove BTR_SEARCH_LEFT_SIDE and BTR_SEARCH_RIGHT_SIDE, and also rename
some local variables and function parameters from "ulint side" to
"ibool left_side".
btr_search_t: Remove the unused fields last_search, n_direction, direction,
and modify_clock. Remove the unused constants BTR_SEA_NO_DIRECTION,
BTR_SEA_LEFT, BTR_SEA_RIGHT, and BTR_SEA_SAME_REC.
btr_search_t: Remove magic_n unless #defined UNIV_DEBUG. Turn an assertion
about the magic number into a debug assertion.
and lexer files). From now on, the following Emacs cc-mode settings apply
when indenting C function bodies in InnoDB:
(setq c-basic-offset 8)
(setq c-label-minimum-indentation 0)
(add-to-list 'c-offsets-alist '(c . 0))
(add-to-list 'c-offsets-alist '(label . [0]))
The indentation rules for function declarations still have not been
formalized, and they must be formatted manually.
Try to limit all lines to at most 79 characters (assuming TAB stops every
8 characters) by splitting lines before opening parenthesis, or at
string constants.
Fix some grammar mistakes in diagnostic output:
match to, match with -> match
found from -> found in
trying rename -> trying to rename
Fix an error in page_check_dir(): it said "supremum not pointed to"
when the infimum was not pointed to.
Enclose commented-out code snippets in #if 0 ... #endif instead of /* ... */.
Add (void*) casts to some %p parameters in fprintf() calls. Try to
split lines before a binary operator, not after one. (These three fixes
were not made everywhere.)
space id on the disk do not match those in the memory. Also write to
the error log if a page was read from the doublewrite buffer. The
doublewrite buffer should be only read by the lower-level function fil_io()
at database startup.
r340: Fix http://bugs.mysql.com/bug.php?id=18283 in ha_innodb.cc and
http://bugs.mysql.com/bug.php?id=18238 in InnoDB
r339: Remove disk space leak on update of BLOB columns (Bug #18252).
btr_cur_pessimistic_update(): Invoke rec_get_offsets() after
rec_set_field_extern_bits().
btr_store_big_rec_extern_fields(): Note that offsets will no longer be
valid after calling this function.
r338: Fix bug 18238 : check in pessimistic insert and update if the buffer
pool is exhausted by locks
new tablespaces created from now on.
btr_store_big_rec_extern_fields(): Set FIL_PAGE_TYPE to FIL_PAGE_TYPE_BLOB.
buf_page_print(): Decode FIL_PAGE_TYPE. Replace if-else with switch().
buf_page_create(): Set FIL_PAGE_PREV, FIL_PAGE_NEXT and FIL_PAGE_TYPE.
trx_sysf_create(): Set FIL_PAGE_TYPE to FIL_PAGE_TYPE_TRX_SYS.
Initialize TRX_SYS_RSEG_SPACE.
FIL_PAGE_TYPE: Document that the field cannot be relied on in older
versions of MySQL/InnoDB. Add new type codes.
ibuf_bitmap_page_init(): Document that the rest of the page is uninitialized.
ibuf_add_free_page(): Log the setting of FIL_PAGE_TYPE.
fsp_header_init(): Set FIL_PAGE_TYPE to FIL_PAGE_TYPE_FSP_HDR.
Initialize FSP_NOT_USED.
fsp_fill_free_list(): Set FIL_PAGE_TYPE to FIL_PAGE_TYPE_XDES.
fsp_alloc_seg_inode_page(): Set FIL_PAGE_TYPE to FIL_PAGE_INODE.
fseg_create_general(): Set FIL_PAGE_TYPE to FIL_PAGE_TYPE_SYS.
