branches/zip: When invoking page_zip_copy_recs(), update the lock table
and the adaptive hash index. This should fix Issue #95 and Issue #87.
page_zip_copy_recs(): Copy PAGE_MAX_TRX_ID as well, to have similar behavior
to page_copy_rec_list_start() and page_copy_rec_list_end().
btr_root_raise_and_insert(), btr_page_split_and_insert(), btr_lift_page_up():

branches/zip: When the server crashes while freeing an externally stored
column of a compressed table, the BTR_EXTERN_LEN field in the BLOB pointer
will be written as 0. Tolerate this in the functions that deal with
externally stored columns. This fixes Issue #80 and was posted at rb://26.
Note that the clustered index record is always deleted or purged last,
after any secondary index records referring to it have been deleted.
btr_free_externally_stored_field(): On an uncompressed table, zero out
the BTR_EXTERN_LEN, so that half-deleted BLOBs can be detected after
crash recovery.
btr_copy_externally_stored_field_prefix(): Return 0 if the BLOB has been
half-deleted.
row_upd_ext_fetch(): Assert that the externally stored column exists.
row_ext_cache_fill(): Allow btr_copy_externally_stored_field_prefix()
to return 0.
row_sel_sec_rec_is_for_blob(): Return FALSE if the BLOB has been half-deleted.
This is correct, because the clustered index record would have been deleted
or purged last, after any secondary index records referring to it had been
deleted.

btr_cur_optimistic_delete(): Split a too long line in the way it is
split in branches/zip.
buf_page_get_gen(): Add missing space in the function comment.
buf_print_io(): Restoer a removed space to the printout.
univ.i: Remove C++-style (or C99-style) comments.
buf0buf.h: Undo the white-space changes to the wrapper macros of
buf_page_get_gen().
ibuf_update_free_bits_low(): Revert the changes. Restore the assertion
that this function must not be invoked on compressed pages. The function
ibuf_update_free_bits_zip() is for compressed pages.
ibuf_insert_to_index_page(): Undo a white-space change.

include/innodb_redefine.h: Remove.
include/sync0sync.h: Remove the definition of mutex_free that was added
because of innodb_redefine.h.
include/univ.i: Remove references to innodb_redefine.h. Explain why
the C++ classes need to be renamed.

innodb_redefine.h is no longer needed.
symbols. Use it for all definitions of non-static variables and functions.
lexyy.c, make_flex.sh: Declare yylex as UNIV_INTERN, not static. It is
referenced from pars0grm.c.
Actually, according to
nm .libs/ha_innodb.so|grep -w '[ABCE-TVXYZ]'
the following symbols are still global:
* The vtable for class ha_innodb
* pars0grm.c: The function yyparse() and the variables yychar, yylval, yynerrs
The required changes to the Bison-generated file pars0grm.c will be addressed
in a separate commit, which will add a script similar to make_flex.sh.
The class ha_innodb is renamed from class ha_innobase by a #define. Thus,
there will be no clash with the builtin InnoDB. However, there will be some
overhead for invoking virtual methods of class ha_innodb. Ideas for making
the vtable hidden are welcome. -fvisibility=hidden is not available in GCC 3.
just one parameter: UNIV_PAGE_SIZE_SHIFT.
UNIV_PAGE_SIZE, BUF_BUDDY_SIZES: Define in terms of UNIV_PAGE_SIZE_SHIFT.
BUF_BUDDY_LOW_SHIFT: New macro, to simplify the definition of BUF_BUDDY_LOW
and BUF_BUDDY_SIZES.
PAGE_ZIP_DIR_SLOT_MASK: Relax the compile-time check. This bitmask must be
one less than a power of two, and at least UNIV_PAGE_SIZE - 1.
univ.i: Do not define UNIV_DEBUG, UNIV_ZIP_DEBUG.
btr_cur_del_unmark_for_ibuf(): Use the same comment in both btr0cur.c and
btr0cur.h. Wrap long lines.
contents end up with conflicting versions of a record's state. The zipped
page record was not being marked as "(un)deleted" because we were not
passing the zipped page contents to the (un)delete function, which first
(un)delete marks the uncompressed version and then based on whether
page_zip is NULL or not (un)delete marks the record in the compressed page.
redefined so that the dynamic plugin can replace the builtin InnoDB
in MySQL 5.1.
ha_innodb.cc, handler0alter.cc: #include "univ.i" before any other InnoDB
header files or before defining any symbols
innodb_redefine.h: New file, to contain a mapping of symbols. The idea
is that this file will be replaced in the build process; because this
is a large file that can be generated automatically, it does not make sense
to keep it under version control.
univ.i: #include "innodb_redefine.h" and #define ha_innobase ha_innodb
Makefile.am (ha_innodb_la_CXXFLAGS): Remove -Dha_innobase=ha_innodb
NOTE: there are still some issues in the source code. One known issue is
the #undef mutex_free in sync0sync.h, which will cause the plugin to call the
function mutex_free in the builtin InnoDB. The preprocessor symbols defined
in innodb_redefine.h must not be undefined or redefined anywhere in the code.
Add innodb_locks.lock_data column and some relevant tests.
For record locks this column represents the ordering fields of the
locked row in a human readable, SQL-valid, format.

UNIV_MEM_ASSERT_RW(): New macro, to check that the contents of a memory

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(): Declare the memory undefined.
mem_erase_buf(): Declare the memory freed.

#define INSIDE_HA_INNOBASE_CC: Remove.
srv_sizeof_trx_t_in_ha_innodb_cc: Remove.
dict_table_get_low_noninlined(): Remove. This function was unused.

of HASH_DELETE().
HASH_ASSERT_VALID(), HASH_INVALIDATE(): New macros, used in HASH_DELETE()
and HASH_SEARCH().
buf_page_init_low(): Add HASH_INVALIDATE(bpage, hash);
buf_page_init(): Call buf_page_init_low() before HASH_INSERT(), so that
bpage->hash will not be invalidated.
UNIV_MEM_FREE(): Declare a memory area free.
UNIV_MEM_ALLOC(): Declare a memory area allocated (but uninitialized).
UNIV_MEM_DESC(): Associate a memory area with a control block.
UNIV_MEM_UNDESC(): Unassociate a control block.
trx_sys_create_doublewrite_buf(): Clear the buffer with memset().
buf_page_init(): Add a bogus UNIV_MEM_VALID(block->frame) to silence
valid warnings about InnoDB data pages containing uninitialized data.
buf_LRU_get_free_only(): Add UNIV_MEM_ALLOC(block->frame).
buf_LRU_get_free_block(): Add UNIV_MEM_DESC(block->page.zip.data, block).
buf_LRU_free_block(): Add UNIV_MEM_DESC(b->zip.data, b) when allocating
a compressed-only control block for a compressed page.
buf_LRU_block_free_non_file_page(): Replace UNIV_MEM_INVALID() with
UNIV_MEM_FREE().
buf_LRU_block_remove_hashed_page(): Add UNIV_MEM_UNDESC(bpage) when
deallocating a compressed-only control block. Add
UNIV_MEM_INVALID(block->frame). (The frame should be flagged free
by buf_LRU_block_free_non_file_page() moments later.)
buf0buddy.c: Disable some extra checks in Valgrind-instrumented builds.
Add UNIV_MEM_VALID(), UNIV_MEM_INVALID(), UNIV_MEM_FREE(), UNIV_MEM_ALLOC()

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.
enclose all related debug code in #ifdef UNIV_DEBUG_FILE_ACCESSES.
This should have no effect on the behaviour, as the symbol is
not defined by default. It only reduces the size of buf_block_t
and removes some assignments and debug functions.
On POSIX, use mmap() and munmap(). On Windows, use VirtualAlloc()
and VirtualFree(). Only on Netware, use ut_malloc_low() and ut_free().
The lower-level functions on POSIX and Windows allow InnoDB to return
memory to the operating system when the buffer pool is shrunk.
for more accurate Valgrind debugging.
univ.i: Introduce UNIV_DEBUG_VALGRIND, UNIV_MEM_VALID, and UNIV_MEM_INVALID.
buf_LRU_block_free_non_file_page(): Invalidate the buffer frame
with UNIV_MEM_INVALID().
buf_LRU_get_free_block(): Declare the buffer frame valid
with UNIV_MEM_VALID().
Other memory is allocated and deallocated via malloc() and free(),
which are already overridden by Valgrind. Without the added
instrumentation, accesses to free pages in the buffer pool cannot
be caught.
The diagnostics could probably be improved further by declaring all
non-latched buffer frames invalid.
buf_flush_init_for_writing(): Improve the diagnostics and make the
condition for skipping pages accurate.
univ.i: Introduce UNIV_ZIP_DEBUG for enabling some page_zip_validate() tests.
page0zip.h, page0zip.c: Define and use page_zip_validate() in
page_zip_compress() and page_zip_write() if UNIV_ZIP_DEBUG or UNIV_DEBUG
is defined.
