r4036 | marko | 2009-01-26 22:33:20 +0200 (Mon, 26 Jan 2009) | 22 lines
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().

assertion failure that was accidentally introduced in r4036.
Instead of calling buf_block_get_frame(), which asserts that the

is safe, because changes of block->page.state are protected by
the buffer pool mutex, which we are holding.

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.

Revert our temporary fix for Bug#40360 Binlog related errors with binlog off
This bug was fixed in MySQL code.
Our fix went into r2944 and r2947, but this patch does not entirely revert
those revisions because we want to leave the test case that was introduced
and also r2944 itself reverted r2935 and r2936. So if we completely revert
r2944 and r2947 then we would loose the test and will restore r2935 and
r2936.

The config param innodb_thread_concurrency is dynamically set and is

the enter and exit time the behaviour becomes erratic.
The fix is not to use srv_thread_concurrency when exiting, instead use
the flag trx->declared_to_be_inside_innodb.

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

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

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.

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.
