Plugins included into bin release cannot be
installed on debug version of server
Ensure that the plugin files of the debug build
get into the optimized tree, so that they find
their way into the final RPMs.
The test case crashes and recovers the server twice, and while
recovering InnoDB sets innodb_file_format_check to different
format on second restart. This makes the test case clean up
check to fail.
We fix this by deploying the option "--innodb_file_format_check='ON'"
in slave startup configuration. This makes the innodb_file_format_check
to not change on secod restart.
SET autocommit=1 while XA transaction is active may
cause various side effects, including memory corruption
and server crash.
The problem is that SET autocommit=1 and further queries
attempt to commit local transaction, whereas XA transaction
is still active.
As local and XA transactions are mutually exclusive, this
patch forbids enabling autocommit mode while XA transaction
is active.

IF the build process was split into separate "debug" and
"optimized" builds
AND
the plugin files of the debug build got copied into
"plugin/debug/"
(both is done for MySQL release builds starting from 5.5.3),
THEN these debug plugin files are to be included in the
final binary package.
This change deals with the inclusion only,
the other parts are done in different changesets.
This is a fix specific for HPUX,
for which the compiler does not resolve properly dependencies
involving unused inline functions.
(See existing comments in mysql_thread.h)
In include/mysql/psi/mysql_thread.h,
the instrumentation helpers for mysql_prlock_*
uses the pr lock apis.
These apis are implemented in mysys/thr_rwlock.c,
which is not linked to client code.
As a result, the code does not link in libmysql_r, on HPUX.
The fix is to cut dependencies explicitely,
by introducing -DDISABLE_MYSQL_RWLOCK_H,
when building client code.
MySQL uses two source layouts when building : the bzr
layout and the source package layout.
The previous fix for bug 35250 contained 1 change that is
valid for both modes and a number of changes that are valid
only for the bzr source layout.
The important thing was to fix the source package layout.
And for this the change in configure.in was sufficient.
It's not trivial (and not requested by this bug) to support
VPATH builds from the bzr trees.
This is why the other changes are reverted and the change to
fix the VPATH build for source distributions is left intact.
The test case added in previous patch missed a RESET MASTER on
test start up. Without it, showing binary log contents can
sometimes show spurious entries from previously executed tests,
ultimately causing test failure - result mismatch.
The test file was added in:
revid:luis.soares@sun.com-20100224190153-k0bpdx9abe88uoo2
This patch also moves the test case into binlog_innodb_row.test
file. This way we avoid having yet another test file,
binlog_row_innodb_truncate.test, whose only purpose is to host
one test case. This had been actually suggested during original
patch review, but somehow the binlog_innodb_row was missed when
searching for a file to host the test case.
Ensure that we store the correct cached_field_type whenever we cache Field items
(in this case it allows us to compare dates as dates, rather than strings)
The problem was that killing a query during the optimization
phase of a subselect would lead to crashes. The root of the
problem is that the subselect execution engine ignores failures
(eg: killed) during the optimization phase (JOIN::optimize),
leading to a crash once the subquery is executed due to
partially initialized structures (in this case a join tab).
The optimal solution would be to cleanup certain optimizer
structures if the optimization phase fails, but currently
there is no infrastructure to properly to track and cleanup
the structures. To workaround the whole problem one somewhat
good solution is to avoid executing a subselect if the query
has been killed. Cutting short any problems caused by failures
during the optimization phase.
NULL column for NULL
The optimization to read MIN() and MAX() values from an
index did not properly handle comparisons with NULL
values. Fixed by giving up the particular optimization step
if there are non-NULL safe comparisons with NULL values, as
the result is NULL anyway.
Also, Oracle copyright notice was added to all files.
Base Tables
The type inferrence of a view column caused the result to be
interpreted as the wrong type: DATE colums were interpreted
as TIME and TIME as DATETIME. This happened because view
columns are represented by Item_ref objects as opposed to
Item_field's. Item_ref had no method for retrieving a TIME
value and thus was forced to depend on the default
implementation for any expression, which caused the
expression to be evaluated as a string and then parsed into
a TIME/DATETIME value.
Fixed by letting Item_ref classes forward the request for a
TIME value to the referred Item - which is a field in this
case - this reads the TIME value directly without
conversion.
index cardinalities=1
Parallel repair didn't poroperly update index cardinality
in certain cases.
When myisam_sort_buffer_size is not enough to store all
keys, index cardinality was updated before index was
actually written, when no index statistic is available.
(regression)
Problem was that partition pruning did not exclude the
last partition if the range was beyond it
(i.e. not using MAXVALUE)
Fix was to not include the last partition if the
partitioning function value was not within the partition
range.
The problem was that UNINSTALL PLUGIN wasn't performing privilege
checks before removing a plugin. Any user (including users without
any kind of privileges) could uninstall any plugin.
The solution is to verify if the user has the DELETE privilege for
the mysql.plugin table before uninstalling a plugin.
The problem is that Item_direct_view_ref which is inherited
from Item_ident updates orig_table_name and table_name with
the same values. The fix is introduction of new constructor
into Item_ident and up which updates orig_table_name and
table_name separately.
