columns without where/group
Simple SELECT with implicit grouping used to return many rows if
the query was ordered by the aggregated column in the SELECT
list. This was incorrect because queries with implicit grouping
should only return a single record.
The problem was that when JOIN:exec() decided if execution needed
to handle grouping, it was assumed that sum_func_count==0 meant
that there were no aggregate functions in the query. This
assumption was not correct in JOIN::exec() because the aggregate
functions might have been optimized away during JOIN::optimize().
The reason why queries without ordering behaved correctly was
that sum_func_count is only recalculated if the optimizer chooses
to use temporary tables (which it does in the ordered case).
Hence, non-ordered queries were correctly treated as grouped.
The fix for this bug was to remove the assumption that
sum_func_count==0 means that there is no need for grouping. This
was done by introducing variable "bool implicit_grouping" in the
JOIN object.
Difficult to debug due to lacking report
This does not solve the real issue, but extracts server log when it happens
Forst commit was incomplete, didn't cover all cases
Use ev_offset instead of 1 as the packet header offset when getting
log position from events for heartbeat
call reset_transmit_packet before calling send_heartbeat_event
The BINLOG statement was sharing too much code with the slave SQL thread, introduced with
the patch for Bug#32407. This caused statements to be logged with the wrong server_id, the
id stored inside the events of the BINLOG statement rather than the id of the running
server.
Fix by rearranging code a bit so that only relevant parts of the code are executed by
the BINLOG statement, and the server_id of the server executing the statements will
not be overrided by the server_id stored in the 'format description BINLOG statement'.
The problem was in incorrect handling of predicates involving
NULL as a constant value by the range optimizer.
For example, when creating a SEL_ARG node from a condition of
the form "field < const" (which would normally result in the
"NULL < field < const" SEL_ARG), the special case when "const"
is NULL was not taken into account, so "NULL < field < NULL"
was produced for the "field < NULL" condition.
As a result, SEL_ARG structures of this form could not be
further optimized which in turn could lead to incorrectly
constructed SEL_ARG trees. In particular, code assuming SEL_ARG
structures to always form a sequence of ordered disjoint
intervals could enter an infinite loop under some
circumstances.
Fixed by changing get_mm_leaf() so that for any sargable
predicate except "<=>" involving NULL as a constant, "empty"
SEL_ARG is returned, since such a predicate is always false.
Add an option to control whether the master should keep waiting
until timeout when it detected that there is no semi-sync slave
available.
The bool option 'rpl_semi_sync_master_wait_no_slave' is 1 by
defalt, and will keep waiting until timeout. When set to 0, the
master will switch to asynchronous replication immediately when
no semi-sync slave is available.
Semi-sync status were not reset by FLUSH STATUS, this was because
all semi-sync status variables are defined as SHOW_FUNC and FLUSH
STATUS could only reset SHOW_LONG type variables.
This problem is fixed by change all status variables that should
be reset by FLUSH STATUS from SHOW_FUNC to SHOW_LONG.
After the fix, the following status variables will be reset by
FLUSH STATUS:
Rpl_semi_sync_master_yes_tx
Rpl_semi_sync_master_no_tx
Note: normally, FLUSH STATUS itself will be written into binlog
and be replicated, so after FLUSH STATS, one of
Rpl_semi_sync_master_yes_tx
Rpl_semi_sync_master_no_tx
can be 1 dependent on the semi-sync status. So it's recommended
to use FLUSH NO_WRITE_TO_BINLOG STATUS to avoid this.
Errors when send reply to master should never cause the IO thread
to stop, because master can fall back to async replication if it
does not get reply from slave.
The problem is fixed by deliberately ignoring the return value of
slaveReply.
Semi-sync uses an extra connection from slave to master to send
replies, this is a normal client connection, and used a normal
SET query to set the reply information on master, which is visible
to user and may cause some confusion and complaining.
This problem is fixed by using the method of sending reply by
using the same connection that is used by master dump thread to
send binlog to slave. Since now the semi-sync plugins are integrated
with the server code, it is not a problem to use the internal net
interfaces to do this.
The master dump thread will mark the event requires a reply and
wait for the reply when the event just sent is the last event
of a transaction and semi-sync status is ON; And the slave will
send a reply to master when it received such an event that requires
a reply.

branches/zip: ut0ut.h: Do not #include "os0sync.h" #ifdef UNIV_HOTBACKUP.
Since r5872, the InnoDB Hot Backup build was broken.
Fix it by not defining any thread synchronization primitives in ut0ut.h.
InnoDB Hot Backup is a single-threaded program.
In MySQL when the mapping for space is changed to something other than
0x20 by defining a different collation, then space is not ignored when
comparing two strings.
This was happening because the function that performs the comparison
of two strings while ignoring ending spaces, was comparing the collation
value of a space with the ascii value of the ' ' character. This should
be changed to do comparison between the collated values.
A build "--without-server" fails if using "--with-ssl" (YaSSL)
The problem was the lack of directory "extra" in a build
which did not include the server.
low myisam_sort_buffer_size
Repair by sort (default) or parallel repair of a MyISAM table
(doesn't matter partitioned or not) as well as bulk inserts
and enable indexes some times didn't failover to repair with

The problem was that after unsuccessful attempt, data file was
closed. Whereas repair with key cache requires open data file.
Fixed by reopening data file.
Also fixed a valgrind warning, which may appear during repair
by sort or parallel repair with certain myisam_sort_buffer_size
number of rows and length of an index entry (very dependent).

by autoconf (based on IB_ATOMIC_MODE_* macros). Define the startup message
to be printed.
* In configure.in: check what user has chosen and if he has chosen
something that is not available, emit an error. If nothing has been chosen
explicitly by the user, auto select an option according to the described
logic in configure.in.

diagnostics. This was written in order to better track down
Issue #313 in InnoDB Hot Backup.
MLOG_LSN: A new redo log entry type, for recording the current log

Simplify the compile time checks by splittig them into 5 independent checks:
* Whether GCC atomics are available
* Whether pthread_t can be used by GCC atomics
* Whether Solaris libc atomics are available
* Whether pthread_t can be used by Solaris libs atomics
* Checking the size of pthread_t

branches/zip:
Move the check whether to include ut0auxconf.h before everything because
we are now even checking for GCC atomics, we relied on MySQL to define
this macro before.
r5869 | vasil | 2009-09-12 03:33:11 -0500 (Sat, 12 Sep 2009) | 15 lines
branches/zip:
Include ut0auxconf.h only if none of the macros it would define is defined.
The check when to include this header was outdated from the time when there
was only one macro involved.
Move the atomics checks that are in univ.i outside of
#if windows ... #else ... #endif
This simplifies the code and removes some duplicates like defining
HAVE_ATOMIC_BUILTINS if HAVE_WINDOWS_ATOMICS is defined in both branches.
Do not define the same macro HAVE_ATOMIC_PTHREAD_T for different events.
Instead define HAVE_IB_ATOMIC_PTHREAD_T_GCC and
HAVE_IB_ATOMIC_PTHREAD_T_SOLARIS.

branches/zip:
Define HAVE_ATOMIC_BUILTINS and INNODB_RW_LOCKS_USE_ATOMICS in os0sync.h
instead of in univ.i. The code expects os_*() macros to be present if
HAVE_ATOMIC_BUILTINS and INNODB_RW_LOCKS_USE_ATOMICS are defined. So define
them next to defining the os_*() macros.

Rename HAVE_SOLARIS_ATOMICS to HAVE_IB_SOLARIS_ATOMICS and

Explicitly include os0sync.h to the places where HAVE_ATOMIC_BUILTINS and
INNODB_RW_LOCKS_USE_ATOMICS are used to avoid potential problems.
covering index
When two range predicates were combined under an OR
predicate, the algorithm tried to merge overlapping ranges
into one. But the case when a range overlapped several other
ranges was not handled. This lead to
1) ranges overlapping, which gave repeated results and
2) a range that overlapped several other ranges was cut off.
Fixed by
1) Making sure that a range got an upper bound equal to the
next range with a greater minimum.
2) Removing a continue statement

Using the partition with most rows instead of first partition
to estimate the cardinality of indexes.
is reached
Problem was bad error handling, leaving some new temporary
partitions locked and initialized and some not yet initialized
and locked, leading to a crash when trying to unlock the not
yet initialized and locked partitions
Solution was to unlock the already locked partitions, and not
include any of the new temporary partitions in later unlocks
