Bug #33931 assertion at write_ignored_events_info_to_relay_log if init_slave_thread() fails
and
bug#33932 assertion at handle_slave_sql if init_slave_thread() fails
the asserts were caused by
bug33931: having thd deleted at time of executing err: code plus
a missed initialization;
bug33932: initialization of slave_is_running member was missed;
fixed with relocating mi members initialization and removing delete thd
It is safe to do as deletion happens later explicitly in the caller of
init_slave_thread().
Todo: at merging the test is better to be moved into suite/bugs for 5.x (when x>0).
sql/slave.cc:
adding the bugs simulating code;
relocating some assignments to satisfy the asserts;
mysql-test/r/rpl_bug33931.result:
the new result file
mysql-test/t/rpl_bug33931-slave.opt:
option to spark the simulation code
mysql-test/t/rpl_bug33931.test:
tests check that slave does not crash as before.
Slave threads must be in NO running state in the end.

Patch to eliminate some valgrind warnings in debug printout code.
sql/rpl_rli.cc: Adding variable to mark an instance of Relay_log_info as fake. sql/rpl_rli.h: Adding variable to mark an instance of Relay_log_info as fake. sql/slave.cc: Not printing debug information if we are working with a fake instance of Relay_log_info. This because the result of calling update is nonsense, and trying to print it generates valgrind warnings. sql/sql_binlog.cc: Marking newly created instance of Relay_log_info as a fake instance. |

Bug #34305 show slave status handling segfaults when slave io is about
to leave
The artifact was caused by
a flaw in concurrent accessing the slave's io thd by
the io itself and a handling show slave status thread.
Namely, show_master_info did not acquire mi->run_lock mutex that is
specified for mi->io_thd member.
Fixed with deploying the mutex locking and unlocking. The mutex is kept
short time and without interleaving with mi->data_lock mutex.
Todo: to report and fix an issue with
sys_var_slave_skip_counter::{methods}
seem to acquire incorrectly
active_mi->rli.run_lock
instead of the specified
active_mi->rli.data_lock
A test case is difficult to compose, so rpl_packet should continue serving
as the indicator.
sql/slave.cc:
implementing a TODO left at 4.1 time:
mending access to mi->io_thd with the specified mutex;
sql/slave.h:
adding a member name to the list of that run_lock guards.

BUG#12691 (Exec_master_log_pos corrupted with SQL_SLAVE_SKIP_COUNTER):
Complementary patch since LOAD DATA INFILE was not covered in the previous patch. This patch adds a check so that the slave skip counter is not decreased to zero if seeing a BEGIN_LOAD_QUERY_EVENT, APPEND_BLOCK_EVENT, or CREATE_FILE_EVENT since these cannot end a group. The group is terminated by an EXECUTE_LOAD_QUERY_ EVENT or DELETE_FILE_EVENT. mysql-test/r/rpl_slave_skip.result: Result change. mysql-test/t/rpl_slave_skip.test: Adding tests to test that the first event of a LOAD DATA INFILE can be skipped safely for both transactional and non-transactional tables. Also include a case that will generate a DELETE_FILE event last in the group, and this should be properly skipped as well. sql/slave.cc: Not decrementing slave skip counter to zero when seeing a BEGIN_LOAD_QUERY_EVENT, APPEND_BLOCK_EVENT, or CREATE_FILE_EVENT since these cannot end a group. |

BUG#32407: Impossible to do point-in-time recovery from older binlog
Problem: it is unsafe to read base64-printed events without first
reading the Format_description_log_event (FD). Currently, mysqlbinlog
cannot print the FD.
As a side effect, another bug has also been fixed: When mysqlbinlog
--start-position=X was specified, no ROLLBACK was printed. I changed
this, so that ROLLBACK is always printed.
This patch does several things:
- Format_description_log_event (FD) now print themselves in base64
format.
- mysqlbinlog is now able to print FD events. It has three modes:
--base64-output=auto Print row events in base64 output, and print
FD event. The FD event is printed even if
it is outside the range specified with
--start-position, because it would not be
safe to read row events otherwise. This is
the default.
--base64-output=always Like --base64-output=auto, but also print
base64 output for query events. This is
like the old --base64-output flag, which
is also a shorthand for
--base64-output=always
--base64-output=never Never print base64 output, generate error if
row events occur in binlog. This is
useful to suppress the FD event in binlogs
known not to contain row events (e.g.,
because BINLOG statement is unsafe,
requires root privileges, is not SQL, etc)
- the BINLOG statement now handles FD events correctly, by setting
the thread's rli's relay log's description_event_for_exec to the
loaded event.
In fact, executing a BINLOG statement is almost the same as reading
an event from a relay log. Before my patch, the code for this was
separated (exec_relay_log_event in slave.cc executes events from
the relay log, mysql_client_binlog_statement in sql_binlog.cc
executes BINLOG statements). I needed to augment
mysql_client_binlog_statement to do parts of what
exec_relay_log_event does. Hence, I did a small refactoring and
moved parts of exec_relay_log_event to a new function, which I
named apply_event_and_update_pos. apply_event_and_update_pos is
called both from exec_relay_log_event and from
mysql_client_binlog_statement.
- When a non-FD event is executed in a BINLOG statement, without
previously executing a FD event in a BINLOG statement, it generates
an error, because that's unsafe. I took a new error code for that:
ER_NO_FORMAT_DESCRIPTION_EVENT_BEFORE_BINLOG_STATEMENTS.
In order to get a decent error message containing the name of the
event, I added the class method char*
Log_event::get_type_str(Log_event_type type), which returns a
string name for the given Log_event_type. This is just like the
existing char* Log_event::get_type_str(), except it is a class
method that takes the log event type as parameter.
I also added PRE_GA_*_ROWS_LOG_EVENT to Log_event::get_type_str(),
so that names of old rows event are properly printed.
- When reading an event, I added a check that the event type is known
by the current Format_description_log_event. Without this, it may
crash on bad input (and I was struck by this several times).
- I patched the following test cases, which all contain BINLOG
statements for row events which must be preceded by BINLOG
statements for FD events:
- rpl_bug31076
While I was here, I fixed some small things in log_event.cc:
- replaced hard-coded 4 by EVENT_TYPE_OFFSET in 3 places
- replaced return by DBUG_VOID_RETURN in one place
- The name of the logfile can be '-' to indicate stdin. Before my
patch, the code just checked if the first character is '-'; now it
does a full strcmp(). Probably, all arguments that begin with a -
are already handled somewhere else as flags, but I still think it
is better that the code reflects what it is supposed to do, with as
little dependencies as possible on other parts of the code. If we
one day implement that all command line arguments after -- are
files (as most unix tools do), then we need this.
I also fixed the following in slave.cc:
- next_event() was declared twice, and queue_event was not static but
should be static (not used outside the file).
client/client_priv.h:
Declared the new option for base64 output.
client/mysqlbinlog.cc:
- Change from using the two-state command line option
"default/--base64-output" to the three-state
"--base64-output=[never|auto|always]"
- Print the FD event even if it is outside the --start-position range.
- Stop if a row event is about to be printed without a preceding FD
event.
- Minor fixes:
* changed 4 to EVENT_TYPE_OFFSET in some places
* Added comments
* before, "mysqlbinlog -xyz" read from stdin; now it does not
(only "mysqlbinlog -" reads stdin).
mysql-test/r/mysqlbinlog2.result:
Updated result file: mysqlbinlog now prints ROLLBACK always.
mysql-test/suite/binlog/t/disabled.def:
The test must be disabled since it reveals another bug: see BUG#33247.
mysql-test/suite/rpl/r/rpl_bug31076.result:
Updated result file
mysql-test/suite/rpl/r/rpl_row_mysqlbinlog.result:
Updated result file
mysql-test/suite/rpl/t/rpl_bug31076.test:
Had to add explicit Format_description_log_event before other BINLOG
statements
mysql-test/t/mysqlbinlog2.test:
we must suppress base64 output in result file because it contains a
timestamp
sql/log_event.cc:
- Made FD events able to print themselves
- Added check that the current FD event knows about the event type, when
an event is about to be read. (Hint to reviewers: I had to re-indent
a big block because of this; use diff -b)
* To get a decent error message, I also added a class method
const char* Log_event::get_type_str(Log_event_type)
which converts number to event type string without having a
Log_event object.
* Made Log_event::get_type_str aware of PRE_GA_*_ROWS_LOG_EVENT.
- Minor fixes:
* Changed return to DBUG_VOID_RETURN
sql/log_event.h:
- Declared enum to describe the three base64_output modes
- Use the enum instead of a flag
- Declare the new class method get_type_str (see log_event.cc)
sql/share/errmsg.txt:
Added error msg.
sql/slave.cc:
- Factored out part of exec_relay_log_event to the new function
apply_event_and_update_pos, because that code is needed when executing
BINLOG statements. (this is be functionally equivalent to the
previous code, except: (1) skipping events is now optional, controlled
by a parameter to the new function (2) the return value of
exec_relay_log_event has changed; see next item).
- Changed returned error value to always be 1. Before, it would return
the error value from apply_log_event, which was unnecessary. This
change is safe because the exact return value of exec_relay_log_event
is never examined; it is only tested to be ==0 or !=0.
- Added comments describing exec_relay_log_event and
apply_event_and_update_pos.
- Minor fixes:
* Removed duplicate declaration of next_event, made queue_event
static.
* Added doxygen code to include this file.
sql/slave.h:
Declared the new apply_event_and_update_pos
sql/sql_binlog.cc:
- Made mysql_binlog_statement set the current FD event when the given
event is an FD event. This entails using the new function
apply_event_and_update_pos from slave.cc instead of just calling the
ev->apply method.
- Made mysql_binlog_statement fail if the first BINLOG statement is not
an FD event.
mysql-test/suite/binlog/r/binlog_base64_flag.result:
New test file needs new result file
mysql-test/suite/binlog/t/binlog_base64_flag.test:
Added test case to verify that:
- my patch fixes the bug
- the new --base64-output flag works as expected
- base64 events not preceded by an FD event give an error
- an event of a type not known by the current FD event fails cleanly.

Bug#12713 "Error in a stored function called from a SELECT doesn't
cause ROLLBACK of statement", part 1. Review fixes.
Do not send OK/EOF packets to the client until we reached the end of
the current statement.
This is a consolidation, to keep the functionality that is shared by all
SQL statements in one place in the server.
Currently this functionality includes:
- close_thread_tables()
- log_slow_statement().
After this patch and the subsequent patch for Bug#12713, it shall also include:
- ha_autocommit_or_rollback()
- net_end_statement()
- query_cache_end_of_result().
In future it may also include:
- mysql_reset_thd_for_next_command().
include/mysql_com.h:
Rename now unused members of NET: no_send_ok, no_send_error, report_error.
These were server-specific variables related to the client/server
protocol. They have been made obsolete by this patch.
Previously the same members of NET were used to store the error message
both on the client and on the server.
The error message was stored in net.last_error (client: mysql->net.last_error,
server: thd->net.last_error).
The error code was stored in net.last_errno (client: mysql->net.last_errno,
server: thd->net.last_errno).
The server error code and message are now stored elsewhere
(in the Diagnostics_area), thus NET members are no longer used by the
server.
Rename last_error to client_last_error, last_errno to client_last_errno
to avoid potential bugs introduced by merges.
include/mysql_h.ic:
Update the ABI file to reflect a rename.
Renames do not break the binary compatibility.
libmysql/libmysql.c:
Rename last_error to client_last_error, last_errno to client_last_errno.
This is necessary to ensure no unnoticed bugs introduced by merged
changesets.
Remove net.report_error, net.no_send_ok, net.no_send_error.
libmysql/manager.c:
Rename net.last_errno to net.client_last_errno.
libmysqld/lib_sql.cc:
Rename net.last_errno to net.client_last_errno.
Update the embedded implementation of the client-server protocol to
reflect the refactoring of protocol.cc.
libmysqld/libmysqld.c:
Rename net.last_errno to net.client_last_errno.
mysql-test/r/events.result:
Update to reflect the change in mysql_rm_db(). Now we drop stored
routines and events for a given database name only if there
is a directory for this database name. ha_drop_database() and
query_cache_invalidate() are called likewise.
Previously we would attempt to drop routines/events even if database
directory was not found (it worked, since routines and events are stored
in tables). This fixes Bug 29958 "Weird message on DROP DATABASE if mysql.proc
does not exist".
The change was done because the previous code used to call send_ok()
twice, which led to an assertion failure when asserts against it were
added by this patch.
mysql-test/r/grant.result:
Fix the patch for Bug 16470, now FLUSH PRIVILEGES produces an error
if mysql.procs_priv is missing.
This fixes the assert that send_ok() must not called after send_error()
(the original patch for Bug 16470 was prone to this).
mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result:
Produce a more detailed error message.
mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result:
Produce a more detailed error message.
mysql-test/t/grant.test:
Update the test, now FLUSH PRIVILEGES returns an error if mysql.procs_priv
is missing.
server-tools/instance-manager/mysql_connection.cc:
Rename net.last_errno to net.client_last_errno.
sql/ha_ndbcluster_binlog.cc:
Add asserts.
Use getters to access statement status information.
Add a comment why run_query() is broken. Reset the diagnostics area
in the end of run_query() to fulfill the invariant that the diagnostics_area
is never assigned twice per statement (see the comment in the code
when this can happen). We still do not clear thd->is_fatal_error and
thd->is_slave_error, which may lead to bugs, I consider the whole affair
as something to be dealt with separately.
sql/ha_partition.cc:
fatal_error() doesn't set an error by itself. Perhaps we should
remove this method altogether and instead add a flag to my_error
to set thd->is_fatal_error property.
Meanwhile, this change is a part of inspection made to the entire source
code with the goal to ensure that fatal_error()
is always accompanied by my_error().
sql/item_func.cc:
There is no net.last_error anymore. Remove the obsolete assignment.
sql/log_event.cc:
Use getters to access statement error status information.
sql/log_event_old.cc:
Use getters to access statement error status information.
sql/mysqld.cc:
Previously, if a continue handler for an error was found, my_message_sql()
would not set an error in THD. Since the current statement
must be aborted in any case, find_handler() had a hack to assign
thd->net.report_error to 1.
Remove this hack. Set an error in my_message_sql() even if the continue
handler is found. The error will be cleared anyway when the handler
is executed. This is one action among many in this patch to ensure the
invariant that whenever thd->is_error() is TRUE, we have a message in
thd->main_da.message().
sql/net_serv.cc:
Use a full-blown my_error() in net_serv.cc to report an error,
instead of just setting net->last_errno. This ensures the invariant that
whenever thd->is_error() returns TRUE, we have a message in
thd->main_da.message().
Remove initialization of removed NET members.
sql/opt_range.cc:
Use my_error() instead of just raising thd->net.report_error.
This ensures the invariant that whenever thd->is_error() returns TRUE,
there is a message in thd->main_da.message().
sql/opt_sum.cc:
Move invocation of fatal_error() right next to the place where
we set the error message. That makes it easier to track that whenever
fatal_error() is called, there is a message in THD.
sql/protocol.cc:
Rename send_ok() and send_eof() to net_send_ok() and net_send_eof()
respectively. These functions write directly to the network and are not
for use anywhere outside the client/server protocol code.
Remove the code that was responsible for cases when either there is
no error code, or no error message, or both.
Instead the calling code ensures that they are always present. Asserts
are added to enforce the invariant.
Instead of a direct access to thd->server_status and thd->total_warn_count
use function parameters, since these from now on don't always come directly
from THD.
Introduce net_end_statement(), the single-entry-point replacement API for
send_ok(), send_eof() and net_send_error().
Implement Protocol::end_partial_result_set to use in select_send::abort()
when there is a continue handler.
sql/protocol.h:
Update declarations.
sql/repl_failsafe.cc:
Use getters to access statement status information in THD.
Rename net.last_error to net.client_last_error.
sql/rpl_record.cc:
Set an error message in prepare_record() if there is no default
value for the field -- later we do print this message to the client.
sql/rpl_rli.cc:
Use getters to access statement status information in THD.
sql/slave.cc:
In create_table_from_dump() (a common function that is used in
LOAD MASTER TABLE SQL statement and COM_LOAD_MASTER_DATA), instead of hacks
with no_send_ok, clear the diagnostics area when mysql_rm_table() succeeded.
Update has_temporary_error() to work correctly when no error is set.
This is the case when Incident_log_event is executed: it always returns
an error but does not set an error message.
Use getters to access error status information.
sql/sp_head.cc:
Instead of hacks with no_send_error, work through the diagnostics area
interface to suppress sending of OK/ERROR packets to the client.
Move query_cache_end_of_result before log_slow_statement(), similarly
to how it's done in dispatch_command().
sql/sp_rcontext.cc:
Remove hacks with assignment of thd->net.report_error, they are not
necessary any more (see the changes in mysqld.cc).
sql/sql_acl.cc:
Use getters to access error status information in THD.
sql/sql_base.cc:
Access thd->main_da.sql_errno() only if there is an error. This fixes
a bug when auto-discovery, that was effectively disabled under pre-locking.
sql/sql_binlog.cc:
Remove hacks with no_send_ok/no_send_error, they are not necessary
anymore: the caller is responsible for network communication.
sql/sql_cache.cc:
Disable sending of OK/ERROR/EOF packet in the end of dispatch_command
if the response has been served from the query cache. This raises the
question whether we should store EOF packet in the query cache at all,
or generate it anew for each statement (we should generate it anew), but
this is to be addressed separately.
sql/sql_class.cc:
Implement class Diagnostics_area. Please see comments in sql_class.h
for details.
Fix a subtle coding mistake in select_send::send_data: when on slave,
an error in Item::send() was ignored.
The problem became visible due to asserts that the diagnostics area is
never double assigned.
Remove initialization of removed NET members.
In select_send::abort() do not call select_send::send_eof(). This is
not inheritance-safe. Even if a stored procedure continue handler is
found, the current statement is aborted, not succeeded.
Instead introduce a Protocol API to send the required response,
Protocol::end_partial_result_set().
This simplifies implementation of select_send::send_eof(). No need
to add more asserts that there is no error, there is an assert inside
Diagnostics_area::set_ok_status() already.
Leave no trace of no_send_* in the code.
sql/sql_class.h:
Declare class Diagnostics_area.
Remove the hack with no_send_ok from
Substatement_state.
Provide inline implementations of send_ok/send_eof.
Add commetns.
sql/sql_connect.cc:
Remove hacks with no_send_error.
Since now an error in THD is always set if net->error, it's not necessary
to check both net->error and thd->is_error() in the do_command loop.
Use thd->main_da.message() instead of net->last_errno.
Remove the hack with is_slave_error in sys_init_connect. Since now we do not
reset the diagnostics area in net_send_error (it's reset at the beginning
of the next statement), we can access it safely even after
execute_init_command.
sql/sql_db.cc:
Update the code to satisfy the invariant that the diagnostics area is never
assigned twice.
Incidentally, this fixes Bug 29958 "Weird message on DROP DATABASE if
mysql.proc does not exist".
sql/sql_delete.cc:
Change multi-delete to abort in abort(), as per select_send protocol.
Fixes the merge error with the test for Bug 29136
sql/sql_derived.cc:
Use getters to access error information.
sql/sql_insert.cc:
Use getters to access error information.
sql-common/client.c:
Rename last_error to client_last_error, last_errno to client_last_errno.
sql/sql_parse.cc:
Remove hacks with no_send_error. Deploy net_end_statement().
The story of COM_SHUTDOWN is interesting. Long story short, the server
would become on its death's door, and only no_send_ok/no_send_error assigned
by send_ok()/net_send_error() would hide its babbling from the client.
First of all, COM_QUIT does not require a response. So, the comment saying
"Let's send a response to possible COM_QUIT" is not only groundless
(even mysqladmin shutdown/mysql_shutdown() doesn't send COM_QUIT after
COM_SHUTDOWN), it's plainly incorrect.
Secondly, besides this additional 'OK' packet to respond to a hypothetical
COM_QUIT, there was the following code in dispatch_command():
if (thd->killed)
thd->send_kill_message();
if (thd->is_error()
net_send_error(thd);
This worked out really funny for the thread through which COM_SHUTDOWN
was delivered: we would get COM_SHUTDOWN, say okay, say okay again,
kill everybody, get the kill signal ourselves, and then attempt to say
"Server shutdown in progress" to the client that is very likely long gone.
This all became visible when asserts were added that the Diagnostics_area
is not assigned twice.
Move query_cache_end_of_result() to the end of dispatch_command(), since
net_send_eof() has been moved there. This is safe, query_cache_end_of_result()
is a no-op if there is no started query in the cache.
Consistently use select_send interface to call abort() or send_eof()
depending on the operation result.
Remove thd->fatal_error() from reset_master(), it was a no-op.
in hacks with no_send_error woudl save us
from complete breakage of the client/server protocol.
Consistently use select_send::abort() whenever there is an error,
and select_send::send_eof() in case of success.
The issue became visible due to added asserts.
sql/sql_partition.cc:
Always set an error in THD whenever there is a call to fatal_error().
sql/sql_prepare.cc:
Deploy class Diagnostics_area.
Remove the unnecessary juggling with the protocol in
Select_fetch_protocol_binary::send_eof(). EOF packet format is
protocol-independent.
sql/sql_select.cc:
Call fatal_error() directly in opt_sum_query.
Call my_error() whenever we call thd->fatal_error().
sql/sql_servers.cc:
Use getters to access error information in THD.
sql/sql_show.cc:
Use getters to access error information in THD.
Add comments.
Call my_error() whenever we call fatal_error().
sql/sql_table.cc:
Replace hacks with no_send_ok with the interface of the diagnostics area.
Clear the error if ENOENT error in ha_delete_table().
sql/sql_update.cc:
Introduce multi_update::abort(), which is the proper way to abort a
multi-update. This fixes the merge conflict between this patch and
the patch for Bug 29136.
sql/table.cc:
Use a getter to access error information in THD.
sql/tztime.cc:
Use a getter to access error information in THD.

Fix for bug #29976: Excessive Slave I/O errors in replication tests
Problem: The "Slave I/O thread couldn't register on master" error sporadically occurred in replication tests because the slave I/O thread got killed by STOP SLAVE before or while registering on master. Fixed by checking the state of the I/O thread, and issueing the error only if it was not explicitely killed by a user. sql/slave.cc: When the slave I/O thread fails to register on master, issue an error message only if it is not explicitely killed by a user with STOP SLAVE. |

Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
Bug 26867 - LOCK TABLES + REPAIR + merge table result in
memory/cpu hogging
Bug 26377 - Deadlock with MERGE and FLUSH TABLE
Bug 25038 - Waiting TRUNCATE
Bug 25700 - merge base tables get corrupted by
optimize/analyze/repair table
Bug 30275 - Merge tables: flush tables or unlock tables
causes server to crash
Bug 19627 - temporary merge table locking
Bug 27660 - Falcon: merge table possible
Bug 30273 - merge tables: Can't lock file (errno: 155)
The problems were:
Bug 26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
1. A thread trying to lock a MERGE table performs busy waiting while
REPAIR TABLE or a similar table administration task is ongoing on
one or more of its MyISAM tables.
2. A thread trying to lock a MERGE table performs busy waiting until all
threads that did REPAIR TABLE or similar table administration tasks
on one or more of its MyISAM tables in LOCK TABLES segments do UNLOCK
TABLES. The difference against problem #1 is that the busy waiting
takes place *after* the administration task. It is terminated by
UNLOCK TABLES only.
3. Two FLUSH TABLES within a LOCK TABLES segment can invalidate the
lock. This does *not* require a MERGE table. The first FLUSH TABLES
can be replaced by any statement that requires other threads to
reopen the table. In 5.0 and 5.1 a single FLUSH TABLES can provoke
the problem.
Bug 26867 - LOCK TABLES + REPAIR + merge table result in
memory/cpu hogging
Trying DML on a MERGE table, which has a child locked and
repaired by another thread, made an infinite loop in the server.
Bug 26377 - Deadlock with MERGE and FLUSH TABLE
Locking a MERGE table and its children in parent-child order
and flushing the child deadlocked the server.
Bug 25038 - Waiting TRUNCATE
Truncating a MERGE child, while the MERGE table was in use,
let the truncate fail instead of waiting for the table to
become free.
Bug 25700 - merge base tables get corrupted by
optimize/analyze/repair table
Repairing a child of an open MERGE table corrupted the child.
It was necessary to FLUSH the child first.
Bug 30275 - Merge tables: flush tables or unlock tables
causes server to crash
Flushing and optimizing locked MERGE children crashed the server.
Bug 19627 - temporary merge table locking
Use of a temporary MERGE table with non-temporary children
could corrupt the children.
Temporary tables are never locked. So we do now prohibit
non-temporary chidlren of a temporary MERGE table.
Bug 27660 - Falcon: merge table possible
It was possible to create a MERGE table with non-MyISAM children.
Bug 30273 - merge tables: Can't lock file (errno: 155)
This was a Windows-only bug. Table administration statements
sometimes failed with "Can't lock file (errno: 155)".
These bugs are fixed by a new implementation of MERGE table open.
When opening a MERGE table in open_tables() we do now add the
child tables to the list of tables to be opened by open_tables()
(the "query_list"). The children are not opened in the handler at
this stage.
After opening the parent, open_tables() opens each child from the
now extended query_list. When the last child is opened, we remove
the children from the query_list again and attach the children to
the parent. This behaves similar to the old open. However it does
not open the MyISAM tables directly, but grabs them from the already
open children.
When closing a MERGE table in close_thread_table() we detach the
children only. Closing of the children is done implicitly because
they are in thd->open_tables.
For more detail see the comment at the top of ha_myisammrg.cc.
Changed from open_ltable() to open_and_lock_tables() in all places
that can be relevant for MERGE tables. The latter can handle tables
added to the list on the fly. When open_ltable() was used in a loop
over a list of tables, the list must be temporarily terminated
after every table for open_and_lock_tables().
table_list->required_type is set to FRMTYPE_TABLE to avoid open of
special tables. Handling of derived tables is suppressed.
These details are handled by the new function
open_n_lock_single_table(), which has nearly the same signature as
open_ltable() and can replace it in most cases.
In reopen_tables() some of the tables open by a thread can be
closed and reopened. When a MERGE child is affected, the parent
must be closed and reopened too. Closing of the parent is forced
before the first child is closed. Reopen happens in the order of
thd->open_tables. MERGE parents do not attach their children
automatically at open. This is done after all tables are reopened.
So all children are open when attaching them.
Special lock handling like mysql_lock_abort() or mysql_lock_remove()
needs to be suppressed for MERGE children or forwarded to the parent.
This depends on the situation. In loops over all open tables one
suppresses child lock handling. When a single table is touched,
forwarding is done.
Behavioral changes:
===================
This patch changes the behavior of temporary MERGE tables.
Temporary MERGE must have temporary children.
The old behavior was wrong. A temporary table is not locked. Hence
even non-temporary children were not locked. See
Bug 19627 - temporary merge table locking.
You cannot change the union list of a non-temporary MERGE table
when LOCK TABLES is in effect. The following does *not* work:
CREATE TABLE m1 ... ENGINE=MRG_MYISAM ...;
LOCK TABLES t1 WRITE, t2 WRITE, m1 WRITE;
ALTER TABLE m1 ... UNION=(t1,t2) ...;
However, you can do this with a temporary MERGE table.
You cannot create a MERGE table with CREATE ... SELECT, neither
as a temporary MERGE table, nor as a non-temporary MERGE table.
CREATE TABLE m1 ... ENGINE=MRG_MYISAM ... SELECT ...;
Gives error message: table is not BASE TABLE.

Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
Defined new functions add_merge_table_list(),
attach_merge_children(), detach_merge_children(), and
fix_merge_after_open() for the new MERGE table open approach.
Added calls of the new functions to

in close_data_files_and_morph_locks().
Added code for re-attaching children in reopen_tables().
Added MYSQL_LOCK_NOTIFY_IF_NEED_REOPEN to the locking flags and
error reporting after mysql_lock_tables() in reopen_tables().
Added lock handling and closing of a parent before the children
in close_old_data_files().
Added lock handling and detaching in drop_locked_tables().
Added code for removing the children list from the statement list
to prepare for a repetition in open_tables().
Added new function open_n_lock_single_table(), which can be used
as an replacement for open_ltable() in most situations. Internally
it calls simple_open_n_lock_tables() so hat it is appropriate for

Bug#31210 - INSERT DELAYED crashes server when used on
partitioned table
Trying INSERT DELAYED on a partitioned table, that has not been
used right before, crashes the server. When a table is used for
select or update, it is kept open for some time. This period I
mean with "right before".
Information about partitioning of a table is stored in form of
a string in the .frm file. Parsing of this string requires a
correctly set up lexical analyzer (lex). The partitioning code
uses a new temporary instance of a lex. But it does still refer
to the previously active lex. The delayd insert thread does not
initialize its lex though...
Added initialization for thd->lex before open table in the delayed
thread and at all other places where it is necessary to call
lex_start() if all tables would be partitioned and need to parse
the .frm file.

Bug#30882 Dropping a temporary table inside a stored function may cause a server crash
If a stored function that contains a drop temporary table statement is invoked by a create temporary table of the same name may cause a server crash. The problem is that when dropping a table no check is done to ensure that table is not being used by some outer query (or outer statement), potentially leaving the outer query with a reference to a stale (freed) table. The solution is when dropping a temporary table, always check if the table is being used by some outer statement as a temporary table can be dropped inside stored procedures. The check is performed by looking at the TABLE::query_id value for temporary tables. To simplify this check and to solve a bug related to handling of temporary tables in prelocked mode, this patch changes the way in which this member is used to track the fact that table is used/unused. Now we ensure that TABLE::query_id is zero for unused temporary tables (which means that all temporary tables which were used by a statement should be marked as free for reuse after it's execution has been completed). mysql-test/include/handler.inc: Add test case for side effect of Bug#30882 mysql-test/r/handler_innodb.result: Add test case result for side effect of Bug#30882 mysql-test/r/handler_myisam.result: Add test case result for side effect of Bug#30882 mysql-test/r/sp-error.result: Add test case result for Bug#30882 mysql-test/t/sp-error.test: Add test case for Bug#30882 sql/event_db_repository.cc: Update close_thread_tables call, no more default values. sql/mysql_priv.h: Remove implicit default parameters values of the close_thread_tables function as no callers are using it. sql/slave.cc: Update close_thread_tables call, no more default values sql/sp_head.cc: Update close_thread_tables call, no more default values sql/sql_base.cc: Changed the approach to distinguishing currently unused temporary tables. Now we ensure that such tables always have TABLE::query_id set to 0 and use this fact to perform checks during opening and dropping of temporary tables. This means that we have to call close_thread_tables() even for statements which use only temporary tables. To make this call cheaper, we re-factored close_thread_tables() to not take LOCK_open unless there are open base tables. sql/sql_handler.cc: Properly close temporary tables associated with a handler. sql/sql_insert.cc: close_temporary_table is now merged into drop_temporary_table. sql/sql_parse.cc: Now the condition doesn't cover all cases because close_thread_tables() must be called even for statements that use only temporary tables. sql/sql_table.cc: Use drop_temporary_table which perform checks to verify if the table is not being used. Error path problem is due to a handler tables issue and is going to be addressed in bug 31397. sql/table.h: Rename previously unused clear_query_id and document the usage of query_id and open_by_handler. |

BUG#28618 (Skipping into the middle of a group with SQL_SLAVE_SKIP_COUNTER
is possible): When skipping the beginning of a transaction starting with BEGIN, the OPTION_BEGIN flag was not set correctly, which caused the slave to not recognize that it was inside a group. This patch sets the OPTION_BEGIN flag for BEGIN, COMMIT, ROLLBACK, and XID events. It also adds checks if inside a group before decreasing the slave skip counter to zero. Begin_query_log_event was not marked that it could not end a group, which is now corrected. mysql-test/extra/rpl_tests/rpl_extraSlave_Col.test: Correcting slave skip counter to get the correct behaviour. mysql-test/suite/rpl/r/rpl_slave_skip.result: Result change. mysql-test/suite/rpl/t/rpl_slave_skip.test: Adding tests to check that skipping works for transactions: - Skipping one group with BEGIN first - Skipping two groups with BEGIN first - Skipping one group without BEGIN first but with AUTOCOMMIT=0 - LOAD DATA INFILE under statement-based replication mysql-test/suite/rpl_ndb/r/rpl_ndb_extraCol.result: Result change. sql/log_event.cc: Adding checks if we're in a group when the slave skip counter is 1.

Adding helping member function Log_event::continue_group() denoting that this event cannot end a group, and if the skip counter indicates that the group ends after this event, it should not decrease the skip counter. Query_log_event will change the OPTION_BEGIN flag for BEGIN, COMMIT, and ROLLBACK, even when skipping because of a positive skip count, and Xid_log_event will also affect the OPTION_BEGIN flag, even when being skipped. Begin_load_query_log_event cannot end a group, so it is marked to continue the group. sql/log_event.h: Adding helper function Log_event::continue_group(). sql/rpl_rli.h: Adding Relay_log_info::get_flag() to get the value of a replication flag. sql/slave.cc: Adding debug output and changing debug message. mysql-test/suite/rpl/data/rpl_bug28618.dat: New BitKeeper file ``mysql-test/suite/rpl/data/rpl_bug28618.dat'' mysql-test/suite/rpl/t/rpl_slave_skip-slave.opt: New BitKeeper file ``mysql-test/suite/rpl/t/rpl_slave_skip-slave.opt'' |

Bug #29309 Incorrect "Seconds_Behind_Master" value in SHOW SLAVE STATUS after FLUSH LOGS
Report claims that Seconds_behind_master behaves unexpectedly. Code analysis shows that there is an evident flaw in that treating of FormatDescription event is wrong so that after FLUSH LOGS on slave the Seconds_behind_master's calculation slips and incorrect value can be reported to SHOW SLAVE STATUS. Even worse is that the gap between the correct and incorrect deltas grows with time. Fixed with prohibiting changes to rpl->last_master_timestamp by artifical events (any kind of). suggestion as comments is added how to fight with lack of info on the slave side by means of new heartbeat feature coming. The test can not be done ealily fully determistic. sql/log_event.cc: changing timestamp is affirmed only by non-artificial events. Artifical FD won't change it anymore. The simulation code is off unless server is started with the args from the opt-file. The simulation code assumes that it will execute specific schedule generated by rpl_replication_delay.test. sql/slave.cc: Comments are changed to announce a new possibility to cope with Seconds_behind_master jumping due to EOF special treatment (reset of the timestamp) mysql-test/suite/manual/r/rpl_replication_delay.result: result are not deterministic though there are comments saying the most probable expected value for Seconds_behind_master mysql-test/suite/manual/t/rpl_replication_delay-slave.opt: bug emulation mysql-test/suite/manual/t/rpl_replication_delay.test: specic test for bug#29309. It's hard to make it reliable as it deals with timestamps. (a way to automate the test like this is to have I_S table for show slave status' fields) A possible way to check results is to run grep -i 'show\|seconds' < suite/manual/r/rpl_replication_delay.reject and to get the lines like these: show slave status /* Second_behind reports 0 */;; Seconds_Behind_Master 0 show slave status /* bug emulated: reports slave threads starting time about 3*3 not 3 secs */;; Seconds_Behind_Master 9 show slave status /* reports the correct diff with master query time about 3+3 secs */;; Seconds_Behind_Master 6 Due to time discreteness of time the reported numbers may slightly vary. That's why the test is not reliable. |

BUG#29968 (rpl_ndb_circular.test and rpl_ndb_log.test fail):
Removing unguarded read of slave_running field from inside terminate_slave_threads(). This could cause premature exit in the event that the slave thread already were shutting down, but isn't finished yet. The fields slave_running, io_thd, and sql_thread are guarded by an associated run_lock. A read of these fields were not guarded inside terminate_slave_threads(), which caused an assertion to fire. The assertion was removed, and the code reorganized slightly. sql/slave.cc: Changing signature of terminate_slave_thread() to accept a skip_lock parameter instead of two mutexes. This mimics the signature of the terminate_slave_threads() function. Code is also changed as a result of this. Removing unguarded check of slave_running field in the master info and relay log info structure since that could cause premature exit of terminate_slave_threads(). The thread variable for each of the slave threads can change before acquiring the run_lock mutex inside terminate_slave_thread(). Hence an assertion was removed that read the variable without guarding it with run_lock. Code that checked *slave_running status inside terminate_slave_thread() was reorganized slightly. sql/slave.h: Moving terminate_slave_thread() to use internal linkage. |
