The crash appeared to be a result of allocating an instance of Discrete_interval automatically that that was referred in out-of-declaration scope. Fixed with correcting backing up and restoring scheme of auto_inc_intervals_forced, introduced by bug#33029, by means of shallow copying; added simulation code that forces executing those fixes of the former bug that targeted at master-and-slave having incompatible bug#33029-prone versions. mysql-test/suite/bugs/r/rpl_bug33029.result: new results file mysql-test/suite/bugs/t/rpl_bug33029.test: test merely checks no crash happens on slave. sql/slave.cc: forcing to execute special logics implemented for bug#33029 if simulate_bug33029 the debug option is set. sql/sql_class.cc: swaps of backed and the actual auto_inc_intervals_forced basing on shallow coping. sql/structs.h: Removing the deep _copy() and methods associated with it; adding methods to Discrete_intervals_list: private `=', copy constructor to prevent using; private set_members(); public copy_shallow(), swap(), get_{head, tail, current}(); empty_no_free() through set_members().

using a trig in SP For all 5.0 and up to 5.1.12 exclusive, when a stored routine or trigger caused an INSERT into an AUTO_INCREMENT column, the generated AUTO_INCREMENT value should not be written into the binary log, which means if a statement does not generate AUTO_INCREMENT value itself, there will be no Intvar event (SET INSERT_ID) associated with it even if one of the stored routine or trigger caused generation of such a value. And meanwhile, when executing a stored routine or trigger, it would ignore the INSERT_ID value even if there is a INSERT_ID value available set by a SET INSERT_ID statement. Starting from MySQL 5.1.12, the generated AUTO_INCREMENT value is written into the binary log, and the value will be used if available when executing the stored routine or trigger. Prior fix of this bug in MySQL 5.0 and prior MySQL 5.1.12 (referenced as the buggy versions in the text below), when a statement that generates AUTO_INCREMENT value by the top statement was executed in the body of a SP, all statements in the SP after this statement would be treated as if they had generated AUTO_INCREMENT by the top statement. When a statement that did not generate AUTO_INCREMENT value by the top statement but by a function/trigger called by it, an erroneous Intvar event would be associated with the statement, this erroneous INSERT_ID value wouldn't cause problem when replicating between masters and slaves of 5.0.x or prior 5.1.12, because the erroneous INSERT_ID value was not used when executing functions/triggers. But when replicating from buggy versions to 5.1.12 or newer, which will use the INSERT_ID value in functions/triggers, the erroneous value will be used, which would cause duplicate entry error and cause the slave to stop. The patch for 5.1 fixed it to ignore the SET INSERT_ID value when executing functions/triggers if it is replicating from a master of buggy versions, another patch for 5.0 fixed it not to generate the erroneous Intvar event. mysql-test/include/show_binlog_events.inc: add $binlog_start parameter to show binlog events from a given position sql/slave.cc: Add function to check for bug#33029 sql/slave.h: Add function to check for bug#33029 sql/sql_class.cc: if master has bug#33029, reset auto_inc_intervals_forced for sub statements add a new function Discrete_intervals_list::append that takes a Discrete_interval as argument sql/sql_class.h: Add member to save and restore auto_inc_intervals_forced sql/structs.h: add copy constructor and assignment operator for Discrete_intervals_list add a new function Discrete_intervals_list::append that takes a Discrete_interval as argument mysql-test/std_data/bug33029-slave-relay-bin.000001: relay logs from a buggy 5.0 master for test case of BUG#33029 mysql-test/suite/binlog/r/binlog_auto_increment_bug33029.result: Test if the slave can process relay logs from a buggy master of BUG#33029 mysql-test/suite/binlog/t/binlog_auto_increment_bug33029-master.opt: Test if the slave can process relay logs from a buggy master of BUG#33029 mysql-test/suite/binlog/t/binlog_auto_increment_bug33029.test: Test if the slave can process relay logs from a buggy master of BUG#33029

Problem: if the IO slave thread is attempting to connect, STOP SLAVE waits for the attempt to finish. It may take a long time. Fix: don't wait, stop the slave immediately. sql/slave.cc: Send a SIGALRM signal to the slave thread when stopping it (using pthread_kill()). This breaks current socket(), connect(), poll() etc. calls, and makes the subsequent thd->awake() call effective. Also, move the definition of KICK_SLAVE to slave.cc. sql/sql_repl.h: Removed KICK_SLAVE and inlined it in slave.cc because: - it was only called once, so better to make it local to where it is used - it needed to include a preprocessor conditional in the middle

log-slave-updates and circul repl Slave SQL thread may execute one extra event when there are events skipped by slave I/O thread (e.g. originated by the same server). Whereas it was requested not to do so by the UNTIL condition. This happens because we compare with the end position of previously executed event. This is fine when there are no skipped by slave I/O thread events, as end position of previous event equals to start position of to be executed event. Otherwise this position equals to start position of skipped event. This is fixed by: - reading the event to be executed before checking if the until condition is satisfied. - comparing the start position of the event to be executed. Since we do not have the start position available, we compute it by subtracting event length from end position (which is available). - if there are no events on the event queue at the slave sql starting time, that meet until condition, we stop immediately, as in this case we do not want to wait for next event. mysql-test/r/rpl_dual_pos_advance.result: A test case for BUG#13861. mysql-test/t/rpl_dual_pos_advance.test: A test case for BUG#13861. sql/log_event.cc: Store length of event.

"Server_IO_State" field Critical error messages from get_master_version_and_clock() were written only to the slave errorlog while Show slave status did not display any incident happened. Although the artifact was reported for a particular --replicate-same-server-id related issue the fix refines all critical error reporting with deploying rli->report(). The test for the bug covers only --replicate-same-server-id error reporting. mysql-test/suite/rpl/r/rpl_server_id1.result: new results reflecting changes mysql-test/suite/rpl/t/rpl_server_id1.test: Preserving the idea of the test unnecessary queries and the sleep are eliminated. In the end the slave must stop with the error displayable via $$$. sql/slave.cc: improving get_master_version_and_clock() code to report a critical incident via rli->report() that takes care of bothe the error log and the slave's status info placeholders. A critical error that force the IO slave thread to terminate is handled immediately (goto err).

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.

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.

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.

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. mysql-test/suite/binlog/std_data/binlog-bug32407.000001: BitKeeper file /home/sven/bk/b32407-5.1-new-rpl-mysqlbinlog_base64/mysql-test/suite/binlog/std_data/binlog-bug32407.000001

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.

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.

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. include/my_base.h: Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE corrupts a MERGE table Added HA_EXTRA_ATTACH_CHILDREN and HA_EXTRA_DETACH_CHILDREN. include/myisammrg.h: Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE corrupts a MERGE table Added element 'children_attached' to MYRG_INFO.

It is now static in sql_parse.cc. Added declaration for fix_merge_after_open(). Renamed open_and_lock_tables() to open_and_lock_tables_derived() with additional parameter 'derived'. Added inline functions simple_open_n_lock_tables() and open_and_lock_tables(), which call open_and_lock_tables_derived() and add the argument for 'derived'. 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 MERGE tables. Added 'thd' argument to init_tmp_table_share(). sql/slave.cc: ug#26379 - Combination of FLUSH TABLE and REPAIR TABLE corrupts a MERGE table Added comment. sql/sql_base.cc: 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 close_handle_and_leave_table_as_lock(), close_thread_tables(), close_thread_table(), unlink_open_table(), reopen_name_locked_table(), reopen_table(), drop_locked_tables(), close_temporary_table(), and open_tables() respectively. Prevented special lock handling of merge children (like mysql_lock_remove, mysql_lock_merge or mysql_lock_abort) at many places. Some of these calls are forwarded to the parent table instead.

Internally it calls simple_open_n_lock_tables() so hat it is appropriate for MERGE tables. Disabled use of open_ltable() for MERGE tables. Removed function simple_open_n_lock_tables(). It is now inline declared in mysql_priv.h. Renamed open_and_lock_tables() to open_and_lock_tables_derived() with additional parameter 'derived'. open_and_lock_tables() is now inline declared in mysql_priv.h.

Changed ha_myisammrg::open() to initialize storage engine structures and create a list of child tables only. Child tables are not opened. Added ha_myisammrg::attach_children(), which does now the main part of MERGE open. Added ha_myisammrg::detach_children().

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. mysql-test/r/partition_hash.result: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Added test result mysql-test/t/partition_hash.test: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Added test sql/event_scheduler.cc: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Initialized lex for later use in open_table(). sql/events.cc: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Initialized lex for later use in open_table(). sql/ha_ndbcluster_binlog.cc: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Initialized lex for later use in open_table(). sql/slave.cc: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Initialized lex for later use in open_table(). sql/sql_acl.cc: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Initialized lex for later use in open_table(). sql/sql_base.cc: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Asserted that lex is initialized in open_table(). sql/sql_connect.cc: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Initialized lex for later use in open_table(). sql/sql_insert.cc: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Added initialization for thd->lex before open table. sql/sql_lex.cc: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Added 'is_lex_started' to test if lex is initialized. sql/sql_lex.h: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Added 'is_lex_started' to test if lex is initialized. sql/sql_plugin.cc: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Initialized lex for later use in open_table(). sql/sql_servers.cc: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Initialized lex for later use in open_table(). sql/sql_udf.cc: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Initialized lex for later use in open_table(). sql/table.cc: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Asserted that lex is initialized in open_table_from_share(). sql/tztime.cc: Bug#31210 - INSERT DELAYED crashes server when used on partitioned table Initialized lex for later use in open_table().

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.

Adding code to keep skipping events while inside a transaction. Execution will start just after the transaction has been skipped. sql/slave.cc: Adding code to set the thd->options flag for the slave SQL thread even when BEGIN, ROLLBACK, COMMIT, and XID events are being skipped. Adding code to not decrease the slave skip counter from 1 to 0 if we are inside a transaction. This will keep the counter at 1, and keep skipping events, until a transaction terminator is read. At that point, the slave skip counter will be decreased to 0, and events will be read and executed instead of read and skipped. mysql-test/r/rpl_slave_skip.result: New BitKeeper file ``mysql-test/r/rpl_slave_skip.result'' mysql-test/t/rpl_slave_skip-slave.opt: New BitKeeper file ``mysql-test/t/rpl_slave_skip-slave.opt'' mysql-test/t/rpl_slave_skip.test: New BitKeeper file ``mysql-test/t/rpl_slave_skip.test''

If a temporary error occured inside a group on an event that was not the first event of the group, the slave could get stuck because the retry counter is reset whenever an event was executed successfully. This patch only reset the retry counter when an entire group has been successfully executed, or failed with a non-transient error. sql/slave.cc: Adding debug printouts to every place where Relay_log_info::trans_retries is changed and to has_temporary_error() to print the error when returning. Adding debug variable all_errors_are_temporary_errors to make all errors for slave thread temporary errors. Adding code so that the Relay_log_info::trans_retries is only reset when an entire group was sucessfully executed, or a non-temporary error occured. mysql-test/suite/rpl/r/rpl_temporary_errors.result: New BitKeeper file ``mysql-test/suite/rpl/r/rpl_temporary_errors.result'' mysql-test/suite/rpl/t/rpl_temporary_errors-slave.opt: New BitKeeper file ``mysql-test/suite/rpl/t/rpl_temporary_errors-slave.opt'' mysql-test/suite/rpl/t/rpl_temporary_errors.test: New BitKeeper file ``mysql-test/suite/rpl/t/rpl_temporary_errors.test''

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. In that case, we should keep going. 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''

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.

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.

Bug#25422 (Hang with log tables) Bug 17876 (Truncating mysql.slow_log in a SP after using cursor locks the thread) Bug 23044 (Warnings on flush of a log table) Bug 29129 (Resetting general_log while the GLOBAL READ LOCK is set causes a deadlock) Prior to this fix, the server would hang when performing concurrent ALTER TABLE or TRUNCATE TABLE statements against the LOG TABLES, which are mysql.general_log and mysql.slow_log. The root cause traces to the following code: in sql_base.cc, open_table() if (table->in_use != thd) { /* wait_for_condition will unlock LOCK_open for us */ wait_for_condition(thd, &LOCK_open, &COND_refresh); } The problem with this code is that the current implementation of the LOGGER creates 'fake' THD objects, like - Log_to_csv_event_handler::general_log_thd - Log_to_csv_event_handler::slow_log_thd which are not associated to a real thread running in the server, so that waiting for these non-existing threads to release table locks cause the dead lock. In general, the design of Log_to_csv_event_handler does not fit into the general architecture of the server, so that the concept of general_log_thd and slow_log_thd has to be abandoned: - this implementation does not work with table locking - it will not work with commands like SHOW PROCESSLIST - having the log tables always opened does not integrate well with DDL operations / FLUSH TABLES / SET GLOBAL READ_ONLY With this patch, the fundamental design of the LOGGER has been changed to: - always open and close a log table when writing a log - remove totally the usage of fake THD objects - clarify how locking of log tables is implemented in general. See WL#3984 for details related to the new locking design. Additional changes (misc bugs exposed and fixed): 1) mysqldump which would ignore some tables in dump_all_tables_in_db(), but forget to ignore the same in dump_all_views_in_db(). 2) mysqldump would also issue an empty "LOCK TABLE" command when all the tables to lock are to be ignored (numrows == 0), instead of not issuing the query. 3) Internal errors handlers could intercept errors but not warnings (see sql_error.cc). 4) Implementing a nested call to open tables, for the performance schema tables, exposed an existing bug in remove_table_from_cache(), which would perform: in_use->some_tables_deleted=1; against another thread, without any consideration about thread locking. This call inside remove_table_from_cache() was not required anyway, since calling mysql_lock_abort() takes care of aborting -- cleanly -- threads that might hold a lock on a table. This line (in_use->some_tables_deleted=1) has been removed. sql/handler.cc: Moved logic for system / log tables in the SQL layer. sql/handler.h: Moved logic for system / log tables in the SQL layer. sql/lock.cc: Revised locking of log tables sql/log.cc: Major cleanup: changed how log tables are locked / written to. sql/log.h: Major cleanup: changed how log tables are locked / written to. sql/mysql_priv.h: performance schema helpers sql/slave.cc: open_ltable() lock flags sql/sp.cc: open_ltable() lock flags sql/sql_acl.cc: open_ltable() lock flags sql/sql_class.h: performance schema helpers sql/sql_delete.cc: log tables cleanup in TRUNCATE sql/sql_error.cc: Internal handlers can also intercept warnings sql/sql_insert.cc: open_ltable() lock flags sql/sql_parse.cc: performance schema helpers sql/sql_plugin.cc: open_ltable() lock flags sql/sql_rename.cc: log tables cleanup in RENAME sql/sql_servers.cc: open_ltable() lock flags sql/sql_show.cc: Move INFORMATION_SCHEMA_NAME to table.cc sql/sql_table.cc: log tables cleanup (admin operations, ALTER TABLE) sql/sql_udf.cc: open_ltable() lock flags sql/table.cc: Implemented TABLE_CATEGORY. sql/share/errmsg.txt: Changed the wording and name of ER_CANT_READ_LOCK_LOG_TABLE sql/table.h: Implemented TABLE_CATEGORY. storage/csv/ha_tina.cc: Moved logic for system / log tables in the SQL layer. storage/csv/ha_tina.h: Moved logic for system / log tables in the SQL layer. storage/myisam/ha_myisam.cc: Moved logic for system / log tables in the SQL layer. storage/myisam/ha_myisam.h: Moved logic for system / log tables in the SQL layer. client/mysqldump.c: Don't lock tables in the ignore list.

Problem: "Under high load, the slave registering to the master can timeout during the COM_REGISTER_SLAVE execution. This causes an error, which prevents the slave from connecting at all." Fix: Do not abort immediately, but retry registering on master. sql/slave.cc: Fix for bug #19328: Slave timeout with COM_REGISTER_SLAVE error causing stop - retry connecting after a failed slave registration on master. Reconnecting has been factored out (see try_to_reconnect() and check_io_slave_killed()) to get rid of similar code used during registering on master/dump requesting/event reading. All messages have been moved to reconnect_messages[] array for easy usage and maintenance. - now one can force slave to reconnect using ./mtr --mysqld=--loose-debug=d,FORCE_SLAVE_TO_RECONNECT_{REG, DUMP, EVENT}

Adding new fields Last_{IO,SQL}_Errno and Last_{IO,SQL}_Error to output of SHOW SLAVE STATUS to hold errors from I/O and SQL thread respectively. Old fields Last_Error and Last_Errno are aliases for Last_SQL_Error and Last_SQL_Errno respectively. Fields are added last to output of SHOW SLAVE STATUS to allow old applications to use the same positional arguments into the row, while allowing new application to benefit from the added information. In addition, some new error codes are added (especially for the I/O thread) to be able to provide sensible error message. mysql-test/extra/rpl_tests/rpl_max_relay_size.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/r/binlog_row_mix_innodb_myisam.result: Result change mysql-test/r/rpl_000015.result: Result change mysql-test/r/rpl_change_master.result: Result change mysql-test/r/rpl_deadlock_innodb.result: Result change mysql-test/r/rpl_empty_master_crash.result: Result change mysql-test/r/rpl_extraCol_innodb.result: Result change --- Result change. mysql-test/r/rpl_extraCol_myisam.result: Result change --- Result change. mysql-test/r/rpl_flushlog_loop.result: Result change mysql-test/r/rpl_loaddata.result: Result change mysql-test/r/rpl_log_pos.result: Result change mysql-test/r/rpl_ndb_basic.result: Result change mysql-test/r/rpl_ndb_extraCol.result: Result change --- Result change. mysql-test/r/rpl_ndb_idempotent.result: Result change mysql-test/r/rpl_ndb_log.result: Result change mysql-test/r/rpl_openssl.result: Result change mysql-test/r/rpl_rbr_to_sbr.result: Result change mysql-test/r/rpl_redirect.result: Result change mysql-test/r/rpl_replicate_do.result: Result change mysql-test/r/rpl_rotate_logs.result: Result change mysql-test/r/rpl_row_inexist_tbl.result: Result change mysql-test/r/rpl_row_log.result: Result change mysql-test/r/rpl_row_log_innodb.result: Result change mysql-test/r/rpl_row_max_relay_size.result: Result change mysql-test/r/rpl_row_reset_slave.result: Result change mysql-test/r/rpl_row_tabledefs_2myisam.result: Result change --- Result change. mysql-test/r/rpl_row_tabledefs_3innodb.result: Result change --- Result change. mysql-test/r/rpl_row_until.result: Result change mysql-test/r/rpl_server_id1.result: Result change mysql-test/r/rpl_server_id2.result: Result change mysql-test/r/rpl_slave_status.result: Result change mysql-test/r/rpl_stm_log.result: Result change mysql-test/r/rpl_stm_max_relay_size.result: Result change --- Result change. mysql-test/r/rpl_stm_reset_slave.result: Result change mysql-test/r/rpl_stm_until.result: Result change mysql-test/t/binlog_row_mix_innodb_myisam.test: Test fixed. mysql-test/t/rpl_000015.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_change_master.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_empty_master_crash.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_flushlog_loop.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_log_pos.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_ndb_bank.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_ndb_basic.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_ndb_idempotent.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_ndb_sync.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_openssl.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_rbr_to_sbr.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_redirect.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_replicate_do.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_rotate_logs.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_row_inexist_tbl.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_row_until.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_server_id1.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_server_id2.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_slave_status.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno mysql-test/t/rpl_stm_until.test: Commenting out irrelevant fields Last_IO_Error and Last_IO_Errno sql/Makefile.am: Adding new files sql/log_event.cc: Changes to use Slave_reporting_capability for reporting errors.
