BUG#11745230: 12133: MASTER.INDEX FILE KEEPS MYSQLD FROM STARTING IF
BIN LOG HAS BEEN MOVED
When moving the binary/relay log files from one location to
another and restarting the server with a different log-bin or
relay-log paths, would cause the startup process to abort. The
root cause was that the server would not be able to find the log
files because it would consider old paths for entries in the
index file instead of the new location. What's even worse, the
relative paths would not be considered relative to the path
provided in log-bin and relay-log, but to mysql_data_dir.
We fix the cases where the server contains relative paths. When
the server is reading from the index file, it checks whether the
entry contains relative paths. If it does, we replace it with the
absolute path set in log-bin/relay-log option. Absolute paths
remain unchanged and the index must be manually edited to
consider the new log-bin and/or relay-log path (this should be
documented). This is a fix for a GA version, that does not break
behavior (that much).
For development versions, we should go with Zhenxing's approach
that removes paths altogether from index files.
mysql-test/include/begin_include_file.inc:
Added parameter to keep the begin_include_file.inc silent. Useful when
including scripts that contain platform dependent parameters, for example:
--let $rpl_server_parameters=--log-bin=$tmpdir/slave-bin --relay-log=$tmpdir/slave-relay-bin
--let $keep_include_silent=1
source include/rpl_start_server.inc;
--let $keep_include_silent=0
We want the paths ($tmpdir/slave-bin and $tmpdir/slave-relay-bin) not to be in the
result file.
mysql-test/suite/rpl/t/rpl_binlog_index.test:
Test case.
sql/log.cc:
When finding the corresponding log entry in the index file, we first
normalize the paths before doing the comparison. This will make relative
paths to be turned into absolute paths (based on the opt_bin_logname or
opt_relay_logname) and then compared against also, expanded paths entered,
through CHANGE MASTER for instance.
sql/log.h:
Added normalize_binlog_name, which turns relative paths, into absolute paths
given the parameter: is_relay_log ? opt_relay_logname : opt_bin_logname .
sql/mysqld.cc:
Exposing opt_bin_logname.
sql/mysqld.h:
Exposing opt_bin_logname.

Fixes for parallel slave:
- Made slaves temporary table multi-thread slave safe by adding mutex around save_temporary_table usage.
- rli->save_temporary_tables is the active list of all used temporary tables
- This is copied to THD->temporary_tables when temporary tables are opened and updated when temporary tables are closed
- Added THD->lock_temporary_tables() and THD->unlock_temporary_tables() to simplify this.
- Relay_log_info->sql_thd renamed to Relay_log_info->sql_driver_thd to avoid wrong usage for merged code.
- Added is_part_of_group() to mark functions that are part of the next function. This replaces setting IN_STMT when events are executed.
- Added is_begin(), is_commit() and is_rollback() functions to Query_log_event to simplify code.
- If slave_skip_counter is set run things in single threaded mode. This simplifies code for skipping events.
- Updating state of relay log (IN_STMT and IN_TRANSACTION) is moved to one single function: update_state_of_relay_log()
We can't use OPTION_BEGIN to check for the state anymore as the sql_driver and sql execution threads may be different.
Clear IN_STMT and IN_TRANSACTION in init_relay_log_pos() and Relay_log_info::cleanup_context() to ensure the flags doesn't survive slave restarts
is_in_group() is now independent of state of executed transaction.
- Reset thd->transaction.all.modified_non_trans_table() if we did set it for single table row events.
This was mainly for keeping the flag as documented.
- Changed slave_open_temp_tables to uint32 to be able to use atomic operators on it.
- Relay_log_info::sleep_lock -> rpl_group_info::sleep_lock
- Relay_log_info::sleep_cond -> rpl_group_info::sleep_cond
- Changed some functions to take rpl_group_info instead of Relay_log_info to make them multi-slave safe and to simplify usage
- do_shall_skip()
- continue_group()
- sql_slave_killed()
- next_event()
- Simplifed arguments to io_salve_killed(), check_io_slave_killed() and sql_slave_killed(); No reason to supply THD as this is part of the given structure.
- set_thd_in_use_temporary_tables() removed as in_use is set on usage
- Added information to thd_proc_info() which thread is waiting for slave mutex to exit.
- In open_table() reuse code from find_temporary_table()
Other things:
- More DBUG statements
- Fixed the rpl_incident.test can be run with --debug
- More comments
- Disabled not used function rpl_connect_master()

Removed IN_STMT flag setting. This is now done in update_state_of_relay_log()
Use IN_TRANSACTION flag to test state of relay log.
In rows_event_stmt_cleanup() reset thd->transaction.all.modified_non_trans_table if we had set this before.
sql/log_event.h:
do_shall_skip(), continue_group() now takes rpl_group_info param
Added is_part_of_group() to mark events that are part of the next event. This replaces setting IN_STMT when events are executed.

Reset table->in_use for temporary tables as the table may have been used by another THD.
Use IN_TRANSACTION instead of OPTION_BEGIN to check state of relay log.
Removed IN_STMT flag setting. This is now done in update_state_of_relay_log()
sql/rpl_rli.h:
Changed relay log state flags to bit masks instead of bit positions (most other code we have uses bit masks)
Added IN_TRANSACTION to mark if we are in a BEGIN ... COMMIT section.
save_temporary_tables is now thread safe
Relay_log_info::sleep_lock -> rpl_group_info::sleep_lock
Relay_log_info::sleep_cond -> rpl_group_info::sleep_cond

If slave_skip_counter is set run things in single threaded mode.
Simplifed arguments to io_salve_killed(), check_io_slave_killed() and sql_slave_killed(); No reason to supply THD as this is part of the given structure.
Added information to thd_proc_info() which thread is waiting for slave mutex to exit.
Disabled not used function rpl_connect_master()
Updated argument to next_event()

Fixes for parallel slave:
- Made slaves temporary table multi-thread slave safe by adding mutex around save_temporary_table usage.
- rli->save_temporary_tables is the active list of all used temporary tables
- This is copied to THD->temporary_tables when temporary tables are opened and updated when temporary tables are closed
- Added THD->lock_temporary_tables() and THD->unlock_temporary_tables() to simplify this.
- Relay_log_info->sql_thd renamed to Relay_log_info->sql_driver_thd to avoid wrong usage for merged code.
- Added is_part_of_group() to mark functions that are part of the next function. This replaces setting IN_STMT when events are executed.
- Added is_begin(), is_commit() and is_rollback() functions to Query_log_event to simplify code.
- If slave_skip_counter is set run things in single threaded mode. This simplifies code for skipping events.
- Updating state of relay log (IN_STMT and IN_TRANSACTION) is moved to one single function: update_state_of_relay_log()
We can't use OPTION_BEGIN to check for the state anymore as the sql_driver and sql execution threads may be different.
Clear IN_STMT and IN_TRANSACTION in init_relay_log_pos() and Relay_log_info::cleanup_context() to ensure the flags doesn't survive slave restarts
is_in_group() is now independent of state of executed transaction.
- Reset thd->transaction.all.modified_non_trans_table() if we did set it for single table row events.
This was mainly for keeping the flag as documented.
- Changed slave_open_temp_tables to uint32 to be able to use atomic operators on it.
- Relay_log_info::sleep_lock -> rpl_group_info::sleep_lock
- Relay_log_info::sleep_cond -> rpl_group_info::sleep_cond
- Changed some functions to take rpl_group_info instead of Relay_log_info to make them multi-slave safe and to simplify usage
- do_shall_skip()
- continue_group()
- sql_slave_killed()
- next_event()
- Simplifed arguments to io_salve_killed(), check_io_slave_killed() and sql_slave_killed(); No reason to supply THD as this is part of the given structure.
- set_thd_in_use_temporary_tables() removed as in_use is set on usage
- Added information to thd_proc_info() which thread is waiting for slave mutex to exit.
- In open_table() reuse code from find_temporary_table()
Other things:
- More DBUG statements
- Fixed the rpl_incident.test can be run with --debug
- More comments
- Disabled not used function rpl_connect_master()

sql/log_event.cc:
Added DBUG statements
do_shall_skip(), continue_group() now takes rpl_group_info param
Use is_begin(), is_commit() and is_rollback() functions instead of inspecting query string
We don't have set slaves temporary tables 'in_use' as this is now done when tables are opened.
Removed IN_STMT flag setting. This is now done in update_state_of_relay_log()
Use IN_TRANSACTION flag to test state of relay log.
In rows_event_stmt_cleanup() reset thd->transaction.all.modified_non_trans_table if we had set this before.
sql/log_event.h:
do_shall_skip(), continue_group() now takes rpl_group_info param
Added is_part_of_group() to mark events that are part of the next event. This replaces setting IN_STMT when events are executed.
Added is_begin(), is_commit() and is_rollback() functions to Query_log_event to simplify code.

sql/log_event_old.h:
Added is_part_of_group() to mark events that are part of the next event.
do_shall_skip(), continue_group() now takes rpl_group_info param
sql/mysqld.cc:

sql_thd -> sql_driver_thd
Relay_log_info::sleep_lock -> rpl_group_info::sleep_lock
Relay_log_info::sleep_cond -> rpl_group_info::sleep_cond
Clear IN_STMT and IN_TRANSACTION in init_relay_log_pos() and Relay_log_info::cleanup_context() to ensure the flags doesn't survive slave restarts.
Reset table->in_use for temporary tables as the table may have been used by another THD.
Use IN_TRANSACTION instead of OPTION_BEGIN to check state of relay log.
Removed IN_STMT flag setting. This is now done in update_state_of_relay_log()
sql/rpl_rli.h:
Changed relay log state flags to bit masks instead of bit positions (most other code we have uses bit masks)
Added IN_TRANSACTION to mark if we are in a BEGIN ... COMMIT section.
save_temporary_tables is now thread safe
Relay_log_info::sleep_lock -> rpl_group_info::sleep_lock
Relay_log_info::sleep_cond -> rpl_group_info::sleep_cond
Relay_log_info->sql_thd renamed to Relay_log_info->sql_driver_thd to avoid wrong usage for merged code
is_in_group() is now independent of state of executed transaction.

Simplifed arguments to io_salve_killed(), sql_slave_killed() and check_io_slave_killed(); No reason to supply THD as this is part of the given structure.
set_thd_in_use_temporary_tables() removed as in_use is set on usage in sql_base.cc
sql_thd -> sql_driver_thd
More DBUG
Added update_state_of_relay_log() which will calculate the IN_STMT and IN_TRANSACTION state of the relay log after the current element is executed.
If slave_skip_counter is set run things in single threaded mode.
Simplifed arguments to io_salve_killed(), check_io_slave_killed() and sql_slave_killed(); No reason to supply THD as this is part of the given structure.
Added information to thd_proc_info() which thread is waiting for slave mutex to exit.
Disabled not used function rpl_connect_master()
Updated argument to next_event()
sql/sql_base.cc:
Added mutex around usage of slave's temporary tables. The active list is always kept up to date in sql->rgi_slave->save_temporary_tables.
Clear thd->temporary_tables after query (safety)
More DBUG
When using temporary table, set table->in_use to current thd as the THD may be different for slave threads.
Some code is ifdef:ed with REMOVE_AFTER_MERGE_WITH_10 as the given code in 10.0 is not yet in this tree.
In open_table() reuse code from find_temporary_table()
sql/sql_binlog.cc:
rli->sql_thd -> rli->sql_driver_thd
Remove duplicate setting of rgi->rli
sql/sql_class.cc:
Added helper functions rgi_lock_temporary_tables() and rgi_unlock_temporary_tables()
Would have been nicer to have these inline, but there was no easy way to do that
sql/sql_class.h:
Added functions to protect slaves temporary tables
sql/sql_parse.cc:
Added DBUG_PRINT
sql/transaction.cc:

- Added information to thd_proc_info() which thread is waiting for slave mutex to exit.
- In open_table() reuse code from find_temporary_table()
Other things:
- More DBUG statements
- Fixed the rpl_incident.test can be run with --debug
- More comments
- Disabled not used function rpl_connect_master()
mysql-test/suite/perfschema/r/all_instances.result:
Moved sleep_lock and sleep_cond to rpl_group_info
mysql-test/suite/rpl/r/rpl_incident.result:
Updated result
mysql-test/suite/rpl/t/rpl_incident-master.opt:
Not needed anymore
mysql-test/suite/rpl/t/rpl_incident.test:
Fixed that test can be run with --debug
sql/handler.cc:
More DBUG_PRINT
sql/log.cc:
More comments
sql/log_event.cc:
Added DBUG statements
do_shall_skip(), continue_group() now takes rpl_group_info param
Use is_begin(), is_commit() and is_rollback() functions instead of inspecting query string
We don't have set slaves temporary tables 'in_use' as this is now done when tables are opened.
Removed IN_STMT flag setting. This is now done in update_state_of_relay_log()
Use IN_TRANSACTION flag to test state of relay log.
In rows_event_stmt_cleanup() reset thd->transaction.all.modified_non_trans_table if we had set this before.
sql/log_event.h:
do_shall_skip(), continue_group() now takes rpl_group_info param
Added is_part_of_group() to mark events that are part of the next event. This replaces setting IN_STMT when events are executed.
Added is_begin(), is_commit() and is_rollback() functions to Query_log_event to simplify code.
sql/log_event_old.cc:
Removed IN_STMT flag setting. This is now done in update_state_of_relay_log()
do_shall_skip(), continue_group() now takes rpl_group_info param
sql/log_event_old.h:
Added is_part_of_group() to mark events that are part of the next event.
do_shall_skip(), continue_group() now takes rpl_group_info param
sql/mysqld.cc:
Changed slave_open_temp_tables to uint32 to be able to use atomic operators on it.
Relay_log_info::sleep_lock -> Rpl_group_info::sleep_lock
Relay_log_info::sleep_cond -> Rpl_group_info::sleep_cond
sql/mysqld.h:
Updated types and names
sql/rpl_gtid.cc:
More DBUG
sql/rpl_parallel.cc:
Updated TODO section
Set thd for event that is execution
Use new is_begin(), is_commit() and is_rollback() functions.
More comments
sql/rpl_rli.cc:
sql_thd -> sql_driver_thd
Relay_log_info::sleep_lock -> rpl_group_info::sleep_lock
Relay_log_info::sleep_cond -> rpl_group_info::sleep_cond
Clear IN_STMT and IN_TRANSACTION in init_relay_log_pos() and Relay_log_info::cleanup_context() to ensure the flags doesn't survive slave restarts.
Reset table->in_use for temporary tables as the table may have been used by another THD.
Use IN_TRANSACTION instead of OPTION_BEGIN to check state of relay log.
Removed IN_STMT flag setting. This is now done in update_state_of_relay_log()
sql/rpl_rli.h:
Changed relay log state flags to bit masks instead of bit positions (most other code we have uses bit masks)
Added IN_TRANSACTION to mark if we are in a BEGIN ... COMMIT section.
save_temporary_tables is now thread safe
Relay_log_info::sleep_lock -> rpl_group_info::sleep_lock
Relay_log_info::sleep_cond -> rpl_group_info::sleep_cond
Relay_log_info->sql_thd renamed to Relay_log_info->sql_driver_thd to avoid wrong usage for merged code
is_in_group() is now independent of state of executed transaction.
sql/slave.cc:
Simplifed arguments to io_salve_killed(), sql_slave_killed() and check_io_slave_killed(); No reason to supply THD as this is part of the given structure.
set_thd_in_use_temporary_tables() removed as in_use is set on usage in sql_base.cc
sql_thd -> sql_driver_thd
More DBUG
Added update_state_of_relay_log() which will calculate the IN_STMT and IN_TRANSACTION state of the relay log after the current element is executed.
If slave_skip_counter is set run things in single threaded mode.
Simplifed arguments to io_salve_killed(), check_io_slave_killed() and sql_slave_killed(); No reason to supply THD as this is part of the given structure.
Added information to thd_proc_info() which thread is waiting for slave mutex to exit.
Disabled not used function rpl_connect_master()
Updated argument to next_event()
sql/sql_base.cc:
Added mutex around usage of slave's temporary tables. The active list is always kept up to date in sql->rgi_slave->save_temporary_tables.
Clear thd->temporary_tables after query (safety)
More DBUG
When using temporary table, set table->in_use to current thd as the THD may be different for slave threads.
Some code is ifdef:ed with REMOVE_AFTER_MERGE_WITH_10 as the given code in 10.0 is not yet in this tree.
In open_table() reuse code from find_temporary_table()
sql/sql_binlog.cc:
rli->sql_thd -> rli->sql_driver_thd
Remove duplicate setting of rgi->rli
sql/sql_class.cc:
Added helper functions rgi_lock_temporary_tables() and rgi_unlock_temporary_tables()
Would have been nicer to have these inline, but there was no easy way to do that
sql/sql_class.h:
Added functions to protect slaves temporary tables
sql/sql_parse.cc:
Added DBUG_PRINT
sql/transaction.cc:

fixes for test failures
and small collateral changes
mysql-test/lib/My/Test.pm:
somehow with "print" we get truncated writes sometimes
mysql-test/suite/perfschema/r/digest_table_full.result:
md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/perfschema/r/dml_handler.result:
host table is not ported over yet
mysql-test/suite/perfschema/r/information_schema.result:
host table is not ported over yet
mysql-test/suite/perfschema/r/nesting.result:
this differs, because we don't rewrite general log queries, and multi-statement
packets are logged as a one entry. this result file is identical to what mysql-5.6.5
produces with the --log-raw option.
mysql-test/suite/perfschema/r/relaylog.result:
MariaDB modifies the binlog index file directly, while MySQL 5.6 has a feature "crash-safe binlog index" and modifies a special "crash-safe" shadow copy of the index file and then moves it over. That's why this test shows "NONE" index file writes in MySQL and "MANY" in MariaDB.
mysql-test/suite/perfschema/r/server_init.result:
MariaDB initializes the "manager" resources from the "manager" thread, and starts this thread only when --flush-time is not 0. MySQL 5.6 initializes "manager" resources unconditionally on server startup.
mysql-test/suite/perfschema/r/stage_mdl_global.result:
this differs, because MariaDB disables query cache when query_cache_size=0. MySQL does not
do that, and this causes useless mutex locks and waits.
mysql-test/suite/perfschema/r/statement_digest.result:
md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/perfschema/r/statement_digest_consumers.result:
md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/perfschema/r/statement_digest_long_query.result:
md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/rpl/r/rpl_mixed_drop_create_temp_table.result:
