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.

gettimeofday() can fail and presumably, so can time().
Keep an eye on it.
Since we have no data on this at all so far, we just
retry on failure (and log the event), assuming that
this is just an intermittant failure. This might of
course hang the threat until we succeed. Once we know
more about these failures, an appropriate more clever
scheme may be picked (only try so many times per thread,
etc., if that fails, return last "good" time() we got or
some such). Using sql_print_information() to log as this
probably only occurs in high load scenarios where the debug-
trace likely is disabled (or might interfere with testing
the effect). No test-case as this is a non-deterministic
issue.

By default MyISAM overwrites .MYD and .MYI files no
DATA DIRECTORY option is used. This can lead to two tables
using the same .MYD and .MYI files (that can't be dropped).
To prevent CREATE TABLE from overwriting a file a new option
is introduced : keep_files_on_create
When this is on the CREATE TABLE throws an error if either
the .MYD or .MYI exists for a MyISAM table.
The option is off by default (resulting in compatible behavior).

Add more accessors to MySQL internals in mysql/plugin.h, for storage
engine plugins.
Add some accessors specific to the InnoDB storage engine, to allow
InnoDB to be compiled as a plugin (without MYSQL_SERVER). InnoDB
has additional requirements, due to its foreign key support, etc.
include/m_string.h:
Add structure tag to LEX_STRING definition, so that it can be referred
to by forward declarations. Allow struct st_mysql_lex_string to be
defined here, or in mysql/plugin.h.
include/my_global.h:
Define INNODB_COMPATIBILITY_HOOKS unconditionally; it brackets
some definitions needed for the InnoDB storage engine plugin
which do not belong in our general plugin interface.
include/mysql/plugin.h:
Additional accessors for MySQL internals:
- Full definition of MYSQL_LEX_STRING (identical to LEX_STRING from
m_string.h)
- Full definition of MYSQL_XID (binary compatible with XID from
handler.h)
- mysql_tmpfile(), creates a temporary file in mysqld's tmpdir
- thd_killed(), to check killed state of connection
- thd_alloc() and similar allocation functions
- thd_get_xid(), to get XID of connection's transaction
- mysql_query_cache_invalidate4, to invalidate a table's query cache entries
sql/handler.h:
Use MYSQL_XIDDATASIZE definition from mysql/plugin.h, to avoid redundant
definitions
sql/log.cc:
Add definitions for two InnoDB compatibility hooks:
- mysql_bin_log_file(), to get log filename
- mysql_bin_log_file_pos, to get position in file
These are defined only if INNODB_COMPATIBILITY_HOOKS is defined;
they are needed by the InnoDB plugin, but aren't part of the general
plugin interface. They are declared in ha_innodb.h for InnoDB's
use.
sql/mysql_priv.h:
Expose some server internals when INNODB_COMPATIBILITY_HOOKS is
defined, so that InnoDB can be built as a plugin when MYSQL_SERVER
is not defined.
Move make_lex_string inside THD class.
sql/sql_cache.cc:
Add definiton of mysql_query_cache_invalidate4(), a part of the
plugin API (mysql/plugin.h).
sql/sql_class.cc:
Add definitions for several accessor functions which form part
of the plugin API (mysql/plugin.h):
- mysql_tmpfile()
- thd_alloc() and friends
- thd_make_lex_string()
- thd_get_xid()
Add definitons for accessor functions which InnoDB requires,
but which are not part of the plugin interface:
- thd_charset()
- thd_query()
- thd_slave_thread()
- thd_non_transactional_update()
- thd_binlog_format()
Move definition of make_lex_string() from sql_show.cc into THD class
sql/sql_class.h:
Remove LEX_STRING_make(), and move make_lex_string() from sql_show.cc inside THD
class.
sql/sql_parse.cc:
Use thd->make_lex_string() instead of thd->LEX_STRING_make()
sql/sql_show.cc:
Move make_lex_string() inside THD class
storage/innobase/handler/ha_innodb.cc:
Call thd_make_lex_string() instead of make_lex_string().
