Bug #55755 : Date STD variable signness breaks server on FreeBSD and OpenBSD
* Added a check to configure on the size of time_t
* Created a macro to check for a valid time_t that is safe to use with datetime
functions and store in TIMESTAMP columns.
* Used the macro consistently instead of the ad-hoc checks introduced by 52315
* Fixed compliation warnings on platforms where the size of time_t is smaller than
the size of a long (e.g. OpenBSD 4.8 64 amd64).
Bug #52315: utc_date() crashes when system time > year 2037
* Added a correct check for the timestamp range instead of just variable size check to
SET TIMESTAMP.
* Added overflow checking before converting to time_t.
* Using a correct localized error message in this case instead of the generic error.
* Added a test suite.
* fixed the checks so that they check for unsigned time_t as well. Used the checks
consistently across the source code.
* fixed the original test case to expect the new error code.
- MWL#47, allowing to annotate row-based binlog events with the SQL test of
the originating query (eg. in mysqlbinlog output).
- row_based_replication_without_primary_key.patch, providing more intelligent
selection of index to use on slave when applying row-based binlog events
for tables with no primary key.
- Make mysqlbinlog omit redundant `use` around BEGIN/SAVEPOINT/COMMIT/
ROLLBACK in 5.0 binlogs.
This patch adds options to annotate the binlog (and the mysqlbinlog
output) with the original SQL query for queries that are logged
using row-based replication.
After fix of bug#25192, load_defaults() will add an args separator
to distinguish options loaded from configure files from that provided
in the command line. One problem of this is that the args separator
would be added no matter the application need it or not.
Fixed the problem by adding an option:
bool my_getopt_use_args_separator;
to control whether the separator will be added or not. And also
added functions:
bool my_getopt_is_args_separator(const char* arg);
to check if the argument is the separator or not.
mysql-test/r/mysqld--help-notwin.result:
consequence of introducing opt_autocommit and its default
mysql-test/suite/sys_vars/r/autocommit_func4.result:
Before this fix, this test would have shown @@global.autocommit == 0
in spite of --autocommit=on.
mysql-test/suite/sys_vars/r/autocommit_func5.result:
result unchanged by the fix
sql/mysqld.cc:
atoi(argument) was reliable for =0|1 parameters. Now that boolean options
must support =on/off/true/false, atoi(argument) is wrong (being always 0
for those strings). Instead, let the internal logic of my_getopt
(in particular get_bool_argument()) set a boolean opt_autocommit
properly, and use that to set global_system_variables.option_bits.

It includes speed optimizations for HANDLER READ by caching as much as possible in HANDLER OPEN
Other things:
- Added mysqld option --disable-thr-alarm to be able to benchmark things without thr_alarm
- Changed 'Locked' state to 'System lock' and 'Table lock' (these where used in the code but never shown to end user)

- Remove not anymore used 'thd->locked' member
include/thr_alarm.h:
Added my_disable_thr_alarm
include/thr_lock.h:
Add new member to THR_LOCK_DATA to remember original lock type state. This is needed as thr_unlock() resets type to TL_UNLOCK.

The problem is a race between a session closing its vio
(i.e. after a COM_QUIT) at the same time it is being killed by
another thread. This could trigger a assertion in vio_close()
as the two threads could end up closing the same vio, at the
same time. This could happen due to the implementation of
SIGNAL_WITH_VIO_CLOSE, which closes the vio of the thread
being killed.
The solution is to serialize the close of the Vio under
LOCK_thd_data, which protects THD data.
No regression test is added as this is essentially a debug
issue and the test case would be quite convoluted as we would
need to synchronize a session that is being killed -- which
is a bit difficult since debug sync points code does not
synchronize killed sessions.
sql/mysqld.cc:
Drop lock parameter from close_connection, its not necessary
any more. The newly introduced THD::disconnect method will take
care of locking.
sql/mysqld.h:
Change prototype, add a default parameter for the error code.
sql/sql_class.cc:
In case SIGNAL_WITH_VIO_CLOSE is defined, the active vio is
closed and cleared. Subsequent calls will only close the vio
owned by the session.

- Fixed problem with oqgraph and 'make dist'
Note that after this merge we have a problem show in join_outer where we examine too many rows in one specific case (related to BUG#57024).
This will be fixed when mwl#128 is merged into 5.3.
when generating new name.
If find_uniq_filename returns an error, then this error is not
being propagated upwards, and execution does not report error to
the user (although a entry in the error log is generated).
Additionally, some more errors were ignored in new_file_impl:
- when writing the rotate event
- when reopening the index and binary log file
This patch addresses this by propagating the error up in the
execution stack. Furthermore, when rotation of the binary log
fails, an incident event is written, because there may be a
chance that some changes for a given statement, were not properly
logged. For example, in SBR, LOAD DATA INFILE statement requires
more than one event to be logged, should rotation fail while
logging part of the LOAD DATA events, then the logged data would
become inconsistent with the data in the storage engine.
mysql-test/include/restart_mysqld.inc:
Refactored restart_mysqld so that it is not hardcoded for
mysqld.1, but rather for the current server.
mysql-test/suite/binlog/t/binlog_index.test:
The error on open of index and binary log on new_file_impl
is now caught. Thence the user will get an error message.
We need to accomodate this change in the test case for the
failing FLUSH LOGS.
mysql-test/suite/rpl/t/rpl_binlog_errors-master.opt:
Sets max_binlog_size to 4096.
mysql-test/suite/rpl/t/rpl_binlog_errors.test:
Added some test cases for asserting that the error is found
and reported.
sql/handler.cc:
Catching error now returned by unlog (in ha_commit_trans) and
returning it.
sql/log.cc:
Propagating errors from new_file_impl upwards. The errors that
new_file_impl catches now are:
- error on generate_new_name
- error on writing the rotate event
- error when opening the index or the binary log file.
sql/log.h:
Changing declaration of:
- rotate_and_purge
- new_file
- new_file_without_locking
- new_file_impl
- unlog
They now return int instead of void.
sql/mysql_priv.h:
Change signature of reload_acl_and_cache so that write_to_binlog
is an int instead of bool.
sql/mysqld.cc:
Redeclaring not_used var as int instead of bool.
sql/rpl_injector.cc:
Changes to catch the return from rotate_and_purge.
sql/slave.cc:
Changes to catch the return values for new_file and rotate_relay_log.
sql/slave.h:
Changes to rotate_relay_log declaration (now returns int
instead of void).
sql/sql_load.cc:
In SBR, some logging of LOAD DATA events goes through
IO_CACHE_CALLBACK invocation at mf_iocache.c:_my_b_get. The
IO_CACHE implementation is ignoring the return value for from
these callbacks (pre_read and post_read), so we need to find out
at the end of the execution if the error is set or not in THD.
sql/sql_parse.cc:
Catching the rotate_relay_log and rotate_and_purge return values.
Semantic change in reload_acl_and_cache so that we report errors
in binlog interactions through the write_to_binlog output parameter.
If there was any failure while rotating the binary log, we should
then report the error to the client when handling SQLCOMM_FLUSH.

sql/multi_range_read.cc:
Fixed compiler warning by using correct type for function argument
sql/mysqld.cc:
Changed rows_read and rows_sent status variables to be longlong
sql/opt_subselect.h:
Fixed compiler warning by using correct type for function argument
sql/sql_class.cc:
Changed rows_read and rows_sent status variables to be longlong
sql/sql_class.h:
Changed rows_read and rows_sent status variables to be longlong
Changed max_nulls_in_row to uint as this is number of columns in row.
This fixed some compiler warnings.
sql/sql_select.cc:
Added casts to avoid compiler warnings
storage/heap/ha_heap.cc:
Initilize different types separate
storage/oqgraph/ha_oqgraph.cc:
Fixed argument to store(longlong) to avoid compiler warnings
The problem is that the logic which checks if a pointer is
valid relies on a poor heuristic based on the start and end
addresses of the data segment and heap.
Apart from miscalculating the heap bounds, this approach also
suffers from the fact that memory can come from places other
than the heap. See Bug#58528 for a more detailed explanation.
On Linux, the solution is to access the process's memory
through /proc/self/task/<tid>/mem, which allows for retrieving
the contents of pages within the virtual address space of
the calling process. If a address range is not mapped, a
input/output error is returned.
client/mysqltest.cc:
Use new interface to my_safe_print_str.
include/my_stacktrace.h:
Drop name from my_safe_print_str.
mysys/stacktrace.c:
Access the process's memory through a file descriptor and
dump the contents of the memory range. The file descriptor
offset is equivalent to a offset into the address space.
Do not print the name of the variable associated with the
address. It can be better accomplished at a higher level.
sql/mysqld.cc:
Put the variable dumping information within its own newline block.
Use symbolic names which better convey information to the user.
