but the statement is written to binlog
TRUNCATE PARTITION was written to the binlog
even if it failed before calling any partition's
truncate function.
Solved by adding an argument to truncate_partition,
to flag if it should be written to the binlog or not.
It should be written to the binlog when a call to any
partitions truncate function is done.

When installing plugins, there is a missing check
for slash (/) in the path on Windows. Note that on
Windows, both / and \ can be used to separate
directories.
This patch fixes the issue by:
- Adding a FN_DIRSEP symbol for all platforms
consisting of a string of legal directory
separators.
- Adding a charset-aware version of strcspn().
- Adding a check_valid_path() function that uses
my_strcspn() to check if any FN_DIRSEP character
is in the supplied string.
- Using the check_valid_path() function in
sql_plugin.cc and sql_udf.cc (which means
replacing the existing test there).

This is a code cleanup.
The implementation of a storage engine (subclasses of handler) is not supposed
to call my_error() directly inside the engine implementation,
but only return error codes, and report errors later at the demand
of the sql layer only (if needed), using handler::print_error().
This fix removes misplaced calls to my_error(),
and provide an implementation of print_error() instead.
Given that the sql layer implementation of create table, ha_create_table(),
does not use print_error() but returns ER_CANT_CREATE_TABLE directly,
the return code for create table statements using the performance schema
has changed to ER_CANT_CREATE_TABLE.
Adjusted the test suite accordingly.
Before this fix, the test thread_cache failed with spurious failures.
The test used:
-- disconnect X
-- connect Y
while assuming that connection Y would reuse connection X slot in the thread cache.
For this to happen, the disconnect X operation must be given enough time to complete,
otherwise connect Y can be executed in the server before X actually finishes.
This fix uses wait conditions to make the test execution more controlled,
and more reproductible.
Before this fix, the test myisam_file_io executed:
- (a) an update on setup_instrument to disable non myisam file io instruments
- (b) a truncate on events_waits_history_long
and later
- (c) a select on events_waits_history_long
Surprisingly, events that were supposed to be disabled in (a) and removed in (b)
still were found in (c).
This happened for events such as
wait/io/file/innodb/innodb_data_file fil0fil.c: sync
because the sync was started before (a) and completed after (b),
and as a consequence was added in the performance schema history, as expected.
Presence of these records in the history made the test fail.
This fix makes the test script more robust to account for extra spill waits records in (c).
This fix affects the test suite only.
Before this fix, performance schema tests dml_*.test could
fail with spurious failure, depending on the table content.
This fix simplifies the SELECT tests in the dml_*.test scripts,
to only verify that the SELECT operation passed the security checks
and succeeded, which was the original intent of the test.
Usage of
--replace_column 1 # 2 # 3 # 4 # ...
to discard the test output was replaced by a simpler and more maintainable
--disable_result_log
which also work for empty tables.
Fixing the testcase to use the database name
as connected_db instead of 'test' database.

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.

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.
The problem was due to a misuse of GCC asm constraints used to
implement a atomic load. On x86_64, the load was implemented
as a cmpxchg which implicitly uses the eax register as a
source and destination operand, yet the dummy value used for
comparison wasn't being properly loaded into eax (and other
problems).
The core problem is that cmpxchg is unnecessary as a load
on x86_64 as there are other simpler instructions such
as xadd. Even though, such instructions are only used to
have a memory barrier as load and stores are atomic by
definition. Hence, the solution is to explicitly issue the
required CPU and compiler barriers.

Issue a synchronizing instruction before loading the value.
Afterwards, issue a compiler barrier to prevent reordering.

and pass it to off_t.

The problem was that mysql_upgrade failed because DROP DATABASE
refused to drop the 'performance_schema' database when the
mysql.proc table definition was made temporarily invalid
by dump import.
This patch fixes the problem by adding the error resulting
from opening a damaged mysq.proc table (ER_CANNOT_LOAD_FROM_TABLE),
to the list of errors DROP DATABASE will ignore when trying
to lock stored procedures and functions before deletion.
This problem was a regression introduced by the patch for
Bug#57663.
Test case added to sp-destruct.test.

the DROP statement ..."
Problem: When using temporary tables and closing a session, an
implicit DROP TEMPORARY TABLE IF EXISTS is written to the binary
log (while cleaning up the context of the session THD - see:
sql_class.cc:THD::cleanup which calls close_temporary_tables).
close_temporary_tables, first checks if the binary log is opened
and then proceeds to creating the DROP statements. Then, such
statements, are written to the binary log through
MYSQL_BIN_LOG::write(Log_event *). Inside, there is another check
if the binary log is opened and if not an error is returned. This
is where the faulty behavior is triggered. Given that the test
case replays a binary log, with temp tables statements, and right
after it issues RESET MASTER, there is a chance that is_open will
report false (when the mysql session is closed and the temporary
tables are written).
is_open may return false, because MYSQL_BIN_LOG::reset_logs is
not setting the correct flag (LOG_CLOSE_TO_BE_OPENED), on the
MYSQL_LOG_BIN::log_state (instead it sets just the
LOG_CLOSE_INDEX flag, leaving the log_state to
LOG_CLOSED). Thence, when writing the DROP statement as part of
the THD::cleanup, the thread could get a return value of false
for is_open - inside MYSQL_BIN_LOG::write, ultimately reporting
that it can't write the event to the binary log.
Fix: We fix this by adding the correct flag, missing in the
second close.
InnoDB AUTOINC code expects the locks to be released in strict reverse order
at the end of the statement. However, nested stored proedures and partition
tables break this rule. We now allow the locks to be deleted from the
trx->autoinc_locks vector in any order but optimise for the common (old) case.
