Intended to be used from fatal signal handlers. As the statement will
be returned only while classification is in process, if a statement
is returned, it is an indication that the crash was caused by the
classification.
According to bug-report it seems that a SrcList can be NULL. This
fixes the immediate problem, but it would be good to know in what
contexts the SrcList can be NULL so that the check could be made
before calling the function instead of checking (possibly
unnecessarily at times) in the function.
GCC is smart enough to detect that the address of a local variable is
returned. Since this appears to be code used for a debug assertion, we can
just return a null pointer.
This correctly triggers the session command response processing to accept
results from other servers than the current master backend if the session
can continue. If the session cannot continue, it will be stopped
immediately.
Fixed leak in load_utils.cc and the cache filter. Also changed all
instances of json_object_set with json_object_set_new to make sure it's
only used when the references are to be stolen.
The Connection class used the wrapper function when it could simply call
mysql_real_connect directly. This removes the unconditional error message
that would be printed even when a connection failure was expected.
Removed the inserts from the test. They don't make any functional
difference and it only slows the whole system down.
Also reduced the number of threads doing the change user command. This
should reduce the CPU usage of the test.
This should help stabilize the test set by making sure the test actually
fails twice. This'll still leave the output in the log so that the
problems that only occur on the first run can be eventually fixed.
This script is capable of setting the change date and not just
updating a specific one.
It looks for " Change Date: .*" in the first 20 lines of file and
replaces whatever follows "Change Date: " with the specified change
date.
If provided with a directory, it will walk the directory hierarchy
and recursively set the change date in all files.
The shutdown signal handlers were installed before the workers were
initialized and weren't removed before the workers were deleted. This
would lead to a debug assertion and an eventual crash when a SIGTERM
signal was received outside of the expected scope.
The proper way to do this is to install the handlers only after the system
is up and running and to disable them as soon as the shutdown process
starts.
This mostly happened with the mxs621_unreadable_cnf test as it seemed to
receive a SIGTERM during the execution of the at-exit handlers.
For whatever reason, galera complains on startup about
wsrep_cluster_address missing even when mysql_install_db is run. By making
sure that we configure it before we initialize the database, the problems
seem to go away.
Problem was that 'handler' is a keyword. To make it work,
the keyword must be listed as one of those that turns into
an id where it cannot be used as a keyword.
