This adds support for building for mips64* architectures by using the
--use-cc-builtins configure option for ConcurrencyKit. Which is a
temporary workaround until proper MIPS supported is implemented in CK
upstream.
Closes GH-318.
Bump minimum MACOSX_DEPLOYMENT_TARGET to 10.6
The macOS SDK for 10.4 has been deprecated as of 10.14, bump to 10.6 so that LuaJIT continues to build out of the box.
Fixes LuaJIT#484.
In drv_mysql.c do not assume MYSQL_OPT_SSL_MODE to be a preprocessor
define. It is an mysql_option enum value with all MySQL
versions. Instead, do a configure-time check if that value is defined in
mysql.h.
When the --rate option was used together with the --time option, a bogus
"Terminating the event generator thread failed" error was thrown at the
end of the test.
Worker threads used sleep() in the bounded rate mode to avoid CPU
hogging when polling on the event queue. The problem was that sleep()
calls increased time spent by events in the queue, which is counted
towards event latency to avoid the coordinated omission problem. The
lower the rate, the bigger impact on latency was observed.
The fix is replacing sleep()s with a condition variable which is now
used to put worker into an idle wait when the queue is empty. The event
generation thread now uses pthread_cond_signal() after each generated
event to wake up an idle worker thread. Which somewhat increases
sysbench CPU consumption, especially for high rates.
api_sql_mysql.t failed if SBTEST_MYSQL_ARGS included an explicit
specification of '--mysql-socket', in which case ignores --mysql-host
and asssumes 'localhost'.
If the MySQL driver is available and --db-driver option was explicitly
specified, assume MySQL and don't compain about multiple DB drivers
being available.
That was a popular request and is likely what most sysbench users want.
