Hello. Indeed, I found following message in release notes of BIND
9.6.1-P1 ( http://oldwww.isc.org/sw/bind/view/?release=9.6.1-P1 ):
Which you should have seen came *after* 9.6.1 was released.
The CHANGES file is in reverse chronological order.
2581. [contrib] dlz/mysql set MYSQL_OPT_RECONNECT option on connection.
Requires MySQL 5.0.19 or later. [RT #19084]
2580. [bug] UpdateRej statistics counter could be incremented twice
for one rejection. [RT #19476]
--- 9.6.1 released ---
dlz/mysql set MYSQL_OPT_RECONNECT option on connection. Requires MySQL
5.0.19 or later. [RT #19084]
But there is no output from the second command:
$ tar xf bind-9.6.1-P1.tar.gz
$ grep -r MYSQL_OPT_RECONNECT bind-9.6.1-P1
$
I've tested it. BIND still doesn't reconnect. After applying patch
mentioned earlier, BIND starts to work properly.
I believe this patch should be commited (as is committed in 9.7.0a3):
$ diff bind-9.7.0a3/contrib/dlz/drivers/dlz_mysql_driver.c \
bind-9.6.1-P1/contrib/dlz/drivers/dlz_mysql_driver.c
795,797d794
#ifdef MYSQL_OPT_RECONNECT
my_bool auto_reconnect = 1;
#endif
929,939d925
#ifdef MYSQL_OPT_RECONNECT
/* enable automatic reconnection. */
if (mysql_options((MYSQL *) dbi-dbconn, MYSQL_OPT_RECONNECT,
auto_reconnect) != 0) {
isc_log_write(dns_lctx, DNS_LOGCATEGORY_DATABASE,
DNS_LOGMODULE_DLZ, ISC_LOG_WARNING,
mysql driver failed to set
MYSQL_OPT_RECONNECT option, continuing);
}
#endif
BTW, why there are only #ifdefs without #define in 9.7.0a3? Is user
forced to set this option himself to make it work?
No. MYSQL_OPT_RECONNECT is only in some versions of mysql. If you have
a version which supports MYSQL_OPT_RECONNECT then MYSQL_OPT_RECONNECT will
be defined.
