Probably not. I think you'll find that it *does* time out, just after a
longer period than you'd prefer. Timeouts of 30, 60 and 120 seconds are
common in network code, because it's not possible to rel
Hi guys,
I used mysql_ping() function in my program. But when I unplug the network wire
between client and MySQL server, my program has no response as mysql_ping() can
not return value and hanged there.
Is this a bug of mysql_ping() ? or any other advice?
thanks
Hello,
I am having issues with the MySQL C API. I have googled, and it seems
many other people are having this issue too, but unfortunately I have
yet to find a solution.
It seems that whenever anything calls mysql_ping(), it causes a
Segmentation fault. I am currently using MySQL 4.1.10a
Hi again,
This is intresting, the documentation indeed mentions that mysql_ping
indicates "Zero if the connection to the server is alive" and not that
"zero if the server is alive", as I *naturally expected* also, so it
is kind of tricky this one. I would expect the sam

I've found that mysql_ping doesn't work properly with TCP connection (in
your test case you put the hostname to "127.0.0.1"). My program was
working with "localhost" - connection through the Unix socket. You may

Hi,
The previous subject made me wonder about mysql_ping () in a multithread
environment. Since it implements restoring connectivity, should it also
be protected by a mutex?

I did some extensive testing and it looks like that only the first
mysql_ping () fails to reconnect or very possibly returns the wrong
result. I am currently using v4.1.14.

That works if only mysqld is down and the machine is rea

So - indeed - I'm probably barking up the wrong tree, by looking at
mysql_ping(),
but I basically want to mimmick the behavior, so the there's no connection
error
for the webserver involved.

Indeed, mysql_simple_command (with COM_PING command like argument ) is used
by C API mysql_ping, to check connection.MYSQL struct it's used like

For a connection you must use in order:
mysql_init(),-initialise MYSQL struct
mysql_options(),- optio
