Description aaron brick 2002-01-23 21:04:54 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 Galeon/1.0.2 (X11; Linux i686; U;) Gecko/20011224

Description of problem:
one can run /etc/init.d/mysqld start and since it backgrounds the safe_mysqld
process and doesn't do any mysqladmin pinging, the server isn't guaranteed to
have started. this causes problems if steps soon after the server (re)start
depend upon it.


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. run /etc/init.d/mysqld restart
2. try to make a mysql query right away
3.
	

Actual Results:  the client failed to find the socket by which to communicate
with the server.

Expected Results:  step (1) should have waited for the server to come online
before returning. then (2) would succeed.



Additional info:

the debian start script (/etc/init.d/mysql in the mysql-server package) does
this rationally, by mysqladmin pinging a number of times until the server comes
online or dying after a timeout.

Seems like a good enhancement.

Comment 2 Patrick Macdonald 2003-08-12 17:33:18 UTC

Kim, can you handle this please.  Have the script loop five times with a 1
second hold. Break out of the loop if the mysqladmin ping succeeds, bail otherwise.

Comment 4 Patrick Macdonald 2003-10-27 20:32:04 UTC

Fixed in rawhide.  We chose to wait for a max of tens seconds, pinging every
second.
