Hi, I get the following error in the log file when I start ZM v1.20.1
Why is it not displaying the wrong values ? 'ZM_DB_SERVER'=localhost ?

I enabled logging in mysql to the mysql.log file, and although i still see the error above form zmtrigger.pl

In the sql log everything seems fine.

Here is a snippit.

In zmtrgger.pl, (ZM 1.20.1)

replaced
my $dbh = DBI->connect( "DBI:mysql:database=".ZM_DB_NAME.";host=".ZM_DB_SERVER, ZM_DB_USERA, ZM_DB_PASSA );

with

my $dbh = DBI->connect( "DBI:mysql:database=".&ZM_DB_NAME.";host=".&ZM_DB_SERVER, &ZM_DB_USER, &ZM_DB_PASS );

from zmfilter.pl in 2 places.

Now there is no more errors in log file.

Yes, this was a problem in zmtrigger.pl that I'd already corrected for the next version, but not got around to mentioning here.

Phil

Is that problem in other files in 1.20.1 as well? The version lacking the '&'s seems to be present in zmaudit.p, zmfilter.pl, zmpkg.pl, zmtrigger.pl, zmupdate.pl, zmvideo.pl, and zmwatch.pl.

No. The problem was with ZM_DB_USERA and ZM_DB_PASSA rather than ZM_DB_USER and ZM_DB_PASS (without any 'A's). The & I think is just a way of getting perl not to complain about references and whilst it won't hurt should not be necessary if the constants are correctly defined. This was just in zmtrigger.pl btw.

Phil

I made a new RPM that has this correction in it. The source RPM is there as well.

Hmmm... The '&'s do seem to be needed within the BEGIN block. If they're not there the script gets a bit confused:Presumably within that block things are still less than perfectly defined, or something...

Yes, sorry. I didn't actually twig that it was the instance in the BEGIN block that was being discussed. You need the & in there, but don't anywhere else in the script.

It's updated in 1.21.0 to be correct in both places even though it sounds like I have no clue what I'm talking about!

Phil

Cheers! When's 1.21.0 escaping?

Escaped!!
