Logfile Error: \t(in cleanup) Not a reference to a Digest::MD5 object.\n

[prev] [thread] [next] [Date index for 2005/02/13]

Hi all,

I'm running the latest release of MP2 on FreeBSD 5.3 (more details=20
below). One part of my site takes a user's password submitted from a=20
form, encrypts it using MD5, and stores that encrypted value in my=20
database (Postgres 7.4.7). Sometimes it works, sometimes it doesn't.=20
When it doesn't work, the Apache log file reports:

[Sun Feb 13 11:51:52 2005] ...blah blah blah
         (in cleanup) Not a reference to a Digest::MD5 object.
[Sun Feb 13 11:51:52 2005] [error] [client 192.168.0.6] \t(in cleanup)=20=

Not a ref
erence to a Digest::MD5 object.\n, referer:=20
https://192.168.0.3/CHANGEMYDETAILS
Insecure dependency in open while running setgid.

Does anyone know offhand what is going on here? I think the problem=20
could probably relate to the MD5 hashing perl subroutine that I use,=20
partly because the log mentions a problem with an MD5 object, and=20
partly because when I replace it with a dummy subroutine that just=20
returns a hardcoded string, the errors do not seem to arise. I can't be=20=

sure that this is the problem, however, because as I say, even with the=20=

real subroutine being called, sometimes it works, sometimes it doesn't.=20=

Anyway, the code I use for that subroutine is:

# based loosely on code in the Eagle book, p.217
sub make_db_MAC {
=09
	# NB1 '' =3D the empty string i.e. two single quotes
	# NB2 DBSECRET is declared as a constant (i.e. use constant =
DBSECRET=20
=3D> '...';)
=09
	my ($interim) =3D MD5->hexhash(join('', DBSECRET, @_));
=09
	my ($db_mac) =3D MD5->hexhash(DBSECRET . $interim);
=09
	return $db_mac;
=09
}

One last piece of information. When it doesn't work, most browsers do=20
nothing. Safari in OSX, however, reports:

The error was: =93bad server response=94 (NSURLErrorDomain:-1011)

Any suggestions most gratefully received (I've been working on this for=20=

hours already.)
