Greetings. I'm running Apache/1.3.12 with mod_perl/1.24 and mod_ssl/2.6.4 on a Debian
system.
(I know mod_ssl and mod_perl on the same server is begging for trouble, but that's the
way the
site was designed, well before I got there...) We recently recompiled the server with
mod_perl's EVERYTHING=1 to support some code I'm working on which uses stacked
handlers.
We use Apache::DBI (via PerlModule) to cache connections to a MySQL database. For some
reason,
when a PerlHandler runs that accesses the database (or perhaps on ChildInit), we get
several
dozen warnings of the following type dumped to the log:
Subroutine dump_results redefined at /usr/lib/perl5/5.005/i386-linux/DBI.pm
line 1100,
<FILE> chunk 13.
The warnings all seem to be coming from DBI.pm. It was also doing this with CGI.pm on
server
load, but that's Gone Away, for reasons unclear. We get this errors with
PerlFreshRestart
either On or Off. Obviously turning PerlWarn Off makes them stop, but it also makes
code
testing difficult. Everything seems to run fine in spite of the warnings, but they
make the
logs unreadable.
Currently, the best solution I have is the following, shamelessly borrowed from slash:
<Perl>
$SIG{__WARN__} = sub { warn @_ unless $_[0] =~ /Subroutine [\w:]+
redefined/io };
</Perl>
However, that's a band-aid, not a fix. I checked for multiple installations of DBI
just in case
-- no luck. I have RTFM, twice. I searched through the list archives and have not
found discussion of this particular problem. What I'd like to know is what's causing
these warnings and how to make them stop (not just how to keep them from being dummped
to the log).
Information on our perl and apache installations follows. Any suggestions would be
appreciated. Thanks.
