JOB - US/CA/SF - Looking for a well rounded Linux/Apache/mod_perl/mysql SysAdmin
Hi all, We're in need of a SysAdmin/Developer in Training type of person.

RE: !--#config timefmt=blahblahblah-- with Apache::SSI

Subject: !--#config timefmt=blahblahblah-- with Apache::SSI
Hi,
Does anyone knows, why standard SSI-Tag: !--#config timefmt="%blah"--
doesn't work with Apache::SSI (maybe it's currently not supported)???
Other used SSI-Tags are interpreted perfectly by Apache::SSI.
Thank you,
Stephan
I came across this as well when one of our templates which uses SSI to
format a time.
I subclass Apache::SSI and overwrote the ssi_echo and echo _DATE_LOCAL
method. As far as I can tell there is an environment variable called
DATE_LOCAL which keeps sub_DATE_LOCAL from ever getting called and this
seems to ignore any settings made through the ssi_config method in
Apache::SSI. Probably a better way to fix this, but this works for me. --

package MySSI;
sub BEGIN {
use Date::Format;
use base qw(Apache::SSI);
}
sub ssi_echo {
my($self, $args) = @_;
my $var = $args-{var};
$self-_interp_vars($var);
my $value;
no strict('refs');
if ($var eq 'DATE_LOCAL') {
return $self-echo_DATE_LOCAL;
} elsif (exists $ENV{$var}) {
return $ENV{$var};
} elsif ( defined ($value = $self-{_r}-subprocess_env($var)) ) {
return $value;
} elsif (defined {"echo_$var"}) {
return {"echo_$var"}($self-{_r});
}
return '';
}
sub echo_DATE_LOCAL {
my $self = shift;
if(exists $self-{timefmt}) {
return time2str($self-{timefmt},time) ?
time2str($self-{timefmt},time) : scalar localtime;
}
return 1+time;
return scalar localtime;
}

IPC::Cache and how to clear the cache
Hi all, I'm not sure if this is an appropriate place to ask. I've looked over the "Guide" and couldn't really determine for sure how to do this. I am using the IPC::Cache module to store some configuration information in shared memory for mod_perl modules that I've written. The problem I'm facing is that I want to be able to clear the cache on stops and restarts, but in order to do this correctly and to ease my paranoia, the clean up method should only be called by the parent process and only once when the parent process exits. So I was thinking of creating a handler for the PerlRestartHandler phase. However I had some questions about how this phase gets called and if it gets called at all when stopping the apache server (i.e., apachectl stop). I'm assuming that the child apache processes are not involved at this point in the phase so any methods called at this point are executed only once by the parent process as it exits. Yes/No? Can someone confirm my thinking here and let me know if there is a better way to perform one time cleanup/execution of code during server exit--kind of analogous to the startup.pl file and it's function during startup. BTW, I've also thought about using a DESTROY or END method to the start.pl file, but wasn't sure that they are called at server exit by only the parent process. Furthermore, I thought about taking an "if defined then reset" approach in the startup.pl, but I wanted see if there was a cleaner way of doing this. thank you in advance, sang
panic: POPSTACK, Callback called exit and Apache::Session's die seems to be resurrecting itself
Hi,
Can someone help me out here?
Apache_1.3.12
mod_perl 1.21_03
Apache-Session-1.03 ( Database and deamon locker for storing and locking
sessions )
-- code snippet --
sub getSESSION {
my $self = shift;
my $sid = shift;
my %SESSION;
eval {tie %SESSION, 'Apache::Session::DBI', $sid;} if ($sid);
if (! $sid || $@ ) {
eval {tie %SESSION, 'Apache::Session::DBI', undef;};
}
return \%SESSION;
}
So if I pass what I know to be a bogus non-null session id (no longer a
valid id in the database) it tries the first eval. Based on my understanding
of the Apache::Session docs, it should die (shouldn't it?), which should
result in $@ being non-null and the first eval should return undef. Then I
should be able to call another eval block requesting a new session.
Is this right and if so, why am I getting the following messages in the log
file?
panic: POPSTACK
Callback called exit.
for each httpd process.
I looked at the eval documentation and I've tried using Carp, localizing
$SIG{__DIE__) within the eval, but at this point I'm utterly confused and am
not sure what is really the cause of the problem. I think that it has
something to do with the way perl's die function is being called within this
eval because I don't have this problem when the session id I pass is a valid
one.
Help.
thank you,
Sang
