PerlAddVar ?
It would be nice, in my opinion, to have some way of doing:
PerlAddVar Fred "Value 1"
PerlAddVar Fred "Value 2"
And then in your script:
my @values = $r-dir_config('Fred');
which gets ("Value 1","Value 2") in @values.
Any thoughts on this? (I'm not set on the name PerlAddVar, if that's
anyone's concern - but what about the idea of it?)

Perl blocks get evaluated in the Apache::ReadConfig namespace, which
knows nothing about location it's placed in. What you can do is to set
FQDN variables from within Perl section:
Perl
$MyEnv::FOO = "bar"
@MyEnv::FOO = qw(bar foo);
%MyEnv::FOO{bar} = "barfoo";
/Perl
It doesn't matter whether you define the package MyEnv or not, since it's
autovivified when first time referenced to.
and then in your code:
print $MyEnv::FOO;
will do.

The thing I don't like about this is that I'm writing code for non-perl
programmers. Littering .htaccess files with perl code is not something I
want to be getting into. I don't mind too much the work around that is:
PerlSetVar MyVar "name = value, \
other = value, \
etc = continued"
but I don't particularly think its well suited to setting multiple values
for non-programmers, and it breaks as soon as you start needing spaces in
values or something wierd that happens to break the parser code (from the
Eagle book).

Strange mod_perl problem
I have several CGI scripts that I am in the process of moving to a new server using mod_perl and Apache. The scripts connect to an Oracle database using the Oraperl module wrapper for DBI and DBD::Oracle. Basically the scripts display a simple for for user input, this works fine. When the form is posted the script connects to a database, queries using the parameters provided, and returns a short report to the user. The scripts run fine as CGIs, but when I run them under mod_perl I'm not getting any output from the database after the form is posted. What's really strange is that I'm not getting any Oracle errors either. The return page has the proper HTML and BODY tags, but no data at all. I've tried running the script with and without the Apache::DBI module loaded, but it didn't make any difference. A check of the perl-status shows all the appropriate (I think) modules loaded for mob_perl. I'm stumped! Any help would be appreciated! Please CC replies to my email address.

It's probably because you are subscribed by the address different from the
one you send the unsubscribe request from. If you read the reponse that
you get when you send to [EMAIL PROTECTED], you will see how to
unsubscribe from the mail account different from the one listed in the
mod_perl list db.
Hope this helps.

Apache::Registry and clearing package name space
Hello,
I am having a problem clearing variables and aliases
in a temporary package name space. The source of the problem
is in making legend cgi scripts work under Apache::Registry.
But the problem can be isolated and shown by the following
demo program:
$ cat foo.cgi
#!/usr/bin/perl -w
use strict;
use Symbol qw(delete_package);
print "Content-type: text/plain\n\n";
%Q::userdata=();
$Q::userdata{first_name}='first_name';
$Q::userdata{last_name}='last_name';
*Q::hello=\hello;
print "here is the symbol table\n";
while (my($k,$v)=each %Q::) {
print "$k = $v\n";
}
delete_package('Q');
sub hello {
print "hi\n";
}
The first time it runs, it yields:
here is the symbol table
userdata = *Q::userdata
hello = *Q::hello
But there after, modperl shows emtpy symbol table.
In my actual implementation, delete_package is used
inside a PerlCleanupHandler. But the behavior is the
same: the symbol table is completely gone even if
I reinitialize the variables and aliases at the start
again.
Does anyone know a way around this? In perlfaq7
another method using scrub_package is mentioned.
But that one is not appropriate because if a subroutine
is aliased, that scrub_package will make the original
subroutine undefined, causing havoc all over the place.
Thanks for any info.
Richard

2 server setup w/mod_proxy with a per-filename filter
hi, I'm trying to implement a one light + one fat apache server setup and I'm stumbling with the lack of an option to proxy-pass based on filename. It seems that mod_proxy is designed to handle complete hostnames and directories, and I'm wanting it to proxy everything that looks ~ \.pl$ The only workaround I foresee might be using mod_rewrite, but I'd rather not :), does anyone have a better idea? Or maybe a few examples of mod_rewrite use that work in this case? Of course, the reason of my woes is that I started designing with only one 'fat' httpd, and my websites have *.pl and *.ehtml files (for Registry scripts and Embperl files) intermingled within the directory structure, not separated.

Ah so that's why I couldn't get it to work!!!
I was trying to solve this yesterday, and was completely bamboozled why
even the $^A and formline implementation didn't work (although I might
have been doing something wrong). Anyway, the solution I came up with was
just sprintf:
##.## becomes %2.2f
.## becomes %4.2f
Pad all strings with (" " x 80) before using, and set their length with:
%.25s for a max 25 char string.
Or prefix the string with (" " x 80) for right-justifying.
Works like a charm.

Bitten by -D_FILE_OFFSET_BITS=64
Hello, (This may be a general Perl question but since I have this problem only with mod_perl I'm asking it here.) Perl's (5.6.0) Configure script puts -D_FILE_OFFSET_BITS=64 into Config.pm's variable ccflags in my machine (redhat 6.1 with linux 2.2.12). This causes for some reason mod_perl.c to have stat structure with size 96 while it has the size 88 in apache (and it is 88 usually). The result is very poor behavior in make test. When I manually remove that compiler directive everything works fine. My mod_perl is 1.23 and apache is 1.3.12. I believe I've had this problem for long since over the years :-) I've had this same problem occasionally but only now investigated it thoroughly using gdb. Can anybody give an explanation what is going on here? The member finfo has the type struct stat in request_rec in httpd.h. Regards, Ari Jolma

mod_perl httpd binary suddenly stops working
Hello, I have a mod_perl/apache binary and configuration file that I've been using successfully since October of last year. Last week I ran out of disk space (and might possibly have had the server flake out over the CPU overheating). Everything appears to be running smoothly now with a larger fan and more disk space, except the original httpd binary and config file I had refuse to start - it simply exits without any error messages or log entries and without daemonizing and spawning the necessary httpd children. httpd does not show up in the process list at all. I've tried to recompile httpd, but I keep getting segfaults when I try to use any mod_perl programs, and I was hoping that instead of troubleshooting a new compilation that perhaps it might be easier to resolve the once-working one. Are there any kinds of tracing tools or debugging tools that might help me figure out why the old httpd suddenly is having problems? --James
sticky variables...
first time post here :)
I'm having a problem with some varibles changing mid-way thru the code and
then back again. I have a program called 'cr' in the mod_perl directory.
It's not a module, it's just a straight cgi script. It uses strict. Here's
a samepl of the code:
my ($cookie_ref,$sid,$cid) = check_oven_for_cookies($realsid);
print "sid before call: $sid\n";
show_form;
print "sid after call: $sid\n";
here's the sub (which resides inside of 'cr'):
sub show_form {
print "inside function: $sid\n";
other stuff
}
This 'cr' program gets hit about 5 times a second at peak times. About 10%
of the time when I just keep hitting "reload" on the browser, occasionally
the $sid will be DIFFERENT inside the function. actually it changes to
someone elses $sid that is presumably running the program at the same time.
But the $sid is always my personal $sid before and after the function.
that's consistant. it's just when I make the function call that seemingly
at random I get someone else's $sid!
Any ideas? Would it fix things if I converted cr to a module and stuck all
the functions into Cr.pm and just had cr calling the functions, passing
$sid around instead?? I changed all my exit's to Apache::exit recently but
that didn't fix it. I checked for nested subs, but I don't have any. Any
help would be appreciated, :) thanks.

Re: environment

The problem is that after a couple of reloads, the environment variables seem to get cached and the result comes out -obviously- wrong. I guess my question is: Is there any way to ensure that the script will get the right environment variables? maybe something in the apache configuration file? i don't like to rely on %ENV in a mod_perl environment. there are just so many better ways of doing this using the Apache API we havebut: http://perl.apache.org/guide/control.html#Wrapper_to_Emulate_the_Server_En i'd recommend doing things w/PerlSetVar and such: http://perl.apache.org/guide/config.html#PerlSetVar_PerlSetEnv_and_PerlP ky
pod and EmbPerl
Does anyone know whether it is possible to pod-ify an EmbPerl document? When embedding pod directives in my EmbPerl pages and then running pod2html on them, the pod2html interpreter returns a blank page. thanks, Ed
RE: $r-get_handlers bug/oversight?
hi again...
I'm having lots of problems with the get_handlers method... the following is
reproducible for me under 1.22, 1.23 and the latest cvs using 1.3.12...
---
#!/usr/bin/perl
my $r = shift;
my $list;
my @array = qw('test' 'array');
$r-pnotes(TEST = \@array);
$r-push_handlers(PerlLogHandler = sub {
my $pnotes = $r-pnotes;
foreach my $key (sort keys %$pnotes) {
warn "this is the key $key";
};
});
#$list = $r-get_handlers('PerlLogHandler');
$r-send_http_header('text/plain');
foreach my $key (@$list) {
print "$key\n";
}
print "done!";
---
running as is prints the pnotes keys.
uncommenting the get_handlers method gives:
Attempt to free unreferenced scalar.
and no other output, yet a code reference is visible in the browser...
The other thing is that this only seems to be an issue for code references -
if I push My::Logger instead of a subroutine, all is fine...
Am I using push_handlers incorrectly, or is get_handlers mucked up (or can
nobody reproduce this)?

Hi all...
I've noticed that get_handlers() will return the enabled handlers
for a PerlPostReadRequestHandler, but not when it is specified as a
PerlInitHandler (either by calling
$r-get_handlers('PerlPostReadRequestHandler') or
$r-get_handlers('PerlInitHandler'). It is the same with
PerlHeaderParserHandler. An oversight?
Also, I can't get anything for PerlCleanupHandlers, which kinda
makes sense, since Cleanup isn't really a phase, per se (at least
according
to the book). Does it make sense to add this to get_handlers() as well?
oversight. neither CleanupHandler nor InitHandlers is in the
handler_table in Apache.xs. probably because those directives were added
after get/set handlers was implemented, and the table was never updated.
i'll see about fixing that.
RE: Bitten by -D_FILE_OFFSET_BITS=64
Sorry about the previous blank reply.
This has been fixed in a post 1.23 patch.
Change the line
$PERL_EXTRA_CFLAGS = "";
to
$PERL_EXTRA_CFLAGS = $] = 5.006 ? $Config{ccflags} : "";
and try again.
