How do i know for certain i am using SSL?
Hi, is there any method that will work through all the different
apache ssl implementations?
Currently what i do (with openssl) is:
my $s = $r-lookup_uri($r-uri);
my $ssl = $s-subprocess_env('HTTPS');
$ssl becomes 'on' , but i don't know if this is compatible with other
ssl implementations.
Maybe this HTTPS env could be mapped to mod_perl %ENV, or using
something similar for each ssl
implementation so that a developer could trust on one place to know
whether the request is using ssl or not.
Thank your for you attention,
Joao Pedro

Re: module multi-config strategy
Perrin,
you mean that I can actually set my environment per virtual-host?
that's encouraging in the one-implementation per site scenario. Now I
does block any use of persistent variables, unless I store them in a
RDBMS or in the 'Globals' module you mentioned. It could really be a
module that just exported references to internal hashes. I'm starting to
like it.
A module that exported persistent hashes (not across server restarts,
just across requests ... short lived persistence). Maybe it could be
loading the 'config' hashes from disk every once in a while, say every
10 seconds, to be able to reconfig without restarting. And the ability
to commit a given hash ('config') to disk to make it permanent.
mmmh. an idea is shaping here in my tiny head ... anyone care to
comment?

You can have a module full of globals that is different for each site (it
doesn't have to go in the same directory as your other shared code), or
you can put things in httpd.conf with PerlSetVar and read them with
$r-dir_config(), which allows a separate configuration for each virtual
host.

Re: How do i know for certain i am using SSL?
Following your suggestion,
use Apache::URI ();
$r-parsed_uri-scheme;
returns http or https.
However this value comes from apache's util_uri
where https is mapped to DEFAULT_HTTPS_PORT.
src/include/httpd.h:#define DEFAULT_HTTPS_PORT443
However with OpenSSL and mod_ssl, this still works because somewhere at
ssl_engine_ext.c
DEFAULT_HTTPS_PORT is overwritten and the schema returns https on other
port when ssl is engaged.
So, the question is, can i trust this?
Thanks,
João Pedro

Apache::ASP
Hi : I copy the ./site/eg/ directory to /home/httpd/asp. (this directory is created by me. ) From the Quick Start of Install page : You must put "AllowOverride All" in your httpd.conf config section to let the .htaccess file in the ./site/eg installation directory do its work. This means I need put the following lines in the httpd.conf ? Directory "/home/httpd/asp" AllowOverride All Order allow,deny Allow from all /Directory If you want a starter config file for Apache::ASP, just look at the .htaccess file in the ./site/eg/ directory. Can I just cp the .htaccess file to /home/http/asp ? Do I need change the PerlSetVar Global (from /tmp to /home/httpd/asp ??) and PerlSetVar StateDir ( from /tmp/asp_demo to /home/httpd/asp??) ?

Apache::ASP version conflicts
I'am currently having trouble with asp and perl. Here's the situation. Recently perl was upgraded to 5.6, all the other programs including httpd see perl as 5.6 with the exception of the asp module. It's installation script (Makefile.pl) sees and uses perl 5.6 however version.asp reports the previous version of perl. "This is version 5.00503" ASP not using the newer version of perl is making a few of the scripts not run correctly. I've checked all the paths I could find with the various asp files and they're all points to the correct place but it still doesnt help. Where else should I check or is there something I'am overlooking?

Ok, so are you actually going to write a VBScript to perl parser? I was actually
thinking of undertaking this project myself, but I've never written a lexer or a
parser or anything like that. If you _are_ going to do this I'd be glad to help. If
not, I'm probably going to get started with it anyways. I realized a huge need for
something like this since I've been working on a large site (high volume + large
codebase) converting from WinNT/ASP to Solaris/Perl/CGI (with mod_perl of course).
I've written a _really_ simple script that converts stuff like "For i = 1 To 10" to
"for (1..10) {" etc., but it's of course really flaky and unreliant (although it
knocks out about 90% of the manual code conversion).
Ok, so what was the point again?? Oh yeah, are you really going to do this? :-)
Or is someone else already in the process?
Like Matt suggested you can start with his simple vbscript to
perlscript converter, but I would recommend to do a really
complete job that you use a full on grammar and something
like Parse::Yapp to do the parse tree. I personally would
find this approach the most enjoyable, but it may be that
the parse times that result from this are too slow, and you
might need to take the approach that Matt did and brute
force your way through the code to render to perlscript.
I have not started on this, and likely would not for a while
yet so feel free to have at it. If you decomped this
functionality into a module like Parse::VBScript or
some such ( I don't know about this CPAN namespace ) and
presented an interface like:
my $vbparser = Parse::VBScript-new($string_ref);
my $perlscript_ref = $vbparser-perlscript();
this interface would allow me to use your code from
Apache::ASP easily by passing the VBScript code into
the parser, and get the equivalent perlscript. The
passing by ref would just save on some of the string
copying that may be unnecessary otherwise.
There is a HUGE need for this vbscript emulation, and this
would greatly add to the functionality of Apache::ASP, so
many thanks ahead of time!

Re: mod_perl success!
Pramod:
We are actually going to be generalizing it and releasing it (maybe) but
we need to get approval first, so can't just send the code :) It'll
probably happen in a few weeks though.
So here's what you have to do:
- Clean up the systems-level modules (like database stuff, base libraries)
and packages that are used a lot (stuff like date conversions and other
random operations) by making sure they pass "perl -w" and "use strict"
- Install mod_perl into Apache
- Make Apache handle CGIs through PerlRun with PerlRunOnce Off
- Put the clean packages that you want to keep in memory in a startup.pl
file that is PerlRequire'd by the httpd.conf file
- Write the handler (more details below)
- After the PerlRequire statement, install the handler as a
PerlCleanupHandler
That should do it.
Here are the details about the cleanup handler in pseudocode:
BEGIN {
load the list of packages that are in memory now into a global variable
}
sub handler {
look through the list of packages in memory and see if there are entries
in the global variable
if not, then flush them out (code you can copy from PerlRun.pm in
mod_perl source)
after flushing it out, then clear the entry in %INC
}
The BEGIN {} makes it so that you NEED to load this handler after the
startup.pl stuff because otherwise the handler will flush the clean
packages you have listed in the startup.pl file.
Also, we actually wrote a database package that acts exactly like
Apache::DBI (but has some customized features) so we didn't end up using
the Apachage::DBI package. However, for persistent connections this might
be something that you want to look into.
I hope this makes sense. Let me know if you have any questions. If you can
wait a few weeks (2-3) you can just grab the handler from me :) Just so
you know, after all the optimizations that we have been able to
practically deal with (cleaning systems modules, that kind of thing) we
are getting 100%-400% speed increases. Pretty nice, huh?

Hi Andrew,
I've been following your mails regarding porting your CGIs to mod_perl on
the mod_perl mailing list, but I got lost after a few mails. But I know
that you celebrated success at the end of it allanother mod_perl sucess.
Basically, the reason I'm writing to you now is because I have the exact
same challenge as you had when you started this project - migrate CGIs to
mod_perl. As with your case, our code is too dirty to use Apache::Registry,
so I have to use Apache::PerlRun. Our code base is huge and our application
is very database intense, in the sense that there are too many calls to the
database.
I would appreciate if you could tell me in as much detail as possible about
how exactly you went about doing this migration. I know this is too much
trouble for you, but you'll be helping another soul a lot :)
I'm not in a big hurry, so you can take your time to write this up. It'll
be really useful if you can give me as much details as possible. If you
already have a document that you wrote about this, that would great too.
Thanks in advance!

RE: Newbie Installation Problem
The permissions problems don't appear to be with the ExtUtils directory. It's trying to mkdir /usr/lib/perl5/site_perl/5.005/i386-linux/auto/Apache/include. Somewhere among those directories you don't have permission. And, I misspoke before about PREFIX. First, PREFIX doesn't do everything correctly. You need to use 'LIB=/tmp/foo/bar INSTALLMAN3DIR=/tmp/foo/bar/man'. Second, PREFIX, LIB or whatever for mod_perl needs to be added to 'perl Makefile.PL' as so: perl Makefile.PL whatever mod_perl/apache options you're setting LIB=/tmp/foo/bar INSTALLMAN3DIR=/tmp/foo/bar/man On 25-Jul-2000 Adelaide Yip wrote: I tried doing PREFIX=/usr (I'm using Redhat layout), but still the same error.

further adventures with taint
Solaris 2.6, Perl 5.6, apache 1.3.9, mod_perl 1.24. I see intermittent Apache error_log entries like: [Mon Jul 24 04:08:02 2000] [error] Insecure dependency in require while running with -T switch at (eval 85) line 3. Here's what perldiag says: Insecure dependency in %s (F) You tried to do something that the tainting mechanism didn't like. The tainting mechanism is turned on when you're running setuid or setgid, or when you specify -T to turn it on explicitly. The tainting mechanism labels all data that's derived directly or indirectly from the user, who is considered to be unworthy of your trust. If any such data is used in a "dangerous" operation, you get this error. See the perlsec manpage for more information. OK, I (normally) run with PerlTaintCheck on, and I've read perlsec. My PATH is ''. How can I find out where this insecure dependency _is_, so I can turn taint back on? The timestamp tells me which script failed, and it uses a whole slew of modules. use strict; use Apache::Constants qw/:http/; use LWP; use tuner; use MIME::Lite; use HTML::Parse; I suspect MIME::Lite, but the code won't work if I remove it. How can I be sure if it's to blame, os I can attempt to patch it (or its dependencies)? Is there anything like a Taint::Carp, that'd give me a full back-trace from the insecure code (and works under mod_perl)? Running with PERL5OPT=-d is no good; the problem never shows up. perl -cwT shows nothing (which confirms that it's a runtime error, I suppose). The Guide, perlrun, perlsec, and the perl books I've read are... a little weak on Taint debugging techniques. If I can ever work through the problems I'm having, I'll be delighted to contribute some docs on this. I'd really like to run with PerlTaintCheck on - any ideas? thanks, -- Mike
