RE: Apache::Registry - END Block not being called when script reloaded
-Original Message- From: Chris D'Annunzio [mailto:[EMAIL PROTECTED]] Sent: Friday, January 12, 2001 3:25 PM To: [EMAIL PROTECTED] Subject: Apache::Registry - END Block not being called when script reloaded [snip] The usual behavior for Apache::Registry is to explicitly call the END block each time the script runs. However, I have found that if I modify the main script and then execute a request without restarting the server, the END block is not called in that 1st request where the script is reloaded. After the first request, the behavior returns to normal. Is this a known bug or is there some other reason for this behavior? Has anyone else encountered this?

'PerlModule Apache' creates a error when include in httpd.conf-trying to fix 'Apache.pm failed to load' problem
Problem: I configure apache and mod_perl. One day it runs fine. The next day I stop and start the server and get a 'Apache.pm failed' problem. I looked at the web site and found I needed to add ' PerlModule Apache' to my httpd.conf file. I get the error message listed below. I looked at the web site again and made sure that I was performing the 'make' and 'make install' steps for mod_perl. I get the same syntax error. I looked at the 'PerlSetEnv' command and didn't think it was the solution. Does anyone have any ideas? The error message and other details are listed below.

Mod Perl Vhost

RE: [ANNOUNCE] Apache::ProxyRewrite 0.11
Stephane, When you say per-directory realms, do you mean you want to be able to define a ProxyAuthInfo variable multiple times? You can do that once per front-end location. Currently, the ProxyAuthInfo variable is not tied to a particular realm. Rather, it is tied to a particular URI. As for javascript, if it is properly encased within HTML comments, it won't be touched by the rewriting engine. If it dynamically generates URLs on the fly, the likely case is that these URLs will be invalid or will point directly to the backend, skipping the proxy. Two things about this: 1) If your front-end URI space maps directly onto your backend and the javascript produces relative URIs, there shouldn't be a problem unless the code is generating absolute URLs. 2) In order to handle all cases of dynamically rewriting javascript (or any code, for that matter), one must first solve the halting problem. That is an impossible task.

Is mod_perl enabled on your server, ie does $ENV{'MOD_PERL'} exist?
How are you loading mod_perl? As a DSO?
How is mod_perl enabled in your httpd.conf?
What version of mod_perl / Apache are you using? On which OS?
Some more information/config chunks would help to debug your problem.

HTTP_REFERRER and Mod_perl
hello, okay, this may be a silly configuration problem, but I would really like to know if its jst me with this problem. if it is, then i dont mind being hit around the hit and pointed to the appropiate place for further reading. I have setup Apache (1.3.14) to use mod_perl for all the perl scripts (.pl) on the webroot. Everything is working great, I have written my own authentication procedures against postgreSQL 7 and have also used the Apache::DBI. Thats not the problem. The problems arise when i try to use HTTP_REFERRER from the $ENV enviroment. All the other variables are set jst fine (HTTP_HOST, HTTP_ACCEPT, HTTPS) but no HTTP_REFERRER. What am I doing wrong to not 'obtain' this variable. it never shows up in the $ENV list. Is this an oversight of mod_perl (v1.24). I need this to stop people from typing in URLS or jumping to a location from a bookmark. If i cant do it this way, then I guess I will have to use the MD5 encrypted url checksum and do it that way.

Your reference the variable as HTTP_REFERRER when it is actually
HTTP_REFERER (mispelled in the header specs). When I call
$ENV{'HTTP_REFERER'} from a script in my perl-bin it works fine.

RE: Specific limiting examples (was RE: Apache::SizeLimit for unsharedRAM ???)
I think that the problem here is that we've asked for more info and he hasn't supplied it. He's given us generics and as a result has gotten generic answers. I haven't been fishing for a handout of doing the work for me. I've been trying to see what people have done. The reason for the waiting I've done is, I've looked at no less than 7 CPAN modules that do some kind of resource/server monitoring, and I couldn't figure out which one(s) would go together as a reasonable combination. 1) What are the average hits per second that you are projecting this box to handle? Up to, say 3,000,000 hits/aday. 2) What is the peak hits per second that you are project this box to handle? This is a guesstimate, but approx 50/s 3) We know you have a gig of ram, but give us info on the rest of the platform? No, I have 2GB of ram, on a dual PIII/550 BX board, on a 8GB drive 4) What's your OS like? Solaris, AIX, HP-UX, Linux, FreeBSD, etc. which version and/or flavor Running RedHat 6.1 updated w/ all kindsa current pathches/updates. 5) What other processes are you running? predominantly I'm running a Count Daemon on the same box. My project is http://www.exitexchange.com, and I take raw hits at the webserver and fire them over to my count daemon which keeps load down on the Database... but I'm ahead of myself. 6) Do you have a Database? Which one? A gig of ram is nothing to Oracle Oracle 8.1.6 on a Sun 450 (4x400Mhz UltraSparc ### w/ 2GB of Ram, 7x9GB SCSI in a software RAID for the dataspace running Solaris 8) 6a) Will be running queries constantly or will you be caching a lot? Whenever possible, I try to cache alot. The largest part of the application that is NOT cached is the part I'm working on right now... ever heard of POE? 7) What other modules are you running? PhP? SpeedyCGI? Axkit? Cocoon? Well, the count server is only running mod_perl, with a couple of custom server extensions, all pretty lean. Per process is abt 12.5MB, shared is 5600k. In short what is the server DOING at any given moment. Until folks have a feel for this no one is going to be able to offer you any insight beyond what you already have. Well I get a hit, I hit the database for the response, I send it back interpolated into the response content. Currently about 800K times/day. :-) However I got what I was looking for out of this discussion a couple of messages back, with Perrin's example. YES the numbers are made up. No problem... I have a basic syntactic skeleton to work with, now I can fine tune. L8r, Rob
Apache::DBI type functionality but per-request
I tend to write my apps in a modular fashion, so that each module
connects to the database and fetches its data and then disconnects.
Often, a program will require data from several modules resulting in a
lot of wasted connect/disconnect ops. Apache::DBI does solve this
issue, but I don't want nor need to keep lingering connections for a
lightly-used application. (The DB is not used for the majority of
hits to the site.)
I see two possible solutions here:
1) use a cleanup handler to run thru Apache::DBI's connection cache
and disconnect them
2) roll my own.
Right now I've got an implementation of option 1, but I am not sure
how it interacts with auto-rollback from Apache::DBI.
Here's the function from my startup.perl script:
sub My::DBICleanup {
my $connection_href = Apache::DBI::all_handlers();
return unless $connection_href;
foreach my $key (keys %$connection_href) {
delete $connection_href-{$key};
warn "DBIClenaup Purged connection $key\n";
}
}
Apache-push_handlers('PerlCleanupHandler', \My::DBICleanup);
My guess is that my handler will clearnup the cache before
Apache::DBI's handler gets a chance to auto-rollback. Is this some
feature others may want? Perhaps a new feature to Apache::DBI's
cleanup handler might be the way to go?
Any comments?

Re: HTTP_REFERRER and Mod_perl
Are you hitting the page directly? If so then you will not get a referer.
You have to link to it from another page in order for that variable to be
set. If the page is the first to load in the browser there is no referring
page.

RE: HTTP_REFERRER and Mod_perl
Please keep in mind that what you describe is a behaviour of one particular user agent. Some UAs just never send referer for anonymity. (Sometimes proxy will do that for them). Some do it for links from a web page, but not from a file:// URL. Some don't care for the URI scheme, and you get referer's from one's bookmarks on the disk. So, I think, the moral of the story is that basing your site logic on smth that requires particular way of referer tracking is not the best option. You probably want to use some means of session control if you want to make it more standard/portable (there are many ways of doing it - discussed lots of times around here). I agree, however, that if you are aiming at some local community and you are pretty sure about their least common denominator of referer-sending behaviour, the CPU wasted at your server will be less if you check the referer. I personally use referer only for xrefs validation/stats purposes.

Edmund,
I have idea for AuthenDBI.pm. I have not tried to code it yet, however.
The function would come in two parts:
A) Provide an option to keep a count of the number of times a user logs in.
Store this value in DBI field. (Other field may also be considered, see
below.)
B) Provide a directive to perform a comparison on any and all fields of the
user who successfully logged in. If the comparison is true, provide a URL
to REDIRECT the user.
The directives could be something like:
Auth_DBI_logcountusecount
Where usecount is the DBI field name to record the number of times a user
has logged in.
Auth_DBI_compare{regexp}URL
Where regexp is the compare string and where URL is where to REDIRECT the
user. I think that the original URL should be passed as a URL ? argument,
so that the REDIRECT cgi target could determine the original request's URL.
The regexp would have to be able to easily use any arbitrary field values.
Perhaps simply by pre-appending the field name with a '$', for example:
Auth_DBI_compare{$username='xyz' $usecount%2} /cgi/newDBIpasswd.pl
This would run the "/cgi/newDBIpasswd.pl?original-URL" script every other
time for user 'xyz'.
Other additional informational fields that may be considered are:
Auth_DBI_timefieldname
to keep track of when the user last logged in.
Auth_DBI_rejectfieldname
to keep track of the number of bad log in attempts.
What do you think?
What did you think of my AuthzDBI.pm, "set field environment variable"
hack, that sent you yesterday?
Confusion between script in mod_perl (fwd)
I am using Registry with mod_perl and virtual host.
Some time my scripts get confuse.
If I do a stack backtrace,
For example:
/usr/local/website/caisses/cgi-bin/caisses:1:SedNove::xml,
/usr/local/website/sednove/cgi-bin/nf,1079,SedNove::xml::raise,10,
2:SedNove::oper,
/usr/local/website/sednove/cgi-bin/nf,2943,SedNove::xml::xmlread,1,0,,,0,
As you can see the program is going from one script to the other one
without any reason.
I have a startup file that look like:
$ENV{GATEWAY_INTERFACE} =~ /^CGI-Perl/ or die "GATEWAY_INTERFACE not Perl!";
use Apache::Registry (); # for things in the "/programs" URL
# pull in things we will use in most requests so it is read and compiled
# exactly once
use CGI (); CGI-compile(':all');
use CGI::Carp ();
use DB_File;
The version of my program are:
Apache/1.3.12 (Unix) mod_perl/1.24
Any Idea why its doing that?

Re: Apache::DBI type functionality but per-request
On Mon, 15 Jan 2001, Vivek Khera wrote:
I tend to write my apps in a modular fashion, so that each module
connects to the database and fetches its data and then disconnects.
Often, a program will require data from several modules resulting in a
lot of wasted connect/disconnect ops. Apache::DBI does solve this
issue, but I don't want nor need to keep lingering connections for a
lightly-used application. (The DB is not used for the majority of
hits to the site.)
I use a singleton for the database connection:
sub get_dbh {
my $dbh = Apache-request()-pnotes('dbh');
if (!$dbh) {
$dbh = _new_database_connection();
Apache-request()-pnotes('dbh', $dbh);
}
return $dbh;
}
Using pnotes is better than using a global, because mod_perl will make
sure it gets cleaned up after the request even if something goes wrong.
You can use Apache::DBI with this or not, without changing the code.
My guess is that my handler will clearnup the cache before
Apache::DBI's handler gets a chance to auto-rollback.
You might get some errors about undefined methods and such from that.

setting lib for mod_perl installation
I just moved from dedicated to virtual hosting sigh, and was wondering how to configure mod_perl to install the modules to a private lib, outside of @INC.

Re: Looking for a new distro
Jamie, I'm sorry you are having problems with it. I am running it here and it's fine. I used Apache Toolbox to install it though, which you will probably want to take a look at for future reference. The site is at www.apachetoolbox.com. It will install Apache and most of the major mod's from source. It's easy to compile and then all you have to do is adjust the conf files.

DBIx::Easy
Has any one used DBIx::Easy under mod_perl? I wrote the author and he indicated that someone had reported a memory leak under mod_perl which they said has been fixed, but not released. I am curious if anyone else has had exprience with this module and if they have used it in conjunction with Apache::DBI. Should it work seamlessly or does it need to be overridden to work correctly with it? Aaron Johnson
Redirecting a multipart/form-data POST request
I am writing a program that needs to process form data, (here's
the kicker) which is sometimes multipart/form-data, then
redirect a user to a GET request (which doesn't need to process
the form data). I would like to use the standard mechanism for
issuing a redirect, for other reasons:
$r-header_out('Location' = $url);
return REDIRECT;
I have discovered two ways to achieve redirects from a POST
request if its content is application/x-www-form-urlencoded:
- $r-print() the headers manually and have the handler return
DONE or HTTP_OK. This nasty hack is what I am doing at this
time so I can get redirects from multipart/form-data to
somehow work.
- convert the POST request to a GET and redirect the standard
way. I don't understand why forcing a read of all the data
coming in from the HTTP request allows redirects to work, but
it does.
When I do neither, i.e., leave the POST request as is and use
the standard redirect mechanism, the browser hangs and the
server actually does not send the redirect until I hit the Stop
button (I'm using ngrep to determine this). This also happens
if I use the $r-print($header) method and still return
REDIRECT.
The second method allows me to revert to the use of the default
redirect mechanism, but unfortunately does not work with
multipart/form-data. I would *really* like to be able to use
the standard redirection mechanism for other reasons. From the
Apache man page:
$r-content
The $r-content method will return the entity body
read from the client, but only if the request content
type is `application/x-www-form-urlencoded'.
...
Is there a similar technique I can use to read all the
multipart/form-data from the socket and then allow CGI.pm to
continue to process it, and would this work?
Thank you,
Darren

Then you can get on to really hard things, like scaling your database. In my experience setting MaxClients for the mod_perl httpd really really low (may be as low as 5-10 childs) and letting your mod_proxy deal with hundreds of clients works great. It all depends though; in my application I pretty much don't have anything blocking, so I couldn't get much more done with more childs. If most of your time to serve a request is spend waiting for the database you will maybe want more childs going. - ask -- ask bjoern hansen - http://ask.netcetera.dk/ more than 70M impressions per day, http://valueclick.com

Try adding
$r-method('GET');
$r-headers_in-unset('Content-length');
to your code before doing the return REDIRECT.

Re: ANNOUNCE: TPC5: mod_perl track: Call For Papers
Hi Stas, Ok, the CFP is officially out, let those proposals come in: All the details can be found here: http://perl.apache.org/conferences/tpc5-us/cfp.html I didn't found a link from anywhere to that page. I don't think it was your intention to hide that page. Shouldn't at least on http://perl.apache.org and on http://conferences.oreilly.com/perl5/ a link point the people, who wants to submit something mod_perl related, to that page ? I guess the intention was that _all_ mod_perl related things are submitted to email there and not to the official tpc5 address, is this right? Gerald Notice that while our cfp resembles the general CFP http://conferences.oreilly.com/perl5/ it's not the same, so don't confuse the two. Ours has the magic mod_perl token on the top :) I think I've summarized the last CFP thread into a pretty long wishlist of topics. If something is missing and you think it's relevant to mod_perl and interesting to the hear about submit as well. Thank you for your support!

It also catches situations where you occasionally do something that raises the size of a process significantly by killing those off sooner. - Perrin
