mod_perl and 700k+ files?
Hey there, wondering if anyone could help me with this. I'm relatively new to mod_perl... I've got a 700k file that is loaded each time I run a CGI script, so I'm hoping to cache the file using mod_perl somehow. The file will change occasionally (maybe once a week) - the reload of a few seconds isn't worrisome, but it has to be done without restarting the server. Any suggestions on exactly the best way to do this? I've going to: - PerlSetupEnv Off - PerlModule and PerlRequre - Remove buffering. - Cache from XML::Simple ** ** The 700k file is an XML file, read in by XML::Simple. XML::Simple can cache that file into memory. Is this how I should do it? Or should I load the file from my startup.pl script so that the file is shared amongst all the apache children? If that's the case, how would I dynamically reload it? Morbus Iff .sig on other machine. http://www.disobey.com/ http://www.gamegrene.com/

Re: mod_perl and 700k files...
The above code asigns a signal handler for the USR2 signal. This signal has been chosen because it's least likely to be used by the other parts of the server. That, unfortunately doesn't tell me what causes a USR2 signal to be sent to Apache. Or when it's caused. I only want to reload the file when said file has changed. Am I supposed to do some checking against the file -M time myself, and then send a USR2 signal myself? You didn't search the guide, even if you try to make everyone believe that Sigh. What the frel is your problem, binky? talking about using USR2, not the caching technique). The first hit in the http://thingy.kcilink.com/modperlguide/debug/Using_the_Perl_Trace.html Actually, no, not really. That's the same exact page I got when I didn't search the search engine (thus pulling the wool over your elite mod_perl eyes) before. Strangely, enough, the same quoted sentence in my email, is golly gosh darn, the second sentence on that page. And my comments to that page still apply. I will agree, in some sense, however, that my comments about not tell[ing] me what causes a USR2 signal are incorrect. I was looking for a solution in all perl, so when I saw the kill command, I just stopped reading, since it wasn't what I'm looking for. http://perl.apache.org/guide/porting.html#Configuration_Files_Writing_Dy http://perl.apache.org/guide/porting.html#Using_Apache_Reload The first was more helpful than the second (ignorantly speaking). The thing that worries me the most is about the 700k file being passed around to all the children during a ::Reload or other solution. More specifically, is there anyway to reload a file into the parent, which would automatically be shared with existing children, and all newly spawned children? Without restarting the server?

Any particular reasons why any of these may not play with with mod_perl/Mason? Well, I wrote Alzabo and it plays just fine with mod_perl and Mason. In fact, the schema creation interface is a set of Mason components. The caching/syncing architecture was specifically created to allow syncing of objects between multiple processes (ala mod_perl) and I will be creating a syncing module sometime that sync between multiple machines as well. I think the author of SPOPS is also a mod_perl user (I'm pretty sure he's posted to the mod_perl list in the past) so I'd expect it to play nice. Tangram I don't know much about in relation to mod_perl. However, these are all fairly different systems. I often descrive Alzabo as the opposite of Tangram, for instance. Alzabo is an RDBMS-OO mapper and Tangram is an OO-RDBMS mapper. Tangram is aimed at letting you have transparent OO persistence in an RDBMS without worrying about the schema too much. Alzabo is about taking an RDBMS and giving you access to it through convenient object methods. I'm not sure exactly what the goal of SPOPS is, so I'll let the author speak for himself. -dave /*== www.urth.org We await the New Sun ==*/

In this case it just means that 'make' has noticed something odd about the various dates and times in your system. It is very important for several reasons that you keep the computer clock as accurate as you can. There are free utilities such as 'ntpd' to help you to do that. One reason for needing an accurate clock is that the 'make' utility uses the time and date information which your system keeps about its files to decide whether or not to recompile (or whatever other action may be necessary for a 'target'). Another reason is that when a machine is used to serve Web content the 'latest modification' stamps on files are used to decide whether or not it is necessary to download fresh copies of the files to the client. Your system seems to have confusing information about the datestamps on files or about the system time itself. If a file was copied when the system time was wrong, and the system time was subsequently corrected, then this error could appear. If the system time is wrong and a file appears to have a date/time later than the current system time, the same problem can appear.

avoiding authentication w/ mod_perl
Hi, I am running a hosting service, and I use mod_perl to filter pages and add banners. For my paid users, I would like to offer the option of using .htaccess files for password protection, but I can't afford to check these files on every hit, only hits to paid sites. I can determine if the user is paid with a couple of lines of perl, but I don't know how to get apache to only authenticate in those cases, and otherwise to ignore the existence of .htaccess files. Does any mod_perl guru out there have some insight on this?

For the record, however, I'm not the clueless newbie, I did RTFM (although, as admitted in another post, skipped the explanation of triggering the USR2 signal due to it being related to 'kill' and not a perl solution), and was only impolite after the golden rule came into effect.

I had to deal with this all the time when I used a NetApp Filer with an old firmware that didn't support ntp.. -- Paul Lindner [EMAIL PROTECTED]
Re: avoiding authentication w/ mod_perl
Hi ( 01.05.10 13:07 -0600 ) Mark Holt: For my paid users, I would like to offer the option of using .htaccess files for password protection, but I can't afford to check these files on every hit, only hits to paid sites. I can determine if the user is paid with a couple of lines of perl, but I don't know how to get apache to only authenticate in those cases, and otherwise to ignore the existence of .htaccess files. What comes to mind is a handler for these locations. The handler runs the few lines of perl to determine if the user is paid, then can call another handler [or subroutine] if the .htaccess should get read and parsed. Also, usually authentication/authorization happens much earlier in Apache response cycle, so you may need to use redirects or custom 'Access Denied' pages to get the effect you want. There may be other ways to do this, and I'm only guessing at what effect you want. Good luck. -- \js For the record, pot, like the _Reader's Digest_, is not necessarily habit- forming, but both can lead to hard-core addiction: heroin, in one case, abridged bad books in the other.

Where exactly is the Perl interpreter?
I was just wondering- where exactly is the Perl interpreter in mod_perl 1.25 (for Apache 1.3) and where will it be in mod_perl 2 (Apache 2.0)?

looking for a functin to move %fdat to the symbol table..
php has a function called extract which takes an array (no distinction between arrays and hashes in php. in this case in perl, it'd actually be a hash). extract takes the key values of the array (and optionally prepends a user specified prefix to each of the values to avoid clobbering other values in the symbol table), sets each of them up as a variable with that name and sets the variable's value equal to the value of that associated key in the hash. the beauty of extract comes into play when you want to use each of the key/value pairs in the array. instead of setting them up one at a time, pass the array to extract and voila, you have all of the key/value elements available as variables. if my description is too unclear, you can check the extract functions info at http://www.php.net/manual/en/function.extract.php. does embedded perl sport a similar function? my apologies if i've posted to the wrong list. i did cross post to the embperl list, to cover all of the bases. :: jason n perkins :: email - [EMAIL PROTECTED] :: web - www.somebodydial911.com

Hi,
As part of my ongoing effort to streamline my mod_perl apps, I've come
to discover the joy of constant subroutines and perl's ability to
inline or eliminate code at compile time. I have a solution that
works, but would be interested in seeing if others had better
syntactic sugar.. Anyway:
We have a module CP::Util, with this begin block:
BEGIN {
$ENV{CP_DEBUG} ||= 0;
if ($ENV{CP_DEBUG} == 1) {
*{CP::Util::DBG} = sub () {1;};
} else {
*{CP::Util::DBG} = sub () {0;};
}
}
@EXPORT_OK = qw(DBG);
Then, in another module I do:
use CP::Util qw(DBG);
DBG debug('whoa there boy');
The end result is, when CP_DEBUG=1, the code is in there. When
CP_DEBUG=0, the code is trimmed out at compile time (because DBG is a
constant subroutine, see perldoc perlsub for more info)
This is a real win compared to our old way of using a subroutine
called debug that did a no-op. Consider:
debug 'whoa there' . $foo . join(keys(%bar));
The args to debug are still computed, passed on the stack, etc..
Now, my question is: Is there some trick I could use to retain the simple syntax:
debug foo bar;
it is possible, and has been on the optimizations slide for the 2.0
talks i've been giving. one idea i had in mind was:
$r-log-debug(...);
would be nulled out unless LogLevel is configured to debug.
i have fiddled with it, you can try this:

see test.pl for the examples.
i'm open to names/interface changes, the module is just a
proof-of-concept.

8-bit characters and mod_perl/Apache-ASP
Im having an odd (and annoying) problem with text data being returned via
Oracle::DBD (10.7) to an Apache::ASP (2.09) script. Essentially, perl that
returns perfectly valid characters in both cgi and as a .pl file fails to
return valid characters in the context of an Apache::ASP file. The issue,
I think has to do with the fact that the Oracle database (8.0.6) is
returning 8-bit characters. I can confirm this because I can repoint my
application to a version of the database set with 7bit characters and
everything works. While this shouldnt really be a problem (and isnt in the
normal 'perl' setting), Apache::ASP/mod_perl seems to be barfing on these
characters.
Here's some sample code:
use PNAP::Database::Query; ## a simplified database connection module
use CGI qw/:standard/; ## for CGI output
print header,
start_html('A Simple Example'),
## make a database connection
my $dbconn= new PNAP::Database::Query(Connection=NSPFinance, Debug=0);
## the sql statementA
my $orgSQL = select o.FULLNAME;
$orgSQL .= from ORGANIZATION o, PARTY_ROLE pr, PARTY_ROLE_TYPE prt;
$orgSQL .= where o.ORGANIZATIONOID = pr.SubjectPartyOID and;
$orgSQL .= pr.PartyRoleTypeOID = prt.PartyRoleTypeOID and prt.ShortName =
'NSP' and;
$orgSQL .= pr.StartDate = sysdate and (pr.EndDate is null or pr.EndDate
sysdate);
$orgSQL .= order by FULLNAME;
my $rs = $dbconn-query(Sql=$orgSQL, UseCursor=0);
if ($rs)
{
while ($rs-next())
{
my $fullname = $rs-FULLNAME; ## get the value from therecordset
print Fullname: , $fullname,BR\n; ## output the value
}
$dbconn-finish($rs);
}
What is odd is that if I run this as a cgi (or from the command line), I
get this output:
Fullname: ATT
Fullname: Agis
Fullname: At Home
Fullname: CW
Fullname: CW/IDC
Fullname: Digex
Fullname: EBONE
...
However, the exact same code run as an Apache::ASP page results in this
output (on netscape for linux 4.76).
Fullname:
Fullname:
Fullname:
Fullname:
Fullname:

On IE, however, I get this as output (viewed as source):

Fullname: A g i s
Fullname: A t H o m e
Fullname: C W
Fullname: C W / I D C
Fullname: D i g e x
Fullname: E B O N E
...
This implies that the 8-bit characters are being rendered/dealt with
*differently* for the cgi version and the Apache::ASP version (and that
the Apache::ASP version honks up the 8-bit characters somehow). IE seems
to deal with the odd characters better than netscape.
In order to address this problem, Ive tried all the standard approaches to
dealing with 8bit characters and Oracle databases (setting NLS_LANG, etc)
and have tried using Convert::Translit module to do the conversion..
However, none of those actions seem to make any difference. I still get
wonky output with the mod_perl/Apache::ASP version (but not the normal
Perl/cgi version).
What I am wondering is:
(1) is there a known problem with mod_perl and 8-bit character
sets? The version of apache I am running is 1.3.19 and mod perl 1.25, and
Apache 2.09.
(2) Is there any problem with this from the Apache::ASP side in either the
way the Response-Write is done or the way in which these character sets
are handled? Ive looked at the Response-Write and Response-WriteRef but
dont see anything obvious that could cause this.

Re: 8-bit characters and mod_perl/Apache-ASP
Difference like this, where cgi perl scripts work fine, but mod_perl/ASP
doesn't, often has to do with %ENV where mod_perl is concerned.
This is because Apache clears %ENV. The best way I have found to know
what is in your %ENV for Oracle connections is to explicitly set it
before the connect like:
$ENV{'ORACLE_HOME'} = '/path/to/oracle/home';
$ENV{'NLS_LANG'} ='american_america.WE8ISO8859P1';
$ENV{'ORA_NLS33'} = $ENV{ORACLE_HOME}.'/ocommon/nls/admin/data';
DBI-connect('dbi:Oracle:' ...);
This likely has nothing to do with Apache::ASP
You can also try PerlPassEnv PerlSetEnv for things like the
above, but explicitly setting has always given me the most mileage.

perl-based authentication
OK, let me be more specific. Here is the problem I face: Hosting of (potentially) millions of websites in a single framework. Clients are not given their own VirtualHost tag in the config file (there are too many), but instead their document root is derived from their hostname. Clients can fluctuate between free and paid users. A mod_perl filter script currently inserts a banner on each HTML page or does nothing, for free and paid users, respectively. Now we want to add Basic HTTP authentication to our paid service. We want to do this using .htaccess files, since this is the method supported by Microsoft FrontPage and improved mod_frontpage on UNIX. This is impossible to do for everyone, since we would take a serious performance loss checking for .htaccess files in the entire directory tree on every hit. I have written some code that will interpret a simple require valid-user statement, parse the indicated password file, and grant or deny access. I added this to the filter script and it works fine, and is only executed when the website is a paid one. The problem with this is I'm realizing how complex the .htaccess-based authentication scheme is, and I don't feel like coding the rest of it when it's already done. I want a mod_perl solution to enable .htaccess authentication in the case of a paid user. There is no trivial (i.e. standard apache) way to tell whether a user is paid, it takes a couple of lines of perl code (let's say a file stat or DB lookup). Now to my question: Is it possible, using mod_perl, to activate Apache's standard .htaccess-based authentication scheme on a per-hit basis, based on the results of perl code to determine whether the user is a paying one? Will this solution avoid checking for the existence of .htaccess files on every hit that is not a paid one? If so, how is this to be done? (Please give code or at least pseudocode where possible.)

You do know about the built-in Perl function 'each', right?
As others have pointed out, what you're asking for can be done, but it
shouldn't be done. You can almost always write much much cleaner code
by dealing with the hashes as hashes and not converting all its parts to
individual scalar variables. I've seen a lot of [bad] code like this:
$name = $data{name};
$address = $data{address};
$phone = $data{phone};
$dbh-do(UPDATE users SET address='$address', phone='$phone'
WHERE name='$name');
It's much better (shorter, faster, safer) to let the hash do the work:
$dbh-do(UPDATE users SET address=?, phone=? WHERE name=?, undef,
@data{'address','phone','name'});
In addition, in a mod_perl environment you don't want any of your
data-carrying variables to be in the runtime symbol table. Lexical
variables ('my') are much safer and guard against variables leaking out
of the scope you thought they were supposed to be in.

If I wrote my own PerlAuthHandler, could it then choose whether to pass through
to the standard AuthHandler?
.htaccess is not used only for auth!!! it's used for adding per-directory

Yes I was envisioning something along these lines in the config file:
Perl
#code to determine paid status
if ($paid) { $AllowOverride = AuthConfig }
/Perl
Or something like that. Not being a mod_perl guru I don't know the syntax, but
I wondered if a construct like this would work on a per-hit basis, or if not, if
someone knew a better one.
So your second question has nothing to do with the first one :)
You're right. one dealing with feasibility of checking for .htaccess files based
on perl code, and one with scalability--not checking for .htaccess files when
not necessary.
You can specify the Auth data in your httpd.conf and avoid creating
.htaccess, saving processing time, but making it harder to maintain
(requires server restart for each modification, whereas .htaccess allows
to do 'hot' modifications without restarting the server.
That is not feasible, because if we can't even afford to put a VirtualHost tag
in for every user, how much less could we afford auth data and server restarts?
But you may be on the right track. Can we use perl code in the global config
file to control auth? I just want a way to activate the standard auth handler
per-hit. It has to be possible in mod_perl. Someone out there has to be wizard
enough to know how. Hopefully that person will be reading this soon.

to challenge the client with basic auth or not unless you use .htaccess.
If I wrote my own PerlAuthHandler, could it then choose whether to pass through
to the standard AuthHandler?
.htaccess is not used only for auth!!! it's used for adding per-directory
extra configuration (usually to override the defaults).
Yes I was envisioning something along these lines in the config file:
Perl
#code to determine paid status
if ($paid) { $AllowOverride = AuthConfig }
/Perl
Or something like that. Not being a mod_perl guru I don't know the syntax, but
I wondered if a construct like this would work on a per-hit basis, or if not, if
someone knew a better one.
So your second question has nothing to do with the first one :)
You're right. one dealing with feasibility of checking for .htaccess files based
on perl code, and one with scalability--not checking for .htaccess files when
not necessary.
You can specify the Auth data in your httpd.conf and avoid creating
.htaccess, saving processing time, but making it harder to maintain
(requires server restart for each modification, whereas .htaccess allows
to do 'hot' modifications without restarting the server.
That is not feasible, because if we can't even afford to put a VirtualHost tag
in for every user, how much less could we afford auth data and server restarts?
But you may be on the right track. Can we use perl code in the global config
file to control auth? I just want a way to activate the standard auth handler
per-hit. It has to be possible in mod_perl. Someone out there has to be wizard
enough to know how. Hopefully that person will be reading this soon.
Thanks,

Re: perl-based authentication
parsing the .htaccess files is what I'm trying to avoid. I want the standard apache module to do that. I just want to control *when*.
