perl.com: Testing mod_perl 2.0
for those who haven't already seen it, perl.com ran the second of my series of articles on mod_perl 2.0 late last week. the title is actually a bit decieving. it's about using the Apache-Test testing framework, but although Apache-Test is shown in a mod_perl 2.0 context, Apache-Test can be used with mod_perl 1.0 as well - many of the illustrations are cross platform. the code from the article can be downloaded from http://www.modperlcookbook.org/~geoff/perl.com/Apache-Clean-2.0.tar.gz or, for the mod_perl 1.0 version, http://www.modperlcookbook.org/~geoff/perl.com/Apache-Clean-1.0.tar.gz if you're interested in trying it out. enjoy --Geoff In our continuing mod_perl 2.0 series, Geoff Young looks at the new testing scheme, Apache-Test, and how it fits in with your mod_perl programs. http://www.perl.com/pub/a/2003/05/22/testing.html

[mp2] httpd.conf Perl block problems
I've got a working Apache::ASP application that has been used mainly on more-or-less stock Red Hat Linux 7.2 and 7.3 systems (Apache 1.3.2x, mod_perl 1.26, perl 5.6.1). I tried moving it to a Red Hat Linux 9 system (Apache 2.0.40, mod_perl 1.99_07, perl 5.8.0) and it failed. The bugs I'm seeing are tickled by the Perl block I've been using in httpd.conf on the RH7 systems. This block contains an Apache::ASP-Loader() directive, which precompiles all of the scripts before the httpd children are forked off, for efficiency. If I comment this optional Perl block out, httpd starts up fine. The first bug is a known one: apparently, recent mod_perls are sensitive to the syntax of the Perl tag: they require a space in it, like this: Perl I hope this is just a bug that hasn't risen to the top of the priority list yet, and that the mod_perl folk don't intend to keep this sytax. Once that was fixed, I found a new problem. I recieved errors like this: Syntax error on line 1059 of /etc/httpd/conf/httpd.conf: Bareword Apache::OK not allowed while strict subs in use at /usr/lib/perl5/site_perl/5.8.0//i386-linux-thread-multi/Apache/PerlSection.pm line 47.!BEGIN not safe after errors--compilation aborted at /usr/lib/perl5/site_perl/5.8.0//i386-linux-thread-multi/Apache/PerlSection.pm line 58.!Compilation failed in require at (eval 57) line 3.! Line 1059 is the /Perl line. If I comment out the use strict directive at the top of PerlSection.pm, this problem goes away. I'm not sure what the correct fix is, but I hope this is enough information to lead one of the mod_perl developers to a solution. I replaced the mod_perl Red Hat shippped with v1.99_09 while chasing this problem, so that's the version I changed.

Apache Error of $r-read failed to read
Hi, We have been having some problems where all of a sudden apache will start logging the error of: [error] mod_perl: $r-read failed to read Multiple times (100s in less then 10th ofa sec), often it will get to the point where load on the machine goes through the roof and apache has problems responding and it appears to be the number of requests that are happening as limits that shouldn't be reached like DB connections and apache processes are maxing out during non-peak hours. From what we could see it looked like someone outside was sending all kind of linefeeds and whatnot within the URL which was documented in the Apache 45 release which we did update - now we are down to getting the above mod_perl error and shortly after that starts all hell breaks loose. Nowhere in our code do we directly call the "read" method nor can I find anything relating to the error so I'm a little lost on what I can do. Any ideas?

[mp1] .htaccess and mod_perl
I am stuck in an Ensim environment (shared web-hosting, Apache 1.3.27 and mod_perl 1.24) and am trying to get around some of the limitations imposed by Ensim. Basically, I have complete .htaccess control but have no way to restart the server or start it with different arguments or modify the central httpd.conf What is possible within an .htaccess file as far as perl configuration for mod_perl 1? I am already using the Perl/Perl sections to unshift @INC (because 'PerlSetVar PERL5LIB /my/path' pushes the values) and have tried using PerlRequire startup.pl, however the startup.pl file only executes for one of the httpd children. What happens with PerlModule directives, i.e. does the module get loaded only once, the first time that apache processes the .htaccess, or every time apache hits the directory? Similarly, If I am developing a module in place and PerlModule it within an .htaccess, will it be reloaded whenever apache hits the directory, or only once? If its only once, can I force a reload of the module? Finally, can I use the Perl/Perl sections to totally replace a startup.pl, or are there any caveats that I should be aware of? Thanks -Mike

ugh.
What is possible within an .htaccess file as far as perl configuration
for mod_perl 1?
just about anything. I use an Ensim installation, and am constantly
frustrated by it. however, there are ways around just about anything. for
instance, I couldn't install an ErrorDocument in a .htaccess file for some
reason. fine, I just used
PerlInitHandler 'sub { shift-custom_response(404, /notfound.html); return 0}'
and problem solved :) you can use this approach for just about anything -
I've also use $r-handler('default-handler') to force .cgi documents to be
un-executed and shown as plain text (useful for code examples :). and it
doesn't need to be from an anonymous sub either.
What happens with
PerlModule directives, i.e. does the module get loaded only once, the
first time that apache processes the .htaccess, or every time apache
hits the directory?
it probably won't matter - like use(), perl will only use() the module once.
Similarly, If I am developing a module in place and
PerlModule it within an .htaccess, will it be reloaded whenever apache
hits the directory, or only once?
modules are only loaded once - the first time they are use()d per-child (or
at server init)
If its only once, can I force a
reload of the module?
use
PerlInitHandler Apache::StatINC
to reload them during development (I've also used this on ensim :)

Large Data Set In Mod_Perl
Hi All, For one of the websites i have developed (/am developing), i have a dataset that i must refer to for some of the dynamic pages. The data is planetary data that is pretty much in spreadsheet format, aka, i have just under 800,000 rows of data. I don't do any copmlex searches or functions on the data. I simply need to look at certain columns at certain times. sample data set: planet |date| right_ascension | declination | distance | altitude | azimuth | visibility -++-+-+--+--+--+ jupiter | 1900-01-01 | 15h 57m 7s | -19° 37.2' |6.108 | 10.199 | 39.263 | up mars| 1900-01-01 | 19h 2m 20s | -23° 36.7' |2.401 | 14.764 |-4.65 | up mercury | 1900-01-01 | 17h 15m 16s | -21° 59.7' |1.151 | 14.041 | 20.846 | up moon| 1900-01-01 | 18h 41m 17s | -21° 21.8' | 58.2 | 17.136 |0.343 | transit neptune | 1900-01-01 | 5h 39m 18s | +22° 4.0' | 28.922 | -15.128 | -164.799 | set I need to be able to say: * Lookup the _distance_ for the planet _mercury_ on the date _1900-01-01_ Currently i do this using a postgres database, however, my question is, is there a quicker way to do this in mod_perl - would a DB_File or some other structure be better? I would be interested in knowing if others have dealt with large data sets as above and what solutions they have used. A DB is quick, but is there something one can use in mod_perl that would be quicker? perhaps something such as copying the whole 800,000 rows to memory (as a hash?) on apache startup? simran.

What you can do is build a key out of planet + date, so that you grab the right record with a single access. Either use MLDBM for storing hashes inside each record, or just a simple join/split approach. MySQL would probably also be faster than PostgreSQL for this kind of simple read-only querying, but not as fast as a DBM file. SDBM_File is the fastest DBM around, if you can live with the space limitations it has. perhaps something such as copying the whole 800,000 rows to memory (as a hash?) on apache startup? That would be the fastest by far, but it will use a boatload of RAM. It's pretty easy to try, so test it and see if you can spare the RAM it requires. - Perrin
Re: Large Data Set In Mod_Perl
I've dealt with fairly large sets, but not as static as yours. If your only
keys for searching are planet and date, then a perl lookup with a hash will
be faster overall since a DB lookup involves connecting to the database,
doing the standard prepare/execute/fetch which could be as costly (for a
single lookup) as the lookup itself. The actual lookup of the record in the
database is probably as fast or faster than Perl (especially after the
initial lookup that primes the caches) if you have indexed the columns on
the table properly.
If you are planning to do lots of lookups on this dataset, preloading the
dataset in a perl hash would definitely be the better approach. If you are
doing only a few lookups over a given period, it may or may not be worth it
and taking up lots of memory for no reason and sticking with the db lookup
would probably be best.
For the perl hash, I would key the hash on the combo of planet and date,
something like:
my %Planets = (
jupiter= {
1900-01-01= ( 5h 39m 18s, +22o
4.0', 28.922, -15,128, -164.799, set),
1900-01-02= ( 5h 39m 18s, +22o
4.0', 28.922, -15,128, -164.799, set),
},
neptune= {
1900-01-01= ( 5h 39m 18s, +22o
4.0', 28.922, -15,128, -164.799, set),
1900-01-02= ( 5h 39m 18s, +22o
4.0', 28.922, -15,128, -164.799, set),
},
) ;
You could also just combine the planet and date as the string for the hash
key like jupiter1900-01-01 but not real sure if this buys you any
performance - it might even be slightly slower since its working on a much
larger single hash rather than a two dimensional hash - might be interesting
to benchmark it on your size dataset to see what really happens. As to
using DB_file, it would probably be somewhere between the Perl hash approach
and using the standard SQL database interface.

Subject: Large Data Set In Mod_Perl
Hi All,
For one of the websites i have developed (/am developing), i have a
dataset that i must refer to for some of the dynamic pages.
The data is planetary data that is pretty much in spreadsheet format,
aka, i have just under 800,000 rows of data. I don't do any copmlex
searches or functions on the data. I simply need to look at certain
columns at certain times.
sample data set:
planet |date| right_ascension | declination | distance |
altitude | azimuth | visibility
-++-+-+--+
--+--+
jupiter | 1900-01-01 | 15h 57m 7s | -19° 37.2' |6.108 |
10.199 | 39.263 | up
mars| 1900-01-01 | 19h 2m 20s | -23° 36.7' |2.401 |
14.764 |-4.65 | up
mercury | 1900-01-01 | 17h 15m 16s | -21° 59.7' |1.151 |
14.041 | 20.846 | up
moon| 1900-01-01 | 18h 41m 17s | -21° 21.8' | 58.2 |
17.136 |0.343 | transit
neptune | 1900-01-01 | 5h 39m 18s | +22° 4.0' | 28.922
-15.128 | -164.799 | set
I need to be able to say:
* Lookup the _distance_ for the planet _mercury_ on the date _1900-01-01_
Currently i do this using a postgres database, however, my question is,
is there a quicker way to do this in mod_perl - would a DB_File or some
other structure be better?
I would be interested in knowing if others have dealt with large data
sets as above and what solutions they have used.
A DB is quick, but is there something one can use in mod_perl that would
be quicker? perhaps something such as copying the whole 800,000 rows to
memory (as a hash?) on apache startup?

[mp2] a better way to block/throttle clients
mod_perl 1.0 has several tools for throttling/block clients, but they all do
their work in pretty late stage, wasting quite a few resources. With mp2 you
can now throttle/block clients before any data was sent and before Apache has
done anything at all. This example module takes advantage of running during
the pre_connection phase. I believe this is almost as efficient as firewall
blocking (the only overhead is select() and several calls in perl). the cool
thing is that Apache simply drops the connection without sending anything back
to the client ;)
Of course you want to adopt it to use a real database and some well defined
blocking policies. May be Randal will revise his webtechnique column to use
this better phase (CC'ing him).
#file:MyApache/BlockIP2.pm

package MyApache::BlockIP2;
use Apache::Connection ();
use Apache::Const -compile = qw(FORBIDDEN OK);

my Apache::Connection $c = shift;
my $ip = $c-remote_ip;

warn IP $ip is blocked\n;
return Apache::FORBIDDEN;
}

You will need mp 1.99_08 or higher for this to work.

Hi all, I have the following problem. I designed a mod_perl handler module that parses a certain XML-like language into Virtual Reality Modeling Language (VRML) and sends it to the browser. It works fine first time, but when I refresh it, it works differently. It feels like the module does not create a new VRML on refresh but adds a newone to the previous, the result being crooked and twisted. Similar thing happens when I activate url in VRML file, calling handler again from inside the roduced VRML. Hope you understand what I mean. My theory is that something is wrong with local/global variables in the module. Any hints? Dr. Igor Rojdestvenski,Dept.

RE: Can't use sendmail more than once
That's fixed it - I don't server many images - thanks very much! -Original Message- From: Perrin Harkins [mailto:[EMAIL PROTECTED] Sent: Thursday, 29 May 2003 1:07 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Re: Can't use sendmail more than once On Wed, 2003-05-28 at 22:45, Greg Dutkowski wrote: I have migrated my site from IIS and Active State to Apache 1.3 and mod_perl on a Windows machine. I use the site to send emails to registered users using Mail::sendmail through our SMTP server (another machine). With Apache I can only send emails once after I start the Apache server, thereafter it tells me it can't connect to the SMTP server. Restarting the Apache server leads to again being able to only send emails once. Any ideas? This is a known problem with mod_perl 1.x on Win32. Sockets only work when you make it single-threaded (ThreadsPerChild 1). Doing that doesn't make a difference in terms of your actual script performance, since mod_perl is already single-threaded on Win32, but it will make images slow. One solution is to serve the images from a separate web server. - Perrin
