mod_perl and sybase support statically linked into httpd?
Hi, I am currently running Apache on a HP-UX 11 platform, using plain CGIs for dynamic page creation accessing a Sybase database. I have only quite old Sybase client libraries here, forcing me to statically link sybase support into my perl binary. Now I want to switch to mod_perl; the problem is, I have not yet managed to statically compile mod_perl AND sybase support into my httpd. Has anyone on this list already solved this problem? Are there any links on that problem? Any help would be appreciated. | | | knipp | Knipp Medien und Kommunikation GmbH --- Technologiepark Martin-Schmeisser-Weg 9 D-44227 Dortmund Thomas Corte Fon: 0231-9703-0 [EMAIL PROTECTED] Fax: 0231-9703-200
Stumped: Location ignored
Hi,
I hit this months ago but never really solved it... I'm working with the
WING e-mail package by Malcolm Beattie. In my httpd.conf I have tried:
PerlModule Wing_miranda_herrera_iphil_net::Balance
Location /
SetHandler perl-script
PerlHandler Wing_miranda_herrera_iphil_net::Balance
/Location
Perl
and:
$Location{"/"} = {
SetHandler = "perl-script";
PerlHandler = "Wing_miranda_herrera_iphil_net::Balance";
};
/Perl
Neither of these work. When I access /, the module is not invoked, and
instead, Apache brings up the DocumentRoot.
How can I debug why Apache would choose to ignore the Location? Just to
be sure I also tried it with Directory but without luck.
Apache 1.3.9, mod_perl 1.2.1.
(For those working with Wing already, I changed the names of the modules
since I am doing "virtual hosting" with it.)
Thanks!

Re: mod_sandwich - parsing the header and footer through SSI module
Does anyone has a modified version of the Sandwich module that passes the header and footer files through the SSI handler ? the version I've download does it only for the body of the document. The point of Apache::Sandwich is to append a preset header/footer to all HTML (or whatnot) files. If you wanted your own header footer via SSI, it defeats the purpose since you would have to include those in potentially a lot of files. If you're talking about including SSI in the actual headers/footers that are displayed by Apache::Sandwich, then remember you control what the headers/footers are. For my setup, my header is not static. It's a mod_perl script that does cookie checking, prints the date and does a few other things. So if you want yours dynamic, just make the header an actual script and not a static HTML file. You can then (the most simple form) read in any files you want, ala SSI as well as do some other fun stuff. Jim -- Jim Serio - [EMAIL PROTECTED] Producer, World of Coasters

Test 2: Hello World
- Simple test to print "Hello World".
- For each of EmbPerl, PHP, AOLServer:

- As an example: here's the EmbPerl code:
[-

$a = $a . "a";
print OUT $a, "br";
}
-]
- Returned page was approximately 500 K.
Test 4: Small Database Query
- Fetch and display 1 record from a products database of about 300
records, searching for an exact match on an indexed field.
- Returned page was approximately 5K.
- Used persistent db connection in all cases.
Test 5: Big Database Query
- Fetch and display 24 records from a product database of about
300 records, using a "like" search on a text field.
- Returned page was approximately 118K.
- Used persistent db connection in all cases.
RESULTS:
- Results are "Requests per second". I'm not sure how to
interpret the numbers on an absolute scale, but the relative
comparisons should be somewhat meaningful.
- Each test was conducted 5 times and the average is shown.
- "ab" was used from the same machine as the web servers because
something "strange" happened when I ran it on another machine.

Re: ab weirdness...
Strange indeed. This is a 10M LAN.

Thanks!

I've included the SetHandler for the cgi scripts above because we had a similar problem with those, and by using sethandler we were able to get them probably executed. I am aware that this is a scoping problem with SetHandler of some sort. Is there anything I can do to run mod_include as the content handler and use the Apache::Block module (my custom one) as the access handler without the two interfering like this?

directoryindex is not retrieved
Hi! I have problem with index files for directories not being read under mod_perl. According to mod_perl guide this happened for those who "declared mod_perl configuration inside a Directory section for all files matching to *.pl.

My configuration is Directory /doc/root PerlAuthenHandlerApache::MyAuth::authen_handler . /Directory Everything works fine except for retrieving index files for directories. Requests for http://my.site.com/any/dir/ end up with message "you don't have permission to access /any/dir/ on this server" and line in error log "Directory index forbidden by rule: /proj/Web/94dec/any/dir/" I'm running Apache 1.3.9, mod_perl 1.21 staticaly linked on Linux box. And unfortunately I can't rewrite my configuration to use Files ... And there is DirectoryIndex directive in my configuration files. And my authentication/authorization handler doesn't care about the URL being requested, only the require field values. Anyone has looked into that really? Andrei --
Stacked Handlers and passing Objects

And yes, I have searched the archives and I have the apache modules book, but I did not find a clear answer to this question. My website that I am developing (web.carracing.com) uses 4 stacked handlers for each section of the site. The only one that changes is the 3rd handler for the content of the page. here is one of the configs: Location /Racing_Links SetHandler perl-script PerlHandler Apache_Car::Authen Apache_Car::Start_Page Apache_Car::Racing_Links Apache_Car::End_Page Options ExecCGI /Location The site is completely dynamic with not one page of html besides some templates I parse myself. The module Apache_Car::Authen is what I use to determine access and layout of every page requested. When a user logs in, Apache_Car::Authen then gets his/her personal data from a MySQL Database which is then used to layout the site to their personal prefs. Currently, I can use $r-notes and that works fine, but what I would like to do is use an module I have written and then just pass the object to the later stacked handlers so that the later handlers can grab necessary data from the objects methods. I gues the reason I want to do this is because when the member is authenticated, It would be easier and quicker to get the data from the DB and leave it in the object hash for the later modules. Again, please let me know if I am way off base with this thinking and a pointer to some examples of a better way would be much appreciated.

Then, let's say you get 1Mil in hits a day. 50% of those are IE5. Ok, that's 500K hits from IE5 asking for that 2K file. So that's 1Mb of data a day JUST for that damn icon. Over a month is 30 Mb of bandwidth JUST for that damn icon. Bandwidth is not cheap folks! Someone has to pay for bandwidth. And some plans only allow for 30 Mb a month. I was unable to glean a persuasive argument from your message, despite your liberal use of capital letters and explitives. You have several things wrong. The icon files are 16x16x8 bits, and the format requires 1KB. The icon is not requested on each request, only when a user bookmarks your site using IE 5. Clearly this number will be a tiny fraction of all requests a site serves. With caching effects, you can expect to transmit even fewer bites to the large ISPs. Last, nobody is forcing you to transmit the icon. You can simply redirect it using mod_rewrite or intercept it with a mod_perl log handler and discard the log entry. Remember folks, bandwidth costs money! Someone has to pay for it. Maybe not you but someone does. EVEN THE FREE HOSTS! This is not the point. If you have GIFs on your page, you are paying to transmit those, too. If you don't want to transmit the icon, don't provide the icon! There are technological means to handle this on the server side and it takes less time than complaining about it in public. I think the prevailing philosophy on this subject is dead wrong. On the web, any and all requests can and will come in. You cannot trust the client! If you rely on the web, you must be prepared to gracefully handle all situations that might arise. This might include a broken client making bad requests to your server in a tight loop (Mozilla M8), or it might include a client occasionally requesting a file that doesn't exist (IE 5).

embperl pages and braindead sucking robots

I use suffix .phtml for these pages, and the url looked like http://mysite//page.phtml/randomotherurl. The innocent embperl page delivered some contents with relative urls and the robot continued to fetch the same page with various URL suffixes, causing a loop and doing the equivalent of an Apache bench remotely.

I started programming perl about a year ago and have no other programming experience, so please forgive me if this is way out of scope. And yes, I have searched the archives and I have the apache modules book, but I did not find a clear answer to this question. My website that I am developing (web.carracing.com) uses 4 stacked handlers for each section of the site. The only one that changes is the 3rd handler for the content of the page. here is one of the configs: Location /Racing_Links SetHandler perl-script PerlHandler Apache_Car::Authen Apache_Car::Start_Page Apache_Car::Racing_Links Apache_Car::End_Page Options ExecCGI /Location The site is completely dynamic with not one page of html besides some templates I parse myself. The module Apache_Car::Authen is what I use to determine access and layout of every page requested. When a user logs in, Apache_Car::Authen then gets his/her personal data from a MySQL Database which is then used to layout the site to their personal prefs. Currently, I can use $r-notes and that works fine, but what I would like to do is use an module I have written and then just pass the object to the later stacked handlers so that the later handlers can grab necessary data from the objects methods. I gues the reason I want to do this is because when the member is authenticated, It would be easier and quicker to get the data from the DB and leave it in the object hash for the later modules. Again, please let me know if I am way off base with this thinking and a pointer to some examples of a better way would be much appreciated.

Upgrading to 1.21-2
I just upgraded to Perl 5.005_03 from 5.004_something. (I run Red Hat Apollo (5.2) on my box). I had to install GLIBC_2.1 and uninstall mod_perl-1.19-1. That done, Perl installed with only one hitch, the following error: /etc/localtime created as /etc/localtime.rpmnew Then I tried to install mod-perl-1.21-2.i386.rpm. It didn't take, but instead kicked back a "failed dependency error, Perl 5.005_03 needed" or something to that affect. perl -v from the command prompt returned 5.005_03 as the current version. Any suggestions as to why I can't load the mod_perl-1.21-2... rpm and why I have the correct version of Perl but it isn't being detected? Thanks, Glen
RE: Upgrading to 1.21-2
Did you install perl from source? If you did then RPM is unaware of perl 5.005x being on the box. As said several times before on the list..

Dear Mr. Baker,
If you have "never bothered" to find out why `make test' is failing
then obviously you don't have any "production mod_perl systems". In

the extent that now I don't trust any of it. The entire exercise is
written off to experience and I am looking for alternatives.

HTTP_NOT_MODIFIED
Hello, I'm asking this question again in a simpler form this time. Can Apache::exit() be used in an Apache::Registry script?

the mis-speakings of a good Perl contributor (JB) out of context and try

Embperl Subroutines
Hello Everyone,
I am in the process of developing an Embperl/Mysql site and have a
couple of questions.
One thing that I am doing now is making use of Embperl [$ sub $] [$
endsub $] for defining subroutines. If I read the documentation
correctly these subroutines will be 'imported' into any page that I
import them into. I see no mention of reuse of these subroutines, each
page seems to get it's own compiled copy in it's namespace.
I am wondering if during the Execute I can set the PACKAGE that the
subroutines are compiled into like:
Execute( { inputfile = '/include/subs.emb', package = 'Subs', import
= 1 } );
and then use
[- Subs::subroutine -]
in my pages.
I could run this once in my startup.pl, pre-compile the subroutines and
reuse them.
Thoughts,
Owen
Apache::Request
So I've been playing around with Apache::Request for the last day or two, trying to figure out what it's capabilities are for processing uploaded files. I was hoping to use it as the back-end of an HTTP-based API I'm creating. It looks like it requires that a "filename" parameter on the Content-Disposition MIME block header to exist in order to find the MIME block, or it will entirely skip the block. It can handle a missing "name" parameter just fine (which seems strange). Good Examples: Content-Disposition: form-data; name="test1"; filename="test1.txt" Content-Disposition: form-data; filename="test1.txt" Bad Example: Content-Disposition: form-data; name="test1" Has anyone else played around with Apache::Request in this way? -jse
Question on STDIN
In a perl apache module that I'm writing, I wanted to try to parse the
content of a POST myself. According to "Writing Apache Modules with Perl
and C", page 438, you should be able to read the content from STDIN using
Perl's read() and getc(), and using Perl's file operations.
When I use the STDIN statement, I get a single line that contains the
entire POST content, rather than just the first line of the post. Can
anyone think of why that would happen? Here's the snippet of my code:
$line = STDIN;
$r-print("$line\n");
In my response, I get the entire POST content echoed back to me, where I
only expected the first line. If I comment out the "print" statement, I
don't get anything echoed back (which is what I would expect). It really
looks like $line contains the entire content.
Any clues?

RE: HTMLEmbperl 1.2.0 HTTP header

$req_rec-status(REDIRECT);

[$ endif $]
Note: The display_errors_as_html method doesn't send out any headers of
it's own.
But I guess it prints to stdout. You should set optRedirectStdout (in your
server config), to let stdout go to the Embperl output stream. Otherwise
it's send directly and arrives at the browser, before Embperl sends it's
header. That's what you currently see

In my response, I get the entire POST content echoed back to me, where I
only expected the first line. If I comment out the "print" statement, I
don't get anything echoed back (which is what I would expect). It really
looks like $line contains the entire content.
If there are lines in it, perhaps $/ is undef'd (haven't checked)
therefore you could prolly harmlessly do something hokey like
my $line;

This site has thousands of hits per day (not sure of how many, though) and it should be faster (few images, no animations whatsoever). Can anybody tell me what could be done here? EmbPerl instead of PHP? mod_perl/apache tuning? Should database access be done through PHP or mod_perl? When should I use PHP? and mod_perl? do I need both? Well, which one are you using for talking to Sybase with? Choosing one or the other would reduce your memory requirements a bit. Performance-wise they really are quite similar. Choosing one over the other is more of a personal preference thing. -Rasmus

Re: Another IE5 complaint
Most of my users are .fr people. My logs show more than 70% of them as IE users. MS is clearly in the process of enjoying one more monopolistic situation. People just don't download Netscape. What's more surprising is the enormous proportion of IE5 users over IEx users. Seems to me that if we let them do every damn thing crosses their dumb minds, we are in for long-time troubles ;( Fabrice Scemama Eric Cholet wrote: Am I the only battling service vendor who actually feels good when somebody bookmarks my website ?

Maybe we're getting tired of MS initiatives, such as the very rude offline site grabbing IE5 does, the crude implementation of this favicon thing, the fact that IE5 replaces error messages with its own if they aren't at least 512 bytes or something, er, the list probably goes on a bit.

Re: EmbPerl, PHP continued...
RESULTS: - Results are "Requests per second". I'm not sure how to interpret the numbers on an absolute scale, but the relative comparisons should be somewhat meaningful. - Each test was conducted 5 times and the average is shown. - "ab" was used from the same machine as the web servers because something "strange" happened when I ran it on another machine. (I'll send a separate email regarding this.) 1000 requests, 1 concurrent ab -n 1000 -c 1 URL -- Test1 Test1(b) Test2 Test3Test4Test5 --- Apache w/ modperl/ 852.86 99.53217.2516.9678.1218.32 EmbPerl Apache w/ 836.47100.06560.7816.1598.7618.80 PHP AOLServer 100.01 99.72100.0612.89 156.3014.29 1000 requests, 10 concurrent ab -n 1000 -c 10 URL -- Test1 Test1(b) Test2 Test3Test4 Test5 Apache w/ modperl/ 890.37248.00262.4730.31158.5045.17 EmbPerl Apache w/ 957.30492.55559.7123.81268.3434.64 PHP AOLServer 758.54227.76816.65 5.97141.19 7.45 Well, I think it shows nicely that mod_perl-EmbPerl and PHP are in the same ballpark. This has always been my impression as well. PHP tends to be quicker on short simple scripts which your results also show while PHP 3 was not very efficient at handling large loops. This is reflected in your Test 3/5 numbers there where PHP is a little bit slower. But, certainly not by a factor of 10-20 as some people like to say. And this looping deficiency has been fixed in PHP 4. PHP 4 also brings an optional interpreted script cache along with an optimizer which can help out with really complex and time-consuming scripts. By the way, PHP 4 also works as a module in aolserver now (Zeus coming soon). Would be interesting to see if PHP could beat aolserver's built-in tcl engine. One thing that might be interesting to see would be the peak memory and cpu usage for each one. That would give some indication of scaleability issues. I have no idea how PHP will fare here. ;) Some improvements were made in PHP 4 in this respect though. -Rasmus
Re: ab weirdness...
When I use "ab" from another Linux box to fetch a static HTML page (about 6K in size) on a test server on the same network, "ab" reports: 3 requests per second versus about: 900 requests per second when "ab" is run directly on the test server. Strange. I don't see that here. I actually get better results when I run ab from another machine across a quiet 100M LAN. You must have something really funky going on. Massive collisions? Bad cable? Duplex problem? -Rasmus
RE: Passing params in Embperl...
I realize that that this is probably something incredibly easy that I've
just overlooked while reading the docs so I apologize ahead of time...
I need to pass a value that is dynamically generated at run time to the
next Embperl doc. I've tried doing the following:
$fdat{'application_id'} = 'some value'; and I've also tried using the
Apache::Session option of $udat{'application_id'} but when I read either
of these values in the next form it's blank.
Here's what happens... I have an initial page of an online
application. When submit is hit it returns to itself to perform error
checking, if there are no errors then the client is automatically
redirected to the next page of the application form.
Is setting $fdat{application_id} to a value enough to pass this along to
the next form or do I need to somehow provide this in the URL prior to
doing the redirect?
Setting $fdat{whatever} will have no effect on the next form, only for the
current page. You must insert a hidden field inside your form
input type=hidden name=application_id value="[+ $foo +]"
To use %udat to pass values, you have first to setup Embperl, so that it
uses Apache::Session. Read the docs about Session HAndling. If you are
successfull, you should see a message "Embperl sesssion handling enabled" in
your Apache error log, when Embperl starts

RE: Embperl Subroutines
One thing that I am doing now is making use of Embperl [$ sub $] [$
endsub $] for defining subroutines. If I read the documentation
correctly these subroutines will be 'imported' into any page that I
import them into. I see no mention of reuse of these subroutines, each
page seems to get it's own compiled copy in it's namespace.
No, the subroutines are compiled in one package, and only the names are
imported in each page from which you call Execute with the import parameter.
So the subroutines get resued. It's just the same as Perl's "use".
I am wondering if during the Execute I can set the PACKAGE that the
subroutines are compiled into like:
Execute( { inputfile = '/include/subs.emb', package = 'Subs', import
= 1 } );
and then use
[- Subs::subroutine -]
in my pages.
I could run this once in my startup.pl, pre-compile the subroutines and
reuse them.
You can do so. Use import = 0, to only compile your subroutines and not
import the names in the namespace of your startup.pl:
Execute( { inputfile = '/include/subs.emb', package = 'Subs', import =
0 } );

Re: Question on STDIN
When I use the STDIN statement, I get a single line that contains
the entire POST content, rather than just the first line of the post.
Can anyone think of why that would happen? Here's the snippet of my
code:
$line = STDIN;
$r-print("$line\n");
1. There might not be more than one line.
2. Maybe $/ is set to undef() or an incorrect value. If you are on a
DOS/Win machine, it might be searching for "\r\n" whereas "\n" might be
used.
In both case, the snippet spidaman posted should do the trick:
my $line;
{
local $/="\n";
$line = STDIN;
}
$r-print("$line\n");

Sorry for such a simple question on the mailing list but I don't know where all the resources are for this YET! Thanks! From http://www.nodeworks.com/asp/faq.html (also FAQ section of 'perldoc Apache::ASP') Apache errors on the PerlHandler directive ? You do not have mod_perl correctly installed for Apache. The PerlHandler directive in Apache *.conf files is an extension enabled by mod_perl and will not work if mod_perl is not correctly installed. Common user errors are not doing a 'make install' for mod_perl, which installs the perl side of mod_perl, and not starting the right httpd after building it. The latter often occurs when you have an old apache server without mod_perl, and you have built a new one without copying over to its proper location. If you haven't installed mod_perl, check out http://perl.apache.org You will also want to put a space between Global /tmp :) -- Joshua _ Joshua Chamas Chamas Enterprises Inc.
