To elaborate a little on this thread: I find ethereal http://www.ethereal.com/ useful for debugging situations like this. Certain browsers (that I won't name) behave in quirky ways that GET or lynx won't emulate, so it's often worth running ethereal in the background whilst using your site with various browsers, then analysing TCP streams in ethereal to see exactly what's happening.

Re: caching questions

Well, you can't, unless you use threads. I know there's IPC, and also memcached. I've used IPC::Shareable before, but don't know if that's the route I'd wanna go. It's not. IPC::Shareable is very slow. If you want to share data, use Cache::FileCache, Cache::Mmap, MLDBM::Sync, or IPC::MM. Has anyone implemented a good caching system that sets up a global cache that you don't have to check constantly because you happen to have been served out by a child that doesn't have the latest cache from DB? One single memory object? The systems I listed above all use a shared cache that will have the same data regardless of which process accesses it. - Perrin
Use mod_perl2 in production environment?
Hi guys, within the next 2 months I have to create an webapplication from scratch using mod_perl for a customer. The customer wanted to host the application at his provider which refuses the installation of Apache2+mod_perl2 because he considers them to be Beta-Software whereas he considers Apache1+mod_perl1 under Win32 to be stable. My job is it now to write a response to our customer and I want to have some information from developers and/or users about the stability of Apache2+mod_perl2+Unix and Apache1+mod_perl1+Win32. thx Tom

RE: mod_perl not sending cookies
Andrew, Ya need to remember to CC the group as well. Copied from an oldish Netscape spec: -- domain=DOMAIN_NAME When searching the cookie list for valid cookies, a comparison of the domain attributes of the cookie is made with the Internet domain name of the host from which the URL will be fetched. If there is a tail match, then the cookie will go through path matching to see if it should be sent. Tail matching means that domain attribute is matched against the tail of the fully qualified domain name of the host. A domain attribute of acme.com would match host names anvil.acme.com as well as shipping.crate.acme.com. Only hosts within the specified domain can set a cookie for a domain and domains must have at least two (2) or three (3) periods in them to prevent domains of the form: .com, .edu, and va.us. Any domain that fails within one of the seven special top level domains listed below only require two periods. Any other domain requires at least three. The seven special top level domains are: COM, EDU, NET, ORG, GOV, MIL, and INT. The default value of domain is the host name of the server which generated the cookie response. path=PATH The path attribute is used to specify the subset of URLs in a domain for which the cookie is valid. If a cookie has already passed domain matching, then the pathname component of the URL is compared with the path attribute, and if there is a match, the cookie is considered valid and is sent along with the URL request. The path /foo would match /foobar and /foo/bar.html. The path / is the most general path. If the path is not specified, it as assumed to be the same path as the document being described by the header which contains the cookie. -Original Message- From: Andrew Fritz [mailto:[EMAIL PROTECTED] Sent: Thursday, March 13, 2003 7:07 PM To: Tom Murphy Subject: Re: mod_perl not sending cookies Bingo!

PerlCleanupHandler called from default-handler
I have written a Apache::DBILogger style log mechanism. It is enabled via the perl.conf in the Server context as: PerlCleanupHandler NC::LogHandler It works correctly, except for the fact that request handle by the default-handler do not call this handler. The mod_perl cookbook makes note that: ..a C module has to specifically want this processing to occur-it is not called automatically. How do I allow for this handler to be called on all requests? Note I also tried this as a PerlLogHandler to no avail. TIA, Tom Murphy
RE: crazy problem
Here's the gist ... when I run some code which looks like ... my result = `/usr/local/bin/matlab input_file.m`; ... from a perl CGI, then matlab (a commercial math package) segfaults. However, when I run it from mod_perl on the same server it runs fine (it runs fine from the command line, btw). Sounds like a dynamic lib problem. W/o knowing your OS its hard to say what variable Apache is setting but try looking at one of these SHLIB_PATH,LD_LIBRARY_PATH. For anyone who may have Matlab available, btw, this is only with Matlab 6. Matlab 5 (which we no longer have a license for) works just fine. Yup, I suspect Matlab 6 requires a newer shared library of some sort. Cheers, Tom Murphy
Access to ap_send_fd_length in 1.0
I have a client for whom I manage documents, some of which are in pdf format. The documents are not in the web tree, and are served based on custom access etc., and some are encrypted on the files system. I am successfully do all this, and ultimately use send_fd to send the file(s). The client has noticed that through the managed process, the time to view the pdf is longer than viewing the same file through the default handler. I have discovered that this is most likely due to the fact that Apache is byteserving the file, allowing the first page to be viewed even though the complete file has not been downloaded. The complete time to download between the default handler and my handler are quite close, but the document comes up for partial view much quicker with the default handler. I have been able to use Apache::File to modify my handler to recognize when a byteserving request has come in ( using ap_set_byterange), and access the ap_each_byterange call to decode the header. However, it does not seem like the ap_send_fd_length is mod_perl accessible. Is there any issue with adding access to this API function? Also, will I have a problem setting the PARTIAL_CONTENT response? With the clients encrypted documents, I have the documents in memory only. I would like to use the send_fb/send_fb_length call in a similar fashion. I haven't done any XS/guts type programming, so I'm hoping this will be a relatively simple task. Thanks for any pointers, Tom Murphy

PerlHandler Inheritance
This is probably a pointless question, but I'm mostly just curious if there is any way to get this to work. I've got two modules, Parent.pm and Child.pm. Parent.pm has a sub handler in it, and Child.pm has Parent in ISA. I can run a little driver script over these two and call Child::handler and have it execute Parent::handler, so I know the inheritance is working. However, if I setup my location directive like this: Location /test_child SetHandler perl-script PerlHandler Child /Location It tells me Undefined subroutine Child::handler called. I'm using Parent Child in startup.pl, and also doing a use Parent; in Child.pm for good measure. Is there any way to get mod_perl to execute the handler in the parent class automatically? Am I just completely missing something?

so long as you're preloading Child.pm via startup.pl or PerlModule,
you probably just need to prototype your handler:
sub handler ($$) {
my ($class, $r) = _;
}
or, with later perls
sub handler : method {
my ($class, $r) = _;
}
you're using a feature called method handlers so you can look that
up in the mod_perl literature for more information.

$test_pass = crypt $sent_pw,$real_pass;
This is what I tried first (it's common in examples). Results were terrible.

[mp2.0] wrong crypt behavior
Hello,
I use own PerlAuthenHandler module to verify users' login and password from
database.
For comparsion of password user entered and password stored in database is
crypt function used.
Here is the code:
my $real_pass = $d-[0][0]; # crypted password from database
my $salt = substr $real_pass,0,2; # salt
my $test_pass = crypt $sent_pw,$salt; # in $sent_pw is the password user entered
if ($real_pass eq $test_pass) {
$r-subprocess_env(REMOTE_USER = $user);
return OK;
} else {
$r-note_basic_auth_failure;
return AUTH_REQUIRED;
}
Problem: Sometimes, although user entered correct password, is authentication
rejected. I tried logging values of $real_pass and $test_pass and they
differed. When I add line
$r-log_reason(User $user tested (.$real_pass./.$test_pass.)...,);
just before 'if' statement behavior is most of time correct.
Can anybody help me? Thanks.

Possible naming error when extracting mod_perl 2 tarball

SOLVED: How to access base environment from Perl sections
Perhaps it's obvious but after years of mod_perl, I was blocked,
probably because using this basic Perl ability is frowned upon in
mod_perl due to performance issues. Of course, during startup,
performance isn't an issue. :-)
In my case, I wanted to PerlPassEnv all environment variables that began
with EWINGZ_
Perl
for ( grep { /^EWINGZ_/ } `env` ) {
my ($key) = /^([^=]+)/;
push PerlPassEnv,$key;
}
/Perl
Stas: I asked this question almost exactly a year ago and nobody
answered it. I asked it yesterday, and again nobody answered it. Perhaps
this should be the Perl Sections section of the guide? After all, the
guide already mentions something very similar to this.

Funny, but there are too many things in the guide to remember. The new
search feature exposes them all, just remember to use it.
I was just about to add your tip, when I've found it
http://perl.apache.org/docs/1.0/guide/porting.html#Passing_ENV_variables_to_CGI
which was added about 3 years ago:
http://perl.apache.org/docs/1.0/guide/Changes.html#05_17_1999_ver_1_11
may be we need to add a xref from the Perl sections section?
Yes, that makes sense.
I would NEVER have looked there, as:
1) It wasn't in the Perl or Configuration section
2) I wasn't trying to pass environment variables to CGI scripts. :-)
I'll have to learn to use the search functionality!
I'm not sure if I've said it before, but thanks for doing all that you
do for the mod_perl community. I appreciate it.

mod_perl install on SGI
Greetings, I am trying to install mod_perl with apache_1.2.26 on and SGI running 6.5.16. apache was installed from the freeware.sgi.com website using their very nice installer. Unfortunately, the clean up after installation seems to remove the Makefile that is used by mod_perl's Makefile. So running install mod_perl from cpan, I get the question Please tell me wher I can find your apache src [ ../apache_x.x/src] I can't seem to give it a path that works. I know the executable is at /usr/freeware/apache, but that gives the message can't open /Makefile No such file. I've also tried using /var/inst/fw_apache which is the downloaded source file. No dice. Any suggestion would be appreciated. Thanks, Tom Keller Thomas J. Keller, Ph.D. Oregon Health Science University MMI Research Core Facility 3181 SW Sam Jackson Park Rd.

Knowing your limitation - was Re: [JOB] Crack OOP Perl whitebox tester wanted
Thanks for your response, Zac. Our tech team is very small. I'm the manager of the group, and my management style would best be described as lackadaisical. :-) So, you're right, this requirement is based upon management weakness. I knew that when I posted the job offer. In fact, I even told that to the employee who was leaving for Washington D.C. as the reason why I couldn't keep him on. He understood completely, having worked with me. :-) While I agree that it would be ideal to simply pick the best person for the job, this obviously isn't completely realistic. For instance, we have a certain pay range that we can afford, and that will artificially limit who we can consider. Other people won't even know we have an opening. Others still might have a language or communications barrier that makes it impossible for us to work with them. Notice that this is not actually his deficiency, but ours. If we could just speak (insert language here). I just don't see adding one additional limitation to that by wanting someone to come to the office as all that big a deal. Many people prefer it, and in this economy, help is not scarce and people are willing to go the extra mile. After all, it's not about getting the best person, it's about getting the best work done. If I know that I can't effectively remote manage somebody so it would be silly for me to attempt this in vain.

This doesn't cover why small writes are atomic though. And man(2) write doesn't seem to either, but the open man page on my system says O_APPEND The file is opened in append mode. Initially, and before each write, the file pointer is positioned at the end of the file, as if with lseek. O_APPEND may lead to corrupted files on NFS file systems if more than one process appends data to a file at once. This is because NFS does not supAD port appending to a file, so the client kernel has to simulate it, which can't be done without a race condition. which certainly implies that you can expect local files _not_ to get corrupted. p.s.

Re: Load Balancing, mod_proxy, rewrite problem
I think I had a similar problem. It's a while since I tackled it, so I might
be wrong. In any case, I was having problems doing proxy with a rewritemap.
My reason for wanting to do this was so I could use the weighting feature of
rewritemaps to do weighted load balancing between frontend and backend
apaches.
I mailed Engelschall, but I hear he gets so much mail about mod_rewrite that
it takes him years to respond.
In any case, I have a patch to mod_rewrite that fixed the problem for me.
The breakdown of the issue was that mod_rewrite wouldn't do a proxy on a
subrequest.
Be warned: I think this patch causes problems with the automatic adding of
trailing /'s on URLs.

On closer examination, I don't think this will solve your problem - this
helps when you want to proxy something that's been included via mod_include.

Re: Solaris 8 lockups
Thank you, and Marc as well, it looks like it was a combination of both
version options and having it compiled as a DSO. We've upgraded
mod_perl and apache and no longer have mod_perl as a DSO, and except for
new error messages popping up (nothing serious, mostly just slightly
sloppy coding issues that will be easily fixed), it looks like it's
finally stable, at least for the last little while.
Thanks again for the help.

Re: Sharing Variable Across Apache Children
Is the webserver useful if you have an error that warrants sending a mail? If sending an email means the server is broken having a flood of mails may be a feature. It will be incentive to fix whatever is breaking your server/db. Also, I would strongly recommend keeping your warning system as simple as possible. Why not have the servers output an error message to a file on a single nfs file system and then setup a crontab to watch the file(s)? One machine could run the crontab every minute. 60 mails/min isn't too much unless you are forwarding it to a beeper in which case you could write a quick script to only mail once per unit time.

The truth is, I don't want a separate system (as per the e-mail about having an error handling server), and I don't want to have to manage the e-mail on the receiving end because I'm not the only person who receives it (didn't mention it, but I guess that's important). Further, I have no control over the mail server that handles the incoming mail so I'd have to handle it on the mail client (Outlook / Netscape Mail) resulting in the same problem I have now.

That sounds kind of slow, since it requires a network connection to be created every time and some synchronous processing on the other end. It also depends on that box always staying up. I think e-mail is actually a good approach, since it's a robust message queuing system and if you use something like qmail-inject to send the e-mail it takes almost no time at all for mod_perl to finish with it and move on. You just need to process those messages on the other end instead of looking at the raw output, i.e. use Mail::Audit to keep track of the current state and remove duplicate messages. Matt posted something about PPerl yesterday, which could make a Mail::Audit script more efficient by keeping it persistent. - Perrin -- 28 70 20 71 2C 65 29 61 9C B1 36 3D D4 69 CE 62 4A 22 8B 0E DC 3E mailto:[EMAIL PROTECTED] http://thecap.org/

Extracting the data with a single query and recursing it in RAM is a much more db and cpu friendly idea.

What's interesting is that if I turn swap off and back on again, what? doesn't seem to me like you are agreeing, and the original quote doesn't make sense either (because a shared page is a shared page, it can only be in one spot until/unless it gets copied). a shared page is swapped to disk. It then gets swapped back in, but for some reason the kernel seems to treat swapping a page back in as copying the page which doesn't seem logical ... anyone here got a more direct line with someone like Alan Cox? That is, _unless_ you copy all the swap space back in (e.g. swapoff)..., but that is probably a very different operation than demand paging. the sharing is restored! So, now I'm tempted to run a crontab every 30 minutes that turns the swap off and on again, just to keep the httpds shared. No Apache restart required! Seems like a crazy thing to do, though. You'll also want to look into tuning your paging algorithm. Yeah... I'll look into it. If I had a way to tell the kernel to never swap out any httpd process, that would be a great solution. The kernel is making a bad choice here. By swapping, it triggers more memory usage because sharing removed on the httpd process group (thus multiplied)... the kernel doesn't want to swap out data in any case... if it does, it means memory pressure is reasonably high. AFAIK the kernel would far rather drop executable code pages which it can just go re-read ... I've got MaxClients down to 8 now and it's still happening. I think my best course of action may be a crontab swap flusher. or reduce MaxRequestsPerChild ?

Re: loss of shared memory in parent httpd
No, I can't explain the nitty gritty either. :-) Someone should write up a summary of this thread and ask in a technical linux place, or maybe ask Dean Gaudet. I believe this is a linux/perl issue... stand alone daemons exhibit the same behaviour... e.g. if you've got a parent PERL daemon that fork()s ... swapping in data from a child does _not_ have any affect on other copies of that memory. I'm sure swapping in the memory of the parent before fork()ing would be fine Admittedly, my experience is from old linux kernels (2.0), but I would not be suprised if current ones are similar. I'm sure it is the same on some other platforms, but I haven't used much else for a long time. -- [EMAIL PROTECTED] | Put all your eggs in one basket and http://BareMetal.com/ | WATCH THAT BASKET! web hosting since '95 | - Mark Twain

We're using MASON, don't know if that is information needed in this, but

I believe the usual way to access POST data, $r-content, is only
for form data. To get XML data, try this:
my $buf = '';
$r-read($buf, $ENV{CONTENT_LENGTH});
This is a general mod_perl API issue, and not necessarily specific
to Mason, though Mason may have some other API specific to this.
This may in fact collide with Mason form processing if there is
any, since a mod_perl application will hang if it tries to
read the POST data twice.
Mason generally does an automatic read of POST data, specify what form
fields you want, and it'll stuff the values into variables named the same
as the name fields in the POST data. You should just be able to have the
XML be the value for some name/value pair, then do all your XML
parsing/DBI work on that value.
Re: Cookie authentication
The aim of the cookie example in the eagle book is a bit more than just authentication. Most of the answers here to use a session ID here are quite right for most purposes, but the code in the eagle book offers to store information on the client side with the security of a signature. Its NOT just authentication. This has some advantages for applications which are on more than one server, which have to use an expensive central DB lookup and/or are not connected at all, since the only thing to share is the secret. This is quite perfect of a decentral intranet. In my last project i did a LARGE single sign on implementation over loads of applications which used those cookies for authentication and for getting the DN and preferred language out of the cookie, all w/o any need of further DB lookups or LDAP requests. Since the logic is quite simple its also possible to parse/check the cookie in tomcat or any other web application and leave the logon to a central server. The secret is then shared over an https connection. By rotating the secret one gets a certain level of security (and automated logout). More or less the eagle book offers the full implementation of a single sign on solution with some nice features already implemented, missing is the secret rotation with more than one secret and some intelligent caching of it (just retrieve anew on a failed signature check e.g. which is in some other cookie module on CPAN?). What its not in my opinion is a simple authentication, its to complicated for that. A simple session ID suffices - and with session IDs there are all those nice things to play as putting them into the DNS, doing some url rewriting with mod_rewrite or just putting them in every URL automagically with some class. I did not know that you could verify that someone has cookies turned on. Can you point me to where i can find out how to do this? Is there a variable that you can check? The ticketlogin example in the eagle book does this by setting a redirect_url cookie before redirecting you to the login page, if this cookie is missing there the - sorry youve no cookies please enable them - page is shown.

mod_perl, pipes, and No child processes
Hello all. I'm writing an app that opens a pipe to sendmail, which if
memory serves, forks off a child process of apache to do the pipe, then
exits as soon as it's finished.
I was doing this with MIME::Lite, and it's been working absolutely
splendidly on Linux and on Solaris 7. However, on Solaris 8 (and I don't
know if this is related to the OS or not) it gives me all sorts of
problems. Namely, this started after checking the return code on a
MIME::Lite object called $msg after calling the send method. It usually
returns a 1 on success, but on the new box it was returning 0, despite the
fact that the e-mails were actually going out.
I ended up writing a test on that just opens a filehandle to |
/usr/lib/sendmail -t -ei -eom, then printing to the filehandle, and
closing the filehandle. If memory serves, it's almost impossible to get
something accurate out of this statement in mod_perl:
open(SENDMAIL, | /usr/lib/sendmail -t -ei -eom) or do_something();
As that just reports on whether or not an apache child process was able to
spawn, not whether it was actually able to open the pipe to sendmail.
So, that runs fine, then the print works as I actually get the e-mails
it's trying to send, but this bit of code:
close(SENDMAIL) or print STDERR Filehandle close failed: $!;
spits out: Filehandle close failed: No child processes
Any ideas what is causing this? Like I said, the mail goes out fine, but
it makes it pretty difficult to check the return code since it's always

Any ideas what is causing this? Like I said, the mail goes out fine, but it makes it pretty difficult to check the return code since it's always coming back false. Shouldn't you check $? instead?

Well, on the shell and every other program, an exit status of 0 means success, and a higher one means an error of some kind. Btw: /bin/false ; echo $? == 1 /bin/true ; echo $? == 0 Also, the SIGCHLD is sent when a child exits, no matter if in error. You should then check the $? for the reason of the exit and for the return code, if exited normally. Regards, Luciano Rocha I've done this now and am getting back a -1 in $?, despite the mail itself succeeding. How can I check the reason for an error code on $? ?

The proxy machines were pretty basic, the search servers were heavy on CPU power, and the mod_perl servers were heavy on RAM. There were a lot of machines in the cluster, but I don't remember exactly how many and it changed over time. There were dozens of mod_perl servers when the cluster was at its biggest. Most of them were idle for the majority of the time, but they were all needed for the occasional peak load.

Galleries/ModPerl/Images
I just caught the end of the discussion about Stonhenge::Pictures and Apache::Gallery ... I have been working on setting up a photography site for myself and a few other digital photographers. Is there a reason NOT to put the images in a database? It certainly seemed to speed up pattern searches on my site. The site is up in php right now (had to brush up for a job), but will be redev'd in mod_perl once I find out what the state of gallery management is for mod_perl. I've used a MySQL backend to hold the images in BLOBs (I have a table for each of the common sizes). Uploads go to a images table (original size) and then the database resizes so it doesn't have to do it on the fly. Maybe those of us doing gallery type stuff could get together and work on something in a more organized fashion?

Re: POST params with Location
There could be something I'm missing here, but I believe you need to use

content() you can't call it again, so hang onto whatever comes out of it.
Also...isn't it $r-args() or am I just completely missing something here?
You can always do the whole $r-method() eq 'GET' ? $r-args() :
$r-content(); dealy-bob too...

When I call the app with GET params, everything works fine. When I use

Apache::Request it looks like I should automatically get the params, ala
CGI.pm. Oh yeah, and CGI.pm doesn't work either, so it doesn't seem to
be an Apache::Request problem.
Am I doing something wrong? Does Location not support POST params? All

Re: $r-args()
Once you change the method to GET and put the content in with $r-args();,
it becomes GET data from the query_string. All the POST data is lost
when you call content(), so you can no longer read it as POST data with
$r-content() again.

So your goal is to turn a post request into a get request using an
internal redirect.
However, in my called handler, no Post data can be read. Can any one
tell me why is that?
Any comments welcomed...
param does not work like args, and $content in this example will
return the number of param keys (IIRC).
I think you want
my $content = join('',map{$_.=.$r-param($_)}($r-param));
Which should solve your problems (I think).
I am affraid it did not work. I have no problem reading the data in the
current handler, but right after redirect, which is also required to
read the data, I loose all the POSTED data.

Environment variables and mod_perl
I'm working on a project that is highly configurable via environment
variables.
I'd like a way to get those environment variables into my mod_perl
processes so that the mod_perl portion of this project can be configured
the same way as the non mod_perl portions.
I know that I can use PerlSetEnv and PerlPassEnv. I've used these with
my current configuration and they work. The problem is this: I'd like a
method to do this flexibly so that when one of my team created a new
configuration environment variable, they don't need to change two files,
the environment setup shell script and the httpd.conf file!
All the environment variables begin with the name of our company in
upper case letters, followed by an underscore character. This code
prints them all out just perfectly outside of mod_perl:
[tmornini@millenium conf]$ perl
for my $env ( grep /^EWINGZ_/,keys %ENV ) {
print $env\n;
}
EWINGZ_DBI_USERNAME
EWINGZ_ERROR_DB
EWINGZ_CODE_BASE
EWINGZ_ASSERT_ASSERTIONS
EWINGZ_LOG_FILE
EWINGZ_LOG_BASE
EWINGZ_LOG_SPREAD_GROUP
EWINGZ_HOST_NAME
EWINGZ_OBJECT_WO
EWINGZ_LOG_UPPER_LEVEL
EWINGZ_SPREAD_NAME
EWINGZ_LOG_OBJECT
EWINGZ_DBI_PASSWORD
EWINGZ_LOG_LOWER_LEVEL
EWINGZ_DBI_DATASOURCE
EWINGZ_OBJECT_PR
EWINGZ_OBJECT_RO
EWINGZ_OBJECT_RW
However, this code doesn't work so well in a Perl section in
httpd.conf:
Perl
open FH,'/tmp/env.txt';
for my $env ( grep /^EWINGZ_/,keys %ENV ) {
push @PerlPassEnv,$env;
print FH $env\n;
}
print FH All done\n;
close FH;
/Perl
After startup, 1) The environment variables are NOT passed and 2)
/tmp/env.txt contains a single line:
All done
which means that at startup, these environment variables aren't
available to Perl sections, either. This does jive with page 423 of the
Eagle book.
Stas' excellent Guide is somewhat confusing on this subject:
http://perl.apache.org/guide/config.html
To pass all environment variables to the children with a single
configuration directive, rather than listing each one via PassEnv or
PerlPassEnv, a Perl section could read in a file and:
But this won't work for the same reason as above, namely, the
environment variables are visible at that time, and I don't want to
write a Perl script to parse a sh script! :-)
Also, I think that pushing an arrayref into @PerlPassEnv doesn't seem to
make sense since PerlPassEnv only takes a single argument. Looks like
this is an error that the line should read:
push @PerlSetEnv, [ $key = $val ];
Or have I been smoking again? :-)
How can I get around this? Thanks for everyone's time and attention!

Good lord are you right. You'd think that after all the revisions they've had of this software so far, somebody might have found a tab key or something. Also, note that it technically doesn't always work. The big thing you should watch out for is if one forum gets too many threads (usually when one of ours would reach around the 3000 mark), the software will just die. It'll completely lock up and use almost all the CPU until you go in and kill the apache processes. This was on a pretty fast machine in the meantime... 2. any problems with it under mod_perl? I have it running fine under PerlRun but I am not so sure it'll behave under Registry. I believe we ran it under PerlRun as well, but Registry I remember having some issues with. I'm sure that it can be tweaked to run under Registry, but as you said, the code is so horrific that after a couple of hours of pouring over that madness, I decided that I preferred jamming nails into my forehead as opposed to trying to get it to work right.

If you're a good Perl programmer who has a strong sense of the way it should be and can be simultaneously mean, nasty, angry, distrustful and unforgiving to Perl code and the opposite to people then we'd like to talk to you. Ideally you'd live in San Francisco, or thereabouts. I don't, however, so telecommuting is definitely an option. Pay and benefits are good, though it's no longer 1998. :-) Best benefit is working with a small group of people that are highly motivated by doing it right. -- -- Tom Mornini -- eWingz Systems, Inc. -- ICQ 113526784
RE: Apache 1.3.20, modperl 1.25, win32
Okay, I'm confused now. I thought those binaries were just for people who didn't have a win32 compiler handy. Don't they just use the regular source tree? I build mod_perl off of the apache source using nmake and visual c++. Here's a test: make a frameset with three panes. In the first two, call a mod_perl script that prints the time, pauses for 5 seconds, then prints the time again. The third one should just be a static image. When you try to load the page, you'll know if isn't running multithreaded if the panes in the frameset load sequentially; as in the second pane loads only after the first is finished. This request takes 10 seconds on my build, instead of the 5 it should take if both scripts ran concurrently. The problem I have is that my site uses a mod_perl content handler on nearly every html page for dynamic content. Obviously, running requests one a time would not work. I really hope there is a solution for this, because otherwise I have to figure out how to duplicate this in IIS (which means make an ISAPI extension and embedding perl in it... multithreaded perl at that). I'd like to stick with Apache, because I can move to Apache 2 eventually, if I change to IIS, I probably can never go back.

Re: templating benchmarks...
This benchmark can be very non-representive. If you don't know how to optimize each and every thing under test, you end up with unfair benchmark and come to potentially wrong conclusions. Take TT, add compiled template caching on the disk and shared TT object and I bet TT won't be at the bottom. In any case always remember that it's extremely hard to run a fair benchmark. I'd say it's almost impossible. The only fair benchmarking can be done if you know all the in's and out's of the 'things' under test and provide many benchmark tests each exploring a single property and not just 'one for all' benchmark. Of course it's a good thing to have benchmarks, but they all should be taken with a grain of salt. Absolutely. But I'd like to bring up something I've noticed in benchmarking 'real' sites: many, if not all, of the templating solutions appear to parse the whole of an html page. This is at least true of Apache::ASP and HTML::Mason, which I have used. Is it not ? I have produced really dramatic differences in performance in a two-tier setup by judicious use of mod_include vs. wholesale proxying of pages with dynamic content through to the mod_perl/Apache::ASP server. For example: In a situation with 1 lightweight frontend proxy and two backend mod_perl/Apache::ASP app servers ( with load distributed evenly using a patched mod_rewrite and its ability to select randomly from a list in a file ) , in one part of the site the dynamic headers and footers are generated by using !--#include virtual=/apps/include/pane.html?pane=headerlocation=$REQUEST_URI --, where the file being included is in fact proxied back to the app servers to receive content; in other parts of the site similarly simple pages are proxied in their entirety to the app servers. The results I can produce ( granted only with 'ab' ) are stunningly different: when I request the header and footer from the app servers using mod_include plus my modified mod_rewrite ( the stock version refuses to rewrite proxied requests ), I get up to 600 requests / second. When proxying the whole page through I get around 6 requests / second. Granted, I have other major bottlenecks involved: using Berkeley DB v1.x for session state, for one. Perhaps this explains some of it -- maybe the proxied header/footer requests never make session calls. I suspect that the wholesale parsing/eval-ing of html pages also plays a part. What do y'all think ?

I hope this isn't some sort of soft reference.
Some of my code I have arrays of strings or ints.
I might add 100 or more items to each array. The strings could be
50 characters long.
What happens to the array at the end?
Should I have a
undef @upper_id ;

If I don't have this does it mean the array just stays in memory until
the child is stopped?
A the moment the max child life is set at 300.
This is VERY low.
Any help or pointers would be greatly appreciated.
Fairly tricky question: Answers are my own, gleaned from years of faithful
mailing list reading.
1) It's lexical, so it goes out of scope and is destroyed when that
happens.
2) However, as an optimization, perl pretty much never releases
back to the OS memory once used for variable storage, which saves
on calls to malloc() and free().
3) All memory is freed when the child dies.
So, you don't need to do anything, but you'll never get the memory back
until the child dies.
It will run fast, however. :-)

Scott's is correct - he said the push() happens inside a different
subroutine, and the array is passed to it by reference.
Yes, that's obvious, now that you've pointed it out and I've read

forced win32 mod_perl
My company, to my objections, recently decided to force all of our new servers to running only Win2k. I won't go into the details, but let's just say that in our standard hosting facilities, nothing runing Linux is allowed anymore. This kinds of screws my department, as we have just finished development on a Linux/Apache solution tied heavily into mod_perl for a support web site. This leaves me with few options: 1) Run Apache/win32 and mod_perl. 2) Run IIS 5 and use an ISAPI handler to hook into my perl code. Could anyone help me out here? The first option is bad because of mod_perl's reduced functionality on win32 in version 1.25 (no threads, to my understanding). Option 2 is evil because I'd have to figure out some way to get an ISAPI extension to call perl code in a multithreaded way, and I'd have to use IIS. Am I stuck waiting for Apache 2 and mod_perl 2 to get to a point where they'll work in a production environment, or am I simply screwed and have to work around my company's dumb decree? Any help would be appreciated, although no comments on my company's IT policies, please... :) -Tom _ Get your FREE download of MSN Explorer at http://explorer.msn.com
Re: forced win32 mod_perl
It was my impression that PerlEx handled the persistance and what not, but it wouldn't allow one to make a content handler using perl. I need some way of processing every html file through my TemplateHandler::handler method. The way I was doing this was telling Apache to use my method as the content handler, instead of Apache just return the results, I was processing the file and sending those results to the client. PerlEx only does the part that keeps the perl interpreter running, right? If it does more, is there documentation that shows how this is done? I certainly couldn't find anything about content handlers on their sites.

Re: Throwing die in Apache::Registry
Mark--
While you may be having problems with segfaults because
of expat = yes rule-- i was having similar problems
with XML parser relating to the the die statement.
I do the same thing as far as eval'ing the parsefile
call. Also, I removed the die statement from parser.pm
(v 2.29 line 240 or so) so it would return a useful error
message rather than just die uninformatively.
Maybe this is what you were asking about?

It should still work. An eval{} is scoped like any other block. Maybe you

More likely is a b0rked $SIG{__DIE__} handler, like fatalsToBrowser. Yick.

LoadModule perl_module libexec/httpd/libperl.so
AddModule mod_perl.c

perl
