Problem comping mod_perl and mod_dav statically at same time...
Hi All, I am trying to compile the following things together: * apache_1.3.23 * mod_dav-1.0.3-1.3.6 * mod_perl-1.26 If i compile apache with mod_dav OR mod_perl it works fine. However, if i compile them both in then httpd always segfaults as soon as i pass it any request. The way i configure before compiling is: ./configure --enable-module=all --activate-module=src/modules/perl/libperl.a --activate-module=src/modules/dav/libdav.a - My actual issue is that i want mod_perl working and mod_dav working properly - i don't really care about how they are linked (static is preferable but not necessary). If i compile only mod_perl in statically and then compile mod_dav as a DSO (.so) file. Then the server stats up, but unfortunately a: OPTION /dav/ HTTP/1.1 Host: my.host.com:80 Gives me the following response HTTP/1.1 200 OK Date: Thu, 14 Mar 2002 08:01:49 GMT Server: Apache/1.3.23 (Unix) DAV/1.0.3 mod_perl/1.26 Content-Length: 0 MS-Author-Via: DAV Allow: OPTIONS, MKCOL, PUT, LOCK DAV: 1,2,http://apache.org/dav/propset/fs/1 Content-Type: text/plain BUT the response i really want is one that includes the header: Allow: OPTIONS, GET, HEAD, POST, DELETE, TRACE, PROPFIND, PROPPATCH, COPY, MOVE, LOCK, UNLOCK Otherwise of course WebDav will not work properly... - The relevant section in my httpd.conf file is: # # Web Dav Stuff... # DAVLockDB /tmp/DAVLock DAVMinTimeout 600 Location /dav AuthName DAV Realm AuthType Basic AuthUserFile /home/simran/netchant/www/pa/conf/.htpasswd DAV On Options Indexes AllowOverride All #Limit GET POST PUT DELETE CONNECT OPTIONS PATCH PROPFIND PROPPATCH MKCOL COPY MOVE LOCK UNLOCK #Order allow,deny #Allow from all # #Order deny,allow # #Deny from all #/Limit LimitExcept GET HEAD OPTIONS require valid-user /LimitExcept /Location -- Can anyone please help me with the following: --- * Compiling mod_perl and mod_dav staticaly together and ensuring apache does not die on any request or * Compiling mod_perl statically and mod_dav dynamically but getting apache to return the right Allow: headers so webdav actually works.

[ANNOUNCE] PHP::Session
Announcing new module: PHP::Session.
This module enables you to read / write (write is not yet implemented
though) PHP4-builtin session files from Perl. Then you can share
session data between PHP and Perl, without changing PHP code, which
may be a hard work for us Perl hackers.
This is something you'll never want to do, but imagine the cases where
you should co-work with PHP coders, or take over another company's PHP
code.
NAME
PHP::Session - read / write PHP session files
SYNOPSIS
use PHP::Session;
my $session = PHP::Session-new($id);
# session id
my $id = $session-id;
# get/set session data
my $foo = $session-get('foo');
$session-set(bar = $bar);
# remove session data
$session-unregister('foo');
# remove all session data
$session-unset;
# check if data is registered
$session-is_registerd('bar');
# save session data (*UNIMPLEMENTED*)
$session-save;
DESCRIPTION
PHP::Session provides a way to read / write PHP4 session files, with
which you can make your Perl applicatiion session shared with PHP4.
TODO
* saving session data into file is UNIMPLEMENTED.
* WDDX support, using WDDX.pm
* Apache::Session::PHP

Re: Problem comping mod_perl and mod_dav statically at same time...
Hi All, To all those that read the message and were about to reply, a big thankyou. I *think* i have it working :-) The problem was that the 'dav' directory (as specificied in the Location field in my httpd.conf) did not exist on the filesystem!!! Once i created that, all the options seem to be available, and the Allow headers is perfect. cheers, simran.

Apache and Perl with Virtual Host
Forgive me if I'm posting to the wrong group. Ive got apache 1.3.22 running several virtual webs. I can get perl scripts to run under the default web but not in the others. All the webs point to the same script folder. If I try to run the script under a virtual web, all I get is text display. Any help would be great. Thanks Matt
Re: Serious bug, mixing mod-perl content
Beta contains new code and www is old code. We were calling www but once a
while beta would pop in. We noticed error messages that were giving whole
stack trace (caller) but those error messages were not present in www code,
they are implemented as a change in beta code. Right now we solved the problem
by moving beta to a totally different domain. We'll make a large test
eventually. Everything seems ok, double checked with a help from my business
partner, the paths are different, names are different etc.
Could you describe the actual nature of the error? How can you tell
that the response you're getting is from the wrong virtual host and what
is different about the virtual hosts' setup that causes the difference
in responses?

RE: loss of shared memory in parent httpd
It's copy-on-write. The swap is a write-to-disk. There's no such thing as sharing memory between one process on disk(/swap) and another in memory. agreed. What's interesting is that if I turn swap off and back on again, 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)... 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. -bill

Funny, I'm doing this for ages and I never really knew why, you just
found the reason, Thank You! My concerns were similar to yours but on
a smaller scale, so I did not worry that much, but I'm running a
swapflusher regularly.
Make sure you have a recent kernel, because all old kernels up to
2.4.12 or so were extremely unresponsive during swapoff. With current
kernels, this is much, much faster and nothing to worry about.
Let me show you the script I use for the job. No rocket science, but
it's easy to do it wrong. Be careful to maintain equality of priority
among disks:
use strict;
$|=1;
print Running swapon -a, just in case...\n;
system swapon -a;
print Running swapon -s\n;
open S, swapon -s |;
my(%prio);
PARTITION: while (S) {
print;
next if /^Filename/;
chop;
my($f,$t,$s,$used,$p) = split;
my $disk = $f;
$disk =~ s/\d+$//;
$prio{$disk} ||= 5;
$prio{$disk}--;
if ($used == 0) {
print Unused, skipping\n;
next PARTITION;
}
print Turning off\n;
system swapoff $f;
print Turning on with priority $prio{$disk}\n;
system swapon -p $prio{$disk} $f;
}
system swapon -s;

[OT]RE: loss of shared memory in parent httpd
Call me an idiot.
How is it even remotely possible that turning off swap restores memory
shared between processes? Is the Linux kernel going from process to process
comparing pages of memory as they re-enter RAM? Oh, those two look
identical, they'll get shared?

RE: Problem With DB_File Installation On Red-Hat Linux 7.1 [OT]
I had this problem the other day. And it was a screwy problem to fix. I had to get the latest BerkeleyDB, something like v4.0.14 (www.sleepycat.com) install it. Then reinstall the DB_File and I believe Storable modules making sure they pointed to the new install of BerkeleyDB. Of course, when I went through all of this I screwed up rpm somehow and other parts of my system so bad I surrendered and wiped my machine (which is my development desktop) and loaded RedHat 7.2. I think that trying to figure out the problem I uninstalled some RPMs I needed. If I had CAREFULLY followed the instructions for installing DB_File that came with the 4.0.14 BerkeleyDB install I think I would have been ok. It has been a few weeks since I went through this and I have seen a squirrel or two since then and it was a bad experience so I have tried to block the memories of the awful awful day. I hope this helps, but I doubt it will. Good luck. -Original Message- From: James McKim [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 14, 2002 9:01 AM To: [EMAIL PROTECTED] Subject: Problem With DB_File Installation On Red-Hat Linux 7.1 I'm trying to install DB_File on our Red-Hat Linux. 7.1 box and am getting an error about having 2 versions of BerkeleyDB installed.

That rings a bell.

POST and multipart/data-form question
I have searched off and on for the past 3 weeks for a solution to my
problem. I am at wits end. . .and thought I would finally ask the
mailinglist.
I had a set of CGI scripts that worked without problem. I began the process
about 4 weeks ago of moving them to mod_perl. The suite of scripts are
handled as their own perlHandler collection. One of the scripts has a form
where a user can either enter data directly, or indicate a file of
equivalent data.
When I use the form to POST without any enctype and if you enter directly
into the form things work correctly. That is, the data is massaged and
sent back to you as downloadable file. Of course, this form does not handle
file uploads.
Now, I change nothing more than the form enctype to multipart/data-form.
Now, regardless of how the data is presented in the form (e.g. directly or
via file upload) the browser tries to refresh the screen with the web-page
(which it should not since its only response is to send to the client a file
to download). However, the web page does not get completely sent, and
consistently stops in the middle of the send.
I have been using the POST2GET snippet to help make the post more
persistent. In short, my httpd.conf file looks like:
#
# **
# ** MOD PERL CHANGES **
# **
# limit POSTS so that they get processed properly
Limit POST
PerlInitHandler POST2GET
/Limit
# force reloading of modules on restart
PerlFreshRestart on
# Perl module primitive mother load on start/restart
#PerlRequire lib/perl/startup.pl
# FLOE application (mod_perl)
PerlModule Apache::DBI
PerlModule floeApp
Location /floeApp
SetHandler perl-script
PerlHandler floeApp
PerlSendHeader On
/Location
And the relevant two snippets of code from the script are:
## process incoming
# if submitted
my %hash = undef;
my $initialList = $q-param('initialList') || '';
my $upload = $q-upload || undef;
my $fh = $upload-fh if defined($upload);
if (defined($upload) $upload) {
$initialList = '';
while ($fh) {
$initialList .= $_;
}
}
## some processing is done to the POST'ed data
## and eventually. . .
## send file to client

filename=list.txt\n\n;
foreach my $value (sort keys %$hash) {
chomp($value);
next unless ($value);
print $hash-{$value}$CRLF$value$CRLF;
}
exit;
Any ideas? I would love to get this solved so I can get back to developing
useful scripts. :)

Re: [OT]RE: loss of shared memory in parent httpd
How is it even remotely possible that turning off swap restores memory shared between processes? Is the Linux kernel going from process to process comparing pages of memory as they re-enter RAM? Oh, those two look identical, they'll get shared? This is a good point. I really have no clue how the kernel deals with swapping/sharing, so I can only speculate. I could imagine that it's possible for it to do this, if the pages are marked properly, they could be restored. But, I'll admit, it seems unlikely. ...and, I had this thought before. Maybe this apparent loss of shared memory is an illusion. It appears to make the amount of memory that the httpds use grow very high, but perhaps it is a kind of shared-swap, and thus the calculation I'm using to determine overall memory usage would need to also factor out swap. ...in which case, there's no problem at all. But, I do see an albeit qualitative performance increase and CPU load lowering when I get the httpds to stay shared (and unswapped). So, I think it does matter. Though, if you think about it, it sort of makes sense. Some portion of the shared part of the httpd is also not being used much, so it gets swapped out to disk. But, if those pages really aren't being used, then there shouldn't be a performance hit. If they are being used, then they'd get swapped back in. ...which sort of disproves my qualitative reasoning that swap/unshared is bad. my head hurts, maybe I should join a kernel mailing list and see is someone there can help me (and if I can understand them). -bill

On Thu, 14 Mar 2002, Bill Marrs wrote: It's copy-on-write. The swap is a write-to-disk. There's no such thing as sharing memory between one process on disk(/swap) and another in memory. agreed. 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 ? Stas also has some tools for causing children to exit early if their memory usage goes above some limit. I'm sure it's in the guide. -bill -- [EMAIL PROTECTED] | Courage is doing what you're afraid to do. http://BareMetal.com/ | There can be no courage unless you're scared. | - Eddie Rickenbacker
RE: Mapping files
Ok, I found an interim solution for my file mapping issue the problem I am running into now is that get/post data associated with the request is lost . . . Is this covered in the mod_perl cookbook? I am trying to map a uri to a file based on certain factors. I would like to have this done after the 'Trans' phase when certain information is available. I noticed when the original file mapping does not exist (what apache maps in it's 'Trans' phase) the 'content_type' method does not return a value. it shouldn't. mod_mime needs the filename the URI maps to in order to determine the MIME type. I actually found an initial answer after digging through the docs. After mapping the file I can create a new sub-request via lookup_file($filename) and take appropriate action. So far so good . . .

You are not access the hash with the proper syntax:
%Actions::Vars::config

Hi,
You should read the perllol documentation. It has got lots of information
about what you're talking about. This isn't a mod_per specific issue.
First of all:
the subhash you are referring to is just a value of the
%Action::Vars::config has. So you retrieve it like this:
$hashref = $Actions::Vars::config{$conf}
Now, that gives you a hash reference, from which you can access values
using $hashref-{key} ou $$hashref{key}.
If you want to retrieve the hash in normal form, like this:
my %conf = get_conf($conf);
You need to access all the values of the sub-hash.
So you get:
return %{$Actions::Vars::config{$conf}};
and then you can do:
my %hash = get_conf($conf); (or whatever)
This is actualle equivalent to:
my $hashref = $Actions::Vars::config{$conf};
my %hash = %$hashref;
Again, see perllol, it'll give you insight into this matter.

If your designers aren't making use of checkin/checkout in DreamWeaver, then simply make it clear to them that before they can save a file to the server, they have to do a sync first. Make the final repository sit on CVS, and do a checkin every night. So if something does go wrong you can at least pick up the previous day's work. 2. DreamWeaver's locking mechanism is handled by placing lock files on the server. Those files have the info about who has what. It ought to be possible to write an emacs extension that would use those files. -- Kee Hinckley - Somewhere.Com, LLC http://consulting.somewhere.com/ [EMAIL PROTECTED] I'm not sure which upsets me more: that people are so unwilling to accept responsibility for their own actions, or that they are so eager to regulate everyone else's.

Re: performance testing - emulating real world use
My experience with commercial load-testing apps is that they are outrageously expensive, a pain to program, don't really scale all that well, and mostly have to run on Windows with someone sitting at the mouse. There are some that work better than others, but the free stuff in this areas is quite good. Ditto. I've found it easier to hack together something with LWP's LWP::UserAgent and Benchmark. Particularly when load-testing an application that required different pre-registered users that had not performed this particular transaction we were load testing. (A survey with random and different questions - depending on the user!). None of the macro-like testing apps could do very much with regard to that kind of interaction and variability in the content generated by the application we were load-testing. But a 30-line Perl script that simply appended the Benchmark results into a tab-delimited file worked great. We found about 30 instances of Perl running the script per WinPC ate the machine. So we only loaded 15 per PC during actual testing and added more distributed nodes to the test. As an aside, the whole thing was an exercise in needing a cup of sugar and asking the local grocery store how much sugar they have on the shelves. i.e. What is the point of measuring beyond the more than the 1 cup you need? So we measured (at great expense) and determined that the entire lifetime load (~1yr) expected for all users on their system could be accomplished on the existing sytem during a lunch hour.

If I don't use the connect_on_init stuff, I can run a test script fine with those
exact db parameters.
Any suggestions?
Thanks!

Re: Apache::DBI startup failure
I've seen similar behavior with DBD::Sybase; if your SYBASE env variable
is not set or points at an invalid directory Apache starts up but begins
segging every child process over and over again.
I'm not familiar with Postgres but this might point you in the right
direction.

RE: [WOT] emacs and WEBDAV
At 11:30 AM -0800 3/14/02, Rob Bloodgood wrote: The problem is, concurrency. Dreamweaver has versioning built in... but emacs has no way to recognize it. So when I make a fix to a file, if the designers aren't explicitly instructed to refresh-from-the-website-via-ftp, my changes get hosed. Versioning, no. Locking, yes, optionally. (Well, I guess it can do versioning via SourceSafe, but not via anything else.) I'm seriously hoping they'll address that in the next release. sigh I meant locking. Not versioning. e-Foot in e-Mouth. Emacs over WebDAV should work fine if you run something that supports WebDAV as a filesystem (e.g. OSX), but that's not going to help you much. If we're talking about LOCKING, is this statement still true? There are two options I can think of. 1. If your designers aren't making use of checkin/checkout in DreamWeaver, then simply make it clear to them that before they can save a file to the server, they have to do a sync first. Make the final repository sit on CVS, and do a checkin every night. So if something does go wrong you can at least pick up the previous day's work. That (the train-them-to-sync-first part) has been what I've been forced to do so far. I haven't gone so far as to set up a CVS for the website tho. Thx for the, I'll look into it. 2. DreamWeaver's locking mechanism is handled by placing lock files on the server. Those files have the info about who has what. It ought to be possible to write an emacs extension that would use those files. Certainly. But my original message mentioned the REAL source of my frustration: I'm pretty limited at elisp, otherwise I might have already had this worked out. :-) L8r, Rob
Re: Apache::DBI startup failure
Ok, I found it, but this has got to be some kind of bug.
This works:
Apache::DBI-connect_on_init(dbi:pg:demo,demo);
This doesn't:
Apache::DBI-connect_on_init(dbi:Pg:demo,demo);
That's right, putting 'dbi:pg' in lowercase made it work. I looked through
some old newsgroup stuff and saw someone using Postgres had it similar to
that.
Here's some further debugging information for the developers:
perl -v = v5.6.1 on i386-freebsd (FreeBSD 4.4)
# pkg_info |egrep -i dbi|postgres
p5-Apache-DBI-0.88 DBI persistent connection, authentication and authorization

Weird, although I bet if you had straced the apache processes you would
have seen the File not found.
For some reason I recall DBD Drivers being case sensitive.

Looking for RPC::ONC.pm
Does anyone know where I can find an ONC RPC perl package? The only one I found is perlrpcgen-0.71a from Jake Donham who used be reachable at [EMAIL PROTECTED] However Jake's implementation requires an include file (rpc/svc_soc.h) that seems to be only available on Solaris. I need a linux version of it. I also see lots of XML-RPC and home made client-server RPC look-alikes. I need this to work with ONC RPC Server written in C.
