mod_perl2 custom form handler and Motorola i530 phone
This is likely not a strictly mod_perl2 problem, but I'm not finding resolution elsewhere. I have written a custom form data submission parser for our site. Admittedly, not one of my wiser decisions, but it works .. until now. We have a customer trying to use a Motorola i530 phone with a portion of our site. Besides not accepting cookies, this phone is doing truly strange things with the form submission data. When we pull the form data, the field names have doubly-escaped 's and /s surronding the name in the form of %2527 and %255C. It's also putting in /' sequences before the requested URL like so .. /'/'/'quote.html Would a more 'standard' form parser alleviate some of this or is this just a broken client. I really don't want to introduce a more heavyweight module just for this. Thank you for any guidance that could be given. Rodger

This helped me to get a workaround. I run configure through a front-end script and so for Linux and Solaris Apache2 config I get this to edit the lfs64 defined onto the EXTRA_CPPFLAGS (there being no other way to get anything into this variable). Then things work. It was odd to see that the core_dir_config struct was affected, as it didn't seem to contain anythign file-related, but it turns out that the rlim_t (in struct rlimit) changes size according to lfs64. I actually use Perl to get my compilation options for Apache (since I'm going to add mod_perl to it) but Perl puts the lfs64 settings onto CFLAGS rather than CPPFLAGS. lib/Apache2/Build.pm has some comments about how Perl and Apache build 64-bit fs versions. It states: # This is why it is a really terribly silly idea to ever # use approach (1) in anything other than an entirely self-contained # application. (approach (1) is using "-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64") I would disagree totally. Approach (2) was called transitional for a reason - it was what you could use while vendors transitioned their header files to make approach (1) work. Well written code can use approach (1) (and hence the same code can produce 32- or 64- bit versions just by changing the compialtion options). The binaries resulting from both approaches is basically the same - it's just the code you write which differs,

More connections means the machine is doing more work and running more processes, so of course it will be slower.

preloading modules in mp2
Hi, Has anyone experienced a slowdown in the start and stop times of the server when modules are preloaded? It takes more time to preload under mp2 than under mp1. mp2, preloading no modules: start and stop times are on the order of a second or less mp2, preloading modules listed below: start time is about 10 seconds and stop time is about 5 seconds. mp1, preloading no modules: start and stop times are on the order of a second or less mp1, preloading modules listed below: start time is about 5 seconds and stop time is about 1 second or less. Modules preloaded for the test --- use Apache::DBI (); use DBI (); use Fcntl (); use File::Copy (); use HTML::Parser (); use LWP::Simple (); use MIME::Lite (); use XML::Parser (); use XML::Parser::EasyTree (); use Encode (); use Archive::Zip (); use PDF::API2 (); use Digest::SHA1 (); Preloading more modules results in more of a difference between the two environments in regard to the start/stop times. These tests were done on a sun box running Solaris 9. Is there anything that can be done to speed this up or is this just the nature of mp2? Thanks for any information you may have, Ted

So it would seem this is a circular reference right?
How can I get the info I need in each of these without getting caught by this?
What are you trying to tighten up? Are you still just trying to get rid
of the warnings on shutdown?
Yes getting rid of the warnings, would help me sleep better...
The phases of request handling are documented pretty well on the site
and in various mod_perl books. The interpreter won't be shut down until
the process exits, but that may be long before the server is shut down
for a particular process.
I've been using O'reilly books in particular the books in The Perl CD Bookshelf v3.0.
They mentioned an "experimental" WeakRef module for weakening references
to prevent the circular logic thing. But I usually try and have my modules be the
only "experimental" parts of my apps if possible. I just found 13.13. Coping with Circular Data Structures
in the Perl Cookbook, maybe that has my solution.

When an object goes out of scope, it gets DESTROYed. This isn't the
whole parent process we're talking about, just one object.

That's the major worry with circular refs, so if you don't see that, you

Loading module into apache
Hi All! I'm sorry if this is the wrong place to post this question, however I failed to find more suitable mail-list for Apache-releated questions. I've downloaded and compiled Apache 2.0.54 with "mod_example", to take a look. When I tried to load the module into my already running server (which is 2.0.54 too), I received the following error: Syntax error on line 1 of /etc/apache2/mods-enabled/example.load: Cannot load /usr/lib/apache2/modules/mod_example.o into server: /usr/lib/apache2/modules/mod_example.o: only ET_DYN and ET_EXEC can be loaded Any help will be really appreciated! -- -- Максим Слойко begin:vcard fn:Maxim Sloyko n:Sloyko;Maxim email;internet:[EMAIL PROTECTED] tel;work:231 22 66 ext. 208 tel;cell:+7(905) 767 23 82 version:2.1 end:vcard

As an aside, are there rules of thumb about what cache works best in various situations? Are RDBMS's, if accessible, generally a good solution? Is there a document/link giving a comparison?

I would expect none of these solutions to work:
1. Solution:
-
Where from should perl know which port you are refering to / interested
in or turn it the other way round what happens when you server listens
to more than one port on more than one IP addresses?
- ---8<-
Listen 192.170.2.1:80
Listen 192.170.2.5:8000
- ---8<-
I haven't read the HTTP-API docs of this function but in short this API
doesn't make any sense at least it should return a List and not a Scalar.
2. Solution:
-
Where from should perl have a request in the startup-phase? The API in
request-context makes sense because an request is really made to one port.

You want is retrieving configuration values which can be done using
Apache2::Directive:
startup.pl:
- -8<-
use Apache2::Directive;
my $tree = Apache2::Directive::conftree();
my @ports = $tree->lookup('Listen');
foreach( @ports ) {
print "The server listens to port: $_\n";
}
- -8<-
httpd.conf:
- -8<-
#
#
PerlPostConfigRequire conf/startup.pl
- -8<-

Re: maintaining shared memory size (was: Re: swampedwithconnection?)
> Does this sound like fixing the wrong problem? Yes. Put a reverse proxy in front of your server, tune MaxClients so you won't go into swap, and then benchmark to see how much load you can handle. Then think about tuning. Thanks for replying... I have put a reverse procy in front of my mod_perl servers and I have set MaxClient to 30. I have tried setting it to 50, but it slows down the response time. This is what top gave me when I hammered the test server with httperf: -- top - 17:24:27 up 34 days, 9:01, 4 users, load average: 20.67, 12.84, 9.26 Tasks: 142 total, 7 running, 135 sleeping, 0 stopped, 0 zombie Cpu(s): 88.7% us, 7.6% sy, 0.0% ni, 0.0% id, 2.0% wa, 0.0% hi, 1.7% si Mem:906736k total, 359464k used, 547272k free, 6184k buffers Swap: 3036232k total, 111564k used, 2924668k free,17420k cached PID USER PR NI VIRT RES SHR S %CPU %MEMTIME+ COMMAND 22802 www-data 15 0 39664 35m 7968 S 30.7 4.0 0:05.02 apache-perl 22370 www-data 16 0 39664 35m 7968 S 12.8 4.0 0:03.45 apache-perl 13604 www-data 17 0 40096 35m 7968 R 5.7 4.0 0:30.93 apache-perl 15424 root 15 0 32060 7668 1560 S 3.8 0.8 6:49.47 memcached 13611 www-data 15 0 40036 35m 7968 S 3.5 4.0 0:17.13 apache-perl 22804 www-data 17 0 39664 35m 7968 R 3.1 4.0 0:03.01 apache-perl 13612 www-data 16 0 40032 35m 7968 S 0.7 4.0 0:33.38 apache-perl I ran httperf to create 50 connections.

It seems that the more connection there is, the higher the avg reply time. Does anyone ever experienced this? Why does it happen? Basically I just want to make my webapp ready to launch...
