We use BSD::Resource for our mod_perl clients. Keeps them
from eating the machine alive.
On another shared machine each client gets their own
interpreter with some pretty tight limits on child
spawning, open children etc. on top of the Resource limits
Shared hosting mod_perl is a real drag to
I have have had about 50 dual CPU/1GB ram boxes running a
combo of linux/freebsd over the least few years (20
currently). All running modperl/apache.
I always go Dual-CPU. Its not that pricey. We have had no
SMP problems at all and I think it performs much better,
about 30% higher
This brings up a good point, is there a list of 'ModPerl
Orphans' anywhere? For the most part I would imagine that
a modules author/maintainer will manage the transition to

with little hope of making it over unless some kind

That said, Kudo's to yahoo for being this public about it.

We felt the same way but once we went to CVS we never
looked back and can not imagine going with out source
control. It may seem like the web doesnt fit that paradigm
but if you break your modules up properly it works like a
champ.
We broke out into 'html','components',
Just give each developer their own sandbox.
We have gone from :
1 Apache proxy/1 modperl server
to
1 apache proxy / 1 modperl per developer running out of
their homedirs
to
each developer gets their own proxy and modperl.
If you tune your apache min/max server stuff this is quite
doable.
We use CVS to do in-place upgrades on the live system for
smaller updates.
For the big stuff we bring the boxes out of their pools
one at a time and upgrade them.
In both cases, the worse case is that a user might see two
versions of the same page in the span of 60 seconds if
they catch us

We check in all of our perl modules into CVS and its a

We are using IPC::MM and it works great. We use it to
cache about 5000 strings for our internationlized systems

pretty easy, in our startup handler we have :
my $MM_SIZE = 500;
my $MM_FILE = 'st_cache_mm_file';

Confirmed, but its browser dependant.
IE on Mac OS X sends the file but munges the filename. So
they file arrives fine but with the wrong name.
Mozilla on Mac OS X doesnt even send the file.

Hi All-
We are using Apache::Request to handle our uploads
via the browser. Now that we switched to UTF-8 encoding
any filename with Kanji in the filename uploads with a
size of '0' and nothing goes to disk. Take the same file,
put its name to roman chars and it uploads fine. All other
Make proxy and mod_perl have the same document root.
Use mod_rewrite on the lightweight proxy to serve certain
directories from itself rather then passing them back to
modperl (have it server images while you are at it)
Upload files to the directory specified above.
Result : File is uploaded
On the Apache 2.0 note, 2.0 breaks terribly when it has to
proxy chunked data. It strips the chunk length and does
not replace it with a Content-Length.
Bug is filed but no one in the Apache group seems to want
to play with it :(
Just a warning for those of you who may potentially be
doing
We do see some slowdown on our langauge translation db
calls since they are so intensive. Moving to a 'per child'
cache for each string as it came out of the db sped page
loads up from 4.5 seconds to .6-1.0 seconds per page which
is significant.
Currently we are working on a 'per machine'
We are investigating using IPC rather then a file based
structure but its purely investigation at this point.
What are the speed diffs between an IPC cache and a
Berkely DB cache. My gut instinct always screams 'Stay Off
The Disk' but my gut is not always right.. Ok, rarely
right.. ;)

Thanks, you just saved us a ton of time.

I havent had much luck with that but we will look at it
again and see what we can get from it. We want to avoid
preloading all data per child direct from the database but
I wouldnt mind doing it on startup for the root process
and then copying it to each child.

We built our own RPM that did source level builds on our

So you load the rpm and it in turn executes a build script

needed, compiled external binaries, installed the

Are you hitting the page directly? If so then you will not get a referer.
You have to link to it from another page in order for that variable to be
set. If the page is the first to load in the browser there is no referring
page.
Just a thought!
