Yes.

If you used DSO you can just modify the httpd.conf, otherwise you need
to recompile Apache.

How to uninstall mod_perl?

[Brian Tully]

Please excuse my  naivete but how do I uninstall mod_perl?  Do i have to
recompile Apache? 

ARGV in exec subprocesses

[Edwin Pratomo]

Stas, the example you supplied in the miniguide 
(http://perl.apache.org/guide/performance.html#Forking_or_Executing_Subprocesse)
doesn't work.
It's because the scalar returned by FreezeThaw::thaw contains shell escape
chars, like: [|;] so system("program.pl $params") obviously will break.

If the argument we will pass to the external script is just a simple scalar,
regexing the arg is enough, like in a SIG{__DIE__} handler in my
handler.pl:

$SIG{__DIE__} = sub {
local $ENV{'PATH'} = '/home/myhome';
my $params = $_[0];
$params =~ s#\n# #gs;
$params =~ s/'/"'"/gm;
my $taint_safe = ($params =~ m#(.*)#m)[0];
system("alertall '$taint_safe'");
};

But if the arg is in a more complicated type, of course stringification is
essential, but then we have to make it safe for shell.
MIME::Base64 is the easy way for this, but probably a bit overkill :-)

Thanks for the excellent guide.

Regards,
Edwin.

I would be very happy to work together in this area, so extentions that
works with ASP will also work with Embperl and viceversa. I have a lot of
ideas (which also includes an interface like you describe). Just give me a
few days, before you start implementing this XML stuff and I send you a
description what I plan and we can discuss what you think about it and what
you like to change

ANNOUNCE: Apache::AuthCookie 2.001

[Ken Williams]

Hi,

The URL   
http://forum.swarthmore.edu/~ken/modules/archive/Apache-AuthCookie-2.001.tar.gz
has entered CPAN as

  file: $CPAN/authors/id/KWILLIAMS/Apache-AuthCookie-2.001.tar.gz
  size: 14968 bytes
   md5: 252ea4ec539f0c303ae552a4e25588d5


 - The login forms may now use the POST method instead of the GET method.
   This is a big deal, because with GET the user's credentials get logged
   to access logs, they remain in the user's browser history, and so on.
   Thanks to [EMAIL PROTECTED] (Eric Cholet) for the patch and prodding.

 - There is now a proper test suite, which will fire up an httpd and make
   requests of it.  The test code is adapted from Eric's old example
   (eg/) suite.

 - I've added a logout() method to help unset cookies.  The example
   logout.pl now uses logout().  Thanks to Aaron Ross
   ([EMAIL PROTECTED]).


These are 3 pretty important additions.  Let me know how they pan out.

You can't keep Embperl from doing so, but that isn't really the problem. The
problem is that you have to tell Apache to generate the error page for you.
In a Apache::Registry script you can do this by

sub notfound
{
return 404 ;
}

but this isn't possible within a Embperl page. So either use
Apache::Registry for that purpose, because you won't display any HTML
anyway, or use your code above and generate your own errorpage, instead of
let Apache do this for you. This should work quite well

A number of the lines are 5-6K each.  Context is a rather large

With buffering on or off, and max "segment" size of 900 bytes in any
one call to print() (or $r->print()), but doing 120kb worth of
printing in rapid succession, the smaller-but-still-large delay shows
up typically around 100kb into it.  The only way I was able to make
the large delays disappear so far is to sleep 1 every 50 prints or
so...but that's not really disappearing, now is it...

Experimentally, it appears this is simply too much data too quickly. 
I think I've seen $|=1 make a big difference with other non-local
NT/MSIE clients, even on these 120kb pages.  I've consistently been
able to reproduce this problem in both buffered and non-buffered mode
with linux netscape 4.7, both locally and remotely.

I'll look into the kernel buffer issue... :(

This is off-topic for this list, but I can't resist...

What's the benefit of using XML?  You get to buy expensive application
servers! No, that can't be it...  You get to buy a bunch of books on XML! 
No, that doesn't sound right either...  It's an excuse to learn Java!  No,
somebody went and wrote a Perl parser...  It's a way to store structured
information like a database system, but without all that pesky concurrent
access management and query capability!  No, there must be something... 

Well, it's from Microsoft, so it must be great!  Right?

Okay, I admit there are places where XML is useful.  Any place you used to
say "comma separated values" can be s/// with XML and improve the
readability of your data.  It makes nice-looking config files too.  It's
very handy when you need a format for passing complex data in an OS and
language independent way.  It's also handy when you don't know what your
data structure will be before you start, so you can't make a real database
schema for it.  Witness the folks at http://www.allaire.com/ who built an
entire product (Spectra) around serializing objects in a single field as
XML.  Of course, if you only need to manipulate data using perl, you could
just serialize with Storable and save some space/cycles.  It can also be
used when you want to store some structured data but you can't run a real
database for some reason.  It definitely beats making up your own addition
to the million or so text-based data formats out there. 

Some people like to pull data from a database, turn it into XML as an
intermediary format, and then use something like XSLT to turn it into
HTML.  Personally, I don't see a good reason to do this instead of
just using perl's internal data strutcures for your intermediary
format and using something like Template Toolkit (see CPAN) to format
it into HTML.  But, it's a matter of taste, and also of portability to
other languages.

Looks I came up with some reasons after all.  So go ahead and use it if
you see a fit.  Just don't believe anything that a person with a product
to sell tells you about XML.  Or anything else.  But that's a different
story.

Yeah, I just saw the message.  Since I tend not to use CPAN.pm (I like to

How about this: for Apache::AuthCookie I've been writing a system that will ask

$ENV{APACHE} or '/usr/lib/httpd/httpd'.

$r->content_type clobbering outgoing headers

[Aaron Ross]

Hi!
 
 I have an access handler that uses $r->headers_out->add to add a set-cookie
header:

  $r->headers_out->add("Set-cookie"=>$sesc);

 If i try to access this in my ContentHandler, actually HTML::Mason, i find
a strange problem: Calling $r->content_type wipes out the header!

>From the handler.pl:

 sub handler
 {
my ($r) = @_;

$r->headers_out->do(sub { my ($k,$v) = @_; $r->log_error("OUT: $k=>$v"); 1; });

return -1 if -e $r->finfo && $r->content_type && $r->content_type !~ m|^text/|i;

$r->headers_out->do(sub { my ($k,$v) = @_; $r->log_error("OUT: $k=>$v"); 1; });
 
  snip 

 }

 The first do call works fine returning something like this:

[Thu Feb 10 12:11:47 2000] [error] OUT: Set-cookie=>MF_Session=14&950202707; 
domain=.mathforum.com; path=/

 The second returns nothing at all.

 Commenting out the content-type line fixes the problem... However, I like
that line and want it to stay!!!

Re: exit signal Alarm Clock (14)

[Bill Moseley]

Still still trying to figure this out:

I get about 10 or 20 exit signal Alarm Clock (14) messages a day -- out of
15,000+ requests.  Not very many.

I log the PID of my mod_perl script each request, and for each 'exit signal
Alarm Clock (14)' there seems to be a mod_perl request about 5 minutes and
two or three seconds before the time of the Alarm message in the main log
file.

The Apache Timeout setting is 5 minutes.

So it would seem that my mod_perl script is somehow not restoring
$SIG{ALRM} in some cases, even though it's localized in an eval block.
That is, the Apache Timeout is triggering an alarm, but there's no handler
to catch it.  I'm always calling alarm( 0 ) after exiting the block.

I have failed to duplicate the error message on a test server.  I've tried
a server with only one child process, running the mod_perl script, then
running another mod_cgi script that just sits for longer than the Timeout
setting.  But it times out as expected without killing the process.

I could try using Sys::Signal, but I understand that's not need with
$SIG{ALRM}.  Besides, I do see other normal timeouts (e.g. send body timed
out) in the server log file.  So it's not happening all the time.

Any suggestion on what else to look at?

BTW -- I did remove the CORE:: from CORE::sub {} as Stas suggested.

   Yeah, given enough scrutiny and/or experimentation, none of these sorts
of problems are difficult to solve, specifically. But it takes time to
sort all these things out, which is why having good, accurate

Your config looks fine.  Apache::Filter when loaded should
define the filter_input method.  Try preloading Apache::Filter 
with "PerlModule Apache::Filter" in your httpd.conf, and perhaps
also try preloading Apache::ASP.  Apache::ASP should load
Apache::Filter automatically in this case, so your results
seem odd.

Question, does the ./site/eg/ssi_filter.ssi example work
for you?  Then we probably just have a config problem here.

Re: $r->print delay?

[Ken Williams]

What context is this in?  Are you using anything like Embperl, Mason, etc. that
might buffer the entire output in order to find the content-length?

Any difference if you change it to print() instead of $r->print(), or if you
break it into lines and print each line?

Actually, I bet that last trick might work.

How do I send a 404 from Embperl?

[Alan Gutierrez]

I am attempting to send a 404 not found message from an Embperl script. Here
is the code I am trying to use in its simplest form. This is test.html. Note
that it contains no HTML.

[-
  $req_rec->status('404');
  $req_rec->header_out('Content-Length' => undef);
  exit;
-]

Normally, a 404 looks from Apache looks like this:

GET /monkey.html HTTP/1.0

HTTP/1.1 404 Not Found
Date: Thu, 10 Feb 2000 20:43:34 GMT
Server: Apache/1.3.9 (Unix) mod_perl/1.21
Connection: close
Content-Type: text/html



404 Not Found

Not Found
The requested URL /monkey.html was not found on this server.

Apache/1.3.9 Server at sauron.mindsinc.com Port 8386

Connection closed by foreign host.

I left the "Connection closed ..." so we could see where exactly the
documents end.

Here is the output from test.html:

GET /mtn-dev/resources/test.html HTTP/1.0

HTTP/1.1 404 Not Found
Date: Thu, 10 Feb 2000 20:40:17 GMT
Server: Apache/1.3.9 (Unix) mod_perl/1.21
Content-Length: 2
Connection: close
Content-Type: text/html


Connection closed by foreign host.

Oh! So close! But the Content-Length makes the client think that there is
something worth displaying. Both NS and IE show a blank page. What I'd
rather see is the server's error page.

The question: How do I keep Embperl from adding the content length to the
headers when I want to send an error message?

You don't say how many lines your 120kb of data is. If it's about 40
characters per line average that's 30k calls to write (because you turned
buffering off). Calls to write ought to be around 100us but if they were slow
for some reason and took 500us then that would explain the 15s.

Additionally you're probably filling the kernel buffer and forcing a context
switch several times. If the buffer is about 4k then there would be 3k context
switches each about 10ms on linux, or about 30s of latency. There was a debate
over the usefulness of the ProxyReceiveBuffer parameter, and even that isn't
the same as this buffer, but it ought to be possible for Apache to setsockopt
to ask for a larger buffer.

In short, don't set $|=1, it will only slow down this process, and investigate
if there's any way to increase the size of the kernel buffer for the socket in
Apache. Lots of people would be interested to know if you turn up anything
there.

   This would be cool. However, in at least a few cases, the PHP docs leave
something to be desired. I remember looking up the Oracle connect calls for
PHP online once (for 3.0), and having people hold a debate about how a
function really worked, because the docs were wrong, but no one really
knew what was right--one guy would say, "I think it really returns THIS," 
and another would respond with, "No, I think it returns THAT." Gives you a 
nice warm and fuzzy feeling about quality of documentation... :)

Of course they could have just resolved it by looking at the source :)

Re: $r->print delay?

Are you sure it's waiting?  You might try debug timestamps before & after the
$r->print().  You might also be interested in the send_fd() method if the data
are in a file.

Fairly certain it's waiting there.  I cut my debug timestamps out for
ease on your eyes in my earlier post, but here's one output (of many
like it) when I had the print sandwiched...

Thu Feb 10 14:41:59.053 2000 [v1.3.7.1 2227:1 ed:1]  INFO : Sending

Re send_fd(), it's all dynamically generated data, so that's not an
option...

Other clues?

hi all!

 the problem is me. the handler works fine with a full, existing path. the

 basically, i need to handle setting cookies with a redirect, then this 
problem along with a related one for images go away.

Apache::ASP and Apache::SSI problems

[ericb]

Okay, I installed mod_perl, Apache::ASP and required modules like 
Apache::Filter, and Apache::SSI.  (Note, some of the Apache:: modules will
not isntall via CPAN.pm, they look for HTTP in some messed up directory
where it oviously doesn't exist, you have to run make install manually or
force the install through cpan which I have NO IDEA how to do).

Anhow, Apache::ASP works fine, mod_perl works fine, no complaints from
anyone.  However, Apache::SSI will not run on top of Apache::ASP.

Here is my statement:


SetHandler perl-script
PerlHandler Apache::ASP Apache::SSI
PerlSetVar NoCache 1
PerlSetVar Global /tmp/
PerlSetVar Filter On
PerlSetVar Dynamic Includes 0
PerlSetVar StateDB DB_File
PerlSetVar GlobalPackage main
PerlSetVar Debug
PerlSetVar UseStrict 1


And in error_log I get the message  
[date..] [err]r Can't locate object method "filter_input" via package 
"Apache" at /usr/lib/perl5/site_perl/Apache/SSI.pm line 28

I just installed all the modules off CPAN yesterday.

I have a distinct feeling that mod_perl is not configured
properly.  I let CPAN do the installation and I put 
AddModule mod_perl.c
in my httpd.conf.
Is there anything else to do? 

PS I am running apache 1.3.9
PPS I am downloading 1.3.11

??? Proxy request order

[Clifford Lang]

I have a production UltraSparc-1 server running Solaris 2.5.1, Apache-1.3.9,
mod_perl-1.21, MySql, (168mhz, 512MB ram). I am at the edge of memory usage,
and occasionally even swap (bad I know).

I don't have a development box so I want to try something with out breaking
whats working already.

I want to leave my core server alone, but insert a proxy rule for all
^/images/ on my server and redirect them to a light weight Apache server
running on the same box.

The average memory "RES" is 6-7Meg per child.  I remember running a light
weight sever before and it was just over 1Meg each.


Now - to my real question:  
Is this order big-server -> little-server going to benifit me much?  Would
just a simple ReWrite proxy rule do it?  I know the normal order would be
little -> big, but I think thats a bit risky at this point.

TIA,  Cliff

PerlDispatchHandler for error handling?

[David Harris]

Hey,

Does anybody know how to use PerlDispatchHandler to somehow trap errors in
perl? I think I remember somebody mentioning that... I've been looking around
and I can't find too much of any documentation about what PerlDispatchHandler
actually does. (Already checked the archives and www.modperl.com.) Anybody know
what actually PerlDispatchHandler does? :-)

But you can test it trivially.   Just set up the "little" server on an
alternate port.  Once you have it working and are satisfied, just
switch the ports on the config files and restart the httpds.

A while ago somebody posted that they were working on an open source shopping
cart using mod_perl. Did anything come of that?

I'm wroking with minivend right now and, well, it's not very nice.

What would be nice is to have a perl Minivend API (since it's so full-featured)
so you could create your pages with Embperl, ePerl, Apache::ASP, etc and still
use the MiniVend backend.

at the very least, you should move mysql to a separate box, anyway.
3-tiered architecture should include physical and as well as logical
separation of presentation/logic/data/.

There are a couple of things to look out for.

For one, if you have multiple databases and you use persistent
database connections you'll quickly run out of your connections.
Assuming you have 4 different databases and 50 processes, it
doesn't take many requests to reach 200 database connections.
Disable persistent connections in that case. MySQL doesn't take
much of a performance hit without them anyway.

The number of connections your MySQL database can handle is
highly dependant of a lot of things such as the number of
tables you're using. Out of memory I believe it needs a
couple of file descriptors for every n tables that a
connection opens. (See docs for specific details). There
will be a time you run out of file descriptors ... I've
seen a properly configured server handle up to some 200
simultaneous connections [not queries, mostly idle
connections] I vaguely recall. But you really do want to
try to get that number down as best as possible.

You can gain quite a bit of performance by (a) bringing the
number of queries down and (b) making sure all your queries
have proper indexes. Try not to make a crazy amount of
updates either, as that means that your indexes have to
be maintained as well.

If you have very varying database needs (such as one db
with sessions, very frequently updated but tiny amounts
of data, and another with large sets of data that's hardly
ever updated) you might be able to gain a lot by running
two differently configured databases on one server. One
would benefit from lots of caching, the other would
probably reduce the efficiency of the cache but would gain
from fast disk access. Different usage profiles require
vastly different performance needs.

Basically consider every SQL query you have to do as one
too much. :) Using a module like HTML::Mason allows you
to cache the output of your page for a specified amount of
time, for example. If your page needs nothing more than an
hourly update but you have to do 15 queries to build it
and it's often accessed, Mason's caching might be a lot
faster instead. Besides, it will take some load off our
database as well, which might or might not be good
depending on your situation.

Grtz,
Pascal

I guess you could do a httpd -X, or is there another way?

Take a look at Apache::Scoreboard it knows to fetch the scoreboard info
from remote server. I guess in the same fashion you can write a module
to
connect and retrieve other data as well.

But wait, why not to write a script/handler that will deliver all the
required data on request? Use LWP for retrieval and Storable or/and
Data::Dumper for easy serialization and later restore.

For speed, I like to use Lynx but it's a pain with sites that have

they are often not navigable with Lynx.

My guess is that it's your code that's tempermental.  See

Sound like you're not asking the database for the new values.  Time to
do some debugging.  It's in the Guide.

I'd think about upgrading both, maybe after the 2 Feb CERT patch for

Plus using Mason to cache components to reduce the number of queries or
any other method to cache the query results. I think you can also run more

Robin, I thought it happens only in Israel :) I hope you are free now. I
went free on this Sunday. Hooray!!!

Great document! Seems great to me!

Won't it make the index.html overloaded?

Ged, I and probably Andrew will work on restructing the guide to improve
the structure and navigatability. But this after Ged completes the review
of the current chapters more or less, and me inserting the long list of
items from my todo list.

Everything is generated from the POD sources. I'll tweak the output
generator as you will like, to make the look and feel consistent. 


BTW, you didn't mention a usage of CSS files to enforce the look and feel. 

> - mention Stas' guide + Eric -> book

Please don't forget Eric, he works harder than me, but you cannot see that
before the book gets published. The news item at the demo page doesn't
mention his name. Thank you!

Yup, I've hacked the original pod2html, which I use in the guide. You can
use it. Another code to use is the Site::Builder that I wrote for the
Source Garden. It knows automatically generate htmls from .pod, .prepod
(item lists + pod) and .txt -- see
http://modperl.sourcegarden.org/safari/modperl/-/-/site_builder/

That's something that Fresh:: modules should cope with when James
completes them. They will serve the sourcegarden goal to make all the
stuff generated from the DB. The intention is to remove all the static
pages (from the perl.apache.org) that would benefit from the
administration speedup.

Be careful with PNG as they kicks off my older Netscape browser on linux!

I think what you wanted/need to write here is a lynx compatibility for
the impared folks and those who prefer text mode browsing.

Thanks Robin!!!

Re: [SITE] possible structure suggestion

[Stas Bekman]

Please decide whether you want to have the discussion at the mod_perl list
or its sister advocacy list. I've added the advocacy list to CC, so at
least the person who will search the advocacy archive in the future will
find all the info about this important issue. Therefore I quote it in all
completeness here.

TomC, please don't tell me that I don't know how to quote. Thank you!

What's the benefits of using XML ?

[Vlad Safronov]

What's the benefits of using XML in building web site with dynamic
content?
(web site is a front end to database)
