 Nevertheless, in benchmarks we ran we found forking qmail-inject to be
 quite a bit faster than Net::SMTP.  I'd say that at least from a
 command-line script qmail-inject is a more scalable approach.

Or even better would be to use qmail-remote and avoid the queue, but
thats a qmail and not a mod_perl thing.

BTW I'm looking at this at the mo and have decided to go back to a dump
email to db - crond robot sends mail to port 25 - mail delt with
there.  Why ? Well this is the most scalable, and its cross platform,
talking directly via pipes / forks etc usually has a limit somewhere,
and all too often I may reach it far sooner than I thought.

Re: SELECT cacheing

2000-09-10 Thread Greg Cope

Brian Cocks wrote:
 
 I'm wondering how much improvement this caching is over the database caching
 the parsed SQL statement and results (disk blocks)?
 
 In Oracle, if you issue a query that is cached, it doesn't need to be parsed.
 If the resulting blocks are also cached, there isn't any disk access.  If the
 database is tuned, you should be able to get stuff out of cache over 90% of
 the time.  I don't know what other databases other than Oracle do.

Oracle is clever in this respect - and you are right if you tune
correctly you should hit the cache ...

But may other DB's do not have a shared executition plan / results
cache.  MySQL, msql and postgreSQL do not.  As far as I am aware Sybase
only has an execution plan cache that is per connection (could be wrong
here).

The MySQL developers have got a SELECT CACHED idea, where you can define
a statement as cacheable, and further calls to SELECT CACHE will return
the cached results - this is all on the todo list with no fixed date.
 
 What are the advantages of implementing your own cache?  Is there any reason
 other than speed?

Could be wrong but no - and it has a bad point in that it introduces an
added layer of complexity .

I am certainly interested as accessing a local cache should be an order
of magnitude faster than asking a buzy DB.

Mysql+Modperl?

2000-09-10 Thread Antti Linno

Hi.
I installed Apache_1.3.12, mod_perl-1.23 flexible way, also PHP4 as
module. I am using mysql-3.22.32(from source) and postgresql. Also perl
modules DBI-1.14, Msql-Mysql-modules-1.2214 .
Some minor problems during first install with php, but second time all ran
without any errors. Apache started nice, php test phpinfo() ran too.
Also HTML-Embperl-1.2.1 . As its my job to write scripts under Embperl, I
tested Embperl without database connections, everything worked nice.
Then I made small script to test database connections:
html
body
[-use DBI;
$dbh=DBI-connect("DBI:mysql:database=test","root","");
$kuupaev=($dbh-selectall_arrayref(qq{
select now()}))-[0][0];
$dbh-disconnect;-]
No mingi ilge jama BR
[+ $kuupaev +]
/body
/html
I got an empty document(errormessage). I included that error from
errorlog(below).
With postgres,it worked nicely. Tried different Msql-mysql-modules, but
without success. When I built mod_perl statically with Apache(the first
step in installation guide :), script worked nice. 
Btw, I tried it as pure perl script(removed all unnessecary tags),
DBI:mysql worked nicely and gave right answers.
So, it comes to my mind that there could be one of five problems:
Broken
1. Apache_1.3.12
2. mod_perl-1.23
3. Msql-Mysql-modules-1.22xx
4. DBI-1.14
5. mysql-3.22.32

Error log contains only:
 [Sat Sep  9 21:49:01 2000]
[notice] child pid 25528 exit signalSegmentation fault (11)

Is there a way to build mod_perl statically(later add Embperl) but with
PHP4 ? 
Main goal is to build a hybrid environment PHP4+Embperl-Mod_perl and
databases mysql and postgresql.

Greetings,
Antti





Memory leak hell...

2000-09-10 Thread Matt Sergeant

For 2 days solid now I've been trying to track down a very bizarre memory
leak in AxKit.

I've checked everything I can think of - all circular references are now
gone, all closures clean up carefully after themselves, and I've reduced
the usage of some external modules. But still the processes grow.

Now to the wierd bit. I could track this down if it wasn't for this:

The memory leak starts after the Nth hit, usually around 35. This is
running under httpd -X.

So it goes along very happily for 35 hits - memory usage is rock solid
stable. Then after the 35th hit the memory usage starts to grow about 4k
per hit. Obviously thats an impossible rate of growth to sustain for any
amount of time, and soon the server is swamped.

Can anyone give me _any_ help in figuring out where this might be coming
from? I've tried several things, including adding the ability to display
the memory usage in the debug statements (by getting the VmSize out of
/proc/self/status). This is driving me absolutely mad, as you might
tell. The only thing I can come close to in locating it is some remote
possibility that it is in one particular section of the code, but that
doesn't actually seem to be the case - sometimes the memory increase goes
outside that section of code.

The modules I'm using are:

Time::HiRes, Apache::* (core apache stuff only), AxKit, Digest::MD5,
Compress::Zlib, Fcntl, XML::Parser, XML::XPath, Unicode::Map8,
Unicode::String, MIME::Base64, Storable (loaded but not used),
XML::Sablotron (loaded but not used).

mod_perl is 1.24 and Perl is 5.00503 (Mandrake release).

First, Apache::VMonitor and GTop will make your debugging work much
easier. 

Second, The only reason that I can think of that things start happening
after Nth hit is that one of the modules that you use does an internal
accounting that goes astrey after Nth hit. Using Apache::Peek will help
you discover the leakage by dumping and comparing the complete package
variables tables. You will find some examples of using Apache::Peek in the
guide. This will definitely allow you to spot the offending module. Of
course the complete list of loaded modules can be found in /perl-status :)

Apache::Leak is another thing to try, but it's not really good unless you
know the exact offensive code. Otherwise it reports leakages for things
which are Perl optimizations in fact.

Yet another thing I'd think about is monitoring the code with GTop, and
running it under strace/gdb. So it goes like this:

You run a daemon that watches the processes and prints its memory size via
Gtop. You complete 35 hits and now run the server under Apache::DB 
debugger. So you do 's' by 's' (step by step) and watch the printouts of
the GTop daemon. Once you see the growth -- you know the offending
module/line - and voila... of course this should be automized...

And while you work on this it would be really really cool to have this
documented. I can imagine that you will have to write a few snippets of
code to automate things... But this would be a treasure for those in the
same trouble like you.

Hope this helps.

When I'm working on problems like this, there are two basic things I
try.  They're not rocket science, but they usually work.  The first is
removing sections of code until the leak goes away.  Then you get to
tear your hair out wondering why that subrotuine leaks, but at least
you'll know where it is.  The second is to run under the debugger, with
top running in strobe-light mode (refresh 0) in another window, watching
for which line pushes the memory up.

You've already named the usual suspects - closures and circular refs -
but some closure problems can be very subtle.

There's also the memory-related stuff that Apache::Status provides, but
I found it difficult to get useful info out of it.

[ RFC ] A Session Manager module

2000-09-10 Thread Greg Cope

Dear All

As some of you are aware for the past few weeks I have been working on a
Session Manager style module.

It works (ish ;-), I know of a few issues (that may not be important
enough to change), but it works in my developement environment.

What do I do with it now ?  I think it may fit in well as a front end to
Apache::Session, although it needs a name.  Its only around 400 lines
(including some POD and comments). 

It could fit in quite well with Apache::Session (ie providing a session
id, and Apache::Session does the server side storage).  It may also fit
in with other implementations such as Embperl, Apache::ASP, and Mason -
although most of these have their own implenetations.

My original plan - believe it or not - was to write a short "how to"
style tutorial to creating a mod perl shopping cart, the idea was not to
have another shopping cart, as there are many other better
implentations, but to have a few reasonably easy examples of mod_perl in
a real world type example.  This was inspired by someones post a few
months back for documentation / articles etc.  Well I started and wrote
a few modules, and went on to create a templating module (as per any
true path to mod_perl wisdom!), this session module and a DB abstraction
layer (and aparently I should be creating a caching module as well!).

Well any ideas - please let me know.

Greg Cope


A few details below.

AIM:

To manage session ID's between client and server - to get (or optionally
set) a sesion id via Cookies, Mungled URL or path_info.

Implemetation:

Uses a transhandler.
Optional configurations to alter logic / options via a package scalar eg
(some but not all) in a startup.pl:

use SessionManager();

$SessionManager::DIR_MATCH = '/foohandler'; # default is match
everything of /\.html/ !
$SessionManager::REDIRECT = 1;  # default to no
redirect
$SessionManager::DEBUG = 7; # default debug is off
$SessionManager::SESSION_ID_LENGTH = 32;# nice long ID lenght
$SessionManager::NON_MATCH = '\.gif|\.jpeg|\.jpg';  # ignore images

i.e. the above will session manager a URI matching 'foohandler', if
cookies are off it will redirect and set an mungled URI with a session
id length of 32 - it will also dump loads of debug info (between 3 and
20 lines a request), and ignore any gifs, jpegs, and jpg files within a
URI 'foohandler'.

Also:

$SessionManager::COOKIES_ONLY = 1;

Will only try cookies and then stop

$SessionManager::ARGS_ONLY = 1;

Will only try ARGS (after cookies).

$SessionManager::URI_FIRST = 1;

Try URI (mangled) after cookies, before ARGS, this allows changing the
order of which things are checked.

$SessionManager::USE_ENV = 1;

Instead of using pnotes entries use Environmental variables.

There are aslo a few other bits in the works for trying to setting a
cookie if they are off by redirecting, and then using a mangled URI or
ARGS if that failed - this will have a TTL, and DOMAIN vars that will
allow overriding of the defaults.

Thats about it.

Sounds interesting.

Is this module just managing the sessionID or also the session data?  i.e.
is the manager capable of storing complex objects (via something like
Storable or Data::Dumper)?  Will you provide hooks "caching and DB

storage of any data is upto you - can I suggest Apache::Session ?

$SIG{'DIE'}? IIRC, $SIG{'DIE'} has precedence over eval{}, something
many consider to be a bug.

If so, I'd try:
  eval {
local $SIG{'DIE'}; # undefine $SIG{'DIE'} in this block
...normal code...
  };
  if ($@) { ...normal code... }

Re: [Mason] Problem: no-Content.

2000-09-10 Thread Ian Kallen


HTML::Mason is your perlhandler in the /mason request space, so what's
supposed to handle a root object "/" request?  Do a simple setup for one
virtualhost and make sure your choices of documentroot, alias settings and
component_root settings agree before broadening the solution for multiple
virtualhosts.  Also, back down to Mason 0.87 until 0.89 is released.

  Hello all,
   
   -- The Problem -- 
   
   When i try try retrieve http://www.clickly.com/index.html 
   (Test-Site: not the real clickly.com) i get a blank return  and i 
   mean a real blank content return (tried it with telnet to port 80 and 
   the server only sends back the headers of the web-page?)
   
   Does anybody know what the problem is? I'va tried all sorts of 
   things but nothing worked.
   
   Thanks in advance,
   Guido Moonen
