regex quickie
I'm looking for a regex which will help me do this..
$string = 'google.com/?q=test';
$pattern_match = 'google|yahoo|msn';
What I would like to do is test if $string contains
one of the patterns in the pattern match and then
carry out a function based upon which pattern is
matched...
e.g.
if ($string =~ /$pattern_match/i)
{
my $matched_pattern = ($_?)
}
Any ideas?

Weird startup includes
I seem to have something weird going on. a Module I've written seems to be being included twice at server startup, but the second time its included the Apache::ServerStarting flag is set to 0... and is therefore causing all sorts of grief... (e.g. $dbh being forked).. Ive never noticed before that if you have you module declared twice (in httpd.conf and in startup.pl) that it would load the module twice I'm running apache 1.33 and mod perl... Any ideas? ###startup.pl use MY::Module; --- ## httpd.conf PerlModule MY::Module PerlHandler My::Module->handler . http://uk.answers.yahoo.com/

Zend PHP
I just had a demo of the Zend Platform and framework for php. It's got some really nice stuff, but ultimately the reason we may decide to ditch perl and move to php (h I know booo) will be down to support. OR lackthereof for Perl... So my question is, given I'm not a php fan, Is there an equivalent PERL based commercial entity who will provide support for a medium sized web outfit?

All, I had some code which ran the old version of Crypt::CBC (2.12). Using these headers to create the object:- my $cipher = new Crypt::CBC($ENCRYPTION_KEY,'Blowfish'); I've now built a new machine. Copied the database values (encrpypted using the above) onto the new machine DB using mysqldump etc.. However I've found a problem in that the new machine is built with Crypt::CBC version 2.17.. The above code does not work anymore as I now get the following error...:- Ciphertext does not begin with a valid header for 'salt' header mode at /usr/local/lib/perl/. I tried doing this:- my $cipher = new Crypt::CBC( -key => $ENCRYPTION_KEY, -cipher => 'Crypt::Blowfish', -insecure_legacy_decrypt =>1 -header =>'randomiv' -salt =>'1' ); But I still get the error...

Re: configuration error: couldn't check user. No user file?:
solved it... But there's a new mystery...
I was returning DECLINED in my Auth handler when the
following subroutine showed a user had disconnected...
sub client_still_connected
{
my $self = shift; #subclassed Apache::Request
my $conn = $self->connection;
my $is_connected = $conn->aborted ? 0 : 1;
if ($is_connected)
{
cluck ("connection still seems valid") if
$DEBUG;
my $fileno = $conn->fileno;
if (defined $fileno)
{
cluck ("Still seems valid\n") if $DEBUG;
my $s = IO::Select->new($fileno);
#$is_connected = $s->can_read(0) ? 0 : 1;
}
}
cluck ("is_connected=$is_connected\n") if $DEBUG;
return $is_connected;
}
The problem I have now, is this subroutine always
fails at the $s->can_read line whene a user POST's a
large amount of content...
And intermittently on other page requests (GET & POST)
the subroutine fails the can_read but the client is
Still there
Any ideas?

You wouldn't believe the problems I've had with AccessHandlers... Although saying that I was trying to do a set_handlers for the contentphase... which was being completely ignored by apache... I'll have a think about it... But the idea is to make the authentication be completely invisible to the users page request.. so if their login times out, and they've just submitted a post to a message board, we want to preserve their post throughout the authentication and then when they're authenticated, have the post occur and the user never have the authentication process appear in their browser history...

Authentication
All, During the Authentication phase, Any custom responses that need to be sent back to a user, MUST be sent with FORBIDDEN using custom_repsonse? Under Authentication 200 (OK) simply lets Apache Move on the to the next phase (authz, content etc..)... I have an authen handler which uses cookies.. and only accepts username and password submits under https... I'm getting grief from our sysadmin that there's too many 403's being served... 1) to redirect the user from their http request to a https page.. 2) custom response showing the login page 3) redirect user to original http page so 3 403's when a user has no valid cookie Is this abnormal?

Re: is_intial_req
Hey Frank..
I agree, thats why I setup the logout2 control test.
What I don't understand is "why" it is tripping it
out. Surely it would only trip it out if the order of
the httpd.conf filesmatch and location is set one way
around, and then not trip it out if the order is
reversed, not both as I'm seeing...
Would this also mean that once my ContentHandler has
returned OK, and sent Data back to the user and
"finished" as far as I'm concerned, that the Apache
server is then going off and running the old logout
embperl scripts too?
If so, how do I tell apache that I don't wish any more
contentHandlers to be run?
I posted an issue a while back about trying to use
push_handlers and set_handlers... and push_handlers
works, but set_handlers doesn't... never got a
solution, beyond what I'd already tried.. All very
weird.

is_intial_req
I'm a little confused. And was wondering if I could
get a sanity check..
I have a mod perl method handler and at start it runs
this code
my $is_initial_req = $r->is_initial_req;
my $is_main = $r->is_main;
my $main = $r->main;
my $proxyreq = $r->proxyreq;
print STDERR
Dumper('is_initial_req',$is_initial_req,'is_main',$is_main,'main',$main,'proxyreq',$proxyreq)
if $DEBUG;
I am running a system which has embperl installed
using this:-
SetHandler perl-script
PerlHandler Embperl
Options ExecCGI FollowSymLinks
And My handler is called using this
setHandler perl-script
PerlModule My::Apache::Authen::Cookie
PerlHandler My::Apache::Authen::Cookie->logout
I also have a second 'control' instance of this
handler installed purely for this debugging
setHandler perl-script
PerlModule My::Apache::Authen::Cookie
PerlHandler My::Apache::Authen::Cookie->logout
Finally there is a directory under my document root
called /logout/ which contains old Embperl scripts I'm
superceding with my handler (so would be found on a
FilesMatch).
The question I have is this.:-
When I visit /logout I get the following Dumped
information from my handler:-
$VAR1 = 'is_initial_req';
$VAR2 = '0';
$VAR3 = 'is_main';
$VAR4 = 1;
$VAR5 = 'main';
$VAR6 = undef;
$VAR7 = 'proxyreq';
$VAR8 = '0';
But when I visit /logout2 I get the following:-
$VAR1 = 'is_initial_req';
$VAR2 = 1;
$VAR3 = 'is_main';
$VAR4 = 1;
$VAR5 = 'main';
$VAR6 = undef;
$VAR7 = 'proxyreq';
$VAR8 = '0';
Why is is_initial_req consistently 0 for logout and
consistently 1 for logout2...
I tried swapping the order of the FilesMatch and the
Location configs in my httpd.conf but this made no
difference...
So can anybody clear up this mystery for me?
Kind regards
Marty

Re: Multiple Handlers
It doesn't seem to work... This was the original
solution I tried..
Here is the code:-
if (Apache->can('set_handlers'))
{
print STDERR "CAN PUSH HANDLERS OK\n";
}
else
{
print STDERR "CANNOT PUSH HANDLERS OK\n";
}
my $list = $r->get_handlers( 'PerlHandler' );
print STDERR "\n";
print STDERR Dumper($$,$0,$list);
print STDERR "===\n";
$r->set_handlers( 'PerlHandler' =>
['My::Apache::User::Notification']);
$r->handler('perl-script');
my $list2 = Apache->get_handlers( 'PerlHandler' );
print STDERR Dumper($$,$list,$list2);
print STDERR "==\n";
Here is the output I get in my logs:-
CAN PUSH HANDLERS OK
==
$VAR1 = 15253;
$VAR2 = '/www/common/conf/core/traps.conf';
$VAR3 = [
'Embperl::handler'
];
==
$VAR1 = 15253;
$VAR2 = [
'Embperl::handler'
];
$VAR3 = [
'III::Apache::User::Notification'
];
==
==
15253 Apache::AuthenDBI request type = main
In Embperl::handler
So as you can see, the set_handlers seems to work...
But after the Authen stage has returned OK, the next
handler to take control is Embperl::handler...
Any Ideas?

Multiple Handlers
All, I'm trying to make something work in mod perl, and all the docs seem to be pointing me in ways which just don't work on our system... Server version: Apache/1.3.33 (Unix) SunOS 5.9 perl, v5.8.6 I wish to have a handler which sits after the Authentication stage, which can choose whether to display a HTML page instead of the originally requested page.. The originally requested page will usually be served via Embperl, or a method handler.. I originally tried using $r->set_handlers. in my PerlAuthenHandler. But this made absolutely no difference to the current request... e.g. if did a get_handlers call before and after using set_handlers, it clearly showed me the handlers I'd set using set_handlers, but apache ignored this and carried on serving it's original get_handlers() anyway.. I found many different people reporting bugs in the set_handlers mechanism and push_handler (which worked but couldn't help me as what I wanted to do was unshift (not push) the handlers). So I tried defining two handlers for the same request, the first one my custom handler, the second one Embperl as normal. Now when my custom handler returns DECLINE the page requested displays normally.GREAT:-)... But when my custom handler actually serves a page, and returns OK, I actually see the custom handler page being served, and then the original requested page appears below with a load of headers and server error messages So basically BOTH handlers are being called Now, I was under the impression (but could be wrong) that if 2 content PerlHandlers are defined for a request, then if the first one returns OK then the second handler doesn't get called, but if it returns DECLINED then the second one gets called... Can anybody throw some light on this? Why doesn't set_handlers (used in the PerlAuthenHandler phase) allow me to define the PerlHandler for the content phase? How do I prevent other handlers (independant of my custom handler) from being run if my Custom handler decides to serve a page... Kind regards Marty ___ Yahoo!

to ENV or not to ENV
All,
We're in the process of introducing mod perl method
handlers and template toolkit into a system which is
also running Embperl. There is some interaction
between the two, and as Embperl (and especially our
code which uses it) uses %ENV to pass around variables
like $ENV{REMOTE_USER_ID} and other useful things I
wanted to get some views on the use of %ENV in this
form.
I was under the impression that using %ENV is a bad
thing to do.. mod perl provides PerlSetVar to set
variables for mod_perl within conf files... But when a
variable isn't set in a conf file, but in an embperl
script, the way I see it there are several ways to
transfer data between the two systems.
1) using %ENV
2) setting using our own subclass of Apache::Request's
pnotes or notes methods
3) Passed as parameters between them all
4) stored and retrieved through a session store
5) stored in cookies
I think that the whole thing comes down to the first
2... the last few are too impractical (given an
already existing code set) as a generic method...
I believe that using %ENV opens up the system to bad
coding problems, e.g. writing a backend module for DB
interaction and then slipping in a call to %ENV for
some front end user information. I also believe there
has been some discussion on this list a while ago,
which came out in favour of not using %ENV at all if
it can be helped But I can't remember why this was
a bad thing...?
I favour using Apache::Request's pnotes, notes and
dir_config methods for acheiving all of this using
methods as wrappers to the information required
So can anybody shed some light on this pros/cons
discussion?
Kind regards

slightly OT - defining variables in httpd.conf for use in httpd.conf
All,
I know I've seen this done before, but I'd like to
define a variable at the top of my httpd.conf file,
and then use it many times throughout the conf file...
e.g.
define Server='fred'
DocumentRoot /usr/local/${server}
I just can't find any info on this... Can anybopdy
point me at the right place..
All I find in google is how to use PerlSetVar, which
isn't what I'm trying to do...

I haven't used Memchache yet, but it has nothing to do
with databases
It CAN be used to prevent database load, OR it could
be used to prevent too much access to flocking
files...
Consider the Example at the top of that link
sub get_foo_object {
my $foo_id = int(shift);
my $obj = $::MemCache->get("foo:$foo_id");
return $obj if $obj;
$obj = $::db->selectrow_hashref("SELECT FROM
foo f, bar b ".
"WHERE ... AND
f.fooid=$foo_id");
$::MemCache->set("foo:$foo_id", $obj);
return $obj;
}
your subroutine would be
sub get_foo_object {
my $foo_id = int(shift);
my $obj = $::MemCache->get("foo:$foo_id");
return $obj if $obj;
#
#get $obj from your flocked file mechanism that you
are already using...
##
$obj=get_from flockfiles($foo_id)
$::MemCache->set("foo:$foo_id", $obj);
return $obj;
}
It depends on how you've implemented the existing
mechanism I guess The above seems expect
instantiated Objects...
Personally I'm curious as to why you don't want to use
a database

Hi Ben, I have a few thoughts on this... In my experience writing a daemon process is easy (well ish) but then configuring your system to manage them (have they died, have they crashed etc..) is more trouble than its worth. Is it possible to use some kind of cronjob based system, which runs a script every minute, picks up a list of things to process from say a database (which your Handler writes to, to communicate to the backend processes)... Of course a lockfile mechanism would need to be used to ensure only one cronjob script runs at any one time...

Re: Overriding PerlAuthenHandler in sub-directories
I was looking into this a while back, and came across several posts that described using a PerlAccessHandler to determine if PerlAuthenHandler should be set or not. You could then setup PerlSetVar Require_Auth '0' in any sublocations that didn't need Auth. your AccessHandler would then do a set-handlers call and get it to return OK for an AuthHandler (I've tried to dig out the syntax but I can't find it).. I tried it briefly and couldn't get it to work at all, but I got the impression that this was down to the really quirky setup I was trying to do it on.

Re: sessions:THANK YOU!
I didn't get chance to reply, and the others covered everything, but the point of Apache::Session is that you don't need to store ANY data other than a session_id in a hidden field or in a cookie... All of the rest of the data you need gets stored locally on the server side. Much more secure.

Re: HTML::Embperl + mod_perl + segfault
I upgraded to the latest version of Embedperl and ran
the same code from my previous post. IT no longer
segfaults but I get the following error...
Embperl::Execute({
req_rec=>$r,
inputfile=>$file,
param =>[$params],
output => \$html
});
and I get the following error:-
Error in Perl code: Can't call method "headers_in" on
an undefined value at
Which is $req_rec.
It's undef.
I tried this without the req_rec=>$r too and it made
no difference.
Any ideas? Is it related to

Re: ... and startup.pl equivalent?
Hi Colin, just my opinion, but from a 'practicalities' point of view, as startup.pl gets more complex (your site grows larger, you wish to do more intricate mod_perly things), you will find that it is a distinct advantage to run it from the command line in the debugger. you wouldn't be able to do this if you buried all your perl in the apache configs... I'm sure there's many more reasons to keep your startup script outside of the http configs, usually it's because it's only neat and tidy to begin with embedding your perl into your configs, but as your site configs get larger, you'll probably start thinking it a better idea to put all your sections in their own seperate httpd conf file, which might as well be a startup.perl script..

HTML::Embperl + mod_perl + segfault
All, I'm getting segfaults on every page request I make to a mod_perl handler thats running under HTML::Embedperl. We're trying to migrate away from Embperl as fast as possible, but whenever I call HTML::Embperl::Execute in my code more than 4 or 5 times I get seg faults.. perl 5.6, apache 1.3.33... I realise that this is one of those 'needle in a haystack emails' but I was wondering if anybody has any experience running HTML::Embperl who may have seen this sort of thing before.. I know that the code I'm using doesn't segfault when I ran it on a different machine - one I'd built myself and it was running under perl 5.8.5. [Mon Dec 13 18:25:16 2004] [notice] child pid 24141 exit signal Segmentation Fault (11) We can't upgrade to perl 5.8 as some of the legacy code we have just breaks - (think code written 5 years ago, without the concept of use strict). I've tried looking at the embedperl scripts that are being called, and no matter which ones I comment out,(remove possibility that it's some component within the embperl thats causing it) it's always the 5th or 6th script being run that causes the segfault..

Authentication using https
All, I'm about to replace the authentication mechanism that our web site uses. However I wanted to sanity check my thought process. Is it possible to have an Authen handler sitting on certain areas of a site, and if a user isn't logged in (i.e. doesn't have an auth session cookie) we present them with a form. (I can do this, but the next bit is new to me). Then when they send their details, i.e. username and password, they go over an SSL connection, which provided they are correct, then shows the page the user originally wanted? Basically I have a mechanism working that does this without the SSL, but can I update it to use an SSL connection for the login form submit? Marty ___ ALL-NEW Yahoo!

Re: Protecting against Cookie copying
Thanks everyone. You've done a good job of assuring me that I haven't missed the whole point of the way these things work. There's been some really useful ideas, suggested and I'm going to have a think about which, if any, are worth implementing. Ultimitely I'm upgrading our site from normal Basic authentication, which sends username and password unencrypted anyway, so compared to that the security upgrade is still a big increase!

Protecting against Cookie copying
All, I'm looking into ways of uniquely identifying a computer. I've been reading around the web looking at different mechanisms, and so far I've drawn a fuzzy blank. Currently, I want to use SSL to let a user sign in and then I return a session cookie, which I then use to confirm the user is logged in when they come to non-ssl pages. What I wish to do is prevent another user copying the session cookie, from one computer to another, and then gaining access. Originally I wondered if I could get at the mac address of the connection, but that seems to be a dead end. After a little further reading It seems that there is a UUID generated at the handshake? stage of SSL, so therefore I wonder if I can use this, e.g. map my session_id to a UUID, and then when I check the session is valid I crosscheck this, however I'm not sure if I can get the UUID over a non-SSL connection. I'm sure I'm not the first person to want to uniquely identify a computer that comes to my site, without blindly trusting cookies, but I'm at a loss of how to find anything better than ipaddress to session cookie mapping. (which is kinda pointless for Natted addresses I know). Does anybody have any ideas, pointers...? Regards Marty ___ALL-NEW Yahoo!

Re: Request methods not found
Hi Marina,
Can you post a bit of your http.conf which declares
your AuthHandler's usage?
Are you saying:-
PerlAuthHandler Our::Auth->authen_handler
or
PerlAuthHandler Our::Authen::authenhandler
I ran some code across SuSe and Redhat and noticed
different behviours for using "->".
If you use "->" I think that this is interpreted as a
'method handler' and as such the first argument to
your authen_handler subroutine would be your classname
(Our::Auth) and the second argument would be the $r
(Apache->request).
Can you add this to your code:-
> package Our::Auth;
> use strict;
> use Apache;
> use Apache::Constants qw(:common);
>
use Data::Dumper;
> use mod_perl ();
>
> sub authen_handler {
>
print STDERR Dumper(@_); #lets see what you
got passed
> my $r = shift;
>
> my ($res, $sent_pw) = $r->get_basic_auth_pw;
>
> return $res if $res != OK;
>
> my $user = $r->connection->user;
> if (!$user || !$sent_pw) {
> return AUTH_REQUIRED;
> }
> return OK;
> }
> 1;
I suspect that you will see 2 variables passed into
you subroutine
1 = 'Our::Auth'
2 = instantiated Apache object
However I did have a skinful last night and my brain
is a little sluggish, so I could be wrong...(anybody
feel free to correct me)

Re: Apache::DBI, Postgresql, and transactions
Heyho,
I spent ages trying to track down a mysql/Apache::DBI
bug, and whilst I'm not sure what's going wrong with
your system, I found it useful to add the PID of the
individual mysql process (not sure if you can do this
with postgresql) to the $dbh and then implement a
error handler which logs the pid. Then (again not sure
if you can do this in postgres) trace that pid to a DB
log file. in mysql you can get the last run command of
that PID, and then see if something is amiss on the DB
end...
Anyway here's a quick brain dump, you'll probably have
to tailor this to your needs..
Regards
Marty
something like this:-
my $dbh;
my %attrs=();
$attrs{RaiseError}=1;
if ($DBI::VERSION >= 1.21)
{
#cos old DBI doesn't support this and we had
many versions running
#cluck ("Adding ErrorHandler as DBI (version
$DBI::VERSION) Supports this method\n");
$attrs{HandleError}=\&DBIErrorHandler;
}
else
{
#cluck ("Not Adding ErrorHandler Support as DBI
version ($DBI::VERSION) Does not support this
method\n")
;
}
eval
{
$dbh = DBI->connect(
$dsn,
$db_user,
$db_password,
\%attrs
);
}; #because our bug was in the connect, you may
not need this
my $c_id;
eval
{
my $stm_id = qq{SELECT connection_id()};
($c_id) = $dbh->selectrow_array($stm_id);
};
if ($@)
{
#Probably older version of mysql, ignore
$c_id='UNKNOWN - PROBABLY AN OLD DB Server';
}
$dbh->{private_MY_HASH}->{connection_id}=$c_id;
sub DBIErrorHandler
{
my $sql = shift;
my $sth = shift;
my $value = shift;
my $dbh;
my $ref=ref($sth);
print STDERR "In DBIErrorHandler\n";
print STDERR "Incoming handle is '$ref'\n";
print STDERR Dumper(@_)."\n";
if ($ref =~ /DBI::st$/)
{
#print STDERR "IS a STH\n";
$dbh=$sth->{Database};
}
elsif($ref =~ /DBI::db$/)
{
#print STDERR "IS a DBH\n";
$dbh=$sth;
}
else
{
print STDERR "Unable to Determine db/sth from ".
Dumper($sth);
$dbh=$sth;
}
if (ref($dbh) eq 'HASH')
{
print STDERR "\nConnection ID is

}
else
{
print STDERR '\nConnection ID cannot be
established, $dbh is not a hashref';
}
return 0; #Return false so RaiseError is now
executed

Mod perl performance and DSO?
All, I have a brand new redhat 9 box. I have plenty of diskspace and I need to install apache mode perl mod php and mod ssl. Most information I find on the web to do this uses DSO. Performance is absolutely critical for this machine, it's going to be handling millions of web 'hits' per day. My question is, should we use DSO or not?

I was always under the impression that in order to use a module you should declare it with PerlModule My::Module set-handler PerlScript PerlHandler My::Module #in whatever permutation My question is, If you don't have a PerlModule statement or a use My::Module, or a require or a +My::Module statement so it looks like this #PerlModule My:Module set-handler PerlScript PerlHandler My::Module But the module My::Module is on the Include path for apache (hmm or is that the apache user), What exactly happens? or should happen?

Method Handler not working
All,
I have a quirky issue concerning a redhat machine and Apache 1.
I have a method handler
sub handler ($$)
{
my $class=shift;
my $r = shift;
}
Which when running on a redhat linux machine dies with the error message "Attempt to bless into a reference" and when analysing the incoming variuables, $class is really $r. So apache seems to be ignoring the method handler directive.
This error doesn't occur on machines running the same code (mirrored in the same way as the redhat box), it works perfectly fine.
Has anybody seen this type of error before, is it the symptom of some other issue that I've missed somehow?
Regards
Marty

Re: DBI and Apache::DBI
You didn't specify which Database server you're using. If it's mysql you need to be cautious of the 'ping' method used by Apache::DBI to check if a connection is stale or not. the DBD::mysql ping method always returns a 'true' string e.g. "0 but true" rather than a 1 or a 0. I believe the latest version of DBD::mysql has an automatic 'reconnect' feature, but We're still seeing failed connections occuring infrequently on our systems. (Still investigating).

Refreshing Caches at server restart
All,
I have a few modules which cache a few arrays. I want to get around the problem of these arrays staying cached when Apache Restarts gracefully. I can't have the server stop and start, and Apache::Reload isn't really the solution for this problem (or at least I don't think it is).
Has anybody done something which can allow me to force certain modules to reload/refresh whenever Apache does a Graceful restart?
