Re: mod_perl v2 Forking
Cameron, Have you tried issuing the command to `at`? If you don't need to interact wih the report generator, and can pass all the parameters in the command line or via a tmp file, this is a great solution. at (and the corresponding atd) will preserve your environment vars and other niceties. regards, martin

Is there any other way to figure what's wrong? The code isn't mine, but
someone else's, so I'm really not a whole lot of use there. As for
posting an example, it's the same as from
http://sourceforge.net/project/showfiles.php?group_id=12829 but just
modified slightly according to the porting guidelines. I've only changed
and added a few use statements and changed the constants from the m_p 1
form to the m_p 2 from. I've attached the two pieces of code that I
modified (the module and the handler) for you.

Output of mp2bug it *attached* to this message (if it includes it inline again I'll email the developers). Nevertheless I did try the attached files and I can't reproduce this problem with the latest cvs. Try upgrading your mod_perl to the latest cvs version, I have no idea which version you have. I'll use that ASAP. One thing that for sure is wrong with that code is that you either use 'Apache::compat' and you don't replace Apache::Constants with Apache::Const, or you don't use 'Apache::compat' and then in addition to what you have added (i.e. use Apache::Const -compile = qw(:common);), you need to s/Apache::Constants/Apache::Const/g in the code.

Your particular problem report was fine, what you have missed is the output

here
http://marc.theaimsgroup.com/?l=apache-modperlm=105968263417468w=2
Sorry, my deb package dont have the t/ stuff.

In any case, have you tried using the snooping filter I was talking about
in my previous reply? It shows you exactly what's going on inside.
It confirms my problems. Here is output:
connection output filter
o bucket 1: FLUSH []
connection output filter
o bucket 1: FLUSH []
connection output filter
o bucket 1: FLUSH []
connection output filter
o bucket 1: TRANSIENT
[htmlhead TITLE /headbody BODY/html]
And here is the code that generates this:
sub handler {
my $r = shift;
$r-content_type('text/html');
$r-print (htmlhead TITLE /head);
$r-rflush();
$r-print (bo);
$r-rflush();
$r-print (dy BODY);
$r-rflush();
$r-print (/html);
return Apache::OK;
}
1;
For the record, I am able to cut up a stream nicely using mod_cutup
[1]. This results in something like:
connection output filter
o bucket 1: TRANSIENT
[htmlfoo]
o bucket 2: TRANSIENT
[headbody]
o bucket 3: TRANSIENT
[
!-- sd]
o bucket 4: TRANSIENT
[sd --
[...]
Which at least proves that the snoop filter is working as expected :-)
Anyway, I'll try with the latest mod_perl version as soon as time
allows and post my results later.

I've seen this also, but was never able to isolate a cause. rflush() works fine, it's possible that the issue with the streaming filter or some other upstream filter that ignores the flush buckets. I doubt that, no other external filter is in use. Are you using the latest mod_perl 2.0? Nope. I am using 1.99_07. (Btw, that information _was_ included in my report, but you trimmed it away:) This is with: Apache/2.0.47 (Debian GNU/Linux) mod_perl/1.99_07-dev Perl/v5.8.0 It's much appreciated when bug reports are written using the following guidelines: http://perl.apache.org/docs/2.0/user/help/help.html#Reporting_Problems Pardon me, but I do believe I supplied enough and accurate information -- including relevant, trimmed code snippets and excerpts from apache logs in my report. Except from the fact that I did not build mod_perl myself, I can't really see what I missed to include? Martin, please check the mod_perl 2.0 test suite, it has plenty of examples where it used exactly for the reason you've described. Ok, thanks I'll check it out. I'm guessing that my mod_perl is too old, I like to stay with the prebuilt packages (debian) if possible. But if needed, I'll build the latest version and test it. Just thought that someone would know, thats all.

Re: How to restart the root server from within modperl?
how can I restart the root httpd server from within modperl? Use `at` to schedule it a minute in the future -- effectively forking it. Note that normally apache starts as root and runs as an unprivileged user. If this is the case you _can_ achieve it using a suid wrapper or sudo, but you'll risk opening a very serious security hole in the system. So don't. Instead, run apache as a regular user, on a high port. If you absolutely need to be in port 80, either setup a simple lightweight apache on port 80 as a reverse proxy (see the mod_perl guide) or, even simpler, do some port forwarding from port 80 to your high port of choice. regards, martin

I supposed the browser to resend always an unique bowser session
id, which is used by apache to save certain values, like
$ENV{'REMOTE_USER'} (similiar to a session-cookie with uid and
serverbased $vars) .. Isn't this the way Basic Authentication
scheme works ? ..
Nope. When the browser gets a 401 response from the server, it will
(most likely) pop up a dialog asking the user for name and

Sorry, I was not clear enough. The problem is that I need to run mp2-handlers before _and_ after the actual mod_auth (compiled apache binary) module. But apparently mp2 runs _all_ its Authen-handlers at the same time, ie it is not possible to split handling in the same phase between mp2 and apache -- something that I must do (afaik?) because of the ledger-counting. By keeping count like this (and assuming it works in a real situation), one can device lots of cool ways to add login and password policies. Just change relevant part in the Bouncer/Ledger. I'll take a closer look at this in a few weeks when I'm back full time, but right now I think I would have coded it all in the PerlAuthenHandler - I think that basic housekeeping like last-auth, etc all are ok things to put into that phase, so it makes a certain amount of sense to add your denial rules to that phase as well. Ok. But when I tested it in practice it failed because I need perl-Authen-code to run just before, and just after mod_auth has finished. The only way I could figure out how to do that was to put Bouncer in the Access phase and Ledger in the FixUp phase. On other words abusing the phases somewhat.

Combining authen-handler with mod_auth
Hello The short version: How can I force my mod_perl Authen-handler to run after mod_auth and not before it? The long version: I have been trying to do some clever things using a combination of mod_auth with Authen-handlers in mod_perl2 (v1.99.07-1) and apache 2. The actual implementation is not really important, but for reference see [1]. The handler should count the number of failed retries for each user and then do take appropriate action (for instance, ban the user or log info to a file). My approach is to have a perl-handler run right *after* mod_auth when mod_auth has decided the supplied uid/password did not match [2] I have no problems creating a plain authentication handler in mod_perl, but after trying and trying lots of combinations with perl-handlers I am struggling to get my handler to run *after* mod_auth. Like this: Location /secure/ # AuthAuthoritative Off AuthUserFile /tmp/htpasswd AuthType Basic AuthName Secrets Require valid-user PerlAuthenHandler MyApache::AuthenTest /Location No matter how I configure AuthenTest, it will always run right before mod_auth! Any ideas how do do this, or for that matter, if there is another approach that is better. /Regards Martin [2] http://groups.google.com/groups?hl=enlr=ie=UTF-8selm=be0i9b%2411n3fm%241%40ID-156202.news.dfncis.de [1] I realize there may be issues with HTTP_UNAUTHORIZED causing apache to abort the chain (according to docs anyway), but that can be handled by patching auth_mod if needed.

Can't call method is_initial_req without a package or object reference at .........
All,
I'm having some problems with Apache giving me grief, or most probably me
getting my knickers in a complete twist.
I get the following error:-
Can't call method is_initial_req without a package or object reference at
.
It seems to happen when my URL ends like this:-
/somepath/16
but not when it ends like this:-
/somepath/16/
Below is the code which is where the error occurs.
sub handler {
my $r = My::Apache::Request-instance(shift);
print STDERR Dumper($r);
print STDERR \n\n\nBOOOBS\n\n\n\n\n;
die $r not defined unless $r;
return OK unless $r-is_initial_req();#ERROR OCCURS HERE
my $uri = $r-uri;
my $log = $r-log;
..
}
The handler is simply a multiplexer which based upon a database
configuration adds the relevant method handler to the handlers queue.
The 'instance' routine for My::Apache::Request is inheritted from the
Apache::Request class.
the 'new' routine for My::Apache::Request is as follows:-
sub new
{
my ($class, $r) = @_;
my $length=32;
unless ($r-is_main )
{
print STDERR Apache::Request is not Main, Getting Main\n;
print STDERR Dumper($r);
$r=$r-main;
print STDERR Main Apache::Request is:-\n;
print STDERR Dumper($r);
print STDERR DECLINING\n;
return DECLINED;
}
unless ($r)
{
print STDERR making a new Request object\n;
$r = Apache-request;
}
$r=Apache::Request-new($r);
my $self = bless {_r = $r}, $class;
my $t=substr(Digest::MD5::md5_hex(Digest::MD5::md5_hex(time(). {}. rand().
$$)), 0, $length);
$self-{XX_created_time_XX}=$t;
my @params=$self-param();
print STDERR Here's the Parameters for $class\n;
print STDERR Dumper(@params);
my $lang_id=$self-param('lang_id');
if ($lang_id)
{
$lh=My::Maketext-get_handle($class,$lang_id);
}
else
{
$lh=My::Maketext-get_handle($class,My::Conf::DEFAULT_LANGUAGE_ID);
}
print STDERR Creating .ref($self). $t\n;
#$self-interpret_uri;
return $self;
}
Re: Can't call method is_initial_req without a package or object reference at .........
Ok, that makes sense, thank you:-)
But 'What' should I return, is $r-main the right thing to return?
unless ($r-is_main )
{
print STDERR Apache::Request is not Main, Getting Main\n;
print STDERR Dumper($r);
$r=$r-main;
print STDERR Main Apache::Request is:-\n;
print STDERR Dumper($r);
print STDERR DECLINING\n;
return DECLINED;
}
you're not returning an object from your constructor on internal redirects

I've found that it's pretty rare that you want to mess with main vs
subrequest logic
yourself. instead, I would just make the constructor return an object
based on whatever
mod_perl passes it which is, in turn, whatever request record Apache deems
to be the
proper one for the current (sub)request.
so new() should probably just be something like
sub new {
my ($class, $r) = @_;
$r = Apache::Request-new($r);
my $self = bless {_r = $r}, $class;
$self-init();
return $self;
}
if it is important to insure that you only populate object attributes
once, even in the
case of internal redirects or lookups, you could hang attributes off of
pnotes in the main
request
sub init {
my $self = shift;
$t = ubstr(Digest::MD5...);
if ($r-main) {
$self-{XX_created_time_XX} = $t;
$self-{_r}-pnotes(XX_created_time_XX = $t)
}
else {
$t = $self-{_r}-main-pnotes('XX_created_time_XX');
}
...
}
or somesuch. untested, but you get the idea :)

font width to pixel width in perl - but also offtopic in javascript
Hi All, I'm sure this can't be an issue that hasn't been tackled, but I couldn't find anything in the archives so:- I'm trying to find a way in which I can calculate the pixel width of a string in a given font. I'm doing this to feed a javascript file, so I am also looking at doing this in javascript also. currently all I can find is the php 'imagefontwidth' function. Does anybody know of an equivalent in perl? I remember having issues like this in TK, but not sure the solution there would be appropriate. I guess this is fuzzily on topic, but if anybody has any off topic experience I'd be greatful. any approx solutions which can 'guarentee' a 'larger than the minimum space required' would also suffice, e.g. is there an approximation which I can use based upon the maximum character width possible for a font etc... Regards Marty

Re: how to secure perl modules?
Hi All,
Just to throw a spanner in the works, a little while ago I came across the
following Article on the Net.
http://www.perl.com/pub/a/2002/10/15/radiator.html
From what I can tell The author of the 'radiator' product claims to have
successfully shipped 'encrypted' code.
I've been pondering how to do this for ages anyay, I realise it's not
completely foolproof, but I'm trying to find a mechanism that would stop
anybody but a perl litterate hacker from getting at my code.

Subclassed Apache::Request Objects and their creation/destruction
All,I'm
looking for some help with understanding how the Apache::Request objectsare
created and destroyed.I have the following params set in my
httpd.confKeepAlive OffPerlChildInitHandler
Bficient::Apache::DBloadWhich as I understand it should mean that an
apache::Request object iscreated for each request, and is destroyed at the
end of a request.So if I add 'CREATION and DESTROY' warnings to my
Apache::Request code tolog when a request is being created and destroyed I
should see the objectsbeing created and destroyed as they are
used.This would lead me to believe that when I stop apache, the only
DESTROYmessages I should see are those belonging to the childInitHandler,
e.g. Ishould see my database handles being destroyed.I'm just trying
to get an understanding of what 'should' happen, so that Ican work out If I
have a problem with my code.I have subclassed Apache::Request and I'm
seeing my subclassedApache::Request objects being'DESTROYED' under an
apache stop. AS WELL as after the Request completes,e.g.after the
request completes I see this:-$VAR1 = bless(
{
'r' = bless( do{\(my $o = 145326836)}, 'Apache::Request'
)
}, 'Bficient::Apache::Request' );DESTROYING
Bficient::Apache::RequestBut when I stop apache I see
this:-$VAR1 = bless(
{
'r' =
undef
}, 'Bficient::Apache::Request' );DESTROYING
Bficient::Apache::RequestThis doesn't look 'right', but I'm not
sure.Attached is my Bficient::Apache::Request object, If that
helps.Any help, or pointers would be greatly appreciated,kind

Apache::AuthTicket lookalike for DBM files
I am looking for a mod_perl implementation of mod_auth_dbm that takes cookies instead of HTTP-AUTH Basic. Or perl implementation of mod_auth_cookie, perhaps (I think mod_auth_cookie does exactly that). I was sure I would find it in CPAN, and, sure enough, AuthTicket and others are there, offering far more than I was expecting... But I could not find one that deals with NDBM files. A search for Apache::Auth* is not returning likely candidates. Unless there is a DBI/DBD driver that would allow using NDBM files with AuthTicket? There doesn't seem to be any :( I am tempted to add NDBM support to AuthTicket but I am 99.9% certain that there _has_ to be a module providing the functionality I am thinking of. Just to clarify, I don't need the 'ticket' mechanism, just cookie-based auth against DBM files, with the same options that mod_auth_dbm offers. Oh, and lazyness is one of my virtues ;) cheers, martin --

Quoting Martin Moss [EMAIL PROTECTED]:
All,
Can Anybody see what I'm doing wrong here?
I have the following error :-
[error] Insecure dependency in unlink while running with -T switch at
/usr/lib/perl5/site_perl/5.6.0/Apache/Session/Store/File.pm line 106.
The problem is not with your code, it is that Apache::Session::File
does
not work in Taint mode. Apache::Session::Store::File gets the session ID
from a
file (which means session_is is tainted), and then uses the tainted
session_id
to delete a file (hence the unlink error).
A quick fix for this is for you to untaint the session ID yourself
after
the session has been unserialized. Put the following two lines right after
you
tie the session:
$session{_session_id} =~ /^([a-zA-Z0-9]+)$/;
$session{_session_id} = $1;
This probably should be fixed in Apache::Session itself as I am sure
other
people will run into it.
By the way, you really shouldn't be using Apache::Session::File
anyway for
performance reasons. At least use Apache::Session::DB_File which most
likely
doesn't suffer from this taint problem and will be much quicker.

heheheh, I can't use Apache::DBI. I have multiple database connections.which are authenticated for different users. Am wondering whether to bother with the persistance at all, I can retrieve all the data I need out of the database anyway, I just wanted to reduce the database lookups. Especially as I could be operating on 100's of records. I was using Apache::Session to generate session IDs and allow me to timeout users etc...

Browser doesn't stop loading a page
All, Not much to go on I know, but has anybody ever had this problem? When I load one of my webpages the browser never stops loading, e.g. the page loads ok and I can see and interact with it, but the ie spinning globe still keeps spinning and the status bar at the bottom of the page still shows the page is loading something.. The process does seem to run and exit normally in my logs. I'm at a loss as to what is causing it. This only happens on one specific page on my server. Any ideas would be appreciated. Regards Marty
Re: Browser doesn't stop loading a page
Yes I think you're right, When I click on a link that takes me to the page in question the page simply stays loading, but it Iclick into the URL Address bar and press enter to reload the page the page loads fine without continuing to spin the globe. I've tried making the changes you suggested below, but I think I'm missing something else as the problem still occurs.

Re: mysql password encryption
Cheers for all your help,
I realised that I didn't need to worry about decrypting the passwords as I

Are the databases under the same database engine instance? If they are
its
not a problem as the password is the system table users and you can grant
access for that user to various databases in the system table database.
To
use the encrypted password field, use the password('password') function
supplied by the MySQL library. It only encrypts your password string, but
it will let you do a compare of the strings.
Hope this helps.

Quoting Martin Moss [EMAIL PROTECTED]:
All,
I wish to let a user use the same password for them to authenticate to a
multitude of mysql Databases AND to authenticate themselves on my
modperl
site.
the problem I have is that I store the password in the database as a
Password field. However when I wish to use DBI to connect to another
mysql
database I cannot use the Password stored in the database as it comes
out
encrypted. I really don't want to store the unencrypted password
anywhere
on the system. Is there a way to let DBI/mysql know that the password I
am
giving them is ALREADY encrypted?
A feature like that would defeat the purpose of encrypting the password in
the
first place. The point of encrypting the password is so that if someone
gets
their hands on the password list, they can not use the encrypted password
to
access the system. They would have to crack the passwords first before
using
them to access the system.
By allowing someone to access the system with an already encrypted
password,
then your passwords might as well not be encrypted at all.
Since you are using MySQL, have you looked at using the
mysql_read_default_file
option to store your password in a config file? Using a DSN like the
following
allows you to keep the username and password in a config file. Check the
DBD::mysql perldocs for more info, and the MySQL docs for all the
parameters
you
can put in such a file.
DBI:mysql:test;mysql_read_default_file=/etc/mysql/test.my.conf
and in /etc/mysql/test.my.conf
[client]
user = www
password = thebigsecretpassword
Then protect the file:
chown www /etc/mysql/test.my.conf
chmod 400 /etc/mysql/test.my.conf
You still have the password in plain text, but it is readable only by root
and
the user that runs the webserver. You can use this to connect to multiple
MySQL
servers as long as the access tokens are the same on all servers.

I realised I'd attacked it from the wrong angle, and some people were kind enough to help out, I did not think it therefore too big a deal to post a specific question related to the previous post, which if anybody puts both posts together will make sense.

Since the keys in perl hashes are case sensitive it makes no sense to

two entries, one with key 'GOTO' and the other with 'goto'.
To make matters worse actual case used for the resulting multivalued key
is only dependent on which field that was parsed first!

Re: problem with $r-push_handlers()
I have traced my problem to the following
subroutine which populates the Hash I use to keep track of mappings of URL's to
Modules (handlers)to use.
As you will see, at the very end of my parse_file
subroutine I have two lines commented out. IF I uncomment these lines out, I end
up overwriting the data in my hash with the clean data I supply. When I do this
my Apache Multiplexer (the thing which does the
$r-push_handlers($handler_bf)) works fine and all is fine. However if I
leave the line commented out - as is here - I get the following
error:-
[Tue Sep 17 22:41:35 2002] [error] Undefined
subroutine MyMod::Apache::Test1 called, GEN2 line 2.
So I'm at a loss, any further help you could give
would be useful,

Here is a sample file:-

Subject: problem with
$r-push_handlers()
All,
can anybody provide any help with this
problem - and maybe explain why I get the following
anomoly?
I've been trying to find the cause of the issue
but to no avail:-(
I have MyMod::Apache::Test pre-loaded in my httpd.conf file.
Here is an extract of code:-
($handler is defined from a Hash defined within
this Code)
($handler_bf is defined from a hash exported by a
module used in this code. to get to the stage in the code where the following
lines commence, I already have read the value from the exported hash and it is
held in the variable $handler_bf)
#$r-push_handlers(PerlHandler =
$handler);$r-push_handlers(PerlHandler =
$handler_bf);
print STDERR "They match\n ($handler) = ($handler_bf)\n" if ($handler
eq $handler_bf);
When I run the code I get the following error:-
MyMod::Apache::Multiplex Matched /test/ to MyMod::Apache::Test
(MyMod::Apache::Test) for /mod_perl_push_handlers: Not a subroutine name
or CODE reference! at /usr/local/lib/perl//MyMod/Apache/Multiplex.pm line
101.They match(MyMod::Apache::Test) =
(MyMod::Apache::Test)
WHEREAS if I use the following code:-
#$r-push_handlers(PerlHandler =
$handler);$r-push_handlers(PerlHandler =
$handler_bf);
print STDERR "They match\n ($handler) = ($handler_bf)\n" if ($handler
eq $handler_bf);
It works and I get this output :-
MyMod::Apache::Multiplex Matched /reconciler/test/ to MyMod::Apache::Test
(MyMod::Apache::Test) for /They match(MyMod::Apache::Test) =
(MyMod::Apache::Test)
So I'm still at a loss. I've tried checking for tainted variables as the
handler hash which fails is populated by reading the contents of files,
whereas the other is simply defined in the script.
I'm guessing this is something more subtle like a configuration
problem.
I've tried stopping a starting apache after making each change to the
script. so each test is run on a fresh server.
Anyway, Answers on a Postcard please:-)
Regards
Marty
Re: problem with $r-push_handlers()
You are a star!!!
I ammended your syntax slightly
and did this:-
my $sub_string='sub { '.$handler_bf.'($r) };';
$r-push_handlers(PerlHandler = eval $sub_string);
Otherwise The handler routine of my handler module doesn't get passed the
Apache object as it's first argument.
It seems to work fine. Thank you.
One point to ask, Is this less efficient, as I'm passing an anonynmous
subroutine around rather than a code reference?
I can finally go to bed :-)
Kind regards
Marty

Re: [Q maybe OT] forward
Hi Perrin, first of all please excuse my late answer - lots of things in mind to care about, as I'm hopefully close to releasing the 0.2 version of the serverpage implementation (and besides I urgently need a new job, too). But thank you for your presice statement, that is exactly what I needed, and you helped me a lot. I think that it'll be a consice offer to the programmer if I declare 'redirect', 'moved', and 'forward' to be events on which enclosing handlers have to react approximately. Which means that a 'redirect' should lead to a 301 response, a 'moved' to a 302, and a 'forward' to whatever. But these are in fact not of the server page's concerns. Would you agree with this approach? regards M Perrin Harkins wrote: Martin Haase-Thomas wrote: forwarding is a term that i borrowed from the JSP concept - which i'm currently trying to implement in perl.

Re: [Q maybe OT] forward
Hi Andrew, thanx for the idea to have a look at Apache::ASP. I took that look meanwhile and to me that seems to be an overhead. Maybe I'm naive, because it wasn't much more than a glance, but the code copes with things a server page *never* has to worry about, things like session handling and so on. Apache::ASP looks more like a Java class packet (you know: one of these endless stories that java people use to wrap their code in - but I don't linme java, as you already may assume...) than a perl module. In my understanding a server page is nothing but a document that has to be processed by the server, and the result of this process is sent to the client. All the other aspects of a web application, like sessions or cacheing or th like ar not what the page itself has to care about. It either knows the respective values, because the handler passed them through to it - or it doesn't. But maybe I'm bragging now - wait a few weeks and we'll hopefully both see whether I'm right or not.

(as far as i've understood it do far. maybe it's just luxury and i'm going to leave it out.) thank you both for your clues and guesses. i think the best idea will lie in informing the programmer that there has been some sort of an 'event' while processing the page - and leave the uncomfortable decision what do to with this 'event' up to him... ... whistling ... :) M Per Einar Ellefsen wrote: At 07:44 24.04.2002, Martin Haase-Thomas wrote: Hi all, maybe this is going to be a little off topic, but it won't take you much time: I am quite certain that recently I saw a server response code concerning forwarding.

Trapping browser events
I am using Embperl on an intranet system to perform complex database searches and display the results. My problem is that, depending on the parameters given by the user, some searches can take some time - returning thousands of rows, and there is a danger that the user will hit the stop button, execute the Back command or even close the browser session altogether. If this happens at the wrong time, an oracle connection could have been made, but no SQL sent to it, leaving an Oracle process hanging there. I need to be able to trap these browser events, and I can then call a cleanup routine to close any database connections. I can use the Javascript onUnload event, I can't figure how to commmuncate with the Perl process. Any ideas would be welcome. Martin Harriss Cambridge UK

[OT?] What exactly is forwarding?
Hi all, I know this is not perfectly the right list for my topic, but before subscribing to another for just one question... forgive me if I'm going to be boring. Even more, because my question is rather philosophical. If you consider JSPs, there is a tag called jsp:forward page=... /. My question is: how do I have to understand 'forward'? The java documentation isn't that verbose, and I can imagine two possible meanings: 1. Forwarding is some sort of an internal redirect to the servlet engine which the browser will not be informed of. From this point of view forwarding will be nearly the same as a dynamic include. 2. Forwarding is the same as a redirect. Maybe a superfluous question for some of you, for me it isn't actually.

Sorry Martin, but this is incorrect. There is no signal SIGWARN.
$SIG{__WARN__} and $SIG{__DIE__} are special perl signal handlers,
which accept the string as the first argument (actually expect a
list). This has no effect:
perl -MCarp -le '$SIG{WARN} = sub { Carp::cluck (received signal
shift() at line.__LINE__) }; warn doh, doh'
dohdoh at -e line 1.
While this does:
perl -MCarp -le '$SIG{__WARN__} = sub { Carp::cluck (received signal
shift() at line.__LINE__) }; warn doh, doh'
received signal shift() at line1 at -e line 1
main::__ANON__('dohdoh at -e line 1.^J') called at -e line 1
The Carp::cluck trick is correct, unless someone somewhere redefines
$SIG{__WARN__}.

Re: Apache::DBI
(doesApache::DBI overload the DBI methods?)
No, it doesn't. It uses Apache and DBI. Did you install the package via the
"Makefile.PL" stanza? Maybe you should just install it another time. On the
other hand, Apache::DBI doesn't export anything. Try calling it with the
package name explicitly.

QUESTION
Hi all,
I hope there'll be someone here to help we with a mod_perl prob, of
which I thought first it wouldn't be one. I refer to the "Writing Apache
Modules" book by Stein/MacEachern.
The prob is quite simple: I have to redirect certain requests under
certain conditions to another URL (and please believe me: I tried with
mod_rewrite, this way seems to be more efficient). I'm using Apache
1.3.22 on Debian Linux 2.4.17.
These are the lines from my httpd.conf:
PerlFreshRestart On
PerlTaintCheck On
PerlSetEnv SHORTNAMES /etc/apache/shortnames.txt
PerlAddVar PROJECT_DOCUMENT_ROOT
/home/disp05/app/fn/
PerlRequire /usr/local/sbin/appstart
Location /
SetHandler perl-script
PerlHandler Apache::StaticServer
/Location
The stanza in StaticServer.pm that fails is:
if ($redirect = $shortnames-get($fname, WAIT, 1)) {
if ($redirect !~ /$r-server()-server_hostname/) {
$r-content_type('text/html');
$r-header_out ( Location = $redirect ); $log-debug($redirect);
return REDIRECT;
}
...
}
$shortnames is an Apache::SharedMem segment, containing a vast amount of
shortnames as keys and the corresponding URLs as values. The funny thing
is now, that although I do everything exactly as I find it in the book
on p.125 (content_type, header_out, REDIRECT), I get pure nonsense.
This is what a libwww-perl client displays when I try to access the address:
500 (Internal Server Error) unexpected EOF before status line seen
Client-Date: Wed, 06 Feb 2002 13:40:25 GMT
This is what I find in access_log:
192.168.255.75 - - [06/Feb/2002:14:46:24 +0100] "GET /psycho HTTP/1.0"
200 - "-" "libwww-perl/5.50"
And this is what stands in error_log:
[Wed Feb 6 14:46:24 2002] [debug]
/usr/local/share/perl/5.6.1/Apache/StaticServer.pm(45): [client
192.168.255.75]
http://www.domain.de/app/fn/portal_welcome_jsp/52329.html
The error log proves that the second if() matches, as the entry comes
from my $log-debug(...).
Has anyone got an idea? I'm close to depression -;)
Many thanx in advance
Martin

asp perl problem
Hi I am new to perl and would like to make a asp page with a script that will find all files in a given directory and create links to different files in another directory. The two sets of files are images (thumbnails and big pics) so I would also like to show the thumbnails on the page and have the links to the bigger pics. I already have all the images and do not need a thumbnail generator. I just want it so that when I add new images thats it. I am not asking for a complete answer only a pointer towards which functions would best do this job etc. Any help you can give would be great. Ju. This e-mail, and any attachment, is confidential. If you have received it in error, please delete it from your system, do not use or disclose the information in any way, and notify me immediately.
Re: API Design Question
On Friday, June 29, 2001, at 07:25 , Shawn Devlin wrote: What advantages do I gain by grouping the functions based on functionality? As per my response to Mr. Worrall, one of my concerns with placing each function call into its own module is the amount of memory used by the various .pm files that will be loaded numerous times. I can see that grouping functions based on functionality would reduce the number of .pm files in memory. However, if I go that route, then would I not be better just to leave the API as one file? A good reason for grouping related functions is not so much functionality as common dependencies, and ease of change management. If everything is in one huge module, then change management become tricky, especially with multiple developers. Giving every function its own module avoids this, but can make tracking down dependencies tricky (and there may be a small memory overhead for each module, but I've never looked). A happy medium is to group together functions that share a dependencies on underlying database objects. For example, if you have a family of library functions that retrieve, insert, update, or delete user records, it might make sense to group these together in a module. If you need to add a new field to your user records, then you change only that module (as well as any changes required to your scripts).
Re: Is ProxyPass the best you can do?
Squid is the alternative mentioned in the mod_perl_tuning.pod that comes with mod_perl. Alternatively, you could try using mod_rewrite, to direct requests for scripts to a different apache instance (e.g. running on a separate port or ip). I've never tried this, but it should work. Squid might be more efficient. cheers, Martin On Sunday, June 17, 2001, at 03:43 am, Philip Mak wrote: I've been thinking about the ProxyPass technique for coping with mod_perl's high memory usage (setup a non-mod_perl httpd that handles all requests, but ProxyPasses the mod_perl calls to a mod_perl enabled Apache). I find that the complexity of this method is more than it should have to be. For one thing, ProxyPass only works on a directory. But if you have images and scripts in the same directory, this is a problem (and it's convenient to be able to have them in the same directory, so that your scripts can a href=image.jpg instead of a href=/images/image.jpg especially when you have a lot of images in different directories).

Re: Perm Module VM_Monitor (fwd)
It can be a real nightmare getting it all compiled and working, especially if you're not on Linux, but it is worth it in the end. I strongly recommend building everything yourself from the ground up, wherever possible, especially if you're working in a production environment. Vendor-supplied versions are often subtly different from the public distributions, and when you do need to recompile for some reason (e.g. mod_perl, or Apache modules that don't play nicely with your current build) you don't want to have to wait for your vendor to pull their finger out. The perl sources are obtainable from http://www.cpan.org/src/stable.tar.gz There is additional INSTALL documentation for AIX. It looks like you will need one of a couple of vendor supplied compilers, or gcc and some sweat. The mod_perl source does contain some stuff about patching the perl sources for AIX. This is intended for use by the 'ubiquitous' patch program (also written by Larry Wall). Try 'man patch' or 'which patch' on your system. If you don't have it, there's a Gnu version you can get. If you have trouble getting patch working, just try and patch the sources manually :-) Once you've got your patched version of perl up and running (it may fail a few obscure tests ... on Mac OS X, perl 5.6.1 failed on 4 tests), the rest *should* be fairly straightforward ...

Do you have any other documentation. I realise some of the problems we incurred are self inflicted. We are using Apache under the guise of IBM's websphere products on AIX 4.3.3 with RS6000 servers. We thought that the VM-Monitor would be very useful, however our knowledge of Perl and C is extremely limited. One of our Unix Admin guys had a go with the following results. 1) Spend three hours finding out about CPAN modules and picked up one very important fact - mod_perl needs to be installed/configured beside the webserver before any of this could be used. 2) Spend another couple of hours finding the source code for mod_perl and getting it onto a test node. Now the fun starts 3) Need a C compiler to compiler mod_perl and the test node didn't have one or I had to find/download/installed/compile gcc on to the node 4) First failure trying to compile mod_perl was that it needed perl (pretty obvious with hindsight). So I moved the C compiler and the mod_perl build environment to the unused HUB system (as PSSP comes with perl). 5) Oops the packaged version is not at a high enough level. I found an AIX perl runtime on the BULL site at the minimum level required and installed that. 6) Now the instructions on mod_perl are invalid for IHS and building a DSO so it took at bit of time to find a Web Site with the relevant flags listed. 7) Now the apxs system (api extensions) failled as the file appears to be misconfigured - there are no instructions anywhere on what it should be so a little bit of trial and error was required to get passed this bit. 8) Now the C compiler requires a file that doesn't exist and does say what should be in it. So time to move C Compilers - I installed the IBM C Compiler to see if that gets a further. 9) Link errors about symbol tables - will this hell ever end. The compiler couldn't find a symbol table in one directory (it was in another one) so a symbolic link came about. 10) Hurray - I finally get a copy of libperl.so created with no errors. Time to test it with IHS. 11) Bugger - segmentation fault everytime its called - another search of the internet shows an article saying that for AIX a patch must be applied to the perl distribution before mod_perl is created. It lists all the relevant C code but gives no indication on how to apply it or in which file. Yet more digging makes me think the patch would have to be added to the perl source code and the recompiled - as I don't have the source its a dead end. ANY help would be gratefully appreciated.

dyld problems with Apache 1.3.19 and mod_perl/mod_php on Mac OS X 10.0.03
I'm having some some difficulties with Apache 1.3.19 and mod_perl/mod_php. Everything builds fine, but I get dyld multiple definition errors in some circumstances. I believe this is connected to the OX X dyld's insistence on freaking out with multiple definitions (so non Mac OS X users might like to stop here) but I'm not sure what the fix is. I've spent quite a long time on this, and am getting quite desperate. Any pointers would be very helpful. I'm used to using persistent database connections under mod_perl and Apache, via the Apache::DBI modules, and Tim Bunce's excellent DBD modules, on Linux. I also like to build everything myself. So, I downloaded and installed Perl 5.6.1, Apache 1.3.19, mod_perl 1.25, mysql 3.23.36, the Msql-Mysql-modules 1.2216, DBI 1.15, Apache::DBI 0.88 and php 4.05. After some fiddling, and with some help from Mac OS X Hints and Stepwise (Thanks especially to the macosx-perl mailing list, Scott Anguish at Stepwise, and Merlin Tishauser [EMAIL PROTECTED]), I got everything to build. I also got persistent database connections to a mysql database. When I added mod_php to the build, via apxs, my apache build started dying on startup, with the following error message: dyld: /usr/local/apache1.3.19/bin/httpd multiple definitions of symbol __dig_vec /usr/local/apache1.3.19/libexec/libphp4.so definition of __dig_vec /Library/Perl/site_perl/5.6.1/darwin/auto/DBD/mysql/mysql.bundle definition of __dig_vec /usr/local/apache/bin/apachectl start: httpd could not be started I tracked the error down to a startup script that I run via a PerlRequire directive (see the mod_perl docs), to open an initial database handle, and load various perl Modules. Commenting out the PerlRequire stopped the error, but when I requested my test_database.pl script (which runs a simple select on the database), from a mod_perl directory, the browser hung, and similar dyld errors appeared in the error log. Strangely, a copy of the script that I keep in in a non mod_perl cgi-bin directory runs with no problem. Within the script, the errors originate with the line use DBD::MySQL, or at an open connection statement, which is effectively the same thing. I think what is happening is that the __dig_vec symbol being loaded from the DBD::MySQL bundle is conflicting with the same symbol in mod_php. I looked in the Apache 1.3.19 source, and can see handlers for multiple definition in os/unix/os.c, but I guess that the DBD::MySQL module is being loaded by code in perl or mod_perl. I guess my question is, is there an easy way to fix this conflict, or do perl and/or mod_perl need to be patched with similar dyld error handlers to the ones in Apache (see os/unix/os.c)?

hi, due to some fairly complex issues (money, or lack thereof), I am considering turning a mod_perl server from co-location into a 'virtual server' service, like Verio offers. Far from asking if it is a good solution (I know it is not) I'd like to know if its feasible. I have been managing remote co-located servers for quite a while, so I am already used to the impotence of not being able to kick the box when it misbehaves. In fact, last time I got really angry at a box I got a my fist cut, hitting it. So remote boxen might turn out to be healthier for my temper ;) Is anyone using a 'virtual server' succesfully? Or have a horror story? Know of companies other than verio? Oh! and before anyone points it out, yes, it low -- low -- low traffic. The current server never gets more than 0.5 load average. Martin
Repost: Anyone using virtual server for mod_perl hosts?
As many people understood I mean some kind of virtual host service, I would like to restate my question. There are companies (Verio at least) offering a 'virtual machine' running a virtualized OS. Verio is offering NetBSD and Solaris. They have a seriouly large iron where many virtual machines run, each virtual machine gets a share of CPU, HD and RAM resources, an at least an IP address. In there is a full OS, and you get to be root for about $150 a month. It's a cheap alternative to co-location, a middle ground between a good virtual hosting service and owning a box. You can run your own MTA, compile whatever the hell you want, etc, although they offer a bunch of services out-of-the-box and have a lot of useful --if annoying-- cron jobs rotating your logs, monitoring the temperature of your daemons, feeding the dog and whatnot. Of course, you get to share resources with a bunch of other customers. It seems a great environment to set up a low traffic / highly customized server, like apache+mod_perl. Now, I know and understand the services they offer, but I have never actually used one with mod_perl. Now, has anyone tried this services? Do I have to worry about anything? Why didn't Stas list them in his article? -- they don't appear in the Guide either -- Do they have a fundamental or practical flaw I can't see? Martin

Unluckily, I wasn't root, so I could not do much there. Of course, if someone is eating up resources, I'll have to fight them... spawn a few mod_perl processes in core, and I guess every other virtual machine will be running from swap ;) m
Re: Making PHP and mod_perl live together in Apache 1.3.14.
Mr Wells, I have succesfully built them together following this procedure. I am also including mysql and imap support in PHP.

[OT] All of Perldocs to HTML files
Hi,
I know this is is wy OT. Kick me privately, please. I am looking
for a way to dump all of the available perldocs into an organized HTML
structure. Activestate people are doing it in their standard distro --
but I couldn't find how. They even get cross-module links ("See Also")
just fine.
Is there a know script for that? A canonical way to do it?

[OT] Problems preparing a module for CPAN
hi, once again, steering off-topic ... :( I've got a nice little module (Mail::Vmailmgr) I am trying to bundle in the standard CPAN fashion, so that it has a proper Makefile.PL, etc. I am following my Perl Cookbook, recipe 12.8 ... steps taken: % h2xs -AX -n Mail::Vmailmgr % cd Mail/ % vi Vmailmgr.pm and wrote all of my module there, picking what h2xs had prepared. Now when I follow the next step, it fails: % make dist make: *** No rule to make target `dist'. Stop. And neither `man perlmod`, `man perlmodlib`, CPAN or O'Reilly's errata page has any hint ... Now many fellow hackers here seem to be releasing successfully to CPAN... so ... what's the secret? What am I missing? (a neuron or two, maybe?) martin
[OT]Problems with `use locale`
hi, sorry for being so OT. The problem is showing up in a mod_perl app, but it's certainly not related at all. Dealing with Spanish as we are, we always have problems with regexp, uc() and lc(). I've found that on my dev box, just adding `use locale` at least uc() and lc() would work allright (meaning ñ got changed into Ñ properly). Now I've built a customer's machine with a newer distro and my uc() is broken where it was working. The devbox has RHLinux 6.1 and perl 5.005_03-6 The customer's box has RHLinux 6.2 and perl 5.005_03-10 And the output of `locale` and `locale -a` is identical on both boxes. Unluckily I'm not about to downgrade the box to 6.1 ... it's a complex Compaq beast that doesn't like 6.1 ... Have you seen anything similar? have any pointers? flames? rants? Thanks! martin

It's not nice to see a large app written in PHP... at least not this one. I have this dangling idea of building a TWIG lookalike (in Perl), with a 'plug-in'/'module' structure, so I may write the email client, and others fill with their desired modules. Anyway, it's a seriuos undertaking, but it's in my plans to rip as much code and design choices from stable OS webmails as possible. It's just a way to soak up all my holidays in perl code ... martin

brian moseley wrote: (speaking as the author of a proprietary mod_perl webmail...) DO IT!! my fear is that writing it as a mod_perl app, it'd be terribly niche, and we wouldn't get it rolling. I'd rather write a bunch of modules, that can be called from a CGI or a templating system. Then those modules can be reused on other apps. Plus, we should be writing that is pure-CGI compatible -- y'know, we won't be needing any actual mod_perl hooks, and CGI-compat means is more usable under other configs, and keeps you honest. martin

Use News. Use mysql, Postgres, MySQL, or none. Use cookies or encoded links for state. It's *very* flexible, and I've come to like that a lot. That's why I'd like to base most of my design choices on it. martin
Mem Sizing tool [was: splitting the code sets across more than one mod_perl server]
hi, [now to the list, also] maybe all of these mathematical formulae can be made into a smallish perl script that grabs this info from `top ax`. I am not sure that top is the proper source of memory usage across platforms. In fact, as I am not a unix old-timer, I should be asking *where* to get that info reliably from. With that info, I could prepare such a script ... it'd be quite useful, I'm building a few servers with very low memory. Stas wrote (privately) that there is no consistent cross platform command that will reliably report memory usage for a given set of processes. He also mentioned Apache::GTop, but I was thinking about an external script. A script I can call from the command line and will evaluate my three HTTPDs and their children, and report global and detailed memory usage. It should be a general purpose tool, not something mod_perl-dependant at all. It might be system dependant, of course. It could be checking what OS it's on and call the proper command accordingly. martin
