[mp2] 'make test' fails <at> "dyld: Symbol not found: _dav_register_provider", but apache & svn are OK ...


hi,

i've built:

	perl 588
	apache2 (worker-mpm) (httpd 224-dev, apr 128-dev, apr-util 128-dev; 
all r451784)
	subversion 141-dev

and,

	mod_perl2-dev r451853

on OSX 10.4.8.

apache & subversion bothh build & executeOK.

mod_perl build seems to complete w/o error.

but, on 'make test', i see:

	setenv APACHE_TEST_USER  www
	setenv APACHE_TEST_GROUP www
	setenv APACHE_TEST_HTTPD /usr/localapache2/sbin/httpd
	setenv APACHE_TEST_PORT  8529
	setenv APACHE_TEST_APXS  /usr/local/apache2/sbin/apxs
	
	cd /usr/ports/mod_perl_svn
	sudo -u www make test

That's not what I would expect to see on my Linux setup, but it's also
not bad.  You can easily control such slow growth with
Apache::SizeLimit.

Re: possible memory leaks, FreeBSD,mod_perl/1.29


Yeah, obviously I was wrong assuming that it should not grow in case there are 
only the core modules loaded.

If I put Devel::LeakTrace at the beginning of the Apache module, it gives 
several warnings about leaks being found in Apache::Constants::Exports, 
Exporter ?!, mod_perl and the Apache module itself.

Anyway, I haven't dug deeper into it yet so I cannot tell anything more.

Regards,
Assen

Apache::DBI and pnotes

    Hi all!
    I have some simple scripts, on my web server. Each of them have to
do some tasks with database, so the first what I do in the handler is:

my $database_connect = DBI->connect(
 'dbi:Pg:dbname=$database;host=$host,
    $user,
    $password
  ) || die "Can't connect to database: ".$DBI::errstr;

    As I understand, I may write a handler, which would have such code,
and then use pnotes to export $database_connect variable to other handlers.
    Could anyone give me any example of such tasks ?

Best regards,
Vladimir S. Tikhonjuk

if you are using apache::dbi, you can just repeatedly call connect--  
apache::dbi will catch the connect and just toss you back the  
existing connection

===
but storing pnotes is just

handler 1
	$r->pnotes( 'database_connect'=> $database_connect );

handler 2
	my 	$database_connect = $r->pnotes('database_connect');

The main problem with this is that if you loose your db connection somehow, you
wouldn't know until it bombed out on you unless you constantly check it
everytime before you use it.

If you create a simple sub in your handler (or handler base class if you use
multiple handlers) that calls DBI->connect() and use Apache::DBI, it will take
care of all that checking for you and make sure you have a connection (if one
can be made).

does apache::dbi ping a connection then reconnect if the ping fails?

If you call DBI->connect it does.

What do expect/see on your Linux setup ?
