Thread: P4Perl tagged filelog leaking?




P4Perl tagged filelog leaking?

On 2005 (.1 and .2) servers (both Windows and Linux), we
noticed an
enormous leak using P4Perl (version 3.5396).

The following script will leak:

--------------------------
#!/usr/bin/perl

use P4;
my $p4 = new P4;
$p4->Tag();
$p4->ParseForms();
$p4->Connect () || die "p4 connect: $!";

while (1)
{
	$p4->Run ("filelog",
"//data/...");
}

$p4->Final ();
$p4 = undef;
--------------------------


If you run the script untagged, it leaks a lot less (but
still leaks).
Other commands seem to be leaking (tried info and fstat
amongst others).

Is there a fix/workaround to this, any ideas?

We want to introduce a nightly job that will do a bunch of
"p4 filelog"
and we don't want our server to croak.

Better yet, is there a way to know if a revision is the
source of a
branch without using filelog?

Thanks!

Nicolas

Hi Nicolas,

I'm a bit confused: is it the server that's leaking? Or
P4Perl?

If it's the server, you need to raise this with Perforce
Technical
Support. If it's P4Perl, you've come to the right place,
but I don't
understand how a leak in P4Perl will cause your server to
crash.

Could you clarify what's going on?

Thanks,

Tony
