I don't know what PK is.

Gavin,

As others have reported, this seems to fix the main speed issues people
were complaining about.


But it doesn't seem to have changed the overload referencing semantics
that DBIx::Class::StartupCheck tests for - this still fails on the new
perl:


Two things, firstly - no one else in any of the bug reports has
mentioned this DBIx issue - so, I am happy to ignore that in this bug
case specifically since it does not break what was previous behavior.


Secondly, neither Nicholas nor Vipul have replied to my emails asking
for help, and i think 4 days is a fair amount of time to timeout on.


So unless anyone has reason to not push these perl packages, I'd like to
get them out there.

You might want to allow and extra day or two because of the long holiday
weekend in the U.S. Many folks start it early and come back late, to
mountains of e-mail and paperwork and catch-up activities.

Regardless of the holiday thing, I don't see why you shouldn't make it
available with, at most, a minor caveat for those who want to jump on it.

The C4 fasttrack repo is built in sync with upstream, there is no
fasttrack on C5 ( go look at mirror.centos.org ).


Karanbir,

Is there a reason why there is no fasttrack for CentOS-5 ? I do see
packages available from Red Hat, although I cannot find any fastrack SRPMs
directory on ftp.redhat.com.

Dag,
there has been a bunch of packages released on RH FT yesterday. But I do
not know any special open RPMS source for them now. Maybe on RHN. It
seems to me, that RPMS packages are provided within OS RPMS, see:

http://rhn.redhat.com/errata/RHBA-2008-0646.html
http://rhn.redhat.com/errata/RHBA-2008-0844.html
etc. are in
http://ftp.linux.cz/pub/linux/redhat/linux/enterprise/5Server/en/os/SRPMS/?C=M;O=D

I think that is the major reason... if the packages are not available
from ftp.redhat.com, they are harder to say they are build from
upstream.

I just randomly picked up 7 to 8 packages in the FasTrack errata and
checked to see if their srpms are available. I did find them all at
ftp.redhat.com.

Dag, there is no fastrack SRPMs directory. The files are mixed with
all other srpms.

If your Perl apps are unusually slow on CentOS 5, have a look at
this

blog:

http://blog.vipul.net/2008/08/24/redhat-perl-what-a-tragedy/


Summary: The Upstream Vendor version of Perl has a patch to the
"bless[]" function that makes it /extremely/ slow.


Reliable info heard on the grapevine indicates 5.3 would have the
fix's

required.


So that means about 6 months away from a fix?



Unless upstream bundles a hotfix that is available for people...



Such a hotfix was released in the last couple of days. A big moment
for RHEL/CentOS + Perl users.
