Python Problem
Hi,
I have a problem with using python on Scientific Linux 6.0 (Carbon): If
I run a program that throws an exception, the program will hang and
never return unless Ctrl-C is pressed. The simplest program that has
this behaviour is
8-
raise Exception()
8-
Debugging this with strace leads to
socket(PF_FILE, SOCK_STREAM, 0) = 4
connect(4, {sa_family=AF_FILE, path=/var/run/abrt/abrt.socket}, 27^C
unfinished ...
as the last messages. Searching for this points to a big report on
Redhat Enterprise Linux that I do not fully understand:
https://partner-bugzilla.redhat.com/show_bug.cgi?id=614752
What should I do now?
I am also curious about the bug management for Scientific Linux. The Web
page does not mention this at all; what is the place to fill a bug like
this?
Regards
Ole
Digest Format Readability
I get the SLU by digest once per day, and I am having difficulty following the conversations. The posts are all jumbled together and often there is unreadable ascii garbage to confuse things. I've tried a few of the listserv options for encoding and such, but to no avail. I'm reading these on the gmail web interface. Does anyone have any ideas for improving readability (while maintaining digest-mode)? Jean-François
RHEL 5.6 vs. SL 5 ?
Hi, I just took a peek at the download page for SL 5, and I only see 5.5. Does SL 5.6 exist somewhere, or has it never be released? If that's the case, is it simply a matter of install medium, e. g. are the updates for 5.5 (after a 'yum update') equal to a 5.6 install? I'd like to ask specifically, because I'd like to use SL 5 for a webserver, and AFAIK, RHEL 5.6 has replaced PHP 5.1.6 by PHP 5.3, which would be very welcome.

If I start it as python ~/t.py it hangs as described. The home directory is a local disk. When the abrt daemon is disabled, the program does hang, too.

I believe that processor does not support PAE, so you are out of luck. Again, this is a Red Hat decision. The EL6 32-bit kernel is what was a PAE kernel for EL5. Putting it another way, the EL5 32-bit non-PAE kernel has been dropped for EL6 and so what would known as a PAE kernel has had that descriptor removed. Alan.

I'm pretty happy with SL 6.0. +1. Quite some familiar names around this mailing list. As far as I'm concerned, I expected some sort of refugee camp, and I'm the more pleasantly surprised to find it's a four star hotel. Less than 24 hours with SL, and it looks like I'm going to stick with it. I just discovered that the text-based version of Anaconda has been seriously amputated in functionality.

Any know workaround for that apart from installing SL 5.x or buying a new laptop? Cheers, Niki

Although in my case, not only old-style X apps lost their fonts marbles, but so did the KDE programs, menus, etc -- which I didn't think used the old-style X fonts at all. After wasting 15 minutes resetting fonts in many different places, X is usable again. I'm sure Murphy's Law says that this bug will be fixed tomorrow and we'll all have to re-reset things :) Thanks for your posts David and Alec. I thought I was losing my marbles when all my fonts went screwy on EL5/KDE so good to know the root cause. One of the posters in the bugzilla entry noted the -nocpp option on xrdb. The following works great: $ xrdb -nocpp -merge .Xresources I've added it to my session startup commands and helped some users do the same.

intel graphics scrolling messes up page
I get a similar problem as shown in https://bugzilla.redhat.com/show_bug.cgi?id=522763 the screenshot Display of firefox when scrolling window with mouse In firefox it seems to happen only when smooth scrolling is enabled, and I am not using compiz. it generally happens when it is partly covered. i also had this problem in the help viewer. xorg-x11-server-Xorg-1.7.7-26.el6_0.3(x86_64) xorg-x11-drv-intel-2.11.0-7.el6(x86_64) kernel-2.6.32-71.24.1.el6(x86_64) If i use compiz i do not have this problem Any suggestions Thanks Jon

I was looking for some comparison ESX versus KVM, but what I found, was mostly outdated. The one of newest is http://blog.delouw.ch/tag/kvm/ and the described drawbacks should not be a huge issue for an average user, not mentioned the fact, that RH is working to improve KVM. Vackav M.

You've obviously had similar thoughts just like mine . . . but have developed them that bit further. It really depends upon the need for non-PAE 32-bit kernels for EL6. Alan.

It really depends upon the need for non-PAE 32-bit kernels for EL6. My non-PAE-capable IBM T42p Pentium-M laptop is dead ATM from a fan failure, but the possibility of a compatible SL6 release might prompt me to resurrect it. Part of the reason I have not bothered to hack the hardware is the upstream decision to drop support for non-PAE 32-bit systems. As a matter of principle I heartily endorse the idea. There is a lot of functional hardware out there that does not do PAE, but still has life left in it. Phil

Seriously, I am building my first server for virtualisation and KVM works out of the box /two days ;-) /. Becasue libvirt was designed by goats who'd been sniffing too many pheromones. Let's just say that they were not paying attention to Eric Raymond's guidelines on open source GUI's (http://www.catb.org/~esr/writings/cups-horror.html) and leave it at that. Our favorite upstream vendor is usually quite good at writing gui's, having learned a lot of lessons over the years and having strong developers. libvirt is not one of their shining efforts. VMWare, especially its LabManager suite with which I've worked recently, does a much more thorough job. It's not perfect: the update of VMwareTools with kernel updates is hardly perfect, and its interactions with the NetworkManager of SL 6 and RHEL 6 are not good. But I'm not thrilled with NetworkManager in servers or managed environments, either. I've heard good things about KVM performance, but didn't see it in RHEL/CentOS/SL 5.x. I'll be very intersted to see the results of the Debian testing I'm doing in the near future.
