Hi, Is there any way to support either stack branching or heap-allocated stack frames in llvm? What I am after is non-preemptive threading support (as in Modsim, but I have also written a small library in asm to allow this in C), where a function can "suspend" itself and resume execution later. I was excited to find llvm as I thought it would be an excellent back end for a language

I recently had a problem with Winbind where new Active Directory user accounts could not access the list of shares on a particular Samba server. "wbinfo -u" showed that the users did exist, but they were not appearing in "getent passwd" results. "/var/log/samba/winbind.log" showed the following error (with Winbind error logging set to either 2 or 3): idmap Fatal

HI, Is it possible to specify CONFIG_PREEMPT_RT=y in the Dom0 kernel? It seems that it is forbidden as it is not a menu option in make menuconfig and gets removed if I manually add it to the .config. I want to run a sound server on Dom0 and am having problems with xruns at present, so need to be able to run a preemptive kernel. Thanks, Chris _______________________________________________

When calls were made to test 3.0.4.rc1, I followed up a few days afterward for the latest SQL Server adapter. Santiago was nice enough to pick up on my ticket for a calculation bug [1] and got it committed to master [2] and then 3-0-stable [3] so it can make it in the next release. I just ran my test suite on the tag of the repo and it appears these did not make it in the v3.0.4 release. How did

...this situation is "try harder". This is particularly challenging when you are trying to remotely debug over such a link, and SSH gets "stuck" even when some pings are getting through. Proposal: I suggest a --flaky option, which would do 3 things: * forward error-correction: preemptively transmit each packet 3x (both from the client-end and the server-end) without waiting to find out whether it was lost. * tweak the TCP timeout-timer for this connection to < 0.5 second, i.e. be much more aggressive about when a packet is deemed to be lost, and is re-requested. * If interactive...

...obably be good to check replication daily, perhaps even more often and generate alerts should we see errors. ? Are there other checks that would be good to do too? [I also use "samba-tool dbcheck --cross-ncs" ]? And any suggestions on how often one might suggest doing them? ? And I'll preemptively ask, do these checks return zero when they have no errors? [If I automate these checks, knowing the proper return values would be good.] ? TIA ? -Greg

Hi. I recently migrated two machines from ext2 to ext3. Kernels (nearly identical) are 2.4.9-ac9 + preemptivity-patch + wrr-patch. The Installations are based on Mandrake 7.2 + 8.0. Also I have e2fstools-1.23 newly compiled on them. Both machines have two ext3 partitions (root + multimedia-data). On one machine I see a .journal file on both partitions, on the other machine (Mandrake-8.0)

...t implement both the advantages above, but your > suggestion would take us further away from that than Vince's version. Aha, looks like both Vince and I overlooked this point. So IIUC we would need to make sure a GPU buffer is only ever mapped once by the IOMMU. This means we either need to preemptively entilery map it at some point and just keep a reference count, or keep track of which 128k ranges are already mapped (again, with a reference count to know when to unmap them). First solution is tempting because it is simpler, but surely there is something wrong with it?

...f such scenarios. Suggestions: 1) In order to avoid name clashes/unintended overwrites, how about switching to a coding paradigm that explicitly (and automatically) includes a package's name in all its functions' names once code is turned into a real package? E.g., getting used to "preemptively" type 'package_fun()' or 'package.fun()' instead of just 'fun()'. Better to be save than sorry, right? This could be realized pretty easily (see example below) and, IMHO, would significantly increase transparency. 2) In order to avoid intended (but for the user often...

But you can easily get the same behavior from...

Hi All, Well, despite my general idiocy I've managed to get PDC and roving profiles working perfectly in my test situation. Obviously, this isn't good enough since computers are the devil, so I've run into some more problems. Fortunately for the Samba team, this isn't a problem with Samba - I think it's more a problem with how our network is set up here. Basically,

...e.img. When a domain using qcow.img is created qcow.img is owned to qemu, but base.img is not. Instead of chown'ing, will libvirt provide an error that could cover both these situations? The virt-manager GUI (or virsh TUI) could interpret that error and chmod the proper files transparently, or preemptively chmod the required files. Users of the libvirt API would have to make sure things are setup properly at first and would not have to worry about side-effect changes made by libvirtd. I think the suggestion holds even if is only the qemu driver doing the chown. Best, matt

You and Cameron are saying that the traffic in France is awful, and some friends who went to Italy didn't go through France.

Hello, I just discovered Gluster a couple of weeks ago and went through the initial documentation and got it compiled. It looks very promising both for my home network and for work. For now I'm concentrating at home - We have to Ubuntu 8.04 desktops, one for me and one for my wife. We generally try to keep them off when not used but at any time any one of them could be up or down. I was

I''m using the SimpleText recipe and Augeas plugin to modify files in place. I''d like to notify the appropriate File resource that a modification is about to take place so puppet can backup the file. Maybe this is already possible but I haven''t found any examples or documentation on how to accomplish this. I think a natural way to do this would be to use the subscribe
