Got a weird question here... maybe it's more GIT-related than zen-related, but actually I think, it's really a more interesting question for the users, as well as for the zen-project maintainers...
on the websites they ask kindly not to clone zen twice if one likes to get stable & unstable as well, to avoid unnecessary traffic. what I observed is, that if I dont pull for a somewhat longer period, the pull most likely never applies due to some conflicts...
just some minutes ago I pulled, having zen-3.1.5 as the latest 'base'
it took really long to count like 2.3 mio remote files, to transfer like 450 mb, only to see what I already expected. not applicable due to some conflicts (pls dont ask, dont have that msgs anymore)
then I did, what i always do... backed up my config, recloned stable (with "--depth=1"-switch), and it were only like 86k objects counted, and 130 mb transferred... is that difference related to the pull, which maybe does exactly not what depth=1 does? is it possible to pull with only depth=1 ? I could not find anything related to that...
thanks |

To save you some time and the zen servers several gigabytes of bandwidth, this is the right way to update the tree:

I've always had trouble every time I've tried to use a shallow clone (--depth). It seems like it should be a useful way of saving bandwidth, but it seldom gives me a useful repository.
From the man page for git-clone:
Quote: | --depth <depth>
Create a shallow clone with a history truncated to the specified
number of revisions. A shallow repository has a number of
limitations (you cannot clone or fetch from it, nor push from nor
into it), but is adequate if you are only interested in the recent
history of a large project with a long history, and would want to
send in fixes as patches.
|
So based on the man page, you may not be able to update a shallow clone with a "git pull". |

OK, i'll try that. To clear things up: doing a rebase, the last received commit gets the new base (say A); so a further pull (w/o rebase) applies the corresponding diffs and gets B, and yet another pull (w/o rebase) gets C, but does not only apply the diffs since B, but all diffs since A, as that is the initial base?
So rebasing every time simply reduces bandwidth, if I got that right, as only the diffs for the latest changes are pulled? What about the local overhead? Isn't it reduced as well? Really sounds like a win/win-thing ?!?
Let me know, if I got that right . Thanks |

A --rebase throws away your local working copy for upstream's latest commit then applies any local commits on top of it. Since you're unlikely to have local commits it just updates to the latest with no questions asked.
The default pull does a merge instead, which doesn't work when upstream keeps recycling the master branch name for entirely different trees.
In both cases you're only downloading the changes since your last pull/clone/fetch. |

There isn't any circumstance in which SLUB would beat SLAB? Normally these things depend on the purpose of your local machine, no? Where could I read more about this SLUB vs SLAB thing? (I'm using an i7 and constantly running heavy matlab/fortran tests, with high memory & cpu usage)

I had gentoo running on my other laptop, but the hard drive crashed and I got a different (newer) laptop. I am installing gentoo on my new laptop now (actually, typing from links on the minimal CD!).
When I had gentoo on my laptop, I used zen-sources as opposed to gentoo-sources. I've never had any problems with it. It 'seemed' faster than the gentoo-sources kernel, and it was highly configurable. However, a lot can change in a year so I'm wondering... what is your guy's opinion on zen-sources vs gentoo sources? Is zen-sources an overall better kernel, or no? Whats the difference?
Thanks!

I got most of the data from lkml
slub nowadays might be pretty similar in terms of performance to slab - it also should be as stable as slab (haven't used slab for some kernel releases now),
slab uses somewhat more resources from what I read and slub is tailored toward efficiency in memory usage
for your kind of work or depending on the work load - generally
several components should be crucial (the most important from my experience so far)
- rcu
- slab/slub/...
- CFS / BFS
the other subsystems of course also play a role so you might want to take the kernel-release which suits you best
for me and my hardware (also core i7) & workload (mainly compiling, backing up 1-2 TB of data via rsync, multimedia content, etc.) it's currently 3.3 [where lockless writeback, mmu preemptibility and other stuff is included which got added in the previous few kernel releases]
I'm not observing lkml as closely anymore as in the past, due to lack of time, so I might miss some recent additions / changes _________________ https://github.com/kernelOfTruth/ZFS-for-SystemRescueCD/tree/ZFS-for-SysRescCD-4.9.0

Sorry I didn't make myself clear previously. I actually meant the diff for zen-kernel. |

They got rid of tags. How do you update to latest kernel now. Im lazy therefore im stuck on kernel 3.3.7. |

I added an ebuild for zen stable 3.4.4 kernel in my overlay at http://gentoo.techwolf.net/
I would just attached the ebuild and zen patch here, but there does not seem to be any way to attached large compressed patches here.
edit: I just added 3.4.10 and 3.5.3 from the zen stable branches.

Does anyone else use this on a single-core Atom? I've noticed /proc/cpuinfo lists "cpu cores" now, which is zero for the second hyperthread (makes sense), but lscpu seems to be dividing by that number and now I get a big fat crash. Kinda breaks the distcc setup I was using... |

Yeah, our server is gone.

So does this mean Zen is dying, or just a temporary setback?
