mirrorlist
by Kostas Georgiou 26 Mar '07

26 Mar '07

Hi, I just noticed that the mirrorlist script returns the full mirror list if the mirrors for your country are below a certain limit. For example here is what happens with most european countries: # repo = core-6 country = GB arch = x86_64 http://zeniv.linux.org.uk/pub/distributions/fedora/linux/core/6/x86_64/os/ http://zeniiia.linux.org.uk/pub/distributions/fedora/linux/core/6/x86_64/os/ http://www.mirrorservice.org/sites/download.fedora.redhat.com/pub/fedora/li… # No results found for country: GB # Defaulting to global .... # repo = core-6 country = FI arch = x86_64 ftp://ftp.funet.fi/pub/mirrors/ftp.redhat.com/pub/fedora/linux/core/6/x86_6… # No results found for country: FI # Defaulting to global .... # repo = core-6 country = NL arch = x86_64 http://ftp.surfnet.nl/ftp/pub/os/Linux/distr/fedora/6/x86_64/os/ http://ftp.nluug.nl/ftp/pub/os/Linux/distr/fedora/6/x86_64/os/ ftp://alviss.et.tudelft.nl/pub/fedora/core/6/x86_64/os/ # No results found for country: NL # Defaulting to global .... # repo = core-6 country = NO arch = x86_64 http://ftp.uninett.no/pub/linux/Fedora/core/6/x86_64/os/ # No results found for country: NO # Defaulting to global .... As it is now only US,CA,FR,DE get a "local" mirror as far as I can see I was wondering if it makes more sense to use mirrors from "nearby" countries instead of the full list in cases like this. Defining "nearby" could be a problem but even the same continent is bound to be better than the existing system. Any thoughts? Kostas Georgiou

Disk space requirements
by Matt Domsch 24 Mar '07

24 Mar '07

Just some stats I ran on the current data posted for the mirrors. Everything (Core + Extras, FC 1 through 6, 7test[12], development, updates, repodata): 492GB FC1: 21.5GB FC2: 35.5GB FC3: 33.1GB FC4: 52.4GB FC5: 69.6GB FC6: 77.5GB development: 50.8GB FC+E6/i386: 22.6GB FC+E6/ppc: 23.5GB FC+E6/x86_64: 24.4GB FC+E6/source: 5.1GB FC6test2: 26.8GB so we're already expecting mirrors to carry ~25GB per arch per release or thereabouts. If we continue with 3 arches, 2 releases per year, that's at least 150GB per year growth. If we add arches, Unity respins, more CD/DVD objects, and the like, it'll grow faster. -Matt -- Matt Domsch Software Architect Dell Linux Solutions linux.dell.com & www.dell.com/linux Linux on Dell mailing lists @ http://lists.us.dell.com

Wiki slowness
by Mike McGrath 20 Mar '07

20 Mar '07

I've been examining more closely why wiki saves are slow. At this time it appears the issue is in notifications. More to the point, determining who to notify. Our wiki supports regex for page notifications. This means that when you save a page, Moin has to iterate over all users (currently about 10,000 registered) before it knows who to notify. Actually sending the notifications doesn't take that long, but figuring out who to mail can take a long long time. My tests show between 30 and 95 seconds. When I disabled notifications saves dropped to 2-3 seconds. I'm not sure what to do from here but it looks like it will take a code change (I'm working with some guys in #moin). I'm continuing to look into it but wanted to let everyone know what was going on. -Mike

Future: Filesystem ACL and SCM
by Warren Togami 20 Mar '07

20 Mar '07

NOTE: This info is not relevant to the near-term Fedora merge or any infrastructure supporting it. We will continue to use the existing CVS + ACL system. Toshio was wondering about the possibility of using filesystem ACL's as part of a future ideal SCM's ACL enforcement. It would work something like this: 1) PackageDB knows about all packages, owners, granted permissions, groups, etc. 2) PackageDB generates xattrs or FS ACL (themselves based on xattrs) within the SCM files/directories. 3) SCM has a custom ACL enforcement script that reads those xattrs, making it very fast and flexible. ACL's could be enforced based on a list of users, groups, or a combination of users and groups. I talked with a few filesystem experts within Red Hat. They said... - ext3 has a limit of 4KB for xattr data. If you use the standard encoding of 8 bytes per uid, that has a limit of roughly 100 entities that could be associated with a file. Is this too limiting? I dunno. Perhaps it need not be too limiting if more extensive use of group-based-ACL's are used. - XFS could possibly allow a maximum of 64KB xattr's per file, but that is very inefficient in filesystem storage. - xattr's are currently not supported by NFS.

Auto: cvsextras -> fedorabugs
by Warren Togami 20 Mar '07

20 Mar '07

Hey folks, If member is sponsored in cvsextras, automatically add to fedorabugs group. How difficult would it be to automate this in the current FAS? Warren Togami wtogami(a)redhat.com

Research Project - Google
by Mike McGrath 20 Mar '07

20 Mar '07

It came to my attention recently that by having duplicate content at www.fedoraproject.com and fedoraproject.org that both would receive a lower ranking in google's system. As a result I've got everything redirecting to fedoraproject.org. My Google-fu isn't that great so I'd like to ask if anyone out there would like to do some research to find out how we can increase our hits. Would a robot file help? I honestly have no idea. Anyone interested? -Mike

puppet and external hosts
by Mike McGrath 20 Mar '07

20 Mar '07

Right now I'm setting up the torrent box to use puppet. In order to do this puppet needs access to lockbox. In order to do this I've decided it best to use ssh forwarding. We've talked about VPNs in the past, and we can discuss it again in the future. For the time being, however, I think I'd prefer to be more surgical. Can anyone think of any issues with doing this? We've never actually made this link before with external hosts, even the fas integration uses a public facing website to wget the info we need. -Mike
