So does that mean we should ignore cogito's whinging about rsync being deprecated? -- Russell King ``` ## Petr Baudis, 2005-07-09 11:55 Subject: Re: Linus kernel tree corrupt?

Yes, please do. I deprecated rsync a day before Linus "broke" http-pull. It's un-deprecated again for now in the latest Cogito. -- Petr "Pasky" Baudis Stuff: http://pasky.or.cz/ be careful, some twit might quote you out of context.. ``` ## H.

It _is_ unsafe for individual objects, and your packfile will be corrupt if you break it in the middle and not have --whole-file turned on, I assume. It would be ideal if we could make rsync allow resuming download of the file if interrupted, but not under the final name but in that hidden file it uses. > sent 339 bytes received 1802 bytes 4282.00 bytes/sec > total size is 410 speedup is 0.19 > Missing object of tag v2.6.11... different source (obsolete tag?) > Missing object of tag v2.6.11-tree... different source (obsolete tag?) > Missing object of tag v2.6.12... different source (obsolete tag?) > Missing object of tag v2.6.12-rc2... different source (obsolete tag?) > Missing object of tag v2.6.12-rc3... different source (obsolete tag?) > Missing object of tag v2.6.12-rc4... different source (obsolete tag?) > Missing object of tag v2.6.12-rc5... different source (obsolete tag?) > Missing object of tag v2.6.12-rc6... different source (obsolete tag?) > Missing object of tag v2.6.13-rc1... different source (obsolete tag?) > Missing object of tag v2.6.13-rc2... different source (obsolete tag?) > New branch: 0109fd37046de64e8459f8c4f4706df9ac7cc82c > Cloned (origin > rsync://rsync.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git > available as branch "origin") > Cloned to ./ (origin > rsync://rsync.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git > available as branch "origin") > > Is the "missing objects" thing spurious?
