-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello,
> He additionally reports that this is reproducible not only with > 1.5.1, but with Debian's build of 1.6.9. (That mail is probably in > the moderation queue now.) thank you Peter! (To me, this is the first indication that someone actually noticed my attempts to tie that bug down where you folks can hit it.) Peter refers to my attempt to ask the Debian bug tracking system to forward my Debian bug report to this list. Nice try on my part... As that doesn't look like it's getting anywhere, here comes a manual copy. The new information in a nutshell: * Reproducible with Debian's unstable "1.6.9dfsg-1" version, as Peter mentioned, * In all my experiments thus far, the client always has been Ubuntu's 1.6.5dfsg-1ubuntu1. Below comes the whole story as available in the Debian bug tracking system. Basically, this is a summary of what I know at this point. Turn to http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=571457 to follow Debian developments. So far, so good. As for me, I intent to sit back and relax until either someone asks me for further information or else until I receive clearance to introduce this to Subversion's bug tracking system. Regards, and thank you all for providing fine software, Andreas ====================================================== Package: subversion Version: 1.6.9dfsg-1 X-Debbugs-CC: dev@subversion.apache.org Hello, subversionists, I have a subversion repository with a single revision, consisting of a single roughly 10 MB file with random data. I use svnserve to serve that repository. I use a client to access the svnserve over the network, via "svn co". (The client happens to be Ubuntu's 1.6.5dfsg-1ubuntu1, in case that matters.) The server is an openvz guest. When, on the corresponding host, I set vzctl set NNN --tcpsndbuf 415k:715k or lower (my guess is the first number is the one that matters), the checkout starts, there is some initial network traffic, but then svnserve starts to eat up all CPU cycles it can get and no further progress is made, until I kill the svnserve process manually on the server. Just killing the client does not seem to stop the waste of CPU cycles on the server. When I increase the tcpsndbuf above that value, there is no problem. However, when I check in a much larger file into the repository (I do that directly, using file:/// - access), and try to check out again (using svnserve), the problem reappears. This is quite reproducibly, with svnserve as a standalone daemon as well as svnserve running under inetd. For the latter case, I made no precise experiments about the --tcpsndbuf numbers. This is the summary. I have written three mails yesterday and today to the dev@subversion.apache.org mailing list, but have not received any answers there yet. There is lots of nitty-gritty background information in those mails, which, hopefully, you'll be able to find here: http://mail-archives.apache.org/mod_mbox/subversion-dev/201002.mbox/browser Regards, and thank you for providing fine software, Andreas P.S.: I ask the Debian bug tracking system to forward a copy of this mail to the SVN dev mailing list. This contains two pieces of information not available in my previous mails to that list: * The bug is reproducible with the latest subversion software version I can easily install, short of compiling myself. * The client I'm using is, and always has been, 1.6.5dfsg-1ubuntu1. I think I misquoted it to be 1.5 in one of my earlier mails. I apologize if this caused any confusion! - -- Dr. Andreas Krüger, Berater, DV-RATIO NORDWEST GmbH andreas.krue...@dv-ratio.com GPG/PGP Fingerprint 8063 4A9B 362D 4220 A546 14C1 EA19 AADC FD44 5EB7 DV-RATIO NORDWEST GmbH Tel: +49 (0)211 / 577 996-0 Fax: +49 (0)211 / 577 996-26 http://www.dv-ratio.com <http://www.dv-ratio.com> Sitz der Gesellschaft Habsburgerstraße 12, 40547 Düsseldorf Registergericht Düsseldorf HRB 34330 USt-IdNr.: DE811321837 Steuer-Nr.: 809/44031 Geschäftsführung: Günter Gerstmann Prokura: Trudbert Vetter, Uwe Wolfram DV-RATIO - "Kompetenz und Zuverlässigkeit seit 1980" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkuHfvQACgkQ6hmq3P1EXrfSwQCglTixze7pSlyDpl3ZTikWprbR ko4AnR2/sHePNzU2BMeLvrPCRMCL9hxu =vrmm -----END PGP SIGNATURE-----
