For\nexample, if $stopped is the commit you interrupted it at,\n\n git update-ref refs/remotes/git-svn $stopped^\n\nAdjust the ref name if you used a trunk/branches layout.

At least\nthat ref corresponds with a file relative to the .git-folder.\n\nYes, I use a trunk/branches-layout... but I'm fetching a branch that\nhas been moved (multiple times), so git-svn seems to try to fetch\nsomething called \"trunk@54516\"... perhaps the \"@ 54516\"\n\nAnyway, I tried doing the following:\n\ngit update-ref refs/remotes/trunk/git-svn \nrm .git/svn\ngit svn fetch\n\ngit then outputs something like this:\n\nr = \nr = \n...lots and lots of these...\nr = \nr = \nr = \nr = \n...some more lines...\nr = \nDone rebuilding .git/svn/trunk@/.rev_map.\nIncomplete data: Delta source ended unexpectedly at /home/erifay01/\nlibexec/git-core/git-svn line 4249\n\nThis is basically the same thing I'm getting if I just delete the .git/\nsvn-folder and re-fetch. For the record, I decided to roll-back about\n10 more revisions than where I terminated, just to be sure.\n\n\n> Failing that, you could test if this also happens when only looking at\n> a few surrounding revisions, for example if the failure was around\n> revision 100:\n>\n> mkdir ../new-test\n> cd ../new-test\n> git svn init \n> git svn fetch -r 95:105\n\nThis turns out to be a bit more tricky than I expected. You see, the\nproject has moved inside the repo multiple times during it's life-\ntime, and the revision where I broke the fetching is at an old\nlocation.\n\nSo I tried fetching if from old location:\ngit svn init -s .\ngit svn fetch -r :\n\nDoing the fetch outputs nothing (git svn init outputs \"the usual\nstuff\", though). Trying to do the same thing with the new path (same\nas above, but with set to the path of the new location)\ngives the following output:\n\nPath '' was probably deleted:\nFilesystem has no item: REPORT request failed on '/!svn/bc/\n':\nFile not found: revision , path ''\n\nWill attempt to follow revisions r .. r committed before the deletion\n\n... And then nothing.\n\nSo, I'm still quite lost here. It might be that a full re-clone is\nwhat is needed.\n"},{"id":"104020","messageId":"20090210151048.GA27171@bit.office.eurotux.com","threadId":"17694","inReplyTo":"200902101442.32772.trast@student.ethz.ch","subject":"Re: git-svn: incomplete data after terminated \"git svn clone\"","fromName":"Luciano Miguel Ferreira Rocha","fromEmail":"luciano@eurotux.com","sentAt":"2009-02-10T15:10:48Z","receivedAt":"2009-02-10T15:10:48Z","isPatch":false,"sender":{"key":"luciano@eurotux.com","avatar":null},"body":"On Tue, Feb 10, 2009 at 02:42:29PM +0100, Thomas Rast wrote:\n> Failing that, you could test if this also happens when only looking at\n> a few surrounding revisions, for example if the failure was around\n> revision 100:\n\nUsually this happens to me due to server closing my connection and/or\nstarting ignoring me.\n\nA full clone for some projects takes too much time and bandwidth...\n\nRegards,\nLuciano Rocha\n\n-- \nLuciano Rocha \nEurotux Informática, S.A. \n"}]}
