Should probably have mentioned\nthat...\n\n> Anyway, what's the best option?

It does appear that there's a write() call somewhere in\ngit-svn that still isn't protected by an \"or die\", however, because\nwe're getting an invalid checksum without getting a write error first.\n\nIn any case, if the problem is a giant file that won't fit in /tmp,\nthe best we could do in git-svn is produce a better error message.\n/tmp is still the \"right\" place to put temp files. I agree with the\nsuggestion to try pointing the TMPDIR environment variable somewhere\nelse... or else make your /tmp bigger.\n\nHave fun,\n\nAvery\n"}]}
