svnadmin dump<\/code><\/p>\nWhat happened was svnadmin dump<\/code> would get partly through it’s export and the connection would inevitably drop. This left me with a partial dump that was really of no value.<\/p>\nGiven the size of the repository (huge) and the quality of the link to the repository (terrible), it was time to find another solution. I still wanted revision history to be retained, so instead of using svnadmin dump<\/code>, I decided to try svnsync<\/code><\/p>\nThe foolproof way: svnsync<\/h2>\n
svnsync<\/code> requires a second repository to sync to. No problem, just set up a local repository:<\/p>\n$ cd \/tmp\r\n$ svnadmin create local.repos\r\n$ echo '#!\/bin\/sh' > local.repos\/hooks\/pre-revprop-change\r\n$ chmod +x local.repos\/hooks\/pre-revprop-change\r\n$ svnsync init file:\/\/\/tmp\/local.repos http:\/\/remote.repository.bfe\/repository_root\r\n$ svnsync sync file:\/\/\/tmp\/local.repos<\/pre>\nI don’t know why svnadmin create<\/code> doesn’t give you a base (empty) pre-revprop-change<\/code>, but it doesn’t, so lines 3 & 4 above are needed.<\/p>\nsynsync sync<\/code> is where the magic happens. It syncs the entire repository one commit at a time. So if (and when) it fails, you can simply re-run that last svnsync sync<\/code> command again, and it will resume where it left off.<\/p>\nOnce that’s done we have to take some extra steps to be able to switch\/relocate any checkouts to the new repository URL. Otherwise subversion is going to complain about the repository UUIDs not matching:<\/p>\n
svn: The repository at '...' has uuid '5242f4d0-6d7c-4812-b150-1df843629073', but the WC has 'add5d305-2225-4d42-af3e-22d1851a68c1'<\/pre>\nSo we need to reset some of the properties on the local copy of the repository. The easiest way to do this is to checkout the repository locally and run a few commands for it:<\/p>\n
$ svn checkout file:\/\/\/tmp\/local.repos local.checkout\r\n$ svn proplist --revprop -r0 local.checkout\r\nUnversioned properties on revision 0:\r\n svn:sync-from-uuid\r\n svn:sync-last-merged-rev\r\n svn:date\r\n svn:sync-from-url\r\n$ svn propdel svn:sync-from-uuid --revprop -r0 local.checkout\r\n$ svn propdel svn:sync-last-merged-rev --revprop -r0 local.checkout\r\n$ svn propdel svn:sync-from-url --revprop -r0 local.checkout<\/pre>\nThe revprop changes are not versioned changes, so they take effect immediately – there’s no need to commit them. Now we need to set the UUID of the local repository to that of the old remote repository.<\/p>\n
$ svn info http:\/\/remote.repository.bfe\/repository_root\r\n...\r\nRepository UUID: add5d305-2225-4d42-af3e-22d1851a68c1\r\n...\r\n$ svnadmin setuuid local.repos add5d305-2225-4d42-af3e-22d1851a68c1<\/pre>\nThe repository is now ready for svnadmin dump (again)<\/h2>\n
With the repository fully copied, and the UUID sorted, you can move it to it’s final destination. If it’s ultimately going to a hosted repository (like repositoryhosting.com<\/a>) you can dump the local repository to use for importing at the new host:<\/p>\nsvnadmin dump local.repos > local_svn_dump<\/pre>\nOnce your repository is at it’s new location, you can switch any checkouts so they’re pointing to the new location:<\/p>\n
svn switch --relocate http:\/\/remote.repository.bfe\/repository_root http:\/\/new.repository.us\/svn_root<\/pre>\nIt should be noted that as of svn version 1.7 svn switch --relocate<\/tt> has been deprecated in favor of svn relocate<\/tt><\/p>\n![](\"https:\/\/www.foell.org\/justin\/wp-content\/plugins\/send-to-kindle\/media\/white-15.png\")
