In addition to existing and\ndiscouraged `svn.noMetadata` / `--no-metadata` git-svn would acquire\n`svn.metadata` / `--metadata` / `--svn-metadata` = none | notes | commits\nthat would as one option put 'git-svn-id:' lines or their equivalent\nto git notes.\n\nSecond, from what I understand from the very beginning git-notes \nwas designed in such way that sharing notes is sharing ref.\ngit-replace shares this feature.\n\nBut please take above with a grain of salt, having never used notes\nbefore, and not being developer of this subsystem.\n-- \nJakub Narebski\nPoland\n"},{"id":"168935","messageId":"0DF6602C-9DF3-42B3-AFB1-CDAA71D9E2F0@apple.com","threadId":"27489","inReplyTo":"BANLkTinorqTQOBw46mYJYfEWTEXC+Myzpw@mail.gmail.com","subject":"Re: [RFD] Proposal for git-svn: storing SVN metadata (git-svn-id) in notes","fromName":"Dave Zarzycki","fromEmail":"zarzycki@apple.com","sentAt":"2011-05-29T06:37:45Z","receivedAt":"2011-05-29T06:37:45Z","isPatch":false,"sender":{"key":"zarzycki@apple.com","avatar":"https://avatars.githubusercontent.com/u/1071982?v=4"},"body":"On May 28, 2011, at 8:55 AM, Ævar Arnfjörð Bjarmason wrote:\n\n> One good thing about git-svn's current system is that you can easily\n> share your repository with someone else, and they can bootstrap from\n> the same commits.\n\nI wish that was practical for some projects.\n\nIt would be a huge improvement if git-svn could fully incorporate *all* of the metadata that it needs into native git objects (notes/tags/something). That way a git clone of a git-svn repository doesn't need to re-bootstrap anything. :-)\n\nFor example, a project that I follow has 26k branches (one per bug fix due to organizational workflow/policy). The project took five days to \"git svn clone -s\" and the re-bootstrap after blowing away the .git/svn directory is similarly painful. Why? Well, let's consider how much data must be rebuilt:\n\n$ git svn gc\n$ find */.git/svn -type f -name unhandled.log.gz -print0 | xargs -0 rm\n$ du -sh .git/svn\n445M\t.git/svn\n$ find .git/svn | wc -l\n 52467\n$ \n\nCrazy, huh?\n\ndavez\n\n\nP.S. -- To the credit of git, the space savings are incredible for this project. The svn repository is 33.6 GiB vs 133.2 MiB for git (minus git-svn and git-reflog overhead). That's ~260x!"},{"id":"169038","messageId":"20110531045324.GA13661@dcvr.yhbt.net","threadId":"27489","inReplyTo":"201105281154.25223.jnareb@gmail.com","subject":"Re: [RFD] Proposal for git-svn: storing SVN metadata (git-svn-id) in notes","fromName":"Eric Wong","fromEmail":"normalperson@yhbt.net","sentAt":"2011-05-31T04:53:24Z","receivedAt":"2011-05-31T04:53:24Z","isPatch":false,"sender":{"key":"e@80x24.org","avatar":null},"body":"Jakub Narebski wrote:\n> Eric, from what I remember you don't have time nor inclination for \n> adding new features to git-svn, is it?\n\nYes, that's mostly the case.
