It\n+will work only when it is the sole method of committing to the\n+Subversion repository.\n+\n+It is designed to export a linear git branch. However, thanks to the way\n+'git' handles source code, 'git-svndump' seems to work in other\n+conditions. For example, when branches are switched or merged.\n+\n+git-svndump provides a solution when you need to export you source code\n+in Subversion format (who would need this with git :), but do not want\n+to have all the shackles that 'git-svn init' puts on your repository.\n+\n+COMMANDS\n+--------\n+--\n+\n+'init'::\n+\tInitialize an existing git repository with additional\n+\tmetadata directories for git-svndump. The Subversion URL\n+\tmust be specified as the first non-optional command-line\n+\targument. 'git' tree-ish that correspond to the HEAD of\n+\tthat Subversion URL may be specified as the second optional\n+\tcommand-line argument.\n+\n+-f;;\n+\tgit-svndump normally declines to reinitialize the same git\n+\trepository. With the '-f' option that behavior is overridden.\n+\n+-A;;\n+--authors-file=;;\n+\tThe filename is stored, and provided as an argument to 'git-svn'\n+\ton calls of 'git-svndump sync'.\n+\n+'sync'::\n+\tCommit git revisions to the Subversion repository. If a git\n+\t is specified as an optional command-line argument,\n+\tthan all commits between the last 'sync' and that are\n+\tsend. If the argument is omitted, the HEAD of the active branch\n+\tis used.\n+\n+-A;;\n+--authors-file=;;\n+\tThe filename is provided as an argument to 'git-svn'.\n+\n+--\n+\n+BASIC EXAMPLE\n+--------------\n+\n+Contributing to a Subversion repository:\n+\n+------------------------------------------------------------------------\n+# Create your git repository, do some work and commit your changes\n+# You are working on a computer A (git.foo.org)\n+# Prepare your git repository for export (you are in the top dir)\n+\tgit-svndump-init -A .auth http://svn.foo.org/project\n+# Commit the whole branch:\n+\tgit-svndump-sync\n+# Now you go a different computer B\n+# Clone a git repo:\n+\tgit clone git.foo.org:/path/to/project.git\n+# Enter the newly cloned directory:\n+\tcd project\n+# Immediately prepare the new repository for export\n+\tgit-svndump-init -A .auth http://svn.foo.org/project HEAD\n+# Do some work and commit both locally and to A:\n+\tgit commit ...\n+\tgit push\n+# Commit the new work:\n+\tgit-svndump-sync\n+# Now you return to the computer A\n+# Reinit your repository for export!\n+\tgit-svndump-init -f -A .auth http://svn.foo.org/project HEAD\n+------------------------------------------------------------------------\n+\n+BUGS\n+----\n+\n+The HEAD of the Subversion repository is not tracked.

And I can \nexplain, why 40 '0'. That is the only reference to root commit as an \nobject that I managed to find in git - in the output of 'git-rev-list'.\n\nIf 40 '0' is not good, then it may worth to introduce a shorthand for \nit, just as we have one for 'HEAD'. 'NULL' or 'ROOT' may be. If this is \nimplemented in 'git-rev-list', there will be no need to change 'git-svn' \nat all.\n"},{"id":"45426","messageId":"4678F797.7000005@gmail.com","threadId":"8636","inReplyTo":"20070620064015.GB25840@muzzle","subject":"Re: [PATCH 2/3] 'git-svndump'","fromName":"Sergey Yanovich","fromEmail":"ynvich@gmail.com","sentAt":"2007-06-20T09:47:03Z","receivedAt":"2007-06-20T09:47:03Z","isPatch":true,"sender":{"key":"ynvich@gmail.com","avatar":null},"body":"Eric Wong wrote:\n> We could probably just implement this directly in git-svn.

They don't do \nanything themselves. They just call 'git-svn'. It works like decoupling \nin object-oriented design. Old UNIX philosophy of 'big number of small \ntools'.\n\nIf you decide to incorporate then in 'git-svn', you'll need to \ncontaminate it with knowledge of 'svndumb'. I am afraid, you'll need to \nperuse the whole file, putting 'if's here and there.\n\nBut, it doesn't really matter, which you way you go. I would be happy \njust to see this functionality in some future release of git.\n"}]}
